Combined automatic dirt removing device of medium-lower-voltage power grid overhead line

Abstract

The invention relates to a combined automatic dirt removing device of a medium-lower-voltage power grid overhead line. The combined automatic dirt removing device is technically characterized in that the device comprises a locking body, a travelling module, a reciprocating movement module, a dirt removing module and an obstacle removing module, a wire is sleeved with the modules with the dirt removing module as the center, the reciprocating movement module, the travelling module, the locking body and the obstacle removing module are symmetrically installed on the two sides of the dirt removing module, control modules are arranged in the locking body and the obstacle removing module, and a power source module is installed in the locking body and connected with the corresponding control module to supply power to the control module. The combined automatic dirt removing device is reasonable in design, peculiar matter wound on the wire can be effectively removed, dirt attached to the surface of the wire can also be removed, automatic dirt removing of the medium-lower-voltage power grid overhead line is achieved, unnecessary trouble caused by manual dirt removing is avoided, and the dirt removing efficiency is greatly improved.

Description

Technical field [0001] The invention relates to the field of power line maintenance, in particular to a combined automatic cleaning device for overhead lines of a medium and low voltage power grid. Background technique [0002] Electric power overhead lines are the main power transmission carrier used in today's power industry. According to the different voltage levels, it can be divided into many types. Among them, 10kv and below belong to the middle and low voltage level. The power overhead lines under this voltage level are mostly distributed in densely populated urban areas. In order to prevent electric shock and other safety considerations, power lines They are all designed in accordance with insulated wires. Because the line is exposed to this densely populated external environment for a long time, it is susceptible to external interference, such as wrapping plastic bags, kites, balloons, etc. on the line, or the line surface caused by industrial waste gas and dust generat...

AI Technical Summary

Problems solved by technology

Because the line is exposed to this densely populated external environment for a long time, it is easy to be disturbed by the outside world, such as plastic bags, kites, balloons, etc. wrapped around the line, or the surface of the line is damaged by industrial waste gas and dust generated by surrounding factories. A large amount of pollution is formed. These foreign objects can easily cause phase-to-phase short circuit in rainy weather, which may cause line tripping and power failure, which will cause great harm to the normal operation of the line, thus affecting normal production and life.

[0003] At present, people are constantly researching on the cleaning of power overhead lines. The Chinese patent document with the application number CN201420366887.1 discloses a power transmission line cleaning tool. On the electric
