[0019] Working principle: The device has multiple working states. Different tools are selected according to different working states. When the device needs to be installed on the inner wall of the tunnel, the first clamping post 2 is placed on the support frame 1. The second magnetic ring 11 at the bottom of the first clamping post 2 is magnetically attracted to the first magnetic ring 7 on the support frame 1, so as to install the first clamping post 2. Then, the support frame 1 installs the first clamping post 2 on the inner wall of the tunnel through the second threaded rod 10. When the device needs to be installed on the ground, the first clamping post 2 is placed on the ground and adsorbed on the ground through the suction cup 13, so as to install the first clamping post 2. When the device needs to be erected and installed on the ground, take out the third threaded rod 14, rotate the third threaded rod 14 to the threaded hole in the fixed column 12, and then adjust the swing frame 24. The swing frame 24 drives the movable plate 25 and the insertion plate 26 to swing. Move the movable plate 25, and the movable plate 25 drives the insertion plate 26 to move.

In the above working states, the second clamping post 3 can be placed on the first clamping post 2, and the first clamping post 2 and the second clamping post 3 are connected and installed through the first threaded rod 9. Starting the electronic level 4 can start working. When it is necessary to detect the temperature and humidity in the tunnel, start the motor 30. The motor 30 drives the transmission rod 31 to rotate. The transmission rod 31 drives the gear 32 to rotate. The gear 32 drives the rack 5 to move back and forth. The vertical plate 34 and the baffle 33 limit the moving track of the rack 5. The rack 5 moves the temperature and humidity sensor 6 through the connecting column 28 and the bolt 29. The L-shaped plate 22 and the L-shaped elastic plate 35 support and limit the temperature and humidity sensor 6. The temperature and humidity sensor 6 detects the temperature and humidity in the tunnel, so as to synchronously record the environmental parameters. When it is necessary to detect the influence of mechanical vibration on the tunnel structure during construction or operation, move the L-shaped rod 17. The L-shaped rod 17 drives the convex plate 18 and the fixed disk 16 to move. The L-shaped rod 17 drives the threaded cylinder 19 to move. The threaded cylinder 19 drives the fourth threaded rod 20 and the vibration sensor 21 to move. When the vibration sensor 21 needs to be attached to the wall, rotate the fourth threaded rod 20. The fourth threaded rod 20 moves in the threaded cylinder 19. The fourth threaded rod 20 drives the vibration sensor 21 to move, and the vibration sensor 21 is attached to the wall for detection. If the angle of the vibration sensor 21 needs to be adjusted, move the L-shaped rod 17. The L-shaped rod 17 drives the convex plate 18 to move. Move the convex plate 18 out of the adjacent groove, and then the L-shaped rod 17 can be rotated. After rotating the L-shaped rod 17 by 90 degrees, the convex plate 18 can be put into the adjacent groove again, so as to adjust the angle of the vibration sensor 21.
