Description

[0001] This invention is a divisional application of "Application date: October 15, 2024; Application number: 2024114340568; Name of invention: A geological disaster monitoring system for civil aviation navigation stations". Technical Field

[0002] The present invention relates to the technical field of geological disaster monitoring equipment, and in particular to a geological disaster early warning alarm system for civil aviation navigation stations. Background Art

[0003] In recent years, geological disasters have become frequent, posing a serious threat to people's lives and property. However, existing technologies make it difficult to completely prevent these disasters. Therefore, monitoring potential geological disasters is a common approach to minimize their impact. Existing technologies typically employ geological disaster monitoring devices or systems to monitor the geological conditions in a specific area. Common geological disasters include ground subsidence, landslides, wall displacement, wall tilt, and debris flows.

[0004] However, current geological disaster monitoring devices or systems are usually expensive, and the procurement, installation, and maintenance costs of the equipment are high, making these devices difficult to apply on a large scale to ordinary houses affected by geological disasters, and are particularly unsuitable for indoor use. In addition, existing geological disaster monitoring devices or systems often require professional technicians to install and operate, which is difficult for ordinary users to master. At the same time, the high cost of use and maintenance results in the low actual popularity of existing geological disaster monitoring devices or systems, and they cannot be widely used in areas with complex geological conditions and affected by geological disasters, such as civilian houses within civil aviation navigation stations. In addition, existing geological disaster monitoring devices or systems also have the problem of single function, and are usually only used to monitor ground subsidence. For example, a ground subsidence monitoring device disclosed in Chinese patent CN 213238876 U not only has a cumbersome installation process, but also causes great damage to the ground during the installation process, making it unsuitable for indoor use. Moreover, it can only monitor whether the ground has subsided, posing a large safety risk that needs to be addressed urgently. Summary of the Invention

[0005] The first aspect of the present invention aims to solve the above technical problems and provide a geological disaster early warning alarm system that is low-cost, easy to operate, and easily popularized. The system can not only meet the needs of indoor use, but also simultaneously monitor ground subsidence, wall subsidence, wall displacement, and wall tilt, effectively avoiding casualties caused by building collapse. The main concepts are:

[0006] A geological disaster early warning alarm system for civil aviation navigation stations, comprising a power module, an alarm module and one or more monitoring devices, wherein the monitoring device comprises a wall portion and a ground portion, the wall portion comprises a detection box, a wiring module and a control module, the detection box comprises a box body and a box cover adapted to the box body, a side of the box body facing away from the box cover is constructed with a plurality of mounting holes for connecting to the wall, the bottom of the box body is constructed with a connecting port, one side of the box body is constructed with an opening, the box cover is detachably mounted on the box body and closes the opening, and the box body and the box cover together form an internal space for accommodating devices; the ground portion comprises a base for connecting to the ground and a detection component connected to the base, the base is used to support the detection component, and the base is constructed with a plurality of mounting holes; the detection component is arranged in the internal space of the box body, and the lower end of the detection component passes through the box body through the connecting port and is connected to the base below; the detection component comprises a conductive rod, a conductive upper contact portion and a conductive lower contact part, the upper contact part and the lower contact part are respectively arranged on the conductive rod, and there is a gap between the upper contact part and the lower contact part; a conductive component is arranged in the box body, the conductive component is constructed with a detection hole, the conductive rod passes through the detection hole, the upper contact part is located above the conductive component, and the lower contact part is located below the conductive component; the upper contact part and the lower contact part respectively adopt an annular structure, and the outer diameters of the upper contact part and the lower contact part are larger than the diameter of the detection hole; the power supply module is an independent module independent of the monitoring device, and the power supply module is respectively connected to the wiring module of each monitoring device for power supply; the wiring module of each monitoring device is respectively connected to the alarm module; in each monitoring device, the conductive rod is connected to the control module, and the control module and the conductive component are respectively connected to the wiring module; initially, the conductive rod does not contact the edge of the detection hole. When the conductive rod or the upper contact part or the lower contact part contacts the conductive component, the alarm module automatically alarms. In this solution, the monitoring device is constructed to include a wall part and a ground part so that the wall part and the ground part are fixed to the wall and the ground respectively. By arranging mutually cooperating detection components and conductive components in the wall part and the ground part, and configuring a conductive rod in the detection component, and configuring an upper contact part and a lower contact part spaced apart from each other on the conductive rod, at the same time, a detection hole that is simultaneously adapted to the conductive rod, the upper contact part and the lower contact part is constructed in the conductive component, and during assembly, the conductive rod is passed through the detection hole, and the upper contact part and the lower contact part are respectively located above and below the detection hole, so that the detection component and the conductive component can simultaneously form a limit fit in multiple directions and multiple angles, thereby achieving effective monitoring of geological disasters such as ground subsidence, wall subsidence, wall inclination and wall displacement, and solving the disadvantage that the existing monitoring device can only monitor ground subsidence.In this solution, the detection box and the base only need to be installed on the surface of the wall and the ground, and no pre-buried components are required. Therefore, the installation process is not likely to damage the wall and the ground, so that this system can better meet the needs of indoor installation and solve the disadvantages of the existing technology; by configuring the power module and the alarm module, and setting the monitoring device on the power supply circuit of the power module to the alarm module, during installation, it is only necessary to ensure that the detection component and the conductive component do not contact each other. During the monitoring process, as long as the detection component contacts the conductive component, the alarm module can automatically alarm, achieving the purpose of automatic alarm of geological disasters. In addition, compared with existing monitoring devices, this system can achieve the effect of automatic monitoring and early warning with a simple mechanical structure. It is not only low-cost and basically does not require subsequent maintenance, but also easy to operate. It does not require professional technicians to install and operate, and ordinary users can easily master it. This makes this system applicable to ordinary houses affected by geological disasters on a large scale, effectively solving the problem that existing geological disaster monitoring devices or systems are not widely popular and cannot be widely promoted and applied.

[0007] To quickly confirm whether each monitoring device in the system is in normal working order, the monitoring device further includes a test switch disposed within the housing. The test switch is electrically connected to the conductive rod and the conductive component via wires. During use, if the monitoring device is in normal working order, simply closing the test switch activates the alarm module, allowing for quick on-site verification of whether each monitoring device in the system is in normal working order.

