Description

Technical Field

[0001] The present invention relates to the technical field of slope monitoring, and specifically to an intelligent monitoring and alarm device and method for a roadbed slope. Background Technique

[0002] Currently, the main monitoring methods for slopes are simple observation methods, station observation methods, instrument observation methods, remote monitoring methods, etc. Due to reasons such as harsh and changeable on-site monitoring environments, complex and diverse monitoring objects, many interference factors, large monitoring ranges and scales, and imperfect analysis theories and warning criteria, these traditional conventional monitoring methods have many deficiencies, which are mainly reflected in: (1) highly dependent on the construction of sensor networks, with poor durability and long-term stability, and high monitoring costs; (2) the monitoring instruments are affected by factors such as electromagnetic interference in the environment, resulting in unclear monitoring effects, and even adverse phenomena such as missed detections, and weak long-distance or large-area monitoring capabilities. Summary of the Invention

[0003] The purpose of the present invention is to provide an intelligent monitoring and alarm device and method for a roadbed slope to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the present invention provides the following technical solution: An intelligent monitoring and alarm device for a roadbed slope includes a number of monitoring devices distributed on the slope. The monitoring device includes a mounting base, a support column, and a monitoring box. The support column is assembled between the mounting base and the monitoring box. The mounting base is used to be installed on the slope. An alarm module is arranged in the monitoring box. Trigger components are arranged on the front, back, left, and right end faces of the monitoring box; The trigger component includes a support, a trigger block, and two groups of trigger switches. The support is fixed to the side end of the monitoring box. The trigger block is horizontally slidably assembled inside the support. The two groups of trigger switches are respectively arranged at the end of the support close to the monitoring box and the end far from the monitoring box. The trigger block is located between the two groups of trigger switches. The trigger switch is electrically connected to the alarm module; One end of the trigger block far from the monitoring box is connected to a pull rope. The other end of the pull rope penetrates through the support and extends outwards. When in the working state, the pull ropes on the adjacent sides of the two adjacent trigger blocks on two adjacent monitoring devices are connected as a whole. A spring is connected between the trigger block and the inner wall of the support. When the spring is in the initial state, the trigger block abuts against the trigger switch on the side close to the monitoring box. When two adjacent monitoring devices are installed, the pull ropes connecting the two side trigger blocks are straightened and pulled, and the trigger block moves towards the middle of the support against the spring resistance. At this time, the trigger block stops at the balance position between the two groups of trigger switches, forming a non-trigger state stable structure.

[0005] Further, the trigger switch is a travel switch, a micro switch, or other mechanical contact switches.

[0006] Furthermore, a connecting seat is installed on the pillar, and symmetrically distributed support rods extend from the left and right ends of the connecting seat. A rotating shaft is rotatably connected between the front ends of the two support rods, and there is a certain rotational resistance between the rotating shaft and the support rods. A bearing seat is provided on the rotating shaft, and a bubble level is embedded on the bearing seat. A counterweight is placed on the top surface of the bearing seat. A fixing ring is provided on the end of the pull rope close to the support, and a tether is connected between the fixing ring and the counterweight. When the counterweight slides off the bearing seat, the pull rope will be pulled under the action of gravity.

[0007] Furthermore, a corrugated tube is provided on the outer side of the pull rope, fixings are provided at both ends of the corrugated tube, a clamping ring is provided on the end of the support away from the monitoring box, the fixings and the clamping ring are detachably connected, and the corrugated tube is used to connect between adjacent sides of two adjacent monitoring devices; and when the pull rope is in a stretched installation state, the corrugated tube remains in a stretched working state, and a certain deformation margin space is left.

[0008] Furthermore, a plurality of fixed components are evenly spaced on the mounting base, and the fixed components include a base, a movable base and a stabilizing pile. The base is fixedly connected to the mounting base, a screw is rotatably arranged in the base, one end of the screw extends through one end of the mounting base of the base principle, a knob is rotatably arranged on the top surface of the base, the rotating shaft of the knob is connected to the screw through a bevel gear transmission, the movable base is threadedly connected to the screw, a plurality of guide rods are arranged on the movable base, a plurality of corresponding sliding holes are opened on the base, the guide rods are slidably assembled in the sliding holes, and a stabilizing hole for the stabilizing pile to pass through is opened on the movable base.

