Description

Technical Field

[0001] This utility model relates to the field of bridge engineering structure monitoring technology, and in particular to a bridge engineering bearing capacity monitoring device. Background Technology

[0002] In modern transportation networks, bridges, as critical infrastructure, bear immense pressure on transportation. With accelerating urbanization and continuously increasing traffic volume, especially the frequent passage of heavy vehicles, the service environment for bridges is becoming increasingly demanding. Furthermore, many early-built bridges, limited by the design concepts, material quality, and construction techniques of their time, generally had lower design load ratings. Coupled with long-term exposure to the natural environment, including wind and rain erosion, temperature changes, and earthquakes, bridge structures inevitably experience aging and damage, leading to a gradual decline in their load-bearing capacity and posing serious challenges to their safety performance.

[0003] When existing technical solutions are used,

[0004] (1) Its sensor arrangement is relatively simple, and it can only monitor the stress data of a single dimension of the bridge. It cannot fully reflect the actual bearing capacity of the bridge under complex load conditions, and it is difficult to meet the needs of refined bridge monitoring.

[0005] (2) The data processing and transmission module has a low degree of integration. During the data transmission process, it is easily affected by external electromagnetic interference, which leads to a decrease in the accuracy of monitoring data. The bridge will generate continuous vibration when vehicles pass by. There is a lack of effective vibration reduction and data stabilization mechanisms. The vibration will further interfere with the accurate measurement of the sensor, which will increase the error of the detection data. It does not have a real-time early warning function and cannot issue an alarm in time when the bridge bearing capacity is abnormal.

[0006] To address the aforementioned problems, this utility model provides a bridge engineering bearing capacity monitoring device. Utility Model Content

[0007] The purpose of this invention is to solve the problems of existing technologies, such as the single sensor arrangement, inability to comprehensively and accurately monitor bridge bearing capacity and provide real-time early warning, and susceptibility to bridge vibration interference, and to propose a bridge engineering bearing capacity monitoring device.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a bridge engineering bearing capacity monitoring device, comprising a connecting plate, a pressure detection mechanism, a displacement detection mechanism, a data collection and processing mechanism, and a fixed connection mechanism. The pressure detection mechanism is threadedly connected to the middle of the bottom of the connecting plate, the displacement detection mechanism is threadedly connected to both ends of the bottom of the connecting plate, the data collection and processing mechanism is threadedly connected to the bottom of the connecting plate, the pressure detection mechanism includes a fixed plate threadedly connected to the bottom of the connecting plate, bolts threadedly connected to both sides of the fixed plate, a pressure sensor fixedly connected to the bottom of the fixed plate, an alarm generator fixedly connected to the top of the pressure sensor, and a controller fixedly connected to the outer surface of the pressure sensor.

[0009] Furthermore, the pressure sensor is located at the support point of the main beam of the bridge, and the pressure sensor is symmetrically arranged at both ends of the connecting plate.

[0010] Furthermore, the displacement detection mechanism includes a vertical laser displacement sensor threadedly connected to the center of the bottom of the connecting plate, and a horizontal laser displacement sensor threadedly connected to both sides of the connecting plate. A data connection line is fixedly connected between the vertical laser displacement sensor and the horizontal laser displacement sensor.

[0011] Furthermore, the lateral laser displacement sensor and the vertical laser displacement sensor are installed at the bottom and sides of the main beam of the bridge. The lateral laser displacement sensor is symmetrically arranged on both sides of the connecting plate, and an alarm generator is fixedly connected to the top of the vertical laser displacement sensor and the lateral laser displacement sensor.

[0012] Furthermore, the data collection and processing mechanism includes two data processing collectors fixedly connected to the bottom of the connecting plate. A dustproof net is fixedly connected to the top of each data processing collector. The data processing collectors are symmetrically arranged on both sides of the displacement detection mechanism. The pressure detection mechanism, the displacement detection mechanism, and the data collection and processing mechanism are interconnected by a data connection line.

[0013] Furthermore, the fixed connection mechanism includes a damper located on the top of the connecting plate, with connecting parts threaded to both sides of the damper, a shock-absorbing telescopic spring sleeved on the outer surface of the damper, and an anti-slip plate fixedly connected to the top of the damper and the shock-absorbing telescopic spring.