[0008] Preferably, the monitoring device further comprises a mute switch arranged on the box body, the mute switch being arranged on the power supply circuit of the alarm module, and the mute switch being in a normally closed state. When mute is required, only the mute switch needs to be disconnected, which is very convenient.

[0009] Preferably, the top of the conductive rod is further threadedly connected with two nuts, the conductive sheet is clamped between the two nuts, and the wire is connected to the conductive sheet.

Initially, the lower contact portion is located at a set position away from the lower end of the sliding groove. In actual use, when the pressure between the upper contact portion and the conductive component is too large, the upper contact portion can automatically disengage from the limiting magnet and move along the sliding groove relative to the conductive rod, effectively preventing the upper contact portion and the conductive component from being crushed; at the same time, in actual use, when the pressure between the upper contact portion and the conductive component is too large, the upper contact portion can automatically disengage from the limiting magnet and move along the sliding groove relative to the conductive rod, effectively preventing the upper contact portion and the conductive component from being crushed.

[0016] Furthermore, the conductive rod is configured with a connection hole adapted for the second transmission rod, which corresponds to the strip-shaped opening. One end of the second transmission rod is rotatably connected to the connection hole, and a rubber ring is positioned between the second transmission rod and the connection hole to increase friction. The other end of the second transmission rod extends beyond the strip-shaped opening and connects to the second handle. This solution utilizes the elasticity of the rubber ring to compress the second transmission rod, achieving pre-tightening, preventing the second regulating valve from rotating under the weight of the second rack, thereby improving monitoring accuracy and reliability.

[0017] The fourth aspect of the present invention is to solve the problem of facilitating the setting of different displacement warning values ​​and tilt warning values ​​to meet the needs of more occasions. Furthermore, the monitoring device also includes a front and rear adjustment mechanism, the conductive component includes two metal parts, and the two metal parts are respectively arranged on the front and rear sides of the conductive rod; the metal part is constructed with an arc-shaped groove on the side facing the guide rod, and the arc-shaped grooves of the two metal parts correspond to each other, and the two arc-shaped grooves can together form a detection hole; the front and rear adjustment mechanism includes a first regulating valve, an adjustment block arranged on the metal part, a first rack arranged on the adjustment block, and a slide groove adapted to the metal part, the slide groove is horizontally arranged in the box body along the front and rear direction of the box body, and the two ends of the two metal parts are respectively movably constrained in the slide groove, and the slide groove is used to move the metal part along the front and rear direction. dynamic guide; the two metal parts are arranged horizontally and symmetrically; the two adjusting blocks are respectively arranged on the same side of the metal parts, and the first rack is arranged along the front and rear direction of the box body; the first regulating valve includes a first transmission rod and a first gear adapted to the first rack, the first transmission rod can be rotatably constrained to the left or right side of the box body, one end of the first transmission rod extends into the box body, the first gear is arranged at the end of the first transmission rod, the first gear is located between the two first racks, and is simultaneously engaged with the two first racks, the rotation of the first gear can drive the two metal parts to move synchronously in opposite directions, the other end of the first transmission rod extends out of the box body, and the first transmission rod is provided with a handle; the two metal parts are respectively connected to the control module or the wiring module, the upper contact part is located above the metal part, and the lower contact part is located below the metal part. In this solution, the user can drive the two metal parts to move in opposite directions synchronously by turning the first transmission rod by the handle, effectively adjusting the distance between the two metal parts along the front and rear directions of the box body, thereby achieving the purpose of adjusting the distance between the metal parts and the conductive rods along the front and rear directions of the box body. Furthermore, different displacement warning values ​​and tilt warning values ​​can be set by adjusting the initial distance between the metal parts and the conductive rods, which is very simple and convenient.

[0018] The fifth aspect of the present invention is to solve the problem that after the first use or alarm, no matter what state the detection box is in, the conductive rod can be quickly and accurately reset to the adaptive position so as to continue the detection.

The alarm module 53 is connected to the monitoring device and performs alarm and warning functions. During implementation, the location and number of the alarm modules 53 can be determined according to actual needs. The power supply module 54 is mainly used to power the various electrical components in the monitoring device and the alarm module 53 to ensure that the entire system can operate stably and reliably.

[0053] like Figure 1 and Figure 2 As shown, in this embodiment, the monitoring device includes a wall portion and a ground portion, wherein the wall portion includes a detection box 2, a wiring module, and a control module 52. The detection box 2 is configured with an internal space 21 for accommodating devices. The shape of the detection box 2 can be determined according to actual needs. For example, the detection box 2 can adopt a square structure, such as Figure 1-Figure 3As shown, the detection box 2 includes a box body 22 and a box cover 23 adapted to the box body 22. One side of the box body 22 is configured with an opening. The box cover 23 is detachably mounted on the box body 22 and closes the opening for assembly and subsequent maintenance. The box body 22 and the box cover 23 can together enclose the internal space 21. At the same time, a plurality of mounting holes 221 are configured on the side of the box body 22 facing away from the opening, such as Figure 3 As shown, the mounting hole 221 passes through the side wall of the box body 22. When in use, the box body 22 can be fixed to the wall using the fastener 13 adapted to the mounting hole 221, so that the box body 22 is connected to the wall 11, as shown in FIG. Figure 3 As shown. In practice, the fastener 13 can be a bolt or a screw. For ease of description, in this embodiment, the orientation of the box body 22 is used as a reference. The side of the box body 22 with the opening is the front side, the side facing away from the opening (i.e., the side facing the wall) is the back side, the left and right sides of the opening are the left side and the right side respectively, and the upper and lower sides of the opening are the top and the bottom respectively. Figure 3 shown.

[0054] In practice, the detection box 2 can be designed to be waterproof. For example, the box body 22 and the box cover 23 can be made of waterproof materials. A sealing component is also provided at the opening to provide waterproof and sealing protection between the box body 22 and the box cover 23.

[0055] like Figures 1-4 As shown, the ground portion includes a base 9 that can be installed on the ground and a detection component 4 connected to the base 9. The base 9 is used to support the detection component 4 and ensure the stability of the detection component 4. During implementation, the base 9 can be adhered to the ground 12 so that the base 9 is stably connected to the ground. This installation method will not cause damage to the ground and can better meet the needs of indoor installation. Of course, during implementation, the base 9 can also be detachably installed on the ground 12 by fasteners 13 for installation and removal. For example, the base 9 is constructed with multiple installation holes 221, such as Figure 1 As shown, the base 9 can be fixed to the ground by fasteners 13 such as bolts or screws adapted to the mounting holes 221 , so that the base 9 is connected to the ground.

