Wind power generation device

Abstract

The invention belongs to development and utilization of clean energy, and relates to a wind power generation device which is used for power generation by using wind energy. The wind power generation device comprises a mounting bracket which is provided with a rotating shaft, and a plurality of blade brackets for providing wind energy are fixedly connected to the rotating shaft; each blade bracketcomprises main brackets located at the upper and lower ends of the blade bracket, and a plurality of auxiliary brackets vertically arranged side by side are installed between the two main brackets; and movable blades are arranged between every two adjacent auxiliary brackets, and the blades, the upper and lower brackets and the auxiliary brackets form a concave shape jointly. According to the windpower generation device, by using the concave shape of the blade brackets, a stress surface with a larger area is achieved, namely that the stress efficiency is improved; meanwhile, the blades as stress carriers can be of removable structures so that resistance of wind power in the same direction to rotation of other blade brackets can be reduced, and the wind power efficiency is improved; the acting force of the wind power for the blade brackets is reduced by a torsion spring through movable expansion of the blades when the wind power is too high; and the speed of the blade brackets is decreased, and the use safety is improved.

Description

【Technical field】 [0001] The invention belongs to the development and utilization of clean energy, and relates to a wind energy generating device for generating electricity by using wind force. 【Background technique】 [0002] Most of the current wind power generation uses the wind to blow the inclined plane of the blade to make it rotate or to rotate the blade bracket installed therein, thereby obtaining electric energy. For a wind power generation device with multiple blade supports, since the blades are fixed, when the wind pushes the blade supports to rotate, it may contain other blade supports and reduce the efficiency of wind power as a whole. The planar structure of the blade supports, It also reduces the wind-receiving area of ​​the blade bracket; at the same time, in order to generate more power, the existing wind power generators often have a large construction size, which increases the difficulty and cost of installation and use, and is expensive and has poor wind ...
