Description

Technical Field

[0001] This utility model relates to the field of slope monitoring technology, specifically to a highway slope displacement monitoring and early warning device. Background Technology

[0002] During road construction, the heterogeneity of strata and rock properties can easily lead to the formation of cracks in high slopes. These cracks can endanger the safety of surrounding residents, facilities, and roads, requiring long-term monitoring to understand their development and stability, providing a scientific basis for subsequent remediation. Traditional slope displacement monitoring devices typically consist only of displacement sensors, GNSS components, and other measurement and transmission units. Their high concealment after installation makes direct observation difficult. When monitoring data exceeds the warning threshold, the device immediately transmits data and triggers an warning. Subsequently, the operating unit must assess slope stability based on deformation characteristics and formulate corresponding control measures. However, for sudden emergencies such as landslides induced by short-term heavy rainfall, the existing process involves data transmission, warning issuance, manual judgment, and control decision-making, resulting in a lengthy response chain. This could lead to secondary risks for vehicles and personnel after road closures, exposing the deficiency of traditional monitoring devices in their lack of disaster early warning capabilities.

[0003] In addition, the monitoring devices are easily obscured by vegetation after installation, reducing visibility and making it difficult for designers to conduct follow-up investigations. At the same time, the devices are highly specialized and difficult for pedestrians to identify, resulting in a lack of safety judgment when faced with potential landslide hazards, further exacerbating safety risks. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention aims to provide a highway slope displacement monitoring and early warning device. This solution can receive and transmit data on changes in local stress by measuring the displacement at both ends of the arc-shaped sensing rod. After data analysis and processing, it can be linked to a visual warning unit, which can quickly alert pedestrians or vehicles while also facilitating the location of monitoring points for professionals.

[0005] This utility model is achieved through the following technical solution:

[0006] A highway slope displacement monitoring and early warning device, comprising:

[0007] The base is anchored to a stable slope on one side of the crack by a first fixed column;

[0008] A fixing block, which is anchored to the other side of the crack by a second fixing post;

[0009] An arc-shaped sensing rod, the two ends of which are respectively connected to the base and the fixing block, and the middle part of the arc-shaped sensing rod is bent away from the slope.

[0010] The arc-shaped sensing rod is hollow inside, and several elastic deformation force sensors are arranged sequentially along its length inside the arc-shaped sensing rod; the arc-shaped sensing rod is also equipped with a visual warning unit.

[0011] Compared to existing technologies, which suffer from drawbacks such as difficulty in observing vegetation growth after installation on the road, hindering follow-up surveys by designers, and the specialized nature of monitoring devices leaving pedestrians with limited knowledge and the inability to assess potential landslides or other emergencies, this invention provides a highway slope displacement monitoring and early warning device. This solution receives and transmits data on changes in local stress by detecting displacement at both ends of an arc-shaped sensing rod. After data analysis and processing, it is linked to a visual warning unit, quickly alerting pedestrians and vehicles while also facilitating the location of monitoring points for professionals. Specifically, the device includes a base installed on one side of the crack and a fixing block installed on the other side, with the base positioned on a stable slope. The arc-shaped sensing rod is hollow and contains several elastic deformation force sensors arranged sequentially along its length. The circular cross-section of the arc-shaped sensing rod provides wind resistance and a degree of rigidity, while the multiple elastic deformation force sensors offer high sensitivity in detecting slope displacement. When displacement deformation occurs on the other side of the slope crack, i.e., planar or longitudinal displacement, the arc-shaped sensing rod itself undergoes local deformation. Each elastic deformation force sensor transmits deformation data back to the data processing center. Based on the comparison with preset data, the real-time shape of the arc-shaped sensing rod can be determined. By observing the deformation of the arc-shaped sensing rod, the displacement of the monitoring point on site can be judged. When the threshold is exceeded, the visual warning unit is controlled to issue a visual warning, thus facilitating the warning of passing vehicles. The arc-shaped sensing rod bends away from the slope surface, preferably forming an arch perpendicular to the slope surface. This way, installing the visual warning unit on the arc-shaped sensing rod can avoid obstruction by later-grown vegetation. Therefore, the above scheme not only enables pedestrians or vehicles to make safe judgments about possible landslides and other sudden dangers, but also facilitates follow-up investigations by designers.