[0014] Furthermore, the fixed connection mechanism includes bridge surface connectors threaded to both sides of the connecting plate, and anti-slip strips are fixedly connected to the inner wall of the connecting plate.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, by setting up vertical laser displacement sensors, horizontal laser displacement sensors, and pressure sensors, the vertical and horizontal laser displacement sensors monitor the vertical and horizontal displacement changes of the bridge in real time and accurately, while the pressure sensors accurately measure the pressure at the bridge supports. These sensors work together to comprehensively and meticulously reflect the actual bearing capacity of the bridge under complex loads. At the same time, the alarm generators set on the top of each sensor can quickly issue alarms when the monitoring data is abnormal, enabling staff to detect potential safety hazards of the bridge at the first time and take effective countermeasures such as restricting traffic flow and carrying out bridge maintenance and reinforcement, which greatly improves the safety of bridge operation.

[0017] 2. In this utility model, the reliability of data processing and the stability of the monitoring device installation are significantly improved by setting up a data processing acquisition unit, a shock-absorbing telescopic spring, and an anti-slip plate. The data processing acquisition unit can efficiently and stably process multi-source monitoring data. Its built-in advanced data processing algorithm can accurately calculate the bridge bearing capacity and realize real-time and stable data transmission through a wireless communication module, ensuring the accuracy and timeliness of monitoring data. The synergistic effect of the shock-absorbing telescopic spring and the anti-slip plate effectively suppresses the impact of bridge vibration on the monitoring device. The shock-absorbing telescopic spring absorbs vibration energy and reduces the vibration amplitude of the device, while the anti-slip plate increases the friction with the bridge surface, preventing device displacement and ensuring high accuracy of sensor measurement, thereby improving the long-term stability and reliability of the device.

Detailed Implementation

[0026] Please see Figure 1-6 This utility model provides a technical solution: a bridge engineering bearing capacity monitoring device, including a connecting plate 1, a pressure detection mechanism 2, a displacement detection mechanism 3, a data collection and processing mechanism 4, and a fixed connection mechanism 5. The pressure detection mechanism 2 is threaded to the middle of the bottom of the connecting plate 1, the displacement detection mechanism 3 is threaded to both ends of the bottom of the connecting plate 1, and the data collection and processing mechanism 4 is threaded to the bottom of the connecting plate 1.

[0027] The following section will describe in detail the specific setup and function of its pressure detection mechanism 2, displacement detection mechanism 3, data collection and processing mechanism 4, and fixed connection mechanism 5.

[0028] In this embodiment: the pressure detection mechanism 2 includes a fixing plate 21 threaded to the bottom of the connecting plate 1, bolts 22 threaded to both sides of the fixing plate 21, a pressure sensor 23 fixedly connected to the bottom of the fixing plate 21, an alarm generator 24 fixedly connected to the top of the pressure sensor 23, and a controller 25 fixedly connected to the outer surface of the pressure sensor 23.

[0029] The effect achieved by the above components is as follows: The pressure sensor 23 fixed at the bottom of the fixing plate 21 is a high-precision strain gauge pressure sensor 23, which has extremely high sensitivity and can accurately measure the pressure change at the support point of the main beam of the bridge. When the pressure value monitored by the pressure sensor 23 exceeds the preset safety threshold, the alarm generator 24 on the top is immediately activated and emits a loud audible and visual alarm signal to notify the bridge management department to pay attention to the abnormal stress of the bridge in a timely manner.

[0030] Specifically, the pressure sensor 23 is located at the support point of the main beam of the bridge, and the pressure sensor 23 is symmetrically arranged at both ends of the connecting plate 1.

[0031] The effect achieved by the above components is that the pressure sensors 23, which are symmetrically arranged on both sides at the bottom of the connecting plate 1, can simultaneously monitor the pressure status on both sides of the main beam support of the bridge. By comparing the data on both sides, it can be determined whether the bridge is in a balanced state under load.

[0032] Specifically, the displacement detection mechanism 3 includes a vertical laser displacement sensor 31 threadedly connected to the middle of the bottom of the connecting plate 1, and a horizontal laser displacement sensor 32 threadedly connected to both sides of the connecting plate 1. A data connection line 33 is fixedly connected between the vertical laser displacement sensor 31 and the horizontal laser displacement sensor 32.

[0033] The effects achieved by the above components are as follows: the vertical laser displacement sensor 31 is mainly used to monitor the displacement changes of the main beam of the bridge in the vertical direction in real time, and can accurately capture the settlement displacement of the bridge caused by factors such as its own weight and vehicle load. The horizontal laser displacement sensor 32 focuses on monitoring the horizontal displacement of the bridge, and can detect the horizontal sway of the bridge caused by factors such as wind force and vehicle eccentricity in a timely manner.

[0034] Specifically, the lateral laser displacement sensor 32 and the vertical laser displacement sensor 31 are installed at the bottom and side of the main beam of the bridge. The lateral laser displacement sensor 32 is symmetrically arranged on both sides of the connecting plate 1. An alarm generator 24 is fixedly connected to the top of the vertical laser displacement sensor 31 and the lateral laser displacement sensor 32.

