It is widely used in the dam foundation, dam shoulder, tunnel, underground power house, reservoir and slope engineering of water conservancy and hydropower projects. The main purpose of rock mass movement monitoring is to ensure the safety of buildings and rock projects through in-situ movement monitoring (excessive displacement or displacement rate is a precursor to rock mass failure), detect construction quality, and can be used to verify the correctness of the original design scheme or theoretical analysis. For underground projects, the observed surrounding rock displacement data can be used for dynamic design and information construction, and the in-situ stress field and macroscopic mechanical parameters of the rock mass can also be back-calculated.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and illustrated herein can be arranged and designed in various different configurations.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0035] It should be noted that like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it is not necessary to further define and explain it in subsequent drawings. In addition, the terms "first", "second", etc. are used only for descriptive distinction and should not be construed as indicating or implying relative importance.

[0036] The electrical components appearing in this text are all electrically connected to an external main controller and the 220V mains power supply, and the main controller can be a conventional known device such as a computer for control.

[0037] In the description of the embodiments of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "inner", "outer", "upper", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the inventive product is customarily placed during use.

[0038] Refer to Figures 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.

[0039] 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.

[0040] Further, an embedding groove 61 is formed 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 pointed position. A placement groove 65 is formed on the surface of the detection workpiece 6, and the detection mechanism 7 is arranged inside the placement groove 65. By setting 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 the rock and soil layer is diluted and subsided due to groundwater seepage. Among them, the humidity sensor 66 senses the humidity changes in the surrounding environment and converts these changes into electrical signals. The humidity sensor 66 usually uses materials such as humidity-sensitive resistors, and reflects the humidity changes by measuring the changes in resistance values. The collected data is transmitted through a wireless transmission module. The wireless transmission module uses wireless communication technologies (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.

[0041] Further, the detection mechanism 7 includes an airbag 71 and a sealing cylinder 73. The airbag 71 is arranged inside the placement groove 65. A hose 72 is communicated with the surface of the airbag 71. A through hole for the hose 72 to pass through is formed on the surface of the detection workpiece 6. One end of the hose 72 far from the airbag 71 is communicated 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 scale lines are arranged on its 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. After the detection workpiece 6 and the airbag 71 are inserted into the rock and soil layer, the connecting rod 74 is pressed down to drive the piston 75 to move, so as to inject the gas in the sealing cylinder 73 into the airbag 71. When the rock and soil layer subsides, 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 displace. The scale lines on the sealing cylinder 73 can be used to observe the subsidence of the internal rock and soil layer in real time. At the same time, when it is necessary to sample and detect 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 directly fall into the placement groove 65, and then the entire detection workpiece 6 is moved into the inner cylinder 2 by the mutual 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 take it out.

[0042] Furthermore, the upper roller 64 and the lower roller 63 are respectively rotatably connected to one end and the bottom end of the workpiece 6 away from the tip. A long groove 62 is formed in the bottom of the workpiece 6. The lower rollers 63 are provided in two groups, and the two groups of lower rollers 63 are respectively arranged on both sides of the long groove 62. The workpiece 6 is moved by the extrusion of the special-shaped workpiece 5. When the special-shaped workpiece 5 moves upward, the lower roller 63 of the 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 workpiece 6 can be used to contact the special-shaped workpiece 5, thereby reducing the friction between the special-shaped workpiece 5 and the workpiece 6 and facilitating the driving of the workpiece 6 to move.

[0043] Furthermore, a slide bar 56 is fixedly installed on the side wall of the special-shaped workpiece 5. 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 workpiece 6, and an upper inclined surface 54 and a lower inclined surface 55 are respectively formed at the top and bottom of the opening. Upper sliding grooves 51 and lower sliding grooves 57 are respectively formed on the surfaces of the upper inclined surface 54 and the lower inclined surface 55. The upper roller 64 and the lower roller 63 are respectively located inside the upper sliding groove 51 and the lower sliding groove 57. By forming the upper sliding groove 51 and the lower sliding groove 57 on the special-shaped workpiece 5, contact with the upper roller 64 and the lower roller 63 of the workpiece 6 can be achieved, making the movement of the workpiece 6 more stable.

