Description

The present invention relates to a hydraulic pump.

Hydraulic pumps include centrifugal pumps, gear pumps, vane pumps, piston pumps, screw pumps and the like.

Natural disasters such as heavy rain and heavy snow that occur in recent years are said to be caused by a large amount of carbon dioxide emissions, which is said to be one of the causes of global warming. There are increasing demands for conversion to renewable energy.

In power generation using natural energy, it is known that power is generated by using wind power, hydraulic power, or the like.

In recent years, installation locations for wind power generation have come to be found in various places.

In most wind power generation, the rotating shaft of the blade of the wind turbine is directly connected to the generator shaft using gears.

Therefore, in order to obtain a large amount of power generation, a large object with a blade size of several tens of meters is installed.

If the blades are made larger in order to obtain a large amount of power, the generation of low-frequency noise will also increase.

There is also a small wind power generator installed on the roof of the building.

In addition, there are some water turbine power generation utilizing small rivers.

It seems that various problems will occur in order to further utilize renewable energy in the future.

The amount of renewable energy such as small hydropower and wind power varies depending on the weather conditions.

In addition, problems such as fluctuations in the electric charge purchased by electric power companies and the relationship with the transmission line network due to changes in the amount of power generation due to unstable weather have been pointed out.

In order to solve these problems, the idea of local production for local consumption of electric power seems to be the best.

We will downsize wind and hydroelectric generators, store the generated power in storage batteries that are expected to develop rapidly in the future, eliminate power generation that fluctuates due to the weather by using storage batteries, and local industries and households that do not depend on power companies. Develop wind and hydroelectric generators suitable for homes, villages, and regions that can be used to charge individual electric vehicles that are becoming more widespread.

The power generation system of a conventional generator is a mechanism that generates electricity by directly transmitting the rotating force generated by other powers such as wind power, hydraulic power, and thermal power to the rotating shaft of the generator and rotating the shaft. Each machine has a generator attached to the rotating shaft.

In order to obtain power as a generator that utilizes local natural energy rooted in the region, multiple conventional small generators are installed and the generators are connected to each other to generate electricity one by one. Loss during conversion was a major issue.

In order to solve this problem, a new hydraulic pump that replaces the rotating force generated by multiple small wind power, hydraulic power, etc. with hydraulic pressure, efficiently collects hydraulic pressure, and turns one generator to generate power. It is necessary to construct a power generation system, but in order to connect and utilize it in series using a known hydraulic pump, existing centrifugal pumps, screw pumps, and almost all other pumps have a thread groove on the central rotating shaft. , Centrifugal groove, etc., which is a pump that pushes out hydraulic oil in the groove where the shaft rotates. A screw pump, etc.

In the present invention, the force obtained by the rotation of a plurality of blades that rotate under wind and hydraulic power is connected by using hydraulic oil to collect oil pressure, and one hydraulic motor is rotated by this oil pressure to operate a generator.

For this purpose, a hydraulic pump that can replace the force generated by the rotation of multiple machines with hydraulic pressure and connect them is required, and in order to efficiently connect multiple hydraulic pumps, multiple hydraulic pumps are linearly connected in series. It is necessary to install a machine, connect and rotate, and use hydraulic oil to connect each hydraulic pump to each other to increase the output.

In order to obtain hydraulic pressure by arranging and connecting multiple pumps in series on a straight line, it is necessary to arrange them as pumps that can rotate on a straight fixed shaft and obtain hydraulic pressure.

For this purpose, a hydraulic pump composed of a rotating cylindrical member with a fixed shaft as the central axis is provided as a groove or a coil spring joined to the inner surface of the cylindrical member to form a spiral groove for transporting hydraulic oil. It is characterized by having a hydraulic oil inlet and a hydraulic oil outlet that flow into the cylindrical member from the inside, and is rotated by receiving wind or water flow on the surface of the rotating tubular member on the fixed shaft. It is a hydraulic pump equipped with the blades of.

In addition, multi-stage high-pressure hydraulic pumps, which are cylindrical tubular members of different sizes, are lined up on the fixed shaft shaft, and a hydraulic oil flow path is provided in the fixed shaft shaft to accommodate small, medium and large hydraulic pumps. By using it as a pair of hydraulic pumps that can be connected and operated using hydraulic oil, unlike conventional pumps, a cylindrical member that rotates on a single straight fixed shaft is provided as a pump on the fixed shaft. It is also a multi-stage high hydraulic pump that can connect these hydraulic pumps, which are cylindrical members that can be installed in series in series.

Multiple pumps are installed in series, and the pressure between each pump generated by rotation is connected using hydraulic oil, but the conventional pump with a rotating shaft structure cannot be used because multiple pumps cannot be connected on the shaft shaft. The hydraulic pump of the present invention overcomes the technical problem of requiring a hydraulic pump that rotates on a fixed shaft shaft having a different pump structure.

Unlike conventional hydraulic pumps, the hydraulic pump of the present invention is provided with a spiral groove blade member having a groove in a cylindrical member that rotates on a fixed shaft, a spiral groove member in the shape of a coil spring, or the like, and rotates to transport hydraulic oil. It is a hydraulic pump used as a spiral groove member, provided with windmill blades and water wheel blades on the surface of the cylindrical member, and is composed of a fixed shaft shaft that supports the cylindrical member that rotates by wind power and hydraulic power.

