Problems solved by technology

When the wind is small, the blades are difficult to rotate and the power generation efficiency is extremely low. Because the blades are made of glass fiber composite materials, they are prone to aging and failure after long-term outdoor use.
[0005] At present, in many border areas of our country, field activity camps, communication base towers, highway lighting, etc., conventional power is difficult to deliver, and power is difficult to supply, and the wind in many areas is not strong enough to drive high-power wind turbines

Abstract

The invention discloses a novel carbon fiber wind driven generator and a preparation method thereof. The novel carbon fiber wind driven generator consists of a wind driven generator support, a composite material blade assembly, a disc generator and a magnetic suspension blade supporting system. The disc generator is fixedly placed on the support, a generator spindle is perpendicular to the ground, a blade assembly center installing sleeve is connected with the end of the generator spindle, all of blades are parallel to the spindle, annular permanent magnets placed on the wind driven generator support and a supporting arm of the composite material blade assembly are opposite in same polarity, and the blade assembly is in a suspension state under the action of a same-polarity repulsive force. The novel carbon fiber wind driven generator is simple in structure and convenient to use, the rigid and flexible combination performance of the blade material is good, and the novel carbon fiber wind driven generator is especially suitable for telecommunication base stations, movable barracks, street lamp illumination and other occasions where conventional power is difficultly transmitted.

Description

technical field [0001] The invention belongs to the field of wind power generation, and is a novel carbon fiber wind-driven generator and a preparation method thereof, which are particularly suitable for providing power supply for occasions such as telecommunication base stations, movable barracks, and street lighting where conventional power is difficult to reach. Background technique [0002] Wind power is a green energy widely favored by various countries. [0003] At present, there are many types of wind turbines, the main structure of which is in the form of a horizontal shaft, the blades are installed vertically to the motor shaft, and the blades are made of glass fiber reinforced resin-based composite materials. [0004] The power of this type of wind turbine is generally large, and it is usually installed on a tuyere with strong wind or on the top of a mountain to generate electricity fixedly. When the wind is small, the blades are difficult to rotate and the power ...
