One-time integral paint spraying method for paint coating of wind power blade and paint spraying special tool

Abstract

The invention discloses a one-time integral paint spraying method for a paint coating of a wind power blade. The one-time integral paint spraying method comprises the following steps of: preparing before painting; preparing a blade; performing one-time integral painting on the blade; hanging the blade on the painting special tool; then, transporting to a paint spray booth; then, performing paint spraying by a single man and a single gun from a poly styrene (PS) face from the direction of a blade tip to the direction of a blade root gradually so as to finish one-time integral paint spraying of the blade. According to the one-time integral paint spraying method for the paint coating of the wind power blade, the operation time is greatly shortened, and the product quality is ensured; certain frequent quality problems are thoroughly solved; the problem that the blade is not attractive in appearance is solved; not only is the production efficiency increased and the product quality improved but also the material and the labor cost are saved; and a certain environmental-protection action is performed in a certain sense. The one-time integral paint spraying method for the paint coating of the wind power blade is suitable for comprehensive popularization and application.

Description

technical field [0001] The invention belongs to the technical field of paint spraying, in particular to a one-time integral spraying technology of paint coatings of wind power generation blades. Background technique [0002] As a key component of wind turbines, wind power blades have been exposed to the atmosphere for many years, and their surfaces have been eroded by ultraviolet rays, acid rain, smog, and wind and sand for a long time, which seriously affects the life of the product. The paint coating on the surface of wind turbine blades not only plays the role of beautifying the appearance, but also has an effective protective layer for the structure of the blades, so that the surface of the blades is protected from the harsh external environment. [0003] In the current ever-changing market economy, the life expectancy of wind turbines is constantly increasing. At present, the service life of wind power blades is required to be more than 20 years. The paint coating is pa...

Problems solved by technology

The traditional paint operation methods mainly include roller coating method and spraying machine spraying method. Roller coating method is easy to cause problems such as uneven paint thickness, inferior appearance, and many quality problems; spraying method is a commonly used method at present, but it cannot achieve blade paint The overall one-time spraying, multiple repair spraying will easily cause waste of materials and labor, and the operation cycle is long and the quality is unstable
