Description

Technical Field

[0001] This utility model relates to the field of seepage monitoring technology, and in particular to a real-time seepage monitoring device for pump station foundations. Background Technology

[0002] Groundwater seepage refers to the phenomenon of groundwater flowing through the soil of a foundation, infiltrating from one aquifer to another, or from an aquifer to the surface. This seepage can cause the groundwater level to rise or fall, thus affecting the stability of the foundation and the base of buildings. Groundwater seepage can cause many problems. For example, it can lead to foundation deformation and settlement, thus adversely affecting buildings. Furthermore, groundwater seepage can also cause groundwater pollution, posing a threat to the environment and human health.

[0003] Currently, seepage monitoring is mostly carried out using pressure sensors. Pipes are pre-buried, and then the pressure sensor extends into the soil layer for continuous monitoring. In the initial use, it can meet the established monitoring requirements. However, in subsequent use, when the pressure sensor is replaced due to damage, it is difficult to extend to the original position again because of the water, mud or sand in the pressure measuring pipe, and the fact that the sensor signal line is relatively soft. This results in elevation errors, which have a certain adverse effect on the seepage monitoring and analysis results.

[0004] Therefore, a real-time monitoring device for seepage in pump station foundations is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a real-time monitoring device for seepage in the foundation of a pumping station, which solves the aforementioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a real-time monitoring device for seepage in a pump station foundation, comprising a sleeve, an inner tube detachably installed inside the sleeve, a threaded cap detachably installed on the top of the inner tube, a seepage pressure sensor installed at the bottom of the threaded cap, a support rod fixedly installed at the bottom of the seepage pressure sensor, a sensing head fixedly installed at the end of the support rod away from the seepage pressure sensor, the sensing head being electrically connected to the seepage pressure sensor, a hollow plate fixedly installed at the bottom of the sleeve, a rotating shaft rotatably mounted through the surface of the hollow plate, an adjusting plate fixedly installed on the surface of the rotating shaft, monitoring holes through the surface of the hollow plate, a piston sleeve of the adjusting plate fitted onto the inner wall of the hollow plate and corresponding to the position of the monitoring holes, and a baffle fitted against the top of the hollow plate, the baffle being movably fitted against the sensing head.

[0007] Preferably, a fixing plate is fixedly sleeved on the upper end of the sleeve, an L-shaped slot is provided on the side wall of the fixing plate, a locking block is slidably engaged on the inner wall of the L-shaped slot, a connecting plate is fixedly sleeved on the upper end of the inner tube, the locking block is fixedly installed on the side wall of the connecting plate, a threaded annular groove is provided in the top of the connecting plate, and the bottom of the threaded cap is threadedly sleeved on the inner wall of the threaded annular groove.

[0008] Preferably, the inner wall of the inner tube is recessed and has a sliding groove, and a slider is slidably sleeved on the inner wall of the sliding groove, and the slider is fixedly installed on the side wall of the baffle.

[0009] Preferably, a cross-shaped insert is fixedly installed at the bottom of the baffle, and a cross-shaped slot is recessed at the top of the rotating shaft, with the cross-shaped insert slidingly inserted into the inner wall of the cross-shaped slot.

[0010] Preferably, a plug rod is fixedly installed at the bottom of the fixing plate, and the plug rod has a symmetrical structure with the sleeve as the center.

[0011] Preferably, a rubber pad is fixedly sleeved on the surface of the card block.

[0012] Compared with related technologies, the real-time monitoring device for seepage in pump station foundations provided by this utility model has the following beneficial effects:

[0013] This utility model provides a real-time monitoring device for seepage in pump station foundations. The device involves pre-embedding a casing at the monitoring point, then installing an inner tube inside the casing, and finally threading a threaded cap onto the inner tube. This completes the installation of the pressure sensor inside the casing. After the pressure sensor is installed, the sensing head fits against the baffle, ensuring that seepage water entering the baffle through the monitoring hole can be monitored in real-time via the sensing head and the pressure sensor. Furthermore, when the pressure sensor needs replacement, it is not necessary to remove the entire casing for disassembly, effectively reducing the maintenance cost of the pressure sensor and improving monitoring efficiency.

[0014] This utility model provides a real-time monitoring device for seepage in the foundation of a pumping station. After the inner tube is inserted into the casing, the cross-shaped insert is inserted into the inner wall of the cross slot. Then, during the rotation of the connecting plate, the cross-shaped insert drives the rotating shaft to rotate, which in turn causes the adjusting plate to slide on the inner wall of the hollow plate. This allows the mud and water in the monitoring point to enter the casing through the monitoring point and squeeze the baffle. When the inner tube is disassembled, the adjusting plate is driven to rotate in the opposite direction, so that the adjusting plate seals the monitoring hole and prevents the mud and water from filling the inside of the casing.

