[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] As described in the background section, traditional monitoring methods mainly rely on manual inspections, which are not only time-consuming and labor-intensive, but also difficult to fully and accurately capture subtle changes in the bridge structure.

[0031] To solve this technical problem, this utility model provides a bridge monitoring device that is applied to bridge monitoring.

[0032] For details, please refer to Figures 1-3 The bridge monitoring equipment specifically includes:

[0033] Monitoring components installed above the bridge deck are used to capture real-time image information of the bridge surface;

[0034] Radar components installed under the bridge deck are used for monitoring the bridge deck, the area under the bridge, and both sides of the bridge.

[0035] The monitoring component includes a bracket 1. One end of the bracket 1 is fixedly connected to the bridge via a fixed mounting bracket 2. The other end of the bracket 1 is provided with an adjustment component 3. A high-definition camera 4 is installed above the adjustment component 3. The high-definition camera 4 and the adjustment component 3 are rotatably connected via an adjustment component 2 5.

[0036] The bridge monitoring equipment provided by this utility model combines two monitoring methods: a monitoring component and a radar component. The monitoring component can capture real-time image information of the bridge surface to observe visible damage such as cracks and spalling. The radar component can penetrate the bridge surface to detect structural changes inside the bridge, such as steel corrosion and internal voids in the concrete. This comprehensive monitoring method greatly improves the comprehensiveness and accuracy of bridge monitoring.

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] Example 1:

[0039] Please refer to Figures 1-4 A bridge monitoring device, comprising:

[0040] Monitoring components installed above the bridge deck are used to capture real-time image information of the bridge surface;

[0041] A radar assembly installed beneath the bridge deck is used for monitoring the bridge deck, the area beneath the bridge, and both sides of the bridge; the radar assembly includes a radar and a corner reflector.

[0042] Specifically, the monitoring component includes a bracket 1. One end of the bracket 1 is fixedly connected to the bridge via a mounting bracket 2. The other end of the bracket 1 is equipped with an adjustment component 3. A high-definition camera 4 is mounted above the adjustment component 3. The high-definition camera 4 and the adjustment component 3 are rotatably connected via an adjustment component 2. The mounting bracket 2 secures the bracket 1 and supports the high-definition camera 4. The adjustment components 3 and 2 allow for multi-angle adjustment of the bracket 1 to meet various usage requirements.

[0043] Furthermore, the fixed mounting bracket 2 has a connecting slot 7 on the side near the bracket 1. A right-angle plate 6 is fixedly connected to the end of the bracket 1 near the fixed mounting bracket 2. The right-angle plate 6 is vertically inserted into the connecting slot 7. The right-angle plate 6 and the connecting slot 7 are detachably fixedly connected by a fixing screw 8. It can be seen that by inserting the right-angle plate 6 at the end of the bracket 1 into the connecting slot 7 of the fixed mounting bracket 2, the bracket 1 can be quickly assembled and disassembled. The fixing screw 8 can limit the connection between the right-angle plate 6 and the fixed mounting bracket 2.

[0044] Specifically, adjustment component 1 3 includes a fixed base 9 and a rotating base 10. The fixed base 9 is fixedly connected to the bracket 1, and the rotating base 10 is located above the fixed base 9. The rotating base 10 is rotatably connected to the fixed base 9. The lower end of adjustment component 2 5 is connected to the top of the fixed base 9. Through the rotatable connection between the fixed base 9 and the rotating base 10, the horizontal angle adjustment of the high-definition camera 4 can be realized. Through adjustment component 2 5, the angle of the high-definition camera 4 can be adjusted a second time.

[0045] Furthermore, a wave-shaped guide frame 12 is fitted on the outer side of the fixed base 9, and a movable collar 11 is fitted on the outer side of the rotating base 10. The wave-shaped guide frame 12 is fixedly connected to the fixed base 9, and the movable collar 11 is vertically slidably connected to the rotating base 10. The lower end of the movable collar 11 is fastened to the upper end of the wave-shaped guide frame 12. A guide groove 13 is vertically opened on the outer side of the rotating base 10. A fixed slider 14 is fixedly connected to the inner side of the movable collar 11. The fixed slider 14 is located inside the guide groove 13 and is vertically slidably connected to the guide groove 13. A fixed top block 15 is fixedly connected to the top of the inner side of the guide groove 13. A thrust spring 16 is provided inside the guide groove 13 and at a position between the fixed slider 14 and the fixed top block 15.

