Air duct type multi-wind-wheel vertical-axis wind power generation device

Abstract

The invention relates to the technical field of wind power generation, and discloses an air duct type multi-wind-wheel vertical-axis wind power generation device which comprises a tall and upright air duct, steel pipe stand column cross beams and an underground foundation are arranged on the periphery of the air duct for reinforcement, a plurality of vertical axial blade wind wheels are arranged in the air duct, and the plurality of wind wheels are connected in series through a transmission shaft. According to the air duct type multi-wind-wheel vertical-axis wind power generation device, a wind direction rudder can guide a horn-mouth-shaped wind collecting and guiding device to rotate along with the change of the wind direction, so that a horn mouth is accurately in the wind direction state facing incoming wind, wind power can be guided into an air duct body to the maximum extent, the wind power in the air duct body is enhanced through a wind inlet, upward strong airflow is generated, the airflow acts on all the blade wind wheels from bottom to top, all the blade wind wheels synchronously rotate to drive the transmission shaft to generate mechanical energy, a speed-up generator can normally operate through a speed-increasing box to generate electric energy, grid-connected power supply can be achieved, and the power generation function is achieved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a wind cylinder type multi-wind rotor vertical axis wind power generation device. Background technique [0002] Wind energy is an inexhaustible clean energy. People use it to generate electricity, and thus produce many types of wind power generation equipment and devices. Among them, the most common one we see is a wheel with three slender blades. The horizontal axis wind power generation device is the most widely used conventional wind power generation device at present. [0003] However, there are still many unsatisfactory aspects in the above-mentioned horizontal axis wind power generation device, such as being restricted by wind instability factors, it cannot generate electricity normally when the wind speed is lower than 3 meters per second, the stability is not good, and maintenance is very troublesome There is a need for high-altitude operations, as well as ...

Problems solved by technology

[0003] However, there are still many unsatisfactory aspects in the above-mentioned horizontal axis wind power generation device, such as being restricted by wind instability factors, it cannot generate electricity normally when the wind speed is lower than 3 meters per second, the stability is not good, and maintenance is very troublesome There is a need for high-altitude operations, and the difficulty of construction and installation is high. It can be seen that we urgently need a wind-drum multi-wheel vertical-axis wind power generation device to solve these problems existing in the above-mentioned horizontal-axis wind power generation device. question
