The invention can realize uniform spraying of the insulator.

Description

technical field [0001] The invention belongs to the technical field of substation live maintenance operations, and in particular relates to a substation insulator anti-pollution flashover paint spraying robot system and a spraying method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] Regular cleaning of substation equipment and anti-pollution flashover paint spraying is an effective means to maintain the original insulation level of equipment, prevent pollution flashover accidents, and ensure reliable operation of the power grid. Substation post insulator anti-pollution flashover coating spraying is a method to improve the hydrophobicity of the insulator surface by spraying anti-pollution flashover coating on the surface of substation post insulators. It is an effective and necessary anti-pollution flashover method with significant econ...

AI Technical Summary

Problems solved by technology

At present, spraying anti-pollution flashover coatings on post insulators is mainly done by manual spraying by workers, which can flexibly spray different positions of insulating porcelain parts, but there are the following shortcomings: (1) A large amount of paint is not sprayed on porcelain parts but sprayed into the air , resulting in serious waste and pollution to the surrounding environment; (2) The construction quality mainly depends on the experience of the construction personnel, which creates conditions for the construction team to cut corners and materials, and the quality of the coating is difficult to guarantee; (3) During the construction process, the construction personnel need feet It is not safe to step on the surface of the porcelain bottle, hang the safety rope on the pillar of the porcelain bottle, and easily damage the porcelain umbrella skirt;

[0005] The current automatic spraying mechanism is usually designed for circular spraying based on the specific shape of the insulator, but it is difficult to ensure whether the insulator is located in the center of the circle, and it can only be adjusted manually to ensure uniform spraying;

[0006] The position of the spraying mechanism relative to the insulator is fixed, which means that the spraying of the paint is relatively concentrated, and it is easy to appear uneven. However, the insulator includes multiple concave areas in the longitudinal direction, which is prone to dead angles that are difficult to spray, and the uniformity of spraying is difficult to guarantee. ;

[0007] Whether the spraying is uniform can only be checked manually, and it is easy to measure inaccurately and make up too much when repainting the thin coating area