[0044] Furthermore, a cross bar 21 is fixedly installed inside the inner cylinder 2 at a position corresponding to the through hole 26. The size of the cross bar 21 is adapted to that of the long groove 62. A vertical groove 52 is formed in the middle of the bottom of the special-shaped workpiece 5 and extends upward to the position of the upper inclined surface 54. The size of the vertical groove 52 is adapted to that of the cross bar 21. An upper notch 53 is formed in the top of the special-shaped workpiece 5. By providing the cross bar 21, when the special-shaped workpiece 5 drives the 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 workpiece 6 contacts the cross bar 21. At this time, the workpiece 6 is restricted by the cross bar 21 and cannot move downward continuously, but the special-shaped workpiece 5 continues to move downward. During the downward movement, the upper sliding groove 51 of the upper inclined surface 54 will squeeze the upper roller 64 of the workpiece 6, thereby causing the workpiece 6 to move toward the through hole 26 on the cross bar 21 until the workpiece 6 passes through the through hole 26 and the movable hole 12. When it is necessary to move the workpiece 6 toward the inside of the inner cylinder 2, the special-shaped workpiece 5 is moved upward, thereby using the lower sliding groove 57 of the lower inclined surface 55 to squeeze the lower roller 63 of the workpiece 6, and further causing the entire workpiece 6 to move toward the inside of the inner cylinder 2 on the cross bar 21. By providing the upper notch 53, when the workpiece 6 moves toward the inside of the inner cylinder 2, the hose 72 can be located at the position of the upper notch 53, avoiding the influence of the existence of the hose 72 on the movement of the entire workpiece 6.

[0045] Further, the driving mechanism 3 includes a lead screw 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 through the top cover 22. A driving gear 33 is fixedly installed at the port of the output shaft of the motor 34. The bottom end of the lead screw 31 is fixedly connected to the special-shaped workpiece 5. The lead screw 31 passes through the top cover 22. A driven gear 32 is rotatably connected to the surface of the top cover 22, and a threaded hole is provided at the central position of the driven gear 32. The lead screw 31 is threadedly connected to the driven gear 32. The driving gear 33 meshes with the driven gear 32. During the use of the driving mechanism 3, 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. The driven gear 32 drives the entire lead screw 31 and the special-shaped workpiece 5 to move vertically in the inner cylinder 2.

[0046] Further, 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 is rotatably connected to the annular groove 23. Two hydraulic cylinders 43 are fixedly installed on the surface of the top seat 11. The ports of the output ends of the two hydraulic cylinders 43 are both fixedly connected to the annular frame 41. Two vertical rods 42 are fixedly installed at the bottom of the annular frame 41. The two vertical rods 42 both 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 end of the inner cylinder 2. When the internal displacement of the rock and soil occurs, the detection workpiece 6 will be squeezed. At this time, the detection workpiece 6 will drive the inner cylinder 2 to rotate. By providing the annular frame 41 and the top cover 22, the top cover 22 is connected to the inner cylinder 2 by the limiting rod 24 and the limiting groove 25. Therefore, 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 has undergone displacement through 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. The hydraulic cylinder 43 drives the annular frame 41 to move upward. 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 inside the placement groove 65. The provided vertical rods 42 can make the upward movement of the annular frame 41 more stable, avoiding damage to the hydraulic cylinder 43 caused by the instability resulting from only connecting the hydraulic cylinder 43 to the annular frame 41.

[0047] The deep mine rock formation movement detection system includes the deep mine rock formation movement detection device under the above-mentioned wireless sensor network technology.

