[0002] Overhead transmission lines, commonly referred to as "overhead lines", are the most common and critical power transmission carriers in power systems. They are networks that use open-air towers or poles to support insulator strings and bare conductive lines in the air to achieve long-distance and large-capacity transmission of electric energy. The core of the line is usually composed of a steel core wrapped in multiple aluminum strands (or aluminum alloy strands) (referred to as steel-cored aluminum strands), which simultaneously serves as a conductor and a mechanical strength. In the West-to-East Power Transmission Project, a large number of overhead lines are located in high-altitude areas with large diurnal temperature differences.

[0024] The working principle and use process of the application are as follows: first, the overhead line between the two iron towers is not completely tight, so that the overhead line will exist certain shaking, at this time, the reducing resistance pulley 211 will shrink in volume due to cold shrinkage in relatively cold weather, at this time, the sliding ring groove plate 208 will continuously slide outside the inner support pipe 203 when the cable shakes, at this time, the reducing resistance pulley 211 in the inner side of the rotating groove 209 will cold shrink to the position where the outer arc surface is tangent to the support ring plate 202, then the reducing resistance pulley 211 will rotate outside the rotating shaft 210, so as to assist the sliding ring groove plate 208 to slide inside the support ring plate 202, with the continuous sliding of the sliding ring groove plate 208 outside the inner support pipe 203, a certain amount of heat is generated, at this time, the heat generated between the sliding ring groove plate 208 and the metal sleeve pipe 201 is transmitted outward, so as to transmit the heat to the whole metal sleeve pipe 201 through the support ring plate 202, and then transmit the heat to the outer insulating protective layer 1 through the metal sleeve pipe 201, because the metal has good heat conductivity, the heat is evenly distributed to the whole overhead line through the metal sleeve pipe 201, at this time, the heat generated by friction can be transmitted to the outer insulating protective layer 1 through the metal sleeve pipe 201, so as to melt the snow outside the outer insulating protective layer 1, preventing the rain and snow from icing on the outside of the overhead line; With the continuous shaking of the sliding ring groove plate 208, a part of the heat is also transmitted to the inner heat preservation sleeve pipe 206, so as to prevent the brittle fracture of the heat preservation sleeve pipe 206 caused by overcooling, further ensuring the stable operation of the cable, after the temperature rises after cold weather, the reducing resistance pulley 211 will expand in volume under the action of thermal expansion, at this time, when the sliding ring groove plate 208 slides to the position of the positioning clamping groove 212, it will be clamped into the inner side of the positioning clamping groove 212, so as to fix the sliding ring groove plate 208, preventing the temperature generated by friction from continuously heating the overhead line, and ensuring the use stability of the overhead line; And when the overhead line shakes, the support cable 205 inside the plurality of connecting slots 204 can support the overhead line, so as to ensure the strength of the cable, and also prevent the overhead line from being broken by high-intensity snow in snowy weather; Subsequently, in some areas with perennial snow, the mounting frame 301 is connected with the iron tower when the overhead line is installed, then the overhead line passes through the sliding ring groove plate 208, and then abuts against the outer side of the pushing wheel 305 and then passes through the sliding ring groove plate 208 on the top of the rear fixed wheel 310, the hydraulic rod 303 is stretched to a suitable length, at this time, the telescopic rod 306 drives the rotating groove plate 304 and the pushing wheel 305 to move downward to support the overhead line, then the other end of the overhead line is connected with the cable of another iron tower; After the ice shell covers the outer surface of the overhead line, the hydraulic rod 303 can be controlled to retract, thereby driving the telescopic rod 306 and the rotating groove plate 304 to retract. At this time, the suspended part of the overhead line will deform and fall downward under the action of gravity. At this time, the ice shell on the outer surface of the outer insulation protection layer 1 will automatically break and peel off, thereby completing the rapid ice melting of the overhead line. After the ice shell falls off, the hydraulic rod 303 is again extended outward to a suitable length. The telescopic rod 306 drives the rotating groove plate 304 and the pushing wheel 305 to move downward, thereby supporting and resetting the overhead line, thereby ensuring the rapid fixing of the overhead line and further ensuring the stable use of the cable. Finally, when there is continuous snowfall in the local area, the operator can clamp the top fixing shell 401 at the top position outside the outer insulation protection layer 1 before the snowfall, and then align the bottom fixing shell 402 with the top fixing shell 401. At this time, the top connecting plate 403 and the bottom connecting plate 404 will be attached to each other. Then the operator tightens the connecting screw 405 on the inner side of the top connecting plate 403 and the bottom connecting plate 404, thereby fixing the top fixing shell 401 and the bottom fixing shell 402 outside the outer insulation protection layer 1. At this time, the driven roller 407 and the side drive roller 409 will be attached to the outer side position of the outer insulation protection layer 1. After the snowfall starts, the drive motor 410 inside the two motor grooves 408 is started. At this time, the drive motor 410 drives one of the side drive rollers 409 to rotate, thereby driving the top fixing shell 401 and the bottom fixing shell 402 to move outside the outer insulation protection layer 1, thereby driving the snow removal sleeve 411 to move outside the outer insulation protection layer 1. Then the snow removal sleeve 411 can remove the snow on the outer surface of the outer insulation protection layer 1 to prevent snow accumulation, thereby preventing snow water from freezing into ice shell and freezing on the outer side of the outer insulation protection layer 1, and further protecting the cable to prevent the cable from being damaged due to brittleness. Furthermore, in the area where the snow removal sleeve 411 has not reached, if an ice shell has been formed, the pressing plate 415 will continuously rotate downward outside the positioning column 414 through the adjusting rotating groove 416 under the pulling action of the ice breaking spring 419, thereby continuously attaching and pressing on the outer side of the outer insulation protection layer 1. Then, when the snow removal sleeve 411 passes, the thin ice shell remaining on the outer surface of the outer insulation protection layer 1 will be crushed and peeled off by the ice crushing stick 418, thereby preventing the ice shell from damaging the cable and further ensuring the ice melting efficiency of the cable.
