[0037] Reference Figure 1-11, a deep mine rock stratum movement detection device and system under wireless sensor network technology, including a pile foundation tube 1, the top of the pile foundation tube 1 is integrally formed with a top seat 11, an inner tube 2, the inner tube 2 is rotatably connected to the inside of the pile foundation tube 1, and the top of the inner tube 2 is provided with a top cover 22, an auxiliary mechanism 4, the auxiliary mechanism 4 is arranged on the surface of the top seat 11, a special-shaped workpiece 5, the special-shaped workpiece 5 is arranged inside the inner tube 2, a detection workpiece 6, the detection workpiece 6 is arranged inside the inner tube 2, a detection mechanism 7, the detection mechanism 7 is arranged on the surface of the detection workpiece 6, and a driving mechanism 3, the driving mechanism 3 is arranged on the surface of the top cover 22 and is used to drive the special-shaped workpiece 5 to move in the vertical direction. For the movement of the mine rock stratum, it is generally located on the slope of the mine, and the internal rock and soil layer moves from high to low. Therefore, it is appropriate to use a pile driver to drive the pile foundation tube 1 into a suitable position underground during use. The detection workpiece 6 is moved to an appropriate depth, and the two sides of the detection workpiece 6 are respectively directed toward the high and low sides of the rock and soil layer, and then the driving mechanism 3 is used to drive the special-shaped workpiece 5 to move, and the special-shaped workpiece 5 is used to drive the detection workpiece 6 to move, so that the detection workpiece 6 extends out of the inner tube 2 and the pile foundation tube 1, so that the monitoring mechanism in the detection workpiece 6 can be inserted into the rock layer to be monitored. When the rock layer at this position sinks, the monitoring mechanism will be used for monitoring. When the rock layer at this position is displaced, it will directly act on the surface of the detection workpiece 6, and the detection workpiece 6 is used to drive the inner tube 2 to rotate, and the inner tube 2 will drive the top cover 22 to rotate synchronously, so that real-time monitoring can be performed on the ground. At the same time, the detection workpiece 6 can be used to sample the underground rock layer soil, and the driving mechanism 3 is used to drive the special-shaped workpiece 5 to drive the detection workpiece 6 to move upward, so that the sampled rock and soil can be collected, which is convenient to operate and use, has diverse functions, and is more practical.

[0038] Furthermore, the detection workpiece 6 is set to an "L"-shaped structure, and the end of the detection workpiece 6 is set to a pointed head. The surface of the inner tube 2 is provided with a through hole 26 for the detection workpiece 6 to pass through, and the surface of the pile foundation tube 1 is provided with a movable hole 12. The detection workpiece 6 is set to a pointed head, which makes it convenient for the detection workpiece 6 to pass through the through hole 26 of the inner tube 2 and the movable hole 12 of the pile foundation tube 1, thereby being inserted into the rock and soil, wherein the size of the movable hole 12 is larger than the detection workpiece 6. When the rock and soil layer is displaced, the detection workpiece 6 can be directly pushed to make the detection workpiece 6 subject to force, and then the detection workpiece 6 drives the entire inner tube 2 to rotate a certain angle inside the pile foundation tube 1, and the inner tube 2 drives the top cover 22 to rotate synchronously, thereby facilitating the monitoring of whether the rock and soil layer is displaced.

[0039] Furthermore, an embedding groove 61 is provided on the surface of the detection workpiece 6, and a humidity sensor 66 is fixedly installed inside the embedding groove 61. The humidity sensor 66 is arranged at the position of the tip. A placement groove 65 is provided on the surface of the detection workpiece 6, and the detection mechanism 7 is arranged inside the placement groove 65. By arranging the humidity sensor 66, the humidity sensor 66 can monitor the humidity of the rock and soil layer in real time, and judge whether there is a situation where groundwater infiltration causes dilution and sinking of the rock and soil layer at this location. The humidity sensor 66 senses the humidity changes in the surrounding environment and converts these changes into electrical signals. The humidity sensor 66 usually adopts materials such as humidity sensitive resistors, and reflects the changes in humidity by measuring the changes in resistance value. The collected data is transmitted through a wireless transmission module, and the wireless transmission module uses wireless communication technology (such as ZigBee, WiFi, Bluetooth, etc.) to send the data to an external terminal device. After receiving the data, the external terminal device (such as a monitoring terminal or an environmental monitoring host) processes and stores it. The terminal device can monitor and analyze the data in real time, and send an alarm signal or execute corresponding control instructions when necessary.