The fixed shaft shaft that supports the cylindrical member that rotates with the windmill blades and water wheel blades forms a flow path through which the hydraulic oil that connects the connected pumps passes, but it is a part of the hydraulic pumps that are continuously installed on the fixed shaft shaft. The number of revolutions of the pump turns abnormally fast and pushes out more than the specified amount of hydraulic oil. The hydraulic oil in the pump runs short and runs idle, resulting in negative hydraulic pressure. A bypass supply flow path with an oil check valve is also a fixed shaft shaft provided in the fixed shaft shaft.

It is a cylindrical member that rotates by providing a member with a spiral groove blade and a spiral screw groove of a coil spring in the cylindrical member. When this member rotates, the hydraulic oil in the groove is pushed out and the normal flow path of the fixed shaft shaft. It is a mechanism that is pushed and discharged into the cylindrical member of another pump that is connected through the above.

Each of the series of pumps that rotate with wind turbine blades of different sizes is a multi-stage hydraulic pump with different outflow amount and pressure of hydraulic oil extruded from the pump depending on the groove width, depth, etc. of the groove member that rotates by receiving force. By arranging the pumps arranged in series in an appropriate order and connecting the obtained oil amount and oil pressure in series so that a gradually higher pressure can be obtained, the oil pressure equivalent to that of a large windmill or water wheel can be obtained. It is a pair of obtained hydraulic pumps.

Further, only the hydraulic oil inflow port portion of the coil spring portion, which is the spiral groove portion for transporting hydraulic oil in the cylindrical member, is spotted and fixed on the inner surface of the cylindrical member, and the cylindrical member rotates at an abnormally high speed to inside the cylindrical member. When it falls into high hydraulic pressure, the coil spring shrinks and the groove becomes narrower, and the amount of hydraulic pressure that pushes out the hydraulic oil decreases, which prevents the wind turbine from rotating at high speed due to a gust of wind, etc., and prevents the hydraulic pump from becoming abnormally high hydraulic pressure. It is designed so that it can be avoided, and a coil spring member that expands and contracts when the inside of the cylindrical member receives a hydraulic pressure higher than the specified value is used.

Also, in the case of a pump used as a hydraulic pump provided with a spiral groove blade member as a groove member for pushing out hydraulic oil into the tubular member, the spiral groove blade member is placed on the inner surface of the cylindrical member only in the vicinity of the hydraulic oil inflow port. It is a spiral groove blade member that shrinks variably even when it is fixed by spotting and falls into high hydraulic pressure due to abnormal high-speed rotation.

With high hydraulic pressure obtained by hydraulic pumps of multiple multi-stage cylindrical members that rotate around the fixed shaft shaft, the cylindrical member provided at the rear end of the fixed shaft shaft was rotated and used as a rotor member of the generator. It is a pump of a cylindrical member of the present invention, and is a hydraulic pump that also serves as a motor that rotates by hydraulic pressure.

The feature of the hydraulic pump of the present invention is a hydraulic pump that can be used by arranging and connecting a plurality of small hydraulic swirl pumps, screw pumps, etc. of multi-stage high-pressure hydraulic pumps of different sizes on one fixed shaft. By connecting the machines side by side, it is possible to gradually obtain a large oil pressure, and unlike large blade windmills and hydraulic pumps, it can be easily installed anywhere, and the structure is extremely simple and can be manufactured at low cost. It is a hydraulic pump that can utilize natural energy such as local rivers, coastal wind power, and hydraulic power, which have been overlooked in the past.

In addition, it is easy to connect multiple multi-stage high-pressure hydraulic pumps that support the required power, and by installing and connecting the number of pumps that match the required power amount, which differ depending on the regional application, on the fixed shaft shaft. Wind and hydroelectric power generation suitable for the region and application has become possible.

The basic structural drawings 22 and 23 of each pump are shown.

The fixed shaft that supports the cylindrical member, which is a pump that uses a spiral groove blade member and a pump that uses a coil spring that expands and contracts, has a flow path of hydraulic oil that flows between each of the hydraulic pumps that are connected in series on the shaft. FIGS. 20 to 27 and 31 show the flow of hydraulic oil flowing between the hydraulic pumps serially connected by the provided shaft shaft reference numeral 4.

The hydraulic pump of the present invention includes a hydraulic centrifugal pump and a screw type pump using a coil spring. The hydraulic centrifugal pump of the present invention will be described first.

A hydraulic pump consisting of a cylindrical member that rotates around a fixed shaft shaft. A partition plate disk that separates the cylindrical member into two chambers is provided in the center of the cylindrical member by joining it to the inner surface of the cylindrical member. Is equipped with a disk with swirl groove blades for transporting hydraulic oil, which is a disk with a plurality of swirl groove blades aligned in the same direction on the front surface and a plurality of swirl blades aligned in a direction different from the front surface, and is fixed. Explanation of a swirl pump provided with a variable swirl-shaped groove blade plate material that deforms and shrinks when the inside of this pump falls into a certain level of high-pressure oil in a hydraulic pump having a hydraulic oil inlet and a hydraulic oil outlet at both ends of the shaft. Figures 21, 22, 23, 24, 25, 26, 27.

A spiral hydraulic pump in which a cylindrical member rotates on a fixed shaft by receiving wind power and hydraulic power with blades.

The hydraulic oil used in the pump is a hydraulic centrifugal pump that is supplied and operated from the flow path of the hydraulic oil provided in the fixed shaft.

