[0002] Ground subsidence monitoring is a disaster prevention and mitigation method that uses a multi-dimensional technical system to continuously observe the vertical displacement of the earth's surface, aiming to provide data support for geological disaster risk assessment and prevention and control decisions.

[0003] Existing ground settlement monitoring devices are key tools for measuring and monitoring the settlement of land or structures. The core principle is to acquire ground or building settlement data in real time through sensors, measuring instruments and data processing systems to ensure engineering safety and land stability. This includes lidar scanning technology, which can quickly acquire the three-dimensional shape of the ground surface. Combined with other methods, it can achieve high-precision settlement monitoring and is suitable for monitoring complex terrain or large structures.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] Please see Figure 1 - Figure 5This utility model provides a ground settlement monitoring device, including a placement turntable 1 and a supporting base 2; a T-shaped clamp 3 is rotatably connected to the top of the supporting base 2, and the top of the T-shaped clamp 3 is fixedly connected to the bottom of the placement turntable 1; a rotating shaft 4 is rotatably connected to the center of the placement turntable 1, and a half gear 5 is fixedly connected to the top of the rotating shaft 4; inner and outer double toothed plates 6 are slidably connected to the top of the placement turntable 1, and the surface of the half gear 5 meshes with the inner side of the inner and outer double toothed plates 6; a rotating gear 7 is rotatably connected to the top of the placement turntable 1 and located on one side of the inner and outer double toothed plates 6, and the surface of the rotating gear 7 meshes with the outer side of the inner and outer double toothed plates 6; a supporting column 8 is fixedly connected to the center of the top of the rotating gear 7, and a laser radar scanner 9 is fixedly connected to the top of the supporting column 8; during operation, the top of the placement turntable 1 rotates to support the half gear 5 and slides to support the inner and outer double toothed plates 6. When the rotating shaft 4 rotates, it drives the half gear 5 to rotate. Since the half gear 5 meshes with the inner side of the inner and outer double toothed plates 6, the rotation of the half gear 5 causes the inner and outer double toothed plates 6 to make linear reciprocating motion on the placement turntable 1. Meanwhile, the outer side of the inner and outer double toothed plates 6 meshes with the rotating gear 7. The reciprocating motion of the inner and outer double toothed plates 6 drives the rotation of the rotating gear 7. The rotation of the rotating gear 7 drives the lidar scanner 9 to scan at a certain angle through the support column 8. The lidar scanner 9 emits a laser beam to scan the ground, obtain the three-dimensional shape data of the ground, and transmits this data to the data processing system. The data processing system processes and analyzes the received data to determine the ground subsidence. This design enables the lidar scanner 9 to perform large-area scanning and monitoring on the horizontal plane, thereby effectively expanding the monitoring area and improving monitoring efficiency.

[0019] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a T-shaped rail 10 is provided on the top of the support base 2, and the bottom of the T-shaped cylinder 3 is rotatably connected to the inner wall of the T-shaped rail 10. A motor cylinder 11 is fixedly connected to the bottom of the support base 2, and a motor 12 is fixedly connected inside the motor cylinder 11. One end of the rotating shaft 4 passes through the turntable 1, the T-shaped cylinder 3, and the support base 2 in sequence and extends to the bottom of the support base 2. The output shaft of the motor 12 is fixedly connected to the end of the rotating shaft 4 located at the bottom of the support base 2 through a coupling. During operation, the T-shaped rail 10 is provided on the top of the support base 2 to support the T-shaped cylinder 3 and limit its movement. At the same time, the motor cylinder 11 is fixed at the bottom of the support base 2, and the motor 12 is supported and installed by the motor cylinder 11. After the motor 12 starts working, it drives the rotating shaft 4 to start rotating through the output shaft, thereby providing power for the angle adjustment of the lidar scanner 9.