[0040] Furthermore, the detection mechanism 7 includes an airbag 71 and a sealing cylinder 73. The airbag 71 is arranged inside the placement groove 65. The surface of the airbag 71 is connected with a hose 72. A through hole for the hose 72 to pass through is opened on the surface of the detection workpiece 6. The end of the hose 72 away from the airbag 71 is connected with the sealing cylinder 73. A piston 75 is arranged inside the sealing cylinder 73. A connecting rod 74 is fixedly connected to the top of the piston 75. The connecting rod 74 slides through the sealing cylinder 73. The sealing cylinder 73 is made of a transparent material and has scale lines on the surface. The airbag 71 in the detection mechanism 7 is located inside the placement groove 65 and is connected to the sealing cylinder 73 through the hose 72. When the detection workpiece 6 and the airbag 71 are inserted into the rock and soil layer, the connecting rod 74 is pressed down so that the connecting rod 74 can move. The movable piston 75 moves, thereby flushing the gas in the sealing cylinder 73 into the airbag 71. When the rock and soil layer sinks, the rock and soil layer will directly squeeze the airbag 71, so that the airbag 71 is compressed, and then the gas in the airbag 71 enters the sealing cylinder 73 through the hose 72, causing the piston 75 to move. The sinking of the internal rock and soil layer can be observed in real time using the scale lines on the sealing cylinder 73. At the same time, when it is necessary to sample and test the rock and soil layer at that location, since the airbag 71 is compressed by the rock and soil, the soil at that location can be directly dropped into the placement groove 65, and then the entire test workpiece 6 is moved into the inner cylinder 2 by the cooperation of the driving mechanism 3 and the special-shaped workpiece 5, and then it is moved up to the position of the top cover 22 to be taken out.

[0041] Furthermore, the end of the detection workpiece 6 away from the tip and the bottom end are rotatably connected with an upper roller 64 and a lower roller 63 respectively. A long groove 62 is opened at the bottom of the detection workpiece 6. The lower roller 63 is set in two groups, and the two groups of lower rollers 63 are respectively set on both sides of the long groove 62. The detection workpiece 6 is moved by squeezing the special-shaped workpiece 5. When the special-shaped workpiece 5 moves upward, the lower roller 63 of the detection workpiece 6 can be used to contact the special-shaped workpiece 5. When the special-shaped workpiece 5 moves downward, the upper roller 64 of the detection workpiece 6 can be used to contact the special-shaped workpiece 5, thereby reducing the friction between the special-shaped workpiece 5 and the detection workpiece 6, which is convenient for driving the detection workpiece 6 to move.

[0042] Furthermore, a slide bar 56 is fixedly installed on the side wall of the special-shaped workpiece 5, and the special-shaped workpiece 5 is slidably connected to the inner cylinder 2 through the slide bar 56. An opening is provided on the side of the special-shaped workpiece 5 facing the detection workpiece 6, and the top and bottom of the opening form an upper inclined surface 54 and a lower inclined surface 55 respectively. The surfaces of the upper inclined surface 54 and the lower inclined surface 55 are respectively provided with an upper slide groove 51 and a lower slide groove 57. The upper roller 64 and the lower roller 63 are respectively located inside the upper slide groove 51 and the lower slide groove 57. By providing the upper slide groove 51 and the lower slide groove 57 on the special-shaped workpiece 5, it can contact the upper roller 64 and the lower roller 63 of the detection workpiece 6, so that the movement of the detection workpiece 6 is more stable.