Fig. 23, 24, 25 in which a disk of a partition plate that separates the cylindrical member into two chambers is provided in the center of the cylindrical member of the centrifugal pump, and groove blades having different shapes of the spiral groove blades are provided on the front and back of the disk member.

FIG. 21 is a centrifugal pump that rotates on a fixed shaft with a wind turbine blade and a water turbine blade provided on the surface with a sealed cylindrical member code 16.

The cylindrical member rotates clockwise in response to wind power, hydraulic force, etc., and the hydraulic oil in the spiral groove blade on the surface of the disk-shaped member in the cylinder is pushed by the centrifugal force or the spiral groove blade, and is supplied from the fixed shaft shaft to the cylinder. Arrow sign that is pushed out and flows to the back surface of the shape 6 Fig. 21 Fig. 22.

Disk partition plate in the cylindrical member FIGS. 22 and 23, which are guided by a spiral groove blade provided on the back surface of the disk member of reference numeral 19, and flow with pressure to the hydraulic oil outlet in the shaft shaft.

This hydraulic oil flows as hydraulic oil with pressure to the adjacent multi-stage hydraulic centrifugal pumps provided on the fixed shaft shaft, and is discharged to the centrifugal groove blades in the pump.

The size of the centrifugal pump is gradually increased by arranging and connecting them on a fixed shaft shaft, and using the high hydraulic oil obtained by operating, the generator on the shaft shaft at the rear end is rotated. Figure 22 that generates electricity.

If the pumps installed continuously on the fixed shaft are made larger, the force applied to the pumps will be larger and heavier during rotational operation, but this can be dealt with by increasing the width of the wind turbine blades and water turbine blades.

As mentioned above, it was stated that the hydraulic hydraulic oil generated by the swirl pump passes through the flow path in the shaft shaft, connects each swirl pump, uses it as a pair of hydraulic pumps, and rotates the generator with the generated hydraulic pressure, but the following is a supplement. When the pressure inside the pump becomes higher than the specified pressure, the spiral groove blade member deforms and shrinks in order to avoid damage to the cylinder member, which is a hydraulic pump, because the inside of the cylinder member becomes highly hydraulic due to abnormally high rotation due to a gust of wind etc. It is described in FIGS. 24, 25, 26, and 27 that when the groove blade that pushes out the hydraulic oil is deformed and falls into high-speed rotation, the flow rate is small and the groove blade is pushed out.

A partially enlarged perspective view of the spiral groove blade member is shown in FIGS. 24 and 25, but the joint portion of the spiral groove blade member is spotted and fixed only in the vicinity of the cylindrical member hydraulic oil inlet portion. ..

The shape of the spiral groove blade member in FIG. 24 is the shape of the groove blade member in the hydraulic state during normal operation, and is a spiral groove blade member in a state where it rotates and pushes out hydraulic oil supplied from the shaft shaft to operate. ..

The hydraulic oil extruded by the spiral groove blade member is guided by the spiral groove blade member provided on the upper and lower surfaces of the disk and discharged from the shaft shaft hydraulic oil outlet into the adjacent spiral pump.

The spiral groove blade member provided on the back surface of the partition plate member of the disk rotates and collects hydraulic fluid at the shaft shaft hydraulic oil outlet at the center, unlike the spiral groove blade member provided on the front surface. It is a groove blade member having the shape of.

It is a spiral groove blade member that guides the hydraulic oil that has been pushed out by the spiral member on the surface to the hydraulic oil outlet with pressure.

The swirl groove member of FIG. 24 described above is the shape of the groove blade of the swirl member that operates in the pressure range of the hydraulic oil obtained by rotation with normal wind power.

In power generation using wind power, a strong wind such as a typhoon or a gust sometimes occurs, so the pump rotates at high speed and the inside of the pump falls into an abnormally high hydraulic pressure above the specified value, and the centrifugal pump groove blade member becomes high hydraulic pressure. In response to this, Fig. 25 and Fig. 27 show that the deformation, shrinkage, bending, and turning radius become smaller.

When the groove member of the pump shrinks and the turning diameter of the member becomes smaller, the amount of oil that pushes out the hydraulic oil decreases. Fig. 27.

Fig. 24, 25, 26, 27 are variable spiral groove blade members that can prevent the pump from being damaged because the amount of oil pushed out is small even when the centrifugal pump rotates at high speed and the hydraulic pressure exceeds the specified value.

In the front view of the spiral groove blade member of the centrifugal pump, FIG. 26 is a diagram showing the shape of the spiral groove blade during normal operation.

In the front view of a groove blade with a variable shape due to an abnormally high oil pressure inside the pump due to an abnormally high oil pressure inside the hydraulic pump, a high load is applied to the groove, and the spiral groove blade member has a smaller rotation diameter. FIG. 27 shows a groove blade member in which one end of the base of the spiral groove blade shape is spotted and joined to the partition plate disk and the cylindrical member, and the groove blade member changes when a high hydraulic pressure exceeding a certain specified value is received except for the spotted portion. Is.

The swirl pump that turns the swirl pump on a fixed shaft to obtain hydraulic pressure has been described, but the following describes that a screw pump using a coil spring is used to generate power, and multiple hydraulic pumps rotate on the shaft to gradually increase the hydraulic pressure. Based on a hydraulic screw pump using a coil spring having a spiral groove of a hydraulic pump that obtains hydraulic pressure, the basic structure will be described in detail below with reference to FIGS. 1 and 2.

