[0002] In the open-pit mining environment, slope stability monitoring is a key link to ensure operational safety and prevent landslide disasters. Landslides, as a common geological disaster in open-pit mines, may not only cause significant property losses, but also pose a serious threat to the life safety of mine workers. Therefore, real-time monitoring of slope stability, predicting landslide risks, and taking timely countermeasures are important components of mine safety management.

[0003] Existing landslide monitoring devices are mostly directly inserted into the slope of open-pit mines, and trigger alarms by monitoring the contact of ore. This design is based on the principle of physical contact.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention are within the scope of protection of the present invention.

[0039] like Figure 1 and Figure 2As shown, an embodiment of the present invention provides an open-pit mine landslide monitoring device, which includes a base 10, a pressure sensor 20, a trigger part 30, a first elastic part 40, a control system 50 and an alarm part 60. The base 10 has a front side and a rear side that are relatively arranged. The base 10 has a mounting cavity 101 and a mounting port 102 that are interconnected. The mounting port 102 is located on the front side wall of the base 10; the pressure sensor 20 is arranged in the mounting cavity 101; the trigger part 30 is movably arranged in the mounting port 102 along the direction from the front side to the rear side of the base 10, and the trigger part 30 has a first trigger end and a second trigger end that are relatively arranged along the direction from the front side to the rear side of the base 10, the first trigger end is located on the outside of the base 10, and the second trigger end is located in the mounting cavity 101 and on the front side of the pressure sensor 20. The second trigger end can be in contact with or separated from the pressure sensor 20, and the pressure sensor 20 is used to sense the force of the trigger part 30; the first elastic part 40 is arranged between the base 10 and the trigger part 30, and the first elastic part 40 is used to apply a force to the trigger part 30 away from the base 10; the control system 50 is electrically connected to the pressure sensor 20, and the pressure sensor 20 transmits the sensed pressure information to the control system 50; the alarm part 60 is electrically connected to the control system 50, and the alarm part 60 is in an alarm state or a non-alarm state according to the pressure information received by the control system 50. When the pressure value detected by the pressure sensor 20 exceeds the pressure threshold F and the duration exceeds the time threshold T, the alarm part 60 is in an alarm state, otherwise the alarm part 60 is in a non-alarm state.

[0040] By applying the technical solution of the present invention, through the separate design of the trigger part 30 and the pressure sensor 20, combined with the cooperation between the control system 50 and the alarm part 60, the open-pit mine landslide monitoring device can accurately detect the magnitude of the force applied to the trigger part 30 and the action time of the force, so that only when the force reaches the dual conditions of the pressure threshold F and the time threshold T at the same time, the alarm part 60 valve will be triggered to sound an alarm, which can reduce false alarms in the process of open-pit mine landslide monitoring and improve the reliability and accuracy of the open-pit mine landslide monitoring device.

[0041] Specifically, when the open-pit mine landslide monitoring device is not subjected to external force, under the action of the first elastic part 40, the second trigger end of the trigger part 30 remains separated from the pressure sensor 20, the pressure sensor 20 does not sense pressure, and the alarm part 60 is in a non-alarm state; when a landslide occurs, the first trigger end of the trigger part 30 will be subjected to the force from the sliding ore. As the force applied to the trigger part 30 increases, the second trigger end of the trigger part 30 will gradually approach the pressure sensor 20 until it abuts against the pressure sensor 20. The pressure sensor 20 can sense the external force applied to the trigger part 30 and transmit the sensed pressure signal to the control system 50. When the pressure value sensed by the pressure sensor 20 exceeds the pressure threshold F and the duration exceeds the time threshold T, the control system 50 determines that a landslide has occurred. At this time, the alarm part 60 is triggered again, and the alarm part 60 is in an alarm state.

[0042] The pressure sensor 20 is arranged in the mounting cavity 101 of the base 10, and the trigger part 30 and the pressure sensor 20 are kept at a certain distance or in contact with each other by the first elastic part 40 when no landslide occurs, thereby protecting the pressure sensor 20 from direct impact from the outside and enhancing the stability of the open-pit mine landslide monitoring device. The force applied by the first elastic part 40 to the trigger part 30 in the direction away from the base 10 effectively reduces the situation where the trigger part 30 accidentally touches the pressure sensor 20 when there is no external pressure, reduces the risk of false alarms caused by misoperation and the like, and increases the reliability of the open-pit mine landslide monitoring device.

