Description

Technical Field

[0001] The utility model belongs to the technical field of railway insulator water flushing, and in particular relates to a high-vacuum double-layer heating and heat-insulating transport tank of an insulator flushing vehicle under extremely cold working conditions. Background Art

[0002] Contact network insulators are key components used to isolate current-carrying conductors and support power supply lines in rail transit electrical systems. Due to the dust dispersed in the air and the dust particles stirred up by the fast-moving train, a large amount of dirt will be deposited on the surface of the insulators that are exposed for a long time, reducing the insulation effect and even causing flashover accidents, which seriously threatens the safety of railway transportation. Using an insulator flushing vehicle to flush insulators is one of the current mainstream insulator cleaning methods. However, under the extremely cold weather conditions in northern my country in winter, the dirt on the surface of the insulator condenses with rain and snow and adheres to the surface of the insulator. The conventional flushing vehicle cold water flushing method is difficult to complete the flushing task, and even the flushing water condenses into ice due to the low temperature outside, which makes the flushing vehicle unable to operate. In order to reduce the impact of low temperature outside, the insulator flushing vehicle generally uses hot water flushing to operate. At this time, the thermal insulation performance of the flushing water transport tank directly affects the quality of insulator flushing.

[0003] At present, although some insulated transport tanks have appeared in the market, which have a certain insulation effect, for the working conditions of insulator washing vehicles, conventional insulated transport tanks lose heat quickly and have a short insulation time under extremely cold weather conditions, which makes it difficult to meet the needs of the long operation time of insulator washing vehicles. Therefore, improving the insulation performance of transport tanks and extending the insulation time are crucial to ensure the quality and efficiency of insulator washing vehicle washing operations under extremely cold weather conditions.
