[0106] Example 9
[0107] Based on Example 8 above, after the transmission line is sprayed, the coating layer is dried in an environment with a humidity of 50-60% to obtain the fourth coating layer.
[0108] After testing, the fourth coating obtained in this way has the advantages of making the connection of the power transmission line more secure and having a better anti-icing effect.
[0109] like Figure 1 As shown, the present invention also provides a device for coating anti-icing paint on power transmission lines, characterized in that: it includes a frame 1, on which are mounted a raw material roller 11 and a product roller 12 for power transmission lines. The raw material roller is a roller wound with uncoated power transmission lines, and the product roller is a roller wound with coated power transmission lines. The power transmission lines form a coating path 13 from the raw material roller to the product roller, and the coating path from the raw material roller to the product roller is from back to front. A low-temperature chamber 2 at the rear and a spraying chamber 3 at the front are mounted on the frame. The low-temperature chamber has a low-temperature chamber inlet and a low-temperature chamber outlet, and the spraying chamber has a spraying chamber inlet and a spraying chamber outlet. The coating chamber outlet has a coating route that passes through a low-temperature chamber and a spraying chamber. The low-temperature chamber has a temperature regulating component, specifically a first temperature regulating component 23, which can maintain the temperature of the transmission line at 10-15°C.

[0111] To elaborate further, the temperature regulating component is a heating element or a cooling element of an air conditioner.
[0112] In short, as long as the temperature of the low-temperature room and the spray booth can be adjusted to reach the required temperature, it will be fine.
[0113] Furthermore, a drying chamber 4 is installed in front of the spraying chamber. The drying chamber has a drying chamber inlet and a drying chamber outlet. Inside the drying chamber, there is a humidity monitor 43 and a humidity regulator 44. The humidity regulator has a humidity regulating outlet that leads to the drying chamber. The humidity monitor and the humidity regulator are connected to a control device. The control device adjusts the humidity inside the drying chamber to 50-60% based on the data transmitted from the humidity monitor.
[0114] In this way, the coating of the transmission lines produced by this device is more in line with the coating production process, and the connection between the coating and the transmission lines is stronger.
[0115] In one embodiment, the control device is a programmable controller or a PLC, etc.
[0116] Furthermore, the humidity regulator includes a dryer and a humidifier.
