[0028] In some optional embodiments, as shown in Figure 1 、 Figure 2 , the limiting piece includes plug ring 2, limiting ring 3 and cover 6, the plug ring 2 is vertically arranged through the base 1, and the plug rod 4 is arranged in the plug ring 2, so that the plug rod 4 can slide up and down in the plug ring 2 and rotate in the plug ring 2, and the cover 6 is detachably connected with the limiting ring 3.The limiting ring 3 is arranged at the upper end of the plug ring 2, and the limiting ring 3 can limit the plug rod 4 to slide up and down in the plug ring 2, and optionally, a protrusion can be arranged at the top end of the plug rod 4, and a ring groove is arranged at the middle part of the limiting ring 3, the protrusion is inserted into the ring groove, so that the plug rod 4 cannot move up and down in the plug ring 2.In the embodiment, the plug rod 4 can be smoothly inserted into the ground when the screw groove on the plug rod 4 is screwed, and the base 1 is driven to move downward, and after being fixed, the cover 6 is installed on the limiting ring 3 to limit the plug rod 4 to rotate in the plug ring 2, and optionally, a protrusion can be arranged on the cover 6, and the protrusion is inserted into the screw groove, so that the plug rod 4 cannot rotate in the plug ring 2.

[0029] In some optional embodiments, the limiting ring 3 is provided with external threads, and the cover 6 is provided with internal threads, and the detachable connection of the limiting ring 3 and the cover 6 is realized through the cooperation of the external threads and the internal threads.

By providing the threaded groove 5, when the insertion rod 4 is inserted into the ground by rotation, the soil will fill the entire threaded groove 5, which not only expands the contact area between the outer wall of the insertion rod 4 and the soil, but also helps to improve the stability of the entire insertion rod 4 fixing structure.

[0031] In some alternative embodiments, such as Figures 1 to 3 As shown, the detection assembly also includes a base plate 11, which is fixedly installed at the lower end of the second upright 9. A square tube 19 is provided on the base plate 11, and a sliding rod 20 is vertically slidably inserted into the square tube 19. At this time, the sliding rod 20 can slide up and down inside the square tube 19. Since the cross-section of the square tube 19 is square, the sliding rod 20 cannot rotate inside the square tube 19.

[0032] In some alternative embodiments, such as Figure 1 As shown, the detection assembly also includes a side plate 12, which is fixedly connected to the second upright 9, and the triggering assembly is movably mounted on the side plate 12.

[0033] In some alternative embodiments, such as Figure 3 As shown, a sliding groove 13 is provided on the side plate 12. Multiple sets of slot plates 14 are provided on the inner wall of the sliding groove 13 in the vertical direction. The trigger component is locked on the slot plate 14, which makes it convenient to disassemble and assemble the trigger component. At the same time, the installation position of the trigger component can be adjusted to adjust the judgment height of the foundation settlement.

[0034] In some alternative embodiments, such as Figure 3 As shown, the triggering assembly includes a locking block 15, a circuit board 16, and a contact sensor 17. The locking block 15 is snapped onto the inner wall of the slot plate 14. The circuit board 16 is installed in the locking block 15, and the contact sensor 17 is located on the circuit board 16. A contact plate 23 for triggering the contact sensor 17 is provided on the slide rod 20. By setting a simple connection between the locking block 15 and the slot plate 14, the installation position of the locking block 15 can be arbitrarily adjusted. Thus, the locking block 15 can be installed in any slot plate 14, and the height of the locking block 15 changes accordingly. Consequently, the height of the contact sensor 17 also changes, thereby adjusting the judgment height for foundation settlement. Optionally, the contact sensor 17 can be a capacitive contact sensor, an inductive contact sensor, an infrared proximity sensor, etc. It is understood that the contact plate 23 uses a component with a corresponding detection principle.

[0035] In some alternative embodiments, such as Figure 3 As shown, the outer wall of the contact plate 23 is slidably connected to the inner wall of the slide groove 13, thereby limiting the contact plate 23 within the slide groove 13.

[0036] In some alternative embodiments, such as Figure 3As shown, a limiting plate 22 is provided at the upper end of the slide bar 20, and a contact plate 23 is provided on the limiting plate 22. The size of the limiting plate 22 is larger than the size of the square tube 19. In this way, under the limiting action of the limiting plate 22, the slide bar 20 will not fall off the base plate 11 when it moves down.

[0037] In some alternative embodiments, such as Figure 3 As shown, an alarm 18 is provided at the lower end of the circuit board 16. In this embodiment, when the foundation settles, the detection head 21 will slide downwards along with the slide rod 20 and the limiting plate 22. At this time, the distance between the contact plate 23 and the contact sensor 17 will get closer and closer. When the contact plate 23 touches the contact sensor 17, it indicates that the settlement is serious. At this time, the alarm 18 will immediately sound to remind the surrounding personnel. At the same time, since the base 1 is installed far away from the foundation, the foundation settlement will not affect the base 1, and the detection device will not move synchronously with the foundation.
