AI Technical Summary

Technical Problem

Existing de-icing technology for transmission lines mainly responds passively and lacks active defense. It is also prone to cause line damage and electrical failures in severe weather, posing a serious threat to line safety.

Method used

A mechanical autonomous de-icing device is used, including a protective cover, a piezoelectric sensing device and a mechanical de-icing escapement. The piezoelectric device is used to generate electricity and drive the mechanical de-icing escapement. The ice is removed through the escapement wheel and sawtooth structure, and automatic de-icing is achieved by combining the gravity lever and the lever structure.

Benefits of technology

It achieves timely mechanical autonomous de-icing, reduces dependence on operation and maintenance personnel, ensures line safety, and has a simple device structure and light weight, which does not affect line operation.

Abstract

The invention provides a power transmission line mechanical autonomous deicing device which is provided with a protective cover, a piezoelectric induction device, a mechanical deicing escapement device and a stop lever structure, the mechanical deicing escapement device comprises an escape wheel, a fixing rod and an escapement fork part, the escape wheel is a circular ring, the inner circle edges of the circular rings on the two sides protrude out of the circular ring by a part to form protruding sections, and the fixing rod and the escapement fork part are arranged on the protective cover. The top of the inner circle is an inner ring hinge which can be opened and closed, the top of the outer circle is an outer ring hinge which can be opened and closed, and the inner ring hinge and the outer ring hinge sleeve the wire with the mechanical deicing escapement device; and sharp sawteeth are arranged on the outer circle. When icing reaches a certain thickness, gravity presses a gravity lever to trigger a piezoelectric device, electric energy is released to drive a motor stop lever structure, a mechanical deicing escapement device is released, mechanical active deicing is achieved through rotation of an escapement wheel and cutting of an icing body by sawteeth, and the operation reliability of a power transmission line is guaranteed. And an over-thick ice layer does not appear on the wire without waiting for operation and maintenance repair personnel.