[0056] In practice, the bottom of the box body 22 is configured with a communication port 222, such as Figure 3 As shown, the size of the communication port 222 is larger than that of the detection component 4, so that the detection component 4 can be set in the internal space 21 of the box body 22, and the lower end of the detection component 4 can pass through the box body 22 through the communication port 222 and be connected to the base 9 below. Figure 3 As shown, therefore, in implementation, the base 9 needs to be installed at the position of the communication port 222 in the adapter box body 22, that is, the installation position of the ground part should be adapted to the installation position of the wall part, as shown in FIG. Figure 1 and Figure 2 shown.

[0057] In this embodiment, the detection component 4 includes a conductive rod 41, a conductive upper contact portion 42, and a conductive lower contact portion 43. The upper contact portion 42 and the lower contact portion 43 are respectively provided on the conductive rod 41. Figure 3 As shown, the upper contact portion 42 and the lower contact portion 43 are electrically connected to the conductive rod 41 respectively; there is a gap H between the upper contact portion 42 and the lower contact portion 43, as shown in FIG. Figure 7 Correspondingly, a conductive component 3 is further provided in the box body 22, and the conductive component 3 can be fixed to the box body 22, and the conductive component 3 is located at a position that adapts to the upper contact portion 42 and the lower contact portion 43, for example, Figure 3 and Figure 7 As shown, the conductive component 3 may be disposed between the upper contact portion 42 and the lower contact portion 43 .

[0058] In this embodiment, the conductive rod 41 is connected to the control module 52, the conductive component 3 is also connected to the control module 52, and the control module 52 is connected to the corresponding alarm module 53. Figure 4 As shown. In actual application, when the wall sinks, the wall portion installed on the wall 11 sinks synchronously with the wall, and the wall portion moves downward relative to the ground portion, so that the conductive component 3 moves downward synchronously relative to the detection component 4, so that the conductive component 3 can automatically contact the lower contact portion 43, so that the conductive component 3 is electrically connected to the lower contact portion 43, and when the conductive component 3 is electrically connected to the lower contact portion 43, the alarm module 53 can automatically start and alarm, thereby achieving the purpose of wall settlement early warning. When the ground sinks, the ground portion installed on the ground sinks synchronously with the ground, and the ground portion moves downward relative to the wall portion, so that the upper contact portion 42 moves downward synchronously relative to the conductive component 3, so that the upper contact portion 42 can automatically contact the conductive component 3, so that the conductive component 3 is electrically connected to the upper contact portion 42, and when the conductive component 3 is electrically connected to the upper contact portion 42, the alarm module 53 can automatically start and alarm, thereby achieving the purpose of ground settlement early warning.

[0059] In order to synchronously monitor the wall displacement and wall inclination, in this embodiment, the conductive component 3 is further configured with a detection hole 31. The size of the detection hole 31 is larger than the size of the conductive rod 41, so that the conductive rod 41 can pass through the detection hole 31. Figure 3-Figure 5 As shown, initially, the conductive rod 41 does not contact the edge of the detection hole 31. At this time, the upper contact portion 42 is located above the conductive component 3, and the lower contact portion 43 is located below the conductive component 3. Figure 4As shown, the conductive component 3 can be horizontally arranged in the internal space 21 of the box body 22. In actual application, when the wall is displaced relative to the ground, the wall portion installed on the wall is displaced synchronously with the wall, and the wall portion moves forward and backward relative to the ground portion, causing the conductive component 3 to move forward and backward synchronously with the conductive rod 41, so that the conductive component 3 can automatically contact the conductive rod 41, thereby electrically connecting the conductive rod 41 and the conductive component 3. When the conductive rod 41 and the conductive component 3 are electrically connected, the alarm module 53 can automatically start and alarm, thereby achieving the purpose of wall displacement early warning. Because the conductive rod 41 passes through the detection hole 31 of the conductive component 3, when the wall is displaced forward and backward relative to the ground, it can also be effectively monitored by the device. When the wall is displaced left and right relative to the ground, it can also be effectively monitored by the device. Of course, in this embodiment, when the wall is displaced in other directions relative to the ground, it can also be effectively monitored by the device, thereby significantly improving the reliability of the device. In actual application, when the wall tilts relative to the ground, the wall part installed on the wall tilts synchronously with the wall, and the wall part tilts relative to the ground part, so that the conductive component 3 tilts synchronously relative to the conductive rod 41, so that the conductive component 3 can automatically contact the conductive rod 41, so that the conductive rod 41 is electrically connected with the conductive component 3. When the conductive rod 41 is electrically connected with the conductive component 3, the alarm module 53 can automatically start and alarm, thereby achieving the purpose of wall tilt warning.

[0060] In a more specific embodiment, the detection component 4 can be made of metal material as a whole. For example, the detection component 4 can be made of a stainless steel rod. In this case, the detection component 4 can be conductive as a whole. The conductive rod 41 is a part of the detection component 4. The detection component 4 can preferably be made of a round rod or a square rod, etc. In this case, the connecting port 222 is insulated to prevent the detection component 4 from conducting electricity with the box body 22. In addition, in order to improve stability and reliability during implementation, the detection component 4 can also include an insulating rod. The lower end of the conductive rod 41 is connected to the insulating rod. The insulating rod is directly or indirectly connected to the base 9 below. The insulating rod supports the conductive rod 41 and provides insulation protection for the conductive rod 41. Initially, the detection component 4 can be vertically arranged on the base 9, such as Figure 4 As shown; the conductive component 3 can adopt a plate-like structure, such as Figure 5As shown, the detection hole 31 can preferably be a round hole or a square hole. For example, in this embodiment, the conductive rod 41 is a round rod, and the detection hole 31 is also a round hole. The diameter D1 of the conductive rod 41 is smaller than the diameter D2 of the detection hole 31. The difference between the two is △D = D2-D1. △D is associated with the displacement warning value and the tilt warning value. Therefore, during implementation, the displacement warning value and the tilt warning value of the monitoring device can be effectively controlled by controlling △D during the design and processing stages. During implementation, the upper contact portion 42 and the lower contact portion 43 can each adopt an annular structure, and the outer diameter of the upper contact portion 42 and the lower contact portion 43 can be larger than the diameter of the detection hole 31.

