Ocean wave power generation device

The invention relates to the technical field of ocean wave power generation, in particular to an ocean wave power generation device which comprises a supporting column, a power generator is fixed to the top end of the supporting column, a transmission shaft is fixed to the output end of the power generator, and a bracket is fixedly connected to the top of the supporting column. A plurality of sets of supporting assemblies are annularly fixed to the top face of the bracket in a crossed mode at equal angles, and two wave transmission mechanisms are fixedly connected to the tops of the supporting assemblies. According to the wave-blocking device, the multiple wave-blocking plates are arranged on the outer side of the transmission shaft, the wave-blocking plates in different positions face different directions, the wave-blocking plates in different directions can make contact with waves in different directions conveniently, and the wave-blocking plates are pushed to do transverse reciprocating motion by means of