Detailed Implementation

[0022] Please see Figures 1-6 This utility model provides a technical solution, including a sleeve 1, an inner tube 19 detachably installed inside the sleeve 1, a threaded cap 16 detachably installed on the top of the inner tube 19, a pressure sensor 27 installed at the bottom of the threaded cap 16, a support rod 28 fixedly installed at the bottom of the pressure sensor 27, a sensing head 29 fixedly installed at the end of the support rod 28 away from the pressure sensor 27, the sensing head 29 being electrically connected to the pressure sensor 27, a hollow plate 17 fixedly installed at the bottom of the sleeve 1, a rotating shaft 25 rotatably installed through the surface of the hollow plate 17, an adjusting plate 24 fixedly installed on the surface of the rotating shaft 25, a monitoring hole through the surface of the hollow plate 17, a piston sleeve of the adjusting plate 24 being fitted onto the inner wall of the hollow plate 17 and corresponding to the position of the monitoring hole, and a baffle 22 fitted to the top of the hollow plate 17, the baffle 22 being movably fitted to the sensing head 29;

[0023] By pre-embedding the sleeve 1 at the monitoring point, then installing the inner tube 19 inside the sleeve 1, and finally threading the threaded cap 16 to the inner tube 19, the pressure sensor 27 is installed inside the sleeve 1. After the pressure sensor 27 is installed, the sensing head 29 fits against the baffle 22, ensuring that the seepage water can be monitored in real time through the sensing head 29 and the pressure sensor 27 after entering the pressure baffle 22 through the monitoring hole. When the pressure sensor 27 needs to be replaced, it is not necessary to remove the entire sleeve 1 for disassembly, which effectively reduces the maintenance cost of the pressure sensor 27 and improves the monitoring efficiency.

[0024] A fixing plate 11 is fixedly sleeved on the upper end of the sleeve 1. An L-shaped slot 13 is opened on the side wall of the fixing plate 11. A locking block 15 is slidably engaged on the inner wall of the L-shaped slot 13. A connecting plate 14 is fixedly sleeved on the upper end of the inner tube 19. The locking block 15 is fixedly installed on the side wall of the connecting plate 14. A threaded annular groove 18 is recessed in the top of the connecting plate 14. The bottom of the threaded cap 16 is threadedly sleeved on the inner wall of the threaded annular groove 18.

[0025] First, insert the sleeve 1 inside and align the locking block 15 with the L-shaped slot 13. Then, rotate the connecting plate 14 to make the locking block 15 slide on the inner wall of the L-shaped slot 13. When the locking block 15 moves to the end of the inner wall of the L-shaped slot 13, the inner tube 19 is installed. Then, gradually thread the threaded cap 16 to the connecting plate 14 through the threaded annular groove 18 to complete the threaded installation, thereby enabling the pressure sensor 27 to be installed inside the sleeve 1, so as to facilitate the device to monitor the monitoring point in real time.

[0026] The inner wall of the inner tube 19 is recessed and has a groove 2. A slider 21 is slidably sleeved on the inner wall of the groove 2. The slider 21 is fixedly installed on the side wall of the baffle 22.

[0027] After the device is installed, the slider 21 slides within the inner wall of the groove 2, allowing the baffle 22 to move piston-like within the inner wall of the inner tube 19. This isolates the mud and water at the monitoring point, reducing the negative impact on the pressure sensor 27 and ensuring the accuracy of the seepage monitoring results.

[0028] A cross-shaped insert 23 is fixedly installed at the bottom of the baffle 22, and a cross-shaped slot 26 is recessed at the top of the rotating shaft 25. The cross-shaped insert 23 is slidably inserted into the inner wall of the cross-shaped slot 26.

[0029] After the inner tube 19 is inserted into the sleeve 1, the cross-shaped insert 23 is inserted into the inner wall of the cross-shaped slot 26. Then, during the rotation of the connecting plate 14, the cross-shaped insert 23 drives the rotating shaft 25 to rotate, which in turn causes the adjusting plate 24 to slide on the inner wall of the hollow plate 17. This allows the mud and water in the monitoring point to enter the sleeve 1 through the monitoring point and squeeze the baffle 22. When the inner tube 19 is disassembled, the adjusting plate 24 is driven to rotate in the opposite direction, so that the adjusting plate 24 blocks the monitoring hole and prevents the mud and water from filling the inside of the sleeve 1.

[0030] A plug rod 12 is fixedly installed at the bottom of the fixing plate 11. The plug rod 12 has a symmetrical structure with the sleeve 1 as the center.

[0031] After the sleeve 1 is buried in the monitoring point, the insertion rod 12 is inserted into the ground to make the installation of the sleeve 1 inside the monitoring point more stable.

[0032] The surface of the card block 15 is fixed with a rubber pad;

[0033] This effectively increases the friction of the card block 15 on the inner wall of the L-shaped slot 13, preventing the inner tube 19 from shifting during the monitoring process and affecting the monitoring effect.
