Description

technical field [0001] The invention relates to the field of ocean wave energy power generation, in particular to a wave energy power generation device and a method thereof. Background technique [0002] The types of ocean energy include: tidal energy, wave energy, temperature difference energy and ocean current energy. Compared with other forms of ocean energy, wave energy has many advantages. The power density of wave energy is large, the distribution is wide, and the action time is continuous; The power generation system mainly includes a wave energy capture device, an energy power generation device and a wave energy power generation device. The waves first pass through the wave energy capture device, and then pass through the energy power generation device to convert the wave's low speed, large force, reciprocating and random motion into The high-speed and continuous rotation of the ordinary generator matches, and then passes through the ordinary generator, and finally o...
