[0005] The technical problem solved by the utility model is as follows:

[0006] Subway foundation pit underground water level intelligent real time monitoring device, including support, the movable side plate is rotationally installed with pivot, the pivot is wound with pull line, the end of pull line is tied with detector;

[0007] The both ends of pivot are respectively equipped with movable side plate and fixed side plate, the opposite surface of movable side plate and fixed side plate is equipped with support plate, support module is equipped on pivot, support module is located between support plate and pivot, and support plate is supported by support module;

[0011] The beneficial effects of the above further scheme are:

[0012] By designing the outer edge of the limiting plate to be wavy and clamping the limiting wheel with the concave surface, the rotating shaft can be locked at multiple specific positions. In actual use, when the detector needs to be fixed at a certain depth for water level monitoring, the limiting wheel can be clamped into the concave surface of the limiting plate, thereby effectively preventing the rotating shaft from rotating accidentally, ensuring the stability of the detector position, and further improving the accuracy and reliability of the water level monitoring data.

[0013] Further, the rotating shaft is provided with a tooth plate at one end where the movable side plate is installed, the movable side plate is provided with a limiting block, and the movable side plate is limited in position on the rotating shaft by the limiting block and the tooth plate.

[0014] The beneficial effects of the above further scheme are:

[0015] This design gives the movable side plate the function of adjusting the position on the rotating shaft. Since different subway foundation pits have different depths, the length of the pull wire also varies. By cooperating the limiting block with the tooth plate, the position of the movable side plate can be easily adjusted, thereby changing the length of the pull wire accommodated between the fixed side plate and the movable side plate, making the device adapt to water level monitoring work in multiple foundation pit depths, expanding the application range of the device and reducing the cost of customizing different specifications of the device due to the difference in foundation pit depth.

By operating the transmission belt, the threaded rods between multiple adjacent support rib plates can be simultaneously driven to move, thereby realizing synchronous adjustment of the positions of the support rib plates. This greatly improves the efficiency of adjusting the support module, so that the support structure can quickly adapt to different working states. For example, when the device bears different pulling forces, the distance between the support rib plates can be quickly adjusted to enhance the support effect on the rotating shaft, thereby ensuring the stability and reliability of the device as a whole and prolonging the service life of the device.

[0022] Further, the transmission sleeve is provided with a threaded sleeve, the threaded sleeve is in threaded engagement with the threaded rod, a transmission gear is arranged on the threaded sleeve, a positioning frame is sleeved on the threaded sleeve, a pressure roller is rotatably installed on the threaded sleeve through the positioning frame, and the transmission belt is located between the pressure roller and the transmission gear, the transmission belt drives the transmission gear to rotate, and the threaded sleeve rotates.

[0024] The arrangement of the pressure roller ensures the close contact between the transmission belt and the transmission gear, effectively improves the transmission efficiency, and reduces the energy loss and slipping phenomenon in the power transmission process. When the transmission belt drives the transmission gear to rotate, the threaded sleeve converts the circular motion into linear motion under the threaded engagement with the threaded rod, thereby realizing accurate adjustment of the distance between adjacent support rib plates. The positioning frame supports and positions the threaded sleeve, ensures that the threaded sleeve remains stable during rotation and movement, and makes the adjustment of the support module more accurate and controllable, thereby providing more stable and reliable support for the rotating shaft and ensuring the normal operation of the device and the accuracy of water level monitoring.

