Description

Technical Field

[0001] This invention relates to the field of power cable technology, specifically to a high-voltage power de-icing type overhead line. Background Technology

[0002] Overhead transmission lines, commonly referred to simply as "overhead lines," are the most common and critical carriers of electrical energy transmission in power systems. They refer to networks that use open-air iron towers or poles to support insulator strings and exposed conductive lines, enabling long-distance, high-capacity transmission of electrical energy. The core of the line is usually composed of multiple strands of aluminum stranded wire (or aluminum alloy stranded wire) wrapped around a steel core (called steel-cored aluminum stranded wire), which serves both conductive and mechanical strength purposes. 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. In cold weather, the surface of the overhead lines will be covered with a layer of ice, which is usually removed manually. Chinese patent application number 202010805980.8 discloses "A High-Temperature Resistant Carbon Fiber Core Optoelectronic Composite Overhead Conductor." This patent uses two layers of trapezoidal soft aluminum wire symmetrically arranged between single-mode fiber units and multimode fiber units. The high-temperature resistant carbon fiber core optoelectronic composite overhead conductor of this invention is used to improve the comprehensive performance of composite conductors.

[0003] However, most existing overhead lines directly break the ice shell, which causes the overhead lines to be subjected to great pressure. This not only results in low ice-breaking efficiency but also easily damages the overhead lines, making it unprofitable and difficult to melt the ice quickly. To avoid the above-mentioned technical problems, it is indeed necessary to provide a high-voltage power ice-melting overhead line to overcome the defects in the existing technology.

[0028] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use.

[0029] 1. Equipped with a temperature control component, the heat generated between the sliding ring groove plate and the metal bushing is transferred outward, and then transferred to the entire metal bushing through the support ring plate. Subsequently, the heat is transferred to the outer insulation protective layer. Because metal has good thermal conductivity, this heat will be evenly distributed to the entire overhead line through the metal bushing. At this time, the heat generated by friction can be transferred to the outer insulation protective layer through the metal bushing, thereby melting the snowfall outside the outer insulation protective layer and preventing the rain and snow from freezing and covering the outside of the overhead line.

[0030] 2. A retraction assembly is provided to control the retraction of the hydraulic rod, which in turn drives the telescopic rod and rotating slot plate to retract. At this time, under the action of gravity, the suspended part of the overhead line will deform and fall downward. At this time, the ice shell on the outer surface of the outer insulation protective layer will automatically break and peel off, thereby completing the rapid melting of the ice on the overhead line. After the ice shell falls off, the hydraulic rod is opened and reset, thus ensuring the rapid fixation of the overhead line and further ensuring the stable use of the cable.

[0031] 3. Equipped with an anti-freeze component, starting two drive motors drives one of the side drive rollers to rotate, which in turn moves the snow-shoveling sleeve outside the outer insulation layer. The snow-shoveling sleeve then removes the snow from the outer surface of the outer insulation layer to prevent snow accumulation, thus preventing the snow water from freezing into an ice shell on the outer surface of the outer insulation layer. This further protects the cable from embrittlement and damage. Under the pulling action of the ice-crushing spring, the pressure plate continuously presses against the outer surface of the outer insulation layer. After the snow-shoveling sleeve passes, the thin ice shell remaining on the outer surface of the outer insulation layer is crushed and removed by the ice-crushing roller, thus preventing the ice shell from damaging the cable and further ensuring the cable's ice-melting efficiency.

[0065] The working principle and usage process of this invention are as follows: First, when using overhead lines, the overhead lines between two towers are not completely taut, resulting in some swaying. In colder weather, the drag-reducing pulley 211 shrinks due to thermal contraction. As the cable sways, the sliding ring groove plate 208 continuously slides on the outside of the inner support tube 203. At this time, the drag-reducing pulley 211 inside the rotating groove 209 shrinks until its outer arc surface is tangent to the support ring plate 202. The drag-reducing pulley 211 then rotates on the outside of the rotating shaft 210, thus assisting the sliding ring groove plate 208 in sliding on the inside of the support ring plate 202. As the sliding ring groove plate 208 slides continuously on the outside of the inner support tube 203, it generates a certain amount of heat. At this time, the heat generated between the sliding ring groove plate 208 and the metal sleeve 201 will be transferred outward, and then transferred to the entire metal sleeve 201 through the support ring plate 202. Subsequently, the heat is transferred to the outer insulation protection layer 1 through the metal sleeve 201. Because metal has good thermal conductivity, this heat will be evenly distributed to the entire overhead line through the metal sleeve 201. At this time, the heat generated by friction can be transferred to the outer insulation protection layer 1 through the metal sleeve 201, thereby melting the snowfall outside the outer insulation protection layer 1 and preventing the rain and snow from freezing and covering the outside of the overhead line.

