Description

Technical Field

[0001] The utility model belongs to the technical field of ground subsidence monitoring, and particularly relates to a ground subsidence monitoring leveling instrument. Background Art

[0002] The ground subsidence monitoring leveling instrument is an instrument specially used to accurately measure ground subsidence. It is based on the principle of leveling and can reliably monitor ground subsidence changes, providing key data for geological disaster prevention, urban planning, engineering construction, etc. When in use, it is necessary to ensure that the instrument is level, set observation points and benchmark points, and conduct periodic elevation measurements. The amount of settlement is determined by comparing observation results at different times. The instrument is highly precise, stable and easy to operate. It can monitor ground subsidence in real time, warn of geological disasters, and evaluate the impact of projects on subsidence. When using it, it is necessary to comply with regulations, ensure safety, and perform regular maintenance and calibration.

[0003] The Chinese patent with the publication number of "CN217818704U" discloses a leveling instrument for construction, which includes a protection box, the protection box is a box body with openings on both sides, and the inner side of the protection box is installed with a leveling device. The utility model is equipped with a protection box and an objective lens cover plate, and the leveling device can be protected under the action of the protection box, so that it can be protected when not in use, and the leveling device is prevented from being damaged. The objective lens cover plate can be unfolded to a horizontal state when in use under the action of an unfolding mechanism, and the objective lens plays a sunshade state, preventing the sun's rays from affecting the written structure, making the measurement data more accurate. Under the action of a locking mechanism, the eyepiece cover plate can be connected to the end of a connecting sleeve, so that the protection box forms a complete box body, and when in use, only the connecting sleeve needs to be pushed to expose the eyepiece of the leveling device, which does not affect the use of the eyepiece, and increases the practicality of the device.

[0004] Although the above-mentioned device can improve its detection convenience during use, in its specific application process, since the measuring instrument is located as a whole inside the protective box, it is obviously inconvenient to flexibly adjust its use height and direction during the detection process. In practical use, it is necessary to ensure that the instrument is in a horizontal state, and the above-mentioned device often needs to be manually adjusted in angle during use, which is extremely cumbersome and inconvenient. It can be seen that the above-mentioned device is relatively inconvenient to use as a whole, and therefore needs to be improved. Utility Model Content

[0025] The supporting mechanism 2 comprises a cross 21, which is fixedly mounted in the middle of the bottom of the base plate 1. An articulated groove 22 is provided on the outer side of the cross 21, and a telescopic component 23 is rotatably connected to the inner side of the articulated groove 22. The telescopic component 23 is arranged in an outward-facing "X" shape when unfolded. A supporting mechanism 2 is installed at the bottom of the base plate 1 to ensure stable support. A mounting frame 3 is provided on the top, and a leveling ball 4 is rotatably connected inside so that the leveling instrument body 6 can be adaptively leveled. The top of the leveling ball 4 is connected to the leveling instrument body 6 through a support rod 5 to ensure measurement accuracy. The core of the supporting mechanism 2 is a cross 21, which has an articulated groove 22 on the outer side and is rotatably connected to the telescopic component 23 inside. These telescopic components 23 are in an outward-facing "X" shape when unfolded, and the length can be flexibly adjusted to adapt to different terrains. By adjusting the telescopic component 23, it can be ensured that the equipment can work stably at different ground heights or potholes. This design not only improves the adjustment and adaptation capability of the equipment, but also enhances the overall stability, making it more reliable and efficient in ground subsidence monitoring.

[0026] refer to Figure 1-Figure 4 The telescopic component 23 includes a sleeve 231, which is hingedly installed inside the hinge groove 22.

The outer end of the outer side of the sleeve 231 is threadedly connected with a limit screw 236, and the end of the limit screw 236 is inserted into the inner side of the limit hole 233. The outer end of the slide bar 232 is hinged with an anti-sliding block 234, and the bottom of the anti-sliding block 234 is fixedly connected with anti-slip cones 235 at equal intervals. The core of the telescopic component 23 is the sleeve 231, which is hingedly installed inside the hinge groove 22 and allows free rotation within a certain range. The inner side of the sleeve 231 is slidably connected with a slide bar 232, and the bottom of the slide bar 232 passes through the sleeve 231, so that the two can slide relative to each other. In order to flexibly adjust the total length, in order to fix the relative position of the sleeve 231 and the sliding rod 232, limit holes 233 are opened at equal intervals on the outside of the sliding rod 232, and the outer end of the sleeve 231 is threadedly connected to the limit screw 236.

