A deicing robot for overhead transmission lines

Abstract

The invention discloses a deicing robot for an overhead power transmission line. The deicing robot comprises an upper shell and a lower shell. On the same side, sidewalls of the upper shell and the lower shell are respectively provided with a lug plate and two plug plates are connected through bolts. A supporting plate is arranged inside the upper shell. The bottom of the supporting plate is provided with a plurality of clamping plates. Each clamping plate is provided with a U-shaped opening. The bottom of the U-shaped opening is provided with two cones. Two stepping motors are arranged inside the lower shell. The output end of each stepping motor is provided with a connecting rod. The outer wall of each connecting rod is provided with a spiral, and two spirals are respectively matched with the two cones. The bottom of the supporting plate is provided with a connecting plate. An upper lantern ring is used for fixing the lower end of the connecting plate. Along the circumferential direction of a deicing head, the outer wall of the deicing head is provided with a toothed belt. The output end of a driving motor is provided with a gear matched with the toothed belt. According to the technical scheme of the invention, the mechanical deicing manner is adopted instead of the traditional manual beating manner. Therefore, the deicing efficiency of the overhead line is improved, while the deicing safety and the deicing reliability of the overhead line are greatly increased at the same time.

Description

technical field [0001] The invention relates to the field of electric power, in particular to a deicing robot for overhead transmission lines. Background technique [0002] Overhead lines are widely used. Overhead lines have the advantages of economical erection, high load capacity, and convenient maintenance. However, in winter, when the conductor is cooled at 0°C or below, the water droplets in the cloud or fog will collide with the surface of the transmission line conductor and cause damage. When freezing, the wire is covered with ice. This is because the transmission line conductor surrounded by water droplets collides with the supercooled water droplets in the airflow, and freezes on the surface of the conductor to form icing. The icing on the wire first grows on the windward side, and if the wind direction does not change sharply, the thickness of the ice on the windward side will continue to increase. When the ice on the windward side reaches a certain thickness and...

Problems solved by technology

In cold weather, working at heights brings great safety hazards and construction difficulties to manual deicing. Although some robots have been developed to deicing high-voltage lines, most of them have too low power and short battery life, so now they mainly rely on manpower. For deicing, electric workers climb up the high-voltage line towers and beat along the line with hammers, pull rods, and bamboo sticks to make the ice fall off. However, this method is not only inefficient but also poses a great threat to the life safety of electric workers.