[0061] In this embodiment, the alarm module 53 includes an alarm 531. During implementation, the alarm 531 can be set in the detection box 2 or at other locations outside the detection box 2. The alarm 531 can include a warning light, a speaker, and a combination of one or more sound and light alarms 531.

[0062] In one embodiment, the power module 54 may include a battery 542, which is used to power various electrical devices. In this case, the power module 54 may be preferably located inside the detection box 2. In another embodiment, the power module 54 may include a switching power supply 541, which is connected to a 220V mains supply to convert AC power into DC power and power various electrical devices. In this case, the power module 54 may be located inside or outside the detection box 2, and each monitoring device may share a set of power modules 54. In this embodiment, the power module 54 is an independent module independent of the monitoring device, such as Figure 4 As shown, each monitoring device is connected to the power module 54, which is helpful to simplify the system structure and reduce costs. Figure 6 As shown, the power module 54 includes a switching power supply 541 and a 12V battery 542. The 220V mains power is connected to the switching power supply 541, which is connected to the battery 542. The switching power supply 541 can convert the 220V mains power into 12V direct current. In this embodiment, the control module 52 has various implementations. For example, the control module 52 includes a relay 521 disposed in the detection box 2, such as Figure 4 and Figure 6 As shown; and to facilitate wiring operations, the wiring module includes one or more wiring terminals 51 provided on the detection box 2, and the wiring terminals 51 can be provided on the top of the box body 22, which is more convenient for wiring operations. Figure 4As shown, the terminal block 51 includes four groups of connection ports, which are, from left to right, the first group of connection ports, the second group of connection ports, the third group of connection ports, and the fourth group of connection ports. The battery 542 can be connected to the first group of connection ports and the fourth group of connection ports through two wires, respectively. The first group of connection ports and the second group of connection ports are connected to the two ports on one side of the relay 521 through two wires, respectively, and the first group of connection ports and the second group of connection ports are connected through a wire. Figure 4 As shown, the two ports on the other side of the relay 521 are connected to the conductive rod 41 and the third group of connection ports through wires; the conductive component 3 is connected to the fourth group of connection ports through wires; the alarm module 53 is connected to the third group of connection ports and the fourth group of connection ports through two wires. The specific circuit principle is as follows Figure 6 In practice, the power module 54 further includes a distribution box, and the electrical devices in the power module 54 are respectively installed in the distribution box.

[0063] During implementation, the upper contact portion 42 and the lower contact portion 43 can be welded to the conductive rod 41. In a further embodiment, the conductive rod 41 is constructed with an adjustment portion, and accordingly, the upper contact portion 42 and the lower contact portion 43 are respectively constructed with a matching portion adapted to the adjustment portion. The upper contact portion 42 and the lower contact portion 43 can be constrained to be lifted and lowered on the conductive rod 41 through the cooperation of the matching portion and the adjustment portion, so as to adjust the position of the upper contact portion 42 and the lower contact portion 43. On the one hand, it is convenient to install and disassemble, and on the other hand, it is convenient to adjust the gap H between the upper contact portion 42 and the lower contact portion 43, so as to achieve the purpose of facilitating the adjustment of the settlement warning value, so that the settlement warning value can be arbitrarily adjusted within a certain range, for example, the upper contact portion 42 and the lower contact portion 43 can be arbitrarily adjusted within the range of 1-15 mm to meet the alarm requirements of different occasions and different levels. In addition, it is convenient to adjust the positions of the upper contact part 42 and the lower contact part 43 during use, especially after the last alarm, the user can easily readjust the positions of the upper contact part 42 and the lower contact part 43 so that the system can continue to play a monitoring role, that is, after the alarm, the system can conveniently and efficiently recover from the alarm state to the monitoring state, so that the system can continue to play a monitoring role.

[0064] In practice, the adjusting portion and the matching portion have a variety of matching implementations. For example, the adjusting portion can be an external thread constructed on the conductive rod 41, and the length of the external thread can be greater than 15 mm. Figure 7 As shown, correspondingly, the mating portion is a threaded hole adapted to the external thread, and the upper contact portion 42 and the lower contact portion 43 are respectively threadedly connected to the conductive rod 41, so that the upper contact portion 42 and the lower contact portion 43 can move along the conductive rod 41 by rotating; in a specific implementation, the upper contact portion 42 and the lower contact portion 43 can use nuts.

[0065] In order to facilitate the connection of the wire, in one embodiment, the top of the conductive rod 41 is further threaded with two nuts 44, and a conductive sheet 45 is clamped between the two nuts 44. The conductive sheet 45 can be set on the conductive rod 41, and the wire is connected to the conductive sheet 45. Figure 4 and Figure 7 As shown, such a design is convenient for assembly and connection, and is also convenient for adjusting the connection position of the wire and the conductive rod 41, which is very convenient. Similarly, the conductive component 3 is also constructed with a threaded hole, and the threaded hole is threaded with a fastener 13. The fastener 13 is used to press a conductive sheet 45 against the conductive component 3, and the wire is connected to the conductive sheet 45, thereby realizing the connection between the wire and the conductive component 3, as shown in FIG. Figure 3 and Figure 4 shown.

[0066] As a usage scenario, the foundation of the living area of ​​the southeast long-range navigation station of a civil aviation airport has begun to settle since 2022, resulting in cracks up to 2 cm wide between the walls and the ground of the living area bedrooms. After professional evaluation, it was found that the foundation was relatively stable, but the cracks in the walls tended to extend and the floor inclination also increased slightly, resulting in increased risks, especially in flood seasons, with increased risks of sudden foundation collapse and house collapse. To improve safety, this monitoring system was configured in the living area. The floor plan of the living area is shown below. Figure 8 As shown, two monitoring points are selected in each of bedroom 1 and bedroom 2, and monitoring devices are set at the monitoring points respectively; at the same time, a power module 54 is set in the living room 1; an audible and visual alarm 531 is configured in the living room 2, bedroom 3 and bedroom 4 respectively, the power module 54 is connected to each monitoring device respectively, and each monitoring device is connected to each audible and visual alarm 531 respectively, and a wiring trough is installed along the wall foot for wiring, as shown in FIG. Figure 9 As shown, the sound and light alarm 531 is installed at a height of 1.8 meters above the ground. During daily operation, the monitoring device monitors foundation settlement, wall tilt, and crack changes in real time. Once the preset warning value (including settlement warning value, displacement warning value, or tilt warning value) is reached, the sound and light alarm 531 will be activated and an alarm signal will be issued to promptly alert the personnel in Living Room 2, Bedroom 3, and Bedroom 4. This can effectively reduce safety risks and effectively ensure personnel safety. In fact, within two months of installation of this system, three successful warnings have been issued.

