State Intellectual Property Office of China has released the abstract. According to the abstract, "The offshore wind power generation device with the protection device comprises a wind power generation device body, the wind power generation device body comprises a supporting rod and a machine shell, a generator set and a buoyancy mechanism are arranged in the machine shell, and the buoyancy mechanism comprises a rotating assembly and a lifting assembly driven by the rotating assembly. The rotating assembly comprises a plurality of impellers, an opening and closing assembly is arranged on the rotating assembly, the opening and closing assembly comprises two windward ports, a buoyancy assembly is arranged on the lifting assembly, the opening and closing assembly is used for switching the closing state of the two windward ports, and the multiple impellers drive the lifting assembly to ascend and descend while rotating. And the buoyancy assembly is inflated or deflated in the lifting process, so that the overall shaking of the wind driven generator caused by the fluctuation of offshore wind power is reduced, the working efficiency of the generator set is improved, the voltage and frequency of a power grid are stabilized to a certain extent, the quality of electric energy is prevented from being reduced, and the normal operation of the power grid is ensured."
