Description

Technical Field

[0001] The present invention belongs to the technical field of highway high slope monitoring, and specifically relates to an intelligent monitoring and early warning device for the stability of highway high slopes. Background Art

[0002] Highway high slopes usually refer to slopes with relatively large heights formed due to terrain undulation or engineering needs during highway construction. The height, slope, and geological conditions of these slopes may be relatively complex, which have important impacts on the stability and safety of highways. The main purpose of highway high slope detection is to timely grasp the stability conditions such as displacement and deformation of the slopes, prevent the occurrence of slope instability accidents, and ensure the safe operation of highways. Currently, the stability monitoring of highway high slopes usually includes geological exploration combined with means such as drilling, sampling, and testing to obtain geological data of the high slopes; remote sensing monitoring obtains image data of the high slopes through methods such as satellite images or UAV aerial photography; ground displacement observation arranges measuring instruments such as total stations and GPS receivers on the high slopes to continuously observe the displacement of the slopes; the above methods cannot monitor the hollowing conditions of high slopes, and the existing hollowing monitoring of highway high slopes usually includes methods such as the knocking method, ultrasonic detection method, infrared thermal imaging method, and core sampling method. The above methods have problems such as inaccurate monitoring data, high monitoring costs, and easy damage to highways, and it is also difficult to accurately and real-time monitor the hollowing conditions of high slopes. Therefore, an intelligent monitoring and early warning device for the stability of highway high slopes is proposed. Summary of the Invention

[0003] To solve the problems raised in the above background art, the present invention provides an intelligent monitoring and early warning device for the stability of highway high slopes, which solves the problems of high monitoring costs and easy damage to highways in the existing hollowing monitoring of highway high slopes, and also solves the problem of difficult accurate and real-time monitoring of the hollowing conditions of high slopes.

[0004] To achieve the above object, the present invention provides the following technical solution: An intelligent monitoring and early warning device for the stability of highway high slopes, including a support frame arranged on a high slope highway, and further including: A monitoring component, which is arranged inside the support frame and is used for emitting elastic waves; A data acquisition component, which is arranged inside the highway high slope and is used for receiving elastic waves generated by the transmission component; A transmission component, which is installed inside the support frame; Among them, the monitoring component includes a transmission box girder sliding inside the support frame, an impact rod is movably sleeved on the transmission box girder, a limiting plate is fixedly installed on the outside of the impact rod, a metal semi-circular member is fixedly installed inside the support frame, the metal semi-circular member is in a horn shape, and the metal semi-circular member is coaxially vertical with the impact rod; A rectangular through groove is formed on the outer side of the transmission box girder. A spring telescopic rod is hinged to the inner wall of the support frame. The spring telescopic rod is located in the rectangular through groove and the other end is hinged to the upper end of the impact rod. A first magnet is fixedly installed at the upper end of the impact rod, and a second magnet is fixedly installed on the transmission box girder. In the initial state, the first magnet is adsorbed to the second magnet. When a road vehicle drives and presses down the transmission box girder, the impact rod is driven to impact the metal semi-circular part to generate elastic waves. After the impact rod impacts, it is blocked by the metal semi-circular part and moves upward and resets under the action of the spring telescopic rod. The first magnet is separated from the second magnet, and the bottom of the impact rod is separated from the metal semi-circular part.

[0005] Preferably, the data acquisition component includes a horizontal plate arranged in the road. A monitoring module is arranged on the horizontal plate, and data processing devices electrically connected to the monitoring module are arranged at both ends of the horizontal plate. The monitoring module includes a displacement monitoring sensor, a pressure monitoring sensor, an environmental monitoring sensor, and an elastic wave receiving sensor.

[0006] Preferably, the monitoring component further includes a fixing frame fixedly installed inside the support frame. A first elastic sheet for upwardly propping the transmission box girder is arranged at the top of the fixing frame.

