Abstract

PURPOSE:To provide additional effective power source, by converting upward movement of a floating body in liquid to power. CONSTITUTION:A clutch 28 is engaged, and then a handle 28b is rotated in such a direction as to raise a rack 24. Rotation of a first sprocket 27 is transmitted through a first chain 34 to a reduction gear 31 in a supply drive portion 30. When a bolt 37 is rotated together with rotation of a fourth sprocket 37a, nut members are moved so as to approach to each other. At this time, a pantagraph 32 is displaced so as to be expanded, and thereby to move a push bar 33 provided at a connection portion opposed to a fixed portion 35 to a supply section 10 side, the push bar 33 being inserted into a hole 11 of the supply section 10 to push a floating body 2. In such a circumstance as above, when the rotation of the handle 28b is stopped, the rack 24 falls owing to its tare, and is positioned at a bottom dead center to retain the floating body 2 by a roller at a lower end of the rack 24. Buoyancy is acted on the floating body 2 in the water. Accordingly, the floating body 2 rises along a vertical direction of a water bath 1, while raising the rack 24.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a buoyancy type power generation device that generates power by utilizing buoyancy acting on an object in water.

Hydroelectric power generation is currently being used as a power generation method.

There are thermal power generation, solar power generation, wind power generation, wave power generation, etc. Hydroelectric power generation has limited installation locations and leads to the destruction of nature. Thermal power generation consumes large amounts of limited petroleum resources, and the dangers of nuclear power generation have become a social issue.

is attached to the bottom surface of the pressing rod 63.

The operation of the buoyancy type power generator 9 configured as described above will be explained. First, to start the buoyant power generator, the handle 28h provided at one end of the second output shaft 26 is operated to apply external force to the buoyant power generator. Since a clutch 28 is provided between the second output shaft 26 and the handle 28h, the clutch 28 is connected first, and then the handle 28b is rotated in the direction in which the rack 24 is raised. Through the above operation, the rotation of the handle 28h is transmitted to the second output shaft 23 via the clutch 28. Since the first sprocket 27 is fixed to the second output shaft 23, the first sprocket 27 rotates. The rotation of the first sprocket 27 is transmitted to the speed reducer 31 in the supply drive section 30 via the first chain 34. The speed reducer 61 inputs the rotation to a second sprocket 61α fixed to the input shaft, and obtains a rotational output resulting from a predetermined deceleration of the sprocket to a third sprocket 311J.

Note that the reduction ratio of the reducer 31 is set such that the press rod 66 in the supply drive unit 30 moves one stroke for one stroke movement of the rack 24 that meshes with the second gear 26. It's being carried away. Said third sprocket 31
6 is transmitted to the fourth sprocket 67α in the pantograph 32 via the second chain 38cL. At this time, the loss of transmission force is reduced by the action of the tension lever 38α. Fourth tin rocket 67α
When the bolt 67 rotates together with the rotation of the bolt 37, the nut portions 36α and 36b, which mesh with threaded portions having outward screws formed on both ends of the bolt 37, move closer to each other. Then, the pantograph 32 is displaced so as to extend, and the press rod 6 provided at the connecting part facing the fixed part 65
6 moves to the supply section 10 side, passes through the hole 11 of the supply section 10, and suppresses the buoyancy body 2fc. At this time, supply section 1oVC
A stopper 14 provided in the middle of the supply yarn path of the buoyant bodies 2 rises as the pressing rod 63 moves, and one of the buoyant bodies 2 is pushed out into the water tank 1 through the notch 5''f. In addition, in synchronization with the movement of the press rod 63, a stopper 6 provided at the bottom of the water tank 1 protrudes into the water tank 1 and is set above the floating body 2. It is designed to temporarily prevent the floating body 2 supplied from the floating body 2 from rising.When the above condition occurs, if the rotation of the nozzle 28h is stopped, the large 24 will descend due to its own weight. , is set at the bottom dead center. At this time, the stopper 6 returns to its original position just before the rack 24 reaches the bottom dead center, and eventually
The buoyant body 2 is held by the roller 29α at the lower end of the rack 24. Incidentally, as the rack 24 descends, the gears it and i2 rotate in the opposite direction to the rotation given by the knob 28hK. At this time, the first output shaft 22 is prevented from rotating by the action of the one-way latch.

- Gear 26'r of Manbou 2: The fixed second output shaft 26 transmits rotation in the opposite direction to that at the time of starting. This rotation is
In the same manner as above, the speed reducer 61. The information is transmitted to the pantograph 32. The fourth tin rocket of Pantograph 32 is
In order to rotate in the opposite direction to that at startup, the nut portion 36α is rotated by 370 turns of the bolt.

36A will move away from each other l) K will move. Therefore.

The tip of the suppressor 33 is pulled back from the supply unit 10 and is in a standby state for suppressing the n1-order buoyant body 2.

In the aquarium 1, the buoyant body 2 put into the water has a smaller specific gravity than the water, so the product of the volume occupied by the buoyant body 2 in the water and the specific gravity of the buoyant body 2 is the buoyant force. It acts on the buoyant body 2.

