Problems solved by technology

[0002] Ice hanging disaster of high-altitude cables is one of the main factors affecting the safety of transmission lines in winter. The formation of ice hanging is caused by rain and snow falling on the cables, and the heat emitted by the cables melts the snow. The rain and snow on the cables cannot be Clear it in time. In continuous rainy and snowy weather, the speed at which rain and snow condense into ice is greater than the speed at which the cable melts ice and snow, thus forming ice hangs on the cable. When the weight of the ice hang exceeds the load-bearing weight of the cable, the cable will The phenomenon of collapse, resulting in the paralysis of transmission lines

Embodiment 1

[0038] Such as figure 1 As shown, a high-altitude cable maintenance device includes a moving component and a wiping component.

[0039] Such as figure 1 As shown, the moving components include active components and driven components. The active assembly includes a motor 1 and a driving wheel 2 . The casing of the motor 1 is fixed on the first cable rack through fasteners, and the driving wheel 2 is welded and fixed to the output shaft of the motor 1 . The driven assembly includes a driven wheel 3 , a driven shaft 4 and a driven wheel seat 5 . The driven wheel seat 5 is fixed on the second cable frame by fasteners, the two ends of the driven shaft 4 are welded and fixed with the driven wheel seat 5, the driven wheel 3 and the driven shaft 4 are clearance matched, and the driven wheel 3 can rotate around the driven wheel Axis 4 rotates. The driving wheel 2 and the driven wheel 3 are driven by a transmission belt 6 . In Embodiment 1, bolts or screws are used as fasteners, a...

Embodiment 2

[0058] Embodiment 2 is the same as Embodiment 1, except that it is in a high-altitude cable maintenance device of Embodiment 2.

[0059] Such as Figure 4 or Figure 5 As shown, both the first half cylinder 18 and the second half cylinder 19 are provided with an accommodating cavity 26 for containing a water-absorbent pad 25 . By arranging the receiving chamber 26, the first half cylinder 18 or the second half cylinder 19 and the absorbent pad 25 can be installed together only by inserting the absorbent pad 25 into the receiving chamber 26; The water-absorbing pad 25 on the first half-tube 18 or the second half-tube 19 can be removed by pulling out the cavity 26, so that the first half-tube 18 or the second half-tube 19 and the water-absorbing pad 25 can be disassembled quickly and easily. , easy to replace the absorbent pad 25, easy to maintain.

[0060] Such as image 3 As shown, the first half cylinder 18 is provided with a first squeeze hole 18 - 2 for communicating wi...

Embodiment 3

[0071] Embodiment 3 is the same as Embodiment 2, except that it is in a high-altitude cable maintenance device of Embodiment 3.

[0072] Such as figure 1 or image 3 As shown, the end of the first support plate 33 away from the first half cylinder 18 and the end of the second support plate 34 away from the second half cylinder 19 are welded and fixed with heating elements. In this embodiment 3, the heating element adopts an electric heating plate 31 , the surface of the electric heating plate 31 is coated with insulating paint.

[0073] Because the length of cable is longer, can reach 2 kilometers, so in the process that casing moves together with driving belt 6, water-absorbent pad 25 wipes cable, wraps up a layer of ice on the cable that has not been wiped by water-absorbent pad 25, So when the water-absorbing pad 25 is wiped on the cable that has been frozen, the wiping effect of the water-absorbing pad 25 on the cable is reduced. For this, it is necessary to start the el...

Abstract

The invention discloses a high-altitude cable maintenance device and relates to the technical field of cable maintenance. Including the wiping assembly, the wiping assembly includes a casing, a cylinder, and a water-absorbing pad arranged in sequence from outside to inside, the casing moves along the cable through the moving assembly, the inner cavity of the cylinder cooperates with the cable, the cylinder is connected with the casing, and absorbs water The pad is arranged between the cylinder and the cable, and the water-absorbing pad is connected with the cylinder. On the one hand, it can wipe off the snow or rain on the cable to prevent the snow or snow on the cable from condensing into ice, thereby avoiding the formation of cable ice hanging and preventing the cable from collapsing due to heavy ice hanging; on the other hand Aspects, the present invention is especially applicable to acid rain areas, such as my country's Southwest acid rain area, central China acid rain area, and East China coastal acid rain area. The acid rain and acid mist on the surface of the cable are wiped off to prevent acid rain or acid mist from flowing into the skin cracks of the cable. The metal layer in the cable skin causes corrosion and improves the protection effect of the cable.

Description

technical field [0001] The invention relates to the technical field of cable maintenance, in particular to a high-altitude cable maintenance device. Background technique [0002] Ice hanging disaster of high-altitude cables is one of the main factors affecting the safety of transmission lines in winter. The formation of ice hanging is caused by rain and snow falling on the cables, and the heat emitted by the cables melts the snow. The rain and snow on the cables cannot be Clear it in time. In continuous rainy and snowy weather, the speed at which rain and snow condense into ice is greater than the speed at which the cable melts ice and snow, thus forming ice hangs on the cable. When the weight of the ice hang exceeds the load-bearing weight of the cable, the cable will Collapse phenomenon, resulting in the paralysis of transmission lines. [0003] Therefore, how to wipe off the rain and snow on the cables and reduce the formation of ice hangs is an urgent problem to be solv...