[0040] Embodiment one

[0041] The utility model provides an intelligent real -time monitoring device of subway foundation pit underground water level, including support 10, the rotatory installation has the pivot 13 on movable side plate 1, the pivot 13 is wound with the guy 4, the end of guy 4 is tied with detector 9, and the both ends of pivot 13 are equipped with movable side plate 1 and fixed side plate 5 respectively, and the opposite surface of movable side plate 1 and fixed side plate 5 is equipped with support plate 2, and the pivot 13 is equipped with support module 3, and support module 3 is located between support plate 2 and pivot 13, and support plate 2 is supported through support module 3, and support module 3 is equipped with support rib plate 302, and support rib plate 302 is equipped with threaded rod 308, and the threaded rod 308 between adjacent two support rib plate 302 is connected through transmission sleeve 301, and transmission sleeve 301 is installed with transmission belt 303, and this structure forms a linkage's support adjusting system.When the position of the movable side plate 1 is adjusted, the clamping teeth 1101 are automatically clamped with the tooth plate 12 under the elastic force of the torsional spring, without the need for additional complex operations to fix the movable side plate 1. Moreover, the continuous elastic force provided by the torsional spring can ensure that the clamping teeth 1101 are tightly combined with the tooth plate 12, so that even if the device is disturbed by vibration or other external forces during operation, the movable side plate 1 can be effectively prevented from shifting, ensuring the stability of the device structure and the continuity of the monitoring work. The movable side plate 1 is limited in position on the rotating shaft 13 by the limiting block 11 and the tooth plate 12, which gives the movable side plate 1 the function of position adjustment on the rotating shaft 13. Because different subway foundation pits have different depths, the length of the pull wire 4 also needs to be different. Through the cooperation of the limiting block 11 and the tooth plate 12, the position of the movable side plate 1 can be easily adjusted, thereby changing the length of the pull wire 4 that can be accommodated between the fixed side plate 5 and the movable side plate 1, so that the device can adapt to water level monitoring work of various foundation pit depths, expand the application range of the device, and reduce the cost of customizing different specifications of the device due to the difference in foundation pit depth.

[0042] Example two

[0043] In order to prevent the rotating shaft 13 from accidentally rotating, ensure the stability of the position of the detector 9, and further improve the accuracy and reliability of the water level monitoring data, as shown in Figures 1 to 5 the utility model also includes: the fixed side plate 5 is welded and fixed with the rotating shaft 13, the fixed side plate 5 is connected with the limiting plate 6 through bolts, the spring seat 8 is installed below the limiting plate 6, the limiting wheel 7 is arranged at the top end of the spring seat 8, the limiting plate 6 is extruded through the limiting wheel 7, the outer edge of the limiting plate 6 is wavy, the limiting wheel 7 is clamped with the concave surface of the limiting plate 6, the rotating shaft 13 is locked through the limiting wheel 7, and the outer edge of the limiting plate 6 is designed to be wavy, which is clamped with the concave surface of the limiting wheel 7, so that the rotating shaft 13 can be locked at multiple specific positions. In actual use, when it is necessary to fix the detector 9 at a certain depth for water level monitoring, the limiting wheel 7 can be clamped into the concave surface of the limiting plate 6, so that the rotating shaft 13 can be effectively prevented from accidentally rotating, the stability of the position of the detector 9 can be ensured, and the accuracy and reliability of the water level monitoring data can be further improved. In addition, the wavy design makes the locking position adjustable, which can adapt to different monitoring requirements and improve the flexibility and applicability of the device.

[0044] Working principle:

[0045] The whole monitoring device is installed on the support 10 in a suitable position of the subway foundation pit. The fixed side plate 5 is stably connected with the support 10 through bolts, so as to ensure the position of the whole device. The detector 9 is tied to the end of the pull wire 4, and the pull wire 4 is wound on the rotating shaft 13. The rotating shaft 13 is rotatably installed between the movable side plate 1 and the fixed side plate 5. The support plates 2 arranged on the opposite surfaces of the movable side plate 1 and the fixed side plate 5 preliminarily support the rotating shaft 13, so as to ensure the stability of the rotating shaft 13 in the initial state. According to the required depth of the detector 9 lowered, the length of the pull wire 4 needed to be accommodated between the fixed side plate 5 and the movable side plate 1 is determined. By adjusting the position of the movable side plate 1 on the rotating shaft 13, the pull wire 4 with different lengths can be accommodated between the fixed side plate 5 and the movable side plate 1. Specifically, the limiting block 11 on the movable side plate 1 cooperates with the toothed plate 12 at one end of the rotating shaft 13. After the fixing of the limiting block 11 and the toothed plate 12 is loosened, the movable side plate 1 can be slid along the rotating shaft 13 to the appropriate position, and then the limiting block 11 and the toothed plate 12 are fixed again. The limiting block 11 and the toothed plate 12 are only used to fix the position of the movable side plate 1, and do not lock the rotating shaft 13.

