Description

[Technical Field]

[0001] This invention relates to a power generating device that utilizes gravity and buoyancy. [Background technology]

[0002] Power is the energy used to operate machines and the like, and includes hydraulic power, wind power, electricity, human power, thermal power, and atomic power. Machines and the like operate using energy input from outside or convert it into other forms of energy. For example, automobiles burn gasoline to obtain rotational power for their engines, converting chemical energy into mechanical energy. However, since the gases emitted can have effects such as air pollution and global warming, there is a demand for clean energy that places less strain on the environment. As described in Patent Document 1, an invention has been disclosed for a power system that uses buoyancy as a clean energy source. [Prior art documents] [Patent documents]

[0007] In the power generating device, a belt is looped around an upper roller provided at the upper end of the sliding plate and a lower roller provided at the lower end, and the packing is placed on the belt and lowered.

[0012] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. Note that parts having the same functions are designated by the same reference numerals, and repeated description thereof may be omitted. [Example]

[0013] First, the power generating device of the present invention will be described. Figure 1 is a diagram illustrating an outline of the power generating device.

[0014] As shown in FIG. 1, the power generating device 100 attaches the float 200 to the packing 300 and moves it down 120 through the liquid 110 along the sliding plate 400, and then separates the float 200 from the packing 300 and moves it up 130 from the liquid 110, thereby obtaining the buoyancy of the float 200 as power.

[0015] The float 200 is a hollow, sealed container made of resin or the like, and has a specific gravity lower than that of the liquid 110. When the float 200 is in the liquid 110, its buoyancy exceeds gravity, causing it to rise. The liquid 110 is water or the like.

[0016] Packing 300 is made of a material such as a rubber plate having a higher specific gravity than liquid 110, and when in liquid 110, its buoyancy becomes less than gravity and it descends. When float 200 is placed on packing 300, the float 200 and packing 300 are tightly fitted together so that liquid 110 does not enter the gap between them, allowing float 200 to sink together with packing 300 in liquid 110.

[0017] The sliding plate 400 is a plate material that is placed at an angle in the liquid 110. When the packing 300 is placed on the sliding plate 400, if there is no friction between the sliding plate 400 and the packing 300, the packing 300 will slide down along the sliding plate 400.

[0018] When the packing 300 is peeled off from the float 200 that has descended 120, the float 200 pushes aside the liquid 110 due to buoyancy and rises 130. The float 200 that has risen can be returned to its original position and recovered 140.

[0019] 2 and 3 are diagrams illustrating the operation of the power generating device. As shown in Fig. 2(a), first, an upper roller 600 is provided on the upper end of the sliding plate 400, and a lower roller 610 is provided on the lower end of the sliding plate 400, and a belt 500 is looped around the upper roller 600 and the lower roller 610. The belt 500 is in contact with the upper and lower surfaces of the sliding plate 400.

[0020] The upper roller 600 can rotate around an axis at its center, and the lower roller 610 can also rotate around an axis at its center. The belt 500 can be sent out like a conveyor by rotating the upper roller 600 and the lower roller 610.

[0021] At the upper end of the sliding plate 400 in the liquid 110, the float 200 is placed 150 in close contact with the packing 300, and the packing 300 is then placed on the belt 500. It is sufficient that the packing 300 and the belt 500 are engaged to prevent slippage.

[0022] As shown in FIG. 2(b), if the specific gravity of the float 200 and the packing 300 in the liquid 110 is greater than that of the liquid 110 and they have enough weight to push the belt 500 forward, the float 200 and the packing 300 will descend 120 along the sliding plate 400.

[0023] Even if the specific gravity of the float 200 and the packing 300 is smaller than that of the liquid 110, it is possible to make the float 200 and the packing 300 descend 120 by generating a force that pushes away the liquid 110 diagonally below.

[0024] As shown in FIG. 3(a), when the float 200 is separated 160 from the packing 300 at the lower end of the sliding plate 400, the float 200 pushes aside the liquid 110 by its buoyancy and rises 130.

[0025] As shown in Figure 3(b), the rising float 200 is retrieved 140 to the top of the sliding plate 400 and then placed back onto the belt 500. This process is repeated. In this process, the buoyancy generated when the float 200 rises 130 is used as power.

[0026] If the specific gravity of the float 200 and the packing 300 is smaller than that of the liquid 110, the float 200 remains in close contact with the packing 300, and the packing 300 is peeled off from the sliding plate 400, causing the float 200 and the packing 300 to rise 130 due to buoyancy.

[0027] Figures 4 and 5 are diagrams illustrating the operation of a power generator when an atmospheric pressure chamber is provided on the sliding plate, and Figure 6 is a diagram illustrating the shape of the atmospheric pressure chamber provided on the sliding plate of the power generator.

[0028] First, as shown in Figure 4(a), a part of the top surface of the sliding plate 400 is cut out to provide an atmospheric pressure chamber 410. The atmospheric pressure chamber 410 is connected to the outside by an air vent 420 and is filled with air at atmospheric pressure. The space on the top surface of the atmospheric pressure chamber 410 is blocked with a belt 500 to prevent air from leaking into the liquid 110 as much as possible.

[0029] In order to attach packing 300 carrying float 200 to belt 500, protrusion 310 is provided on packing 300 and fitting hole 510 is formed in belt 500. When belt 500 rotates and fitting hole 510 reaches the upper end of sliding plate 400, packing 300 is placed 150 on belt 500 and protrusion 310 is fitted into fitting hole 510.

