An overhead electrical line is one of the indispensable fixed components of modern power grids. It is characterized by long transmission distance, high efficiency and easy maintenance, it has been widely used in overhead power transmission line. Especially in winter when the temperature is below 0 degrees, ice deposits often form on the overhead line, the masses of which exceed the net mass of the conductors by tens or even hundreds of times, which causes high mechanical stress on the conductors, insulators and guy poles. Such accumulations of ice lead to damage to lines and to supply interruptions. Therefore, de-icing for overhead line is the most urgent technical problem to be solved, with the main conventional de-icing methods including hand-operated de-icing, mechanical de-icing and self-heating de-icing.

Impact head 100 together with the tertiary drive system 7, which drives the impact head to swing up and down, on the side of the impact chamber there is a camera 8, which is used to take pictures of the line 1 to be de-iced, which is then sent to the control mechanism after the identification service analysis the line is separated from ice, if there is no ice layer, the primary drive system is commanded to go forward, otherwise the tertiary drive system 7 is ready for de-icing.

The impact head 100 includes the impact plate 1001, the upper end of 1001 of which is slightly curved, when it hits the ice layer or the ladder rope, the ice layer and the ladder rope swing up to easily break the ice sheet, and the damage caused by swinging up and down to minimize. When heating the line, it starts to peel off the ice sheet from the line, after the two are separated from each other, the impact head 100 hits the ice sheet to break the ice sheet at that point when the impact head hits the conductor wire, the line swings up and down to break the ice of the other area outside the joint, the more of the open gaps, the better the sphere of action of breaking to other parts of the line outside the joint. This device is able to increase the effective length of the rupture on the line 1, reducing the number of joints while increasing the de-icing efficiency.

Pushing head 100 comprises two push-out plates 1002 mounted on both sides of push-out plate 1001, the distance of which from edges of push-out plates 1002 to push-out plate 1001 gradually decreases. This construction is capable of pushing out the conductor's ice layer from sides by 1002 to increase efficiency. However, the narrowest point between the two push-out plates is larger than the diameter of the conductor to prevent the 1002 wire from being jammed.

The impeller 2 runs to the place to be de-iced, stops, then the tertiary electric motor 71 starts to work, impact head 100 hits the ice layer to make the ice layer break and fall, after the ice layer is removed at this point, the on and ab oscillating shock process continues to cause vibrations of the conductor rope, which also breaks the ice layer outside the joint along the line, after the specified shocks have been completed, impeller 2 continues to move forward, if ice layer gets in the way again while driving, then the impeller stops, keeps hitting the ice layer of the pipe, until the de-icing work is completed on the whole pipe.

During heating by the heating system, a small gap is formed between the pipe and the ice layer, it is no longer imperative to apply too much heat to melt the ice layer, but to let it fall free under the action of gravity by itself, or by external forces Force action to remove the ice layer, or to extend the effective path of breaking on the line by swinging up and down. Methods such as heating and tapping accelerate the de-icing process, shorten the de-icing time, reduce negative influences on the power transmission and save electricity at the same time.
