Abstract

The invention relates to the technical field of wind power generation, in particular to a wind power generation device with adjustable fan blades. The wind power generation device comprises a vertically-arranged main rotating shaft, the bottom of the main rotating shaft is connected with a power generation device, a rotating frame is arranged at the top of the main rotating shaft, the rotating frame is connected with fan blades through a secondary rotating shaft, and a rotating angle controller used for adjusting the inclination angle of the fan blades is arranged between the secondary rotating shaft and the rotating frame. The inclination angle of the fan blades can be adjusted according to the wind speed, the wind area of the fan blades is changed, when the wind speed is too high, the fan blades incline, the wind area is reduced, and the rotating speed is reduced. When the wind speed is reduced, the inclination degree of the fan blades is reduced, the wind area is increased, the rotating speed is increased, the influence of the wind speed on the rotating speed of the fan blades is reduced, the power generation effect is more stable, and the strong wind resistance is improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind power generation device with adjustable blades. Background technique [0002] In order to make better use of wind energy, for a long time, people have designed various structural forms of wind power generators. As a clean and renewable energy, wind energy has attracted more and more attention from all over the world. The use of wind power to generate electricity is very environmentally friendly and can The power generated is enormous. [0003] The angle of the blades of the commonly used vertical axis wind turbines is fixed, and the wind collecting area and angle of the blades are greatly restricted. Changes, unstable working efficiency, reduced the power generation capacity of the fan, shortened the service life of the generator, and the ability to resist strong winds has also been limited to a certain extent. Contents of the invention [0004] The purpo...
