Insulator sweeping device

Abstract

The invention discloses an insulator sweeping device. The insulator sweeping device comprises a first sweeping and dirt removing mechanism and a second sweeping and dirt removing mechanism which are symmetrically arranged, the first sweeping and dirt removing mechanism and the second sweeping and dirt removing mechanism comprise approximate arc-shaped sweeping and dirt removing machine frames, atleast one pair of arc-shaped connecting arms are arranged on each of the two sides of each sweeping and dirt removing machine frame in an extending mode, a permanent magnet attracting disc is arrangedat a free end of each arc-shaped connecting arm of the first sweeping and dirt removing mechanism, a plurality of travelling devices are arranged on the inner walls of the sweeping and dirt removingmachine frames, the inner walls of the sweeping and dirt removing machine frames are also provided with arc-shaped gear rings and gear ring driving mechanisms for driving the arc-shaped gear rings torotate in a reciprocating mode, and sweeping devices are arranged on the inner walls of the arc-shaped gear rings. According to the insulator sweeping device, sweeping and dirt removing procedures such as up-down travelling and sweeping can be safely and efficiently and automatically completed, high-altitude manual sweeping is replaced, the working safety is improved, the travelling devices and the sweeping devices can be adapted to insulator pieces with different diameters, and the adjusting mode is simple and convenient.

Description

technical field [0001] The invention relates to the technical field of insulator cleaning equipment, in particular to an insulator cleaning device. Background technique [0002] With the promotion of the Global Energy Internet, UHV AC and DC are developing rapidly, and the national power grid has entered the era of UHV. Cause flashover, and even lead to DC outage, causing heavy losses. Therefore, the cleaning and decontamination of insulators has become the top priority of the power outage maintenance of the converter station. The traditional cleaning method mainly relies on a large number of manpower and tools, and the operators take aerial vehicles Using rags for manual cleaning has many disadvantages such as unclean cleaning, low work safety factor, and low work efficiency. [0003] At present, there are several mechanical devices for automatic cleaning of insulators in converter stations on the market. For example, a Chinese invention patent application (application pub...

Problems solved by technology

However, the common problem of these cleaning equipment is that due to the defects of the design structure and cleaning method, the upper and lower surfaces of the insulator cannot be completely cleaned during the cleaning operation, and the cleaning brush can only touch the position of the insulator sheet away from the axis. Incomplete cleaning, poor cleaning effect
