Description

Technical Field

[0001] This invention relates to the field of slope stability monitoring technology in abandoned mines, and particularly to a device and method for slope stability monitoring in abandoned mines. Background Technology

[0002] Mining involves excavating the soil, and once the ore is extracted, the mine is gradually abandoned. The mountain and soil structures of abandoned mines are damaged to varying degrees, becoming extremely fragile. Long-term exposure to rainwater can severely damage the soil ecosystem of abandoned mines, endangering their structural stability. Therefore, stability monitoring devices need to be installed on the slopes of abandoned mines to monitor their stability in real time.

[0003] Existing slope stability monitoring devices for abandoned mines typically rely on various precision instruments for close-range monitoring. However, these instruments are highly susceptible to environmental influences, with the quality of the environment significantly impacting their accuracy. Furthermore, weather conditions such as wind and rain can also affect monitoring precision. Consequently, existing slope stability monitoring devices for abandoned mines are limited in their applicability, thus reducing their overall value. Summary of the Invention

[0004] This invention discloses a slope stability monitoring device for abandoned mines, aiming to solve the problem that existing slope stability monitoring devices for abandoned mines generally rely on various precision instruments for close-range monitoring. However, these precision instruments are greatly affected by the external environment, and the quality of the external environment significantly impacts the accuracy of these instruments. Furthermore, natural weather conditions such as wind and rain also affect the monitoring accuracy, resulting in the limited applicability of existing slope stability monitoring devices for abandoned mines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A slope stability monitoring device for abandoned mines includes a fixed ring plate. A mounting rod is fixedly connected to the top of the fixed ring plate, and a lifting rod is fixedly connected to the bottom of the mounting rod near its end. A cylinder is fixedly connected to the bottom of the lifting rod. A contact monitoring component is provided at the output end of the cylinder. The contact monitoring component includes a fixed frame, which is fixedly connected to the output end of the cylinder. Two sliding grooves are opened on the top and bottom inner walls of the fixed frame. A sliding block is slidably connected inside each sliding groove. A single extrusion frame is fixedly connected to the outer side of multiple sliding blocks. A pressure sensor is fixedly connected to the inner wall of the fixed frame facing the extrusion frame. A single follower shaft is fixedly connected to the same side of the multiple sliding blocks near the outside of the fixed frame. A reversible motor is fixedly connected to one side of the follower shaft. A rotating column is fixedly connected to the output shaft of the reversible motor via a coupling. One end of the rotating column is connected to the inner wall of one side of the follower shaft via a bearing. An intermediate shaft is fixedly connected to the outer side of the rotating column. A single spin shaft is connected to the two inner walls of the intermediate shaft via bearings. A contact monitoring plate is fixedly connected to the outer side of the spin shaft.

[0007] By incorporating contact monitoring components, when monitoring the stability of abandoned mine slopes, the contact monitoring plate is placed directly on the slope. With the aid of counterweights and embedded gripping teeth, the plate maintains close contact with the soil. Changes in the contact monitoring plate indicate the stability of the abandoned mine slope. This method is intuitive and simple, eliminating the need for various precision instruments for real-time monitoring. Furthermore, the monitoring device requires no long-term maintenance, is suitable for various natural environments, has a wide range of applications, and its monitoring accuracy is not affected by environmental conditions, thus improving the accuracy of monitoring results.

[0008] In a preferred embodiment, the intermediate shaft frame is fixedly connected to the inner walls of the upper and lower ends of the contact monitoring plate with mounting brackets. Each mounting bracket has a placement slot on the side facing the contact monitoring plate. Telescopic rods are fixedly connected at equal intervals inside the placement slots. The same semi-circular pressure-bearing column is fixedly connected to the same end of multiple telescopic rods located inside the same placement slot. Pressure sensors are fixedly connected at equal intervals on the inner side of the placement slot facing the semi-circular pressure-bearing column. Embedded gripping teeth are fixedly connected at equal intervals on the bottom of the contact monitoring plate away from the mounting brackets.

