Description

Technical Field

[0001] The present invention belongs to the technical field of ground settlement monitoring, and specifically relates to an embedded ground settlement monitoring device. Background Art

[0002] A settlement monitoring device is used to monitor the distance of settlement of a building or structure. By deploying it at the location that can most sensitively reflect the settlement change of the building, the settlement change can be shown, and corresponding measures can be taken in advance.

[0003] Most of the existing settlement monitoring devices include a positioning rod and a settlement ring sleeved outside the positioning rod. By inserting the positioning rod into the ground to be monitored, the settlement ring is pressed above the ground. When the ground below the settlement ring settles, the settlement ring moves down together with the settled ground. At this time, measuring the downward movement distance of the settlement ring can obtain the ground settlement amount. However, this ground settlement monitoring method is relatively traditional. When the fit between the settlement ring and the positioning rod is relatively tight, the friction force between the settlement ring and the positioning rod will be large, resulting in the settlement ring being unable to move down smoothly when the ground settles. When the fit between the settlement ring and the positioning rod is relatively loose, the entire weight of the settlement ring will press on the ground, causing unnecessary pressure on the ground and thus affecting the accuracy of the measurement result. Summary of the Invention

[0004] Aiming at the deficiencies of the above-mentioned existing technologies, the technical problem to be solved by the embodiments of the present invention is to provide an embedded ground settlement monitoring device.

[0005] To solve the above technical problem, the present invention provides the following technical solutions:

[0006] An embedded ground settlement monitoring device includes a positioning tube, a settlement ring, a detection component, a locking component, and an unlocking component.

[0007] The settlement ring is movably sleeved outside the positioning tube.

[0008] The locking component is installed on the outer wall of the positioning tube. When the settlement ring contacts the ground for settlement monitoring, the locking component is used to lock the settlement ring and the positioning tube into one body.

[0009] The unlocking component is arranged inside the positioning tube.

[0010] The detection component is arranged on the settlement ring and is used to detect the ground below the settlement ring. When the detection component detects that the ground below the settlement ring has settled, the unlocking component releases the locked state of the settlement ring.

[0011] As a further improvement of the present invention: a battery is arranged inside the positioning tube.

[0012] The unlocking assembly includes an electromagnet, a piston plate and a permanent magnet.

[0013] The electromagnet and the piston plate are arranged inside the positioning tube. Among them, the electromagnet is fixedly installed on the inner wall of the positioning tube, the piston plate is arranged above the electromagnet and can slide inside the positioning tube, and the permanent magnet is fixedly arranged at the bottom of the piston plate.

[0014] The locking assembly includes a strip-shaped airbag and an air pipe.

[0015] The strip-shaped airbag is installed on the outer wall of the positioning tube and is distributed along the length direction of the positioning tube. One end of the air pipe is communicated with the strip-shaped airbag, and the other end passes through the positioning tube and extends between the electromagnet and the piston plate.

[0016] As a further improvement of the present invention: two sets of oppositely distributed chutes are provided on the side wall of the positioning tube.

[0017] The settling ring is provided with through holes. A connecting rod is fixedly arranged on the inner wall of the settling ring. The connecting rod horizontally penetrates the positioning tube through the two chutes. A second conductive rod and a first conductive rod are embedded inside the connecting rod. One ends of the second conductive rod and the first conductive rod extend into the through holes. The other end of the second conductive rod is connected to the electromagnet through a second wire, and the other end of the first conductive rod is connected to the battery through a first wire.

[0018] The detection assembly includes a detection rod and a conductive sheet. The detection rod vertically penetrates the through hole, and the conductive sheet is arranged on the side wall of the detection rod.

[0019] As a further improvement of the present invention: the upper part of the piston plate is connected to the inner top wall of the positioning tube through an elastic member, and the elastic member is used to provide elastic support for the piston plate.

[0020] As a further improvement of the present invention: the elastic member is a spring or a metal elastic sheet.

