Embodiment 1

[0025] Example 1, see Figure 1-6 ,

[0026] A method for installing a lightning protection system for wind turbine blades, comprising the following steps:

[0027] (1) Process the mold according to the normal operation process, lay the release cloth, two layers of glass fiber outer skin cloth, lay the leaf root reinforcement layer, place the main beam, and lay the core material;

[0028] (2) After laying the core material, remove the small core material square with a size of 30mm*30mm at the specified position on the suction surface of the blade according to the design requirements, mark its upper and lower surfaces, and refill the small core material square into the In the 30mm*30mm square hole of the core material, it is used to mark the installation position of the aluminum plate of the lightning receptor. The spanwise error of the marked position is ±20mm, and the chord error is ±3mm;

[0029] (3) After the marking is completed, lay the glass fiber cloth of the leaf root r

Abstract

The invention relates to a wind power blade lightning protection system mounting method. The method is characterized by comprising the following steps that a small marked core material square block ismade at the required position of the suction surface of a blade; a round hole with the diameter of phi 30mm is formed in the position aligned with the marked position; a lightning protection system aluminum plate is mounted, wherein a lightning arrester aluminum plate with a threaded bottom hole is bonded to a lower random type PVC block, the aluminum plate is guided and corrected through a positioning tool, and hand lay-up strengthening is conducted on the aluminum plate; and finally, an aluminum column is mounted, wherein the threaded part of the aluminum column is coated with a layer of conductive paste, the aluminum column is screwed into the threaded hole of the aluminum plate, and the aluminum column flows after the resistance is detected to be qualified. The operation method is simple, the lightning protection system aluminum plate with the hole is mounted in advance, the method is economical, practical, safe and reliable, the blade lightning protection system mounting efficiency is improved, the number of post-processing punching operators can be reduced, and the labor efficiency is high.