[0009] In a preferred embodiment, an integrated rod is fixedly connected to the top of the intermediate shaft frame, and three mounting slots are opened on the top of the contact monitoring plate. A counterweight ball is placed inside each mounting slot, and a connecting rope is fixedly connected to the outer side of each counterweight ball at the top. The connecting rope is fixedly connected to the outer side of the integrated rod. Side rods are fixedly connected to both sides of the intermediate shaft frame, and mounting rings are fixedly connected to the outer side of the two side rods near their ends. Three embedding slots are opened on the side wall of the contact monitoring plate near the mounting rings. Two hydraulic cylinders are fixedly connected to the side of the mounting rings facing the contact monitoring plate. The output ends of the two hydraulic cylinders are fixedly connected to the same adjusting plate. A clamp is fixedly connected to the side of the adjusting plate facing each embedding slot, and the clamp is adapted to the embedding slot.

[0010] In a preferred embodiment, a lifting column is fixedly connected to the top of the fixed frame, and an outer end protection component is provided at the end of the lifting column. The outer end protection component includes a top plate, which is fixedly connected to the end of the lifting column. A buffer groove is circumferentially opened at the bottom of the top plate, and a buffer rod is slidably connected inside each buffer groove.

[0011] By incorporating external protective components, when conducting stability monitoring of abandoned mine slopes using contact monitoring components, each protective rod protects the outer side of the contact monitoring plate located above it, preventing large falling rocks from directly impacting the contact monitoring plate. Simultaneously, when falling rocks are present, they impact the buffer arc plate and slide upwards along the edge of the buffer arc plate, initially dissipating the force. Subsequently, the buffer slide bar slides in the buffer groove, and the buffer spring rod is compressed, providing secondary force dissipation. This reduces the damage caused by the rolling of falling rocks to the external protective components and extends their service life.

[0012] In a preferred embodiment, a buffer spring rod is fixedly connected to one side of the buffer slide rod, and one end of the buffer spring rod is fixedly connected to the inner wall of the buffer slide groove. A protective rod is fixedly connected to the bottom of the buffer slide rod, and a buffer arc plate is fixedly connected to the outer side of the protective rod near the bottom.

[0013] In a preferred embodiment, the outer sides of the plurality of protective rods are fixedly connected to the same annular collecting cylinder, and the annular collecting cylinder has an extraction hole on the outer side facing the contact monitoring plate. An air pump is fixedly connected to the top of the top plate, and an extraction pipe is fixedly connected to the extraction end of the air pump. The extraction pipe is inserted into the inside of the annular collecting cylinder, and an external long pipe is fixedly connected to the delivery end of the air pump. The opening end of the external long pipe is away from the contact monitoring plate.

[0014] In a preferred embodiment, the outer side of the mounting rod is provided with two docking assemblies, and the docking assemblies include an angle adjustment rail, which is fixedly connected to the top of the mounting rod. A first reversible motor is fixedly connected to the top of the mounting rod at the center point of the angle adjustment rail. The output shaft of the first reversible motor is fixedly connected to a rotating shaft through a coupling. A connecting rod is fixedly connected to the outer side of the rotating shaft. An adjusting slider is fixedly connected to the side of the connecting rod away from the first reversible motor. The adjusting slider is slidably connected to the inside of the angle adjustment rail.

[0015] In a preferred embodiment, a docking frame is fixedly connected to the outer side of the adjusting slider, and multiple compression spring rods are fixedly connected to the inner walls of both sides of the docking frame. One end of the multiple compression spring rods located on one side is fixedly connected to the same compression plate. A guide plate is fixedly connected to the top of both compression plates. Side blocks are fixedly connected to both sides of the docking frame, and hydraulic cylinders are fixedly connected to the outer sides of both side blocks. Friction plates are fixedly connected to the output ends of both hydraulic cylinders.

[0016] By incorporating a docking assembly, the monitoring device needs to be installed at equal intervals on the slope of an abandoned mine. In this invention, after installing a single monitoring device, another set of monitoring devices can be docked using the docking assembly. The corresponding docking pins are snapped into the docking frame, and the hydraulic cylinder is adjusted to drive the friction plate to clamp the docking pins. Then, the forward and reverse motors drive the docking frame to rotate, completing the angle adjustment of the docked monitoring device and enabling it to be put into use quickly.

