A wind turbine impeller

Abstract

The invention provides a wind turbine impeller, which is used to solve the problems of low wind-sweeping ability and insufficient power of the wind turbine impeller. The impeller includes a main shaft, n sets of impeller frames, n sets of blades and bearing housings, wherein n is a positive integer not less than 1; each set of impeller frames includes a first impeller frame and a second impeller frame; the first The impeller frame and the second impeller frame take the main shaft 1 as the axis of symmetry, and are fixedly mounted on the main shaft in mirror image symmetry; the blades include first blades and second blades; the first blades are movably installed on the first impeller frame, and the second The two blades are movably installed on the second impeller frame; the first blade and the second blade are connected as a whole through connecting parts and move synchronously; the main shaft 1 is vertically installed on the bearing seat. The invention has the characteristics of enhanced wind-sweeping ability, simple structure, large generating power range, wide application range and the like.

Description

technical field [0001] The invention relates to a wind turbine impeller and belongs to the technical field of wind power generation. Background technique [0002] In recent years, with the continuous improvement of people's living standards, the consumption of energy has also increased, and the problem of energy shortage has gradually attracted people's attention. In order to realize the effective utilization of energy and develop the use of renewable and clean energy, green energy has become the focus of worldwide attention. As an inexhaustible renewable energy, wind energy has gradually attracted the attention of the world's energy utilization.