FIGS. 1 and 2 are a side perspective view of the basic structure of the hydraulic screw pump of the present invention and a cross-sectional perspective view showing a coil spring having a spiral groove in the cylindrical member, and the cylindrical member of the hydraulic screw pump provided on the shaft shaft reference numeral 4. At symbol 1, a spiral groove member is provided in this member, and the hydraulic screw pump that pushes out the hydraulic oil in the groove rotates as shown by the clockwise arrow symbol 5.

A shaft shaft code 4 is provided in the fixed shaft shaft with a flow path through which hydraulic oil flows in and out at both ends of the groove code 2 in contact with the fixed shaft shaft code 4.

The shaft shaft hydraulic oil inlet / outlet is closed to form a hydraulic oil flow path during normal operation. Fig. 2.

As shown by the arrow code 6 shown in FIG. 2, when the hydraulic oil flows from the right flow path port to the groove code 2 and the cylindrical member of code 1 which is a hydraulic screw pump rotates, the hydraulic oil in the groove is pushed and pressure is applied. , It flows from the hydraulic oil flow path port in the left shaft shaft to the hydraulic screw pump connected to the groove in Fig. 6.

Since the groove spacing is wide as shown in the groove code 2-1 in Fig. 6, the cylindrical member of code 1 which is a hydraulic screw pump makes one rotation and the flow rate to push out is large, and the hydraulic oil that has flowed in with pressure is further applied with pressure. Extrude and release.

In this way, it is a pair of multi-stage high-pressure hydraulic pumps in which a plurality of pumps of different sizes are arranged on a fixed shaft shaft and the pumps are arranged and connected so that a gradually high hydraulic pressure can be obtained.

In the present invention, a small hydraulic screw pump is rotated by wind power, and a generator provided at the rear end of a fixed shaft shaft is rotated by an oil pressure obtained by connecting a plurality of machines in series. FIGS. 10, 19, 20.

A pair of multi-stage type hydraulic screw pumps, which are cylindrical members that rotate with blades that receive wind and hydraulic power, are installed on this fixed shaft shaft as large ones in proportion to the size of the blades, and gradually large screw pumps are connected in series. Used as a high-pressure hydraulic pump.

Further, it is a screw pump of the present invention that can be connected with hydraulic fluid even if the external shape of the hydraulic screw pumps that are continuously installed and connected is not the same size or different sizes of multi-stage hydraulic pumps but have different rotation speeds. ..

In this way, multiple machines are installed on one fixed shaft and connected to each other and used as a pair of hydraulic screw pumps. High hydraulic pressure can be obtained by connecting multiple pumps despite their small size. It is a hydraulic screw pump that can turn a generator with oil.

In the second embodiment, it is described that the hydraulic screw pump of the present invention is used as it is to rotate the generator as a hydraulic motor.

The hydraulic screw pump of the present invention is provided with a spiral groove member for transporting hydraulic oil in a rotating cylindrical member.

The amount of hydraulic oil extruded in one rotation differs depending on the depth width of the groove.

Fig. 11, 12, 13 As a pair of multi-stage hydraulic screw pumps in which screw pumps of different sizes are arranged on a fixed shaft shaft and gradually installed with large wind turbine blades, high-pressure hydraulic pressure is obtained and the screw pump installed at the end of the fixed shaft shaft A cylindrical member that rotates by discharging hydraulic oil with high hydraulic pressure to the inner groove is used as a hydraulic motor. Fig. 19 Generator 8.

A pair of hydraulic screw The high-pressure hydraulic oil pushed out by the rotation of the pump is discharged into the groove in the cylindrical member at the end of the fixed shaft shaft, and if this groove is shallow and the groove spacing is narrow, it receives pressure and rotates at high speed. Will be.

This rotating cylindrical member is used as the rotor member of the generator. Fig. 19 After rotating the cylindrical tubular member as the rotor member of the generator with the generator code 8, the high-pressure hydraulic oil becomes low-pressure and the hydraulic oil tank. Return to.

As described above, it was invented so that multiple hydraulic screw pumps can be connected using hydraulic oil, but when high hydraulic pressure is applied to the screw pump groove, this screw pump also becomes a hydraulic motor, and it is linear. Multiple hydraulic screw pumps are lined up on a fixed shaft shaft, and the hydraulic oil with high hydraulic pressure that can be gradually increased to high hydraulic pressure is discharged into the groove in the cylindrical member provided at the end of the rear shaft shaft to rotate the generator. By using it as a child, it is a power generation system that can produce a small but extremely efficient generator.

In Example 3, each member constituting the hydraulic screw pump of the present invention will be described in more detail, but here, a hydraulic screw pump using a wind turbine blade will be described.

FIGS. 1, 2, 3 Rotating cylindrical member code 1 Coil spring-shaped spiral groove member code 2-1 having a spiral thread groove on the inner surface, groove member code 2 provided with code 2-2, drawings 3, 4, 7 A windmill blade is provided around the surface of this cylindrical member, a coil spring-shaped spiral screw groove is provided in the cylindrical member, a groove member, a hydraulic screw pump consisting of a fixed shaft shaft member code 4, and only the numbers with the following codes are described.

For the cylindrical member 1 to be a hydraulic pump, a cylindrical cylindrical pipe made of steel that can withstand the size of the blades that rotate in response to the wind is used.

It is a transport groove member 2 that pushes out hydraulic oil provided with coil-shaped members 2-1 and 2-2 having screw grooves in the cylindrical member.

