A transmission line deicing device

Abstract

The invention discloses a deicing device for a power transmission line. The deicing device comprises a main frame body. The main frame body comprises a first longitudinal beam, a second longitudinal beam and a third longitudinal beam. The first longitudinal beam and the second longitudinal beam are respectively provided with hook units. Each hook unit comprises a first hook assembly and a second hook assembly, wherein the first hook assembly and the second hook assembly can slide back and forth along the first longitudinal beam. The first hook assembly and the second hook assembly are opposite to each other. A power unit is arranged between the first longitudinal beam and the second longitudinal beam, and between the second longitudinal beam and the third longitudinal beam, respectively. The power unit can drive a third roller to walk along the power transmission line. A U-shaped fixing frame is arranged on the second longitudinal beam. A tensioning unit is arranged on the U-shaped fixing frame. The power transmission line can be bent at the fourth roller of the tensioning unit through the tensioning unit. According to the device, the characteristics that the ice is brittle and hard can be utilized. An ice layer on the surface of the power transmission line is broken through the local bending of the power transmission line. Therefore, the insulation layer of the power transmission line is prevented from being damaged.

Description

technical field [0001] The invention relates to the technical field of electric facility maintenance, in particular to a power transmission line deicing device. Background technique [0002] High-voltage transmission line is an important part of the power system. It not only bears the heavy responsibility of power transmission, but also its safety and reliability are directly related to the stable development of the national economy. In northern my country, when snow falls in winter, power transmission lines are threatened. Severe icing will cause grounding short circuit, disconnection, and even tower collapse accidents, which are extremely harmful. The traditional deicing methods are mainly manual operations, such as beating with bamboo poles, wooden sticks, ice picks, etc. These methods are not only difficult, time-consuming and laborious to deicing, but also the falling snow or ice can easily injure the staff and cause accidents harm. [0003] In response to this probl...

Severe icing will cause grounding short circuit, disconnection, and even tower collapse accidents, which are extremely harmful

The traditional deicing methods are mainly manual operations, such as beating with bamboo poles, wooden sticks, ice picks, etc. These methods are not only difficult, time-consuming and laborious to deicing, but also the falling snow or ice can easily injure the staff and cause accidents harm

[0003] In response to this problem, people have invented deicing robots, but most of the deicing robots use ice knives or set sharp objects on the rollers to crush the ice. Although this method can remove the ice on the surface of the power line, it cannot There is also the danger of destroying the insulation layer on the surface of the transmission line, and the damage to the insulation layer on the surface of the transmission line at one end will bring more serious consequences
