Problems solved by technology

The overloaded gravity brought by severe line icing will break the transmission line, and even cause the tower to collapse, causing large-scale power interruptions and causing huge economic losses. In a word, icing accidents seriously threaten the safety of my country's power system run
[0003] At present, the risk elimination methods adopted are mainly to melt ice by heating on the power transmission line. Transmission lines), high-frequency excitation ice melting (using the skin effect of high-frequency high-voltage electricity, causing resistance loss and heat on the transmission line to melt ice), the use of ice-melting methods inevitably requires a certain degree of transformation of the transmission line , and it needs to consume a lot of energy for heating, and the cost and difficulty of deicing are high. Therefore, it is urgent to design a deicing device for power transmission lines to solve the above problems

Abstract

The invention discloses a deicing device for a power transmission line. The device comprises a lower fixed seat and an upper fixed seat, the lower fixed seat and the upper fixed seat are rotatingly connected through a hinge, a buckle on the upper fixed seat is buckled with a clamping seat on the lower fixed seat, the outer wall of the top of the lower fixed seat is provided with a mounting groove,a limiting groove is formed in the inner wall of the bottom of the mounting groove, a sliding rod is slidably connected with the inner wall of the limiting groove, a lug seat is fixedly connected with the outer wall of the top of the sliding rod, a roller is rotatably connected with the inner wall of the lug seat through a bearing, a first spring is fixedly arranged on the inner wall of the bottom of the mounting groove, one end of the first spring is fixedly connected with the outer wall of the bottom of the lug seat, and a fixing groove is formed in the outer wall of the bottom of the upperfixed seat. According to the invention, the driving wheel and the roller can clamp power transmission lines with different thicknesses, the use is more flexible, automatic deicing is realized, manualbeating is not needed, and the deicing effect is better.

Description

technical field [0001] The invention relates to the technical field of power transmission line maintenance, in particular to a deicing device for power transmission lines. Background technique [0002] Transmission lines play an important role in the transmission of electricity. Ensuring the safe and reliable operation of transmission lines is of great significance to ensuring the stable and healthy development of the national economy. Occurrence of icing on the surface. The overloaded gravity brought by severe line icing will break the transmission line, and even cause the tower to collapse, causing large-scale power interruptions and causing huge economic losses. In a word, icing accidents seriously threaten the safety of my country's power system run. [0003] At present, the risk elimination methods adopted are mainly to melt ice by heating on the power transmission line. Transmission lines), high-frequency excitation ice melting (using the skin effect of high-frequenc...
