AI Technical Summary
Traditional oscillating float-type wave power generation devices can only generate electricity when the float moves in one direction, failing to make full use of the reciprocating motion of wave energy, resulting in low energy conversion efficiency.
It employs two ratchet-gear assemblies with ratchet rotation in opposite directions. When one ratchet engages with the drive gear, the other disengages, ensuring that the generator can be continuously driven to generate electricity regardless of whether the waves are rising or falling. Mechanical energy is output alternately through the ratchet-gear assemblies.
It enables continuous wave energy generation, improves energy conversion efficiency and power generation quality, and ensures stable output of the generator during wave reciprocating motion.

When the wave rises, the ratchet 5 of the first ratchet-gear assembly is fixed with the transmission gear 6 through the driving assembly, and rotates in the same direction, and then the input gear 7 engaged with the first ratchet-gear assembly drives the rotating shaft of the generator 10 to rotate and generate power, at this time, the ratchet 5 of the second ratchet-gear assembly is separated from the transmission gear 6; when the wave falls, the ratchet 5 of the second ratchet-gear assembly is fixed with the transmission gear 6 through the driving assembly, and rotates in the same direction, and then the input gear 7 engaged with the second ratchet-gear assembly drives the rotating shaft of the generator 10 to rotate and generate power, at this time, the ratchet 5 of the first ratchet-gear assembly is separated from the transmission gear 6.

[0023] In the embodiment of the utility model, further preferably, the driving assembly comprises a rack 1 and a driving gear 2, the rack 1 is engaged with the driving gear 2, and the rack 1 is used for converting the fluctuation energy of the wave into reciprocating motion.
