1. Offshore floating wind turbine based on single-column foundation configuration damper, comprising a fan, a single-column foundation, a cable and an anchoring device, the wind turbine is installed on a single-column foundation, and the single-column foundation is connected with an underwater anchoring device through a cable; It is characterized in that: further comprise hydraulic damper, described hydraulic damper connects underwater anchoring device by cable, described single-column foundation is installed on hydraulic damper, described single-column foundation is built-in with the static ballast tank and dynamic ballast tank of up and down distribution, described static ballast tank is used for providing the main buoyancy of carrying fan, it is matched with the counterweight that is used for lowering the center of gravity of wind turbine, described dynamic ballast tank is surrounded by counterweight, buoyant piston and single-column type foundation shell, and is built-in with pressure spring, One end of the compression spring is connected with the bottom of the counterweight, and its other end is connected with the top of the buoyancy piston, the buoyant piston is connected with the damping piston of the hydraulic damper downwards through the piston rod, the compression spring, the buoyant piston and the damping piston move up or down together with the upward or downward movement of the fan, and then the internal volume of the hydraulic damper is changed, the hydraulic damper is arranged with a plurality of one-way valves, and in the process of changing the internal volume of the hydraulic damper, Through the check valve, the external water body can be injected into the hydraulic damper or the existing water body inside the hydraulic damper can be discharged, so as to realize the dynamic adjustment of the fan damping, so that while improving the structural stability of the fan, it also reduces the force on a part of the cable and anchoring device.