[0043] In the embodiment of the present solution, the control system 50 and the alarm unit 60 are installed on the top of the base 10 , and the installation cavity 101 and the installation opening 102 are arranged on the bottom of the base 10 .

[0044] In an embodiment of the present scheme, the base 10 also includes a protective net 11 and a solar panel 12. The protective net 11 is vertically installed at the center of the base 10. The protective net 11 can block gravel. The solar panel 12 is electrically connected to the alarm unit 60, the control system 50 and the pressure sensor 20 respectively. The solar panel 12 can absorb solar energy and use the converted electrical energy to power the alarm unit 60, the control system 50 and the pressure sensor 20 respectively.

[0045] Furthermore, the trigger part 30 includes a limiting structure, and the limiting structure is used to limit the movement stroke of the trigger part 30 relative to the base 10 from the rear side to the front side of the base 10. In this way, the design of the limiting structure helps to control the movement stroke of the trigger part 30 relative to the base 10, so that the movement distance of the trigger part 30 is within a certain range, so that the second trigger end of the trigger part 30 is always in the installation cavity 101 and will not be separated, thereby improving the reliability of the open-pit mine landslide monitoring device and helping to improve the sensing accuracy of the pressure sensor 20.

[0046] like Figure 1 , Figure 2 and Figure 4 As shown, specifically, the trigger part 30 includes a sliding rod 31, a limit plate 32, a trigger rod 33 and a trigger plate 34. The sliding rod 31 is movably inserted into the mounting opening 102, one end of the sliding rod 31 is located in the mounting cavity 101, and the other end is located outside the base 10; the limit plate 32 is located in the mounting cavity 101 and is fixedly connected to the sliding rod 31. When the sliding rod 31 moves toward the outside of the base 10, the limit plate 32 is limitedly matched with the inner side wall of the base 10; the trigger rod 33 is arranged on the side of the limit plate 32 away from the sliding rod 31, and the end of the trigger rod 33 away from the limit plate 32 is in contact with or separated from the pressure sensor 20; the trigger plate 34 is located on the outside of the base 10, and there is a gap between the trigger plate 34 and the base 10, and the trigger plate 34 is fixedly arranged on the end of the sliding rod 31 away from the limit plate 32.

[0047] It can be understood that, in the embodiment of the present solution, the trigger plate 34 forms a first trigger end, the trigger rod 33 forms a second trigger end, and the limit plate 32 forms a limit structure.

[0048] In an embodiment of the present scheme, an external impact force or pressure acts on the trigger plate 34. At this time, the sliding rod 31 moves from the front side to the rear side of the base 10. The sliding rod 31 drives the limit plate 32 to move. The limit plate 32 compresses the first elastic part 40, and then drives the trigger rod 33 to move toward the pressure sensor 20 until the trigger rod 33 abuts against the pressure sensor 20.

[0049] When there is no external impact force acting on the trigger plate 34, under the action of the first elastic portion 40, the side of the limit plate 32 away from the trigger rod 33 abuts against the front wall of the mounting cavity 101 of the base 10, limiting the movement of the sliding rod 31 relative to the base 10 from the rear side to the front side of the base 10, thereby realizing the limiting function.

[0050] In the embodiment of the present solution, the cross section of the trigger plate 34 is a right triangle, and the distance between the side of the trigger plate 34 away from the base 10 and the base 10 gradually decreases from bottom to top.

[0051] In the embodiment of the present scheme, two mounting openings 102 and two sliding rods 31 are provided, and the two mounting openings 102 are spaced apart along the length direction of the base 10, and the two sliding rods 31 are respectively inserted into the two mounting openings 102. In this way, the two sliding rods 31 can evenly transmit the external force exerted on the trigger plate 34 to the limit plate 32, so that the pressure sensor 20 can receive a uniform and effective pressure signal, which is helpful for accurate detection of the pressure sensor 20. At the same time, the design of the two sliding rods 31 enhances the structural stability of the trigger part 30, reduces the damage to the device caused by single-point force and other reasons, and improves the reliability of the open-pit mine landslide monitoring device.