[0007] Preferably, the monitoring component further includes a cross beam fixedly installed on the inner wall of the support frame. A protection pad is fixedly installed at the top of the support frame. The protection pad is made of rubber material. A stable groove for limiting the cross beam is formed at the top of the transmission box girder.

[0008] Preferably, the transmission component includes a clamping plate movably arranged inside the support frame. A damping pad is arranged at one end of the clamping plate. A clamping groove is formed on the side of the transmission box girder.

[0009] Preferably, a fixing plate is fixedly installed at the bottom of the clamping plate. A second elastic sheet is connected between the fixing plate and the support frame. When the transmission box girder moves downward, the clamping plate is clamped inside the clamping groove under the action of the second elastic sheet to limit the transmission box girder.

[0010] Preferably, the transmission component further includes a transmission rod hinged inside the support frame. Docking grooves are formed at both ends of the transmission rod. A second docking rod is fixedly installed at one end of the clamping plate. The second docking rod moves in the docking groove at one end of the transmission rod.

[0011] Preferably, a convex plate is movably arranged inside the support frame. Sliders are fixedly installed on both sides of the convex plate. Vertical sliding grooves for the vertical sliding of the sliders are formed in the inner wall of the support frame. A first docking rod is fixedly installed at the bottom of the convex plate, and the first docking rod is movably located in the docking groove at the other end of the transmission rod; In the initial state, the raised part of the transmission box girder is higher than the top of the support frame. The convex plate is flush with the top of the support frame. When the damping pad of the transmission box girder moves downward and is engaged in the card slot, it drives the transmission rod to rotate and push the convex plate upward.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the weight of the vehicle presses down the transmission box girder. Since the first magnet contacts the second magnet in the initial state, it drives the impact rod to move downward synchronously to impact the metal semi-circle and generate elastic waves. The metal semi-circle is designed in a horn shape, which improves the diffusion of elastic waves. The elastic waves spread downward along the road. The monitoring module receives the elastic wave data, and the processing device records it and transmits it to the control room. By comparing the received elastic waves with the elastic waves monitored on the standard road, if there is an air pocket phenomenon on the high slope of the road, there will be a difference between the received elastic waves and the standard monitored elastic waves, and it can be judged that there is an air pocket phenomenon on the high slope of the road; In the present invention, during the process of the vehicle's own weight pressing down the transmission box girder and the impact rod, the impact rod impacts the metal semi-circle to generate elastic waves. After the impact rod moves downward and impacts the metal semi-circle, the impact rod is blocked by the metal semi-circle and cannot move downward. At this time, the first magnet is separated from the second magnet, and the impact rod moves upward under the action of the spring telescopic rod, so that the bottom of the impact rod does not contact the metal semi-circle, avoiding the impact rod absorbing the elastic waves generated by the metal semi-circle and reducing the propagation of elastic waves; In the present invention, the front wheel of the vehicle driving on the road presses down the transmission box girder, making the card slot and the card plate horizontal. The card plate is engaged in the card slot under the action of the second elastic sheet. During the movement of the card plate, one end of the transmission rod is pulled through the second docking rod, so that the transmission rod rotates at the hinge joint with the support frame, and the upper end of the transmission rod pushes the convex plate to move upward and protrude above the top of the support frame. At this time, the transmission box girder is limited inside the support frame by the card plate being engaged in the card slot, avoiding the rapid reset of the transmission box girder, thus ensuring that the elastic waves generated by the metal semi-circle have sufficient propagation time, and further improving the monitoring effect of the air pocket condition of the high slope of the road.