[0048] In summary, for the movement of mine rock strata, they are generally located on the mine slope, and the internal rock and soil layers displace from high to low. Therefore, during use, a pile driver is used to drive the pile foundation cylinder 1 into the appropriate depth at the appropriate position underground, and both sides of the detection workpiece 6 are respectively oriented towards the high and low sides of the rock and soil layers. Then, the driving mechanism 3 is used to drive the special-shaped workpiece 5 to move, and the special-shaped workpiece 5 drives the detection workpiece 6 to move, so that the detection workpiece 6 extends out of the inner cylinder 2 and the pile foundation cylinder 1, so that the monitoring mechanism in the detection workpiece 6 can be inserted into the rock strata to be monitored. When the rock strata at this position sink, the monitoring mechanism is used for monitoring. When the rock strata at this position displace, it will directly act on the surface of the detection workpiece 6, and the detection workpiece 6 drives the inner cylinder 2 to rotate. The inner cylinder 2 drives 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 strata soil. The driving mechanism 3 is used to drive the special-shaped workpiece 5 to drive the detection workpiece 6 to move upward, so as to collect the sampled rock and soil, which is convenient for operation and use, has diverse functions and stronger practicability. The detection workpiece 6 is set to be pointed, which is convenient for the detection workpiece 6 to penetrate through the through hole 26 of the inner cylinder 2 and the movable hole 12 of the pile foundation cylinder 1 and then insert into the rock and soil. The size of the movable hole 12 is larger than that of the detection workpiece 6. When the rock and soil layer displaces, it can directly push the detection workpiece 6, so that the detection workpiece 6 is stressed, and then the detection workpiece 6 drives the entire inner cylinder 2 to rotate at a certain angle inside the pile foundation cylinder 1. The inner cylinder 2 drives the top cover 22 to rotate synchronously, so as to facilitate the monitoring of whether the rock and soil layer displaces. By setting the humidity sensor 66, the humidity sensor 66 can real-time monitor the humidity of the rock and soil layer position and judge whether there is a situation where the rock and soil layer dilutes and sinks due to groundwater seepage at this position. The airbag 71 in the detection mechanism 7 is located inside the placement groove 65 and is connected through a hose 72 and a sealing cylinder 73. After 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 drives the piston 75 to move, and thus the gas in the sealing cylinder 73 is flushed 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 displace. The scale line on the sealing cylinder 73 can be used to observe the sinking situation of the internal rock and soil layer in real time. At the same time, when it is necessary to sample and detect 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 directly fall into the placement groove 65. Then, the driving mechanism 3 and the special-shaped workpiece 5 cooperate with each other to move the entire detection workpiece 6 into the inner cylinder 2, and then move it up to the position of the top cover 22 to take it out. The detection workpiece 6 realizes movement by the extrusion of 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 frictional force between the special-shaped workpiece 5 and the detection workpiece 6, facilitating the driving of the detection workpiece 6 to move. By opening an upper chute 51 and a lower chute 57 on the special-shaped workpiece 5, it can contact the upper roller 64 and the lower roller 63 of the detection workpiece 6, 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 move downward continuously, but the special-shaped workpiece 5 continues to move downward. During the downward movement, the upper chute 51 of the upper inclined surface 54 will squeeze the upper roller 64 of the detection workpiece 6, thereby causing the detection workpiece 6 to move 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 cylinder 2, the special-shaped workpiece 5 is moved upward, thereby using the lower chute 57 of the lower inclined surface 55 to squeeze the lower roller 63 of the detection workpiece 6, and then causing the entire detection workpiece 6 to move toward the inside of the inner cylinder 2 on the cross bar 21. By setting the upper notch 53, when the detection workpiece 6 moves toward the inner cylinder 2, the hose 72 is located at the position of the upper notch 53, avoiding the influence of the existence of the hose 72 on the movement of the entire detection workpiece 6. During the use of the driving mechanism 3, 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 lead screw 31 and the special-shaped workpiece 5 to move vertically in the inner cylinder 2. When displacement occurs inside the rock and soil, it will squeeze the detection workpiece 6. 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 is connected to the inner cylinder 2 through the limiting rod 24 and the limiting groove 25. Therefore, when the inner cylinder 2 rotates, it will drive the top cover 22 to rotate synchronously on the annular frame 41, facilitating the judgment of whether displacement occurs in the internal rock and soil layer through 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, 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, thereby realizing the opening of the top cover 22 and facilitating the removal of the sampled rock and soil inside the placement groove 65. The set vertical rod 42 can make the upward movement of the annular frame 41 more stable, avoiding damage to the hydraulic cylinder 43 caused by the instability resulting from only connecting the hydraulic cylinder 43 to the annular frame 41.,