[0066] As the sliding ring groove plate 208 continues to shake, some heat will be transferred to the internal insulation sleeve 206, thus preventing the insulation sleeve 206 from becoming brittle and breaking due to overcooling, and further ensuring the stable operation of the cable. When the temperature rises after cold weather, the drag-reducing pulley 211 will expand slightly due to thermal expansion. At this time, when the sliding ring groove plate 208 slides to the position of the positioning slot 212, it will be locked into the inner side of the positioning slot 212, thereby fixing the sliding ring groove plate 208, thus preventing the temperature generated by friction from continuing to heat the overhead line, and ensuring the stability of the overhead line in use.

[0067] Furthermore, when the overhead line sways, the support cables 205 inside the multiple connection slots 204 will support the overhead line, thereby ensuring the strength of the cable and preventing the overhead line from being broken by heavy snowfall in heavy snow weather.

[0068] Subsequently, in some areas with heavy snowfall year-round, when installing overhead lines, the mounting bracket 301 is connected to the tower. Then, the overhead line is passed through the sliding ring groove plate 208, then pressed against the outside of the push wheel 305, and then passed through the sliding ring groove plate 208 on the top of the rear fixed wheel 310. The hydraulic rod 303 is extended outward to a suitable length. At this time, the telescopic rod 306 will drive the rotating groove plate 304 and the push wheel 305 to move downward to open the overhead line. Then, the other end of the overhead line is connected to the cable of another tower.

[0069] After the ice shell is covered on 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 trough plate 304 to retract. At this time, under the action of gravity, the suspended part of the overhead line will deform and fall downward. At this time, the ice shell on the outer surface of the outer insulation protective layer 1 will automatically break and peel off, thereby completing the rapid melting of the ice shell on the overhead line. After the ice shell falls off, the hydraulic rod 303 is extended outward again to a suitable length. The telescopic rod 306 will drive the rotating trough plate 304 and the push wheel 305 to move downward to open and reset the overhead line, thereby ensuring the rapid fixation of the overhead line and further ensuring the stable use of the cable.

[0070] Finally, when there is continuous snowfall in the local area, the operator can clip the top fixing shell 401 onto the top position of the outer side of the outer insulation protective layer 1 before the snowfall. 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 fit together. Then, the operator will tighten 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 on the outer side of the outer insulation protective layer 1. At this time, the driven roller 407 and the side drive roller 409 will fit against the outer side of the outer insulation protective layer 1.

[0071] After the snowfall begins, the drive motors 410 inside the two motor slots 408 are started. At this time, the drive motors 410 will drive one of the side drive rollers 409 to rotate, thereby driving the top fixed shell 401 and the bottom fixed shell 402 to move outside the outer insulation protective layer 1. This will drive the snow-shoveling sleeve 411 to move outside the outer insulation protective layer 1. Subsequently, the snow-shoveling sleeve 411 can remove the snow on the outer surface of the outer insulation protective layer 1 to prevent snow accumulation, thereby preventing the snow water from freezing into an ice shell on the outside of the outer insulation protective layer 1, further protecting the cable from embrittlement and damage.

[0072] Furthermore, if an ice shell has already formed in the area not reached by the snowplow sleeve 411, the pressing plate 415 will continuously rotate downwards outside the positioning post 414 through the adjusting groove 416 under the pulling action of the ice crushing spring 419, thereby continuously pressing against the outer side of the outer insulation protective layer 1. Subsequently, after the snowplow sleeve 411 passes, the thin ice shell remaining on the outer surface of the outer insulation protective layer 1 will be crushed and removed by the ice pressing rod 418, thereby preventing the ice shell from damaging the cable and further ensuring the ice melting efficiency of the cable.
