Description

Technical Field

[0001] The present invention belongs to the technical field of cable monitoring equipment, and in particular relates to a cable anti-external damage monitoring device and a monitoring method. Background Art

[0002] With the rapid development of the electric power industry, cables are important carriers of power transmission and distribution, and their safety and reliability are directly related to the stable operation of the entire power system. However, due to various factors such as natural disasters, man-made damage, material aging, and construction quality, cable damage accidents occur from time to time, which not only leads to power outages, but also causes huge economic losses and social impacts. The traditional cable monitoring method mainly adopts the method of manual inspection, which is not only labor-intensive and inefficient, but also has certain safety risks. With the continuous development of the power system and the improvement of the level of intelligence, the requirements for the safety and reliability of cables are also getting higher and higher. The existing technology has developed an intelligent automatic monitoring device that can move along the cable, but when this device is used, it is necessary to manually climb the tower to the cable position and place the device on the outside of the cable before the device can be operated. After use, it is also necessary to manually remove it from the outside of the cable. The whole process is still time-consuming and has safety hazards. Summary of the invention

[0010] A limiting groove is arranged inside the console, and a limiting block is arranged at the lower side of the driving rack.

[0011] A top block is arranged at the end of the driving rack, and a ball is arranged inside the top block.

[0012] A monitoring method for a cable anti-external damage monitoring device comprises the following steps: Step 1: First, make sure that the drone and the main body have been assembled correctly, the hook at the bottom of the drone is firmly connected to the hanging ring above the main body, and can work normally. Start the drone, and the drone will hang the main body on the upper side of the cable under the action of the hook and the hanging ring, so that it hovers at the predetermined position; Step 2: Start the drive motor in the main body through the remote control device, the drive motor drives the movable clamp to move, and clamps the cable through the clamping roller. After the clamping is completed, the drone is separated from the main body, and under the action of the main body's own weight and the counterweight, the main body rotates to the lower side of the cable; Step 3: The clamping roller is driven to rotate by the mobile motor, thereby driving the main body to move along the cable. Under the action of the monitoring probe, the outer surface of the cable can be fully monitored; Step 4: After the cable monitoring is completed, the drone hook is connected to the main body hanging ring again, the driving motor drives the movable splint to open, and the drone drives the main body to separate from the cable, organize and store the device, and recover the tools and equipment.