[0046] It can be seen that when the rotating seat 10 rotates to adjust the orientation angle of the high-definition camera 4, the lower end of the movable collar 11 and the upper end of the wave-shaped guide frame 12 are separated and engaged. When the rotating seat 10 rotates, the lower end of the movable collar 11 is guided by the wave-shaped guide frame 12 to move the movable collar 11 upward. The fixed top block 15 is pressed by the fixed slider 14, which compresses the thrust spring 16. At the same time, the thrust spring 16 applies a continuous opposite force to the fixed slider 14, so that the fixed slider 14 can drive the movable collar 11 to move downward. Thus, the rotation positioning effect of the high-definition camera 4 can be achieved by the engagement of the movable collar 11 and the wave-shaped guide frame 12.

[0047] This application achieves the following effects through monitoring components and radar components:

[0048] Strong comprehensive monitoring capabilities: This invention combines two monitoring methods: a monitoring component and a radar component. The monitoring component can capture real-time image information of the bridge surface to observe visible damage such as cracks and spalling. The radar component can penetrate the bridge surface to detect structural changes inside the bridge, such as steel reinforcement corrosion and internal concrete voids. This comprehensive monitoring method greatly improves the comprehensiveness and accuracy of bridge monitoring.

[0049] Wide and flexible monitoring range: The radar assembly, using a combination of radar and corner reflectors, extends the monitoring range beyond the bridge surface to cover areas beneath and on both sides of the bridge, effectively avoiding blind spots. Furthermore, the radar's scanning angle and range can be adjusted as needed, enhancing monitoring flexibility.

[0050] High degree of automation: This invention employs automated monitoring technology, eliminating the need for manual inspections and significantly saving manpower and time costs. Simultaneously, monitoring data can be transmitted to the back-end management system in real time, facilitating data analysis and processing.

[0051] High adaptability: This invention is applicable to various types of bridges, whether urban viaducts, cross-river bridges, or mountain bridges, and can be customized for installation according to specific circumstances. Furthermore, the selection of radar and monitoring components can be adjusted based on the characteristics of the bridge and monitoring requirements.

[0052] Low maintenance costs: Although the initial installation cost may be high, the maintenance cost is relatively low considering the degree of automation and long-term monitoring benefits of this invention. The monitoring components and radar components, among other equipment, have high reliability and stability, enabling long-term stable operation and reducing maintenance frequency and costs.

[0053] Example 2:

[0054] The bridge monitoring equipment provided in Example 1 has been further optimized, specifically, as follows: Figure 5 As shown, specifically, the high-definition camera 4 includes a rotating base 17 and a connector 18. The rotating base 17 is fixed to the top of the rotating base 10, and the connector 18 is fixed to the lower end of the high-definition camera 4. The lower end of the connector 18 extends into the inner side of the rotating base 17, and the connector 18 is rotatably connected to the rotating base 17. Furthermore, a fastening knob 19 is provided at the connection between the rotating base 17 and the connector 18. When the fastening knob 19 is tightened, the friction between the rotating base 17 and the connector 18 increases.

[0055] Through the above structural design, the tilt angle of the high-definition camera 4 can be adjusted by rotating the rotating base 17 and the connecting piece 18, thereby improving the adaptability of the device. Furthermore, the friction between the rotating base 17 and the connecting piece 18 can be controlled by the fastening knob 19, making the adjustment of the high-definition camera 4 more convenient.

The lower end of the photovoltaic panel 20 is movably connected to the bracket 1 through the support frame 21. The photovoltaic panel 20 is electrically connected to the high-definition camera 4 and is used to power the high-definition camera 4.
