Abstract

The invention relates to a knocking type ice removal for a transmission cable, which mainly consists of a main board, a transverse plate, a battery case, a battery jar, a direct current motor, a belt pulley, a probe reversing bar, a reversing touch disc, road wheels, a knocking arm, a knocking hammer, a belt, magnets, a sensor, a remote control transmitter, a remote control receiver, a fire balloon and a lead wire, and adopts 24V direct current power supply and a 150W direct current motor, wherein, in each road wheel, each magnet is attached on the transmission cable to prevent beating; the direct current motor drives a left road wheel and a right road wheel to walk left and right; the knocking hammer alternately and circularly knocks ice slush on the transmission cable with the frequency of 3 times / s; the sensor receives ice removing information; the remote control transmitter dictates to complete knocking action; the ice removal adopts a wired controllable fire balloon to be hung and dropped straightly. The device has the advantages of reasonable design, compact structure, safety, stability, reliability, energy conservation, good ice removal effect and high efficiency. By knocking to-and-fro, the ice removing ratio of the ice removal can reach 98 percent, the work efficiency is improved by 2 to 3 times than ice removing by milling, and energy can be saved by 500 times compared with ice removing by transforming voltage heat.

Description

Technical field

[0001] The invention relates to a knock-type deicer for power transmission cables, belonging to the technical field of high-altitude and high-voltage power transmission line maintenance equipment. Background technique

[0002] With the development of power industry, high-altitude high-voltage transmission lines have become indispensable equipment. The height of high-voltage transmission lines is mostly 15-20 meters, and the voltage of transmission lines is mostly 110KV, 220KV, 330KV, 500KV. my country has built 300KV. , 500KV transmission lines more than 50,000 kilometers.

[0003] High-altitude high-voltage transmission lines can operate normally at 5-50℃. In case of special climatic conditions, sudden snowstorms or rain and snow, the temperature fluctuates from 0 to -40℃, and there is often ice formation on transmission cables. It will accumulate more and more, greatly endangering the operational safety of high-voltage lines. The diameter of high-voltage cables ...
