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. , 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 electric heating plate 31 in the process that the housing moves together with th...

Abstract

The invention discloses a high-altitude cable maintenance device, which relates to the technical field of cable maintenance. The device comprises a wiping assembly; the wiping assembly comprises a shell, a barrel and a water absorption pad which are sequentially arranged from outside to inside; the shell moves along a cable through a moving assembly; an inner cavity of the barrel is matched with the cable; the barrel is connected with the shell; the water absorption pad is arranged between the barrel and the cable; and the water absorption pad is connected with the barrel. On one hand, snow water or rainwater on the cable can be wiped off, the snow water or the snow water on the cable is prevented from being condensed into ice, and therefore the formation of cable ice hanging is avoided, and the situation that the cable is collapsed due to heavy ice hanging is avoided; and on the other hand, the device is especially suitable for acid rain areas, such as southwest acid rain areas, middle China acid rain areas and east China coastal acid rain areas, acid rain and acid mist on the surface of the cable are wiped off, the acid rain or the acid mist is prevented from flowing into surfacecracks of the cable to corrode a metal layer in the surface of the cable, and the protection effect on the cable is improved.

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...