[0043] Furthermore, a cross bar 21 is fixedly installed inside the inner cylinder 2 at a position relative to the through hole 26, and the size of the cross bar 21 is adapted to the long slot 62. A vertical slot 52 is provided in the middle of the bottom of the special-shaped workpiece 5, and the vertical slot 52 reaches the position of the upper inclined surface 54 upward. The vertical slot 52 and the cross bar 21 are adapted in size, and an upper notch 53 is provided on the top of the special-shaped workpiece 5. By setting the cross bar 21, when the special-shaped workpiece 5 drives the detection workpiece 6 to move downward, the vertical slot 52 at the bottom of the special-shaped workpiece 5 is just located at the position of the cross bar 21, until the long slot 62 at the bottom of the detection workpiece 6 contacts the cross bar 21. At this time, the detection workpiece 6 is restricted by the cross bar 21 and cannot continue to move downward, but the special-shaped workpiece 5 continues to move downward, and in the process of moving downward During the process, the upper slide groove 51 of the upper inclined surface 54 will squeeze the upper roller 64 of the detection workpiece 6, so that the detection workpiece 6 moves on the cross bar 21 toward the position of the through hole 26 until the detection workpiece 6 passes through the through hole 26 and the movable hole 12. When it is necessary to move the detection workpiece 6 toward the inside of the inner tube 2, the special-shaped workpiece 5 is moved upward, so that the lower slide groove 57 of the lower inclined surface 55 is used to squeeze the lower roller 63 of the detection workpiece 6, and then the entire detection workpiece 6 is moved on the cross bar 21 toward the inside of the inner tube 2. By setting the upper notch 53, when the detection workpiece 6 moves toward the inner tube 2, the hose 72 is located at the position of the upper notch 53, so as to avoid the existence of the hose 72 affecting the movement of the entire detection workpiece 6.

[0044] Furthermore, the driving mechanism 3 includes a screw rod 31 and a motor 34. The motor 34 is fixedly installed at the bottom of the top cover 22. The output shaft of the motor 34 rotates and passes through the top cover 22. A driving gear 33 is fixedly installed at the output shaft port of the motor 34. The bottom end of the screw rod 31 is fixedly connected to the special-shaped workpiece 5. The screw rod 31 passes through the top cover 22. The surface of the top cover 22 is rotatably connected to the driven gear 32, and a threaded hole is provided at the center of the driven gear 32. The screw rod 31 and the driven gear 32 are threadedly connected, and the driving gear 33 and the driven gear 32 are meshed. When the driving mechanism 3 is in use, the motor 34 is started, the motor 34 drives the driving gear 33 to rotate, the driving gear 33 drives the driven gear 32 to rotate, and the driven gear 32 drives the entire screw rod 31 and the special-shaped workpiece 5 to move vertically in the inner cylinder 2.

[0045] Furthermore, the auxiliary mechanism 4 includes an annular frame 41 and a hydraulic cylinder 43. An annular groove 23 is provided at the bottom of the top cover 22. The annular frame 41 and the annular groove 23 are rotatably connected. Two hydraulic cylinders 43 are fixedly installed on the surface of the top seat 11. The output ports of the two hydraulic cylinders 43 are fixedly connected to the annular frame 41. Two vertical rods 42 are fixedly installed at the bottom of the annular frame 41. Both vertical rods 42 slide through the top seat 11. A limiting rod 24 is fixedly installed at the bottom of the top cover 22. A limiting groove 25 is provided at the top of the inner cylinder 2. When displacement occurs inside the rock and soil, the detection workpiece 6 will be squeezed. At this time, the detection workpiece 6 will drive the inner cylinder 2 to rotate. By setting the annular frame 41 and the top cover 22, the top cover 22 uses the limiting rod 24 and the limiting The groove 25 is connected to the inner cylinder 2, so when the inner cylinder 2 rotates, it will drive the top cover 22 to rotate synchronously on the annular frame 41, so as to facilitate judging whether the internal rock and soil layer is displaced by the rotation of the angle. When it is necessary to sample the rock and soil layer using the placement groove 65 of the detection workpiece 6, it is necessary to open the top cover 22. At this time, the hydraulic cylinder 43 is directly started, and the hydraulic cylinder 43 drives the annular frame 41 to move upward, and the annular frame 41 drives the top cover 22 to move upward, so as to realize the opening of the top cover 22, and facilitate the removal of the rock and soil sampled from the placement groove 65. The vertical rod 42 set can make the upward movement stability of the annular frame 41 stronger, and avoid damage to the hydraulic cylinder 43 caused by the instability caused by only connecting the hydraulic cylinder 43 with the annular frame 41.

