Description

Technical Field

[0001] The utility model relates to the field of electric power operation and maintenance, in particular to a wire deicing device. Background Art

[0002] Power operation and maintenance refers to the maintenance of power lines, power operations, and power emergency repairs. In the cold winter, when the air humidity is high, the surface of the transmission line is very prone to ice formation, and as the temperature continues to drop, the amount of ice on the surface of the transmission line will gradually increase, causing the weight load of the transmission line to become heavier and even leading to serious consequences such as the transmission line being broken and the tower collapsing, posing a huge safety hazard.

[0003] After searching the patent document with the announcement number CN219678076U, the patent document discloses "a deicing device for operation and maintenance of power transmission lines, in which the driving unit and the transmission mechanism of the device cooperate with each other, and the installation roller rotates and cooperates with the tension wheel to move the bottom box and the top box. At the same time, the ice scraper can rotate to scrape the ice covered on the wire, thereby reducing the use of energy. With the action of the stopper, the ice scraper plate rotates to scrape off the covered ice, and the deicing efficiency is high without damaging the wire. Combined with the action of the frosting plate, the residual ice layer on the wire can be further scraped off, ensuring the deicing effect while being more energy-saving";

[0004] However, the wires or cables are designed according to the needs, so the cross-sectional diameters of the wires or cables will be different. When the above-mentioned device is in operation, since the sizes of the rotating plate, ice scraper plate, block and frosting plate are fixed, it is difficult for the device to de-ice wires or cables of other sizes, resulting in poor applicability of the device.
