DETAILED DESCRIPTION

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] like Figures 1 to 5 As shown, an intelligent monitoring and alarm device for roadbed slopes includes a plurality of monitoring devices 1 distributed on the slope. The monitoring device 1 includes a mounting base 2, a support 3, and a monitoring box 4. The support 3 is assembled between the mounting base 2 and the monitoring box 4. The mounting base 2 is used to be installed on the slope. The monitoring box 4 is provided with an alarm module 5. The front and rear sides and the left and right end surfaces of the monitoring box 4 are all provided with trigger components.

[0030] The trigger assembly includes a support 6, a trigger block 7, and two sets 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 sets of trigger switches 8 are respectively arranged at the end of the support 6 close to the monitoring box 4 (proximal trigger switch 8) and the end far away from the monitoring box 4 (distal trigger switch 8). The trigger block 7 is located between the two sets of trigger switches 8. The trigger switches 8 are electrically connected to the alarm module 5.

[0031] One end of the trigger block 7 away from the monitoring box 4 is connected to a pull rope 9, and the other end of the pull rope 9 passes through the support 6 and extends outward. When in working condition, the pull ropes 9 on the two trigger blocks 7 on adjacent sides of two adjacent monitoring devices 1 are connected as one, and 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 the two adjacent monitoring devices 1 are installed, the pull rope 9 connecting the trigger blocks 7 on both sides is stretched and pulled, and the trigger block 7 overcomes the resistance of the spring 10 and moves toward the middle of the support 6. At this time, the trigger block 7 stops at the equilibrium position between the two groups of trigger switches 8, forming a stable structure in the non-trigger state.

[0032] The working principle of this device is as follows: adjacent monitoring devices 1 are linked together by pull ropes 9 to form a network monitoring system. When the slope is displaced, the change in the spacing between adjacent devices will cause the tension of the pull rope 9 to change: when the spacing increases, the tension on the pull 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 far-end trigger switch 8. When the spacing decreases, the pull rope 9 relaxes, and the spring 10 rebounds and pushes the trigger block 7 toward the near-end trigger switch 8. When any trigger switch 8 is triggered, an early warning will be issued through the alarm module 5 and a signal will be sent to the back-end management office. The design of the two trigger switches 8 ensures that the alarm can be triggered when the monitoring device 1 moves in any direction, and the direction of slope displacement can be distinguished at the same time.

[0033] In this embodiment, a connecting seat 11 is installed on the pillar 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 rotation resistance between the rotating shaft and the support rods 12. A bearing seat 13 is provided 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, and a fixing ring 16 is provided on the end of the pull rope 9 close to the support 6. A tether 17 is connected between the fixing ring 16 and the counterweight 15. When the counterweight 15 slides off the bearing seat 13, the pull rope 9 will be pulled under the action of gravity;

[0034] This device also has a tilt trigger mechanism. When the slope shows signs of instability and failure, the monitoring device 1 tilts, causing the supporting seat 13 to no longer be in a horizontal state. The counterweight block 15 slides off the supporting seat 13 under the action of gravity, and due to its own weight, it pulls the pull rope 9 through the tether 17, forcing the trigger block 7 to move, thereby triggering the alarm. The tilt trigger can be used as a supplementary monitoring method for landslide precursors.

[0035] In this embodiment, a bellows 18 is provided on the outer side of the pull rope 9. Both ends of the bellows 18 are provided with fixing members 27. A snap ring 19 is provided on the end of the support 6 away from the monitoring box 4. The fixing member 27 and the snap ring 19 are detachably connected. The bellows 18 is used to connect between adjacent sides of two adjacent monitoring devices 1. When the pull rope 9 is in a stretched installation state, the bellows 18 remains in a stretched working state and has a certain amount of deformation margin.