Specific embodiments

[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 8 shown, the present invention provides an intelligent monitoring and early warning device for the stability of highway high slopes, including a support frame 1 embedded in the highway of the high slope, and further including: A monitoring component 3, which is arranged inside the support frame 1 and is used to emit elastic waves; A data acquisition component 2, which is arranged inside the highway high slope and is used to receive the elastic waves generated by the transmission component 4; A transmission component 4, which is installed inside the support frame 1; Among them, the monitoring component 3 includes a transmission box girder 31 that slides inside the support frame 1. An impact rod 35 is movably sleeved on the transmission box girder 31. A limiting plate 36 is fixedly installed on the outside of the impact rod 35. A metal semi-circular member 37 is fixedly installed inside the support frame 1. The metal semi-circular member 37 is in a horn shape and is coaxial and vertical with the impact rod 35; A rectangular through groove 38 is opened on the outside of the transmission box girder 31. A spring telescopic rod 33 is hinged to the inner wall of the support frame 1. The spring telescopic rod 33 is located in the rectangular through groove 38 and the other end is hinged to the upper end of the impact rod 35; A first magnet 34 is fixedly installed at the upper end of the impact rod 35. A second magnet 39 is fixedly installed on the transmission box girder 31; In the initial state, the first magnet 34 is adsorbed to the second magnet 39. When a road vehicle travels and presses down the transmission box girder 31, it drives the impact rod 35 to strike the metal semi-circular member 37 to generate elastic waves; After the impact rod 35 strikes, it is blocked by the metal semi-circular member 37 and moves upward and resets under the action of the spring telescopic rod 33. The first magnet 34 is separated from the second magnet 39, and the bottom of the impact rod 35 is separated from the metal semi-circular member 37; The data acquisition component 2 includes a horizontal plate 22 arranged inside the road. A monitoring module 23 is arranged on the horizontal plate 22. Data processing devices 21 electrically connected to the monitoring module 23 are arranged at both ends of the horizontal plate 22; The monitoring module 23 includes a displacement monitoring sensor, a pressure monitoring sensor, an environmental monitoring sensor, and an elastic wave receiving sensor; The monitoring component 3 further includes a fixing frame 321 fixedly installed inside the support frame 1. A first elastic sheet 322 that upwardly supports the transmission box girder 31 is arranged at the top of the fixing frame 321.

[0017] The support frame 1 and the data acquisition component 2 are embedded in the road. When a vehicle travels on the road and passes over the transmission box girder 31, the weight of the vehicle presses down the transmission box girder 31 to compress the first elastic sheet 322. Since the first magnet 34 is in contact with the second magnet 39 in the initial state, it drives the impact rod 35 to move downward synchronously to strike the metal semi-circular member 37 to generate elastic waves. The metal semi-circular member 37 is designed in a horn shape to improve the diffusion of the elastic waves. The elastic waves spread downward along the road. The monitoring module 23 receives the elastic wave data, and the data processing device 21 records it and transmits it to the control room. By comparing the received elastic waves with the elastic waves monitored by the standard road, if there is a phenomenon of hollowing in the high slope of the road, there will be a difference between the received elastic waves and the standard monitored elastic waves, and it can be judged that there is a phenomenon of hollowing in the high slope of the road; When the vehicle presses down on the transmission box girder 31 and the impact rod 35 by its own weight, the impact rod 35 impacts the metal semi-circular part 37 and emits elastic waves. After the impact rod 35 moves downward and impacts the metal semi-circular part 37, the impact rod 35 is blocked by the metal semi-circular part 37 and cannot move downward. At this time, the first magnet 34 disengages from contact with the second magnet 39, and the impact rod 35 moves upward under the action of the spring telescopic rod 33, so that the bottom of the impact rod 35 does not contact the metal semi-circular part 37, avoiding the impact rod 35 absorbing the elastic waves generated by the metal semi-circular part 37 and resulting in a reduction in the propagation of the elastic waves.

[0018] As Figures 4 - 6 shown, the monitoring component 3 further includes a cross beam 313 fixedly installed on the inner wall of the support frame 1. A protective pad 311 is fixedly installed on the top of the support frame 1. The protective pad 311 is made of rubber material, and a stable groove 312 for limiting the cross beam 313 is provided at the top of the transmission box girder 31.

