Embodiment Construction

[0015] The best implementation mode of the present invention will be described below through specific implementation methods.

[0016] See figure 2 , the laser deicing machine is composed of a generator 1, a cable 2, a high-power laser 3, a launcher 4, a high-power sight 5, a reflector 6, a base 8, and an angle adjustment device 7 for linking the reflector 6 and the high-power sight 5 . The generator 1 is connected with the laser 3 through the cable 2 , the laser 3 and the launch frame 4 are installed on the base 8 , and the angle adjustment device 7 is fixed on the launch frame 4 . The angle adjustment device 7 can adjust the scope 5 and the reflector 6 in linkage, and the adjustment angle is 360 degrees in the horizontal direction and 0 to 90 degrees in the vertical direction. The generator 1 supplies power to the laser 3 through the cable 2, and the laser beam generated by the laser 3 is reflected by the mirror 6, and the laser beam 9 is irradiated to a designated positi...

Abstract

The invention relates to a novel process for cleaning ice or snow covering a transmission line and a laser de-icing machine. In the process, a high-power laser is adopted to lead the laser to irradiate an iron tower and a cable, the intense laser radiation heating is used to lead part of the ice and snow covering connection transmission line to be molten, and the rest of ice and snow fall onto the ground. The laser de-icing machine consists of a power generator, a laser, a reflective mirror, a high-power collimation mirror and a fine regulating device which links the reflective mirror and the collimation mirror, wherein the power generator is connected with the laser through a cable; the laser and a transmitting frame are arranged on a base; an angle regulating device is fixed on the transmitting frame; and the angle regulating device can regulate the collimation mirror and the reflective mirror through linkage. The novel process has the advantages of high speed for cleaning the ice and snow covering the high-voltage transmission line, labor-saving performance and good security.

Description

technical field [0001] The invention relates to the technical field of maintenance of high-voltage power grid lines, in particular to a new technology for removing ice and snow from transmission lines in winter and a laser deicer. Background technique [0002] When rain and snow come in winter in most parts of our country, removing ice and snow covering transmission lines is a common problem in the maintenance of high-voltage power grid lines. For example, in January 2008, the Yangtze River Basin experienced freezing rain and heavy snow that had not been encountered in 50 years. Many transmission lines, cables and towers were covered with ice and snow. On the morning of January 17, the tension-resistant section of the ±500 kV Yihua DC transmission line #1146-#1153 of the State Grid located in the hinterland of the Dabie Mountains was severely damaged and collapsed due to the heavy load of ice and snow, causing Widespread power outages caused huge losses. [0003] The curre...
