[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the specification of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] See Figures 1-4 A preferred embodiment of the present invention provides a foundation settlement detection device, comprising: a support frame 1 and a detector 3;

[0029] The support frame 1 includes a mounting base 101 (the mounting base 101 can be equipped with a level detector 3 for users to check whether the mounting base 101 is level) and movable support rods 2; multiple movable support rods 2 are provided, and the multiple movable support rods 2 are arranged at intervals around the mounting base 101 to jointly form a protective space 102; each of the movable support rods 2 is hinged to the mounting base 101 so that it can swing relative to the mounting base 101 in a vertical plane; it can be understood that by adjusting the angle between the movable support rod 2 and the mounting base 101, the volume of the protective space 102 can change with the angle. With this arrangement, each of the movable support rods 2 can be fixed in a stable area, thereby preventing the mounting base 101 from settling along with the foundation settlement, thereby reducing the measurement error of the equipment.

[0030] The detector 3 includes a settlement measuring ruler 4 and a detector 301. The settlement measuring ruler 4 has a sliding section 401 and a grounding end 402. The sliding section 401 extends along the direction of gravity and is slidably inserted into the mounting base 101. The sliding section 401 has a measuring scale section 403, which is used to display the difference in ground settlement before and after settlement. The grounding end 402 is used to contact the ground surface to be measured. The detector 301 is installed on the mounting base 101, with its detection end facing the measuring scale section 403. Obviously, since the mounting base 101 cannot settle with the ground settlement, it can serve as a comparison index for the settlement measuring ruler 4. Therefore, after the detector 301 is installed on the mounting base 101, it can stably measure the changes in the measuring scale section 403, thereby improving the accuracy of the measurement results.

[0031] In use, the user first needs to place the support frame 1 in the area to be measured; then the user needs to adjust the angle between each of the movable support rods 2 and the mounting base 101 so that the movable support is supported on a stable site, and use the level detector 3 installed on the mounting base 101 to check whether the mounting base 101 is level; after the support frame 1 is stable, the grounding end 402 of the settlement measuring ruler 4 is inserted into the ground surface to start the measurement; when the foundation settles, the measuring scale segment 403 changes with the foundation settlement, and the detector 301 detects and records the change.

[0032] The support frame 1 includes a mounting base 101 and movable support rods 2. Multiple movable support rods 2 are provided, spaced apart around the mounting base 101 to form a protective space 102. Each movable support rod 2 is hinged to the mounting base 101, allowing it to swing relative to the mounting base 101 in a vertical plane. It is understood that by adjusting the angle between the movable support rod 2 and the mounting base 101, the volume of the protective space 102 can change accordingly. This configuration allows each movable support rod 2 to be fixed in a stable area, thereby preventing the mounting base 101 from settling along with the foundation and reducing measurement errors in the equipment.

[0033] The detector 3 includes a settlement measuring ruler 4 and a detector 301. The settlement measuring ruler 4 has a sliding section 401 and a grounding end 402. The sliding section 401 extends along the direction of gravity and is slidably inserted into the mounting base 101. The sliding section 401 has a measuring scale section 403, which is used to display the difference before and after foundation settlement. The grounding end 402 is used to contact the ground surface to be measured. The detector 301 is installed on the mounting base 101, and the detection end of the detector 301 is set towards the measuring scale section 403. Obviously, since the mounting base 101 cannot settle with the foundation settlement, it can serve as a comparison index for the settlement measuring ruler 4. Therefore, after the detector 301 is installed on the mounting base 101, it can stably measure the changes in the measuring scale section 403, thereby improving the accuracy of the measurement results.

[0034] See Figure 2 Preferably, the movable support rod 2 includes a fixed rod 201 and a sliding rod 202; the top end of the fixed rod 201 is hinged to the mounting base 101 to support the mounting base 101; one of the sliding rod 202 and the fixed rod 201 is provided with a rod guide groove, and the other is provided with a guide block; the rod guide groove extends along the extension direction of the sliding rod 202, and the guide block slides in cooperation with the rod guide groove; the bottom of the sliding rod 202 is used to support the ground; obviously, with this configuration, the movable support rod 2 can be extended to achieve a wider installation range, so that the user can place the bottom of the sliding rod 202 against a more distant stable area.

[0035] See Figure 3Preferably, the movable support rod 2 is provided with a slidable locking member 103, and the slidable locking member 103 is provided with a rod receiving space 105. The sliding rod 202 and the fixed rod 201 are arranged in a cooperating state within the rod receiving space 105, so that the slidable locking member 103 can slide along the direction of extension of the sliding rod 202. The slidable locking member 103 is used to lock the sliding rod 202 to the fixed rod 201. Obviously, the slidable locking member 103 can protect and guide the sliding rod 202 and the fixed rod 201, preventing the sliding rod 202 and the fixed rod 201 from separating from each other and causing damage to the movable support rod 2. In addition, it can also brake the relative sliding between the two, thereby making the support frame 1 more stable.

