Description

Technical Field

[0001] This utility model relates to the field of hydrostatic pressure monitoring technology, and in particular to a device for monitoring the hydrostatic pressure of groundwater in a mine after the mine is sealed. Background Technology

[0002] In hydrological safety monitoring after mine closure, hydrostatic pressure is one of the core parameters for judging the risks of water inrush in the goaf, overflow of confined water in the floor, and leakage of the sealing wall. Existing technologies generally use piezoresistive or vibrating wire piezometers installed in boreholes in the sealing wall or surrounding rock for long-term monitoring. Due to the complex environment inside the mine, there is not only continuous mechanical vibration (such as vibration caused by the transmission of surrounding mining operations and the release of rock stress), but also periodic fluctuations in groundwater pressure. Traditional installation methods rely solely on expansion bolts or simple clamps to bind the probe to the borehole wall or wall. Under repeated impacts from vibration and pulsed water pressure, the probe of the device is prone to loosening and slippage at the fastening points, which cannot accurately reflect the true hydrostatic pressure data.

[0003] In summary, this application proposes a groundwater hydrostatic pressure monitoring device for mine tunnels after sealing to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a groundwater hydrostatic pressure monitoring device for mines after sealing. This device addresses the problem that existing technologies commonly use piezoresistive or vibrating wire piezometers installed in boreholes within the sealing wall or surrounding rock for long-term monitoring. Due to the complex environment within mines, there is not only continuous mechanical vibration (such as vibrations transmitted from surrounding mining operations or caused by stress release in the rock strata) but also periodic fluctuations in groundwater pressure. Traditional installation methods rely solely on expansion bolts or simple clamps to bind the probe to the borehole wall or wall. Under repeated impacts from vibration and pulsed water pressure, the probe of the device is prone to loosening and slippage at the fastening points, failing to accurately reflect the true hydrostatic pressure data.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a groundwater hydrostatic pressure monitoring device in a mine after mine tunnel sealing, comprising a detection probe and a support assembly. The support assembly is located on the detection probe and includes a support plate, a connecting sleeve, a slide groove, a clamping plate, a sliding rod, a mounting spring, a limiting plate, a hinge rod, a ring plate, a mounting sleeve, and a threaded cylinder. The connecting sleeve is fixedly connected to the front side of the support plate, and the threaded cylinder is fixedly connected to the rear side of the support plate.

[0006] Preferably, the abutment plate is provided with sliding grooves, and the number of sliding grooves is four sets arranged in a circular array, which facilitates the movement of the clamping plate.

[0007] Preferably, a slide rod is fixedly connected inside the slide groove, a clamping plate is slidably mounted on the slide rod, a mounting spring is fixedly connected to one side of the clamping plate, and one end of the mounting spring is fixedly connected to the inner wall of one side of the slide groove.

[0008] Preferably, a limiting plate is fixedly connected inside the connecting sleeve, and one end of the detection probe is snapped into the connecting sleeve. Openings are provided on the abutment, connecting sleeve, and threaded cylinder for the connecting wire on the detection probe to pass through.

[0009] Preferably, the outer wall of the threaded cylinder is threaded with an installation sleeve, and the outer wall of the installation sleeve is rotatably connected to a ring plate. A hinge rod is hinged to the ring plate, and one end of the hinge rod is hinged to a clamping plate. Through the coordinated use of the abutment plate, connecting sleeve, slide groove, clamping plate, slide rod, installation spring, limiting plate, hinge rod, ring plate, installation sleeve, and threaded cylinder, the detection probe can be kept stable in the predetermined position, thereby ensuring the stability of the measurement. The environment inside the mine is complex, and vibration and water pressure fluctuations have a significant impact on the equipment. By fixing the detection probe, the influence of these external factors on the monitoring device can be effectively reduced, the service life of the equipment can be extended, the maintenance costs caused by equipment loosening or damage can be reduced, and the device can continuously and effectively monitor water pressure, avoiding errors caused by positional deviation and ensuring the acquisition of accurate hydrostatic pressure data.

[0010] Preferably, the clamp has multiple sets of anti-slip textures, which facilitate the use of the device by preventing slippage.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: After the mine is sealed, the groundwater hydrostatic pressure monitoring device in the mine can ensure that the detection probe is stably in the predetermined position through the coordinated use of a retaining plate, connecting sleeve, slide groove, clamping plate, sliding rod, mounting spring, limiting plate, hinge rod, ring plate, mounting sleeve and threaded cylinder, thereby ensuring the stability of the measurement. The environment inside the mine is complex, and vibration and water pressure fluctuations have a large impact on the equipment. By fixing the detection probe, the influence of these external factors on the monitoring device can be effectively reduced, the service life of the equipment can be extended, the maintenance cost caused by equipment loosening or damage can be reduced, and the device can continuously and effectively monitor water pressure, avoid errors caused by position deviation, and ensure that accurate hydrostatic pressure data is obtained.

