Description

Technical Field

[0001] This utility model relates to the field of bridge monitoring technology, specifically a bridge deformation monitoring device. Background Technology

[0002] As is well known, the scale and complexity of existing bridge projects are constantly increasing, and structural deformation problems caused by factors such as load, environmental corrosion, and material aging are becoming increasingly prominent during the long-term service of bridges.

[0003] Traditional bridge deformation monitoring methods rely heavily on manual inspections and static measurement equipment, such as total stations and levels, which have limitations such as low monitoring frequency, poor real-time performance, and high labor costs.

[0004] In recent years, automated monitoring technologies have become increasingly popular, such as monitoring devices based on fiber optic gratings, tilt sensors, or GPS positioning. However, the fixed installation positions of the sensors make it impossible to dynamically adjust the monitoring angle and coverage according to the deformation characteristics of the bridge. At the same time, a single sensor type may lead to biased data and make it impossible to comprehensively assess the overall deformation status of the bridge. In addition, most devices rely on wired power supply or frequent battery replacements, making operation and maintenance difficult in remote areas or harsh environments. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a bridge deformation monitoring device.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, the present invention provides the following technical solution: a bridge deformation monitoring device, comprising a monitoring host, with adjustment components at both the upper and lower ends of the monitoring host, and a deformation monitor and a distance monitor mounted on the adjustment components, both of which are signal-connected to the monitoring host, a fixing component at the rear end of the monitoring host, and a battery component providing power on one side of the monitoring host.

[0009] To achieve flexible adjustment of the deformation monitor and distance monitor at multiple angles, this utility model improves upon the following: the adjustment assembly includes a limiting plate, a motor, and a rotating column. The limiting plates are arranged symmetrically in two sets on both sides of the monitoring host. The rotating column passes through the limiting plate. The motor is located on one side of the limiting plate. One end of the rotating column is connected to the output end of the motor. The deformation monitor is connected to the upper rotating column, and the distance monitor is connected to the lower rotating column.

[0010] In order to adapt to the installation requirements of different bridge surfaces (such as concrete and steel structures), the present invention has the following improvements: the fixing component includes a fixing plate and a limiting nail, the fixing plate is located on the rear side of the monitoring host, and the limiting nail passes through the four corners of the fixing plate.

[0011] To achieve off-grid power supply, the present invention is improved as follows: the battery assembly includes a support plate, a photovoltaic panel and a storage battery, the support plate is connected to one side of the monitoring host, the photovoltaic panel is on the side wall of the support plate, and the storage battery is on the rear side of the photovoltaic panel.

[0012] To directly alert bridge inspectors or nearby vehicles, this utility model is improved by installing alarm lights and alarm horns on both sides of the monitoring host.

[0013] To avoid monitoring interruption due to power failure, the present invention is improved by equipping the battery with a power detection chip, which automatically sends a "low power warning" text message to the administrator's mobile phone when the power level is below 20%.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a bridge deformation monitoring device, which has the following features:

[0018] Beneficial effects:

[0019] This bridge deformation monitoring device is equipped with a deformation monitor and a distance monitor, enabling simultaneous detection of bridge structural deformation (such as bending and stretching) and displacement changes. The dual-core processor processes the two types of sensor data separately. The deformation core focuses on real-time calculation, while the other core quickly matches historical records through a data comparison library. Combined with the cloud upload function, it can identify instantaneous anomalies (such as sudden cracks) and capture long-term deformation trends, significantly improving the comprehensiveness and reliability of the monitoring results.

[0020] Equipped with an adjustment component and featuring a motor-driven rotating column design, the sensor can automatically adjust its monitoring angle according to the bridge's deformation characteristics, expanding the coverage area and avoiding blind spots found in fixed sensors.

[0030] Please see Figure 1-4A bridge deformation monitoring device includes a monitoring host 5. Adjustment components are provided at both the upper and lower ends of the monitoring host 5. A deformation monitor 3 and a distance monitor 4 are mounted on the adjustment components. Both the deformation monitor 3 and the distance monitor 4 are signal-connected to the monitoring host 5. A fixing component is provided at the rear end of the monitoring host 5. A battery assembly providing power is provided on one side of the monitoring host 5. The battery assembly includes a support plate 10, a photovoltaic panel 11, and a storage battery 13. The support plate 10 is connected to one side of the monitoring host 5. The photovoltaic panel 11 is located on the upper side wall of the support plate 10, and the storage battery 13 is located behind the photovoltaic panel 11. An alarm light 12 and an alarm horn 6 are respectively provided on both sides of the monitoring host 5. The monitoring host 5 has a built-in wireless communication module, and the monitoring data is uploaded to the cloud in real time. The monitoring host 5 has a dual-core processor and a data comparison library inside, and its outer shell is made of waterproof material.

