Description

Technical Field

[0001] This utility model relates to the field of settlement monitoring technology, and in particular to a hook-on surface settlement monitoring device. Background Technology

[0002] Foundation settlement is caused by the transfer of building loads to the foundation soil, resulting in soil deformation and settlement. When designing pile foundations, it is necessary to fully consider the building loads and the mechanical properties of the foundation soil. By selecting reasonable parameters such as pile diameter, pile length, and pile spacing, the settlement of the pile foundation can be reduced. Foundation settlement is a dangerous signal, so it is necessary to detect surface settlement.

[0003] A search revealed that Chinese patent application CN119063697A discloses a ground subsidence monitoring system. This system mainly converts the linear displacement distance of a subsidence ring into the rotation of a rotating mechanism, which amplifies the minute linear displacement distance. The rotation angle of the rotating mechanism is then detected to accurately determine the minute linear displacement distance of the subsidence ring, thereby enabling precise monitoring of the minute amount of ground subsidence.

[0004] Compared with existing technologies in related fields, it can be seen that when existing detectors are used for testing, the placed tube drives the hook ring directly into the detection hole. Relying on the hook ring to adhere to the soil, it is easy for slight settlement detection errors to occur due to relative displacement, which affects the quality of the test. Utility Model Content

[0005] The purpose of this invention is to provide a hanging-type surface subsidence monitor in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions: A hanging-type surface settlement monitor includes a submerged tube, which is fixedly installed at the center of a limiting seat. A support unit is fixedly installed on the limiting seat. Threaded pipes and threaded sleeves are respectively provided at both ends of the submerged tube. A detection unit is slidably installed on the submerged tube. A lower plug is installed on the threaded pipe through threaded engagement, and an upper plug is installed on the threaded sleeve through threaded engagement. The detection unit includes a chute, a mounting ring, a guide rail, and a sensing mechanism. The chute is arranged on the immersed tube, and a sliding seat is slidably installed inside the chute. The sliding seat is fixedly connected to a fixing component, a mounting base, and a mounting ring. The mounting ring is slidably sleeved on the outside of the immersed tube. An installation cavity is provided inside the mounting ring, and a drive mechanism is fixedly installed inside the installation cavity. The drive mechanism is fixedly connected to a rotating shaft, which is rotatably arranged on the mounting ring. An arc plate is fixedly installed on the rotating shaft. The mounting base and the guide rail are located inside the immersed tube. A second electromagnetic mechanism is fixedly installed on the mounting base. The second electromagnetic mechanism is magnetically connected to the housing of the sensing mechanism. The sensing mechanism is slidably installed inside the mounting base. The guide rail is fixedly connected to the immersed tube, and the guide rail and the contact of the sensing mechanism are slidably connected.

[0007] Furthermore, the fixing component includes a magnetic plate and a first electromagnetic mechanism. The magnetic plate is fixedly mounted on the slide, and the first electromagnetic mechanism is fixedly mounted inside the upper end of the slide groove. The first electromagnetic mechanism is magnetically connected to the magnetic plate.

[0008] Furthermore, a protective sleeve and a protective plate are fixedly installed on the slide. The protective sleeve is slidably connected to the outer surface of the submerged tube, and the protective plate is slidably connected to the inner wall of the submerged tube.

[0009] Furthermore, guide grooves are provided on both sides of the protective plate, and a ball bearing mechanism is rotatably installed in the guide grooves. The ball bearing mechanism is slidably connected to the guide rail.

[0010] Furthermore, the mounting base is provided with a positioning groove, and the housing of the sensing mechanism is provided with a positioning plate, which is slidably installed in the positioning groove.

[0012] Furthermore, the lower surface of the support base is fixedly arranged with anti-slip teeth, and the upper surface of the support base is fixedly installed with a placement groove.

[0013] The advantages compared to existing technologies are as follows: 1. Different submerged tubes are connected by threaded pipes and threaded sleeves to facilitate site testing needs at different depths, thus expanding the applicability. The ball bearing mechanism improves smooth sliding and reduces frictional resistance. The arc plate increases the contact area between the hanging ring and the soil, allowing the hanging ring to move synchronously with the settling soil, effectively avoiding detection lag and errors caused by relative sliding between the hanging ring and the soil. It can accurately track minute settlements, ensuring the quality of testing and reducing deviations.

