[0002] Currently, in various geotechnical and water conservancy projects, it is necessary to accurately detect and continuously monitor the water and soil pressure borne by underground or retaining structures. Existing water and soil pressure detection devices mostly use strain gauges, pressure sensors, or liquid level sensors to convert external pressure into electrical signals for data acquisition. However, during use, the following deficiencies still exist: there is a lack of reset and limit structures. When the monitoring components (such as sliding parts or detection plates) are under pressure for a long time or are subjected to instantaneous impact forces, it is difficult to automatically return to the initial position, requiring manual intervention, increasing maintenance difficulty and inconvenient adjustment. The pressure adjustment mechanism of existing devices is complex or lacks automatic adjustment means, and it is impossible to effectively adjust the detection accuracy and sensitivity according to the on-site working conditions. Therefore, a water and soil pressure detection device is proposed to address the above problems. Summary of the Invention

[0027] Example 1: Please refer to Figure 1-6 , the present invention provides a technical solution:

[0028] A water and soil pressure detection device includes a column 1, a detection box 2, and a main control box 3. The column 1 provides overall support and installation, while the main control box 3 is mounted outside the column 1 and electrically connected to the detection box 2 via wires or cables for data acquisition and signal processing.

[0029] The detection box 2 is mainly composed of a box structure 4, a detection structure 5, an adjustment structure 6 and a detection body 7.

[0030] The housing structure 4 comprises a housing body 41 and a housing cover 42. The interior of the housing body 41 is filled with oil to evenly transmit external pressure to the internal detection components. The housing body 41 and the housing cover 42 are secured together using a fixing plate 44, a sealing gasket 45, and fixing bolts 46, ensuring overall sealing and water and pressure resistance. The fixing plate 44 is positioned around the periphery of the housing body and the housing cover, while the sealing gasket 45 is embedded between the joints to prevent water and sediment from entering the interior.

[0031] Multiple mounting holes 43 are evenly spaced throughout the box body 41 and the box cover 42 for mounting sliding blocks 71. These cylindrical blocks 71 slide axially within the box structure. Each sliding block 71 is prevented from slipping or overtravel by a stop plate 72 at one end. The other end of the stop plate 72 abuts against the box's internal support via a compression spring 73. The compression spring 73 provides axial preload, ensuring the sliding block 71 automatically returns to its original position when no external force is applied.

[0032] To further achieve precise guidance, a guide post 74 is provided in the hollow portion of compression spring 73. This post 74 is inserted into a guide hole within slide block 71, slidingly engaging the slide block to prevent deflection or tilting. A fixing base 75 is mounted on the other end of guide post 74, which is fixedly connected to support rod 76 to enhance overall stability.

[0033] A temperature sensor 8 is installed on one side of the box structure 4 for detecting the ambient temperature in real time and providing a basis for temperature compensation or data correction.

[0034] A detection structure 5 and an adjustment structure 6 are respectively provided at both ends of the detection box 2, both of which are detachably connected to the box cover 42 through the installation slot 47, so as to facilitate maintenance and replacement.

[0035] The detection structure 5 comprises a detection chamber 51, within which is housed an axially movable detection plate 52. One end of the detection plate 52 is connected to a displacement sensor 54 via a transmission rod 53. The displacement sensor 54 is fixed to the inner wall of the detection chamber 51 and detects the displacement of the detection plate 52 and transmits the signal back to the main control box 3. The detection plate 52 moves axially under the influence of external water and soil pressure, converting the pressure into mechanical travel, which is then transmitted to the sensor via the transmission rod.

[0036] A return spring 55 is also installed within the detection chamber 51. One end of the return spring is fixed to the bottom of the detection chamber, and the other end is connected to the detection plate 52. This spring is used to automatically return the detection plate 52 to its initial position when external pressure is removed. To prevent the detection plate 52 from overtravel or overextension, a limit rope 56 is installed within the return spring 55. The ends of the limit rope 56 are respectively fixed to the detection plate 52 and the detection chamber, limiting the maximum displacement of the detection plate 52.

