Hard spiral deicing device for power transmission line cable

Abstract

A hard spiral deicing device for a power transmission line cable comprises a shell, wherein the inside of the shell is provided with an annular guide rail or a guide groove, the shell comprises two symmetric half bodies, one end of one half body is hinged to one end of the other half body, the other end of one half body is connected with the other end of the other half body through a fixing mechanism, the guide rail or the guide groove is provided with a deicing wheel, the deicing wheel comprises two symmetric half wheel bodies, the outside of the deicing wheel is provided with a wheel tooth, the inside of the deicing wheel is provided with a cone-shaped cavity, the inner wall of the deicing wheel is provided with a convex structure, the wheel tooth is provided with a zipper, the two ends of the zipper penetrate through the shell and are movably connected, and the function of removing ice layers on power transmission lines is effectively achieved. Besides, the deicing wheel is movably connected with the shell through the guide rail or the guide groove and is very convenient to replace, a deicing wheel with a matched through hole can be selected according to cable models, and universality is strong.

Description

technical field [0001] The invention relates to the technical field of deicing devices for power transmission lines, in particular to a hard spiral deicing device for power transmission line cables. Background technique [0002] When the power transmission line encounters rain, snow and freezing weather, the conductor will freeze, and when the ice freezes to a certain thickness, a rod down accident will occur, which will cause great economic losses to the whole society. The most serious icing disasters affected provinces such as Hubei, Sichuan, Guizhou, Guangxi, Anhui, Jiangxi, Hunan, and Zhejiang. The direct economic losses were tens of billions of dollars, and the losses caused by the collapse of the power grid were even more immeasurable. In order to ensure the safe and stable operation of the power grid system, it is necessary to de-ice the ice-covered transmission lines in a timely and safe manner. At present, most of the deicing work of domestic transmission lines sti...

Problems solved by technology

Its disadvantages are that the structure is complex, the drive motor is installed, the cost is high, the equipment is heavy, and the load-bearing capacity of the transmission cable is high. Due to the ice coating has seriously increased the weight of the transmission cable, the overweight equipment has problems in use. great security risk