[0012] In addition, if the distance between the base and the fixed block is far, the curvature of the arc-shaped sensing rod can be appropriately reduced in order to ensure sensitivity, control costs, and reduce wind resistance.

[0013] A further improvement, to facilitate the monitoring of multiple cracks, includes several mounting blocks on the base, each corresponding to a fixing block and connected by an arc-shaped sensing rod. Preferably, one base corresponds to two arc-shaped sensing rods, and through a triangular fixing method, the displacement of multiple slope cracks can be monitored more accurately.

[0014] A further proposed solution involves anchoring the first fixed column into the ground, with a first fixed rod at the bottom that can extend into the ground, and a second fixed column at the bottom that can extend into the ground.

[0015] A further step in the design involves installing humidity sensors on both the first and second fixed poles to monitor soil moisture changes at different depths, as rainfall is a significant factor contributing to slope landslides. These sensors monitor the moisture levels at different depths of the soil where rainfall penetrates, helping to assess the impact of rainfall on slope stability. Increased soil moisture can reduce the soil's bearing capacity, thus increasing the risk of landslides. Monitoring humidity allows for the timely detection of abnormal soil moisture levels, enabling preventative measures to be taken in advance. When the humidity sensors detect soil moisture reaching or exceeding a certain threshold, they can issue an early warning signal, indicating a potential landslide risk and providing time for relevant personnel to implement emergency measures.

[0016] A further proposed solution, to create multiple warning effects, includes a visual warning unit comprising a plurality of LED beads arranged sequentially along the length of the arc-shaped sensing rod, each LED bead emitting a light source of several colors. In this solution, the data processing center can pre-set two warning thresholds: one is a preventative threshold where slope displacement and deformation affect slope stability but do not reach the level for sudden overall failure; the other is a pre-disaster threshold where short-term force majeure causes sudden and destructive overall instability of the slope. The preventative threshold is consistent with the monitoring and warning systems of conventional slope displacement monitoring devices; at the time of warning, the slope has not yet experienced overall destructive instability, allowing for pre-reinforcement and protection to ensure normal highway operation. The pre-disaster threshold indicates that the slope is about to experience overall and destructive instability, requiring localized highway control to prevent unnecessary casualties. Thus, the LED beads can be controlled to emit different colors of light and flash according to the preventative and pre-disaster thresholds.

[0017] A further improvement is that, in order to provide power to several sensors, LEDs and other electrical devices, a column is also provided on the base, and a solar panel is fixed on the column.

[0018] A further enhancement to the warning effect is the installation of a loudspeaker on the pillar. This loudspeaker can be intelligently controlled to emit a sound, providing a dual warning through both visual and auditory means.

[0019] A further improvement is that, for ease of transportation and installation, the column and the base are detachably connected.

[0020] In a further embodiment, as a detachable connection, the base has a fixing ring seat, and the inner side of the fixing ring seat and the lower end of the column have matching threads.

[0021] In a further embodiment, both the base and the fixing block are equipped with acceleration sensors. Considering the complex environment of highway slopes, this solution adds acceleration sensors to the base and fixing block to detect slope vibration, displacement, and deformation. By filtering the collected data from the acceleration and elastic deformation force sensors to remove noise and interference, the data purity is improved. Machine learning algorithms (such as neural networks and support vector machines) are used to fuse and analyze the data from the two sensors. Through model training, the system can automatically learn and adapt to different slope environments, improving the intelligence level of early warning.

[0022] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0023] 1. This utility model provides a highway slope displacement monitoring and early warning device. Using this solution, the device can receive and send data on the change of local stress by measuring the displacement of the two ends of the arc-shaped sensing rod. After data analysis and processing, the device can be linked to a visual warning unit to avoid being blocked by vegetation. This device can quickly warn pedestrians or vehicles while also making it easier for professionals to locate the monitoring points.

[0024] 2. This utility model provides a highway slope displacement monitoring and early warning device. Using this solution, multiple cracks can be monitored. By comparing the collected data with the built-in data model, slope displacement can be observed and predicted, improving monitoring efficiency and providing accurate data support for designers. It is easy to operate, has a high degree of automation, and can automatically collect, transmit, and analyze data.