As shown in the figure described, the screw groove width is narrow, and the amount of hydraulic oil in the groove is different depending on the size and width of this width, and the amount of hydraulic oil transported in one rotation is different.

Further, even if the number of turns of the coil spring is large, if the groove width is narrow, the amount of hydraulic oil extruded and discharged in the groove is also small.

As shown in FIGS. 3, 4, and 7, the amount of oil pushed out by the hydraulic oil of the hydraulic screw pump when one rotation is made changes depending on the width between the grooves, the depth of the grooves, and the like.

Therefore, in the present invention, the hydraulic screw pumps provided on a plurality of fixed shafts have the hydraulic pressure of the coil spring whose groove width and depth are adjusted so that the amount of oil to be extruded increases in the order of arrangement even if the rotation speed is the same. It is a screw pump.

If the pumps are arranged on the fixed shaft so that the amount of oil to be pushed out increases in order, the hydraulic pressure gradually increases, but the load applied to the cylindrical member increases and the rotation of the blades becomes heavy.

In order to eliminate this load, the wind turbine blades are enlarged to correspond to Fig. 10,11,12.

The hydraulic screw pump of the present invention operates several pumps side by side on a fixed shaft, and connects each pump using hydraulic oil. Since they are connected side by side, the wind turbine blades naturally become large wind turbine blades that match the amount of oil to be pushed out.

In the present invention, a coil spring-shaped spiral groove member having a screw groove is used, but a cylindrical member may be provided by directly processing a screw groove on the inner surface of the cylindrical member.

The fixed shaft shaft 4 that supports the cylindrical member that is rotated by the wind turbine blades is a shaft of a round steel shaft that is strong and thick enough to withstand the force generated during rotation.

It is a fixed shaft shaft made of a material with a strength that can withstand the operation of hydraulic screw pumps connected in series with the fixed shaft shaft 4.

FIG. 2 shows a flow path port through which the hydraulic fluid passes by arrow symbol 6 in FIG. 2, which is connected side by side on a fixed shaft and in which hydraulic fluid from an adjacent hydraulic screw pump flows in the screw pump.

The hydraulic screw pump of the present invention utilizes as a hydraulic motor a cylindrical member that is rotated by hydraulic oil with high hydraulic pressure extruded from this screw pump at the end terminal of the fixed shaft shaft provided with multiple hydraulic screw pumps on the fixed shaft. However, although power is being generated, it is not always necessary to provide it on the shaft terminal on the shaft, and a hydraulic hose may be used to generate power using an existing hydraulic motor at a remote location.

Further, as the motor for generating power, a commercially available hydraulic motor or the like may be used instead of the hydraulic motor utilizing the hydraulic screw pump of the present invention.

The blades of the wind turbine that rotate the hydraulic screw pump and the hydraulic centrifugal pump in the drawings described and described are not the blades in the shape of the wind turbine as shown in the above figure, but may be those using other propellers, fans, etc. with multiple blades. good.

In the above, power generation using wind power was described, and in order to obtain high-pressure hydraulic hydraulic oil, the size of the wind turbine blades was gradually increased to increase the diameter of the blades, but the hydraulic screw pump of the present invention was used for small and medium-sized rivers. When used as a screw pump for a hydroelectric generator, the turbine blades lined up on the fixed shaft have the same diameter of the rotating turbine blades, but the amount of water received by the turbine blades is different. It is a generator that utilizes hydraulic power by adjusting the above.

Example 4 is FIG. 13 of an embodiment of a water turbine generator using the hydraulic screw pump of the present invention for a general small and medium-sized river, which describes an embodiment of using the hydraulic screw pump of the present invention for a hydroelectric generator.

Figure 13 shows the implementation of power generation by suspending a water turbine generator with a wire rope 12 between small and medium-sized river embankments, floating the water turbine in the river, and turning the water turbine.

The shaft member that supports the water turbine is the fixed shaft of the hydraulic screw pump of the present invention described above.

The diameter of the turbine is the same, but the width of the turbine is different.

According to the width of the turbine, the size of the hydraulic screw pump is also large and connected.

The larger the width of the water wheel, the larger the surface that receives the amount of water, and the larger the rotational force applied to the hydraulic screw pump. This is a hydraulic screw pump that utilizes the water wheel of the present invention to form a pair of hydraulic screw pumps by connecting them using a hydraulic screw pump that is also enlarged by enlarging and installing.

It is a buoyancy material 14 provided on the water vehicle side and is a buoyancy member having a function of a guide for guiding a water flow.

A buoyancy material is provided to cope with the fluctuating water level of the river. be.

By stretching the wire rope 12 between the embankments and suspending the water turbine, a water turbine generator that utilizes constant hydraulic power regardless of fluctuations in the water level of the river can be created.

It can be installed simply by stretching the wire rope 12 between the embankments, and in rivers with narrow rivers, irrigation canals, drainage canals, etc., water turbines can be hung and installed using steel pipes, and it is stable using small and medium-sized rivers with low installation costs. Power can be generated.

In Example 5, the application installation status of the hydraulic screw pump of the present invention is shown in FIGS. 14 and 15.

The figures of the hydraulic screw pump wind turbine blades in FIGS. 14 and 15 are drawn using a schematic diagram.

FIG. 15 is a drawing 15 in which a fixed shaft is provided and supported by a rope in order to be fixed between the columns 15 standing on the ground.