[0046] The deep mine rock formation movement detection system includes the deep mine rock formation movement detection equipment under the above-mentioned wireless sensor network technology.

[0047] In summary, the movement of the rock strata in the mine is generally located on the slope of the mine, and the internal rock and soil layers are displaced from high to low. Therefore, during use, the pile driver is used to drive the pile foundation tube 1 into the appropriate depth at an appropriate position underground, and the two sides of the detection workpiece 6 are respectively facing the high and low sides of the rock and soil layers, and then the driving mechanism 3 is used to drive the special-shaped workpiece 5 to move, and the special-shaped workpiece 5 is used to drive the detection workpiece 6 to move, so that the detection workpiece 6 extends out of the inner tube 2 and the pile foundation tube 1, so that the monitoring mechanism in the detection workpiece 6 can be inserted into the rock stratum that needs to be monitored. When the rock stratum at this position sinks, it will be monitored by the monitoring mechanism. When the rock stratum at this position is displaced, it will directly act on the surface of the detection workpiece 6, and the detection workpiece 6 will be used to drive the inner tube 2 to rotate. The inner cylinder 2 will drive the top cover 22 to rotate synchronously, so that real-time monitoring can be carried out on the ground. At the same time, the detection workpiece 6 can be used to sample the underground rock layer soil. The driving mechanism 3 is used to drive the special-shaped workpiece 5 to drive the detection workpiece 6 to move upward, so that the sampled rock and soil can be collected. It is convenient to operate and use, has various functions, and is more practical. The detection workpiece 6 is set to a pointed head, which is convenient for the detection workpiece 6 to pass through the through hole 26 of the inner cylinder 2 and the movable hole 12 of the pile foundation cylinder 1, so as to be inserted into the rock and soil. The size of the movable hole 12 is larger than the detection workpiece 6. When the rock and soil layer is displaced, the detection workpiece 6 can be directly pushed to make the detection workpiece 6 bear force, so that the detection workpiece 6 drives the entire inner cylinder 2 to rotate at a certain angle inside the pile foundation cylinder 1, and the inner cylinder 2 The top cover 22 is driven to rotate synchronously, so as to facilitate monitoring whether the rock and soil layer is displaced. By setting a humidity sensor 66, the humidity sensor 66 can monitor the humidity of the rock and soil layer in real time to determine whether there is groundwater infiltration at this location causing the rock and soil layer to be diluted and sunk. The airbag 71 in the detection mechanism 7 is located inside the placement groove 65 and is connected to the sealing cylinder 73 through a hose 72. When the detection workpiece 6 and the airbag 71 are inserted into the rock and soil layer, the connecting rod 74 is pressed down to make the connecting rod 74 drive the piston 75 to move, thereby flushing the gas in the sealing cylinder 73 into the airbag 71. When the rock and soil layer sinks, the rock and soil layer will directly squeeze the airbag 71, so that the airbag 71 is compressed, and then the gas in the airbag 71 enters the sealing cylinder 73 through the hose 72. In the process, the piston 75 is displaced, and the sinking of the internal rock and soil layer can be observed in real time by using the scale lines on the sealing cylinder 73. At the same time, when it is necessary to sample and test the rock and soil layer at this position, since the airbag 71 is compressed by the rock and soil, the soil at this position can be directly dropped into the placement groove 65. Then, the entire test workpiece 6 is moved into the inner cylinder 2 by using the cooperation of the