Abstract
Description
Technical Field
[0001] This utility model relates to the field of sensor installation technology, specifically to an installation structure for a micro-vibration monitoring sensor used in mines. Background Technology
[0002] A mine shaft is the collective term for the shafts, chambers, equipment, surface buildings, and structures that form an underground coal mine production system. Sometimes, inclined shafts, vertical shafts, and adits in underground mine development are also referred to as mine shafts. Determining the size of the mining area, the mine's production capacity, and its service life is one of the key issues that must be addressed in the mine's self-design. The relationship between the mine's production capacity and its service life is essentially the relationship between the mine's production capacity and its reserves, and it directly affects the total cost per ton of coal. Within a defined mining area, with a fixed amount of reserves, a larger mine shaft results in a shorter service life, while a smaller shaft shaft results in a longer service life. A certain value between the mine's production capacity and its service life minimizes the total cost per ton of coal.
[0003] Because the previous installation process only involved drilling holes in the base plate and pouring cement, and then using bolts to install microseismic monitoring sensors on the cement, the cement caused significant energy loss during seismic wave propagation, large wave error, and the sensors were not securely fixed, making them prone to falling and being damaged. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an installation structure for a microseismic monitoring sensor in mines. This solves the problems caused by the previous installation process, which involved drilling holes in the base plate and pouring cement, then using bolts to install the microseismic monitoring sensor on the cement. These problems resulted in significant energy loss during seismic wave propagation, large standard wave errors, and the sensor being easily damaged due to insecure fixing.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a micro-vibration monitoring sensor installation structure for mines, comprising an I-beam slide rail, a first movable block connected to the top of the I-beam slide rail, a forward and reverse threaded screw threaded through one end of the first movable block, a second movable block threaded to one end of the forward and reverse threaded screw threaded through, and a third movable block threaded to one end of the forward and reverse threaded screw threaded through. The second movable block has a forward threaded groove inside, and the third movable block has a reverse threaded groove inside. A rotating disk is connected to one end of the forward and reverse threaded screw threaded through, and a handle is connected to one end of the rotating disk.
[0006] Preferably, a fixed block is connected to the bottom of the first movable block, a first groove is provided at one end of the fixed block, a telescopic rod is connected inside the first groove, a limit block is connected to one end of the telescopic rod, and a spring is wound around the outside of the telescopic rod.
[0007] Preferably, a limiting groove is provided at one end of the I-beam slide rail, and a connecting plate is connected to one end of the I-beam slide rail.
[0008] Preferably, a cylinder is connected to the top of the connecting plate, and a bolt is connected to the top of the connecting plate.
[0009] Preferably, an L-shaped plate is connected to the top of the second movable block, and a sensor body is mounted on the top of the second movable block.
[0010] Preferably, a protective cover is fitted at the top of the cylinder, a circular hole is formed at the bottom of the protective cover, and a second groove is formed at the bottom of the protective cover.
[0011] This utility model provides an installation structure for a microseismic monitoring sensor used in mines. Compared with the prior art, it has the following advantages:
[0012] 1. A micro-seismic monitoring sensor installation structure for mines, wherein the positive and negative threaded grooves inside the second and third moving blocks are arranged so that when the positive and negative threaded screws are rotated, the second and third moving blocks approach each other on the surface of the positive and negative threaded screws, or approach each other at both ends of the screws, thereby clamping the sensor body with an L-shaped plate. This avoids the problems of excessive energy loss during the transmission of seismic waves from the mine to the sensor body, resulting in large standard wave errors, and the sensor body being easily dropped and damaged due to insecure fixing.
[0013] 2. A micro-vibration monitoring sensor installation structure for mines, wherein a first moving block moves on one end surface of an I-beam slide rail, and sensors of different sizes can be clamped by the movement of the first moving block, the second moving block and the third moving block.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4 This utility model provides a technical solution: a micro-vibration monitoring sensor installation structure for mines includes an I-beam slide rail 1, a first moving block 2 connected to the top of the I-beam slide rail 1, a forward and reverse threaded screw 3 connected through one end of the first moving block 2, a second moving block 4 threadedly connected to one end of the forward and reverse threaded screw 3, a third moving block 5 threadedly connected to one end of the forward and reverse threaded screw 3, a forward threaded groove 6 opened inside the second moving block 4, a reverse threaded groove 7 opened inside the third moving block 5, a rotating disk 22 connected to one end of the forward and reverse threaded screw 3, and a handle 23 connected to one end of the rotating disk 22.