[0046] After confirming that the position of the movable side plate 1 is adjusted, the rotating shaft 13 is manually rotated. Since the limiting block 11 and the toothed plate 12 do not lock the rotating shaft 13, the movable side plate 1 will rotate together with the rotating shaft 13. The rotating of the rotating shaft 13 drives the pull wire 4 wound thereon to be released, because the detector 9 is tied to the end of the pull wire 4, the detector 9 gradually descends into the foundation pit along with the release of the pull wire 4. With the rotation of the rotating shaft 13, the limiting plate 6 on the fixed side plate 5 has a wavy outer edge, and the limiting wheel 7 at the top end of the spring seat 8 below the limiting plate 6 will roll on the surface of the limiting plate 6. When the limiting wheel 7 rolls to the concave surface of the limiting plate 6, the limiting plate 6 will be extruded, and then a certain resistance to the rotating shaft 13 is generated, so as to limit the too fast rotation of the rotating shaft 13, and ensure the stable lowering of the detector 9.

[0047] If the support module 3 needs to be adjusted to better support the rotating shaft 13 during the detector 9 lowering process or according to actual monitoring needs, the transmission belt 303 can be manually operated. The transmission belt 303 is installed on the transmission sleeve 301, and the transmission sleeve 301 is connected to the threaded rod 308 between adjacent support rib plates 302. When the transmission belt 303 is driven, the transmission belt 303 drives the transmission sleeve 301 to rotate, and the threaded sleeve 306 on the transmission sleeve 301 is in threaded engagement with the threaded rod 308. As the transmission sleeve 301 rotates, the threaded sleeve 306 moves on the threaded rod 308. The threaded sleeve 306 is provided with a transmission gear 307, and the transmission belt 303 drives the transmission gear 307 to rotate the threaded sleeve 306 and move along the threaded rod 308. The threaded sleeve 306 is sleeved with a positioning frame 305, and the positioning frame 305 is rotatably installed with a pressure roller 304. The pressure roller 304 ensures that the transmission belt 303 is in close contact with the transmission gear 307, and ensures that the transmission is effective. As the threaded sleeve 306 moves, the distance between the adjacent support rib plates 302 is adjusted, thereby changing the shape of the support module 3 and better supporting the rotating shaft 13 to adapt to different working states.

[0048] When the detector 9 reaches the specified monitoring depth, the rotating shaft 13 is stopped. At this time, although the limiting block 11 and the tooth plate 12 do not lock the rotating shaft 13, the position of the movable side plate 1 has been adjusted in advance and fixed, which can ensure that the position of the detector 9 is relatively fixed and stable for real-time monitoring of the underground water level. The detector 9 transmits the monitored underground water level data to the monitoring terminal in real time through the corresponding data transmission mode (such as wireless transmission, the specific transmission mode is not specified in the given text, and it is assumed to be a common wireless transmission mode), for the staff to view and analyze.

[0049] The rotating shaft 13 is manually reversed, and since the limiting block 11 and the tooth plate 12 do not lock the rotating shaft 13, the movable side plate 1 will be reversed together with the rotating shaft 13, so that the pull wire 4 is rewound on the rotating shaft 13, driving the detector 9 to rise and be recovered. During the process, the limiting wheel 7 also rolls on the wavy outer edge of the limiting plate 6, which limits the rotation of the rotating shaft 13 to some extent and ensures the stable recovery of the detector 9. After the detector 9 is recovered, according to the next use requirement, if it is necessary to adjust the length of the pull wire 4 accommodated between the fixed side plate 5 and the movable side plate 1, the fixing of the limiting block 11 and the tooth plate 12 can be loosened again, the position of the movable side plate 1 is adjusted, and then it is fixed again, so that the device returns to the state ready for use at any time, and is ready for the next monitoring.

[0050] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application should be covered within the protection scope of the present application.