[0025] 3. This utility model provides a highway slope displacement monitoring and early warning device. Using this design, the arc-shaped sensing rod has high sensitivity. Multiple elastic deformation force sensors work together, and the data is imported into a data model to capture slope anomalies. The elastic deformation force sensors detect changes in force caused by displacement, while the acceleration sensors detect slope vibration and acceleration changes. Through data fusion, the slope displacement can be determined more accurately. A humidity sensor provides soil moisture data, increasing the ability to predict extreme rainy weather. The monitoring and early warning system of this invention can significantly reduce safety risks caused by slope instability, ensuring the safety of personnel and property.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0033] Example:

[0034] This embodiment provides a highway slope displacement monitoring and early warning device, such as... Figures 1-3 As shown, it includes:

[0035] Base 1, which is anchored to a stable slope on one side of crack 4 by a first fixing column 11;

[0036] Fixing block 2, which is anchored to the other side of crack 4 by second fixing post 21;

[0037] An arc-shaped sensing rod 3, the two ends of which are connected to the base 1 and the fixing block 2 respectively, and the middle part of the arc-shaped sensing rod 3 is bent away from the slope.

[0038] The arc-shaped sensing rod 3 is hollow inside, and several elastic deformation force sensors are arranged sequentially along its length inside the arc-shaped sensing rod 3; and the arc-shaped sensing rod 3 is also equipped with a visual warning unit.

[0039] Compared to existing technologies, which are difficult to observe on the road after vegetation growth and installation, hindering follow-up investigations by designers, and whose monitoring devices are often unfamiliar to pedestrians, this invention provides a highway slope displacement monitoring and early warning device. This solution uses the displacement of the two ends of the arc-shaped sensing rod 3 to receive and transmit data on changes in local stress. After data analysis and processing, it is linked to a visual warning unit, quickly alerting pedestrians and vehicles while also facilitating the location of monitoring points for professionals. Specifically, the device includes a base 1 installed on one side of the crack 4 and a fixing block 2 installed on the other side. The base 1 is positioned on a stable slope. The arc-shaped sensing rod 3 is hollow and has several elastic deformation force sensors arranged sequentially along its length. The circular cross-section of the arc-shaped sensing rod 3 provides wind resistance and rigidity, and the multiple elastic deformation force sensors offer high sensitivity in detecting slope displacement. When displacement deformation occurs on the other side of the slope crack 4, i.e., planar or longitudinal displacement, the arc-shaped sensing rod 3 itself undergoes local deformation. Each elastic deformation force sensor transmits deformation data back to the data processing center. Based on the comparison with preset data, the real-time shape of the arc-shaped sensing rod 3 can be obtained. By observing the deformation of the arc-shaped sensing rod 3, the displacement of the monitoring point on site can be determined. When the threshold is exceeded, the visual warning unit is controlled to issue a visual warning, thereby facilitating the warning of passing vehicles. The arc-shaped sensing rod 3 bends away from the slope surface, preferably in an arch shape perpendicular to the slope surface. This way, installing the visual warning unit on the arc-shaped sensing rod 3 can avoid obstruction by later-grown vegetation. Therefore, the above scheme not only enables pedestrians or vehicles to make safe judgments about possible landslides and other sudden dangers, but also facilitates follow-up investigations by designers.

[0040] In addition, if the distance between the base 1 and the fixing block 2 is far, the curvature of the arc-shaped sensing rod 3 can be appropriately reduced in order to ensure sensitivity, control costs, and reduce wind resistance.

[0041] In some embodiments, to facilitate the monitoring of multiple cracks 4, the base 1 is equipped with several mounting blocks 16, each mounting block 16 corresponding to a fixing block 2 and connected by an arc-shaped sensing rod 3. Preferably, one base 1 corresponds to two arc-shaped sensing rods 3, and the displacement of multiple slope cracks can be monitored more accurately through a triangular fixing method.

[0042] In some embodiments, for anchoring into the strata, the bottom of the first fixing post 11 is equipped with a first fixing rod 12 that can extend into the strata; the bottom of the second fixing post 21 is equipped with a second fixing rod that can extend into the strata.

