Description

Technical Field

[0001] This utility model relates to the field of settlement monitoring technology, specifically to an anti-bending device for a settlement meter probe sensor. Background Technology

[0002] A settlement probe sensor is a key device for measuring the stratified settlement of soil. It mainly achieves high-precision displacement monitoring through the principle of magnetic induction. Its core components include a magnetic probe, a sedimentation tube with a magnetic ring, and a signal processing system. When the probe moves along the sedimentation tube, the change in the magnetic field of the magnetic ring is sensed by the probe and converted into an electrical signal, which is then displayed as an audible and visual prompt or a digital output.

[0003] In the existing technology patent CN202265815U, the telescopic rod of the displacement sensor is fixedly connected to the settlement plate. When the settlement plate settles, the displacement sensor detects it and the wireless module sends a signal. Since the settlement plate is sleeved on the reference tube, in order to ensure the effective displacement of the settlement plate, the slot of the settlement plate sleeved on the reference tube is larger than the reference tube, so that there is a gap between the two. The settlement plate will move laterally within the gap. When the lateral displacement of the soil occurs, the telescopic rod of the displacement sensor is subjected to lateral force, which can easily cause the telescopic rod to deform or press against the inner wall of the displacement sensor, causing wear. After the telescopic rod deforms, it will affect the accuracy of the settlement measurement. To address this, we propose an anti-bending device for the probe-type sensor of the settlement meter. Utility Model Content

[0004] The purpose of this invention is to provide an anti-bending device for a sedimentation meter probe sensor, so as to solve the existing problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bend-resistant device for a sedimentation meter probe sensor, comprising a reference tube;

[0006] A tensioning assembly includes a bushing, one side of which is fixedly connected to the inner ring surface of a reference tube. A rotating shaft is rotatably connected inside the bushing via a bearing. A retaining ring is fixedly sleeved on the side surface of the rotating shaft. A retaining spring is movably sleeved on the side surface of the bushing. A second retaining post is fixedly connected to one side of the retaining ring. A first retaining post is fixedly connected to the inner ring surface of the reference tube. The two retaining feet of the retaining spring abut against the first and second retaining posts, respectively.

[0007] A wire-laying assembly includes a pull rope, one end of which is fixedly connected to the side surface of a rotating shaft and wrapped around the side surface of the rotating shaft. The other end of the pull rope is fixedly connected to a pull rod, one end of which passes through the top of a reference tube and is slidably connected thereto. The other end of the pull rod is fixedly connected to a settling plate, and the settling plate is slidably sleeved on the side surface of the reference tube.

[0008] The monitoring component includes a housing, one side of which is fixedly connected to the side surface of a reference tube. One end of a rotating shaft passes through the reference tube and extends to the inner wall of one side of the housing, where it is rotatably connected via a bearing. A permanent magnet is fixedly connected to the side surface of a section of the rotating shaft located inside the housing. A coil is fixedly sleeved on the inner ring surface of the housing.

[0009] Preferably, an anchor plate is fixedly connected to the bottom of the reference tube, and the reference tube and the anchor plate are pre-embedded at the monitoring point.

[0010] Preferably, the retaining ring provides a force in one direction of rotation of the shaft, and the force applied to the shaft by the retaining ring is used to wind up and tighten the pull rope.

[0011] Preferably, the tie rod moves downward as the settlement plate settles with the soil, and the downward movement of the tie rod is used to pull the rope to reverse the rotation shaft.

[0012] Preferably, the permanent magnets generate an induced current in the coil as the shaft rotates. There are multiple permanent magnets arranged in a circular array around the central axis of the shaft. The arrangement of the wire-laying assembly and the monitoring assembly ensures that lateral displacement of the soil layer will not affect either assembly. The reference tube protects the wire-laying assembly, and the pull rope provides a flexible connection to the monitoring assembly. Even if the pull rod and settlement plate deflect due to lateral forces, the flexible connection of the pull rope will not trigger the monitoring assembly, thus preventing measurement errors caused by deformation of the detection area and avoiding structural wear and misjudgment of the lateral displacement caused by soil lateral displacement. The tensioning assembly tightens the pull rope, ensuring that the pull rod effectively pulls the rope to rotate the shaft during settlement, preventing the pull rod from failing to effectively drive the shaft when the rope is loose. The spring clip tightening the pull rope improves the accuracy of settlement displacement measurement.

[0013] Preferably, there are two retaining rings, and the two retaining rings are used to limit the winding position of the pull rope.

[0014] Preferably, the settlement plate is buried in the monitoring soil and slides up and down along the longitudinal direction of the reference pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This anti-bending device for a sedimentation meter probe sensor...

[0016] The setup of the layout and monitoring components ensures that lateral displacement of the soil layer will not affect either component. The reference tube protects the layout component, while the pull rope provides a flexible connection with the monitoring component. Even if the tie rod and settlement plate deflect due to lateral forces, the flexible connection of the pull rope will not trigger the monitoring component, thus preventing measurement errors caused by deformation of the detection part. It also avoids structural wear caused by lateral displacement of the soil and misjudgment of the amount of lateral displacement.

[0017] The tensioning assembly tightens the rope, ensuring that the pull rod effectively pulls the rope to rotate the shaft during settlement. This prevents the pull rod from failing to effectively drive the shaft when the rope becomes loose and the pull rod moves downward. The tensioning effect of the retaining spring on the rope improves the accuracy of settlement displacement measurement. Attached Figure Description

[0025] 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.

