A 500kv transmission line high-altitude patrol robot anti-environmental interference method

Abstract

The invention discloses an anti-environmental interference method for a 500KV transmission line high-altitude line inspection robot. An anti-environmental interference device is provided. The anti-environmental interference device includes a shield, a flamethrower and a windshield. Tank, air pump, oxyhydrogen gas injection nozzle, electronic igniter, shroud including thermal insulation ceramic and metal sleeve. The invention can solve the impact of high-altitude line inspection robots encountering environmental debris when patrolling the line, provide abnormally high-temperature flames, ensure that the environmental debris is interrupted and burned, and no residue is left, and at the same time, the high-temperature flame has no direct impact on the transmission line , In order to solve the faults, defects and hidden dangers of the transmission line, and reliably deal with the foreign matter on the surface of the transmission line to establish a meritorious service.

Description

technical field [0001] The invention relates to the field of line inspection robots, in particular to an anti-environmental interference method for a 500KV transmission line high-altitude line inspection robot. Background technique [0002] At present, the power transmission institute has jurisdiction over more than 6,000 kilometers of overhead transmission lines, and new lines are continuously put into operation every year. Overhead transmission lines cover a wide area and cross areas with complex terrain. In addition, the ground wire part of the overhead line is high from the ground, and the wire diameter is relatively small, and the existing defects or hidden dangers are not easy to find. This method is not only labor-intensive, but also time-consuming and inefficient. Some line sections are restricted by terrain factors and cannot even be inspected. Even in the inspection of drones, there are dead spots for inspection. In recent years, some overhead ground wires have b...

Problems solved by technology

[0005] In the process of a large number of line inspections, there are also a large number of environmental debris interference sources, which seriously affect the life and safety of the transmission line, such as various debris brought by the wind, resulting in galvanic corrosion, mechanical hidden dangers, and accidental electric shock discharge Danger, etc., because the 500KV transmission line is high from the ground, the hidden objects that can be attached include light and thin iron sheets, films, braids, cables, branches and weeds and other stubborn obstacles that are easy to entangle, and the rain and snow continue to freeze and accumulate thickness Exceeding the limit, etc., using a knife to cut, the efficiency is low, and the effect is not good. It is difficult to burn clean with oil flames, especially for metal wires, iron sheets, etc., and it is the same as the residue after burning. The main interference source of transmission line corrosion, the use of hydrogen-oxygen flame or acetylene flame with a temperature of up to 3000 degrees Celsius can indeed completely remove foreign matter, but if the interference source is directly incinerated, the high-temperature flame has to heat the transmission line at the same time It is very hot, and there are fuses on the transmission line, which will cause the transmission line to be softened by heat, chemical oxidation, mechanical performance degradation, tensile deformation and other defects, which will seriously reduce the life of the transmission line. High-temperature flames can ensure blowing, burning and leaving no residue, and it is necessary to minimize the direct impact of flames on power transmission lines.
