Hand-rotated spiral deicing equipment for power transmission line

Abstract

The invention provides hand-rotated spiral deicing equipment for a power transmission line. The hand-rotated spiral deicing equipment adopts a structure that a casing is of a symmetric structure; one end of the casing is hinged through a rotating shaft; the other end of the casing is connected by a fixing device; a deicing gear is arranged on a guide rail and is of a symmetric structure; gear teeth are arranged outside the deicing gear; a conical cavity is formed inside the deicing gear; the power transmission line is arranged inside the conical cavity; a raised structure is arranged on the inner wall of the deicing gear; a zipper is arranged on the gear teeth; two ends of the zipper penetrate through, are movably connected and are mounted on a pinion; a hexagonal slot opening is formed in the middle of the pinion; a rotating handle is mounted in the slot opening. The hand-rotated spiral deicing equipment provided by the invention is simple in structure, simple and convenient to operate, convenient for carrying, high in generality, good in deicing effect and safe for use; the zipper is pulled more conveniently by using the rotating handle, so the labor force is saved; the hand-rotated spiral deicing equipment provides a convenient tool for finishing the deicing work of power cables by deicing workers on the ground.

Description

technical field [0001] The invention relates to the technical field of power transmission line deicing equipment, in particular to a hand-rotating spiral deicing equipment for transmission lines. 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 st...

AI Technical Summary

Problems solved by technology

At present, most of the deicing work of domestic transmission lines still adopts manual deicing methods, such as manual deicing with sticks or shooting with rifles, etc., which requires more manpower and a large amount of material input and cannot reach the required level. effect, and it is difficult to guarantee the safety of deicing personnel

Or use the high-voltage line to melt the ice, but the high-voltage line melts the ice too much energy

The high-current ice-melting method is more efficient, but it costs a lot of money, the operation is complicated, and it has a great impact on the safety of the system.
