Deicing device of high-voltage power transmission line

Abstract

The invention relates to a deicing device of a high-voltage power transmission line. The deicing device comprises a support, wherein a limiting guide wheel is arranged in the support, and one side of the limiting guide wheel is provided with a first deicing rod, a second deicing rod and a third deicing rod, all of which are driven by a motor to carry out reciprocating movement; and the lower ends of the first deicing rod, the second deicing rod and the third deicing rod are arranged above the high-voltage power transmission line. The deicing device of the high-voltage power transmission line, disclosed by the invention, alternatively knocks the high-voltage power transmission line from above by utilizing a plurality of deicing rods so as to realize a deicing effect at lower energy. The limiting guide wheel can be used for preventing the deicing rods from breaking the high-voltage power transmission line. Due to the matching of a vibration-absorption spring and a sliding block, the limiting guide wheel can be always tightly pressed on the high-voltage power transmission line, the vibration generated by the deicing rods in a deicing process can be adsorbed, the influence of vibration on other supporting devices is reduced, and the height of the deicing device can be regulated in real time when the high-voltage power transmission line is of gradient so that the deicing effect is ensured.

Description

technical field [0001] The invention relates to the field of maintenance equipment for high-voltage transmission lines, in particular to a high-voltage transmission line deicing device for removing ice from high-voltage transmission lines. Background technique [0002] The icing that occurred from 2003 to 2005 has threatened the stable operation and reliable power supply of the power grid. In 2008, it suffered the most serious icing disaster in the past 50 years. The affected areas include Hubei, Sichuan, Guizhou, Guangxi, Anhui, and Jiangxi. In provinces such as China, Hunan, and Zhejiang, the direct economic loss is tens of billions of yuan, and the loss caused by the collapse of the power grid is 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. [0003] At present, domestic deicing methods mainly include manual deicing, direct curren...