[0022] In this embodiment, when the sensor body 18 needs to be installed, the operator first places the sensor between the two sets of second moving blocks 4 and third moving blocks 5. Then, by holding the handle 23, the operator rotates the rotating disk 22, which drives the forward and reverse threaded screw 3 to rotate. Due to the forward threaded groove 6 and reverse threaded groove 7 inside the second moving blocks 4 and third moving blocks 5, when the forward and reverse threaded screw 3 is rotated, the second moving blocks 4 and third moving blocks 5 approach each other on one end surface of the forward and reverse threaded screw 3, thereby clamping the sensor body 18 with the L-shaped plate 17. This avoids the problem of excessive energy loss during the transmission of seismic waves from the mine to the sensor body 18, which leads to large standard wave errors, and the sensor body 18 being easily dropped and damaged due to insecure fixing.
[0023] Please see Figure 1-4 The bottom of the first movable block 2 is connected to a fixed block 8. One end of the fixed block 8 is provided with a first groove 9. The inside of the first groove 9 is connected to a telescopic rod 10. One end of the telescopic rod 10 is connected to a limit block 11. A spring 12 is wound around the outside of the telescopic rod 10.
[0024] When using this solution, when dealing with sensor bodies 18 of different sizes, the operator moves the limiting block 11 to disengage it from the limiting groove 13. Then, the first moving block 2 is moved to the surface of the I-beam slide rail 1. After adjusting the position of the first moving block 2, the limiting block 11 is released. Under the elastic force of the compressed spring 12, the limiting block 11 pushes itself into the limiting groove 13, thus limiting the first moving block 2 and preventing it from moving under the action of seismic waves. The extension rod 10 limits the spring 12, preventing damage to the spring 12. Then, in conjunction with the second moving block 4 and the third moving block 5, the sensor bodies 18 of different sizes are fixed.
[0025] Please see Figure 1-4 One end of the I-beam slide rail 1 has a limit groove 13, and one end of the I-beam slide rail 1 is connected to a connecting plate 14.
[0026] In this solution, the limiting groove 13 and the limiting block 11 are the same size. At the same time, multiple sets of limiting grooves 13 are opened at one end of the I-beam slide rail 1, and the connecting plate 14 is fixedly connected to the I-beam slide rail 1.
[0027] Please see Figure 1-4 A cylinder 15 is connected to the top of the connecting plate 14, and a bolt 16 is connected to the top of the connecting plate 14.
[0028] In this solution, the connecting plate 14 is fixed to the inside of the mine by bolts 16, and the cylinder 15 is fixedly connected to the connecting plate 14.
[0029] Please see Figure 1-4 The top of the second movable block 4 is connected to an L-shaped plate 17, and the top of the second movable block 4 is equipped with a sensor body 18.
[0030] During use, the sensor body 18 is clamped by the L-shaped plate 17 on the top of the two sets of second moving blocks 4 and third moving blocks 5, thereby fixing the sensor body 18.
[0031] Please see Figure 1-4 The top of the cylinder 15 is fitted with a protective cover 19, the bottom of the protective cover 19 has a round hole 20, and the bottom of the protective cover 19 has a second groove 21.
[0032] In use, the protective cover 19 is installed by aligning the round hole 20 at the bottom of the protective cover 19 with the cylinder 15 and then fitting the cylinder 15 into the round hole 20. The second groove 21 is provided so that the sensor body 18 can be protected by the protective cover 19.
[0033] In this invention, when a person skilled in the art uses this device, firstly, when faced with sensor bodies 18 of different sizes, the operator moves the limiting block 11 to disengage it from the limiting groove 13. Then, the first moving block 2 is moved to move on the surface of the I-beam slide rail 1. After adjusting the position of the first moving block 2, the limiting block 11 is released. Under the action of the spring 12 being compressed, the limiting block 11 is pushed into the limiting groove 13, thus completing the limiting of the first moving block 2. Then, by holding the handle 23, the rotating disk 22 is rotated, causing the rotating disk 22 to drive the forward and reverse threaded screw 3 to rotate. Due to the setting of the forward threaded groove 6 and the reverse threaded groove 7 inside the second moving block 4 and the third moving block 5, when the forward and reverse threaded screw 3 is rotated, the second moving block 4 and the third moving block 5 approach each other on one end surface of the forward and reverse threaded screw 3, thereby causing the L-shaped plate 17 to clamp the sensor body 18.
