Description

  The present invention relates to a power generation device, and more particularly to a power generation device configured to generate power by raising and lowering the float body by filling and discharging air in the float body in a water tank.

  Recently, conservation of the global environment has been taken up as an important issue all over the world. In power generation facilities, this problem is not unrelated. Generally, power generation facilities are large in scale, and many substances that cause pollution are generated.

For example, the problem of natural destruction by hydroelectric power generation, the problem of CO2 generation by thermal power generation, the problem of radiation leakage by nuclear power generation, etc. cause serious social problems.
That is, in hydroelectric power generation, large-scale dams for stopping water have been built, and power generation has been ensured at the expense of natural destruction.

As a result, it has recently become difficult to destroy nature and build hydroelectric dams.
Similarly, thermal power generation causes various problems such as the problem of CO2 generation due to combustion of a large amount of oil, etc., and nuclear power generation causes problems such as aging of facilities or radiation leakage generated due to facility management errors, etc. In the future, it will be difficult to expand or maintain these facilities, such as the occurrence of a situation where the number of facilities must be reduced.

On the other hand, recently, power generation facilities that do not adversely affect the global environment using natural energy, such as solar power generation, wind power generation, geothermal power generation, and tidal power generation, have begun to spread. (For example, see Patent Documents 1, 2, and 3)

Formed on the inner periphery of the spur gear 40, When 41 is rotated counterclockwise, the rotating body 44, 44 ... it is formed so as not to rotate the flat gear 40 idles without being pressed.

  Accordingly, when the pulleys 8 and 41 are rotated counterclockwise by the wire rope 6, as shown in FIG. 5A, the spur gear 37 is rotated counterclockwise by the pulley 8, and the generator 5 rotation shaft 7 is rotated clockwise. On the other hand, since the rotation is not transmitted to the spur gear 40 by the pulley 41, the spur gear 40 is rotated clockwise by the spur gear 37.

  On the other hand, when the pulleys 8 and 41 are rotated clockwise by the wire rope 6 as shown in FIG. 5B, the spur gear 40 is rotated clockwise by the pulley 41, while the pulley 8 Therefore, the spur gear 37 is not transmitted to the spur gear 37, so that the spur gear 37 is rotated counterclockwise by the spur gear 40, and the rotating shaft 7 of the generator 5 is rotated counterclockwise.

  Thus, the operation of the entire power generation apparatus 1 will be described. When the left float body 3 shown in FIG. 1 descends and reaches the bottom of the water tank 2, the coupler 20 of the float body 3 moves to the air filling section 9. , The valve in the air filling unit 9 is opened, and the air in the compressed air tanks 11, 11... Is injected into the rubber tube 18 of the float body 3. Then, when air of a predetermined pressure enters the rubber tube 18 and the rubber tube 18 expands to form the protrusions 18a and 18a on the rubber tube 18, the protrusions 18a and 18a are separated from the coupler. The levers 22 and 22 are pushed to separate the coupler 20 from the air filling unit 9, and the valve body of the coupler 20 and the valve body of the air filling unit 9 are automatically closed, and the float body 3 is injected. Ascended by the buoyancy caused by the air, it is guided by the guide columns 15, 15.

  At this time, the wire rope 6 is pulled by the buoyancy of the float body 3, and the pulleys 8 and 41 of the generator 5 are rotated counterclockwise via the pulleys 4, 4,. It rotates counterclockwise to generate electricity, and at the same time pulls the right float body 3 downward to lower the float body 3.

  When the float body 3 on the left side rises and reaches the upper part of the water tank 2 and the lid body 36 is pushed downward by the lid push plate 28, the air in the rubber tube 18 of the float body 3 is released. Thus, the buoyancy of the float body 3 is reduced.

  When the left float body 3 reaches the top of the water tank 2, the right float body 3 reaches the bottom of the water tank 2, and the coupler 20 of the float body 3 is fitted into the air filling section 9. Is filled with air.

  Then, when the right float body 3 is sufficiently filled with air, the coupler 20 is separated from the air filling portion 9, and when the float body 3 starts to rise, the left float body 3 is pulled and lowered, At the same time, the pulleys 8 and 41 are rotated clockwise by the wire rope 6, the spur gear 40 is rotated by the pulley 41, and the rotation of the spur gear 40 is transmitted to the spur gear 37 and the rotary shaft 7. The generator 5 is rotated counterclockwise by the rotation of the rotating shaft 7 to generate power.

Similarly, the left and right float bodies 3 continue to rise and fall alternately, and the same operation is continued until the compressed air tanks 11, 11,.
The operation stops when the compression tanks 11, 11,... Decrease to a predetermined pressure, but when air is supplied to the compression tanks 11, 11,.

  Thus, when the float body 3 is filled with air, the power generating apparatus 1 moves up in the water tank 2 and lowers the other float body 3 via the wire rope 6, and The generator 5 can be rotated by rotating the rotary shaft 7 of the generator 5, and a simple configuration, a low power generation cost, and a pollution-free power generator can be obtained. In addition, since the power generation device 1 is pollution-free and noise-free, it can be installed in a city center by renewing or remodeling an existing building, and a power transmission device that requires a large amount of cost can be simplified. Furthermore, since the buoyancy of still water and air is used, the running cost can be minimized. And the power generation cost can be further reduced by using midnight power.