The hydraulic screw pump of the present invention is provided between the pillars, and a wind turbine blade having a diameter of about 60 cm to 2 m is used.

The hydraulic screw pump may not always be installed horizontally but may be installed and used as shown in FIG.

In Example 6, regarding the hydraulic motor, the difference between the hydraulic motor utilizing the hydraulic screw pump of the present invention and the conventional hydraulic motor will be described.

The conventional hydraulic motor is a hydraulic motor that rotates a gear shaft and a screw shaft by applying hydraulic pressure to a gear gear or a screw groove with hydraulic oil having hydraulic pressure.

In the present invention, the pump used as a hydraulic screw pump rotates a cylindrical member on a fixed shaft shaft as a central axis by applying hydraulic pressure to a screw groove provided in the cylindrical member and applying hydraulic pressure to the screw groove. It is a hydraulic motor that is made to rotate by discharging high-pressure hydraulic oil from a fixed shaft.

Highly hydraulic hydraulic oil is discharged from the fixed shaft to the inner groove of the cylindrical member, and the cylindrical member can be rotated by hydraulic pressure. It is a screw pump that can also be used as a hydraulic motor. ..

The above-mentioned screw pump is used as a cylindrical member that rotates by the hydraulic pressure at the rear of the fixed shaft shaft with high hydraulic hydraulic oil generated by a pair of hydraulic screw pumps that are provided and connected on a fixed shaft. The generator 8 in FIG. 19, which is a rotor of a generator provided with a magnet on the surface of a cylindrical member.

In the seventh embodiment, the spiral groove portion for transporting the hydraulic oil that pushes out the hydraulic oil of the hydraulic screw pump will be described.

As described above, the cylindrical member may be used as a cylindrical member in which a spiral groove for pushing out hydraulic oil is directly machined on the inner surface of the cylindrical member.

The amount of hydraulic oil extruded varies depending on the depth of the spiral groove that makes one rotation, the width of the groove, and so on.

The groove for pushing out the hydraulic oil may be used as a coil-shaped spiral groove member by incorporating it into the cylindrical member.

A coil spring member that expands and contracts when a hydraulic pressure exceeding a certain level is applied to the spiral groove member that pushes out the hydraulic oil is used.

When a coil spring-like spiral member that expands and contracts under pressure is used, the width of the groove of the spiral spring that pushes out the hydraulic pressure shrinks and narrows when the inside of the cylindrical member exceeds the specified hydraulic pressure, and the amount of hydraulic oil that rotates and pushes out is reduced. In order to push out, even if the cylindrical member receives strong wind, gust of wind, etc. and falls into high-speed rotation, the hydraulic pressure inside the cylindrical member is suppressed from becoming abnormally high oil pressure and the cylindrical member is rotated to high pressure. It can be avoided from damage caused by.

In response to strong wind, the cylindrical member rotates at a higher speed than the specified rotation, and the pressure to push out the hydraulic oil in the cylindrical member becomes extremely high. A coil spring used as a groove, and a spiral coil spring that can be easily expanded and contracted by being spotted and fixed at one point on the inner surface of a cylindrical member near the hydraulic oil inlet.

Also, when used as a hydraulic pump for wind power generation, constant oil pressure can be maintained by expanding and contracting the spiral groove width of the coil spring due to the pressure at different rotations due to wind power, so constant oil even if the blades rotate at high speed due to strong wind. It is also possible to maintain the pressure and keep the rotation of the generator stable to avoid excessive power generation caused by fluctuations in wind power.

As described above, the change in hydraulic pressure that changes depending on the strength of the wind is used in a hydraulic screw pump using a spiral coil spring member having a constant hydraulic pressure adjusting function, and also as a rotor member of a generator that rotates hydraulically.

In Example 8, each hydraulic screw pump describes the flow of the obtained hydraulic oil and the correspondence of each pump that has fallen into an abnormally high hydraulic pressure.

Pumps arranged in series are gradually formed into a large shape and arranged in order with an appropriate size, and a spiral coil spring groove member that expands and contracts is used so that the obtained oil pressure can be gradually and efficiently obtained at a high pressure. But there is.

Basic structure of the present invention As shown by the arrow 5 indicating the rotation of FIG. 1, the coil spring-shaped spiral groove member rotates on the shaft of FIG. 2.

The hydraulic oil in the spiral groove is pushed out by the coil spring-shaped spiral groove member, and flows into the screw pumps connected adjacently as shown by the arrow symbol 6 indicating the flow of the hydraulic oil in Fig. 2 and is discharged into the cylindrical member.

The coil-shaped spiral groove member having a spring function that expands and contracts is a spring member that expands and contracts with a strength that can withstand the oil pressure that can rotate the rotor of the generator that is the load, and the oil pressure in the pump during normal power generation operation. Is a spiral groove member made of a spring material that does not expand and contract.

Occasionally, the weather may change suddenly, resulting in a temporary gust of wind.

In such a case, the rotation of the wind turbine blade falls into high-speed rotation.

During a gust in proportion to the speed of rotation of the blades, a large hydraulic pressure is generated in the pump and applied to the cylindrical member.

Normally, it is a coil spring-like spiral groove member in a cylindrical member that can cope with the rotation of the wind turbine that changes slightly depending on the weather, but sometimes there is a phenomenon that a gust of wind causes the rotation of the wind turbine to rotate at high speed, so a device to protect the hydraulic pump is devised. I needed it.