[0017] In a preferred embodiment, the top of the fixing ring plate has an insertion hole, and an embedded screw is inserted into the insertion hole. A drill bit is fixedly connected to the bottom of the embedded screw, and a positioning sleeve is fixedly connected to the top of the embedded screw. An installation frame is distributed in a ring around the outer side of the positioning sleeve. A hydraulic cylinder is fixedly connected to the inner side of each installation frame. A clamping head is fixedly connected to the output end of each hydraulic cylinder. Embedded posts are fixedly connected at equal intervals at the bottom of the positioning sleeve. Embedded holes are opened at equal intervals at the top of the mounting ring plate, and the embedded posts are adapted to the embedded holes.

[0018] The method of using the abandoned mine slope stability monitoring device, as described above, includes the following steps:

[0019] Step 1: When monitoring the stability of an abandoned mine slope using this monitoring component, start the second forward and reverse motor. The second forward and reverse motor drives the intermediate shaft to rotate, thereby causing the contact monitoring plate to contact the soil at the slope. During the contact process, the embedded gripping teeth are embedded in the soil, and the counterweight ball further reinforces it. After the contact monitoring plate is placed, adjust the second hydraulic cylinder to drive the clamp to separate from the embedded groove, so that the contact monitoring plate and the intermediate shaft are in a separated state.

[0020] Step 2: When a landslide occurs in an abandoned mine, the contact monitoring plate slides down with the soil, and each sliding block slides in the sliding groove. The extrusion frame moves to the pressure sensor and extrudes it. Once the pressure sensor sends a signal, the back-end control terminal can quickly know that a landslide has occurred on the slope of the abandoned mine.

[0021] Step 3: When a local area of ​​the abandoned mine subsides, the contact monitoring plate rotates along with the soil, causing the contact monitoring plate to quickly come into contact with the semi-circular pressure column. An interaction force is generated between the two, and the pressure sensor 2 is squeezed. When the pressure detected by the pressure sensor reaches the specified value, the pressure sensor 2 transmits the information to the back-end control terminal, which quickly learns that the part of the abandoned mine has subsided.

[0022] As can be seen from the above, the abandoned mine slope stability monitoring device provided by the present invention has the advantages of directly placing the contact monitoring plate on the slope when monitoring the stability of abandoned mine slopes. Under the action of the counterweight ball and embedded gripping teeth, the contact monitoring plate is in close contact with the soil at the slope. The stability of the abandoned mine slope can be determined by the movement of the contact monitoring plate. It is intuitive and simple, and does not require the use of various precision instruments for real-time monitoring. In the present invention, the monitoring device does not require long-term maintenance, is suitable for various natural environments, has a wide range of applications, and its monitoring accuracy is not affected by the quality of the environment, thus improving the technical effect of improving the accuracy of monitoring results.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0036] The abandoned mine slope stability monitoring device disclosed in this invention is mainly applied to existing abandoned mine slope stability monitoring devices. In use, these devices generally rely on various precision instruments for close-range monitoring. However, these precision instruments are greatly affected by the external environment. The quality of the external environment significantly impacts the accuracy of these instruments. Furthermore, natural weather conditions such as wind and rain also affect their monitoring accuracy. Consequently, the applicable areas for existing abandoned mine slope stability monitoring devices are relatively narrow, lacking suitable scenarios.

[0037] Reference Figures 1-11 A slope stability monitoring device for abandoned mines includes a fixed ring plate 1. A mounting rod 3 is fixedly connected to the top of the fixed ring plate 1, and a hanging rod 9 is fixedly connected to the bottom of the mounting rod 3 near its end. A cylinder 8 is fixedly connected to the bottom of the hanging rod 9. A contact monitoring component 7 is provided at the output end of the cylinder 8. The contact monitoring component 7 includes a fixed frame 701, which is fixedly connected to the output end of the cylinder 8. Two sliding grooves 717 are opened on the top and bottom inner walls of the fixed frame 701. A sliding block 718 is slidably connected inside each sliding groove 717. A single extrusion frame 716 is fixedly connected to the outer side of multiple sliding blocks 718. The fixed frame 701 faces the extrusion frame 716. A pressure sensor 715 is fixedly connected to one inner wall of 16. Multiple sliding blocks 718 are fixedly connected to the same follower shaft bracket 707 on the same side near the fixed frame 701. A reversible motor 704 is fixedly connected to one side of the follower shaft bracket 707. The output shaft of the reversible motor 704 is fixedly connected to a rotating column 726 through a coupling. One end of the rotating column 726 is connected to the inner wall of one side of the follower shaft bracket 707 through a bearing. An intermediate shaft bracket 712 is fixedly connected to the outer side of the rotating column 726. The two inner walls of the intermediate shaft bracket 712 are connected to the same spin shaft 711 through bearings. A contact monitoring plate 702 is fixedly connected to the outer side of the spin shaft 711.

