Blade structure for wind driven generator

Abstract

The invention discloses a blade structure for a wind driven generator. The blade structure comprises air consumption holes, a baffle plate, a D-shaped steel longitudinal beam, an elastic hinge, a long steel wire, a short steel wire, a baffle plate with a hole, an air consumption hole cover plate and a hook, wherein positions with large windward areas on a blade in an axial direction are provided with a plurality of air consumption holes; one side of the air consumption hole cover plate is connected with the D-shaped steel longitudinal beam through the elastic hinge; the hook is arranged in the middle of the air consumption hole cover plate; the two ends of the short steel wire are connected with the hook in the middle of the air consumption hole cover plate respectively; and one end of the long steel wire is connected with the middle of the short steel wire, and the other end of the long steel wire is connected with a motor on a blade root of the blade. Energy capture of a wind wheel can be reduced so as to keep the rotating speed of the wind wheel below a rated value. Simultaneously, load borne by the blade and impact on the entire wind machine are reduced and the wind machine is prevented from being damaged.

Description

technical field [0001] The present invention relates to the technical field of wind power generation equipment, in particular to a wind power generator blade structure. Background technique [0002] With the requirement of human beings for the ecological environment and the need for energy, the development and development of wind energy has been paid more and more attention. Wind power will become a renewable and clean energy developed on a large scale in the 21st century. As a kind of renewable energy, wind energy has abundant reserves in China. With the continuous improvement of people's understanding of wind power generation and the continuous maturity of small wind power generation technology, its application fields are becoming more and more extensive. [0003] A wind turbine is a power generation device that uses wind energy in nature to convert it into electrical energy. The wind turbine works within a certain range of wind speed. In many cases, it is required that ...
