Moreover, considering that the produced energy is eco-friendly, non-polluting energy, it is rapidly spread worldwide. It is expected to be expanded to.

Wind power generators are classified into lift and drag types according to the shape of the windmill blades.In Korea, there are few regions where strong winds blow constantly for a long time depending on local environmental conditions, so it is difficult to rotate windmills using small wind pressure. It is efficient to use a suitable drag wind turbine.

In the case of such a drag wind power generator, if the height of the blade, that is, the length of the blade in the axial direction of the column, increases, the amount of force received by the wind may increase, but the weight of the blade is heavy due to the increase in the size of the blade. In addition to the weight of the wings and the weight of the wings, the weight of the frames to hold the wings is inevitably increased.In this case, there is a disadvantage in that there are limitations in material and composition in reducing the weight of the wings instead of increasing the size of the wings. have.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings FIGS. 1 to 11C, and the same reference numerals are assigned to the same components in FIGS. 1 to 11C. On the other hand, in each drawing, a configuration that can be easily understood by those in this field from a general technique, and an operation and a detailed description thereof have been simplified or omitted, and parts related to the present invention are mainly illustrated.

1 is a perspective view of a fluid generator according to a first embodiment of the present invention, and FIG. 2 is a front view of the fluid generator shown in FIG.

1 and 2, the fluid generator 10 according to the first embodiment of the present invention is for efficiently using the wind resistance for power generation without increasing the size of the blades, and the upward airflow forming body 20, It consists of a rotating shaft 40, a spiral blade 30 and a generator 120.

A reinforcing bar (not shown) for reinforcing the fluid generator 10 may be added inside the fluid generator 10.

The rising airflow forming body 20 is installed on the rotating shaft 40 as a component that performs the function of the body in which the spiral blades 30 are installed.

In addition, the ascending air flow forming body 20 has a main characteristic in that it is configured to improve power generation efficiency by forming an upward air current without passing all of the wind blown by the interaction with the spiral blades 30.

To this end, the upward airflow forming body 20 is configured to have a substantially conical shape as the outer diameter of the lower part is formed larger than the outer diameter of the upper part.

The rotation shaft 40 is a component installed in the rising air flow forming body 20, and performs a function of transmitting the rotational force transmitted to the rising air flow forming body to the generator. Here, the rotating shaft 40 is installed to be inserted into the shaft insertion hole formed in the center of the rising airflow-forming body, but the installation form is not limited thereto and may be installed in various forms.

The spiral blades 30 are formed in a spiral form from the bottom to the top along the outer circumferential surface of the rising airflow forming body 20, and as shown in FIG. 1, a plurality of spiral blades 30 are arranged at an isometric angle.

In particular, the spiral blade 30 is formed such that the width in the horizontal direction gradually increases from the bottom to the top so that drag can be effectively applied from the rising air current. Here, the width in the horizontal direction means the distance from the portion connected to the upward airflow forming body 20 of the spiral wing 30 to the outer edge of the spiral wing.

And, the degree of increase in the width in the horizontal direction of the spiral wing 30 is similar to the reduction value of the outer diameter of the rising air flow forming body 20 that decreases in the height direction, so that the outer diameter dimensions of the lower and upper ends of the spiral wing 30 are approximated. It is desirable to form.

The generator 120 is a component that generates electricity by receiving rotational force from a rotational shaft, and various generators used in the wind power generation field may be selected and applied without limitation, but while having a rated capacity suitable for the rotational torque of the rotational shaft 40 It is desirable to install a compact structure.

For example, in the generator 120, when the drag of the spiral blades 30 is transmitted to the rising airflow forming body 20 and the rotation shaft 40 is rotated, the motor shaft connected to the rotation shaft rotates, and the built-in power generation coil or permanent magnet rotates.

When wind blows in a state in which the rotation shaft 40 as shown in Figs. 1 and 2 is connected to the motor shaft of the generator installed on the support plate 100, drag is applied to the spiral blades 30, and general wind power generation Similar to the rotating body, the rotational operation is performed, and electric energy is generated by the power generation action of the generator 120 connected to the rotational shaft 40.

In particular, in the fluid generator according to the first embodiment of the present invention, when the wind blows, the upward airflow forming body 20 has a conical shape whose lower outer diameter is larger than the upper outer diameter. Instead of passing all of the wind in a straight line, a certain portion of the air volume creates an upward airflow that moves toward the small diameter upper part.

Such ascending airflow generates rotational force by applying drag to the spiral blades 30. At this time, the spiral blades 30 have a structure wound in a spiral shape as the width in the horizontal direction gradually increases from the bottom to the top. It has the advantage of increasing power generation efficiency because the rotation torque is increased by receiving additional drag caused by the rising air flow while performing the function of maintaining the rising air current by confining it to some extent.

In particular, the first auxiliary drag blade 50 is formed such that the width in the horizontal direction gradually increases from the bottom to the top so as to effectively confine the wind. Here, the horizontal width refers to the distance from the portion connected to the spiral blade 30 to the outer edge of the first auxiliary drag blade.

Further, the first auxiliary drag blade 50 may be formed integrally with the spiral blade 30, or may be separately manufactured and bonded to the spiral blade 30 by welding or an adhesive.

The second auxiliary drag blade 60 is further configured to form a rotational torque using the drag of the.

The second auxiliary drag wing 60 is formed on the upper end of the spiral wing, and is formed to be bent in a direction receiving drag by an ascending air current.

For example, the second auxiliary drag blade 60 is connected between the upper end of the spiral blade 30 and the upper end of the rising airflow forming body 20, and the cross-sectional shape is curved in an approximately arc shape.

As it is formed, the power generation efficiency can be further improved.

More specifically, since the first auxiliary drag blade 50 is formed at the outer end of the spiral blade 30, the drag is applied while performing the action of trapping the ascending airflow to escape in the direction of the centrifugal force. As is increased, power generation efficiency increases.

And the second auxiliary drag wing (60) is bent in the direction of receiving the drag force by the rising air flow at the upper end of the spiral wing (30), through the valley between the first auxiliary drag wing (50) and the rising air flow forming body (20) Since the rotation torque is increased by applying the drag of the rising air flowing out to the outside, there is an advantage in that the power generation efficiency is additionally increased.

As described above, since rotational torque is additionally formed in the first and second auxiliary drag blades 50 and 60, it is possible to relatively increase the amount of electric energy generated even when a predetermined wind power is used. There is an advantage.