[0014] 2. The upper plug, lower plug, protective sleeve, and protective plate prevent dust, mud, and other impurities from entering the immersed tube, providing initial protection for the sensing mechanism and ensuring normal detection efficiency.

[0018] like Figures 1-8As shown, a hook-on type surface settlement monitor includes a submerged tube 1, which is fixedly installed at the center of a limiting seat 2. A support unit is fixedly installed on the limiting seat 2. Threaded pipes 5 and threaded sleeves 6 are respectively provided at both ends of the submerged tube 1. A detection unit is slidably installed on the submerged tube 1. A lower plug 7 is installed on the threaded pipe 5 through threaded engagement, and an upper plug 8 is installed on the threaded sleeve 6 through threaded engagement. Detection holes are drilled in the ground. Different submerged tubes 1 are connected through the threaded pipes 5 and threaded sleeves 6 according to the drilling depth, facilitating the detection needs of sites at different depths. The lower plug 7 is used to detect the submersion. The bottom end of pipe 1 is sealed, and the top end of pipe 1 is sealed by upper plug 8 to prevent external dust and other impurities from entering pipe 1 during the testing process, thus ensuring the normal testing effect of the testing unit. Pipe 1 and testing unit are placed in the testing hole. Pipe 1 is supported by support unit and limit seat 2 to prevent pipe 1 from shifting and affecting the accuracy of the testing results. By connecting pipes 1 to each other, testing unit can be placed at different depths in the borehole, improving the convenience of placement and reducing the workload during installation. The testing unit is used to detect the settlement of soil at different depths. like Figure 1 , Figure 2 , Figures 5-8As shown, the detection unit includes a slide 301, a hook ring 302, a guide rail 315, and a sensing mechanism 314. The slide 301 is arranged on the immersed tube 1. A slide seat 307 is slidably installed in the slide 301. The slide seat 307 is fixedly connected to a fixing component, a mounting base 312, and a hook ring 302. The hook ring 302 is slidably sleeved on the outside of the immersed tube 1. An installation cavity 303 is provided in the hook ring 302. A drive mechanism 304 is fixedly installed in the installation cavity 303. A rotating shaft 305 is fixedly connected to the drive mechanism 304. The rotating shaft 305 is rotatably arranged on the hook ring 302. An arc plate 306 is fixedly installed on the rotating shaft 305. The mounting base 312 and the guide rail 315 are located inside the immersed tube 1. A second electromagnetic mechanism 313 is fixedly installed on the mounting base 312. The magnetic mechanism 313 is magnetically connected to the housing of the sensing mechanism 314. The sensing mechanism 314 is slidably mounted in the mounting base 312. The guide rail 315 is fixedly connected to the submerged tube 1, and the guide rail 315 and the contact of the sensing mechanism 314 are slidably connected. The second electromagnetic mechanism 313, the drive mechanism 304, and the sensing mechanism 314 operate using existing technology. When the submerged tube 1 is installed into the detection hole, the sliding block 307 is fixed to the upper end of the slide groove 301 by the fixing assembly, so that the hanging ring 302 is in the initial position. The submerged tube 1 drives the hanging ring 302 into the detection hole on the ground. After the submerged tube 1 and the hanging ring 302 are installed in place, the drive mechanism 304 drives the arc plate 306 to rotate through the rotating shaft 305, so that the arc plate 306 expands and enters the side wall of the borehole. In the soil, the arc plate 306 increases the contact area with the soil, allowing the hook ring 302 to better receive the force during settlement. When soil settlement occurs, it can better follow the settling soil and move synchronously, effectively avoiding detection lag and errors caused by relative sliding between the hook ring 302 and the soil. This enables precise tracking of minute settlements, ensuring detection quality and reducing deviations. The fixing components are released from the sliding base 307. When soil settlement occurs, the settling soil causes the arc plate 306 to settle. The arc plate 306 moves the hook ring 302 via the rotating shaft 305. The hook ring 302 moves the mounting base 312 via the sliding base 307. The mounting base 312 moves the sensing mechanism 314 via the second electromagnetic mechanism 313. The movement of the sensor 314 along the guide rail 315 allows the contact to move, thus detecting soil settlement and improving the quality of soil settlement detection. If the sensor 314 is damaged during detection, the upper plug 8 at the top of the sinking tube 1 is removed, and the material-collecting rod is placed inside the sinking tube 1. This allows the material-collecting rod to move to the damaged sensor 314, releasing the attraction and fixation of the second electromagnetic mechanism 313 to the sensor 314, facilitating its quick removal. The sensor 314 is then placed back into the mounting base 312 using the material-collecting rod, and the second electromagnetic mechanism 313 re-attaches and fixes it, eliminating the need for complete excavation and replacement.This effectively improves the convenience and efficiency of replacing the 314 sensor mechanism, ensuring testing quality.