[0037] The adjustment structure 6 is mainly used to adjust and compensate for the internal oil or the force on the detection plate. The adjustment structure 6 includes an adjustment chamber 61 and an adjustment plate 62. The adjustment plate 62 is axially slidably installed inside the adjustment chamber 61, and the volume of the partial cavity in the box body is changed by the adjustment plate 62, thereby adjusting the internal pressure. One end of the adjustment plate 62 is connected to the adjustment mechanism. The adjustment mechanism includes a control motor 63, a threaded rod 64 and a threaded barrel 65. The control motor 63 is fixed inside the adjustment chamber 61, and the motor output shaft is connected to the threaded rod 64. The threaded rod 64 is screwed to the threaded barrel 65, and the threaded barrel 65 is fixed to the adjustment plate 62. After the motor is powered on, the threaded rod 64 is rotated, and the adjustment plate 62 is pushed back and forth through the spiral transmission to achieve precise adjustment.

[0038] Workflow: Device installation and fixation: First, according to the project requirements, reserve installation holes or excavate detection cavities at predetermined locations such as underground monitoring wells, foundation pits, tunnel linings, or dam slope protection. Fix the column 1 firmly and vertically on the foundation or structural support surface to ensure that the device is in a stable state. Install the detection box 2 at the designated test location and check whether its fixing plate 44, sealing gasket 45, and fixing bolts 46 are evenly tightened to avoid leakage. Install the main control box 3 at a suitable position outside the column and complete the electrical connection with the detection structure 5, adjustment structure 6, and temperature sensor 8 of the detection box 2 through cables.

[0039] Initial adjustment and calibration: Power on the main control box 3 to check whether the communication between various components is normal. The main control box controls the motor 63 to drive the threaded rod 64, adjust the position of the threaded barrel 65 and the adjustment plate 62, and make the oil pressure inside the box structure 4 reach the set initial pressure zero point calibration. Confirm that the sliding block 71 is in the restrained position of the upper limit plate 72 when not under pressure, the detection plate 52 is in the elastic pre-load state of the return spring 55, and the displacement sensor 54 reads zero or the set baseline value;

[0040] Pressure detection process: When the surrounding water and soil pressure gradually increases, the sliding block 71 moves axially downward along the guide column 74 under the action of pressure, overcoming the elastic resistance of the compression spring 73, and then squeezing the oil. Under the action of the oil, the detection plate 52 moves axially inside the detection chamber 51, pushing the transmission rod 53 to contact the displacement sensor 54. The displacement sensor collects stroke displacement data in real time, and the displacement sensor transmits the detection signal to the main control box 3. Combined with the temperature data detected by the temperature sensor 8, the main control box 3 performs temperature correction and amplification processing on the pressure signal. The main control box 3 displays the corrected pressure data on the display screen or remotely transmits it to the monitoring center;

[0041] Automatic reset: When the water and soil pressure is reduced or removed, the sliding block 71 automatically moves back along the guide column 74 under the action of the compression spring 73 and returns to its initial position. The limit plate 72 prevents it from exceeding the upper limit of travel. The detection plate 52 automatically retracts under the elastic force of the reset spring 55. At the same time, the limit rope 56 limits its movement range to prevent the spring from being overstretched. The main control box 3 receives the reset completion status and clears the data or records it as the pressure unloading state.

[0042] Adjustment and retesting: If zero point offset is required, the main control box 3 is used to control the motor 63 to rotate the threaded rod 64 again, fine-tune the position of the adjustment plate 62, change the internal oil volume and initial pressure, and after the adjustment is completed, repeat the calibration steps to confirm that the detection plate 52 and the sliding block 71 are in the preloaded state. The subsequent pressure changes can be used to continue testing without disassembling the equipment;

[0043] Maintenance and disassembly: When the device needs to be repaired or replaced, loosen the fixing bolts 46, separate the box cover 42 and the box body 41, take out the sliding block 71, guide column 74, compression spring 73, detection plate 52 and transmission rod 53 in turn, check and replace the sealing gasket 45, replace or replenish the oil to ensure the sealing performance, restore and install the components, complete the seal reset, and recalibrate before putting it into use.
