Problems solved by technology

[0002] Most of the current wind turbine blades adopt a single-piece structure, which is lacking in wind energy absorption; and the structure is too simple, close to a flat plate, so that the strength in the vertical direction is reduced. At present, most of them use thicker materials. to make up for it, thus increasing the cost of the blade

Embodiment Construction

[0006] In specific implementation, the blades can be made wider. On the abdomen of the blades, the inclination and number of air outlets can be designed according to the wind speed and wind pressure ratio. The number of increased air outlets is generally selected between 1 and 6; at the same time, to ensure The wind pressure suffered by the blades, the more air outlets, the better.

[0007] The material of the blade can be made of dried bamboo fiber, absorb saturated ceramic slurry, and then be cured and sintered at 150-300 degrees Celsius in an oxygen-free environment for anti-corrosion and reinforcement; then bonded with unsaturated resin or cured glue to form. A metal keel can be added in the middle of the blade to improve the strength.

Abstract

YThe multi component structure of the vanes of an aerogenerator aims to solve the low absorbing efficiency and strength and costly feature of the existing aerogenerator with vanes of multi component fault wind exhaust, improving wind power absorbing rate 15%, improving power supply due to the expansion of vane area by 20% and reducing cost by10% with the vanes of the same strength.

Description

technical field [0001] The invention relates to a blade of a wind power generator, in particular to a multi-component structure of a blade of a wind power generator. Background technique [0002] Most of the current wind turbine blades adopt a single-piece structure, which is lacking in wind energy absorption; and the structure is too simple, close to a flat plate, so that the strength in the vertical direction is reduced. At present, most of them use thicker materials. To make up for it, so the cost of the blade is increased. Contents of the invention [0003] The task of the present invention is to design and put into production wind power generator blades with good energy absorption effect, high strength and low cost. [0004] The present invention adopts the blade structure with multi-unit staggered air discharge ports. When the wind blows to the blade, the wind pressure formed on the surface of the blade will be difficult to rise after reaching a certain limit, resu...