[0036] See Figure 1 Preferably, the slidable locking member 103 is provided with threads, and the threads are connected to a threaded knob 104. The threaded knob 104 is used to penetrate into the rod receiving space 105 so that the inner wall of the slidable locking member 103 is pressed against the outer wall of the sliding rod 202 and the fixed rod 201. It can be understood that this setting can facilitate the user to lock or unlock the slidable locking member 103, thereby improving the usability of the support frame 1.

[0037] See Figure 3 Preferably, the support frame 1 further includes an auxiliary positioning component 5, which is housed within the protective space 102 and connected to each of the slidable locking members 103 to move up and down in conjunction with the slidable locking members 103; the auxiliary positioning component 5 is used to limit the swaying of the settlement measuring ruler 4; this arrangement can prevent the settlement measuring ruler 4 from swaying after moving away from the mounting base 101, thus avoiding errors in the measurement results.

[0038] See Figure 4 Preferably, the mounting base 101 has a receiving channel 106 extending along the direction of gravity; the auxiliary positioning component 5 includes a positioning ring 501 and a linkage rod 502; the positioning ring 501 is coaxially arranged with the receiving channel 106; multiple linkage rods 502 are provided, and the multiple linkage rods 502 are distributed axially around the positioning ring 501 at intervals, with each end of the linkage rod 502 connected to the positioning ring 501 and one of the sliding locking members 103 respectively; the settlement measuring ruler 4 is slidably inserted into the receiving channel 106 and the positioning ring 501 along the direction of gravity; it can be understood that the lower middle section of the settlement measuring ruler 4 is subject to secondary limiting by the positioning ring 501 to avoid excessive swinging of the settlement measuring ruler 4, thereby improving the accuracy of the measurement results.

[0039] See Figure 3 Preferably, the two ends of the linkage rod 502 are respectively hinged to the positioning ring 501 and the slidable locking member 103; this arrangement can prevent the support frame 1 from being restricted from swinging by the positioning ring 501.

[0040] See Figure 3 Preferably, the settlement measuring ruler 4 is provided with a guide groove 404, which extends along the length of the settlement measuring ruler 4 and is recessed inward from the outer wall of the settlement measuring ruler 4; the inner ring wall of the receiving channel 106 is provided with an avoidance groove 107, which is recessed outward from the inner ring wall of the receiving channel 106; a guide wheel 108 is pivotally connected in the avoidance groove 107, and a portion of the guide wheel 108 is exposed in the guide groove 404 and abuts against the bottom wall of the guide groove 404; the inner ring wall of the positioning ring 501 is provided with a guide protrusion 503, which slides in cooperation with the guide groove 404; it can be understood that with this configuration, the raising and lowering of the settlement measuring ruler 4 is smoother, avoiding jamming that could cause measurement errors.

[0041] See Figure 4 Preferably, the detector 3 further includes a sensitivity adjustment component 6, which is mounted on the mounting base 101; the sensitivity adjustment component includes a fixed base 601, a threaded rod 602, an adjustment knob 603, and a damping stop rod 604; the fixed base 601 is disposed on the mounting base 101; the threaded rod 602 has a threaded portion and a restricted rotation portion, the threaded portion passes through the fixed base 601, and the restricted rotation portion is pivotally connected to the fixed base 601; the adjustment knob 603 is disposed on the restricted rotation portion; the damping stop rod 604... The damping stop rod 604 is threadedly connected to the threaded portion, allowing the damping stop rod 604 to approach or move away from the outer wall of the settlement measuring ruler 4. Clearly, when the damping stop rod 604 approaches the outer wall of the settlement measuring ruler 4, the raising and lowering of the settlement measuring ruler 4 is restricted, allowing the user to move the foundation settlement detection device. When the damping stop rod 604 moves away from the settlement measuring ruler 4, the damping stop rod 604 releases its contact with the settlement measuring ruler 4, thereby improving the sensitivity of the settlement measuring ruler 4 to foundation settlement.

[0042] See Figure 4Preferably, the outer wall of the settlement measuring ruler 4 is provided with a straight groove 405, which is recessed inward from the outer wall of the settlement measuring ruler 4 and extends along the length of the settlement measuring ruler 4; the damping stop rod 604 is provided with a braking protrusion, which is slidably nested in the straight groove 405 so that it can be driven by the threaded rod 602 to approach or move away from the bottom wall of the straight groove 405; the straight groove 405 is used to guide the braking protrusion to avoid the braking effect from being lost due to the misalignment of the landing point of the braking protrusion caused by the fit tolerance.