[0038] In specific application scenarios, when monitoring the stability of abandoned mine slopes, the contact monitoring plate 702 is placed directly on the slope. Under the action of the counterweight ball 709 and the embedded gripping teeth 703, the contact monitoring plate 702 is in close contact with the soil at the slope. The stability of the abandoned mine slope can be determined by the movement of the contact monitoring plate 702. This method is intuitive and simple, and does not require the use of various precision instruments for real-time monitoring. The monitoring device used in this invention does not require long-term maintenance, is suitable for various natural environments, has a wide range of applications, and its monitoring accuracy is not affected by the quality of the environment, thus improving the accuracy of the monitoring results.

[0039] Specifically, when monitoring the stability of an abandoned mine slope using this monitoring component, the second forward and reverse motor 704 is started. The second forward and reverse motor drives the intermediate shaft frame 712 to rotate, thereby causing the contact monitoring plate 702 to contact the soil at the slope. During the contact process, the embedded gripping teeth 703 are embedded in the soil, and the counterweight ball 709 further reinforces it. After the contact monitoring plate 702 is placed, the second hydraulic cylinder 720 is adjusted to drive the clamp 719 to separate from the embedded groove 725, so that the contact monitoring plate 702 and the intermediate shaft frame 712 are in a separated state.

[0040] It should be noted that when a landslide occurs in an abandoned mine, the contact monitoring plate 702 slides down with the soil, and each sliding block 718 slides in the sliding groove 717. The compression frame 716 moves to the pressure sensor 715 and compresses it. The pressure sensor 715 then sends a signal, and the back-end control terminal quickly learns that a landslide has occurred on the slope of the abandoned mine. When a local area of ​​the abandoned mine subsides, the contact monitoring plate 702 sinks with the soil. The contact monitoring plate 702 drives the spin shaft 711 to rotate, and the contact monitoring plate 702 quickly comes into contact with the semi-circular pressure column 723. An interaction force is generated between the two, and the pressure sensor 722 is compressed. When the pressure detected by the pressure sensor reaches a specified value, the pressure sensor 722 transmits the information to the back-end control terminal, and the back-end control terminal quickly learns that this part of the abandoned mine has subsided.

[0041] Reference Figures 1-6In a preferred embodiment, the intermediate shaft bracket 712 is fixedly connected to the inner walls of both the upper and lower ends of the contact monitoring plate 702 with mounting brackets 705. Each mounting bracket 705 has a placement slot on the side facing the contact monitoring plate 702. Telescopic rods 721 are fixedly connected at equal intervals inside the placement slots. The same end of multiple telescopic rods 721 located inside the same placement slot is fixedly connected to the same semi-circular pressure-bearing column 723. Pressure sensors 722 are fixedly connected at equal intervals on the inner side of the placement slot facing the semi-circular pressure-bearing column 723. Embedded gripping teeth 703 are fixedly connected at equal intervals at the bottom of the contact monitoring plate 702 away from the mounting brackets 705. An integrated rod 706 is fixedly connected to the top of the intermediate shaft bracket 712, and three mounting slots 724 are opened on the top of the contact monitoring plate 702. The interior of each mounting slot 724 contains a counterweight ball 709. Each counterweight ball 709 is fixedly connected to a connecting rope 708 on its top outer side. The connecting rope 708 is fixedly connected to the outer side of the integrated rod 706. Side rods 710 are fixedly connected to both sides of the intermediate shaft bracket 712. Mounting rings 713 are fixedly connected to the outer side of each side rod 710 near its end. The side wall of the contact monitoring plate 702 near the mounting rings 713 has three embedding slots 725. Two hydraulic cylinders 720 are fixedly connected to the side of the mounting rings 713 facing the contact monitoring plate 702. The output ends of the two hydraulic cylinders 720 are fixedly connected to the same adjusting plate 714. A clamp 719 is fixedly connected to the side of the adjusting plate 714 facing each embedding slot 725. The clamp 719 is adapted to the embedding slot 725.

