Pendulous sea wave energy utilization device based on floating platform

The utility model belongs to the technical field of ocean equipment, in particular relates to a pendulous sea wave energy utilization device based on a floating platform. The pendulous sea wave energy utilization device based on the floating platform comprises a floating platform (1), a pendulum body (2), a hydraulic cylinder (3), an anchor chain (4) and a high holding power anchor (5). The pendulous sea wave energy utilization device based on the floating platform is characterized in that the floating platform (1) is provided with a floating platform bottom (7) and a raised part (6), wherein the floating platform bottom (7) is capable of adjusting self-position and self-height. The floating platform anchored by the anchor chain is provided with a sphere of activity and can especially adjust self-position when wave directions change and adjust self-height when water level is changed by tides. The pendulous sea wave energy utilization device based on the floating platform can adapt to the waves in a self-adaption mode and is simple in structure and convenient to manufacture. Energy utilization efficiency is enhanced.
