[0003] The construction of offshore power generation equipment is more complex and requires a large amount of construction work than onshore wind power projects. Due to the particularity of the marine environment, such as strong winds, large waves, and seawater corrosion, higher requirements are placed on the design, manufacture, installation, and operation and maintenance of the equipment. At the same time, most offshore power generation equipment is fixed, installed in specific sea areas and fixed. Although this fixed power generation method is conducive to the stable operation and maintenance of the equipment, it limits its ability to supply power to offshore vessels. Because offshore vessels usually need to operate in different sea areas, and fixed power generation equipment cannot move with the ship and provide power support, this reduces the operating efficiency of offshore vessels to a certain extent. Summary of the invention

At the same time, most of the offshore power generation equipment is fixed and cannot move with the ship and provide power support, which to a certain extent reduces the operating efficiency of marine ships. In the disclosed scheme, the buoyancy ball 1 is connected to the fixed anchor 9 sunk to the seabed through a connecting rope 2, and the gear box 3 is fixed on the connecting rope 2. The gantry-type fixing frame 7 is fixedly or rotatably connected to the gear box 3 and the impeller shaft 10, and the blades 11 are fixedly connected to the impeller shaft 10; when the blades 11 are blown by strong wind, the impeller shaft 10 is driven to rotate. Further, the impeller shaft 10 is connected and rotated with the generator shaft 12 through the bearing sleeve 4, the gear box 3, and the coupling 5, so that the rotor of the generator 6 rotates to generate electricity.
