Offshore wind turbine of V-shaped wind wheel structure

Abstract

The invention discloses an offshore wind turbine of a V-shaped wind wheel structure and belongs to the technical field of wind power generation. The offshore wind turbine of the V-shaped wind wheel structure comprises a V-shaped wind wheel, a gear transmission mechanism, a coupler, generator sets and a base platform. The V-shaped wind wheel is provided with three rotating arms which are obliquely arranged. The lower ends of the rotating arms and a wind wheel rotating disc are assembled. The rotating arms are arranged in a radial shape with a wind wheel rotating shaft as the center. A blade is arranged at the upper end of each rotating arm. The lower end of the wind wheel rotating shaft is connected with the generator sets through the gear transmission mechanism and the coupler. The generator sets are installed on the base platform. The base platform is fixed to a seabed through a sea pile or an anchor chain. The offshore wind turbine of the V-shaped wind wheel structure has the beneficial effects of being low in construction cost and convenient to install and maintain, the angle of the rotating arms and the blades can be adjusted according to the offshore wind wave conditions, damage to the blades under the large wind wave condition is avoided, and the service life of the offshore wind turbine is prolonged.

Description

technical field [0001] The invention relates to a wind power generator, in particular to an offshore wind power generator with a V-shaped wind wheel structure, and belongs to the technical field of wind power generation. Background technique [0002] The principle of wind power generation is to use wind power to drive the windmill blades to rotate, and then increase the speed of rotation through the speed increaser to promote the generator to generate electricity. Since wind power generation does not involve fuel issues, nor does it produce radiation or air pollution, it is a clean and environmentally friendly power generation method. Especially with the continuous development and utilization of marine resources, the construction of offshore wind farms is currently forming a boom in the world , many large wind farms stand on the boundless ocean. However, because the construction of offshore wind farms is very difficult, not only the scale of labor and cost input is unexpect...

Problems solved by technology

But most of the existing vertical axis wind turbine wind rotors are located at the top of the wind rotor axis of rotation, in a Φ-shaped or H-shaped structure, and its center of gravity is relatively high, which affects the stability of the wind-driven generator work; in addition, the existing vertical axis The blades of wind turbines are installed in a fixed assembly method. For wind farms standing on the endless ocean, the angle of the blades cannot be adjusted, which can easily cause damage to the blades under strong wind and waves, which affects the performance of offshore wind turbines. service life