In strong winds, existing large-scale wind power generators, etc. handle the amount of wind that hits the wind turbine blades by changing the pitch angle of the wind turbine blades to allow some wind to escape. However, the screw pump in the present invention is described above. In order to avoid damage to the hydraulic pump due to the high pressure inside the pump due to the high-speed rotation of the wind turbine, a coil-shaped spiral groove member with a spring expansion / contraction function that contracts when a certain specified amount of oil pressure is applied is used. When the cylindrical member falls into high-speed rotation, the spiral coil groove shrinks under the load of high oil pressure in the cylinder and the groove width narrows, reducing the amount of hydraulic oil pushed out and forming a cylindrical shape. This is to avoid damage to the pump of the member.

Further, the spiral groove member of the telescopic coil spring also has a hydraulic pressure adjusting function of gradually increasing and pushing out different hydraulic pressures flowing out from between the connected pumps.

Up to Example 8, a plurality of hydraulic screw pumps of the present invention are provided on a fixed shaft shaft as a pair of hydraulic screw pumps provided on a fixed shaft shaft having a certain thickness, but the diameter of the fixed shaft shaft is large. An example in which the thickness is adjusted according to each hydraulic screw pump will be described with reference to FIG.

The figure shown in FIG. 19 is FIG. 19 of the basic structure of a multi-stage high-pressure hydraulic pump in which small, medium, and large hydraulic pumps are connected in series to form a pair of hydraulic screw pumps. It is a schematic cross-sectional view of a part of the side surface provided with.

A multi-stage high-pressure hydraulic pump that connects small, medium, and large hydraulic screw pumps and receives wind and hydraulic power to rotate each pump, but can press hydraulic fluid to obtain high-pressure hydraulic fluid even though the rotation is the same or different. FIG. 19.

As the diameter of the wind turbine blades increases, a twisting force is applied to the fixed shaft shaft in addition to the rotational force.

This twisting force is applied as a large load to the spiral groove member of the coil spring of the screw pump.

In order to reduce the load generated due to this twisting phenomenon, the diameter of the coil spring spiral groove member should be increased to disperse the load.

In order to cope with this torsional force, as shown in FIG. 19, the fixed shaft shaft has a diameter and size that can correspond to the size of the wind turbine blade.

A plurality of hydraulic screw pumps are provided on the fixed shaft shaft, but the hydraulic screw pump is used according to the size of the wind turbine blades, and the fixed shaft shaft is also a shaft diameter shaft having a thickness suitable for each pump.

In the tenth embodiment, FIG. 20 describes the flow path of the hydraulic fluid and the supply / supply hydraulic fluid provided in the fixed shaft.

The fixed shaft shaft shown in FIG. 20 is a fixed shaft shaft that connects the blades that rotate in response to the wind as large blades gradually according to the size of the blades, and the shaft diameter is made thicker and larger. It is a cross-sectional schematic diagram of.

As shown in Fig. 20, the large and small wind turbine blades are connected and arranged as a wind turbine hydraulic screw pump that gradually obtains high pressure hydraulic pressure. The amount of air that hits the blades of each pump changes, and the rotation of each hydraulic pump may differ.

For this reason, the difference in the rotation speed of each pump may cause the pressure in the screw pumps of the connected wind turbine blades to rotate faster than in the screw pumps before and after the continuous arrangement, so the supply of hydraulic fluid may catch up. It runs idle and oil bubbles are generated, the deterioration of the hydraulic fluid progresses, the hydraulic pressure in the pump becomes unstable, and the pressure inside the pump may become negative.

The hydraulic pressure of the screw pumps lined up gradually gained high pressure, but as mentioned above, the supply of hydraulic oil due to uneven rotation of each wind turbine was prevented from catching up and becoming negative pressure, resulting in negative pressure. In this case, a flow path that is sucked from the hydraulic oil supply supply flow path 6-1 and flows into the pump via the return prevention valve 6-2 is provided in the fixed shaft shaft. FIGS. 20, 30 and 31.

The flow paths 6-1 and 7-8 for supplying and supplying hydraulic oil to each hydraulic screw pump provided in the fixed shaft, are provided with hydraulic return prevention valves 6-2 in each supply flow path.

The return prevention valve 6-2 is a valve member 6-2 that opens with negative pressure when the supply of hydraulic fluid from the hydraulic fluid flow path in the pump cannot catch up and runs idle and the inside of the pump falls into a negative pressure state. , The valve of the flow path of the hydraulic oil to be supplied by suction replenishment. It is a valve member 6-2 that does not return.

By providing the hydraulic oil supply supply path 6-1 and 7-8 return prevention valve member 6-2 in the fixed shaft, the rotation of each pump will be different, and even if the oil pressure that can occur is different, unevenness will occur. The oil pressure can be obtained by ensuring the flow of hydraulic oil that does not exist.

By providing the above-mentioned shaft shaft structure, hydraulic oil return prevention valve member, etc., it is possible to alleviate the unevenness of power generation that changes greatly due to changes in the wind, which is a drawback of small wind turbine power generation.

An embodiment in which a bouncing wheel that rotates hydraulically is provided at the rear of a pair of hydraulic screw pumps of the present invention will be described.

The flywheel flywheel is based on the principle of rotation of a heavy disk with a large moment of inertia, and can be used as an energy storage device that suppresses sudden fluctuations in the rotation speed, stores rotational energy, and absorbs and releases it as needed.

