[0002] During the construction process, it is necessary to detect the ground subsidence in the construction area. Ground subsidence, also known as ground subsidence or ground subsidence, is a local downward movement caused by the consolidation and compression of loose underground strata, which leads to a lowering of the elevation of the earth's surface.

[0041] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0042] like Figure 1-Figure 7As shown, an embodiment of the present invention provides a ground settlement monitoring system, including a main support rod 1, a settlement ring 2, a rotating mechanism 3 and a detection mechanism. Among them, the outer wall of the main support rod 1 is provided with a guide structure and buried in the ground, and the axial direction of the main support rod 1 is the same as the vertical direction. The settlement ring 2 is buried in the ground and is slidably sleeved outside the main support rod 1 along the axial direction of the main support rod 1, and the inner wall of the settlement ring 2 is provided with a receiving groove. The rotating mechanism 3 is arranged in the receiving groove and connected to the guiding structure. When the settlement ring 2 moves along the axial direction of the main support rod 1, the rotating mechanism 3 moves around the axial circumference of the main support rod 1 along the trajectory of the guiding structure. The detection mechanism can detect the rotation angle of the rotating mechanism 3. It should be noted that the rotating mechanism 3 is arranged in the receiving groove. When the settlement ring 2 moves along the axial direction of the main support rod 1, the rotating mechanism 3 will also move simultaneously with the settlement ring 2 along the axial direction of the main support rod 1. The guiding structure realizes that the rotating mechanism 3 rotates while moving along the axial direction of the main support rod 1.

[0043] Specifically, when the ground settles, the settling ring 2 descends along the axis of the main support rod 1, driving the rotating mechanism 3 to descend at the same time. When the rotating mechanism 3 descends, the guide structure of the main support rod 1 can cause the rotating mechanism 3 to rotate.

[0044] The ground settlement monitoring system converts the linear movement of the settlement ring 2 into the rotation of the rotating mechanism 3 by arranging the rotating mechanism 3 in the accommodating groove and connecting the rotating mechanism 3 with the guide structure. By converting the linear movement into rotation, the tiny linear displacement can be amplified, and then the rotation angle of the rotating mechanism 3 is detected to accurately obtain the tiny linear displacement of the settlement ring 2, thereby accurately monitoring the tiny displacement of the ground settlement.

[0045] Optionally, the rotating mechanism 3 includes a rotating ring 31 and a transmission member 32, the rotating ring 31 is arranged in the accommodating groove and rotatably sleeved on the outside of the main support rod 1, and the rotating ring 31 is transmission-connected to the outer wall of the main support rod 1 through the transmission member 32. When the settlement ring 2 moves, it can drive the rotating ring 31 to move along the axial direction of the main support rod 1, and the guide structure of the main support rod 1 can rotate the rotating ring 31 through the transmission member 32. The rotating ring 31 is connected to the guide structure of the main support rod 1 through the transmission member 32, so that when the settlement ring 2 drives the rotating ring 31 to move along the axial direction of the main support rod 1, the rotating ring 31 rotates under the action of the guide structure of the main support rod 1, and the displacement of the ground sinking is obtained by detecting the rotation angle of the rotating ring 31.

[0046] Specifically, Figure 3-Figure 5As shown, the rotating ring 31 is provided with a ring frame 311, and the ring frame 311 is in sliding contact with the groove wall of the accommodating groove; the transmission member 32 is provided as a follower ball (which can be a steel ball), and the guide structure is a spiral groove 111, and a part of the follower ball is provided in the spiral groove 111, and the other part is provided in the ring frame 311. When the settling ring 2 moves along the axis direction of the main support rod 1, the groove wall of the accommodating groove presses the ring frame 311, so that the rotating ring 31 has a force to move along the axis direction of the main support rod 1, and the force causes the follower ball to displace along the trajectory of the spiral groove 111, that is, the follower ball rotates around the spiral groove 111, and drives the rotating ring 31 to rotate when it moves linearly along the axis direction of the main support rod 1. In this structure, a spiral groove 111 is provided on the outer wall of the main support rod 1, and a follower ball is provided in the spiral groove 111 and the ring frame 311, so that when the sedimentation ring 2 drives the rotating ring 31 to move along the axial direction of the main support rod 1, the main support rod 1 can cause the rotating ring 31 to rotate.

[0047] In this embodiment, the sinking ring 2 descends along the axial direction of the main support rod 1, and the ring frame 311 is fixedly arranged on the upper end surface of the rotating ring 31 and slidably abuts against the upper groove wall of the accommodating groove.

[0048] Optionally, the cross section of the ring frame 311 can be set to a square ring shape or a circular ring shape, and the square ring shape of the ring frame 311 is more firmly connected to the rotating ring 31 .

[0049] In order to improve the smoothness of rotation of the rotating ring 31, the rotating ring 31 is also provided with a plurality of support plates 312. The plurality of support plates 312 are circumferentially arranged on the end surface of the ring frame 311 provided on the rotating ring 31. When the sinking ring 2 moves along the axial direction of the main support rod 1, the groove wall of the accommodating groove can be pressed against the ring frame 311 and the plurality of support plates 312, so that the rotating ring 31 is subjected to more uniform force and rotates more smoothly.

