Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wind power generation devices, in particular to a vertical axis double rotor wind power generation device. BACKGROUND

[0002] The vertical axis double rotor wind power generation device is a kind of wind power generation equipment, and its core feature is to adopt upper and lower wind wheel structure and double rotor structure. This design realizes the opposite rotation of rotor coil and rotor magnetic pole in double rotor structure through the reverse effect of reverse box device. Compared with single wind wheel structure, double rotor structure can double the swept area, thereby improving the output power and reducing the minimum wind speed available, and has a wider application scenario. The vertical axis double rotor wind power generation device makes two rotors rotate in opposite directions through the design of double rotor structure. This design offsets the periodic change of blade torque and increases the utilization rate of wind energy. Two wind wheels can cooperate with each other to increase the wind energy capture area and reduce the resistance of the blades, thereby improving the conversion efficiency of wind energy.