[0017] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] Please see Figure 1-3This utility model provides a technical solution: a device for monitoring the hydrostatic pressure of groundwater in a mine after mine closure, comprising a detection probe 1 and a support assembly. The support assembly is located on the detection probe 1 and includes a support plate 2, a connecting sleeve 3, a slide groove 4, a clamping plate 5, a sliding rod 6, a mounting spring 7, a limiting plate 8, a hinge rod 9, a ring plate 10, a mounting sleeve 11, and a threaded cylinder 12. The connecting sleeve 3 is fixedly connected to the front side of the support plate 2, and the threaded cylinder 12 is fixedly connected to the rear side of the support plate 2. The support plate 2 has a slide groove 4, which is arranged in four groups in a circular array to facilitate the movement of the clamping plate 5. The sliding rod 6 is fixedly connected inside the slide groove 4, and the clamping plate 5 is slidably mounted on the sliding rod 6. A mounting spring 7 is fixedly connected to the side, with one end of the mounting spring 7 fixedly connected to the inner wall of one side of the slide 4. A limit plate 8 is fixedly connected inside the connecting sleeve 3. One end of the detection probe 1 is snapped into the connecting sleeve 3. The abutment plate 2, the connecting sleeve 3, and the threaded cylinder 12 are all provided with openings for the connecting wire of the detection probe 1 to pass through. A mounting sleeve 11 is threaded onto the outer wall of the threaded cylinder 12. A ring plate 10 is rotatably connected to the outer wall of the mounting sleeve 11. A hinge rod 9 is hinged onto the ring plate 10. One end of the hinge rod 9 is hinged to the clamping plate 5. In use, the worker drills a hole in the inner wall of the mine, then inserts the end of the detection probe 1 with the connecting wire into the connecting sleeve 3 for fixation, and then places it in the mine. Inside the borehole, the front side of the abutment plate 2 is positioned against the outer edge of the borehole. Then, the mounting sleeve 11, threaded onto the outer wall of the threaded cylinder 12, is rotated. Since the mounting sleeve 11 and the threaded cylinder 12 are threaded together, the mounting sleeve 11 moves axially along the threaded cylinder 12 during rotation. A ring plate 10 is rotatably connected to the outer wall of the mounting sleeve 11. The axial movement of the mounting sleeve 11 causes the ring plate 10 to move synchronously. A hinge rod 9 is hinged to the ring plate 10, and the other end of the hinge rod 9 is hinged to the clamping plate 5. Therefore, the movement of the ring plate 10 pushes or pulls the clamping plate 5 through the hinge rod 9. Under the force of the hinge rod 9, the clamping plate 5 slides radially along the sliding rod 6 until the outer wall of the clamping plate 5 is tightly pressed against the inner wall of the mine tunnel, preventing the device from... Due to slippage caused by mine vibration or water pressure impact, the detection probe 1 can be kept stable in a predetermined position by the coordinated use of the abutment plate 2, connecting sleeve 3, slide groove 4, clamping plate 5, slide rod 6, mounting spring 7, limiting plate 8, hinge rod 9, ring plate 10, mounting sleeve 11, and threaded cylinder 12, thereby ensuring the stability of the measurement. The environment inside the mine is complex, and vibration and water pressure fluctuations have a significant impact on the equipment. By fixing the detection probe 1, the influence of these external factors on the monitoring device can be effectively reduced, the service life of the equipment can be extended, the maintenance costs caused by equipment loosening or damage can be reduced, and the device can continuously and effectively monitor water pressure, avoiding errors caused by positional deviation and ensuring the acquisition of accurate hydrostatic pressure data.

[0019] Furthermore, multiple anti-slip patterns are provided on the clamping plate 5, which facilitates the use of the device and prevents slippage. The spring 7 provides buffering force when the clamping plate 5 is pressed against the inner wall of the mine tunnel, compensating for minor unevenness of the inner wall of the mine tunnel, enhancing the stability of the fixation, and at the same time preventing the clamping plate 5 from being damaged by excessive pressure due to rigid contact.

[0020] Working principle: During use, the operator drills a hole in the inner wall of the mine. Then, the end of the detection probe 1 with the connecting wire is inserted into the connecting sleeve 3 for fixation. Next, it is placed in the drill hole, so that the front side of the abutment plate 2 abuts against the outer edge of the drill hole. Then, the mounting sleeve 11, which is threaded on the outer wall of the threaded cylinder 12, is rotated. Since the mounting sleeve 11 and the threaded cylinder 12 are threadedly connected, the mounting sleeve 11 will move axially along the threaded cylinder 12 when rotated. The outer wall of the mounting sleeve 11 is rotatably connected to the ring plate 10. The axial movement of the mounting sleeve 11 will drive the ring plate 10 to move synchronously. The ring plate 10 is hinged with a hinge rod 9. The other end of the hinge rod 9 is hinged to the clamping plate 5. Therefore, the movement of the ring plate 10 will push or pull the clamping plate 5 through the hinge rod 9. Under the force of the hinge rod 9, the clamping plate 5 will slide radially along the slide rod 6 until the outer wall of the clamping plate 5 is tightly pressed against the inner wall of the mine tunnel, preventing the device from sliding due to mine tunnel vibration or water pressure impact.

[0021] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
