Abstract

The invention relates to the field of wind power generation and discloses a wind driven generator with two opposite wind wheels. The wind driven generator with the two opposite wind wheels is in a structure of double wind wheels opposite in rotation direction, the two wind wheels are used for driving a rotor coil and a rotor magnetic pole to rotate oppositely so as to combine wind energy acquired by the two wind wheels, and the wind energy is outputted in an electric energy form. Due to the fact that the structure of the double wind wheels is capable of realizing twice wind sweeping, compared with a wind driven generator with a single-wind-wheel structure for once wind sweeping, the wind driven generator with the two opposite wind wheels has the advantages of improvement of acquisition efficiency and conversion efficiency of the wind energy, reduction of usable minimum wind speed and wider application range.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a wind power generator with opposite directions and double wind wheels. Background technique [0002] Wind power generation is a process of converting the kinetic energy of gas flow into electrical energy. Its working principle is to use the wind force of gas flow to drive the wind rotor blades to rotate, and then use the speed increasing device to increase the rotation speed to drive the generator to generate electricity. According to the current wind power generation technology, even a breeze with a wind speed of only 3 meters per second can be used for wind power generation, with a wide range of application scenarios. At the same time, because wind energy is a renewable energy source, and wind power generation does not cause radiation or air pollution, wind power generation has become the new darling of the energy industry today. [0003] Existing wind power generators ar...
