Problems solved by technology

However, the size of the blades of the current single wind turbine vertical axis generator should not be too large, so that the output power is limited. It is necessary to further increase the output power and reduce the available minimum wind speed
[0004] In view of the above-mentioned problem of limited power of the current vertical-axis wind power generator, it is necessary to provide a new type of vertical-axis wind power generation structure, which can effectively increase the output power of the vertical-axis wind power generation structure, and can reduce the available minimum wind speed, so as to have more Broad application prospects

Abstract

The invention relates to the field of wind power generation, and discloses a vertical axis wind power generation structure capable of achieving high power. The vertical axis wind power generation structure comprises an upper-layer wind turbine structure, a lower-layer wind turbine structure, and a double-rotor structure. The reverse action of a reverse box device is adopted to finally allow a rotor coil and a rotor magnetic pole in the double-rotor structure to counter rotate and generate power. Compared with the single wind turbine structure, the double-layer wind turbine structure can double the wind sweeping area, the output power of the wind power generation structure can be increased, the available lowest wind speed can be reduced, and the vertical axis wind power generation structure has the wider application scenes.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a high-power vertical axis wind power generation structure. 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 are divided in...
