Vertical axis wind generation device

Abstract

The invention relates to a vertical axis wind generation device. The vertical axis wind generation device comprises left and right wind energy acquisition parts, a front bracket part, a fixed vertical shaft part, a rear bracket empennage part, a splitter plate, left and right generator parts, a regulating motor and the like, wherein the left and right wind energy acquisition parts respectively consist of a wind deflector and a coaxial wind wheel. According to the invention, due to the adoption of the wind deflector form, the windward area of the device is increased, the slewing resistances of non-work doing regions of the wind wheels are reduced, the utilization rate of the wind energy is improved, the output power is improved and the breeze starting performance is improved. According to the rotating speeds of generators, the windward area is changed by a windward included angle of a regulating device, so that the wind resistance capacity of the device is improved and the stability of the output voltage is improved. Due to the adoption of a structure of upper and lower air ducts and the upper and lower coaxial wind wheels, the problem that due to different heights, the wind speeds are different, so that the generating efficiency is influenced is solved. The diameters of rotating wind wheel parts are relatively small, so that the device has a simple structure and the difficulty and cost of manufacturing, transportation and installation are reduced.

Description

technical field [0001] The invention relates to a device for generating electricity by wind power, in particular to a vertical axis wind power generator capable of realizing high rotational speed and high efficiency, and belongs to the technical field of wind power generation. Background technique [0002] The development of wind power generators has become a very important way of global energy development. Parallel axis and vertical axis wind turbines are two basic methods. [0003] The length of the blades of large parallel-axis wind turbines has been developed to the limit, and it is very difficult to increase the power of the wind turbine due to the constraints of transportation and manufacturing. The blades of large parallel-axis wind turbines are very long, and the blade tip speed is very high, so the noise is very high and pollutes the environment. [0004] The vertical axis wind turbine has low noise and is easy to transport, install and maintain. Therefore, verti...

Problems solved by technology

[0006] 1. Existing horizontal axis or vertical axis wind turbines; due to the reverse resistance of the blades during rotation, wind resistance and other issues, the width of the blades cannot be made very wide, so the existing horizontal axis or vertical axis wind turbines The wind receiving area is not large, so the utilization rate of wind energy is low, and the start-up wind speed is required to be large