[0067] Example 2

[0068] The main difference between this embodiment 2 and the above embodiment is that the structure of the monitoring device is different. In the monitoring system provided by this embodiment, the monitoring device further includes a front and rear adjustment mechanism 6, and the conductive component 3 includes two metal parts 61, which are respectively arranged on the front and rear sides of the conductive rod 41. Figure 10 and Figure 11As shown, the two metal pieces 61 are arranged symmetrically; in order to achieve more directional monitoring functions, in implementation, the metal piece 61 is configured with an arc-shaped groove 611 on one side facing the guide rod, as shown Figure 11 As shown, the arc-shaped grooves 611 of the two metal parts 61 correspond to each other. Figure 11 As shown, it can not only better adapt to the conductive rod 41, but also surround a larger range of the side of the conductive rod 41, thereby being more conducive to monitoring relative motion in more directions and improving the accuracy of monitoring. In implementation, the arc-shaped groove 611 is preferably constructed as a semi-circular arc-shaped groove 611, such as Figure 11 As shown, the diameter of the arc-shaped groove 611 is larger than the diameter of the conductive rod 41 , and the two arc-shaped grooves 611 can together form the detection hole 31 .

[0069] In implementation, the front-back adjustment mechanism 6 includes a first regulating valve, an adjustment block 65 provided on the metal member 61, a first rack 66 provided on the adjustment block 65, and a slide 68 adapted to the metal member 61. The slide 68 is horizontally provided in the box body 22 along the front-back direction of the box body 22, as shown in FIG. Figure 10-12 As shown, the two ends of the two metal parts 61 are movably constrained in the slide groove 68, and the slide groove 68 is used to guide the movement of the metal parts 61 in the front and rear directions. The two metal parts 61 are horizontally and symmetrically arranged, as shown in FIG. Figure 11 As shown, the metal member 61 can preferably be made of a metal plate. The two adjustment blocks 65 are respectively arranged on the same side of the metal member 61, and the two first racks 66 arranged on the two adjustment blocks 65 are respectively arranged along the front and rear directions of the box body 22. The two first racks 66 are parallel to each other and correspond to each other, as shown in FIG. Figure 10-12 The first regulating valve includes a first gear 63 adapted to the first rack 66 and a first transmission rod 62, the first transmission rod 62 is rotatably constrained to the left or right side of the box body 22, as shown. Figure 10-13 As shown, one end of the first transmission rod 62 extends into the box body 22, and the first gear 63 is provided at the end of the first transmission rod 62. The first gear 63 is located between the two first racks 66 and is engaged with the two first racks 66 at the same time. Figure 12 As shown, the other end of the first transmission rod 62 extends out of the box body 22, and the first transmission rod 62 is provided with a first handle 64. Figure 12-13 As shown, the user can rotate the first transmission rod 62 through the first handle 64, and the rotation of the first gear 63 can drive the two metal parts 61 to move synchronously in opposite directions along the front-to-back direction, effectively adjusting the distance W between the two metal parts 61 along the front-to-back direction of the box body 22, thereby achieving the purpose of adjusting the distance between the metal part 61 and the conductive rod 41 along the front-to-back direction of the box body 22, and finally achieving the purpose of adjusting the initial distance between the metal part 61 and the conductive rod 41, setting the displacement warning value and the tilt warning value.

[0070] In order to further improve the stability and reliability, in practice, the front and rear adjustment mechanism 6 further includes a horizontal bracket 69, such as Figure 10-12 As shown, the horizontal bracket 69 can be fixed in the box body 22 by the fastener 13. The upper surface of the horizontal bracket 69 is a plane. The lower surface of the metal member 61 contacts the upper surface of the horizontal bracket 69. Figure 10 As shown, the metal member 61 can move with high precision under the joint constraints of the slide 68 and the horizontal bracket 69, so that the horizontal bracket 69 can be used to further limit and constrain the metal member 61, thereby improving the stability and precision of the metal member 61 during the movement. In practice, the horizontal bracket 69 is constructed with a central hole 691 for passing the conductive rod 41, as shown in FIG. Figure 11 As shown, the diameter of the center hole 691 is larger than the outer diameter of the conductive rod 41 and can be larger than the maximum distance between the two metal parts 61 to avoid interfering with the movement and tilting of the conductive rod 41 relative to the metal parts 61. In practice, the horizontal bracket 69 can be made of a metal plate; an insulating layer is provided between the horizontal bracket 69 and the box body 22, and an insulating layer is also provided between the slide groove 68 and the box body 22. The adjustment block 65 can also preferably be a non-metallic block.

[0071] During implementation, the metal member 61 or the horizontal bracket 69 is connected to the control module 52 or the wiring module respectively, and initially, the conductive rod 41 does not contact the arc-shaped groove 611 of the metal member 61, the upper contact portion 42 is located above the metal member 61, and the lower contact portion 43 is located below the metal member 61. Figure 10 In actual applications, when the wall is displaced or tilted relative to the ground, the wall portion installed on the wall is displaced or tilted synchronously with the wall. The wall portion is displaced or tilted relative to the ground portion, causing the metal member 61 to move back and forth or tilt synchronously relative to the conductive rod 41, so that the metal member 61 can automatically contact the conductive rod 41, so that the conductive rod 41 and the metal member 61 are electrically connected. When the conductive rod 41 and the metal member 61 are electrically connected, the alarm module 53 can automatically start and alarm, thereby achieving the purpose of early warning of wall displacement and tilt. The design in this embodiment, on the one hand, makes the distance between the metal part 61 and the conductive rod 41 adjustable, so that the user can set the initial displacement warning value and tilt warning value according to actual needs, which can meet the needs of different occasions and significantly improve the versatility of the system; on the other hand, after the last alarm, the user can easily readjust the position of the metal part 61 through the first regulating valve, so that the system can continue to play a monitoring role, that is, after the alarm, the system can conveniently and efficiently restore from the alarm state to the initial monitoring state, so that the system can continue to play a monitoring role, and the warning value during continued monitoring can also be adjusted according to actual needs to achieve the purpose of reuse, thereby effectively solving the problem that existing equipment cannot or is not convenient to be reused.