  Further, since the float body 3 includes the rubber tube 18 which is an airtight bag body, the rubber tube 18 can be filled with air and discharged, and the float body 3 is floated. Ascent and descent of the float body 3 can be facilitated.

  Further, since the rubber body 18 is housed in the cage frame 17 of the float body 3, the rubber tube 18 is stably held and the weight of the float body 3 can be adjusted by the cage frame 17. Become.

  Furthermore, since the float body 3 is guided by guide pillars 15 arranged in the vertical direction in the water tank 2, the float body 3 is lifted and lowered in a predetermined direction within a predetermined range. However, there is no possibility of contacting the other float body 3 or the wall surface of the water tank 2.

  The float body 3 is provided with rollers 16, 16... For rolling the side surfaces of the guide columns 15, 15..., So that the float body 3 can smoothly move along the side surfaces of the guide columns 15, 15. Guided.

  Further, since the generator 5 is connected to the one-way clutch 42 for left rotation and the one-way clutch 43 for right rotation, the generator 5 is always rotated in the same direction even if the operating direction of the wire rope 6 is changed. Power generation efficiency.

Further, since the compressed air tank 11 is connected to the air filling unit 9, the float body 3 can be filled with the compressed air by the compressed air tank 11.
Furthermore, since the compressor 14 is connected to the compressed air tank 11, the compressed air can be refilled in the compressed air tank 11 by the compressor 14.

  In addition, a coupler separating lever 22 is disposed in the air filling unit 9, and the coupler separating lever 22 is configured to separate the coupler 20 from the air filling unit 9. When a predetermined pressure is reached, the coupler 20 and the air filling unit 9 can be automatically separated.

  Further, the air discharge means 19 is configured such that the cover 36 is pressed against a seal 34 fixed in the vicinity of the outer peripheral portion of the air discharge port 33 to restrict air discharge, and the cover 36 is pressed when the cover 36 is pressed. Since the air is discharged away from the seal 34, the air can be easily discharged by the lid pressing plate 28 pressing the lid 36.

  FIG. 10 shows an air discharge means 47 of another embodiment that can be used in place of the air discharge means 19, and the air discharge means 47 has an air outlet 29 opened at the upper center portion of the cage frame 17. An opening 30 is opened in the upper part of the rubber tube 18 corresponding to the air outlet 29, and a standing portion is provided at the opening edge of the opening 30 over the entire circumference of the opening edge. 31 is formed, and the standing portion 31 is closely fitted to the air outlet 29.

  Further, the air outlet 29 is encapsulated in a hermetic state by a circular container-like lid guide 48, and an air exhaust port 49 is opened at the upper portion of the lid guide 48, and at the lower portion of the air exhaust port 49. A plurality of radially cut air passages 50.50... Are formed.

  An annular seal 51 is fixed to the lower surface of the upper portion of the lid guide 48 and in the vicinity of the outside of the air discharge port 49, and has a diameter larger than the seal 51 below the seal 51. A dome-shaped flexible lid 52 that is in pressure contact with the seal 51 and blocks the flow of air is disposed. The flexible lid 52 is held by appropriate means so as to maintain the normally closed state.

  Thus, as shown in FIG. 5B, when the rubber tube 18 is filled with air and the air discharge means 47 is present in the water, the flexible lid 52 is placed in the rubber tube 18. Due to the balance between the air pressure and the hydraulic pressure from above the flexible lid 52, the flexible lid 52 is in pressure contact with the seal 51 and closed, and the discharge of air in the rubber tube 18 is restricted. ing.

  Then, as shown in FIG. 5C, when the air discharging means 47 rises above the water surface in a state where the rubber tube 18 is filled with air, the flexible lid 52 is moved to the air pressure inside the rubber tube 18. And the atmospheric pressure from above the flexible lid 52 is deformed so that the central portion of the flexible lid 52 protrudes upward, and the flexible lid 52 is the seal 51. The air is deformed so as to be separated from the lower end of the air discharge port 49, whereby the air in the rubber tube 18 is discharged through the air passage 50. When the air pressure in the rubber tube 18 becomes equal to or lower than a predetermined pressure, the flexible lid 52 is restored to the original shape, and the seal 51 is pressed to return to the closed state.

  FIG. 11 shows an air discharge means 53 that can be provided in place of the air discharge portion 10 and the air discharge means 19. The float 54 is composed of a spherical float 54 a and a lever 54 b extending from the float 54 a, and the operation of the float 54.

  Thus, when the air discharge means 53 is positioned in the water tank 2, the float 54a of the float 53 is positioned upward by buoyancy to close the valve 55, and the float 54a arrives at the water surface and reaches the water surface. When the float 54 inclines in a lying state, the valve 55 is opened, and the air in the rubber tube 18 is discharged.

Thus, the air discharge device 53 can obtain substantially the same effect as the air discharge unit 10 and the air discharge means 19.
FIG. 12 shows a power generation device 56 according to another embodiment. The power generation device 56 is provided with three power generation devices 57, 58, and 59 that are substantially the same as the power generation device (1 in FIG. 1).