[0026] This utility model embodiment provides an anti-bending device for a sedimentation meter probe sensor, such as... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, it includes reference tube 1;

[0027] The tensioning assembly 2 includes a bushing 201. One side of the bushing 201 is fixedly connected to the inner ring surface of the reference tube 1. The inside of the bushing 201 is rotatably connected to a rotating shaft 204 via a bearing. A retaining ring 205 is fixedly sleeved on the side surface of the rotating shaft 204. A snap ring 202 is movably sleeved on the side surface of the bushing 201. A second stop post 206 is fixedly connected to one side of the retaining ring 205. A first stop post 203 is fixedly connected to the inner ring surface of the reference tube 1. The two locking feet of the snap ring 202 abut against the first stop post 203 and the second stop post 206, respectively.

[0028] The wire laying assembly 3 includes a pull rope 301. One end of the pull rope 301 is fixedly connected to the side surface of the rotating shaft 204 and the pull rope 301 is wrapped around the side surface of the rotating shaft 204. The other end of the pull rope 301 is fixedly connected to a pull rod 302. One end of the pull rod 302 passes through the top of the reference tube 1 and is slidably connected to it. The other end of the pull rod 302 is fixedly connected to a settling plate 303 and the settling plate 303 is slidably sleeved on the side surface of the reference tube 1.

[0029] Monitoring component 4 includes a housing 401, one side of which is fixedly connected to the side surface of the reference tube 1. One end of a rotating shaft 204 passes through the reference tube 1 and extends to the inner wall of one side of the housing 401, where it is rotatably connected via a bearing. A permanent magnet 402 is fixedly connected to the side surface of a section of the rotating shaft 204 located inside the housing 401. A coil 403 is fixedly sleeved on the inner ring surface of the housing 401. In use, the reference tube 1 and the anchor plate 5 are first pre-embedded in the soil at the reference point, and the settlement plate 303 is set at a suitable soil height. When settlement occurs, the settlement plate 303 moves down along with the surrounding soil, the pull rod 302 moves downward and pulls the pull rope 301, so that the force overcomes the force of the snap ring 202 and makes the rotating shaft 204 rotate. The rotating shaft 204 located in the housing 401 drives the permanent magnet 402 to rotate, so that the permanent magnet 402 and the coil 403 rotate relative to each other, thereby causing the magnetic field to cut the coil 403 and generate an induced current. The staff connects the coil 403 to the wireless communication module through a wired connection and sends the electrical signal generated by the coil 403 to the receiving end to complete the monitoring.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the bottom of the reference tube 1 is fixedly connected to the anchor plate 5, and the reference tube 1 and the anchor plate 5 are pre-embedded at the monitoring point.

[0031] like Figure 1 , Figure 3 and Figure 5 As shown, the snap ring 202 provides a force in the unidirectional rotation direction of the shaft 204, and the force applied to the shaft 204 by the snap ring 202 is used to wind up and tighten the pull rope 301.

[0032] like Figure 3 , Figure 4 and Figure 5 As shown, the tie rod 302 moves downward as the settlement plate 303 settles in the soil. The downward movement of the tie rod 302 is used to pull the rope 301 to reverse the rotation shaft 204.

[0033] like Figure 3 , Figure 4 and Figure 5As shown, the permanent magnet 402 rotates with the shaft 204, inducing a current in the coil 403. There are multiple permanent magnets 402, arranged in a circular array around the central axis of the shaft 204. The arrangement of the wire laying assembly 3 and the monitoring assembly 4 ensures that lateral displacement of the soil layer will not affect either component. The reference tube 1 protects the wire laying assembly 3, and the pull rope 301 provides a flexible connection to the monitoring assembly 4. Even when the pull rod 302 and the settlement plate 303 are subjected to lateral forces and deflect, the flexible connection of the pull rope 301 ensures that... The monitoring component 4 will not be triggered, thus preventing measurement errors caused by deformation of the detection part, and avoiding structural wear caused by lateral displacement of the soil and misjudgment of the lateral displacement. By tightening the component 2, the pull rope 301 is tightened, thus ensuring that when settlement occurs, the pull rod 302 effectively pulls the pull rope 301 to rotate the shaft 204, thus avoiding the inability to effectively drive the shaft 204 to rotate after the pull rod 302 moves down when the pull rope 301 is loose. The tightening effect of the retaining spring 202 on the pull rope 301 can improve the measurement accuracy of settlement displacement.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, there are two retaining rings 205, and the two retaining rings 205 are used to limit the winding position of the pull rope 301.

[0035] like Figure 1 , Figure 3 and Figure 5 As shown, the settlement plate 303 is buried in the monitored soil and slides up and down along the longitudinal direction of the reference pipe 1.

[0036] Working principle: When in use, the reference pipe 1 and anchor plate 5 are first pre-embedded in the soil at the reference point. The settlement plate 303 is set at a suitable soil height. When settlement occurs, the settlement plate 303 moves down with the surrounding soil. The pull rod 302 moves down and pulls the pull rope 301, so that the force overcomes the force of the snap ring 202 and makes the rotating shaft 204 rotate. The rotating shaft 204 located in the housing 401 drives the permanent magnet 402 to rotate, so that the permanent magnet 402 and the coil 403 rotate relative to each other. In turn, the magnetic field cuts the coil 403 to generate an induced current. The operator connects the coil 403 to the wireless communication module through a wired connection and sends the electrical signal generated by the coil 403 to the receiving end to complete the monitoring.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