[0021] As a further improvement of the present invention: a retaining ring is also fixedly arranged on the inner wall of the positioning tube, and the retaining ring is located between the electromagnet and the piston plate to limit the piston plate.

[0022] As a further improvement of the present invention: scales are arranged on the outer wall of the positioning tube.

[0023] Compared with the prior art, the beneficial effects of the present invention are:

[0024] In an embodiment of the present invention, when monitoring land subsidence, the lower end of the positioning pipe can be inserted into the ground to be monitored, so that the bottom of the settlement ring contacts the ground. At this time, the locking assembly locks the settlement ring and the positioning pipe together to prevent the settlement ring from pressing the ground under its own gravity, thereby causing the ground to sink. When the ground under the settlement ring subsides, the detection assembly detects the land subsidence phenomenon. At this time, the unlocking assembly releases the locked state of the settlement ring, and the settlement ring slides down along the outside of the positioning pipe under its own gravity until the settlement ring contacts the ground again, and the locking assembly locks the settlement ring again. At this time, the staff can measure the sliding distance of the settlement ring along the outside of the positioning pipe, so as to obtain the amount of land subsidence. Compared with the prior art, when monitoring land subsidence, the interference of the self-gravity of the settlement ring can be excluded, and at the same time, the settlement ring can slide down flexibly along the outside of the positioning pipe after the ground subsides, thereby improving the accuracy of the measurement result of the land subsidence amount and the sensitivity during the land subsidence monitoring process.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The technical solutions of the present invention will be further described in detail below in conjunction with the specific embodiments.

[0031] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0032] See also Figure 1 , Figure 2 as well as Figure 4 The present embodiment provides an embedded ground settlement monitoring device, including a positioning tube 10, a settlement ring 20, a detection component 30, a locking component 40 and an unlocking component 50. The settlement ring 20 is movably sleeved on the outside of the positioning tube 10, and the locking component 40 is installed on the outer wall of the positioning tube 10. When the settlement ring 20 contacts the ground for settlement monitoring, the locking component 40 is used to lock the settlement ring 20 and the positioning tube 10 as a whole. The unlocking component 50 is arranged inside the positioning tube 10, and the detection component 30 is arranged on the settlement ring 20 for detecting the ground below the settlement ring 20. When the detection component 30 detects that the ground below the settlement ring 20 has settled, the unlocking component 50 releases the locking state of the settlement ring 20.

[0033] When monitoring ground subsidence, the lower end of the positioning tube 10 can be inserted into the ground to be monitored so that the bottom of the settlement ring 20 contacts the ground. At this time, the locking assembly 40 is used to lock the settlement ring 20 and the positioning tube 10 as a whole to prevent the settlement ring 20 from pressing the ground under its own gravity, thereby causing the ground to sink. When the ground below the settlement ring 20 settles, the detection assembly 30 detects the ground settlement phenomenon. At this time, the unlocking assembly 50 releases the locking state of the settlement ring 20. The settlement ring 20 slides down along the outside of the positioning tube 10 under the action of its own gravity until the settlement ring 20 contacts the ground again. The locking assembly 40 locks the settlement ring 20 again. At this time, the staff can measure the sliding distance of the settlement ring 20 along the outside of the positioning tube 10, thereby obtaining the amount of ground settlement.

[0034] See also Figure 1 as well as Figure 3 In one embodiment, a battery (not shown in the figure) is arranged inside the positioning tube 10, and the unlocking component 50 includes an electromagnet 501, a piston plate 502 and a permanent magnet (not shown in the figure). The electromagnet 501 and the piston plate 502 are arranged inside the positioning tube 10, wherein the electromagnet 502 is fixedly mounted on the inner wall of the positioning tube 10, the piston plate 502 is arranged above the electromagnet 501 and can slide inside the positioning tube 10, and the permanent magnet is fixedly arranged at the bottom of the piston plate 502. The locking component 40 includes a strip airbag 401 and an air pipe 402, the strip airbag 401 is mounted on the outer wall of the positioning tube 10 and distributed along the length direction of the positioning tube 10, one end of the air pipe 402 is connected to the strip airbag 401, and the other end passes through the positioning tube 10 and extends between the electromagnet 501 and the piston plate 502.