The disadvantage of power generation using wind power is that the rotation of the wind turbine is not constant due to the strength of the wind, so the fluctuation of the force applied to the blades is particularly large in a small wind turbine, which leads to an extreme change in the voltage of the generator.

In the case of a large-scale wind power generation with a large blade diameter, even if the wind is strong or weak, the blade diameter is large as it is, so the inertial force works and the rotation speed does not fluctuate and can rotate smoothly.

Small wind power generation has the disadvantages that the blade diameter is small, the strength of the wind is strong and weak, and the rotation speed fluctuates greatly.

In order to make up for this shortcoming, the hydraulic pressure obtained from each hydraulic screw pump is used to rotate the bouncing wheel, and it rotates stably with little fluctuation due to inertial force without being affected by the rotation speed of different wind blades depending on the strength of the wind. By using a hydraulic pump as a hydraulic motor for the rotor of a generator, it is possible to obtain constant voltage power generation with little change.

Even if the rotation speed changes drastically due to the strength of the wind, which is a drawback of small wind turbines, and the hydraulic pressure changes, in order to rotate the bouncing wheel with hydraulic fluid, it is transmitted from other power transmission members that rotate the bouncing wheel, such as gears and belts. It is a bouncing vehicle that rotates with hydraulic fluid that has little power loss and can make up for the shortcomings of small wind turbines.

In the hydraulic screw pump using the bouncing wheel of the present invention, the bouncing wheel is provided and used as a rotor of a rotating generator. It may be used as a wind turbine with little change in rotation due to.

A spiral groove portion for hydraulic oil transportation is formed on the inner surface of the cylindrical member, and different spiral groove members facing the hydraulic oil transport spiral groove member in the hydraulic pump are symmetrically present in the pump of the cylindrical member. Figure 32 Figure 33 to be described.

In Example 12, the shape of the spiral groove for hydraulic oil transport is symmetrical with respect to the inner surface of the cylindrical member in the hydraulic pump composed of the cylindrical member rotating around the fixed shaft of the present invention. When the cylindrical member rotates, hydraulic oil flows in from the hydraulic oil flow path openings at both ends of the cylinder, is pushed by the spiral groove, and pressure is applied to the center of the cylindrical member, from the outlet of the fixed shaft at the center of the cylindrical member. Hydraulic oil flows through the connected hydraulic pump.

In the case of a hydraulic pump in a spiral groove for hydraulic oil transportation in a cylindrical member, one of the rotating cylindrical members is pushed by the spiral groove for hydraulic oil transportation and the hydraulic oil transported is pushed to the other of the cylindrical members with pressure. A large oil pressure is applied to the hydraulic oil seal in the cylindrical shape, and the oil flows from the fixed shaft outlet to the other connected hydraulic pumps. At this time, the hydraulic oil may leak from the oil leak prevention oil seal of the cylindrical member.

When the cylindrical member rotates, the hydraulic oil is transported in the groove to the bias inside the cylindrical member, resulting in high hydraulic pressure. The hydraulic groove for transporting hydraulic oil in the cylindrical member, which is also one of the causes of oil leakage, is provided symmetrically as different grooves facing each other, and when the cylindrical member rotates, the transport spiral groove pushes the hydraulic oil to the center. When the cylindrical member rotates, hydraulic oil is pressed from both ends of the cylindrical member to become highly hydraulic at the center of the cylindrical member, and is pushed out from the fixed shaft outlet at the center of the cylindrical member to be discharged.

As described above, the hydraulic fluid obtained by rotation is high in the center by providing symmetrically different spiral groove members on the inner surface of the cylindrical member and extruding the hydraulic oil from both ends of the cylindrical member to the center. It exists as hydraulic pressure and has a structure that can prevent oil leakage of hydraulic fluid by reducing the pressure applied to the oil leakage seals provided at both ends of the cylindrical member due to high hydraulic pressure.

Due to high-speed rotation due to a gust of wind, the cylindrical member will rotate more than specified, and in the case of the hydraulic pumps in Examples 1 to 12, the hydraulic pressure obtained by rotation from one side of the cylindrical member to the other side will be applied. It became high pressure and was discharged from the flow outlet to other connected pumps.

Therefore, the pressure of the hydraulic oil of high hydraulic pressure is applied to the oil seal of only one of the cylindrical members.

At this time, if the hydraulic pump rotates more than specified, the hydraulic oil may become high pressure and the hydraulic oil may leak from the oil leak prevention oil seal.

In the twelfth embodiment, in order to eliminate the drawback of oil leakage due to high-pressure hydraulic pressure due to abnormal rotation of only one of the cylindrical members, the hydraulic oil transport spiral grooves are symmetrical to each other. When the cylindrical member rotates by being installed in the cylindrical member, hydraulic oil is pushed from the spiral groove members at both ends of the cylindrical member to generate a high hydraulic pressure in the center, and the hydraulic pump is generated at both ends of the cylindrical member. The oil pressure applied to the hydraulic oil is reduced in the provided oil seal.

The arrow 28 in FIG. 32 indicates that when hydraulic oil enters from both ends of a cylindrical member that is a hydraulic pump and the hydraulic pump rotates, the hydraulic oil is pushed to the center with hydraulic pressure, and is connected with pressure from the outlet of the fixed shaft shaft. Figure 32.33 shows the flow of hydraulic oil discharged to both ends of the hydraulic pump.
