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.

    本发明涉及一种带有保护装置的海上风力发电装置,包括风力发电装置,所述风力发电装置包括支撑杆和机壳,所述机壳内设置有发电机组和浮力机构,所述浮力机构包括转动组件及在转动组件带动下的升降组件,所述转动组件包括若干个叶轮,所述转动组件上设置有开合组件,所述开合组件包括两个迎风口,所述升降组件上设置有浮力组件,所述开合组件用于切换两个迎风口的闭合状态,若干个所述叶轮在转动的同时带动升降组件进行升降,并在升降的过程中对浮力组件进行充气或抽气,减小因海上风力大小的波动对风力发电机造成的整体摇晃,提高了发电机组的工作效率,在一定程度上稳定电网电压、频率,防止电能质量下降,保证电网正常运行。
