A de-icing device for high-altitude cable eddy current using UAV in winter

Abstract

A high-altitude cable eddy current deicing device for UAVs in winter, including two symmetrical splints, the two splints are hinged through a hinge column, and a tension spring is elastically connected between the two splints. The left end of the splint is fixed with an ice-breaking frame, and the inner side of the ice-breaking frame is fixed with a fixed shell. The inside of the fixed shell is fixed with a uniform electric field. The inner wall of the fixed shell is slidably installed with a telescopic rod. The two ends of the upper surface of the metal block are elastically connected to the lower end of the fixed shell through a telescopic spring, and a fixed ball is fixedly installed on the left end of the inner wall of the ice-breaking frame. Through the combined use of fixed balls, contact blocks and breaking balls, when the ice-breaking frame pinches the high-voltage line body, the pinching force released by the ice-breaking frame can be used to conveniently and effectively crush the ice on the high-voltage line body, double deicing , to avoid all-round deicing that cannot be achieved only by metal blocks.

Description

technical field [0001] The invention relates to the field of cable safety technology, in particular to a deicing device for a high-altitude cable eddy current using an unmanned aerial vehicle in winter. Background technique [0002] The high-voltage lines for power transmission are interspersed between various cities and rural areas. At the same time, in winter, ice and snow cover the circuits, which is one of the biggest natural disasters in the power grid system. When the air temperature is below zero, some light raindrops fall on the wires , because the wires are made of metal, the specific heat capacity is small, so most of the metal wires are also below zero, so that the rain is easy to form rime on the wires, and if most of the wires are wrapped in ice, it will form ice coating on the wires , due to the heavy weight of the ice, the weight of the wire itself is increased, the line may be interrupted, or the load of two adjacent wire supports is increased, causing the su...

[0002] The high-voltage lines for power transmission are interspersed between various cities and rural areas. At the same time, in winter, ice and snow cover the circuits, which is one of the biggest natural disasters in the power grid system. When the air temperature is below zero, some light raindrops fall on the wires , because the wires are made of metal, the specific heat capacity is small, so most of the metal wires are also below zero, so that the rain is easy to form rime on the wires, and if most of the wires are wrapped in ice, it will form ice coating on the wires , due to the heavy weight of the ice, which increases the weight of the wire itself, the line may be interrupted, or the load of two adjacent wire supports will be increased, causing the support to collapse and eventually destroy part of the circuit, and people cannot live normally.
