[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As shown in Figures 1, 3, 4, and 5, a slurry height monitoring device of the utility model is disclosed. The mounting plate 1 has fixing holes 2 at each of its four top corners. The mounting plate 1 is installed on the top of a wall panel via the fixing holes 2 and fixing bolts. A sliding groove 3 is fixedly installed on the mounting plate 1. A limit rod 4 is fixedly connected to the inner wall of the sliding groove 3, and a servo motor 5 is fixedly connected to the outer wall of the sliding groove 3. One end of a lead screw 6 is fixedly connected to the output end of the servo motor 5 via a coupling. The other end of the lead screw 6 is fixedly connected to the inner ring of a bearing 7. A slider 8 is movably connected to the lead screw 6, and a limit hole 9 is provided on the side of the slider 8. The shape and size of the limiting hole 9 match the limiting rod 4. The slider 8 is slidably connected to the limiting rod 4 through the limiting hole 9, which facilitates the limiting of the slider 8 and improves the stability of the slider 8 during movement. A threaded hole 10 is provided at the center of the side of the slider 8. The threaded hole 10 is connected to the lead screw 6. The threaded hole 10 is engaged with the lead screw 6 through the thread. The servo motor 5 drives the movement and rotation of the lead screw 6 in the slide groove 3. The rotating lead screw 6 will cause the slider 8 to move horizontally on the lead screw 6 through the threaded hole 10, thereby causing the monitoring device body 14 to move horizontally and improving the monitoring range of the monitoring device body 14.

[0020] An electric push rod 11 is fixedly connected to the bottom of the slider 8. The telescopic end of the electric push rod 11 is fixedly connected to the mounting base 12. The monitoring device body 14 is movably connected to the mounting base 12. The electric push rod 11 can drive the monitoring device body 14 to rise and fall, further expanding the monitoring range of the monitoring device body.

[0021] The mounting base 12 has positioning holes 13 on both sides, and the monitoring device body 14 has mounting holes 15 on both sides of its top. A positioning spring 16 is fixedly connected inside the mounting hole 15, and a positioning block 17 is fixedly connected to one end of the positioning spring 16. The operator can press the positioning block 17, which compresses the positioning spring 16 and retracts it into the mounting hole 15. Align the positioning block 17 with the corresponding positioning hole 13, insert the positioning block 17 into the inner wall on both sides of the mounting base 12, and gently push the monitoring device body 14 upward. Under the reaction force of the positioning spring 16, the positioning block 17 pops out from the positioning hole 13, and the monitoring device body 14 can be installed on the mounting base 12. The operator can remove the monitoring device body 14 from the mounting base 12 by following this operation, which is convenient for maintenance of the monitoring device.

[0022] Working principle: The mounting plate 1 is installed on the top of the wall panel through the fixing holes 2 and fixing bolts. Press the positioning blocks 17 on both sides of the monitoring device body 14 and align them with the positioning holes 13 to install the monitoring device body 14 into the mounting base 12. After installation, start the servo motor 5 and the electric push rod 11. The output end of the servo motor 5 drives the lead screw 6 to rotate, which in turn drives the slider 8 to move in the slide groove 3. The telescopic end of the electric push rod 11 drives the mounting base 12 and the monitoring device body 14 to move up and down, thereby making the monitoring device body 14 move up and down horizontally at the same time, increasing the monitoring range of the monitoring device body 14. When the monitoring device body 14 malfunctions, press the positioning blocks 17 on both sides of the mounting base 12 again to retract them into the mounting holes 15. Gently pull down the monitoring device body 14 to disconnect the positioning blocks 17 from the positioning holes 13, and the monitoring device body 14 can be removed, thus completing the disassembly of the monitoring device body 14. This facilitates timely maintenance by the staff and improves the monitoring effect.

[0023] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
