Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of insulating porcelain bottle cleaning, in particular to a high-voltage insulating porcelain bottle cleaning device and method with a multi-axis cleaning ring. BACKGROUND

[0002] In the normal operation process of the power system, a large number of outdoor high-altitude insulating porcelain bottles are equipped in high-voltage equipment of power plants, substations and other places. As a key component to ensure the insulation performance of power equipment, the insulating porcelain bottle is easily attached to dust, oil stains and other types of dirt and impurities when exposed to the outdoor natural environment for a long time. These dirt will gradually reduce the insulation strength of the insulating porcelain bottle. If these dirt are not cleaned regularly, they will easily cause insulation flashover failure under high voltage, seriously threatening the safe and stable operation of power equipment, and even causing major power accidents such as large-scale power outages. Therefore, regular cleaning of outdoor high-altitude insulating porcelain bottles is a necessary operation and maintenance measure to ensure the reliable operation of the power system.

[0003] At present, the cleaning operation of outdoor high-voltage equipment insulating porcelain bottles still mainly relies on traditional manual operation mode, mainly including two implementation approaches: one is to send workers to a high-altitude operation area above 10 meters through the erection of scaffolding for cleaning; the other is to transport workers to the target cleaning position for operation by means of a lifting operation vehicle. However, the above two methods have the following problems: on the one hand, the operation process of erecting scaffolding is complicated, not only requiring a large amount of time and labor cost, but also involving high safety risks in the process of erecting high-altitude scaffolding, which is prone to safety accidents such as falling from a high place and scaffolding collapse. Even if a lifting operation vehicle is used, the workers still need to operate in close proximity to the high altitude, which also poses a safety risk to the workers, and the equipment scheduling, on-site deployment and other links are time-consuming and labor-intensive, resulting in low operation efficiency. On the other hand, the existing few automatic cleaning devices have cleaning blind spots in actual application, which makes it difficult to meet the overall cleaning demand. Due to the special structure of the insulating porcelain bottle, the connection between the grading ring and the porcelain bottle, and the lining of the porcelain bottle skirt form many tricky angle areas. The existing cleaning device has limitations in structural design, and cannot fully and thoroughly clean these areas, resulting in dirt residues and potential risks of insulation flashover, which cannot fundamentally guarantee the safe operation of power equipment.

[0004] In summary, the current insulating porcelain bottle cleaning operation has the problems of high safety risk of high-altitude operation, low operation efficiency, and incomplete cleaning of tricky areas, which has become a key bottleneck restricting the high-quality development of power system operation and maintenance. Therefore, it is of great practical significance and application value to develop a technical solution that can avoid the risk of high-altitude manual operation, improve operation efficiency, and realize intelligent and efficient cleaning of tricky areas of insulating porcelain bottles.
