Example 12:
The upper surface of the power transmission line is sprayed with a spraying material for forming a hydrophilic coating, and the spraying material comprises 15% of polycarboxylic acid, 10% of sodium chloride, 2.5% of sodium sulfate, 0.25% of cobalt blue and the balance of water. The lower surface of the transmission line is sprayed with a spraying material forming a hydrophobic coating, which is dimethyl silicone oil containing 0.14 percent of nano ferroferric oxide and 0.20 percent of nano calcium oxide. And the power transmission line is kept stand in the air for three days, so that the carbonization reaction of the nano calcium oxide on the surface is changed into nano calcium carbonate, and the hydrophobic mastoid is optimized.
The wheel with the groove is placed on a power transmission line, the two anti-icing coating spraying devices are combined up and down to form a spherical shell shape, and the wheel is provided with a power device and a power supply, walks on the power transmission line and completes the anti-icing coating spraying.
