Abstract

The invention discloses a transmission line ice melting device, belonging to the technical field of transmission line maintenance, which comprises a moving tool car, a supporting mechanism and an icemelting mechanism. The mobile tool vehicle is provided with a centrifugal pump and a liquid storage cylinder storing liquid ice-melting agent, wherein the liquid storage cylinder is connected with theinlet of the centrifugal pump through an inlet pipe, and the outlet of the centrifugal pump is connected with the lower end of the Y-shaped outlet pipe; The support mechanism comprises a base and a support frame arranged on the base; The support frame comprises a first support bar, a second support bar and a Y-shaped fixing groove; The ice melting mechanism comprises a U-shaped first nozzle and an inverted U-shaped second nozzle, wherein a first branch of the outlet pipe is connected with the first nozzle, and a second branch of the outlet pipe is connected with the second nozzle. The invention can completely cover the circuit, thoroughly melt ice, and additionally provides a melting agent suitable for the melting device, which has low freezing point, fast melting rate in a short time, remarkable melting effect, and little harm to carbon steel and plants.

Description

technical field [0001] The invention relates to the technical field of power transmission line maintenance, in particular to a power transmission line melting device. Background technique [0002] After entering winter, rain, snow and freezing weather appear in most parts of my country, and transmission lines often suffer from ice-covered disasters of varying degrees. The icing of transmission 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 transmission lines is a complex 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 home and abroad, but the deicing mechanism can be sum...
