Abstract

A line de-icing device for distribution network Include material trolley, a liquid pump and a control switch for controlling the opening and closing of the liquid pump, A liquid storage tank and a liquid pump are arrange on that material trolley, a liquid deicer is store in the liquid storage tank, a pumping port of the liquid pump is communicated with the liquid deicer in the liquid storage tankthrough a water inlet pipe, a deicer mechanism is arrange at the upper end of an insulating operation rod, and a water outlet of the liquid pump is connected with the deicer mechanism through a wateroutlet pipe; The deicing mechanism comprises an L-shaped bracket arranged on the upper side of the insulated operating lever, a fixed shaft horizontally arranged on the outside of the L-shaped bracket, a cylinder rotatably arranged on the fixed shaft through bearings, a sponge cylinder wrapped on the outer surface of the cylinder, and a spraying module arranged on the outside of the L-shaped bracket and positioned directly above the sponge cylinder for spraying liquid deicer downward; The invention can uniformly apply the deicer on the ice covering of the distribution network line, the deicereffect is better, in addition, the deicer suitable for the deicer is provided, the freezing point is low, and the ice is melted in a short time.

Description

technical field [0001] The invention relates to the technical field of operation and maintenance of distribution network lines, in particular to a deicing device for distribution network lines. Background technique [0002] After entering winter, rain, snow and freezing weather occur in most parts of my country, and distribution network lines often suffer from ice-covered disasters of varying degrees. The icing of distribution network lines will lead to accidents such as wire galloping, disconnection, tower collapse, insulator flashover, etc., which will bring great inconvenience to the normal operation of the power grid and people's lives. The icing of distribution network lines is a complicated process, and the amount of icing is related to many factors such as the radius of the wire, the diameter of the supercooled water droplet, the air content, and the temperature. In order to reduce the occurrence of various accidents caused by icing, there are many deicing methods at...
