Problems solved by technology

The wind energy conversion equipment known to the general public is a kind of fan whose axial direction is horizontal and the blades rotate vertically. In order to obtain higher power, the diameter of the rotating blades is large, the position of the axis center is very high, and it occupies a large area. It is difficult to install and maintain, and the investment cost is high; the other is vertical wind energy conversion equipment with vertical axis and horizontally rotating blades; the existing technology has flat-blade swing wind energy machines, and there are barrier-type flat-blade wind energy machines. The conversion efficiency is relatively low

Abstract

A vertical wind energy machine with rotary vanes has the characteristics as follows: a gear is driven by a rotor which is arranged vertically and rotates horizontally to rotate for outputting power, wherein the rotor consists of a transmission shaft, a rotating shaft beam and a plurality of annular arrays of rotary vanes with a plurality of cambered surfaces, the windward surface of each rotary vane consists of the plurality of cambered surfaces, thus changing the windward angle of the vane and increasing the air resistance and the effective working scope of the wind surface; the back of the rotary vane is a smooth plane for reducing the resistance, and the revolving shaft of the rotary vane is arranged eccentrically and utilizes the asymmetric force applied at two sides thereof to obtain auto rotation power; when the wind is blowing, the cambered surfaces of the rotary vanes accept the wind force for generating thrust and are prevented and limited by a bumper guard, the rotary vanes use the biggest work area to accept the wind force fully and drive the rotor to rotate; and when rotating to the backs of the rotary vanes and bearing the wind force action, the rotor rotates automatically downwind and takes the side direction as wind surface due to the asymmetric force applied at the two sides of the rotary vanes, thus obtaining the smallest wind area, realizing unilateral force of the rotor and resulting in high-power rotation.

Description

Technical field [0001] The invention belongs to a device for converting wind energy into kinetic energy. Background technique [0002] Converting wind energy into kinetic energy is an environmentally friendly, economical and practical technology. The wind energy conversion equipment known to the general public is a fan whose axial direction is horizontal and the blades rotate vertically. In order to obtain higher power, the diameter of the rotating blades is large, the position of the axis is very high, and it occupies a large area. It is difficult to install and maintain, and the investment cost is high; the other is a vertical wind energy conversion equipment with vertical axis and horizontally rotating blades; the existing technology has a flat-blade swing wind energy machine, and a barrier-type flat-blade wind energy machine. The conversion efficiency is relatively low. Contents of the invention [0003] In order to effectively utilize wind energy and convert wind en...