[0052] Specifically, the first elastic portion 40 is disposed between the trigger plate 34 and the base 10 , one end of the first elastic portion 40 is connected to the base 10 , and the other end is connected to the trigger plate 34 , and the first elastic portion 40 applies a force to the trigger plate 34 away from the base 10 .

[0053] In the embodiment of the present solution, the first elastic part 40 is a spring, and two first elastic parts 40 are provided, and the two first elastic parts 40 apply a force to the trigger plate 34 away from the base 10, thereby reducing the situation where the trigger part 30 accidentally touches the pressure sensor 20. The first elastic part 40 can also reset the trigger plate 34 when it is no longer subjected to an external force, and push the trigger plate 34 to the original position when no force is applied, thereby improving the convenience and stability of operation.

[0054] Furthermore, the first elastic portion 40 is sleeved on the sliding rod 31 . Such a configuration enables the first elastic portion 40 to apply thrust to the trigger plate 34 more stably and evenly, thereby improving the movement stability of the trigger portion 30 .

[0055] like Figure 1 and Figure 3 As shown, further, the open-pit mine landslide monitoring device also includes a first plug-in portion 70, a second plug-in portion 80 and an adjusting member 90, the first plug-in portion 70 is arranged at the bottom end of the base 10, the first plug-in portion 70 extends in the vertical direction, and the first plug-in portion 70 is provided with a mutually connected avoidance cavity 701 and a avoidance hole 702, and the avoidance hole 702 extends to the outer side wall of the first plug-in portion 70 away from one end of the avoidance cavity 701; the second plug-in portion 80 is movably arranged in the avoidance cavity 701, and the second plug-in portion 80 is movably arranged in the avoidance cavity 701. The connecting part 80 has a plug-in end, and the second plug-in part 80 has an initial state and a plug-in state. When the second plug-in part 80 is in the initial state, the plug-in end is located in the avoidance hole 702 or the avoidance cavity 701, and when the second plug-in part 80 is in the plug-in state, the plug-in end extends to the outside of the first plug-in part 70 through the avoidance hole 702; the adjusting member 90 is arranged on the first plug-in part 70, and the adjusting member 90 is drivingly connected to the second plug-in part 80 so that the second plug-in part 80 can switch between the initial state and the plug-in state.

[0056] In the embodiment of the present solution, two first plug-in parts 70 are provided, and the two first plug-in parts 70 are respectively fixedly connected to the two ends of the base 10 in the length direction.

[0057] When it is necessary to fix the open-pit mine landslide monitoring device on the ground, keep the second plug-in part 80 in the initial state, insert the first plug-in part 70 downward into the ground until all the avoidance holes 702 are fully inserted into the ground, and preliminarily fix the open-pit mine landslide monitoring device; drive the second plug-in part 80 through the adjusting part 90, so that the plug-in end of the second plug-in part 80 is inserted into the ground through the avoidance hole 702 on the side wall of the first plug-in part 70. At this time, the second plug-in part 80 is in a plug-in state, and the open-pit mine landslide monitoring device is further fixed to prevent the open-pit mine landslide monitoring device from tilting during operation, thereby increasing the stability of the device.

[0058] When the open-pit mine landslide monitoring device needs to be moved, the second plug-in part 80 needs to be switched from the plug-in state to the initial state. The plug-in end of the second plug-in part 80 is retracted from the ground into the avoidance hole 702 or the avoidance cavity 701 through the adjustment part 90, so that the plug-in end of the second plug-in part 80 will not contact the ground. Then the first plug-in part 70 is pulled out of the ground to separate the open-pit mine landslide monitoring device as a whole from the ground before it is moved.

[0059] Furthermore, the second plug-in portion 80 is movably disposed in the avoidance cavity 701 along the extension direction of the avoidance hole 702, and the adjusting member 90 includes an adjusting end, which is movably disposed in the avoidance cavity 701 along the height direction, and a driving structure 100 is disposed between the adjusting end and the second plug-in portion 80, and the adjusting end drives the second plug-in portion 80 to move through the driving structure 100.

