During this period, the infrared thermal imager 11 remains in the non-activated thermal imaging mode, and first detects the appearance of the insulating porcelain sleeve 3. When the insulating porcelain sleeve 3 has obvious cracks, it means that the insulating porcelain sleeve 3 has a safety hazard and needs to be replaced. After the scanning mounting gear ring 86 rotates counterclockwise by 120 degrees, the external remote control can be controlled, and the drive motor 89 runs in the reverse direction, and the scanning mounting gear ring 86 rotates back clockwise. During this period, the infrared thermal imager 11 turns on the thermal imaging mode to detect whether the upper and lower sides of the insulating porcelain sleeve 3 are abnormally heated. In this process,The maximum rotation angle of the scanning and mounting gear ring 86 does not exceed 120 degrees to prevent the first gear 83 from losing the meshing relationship with the scanning and mounting gear ring 86.

Then, each porcelain skirt of the insulating porcelain sleeve 3 can be detected in turn through the above method to complete the insulator safety detection operation.

[0020] The working principle of a power transmission line insulator safety detection device provided by the present invention is as follows: when the safety detection device is needed, the device can be lifted by an external lifting drone and a hook 10, and then the internal and external drones are controlled to move the device to the upper side of the insulating porcelain sleeve 3 of the high-voltage line, and then the two counterweight frames 28 are used as references to place the device on the outer surface of the insulating porcelain sleeve 3. At this time, the outer surfaces of the two rubber walking tracks 25 contact the insulating porcelain sleeve 3. At this time, the external remote control can be adjusted to send out an electrical signal, which is then received by the wireless transceiver 7.

At this time, after moving the equipment to the upper side of the porcelain skirt of the insulating porcelain sleeve 3, the external remote control electric telescopic rod 56 can be adjusted to operate, and the telescopic end of the electric telescopic rod 56 will shrink, thereby driving the contact rod 53 to rotate around the central axis of the measuring and installing rotating rod 51 until the contact rod 53 contacts the two sides of the porcelain skirt. At this time, if there is current on both sides of the porcelain skirt, it will be conducted by the contact rod 53. At this time, the current detector 57 can capture this current information and report the information in real time. At the same time, it indicates that there is a safety hazard in the insulating porcelain sleeve 3. During this period, the external remote control can be adjusted to drive the motor 89 to operate, and the output shaft of the drive motor 89 will rotate clockwise for a specified number of circles, thereby driving the first gear 83 to rotate clockwise through the first mounting rod 82. The needle rotates a specified number of circles, thereby driving the scanning and installing gear ring 86 to rotate counterclockwise by 120 degrees. During this period, the infrared thermal imager 11 remains in the non-activated thermal imaging mode. The appearance of the insulating porcelain sleeve 3 is first detected. When the insulating porcelain sleeve 3 has obvious cracks, it indicates that the insulating porcelain sleeve 3 has a safety hazard and needs to be replaced. After the scanning and installing gear ring 86 rotates counterclockwise by 120 degrees, the external remote control can be adjusted to drive the motor 89 to run in the reverse direction, and the scanning and installing gear ring 86 rotates back clockwise. During this period, the infrared thermal imager 11 turns on the thermal imaging mode to detect whether there is abnormal heating on the upper and lower sides of the insulating porcelain sleeve 3. If so, it indicates that the insulator has a safety hazard and needs to be replaced. Then, each porcelain skirt of the insulating porcelain sleeve 3 can be detected in turn in the above manner.Complete the insulator safety inspection.