[0019] When a vehicle driving on the road presses down on the transmission box girder 31 to compress the first elastic sheet 322, the transmission box girder 31 moves downward and seals the top of the support frame 1 through the protective pad 311, preventing sundries on the road from entering the interior of the support frame 1. At the same time, after the transmission box girder 31 moves downward, the cross beam 313 supports the transmission box girder 31 to ensure the stability of vehicle driving.

[0020] As Figure 4 、 Figure 5 and Figure 8 shown, the transmission component 4 includes a clamping plate 412 movably arranged inside the support frame 1. One end of the clamping plate 412 is provided with a damping pad 411, and a clamping groove 48 is provided on the side of the transmission box girder 31; A fixing plate 46 is fixedly installed at the bottom of the clamping plate 412, and a second elastic sheet 47 is connected between the fixing plate 46 and the support frame 1; When the transmission box girder 31 moves downward, the clamping plate 412 is clamped inside the clamping groove 48 under the action of the second elastic sheet 47 to limit the transmission box girder 31.

[0021] When a vehicle driving on the road presses down on the transmission box girder 31, the impact rod 35 impacts the metal semi-circular part 37 to generate elastic waves, and the data acquisition component 2 receives and processes the elastic waves to monitor the hollow condition of the highway high slope. During the downward movement of the transmission box girder 31, the clamping groove 48 and the clamping plate 412 remain horizontal. The clamping plate 412 is clamped inside the clamping groove 48 under the action of the second elastic sheet 47, and the transmission box girder 31 is limited by the clamping plate 412 to prevent the transmission box girder 31 from quickly resetting, so as to ensure that the elastic waves generated by the metal semi-circular part 37 have sufficient propagation time, thereby improving the monitoring effect of the hollow condition of the highway high slope.

[0022] As Figure 4 and Figure 5As shown in the figure, the transmission assembly 4 further includes a transmission rod 44 hinged inside the support frame 1. Docking grooves 43 are provided at both ends of the transmission rod 44. A second docking rod 45 is fixedly installed at one end of the clamping plate 412, and the second docking rod 45 is movably located in the docking groove 43 at one end of the transmission rod 44; A convex plate 41 is movably arranged inside the support frame 1. Sliders 40 are fixedly installed on both sides of the convex plate 41. Vertical sliding grooves 49 for the vertical sliding of the sliders 40 are provided on the inner wall of the support frame 1. A first docking rod 42 is fixedly installed at the bottom of the convex plate 41, and the first docking rod 42 is movably located in the docking groove 43 at the other end of the transmission rod 44; In the initial state, the transmission box girder 31 protrudes above the top of the support frame 1, the convex plate 41 is flush with the top of the support frame 1, and when the transmission box girder 31 moves downward, the damping pad 411 is engaged inside the card slot 48 to drive the transmission rod 44 to rotate upward and push the convex plate 41.

[0023] When the front wheels of the vehicle driving on the road press down the transmission box girder 31, the card slot 48 and the clamping plate 412 are kept horizontal. Under the action of the second elastic sheet 47, the clamping plate 412 is engaged inside the card slot 48. During the movement of the clamping plate 412, one end of the transmission rod 44 is pulled through the second docking rod 45, so that the transmission rod 44 rotates at the hinge joint with the support frame 1, and the upper end of the transmission rod 44 pushes the convex plate 41 to move upward and protrude above the top of the support frame 1. At this time, the transmission box girder 31 is limited inside the support frame 1 by engaging the clamping plate 412 inside the card slot 48, avoiding the rapid reset of the transmission box girder 31, so as to ensure that the elastic wave generated by the metal semi-circular part 37 has enough propagation time, and then improve the monitoring effect of the hollow situation of the highway high slope; When the vehicle on the road continues to drive, the rear wheels will press down the convex plate 41 to push the transmission rod 44 to rotate in the reverse direction, and pull the clamping plate 412 to move in the reverse direction to compress the second elastic sheet 47, disengaging from the inside of the card slot 48. At this time, the transmission box girder 31 loses its limit and resets above the top of the support frame 1 under the action of the first elastic sheet 322. At the same time, the first magnet 34 contacts the second magnet 39, and then the elastic wave generated by the next vehicle driving and pressing down the monitoring assembly 3 can be used to monitor the highway high slope, and this process is repeated to realize the real-time monitoring of the highway high slope.

