Wind turbine impeller

Abstract

The invention relates to a wind turbine impeller which comprises an impeller main shaft, a bracket, blade components and a special size rail. The wind turbine impeller adopts the concrete structure that the bracket comprises a shaft sleeve and a plurality of cantilever brackets; the cantilever brackets are distributed and fixedly installed on outer walls at two ends of the shaft sleeve at equal intervals in the radial direction; the cantilever brackets at the two ends of the shaft sleeve form one-to-one correspondence to form a plurality of groups; five groups of the cantilever brackets are distributed and fixedly installed outside the shaft sleeve at equal intervals as shown in a figure of an embodiment; one blade component is articulated with end parts of each group of the cantilever brackets; the blade component is driven to rotate around the impeller main shaft; and the special size rail used for controlling the angle of the blade component is installed on the impeller main shaft on one side of the blade component. The impeller has simple structure and high efficiency, is low in cost and convenient to use and install, has high practicability and wide application range, overcomes the disadvantages that the wind energy stressed area of an original fixed blade is small, the hindered area is relatively large, the efficiency is low, and the like, and adds an efficient wind turbine technology for the wind power generation industry.

Description

technical field [0001] The invention belongs to the field of wind power generation, and relates to a generator, in particular to a wind power generator impeller. Background technique [0002] Wind power generator is a clean energy that converts wind energy into mechanical energy and then into electrical energy. Wind power has good regenerative performance and no pollution. It is the focus of attention of countries all over the world. At present, wind turbines are mainly divided into horizontal-axis wind turbines and vertical-axis wind turbines. The wind-blocking blades are all rectangular frame or blade-shaped fixed structures, and their starting resistance and rotation resistance are relatively large, and the blades at the windward position Insufficient utilization of wind power. [0003] After searching, the following relevant patent documents were found: [0004] A universal wind generator (CN202073714U) utilizing the wind in nature, which is composed of a main wind-blo...
