Abstract

The invention provides a periodic cleaning device for long-distance transmission lines, and relates to the technical field of transmission line cleaning equipment. The periodic cleaning device comprises a movable carrier, a storage bin arranged on the movable carrier, a suspension mechanism arranged on the storage bin, a spraying mechanism arranged on the movable carrier and a control mechanism which is arranged on the movable carrier and used for controlling the movable carrier, the suspension mechanism and the spraying mechanism. The periodic cleaning device can periodically clean the transmission lines in winter by adopting a special ice melting agent, and can realize the functions of patrol inspection and ice cleaning. In addition, the ice melting agent applicable to the ice melting device is provided, which is low in freezing point, high in ice melting speed in a short time, significant in ice melting effect and small in damage to carbon steel and plants.

Description

technical field [0001] The invention relates to the technical field of power transmission line cleaning equipment, in particular to a long-distance power transmission line regular cleaning device. Background technique [0002] With the development of the national power industry, the coverage area and density of the power supply grid are increasing, and the safety of the line has become inseparable from our daily life and work. After entering the winter, most parts of our country experienced rain, snow and freezing weather, and the power transmission and transformation facilities were damaged to varying degrees. In some areas, equipment tripping, disconnection and tower down accidents occurred, resulting in power outages in some areas. my country's transmission lines have suffered thousands of icing disasters in varying degrees. The icing of transmission lines will lead to accidents such as wire galloping, disconnection, tower collapse, insulator flashover, etc., which will ...
