Description

Technical Field

[0001] The utility model relates to the technical field of insulator cleaning, in particular to an insulator dirt cleaning device. Background Art

[0002] Insulators are devices installed between conductors of different potentials or between conductors and grounded components that can withstand voltage and mechanical stress. There are many types of insulators with different shapes. Although the structures and appearances of different types of insulators are quite different, they are all composed of two major parts: insulating parts and connecting fittings.

[0003] At present, insulators are wrapped by various particles suspended in the air during the application process (the particles will gradually accumulate on the surface of the insulator under the action of the electric field force and the earth's gravity), and a dirty layer will be formed over time. If there is rain or fog, which makes the surrounding air humid, the insulator may discharge dirty particles, and even flashover may occur on the surface of the insulator. Therefore, it is very necessary and important to clean the shed skirt of the insulator.

[0004] Upon investigation, the Chinese utility model patent with publication number CN116646134A discloses an automatic cleaning device for high-altitude insulators. The device adopts a rain-triggered structure. Under normal conditions, the water collection box is in a vertical state through the counterweight and the insulator. The water collection box accumulates water in rainy weather, and the load force continues to increase until the load force of the water collection box is greater than the gravity of the counterweight plus the force of the magnetic suction component. The movable magnetic block and the limit magnetic block near one end of the water collection box of the limit plate are separated from the magnetic suction state, so that the water collection box rotates to the bottom of the collar, and the counterweight rotates to the top of the collar. The movable magnetic block and the limit magnetic block near one end of the counterweight of the limit plate produce a magnetic suction effect to limit the position, so as to adjust the position of the water collection box and the counterweight. Rotation action, in this process, the cleaning work of the insulator umbrella skirt is achieved by a cleaning brush, and the water collecting box is slidably sleeved on the core rod through a sleeve ring, which makes it impossible to disassemble the cleaning device. When the weather is dry, the inside of the water collecting box is dry, and the sponge is dry, when a flashover occurs on the surface of the insulator, the sponge will be ignited by the electric shock, and then a fire will occur, which poses a safety hazard. In addition, the device is fixed on the core rod, and then multiple cleaning devices need to be installed on each core rod, which will increase the cost.

[0005] Therefore, the utility model provides an insulator dirt cleaning device to solve the above problems. Utility Model Content
