AI Technical Summary

Technical Problem

Existing de-icing technologies cannot simultaneously meet the demands for high operational efficiency, high safety, and low cost. In particular, for types of frost that are loosely structured and easily detached, existing technologies suffer from high labor intensity and difficult equipment operation.

Method used

A gas de-icing device was designed, including a hanger, a left hanger, a right hanger, a cylinder, a gas storage component, and a control valve. The device is hoisted above the guide wire using a drone. The reciprocating motion of the cylinder piston rod drives the impact head to impact the ice upward, achieving rapid de-icing.

Benefits of technology

It improved the efficiency of wire de-icing operations, reduced operational difficulty, decreased labor intensity, reduced equipment load, and extended the flight time of drones.

Abstract

The invention relates to the technical field of power grid deicing, in particular to a gas deicing device which comprises a hanging frame, a left hanging frame, a right hanging frame, an air cylinder, a gas storage assembly and a control valve. The gas deicing device is reasonable and compact in structure, when the gas deicing device is used, the hanging bracket and the body of the unmanned aerial vehicle are installed together, the gas deicing device is hoisted to the position above a wire to be deiced through the unmanned aerial vehicle, then the height is lowered, the wire moves upwards into the hanging groove relative to the gas deicing device, and then the unmanned aerial vehicle is separated from the hanging bracket; the unmanned aerial vehicle and the hanging bracket are detachably installed together through the prior art, the operation difficulty is low, and then the control valve starts to work, so that the air storage assembly intermittently provides an air source for the air cylinder, the piston rod of the air cylinder continuously reciprocates up and down to drive the impact head to move upwards to impact the lower side of an iced wire, and the wire is protected. The impact of the impact head on the iced wire can realize large-area rapid deicing operation of the line, and the deicing operation efficiency of the wire is improved.
