The wind power generation tower barrel is a tower pole of wind power generation, and the tower barrel is used as a bearing part in the wind turbine generator, so that vibration generated in the running process of the wind turbine generator can be effectively absorbed, and the running stability of the wind turbine generator is effectively guaranteed. At present, when the construction of a large wind turbine tower is carried out, a cone, a steel cylinder and a barrel-shaped process combining the cone and the steel cylinder are mostly adopted. Generally, a tower barrel of a wind turbine generator is divided into 3-4 sections, the tower frames are connected by adopting an integral forging method, a tower barrel plate is mainly made of structural steel, the corrosion resistance of the steel material is poor, and the surface and the barrel wall of the tower barrel plate need to be sprayed with paint to form an anticorrosive coating. The existing anticorrosive spraying for the tower barrel mainly has the following problems:
1. the method of rolling brush is generally adopted for the anticorrosion spraying of the tower drum, and because the tower drum has vertical inclination, partial surface omission inevitably exists when the tower drum is brushed by adopting the rolling brush method, so that the corrosion and aging of the tower drum are accelerated. Therefore, the painting of the tower cylinder needs to be performed by the relevant staff by adopting an airless spraying method.
2. During painting, the relative humidity of the surface is required to be ensured not to exceed 80%, and the temperature of the painted surface is higher than the ambient temperature of a construction site by about 3 ℃. During painting, it is necessary to ensure that the paint height is consistent with the maximum and minimum temperature values of the ambient air and the surface of the part, which are specified by the paint supplier, and cannot exceed the limit.
3. Because the tower section of thick bamboo of wind turbine generator system divide into 3 ~ 4 sections, through flange joint between the adjacent tower section of thick bamboo, and the existence tapering between the upper and lower tower section of thick bamboo, therefore the junction between the adjacent tower section of thick bamboo produces deviation and gap easily, and the junction will cause the paint surface damage of tower section of thick bamboo junction because the atress is uneven to lead to tower section of thick bamboo wall to rust, cause equipment damage and induce the incident.