[0009] Furthermore, the alarm module includes a power supply, a controller, a wireless transceiver module and a positioning module. The top surface of the monitoring box is provided with an alarm light, and the alarm light is electrically connected to the controller.

[0010] Furthermore, a positioning opening is provided on the top of the support, and the positioning opening is located in the middle between the trigger blocks on both sides. A fixing piece is detachably inserted into the positioning opening, and a snap-in corresponding to the fixing piece is provided on the top of the trigger block.

[0011] The present invention also provides a method for installing the above-mentioned intelligent monitoring alarm device, comprising the following steps: S1. Fix the installation base horizontally at the preset position on the slope surface to ensure that it fits the slope surface and complete the installation of the monitoring device; S2. Horizontally straighten the pull ropes on both sides between two adjacent monitoring devices, and move the trigger block to the balance position between the two sets of trigger switches by pulling the pull ropes; S3. While keeping the trigger blocks on both sides in the balanced position, tie the pull ropes on both sides together to ensure that the tied pull ropes remain taut; S4. Repeat the above operations to connect the trigger blocks in the front, rear, left, and right directions of the monitoring device to the trigger blocks of the adjacent devices on the corresponding sides through pull ropes. Any deviation of the monitoring device will cause the trigger block to move out of the balanced position and touch any trigger switch, thereby activating the corresponding signal path of the alarm module; Further, it also includes step S5. Adjust the bearing base to a horizontal state, connect the counterweight block to the fixed ring of the pull rope through a tether, and place the counterweight block on the bearing base.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention has multi-dimensional dynamic monitoring capabilities. Through the design of double trigger switches at the proximal and distal ends, it can simultaneously monitor the expansion and contraction displacement directions of the slope, and distinguish the displacement types through the alarm module to provide more accurate early warning information. Combined with the horizontal bearing base and the counterweight block sliding linkage system, it can trigger an alarm when the slope tilts but no significant displacement has occurred, effectively capturing the early signals of landslide precursors; (2) The present invention has a networked monitoring system. By linking adjacent monitoring devices through pull ropes to form a coverage network, a single-point displacement can trigger multi-point responses, enhancing the ability to capture changes in the overall stability of the slope; The trigger switch directly controls the flashing of on-site alarm lights (warning vehicles and pedestrians), and at the same time sends the coordinates to the management platform through the wireless module to achieve dual on-site and remote emergency responses.

Detailed implementation manners

[0015] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0016] As Figures 1 to 5 shown, a smart monitoring and alarm device for a roadbed slope includes a plurality of monitoring devices 1 distributed on the slope. The monitoring device 1 includes a mounting base 2, a support column 3, and a monitoring box 4. The support column 3 is assembled between the mounting base 2 and the monitoring box 4. The mounting base 2 is used for mounting on the slope. An alarm module 5 is arranged in the monitoring box 4. Trigger components are arranged on the front, back, left, and right end faces of the monitoring box 4. The trigger component includes a support 6, a trigger block 7, and two groups of trigger switches 8. The support 6 is fixed to the side end of the monitoring box 4. The trigger block 7 is horizontally slidably assembled inside the support 6. The two groups of trigger switches 8 are respectively arranged at the end near the monitoring box 4 (proximal trigger switch 8) and the end far from the monitoring box 4 (distal trigger switch 8) inside the support 6. The trigger block 7 is located between the two groups of trigger switches 8. The trigger switch 8 is electrically connected to the alarm module 5. One end of the trigger block 7 far from the monitoring box 4 is connected to a pull rope 9. The other end of the pull rope 9 penetrates through the support 6 and extends outwards. When in the working state, the pull ropes 9 on the adjacent sides of the two adjacent trigger blocks 7 on two adjacent monitoring devices 1 are connected as a whole. A spring 10 is connected between the trigger block 7 and the inner wall of the support 6. When the spring 10 is in the initial state, the trigger block 7 abuts against the trigger switch 8 on the side close to the monitoring box 4. When two adjacent monitoring devices 1 are installed, the pull rope 9 connecting the two trigger blocks 7 on both sides is straightened and pulled. The trigger block 7 moves towards the middle of the support 6 against the resistance of the spring 10. At this time, the trigger block 7 stops at the balance position between the two groups of trigger switches 8, forming a non - triggered stable structure.

