Description

Technical Field

[0001] The utility model relates to an insulator cleaning aerial work vehicle, which is mainly used for the dirty cleaning operation of the support insulators in high voltage and ultra-high voltage transformer stations. Background Art

[0002] Insulator contamination has always been one of the important factors affecting the safe operation of transmission and distribution lines. Severely contaminated insulators may experience surface discharge flashover accidents, leading to line failures and affecting the safe and stable use of electricity. Post insulators in high-voltage and ultra-high-voltage substations need to be decontaminated regularly.

[0003] At present, there are two main technical routes for the cleaning of pillar insulators. One is to clean the dirt on the insulators with a mixed cleaning fluid and then rinse it with clean water or pure water. The other is to freeze and rinse the dirt with dry ice. There is no dedicated cleaning vehicle for the two technologies at present, and they are mainly cleaned manually. From the perspective of the cleaning solution, the cleaning solution using cleaning fluid is easier to implement and has lower costs. Taking the cleaning fluid solution as an example, the local manual climbing operation is usually adopted at present. Multiple people work in a group at a time, and multiple shifts are rotated. The cleaning fluid, clean water and cleaning tools carried in one climbing are reused. Manual climbing operations are characterized by high danger, high labor intensity, long operation time and unclean cleaning. Some operations that require non-stop power supply are mostly washed manually with high-pressure distilled water or dry ice, which also requires multiple people to work, consumes a large amount of distilled water or dry ice, and some professionally designed small cleaning robots are inconvenient to use, low cleaning efficiency and troublesome maintenance, and none of them have been mass-produced.