driving mechanism 3 and the special-shaped workpiece 5, and then it is moved up to the position of the top cover 22 to be taken out. The test workpiece 6 is moved by squeezing the special-shaped workpiece 5. When the special-shaped workpiece 5 moves upward, the lower roller 63 of the test workpiece 6 can be used to contact the special-shaped workpiece 5. When the special-shaped workpiece 5 moves downward, the upper roller 64 of the test workpiece 6 can be used to contact the special-shaped workpiece 5.Thereby reducing the friction between the special-shaped workpiece 5 and the detection workpiece 6, making it easier to drive the detection workpiece 6 to move. By providing an upper slide groove 51 and a lower slide groove 57 on the special-shaped workpiece 5, the upper roller 64 and the lower roller 63 of the detection workpiece 6 can be in contact, making the movement of the detection workpiece 6 more stable. By setting the cross bar 21, when the special-shaped workpiece 5 drives the detection workpiece 6 to move downward, the vertical groove 52 at the bottom of the special-shaped workpiece 5 is just located at the position of the cross bar 21 until the long groove 62 at the bottom of the detection workpiece 6 contacts the cross bar 21. At this time, the detection workpiece 6 is restricted by the cross bar 21 and cannot continue to move downward, but the special-shaped workpiece 5 continues to move downward. During the movement, the upper slide groove 51 of the upper inclined surface 54 squeezes the upper roller 64 of the detection workpiece 6, so that the detection workpiece 6 moves toward the position of the through hole 26 on the cross bar 21 until the detection workpiece 6 passes through the through hole 26 and the movable hole 12. When it is necessary to move the detection workpiece 6 toward the inside of the inner tube 2, the special-shaped workpiece 5 is moved upward, so that the lower slide groove 57 of the lower inclined surface 55 squeezes the lower roller 63 of the detection workpiece 6, and then the entire detection workpiece 6 moves toward the inside of the inner tube 2 on the cross bar 21. By setting the upper notch 53, when the detection workpiece 6 moves toward the inner tube 2, the hose 72 is located at the upper notch 53. 3, so as to avoid the existence of the hose 72 affecting the movement of the entire detection workpiece 6. When the driving mechanism 3 is in use, the motor 34 is started, the motor 34 drives the driving gear 33 to rotate, the driving gear 33 drives the driven gear 32 to rotate, and the driven gear 32 drives the entire screw rod 31 and the special-shaped workpiece 5 to move vertically in the inner cylinder 2. When the rock and soil are displaced inside, the detection workpiece 6 will be squeezed, and the detection workpiece 6 will drive the inner cylinder 2 to rotate. By setting the annular frame 41 and the top cover 22, the top cover 22 is connected to the inner cylinder 2 with the limiting rod 24 and the limiting groove 25, so when the inner cylinder 2 rotates, it will drive the top cover 22 to rotate in the annular frame 41 and the top cover 22. The ring frame 41 rotates synchronously, so it is convenient to judge whether the internal rock and soil layer is displaced by the rotation of the angle. When it is necessary to sample the rock and soil layer using the placement groove 65 of the detection workpiece 6, the top cover 22 needs to be opened. At this time, the hydraulic cylinder 43 is directly started, and the hydraulic cylinder 43 drives the ring frame 41 to move up, and the ring frame 41 drives the top cover 22 to move up, so as to realize the opening of the top cover 22, and it is convenient to take out the rock and soil sampled from the placement groove 65. The vertical rod 42 can make the upward movement of the ring frame 41 more stable, and avoid the damage to the hydraulic cylinder 43 caused by the instability caused by only connecting the hydraulic cylinder 43 with the ring frame 41.