[0017] The working principle of this device is as follows: Adjacent monitoring devices 1 are linked through a pulling rope 9 to form a network monitoring system. When the slope undergoes displacement, the change in the distance between adjacent devices will cause the tension of the pulling rope 9 to change. When the distance increases, the pulling force on the pulling rope 9 increases, and the trigger block 7 overcomes the resistance of the spring 10 and moves away from the monitoring box 4, contacting the distal trigger switch 8. When the distance decreases, the pulling rope 9 becomes slack, and the spring 10 rebounds to push the trigger block 7 towards the proximal trigger switch 8. After any one of the trigger switches 8 is triggered, it will issue a warning through the alarm module 5 and send a signal to the back-end management office. The design of the two trigger switches 8 can ensure that the monitoring device 1 can trigger an alarm when it displaces in any direction, and at the same time, the direction of slope displacement can be distinguished.

[0018] In this embodiment, a connecting seat 11 is installed on the support column 3, and symmetrically distributed support rods 12 extend from its left and right ends. A rotating shaft is rotatably connected between the front ends of the two support rods 12, and there is a certain rotational resistance between the rotating shaft and the support rod 12. A bearing seat 13 is arranged on the rotating shaft, and a bubble level 14 is embedded in the bearing seat 13. The bubble level 14 is used to assist in adjusting the bearing seat 13 to ensure that the bearing seat 13 is in a horizontal state. A counterweight 15 is placed on the top surface of the bearing seat 13. A fixing ring 16 is arranged at one end of the pulling rope 9 close to the support 6, and a connecting rope 17 is connected between the fixing ring 16 and the counterweight 15. When the counterweight 15 slides off the bearing seat 13, it will pull the pulling rope 9 under the action of gravity. This device also has an inclination trigger mechanism. When there are precursors of slope instability and failure, at this time, the monitoring device 1 inclines, resulting in the bearing seat 13 not being in a horizontal state. The counterweight 15 slides off the bearing seat 13 under the action of gravity and pulls the pulling rope 9 through the connecting rope 17 due to its own weight, forcing the trigger block 7 to displace to trigger an alarm. Inclination triggering can be used as a supplementary monitoring means for landslide precursors.

[0019] In this embodiment, a corrugated pipe 18 is sleeved outside the pulling rope 9. Fixing members 27 are arranged at both ends of the corrugated pipe 18. A snap ring 19 is arranged at one end of the support 6 away from the monitoring box 4. The fixing member 27 and the snap ring 19 are detachably clamped. The corrugated pipe 18 is used to connect between the adjacent sides of two adjacent monitoring devices 1. And when the pulling rope 9 is in a straightened installation state, the corrugated pipe 18 remains in a stretched working state and has a certain deformation margin space. When installing the bellows 18, first compress the bellows 18 and clamp one end of it on the support 6 of one of the monitoring devices 1, and then pass the pull rope 9 therein into the bellows 18 and out from the other end, then connect the pull ropes 9 on both sides and straighten them, stretch the bellows 18 and clamp the other end on another monitoring device 1, so as to complete the installation; the bellows 18 is sleeved on the outside of the pull rope 9, so as to effectively protect the pull rope 9. When there is strong wind or rain, it can prevent external factors such as wind and rain from directly contacting the pull rope 9 and causing the pull rope 9 to move, thereby greatly reducing the probability of false triggering; When the slope is displaced and deformed, the distance between the two monitoring devices 1 increases. The deformation margin space can ensure that the movement of the two monitoring devices 1 will not be restricted by the existence of the bellows 18, so that the pull rope 9 can smoothly pull the trigger block 7.

