Wind power blade surface protection method

Abstract

The invention discloses a wind power blade surface protection method. The protection method is realized by pasting a prefabricated protective coating on the outer surface of a wind power blade, wherein the prefabricated protective coating comprises a coating protective film A, an adhesive, a coating and a coating protective film B; and the method for protecting the surface of the wind power bladeby applying the prefabricated protective coating comprises the following steps of, peeling off the coating protective film A through external force; applying the adhesive to the outer surface of the blade, and smoothly pasting the prefabricated protective coating on the outer surface of the blade and compacting the prefabricated protective coating; and after the adhesive is cured, peeling off thecoating protective film B. According to the method, the wind power blade protective coating is made based on a specific thickness according to requirements, so that one-time forming of the blade protective coating can be achieved, roller coating or spray coating is not needed, the quality problems such as exposed base and color difference of the protective coating cannot be caused due to improperoperation of workers, the thickness of the protective coating is ensured to be uniform and colorless, and the production efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of wind power blade manufacturing, in particular to a method for protecting the surface of a wind power blade. Background technique [0002] Under the dual pressure of the shortage of traditional energy sources and the deterioration of the global ecological environment, wind energy has been widely developed and utilized as a renewable clean energy. Wind energy is the kinetic energy generated by air flow. Power generation technology, wind power generation refers to the technology of converting the kinetic energy of wind into electrical energy through wind turbines. Wind turbine blades are the basic components of wind turbines. In order to ensure that wind turbine blades can resist salt spray, sandstorm, ultraviolet rays and other natural environments during installation The erosion of the blades prolongs the service life of the blades. During the manufacture of wind power blades, it is necessary to add coatin...

Problems solved by technology

At present, in the manufacturing process of wind power blades, the outer surface of the blades is protected by roller coating or spraying polyurethane paint. Regardless of roller coating or spraying, it is mainly achieved by manual operation. Since the thickness of the paint film of a single roller coating or spraying has certain requirements, it must To meet the overall film thickness standard of the coating, it is necessary to repeat roller coating or spraying 4-5 times. A single wind turbine blade requires 6 people to work at the same time for 8-10 hours. Roller coating or spraying is labor-intensive, and the work efficiency is low. The thickness of the coating formed by roller coating or spraying is uneven, and it is easy to cause quality defects such as color difference, rough surface, and exposed bottom. During the process of roller coating or spraying, the volatilization of harmful substances such as thinners in the paint will cause environmental pollution and affect air quality. It will cause damage to the health of the surrounding staff, and the roller coating or spraying process has high environmental requirements, otherwise the surface will easily adhere to particles, which will affect the quality of the protective coating