[0060] In the embodiment of the present scheme, a plurality of avoidance holes 702 are arranged at intervals along the height direction of the first plug-in portion 70. The second plug-in portion 80 includes a movable push plate 81, a reinforcement nail 82 and a limit pin 83, and the reinforcement nail 82 and the limit pin 83 are both arranged on the movable push plate 81. The limit pin 83 is arranged at the center of the movable push plate 81, and a plurality of reinforcement nails 82 are arranged, and the plurality of reinforcement nails 82 are symmetrically arranged relative to the limit pin 83 along the height direction of the movable push plate 81. Each avoidance hole 702 is correspondingly provided with a limit pin 83 or a reinforcement nail 82.

[0061] Furthermore, the extension direction of the avoidance hole 702 is perpendicular to the extension direction of the first plug-in portion 70, and the driving structure 100 includes a first inclined surface 1001 and a second inclined surface 1002, the first inclined surface 1001 is arranged on the adjustment end, and the distance between the first inclined surface 1001 and the side wall of the avoidance cavity 701 gradually increases or decreases from top to bottom; the second inclined surface 1002 is arranged on the second plug-in portion 80, the second inclined surface 1002 is adapted to the first inclined surface 1001, and the second inclined surface 1002 is abutted against the first inclined surface 1001.

[0062] Specifically, the first inclined surface 1001 and the second inclined surface 1002 of the driving structure 100 are adapted to each other. When the adjusting member 90 is driven, the first inclined surface 1001 and the second inclined surface 1002 move relative to each other, and the first inclined surface 1001 squeezes the second inclined surface 1002, so that the second plug-in portion 80 moves in the avoidance cavity 701 toward the avoidance hole 702, and the second plug-in portion 80 is switched from the initial state to the plug-in state. The matching design of the first inclined surface 1001 and the second inclined surface 1002 enables the plug-in function of the second plug-in portion 80 to be realized only through the adjusting member 90, which simplifies the operation process and improves the convenience of operation of the open-pit mine landslide monitoring device.

[0063] like Figure 3 As shown, further, the first inclined surface 1001 is a conical surface, and the second plug-in part 80 is provided with a plurality of them, and the plurality of second plug-in parts 80 are distributed at intervals along the circumference of the adjustment end. In this way, the first inclined surface 1001 adopts a conical surface design, so that when the adjustment member 90 is driven, the conical surface can form a stable contact with the second inclined surface 1002 on the second plug-in part 80, so as to achieve smooth movement of the second plug-in part 80. In addition, the circumferential distribution design of the plurality of second plug-in parts 80 enables the external impact force to be evenly dispersed, avoiding the device from being tilted or damaged due to a single point of force, and further increasing the overall stability of the device. In addition, one first plug-in portion 70 corresponds to multiple second plug-in portions 80, that is, the same first inclined surface 1001 corresponds to multiple second inclined surfaces 1002. When driven by the adjusting member 90, the moving push plates 81 of the multiple second plug-in portions 80 can be simultaneously driven to approach their corresponding avoidance holes 702, and the plug-in ends of the multiple second plug-in portions 80 can be synchronously extended out of the corresponding avoidance holes 702.

[0064] In the embodiment of this solution, the distance between the first inclined surface 1001 and the side wall of the avoidance cavity 701 gradually increases from top to bottom, and the second inclined surface 1002 is formed at the top position of the side of the movable push plate 81 facing the adjustment end.

[0065] Furthermore, a through hole 703 is further provided on the first plug-in portion 70, and the adjusting member 90 includes an adjusting screw 91, an adjusting block 92, a rotation-stopping structure 93 and a second elastic portion 94. The adjusting screw 91 extends in the vertical direction, and the adjusting screw 91 is penetrated at the through hole 703. The bottom end of the adjusting screw 91 is located in the avoidance cavity 701 and is rotatably connected to the first plug-in portion 70, and the top end of the adjusting screw 91 is located outside the first plug-in portion 70; the adjusting block 92 is sleeved on the adjusting screw 91 and is connected to the adjusting screw 91 is threadedly matched, and the adjustment block 92 forms an adjustment end; the anti-rotation structure 93 is arranged between the adjustment block 92 and the first plug-in part 70, and the anti-rotation structure 93 is anti-rotation matched with the adjustment block 92; the second elastic part 94 is arranged between the first plug-in part 70 and the second plug-in part 80, and the second elastic part 94 is used to apply a force to the second plug-in part 80 to move along the avoidance hole 702 in the direction of the avoidance cavity 701, so that the plug-in end of the second plug-in part 80 extends from the outside of the avoidance hole 702 into the avoidance hole 702.