[0024] The working principle and usage process of the present invention: Embed the support frame 1 and the data acquisition component 2 into the road. When a vehicle drives on the road and passes over the transmission box girder 31, the weight of the vehicle presses down the transmission box girder 31, compressing the first elastic piece 322. Since the first magnet 34 contacts the second magnet 39 in the initial state, the impact rod 35 is driven to move downward synchronously to impact the metal semi-circular part 37, generating elastic waves. The metal semi-circular part 37 is designed in a horn shape to improve the diffusion of the elastic waves. The elastic waves diffuse downward along the road. The monitoring module 23 receives the elastic wave data, and the processing device 21 records it and transmits it to the control room. By comparing the received elastic waves with the elastic waves of the standard road monitoring, if there is a hollow phenomenon on the high slope of the road, there will be a difference between the received elastic waves and the standard monitored elastic waves, and it can be judged that there is a hollow phenomenon on the high slope of the road; During the process of the impact rod 35 impacting the metal semi-circular part 37 by the downward pressure of the transmission box girder 31 and the impact rod 35 due to the vehicle's own weight, after the impact rod 35 moves downward and impacts the metal semi-circular part 37, the impact rod 35 is blocked by the metal semi-circular part 37 and cannot move downward. At this time, the first magnet 34 disengages from the contact with the second magnet 39, and the impact rod 35 moves upward under the action of the spring telescopic rod 33, so that the bottom of the impact rod 35 does not contact the metal semi-circular part 37, avoiding the impact rod 35 absorbing the elastic waves generated by the metal semi-circular part 37 and resulting in the reduction of the propagation of the elastic waves; When a vehicle drives on the road and presses down the transmission box girder 31 to compress the first elastic piece 322, the transmission box girder 31 moves downward and seals the top of the support frame 1 through the protection pad 311, preventing sundries on the road from entering the inside of the support frame 1. At the same time, after the transmission box girder 31 moves downward, the cross beam 313 supports the transmission box girder 31 to ensure the stability of the vehicle driving; When the front wheel of a vehicle driving on the road presses down the transmission box girder 31, the card slot 48 and the clamping plate 412 are kept horizontal. The clamping plate 412 is clamped inside the card slot 48 under the action of the second elastic piece 47. During the movement of the clamping plate 412, one end of the transmission rod 44 is pulled through the second docking rod 45, so that the transmission rod 44 rotates at the hinge with the support frame 1, and the upper end of the transmission rod 44 pushes the convex plate 41 to move upward and protrude above the top of the support frame 1. At this time, the transmission box girder 31 is limited inside the support frame 1 by the clamping plate 412 being clamped inside the card slot 48, avoiding the rapid reset of the transmission box girder 31, thus ensuring that the elastic waves generated by the metal semi-circular part 37 have enough propagation time, and further improving the monitoring effect of the hollow situation of the high slope of the road; While the vehicles on the road keep moving, the rear wheels will press down on the convex plate 41, reversely push the transmission rod 44 to rotate, and pull the clamping plate 412 to move reversely to compress the second elastic piece 47, disengaging from the inside of the clamping groove 48. At this time, the transmission box girder 31 loses its limit, and the reset protrusion is higher than the top of the support frame 1 under the action of the first elastic piece 322. At the same time, the first magnet 34 contacts the second magnet 39, and then the elastic wave generated by the next moving vehicle pressing down on the downward pressure monitoring assembly 3 can be used to monitor the high slope of the road. In this way, the real-time monitoring of the high slope of the road can be realized reciprocally.
