Offshore wind power generator with V-shaped wind rotor structure

Abstract

An offshore wind power generator with a V-shaped wind turbine structure comprises a V-shaped wind turbine (1), a gear transmission mechanism (2), a coupling (3), a generator set (4), and a base platform (5). The V-shaped wind turbine (1) is provided with three inclined rotating arms (1-1). Lower ends of the rotating arms (1-1) attach to a wind turbine turntable (1-9). The rotating arms (1-1) are arranged in a radial manner with a wind turbine rotary shaft (1-3) at the center. An upper end of each rotating arm (1-1) is provided with a blade (1-6). A lower end of the wind turbine rotary shaft (1-3) is connected to the generator set (4) by the gear transmission mechanism (2) and the coupling (3). The generator set (4) is mounted on the base platform (5). The base platform (5) is fixed to the seabed by means of marine pilings or anchor chains. The rotating arms (1-1) of the wind turbine are inclined, and the lower ends of the rotating arms (1-1) are directly combined with the wind turbine turntable (1-9), thereby effectively lowering the center of gravity of the wind turbine, ensuring the operational stability of the offshore wind power generator.

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
