The invention provides an ocean platform for wave power generation and belongs to the technical field of ocean engineering. The ocean platform for wave power generation comprises a platform body, a floating box and a plurality of vertical pillars. Installing platform bodies protruding towards to the two sides are arranged at the upper ends and the lower end of the vertical pillars correspondingly, two power generation mechanisms are arranged between the two installing platform bodies, and each power generation mechanism comprises a generator, a floating body, at least one first chain wheel and at least two second chain wheels. The generators are fixed to the installing platform body located at the upper ends of the vertical pillars, third chain wheels are fixedly connected to the ends of input shafts, and the first chain wheels are rotatably arranged on the installing platform body located at the upper ends of the vertical pillars. The second chain wheels are rotatably arranged on the installing platform body located at the lower ends of the vertical pillars, the first chain wheels, the second chain wheels and the third chain wheels are connected in a transmission mode through chains, the two floating bodies are in one-to-one correspondence with the two power generation mechanisms, and the floating bodies are arranged between the two installing platform bodies and fixed to the chains. According to the ocean platform for wave power generation, the wave energy is adopted for power generation, energy consumption is low, and pollution is avoided.
