Description

Technical Field

[0001] This application relates to the field of geological monitoring technology, specifically to a microseismic rockburst monitoring sensor device. Background Technology

[0002] Microseismic rockburst refers to the dynamic phenomenon in underground engineering excavation where the accumulated elastic strain energy within the rock mass is suddenly released, causing the surrounding rock to burst and eject. This phenomenon typically occurs in rock masses under high stress or in a state of ultimate equilibrium. When disturbed by excavation activities, the strain energy stored within the rock mass is released instantaneously, causing some rock around the excavation space to protrude sharply from or eject from the parent rock mass.

[0003] In existing technologies, detection is generally carried out by drilling holes in the rock mass and embedding the detection sensor in the detection hole. However, in order to ensure the smooth installation of the detection device, the inner diameter of the detection hole is generally larger than the outer diameter of the detection device. This results in poor fit between the detection device and the rock mass, and the installation stability cannot be guaranteed. Utility Model Content

[0004] The main purpose of this application is to provide a microseismic rockburst monitoring sensor device, which aims to solve the defects of poor adhesion to rock mass in the existing technology.

[0005] This application achieves the above objectives through the following technical solutions:

[0006] A microseismic rockburst monitoring sensor device, comprising a housing;

[0007] A first expansion filling bladder is fitted onto the outer peripheral surface of the shell;

[0008] A sliding rod is slidably disposed within the housing, and a sliding plate is also slidably disposed within the housing. Along the axis of the housing, one end of the sliding rod extends outside the housing, and the other end is connected to the sliding plate.

[0009] The detection probe, with the detection sleeve mounted on the slide plate, is equipped with a second expansion filling bladder.

[0010] A pumping module is connected to the first expansion filling bladder and the second expansion filling bladder via a material delivery pipe.

[0011] Optionally, a limiting plate is also provided inside the housing, and the limiting plate is provided with a radial limiting hole adapted to the slide rod; a connecting sleeve is provided on the slide plate, and one end of the slide rod is threadedly connected to the connecting sleeve.

[0012] Optionally, the first expansion filling bladder is arranged in a ring structure, and the first expansion filling bladder is also provided with a first infusion tube for connecting the pumping module.

[0013] Optionally, along the axial direction of the housing, a first limiting ring and a second limiting ring are provided on the housing, and the first expansion filling bladder is disposed between the first limiting ring and the second limiting ring.

[0014] Optionally, the slide bar is provided with a wire hole, and a connecting wire and a second infusion tube are provided in the wire hole. The connecting wire is used to connect the detection probe and an external detection device; the second infusion tube is used to connect the second expansion filling bladder and the pumping module.

[0015] Optionally, the second expansion filling bladder is an annular structure with a plug hole adapted to the detection probe, the axial length of the plug hole being less than the length of the detection probe.

[0016] Optionally, the first expansion filling bladder and the second expansion filling bladder include an inner liner layer, the outer surface of which is wrapped with a wear-resistant layer made of wear-resistant rubber, and the wear-resistant layer is further filled with a number of nylon fibers or glass fibers.

[0017] Optionally, the slide bar is provided with a scale for indicating the insertion depth of the slide bar.

[0018] Optionally, the pumping module includes a storage tank and a delivery pump. The inlet end of the delivery pump is connected to the storage tank through an inlet pipe, and the outlet end of the delivery pump is connected to the first delivery pipe and the second delivery pipe, respectively. Both the first delivery pipe and the second delivery pipe are equipped with regulating valves.

[0019] Optionally, along the axis of the housing, one end of the housing is threadedly connected to an annular limiting block for limiting the extreme position of the slide plate, and the other end of the housing is threadedly connected to a sealing cover. The sealing cover is provided with a sliding sleeve adapted to the slide rod, and the sliding sleeve is threadedly connected to a fastening screw for fixing the slide rod.

[0020] Compared with the prior art, this application has the following beneficial effects:

[0021] This application includes a housing, on the outer peripheral surface of which a first expansion filling bladder is fitted. A slide rod and a slide plate are slidably disposed within the housing. Along the axis of the housing, one end of the slide rod extends outside the housing, and the other end is connected to the slide plate. A detection probe is also disposed on the slide plate, and a second expansion filling bladder is disposed on the detection probe. The first and second expansion filling bladders are respectively connected to a pumping module via a conveying pipe.