[0019] like Figure 8 As shown, the fixing assembly includes a magnetic plate 310 and a first electromagnetic mechanism 311. The magnetic plate 310 is fixedly installed on the slide 307, and the first electromagnetic mechanism 311 is fixedly installed inside the upper end of the slide groove 301. The first electromagnetic mechanism 311 is magnetically connected to the magnetic plate 310. The magnetic plate 310 and the first electromagnetic mechanism 311 operate using existing technology. When the immersed tube 1 is placed into the detection hole, the first electromagnetic mechanism 311 attracts and fixes the magnetic plate 310, so that the slide 307 is located at the upper end of the slide groove 301. This prevents the slide 307 from moving along the slide groove 301 during the placement of the immersed tube 1, ensuring that the slide 307 has sufficient sliding space in the slide groove 301 after the immersed tube 1 is installed in place, thus ensuring effective detection. After the immersed tube 1 is installed in place, the first electromagnetic mechanism 311 is de-energized to release the attraction and fixation of the magnetic plate 310, ensuring that the settled soil can drive the slide 307 to move normally in the slide groove 301, thus ensuring the quality of detection.

[0020] like Figure 1 , Figure 2 , Figures 5-8 As shown, a protective sleeve 308 and a protective plate 309 are fixedly installed on the slide 307. The protective sleeve 308 is slidably connected to the outer surface of the immersed tube 1, and the protective plate 309 is slidably connected to the inner wall of the immersed tube 1. The protective sleeve 308 and the protective plate 309 operate using existing technology. The slide 307 drives the protective sleeve 308 and the protective plate 309 to move along the immersed tube 1. The protective sleeve 308 and the protective plate 309 shield and protect the slide groove 301, preventing mud in the detection hole from entering the immersed tube 1, reducing the impact of mud and other impurities on the sensing mechanism 314, and ensuring the detection quality of the sensing mechanism 314.

[0021] like Figure 6 As shown, guide grooves are provided on both sides of the protective plate 309, and a ball bearing mechanism 316 is rotatably installed in the guide grooves. The ball bearing mechanism 316 is slidably connected to the guide rail 315. The ball bearing mechanism 316 operates using existing technology. By reducing the friction between the guide rail 315 and the protective plate 309, the protective plate 309 can slide better along the guide rail 315, reducing the resistance of friction to the movement of the protective plate 309, and can better follow the soil settlement, thereby improving the real-time performance of micro-settlement detection and ensuring the accuracy of the detection results.

[0022] like Figure 6As shown, the mounting base 312 is provided with a positioning groove, and the housing of the sensing mechanism 314 is provided with a positioning plate. The positioning plate is slidably installed in the positioning groove. The positioning plate and the positioning groove enable the sensing mechanism 314 to be positioned and installed on the mounting base 312, which effectively improves the convenience of installing the sensing mechanism 314. At the same time, it can prevent the sensing mechanism 314 from being misaligned during installation, ensuring that the sensing mechanism 314 is installed in place and guaranteeing the detection quality of the sensing mechanism 314.

[0023] like Figure 1 , Figure 4 , Figure 7 As shown, the support unit includes a telescopic adjustment rod 401, which is arranged in a circular array on the limiting seat 2. The lower end of the telescopic adjustment rod 401 is fixedly mounted with a support seat 402 by bolts. The telescopic adjustment rod 401 operates using existing technology. The support seat 402 improves the stability of the telescopic adjustment rod 401 during support. The support seat 402 and the telescopic adjustment rod 401 enable the limiting seat 2 to stably support the immersed tube 1, effectively preventing the immersed tube 1 from shifting during the inspection process and ensuring that the immersed tube 1 remains vertical, thus guaranteeing the accuracy of the inspection structure. By adjusting the support length of the telescopic adjustment rod 401, it is convenient to ensure that the limiting seat 2 effectively supports the immersed tube 1 when measuring under different ground conditions.