[0036] When installing the bellows 18, first compress the bellows 18 and clip one end of it onto the support 6 of one of the monitoring devices 1. Then, pass the pull rope 9 thereinto into the bellows 18 and out from the other end. After the pull ropes 9 on both sides are connected and straightened, stretch the bellows 18 and clip the other end onto the other monitoring device 1 to complete the installation. The bellows 18 is sleeved on the outside of the pull rope 9, thereby effectively protecting the pull rope 9. When strong winds or rain occur, 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.

[0037] 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 presence of the bellows 18, so that the pull rope 9 can smoothly pull the trigger block 7.

[0038] In this embodiment, two or three fixing components are evenly spaced on the mounting base 2, and the fixing 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 provided in the base 20. One end of the screw rod 23 penetrates and extends out of one end of the mounting base 2 of the base 20. A knob 24 is rotatably provided 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 provided 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.

[0039] When installing the monitoring device 1, the screw rod 23 can be rotated by turning the knob 24, thereby driving the movable base 21 to move horizontally. After the movable base 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 fixation 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 area around the fixed base. It is easy for the slope slightly farther away from the stabilizing pile 22 to deform, but this displacement cannot be transmitted to the stabilizing pile 22.

[0040] In this device, multiple stabilizing piles 22 are inserted into the slope in different directions. When local deformation occurs in the areas around and between 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.

[0041] In the embodiment, the alarm module 5 comprises a power supply, a controller, a wireless transceiver module and a positioning module, the top surface of the monitoring box 4 is provided with an alarm lamp 29 electrically connected with the controller; the trigger switch 8 directly controls the alarm lamp 29 to flash, realizing on-site warning, warning passing vehicles and pedestrians to pay attention, sending alarm coordinates to the management platform through the wireless transceiver module, supporting emergency response scheduling.

[0042] In the embodiment, the top of the support 6 is provided with a positioning opening 26 located at the middle between the two trigger blocks 7, and a fixing member 27 is detachably inserted into the positioning opening 26, and the top of the trigger block 7 is provided with a clamping opening 28 corresponding to the fixing member 27;

[0043] When the monitoring device 1 is connected with the pull rope 9, the pull rope 9 is first pulled to move the trigger block 7 to the balance position, and then the fixing member 27 is inserted into the positioning opening 26 until the fixing member 27 is inserted into the clamping opening 28, at this time, the trigger block 7 is positioned and fixed under the limiting action of the fixing member 27, then the two pull ropes 9 can be straightened and tied together by the staff, and the excess part is cut off, and finally the fixing member 27 can be taken out after the two pull ropes 9 are connected, and the trigger block 7 remains stationary under the synergistic action of the straightened pull rope 9 and the spring 10; the positioning and fixing by the fixing member 27 make it unnecessary to deliberately control the position of the trigger block 7 when connecting the two 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.

[0044] The embodiment also provides an installation method of the roadbed slope intelligent monitoring alarm device.

[0045] S1, horizontally fix the installation base 2 at a preset position on the slope surface to ensure that the installation base 2 is attached to the slope surface, and complete the installation of the monitoring device 1;

[0046] S2, straighten the two pull ropes 9 between two adjacent monitoring devices 1, and move the trigger block 7 to the balance position between the two trigger switches 8 by pulling the pull rope 9;

[0047] S3, tie the two pull ropes 9 together while keeping the trigger blocks 7 on both sides in the balance position, to ensure that the tied pull ropes 9 remain straight;

[0048] S4, repeat the above operation to connect the trigger blocks 7 of the monitoring devices 1 in front, back, left and right directions with the trigger blocks 7 of the adjacent devices on the corresponding side through the pull ropes 9; any deviation of the monitoring device 1 will cause the trigger block 7 to deviate from the balance position and touch any trigger switch 8, thereby activating the corresponding signal path of the alarm module 5.

[0049] S5, adjust the bearing seat 13 to the horizontal state, through the tether 17 connecting the counterweight 15 and the fixed ring 16 of the pull rope 9, place the counterweight 15 on the bearing seat 13; wherein the counterweight 15 on the monitoring device 1 at the lowermost side is directly connected with the trigger block 7 through the tether 17.

[0050] Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can make modifications to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to part of the technical features, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