[0020] Furthermore, such as Figure 2 and Figure 3As shown, a limiting bracket 13 is fixedly connected to the top of the turntable 1. One side of the limiting bracket 13 extends through to the inner side of the inner and outer double toothed plates 6. There are two limiting brackets 13, and the two limiting brackets 13 are symmetrically arranged on the upper and lower sides of the inner and outer double toothed plates 6. A protective cover 14 is fixedly connected to the top of the turntable 1. A support column 8 passes through the protective cover 14 and extends to the top of the protective cover 14. The surface of the support column 8 is rotatably connected to the surface of the protective cover 14. A stabilizing gravity block 15 is fixedly connected to the bottom of the turntable 1 on the side away from the rotating gear 7. A rotating handle 16 is fixedly connected to the side of the turntable 1 closest to the stabilizing gravity block 15. During operation, a limiting bracket 13 is fixed to the top of the turntable 1. One side of the limiting bracket 13 extends to the inner side of the inner and outer double toothed plates 6, allowing for limiting the movement of the inner and outer double toothed plates 6. Additionally, a protective cover 14 is fixed to the top of the turntable 1, protecting the internal half gear 5, inner and outer double toothed plates 6, and rotating gear 7. During monitoring, a stabilizing gravity block 15 enhances the stability of the turntable 1, preventing it from shaking due to external interference and ensuring the accuracy of the monitoring data. When the monitoring angle needs to be adjusted, the operator can manually adjust the angle of the turntable 1 by turning the handle 16 to meet different monitoring requirements, further improving its adaptability.

[0021] Working Principle: Since the monitoring primarily targets a specific location, the monitoring area is limited. Accurate monitoring of larger areas is difficult, leading to issues with monitoring efficiency. First, a rotating support half-gear 5 is placed on top of the turntable 1, which in turn supports inner and outer double-toothed plates 6. When the rotating shaft 4 rotates, it drives the half-gear 5 to rotate. Because the half-gear 5 meshes with the inner sides of the inner and outer double-toothed plates 6, the rotation of the half-gear 5 causes the inner and outer double-toothed plates 6 to reciprocate linearly on the turntable 1. Meanwhile, the outer sides of the inner and outer double-toothed plates 6 mesh with a rotating gear 7, and the reciprocating motion of the inner and outer double-toothed plates 6 drives the rotation of the rotating gear 7. The rotation of the rotating gear 7, through the support column 8, drives the lidar scanner 9 to scan at a certain angle. The lidar scanner 9 emits a laser beam to scan the ground, acquiring three-dimensional morphological data of the ground and transmitting this data to the data processing system. The data processing system processes and analyzes the received data to determine the ground subsidence. This design allows the lidar scanner 9 to perform large-scale scanning monitoring on the horizontal plane, effectively expanding the monitoring area and improving monitoring efficiency. Meanwhile, a T-shaped rail 10 is provided on the top of the support base 2 to support the T-shaped clamping cylinder 3 and limit the T-shaped clamping cylinder 3. At the same time, a motor cylinder 11 is fixed at the bottom of the support base 2, and a motor 12 is installed on the support cylinder 11. After the motor 12 is working, it drives the rotating shaft 4 to start rotating through the output shaft, thereby providing power for the angle adjustment of the laser radar scanner 9. In addition, a limiting bracket 13 is fixed on the top of the turntable 1. One side of the limiting bracket 13 extends to the inner side of the inner and outer double toothed plates 6, and can limit the sliding of the inner and outer double toothed plates 6. In addition, a protective cover 14 is fixed on the top of the turntable 1, which protects the half gear 5, inner and outer double toothed plates 6 and rotating gear 7 inside. During the monitoring process, the stabilizing gravity block 15 enhances the stability of the turntable 1 and prevents the turntable 1 from shaking due to external interference, thus ensuring the accuracy of the monitoring data. When it is necessary to adjust the monitoring angle, the operator can manually adjust the angle of the turntable 1 by turning the handle 16 to meet different monitoring needs and further improve the adaptability of use.