[0050] Specifically, the support plate 312 includes a vertical plate and a horizontal plate which are vertically connected to each other. The vertical plate is fixedly connected to the rotating ring 31, and the horizontal plate is fixedly connected to one end of the vertical plate which is away from the rotating ring 31 and is slidably abutted against the groove wall of the accommodating groove. This structure can increase the contact area between the support plate 312 and the accommodating groove by abutting the groove wall of the accommodating groove with the horizontal plate, thereby improving stability.

[0051] In this embodiment, three support plates 312 are provided. The three support plates 312 and one ring frame 311 are evenly distributed on the rotating ring 31 circumference. The three support plates 312 and one ring frame 311 constitute four support points that abut against the groove wall of the accommodating groove.

[0052] In order to reduce the wear of the ring frame 311 and the support plate 312, as Figure 6-Figure 7As shown, the groove wall of the accommodating groove is provided with a groove arranged around the axis circumference of the main support rod 1, and a plurality of balls 12 abutting against each other are arranged in the groove. The cross plates of the ring frame 311 and the support plate 312 are both in abutment with the balls 12. By arranging the balls 12, this structure makes the cross plates of the ring frame 311 and the support plate 312 abut against the balls 12, so that the rotating ring 31 rotates more smoothly.

[0053] In order to further improve the rotation stability of the rotating ring 31, the ground subsidence monitoring system also includes a plurality of follower rollers 5, which are arranged in the accommodating groove and connected to the lower groove wall of the accommodating groove. The outer wall of the follower roller 5 rolls with the inner wall of the rotating ring 31. The follower roller 5 can support the rotating ring 31 to prevent its deformation, and can drive the follower roller 5 to rotate at the same time when the rotating ring 31 rotates, thereby reducing the wear of the rotating ring 31.

[0054] Optionally, the detection mechanism includes a detection roller 4 and an angle sensor, the detection roller 4 is arranged in the accommodating groove and connected to the lower groove wall of the accommodating groove, and the outer wall of the detection roller 4 and the inner wall or outer wall of the rotating ring 31 are rotationally fitted, and the rotating ring 31 can drive the detection roller 4 to rotate when it rotates. The angle sensor is arranged on the detection roller 4 and is used to detect the rotation angle of the detection roller 4. This structure can transmit the rotation angle of the rotating ring 31 to the detection roller 4 by rotationally fitting the outer wall of the detection roller 4 with the inner wall or outer wall of the rotating ring 31, and detect the rotation angle of the detection roller 4 through the angle sensor, thereby making the detection more convenient.

[0055] In this embodiment, the diameter of the detection roller 4 is smaller than the diameter of the rotating ring 31 , so that when the rotating ring 31 drives the detection roller 4 to rotate, the rotation angle can be further enlarged, thereby improving the detection accuracy.

[0056] Optionally, the detection mechanism includes two detection rollers 4 and angle sensors arranged on the two detection rollers 4. By arranging the two detection rollers 4 to simultaneously detect the rotation angle of the rotating ring 31, failure caused by a failure of one detection roller 4 or the angle sensor can be avoided, and the two detection rollers 4 can also be compared with each other. If the angle data detected by the two angle sensors are the same, it indicates that the ground subsidence monitoring system is operating normally. If the angle data are different, it indicates that a failure has occurred.

[0057] In this embodiment, the detection roller 4 is disposed on the outer side of the rotating ring 31 and is rotatably fitted with the outer wall of the rotating ring 31 , and can assist in supporting the rotating ring 31 together with the follower roller 5 to prevent the rotating ring 31 from deformation.

[0058] Optionally, the guiding structure of the main support rod 1 includes two strip protrusions 11 with the same rotation direction protruding from the outer wall of the main support rod 1, and the two strip protrusions 11 are spaced apart along the axial direction of the main support rod 1 to form a spiral groove 111. This structure facilitates processing by arranging the strip protrusions 11 on the outer wall of the main support rod 1; and the main support rod 1 can be selected as a steel pipe, and the wall thickness of the steel pipe can be appropriately thinned when the use requirements are met, which can effectively reduce the cost.

[0059] Optionally, refer to Figure 1-Figure 2 In order to prevent the soil on the outside from entering the spiral groove 111 and affecting normal operation, the ground settlement monitoring system also includes two outer sleeves 6, which are both sleeved outside the main support rod 1 and respectively arranged at the two ends of the settlement ring 2 along the axial direction of the main support rod 1, and the spiral groove 111 is located in the two outer sleeves 6.

[0060] Specifically, a closed ring is extended inwardly from the inner wall of the end of the outer sleeve 6 away from the settlement ring 2 , and the closed ring can effectively prevent the soil on the outside from entering the outer sleeve 6 .

[0061] In order to increase the friction between the sedimentation ring 2 and the soil, a plurality of fins 21 are provided on the sedimentation ring 2 .

[0062] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the embodiments here.