[0022] In use, the entire housing is inserted into the pre-drilled detection hole. When the first expansion filling bladder is fully inserted, the detection probe is adjusted to the detection position by the slide rod, and the exposed free end of the detection probe abuts against the rock mass. Then, the pumping module delivers fluids such as water or oil to the first and second expansion filling bladders respectively. The fluid fills the first and second expansion filling bladders, causing them to expand and eventually fit tightly against the inner wall of the detection hole. Since the second expansion filling bladder wraps around the detection head and the first expansion filling bladder wraps around the housing, the entire device can be stably fixed in the detection hole by the first and second expansion filling bladders, and the detection probe is tightly fitted against the rock mass. Therefore, the vibration of the rock wall can be stably transmitted to the detection probe.

[0023] Compared with the prior art, this application ensures that the entire sensing device can fit tightly with the rock mass by utilizing the expansion and flexible deformation capabilities of the first and second expansion filling bladders, thereby ensuring the structural stability of the device after installation.

[0024] Secondly, since this application can ensure stable contact between the detection probe and the rock mass, the vibration of the rock mass can be accurately obtained by the detection probe, which is beneficial to improving the accuracy of the detection parameters. Attached Figure Description

[0035] Implementation Method 1

[0036] Reference Figures 1 to 4This embodiment is an optional embodiment of this application, which discloses a microseismic rockburst monitoring and sensing device, including a housing 1, the housing 1 being cylindrical in shape and having a cavity inside.

[0037] Along the axis of the housing 1, an annular limiting block 23 is threadedly connected to one end of the housing 1, and a sealing cover 24 is threadedly connected to the other end; a sliding sleeve 25 is also provided on the sealing cover 24.

[0038] The annular limiting block 23 is installed by means of a threaded connection, which can improve the convenience of installation and also allow the position of the annular limiting block 23 to be adjusted as needed to meet different adjustment requirements; of course, the annular limiting block 23 and the housing 1 can also adopt an integral molding structure.

[0039] From the annular limiting block 23 to the sealing cover 24, a sliding plate 4 and a limiting plate 7 are sequentially arranged inside the housing 1, wherein the sliding plate 4 is slidably connected to the housing 1, and a radial limiting hole 8 is provided on the limiting plate 7. A sliding rod 3 is also provided inside the housing 1, and one end of the sliding rod 3 extends out of the housing 1 through the sliding sleeve 25 along the axial direction of the sliding rod 3; at the same time, a fastening screw 26 is threadedly connected to the sliding sleeve 25; the fastening screw 26 achieves the limiting control of the sliding rod 3 by abutting against the sliding rod 3 through its free end;

[0040] A connecting sleeve 9 is also provided on the side of the slide plate 4 opposite to the slide rod 3. The other end of the slide rod 3 passes through the radial limiting hole 8 and is threadedly connected to the connecting sleeve 9.

[0041] With the above structural design, the operator can adjust the position of the slide plate 4 arbitrarily by pushing and pulling the slide rod 3 outside the housing 1;

[0042] Furthermore, a mounting hole is provided on the side of the slide plate 4 facing the annular limiting block 23. A detection probe 5 is provided in the mounting hole, and a second expansion filling bladder 6 is sleeved on the detection probe 5. The slide rod 3 is a hollow structure with a wire hole 13. The wire hole is coaxial with the mounting hole. A connecting wire 14 and a second infusion tube 15 are provided in the wire hole 13. One end of the connecting wire 14 is electrically connected to the detection probe 5, and the other end is electrically connected to an external receiving device. The infusion tube is connected to the second expansion filling bladder 6.

[0043] The limiting plate 7 can effectively limit the swing of the slide rod 3 in the radial direction, thereby ensuring the coaxiality of the slide rod 3 and the housing 1. On the one hand, it ensures the smooth sliding of the slide rod 3 and avoids it getting stuck; on the other hand, it can ensure the positional accuracy of the detection probe 5.

[0044] Furthermore, a scale 19 is provided on the slide bar 3. The scale 19 can indicate the sliding distance of the slide plate 4 in the housing 1, thereby determining the sliding distance of the detection probe 5, realizing precise control of the position of the detection probe 5, improving the operability of the equipment, and also helping to improve the fit between the equipment and the rock wall, thereby improving the detection accuracy.

[0045] A first expansion filling bladder 2 is also provided on the outer surface of the shell 1. The first expansion filling bladder 2 is generally in the shape of a ring. The shell 1 is inserted into the central hole of the first expansion filling bladder 2 to realize the insertion connection between the shell 1 and the first expansion filling bladder 2. A first infusion tube 10 is also connected to the first expansion filling bladder 2.

