[0026] As a technical optimization solution of the present utility model, guide plates 15 are fixedly connected to the tops of the left and right sides of the lengthening plate 5, guide grooves 16 that cooperate with the guide plates 15 are provided on the left and right sides inside the rotating plate 3, and the outer surface of the guide plate 15 is slidably connected to the inner surface of the guide groove 16.

[0027] In this embodiment, by providing the guide plate 15 and the guide groove 16, the lengthening plate 5 can be guided and limited.

[0028] As a technical optimization solution of the present utility model, the top of the screw rod 4 penetrates through the rotating plate 3 and is fixedly connected to a rotating handle 17, and the rotating handle 17 is circular.

[0031] In this embodiment, by providing the maintenance plate 18, it is convenient for the staff to regularly replace and maintain the parts inside the drive box 1.

[0032] As a technical optimization solution of the present utility model, a counterweight plate 19 is fixedly connected to the bottom of the concave plate 7, and the counterweight plate 19 is rectangular.

[0033] In this embodiment, by providing the counterweight plate 19, it is convenient for the concave plate 7 to always maintain a vertically downward state, improving the stability of the device.

[0034] Working principle: The staff fixes and installs the device at the designated position of the foundation pit monitoring point through the mounting plate 13, the mounting hole 14 and the screws. Then, the staff electrically connects the device to the mains power supply, so that the horizontal displacement monitor body 8 monitors the horizontal displacement of the foundation pit. At the same time, the monitoring data is transmitted to the peripheral display for the staff to view conveniently;

[0035] When it is necessary to adjust the monitoring depth of the horizontal displacement monitor body 8, the staff rotates the turning handle 17, so that the turning handle 17 drives the screw rod 4 to rotate threadedly on the inner surface of the extension plate 5, so that the extension plate 5 drives the guide plate 15 to slide on the inner surface of the guide groove 16, and, the extension plate 5 drives the rotating rod 6 to move, so that the rotating rod 6 drives the concave plate 7 to move, so that the concave plate 7 drives the horizontal displacement monitor body 8 to move downward to a suitable monitoring depth, thereby completing the adjustment of the monitoring depth of the horizontal displacement monitor body 8;

[0036] When it is necessary to adjust the monitoring position of the horizontal displacement monitor body 8, the staff powers on the plug of the servo motor 9 and starts the external controller of the servo motor 9, so that the output end of the servo motor 9 drives the driving gear 10 to rotate, the driving gear 10 drives the driven gear 11 to rotate, the driven gear 11 drives the rotating shaft 2 to rotate, the rotating shaft 2 drives the rotating plate 3 and the extension plate 5 to rotate. At the same time, the extension plate 5 drives the rotating rod 6 to rotate, so that the rotating rod 6 drives the concave plate 7 and the horizontal displacement monitor body 8 to rotate and move to a suitable monitoring position. While the rotating rod 6 drives the concave plate 7 and the horizontal displacement monitor body 8 to rotate, the horizontal displacement monitor body 8, the counterweight plate 19 and the concave plate 7 always maintain a vertically downward state under their own gravity, so that the horizontal displacement monitor body 8 can be normally monitored and used, thereby realizing the adjustment of the monitoring position of the horizontal displacement monitor body 8;

[0037] When it is necessary to perform maintenance on the horizontal displacement monitor body 8, the staff starts the external controller of the servo motor 9 again, so that the output end of the servo motor 9 drives the driving gear 10, the driven gear 11 and the rotating shaft 2 to rotate, so that the rotating shaft 2 drives the rotating plate 3 and the extension plate 5 to rotate vertically upward, so that the rotating rod 6 drives the concave plate 7 and the horizontal displacement monitor body 8 to rotate and move above the foundation pit. The principle is the same as above, so it will not be elaborated here, so as to facilitate the staff to perform maintenance on the horizontal displacement monitor body 8. The device is simple to operate and convenient for monitoring and use, so as to meet the monitoring and use needs of customers.
