Description

Technical Field

[0001] The present invention belongs to the technical field of civil engineering surveying, and particularly relates to a highway bridge settlement measurement device. Background Art

[0002] Highway bridges are structures erected over rivers, lakes, and seas to enable vehicles and pedestrians on the highway to pass smoothly. Under the long-term load, the foundation or structure of the highway bridge undergoes a vertical downward displacement, resulting in a decrease in the elevation of the bridge deck. In the short term, it will cause the bridge deck to be uneven, leading to vehicle jolts and jumps. In the long term, it may cause structural cracks, bearing voids, and even bridge collapses. Therefore, measurement devices are used to monitor the settlement of highway bridges in order to detect problems in a timely manner and handle them.

[0003] In the Chinese patent with the publication number CN218034997U, a highway bridge settlement detection device is mentioned. Through the mounting plate, connecting plate, protective box, hollow column, controller, pressure sensor, movable plate, spring, extension column, and support plate, it effectively realizes the automatic detection of the bridge sinking situation by the detection device, avoiding the need for operators to detect the bridge sinking situation at intervals, reducing the labor intensity of operators when detecting the bridge sinking situation, and improving the convenience during the use of the detection device. However, when this detection device is in use, it measures the settlement by detecting the pressure received by the pressure sensor. However, since the pressure sensor cannot distinguish the settlement from the pressure fluctuations caused by other factors (such as temperature changes, vehicle loads, bearing aging, etc.), relying solely on pressure data cannot cross-verify the authenticity of the settlement, which may lead to false alarms or missed alarms.

Detailed implementation manners

[0018] 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 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.

[0019] Embodiment 1:

[0020] Please refer to Figures 1 to 8 As shown, a highway bridge settlement measurement device includes: Mounting frame 1; One end of the mounting frame 1 is installed with a measuring mechanism 2, the other end of the mounting frame 1 is provided with an adjustment groove 3, an installation mechanism 4 is commonly installed between the inner walls on both sides of the adjustment groove 3, and a photovoltaic mechanism 5 is installed at the top of the mounting frame 1; The measuring mechanism 2 includes a protective box 21, a laser rangefinder 22, a displacement sensor 23, a telescopic frame 24, a support plate 25 and a pressure sensor 26. The protective box 21 is installed at one end of the mounting frame 1, the laser rangefinder 22 is installed at the lower part of one end of the protective box 21, the displacement sensor 23 is installed at the lower part of the other end of the protective box 21, the telescopic frame 24 is inserted and installed on the bottom inner wall of the protective box 21, the support plate 25 is installed at the bottom end of the telescopic frame 24, and the pressure sensor 26 is embedded at the bottom end of the support plate 25.

[0021] ByFigures 1 to 5 It can be seen that the bridge guardrail 6 is clamped and installed on the installation mechanism 4. The reinforcing plate 7 is installed on the top inner wall of the installation frame 1, and one end of the reinforcing plate 7 is installed at the other end of the measuring mechanism 2. The humidity and temperature sensor 8 is installed on one outer wall of the reinforcing plate 7, and the controller 9 is installed on the other outer wall of the reinforcing plate 7; The inclination sensor 27 is installed at the top of the protection box 21. The spring 28 is installed at the top of the telescopic frame 24, and the top of the spring 28 is installed on the top inner wall of the protection box 21. The distance measuring sensor 29 is installed in the middle of the top inner wall of the protection box 21.

[0022] As can be seen from the above, first, the installation mechanism 4 is installed on the bridge guardrail 6, and the support plate 25 is in contact with the road surface of the highway bridge. When the road surface of the highway bridge settles, the elastic force of the spring 28 is used to push the telescopic frame 24 downward, so that the support plate 25 drives the pressure sensor 26 to also move downward and always be in contact with the ground. At this time, the laser rangefinder 22 provides the absolute displacement reference value of the settlement. The displacement sensor 23 is used to measure and verify the relative displacement of the support plate 25, double-verifying the settlement amount and improving the reliability. The contact pressure between the support plate 25 and the road surface is monitored by the pressure sensor 26, and whether the support plate 25 continues to contact the road surface is verified according to the pressure data, so as to avoid false judgment of suspension. The inclination sensor 27 is used to monitor the change of the inclination angle of the device or the bridge, so as to distinguish settlement from inclination and avoid false judgment caused by angle change. At the same time, the distance measuring sensor 29 is used to detect the distance between itself and the telescopic frame 24, and then the settlement data is obtained. The humidity and temperature sensor 8 is used to monitor the environmental temperature and humidity in real time, so as to correct the environmental error in real time and ensure the accuracy of the data of each sensor. Multiple sensors all transmit the measurement data to the controller 9, and the controller 9 compares the received data. If the pressure is normal but the displacement is abnormal, the state of the laser rangefinder 22 or the support plate 25 needs to be checked. Through the collaborative work of multiple sensors, the real-time monitoring of the highway bridge can be realized. Specifically, by comprehensively analyzing the data of each sensor, the influence of settlement and other factors on the monitoring results can be distinguished, and the authenticity of the settlement can be cross-verified, avoiding false alarms or missed reports, thereby improving the detection accuracy and reliability of the measuring device.

