With the acceleration of urbanization, various large-scale construction projects such as high-rise buildings and large commercial complexes continue to emerge, and the scale and depth of foundation pits are also increasing. During the excavation and subsequent construction process, the foundation pit is very prone to deformation due to the combined influence of various factors such as soil stress changes, groundwater level fluctuations, loads from surrounding buildings, and construction activities. If the deformation exceeds the allowable range, it will pose a serious threat to the structural safety of the foundation pit itself and the surrounding environment. Major accidents such as foundation pit collapse, cracking or even collapse of surrounding buildings, and rupture of underground pipelines will not only cause huge economic losses, but may also endanger people's lives. Therefore, it is crucial to conduct accurate and real-time deformation monitoring of construction foundation pits.

[0022] In this embodiment, when the automatic settlement observation mark is installed inside the foundation pit at the construction site to monitor the status of the foundation pit in real time, the long-term high-intensity work of the equipment at the construction site will generate severe vibrations, and the vibrations generated will be transmitted to the inside of the automatic settlement observation mark, causing the fixing frame 27 to move up and down inside the shell 1.

[0024] In this embodiment, when the automatic sedimentation observation mark is used for a long time, its internal parts will generate a lot of heat. At this time, the air inside the automatic sedimentation observation mark can be circulated quickly under the action of the slots opened on the outer wall of the activated carbon filter plate 14, the dehumidification filter plate 15, and the precision filter plate 16, so that the heat generated by the internal parts of the automatic sedimentation observation mark can be transported out, avoiding the internal parts from being damaged due to excessive temperature, further extending the service life of the automatic sedimentation observation mark. When the air inside the automatic sedimentation observation mark is circulated quickly, the air inside the precision filter plate 16 is used to filter the air. Under the action of the filter, since the precision filter 16 is made of glass fiber, it can filter and adsorb dust and impurities in the air, preventing dust and impurities from entering the automatic sedimentation observation mark, and under the action of the dehumidification filter plate 15, since silica particles are placed inside the dehumidification filter plate 15, the water vapor in the air can be fully absorbed, making the air entering the automatic sedimentation observation mark drier, and then under the action of the activated carbon filter plate 14, the dust, impurities and water vapor in the air can be further adsorbed and filtered, preventing dust, impurities and water vapor from entering the automatic sedimentation observation mark along with the air. The inside of the measuring mark, thereby protecting the internal components of the automatic sedimentation observation mark, avoiding the components from being damaged by the erosion of dust, impurities and water vapor, and extending the service life of the automatic sedimentation observation mark. After a long period of use, a large amount of dust and impurities will adhere to the surface of the activated carbon filter plate 14, the dehumidification filter plate 15, and the precision filter plate 16, which need to be cleaned. At this time, under the operation of the staff, the limit rod 19 is pressed to move inside the installation groove 17, and the limit spring 18 is compressed, so that the limit rod 19 no longer limits and fixes the mounting bracket 13, so that the installation can be easily The rack 13 is taken out from the inside of the fixed groove 12, thereby completing the disassembly of the activated carbon filter plate 14, the dehumidification filter plate 15, the precision filter plate 16 and the mounting rack 13, and then the new filter adsorption filter plate is installed into the inside of the fixed groove 12, and then the limit rod 19 is loosened. Under the action of the limit spring 18, the limit rod 19 can be inserted into the mounting rack 13 and the inside of the shell 1, thereby fixing and limiting the mounting rack 13, realizing rapid installation and disassembly of the mounting rack 13, making it easier to replace the activated carbon filter plate 14, the dehumidification filter plate 15 and the precision filter plate 16, and improving the ventilation and heat dissipation effect inside the automatic sedimentation observation mark.