[0035] The effect achieved by the above components is as follows: the horizontal laser displacement sensor 32 is symmetrically arranged on both sides of the connecting plate 1, and is installed at the bottom and side of the main beam of the bridge along with the vertical laser displacement sensor 31, respectively. This fully covers the displacement monitoring needs of the bridge under common working conditions. When the monitored displacement exceeds the safe range, the alarm generator 24 at the top will immediately issue an alarm to remind the staff that there may be a risk of structural deformation of the bridge and that timely measures should be taken.

[0036] Specifically, the data collection and processing mechanism 4 includes a data processing collector 41 fixedly connected to the bottom of the connecting plate 1. There are two data processing collectors 41. A dustproof net 42 is fixedly connected to the top of the data processing collector 41. The data processing collectors 41 are symmetrically arranged on both sides of the displacement detection mechanism 3. The pressure detection mechanism 2, the displacement detection mechanism 3, and the data collection and processing mechanism 4 are interconnected through a data connection line 33.

[0037] The effects achieved by the above components are: greatly improving the reliability and stability of data processing and collection. Even if one of the data processing and acquisition units 41 fails, the other can still work normally, ensuring the continuity of monitoring data and preventing data loss due to equipment failure. The dust filter 42 effectively blocks dust and debris from entering the equipment, preventing short circuits or performance degradation of electronic components due to dust accumulation, and ensuring long-term stable operation of the equipment in harsh environments.

[0038] Specifically, the fixed connection mechanism 5 includes a damper 51 opened on the top of the connecting plate 1, with connecting parts 52 threaded to both sides of the damper 51, a shock-absorbing telescopic spring 53 sleeved on the outer surface of the damper 51, and an anti-slip plate 54 fixedly connected to the top of the damper 51 and the shock-absorbing telescopic spring 53.

[0039] The effect achieved by the above components is as follows: when the bridge vibrates, the shock-absorbing telescopic spring 53 quickly absorbs the vibration energy and buffers the impact of the vibration on the monitoring device through its own telescopic deformation, effectively reducing the impact of vibration on the sensor measurement accuracy and ensuring that the sensor can still accurately collect data in complex vibration environments.

[0040] Specifically, the fixed connection mechanism 5 includes bridge connectors 55 threaded to both sides of the connecting plate 1, and anti-slip strips 56 are fixedly connected to the inner wall of the connecting plate 1.

[0041] The effects achieved by the above components are as follows: the bridge deck connectors 55 with threads on both sides of the connecting plate 1 are made of high-strength, fatigue-resistant alloy material, ensuring a reliable connection between the monitoring device and the bridge structure. The anti-slip strips 56 fixed on the inner wall of the connecting plate 1 further enhance the connection stability between the monitoring device and the bridge surface, effectively preventing the device from sliding during installation and use, and providing a solid guarantee for the stable operation of the entire monitoring device.

[0042] Working principle: During normal bridge operation, the pressure sensor 23 of the pressure detection mechanism 2 continuously monitors the pressure changes at the support points of the main beam of the bridge and transmits the pressure data to the controller 25 for preprocessing. Then, it is transmitted to the data processing and acquisition unit 41 through the data connection line 33. The vertical laser displacement sensor 31 and the horizontal laser displacement sensor 32 of the displacement detection mechanism 3 capture the vertical and horizontal displacement data of the main beam of the bridge in real time, and transmit it to the data processing and acquisition unit 41 through the data connection line 33.

[0043] After receiving multi-source data from the pressure detection mechanism 2 and the displacement detection mechanism 3, the data processing and acquisition unit 41 uses the built-in algorithm to perform in-depth analysis and integration of the data, and accurately calculates the real-time bearing capacity of the bridge. During the calculation process, if the pressure value detected by the pressure sensor 23 or the displacement detected by the displacement sensor exceeds the preset safety threshold, the alarm generator 24 immediately issues an audible and visual alarm signal.

[0044] Meanwhile, the data processing and acquisition unit 41 transmits real-time load-bearing capacity data and alarm information to the remote monitoring center via the wireless communication module for bridge management personnel to view and analyze. Based on the received data and alarms, the management personnel can promptly assess the safety status of the bridge structure. If any abnormality is detected, corresponding measures can be taken immediately. Throughout the process, the fixed connection mechanism 5 works in concert with the damper 51, shock-absorbing telescopic spring 53, anti-slip plate 54, bridge deck connector 55, and anti-slip strip 56 to effectively reduce the impact of bridge vibration on the monitoring device, ensuring that the device is securely installed on the bridge and providing a stable working environment for the sensor to accurately collect data and for the stable transmission of data.