[0072] In a more complete solution, one of the adjustment blocks 65 is further provided with a constraint block 67 for constraining the first rack 66, such as Figure 12 As shown, the first rack 66 passes through the constraint block 67 to prevent the first rack 66 from shaking up and down, thereby improving the meshing accuracy of the first rack 66 and the first gear 63. In order to facilitate user adjustment, a first scale 223 is also provided on the left or right side of the box body 22, as shown in FIG. Figure 13 As shown, the first scale 223 is arranged along the circumferential direction of the first gear 63. Accordingly, the first regulating valve also includes an indicator portion adapted to the first scale 223. The indicator portion can be a pointer so that the current displacement warning value or tilt warning value can be indicated through the cooperation of the indicator portion and the first scale 223, thereby making it easier for the user to make adjustments quickly and accurately.

[0073] Example 3

[0074] The main difference between this embodiment 3 and the above embodiment 2 is the different structure of the monitoring device. In the monitoring system provided in this embodiment, the monitoring device further includes an up-down adjustment mechanism 7, which includes a second regulating valve, two guide grooves 411 constructed on the conductive rod 41, and two second racks 71 adapted to the guide grooves 411. The guide grooves 411 are symmetrically arranged along the length direction of the conductive rod 41, as shown in FIG. Figure 14-16 As shown, the two guide grooves 411 are connected to each other, and the conductive rod 41 is also configured with a strip-shaped opening 412. Figure 14 As shown, the strip-shaped opening 412 is arranged along the length direction of the conductive rod 41, and the strip-shaped opening 412 is connected to the two guide grooves 411; the second rack 71 is movably constrained in the guide groove 411, so that the second rack 71 and the conductive rod 41 form a moving pair, and the two second racks 71 are arranged relative to each other, as shown in FIG. Figure 15 and Figure 16 As shown, the upper contact portion 42 and the lower contact portion 43 are respectively provided on two connecting members 72, and the two connecting members 72 are respectively connected to the two second racks 71 via the strip-shaped openings 412. Figure 17 As shown, the second regulating valve includes a second transmission rod 73, a second gear 74 provided on the second transmission rod 73, and a second handle 75 connected to the second transmission rod 73. The second transmission rod 73 is rotatably constrained to the conductive rod 41, and the second gear 74 is exactly located between the two second racks 71, as shown in FIG. Figure 15 As shown, a connecting hole 413 adapted to the second transmission rod 73 is constructed between the two guide grooves 411. The connecting hole 413 corresponds to the strip-shaped opening 412. One end of the second transmission rod 73 is rotatably connected to the connecting hole 413. The other end of the second transmission rod 73 extends out of the strip-shaped opening 412 and is connected to the second handle 75. Figure 15To prevent the second regulating valve from rotating automatically under the gravity of the second rack 71, in one embodiment, a rubber ring 76 for increasing friction is provided between the second transmission rod 73 and the connecting hole 413. Figure 15 As shown, the rubber ring 76 can be bonded into the connecting hole 413, and the elasticity of the rubber ring 76 can be used to press the second transmission rod 73 to achieve the purpose of pre-tightening, thereby preventing the second regulating valve from rotating automatically under the gravity of the second rack 71. Figure 15 As shown, the second gear 74 is respectively engaged with the two second racks 71; when in use, the two second racks 71 can be driven to move synchronously in the opposite direction by rotating the second handle 75, thereby driving the upper contact portion 42 and the lower contact portion 43 to move synchronously in the opposite direction along the length direction of the conductive rod 41. This design, on the one hand, makes the spacing between the upper contact portion 42 and the lower contact portion 43 adjustable, so that the user can set the initial settlement warning value according to actual needs, which can meet the needs of different occasions and significantly improve the versatility of the system; on the other hand, after the last alarm, the user can easily readjust the position of the upper contact portion 42 and the lower contact portion 43 through the second regulating valve, so that the system can continue to play a monitoring role, that is, after the alarm, the system can conveniently and efficiently restore from the alarm state to the initial monitoring state, so that the system can continue to play a monitoring role, and the warning value during continued monitoring can also be adjusted according to actual needs to achieve the purpose of reuse, thereby effectively solving the problem that the existing equipment cannot or is not convenient to be reused.

[0075] It is understood that, in practice, the upper contact portion 42 and the lower contact portion 43 can be symmetrically mounted above and below the conductive component 3, so that initially, the distance between the upper contact portion 42 and the conductive component 3 is equal to the distance between the lower contact portion 43 and the conductive component 3. In practice, the upper contact portion 42 and the lower contact portion 43 are preferably configured to surround the conductive rod 41, such as Figure 16 As shown, so as to better cooperate with the conductive component 3.

[0076] In order to facilitate user adjustment, in a more complete solution, the conductive rod 41 is further provided with a second scale 414, such as Figure 17 As shown, the second scale 414 is arranged along the circumferential direction of the second gear 74, and the second regulating valve also includes an indicator portion adapted to the second scale 414, so that the current settlement warning value can be indicated through the cooperation of the indicator portion and the second scale 414, thereby making it easier for the user to make adjustments quickly and accurately.

[0077] In order to facilitate the user to use the system, in a more complete solution, the conductive rod 41 is further provided with a bull's-eye displacement disk 46. The bull's-eye displacement disk 46 can be preferably arranged at the top of the conductive rod 41, such as Figure 17As shown, a cross bull's eye and concentric circle marks are provided on the bull's eye displacement disk 46. Accordingly, an observation window 231 is provided on the box cover 23. The observation window 231 faces the bull's eye displacement disk 46. Transparent organic glass is installed in the observation window 231. Figure 18 As shown, a transparent cross scale is attached to the organic glass. Initially, the center of the bull's eye displacement disk 46 coincides with the center of the cross scale. This not only makes it easier for the user to adjust the device, but also, when in use, by reading the displacement value of the bull's eye on the detection device, the movement status of the monitored object can be calculated regardless of whether the monitoring system has activated an alarm, which is very convenient for on-site personnel to understand changes in geological conditions.

