Description

Technical Field

[0002] A high-altitude cable deicer is a device used to remove ice on the surface of power transmission lines or cables. It is usually used for the maintenance of power transmission lines in cold climates. A high-altitude cable deicer usually removes ice and snow on the surface of the cable by heating or vibration. A heating deicer transfers heat to the cable surface through a heating element (such as a resistance wire or a heating plate) to melt the ice and snow. A vibrating deicer vibrates the cable surface through a vibration device to shake off the attached ice and snow. Existing high-altitude cable deicers are mainly fixed on the cable rack or the cable surface, and have a limited coverage range. They cannot completely cover the entire length of the cable, resulting in the failure of effective melting of the ice layer in some areas. There are problems such as inconvenient operation and more manual intervention, lack of automatic operation functions, and reduced work efficiency; in addition, the existing deicer may only have a deicing function, lack of other functional modules, such as monitoring sensors, etc., and cannot achieve comprehensive monitoring and inspection of the cable status. . In view of this, the existing problems are studied and improved, and a high-altitude cable operation and maintenance deicer is provided to solve the current problems, aiming to achieve the purpose of solving problems and improving practical value through this technology.

[0027] Specifically, the mobile drive assembly 200 is fixed to the cable surface by locking the upper sleeve 110 and the hanger 120, and various control devices are mounted on the bottom of the hanger 120 to increase the relative weight of the hanger 120, thereby maintaining the vertical state of the mobile frame 100 on the cable surface by gravity.

[0028] In this embodiment, the surfaces of the upper sleeve frame 110 and the hanger 120 are provided with bushings 130 symmetrically arranged at both ends of the pulley row 240. The bushings 130 are semicircular arc structures and are made of polytetrachloroethylene.

[0029] Specifically, two bushings 130 on the surface of the upper sleeve 110 and the hanger 120 are combined to form an annular sleeve connected to the surface of the cable, so as to achieve the guiding movement of the upper sleeve 110 and the hanger 120 on the surface of the cable.

[0030] In this embodiment, the pulley row 240 is a strip-shaped structure, and a plurality of pulleys inside the pulley row 240 are arranged in a straight line and parallel to the surface of the fixing base 210 .

[0037] The working principle and use process of this utility model:

[0038] During the deicing operation of the high-altitude cable maintenance, the deicer is sleeved on one end of the cable, and the upper sleeve 110 and the hanger 120 are locked together to form an integral structure that embraces the surface of the cable, so that the pulley rows 240 on the surface of the two mobile drive components 200 are elastically pressed against the cable surface under the support of the dynamic support rod 211 and the shock-absorbing support rod 222. The inner pulley of the pulley row 240 slides along the cable surface under the drive of the drive motor 230. The cable is located between the upper sleeve 310 and the lower sleeve 320, connecting the mobile drive component 200. 00 and the circuit of the heating tube group 300 perform contactless radiation heating on the cable surface through the radiation heating of the mercury lamp rod 330. Due to the transparent nature of the ice layer, the infrared light heats it less but has a good penetration effect. The black insulating layer on the cable surface absorbs a lot of heat and can heat up quickly, melting from the inside out, avoiding the problem of ice layer sticking to the cable surface and being unable to fall off. Moreover, the upper sleeve 310 and the lower sleeve 320 are heated by the mercury lamp rod 330 to form a relatively concentrated hot zone, which has a certain melting effect on the ice layer on the cable surface.