[0066] Specifically, when the plug-in operation is performed, the top end of the adjusting screw 91 is rotated along the first direction to rotate the adjusting screw 91, and the anti-rotation structure 93 prevents the adjusting block 92 that is threadedly matched with the adjusting screw 91 from rotating, and the adjusting block 92 is restricted from moving downward. As the adjusting block 92 moves downward, under the action of the first inclined surface 1001 and the second inclined surface 1002, the movable push plate 81 of the second plug-in part 80 moves toward the side wall of the avoidance cavity 701, and the movement of the movable push plate 81 drives the reinforcement nail 82 and the limit pin 83 to extend from the corresponding avoidance hole 702.

[0067] When the first plug-in part 70 needs to be pulled out, the top end of the adjusting screw 91 is rotated in a direction opposite to the first direction to rotate the adjusting screw 91. The anti-rotation structure 93 prevents the adjusting block 92 that is threadedly matched with the adjusting screw 91 from rotating. The adjusting block 92 is restricted from moving upward, and the second elastic part 94 applies a force to the moving push plate 81 of the second plug-in part 80 away from the avoidance hole 702, so that the plug-in end of the second plug-in part 80 is gradually retracted from the ground into the avoidance hole 702 or the avoidance cavity 701.

[0068] In this solution, when the adjustment block 92 moves downward, the first inclined surface 1001 and the second inclined surface 1002 are always in contact, so that the movable push plate 81 can move in the direction close to the corresponding avoidance hole 702, and the movable push plate 81 drives the ends of the reinforcement nail 82 and the limit pin 83 to be inserted into the ground through the corresponding avoidance hole 702, so as to reinforce the open-pit mine landslide monitoring device. The second elastic part 94 is sleeved on the limit pin 83, and when the adjustment block 92 moves upward, the first inclined surface 1001 and the second inclined surface 1002 are separated, and the second elastic part 94 applies a thrust to the movable push plate 81 away from the avoidance hole 702, assisting the second plug-in part 80 to transform from the plug-in state to the initial state, and the ends of the reinforcement nail 82 and the limit pin 83 are retracted into the avoidance cavity 701 or the avoidance hole 702.

[0069] In this solution, by adjusting the threaded fit of the screw 91 and the adjusting block 92, the operator can control the rotation of the adjusting screw 91 to control the extension length of the reinforcement nail 82 and the limit pin 83 of the second plug-in part 80, so that the open-pit mine landslide monitoring device can achieve the best fixing effect under different ground conditions, and the adjustment operation is relatively simple, thereby improving the convenience of operation of the device.

[0070] In an embodiment of the present scheme, the anti-rotation structure 93 includes a plurality of sleeves which are sequentially sleeved from the inside to the outside, the top end of the sleeve located at the innermost end is fixedly connected to the top wall of the avoidance cavity 701, and the bottom end of the sleeve located at the outermost end is inserted into the interior of the adjustment block 92 and fixedly connected to the adjustment block 92. As the adjustment block 92 moves up and down, the sleeves of each layer of the anti-rotation structure 93 will also expand and contract with the adjustment block 92, so that the sleeves can always limit the adjustment block 92, so that the adjustment block 92 can only move up and down without rotating.

[0071] In the embodiment of the present scheme, a guide structure is provided between the bottom wall of the avoidance cavity 701 and the bottom of the movable push plate 81. The guide structure includes a guide block and a guide groove. The guide groove is provided on the avoidance cavity 701. The guide groove extends along the moving direction of the corresponding movable push plate 81. The guide block is fixedly mounted on the bottom end of the movable push plate 81. The shape of the guide block is adapted to the profile of the longitudinal section of the guide groove. The guide block is movably provided in the corresponding guide groove. The guide structure enables the second plug-in portion 80 to move along the extending direction of the avoidance hole 702 without tilting or the like. Moreover, the above arrangement has a simple structure and is convenient for processing the guide groove and the guide block.
