[0051] Before preparing the far-infrared heating layer 4, it is necessary to prepare the far-infrared heating layer 4, which specifically includes:

[0052] Prepare a carbon nanotube whisker far-infrared heating film 7 and two copper mesh electrodes 8;

[0054] Before preparing the suspension bracket 2, it is necessary to first manufacture the suspension bracket 2, which specifically includes:

[0055] Prepare the horizontal connecting rod 201, the first vertical connecting rod 202, the second vertical connecting rod 203, the first connecting ring 204 and the second connecting ring 205;

[0061] The far-infrared heating device includes a first far-infrared heating device and a second far-infrared heating device; the first far-infrared heating device is fixed to the bottom surface of the first connecting ring 204 by glue or tape, and the second far-infrared heating device is fixed to the bottom surface of the second connecting ring 205.

[0063] Figure 3 This is a schematic diagram of the use process of the high-voltage cable far-infrared heating deicing device provided by the present invention. Figure 3 As shown, the method of using the high-voltage cable far-infrared heating deicing device of the present invention is as follows:

[0064] The thickness of the ice covering the high-voltage cable 6, as measured by the ice thickness sensor, and the distance between the ice layer and the drone 1, as measured by the distance sensor, are collected. The ice thickness and distance information are transmitted to a control device. The control device adjusts the flight altitude of the drone 1 and the heating power of the far-infrared heating device based on the ice thickness and the distance information.

[0065] Specifically, when working, the far-infrared heating layer 4 is energized, and the heat radiated by the far-infrared heating layer 4 heats and melts the ice layer by conduction or convection. When the ice layer is thick, first, the control device lowers the flight altitude of the UAV so that the distance between the far-infrared heating layer 4 and the ice surface is reduced or close to the ice layer to quickly remove ice. Second, the control device increases the heating power of the far-infrared heating layer 4 and increases the heating temperature to quickly remove ice. When the ice layer is thin, the distance between the far-infrared heating layer 4 and the ice surface can be increased or the heating power can be reduced. The power supply of the far-infrared heating layer 4 can be a UAV power supply, an external power supply or the electric energy of the high-voltage cable itself.

[0066] The far-infrared heating layer 4 used in the high-voltage cable far-infrared heating and deicing device of the present invention has an electrothermal conversion efficiency of up to 99%, an extremely fast heating speed, a heating rate of up to 200-500°C / second, an operating temperature of up to 300-500°C, high deicing efficiency and low energy consumption.

The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
