Conductor configuration system of wind power blade, wind power blade and preparing method thereof

Abstract

The invention discloses a conductor configuration system of a wind power blade. The system comprises a conductor containing fixing element and a conductor connected with a pre-embedded element on theouter surface of the wind power blade, the conductor containing fixing element and the conductor are arranged in a blade shell, the conductor is connected with the pre-embedded element through a through hole formed in the blade shell, the conductor containing fixing element is fixedly arranged in the through hole, and is provided with a penetrating-in hole used for allowing the conductor to penetrate in and a penetrating-out hole used for allowing the conductor to penetrate out, and the penetrating-out hole directly communicates with the through hole. The invention further provides the wind power blade and a preparing method of the wind power blade. According to the integral forming characteristics of a wind power blade vacuum guide-in molding forming process, the conductor configuration system is arranged in the wind power blade, and on the premise of ensuring the blade appearance, the connection problem of conductors inside and outside the shell can be solved.

Description

technical field [0001] The invention belongs to the field of wind power generation, and in particular relates to a wire arrangement system, a wind power blade and a preparation method thereof. Background technique [0002] Wind turbine blades are generally manufactured by the Vacuum Introduction Molding (VARTM) process. First prepare the PS surface, SS surface, web and girder in advance, that is, the forming process; then bond the PS surface and SS surface with epoxy structural adhesive, that is, the mold closing process, and finally, perform external surface treatment such as grinding on the blade, That is, the post-processing process. The shape of the outer surface of the blade is closely related to the efficiency of wind power generation. It is very important to keep the shape of the outer surface of the blade consistent with the designed aerodynamic shape. Generally, the power supply and control equipment of the wind turbine are located in the hub or the nacelle, that ...

AI Technical Summary

Problems solved by technology

This method will cause large bends in the layer structure above the wires, which will seriously affect the mechanical properties of the blade body; 2. Hand paste the wires on the outer surface of the cured blade shell, which will greatly affect the shape of the blade. It seriously affects the aerodynamic shape of the blades and affects the power generation efficiency of the fan

[0004] Second, the wires are pre-embedded above the fiber cloth layer (away from the mold side, that is, the inner surface of the blade shell after molding), and the wires are poured into the inner surface of the blade in one piece, and there are the following problems: ①Because the blade infusion process is a vacuum-introduced integrated infusion process, this method is prone to the risk of air leakage at the position of the wire joint, which brings a major risk to the quality of the blade; ②The connected pre-embedded components are generally placed on the lower side of the glass fiber cloth, and are prone to movement during the manufacturing process of the blade. It is not easy to adjust and repair after curing
