Description

Technical Field

[0002] For high- and low-voltage overhead transmission and distribution lines, regular inspections, fault inspections, and special inspections must be carried out during routine operation and maintenance. Inspections are usually conducted manually or by observing remotely with the aid of binoculars. However, conventional inspection methods have blind spots and cannot provide a comprehensive view of the equipment's normal operation.

[0003] Faults in some blind spots and hidden areas are difficult to detect, and even remote observation with binoculars cannot accurately obtain detailed information about the equipment, such as the overheating of wires, broken strands in the lines, overheating at line connections, and carbonization due to discharge.

[0055] The gyroscope in the inspection device 2 on the bottom is activated, the flip wheel frame 311 opens, and the drone 1 transports the device to the line 7 that needs to be inspected.

[0058] When the first inner plate 406 and the second inner plate 507 rotate, they reciprocate and swing to ensure that the entire circumference of line 7 can be photographed. In some special cases, this inspection device can also be deployed at the faulty part of the line when it is running with a fault to monitor the line problem online in real time.
