[0031] It needs to be further explained that:

[0032] The first detection assembly 2 is composed of multiple parts, including a first servo motor 209, an oval block 210, a rotating wheel clamping groove 211, and a series of components. The first servo motor 209 serves as a power source, and its output end is fixedly installed with the oval block 210. During rotation, the oval block 210 is matched with the rotating wheel body 212 through the rotating wheel clamping groove 211, driving the sliding rod 213 to move. The limiting rod 214, the positioning plate 215, and the spring 216 sleeved on the limiting rod 214 inside the sliding rod 213 play the roles of limiting and buffering, ensuring the stability of the entire movement process. At the same time, the positioning blocks 217 at the top and bottom of the sliding rod 213 and the sliding grooves 218 further ensure the accuracy of the movement of the sliding rod 213.

[0033] The first detection assembly 2 is equipped with multiple sensors. The sensor unit 203 on one side of the detector cover 201 can detect various parameters of the power cable 1 in real time, such as current and voltage, and timely discover potential hidden troubles. The data acquisition and communication unit 204 is responsible for collecting and processing the data detected by the sensors, and wirelessly transmitting the data to the terminal control machine group through the signal receiving and transmitting module, realizing remote monitoring and fault early warning. In addition, the solar panel 202 at the top of the detector cover 201 provides sustainable energy supply for the entire assembly, improving the environmental protection and economy of the device.

[0034] The first detection assembly 2 also has corresponding design. The second servo motor 220 on the motor mounting plate 219 drives the driving roller 221 to rotate. The driving roller 221 is movably connected at the bottom of the power cable 1, thereby driving the entire assembly to move along the power cable 1. The first roller 207 and the second roller 208 at the bottom of the detector cover 201 assist the assembly to move stably, so that the assembly can comprehensively detect the power cable 1, improving the monitoring range and efficiency.

[0035] The working principle of the above embodiment is as follows:

[0036] Firstly, the first servo motor 209, as the power source of the entire assembly, starts to operate. The oval block 210 fixedly installed at the output end of the first servo motor 209 rotates. The rotating wheel clamping groove 211 on the left and right sides of the oval block 210 is matched with the rotating wheel body 212, driving the rotating wheel body 212 to move. The rotating wheel body 212 is movably installed on one side of the sliding rod 213, thereby making the sliding rod 213 also start to act. The limiting rod 214 fixedly installed in the slot inside the sliding rod 213 plays a limiting role in the movement of the sliding rod 213, ensuring the accuracy of the movement direction. At the same time, the spring 216 sleeved on the limiting rod 214 plays the roles of buffering and resetting during the movement of the sliding rod 213. When the sliding rod 213 moves, the spring 216 is compressed. After the external force disappears, the elastic force of the spring 216 will make the sliding rod 213 return to the initial position. The positioning blocks 217 at the top and bottom of the sliding rod 213 and the sliding grooves 218 further ensure the stability and accuracy of the movement of the sliding rod 213.

[0037] Secondly, the solar panel 202 fixedly installed on the top of the detector upper cover 201 receives sunlight and converts it into electric energy, which is stored in the power module in the groove opened at the position of the sensor unit 203 and the data acquisition and communication unit 204 of the detector upper cover 201, providing continuous and stable power support for each component of the entire first detection assembly 2, ensuring that the equipment can operate normally.

[0038] Then, the sensor unit 203 starts to work, which is internally provided with various sensors that can detect various parameters of the power transmission cable 1 in real time, detect the current and voltage size in the power transmission cable 1, the temperature and humidity of the cable, and whether there is abnormal electromagnetic interference, etc. Through the monitoring of these parameters, the possible hidden dangers of the power transmission cable 1 can be found in time.

[0039] Next, the data acquisition and communication unit 204 collects and preliminarily processes the data detected by the sensor unit 203, and then transmits the processed data to the terminal control machine group in a wireless communication mode through the signal receiving and transmitting module provided in the assembly. The terminal control machine group can further analyze and process these data, realizing remote monitoring and fault warning of the running state of the power transmission cable 1.

[0040] Finally, the second servo motor 220 fixedly installed on the motor mounting plate 219 is started, and the output end of the driving roller 221 fixedly installed on the output end of the second servo motor 220 is rotated. The driving roller 221 is movably connected to the bottom of the power transmission cable 1, and drives the entire first detection assembly 2 to move along the power transmission cable 1 through friction. At the same time, the first roller 207 and the second roller 208 movably installed in the groove at the bottom of the detector upper cover 201 assist the assembly to move stably, so that the assembly can comprehensively detect different positions of the power transmission cable 1, and improve the monitoring range and efficiency.

[0041] The above are the preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
