[0002] High-voltage overhead lines are a common type of power transmission facility, mainly composed of conductors, towers, insulators, foundations, and grounding devices. They can transmit electrical energy over distances of hundreds of kilometers, meeting long-distance power transmission needs and carrying large volumes of electricity. As a crucial component of the power grid, it is essential to strengthen inspections and maintenance before and after severe weather to promptly address potential hazards and prevent faults. High-voltage overhead lines play a vital role in modern society's power supply, especially after periods of cold winds and heavy snow, when their outer surfaces can freeze over with ice.

[0003] However, existing high-voltage overhead lines are relatively smooth after ice forms on their surface, making it difficult for maintenance personnel to stand. As a result, the ice shell on the surface of the high-voltage overhead lines is difficult to remove quickly, and prolonged freezing can easily damage the overhead lines. In order to avoid the above-mentioned technical problems, it is indeed necessary to provide a high-voltage overhead line that can be cleared of obstacles to overcome the defects in the existing technology.

There are two support frames 202 welded on each other. The two support frames 202 are symmetrically welded to the outside of the sliding tube 201 to facilitate clamping the cable.

[0032] A limit rod 206 is welded to the top of the rotating trough plate 203 at the corresponding position of the clamping trough plate 204. A limit nut 207 is threadedly connected to the outer side of the limit rod 206. A rotating rod 208 is rotatably mounted on the inner side of the rotating trough plate 203. A squeezing roller 209 is sleeved on the outer side of the rotating rod 208. The transmission end of the drive motor 205 is connected to the squeezing roller 209. The input end of the drive motor 205 is electrically connected to the output end of the counterweight battery box 213, which facilitates rapid de-icing. A squeezing column 210 is provided on the side, and a movable groove is opened on the inner side of the rotating groove plate 203. The squeezing roller 209 is rotatably connected to the squeezing roller 209 through the movable groove. Several squeezing columns 210 are provided, and the several squeezing columns 210 are equidistantly arranged on the outer side of the squeezing roller 209, which is conducive to crushing the ice shell.

A counterweight battery box 213 is installed at the bottom of the connecting frame 212.

[0033] A support component 3 is installed on the inner side of the overhead line protective sleeve 1;

[0034] Support component 3 includes an installation rubber layer 301, a receiving steel cable 302, a snap-fit ​​groove 303, a filling rubber 304, and a battery cell 305;

[0035] An installation rubber layer 301 is embedded inside the overhead line protective sleeve 1. A receiving steel cable 302 is snapped into the inner side of the installation rubber layer 301. Several receiving steel cables 302 are provided, and the several receiving steel cables 302 are embedded at equal angles inside the installation rubber layer 301, which helps to increase the stability of the cable. The inner side of the installation rubber layer 301 has a snap-fit ​​groove 303. A filling rubber 304 is embedded inside the snap-fit ​​groove 303. A battery cell 305 is embedded inside the filling rubber 304.

[0036] The working principle and usage process of this utility model are as follows: First, the sliding tube 201 is sleeved on the outside of the overhead line protective sleeve 1. Then, the connecting frame 212 and the counterweight battery box 213 are installed at the bottom of the outside of the sliding tube 201 by screws. At this time, the rotating groove plate 203 is rotated on the inside of the support frame 202 according to the diameter of the overhead line protective sleeve 1. The rotating groove plate 203 can be moved to drive the extrusion roller 209 to move. The extrusion column 210 can be attached to the outside of the overhead line protective sleeve 1. After the extrusion columns 210 on both sides are attached to the outside of the overhead line protective sleeve 1, the limiting nut 207 is tightened on the outside of the limiting rod 206. The two rotating groove plates 203 can be fixed by the limiting nut 207 and the clamping groove plate 204. The extrusion roller 209 can be fixed at this time.

[0037] By attaching the extrusion roller 209 to the outside of the overhead line protection sleeve 1, when the outside of the overhead line protection sleeve 1 freezes due to wind and snow, an ice shell will form on the outside of the overhead line protection sleeve 1. At this time, the drive motor 205 is turned on, which can drive the rotating rod 208 to rotate. In turn, the rotating rod 208 can drive the extrusion roller 209 and the extrusion column 210 to rotate. At this time, the two extrusion rollers 209 will crush the ice shell and drive the sliding tube 201 to slide on the outside of the overhead line protection sleeve 1. At this time, the peeling scraper 211 can peel off the external ice fragments, thereby preventing the ice shell from freezing and damaging the cable and ensuring the stability of power transmission.

[0038] Finally, when the cable is in use, all the supporting steel cables 302 inside the rubber layer 301 will support the cable, and the rubber layer 301 will deform to a certain extent when squeezed. At this time, when the extrusion column 210 squeezes, the extrusion pressure can be released to prevent the extrusion from damaging the battery cell 305 and ensure the safety of the cable. In addition, a certain distance is set between multiple battery cells 305 to ensure the heat dissipation efficiency of the cable and further improve the power transmission efficiency.