[0023] Specifically, referring to Figures 1 to 5 As shown, the distance measuring sensor 29, the inclination sensor 27, the pressure sensor 26, the displacement sensor 23, the laser rangefinder 22 and the humidity and temperature sensor 8 are all electrically connected to the controller 9. The telescopic frame 24 is set as an I-shaped structure, and the installation frame 1 is set as an L-shaped structure.

[0024] As can be seen from the above, enabling various sensors to transmit the collected data signals such as distance, angle, pressure, displacement, temperature and humidity to the controller 9 in the form of electrical signals provides a basis for subsequent data processing, analysis and decision-making. The I-shaped structure has good stability and load-bearing capacity. This structural setting enables the telescopic frame 24 to remain relatively stable during the telescopic process and can withstand a certain external force at the same time. The L-shaped mounting frame 1 can bear the weight of the measuring mechanism 2 and the photovoltaic mechanism 5, avoiding structural deformation caused by vibration or wind force.

[0025] Embodiment 2:

[0026] Reference Figure 6 and Figure 7 As shown, the mounting mechanism 4 includes a fixed frame 41, an upper mounting component 42, a lower mounting component 43 and a driver 44. The fixed frame 41 is installed in the middle of the inner wall of the adjustment groove 3. The upper mounting component 42 is installed at the top of the fixed frame 41. The lower mounting component 43 is installed at the bottom of the fixed frame 41. The driver 44 is installed at the top of the upper mounting component 42; The upper mounting component 42 includes a left-right screw 421, an adjustment block 422, a mounting clamping plate 423 and a clamping groove 424. The left-right screw 421 is installed between the top inner wall of the adjustment groove 3 and the top of the fixed frame 41 through a bearing. There are two adjustment blocks 422, two mounting clamping plates 423 and two clamping grooves 424. The two adjustment blocks 422 are both installed on the outer surface of the left-right screw 421. The two mounting clamping plates 423 are respectively installed on the opposite surfaces of the two adjustment blocks 422. The two clamping grooves 424 are respectively opened on the opposite surfaces of the two mounting clamping plates 423.

[0027] As can be seen from the above, when installing this measuring device, first place the device near the bridge guardrail 6, and align the upper mounting component 42 and the lower mounting component 43 with the two cross bars on the bridge guardrail 6 respectively. Then, start through the controller 9, and the left-right screws 421 in the upper mounting component 42 and the left-right screws 421 in the lower mounting component 43 can be driven to rotate synchronously, so that the left-right screw 421 drives the two adjustment blocks 422 on it to move towards the middle, and drives the V-shaped clamping grooves 424 on the two mounting clamping plates 423 to clamp the cross bar on the bridge guardrail 6 together, so as to realize the firm installation of this measuring device and the bridge guardrail 6. Moreover, through the two-point installation of the upper mounting component 42 and the lower mounting component 43 with the two cross bars on the bridge guardrail 6, the firmness and stability during the installation of the measuring device are increased. Compared with single-point installation, two-point installation can better disperse the external force received by the device, reduce the shaking and displacement of the device caused by external force during operation, thereby improving the measurement accuracy and service life of the device, and ensuring that the device can operate stably and reliably for a long time.

[0028] Preferably, refer to Figure 6 and Figure 7As shown, the clamping groove 424 is set as a V-shaped structure. The overall structure of the upper mounting component 42 is the same as that of the lower mounting component 43. The driver 44 is electrically connected to the controller 9.

