Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wave power generation device that converts a vertical motion of a wave into a rotational motion in a certain direction and applies a rotational force to a generator to generate power.

[0002]

2. Description of the Related Art Conventionally, wave power generation in which a turbine is rotated by air pressure generated by the vertical movement of waves in a container and a generator is turned has been the mainstream.

[0003]

The conventional methods have the following drawbacks, respectively. (1) Changes in indoor air volume due to up and down waves, that is, the method of converting air pressure into the rotational force of a turbine, both floating type and fixed type, have large devices and low power generation efficiency. (2) The method of converting a wave moving thrust into a rotational force is difficult to implement because the device is large.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention is directed to a floating apparatus in which the apparatus is relatively small and follows the movement of waves inside the power generation section of a cylindrical container, and converts both flows in which the waves move up and down into rotational movements. The above problem has been solved by attaching a body, a balancing line and a free gear, a hydraulic pump, a hydraulic circuit, a hydraulic motor, and the like.

[0005]

[Function] (1) The power generation section of the main body is standing in the sea,
In addition, since a plurality of stabilizers are connected to the lower mooring section and locked on the seabed, they are less likely to be directly affected by the rise and fall of the waves, so that they are fixed in the sea while being a floating body device Is installed stably. (2) The water surface inside the middle vibration chamber of the power generation unit is open with a lattice structure around the upper and lower parts of the vibration chamber.
Ascends and descends just like the outside water surface. (3) The floating body in the vibration chamber moves up and down by the waves,
The counterbore connected to the floating body meshes with the free gear, and is connected to a free gear that operates only when ascending, a free gear that operates only when descending, and a rotating gear that operates when descending. A gear that changes the direction is added, so that the hydraulic pump always applies a rotational force in the same direction. (4) The balancing rope and the balancing weight, which are formed by connecting the wire rope, the chain, and the wire rope, respond to the sway of the wave and transmit a stable rotation to the hydraulic pump. (5) The hydraulic circuit such as the accumulator of the power generation buoyancy chamber provides the number of rotations required for power generation, and keeps the rotation even when the floating body stops moving at the peaks and valleys of the waves, thereby maintaining stable power generation. (6) The floating body is on the sea surface in the vibration chamber, and even if the sea surface is stormy or the like and there is a high wave, a direct shock wave or the like is not applied to the floating body. (7) The buoyancy body and the weight provided in the middle of the mooring section correspond to the rising and falling of the sea surface due to the ebb and flow of the tide, and secure the stability of the entire apparatus.

The floating body moves up and down around the column at the center of the driving chamber, and is rotated in one direction by pinions, free gears, and reversing gears meshing with the rack at the upper center outside the floating body. It converts and supplies stable torque to the hydraulic motor and generator to generate electricity.

The floating body moves up and down together with the spindles above and below the central part, and the rack attached to the spindle gives a rotational force to the pinion of the driving chamber that meshes.
The rotation is converted in one direction by a free gear and a reversing gear, and a stable torque is supplied to the hydraulic motor and the generator to generate power.
A flexible joint provided at the center of the spindle corrects the deviation of the axis and transmits a stable vertical movement.

The up-and-down motion of the floating body gives reciprocating rotation to the gear type hydraulic pump by a normal gear, and the reciprocating output flow is rectified in one direction by a hydraulic circuit comprising a check valve and the like. Then, a stable rotational force is supplied to the hydraulic motor and the generator to generate power.
