Embodiment Construction

[0023] The structure of the double-wind wheel and double-rotor wind power generator of the present invention will be specifically described below in conjunction with the accompanying drawings.

[0024] see figure 1 , the present invention double wind wheel double rotor wind power generator, comprises frame 5, and casing 10 is fixed on frame 5, and outer rotor 6 is set in casing 10, and inner rotor 8 is embedded in the outer rotor 6. A magnetic steel 9 is arranged on the outer surface of the inner rotor 8 to form a magnetic rotor, and a coil 7 is wound on the inner wall of the outer rotor 6 to form a coil rotor. The end of the inner rotor shaft 3 extending out of the casing 10 and connected to the inner rotor 8 is provided with a forward-rotating wind wheel 1, and the end of the outer rotor shaft 4 extending out of the casing 10 and connected with the outer rotor 6 is provided with a counter-rotating wind wheel 2. Both the forward-rotating wind rotor 1 and the counter-rotating...

Abstract

The invention provides a double-windwheel and double-rotor type wind-driven generator. The double-windwheel and double-rotor type wind-driven generator comprises a base on which a housing is fixedly arranged, wherein an outer rotor in which an inner rotor is embedded is arranged in the housing; a magnet steel is arranged on the outer surface of the inner rotor, and a coil is arranged on the inner wall of the outer rotor in a winding manner, or the coil is arranged on the outer surface of the inner rotor in the winding manner, and the magnet steel is arranged on the inner wall of the outer rotor; wind wheels which are rotated in opposite directions are correspondingly arranged at an outer rotor shaft end part and an inner rotor shaft end part; the outer rotor shaft end part extends out of the housing and is connected with the outer rotor, and the inner rotor shaft end part extends out of the housing and is connected with the inner rotor; the coil is used for outputting the generated electricity through a conductive ring, a carbon brush and an outgoing wire. With the adoption of the double-windwheel and double-rotor type wind-driven generator, the electricity can be generated in a low-wind-speed and weak-wind environment, and moreover, the generating capacity is improved, the cost is decreased, and the low-wind-speed wind-driven generation is practical; the double-windwheel and double-rotor type wind-driven generator has the advantages of being easy to manufacture, safe, reliable, simple to maintain, and free from environmental pollution.

Description

technical field [0001] The present invention relates to a generator, in particular to a double-wind-wheel and double-rotor wind-driven generator, which refers to a wind-driven generator capable of generating power in a low wind speed and light wind environment of 6m-2m / s and greatly increasing the power generation. Background technique [0002] Wind energy is a new energy with the most potential for development among clean and renewable energy sources, and its reserves in my country are quite abundant. [0003] In recent years, my country has made considerable progress in the development and utilization of wind power renewable energy. But as we all know, there are usually the following problems in the construction of wind power: ①. When choosing a good wind farm, the wind speed must be above 10m / s (that is, the wind above level 5 or 6) to effectively generate electricity, and only a few areas in my country can reach this wind speed; ②. Most of them are built in remote mounta...