[0024] like Figure 4 As shown, anti-slip teeth 404 are fixedly arranged on the lower surface of the support base 402, and a placement groove 403 is fixedly installed on the upper surface of the support base 402. The anti-slip teeth 404 improve the anti-slip properties of the support base 402, so that the support base 402 is stably supported on the ground. At the same time, by placing a weight in the placement groove 403 to increase the weight of the support base 402, and in conjunction with the anti-slip teeth 404, the stability of the support base 402 is improved, preventing the support base 402 from moving. This provides stable support for the limiting seat 2 and the sinker 1, and avoids slippage during the support process from affecting the quality of the test.

[0025] Working principle: such as Figure 1 , Figure 3 , Figure 7 , Figure 8 As shown, a test hole is drilled in the ground. According to the depth of the drill hole, different sinker tubes 1 are connected by threaded pipe 5 and threaded sleeve 6. The bottom end of the sinker tube 1 is sealed by the lower plug 7 and the top end of the sinker tube 1 is sealed by the upper plug 8. The magnetic plate 310 is attracted and fixed by the first electromagnetic mechanism 311, so that the slide 307 is located at the upper end of the slide groove 301. The sinker tube 1 and the hanging ring 302 are placed into the test hole. like Figure 1 , Figure 2 , Figure 5 , Figure 8As shown, after the immersed tube 1 and the hanging ring 302 are placed in place, the drive mechanism 304 drives the arc plate 306 to rotate through the rotating shaft 305, so that the arc plate 306 expands and enters the soil on the side wall of the borehole. The arc plate 306 increases the contact area with the soil. The first electromagnetic mechanism 311 is de-energized, thereby releasing the adsorption and fixation of the magnetic plate 310. like Figure 1 , Figure 4 , Figure 7 As shown, the support length of the telescopic adjustment rod 401 is adjusted so that the limit seat 2 can stably support the sink tube 1 through the support seat 402 and the telescopic adjustment rod 401. The anti-slip property of the support seat 402 is improved by the anti-slip teeth 404. The weight of the support seat 402 is increased by placing a weight in the placement groove 403, and the stability of the support seat 402 is improved in conjunction with the anti-slip teeth 404 to prevent the support seat 402 from moving. like Figure 1 , Figure 2 , Figures 5-8 As shown, when soil settlement occurs, the settled soil causes the arc plate 306 to settle. The arc plate 306 drives the hanging ring 302 to move via the rotating shaft 305. The hanging ring 302 drives the mounting base 312 to move via the sliding seat 307. The mounting base 312 drives the sensing mechanism 314 to move via the second electromagnetic mechanism 313, so that the contact of the sensing mechanism 314 moves along the guide rail 315. Based on the moving distance of the contact of the sensing mechanism 314 on the guide rail 315, the soil settlement is detected, effectively improving the quality of soil settlement detection. like Figure 1 , Figure 2 , Figure 6 , Figure 8 As shown, during the settling process of the hanging ring 302, the sliding groove 301 is shielded and protected by the protective sleeve 308 and the protective plate 309 to prevent the mud in the detection hole from entering the sinking tube 1 and reduce the impact of mud and other impurities on the sensing mechanism 314. At the same time, the ball bearing mechanism 316 reduces the friction between the guide rail 315 and the protective plate 309, making it easier for the protective plate 309 to slide along the guide rail 315 and settle better with the soil, thus ensuring the accuracy of the detection results of the sensing mechanism 314. like Figure 6 , Figure 8As shown, when the sensing mechanism 314 is damaged during the testing process, the upper plug 8 at the upper end of the sink tube 1 is removed, and the material picker is placed into the sink tube 1, so that the material picker moves to the damaged sensing mechanism 314, releasing the adsorption and fixation of the sensing mechanism 314 by the second electromagnetic mechanism 313, making it easier to quickly remove the sensing mechanism 314. The sensing mechanism 314 is then placed back into the position of the mounting base 312 by the material picker, and the sensing mechanism 314 is adsorbed and fixed again by the second electromagnetic mechanism 313. The positioning plate and positioning groove ensure that the sensing mechanism 314 is positioned and installed on the mounting base 312, preventing the sensing mechanism 314 from being tilted during installation, ensuring that the sensing mechanism 314 is installed in place, and guaranteeing the quality of the test.
