Embodiment Construction

[0041] A blade for a vertical axis wind power generator and its manufacturing process according to the present invention will be described in detail below with reference to the accompanying drawings. figure 1 , figure 2It is a schematic diagram of the cross-sectional structure of the blade of the blade for the vertical axis wind power generator of the present invention in two main beam forms. The blade adopts inner, middle and outer three-layer structure; the outer structure is thin-walled skin 1, and the surface is processed into the shape required by the blade; the dimensional accuracy and surface finish of the blade are guaranteed to obtain the required aerodynamic performance and withstand the aerodynamic load on the blade surface And protect the middle filling body from the sun's ultraviolet radiation aging, air corrosion and oxidation. The middle structure is the filling body 2, which can fill all or part of the space between the skin and the main beam, and play the ro...

Abstract

The present invention relates to wind generating technology, and is one vane for vertical shaft wind-driven generator and is making process. The vane is one three-layer structure including an outer layer of thin wall coating in the required vane shape, a middle layer of light material stuffing and an inner layer as the main beam with ends stretched beyond the vane and in box-shaped or dumbbell-shaped cross section. The making process of the vane includes making vane sections in the equal length and the required three-layer structure on the main beam, and connecting the sections firmly to complete the vane. The vane of the present invention has low manufacture, transportation and installation cost and is easy to make in large size.

Description

technical field [0001] The invention relates to a blade for a vertical axis wind power generator and a manufacturing process thereof, belonging to the field of wind power generators, with patent classification numbers: F03D3 / 06, F03D9 / 00, F03D11 / 02. Background technique [0002] At present, there are mainly two kinds of known wind power generators, horizontal axis wind power generators and vertical axis wind power generators. These two types of wind turbines have different blade installation forms, operating conditions and stress conditions, so the structural forms, materials used, and manufacturing processes of the blades are also different. [0003] The blades of the vertical axis wind turbine rotate around the axis perpendicular to the ground; the typical vertical axis wind turbine is Darrieus type, the wind rotor is installed vertically, the blades adopt the shape of skipping rope, and the two ends of the blades are fixedly connected to the rotor shaft. Due to the opera...
