[0027] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:

[0029] The specific structure of this utility model is as follows: Figures 1-3 As shown, its main structure includes a housing 10 fixed to the bridge, a crack monitoring component 20, an environmental acquisition sensor module 40, and a monitoring camera 30 mounted on the housing 10. By integrating the monitoring camera 30, the crack monitoring component 20, and the environmental acquisition sensor module 40 onto the housing 10, the housing 10 can be fixed in high-risk areas prone to cracking during use; thus transforming traditional comprehensive crack monitoring of the bridge into real-time focused monitoring of high-risk areas of the bridge prone to cracking.

[0030] Specifically, such as Figure 1As shown, the crack monitoring assembly 20 can move horizontally reciprocatingly to monitor the crack condition of the monitoring area of the bridge bottom region directly above the movement path of the crack monitoring assembly 20. The environmental collection sensor module 40 and the monitoring camera 30 are installed at both ends of the movement path of the crack monitoring assembly 20, and the monitoring area of the crack monitoring assembly 20 at the bridge bottom is located in the collection area of the monitoring camera 30. In implementation, the bridge bottom image information of the monitoring area of the crack monitoring assembly 20 is collected by the monitoring camera 30 to the control platform to understand the crack condition of the monitoring area; in combination with the monitoring result of the monitoring camera 30, when the crack is monitored, the crack monitoring assembly 20 can be controlled to move to the crack to monitor and analyze the crack condition. At the same time, the environmental collection sensor module 40 also collects the recent environmental information in real time and transmits to the control platform for analyzing the crack generating factors. In summary, the monitoring camera 30, the crack monitoring assembly 20 and the environmental collection sensor module 40 integrated on the shell 10 provide a physical hardware platform for the crack monitoring of the bridge and the data collection of the crack generating reasons.

[0031] Of course, the integration of the monitoring camera 30, the crack monitoring assembly 20 and the environmental collection sensor module 40 in the present application can only replace the detection module in actual implementation, so that the material hardware platform built in the present application can not only realize the monitoring of the bridge crack, but also can be used for other monitoring operations of the bridge. For example, the crack monitoring assembly 20 is replaced by a distance sensor to monitor the settlement of the bridge bottom.

[0032] By integrating the monitoring camera 30 and the crack monitoring assembly 20 on the shell 10, the real-time monitoring of the crack generation in the collection area and the real-time monitoring and analysis of the crack data condition can be realized. In addition, by integrating the environmental collection sensor module 40 on both sides of the movement path of the crack monitoring assembly 20, the environmental data of the monitoring area can be collected in real time, so that the crack generating factors can be analyzed by the environmental data to provide data support for the later maintenance and maintenance of the bridge.

[0033] Preferably, the environmental collection sensor module 40 includes a temperature and humidity sensor and a vibration sensor for collecting real-time environmental data such as temperature, humidity and bridge vibration. Specifically, the environmental collection sensor module 40 can also increase or decrease the number and / or type of sensors according to the actual environmental data needs.

[0034] On the basis of the above, Figure 3 As shown, the crack monitoring assembly 20 includes a power seat 21 and a crack sensor 24 installed on the power seat 21. As shown in Figure 2As shown, the inside of the shell 10 has a moving channel for the movement of the crack monitoring assembly 20, the inside of the moving channel is arranged with a driving groove 17 arranged along the moving direction of the crack monitoring assembly 20, and the driving groove 17 is fixed with a rack 171 arranged along the groove length direction. Further as shown Figure 3 As shown, the power seat 21 is rotatably fitted with a gear 22 driven by a motor, and the gear 22 and the rack 171 form meshing transmission. In implementation, the gear 22 is driven to rotate by the motor, and the meshing transmission between the gear 22 and the rack 171 can drive the power seat 21 to produce horizontal reciprocating movement in the moving channel, thereby quickly driving the crack monitoring assembly 20 to the corresponding crack for crack condition analysis. The driving mode using the meshing of the gear 22 and the rack 171 has the advantages of large driving stroke and small space occupation compared with the straight stroke transmission structure of the cylinder.

[0035] Further, as shown Figure 1 and Figure 2 As shown, the inside of the moving channel is also arranged with a rolling groove 16 arranged along the moving direction of the crack monitoring assembly 20, and the rolling groove 16 and the driving groove 17 are arranged on both sides of the moving channel. As shown Figure 3 As shown, the power seat 21 is also rotatably fitted with a roller 23 which forms rolling cooperation with the moving channel, and the rotation axes of the roller 23 and the gear 22 are both horizontally arranged and perpendicular to the length direction of the moving channel. The structure arrangement uses the rolling of the roller 23 in the rolling groove 16 and the meshing rolling of the gear 22 on the rack 171 to integrally support the power seat 21 as a whole, effectively reducing the resistance in the movement of the power seat 21 and improving the stability of the movement of the power seat 21.

[0036] In addition, as shown Figure 3 As shown, the top of the power seat 21 has a sunken groove 211, and the crack sensor 24 is arranged at the groove bottom of the sunken groove 211. The embedded installation of the crack sensor 24 uses the cavity of the sunken groove 211 to protect the crack sensor 24 from collision, thereby prolonging the service life of the crack sensor 24. In addition, there is a water leakage gap between the outer periphery of the crack sensor 24 and the groove wall of the sunken groove 211, and a water leakage hole 212 penetrating the groove bottom of the sunken groove 211 is arranged directly below the water leakage gap for draining rainwater to prevent the crack sensor 24 from being damaged by water seepage.

[0037] On the basis of the above, the two ends of the shell 10 are arranged with inner grooves 15, and the environmental collection sensor module 40 is arranged in the inner grooves 15. Similarly, the design structure of the embedded environmental collection sensor module 40 also achieves protection of the environmental collection sensor module 40. At the same time, the upper groove wall of the inner groove 15 can be used as a handle for lifting the shell 10 by virtue of the arrangement of the inner grooves 15 at both ends of the shell 10.

[0038] For the convenience of night monitoring operation, as shown in Figure 1 The upper part of the shell 10 is provided with an infrared illuminator 50 pointing to the collection area, which assists the night monitoring work of the monitoring camera 30 and improves the accuracy of monitoring.

[0039] In addition, in order to realize the rapid installation of the bridge of the present application, as shown in Figure 1 The upper part of the shell 10 is provided with an infrared illuminator 50 pointing to the collection area, which assists the night monitoring work of the monitoring camera 30 and improves the accuracy of monitoring. The upper part of the shell 10 is provided with an infrared illuminator 50 pointing to the collection area, which assists the night monitoring work of the monitoring camera 30 and improves the accuracy of monitoring.

[0040] Further, as shown in Figure 1 The upper part of the shell 10 is provided with an infrared illuminator 50 pointing to the collection area, which assists the night monitoring work of the monitoring camera 30 and improves the accuracy of monitoring.

[0041] In addition, as shown in Figure 1 The upper part of the shell 10 is provided with an infrared illuminator 50 pointing to the collection area, which assists the night monitoring work of the monitoring camera 30 and improves the accuracy of monitoring.

[0042] It should be noted that the utility model protects not software, but the physical platform formed by the circuit and hardware, and the present application does not extend to the protection of related software. Specifically, in the present application, the monitoring camera 30, the crack sensor 24 in the crack monitoring assembly 20, the temperature and humidity sensor and the vibration sensor in the environment collection sensor module 40 are all prior art, and their working principles will not be repeated here.