[0043] In some embodiments, since rainfall is a significant factor contributing to slope landslides, humidity sensors are also installed on the first and second fixed rods to monitor soil moisture changes at different depths on the slope in real time. By installing multiple humidity sensors, the moisture content of the soil at different depths after rainfall infiltration can be monitored, helping to assess the impact of rainfall on slope stability. Increased soil moisture may reduce the soil's bearing capacity, thereby increasing the risk of slope landslides. Monitoring humidity allows for the timely detection of abnormal soil moisture, enabling preventative measures to be taken in advance. When the humidity sensor detects that the soil moisture reaches or exceeds a certain critical value, it can issue an early warning signal, indicating a potential landslide risk and providing time for relevant personnel to take emergency measures.

[0044] In some embodiments, to create multiple warning effects, the visual warning unit includes a plurality of LED beads 31 arranged sequentially along the length of the arc-shaped sensing rod 3, each LED bead 31 having a light source of several colors. In this scheme, the data processing center can preset two warning thresholds: one is a preventative threshold where slope displacement and deformation affect slope stability but do not reach the level for sudden overall failure; the other is a threshold for sudden, destructive overall instability of the slope due to short-term force majeure, i.e., a catastrophic threshold. The preventative threshold is consistent with the monitoring and warning of conventional slope displacement monitoring devices; at the time of warning, the slope has not yet experienced overall destructive instability, allowing for pre-reinforcement and protection to ensure normal highway operation. The catastrophic threshold is when the slope is about to experience overall, destructive instability, requiring localized highway control to prevent unnecessary casualties. Thus, for the preventative and catastrophic thresholds, the LED beads 31 can be controlled to emit different colors of light and flash.

[0045] In some embodiments, in order to provide power to several sensors, lamp beads 31 and other electrical devices, a column 15 is also provided on the base 1, and a solar panel 14 is fixed on the column 15.

[0046] In some embodiments, to enhance the warning effect, a horn 13 is also fixed on the column 15. The horn 13 can be intelligently controlled to emit a sound, achieving a dual warning through simultaneous visual and auditory perception.

[0047] In some embodiments, the column 15 and the base 1 are detachably connected for ease of transportation and installation.

[0048] In some embodiments, as a specific implementation of a detachable connection, the base 1 is provided with a fixing ring seat 17, and the inner side of the fixing ring seat 17 and the lower end of the column 15 are provided with matching threads.

[0049] In some embodiments, both the base 1 and the fixing block 2 are equipped with acceleration sensors. In this solution, considering the complex environment of highway slopes, acceleration sensors can be added to the base 1 and the fixing block 2 to sense the vibration, displacement, and deformation of the slope. By filtering the collected data from the acceleration sensor and the elastic deformation force sensor, noise and interference are removed, improving the data purity. Machine learning algorithms (such as neural networks and support vector machines) are used to fuse and analyze the data from the two sensors. Through model training, the system can automatically learn and adapt to different slope environments, improving the intelligence level of early warning.

[0050] How this solution works:

[0051] Locate the slope to be monitored. Dig a pit on the stable slope on one side of crack 4 and bury the first fixing column 11 of base 1, with base 1 exposed on the slope surface. Dig a pit to the same depth on the other side of crack 4 and bury the second fixing column 21, with the exposed part of fixing block 2 at the same height as base 1. Then install the arc-shaped sensing rod 3 and fix it to the top of base 1 and fixing block 2 respectively. Finally, fix column 15 to base 1. When displacement deformation occurs on the other side of slope crack 4, i.e., planar or longitudinal displacement, the arc-shaped sensing rod 3 itself will locally deform, causing each elastic deformation force sensor to transmit deformation data back to the data processing center, and determine the early warning mode according to the preset preventive threshold and disaster threshold. Under normal circumstances, the control light 31 flashes green (once every hour), indicating that the monitored displacement data is within the normal range. When the detected data reaches the preventive threshold, the control light 31 flashes yellow (once every 10 minutes), at which point the slope stability can be improved through reinforcement and protection measures. When the detected data reaches the critical disaster threshold, the control light 31 flashes red (once every 2 seconds), and the horn 13 sounds an alarm (once every 10 seconds), warning vehicles passing through the section to observe before proceeding or to stop.

[0052] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
