[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] Example 1: As Figures 1 to 4 As shown, a cable insulation monitoring device includes a lower arc plate 11 and an upper arc plate 12. The lower arc plate 11 and the upper arc plate 12 cooperate to form a cylinder 1 that is sleeved on a power cable 4. A drive motor 2 and a traveling wheel 3 are provided on the upper arc plate 12. The lower part of the traveling wheel 3 extends into the cylinder 1 and abuts against the power cable 4. The drive motor 2 is used to drive the traveling wheel 3 to rotate. A monitoring component 5 for monitoring insulation defects and a painting component 6 for marking on the power cable 4 are provided on the lower arc plate 11. The monitoring component 5 and the painting component 6 are distributed on both sides of the traveling wheel 3.

[0027] The monitoring component 5 and the painting component 6 are both mounted on the lower arc plate 11, making the counterweight on the lower arc plate 11 greater than the counterweight on the upper arc plate 12. This helps to prevent the cylinder 1 from overturning and ensures that the traveling wheel 3 can maintain stable and continuous contact with the power cable 4.

[0028] This cable insulation monitoring device can move autonomously and mark defect locations. It not only has high marking accuracy, but also eliminates the need for maintenance personnel to observe the device's location in real time, reducing manual intervention and helping to reduce the workload of maintenance personnel. At the same time, it can complete the defect detection and marking of the entire power cable 4 in a short time, improving work efficiency.

[0029] Example 2: Figures 2 to 5As shown, the rest is the same as example one, the difference is that the inner concave arc surface of the lower arc plate 11 is downwardly recessed to form a mounting groove 111, the monitoring assembly 5 includes a controller 51, a Hall sensor 52, a power supply 53 and a carbon brush 54, the controller 51, the Hall sensor 52 and the power supply 53 are arranged in the mounting groove 111, and the carbon brush 54 is arranged at one end of the inner side of the barrel 1, specifically, the end in the running direction, and the Hall sensor 52, the power supply 53 and the carbon brush 54 are electrically connected with the controller 51 respectively.

[0030] In this embodiment, the paint spraying assembly 6 includes a mounting seat 61, which is fixedly connected with the outer convex arc surface of the lower arc plate 11, and the mounting seat 61 is provided with a paint spraying tank 62, a clamp 63, an air cylinder 64 and a pressing plate 65. The clamp 63 and the air cylinder 64 are fixedly connected with the mounting seat 61 respectively.

[0031] When the surface of the power cable 4 has an insulation defect, the current can be monitored by the Hall sensor 52 through the carbon brush 54, and fed back to the controller 51. The controller 51 controls the air cylinder 64 to start, so that the pressing plate 65 presses the nozzle 621 of the paint spraying tank 62 to make a paint mark on the power cable 4. After the marking is completed, the pressing plate 65 is separated from the nozzle 621 of the paint spraying tank 62.

[0032] Example three: as shown in Figure 4 and Figure 5 The rest is the same as example two, the difference is that the nozzle 621 is connected with an extension pipe 622, and the extension pipe 622 faces the power cable 4. The setting of the extension pipe 622 helps to improve the accuracy of paint spraying and reduce the deviation of paint marks caused by the environment (such as strong wind).

[0033] Further, in order to improve the stability of the extension pipe 622 and accurately align the power cable 4, a positioning rod 112 is fixedly arranged at the end of the lower arc plate 11, and a positioning hole 1121 is arranged on the positioning rod 112. The extension pipe 622 is arranged through the positioning hole 1121 to increase the positioning point of the extension pipe 622.

[0034] In this embodiment, a counter 7 is arranged on the mounting seat 61, and the counter 7 is electrically connected with the controller 51. The counter 7 is arranged to count the number of insulation defects monitored by the monitoring assembly 5, so as to avoid missing detection in the later maintenance process of the whole power cable 4 by the maintenance personnel.

The drive shaft of the drive motor 2 passes through the connecting hole 122 and connects to the center of the traveling wheel 3. The lower part of the traveling wheel 3 extends out of the receiving groove 121 and abuts against the power cable 4. This design is compact and easy for maintenance personnel to carry.

[0036] In this embodiment, one side of the lower arc plate 11 is axially connected to one side of the upper arc plate 12, and the other side of the lower arc plate 11 is locked to the other side of the upper arc plate 12 by the locking component 8.

[0037] Example 5: Figure 2 and Figure 3 As shown, the rest of the components are the same as in Embodiment 4, except that the locking assembly 8 includes a fixing plate 81, a connecting plate 82, and a bolt 83. The fixing plate 81 is fixedly connected to the other side of the lower arc plate 11, and a screw hole 811 is provided on the fixing plate 81. The connecting plate 82 is fixedly connected to the other side of the upper arc plate 12, and a through hole 821 communicating with the screw hole 811 is provided on the connecting plate 82.
