Description

A catenary insulator cleaning device

technical field

The utility model relates to the technical field of the electric power industry, in particular to a cleaning device for a catenary insulator.

Background technique

There are two main types of cleaning methods for insulators: one is contact cleaning; the other is water flush cleaning.

The earliest contact cleaning is manual wiping. This method has good cleaning effect, low technical requirements and is the most widely used. However, it is gradually eliminated due to its large workload, high labor intensity, complicated operation, low cleaning efficiency and low safety factor. In order to improve the safety factor and reduce labor intensity, a long-arm insulator semi-automatic cleaning brush is designed. The cleaning brush consists of two rotatable brush heads and two insulating rods. The cleaning is realized by the friction between the brush head and the insulator; The brush rod is used for aiming, and the operation is relatively cumbersome. With the progress of science, a series of contact cleaning robots have been designed at home and abroad, with high degree of automation, good cleaning effect, and no manual intervention, but the cost is too high, and it is difficult to achieve large-scale promotion.

Water-flushing cleaning is to directly impact the dirty insulators through high-pressure water jets to achieve the purpose of cleaning; in addition, the use of various cleaning agents improves the cleaning effect, and the replacement of spray guns enhances its applicability, and its application fields are becoming wider and wider. . Water-flushing cleaning includes close-range cleaning, long-distance cleaning, and water cannons. Among them, high-pressure cleaners are the most widely used. During the cleaning process, workers stand on the working platform of the rail maintenance vehicle and hold the spray gun at the insulator for cleaning. This method Although the cleaning efficiency is high, it still requires too much manual intervention; long-distance cleaning is similar to short-distance cleaning, but the spray distance of the water jet is longer, the impact force is greater, and the concentration is better. The efficiency is high, but it still requires manual hand-held water guns to aim, which is difficult to operate and wastes water resources seriously.

In order to solve the pollution flashover problem of catenary insulators, the railway bureaus and power supply sections invest a lot of manpower, material resources and financial resources to clean the insulators manually every year, but the results are uneven, which greatly increases the labor intensity of the staff and takes up contact. In order to solve the above technical problems, the utility model provides a catenary insulator cleaning device, which has the advantages of small size, high working reliability and high cleaning efficiency.