[0035] When the ground under the settlement ring 20 does not settle, the strip-shaped airbag 401 is in an inflated state, and then expands and tightens the inner wall of the settlement ring 20 to lock the settlement ring 20, so that the gravity of the settlement ring 20 will not be applied to the ground below it, and thus will not exert pressure on the ground, so that the ground will not sink due to the pressing of the settlement ring 20; when the detection component 30 detects that the ground under the settlement ring 20 settles, the battery supplies power to the electromagnet 501, and the electromagnet 501 generates a magnetic repulsive force, which then pushes the permanent magnet to move the piston plate 502 upward along the inside of the positioning tube 10. When the piston plate 502 moves upward, the air inside the strip-shaped airbag 401 is pumped into the inside of the positioning tube 10 through the air pipe 402, so as to drive the strip-shaped airbag 401 to deflate. When the strip-shaped airbag 401 deflates, it no longer expands and tightens the inner wall of the settlement ring 20, thus releasing the locked state of the settlement ring 20, enabling the settlement ring 20 to slide downward along the outside of the positioning tube 10, thereby completing the measurement of the ground settlement amount.

[0036] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In one embodiment, two groups of oppositely distributed sliding grooves 101 are formed on the side wall of the positioning tube 10, through holes 202 are formed on the settlement ring 20, a connecting rod 201 is fixedly arranged on the inner wall of the settlement ring 20, the connecting rod 201 horizontally penetrates through the positioning tube 10 from the two groups of sliding grooves 101, a second conductive rod 205 and a first conductive rod 206 are buried inside the connecting rod 201, one ends of the second conductive rod 205 and the first conductive rod 206 extend into the inside of the through hole 202, the other end of the second conductive rod 205 is connected to the electromagnet 501 through a second wire 204, the other end of the first conductive rod 206 is connected to the battery through a first wire 203, the detection component 30 includes a detection rod 301 and a conductive sheet 302, the detection rod 301 vertically penetrates through the through hole 202, and the conductive sheet 302 is arranged on the side wall of the detection rod 301.

[0037] When the ground under the settlement ring 20 does not settle, the bottom of the detection rod 301 acts on the ground, so that the conductive sheet 302 on the side wall of the detection rod 301 is located above the second conductive rod 205 and the first conductive rod 206, and the conductive sheet 302 does not contact the second conductive rod 205 and the first conductive rod 206. The electromagnet 501 is in a power-off state, and the piston plate 502 is in a state of pressing the air inside the strip-shaped airbag 401. The strip-shaped airbag 401 expands and then tightens the settlement ring 20 to achieve the locking of the settlement ring 20, so as to prevent the settlement ring 20 from pressing the ground and causing the ground to sink. When the ground under the settlement ring 20 settles, the detection rod 301 moves down synchronously with the settling ground. The detection rod 301 moves down relative to the settlement ring 20, thereby driving the conductive sheet 302 to move down. When the conductive sheet 302 moves down, it synchronously contacts one end of the second conductive rod 205 and the first conductive rod 206. At this time, the battery supplies power to the electromagnet 501 through the first wire 203, the first conductive rod 206, the conductive sheet 302, the second conductive rod 205, and the second wire 204. The electromagnet 501 generates a magnetic repulsive force, thereby pushing the permanent magnet under the piston plate 502 to drive the piston plate 502 to move up along the inside of the positioning tube 10, so as to extract the air inside the strip-shaped airbag 401 into the positioning tube 10 through the air tube 402, causing the strip-shaped airbag 401 to deflate, and then releasing the locking of the settlement ring 20, so that the settlement ring 20 can slide down along the outside of the positioning tube 10. When the settlement ring 20 slides down along the outside of the positioning tube 10, the connecting rod 201 slides down synchronously along the inside of the two sliding grooves 101. At the same time, the detection rod 301 moves up relative to the settlement ring 20, thereby driving the conductive sheet 302 to move up. When the settlement ring 20 contacts the settled ground again, the conductive sheet 302 separates from the second conductive rod 205 and the first conductive rod 206, and the battery can no longer supply power to the electromagnet 501. The electromagnet 501 loses power and demagnetizes. The piston plate 502 moves down along the inside of the positioning tube 10 under the action of gravity, and then presses the air inside the positioning tube 10 into the strip-shaped airbag 401 through the air tube 402, causing the strip-shaped airbag 401 to expand and tighten the inner wall of the settlement ring 20 again, realizing the re-locking of the settlement ring 20. At this time, the staff can obtain the settlement amount of the ground by measuring the sliding distance of the settlement ring 20 along the outside of the positioning tube 10.

