[0001] The utility model relates to the field of paint spraying equipment, in particular to a remote-controlled spraying device for a self-spraying tank. Background Art

[0002] As the ecological environment continues to improve, birds are breeding in large numbers. With the implementation of the national policy of returning forests to farmland, a large number of high trees have been cut down, making power lines and equipment an ideal place for birds to nest. Birds nesting in the exposed parts of power lines and equipment has increased short-circuit grounding faults. At the same time, cleaning bird nests will damage the ecological environment and increase the work pressure and safety risks of front-line power workers. In addition, extremely low temperatures in winter can cause ice to cover the exposed parts of power lines and equipment, which can easily cause power line and equipment failures. Therefore, it is necessary to insulate the surface of the exposed parts of power lines and equipment.

[0003] The existing insulation protection treatments mainly include painting and spraying, and both are manually applied to the surfaces of exposed wires, parallel groove clamps, T-contacts, drop switches, isolation switches, switch cabinets and other components in the 10KV and below distribution system. Manual painting and manual spraying methods mainly involve manually climbing onto the poles and painting the same line with the same color, or spraying with a self-spray can. However, this method requires power outages because people are too close to live lines, which is inefficient. At the same time, it involves power outages, which affects sustainable power supply.

[0004] Therefore, this field needs a new technical solution to solve the above problems. Utility Model Content
