Abstract: The present invention provides an independent wave energy power generation buoyancy tank based on a principle of liquid sloshing. A shape of the independent wave energy power generation buoyancy tank is an oblate spherical floating sphere, and crash pads are arranged along the middle direction and the circumferential direction of the buoyancy tank. A hatch cover is installed at the top of the independent wave energy power generation buoyancy tank, and a washer is arranged at the contact between the hatch cover and the floating sphere 9. A signal lamp is installed on the hatch cover. An anchoring ring and a cable socket are installed at a top side of the independent wave energy power generation buoyancy tank. Four sand injection and discharge valves are uniformly arranged on the upper part of the independent wave energy power generation buoyancy tank along the circumferential direction.
