Abstract

The live insulator cleaning apparatus consists of an insulated vehicular elevating mechanism, a reducing motor, an insulated telescopic rotating rod, a swinging mechanism and a cleaning head. During operation, the cleaning head is first inserted into the neck of the insulator, the reducing motor is then powered to rotate the telescopic rotating rod and oscillate the swinging mechanism so as to oscillate the cleaning head sweeping away dust. One blower may be increased to even raise the cleaning effect. The present invention is safe and fast in cleaning speed, and cleaning the insulator can avoid dirt discharging.

Description

Live insulator cleaning apparatus

Technical field

The present invention relates to a kind of device that rod in the charging operation (post) t shore insulator surface is cleaned, belong to the power equipment safety running technology field that guarantees.

Background technology

In transformer station, the surface of the rod in the electrical equipment charging operation (post) t shore insulator is its skirt section particularly, because the long-time pollution of atmosphere, so that accumulate a large amount of filthy materials, can cause filthy discharge accident, so need often clean, predetermined distance must not be above 1 year.For the pure remote directly method of flushed zone electric(al) insulator of water of earning of theoretic available high pressure, big owing to water consumption, expense is high, the degree of purity of water be difficult for to guarantee and equipment is intensive is difficult to satisfy the remote reason such as needs of spraying, careless slightlyly go back the entail dangers to personal safety, do not see that so far the someone dares to use.Existing cleaning scheme is still hand sweeping mainly, promptly scaffolding erecting respectively, it is neighbouring with rag or hairbrush cleaning to climb to insulator, though this scheme is simple, but waste time and energy very much, and must after having a power failure, just can carry out, have a strong impact on normal power supply, tend to have a power failure on time because the user needs, cause the phenomenon ubiquity that surpasses cleaning blanking time to insulator more than a year, make power equipment have great potential safety hazard.It is a global problem of failing the headache of the domestic and international power department of making of fine solution so far.

Summary of the invention

Purpose of the present invention mainly be for the rod in the transformer station (post) t shore insulator design a kind of rational in infrastructure, safe and reliable, easy to use, mechanization degree is high, can replace the artificial live insulator cleaning apparatus that directly wiping is carried out in the serious skirt section of insulator especially incrustation.
