Abstract

PURPOSE:To take out power by a simple method by supplying a buoyant body in a vessel containing liquid and by making a moving member move upward on account of buoyancy of the buoyant body. CONSTITUTION:In a water tank 1, since the specific gravity of a buoyant body 2 is smaller than that of water, buoyancy, which is obtained as the product of the underwater volume of the buoyant body 2 by the density of water, acts on the buoyant body 2. Accordingly, the buoyant body 2 moves upward, pushing a rack 24 upward along the vertical direction of the tank 1. Rising movement of the rack 24 rotates No.1 and No.2 gears 25 and 26 which are engaged with the rack 24. And the power in the form of revolving force can easily be taken out of No.1 and No.2 output shafts 22 and 23.

Description

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

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

There are thermal power generation, nuclear power generation, solar power generation, wind power generation, wave power generation, etc. Hydroelectric power generation is limited in its 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. Furthermore, solar power generation, which has become popular in recent years, is expensive in terms of equipment costs, and wind power and wave power generation have the disadvantage that the power generation time is dependent on nature.

The operation of the buoyancy type power generator 9 configured as shown below will be explained. First, before starting this buoyancy type power generator, one end of the second output shaft 2 ((provided)
- Operate the handle 28b to apply external force to the buoyancy type power generation device. Since a clutch 28 is provided between the second output shaft 2 and the handle 28h, the clutch 28 is first connected, and then the handle 285'ff is connected to the handle 28h.
4. Rotate in the direction that it rises. By performing the above operations,
The rotation of the spindle 28b is transmitted to the second output example 26 via the clutch 28. to the second output shaft 26 (is the first
The tin rocket 27 is stuck 1. As a result, this first sphere 27 rotates. The rotation of the first sprocket 27 is supplied via the first chain roller 4, and is transmitted to the gear 61 (speed reducer 61) at the sliding part roller 0π.
The rotation is input to the second sprocket (second sprocket fixed to the input shaft) 31CL, and a rotational output obtained by decelerating fL to a predetermined value is obtained from the third sprocket 315. Incidentally, the reduction ratio of the reducer 610 is such that for every stroke of movement of the rack 24 that meshes with the second gear 26, the press rod roller 6 in the supply 5 drive section QK moves one stroke. It has the ability to be set up. The rotation of the lower sprocket filter 1b is transmitted to the fourth sprocket 37a of the pantograph 62 via the second chain filter 8a. At this time, the loss of transmission force is reduced by the action of the tension lever filter 8a. 4th sprocket): When the bolt loop 7 rotates with the rotation of the bolt 67a, the bolt loop 67 has reverse threads on both ends. Move closer to each other.

Then, the pantograph 62 is displaced to extend, and the press rod 63 provided at the connecting part facing the fixing part 65 moves toward the supply part 10, completely passes through the hole 11 of the supply part 10, and inserts it into the buoyant body 2. Press. At this time, a stopper 14 provided in the supply section 10 in the middle of the supply yarn path of the buoyant bodies 2 rises with the movement of the press rod rollers, and one of the buoyant bodies 2 is moved to the notch 5.
It is designed so that it does not become an obstacle when extruding it into the aquarium 1 through. Also, in synchronization with the movement of the pressure rod roller, a stopper 6 provided at the bottom of the water tank 1 projects into the water tank 1, is set above the floating body 2, and is supplied from the n1 notch 5 f'1.
It is designed to temporarily prevent the buoyant body 2 from rising upward. When the above situation is reached, No Ndol 2
When the rotation of 8b is stopped, the large 24 descends due to its own weight and is set at the bottom dead center. At this time, just before the rack 24 reaches the bottom dead center, the stopper 6 returns to its original position 9, and the roller 29 (ZK buoyant body 2) at the lower end of the rack 24 is held and pulled. With the lowering of 24, the gear of the first tJ2 rotates in the opposite direction to the rotation f' imparted by the steering wheel 28/). At this time, the first output shaft 22 is prevented from rotating by the action of a one-way latch.

On the other hand, the second output shaft 26 to which the second gear 26 is fixed is
Rotation in the opposite direction to that at startup is transmitted. This rotation is
In the same manner as above, the speed reducer 61. It is transmitted to the pantograph 32. The fourth sprocket of pantograph Fro 2 is
Since the rotation is in the opposite direction to that at the time of starting, the nut portion 36a is rotated by the rotation of the bolt roller 7.

66h move away from each other. Therefore, the tip of the suppressor filter 6 is pulled back from the supply section 10 by 1%.

It will be in a standby state in order to press the next buoyant body 2.

