[0002] Settlement monitoring is an important technical measure in engineering construction and an important basis for engineering design, construction and design changes.

[0003] When monitoring settlement, a settlement monitoring device is typically used for in-and-out measurements. Existing settlement monitoring devices consist of a conduit, a detection rod, and a steel plate. The conduit is inserted into the ground, and the detection tube is threaded through and secured to the guide rod. The steel plate is mounted on the side of the conduit away from the ground and has a through-hole for the conduit. A pointer assembly is installed on the side of the through-hole. The steel plate, mounted on the conduit, rises and falls with ground settlement, and the amount of settlement is displayed on the monitoring rod, reducing the error between the settlement measured by the detection rod and the actual amount.

[0004] However, since the steel plate is close to the ground, the value of the detection rod can only be read by lowering the head and squinting at the pointer and scale, which is very inconvenient and may also lead to reading errors. Utility Model Content

[0005] In order to reduce the error in reading the readings on the detection rod, the present application provides a settlement monitoring device.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-4 This application is described in further detail.

[0032] Example 1:

[0033] An embodiment of the present application discloses a settlement monitoring device.

[0034] Reference Figure 1 A settlement monitoring device includes a catheter 1, a steel plate 2, a reading component and a monitoring rod 4. The catheter 1 is plugged into the ground, the steel plate 2 is placed on the ground and is provided with a movable opening 21 connected to the catheter 1. In this embodiment, the axis of the movable opening 21 is coaxial with the axis of the catheter 1; and when the catheter 1 and the steel plate 2 are installed at the location to be monitored, there is a gap between the outer wall of the catheter 1 and the inner wall of the movable opening 21, so that when the steel plate 2 is tilted, there is space for the catheter 1 to move, and the upper surface of the catheter 1 is flush with the upper surface of the steel plate 2.

[0035] Reference Figure 2The monitoring rod 4 is passed through the movable hole and is connected to the catheter 1 through the clamping assembly 5. The clamping assembly 5 includes an unlocking member 51, a second clamping block 52 and a second spring 53. A second movable groove 11 is provided on the inner wall of the catheter 1. The second clamping block 52 is movably installed in the second movable groove 11; the second clamping block 52 is provided with a first guide surface 54 and a second guide surface 55 on opposite sides. The first guide surface 54 is located on the side of the clamping block away from the ground, and the distance between the first guide surface 54 and the second guide surface 55 gradually increases from the side away from the second movable groove 11 to the side close to the second movable groove 11.

[0036] The second spring 53 is installed between the second clamping block 52 and the inner wall of the second movable groove 11. The elastic force of the second spring 53 drives the second clamping block 52 to move toward the side away from the second movable groove 11. The outer wall of the detection rod is provided with a second clamping groove 41. When the monitoring rod 4 is inserted into the inside of the catheter 1, the detection rod abuts against the first guide surface 54 and guides the second clamping block 52 into the second movable groove 11, so that the monitoring rod 4 passes through the second movable groove 11 smoothly. When the second clamping groove 41 and the second movable groove 11 are arranged opposite each other, the second clamping block 52 is inserted into the second clamping groove 41 under the elastic force of the second spring 53, thereby completing the fixation between the detection rod and the catheter 1.

[0037] A guide block 43 is fixed to the outer wall of the detection rod, and a guide groove 12 is opened on the inner wall of the catheter 1 for the guide block 43 to slide. The cooperation between the guide block 43 and the guide groove 12 can improve the rapid alignment of the second movable groove 11 and the second positioning groove 23, thereby improving the installation efficiency of the detection rod and the catheter 1.

[0038] The unlocking member 51 includes a third spring 512 and an unlocking rod 511. An unlocking slot 42 is provided at one end of the detection rod. The extension direction of the unlocking slot 42 is the same as the extension direction of the unlocking rod 511. The unlocking slot 42 is communicated with the second clamping slot 41. The second clamping block 52 is passed through the second clamping slot 41 and enters the second movable slot 11; the unlocking rod 511 is movably installed in the unlocking slot 42, and the third spring 512 is installed between the inner wall of the unlocking slot 42 and the unlocking rod 511. The elastic force of the third spring 512 is used to drive the unlocking rod 511 to move toward the side away from the unlocking slot 42.

[0039] When it is necessary to cancel the connection between the unlocking rod 511 and the catheter 1, the unlocking rod 511 is moved toward the side away from the unlocking groove 42 so that it abuts against the first guide surface 54, so that the second clamping block 52 can be disengaged from the unlocking groove 42 under the guidance of the first guide surface 54; at this time, the monitoring rod 4 moves toward one side of the catheter 1, and the second guide surface 55 abuts against the inner wall of the second clamping groove 41, so that the second clamping block 52 can completely enter the second movable groove 11 under the guidance of the second guide surface 55, that is, the fixation between the detection rod and the catheter 1 is canceled.