[0042] Reference Figure 1 , Figure 2 , Figure 7 and Figure 8 In a preferred embodiment, a lifting column 5 is fixedly connected to the top of the fixed frame 701, and an outer end protection component 6 is provided at the end of the lifting column 5. The outer end protection component 6 includes a top plate 601, which is fixedly connected to the end of the lifting column 5. A buffer groove is annularly opened at the bottom of the top plate 601, and a buffer rod 609 is slidably connected inside each buffer groove. A buffer spring rod 610 is fixedly connected to one side of the buffer rod 609, and one end of the buffer spring rod 610 is fixedly connected to the inner side wall of the buffer groove. A protective rod is fixedly connected to the bottom of the buffer rod 609. 603, a buffer arc plate 602 is fixedly connected to the outer side of the guard rod 603 near the bottom. The outer side of multiple guard rods 603 is fixedly connected to the same annular collection cylinder 608. The annular collection cylinder 608 has an extraction hole 607 on the outer side facing the contact monitoring plate 702. An air pump 604 is fixedly connected to the top of the top plate 601. An extraction pipe 606 is fixedly connected to the extraction end of the air pump 604. The extraction pipe 606 is inserted into the inside of the annular collection cylinder 608. An external long pipe 605 is fixedly connected to the delivery end of the air pump 604. The opening end of the external long pipe 605 is away from the contact monitoring plate 702.

[0043] Specifically, when conducting stability monitoring at the slope of an abandoned mine using the contact monitoring component 7, each protective rod 603 protects the outer side of the contact monitoring plate 702 located above it, preventing large falling rocks from directly impacting the contact monitoring plate 702. At the same time, when falling rocks are present, they impact the buffer arc plate 602 and slide up along the edge of the buffer arc plate 602, providing initial stress relief. Subsequently, the buffer slide rod 609 slides in the buffer groove, and the buffer spring rod 610 is compressed, providing secondary stress relief and reducing the damage caused by the rolling of falling rocks to the outer protective component 6, thus extending its service life.

[0044] It should be noted that after the monitoring device has been working for a period of time, the air pump 604 is started. The air pump 604 collects small particulate impurities and dust on the outside of the contact monitoring plate 702 through the extraction holes 607 on the annular collection cylinder 608 and guides them away from the contact monitoring plate 702 to ensure the accuracy of the monitoring results of the contact monitoring plate 702.

[0045] Reference Figure 1 , Figure 2 , Figure 9 and Figure 10 In a preferred embodiment, two docking assemblies 4 are provided on the outer side of the mounting rod 3, and the docking assembly 4 includes an angle adjustment rail 401. The angle adjustment rail 401 is fixedly connected to the top of the mounting rod 3. A forward and reverse motor 403 is fixedly connected to the top of the mounting rod 3 at the center point of the angle adjustment rail 401. The output shaft of the forward and reverse motor 403 is fixedly connected to a rotating shaft 402 through a coupling. A connecting rod 404 is fixedly connected to the outer side of the rotating shaft 402. An adjusting slider 412 is fixedly connected to the side of the connecting rod 404 away from the forward and reverse motor 403. The adjusting slider 412 is slidably connected to... Inside the angle adjustment rail 401, a docking frame 405 is fixedly connected to the outer side of the adjustment slider 412, and multiple compression spring rods 410 are fixedly connected to the inner walls of both sides of the docking frame 405. One end of the multiple compression spring rods 410 on one side is fixedly connected to the same compression plate 411. A guide plate 406 is fixedly connected to the top of both compression plates 411. Side blocks 408 are fixedly connected to both sides of the docking frame 405, and hydraulic cylinders 409 are fixedly connected to the outer side of both side blocks 408. Friction plates 407 are fixedly connected to the output ends of both hydraulic cylinders 409.

