Wave power generation device, wave power generation module and wave power generation system

The invention discloses a wave power generation device, a wave power generation module and a wave power generation system.The wave power generation device comprises a power generation unit supporting frame, a swing power generator, a floating power generation assembly, a floating box assembly, a linear power generator and a linear power generator fixing frame, and the swing power generator is rotatably arranged on the power generation unit supporting frame; the floating power generation assembly can rotate relative to the power generation unit supporting frame, and the linear generator is connected with the power generation unit supporting frame through a connecting rod. A photovoltaic panel in the floating power generation assembly floating on the water surface generates power under the irradiation of sunlight, and meanwhile, the floating power generation assembly swings in a reciprocating manner and the wave power generation device moves up and down under the action of the buoyancy of waves and the gravity
