Special tool for quickly removing ice coatings of power transmission line

Abstract

The invention discloses a special tool for quickly removing ice coatings of a power transmission line. The tool comprises a deicing box, a gap-adjusting mechanism, an ice crushing mechanism and a wiretake-up mechanism; the inner wall of the deicing box is slidably connected with the gap-adjusting mechanism; the top of the gap-adjusting mechanism is fixedly connected with the ice crushing mechanism; and one end of the outer side of the deicing box is fixedly connected with the wire take-up mechanism. The tool of the invention is compact in structure. Since the gap-adjusting mechanism is adopted, a gap between a first ice crushing gear and a second ice crushing gear can be adjusted according to the diameter of the power transmission line through a gap-adjusting screw rod under the action ofa left-hand thread and a right-hand thread, so that the tool can be used for power transmission lines of different diameters, and therefore, the application range of the ice crushing tool is expanded; a wire take-up box is adopted, the length of a drawstring can be adjusted flexibly according to needs, and therefore, the structure of the ice crushing tool is flexible and adjustable, the practicability of the ice crushing tool is greatly improved, the ice coatings of wires inside a span can be quickly treated, and the ice coatings can be prevented from affecting the safe operation of the transmission line.

Description

technical field [0001] The invention relates to the technical field of transmission lines in electric power systems, in particular to a special tool for quickly removing icing on transmission lines. Background technique [0002] At present, icing on transmission line conductors is a common phenomenon, and the faults caused by icing on transmission lines seriously affect the normal operation of the power system. Icing mainly causes faults such as galloping and breaking of conductors, tilting and collapse of towers, and flashover of insulators, which seriously endanger power transmission. Safe and stable operation of the line. Therefore, once there is an ice-covered wire scene, it needs to be dealt with in time, otherwise it will cause serious consequences. At present, the treatment of icing on wires is mostly to manually climb up the iron tower and beat the wires manually, which can remove the ice on the wires close to the iron tower. The ice on the wires in the stalls canno...

Problems solved by technology

[0002] At present, icing on transmission line conductors is a relatively common phenomenon. The faults caused by icing on transmission lines seriously affect the normal operation of the power system. Icing mainly causes faults such as galloping and breaking of conductors, tilting and collapse of towers, and flashover of insulators, which seriously endanger power transmission. Safe and stable operation of the line

Therefore, once an ice-covered conductor occurs, it needs to be dealt with in time, otherwise it will cause serious consequences

At present, the treatment of icing on wires is mostly to manually climb up the iron tower and beat the wires manually, which can remove the ice on the wires close to the iron tower. The ice on the wires in the stalls cannot be treated, and can only be waited for. It melts by itself, which affects the safety of the transmission line. run