[0046] Specifically, when installing the monitoring device, it needs to be installed at equal intervals on the slope of the abandoned mine. In this invention, after installing a single monitoring device, another set of monitoring devices can be connected through the docking assembly 4. The corresponding docking column is inserted into the docking frame 405, and the hydraulic cylinder 409 is adjusted to drive the friction plate 407 to clamp the docking column. Then, the forward and reverse motor drives the docking frame 405 to rotate, and the angle of the monitoring device after docking is adjusted so that it can be put into use quickly.

[0047] Reference Figure 1 , Figure 2 and Figure 11 In a preferred embodiment, the top of the fixing ring plate 1 has an insertion hole, and an embedded screw 11 is inserted into the insertion hole. A drill bit 10 is fixedly connected to the bottom of the embedded screw 11, and a positioning sleeve 2 is fixedly connected to the top of the embedded screw 11.

A clamping head 16 is fixedly connected to the output end of each hydraulic cylinder 3 15. An embedded post 12 is fixedly connected at equal intervals to the bottom of the positioning sleeve 2. An embedded hole 13 is opened at equal intervals on the top of the mounting ring 713 plate, and the embedded post 12 is adapted to the embedded hole 13.

[0048] The method of using the abandoned mine slope stability monitoring device, as described above, includes the following steps:

[0049] Step 1: When monitoring the stability of an abandoned mine slope using this monitoring component, start the second forward and reverse motor 704. The second forward and reverse motor drives the intermediate shaft frame 712 to rotate, thereby causing the contact monitoring plate 702 to contact the soil at the slope. During the contact process, the embedded gripping teeth 703 are embedded in the soil, and the counterweight ball 709 further reinforces it. After the contact monitoring plate 702 is placed, adjust the second hydraulic cylinder 720 to drive the clamp 719 to separate from the embedded groove 725, so that the contact monitoring plate 702 and the intermediate shaft frame 712 are in a separated state.

[0050] Step 2: When a landslide occurs in the abandoned mine, the contact monitoring plate 702 slides down with the soil, each sliding block 718 slides in the sliding groove 717, the squeezing frame 716 moves to the pressure sensor 715 and squeezes it, then the pressure sensor 715 sends a signal, and the background control terminal quickly learns that a landslide has occurred on the slope of the abandoned mine.

[0051] Step 3: When a local area of ​​the abandoned mine subsides, the contact monitoring plate 702 rotates along with the soil, causing the spin shaft 711 to rotate. The contact monitoring plate 702 then quickly comes into contact with the semi-circular pressure column 723, generating an interaction force between them. This causes the pressure sensor 722 to be squeezed. When the pressure detected by the pressure sensor reaches a specified value, the pressure sensor 722 transmits the information to the back-end control terminal, which quickly learns that this part of the abandoned mine has subsided.

10. A method for using an abandoned mine slope stability monitoring device, wherein the abandoned mine slope stability monitoring device as described in claim 3 is characterized in that, The method of use includes the following steps: Step 1: When monitoring the stability of the abandoned mine slope using this monitoring component, start the second forward and reverse motor (704). The second forward and reverse motor drives the intermediate shaft frame (712) to rotate, thereby driving the contact monitoring plate (702) to contact the soil at the slope. During the contact process, the embedded gripping teeth (703) are embedded in the soil, and the counterweight ball (709) further reinforces it. After the contact monitoring plate (702) is placed, adjust the second hydraulic cylinder (720) to drive the clamp (719) to separate from the embedded groove (725), so that the contact monitoring plate (702) and the intermediate shaft frame (712) are in a separated state. Step 2: When a landslide occurs in the abandoned mine, the contact monitoring plate (702) slides down with the soil, and each sliding block (718) slides in the sliding groove (717). The squeezing frame (716) moves to the pressure sensor (715) and squeezes it. Then the pressure sensor (715) sends a signal, and the background control terminal quickly learns that a landslide has occurred on the slope of the abandoned mine. Step 3: When a local area of ​​the abandoned mine subsides, the contact monitoring plate (702) rotates along with the soil as the soil subsides, causing the spin shaft (711) to rotate. The contact monitoring plate (702) then quickly comes into contact with the semi-circular pressure column (723), and an interaction force is generated between the two. The pressure sensor (722) is then squeezed. When the pressure detected by the pressure sensor reaches the specified value, the pressure sensor (722) transmits the information to the background control terminal, which quickly learns that the part of the abandoned mine has subsided.
