[0014] Example: In a specific implementation process, the device operates as follows.

[0015] The first guide wheel structure (1) has an inclination sensor mounting platform (6) at one end for placing the inclination sensor. The inclination sensor mounting platform has waterproof sealing ring grooves (4) at both ends, and the installation of the waterproof sealing rings can prevent water seepage into the structure. The end connected to the main body of the first guide wheel structure (1) is provided with a thread (7). The inclination sensor mounting platform (6) is placed into the inclinometer rod (2) and fixed by an insert screw to make the structure tightly connected. The inclination sensor mounting platform (6) has a line hole (5) that passes through the main body of the first guide wheel structure (1) on its side wall. The connecting wire of the inclination sensor can pass through the line hole (5) and connect to the connector (9) at the other end of the first guide wheel structure (1) to obtain monitoring data. The other end of the first guide wheel structure (1) is provided with a flight plug connector (10), which has an annular groove (11) inside. The flight plug (9) is inserted into the flight plug connector (10) to the annular groove (11), and then the flight plug connector (10) is connected to the main body of the first guide wheel structure (1) by an insert screw, which facilitates the disassembly and replacement of the flight plug.