[0038] Please refer to Figure 1 and Figure 3 In one embodiment, the upper part of the piston plate 502 is connected to the inner top wall of the positioning tube 10 through an elastic member 503, and the elastic member 503 is used to provide elastic support for the piston plate 502.

[0039] When the electromagnet 501 is energized and then pushes the piston plate 502 upward through the permanent magnet, the piston plate 502 drives the elastic member 503 to be compressed. When the electromagnet 501 loses power and demagnetizes, the piston plate 502 can quickly move downward along the inside of the positioning tube 10 under its own gravity and the auxiliary push of the elastic member 503, and then reversely press the air into the strip-shaped airbag 401 to achieve the rapid locking of the settlement ring 20.

[0040] In one embodiment, the elastic member 503 can be a spring or a metal shrapnel, and there is no limitation here.

[0041] Please refer to Figure 3 , in one embodiment, a retaining ring 102 is further fixedly arranged on the inner wall of the positioning tube 10. The retaining ring 102 is located between the electromagnet 501 and the piston plate 502 to limit the piston plate 502, so that there is a space for the air pipe 402 to extend between the piston plate 502 and the electromagnet 501, so as to facilitate the piston plate 502 to smoothly pump air and compress air for the strip-shaped airbag 401 when moving along the inside of the positioning tube 10.

[0042] In one embodiment, scales are arranged on the outer wall of the positioning tube 10. Through the setting of the scales, it is convenient to quickly understand the sliding distance of the settlement ring 20 after the settlement ring 20 slides down along the outside of the positioning tube 10, so that the staff does not need to measure the sliding distance of the settlement ring 20 with the help of measuring tools, thereby improving the measurement effect of the ground settlement amount.

[0043] In the embodiment of the present invention, when monitoring ground settlement, the lower end of the positioning tube 10 can be inserted into the ground to be monitored so that the bottom of the settlement ring 20 contacts the ground. At this time, the locking assembly 40 locks the settlement ring 20 and the positioning tube 10 into one body to prevent the settlement ring 20 from pressing the ground under its own gravity, thereby causing the ground to sink; when the ground below the settlement ring 20 settles, the detection assembly 30 detects the ground settlement phenomenon. At this time, the unlocking assembly 50 releases the locked state of the settlement ring 20, and the settlement ring 20 slides down along the outside of the positioning tube 10 under its own gravity until the settlement ring 20 contacts the ground again, and the locking assembly 40 locks the settlement ring 20 again. At this time, the staff can measure the sliding distance of the settlement ring 20 along the outside of the positioning tube 10 to obtain the ground settlement amount. Compared with the prior art, when monitoring ground settlement, the interference of the self-gravity of the settlement ring 20 can be excluded, and at the same time, the settlement ring 20 can flexibly slide down along the outside of the positioning tube 10 after the ground settles, thereby improving the accuracy of the ground settlement amount measurement result and the sensitivity during the ground settlement monitoring process.

[0044] The above describes the preferred embodiments of the present invention in detail. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those of ordinary skill in the art.
