A floating type wave power generation system is characterized in that the system consists of eight sets of lever-type floating bodies and a hydraulic energy accumulation converter with the hydraulic pump function. On a floating workbench 7, eight sets of levers 2 and a floating body 1 are connected through supporting hinge bearers 10 and 11; in this way, the highly undulating displacement caused by waves can be converted to relatively lesser displacement of a piston rod 4, and the minor force that the floating body bears can be converted through the lever to the major force on the piston rod. The piston rod drives a hydraulic tank 3 to switch and transmit the hydraulic energy through a connecting oil pipe5, a high-pressure oil pipe6, a hydraulic oil tank and four no-return valves of each set to a hydraulic motor in a hydraulic power generation control chamber 9; in this way the generator is driven to work. The present system can absorb, convert and accumulate the intermittent unstable wave energy in a highly effective way and can buffer the destructive effect of waves. The floating platform can be suitable to different marine space by adjusting the length of an anchor chain 8. And in various sea conditions, kinetic energy and potential energy possessed by waves in the sea surface can be converted and accumulated as hydraulic mechanical energy by utilization of the wave drop; thus the generator is driven to unremittingly provide electric power.
