A positioning block 8 is fixed below the fitting pad 6, and a positioning groove 9 corresponding to the positioning block 8 is opened on the upper surface of the sealing connection pad 3. The positioning groove 9 and the positioning block 8 form a concave-convex matching structure.

[0020] During use, the sealing connection pad 3 can be first adhered to the equipment installation surface through the adhesive layer 7, and then the fitting pad 6 is placed on the sealing connection pad 3, so that the positioning block 8 is inserted into the interior of the positioning groove 9. Subsequently, it is fixed by the adsorption force of the adsorption cavity 10. The electric energy collection end is connected to the external circuit system, and data is analyzed through the monitoring module 2 and the analysis module, etc. Abnormal data can trigger the alarm 4 and the signal transmitter 5 to work, facilitating relevant personnel to view in time.