[0025] Example 3, according to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 as well as Figure 6As shown, two fixing plates 2 are fixedly installed on the outer wall of the shell 1, and the inner walls of the two fixing plates 2 are threadedly connected with a group of fixing bolts 3. Two handles 44 are fixedly installed on the outer wall of the shell 1, and a top cover 4 is provided on the inner wall of the shell 1. Two groups of circular grooves 5 are opened on the outer wall of the top cover 4, and a rotating frame 6 is movably inserted between the inner walls of the two groups of circular grooves 5. A solar panel 7 is fixedly installed on one side of the outer wall of the two rotating frames 6. Two slide grooves 8 are opened on the outer walls of the two rotating frames 6, and sliders 9 are movably embedded in the inner walls of the four slide grooves 8. A cleaning roller 10 is movably inserted between every two of the four sliders 9. The outer walls of the two cleaning rollers 10 are fixedly sleeved with a transmission wheel 11, and the outer wall of the transmission wheel 11 is engaged with the meshing groove opened on the inner wall of the rotating frame 6, the outer wall of the top cover 4 is provided with a sealing ring 20, the outer wall of the top cover 4 is provided with a dust ring 21, the outer wall of the top cover 4 and the outer wall of the outer shell 1 are provided with four groups of limiting grooves 22, and limiting plates 23 are provided between the inner walls of the four groups of limiting grooves 22. A handle 24 is fixedly installed on one side of the outer wall of the four limiting plates 23, and a group of setting grooves 25 are opened on one side of the outer wall of the four limiting plates 23, and the inner walls of the four groups of setting grooves 25 are fixedly installed with a magnetic block 26.

[0026] In this embodiment, when the automatic settlement observation mark is in use, the automatic settlement observation mark can be installed and fixed under the action of the fixing plate 2 and the fixing bolt 3, so as to avoid the displacement of the automatic settlement observation mark during subsequent use, thereby improving the monitoring effect of the foundation pit. After the automatic settlement observation mark is installed, the rotating frame 6 is adjusted to rotate inside the circular groove 5 under the operation of the staff, so as to unfold the solar panel 7. Under the action of the solar panel 7, the inverter and the battery, the solar energy can be converted into electrical energy and stored to power the electronic components inside the automatic settlement observation mark, thereby reducing the consumption of external electrical energy and improving the utilization rate of resources. After a long period of use, a large amount of dust and impurities will adhere to the surface of the solar panel 7, which will seriously affect the conversion of electrical energy. At this time, under the operation of the staff, the sliding block 9 is moved inside the slide groove 8, and the cleaning roller 10 can be driven to rotate under the action of the transmission wheel 11 and the meshing groove. This can clean the dust and impurities on the surface of the solar panel 7, thereby greatly improving the conversion efficiency of electric energy. During use, the sealing ring 20 and the dust ring 21 can prevent external dust and impurities from entering the automatic sedimentation observation mark and affecting its internal components. When the automatic sedimentation observation mark needs to be maintained after a long period of use, the staff can pull the handle 24 to remove the limit plate 23 from the limit groove 22, so that the limit plate 23 no longer plays a limiting role on the top cover 4 and the outer shell 1, so that the top cover 4 can be easily disassembled, which is more convenient for the subsequent maintenance and maintenance of the internal components of the automatic sedimentation observation mark. Then the top cover 4 is set to the inside of the outer shell 1, and the limit plate 23 is placed in the limit groove 22. Under the action of the magnetic block 26, the limit plate 23 can be fixed and limited to prevent the limit plate 23 from falling off, thereby improving the fixing effect of the top cover 4.