[0078] Example 4

[0079] In order to solve the problem of rapid and accurate reset of the conductive rod 41 during use and debugging for reuse, the main difference between this embodiment 4 and the above-mentioned embodiment 3 is that, in the monitoring system provided by this embodiment, the monitoring device further includes two sets of self-positioning mechanisms 8 spaced apart along the height direction of the box body 22, the self-positioning mechanism 8 including a positioning block 81, an insulating sleeve 82 and three springs 83, the positioning block 81 being fixed in the box body 22, and the three positioning blocks 81 being cocircular, as shown in FIG. Figure 19 and 20 As shown, the centers of the three positioning blocks 81 are consistent with the centers of the detection hole 31 and the communication port 222; the insulating sleeve 82 is provided on the conductive rod 41, and the upper contact portion 42 and the lower contact portion 43 are located between the two insulating sleeves 82, as shown in FIG. Figure 19 One end of each spring 83 is connected to the insulating sleeve 82, and the other end is connected to the positioning block 81. The three springs 83 are arranged 120 degrees from each other. The three springs 83 are the same as Figure 20 As shown, the three springs 83 are all tension springs 83, and the three springs 83 are all in a tensioned state. The tension of the spring 83 can be much greater than the deadweight of the conductive rod 41, which greatly reduces the influence of the deadweight of the conductive rod 41 on the self-positioning, so that when the box body 22 is in any state, the conductive rod 41 can automatically be in the center position of the three positioning blocks 81 under the elastic force of the three springs 83; and through the cooperation of the two sets of self-positioning mechanisms 8, no matter whether the box body 22 is in a vertical state or a tilted state, it can be ensured that the center of the conductive rod 41 is consistent with the center of the detection hole 31 and the center of the connecting port 222.

[0080] In practice, each spring 83 can be arranged horizontally, but in a preferred embodiment, in the self-positioning mechanism 8 located above, the insulating sleeve 82 can be arranged above the positioning block 81, so that the spring 83 is arranged obliquely, such as Figure 19 As shown, at the same time, in the self-positioning mechanism 8 located below, the insulating sleeve 82 can be arranged below the positioning block 81, so that the spring 83 is arranged obliquely, as shown in FIG. Figure 19 As shown, through the cooperation of the two sets of self-positioning mechanisms 8, no matter the box body 22 is in a vertical state or an inclined state, it can be ensured that the conductive component 3 is exactly located between the upper contact portion 42 and the lower contact portion 43.

[0081] In order to facilitate quick reset, in this embodiment, the base 9 includes a fixed seat 91 and a movable seat 92. Figure 21 and 22 As shown, when in use, the fixed base 91 is fixedly mounted on the ground 12. For example, the mounting hole 221 can be constructed on the fixed base 91, and the movable base 92 can be detachably mounted on the fixed base 91, and the position of the movable base 92 is adjustable. For example, in one embodiment, the fixed base 91 is further configured with a plurality of mutually parallel first holes 911, and correspondingly, the movable base 92 is provided with two arc-shaped second holes 921, and the second holes 921 are symmetrically arranged, as shown in FIG. Figure 21 As shown, the movable seat 92 can not only be fixed to the fixed seat 91 by means of a fastener 13 (such as a bolt pair) adapted to the first hole 911 and the second hole 921, but also the movable seat 92 can be fixed at any position of the fixed seat 91, and the movable seat 92 can also be rotated relative to the fixed seat 91 by a desired angle so as to better meet the fixing requirements of the conductive rod 41 at different positions and orientations.

[0082] At the same time, if Figure 22-Figure 24 As shown, the detection component 4 also includes a fixing frame 47 and a connecting frame 48. The fixing frame 47 is fixedly connected to the movable seat 92. The upper end of the fixing frame 47 is configured with a first adjustment hole, and the lower end of the connecting frame 48 is configured with a second adjustment hole. The connecting frame 48 is fixed to the fixing frame 47 by a fastener 13 adapted to the first adjustment hole and the second adjustment hole. When the fastener 13 is loosened, the connecting frame 48 can rotate relative to the fixing frame 47 to adjust the angle between the connecting frame 48 and the fixing frame 47 as needed. After the adjustment is in place, it can be locked with the fastener 13. Figure 24 As shown, the upper end of the connecting frame 48 is constructed with two third holes 481 parallel to each other, and the length direction of the third holes 481 is parallel to the central axis direction of the second adjustment hole, so as to increase the degree of freedom of adjustment. Correspondingly, the lower end of the conductive rod 41 is constructed with a fourth hole 415 arranged along its length direction, as shown in FIG. Figure 24As shown, during assembly, the conductive rod 41 can be securely fixed to the connecting frame 48 using fasteners 13 such as a bolt pair that fits in the third hole 481 and the fourth hole 415. With this design, it is possible to adjust the position of the third hole 481 relative to the fixing base 91, adjust the orientation of the third hole 481 relative to the fixing base 91, and adjust the inclination angle of the third hole 481 relative to the fixing base 91, thereby adapting to any inclination angle (including front-to-back inclination and left-to-right inclination) and any position of the conductive rod 41. When in use, after the conductive rod 41 automatically moves to the adapted position under the action of the self-positioning mechanism 8, the third hole 481 can always be adjusted to a position that fits the fourth hole 415, so as to securely fix the conductive rod 41 and allow the monitoring device to continue to be used.

[0083] When using the monitoring device, for example, during initial setting or when resetting the setting after an alarm, the user can first disconnect the conductive rod 41 from the connecting frame 48 (for example, by removing the fastener 13, which is equivalent to unlocking the conductive rod 41). Figure 24 As shown, the conductive rod 41 can be automatically positioned to a position consistent with the center of the detection hole 31 and the center of the communication port 222 under the action of the self-positioning mechanism 8, and can be confirmed through the observation window 231; then adjust the movable seat 92 or the connecting frame 48 so that the third hole 481 on the connecting frame 48 is adapted to the fourth hole 415 at the lower end of the conductive rod 41; then use the fastener 13 to fix the movable seat 92 to the fixed seat 91, and use the fastener 13 to fix the conductive rod 41 to the connecting frame 48, as shown. Figure 23 or Figure 25 As shown, the conductive rod 41 is firmly fixed, so that during subsequent use, the conductive rod 41 will not move under the action of the spring 83. At this time, the conductive rod 41 is at the center of the detection hole 31, and the conductive component 3 is also at a position between the upper contact portion 42 and the lower contact portion 43; then, the user can set the settlement warning value through the first regulating valve, and can set the displacement warning value or the tilt warning value through the second regulating valve, so that the initial setting of the monitoring device or the resetting setting after the alarm can be completed very conveniently and efficiently, so that the system can continue to perform monitoring work, which is particularly suitable for occasions where the wall and the ground are not perpendicular.

