A mechanical device for de-icing and obstacle removal that can span the cat's head tower of high-voltage lines

Abstract

A mechanical device for deicing and obstacle removal that can span the cat head tower of a high-voltage line. The present invention arranges obstacle-clearing clamping mechanisms (4) at both ends of the vehicle body (10), and further sets an obstacle-clearing clip at one end of the vehicle body The holding mechanism (1) and the obstacle-clearing mechanism (2) are installed on the vehicle body to clamp and overcome the obstacle mechanism (7), that is, the walking mechanism. The cat head tower in the middle realizes the automatic deicing and inspection and clearing of multi-speed lines, greatly improving its application range. The invention has the characteristics of simple structure and different use.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of deicing of high-voltage transmission lines, in particular to a mechanical device for deicing and obstacle removal that can span high-voltage line cat head towers. [0003] 【Background technique】 [0004] It is known that with the rapid development of my country's economy, more and more ultra-high-voltage large-capacity transmission lines are being built, and the geographical environment that the line corridor passes through is becoming more and more complex, such as passing through large-scale reservoirs, lakes and mountains, which brings great challenges to line maintenance. Come a lot of difficulties. Especially in severe winter and early spring, smog and smog often appear in the Yunnan-Guizhou Plateau, Sichuan-Shaanxi area, and the two lakes in my country, causing icing on overhead transmission lines, causing lines to dance, flashover, burns, and even broken lines and inverted poles, causing the power gri...

Problems solved by technology

These insulating barriers will not cause any harm to the high-voltage lines during the day and sunny days. In the evening, when the cold air increases at night, these lightweight barriers will be atomized into water droplets, and the accumulation of water droplets will make these insulating barriers Lightweight obstacles become conductors, if they cannot be removed in time, they will seriously endanger the normal supply of high-voltage lines

When these insulating obstacles become conductors, if they touch another wire of the high-voltage line, a short circuit will occur instantaneously, paralyzing the entire power supply system and seriously affecting normal production and life.

[0006] However, at present, the obstacles on the high-voltage line still rely on the traditional manual removal. Manual removal has high work intensity and high risk hazards. Therefore, it is particularly important to design a deicing and obstacle removal device that can replace the manual crossing of the cat head tower on the high-voltage line. Then How to provide a de-icing and obstacle-clearing mechanical device that can cross the cat head tower of the high-voltage line has become the technical demand of those skilled in the art.
