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.

Abstract: An air-liquid dual control anti-rolling control system for a floating offshore wind turbine in offshore deep sea comprises an equipment compartment and three closed TLCD loop units. The equipment compartment is arranged above box girders; and each TLCD loop unit mainly forms a closed loop by a liquid tank, an air tube and a liquid tube and is embedded into the structure of a floating foundation. The system of the present invention has simple structure, easy installation, detachability, easy replacement and convenient use. The system of the present invention has universality, the designed TLCD loop units are independent of each other, and the start and stop of each TCLD loop unit is entirely coordinated and scheduled by a control module, which is easy to expand. The system of the present invention can realize intelligent autonomous control. By analyzing the measured motion parameters of the floating offshore wind turbine foundation, the control module autonomously determines the TLCD loop unit to be started according to the swing direction of the floating offshore wind turbine foundation, and determines to start an air-control module or liquid-control module of the TLCD loop unit according to the swing frequency of the floating offshore wind turbine foundation, as well as the resistance value of a slide rheostat in an air-control module or the rotational speed of motors of water-turbine sets in a liquid-control module.