[0030] 4(b), when belt 500 rotates and fitting hole 510 comes above atmospheric pressure chamber 410, fitting hole 510 is blocked by protrusion 310, preventing air from leaking. The pressure of liquid 110 presses float 200 and belt 500 against sliding plate 400 with pressure 170, and the force of liquid 110 moving toward atmospheric pressure chamber 410 causes atmospheric pressure chamber 410 to be blocked by belt 500.

[0031] As shown in FIG. 5(c), when the mass of the float 200 and the packing 300 is heavier than the same volume of liquid 110, the float 200 and the packing 300 descend 120 along the sliding plate 400, and the belt 500 rotates.

[0032] As shown in FIG. 5( d ), when the rotation of the belt 500 causes the fitting hole 510 to pass above the atmospheric pressure chamber 410 and the float 200 to reach the lower end of the sliding plate 400 , the protrusion 310 is peeled off 160 from the fitting hole 510 .

[0033] When the mass of the float 200 and packing 300 is lighter than the liquid 110 of the same volume, the pressure of the liquid 110 causes the float 200 and packing 300 to descend 120 along the sliding plate 400. When the float 200 reaches the lower end of the sliding plate 400 and peels 160 the protrusion 310 from the fitting hole 510, the float 200 rises 130 due to buoyancy.

[0034] 6(a), an atmospheric pressure chamber 410 formed on the upper surface of the sliding plate 400 is covered by a belt 500 that is wound in a circular shape from an upper roller 600 arranged at the upper end of the sliding plate 400 to a lower roller 610 arranged at the lower end of the sliding plate 400. The fitting holes 510 formed in the belt 500 move along and above the atmospheric pressure chamber 410 as the belt 500 rotates.

[0035] As shown in Figure 6(b), an atmospheric pressure chamber 410 may be formed with a plurality of through holes 430 on the upper surface of the sliding plate 400. The atmospheric pressure chamber 410 may be reduced in pressure below atmospheric pressure. Even if the fitting holes 510 are not formed in the belt 500, the packing 300 may be made to be able to be adsorbed by pressure or the like.

[0036] Fig. 7 is a diagram illustrating a means for recovering the float of the power generating device. Fig. 8 is a diagram illustrating the circulation of the float of the power generating device. As shown in Fig. 7(a), in the power generating device 100, the float 200 that has reached the lower end of the sliding plate 400 is moved to the upper end of the sliding plate 400.

[0037] An upper rotor 700 is provided which rotates in synchronization 750 with the upper roller 600. A lower rotor 710 corresponding to the lower roller 610 is also provided, and a chain 720 is looped from the upper rotor 700 to the lower rotor 710.

[0038] The chain 720 is provided with a connecting portion 740 to which the float 200 is attached, and also with a guide rail 730 for guiding the float 200 to descend 120 from the upper end to the lower end of the sliding plate 400 and then ascend 130 from the lower end to the upper end of the sliding plate 400.

[0039] The upper rotor 700 also has a means for placing 150 the float 200 on the belt 500 at the upper end of the sliding plate 400, and the lower rotor 710 also has a means for peeling 160 the float 200 from the belt 500 at the lower end of the sliding plate 400.

[0040] As shown in FIG. 7(b), the float 200 descends 120 along the sliding plate 400 due to gravity, and is then raised 130 by buoyancy and recovered 140 to its original position, thereby making it possible to repeatedly obtain power from buoyancy.

[0041] As shown in Figure 8(a), for example, if three connecting parts 740 are provided at equal intervals on a chain 720 looping along a guide rail 730 and floats 200, 200a, and 200b are attached to each of them, the buoyancy of floats 200 and 200a can be used to apply a force to lower float 200b.

[0042] Note that the atmospheric pressure chamber 410 may be replaced by a reduced pressure liquid chamber 410a filled with a viscous liquid or a liquid with a lower pressure than the surrounding liquid 110, instead of air, to reduce friction and prevent the packing 300 from peeling off from the belt 500. The reduced pressure chamber 410a may be connected to a tank 440 and the pressure may be adjusted by adjusting the height of the water surface.

[0043] As shown in FIG. 8(b), the through holes 430 formed in the sliding plate 400 may also be formed as vertical grooves 430a extending in the longitudinal direction so as to follow the movement of the belt 500.

[0044] Fig. 9 is a diagram illustrating a mounting means for the float of the power generating device, Fig. 10 is a diagram illustrating a detachment means for the float of the power generating device, and Fig. 11 is a diagram illustrating a connecting portion of the float of the power generating device.

[0045] As shown in Figure 9(a), the float 200 is attached to a chain 720 hanging from an upper rotating body 700 by a connecting part 740, and rises 130 by buoyancy along the upper rail of a guide rail 730 to the upper end of the sliding plate 400.

[0046] 9(b), the upper roller 600 and the upper rotating body 700 rotate synchronously 750 using gears or the like, and the protrusion 310 is placed 150 by, for example, pressing the packing 300 into the fitting hole 510 of the belt 500 that is wrapped around the upper roller 600. Alternatively, the float 200 and the packing 300 may be brought into close contact with each other first.

[0047] 10, float 200 is attached to belt 500 and descends 120 along the lower rail of guide rail 730 to the lower end of slide plate 400. Float 200 is peeled off 160 by creating a gap between it and packing 300. The same procedure can be used to remove packing 300 from belt 500.

[0048] 11, a connecting portion 740 may be provided on the side of the float 200, and the float 200 may be attached using the shaft that connects the chains 720 together. If the chains 720 are stretched over the guide rails 730, the float 200 will move along the guide rails 730.

[0049] According to this invention, power can be generated by utilizing gravity and buoyancy as clean energy.

[0050] Although the embodiments of the present invention have been described above, the present invention is not limited to these. [Explanation of symbols]
