Technical Field

[0002] Underground cables are important infrastructure for ensuring urban operation. Compared with overhead cables, they have the advantages of small land occupation, reliable power transmission, and strong anti-interference ability. However, due to their underground location, they are more severely affected by factors such as water accumulation. During laying, pipeline wells need to be equipped at certain intervals for cable connection. Monitoring the working state of the connection points is particularly important, and intelligent monitoring terminals are required to monitor the current, temperature, and attitude of underground cables. Since underground cables are buried deep underground, the monitoring terminals need protection structures to resist extrusion and water seepage.
[0003] At present, the monitoring of cable joints is generally temperature monitoring, powered by batteries, and multiple groups of temperature sensors are led out for mounting and monitoring. This method can effectively monitor the temperature of the outer cable joints, but lacks real-time monitoring of the internal actual temperature and current, and cannot form effective data accumulation and early warning. Moreover, after the underground cables are buried, the bearing protection ability of the cable connection ends is relatively insufficient. Due to reasons such as rain erosion or soil faults, the cables and monitoring equipment may be damaged, and the overall waterproof and compressive protection ability is relatively insufficient, affecting the normal use of the device, and it is not possible to provide good waterproof and compressive protection for multiple cables at a single connection point, and the stability and durability are relatively poor.
