The wave energy generation device has the advantages that the whole part needs to be broken into parts to fully utilize the wave, the whole part needs to be broken into parts to improve the power, and the wave is wave energy and has the characteristics of disorder, superposition and disorder, so that the energy picking body in the wave power generation is not limited by the size, and the point floating restriction can be generated inevitably.
