De-icing mechanism for high-voltage wire de-icing device

Abstract

The invention discloses a deicing mechanism for high-voltage line deicing devices. The deicing mechanism is provided with a deicing frame which can be driven to rotate by virtue of a power mechanism, the periphery of the deicing frame is provided with deicing rubber bars which can knock high-voltage lines in the rotating process of the deicing frame, and the deicing rubber bars are arranged between upper and lower high-voltage lines through a rack so as to simultaneously knock the upper and lower high-voltage lines in the rotating process; two deicing mechanisms are arranged, the two deicing mechanisms are opposite in rotating direction, and the two deicing mechanisms are respectively arranged on both sides of the rack so as to knock the high-voltage lines which are divided into left and right groups and parallelly arranged; the deicing frame is cross-shaped, the four end parts of the cross-shaped deicing frame are respectively provided with one deicing rubber bar, and the outer wall of each deicing rubber bar is provided with an axial arc groove. By using the deicing mechanism disclosed by the invention, high-voltage line waving caused by the torque of a deicing motor can be eliminated in the deicing process, and then the occurrence of strand breaking at a high voltage is avoided, thereby greatly improving the operating efficiency of deicing and the deicing effect.

Description

technical field [0001] The invention relates to a high-voltage electric wire deicing device, in particular to a deicing mechanism for a high-voltage electric wire deicing device. technical background [0002] With the rapid development of my country's economy, more and more ultra-high-voltage large-capacity transmission lines have been built. Long-distance power transmission usually uses 220KV high-voltage lines for transmission, and the 220KV high-voltage lines have four sub-conductors fixed on spacers. However, the high-voltage line deicing devices currently researched in China usually deicing a sub-conductor, and the commonly used methods are impact deicing and percussion vibration deicing. [0003] Impact deicing uses the friction between the traveling mechanism and the electric wire to remove the icing on the high-voltage line, but this deicing method is greatly affected by the environment, and the existence of obstacles will hinder the operation of the entire device. ...
