Description

Technical Field

[0001] The present invention belongs to the technical field of power line maintenance, and more specifically, relates to an ice removal device for transmission lines. Background Art

[0002] Under extreme weather conditions such as ice and sleet, freezing rain, etc., icing of transmission lines becomes an inevitable problem. For transmission lines with relatively severe icing, the most effective method of manual ice removal on the line is usually adopted, but this method is highly dangerous and the ice removal speed is very slow. With the development of technology, currently, in addition to manual labor, two main methods are used for ice removal: the thermal ice melting technology that increases the current of the transmission line to heat up the transmission line and melt the ice; the mechanical ice removal technology that relies on mechanical external force. Among them, the ground wire of the transmission line lacks the conditions for thermal ice melting because current cannot be input. Therefore, from the perspective of wider applicability, many scholars have started to study ice removal robots for transmission line ground wires. Different ice removal robots adopt different ice removal mechanisms to remove the ice on the transmission line ground wire by applying mechanical force.

[0003] In the prior art, during the operation of ice and snow removal equipment, only knocking on the ice can be implemented. However, when the ice is damaged by knocking, a part of the ice still remains on the transmission line, resulting in poor ice removal effect, and manual operation of the equipment for ice removal is required, leading to low ice removal efficiency.