[0046] The first expansion filling bladder 2 is sleeved on one end of the housing 1 where the sealing cap 24 is provided; along the axial direction of the housing 1, a first limiting ring 11 is provided on one side of the first expansion filling bladder 2, and a second limiting ring 12 is provided on the other side, that is, the first expansion filling bladder 2 is located between the first limiting ring 11 and the second limiting ring 12; the first limiting ring 11 and the housing 1 can be connected by a connecting thread or by an integral connection structure, and the second limiting ring 12 is preferably connected by a threaded connection;

[0047] The above connection method not only facilitates the installation of the first expansion filling bladder 2, but also allows for adjustment of the position of the first expansion filling bladder 2, thereby meeting different installation requirements;

[0048] Meanwhile, the clamping of the first limiting ring 11 and the second limiting ring 12 can also limit the position of the first expansion filling bag 2, preventing it from sliding axially during use, thereby ensuring its tightness in contact with the rock wall.

[0049] Furthermore, the detection sensing device also includes a pumping module, which includes a storage tank 20 and a delivery pump 21. The inlet end of the delivery pump 21 is connected to the storage tank 20 through an inlet pipe, and the outlet end of the delivery pump 21 is connected to the first delivery pipe 10 and the second delivery pipe 15, respectively. Both the first delivery pipe 10 and the second delivery pipe 15 are equipped with regulating valves 22.

[0050] In use, the on / off state of the first infusion tube 10 and the second infusion tube 15 is controlled by the regulating valve 22 to deliver fluid to the two expansion filling bladders respectively.

[0051] Furthermore, both the first expansion filling bladder 2 and the second expansion filling bladder 6 are arranged in annular structure. The second expansion filling bladder 6 has a coaxial insertion hole 16 at its center. The axial length of the insertion hole 16 is less than the length of the detection probe 5. The detection probe 5 is inserted into the insertion hole 16 and fits tightly against the inner wall of the insertion hole 16.

[0052] By controlling the length relationship as described above, the free end of the detection probe 5 is always exposed, thus ensuring close contact with the rock wall. This not only guarantees the stable installation of the detection probe 5 but also improves the accuracy of the detection.

[0053] Furthermore, both the first expansion filling bladder 2 and the second expansion filling bladder 6 include an inner liner layer. The outer surface of the inner liner layer is wrapped with a wear-resistant layer 18 made of wear-resistant rubber. The wear-resistant layer 18 is also filled with a number of nylon fibers or glass fibers. The inner liner layer is made of flexible rubber or silicone.

[0054] The above structure can ensure the flexibility of the first expansion filling bladder 2 and the second expansion filling bladder 6, while maximizing the wear resistance of the surfaces of the first expansion filling bladder 2 and the second expansion filling bladder 6 to prevent cracking during operation. At the same time, it can also appropriately increase the hardness of the first expansion filling bladder 2 and the second expansion filling bladder 6, reduce their buffering capacity, and increase the tightness of contact with the rock mass.

[0055] When using the detection sensing device described in this application, the entire housing is inserted into a pre-drilled detection hole. When the first expansion filling bladder is fully inserted, the detection probe is adjusted to the detection position by a sliding rod, and the exposed free end of the detection probe abuts against the rock mass. Then, the sliding rod is locked by a fastening screw. A pumping module delivers fluids such as water or oil to the first and second expansion filling bladders respectively. The fluid fills the first and second expansion filling bladders, causing them to expand and eventually fit tightly against the inner wall of the detection hole. Since the second expansion filling bladder wraps around the detection head, and the first expansion filling bladder wraps around the housing, the entire device can be stably fixed in the detection hole by the first and second expansion filling bladders, and the detection probe is tightly fitted against the rock mass. Therefore, the vibration of the rock wall can be stably transmitted to the detection probe.

[0056] Compared with the prior art, this application ensures that the entire sensing device can fit tightly with the rock mass by utilizing the expansion and flexible deformation capabilities of the first and second expansion filling bladders, thereby ensuring the structural stability of the device after installation.

[0057] Secondly, since this application can ensure stable contact between the detection probe and the rock mass, the vibration of the rock mass can be accurately obtained by the detection probe, which is beneficial to improving the accuracy of the detection parameters.

[0058] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
