Detailed ways

The floating ratchet wave energy generating device of the present invention will be further described in detail below with reference to the accompanying drawings.

As shown in Figure 1, an ocean wave energy generating device, the present invention is composed of three parts: a wave energy absorbing device, a conversion device and an output device. The absorption device is arranged on the inclined slideway of the box body 1 , and the conversion device and the output device are arranged inside the box body 1 .

The floating ratchet wave energy generating device is half submerged in water, and the float 2 moves along the slideway of the box body 1 along with the motion of the waves. When the wave crest comes, the horizontal velocity and longitudinal velocity of the wave impact the float 2, the float 2 absorbs the force in two directions and is affected by the buoyancy force immersed in the water, the resultant force in the direction of the float 2 is less than the gravity in the direction of the weight 10, therefore, the float 2. Move upward along the slideway, that is, the chain 5 moves toward the weight 10, thereby driving the built-in ratchet 7 to rotate. The built-in ratchet 7 is coaxial with the transmission gear 16, driving the transmission gear 16 to rotate, and the transmission gear 16 and the transmission gear 16 are coaxial. The intermediate gear 14 meshes to drive the intermediate gear 14 to move. The intermediate gear 14 meshes with the output gear 12 to drive the output gear 12 to move. The output gear 12 is installed on the output shaft 13, and the output shaft 13 is connected to the generator 9 with a coupling 11. And then make the generator 9 in the working state to generate electric power. When the crest recedes and the trough arrives, the buoy 2 loses the force brought by the lateral velocity and longitudinal velocity brought by the crest of the wave, and the buoyancy it receives is also greatly reduced, and its own mass is greater than that of the weight 10. Finally, under the influence of the gravity difference, it moves downward along the slideway, and the chain 5 moves down the slideway along with the float 2. At this time, due to the effect of the built-in ratchet 7, the generator 9 does not rotate in reverse, and is temporarily in the Stop working and wait for the arrival of the next peak. When the next wave crest arrives, the built-in ratchet 7 drives the generator 9 to work again, and the cycle repeats, finally making the generator 9 generate electricity continuously.

Fig. 2 is an appearance diagram of the present invention, as can be seen from Fig. 2, only the float 2 can directly contact with seawater, and other parts of the device are not easily corroded, and the stability and reliability are improved.

Fig. 3 is a schematic diagram of a built-in ratchet. The gear 7a is equipped with an external meshing ratchet mechanism, the ratchet 7b is arranged on the transmission shaft 8, and the ratchet 7c is fixed inside the gear 7a.