[0029] As can be seen from the above, the V-shaped clamping groove 424 can improve the accuracy and stability of clamping. At the same time, it can also meet the clamping requirements of objects with different diameters within a certain range. The opposite surfaces of the upper mounting component 42 and the lower mounting component 43 are mounted together, which is beneficial for the driver 44 to drive the upper mounting component 42 and the lower mounting component 43 to start synchronously at the same time, and realize the firm clamping and installation of the bridge guardrail 6 at the same time, enabling the controller 9 to send control signals to the driver 44.

[0030] Embodiment 3:

[0031] Refer to Figure 8 As shown, the photovoltaic mechanism 5 includes a support frame 51, a storage battery 52, a drive motor 53, a photovoltaic panel 54, and a sun tracker 55. The support frame 51 is installed at the top of the mounting frame 1. The storage battery 52 is installed between the lower parts of the inner walls on both sides of the support frame 51, and the bottom end of the storage battery 52 is installed at the top of the mounting frame 1. The drive motor 53 is installed at the upper part of one end of the support frame 51. The photovoltaic panel 54 is installed between the upper parts of the inner walls on both sides of the support frame 51 through a rotating shaft. There are two sun trackers 55, and the two sun trackers 55 are respectively installed on the outer walls on both sides of the photovoltaic panel 54.

[0032] As can be seen from the above, during use, the photovoltaic panel 54 can absorb solar energy and convert it into electrical energy, and then transmit the electrical energy to the storage battery 52 for storage. Then, the storage battery 52 can supply power to the entire measuring device, so that the measuring device does not require an external power supply during use, reducing the operation and maintenance cost of the device and effectively saving energy. At the same time, through the sun tracker 55, the position of the sun can be monitored, and the monitoring data is transmitted to the controller 9. The controller 9 starts the drive motor 53 according to the data, and the drive motor 53 drives the photovoltaic panel 54 to rotate to adjust the tilt angle of the photovoltaic panel 54, so that the photovoltaic panel 54 can be adjusted as the position of the sun changes. Through this dynamic adjustment method, the photovoltaic panel 54 can always maintain the best incident angle with the sun's rays, maximizing the absorption of sunlight, thereby improving the absorption and conversion efficiency of solar energy. In addition, this function of being able to adjust as the sun's position changes also greatly improves the power generation stability of the device under complex lighting conditions. Whether in the morning, at noon, or in the evening, whether the weather is sunny, cloudy, or overcast, the photovoltaic panel 54 can automatically adjust according to the actual position of the sun to ensure stable power generation under different lighting conditions and provide reliable power for the measuring device.

[0033] Preferably, refer to Figure 8As shown, the support frame 51 is set as an H-shaped structure. The drive motor 53 and the solar tracker 55 are both electrically connected to the controller 9, and the photovoltaic panel 54 is electrically connected to the battery 52.

[0034] As can be seen from the above, the H-shaped structure has high strength and stability, enabling the support frame 51 to effectively disperse and bear the pressure from the upper equipment or load. The controller 9 can also receive the solar position information collected by the solar tracker 55 and send control instructions to the drive motor 53 according to this information. The photovoltaic panel 54 can convert solar energy into electrical energy and transmit the generated electrical energy to the battery 52 for storage through electrical connection.

[0035] Application example: This design is applied to various highway bridges, such as large-scale cross-river / sea bridges, which are long-term subjected to vehicle loads, wind and wave impacts, and geological settlement effects, and need to monitor the vertical displacement of bridge piers and bridge decks in real time; mountain valley bridges are located in earthquake-prone areas with complex geological conditions and are prone to uneven settlement, and need long-term tracking and monitoring; urban elevated bridges have heavy traffic flow and complex underground pipelines, and need to monitor the change in bridge deck flatness caused by foundation settlement; bridges on soft soil foundations have low foundation bearing capacity and are prone to creep settlement, and need to monitor the settlement rate at high frequencies. This design monitors the settlement of bridge roads by setting up the measuring mechanism 2, using multi-sensor fusion, and cross-verifying multi-source data to improve the accuracy of settlement judgment. By setting up the installation mechanism 4, the entire measuring device can be firmly installed on the bridge guardrail 6, which is also convenient for installing or disassembling the measuring device. By setting up the photovoltaic mechanism 5, electrical energy can be provided for the use of the entire measuring device, reducing the use cost and saving energy.
