Problems solved by technology

The horizontal axis scheme mainly uses the lift force of the blades to do work. The advantage is that the power coefficient is high, and the disadvantage is that the direction of the wind needs to be adjusted according to the change of the wind direction, and the tower bears a large bending moment; the vertical axis scheme is more diverse, mainly resistance type , lift type and hybrid type, resistance type includes S type, wind cup type, etc., its advantages are simple airfoil, good self-starting type, but the wind power utilization coefficient is not high; lift type includes H type, Φ type, etc., its advantages The wind energy utilization rate is high, but the disadvantage is that it needs a special airfoil and the self-starting performance is not good; the hybrid type has the advantages of both lift type and drag type, but the structure is more complicated

Abstract

The invention discloses a self-adaptive variable-pitch vertical axis wind power generator driving device and a wind power generator, wherein the wind power generator driving device includes a tower, and a wind wheel and a motor are installed on the top of the tower, and the wind wheel includes several blades, each blade is equipped with an adaptive pitch device, and the adaptive pitch device is installed on the rotor of the motor; the tower is also equipped with a wind gathering hood, and the wind gathering hood is located at Below the wind wheel, the wind gathering shroud is used to gather wind energy from various directions and blow it vertically to the wind wheel, so that the wind wheel drives the rotor of the motor to rotate under the action of wind speed to generate electric energy.

Description

technical field [0001] The invention belongs to the field of wind power generation, and in particular relates to a self-adaptive variable pitch vertical axis wind power generator drive device and a wind power generator. Background technique [0002] my country is rich in wind energy resources, and wind power is developing rapidly. Wind turbines are mainly divided into horizontal axis and vertical axis. Large-scale wind turbines generally adopt horizontal axis schemes, and small wind turbines have their own applications for horizontal axis and vertical axis schemes. The horizontal axis scheme mainly uses the lift force of the blades to do work. The advantage is that the power coefficient is high, and the disadvantage is that the direction of the wind needs to be adjusted according to the change of the wind direction, and the tower bears a large bending moment; the vertical axis scheme is more diverse, mainly resistance type , lift type and mixed type, resistance type include...