[0031] During use, the device is fixed to one end of the bridge bottom (such as a pier or beam monitoring point) via a rear-end fixing component. Then, the adjustment component is activated, causing the deformation monitor 3 and distance monitor 4 to adjust their initial monitoring angles, covering key areas of the bridge (such as beam joints and support points) to form a multi-directional monitoring layout. The deformation monitor 3 (laser scanner) performs high-frequency scanning or real-time image acquisition on the bridge surface, identifying bending, torsion, or localized cracking of the bridge structure by measuring displacement, strain, or crack propagation parameters. The adjustment component adjusts the tilt angle and scanning range of the deformation monitor 3 according to a preset program or real-time feedback (e.g., focusing on areas with abnormal deformation). This ensures accurate monitoring of the bridge. The system comprehensively monitors the overall deformation of the bridge beam. Monitoring data is transmitted in real-time to the monitoring host 5 via wired or wireless signals. Simultaneously, the distance monitor 4 (ultrasonic sensor) continuously measures the vertical distance between the bridge's bottom and the ground or water surface. Through periodic data acquisition (e.g., 10 times per second), it tracks the bridge's settlement or overall downward movement trend in real time and transmits the data to a dual-core processor. The dual-core processor performs the following tasks: Core 1 quickly analyzes the raw data from the deformation monitor 3 (such as displacement and crack width), compares it with preset safety thresholds or historical records in the data comparison database, and determines whether it exceeds the allowable range. Core 2 synchronously processes the data from the distance monitor 4 and coordinates the data interaction between the wireless communication module and the cloud. This dual-core processing... The device compares the current data with baseline values ​​in the data comparison database (such as the distance recorded during initial installation). When an abnormally shortened distance value is detected (such as bridge subsidence due to pier settlement), the monitoring host 5 immediately initiates the anomaly judgment process. If the distance exceeds the limit multiple times consecutively or the rate of change is abnormal, it is judged as a displacement risk, triggering the alarm mechanism. The monitoring host 5 emits audible and visual warnings through the alarm lights 12 (high-brightness LEDs) on both sides and the alarm horn 6 (high-frequency buzzer) to remind inspection personnel or surrounding vehicles to take emergency evasive action. At the same time, the built-in wireless communication module uploads the abnormal data (including deformation parameters, displacement, and timestamps) to the cloud server in real time. Management personnel can view the data via mobile phone or computer terminal. The system displays real-time data curves, receives early warning notifications, and remotely dispatches maintenance teams. During monitoring, the photovoltaic panels 11 on the support plate 10 convert solar energy into electrical energy and store it in the battery 13 at the rear, providing continuous power to the monitoring host 5, sensors, communication modules, etc. The waterproof casing of the monitoring host 5 (such as IP67 rating) isolates rainwater and moisture from intrusion, protecting the internal electronic components to operate stably for a long time in humid environments (such as bridges near water). The dual-core processor, combined with the data comparison library, filters noise data caused by environmental interference (such as vehicle vibration and temperature fluctuations) to avoid false alarms (for example, short-term distance fluctuations may be caused by water waves, and the system eliminates interference through continuous data verification).

[0032] In practical use, it is necessary to achieve flexible adjustment of the deformation monitor 3 and the distance monitor 4 at multiple angles to expand the monitoring range. To meet the above requirements, in this embodiment, the adjustment assembly includes a limiting plate 8, a motor 7, and a rotating column 9. The limiting plates 8 are arranged symmetrically in two sets on both sides of the monitoring host 5. The rotating column 9 passes through the limiting plate 8. The motor 7 is located on one side of the limiting plate 8. One end of the rotating column 9 is connected to the output end of the motor 7. The deformation monitor 3 is connected to the upper rotating column 9, and the distance monitor 4 is connected to the lower rotating column 9.

[0033] After receiving the command from the monitoring host 5, the motor 7 of the adjustment component starts and drives the rotating column 9 to rotate around the axis. Since the rotating column 9 passes through the symmetrically arranged limiting plates 8, its movement trajectory is precisely limited to avoid deviation or shaking and ensure adjustment stability. The deformation monitor 3 (installed on the upper rotating column 9) adjusts the scanning angle by rotating to cover key areas such as bridge beams and joints; the distance monitor 4 (installed on the lower rotating column 9) adjusts the pitch angle by vertical rotation to align with the bottom of the bridge pier or the target point on the water / ground surface.

[0034] In practical use, it is necessary to adapt to the installation requirements of different bridge surfaces (such as concrete and steel structures) and simplify on-site construction steps. To meet the above requirements, in this embodiment, the fixing component includes a fixing plate 1 and limiting nails 2. The fixing plate 1 is located on the rear side of the monitoring host 5, and the limiting nails 2 penetrate through the four corners of the fixing plate 1.

[0035] During installation, the limiting pin 2 penetrates the fixing plate 1 and is embedded in the bridge surface (pre-drilled hole in concrete or steel structure) to ensure that the device remains stable under vibration, wind or vehicle traffic impact.

[0036] In actual use, it is necessary to avoid monitoring interruption due to power failure and extend the unattended operation period of the equipment. In order to meet the above requirements, in this embodiment, the battery 13 is equipped with a power detection chip. When the power is lower than 20%, it automatically sends a "low power warning" text message to the administrator's mobile phone.
