[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is mutually exclusive, either alone or selectively, with other embodiments.

[0032] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0033] Example 1, referring to Figures 1-4 The first embodiment of the present invention provides a power cable condition monitoring device, which includes a handheld unit 100, an adjustment unit 200, and a monitoring unit 300.

[0034] The handheld unit 100 includes a handle 101, a control seat 102 mounted on the handle 101, and a connecting seat 103 mounted on the control seat 102. A universal coupling is provided between the control seat 102 and the handle 101. By adjusting the angle between the control seat 102 and the handle 101, the monitoring positions of the control seat 102, the connecting seat 103, and the monitoring unit 300 can be adjusted without adjusting the hand position. The specific working principle is similar to that of existing robotic arm structures. When workers need to perform direct maintenance and monitoring of cables on-site, they only need to hold the handle 101 and connect the adjustment unit 200 and the monitoring unit 300 mounted on the connecting seat 103 to the cable to perform real-time monitoring of the cable's status.

[0035] The adjustment unit 200 includes a frame portion 203 mounted on the connecting seat 103, a female docking portion 201 mounted on the frame portion 203, and a female docking portion 202 mounted on the frame portion 203 and corresponding to the female docking portion 201. The frame portion 203 is equipped with a position adjustment component, which can adjust the positional relationship between the connecting seat 103 and the frame portion 203. This facilitates monitoring of cables in different environments, meeting the monitoring needs of underwater or soil-insulated cables, and allowing for fine-tuning of the position of densely packed cables, preventing data deviation caused by cable accumulation. The female docking portion 202 and the female docking portion 201 facilitate the setting of multiple monitoring points on the cable, and the data transmission between the female docking portion 202 and the female docking portion 201 enables real-time monitoring of the long-distance cable status, improving the accuracy and validity of the data.

[0036] The monitoring unit 300 includes a cable monitoring unit 302 mounted on the frame 203, a connecting part 303 mounted on the cable monitoring unit 302, and a limiting part 301 mounted on the connecting part 303. When workers need to fix the monitoring unit 300 on the cable for long-term real-time dynamic monitoring, they only need to remove the monitoring unit 300 from the frame 203 and fix it on the cable to achieve long-term cable maintenance. The cable monitoring unit 302 is equipped with a remote data transmission module, which can transmit the cable status data back to the central server.

[0037] During use, when staff need to directly maintain and monitor the cable on-site, they only need to hold the handle 101 and connect the adjustment unit 200 and monitoring unit 300 on the connector 103 to the cable to perform real-time cable status monitoring. The frame 203 is equipped with a position adjustment component, which can adjust the positional relationship between the connector 103 and the frame 203, facilitating monitoring of cables in different environments. This meets the monitoring needs of underwater or soil-insulated cables, and allows for fine-tuning of the position of densely packed cables, preventing data deviation caused by cable accumulation. The sub-connection section 202 and the female connection section 201 facilitate the setting of multiple monitoring points on the cable. Data transmission between the sub-connection section 202 and the female connection section 201 enables real-time monitoring of the long-distance cable status, improving the accuracy and validity of the data. When staff need to fix the monitoring unit 300 to the cable for long-term real-time dynamic monitoring, they only need to remove the monitoring unit 300 from the frame 203 and fix it to the cable for long-term cable maintenance. The cable monitoring unit 302 is equipped with a remote data transmission module, which can transmit the cable status data back to the central server.

[0045] During use, when staff need to directly maintain and monitor the cable on-site, they only need to hold the handle 101 and connect the adjustment unit 200 and monitoring unit 300 on the connector 103 to the cable to perform real-time cable status monitoring. The frame 203 is equipped with a position adjustment component, which can adjust the positional relationship between the connector 103 and the frame 203, facilitating monitoring of cables in different environments. This meets the monitoring needs of underwater or soil-insulated cables, and allows for fine-tuning of the position of densely packed cables, preventing data deviation caused by cable accumulation. The sub-connection section 202 and the female connection section 201 facilitate the setting of multiple monitoring points on the cable. Data transmission between the sub-connection section 202 and the female connection section 201 enables real-time monitoring of the long-distance cable status, improving the accuracy and validity of the data.
