The second unidirectional rotation structure has substantially the same composition as the first unidirectional rotation structure, and will not be described herein.

Wave energy is obtained by adopting a float type, and when the float fluctuates up and down relative to the main body, the crank connecting rod is driven to rotate around the fixed shaft in the forward and reverse directions, so that the up-down linear motion is converted into rotary motion.
When the floater drives the crank connecting rod to rotate clockwise, the ratchet wheel of the second unidirectional rotating structure on the right side is in a transmission state to drive the fourth main gear 13 to rotate clockwise, the fourth main gear 13 drives the fourth intermediate gear 12 to rotate anticlockwise, the fourth intermediate gear 12 drives the fourth auxiliary gear 11 to rotate clockwise, the fourth auxiliary gear 11 drives the third rotating shaft 50 to rotate clockwise, the third rotating shaft 50 drives the gear 16 to rotate clockwise again, and the gear 16 drives the gear 10 to rotate anticlockwise, namely the generator rotating shaft 7a is driven to rotate anticlockwise at the moment. The left wave ratchet wheel is in a sliding state, so that interference can not occur.
Similarly, when the float drives the crank connecting rod to rotate anticlockwise, the ratchet wheel of the second unidirectional rotation structure on the left side is in a transmission state, and drives the third main gear 15 to rotate anticlockwise, the third main gear 15 drives the third auxiliary gear 14 to rotate clockwise, the third auxiliary gear 14 drives the third rotating shaft 50 to rotate clockwise, the third rotating shaft 50 drives the gear 16 to rotate clockwise again, and the gear 16 drives the gear 10 to rotate anticlockwise, namely, the generator rotating shaft 7a is driven to rotate anticlockwise at the moment.

The pawls of the first unidirectional rotation structure and the second unidirectional rotation structure are each provided with a return tension spring 9c. The ratchet pawl at one side of the first unidirectional rotating structure and the first unidirectional rotating structure is reset and is not matched with the inner ratchet wheel when in transmission.
The invention has the advantages that:
1. no matter how the tide and the wave direction are changed, the generator body and the generator shaft only rotate unidirectionally and relatively, and the coupling of the generator body and the generator shaft does not generate motion conflict to influence the power generation efficiency;
2. the two types of ocean energy sources can be collected and integrated into the same equipment to generate power;
3. the tidal current energy and the wave energy are output, and the final single output of the power generation is coupled, so that the number of output sources of the power generation is reduced, complicated electric energy processing processes and equipment can be reduced, and the difficulty and cost of ocean energy power generation grid connection are reduced.
