Cable deicing device

Abstract

The invention discloses a cable deicing device. The deicing device comprises a deicing unit and a feeding unit, wherein the deicing unit comprises a deicing cutter which comprises a first cutter and asecond cutter which are used for horizontally breaking ice of a cable from two sides of the cable, a cam used for driving the first cutter and the second cutter to be away from the cable, and a deicing power assembly, wherein the deicing power assembly comprises a first energy storage spring and a second energy storage spring which are used for driving the first cutter and the second cutter to break ice respectively, the feeding unit comprises a walking pulley and a supporting pulley which are used for being placed at the top of the cable, the supporting pulley is provided with a working position used for being in rolling contact with the bottom of the cable and an initial position far away from the cable, and when the first cutter and the second cutter conduct icebreaking work on any position of the cable, the position of the deicing device on the cable is kept fixed. The cable deicing device is advantaged in that the cutters are used for effectively deicing the cable, deicing efficiency is high, safety is high, and the cable deicing device has a simple structure.

Description

technical field [0001] The invention relates to the technical field of cable deicing, in particular to a cable deicing device. Background technique [0002] The load-bearing capacity of the cable is limited. Once the load of the cable is too heavy, the line will be interrupted, thereby affecting the normal power demand. [0003] When the cold wave comes, it will often cause freezing rain. Rainwater below zero degrees Celsius will accumulate rime on the cable. The existence of these rime directly increases the load-bearing of the cable, and the rime attached to the cable will freeze after freezing. Icicles will gradually form, coupled with the shock caused by the wind and the impact of the weight of rime and icicles, it will cause the cables to exceed the load limit and break, which will not only cause large-scale power outages, but also easily lead to safety accidents. [0004] In order to avoid cable breakage due to accumulated rime and ice, it is often necessary to de-ice...

Problems solved by technology

[0005] Among them, for manual deicing, long-term cable deicing work will increase the safety risk of operators, and for long-distance cables, manual deicing operation is very difficult

[0006] Most of the existing cable deicing devices use heating to remove the ice on the cable, but the temperature is low in winter and accompanied by cold wind, which easily causes heat loss and the deicing rate is slow; in addition, some use mechanical cutters to remove ice Ice deicing device, but its structure is often too complex and the overall device is too heavy, and it also increases the burden on the cable when deicing
