De-icing device for electric wire

The invention provides a wire deicer, which belongs to the field of power auxiliary equipment, and can move on wires automatically to remove ice from wires. The wire deicer comprises a chassis. A wire access channel is arranged on one side of the wallboard of the chassis. A motor (9) outputs power through a driving shaft (10), and drives the actuator of a front wire reel (25) and a rear wire reel(20) to move on a wire (54), which drives an actuating mechanism through a crank shaft No.1 (32) and a crank shaft No.2 (33) on a gear No. 7 (29) and a gear No. 8 (31) engaged with each other. The mechanism comprises an upper shovel holder (39) and a lower shovel holder (40) opened and closed periodically. An assorted upper ice shovel (41) and an assorted lower ice shovel (42) are arranged at thefront ends of the upper shovel holder (39) and the lower shovel holder (40) respectively. The upper ice shovel and the lower ice shovel are opened and closed periodically when moving to cut and crackice. The wire deicer further comprises an automatic control system consisting of a field control part arranged in a wireless mode and a control part on the machine body. The automatic control system can automatically control the operation mode according to the weather conditions of ice and snow, and ensure power transmission lines, pylons and cable trays safe to prevent accidents. The wire deiceris applicable to various wires of different diameters, and has the advantages of is portability and flexibility, convenient use, and stable and reliable running, long service life, convenient maintenance and easy manufacture.
