A robot-based deicing method for overhead transmission lines

Abstract

The invention discloses a robot based deicing method of an overhead transmission line. The method comprises the following steps that two semicircular deicing plates sleeve the outer wall of a cable, non-hinged ends of the two deicing plates are in clamp connection, an upper casing is disposed on the cable, U-shaped openings of clamping plates make contact with the cable, an lower casing and the upper casing are folded and fixedly connected, an upper collar and a lower collar form a cylindrical area, a stepping motor and a driving motor are started, a gear cooperates with a toothed belt after penetrating a connecting hole, a deicing head is driven to make circular motion, the deicing head starts rotating rapidly in the cylindrical area, helixes move relative to cones, the upper casing starts moving along the axis of the cable, and the deicing head starts to cut ice on the cable rotationally. According to the invention, mechanical deicing replaces a traditional manual knocking manner, the deicing efficiency of the overhead line is improved, and the safety and reliability of deicing of the overhead line are enhanced greatly.

Description

Technical field [0001] The invention relates to the field of electric power deicing, in particular to a robot-based deicing method for overhead transmission lines. Background technique [0002] The snow disaster caused a direct property loss of 10.5 billion yuan for the State Grid Corporation of China. After the disaster, the restoration and reconstruction of the grid requires a large amount of capital investment. The wire in operation generates heat due to the transmission of electric energy. At the beginning of icing, some of the ice will be melted by the heat of the wire. However, the atmospheric temperature and humidity are very beneficial to the icing, and the adhesion of freezing rain is relatively strong, which makes the freezing speed It quickly exceeds the ice melting speed, so the ice coating on the wire will become thicker and thicker. The continuous increase of ice coating causes the wire tension to continue to increase. When it accumulates to a certain extent, it wil...

Problems solved by technology

In cold weather, high-altitude operations bring great safety hazards and construction difficulties to manual deicing, and mainly rely on manual deicing. Electric workers climb up high-voltage line towers and beat along the line with hammers, pull rods, and bamboo sticks to make the ice fall off. But this method is not only inefficient but also poses a great threat to the life safety of electric workers