[0020] In this embodiment, two or three fixed components are evenly spaced on the mounting base 2, and the fixed components include a base 20, a movable base 21 and a stabilizing pile 22. The base 20 is fixedly connected to the mounting base 2, and a screw rod 23 is rotatably arranged in the base 20. One end of the screw rod 23 penetrates and extends out of the base 20 to form an end of the mounting base 2. A knob 24 is rotatably arranged on the top surface of the base 20. The rotating shaft of the knob 24 is connected to the screw rod 23 through a bevel gear transmission. The movable base 21 is threadedly connected to the screw rod 23. A plurality of guide rods 25 are arranged on the movable base 21. A plurality of corresponding sliding holes are opened on the base 20. The guide rods 25 are slidably assembled in the sliding holes. A stabilizing hole 30 for the stabilizing pile 22 to pass through is opened on the movable base 21. When installing the monitoring device 1, the screw rod 23 can be rotated by turning the knob 24, thereby driving the movable seat 21 to move horizontally. After the movable seat 21 is moved outward to a certain distance, the stabilizing pile 22 is vertically inserted into the slope through the stabilizing hole 30, thereby achieving the fixing of the installation base 2. On the one hand, this design can adapt to the anchoring requirements of different geological conditions. On the other hand, compared with the single-point anchoring structure, the monitoring device 1 will only be offset when the slope geology within the range of the anchoring point is deformed. Its monitoring area is limited to a very small range around the fixed base. It is easy for the slope slightly farther away from the stabilizing pile 22 to be deformed, but the displacement cannot be transmitted to the stabilizing pile 22. In this device, multiple stabilizing piles 22 are inserted into the slope in different directions. When local deformation occurs in the areas around and covered by each stabilizing pile 22, the displacement within the range of adjacent anchor points will be transmitted to the mounting base 2, causing the mounting base 2 to tilt to the corresponding side, thereby increasing the monitoring range.

[0021] In this embodiment, the alarm module 5 includes a power supply, a controller, a wireless transceiver module, and a positioning module. An alarm lamp 29 is provided on the top surface of the monitoring box 4, and the alarm lamp 29 is electrically connected to the controller; the trigger switch 8 directly controls the flashing of the alarm lamp 29 to achieve on-site warning, warning passing vehicles and pedestrians to pay attention, and sending the alarm coordinates to the management platform through the wireless transceiver module to support emergency response scheduling.

[0022] In this embodiment, a positioning port 26 is opened at the top of the support 6. The positioning port 26 is located in the middle between the two side trigger blocks 7. A fixing member 27 is detachably inserted into the positioning port 26. A bayonet 28 corresponding to the fixing member 27 is opened at the top of the trigger block 7; When the monitoring device 1 is connecting the pull rope 9, first pull the pull rope 9 to make it pull the trigger block 7 to move to the balanced position, then insert it into the positioning port 26 until the fixing member 27 is inserted into the bayonet 28. At this time, the trigger block 7 is positioned and fixed under the limiting action of the fixing member 27. Then the staff can straighten and tie the two side pull ropes 9 together and cut off the redundant part. Finally, after connecting the two side pull ropes 9, the fixing member 27 can be taken out, and the trigger block 7 will remain stationary under the combined action of the straightened pull rope 9 and the spring 10; positioning and fixing through the fixing member 27 makes it unnecessary to deliberately control the position of the trigger block 7 when connecting the two side pull ropes 9, avoiding the complexity of manually adjusting the position of the trigger block 7, improving the installation efficiency and reducing the operation error.

[0023] This embodiment also provides an installation method for the above-mentioned intelligent monitoring and alarm device for subgrade slopes, including the following steps: S1. Horizontally fix the installation base 2 at a preset position on the slope surface to ensure it fits with the slope surface, and complete the installation of the monitoring device 1; S2. Horizontally straighten the two side pull ropes 9 between two adjacent monitoring devices 1, and move the trigger block 7 to the balanced position between the two groups of trigger switches 8 by pulling the pull rope 9; S3. While keeping the two side trigger blocks 7 in the balanced position, tie the two side pull ropes 9 together to ensure that the tied pull rope 9 remains in a straightened state; S4. Repeat the above operations to connect the trigger blocks 7 in the front, rear, left, and right directions of the monitoring device 1 with the trigger blocks 7 of the adjacent devices on the corresponding side through the pull rope 9; any deviation of the monitoring device 1 will cause the trigger block 7 to move out of the balanced position and touch any one of the trigger switches 8, thereby activating the corresponding signal path of the alarm module 5.

[0024] S5. Adjust the bearing seat 13 to a horizontal state, connect the counterweight 15 and the fixing ring 16 of the pull rope 9 through the tie rope 17, and place the counterweight 15 on the bearing seat 13; among them, the counterweight 15 on the lowermost monitoring device 1 is directly connected to the trigger block 7 through the tie rope 17.