In the aquarium 1, the buoyant body 2 thrown 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 is in the vertical direction vc j3 of the water tank 1.
It rises while pushing up the rack 24. At this time, the weight of the rank 240 and the frictional force between the rack 24 and the first and second gears acting as a drag force against the buoyancy force, it is desirable to reduce this drag force as much as possible. In this embodiment, a boosting mechanism is adopted for the supply and drive unit filter 0,
This is a means of reducing drag. The upward movement of the rack 24 causes the first. The second gear 25,26 is rotated, and the first gear 25,26 is rotated. Power as rotational force can be extracted from the second output shafts 22, 2. This rotation continues until the rack 24 reaches the top dead center, that is, until the buoyant body 2 reaches the liquid level of 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 1a 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, is guided by a guide member 13 provided at the edge of the water tank 1, and falls naturally. When the buoyant book 2 is removed from the rack 24, the rotation of the roller 29a allows the buoyant body 2 to move smoothly. On the other hand, the rotation of the second gear 26, which rotates as the rack 24 moves upward, is caused by the rotation of the first sprocket l-27. first chain 6
4 to the Ail reduction gear 31). This rotation is in the same direction as the manual rotation for starting described above. The rotational force inputted to the reducer 61Vc acts as an anchor as described above, and is transmitted to the fourth sprocket 37a of the pantograph 32 at a reduced speed. Since the fourth sprocket 37a rotates in the same direction as when starting, the nut section 6+2. The filters 6h are moved closer to each other. Therefore, the tip of the pressing rod 63 is
It moves to the supply section 10 side, passes through the hole 11 of the supply section 10, and suppresses 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 rack 24 and the toothed first gear 2
5 rotates, but this rotational force is not transmitted to the first output shaft 22 due to the action of the one-sided clutch (not shown) as described above. Therefore, the first output shaft 22 (/) can only rotate in the same direction.
4 and the second gear 26 rotate in the same rotational direction as at the time of startup. Therefore, in the supply drive unit 60, the press rod roller is moved to the supply unit 10 side, and the next buoyant force is body 2
[operates] to supply water into the aquarium 1. The buoyant body 2, which is guided by the guide member 13KG that pops out from the liquid surface, is guided to the buoyant body input port 12 in the supply 1B10tc, and when the press rod 66 is pulled back from the supply section 10, it is introduced into the supply system. The water is supplied into the aquarium 1 again. Due to the above action, as the buoyant body 2 rises, that is, the rack 24 rises, the next buoyant body 2 is supplied into the water tank 1. 22, it is possible to generate a force of 9 salt.

As explained above, the power obtained by the upward movement of the buoyancy body 2 based on the buoyancy force is greater than the power that supplies the buoyancy body 2, so the second output shaft 22 drives a generator, etc. Power can be extracted 1-.

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

For this reason, several devices t are provided in parallel with the first output shaft 22 in common, and the buoyancy body 2 is provided as a feeder fL so that when the rack 24 is lowered, the rack 24 of another device is raised.
A smooth rotating output can be obtained as the first output m22. Also, several devices can be placed in parallel with each other. For example, the driving of the supply section 10 can be supplemented with another device. Therefore, the supply timing of the buoyant body 2 can be set when the rack 24 approaches the bottom dead center, and the stopper 6 that controls the entire rise of the buoyant body 2 can be removed. In addition, the buoyancy transmitting member that moves with the upward movement of the buoyant body 2 is not limited to the rack 24 that rotates the gear, for example, one end of the swinging link is used as the buoyant force transmitting member, and the vertical movement of the buoyant force transmitting member is The link may be swung according to the 2'LK, and the flywheel or the like may be rotated to extract power.

Furthermore, the shape of the buoyant body 2 (is not limited to a cylinder, but may be of various other shapes such as a rectangular parallelepiped. Also, the buoyancy body 2 is not limited to a cylinder but may have various other shapes such as a rectangular parallelepiped. Also, the buoyancy body 2 is an example of a boosting mechanism. You can also use various other means,
The power from the power generation section 20 does not necessarily need 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 generation section 20 is as follows.
It can produce more energy than the supplied power. It should be noted that this buoyancy type power generation device can be implemented using other liquids other than wood, and if it is implemented using seawater, for example, the scope of its use will be extremely wide. . In other words, if a guide is provided in the seawater to fully regulate the ascending path of the buoyant bodies 2, and the buoyant bodies 2 are sequentially supplied into this guide to extract power based on the buoyancy, it can be used for underwater power generation, etc. . Also, since it has a large buoyancy in seawater, it can be said to be extremely effective in its use.

As explained 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. can.