[0084] Example 5

[0085] In order to solve the problem of quickly confirming whether each monitoring device in the system is in normal working condition, the main difference between this embodiment 5 and the above embodiment 4 is that, in the monitoring system provided by this embodiment, the monitoring device further includes a test switch 24 provided in the box body 22, such as Figure 26As shown, the test switch 24 is electrically connected to the conductive rod 41 and the conductive component 3 via wires. During use, if the monitoring device is in normal working condition, simply closing the test switch 24 can activate the alarm module 53, thereby quickly determining on site whether each monitoring device in the system is in normal working condition.

[0086] In a more complete solution, the monitoring device further includes a mute switch 25 provided on the box body 22, such as Figure 26 As shown, the mute switch 25 is provided on the power supply circuit of the alarm module 53, and the mute switch 25 is in a normally closed state. When silencing is required, it is only necessary to disconnect the mute switch 25, which is very convenient.

[0087] Example 6

[0088] On the basis of the above embodiments, in order to solve the problem that the actual settlement or displacement on site is too large, resulting in the upper contact portion 42 or the lower contact portion 43 or the conductive component 3 being crushed and unable to continue to be used, in this embodiment, the connecting piece 72 for connecting the upper contact portion 42 is constructed with a sliding groove 721 arranged along the length direction of the conductive rod 41, and a limiting magnet 722 is provided at the lower end of the sliding groove 721, as shown in FIG. Figure 27 As shown, accordingly, the upper contact portion 42 is provided with a sliding block 421 adapted to the sliding groove 721. The sliding block 421 is constrained in the sliding groove 721 and can slide along the sliding groove 721. Since the upper contact portion 42 is made of a conductive metal material, initially, the upper contact portion 42 can be adsorbed on the limiting magnet 722 under the action of its own gravity and the magnetic force of the limiting magnet 722. The limiting magnet 722 supports the upper contact portion 42. Figure 27 As shown, in actual use, when the pressure between the upper contact portion 42 and the conductive component 3 is too great, the upper contact portion 42 can automatically disengage from the limiting magnet 722 and move along the sliding groove 721 relative to the conductive rod 41, effectively preventing the upper contact portion 42 and the conductive component 3 from being crushed. During this process, the upper contact portion 42 maintains contact with the conductive component 3, ensuring that the alarm module 53 is always in the alarm state. When resetting, the upper contact portion 42 can automatically fall and move to the position of the limiting magnet 722 under the action of its own gravity and the magnetic force of the limiting magnet 722, achieving the purpose of automatic reset.

[0089] Similarly, the connecting piece 72 for connecting the lower contact portion 43 is also constructed with a sliding groove 721 arranged along the length direction of the conductive rod 41. The lower contact portion 43 is provided with a sliding block 421 adapted to the sliding groove 721. The sliding block 421 is constrained in the sliding groove 721 and can slide along the sliding groove 721. A support spring 723 is provided in the sliding groove 721. The upper end of the support spring 723 is connected to the sliding block 421, and the lower end of the support spring 723 is connected to the bottom of the sliding groove 721. The support spring 723 is used to support the lower contact portion 43, so that initially, the lower contact portion 43 is located at a set position away from the lower end of the sliding groove 721. Figure 27 As shown. In actual use, when the pressure between the lower contact portion 43 and the conductive component 3 is excessive, the lower contact portion 43 can overcome the elastic force of the support spring 723 and automatically move downward relative to the conductive rod 41, effectively preventing the lower contact portion 43 and the conductive component 3 from being crushed. During this process, the lower contact portion 43 maintains contact with the conductive component 3, ensuring that the alarm module 53 remains in the alarm state. When resetting, the lower contact portion 43 can automatically move to the initial position under the elastic force of the support spring 723, achieving the purpose of automatic reset.

[0090] In order to prevent the metal part 61 in the conductive component 3 from being crushed when the displacement is too large or the tilt angle is too large, the front and rear adjustment mechanism 6 further includes a movable plate 612 and a preload spring 614. Figure 28 As shown, the movable plate 612 is also made of metal plate. The movable plate 612 can be constrained to move forward and backward on the metal member 61. Two mutually parallel limiting strips 613 are provided on the upper surface of the metal member 61. The movable plate 612 can be constrained to move between the two limiting strips 613. Figure 28 As shown, the lower surface of the movable plate 612 can fit the metal part 61, so that the movable plate 612 is electrically connected to the metal part 61, and the arc-shaped groove 611 is constructed on the movable plate 612. The metal part 61 does not need to construct the arc-shaped groove 611. At the same time, the end of the limit bar 613 close to the conductive rod 41 is closed, and the side of the movable plate 612 is constructed with a step that adapts to the front end of the limit bar 613. One end of the pre-tightening spring 614 is connected to the movable plate 612, and the other end is connected to the metal part 61. The pre-tightening spring 614 is arranged in the front-to-back direction, as shown in FIG. Figure 28As shown, initially, the movable plate 612 is pressed against the inner end of the limit bar 613 by the elastic force of the preload spring 614. During use, the distance between the two movable plates 612 can be adjusted by adjusting the distance between the two metal parts 61. During use, the metal part 61 does not directly contact the conductive rod 41, but instead uses the movable plate 612 to contact the conductive rod 41. When the pressure between the conductive rod 41 and the movable plate 612 is too high, the movable plate 612 can overcome the elastic force of the preload spring 614 and move relative to the metal part 61, effectively preventing the conductive rod 41 and the movable plate 612 from being crushed. During this process, the movable plate 612 maintains contact with the conductive rod 41, ensuring that the alarm module 53 is always in the alarm state. When resetting, the movable plate 612 can automatically move to the initial position under the elastic force of the preload spring 614, achieving the purpose of automatic reset.
