[0026] By setting up the battery tube 6, the image detector 7 and the anti-fog cover 12, when the inspector detects whether there is thin ice on the outer surface of the transmission line, the power supply of the image detector 7 can be directly turned on to enable it to collect images of the outer surface of the transmission line, and then the image data is transmitted to the ground receiving end through the signal block 14.