[0040] Reference Figure 3 , a cover plate 13 is hingedly connected to the end of the conduit 1 away from the ground, and the cover plate 13 is used to cover the opening of the conduit 1; in this embodiment, the cover plate 13 is provided with a first magnetic member, and the conduit 1 is provided with a second magnetic member. The cooperation of the first magnetic member and the second magnetic member can enable the cover plate 13 to cover the opening of the conduit 1 under normal circumstances, thereby reducing the situation where rainwater and dust enter the interior of the conduit 1 after the monitoring rod 4 is removed from the conduit 1; so as to facilitate the installation of the monitoring rod 4 and the conduit 1 next time.

[0041] Reference Figure 1 and Figure 3 The reading assembly includes a resilient shrink ring 31 and two positioning blocks 32. The shrink ring 31 is elastic. The steel plate 2 has two mounting slots 22, located on opposite sides of the movable opening 21. The two positioning blocks 32 are inserted into the two mounting slots 22. Rigid rods 33 are fixed to the two positioning blocks 32, each of which is fixed to the shrink ring 31. When the positioning blocks 32 are inserted into the mounting slots, the shrink ring 31 is sleeved onto the outer wall of the monitoring rod 4.

[0042] By setting the rigid rod 33, when both positioning blocks 32 are inserted into the installation groove 22, the shrink ring 31 is set parallel to the two positioning blocks 32, thereby improving the accuracy of reading the finger using the shrink ring 31 sleeved on the outer wall of the monitoring rod 4.

[0043] The implementation principle of a settlement monitoring device in Example 1 of the present application is as follows:

[0044] When detecting the settlement of the steel plate 2, the detection rod is inserted into the inner wall of the conduit 1, and the detection rod and the conduit 1 are fixed by the insertion and cooperation of the second clamping block 52 and the second clamping groove 41; then the shrinking ring 31 is sleeved on the outer wall of the detection rod, and then the two positioning blocks 32 are respectively inserted into the two installation grooves 22, so that the shrinking ring 31 and the surface of the steel plate 2 can be at the same level to maintain the accuracy of the measurement value of the steel plate 2 each time; then the detection rod is unfixed from the conduit 1, and the shrinking ring 31 and the detection rod are taken out; by reading the reading at the position where the shrinking ring 31 is sleeved on the detection rod, subtracting the reading when the steel plate 2 and the conduit 1 are first installed, the settlement monitoring is completed, and the situation where the value of the detection rod can only be read by lowering the head and squinting at the pointer and scale is reduced, thereby improving the accuracy of the value.

[0045] Example 2:

[0046] Example 2 of the present application improves a sedimentation monitoring device.

[0047] Reference Figure 4The difference between this embodiment 2 and embodiment 1 is that: the steel plate 2 is provided with two positioning grooves 23, and the two positioning blocks 32 are respectively inserted into the two positioning grooves 23; the positioning block 32 is provided with a first movable groove 321, and a first clamping block 34 is movably installed in the first movable groove 321, and the first clamping block 34 is provided with a third guide surface 36 for guiding the first clamping block 34 into the first movable groove 321; a first spring 35 is provided between the first clamping block 34 and the inner wall of the first movable groove 321, and the elastic force of the first spring 35 drives the first movable groove 321 to move toward the side away from the first movable groove 321.

[0048] The inner wall of the positioning groove 23 is provided with a first clamping groove 24 for the first clamping block 34 to be inserted into. The cooperation between the first clamping block 34 and the first clamping groove 24 can fix the positioning block 32 to the steel plate 2 to ensure that both positioning blocks 32 are inserted into the positioning groove 23, thereby reducing the situation where one of the positioning blocks 32 is not fully inserted into the positioning groove 23, resulting in inaccurate positioning of the winding ring, and improving accuracy.

[0049] The positioning block 32 is provided with a pressing groove 322, in which a pressing rod 38 is movably mounted. The pressing groove 322 is connected to the first movable groove 321 via a connecting groove 323. A connecting rod 37 is mounted in the connecting groove 323. The two ends of the connecting rod 37 are respectively connected to the pressing rod 38 and the first clamping block 34. When the positioning block 32 is removed from the steel plate 2, by pressing the pressing rod 38, both the first positioning block 32 and the pressing rod 38 can be moved toward the side away from the first clamping groove 24, thereby canceling the connection between the first clamping block 34 and the first clamping groove 24, so that the shrink ring 31 and the monitoring rod 4 can be removed simultaneously. This structure is simple and improves the efficiency of disassembly between the positioning rod and the steel plate 2.

[0050] The above are preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