Especially on soft or uneven ground, the role of the anti-slip cone 235 is more significant, which can ensure that the equipment is not easily displaced or tipped over during operation.

[0027] refer to Figure 1-Figure 4A balancing ball 8 is fixedly installed on one side of the bottom of the level measuring instrument body 6, and a mounting groove 9 is opened on one side of the substrate 1, and a battery 10 is fixedly installed inside the mounting groove 9. A balancing ball 8 is fixedly installed on one side of the bottom of the level measuring instrument body 6. This design enables the measuring instrument to be automatically leveled when placed to ensure the accuracy of the measurement result. Regardless of whether the ground is tilted or not, the balancing ball 8 can use gravity to prompt the measuring instrument body to adaptively reach a horizontal state, which greatly simplifies the leveling process and improves work efficiency. In addition, a mounting groove 9 is opened on one side of the substrate 1, and a battery 10 is fixedly installed inside the mounting groove 9. This design enables the measuring instrument to work for a long time without an external power supply, thereby improving its convenience and flexibility in use. The presence of the battery 10 ensures that the level measuring instrument can be stably powered in complex environments or remote areas, providing a reliable energy guarantee for ground subsidence monitoring.

[0028] refer to Figure 1-Figure 4 The bottom of the base plate 1 is fixedly installed with an electric push rod 11, and the output end of the electric push rod 11 passes through the base plate 1 and is fixedly installed with a suction cup 12. The suction cup 12 and the leveling ball 4 are arranged vertically and collinearly. The ground settlement monitoring leveling instrument adds an electric push rod 11 and its matching suction cup 12 device at the bottom of the base plate 1, which further enhances the stability and practicality of the equipment. The output end of the electric push rod 11 passes through the base plate 1 and is fixedly installed with the suction cup 12. This design allows the suction cup 12 to move up and down under the drive of the electric push rod 11. When the telescopic component 23 is adjusted to a suitable length and the leveling is completed, the electric push rod 11 is started to make the suction cup 12 rise and fit tightly. At the bottom of the leveling ball 4, the suction cup 12 is arranged vertically and collinearly with the leveling ball 4, ensuring that the suction cup 12 can accurately align with and adsorb the leveling ball 4. Through the adsorption effect of the suction cup 12, the leveling ball 4 is firmly fixed, thereby making the entire level measuring instrument body 6 in a stable state. This design effectively prevents the level measuring instrument body 6 from shaking or shifting due to external force or vibration during use, thereby improving the measurement accuracy and stability. In addition, the control of the electric push rod 11 can be automated or manual, and can be flexibly adjusted according to actual needs. Through simple operation, the leveling ball 4 can be conveniently fixed or released, making the operation of the entire equipment more convenient and efficient.

[0029] refer to Figure 1-Figure 4A mounting ring 13 is fixedly installed on the outer side of the mounting frame 3, a support rod 14 is fixedly installed in the middle of one side of the mounting ring 13, and a rain shelter 15 is fixedly installed on the top of the support rod 14. A support rod 14 is fixedly installed in the middle of one side of the mounting ring 13, and a rain shelter 15 is fixedly installed on the top of the support rod 14. The design of the rain shelter 15 effectively provides protection for the level measuring instrument to prevent damage to the equipment by rain or other adverse weather conditions. At the same time, the rain shelter 15 can also play a role in shading, reducing the influence of direct sunlight on the measurement accuracy. This series of improved designs not only improves the stability and reliability of the equipment, but also enhances its convenience of use and environmental adaptability. Whether in a complex monitoring environment or in changeable weather conditions, the ground subsidence monitoring level measuring instrument can perform well and provide strong support for ground subsidence monitoring.

[0030] refer to Figure 1-Figure 4 A photovoltaic panel 16 is fixedly installed on the top of the rain shelter 15. The rain shelter 15 is tilted. By integrating the photovoltaic panel 16, not only the practicability of the equipment is enhanced, but also the energy utilization efficiency is improved. The photovoltaic panel 16 fixedly installed on the top of the rain shelter 15 can effectively convert solar energy into electrical energy, and provide a continuous and stable power supply for the level measuring instrument. This design not only reduces the dependence on traditional energy and reduces operating costs, but also conforms to the concept of green environmental protection and is conducive to sustainable development. At the same time, the tilt setting of the rain shelter 15 has also been carefully considered. This design can better utilize solar energy and improve the power generation efficiency of the photovoltaic panel 16. The tilted rain shelter 15 can also effectively guide the flow of rainwater to prevent water accumulation from damaging the equipment. In addition, the tilted rain shelter 15 also has a better shading effect, which can effectively reduce the impact of direct sunlight on the level measuring instrument and improve the measurement accuracy and stability.

