Description

Technical Field

[0001] The utility model belongs to the technical field of deicing of overhead cables, in particular to a deicing mechanism for overhead cables. Background Art

[0002] Due to the complex areas that power transmission cables pass through, coupled with the influence of climate and other factors, water droplets will adhere to the surface of the cable. When these water droplets encounter low temperatures or cold waves, they will form ice on the surface of the cable. A thinner ice layer has less impact on the cable, but a thicker ice layer will have a more serious impact on the cable.

[0003] After searching, the Chinese utility model patent with announcement number: CN209119773U discloses a walking mechanism in a cable deicing device. Although the above mechanism improves the stability of the movement of the mechanism through two driving wheels and a first side wheel and a second side wheel, deicing is achieved by rolling the surface of the cable through two sets of upper and lower driving wheels and a pressure wheel. During rolling deicing, since the two sides of the cable are not in direct contact with the pressure, residual ice debris may still be attached to the cable, resulting in poor cleaning effect on the cable.

[0004] Therefore, we propose an overhead cable deicing mechanism to solve the above problems. Utility Model Content