[0027] The working principle of the entire mechanism is as follows: when it is necessary to use the automatic settlement observation mark to carry out real-time monitoring of the foundation pit on the construction site, the automatic settlement observation mark can be installed and fixed under the action of the fixing plate 2 and the fixing bolt 3, so as to avoid the displacement of the automatic settlement observation mark during subsequent use, thereby improving the monitoring effect of the foundation pit. After the automatic settlement observation mark is installed, the rotating frame 6 is adjusted to rotate inside the circular groove 5 under the operation of the staff, thereby unfolding the solar panel 7. Under the action of the solar panel 7, the inverter and the battery, the solar energy can be converted into electrical energy and stored to power the electronic components inside the automatic settlement observation mark, thereby reducing the consumption of external electricity and improving the utilization rate of resources. After a long period of use, a large amount of dust and impurities will adhere to the surface of the solar panel 7, which will seriously affect the conversion of electric energy. At this time, under the operation of the staff, the slider 9 is moved inside the slide 8, and under the action of the transmission wheel 11 and the meshing groove, the cleaning roller 10 can be driven to rotate, thereby cleaning the dust and impurities on the surface of the solar panel 7, thereby greatly improving the efficiency of electric energy conversion. When the automatic settlement observation mark is in use, due to the long-term high-intensity work of the construction site equipment, severe vibrations will be generated. The vibrations generated will be transmitted to the inside of the automatic settlement observation mark, causing the fixed frame 27 to move up and down inside the shell 1. Under the action of the fixed block 33 and the connecting rod 32, the movable block 31 can be moved inside the movable groove 28 At the same time, under the action of the mounting block 34 and the connecting rod 35, the connecting block 37 can be made to move downward in the square groove 36, thereby compressing the compression spring 38. When the buffer spring 29 and the compression spring 38 are compressed to a certain extent, a large rebound force will be generated. At this time, under the action of the first damper 30 and the second damper 39, the rebound force generated by the buffer spring 29 and the compression spring 38 can be partially absorbed, thereby avoiding a large rebound force from repeatedly acting on the fixing frame 27, thereby effectively preventing the internal components of the automatic subsidence observation mark from being subjected to severe vibration for a long time, protecting the internal components of the automatic subsidence observation mark, extending its service life, and And through the action of the first damping groove 40, the first movable frame 41, the second damping groove 42 and the second movable frame 43, the monitoring components and sensors inside the automatic settlement observation mark can always be kept vertical to the ground, avoiding the monitoring components and sensors inside the automatic settlement observation mark from tilting greatly during use, thereby improving the monitoring effect of the foundation pit, and after long-term use, the internal components of the automatic settlement observation mark will generate a lot of heat. At this time, through the action of the notches opened on the outer walls of the activated carbon filter plate 14, the dehumidification filter plate 15 and the precision filter plate 16, the air inside the automatic settlement observation mark can circulate quickly, thereby transporting the heat generated by the internal components of the automatic settlement observation mark.It prevents its internal components from being damaged due to excessive temperature, further prolongs the service life of the automatic sedimentation observation mark. When the air inside the automatic sedimentation observation mark circulates quickly, under the action of the precision filter plate 16, since the precision filter 16 is made of glass fiber, it can filter and adsorb dust and impurities in the air, preventing dust and impurities from entering the interior of the automatic sedimentation observation mark. And under the action of the dehumidification filter plate 15, since silica particles are placed inside the dehumidification filter plate 15, it can fully absorb the water vapor in the air, making the air entering the interior of the automatic sedimentation observation mark drier, and then through the activated carbon Under the action of the filter plate 14, the dust, impurities and water vapor in the air can be further adsorbed and filtered to prevent the dust, impurities and water vapor from entering the interior of the automatic sedimentation observation mark along with the air, thereby protecting the internal components of the automatic sedimentation observation mark and preventing the components from being damaged by the erosion of dust, impurities and water vapor, thereby extending the service life of the automatic sedimentation observation mark. After a long period of use, a large amount of dust and impurities will adhere to the surface of the activated carbon filter plate 14, the dehumidification filter plate 15 and the precision filter plate 16, and they need to be cleaned. At this time, under the operation of the staff, the limit rod 19 is pressed to move inside the installation groove 17. The limiting spring 18 is compressed so that the limiting rod 19 no longer limits and fixes the mounting frame 13, so that the mounting frame 13 can be easily taken out from the fixing groove 12, thereby completing the removal of the activated carbon filter plate 14, the dehumidification filter plate 15, the precision filter plate 16 and the mounting frame 13, and then the new filter adsorption filter plate is installed in the fixing groove 12, and then the limiting rod 19 is loosened. Under the action of the limiting spring 18, the limiting rod 19 can be inserted into the mounting frame 13 and the inside of the shell 1, thereby fixing the mounting frame 13 and completing the rapid replacement of the activated carbon filter plate 14, the dehumidification filter plate 15 and the precision filter plate 16. When the automatic sedimentation observation When the marker needs to be maintained after a long period of use, the staff can pull the handle 24 to remove the limit plate 23 from the limit groove 22, so that the limit plate 23 no longer limits the top cover 4 and the shell 1, thereby making it easy to disassemble the top cover 4, which is more convenient for the subsequent maintenance and maintenance of the internal parts of the automatic settlement observation marker. Then, the top cover 4 is set inside the shell 1, and the limit plate 23 is placed inside the limit groove 22. Under the action of the magnetic block 26, the limit plate 23 can be fixed and limited to prevent the limit plate 23 from falling off, thereby improving the fixing effect of the top cover 4.
