[Prior art]
Conventionally, energy sources for power generation use hydropower (using rainwater flowing into dams), thermal power (using petroleum, coal, etc. as raw materials) and nuclear power (such as uranium atoms), or buoyancy power generation or geothermal heat using waves. Among them, buoyancy power generation has great potential due to the development of the submarine method of the foundation of the support mechanism due to the development of marine engineering in the future.
As this buoyancy power generation, there is one currently generated by compressing air by up and down motion of a wave and rotating a turbine with compressed air to generate power.
However, this system uses compressed air to rotate the turbine, so the turbine efficiency is poor, and the apparatus is very complicated and has many malfunctions. Yes.
In addition, as a relatively simple mechanism, it is also considered to use a wave using a rack and a pinion, but this method uses only a one-way movement of the wave, The usage efficiency was very bad.
The principle of buoyancy power generation is balanced when a floating body floats on the sea surface, as shown in FIG. 5, with buoyancy = pressure per unit area of p = p ₀ ¢ gh applied to this floating body.
Further and force is applied that buoyancy P × S ₀ to a point in the center of the surface area S ₀ facing the atmosphere of the floating body, the buoyancy PS ₀ is a major force the wider surface area S _0.
The buoyancy PS ₀ generates vertical kinetic energy when the sea surface changes from B to A or from A to B as shown in FIGS. 5 (a) and 5 (b).
That is, when the weight of the floating body 1t is 1 m / sec / sec and the B water surface floats up to the A water surface, a power of 1 Nm = 1 Joule = 1 KWHx efficiency is generated at the center of the floating body.

[0010]
Next, the operation of the wave device using the floating body of the present invention will be described.
As shown on the right side of FIG. 1, for example, when the deck 4 is lowered due to the lowering of the floating body 1, the main lever mounting base 5 and the feed lever mounting portion 12 fixed to the deck 4 are lowered and the slave fixed to the seabed. The main lever pin 11 supported by the support mechanism 10 serves as a fulcrum, the piston rod 8 connected to the main lever 7 by the piston pin 9 rises, and the feed lever pin 14 serves as a fulcrum, and the feed lever 13 feeds the feed lever mandrel pin. 15, the feed lever mandrel 28 is lowered, and the piston rod 8 and the feed lever mandrel 28 are simultaneously raised and lowered in the opposite direction.
Therefore, when the piston rod 8 rises and the feed lever mandrel 28 descends, the feed lever mandrel 28 slides the slider 26 inserted in the slide groove 25 of the fan-shaped slide 24 to the left, so that the merger connected to the slider 26 is combined. The lever 32 is pulled to the left side, the swing link 23 is pulled to the left side, and the main rod 20 connected to the crosshead 17 moves upward while being pulled to the left side. Through 33, the rotational force is output.
[0011]
On the other hand, as shown on the left side of FIG. 1, when the floating body 1 fixed to the deck 4 is raised, the main lever mounting base 5 and the feed lever mounting portion 12 fixed to the deck 4 are lifted to reach the seabed. The main lever pin 11 and the feed lever pin 14 supported by the fixed slave support mechanism 10 serve as fulcrums, the piston rod 8 connected to the main lever 7 by the piston pin 9 is lowered, and the feed lever 13 is fed to the feed lever mandrel. The feed lever mandrel 28 connected by the pin 15 is raised, and the piston rod 8 and the feed lever mandrel 28 are raised and lowered simultaneously in the opposite direction.
Therefore, when the piston rod 8 is lowered and the feed lever mandrel 28 is raised, the feed lever mandrel 28 slides the slider 26 inserted in the slide groove 25 of the fan-shaped slide 24 to the right side. The lever 32 is pushed to the right side, the swing link 23 is pushed to the right side, and the main connecting rod 20 connected to the crosshead 17 descends while being pushed to the right side. Through 33, the rotational force is continuously output.
As shown in FIG. 3, the main lever 7 has a large fluctuation width in the upper and lower portions where the buoyancy applied to the floating body 1 generated by the wave and wave height gathers on the main lever mounting base 5 provided at the center of the deck 4. By shifting the fulcrum hole 39 of the main lever pin 11 to the left and right, the amplitude of the vertical movement of the power point can be adjusted, and a stable rotation is given to the engine part B.
[0012]
【effect】
In the wave device using the floating body of the present invention, the deck is installed so that the floating body is in the front-rear direction with respect to the traveling direction of the wave, so that it always receives the vertical motion of the wave, and the vertical motion of the floating body mechanism unit is rotated by the engine unit Since it can be converted into motion and a reverse rotation force can be obtained by operating the reverse lever, the extracted rotation force can be used as a power source for a power generation or factory.
In addition, when the wave is small or greatly rough, it can be dealt with by operating several models having a floating body (light or heavy).
In addition, a device that generates a large amount of electric power can be formed by converting this enormous energy into a rotational force and rotating the generator at a high speed via a speed increaser, for example.
The present invention focuses on the operation of a pneumatic diaphragm valve that has been used for many years in automatic counting control, and that enormous energy is concentrated on the valve stem at the center of the valve. It can be proved that the wave device using the floating body captures the wave of the sea surface caused by the natural world and generates greater potential energy by the kinetic energy above and below the floating body, that is, the form and use of the floating body, due to the buoyancy from the wave.