Therefore, the buoyant body 2 rises along the vertical direction of the water tank 1 while pushing up the rack 24. At this time, since the weight of the rack 24 and the frictional force between the first and second gears meshing with the rack 24 act as a drag force against the buoyancy, it is desirable to reduce this drag force as much as possible. In this embodiment, a booster mechanism is employed in the supply drive unit 3° as a means of reducing drag. The upward movement of the rack 24
The first one meshes with the other. The second gear 25,26 is rotated, and the first gear 25,26 is rotated. Power as rotational force can be suspended from the second output shaft 22,23. This rotation continues until the rack 24 reaches the top dead center, that is, until the buoyant body 2 reaches the liquid level in the water tank 1. The buoyant body 2 that has reached the vicinity of the liquid surface is guided by a curved guide 4 at the open end 1α of the water tank 1 and is restricted in a direction outward from the vertical direction. Then, the buoyant body 2 jumps out from the liquid surface while following the curved guide 4, and naturally falls while being guided by a guide member 16 provided in the 10th grade section of the tank. When the buoyancy body 2 is removed from the rack 24, the movement of the rotational force source body 2 of the roller 29α becomes smooth. On the other hand, the rotation of the second gear 260, which rotates as the rack 24 moves upward, causes the first tin rocket 27. It is input to the reduction gear 31 via the first chain 34. This rotation is in the same direction as the manual rotation for starting described above. The rotational force input to the reducer 31 acts in the same manner as described above, and the pantograph 3
The deceleration is transmitted to the fourth sprocket 37α at 21C. Since the fourth tin rocket 37α rotates in the same direction as when starting, the nut portions 36α and 66h move closer to each other. For this reason, the pressure rod 3
The tip of 3 moves to the supply section 10 side, passes through the hole 11 of the supply section 10, and presses the next buoyant body 2. On the other hand, the rack 24 which has reached the top dead center in the water tank 1 due to the detachment of the buoyancy body 2 falls to the bottom of the water tank 1 due to its own weight since no buoyant force acts on it. At this time, the first gear 25 that meshes with the rack 24 rotates, but this rotational force is not transmitted to the first output shaft 22 due to the action of the one-way clutch (not shown) as described above. Therefore, the first output shaft 22 can only rotate in the same direction. Further, the second gear 26 that meshes with the rack 24 rotates along the same rotational direction as when starting. Therefore, supply drive 130Vc
Then, the press rod 63 is moved to the supply section 10 side, and operates to supply the next buoyant body 2 into the water tank 1. The buoyant body 2 that is guided from the liquid surface along the guide member 16 is guided to the buoyant body input port 12 in the supply section 10Vc, and when the pressing rod 33 is pulled back from the supply section 10, the buoyancy body 2 is guided along the guide member 16. When the water is put into the water tank 1, it is fed into the water tank 1 again. Due to the above action, the buoyant body 2 rises, that is, the buoyant body 2
4, the next buoyant body 2 is supplied into the tank 1,
By sequentially repeating this process, power can be extracted from the first output shaft 22.

As explained above, the power obtained by the upward movement of the buoyancy body 2 based on the buoyancy force is larger than the power that supplies the buoyancy body 2, so the power to drive the generator etc. is transmitted from the second output shaft 22. t) Can be hung.

It goes without saying that the present invention is not limited to the above embodiments, but includes various modifications within the scope of the invention. For example, in the embodiment, the first output shaft 22
Since the rotation of the rack 24 does not occur while the rack 24 is being lowered, the rotation is intermittent.

For this reason, several devices are provided in parallel with the first output shaft 22 in common, and when the rack 24 of the other device is lowered, the buoyant body 2 is supplied so that the rack 24 of the other device is raised. A smooth rotational output can be obtained from the output shaft 22 of. or,
By arranging several devices in parallel, the driving of the supply section 10 can be complemented by other devices. Therefore, the supply timing of the buoyancy body 2 can be set when the rack 24 approaches the bottom dead center, and the stopper 6 that restricts the rise of the buoyancy body 2 can be removed. In addition, the buoyancy transmission member that moves with the upward movement of the buoyant body 2 is the rack 2 that rotates the gear.
Not limited to 4, for example, one end of the swinging link is used as a buoyancy transmission member, and the link is swung according to the vertical movement of the buoyancy transmission member,
This may be used to rotate a flywheel or the like to extract power.

Further, the shape of the buoyancy body 2 is not limited to a cylinder, but may be various other shapes such as a rectangular parallelepiped. Further, the pantograph 32 as a means for supplying the buoyancy body 2 is an example of a boosting mechanism, and various other means can be used, and the power from the power generation section 20 does not necessarily have to be used. . for example,
Even if the buoyancy body 2 is supplied into the water tank 1 using the power of another engine, the output obtained by the power generating section 20 can be made to have more energy than the supplied power. It goes without saying that this buoyancy type power generator can be implemented using liquids other than water, and if seawater is used, for example, the scope of its application will be extremely wide. That is, if a guide is provided in seawater to regulate the upward path of the buoyant bodies 2, and the buoyant bodies 2 are sequentially supplied into this guide to generate several motive power based on buoyancy, it can be used for underwater power generation, etc. . In addition, since it has a large buoyancy in seawater, it can be said that the effectiveness of its use is extremely large.

As described above, according to the present invention, it is possible to provide a buoyancy type power generation device that can convert upward movement of a buoyancy body in a liquid into power and use it as another effective power source.
