Abstract
The invention relates to a wind turbine blade of a wind driven generator. The wind turbine blade of the wind driven generator comprises a suction face casing and a pressure face casing. The suction face casing and the pressure face casing are bent into the shapes required by the blade section profile according to needs. The suction face casing is connected with the pressure face casing through streamlined distributor heads and triangular spoilers. Each of the suction face casing and the pressure face casing comprises a core and skin covering the core. The blade includes a plurality of segments and is assembled by reinforcement of core sheets. The wind turbine blade made of aluminum honey-combed boards is lighter, simple in structure and lower in manufacturing cost. The segmental structure more facilitates conveying and assembly of the wind turbine blade. The materials of the wind turbine blade are more environment-friendly, and materials are saved greatly.
Description
Technical field
The present invention relates to a kind of wind rotor blade of wind generator.
Background technique
Compare the tradition generating, wind-power electricity generation is the pollution-free power-generating mode.In recent years, the wind-powered electricity generation power generating industry develops rapidly, the countries in the world installed capacity of wind-driven power grows with each passing day, the existing wind rotor blade of wind generator overwhelming majority is the material of reinforced plastic glass fibre and carbon fiber, this material weight is heavy, intensity is low, manufacture cost is high, transportation is difficult, and our environment of disposal meeting severe contamination after scrapping.
Summary of the invention
For above deficiency, the invention provides a kind of wind rotor blade of wind generator of new structure.
Main technical content of the present invention is as follows:
A kind of wind rotor blade of wind generator, comprise suction surface housing, pressure side housing, described suction surface housing, pressure side housing bend to the required shape of blade section profile as required, scratching the stream empennage by streamlined shunt head and triangle links together suction surface housing, pressure side housing, described suction surface housing and pressure side housing comprise core and cover in the covering in the described core outside, described blade is divided into some sections, reaches the assembling of whole blade by the curing between the core.
The material of above-mentioned core is aluminium cellular structure sheet material.
Above-mentioned suction surface housing, pressure side buckling of shells degree successively decrease with the gradient of 1:6～1:7.
By technique scheme, the present invention has following advantages at least:
(1), the material of aluminium cellular structure sheet material is lighter, and is and simple in structure, manufacture cost is lower.
(2), the structure of segmented is more convenient for transportation and the assembling of wind wheel blade.
(3), more environmental protection of material of the present invention, and saved in a large number material.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
Description of drawings
Fig. 1 is the structural representation of wind wheel blade;
Fig. 2 is the structural representation of sectional-type blade.
Embodiment