[0031] refer to Figure 1-Figure 4 The lower end of the mounting frame 3 is threadedly connected with a hand screw 7, and the bottom of the hand screw 7 passes through the mounting frame 3 and is fitly connected to the top of the base plate 1, and a hand screw 7 with a threaded connection is designed between the lower end of the mounting frame 3 and the base plate 1. This innovation enables the user to adjust and fix the mounting frame 3 more conveniently. By rotating the hand screw 7, the user can adjust the relative position between the mounting frame 3 and the base plate 1 as needed, thereby realizing flexible adjustment of the height and angle of the level measuring instrument body 6. This design not only simplifies the adjustment process and improves work efficiency, but also enables the level measuring instrument to better adapt to different terrains and monitoring needs. At the same time, the bottom of the hand screw 7 passes through the mounting frame 3 and is fitly connected to the top of the base plate 1, ensuring a stable connection between the mounting frame 3 and the base plate 1. This connection method not only ensures the stability of the structure, but also can withstand a certain external force impact, thereby preventing the level measuring instrument from shaking or shifting during use.

[0032] Principle and advantages of use: By setting the mounting frame 3 and the leveling ball 4 inside the mounting frame 3, when the device is placed on the ground during use, the center of the level measuring instrument body 6 can be kept in the middle due to the setting of the balancing ball 8. When the ground is in an inclined state, the leveling ball 4 at the bottom of the level measuring instrument body 6 is located on the inner side of the mounting frame 3 and rotates due to the influence of gravity. The level measuring instrument body 6 is easy to level adaptively, so that during use, the device only needs to be placed on the ground to automatically balance and level. The leveling design using the influence of gravity allows the device to quickly balance during use, which can ensure the overall detection accuracy of the device. At the same time, during the adjustment process, after the leveling is completed, the electric push rod 11 is started to run, and the electric push rod 11 is used to push the suction cup 12 upward. The suction cup 12 moves up to contact the bottom of the leveling ball 4, and the bottom of the leveling ball 4 is fixed, which can ensure that the level measuring instrument body 6 is in a relatively stable state, which can avoid shaking during use, and can improve the stability of measurement and monitoring of the device as a whole during use.

[0033] By setting the telescopic mechanism, the device can be placed on the ground as a whole during use. At this time, by adjusting the sleeve 231 inside the hinge groove 22 to rotate, the sleeve 231 is rotated toward the outside, so that the sleeve 231 and the slide bar 232 are in an outward eight-shaped state. At this time, by adjusting the slide bar 232 and the sleeve 231 to slide against each other, the total length of the sleeve 231 and the slide bar 232 can be flexibly adjusted. When the length adjustment is completed, the hand-screw rod 7 can be movably inserted into the limiting hole 233 at the corresponding position by twisting the hand-screw rod 7. The limiting hole 233 and the limiting screw 236 limit each other, which can assist in limiting and fixing the sleeve 231 and the slide bar 232, so that the device as a whole can have strong stability. In addition, during use, the outer end of the slide bar 232 is hingedly installed with an anti-sliding block 234. At this time, the anti-sliding block The anti-slip cone 235 at the bottom of 234 contacts the ground, and the anti-slip cone 235 can be inserted into the ground, which can make the whole device have strong stability. In addition, due to the flexible adjustment design of the overall height of the sleeve 231 and the slide rod 232 during use, it can adapt to different heights or bumpy ground, which can improve the overall adjustment and adaptation ability of the device. In addition, during use of the device, the battery 10 arranged inside the installation groove 9 cooperates with the photovoltaic panel 16 to convert and store electrical energy. At the same time, the design of the rain shelter 15 can assist in shading protection and can play a better protective role. In addition, the mounting ring 13 is designed to rotate, and when the level measuring instrument adjusts its direction position, the mounting ring 13 can be fixed by twisting the hand screw 7, which is convenient for flexible adjustment and adaptation of the device, which can improve the overall ease of use of the device.
