Description

Technical Field

[0001] This utility model relates to the field of visual monitoring of cable-stayed bridges, specifically a lightweight visual monitoring support structure for cable-stayed bridges. Background Technology

[0002] In the field of modern bridge engineering, cable-stayed bridges, with their unique structural form and excellent mechanical properties, have become an important type of bridge that spans obstacles such as rivers, lakes, seas, and canyons. As the key load-bearing component of cable-stayed bridges, the health of the stay cables is directly related to the structural safety and operational stability of the entire bridge. In order to ensure the safe operation of cable-stayed bridges, it is crucial to conduct real-time and effective health monitoring of the stay cables. Visual monitoring, as a non-contact monitoring method, has the advantages of being intuitive, comprehensive, and information-rich, and can obtain key information such as changes in the appearance of the stay cable surface, the location and extent of damage.

[0003] Existing visual monitoring technologies and related devices for cable stays still have many shortcomings. In terms of the movement of monitoring supports, traditional devices have a single and inflexible movement method. Some devices rely solely on simple sliding structures to move on the cable stays, lacking effective limiting and flexible adjustment mechanisms. When a change of position is required, not only is movement difficult, but it is also difficult to accurately control the movement distance and direction, making it impossible to quickly and accurately reach the designated monitoring position. At the same time, during the movement, there is a lack of real-time monitoring and adjustment of the horizontal state of the support, which can easily lead to the support tilting, affecting the accuracy and stability of monitoring, and may even damage the monitoring equipment due to excessive tilting. In addition, the monitoring angle adjustment of existing devices is inconvenient. The monitoring equipment is usually fixedly installed, making it difficult to flexibly adjust the angle according to the monitoring needs of different parts of the cable stays, resulting in some areas not being monitored and creating monitoring blind spots. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight cable-stayed bridge visual monitoring support structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lightweight cable-stayed bridge visual monitoring support structure includes,

[0007] The outer ring has multiple elastic telescopic sections on its surface, and an auxiliary mechanism is provided on the side surface of the outer ring. The auxiliary mechanism includes a moving component and a monitoring component, and the monitoring component is used to observe the surface condition of the cable.

[0008] The moving component includes: a connecting block, which is disposed on both sides of the outer ring, a level detector is disposed on the side surface of the connecting block, and a fixing rod is disposed on both sides of the connecting block.

[0009] Furthermore, a connecting rod is provided on one side of the fixed rod, an electric rotating shaft is provided at the connection between the connecting rod and the fixed rod, and an unmanned aerial vehicle wing is provided at one end of the connecting rod.

[0010] Furthermore, the moving component also includes: multiple rolling wheels, all of which are disposed on the inner side surface of the outer ring, and the inner side surface of the outer ring is also provided with multiple limiting arc plates, and a small electric telescopic tube is disposed between the limiting arc plates and the side surface of the outer ring.

[0011] Furthermore, the monitoring component includes: multiple monitoring housings, each of which is disposed on the outer surface of the outer ring, and two connecting feet are provided at the bottom of the monitoring housing, with an electric turntable provided at the connection between the connecting feet and the outer ring.

[0012] Furthermore, one end of the monitoring housing is provided with a plurality of small telescopic rods, and the output shaft end of the small telescopic rods is provided with a force-bearing strip.

[0013] Furthermore, a cleaning arc plate is provided on one side surface of the stress-bearing strip, and a monitoring camera is provided inside the monitoring housing, with the bottom surface of the monitoring camera connected to the outer surface of the outer ring.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. In this solution, by incorporating a movable component and a small electric telescopic tube in conjunction with a limiting arc plate, flexible control of the rolling wheel's position is achieved. When the support needs to be moved, the small electric telescopic tube precisely extends and retracts, quickly releasing the constraint of the limiting arc plate on the rolling wheel, allowing it to roll freely and improving the convenience and flexibility of movement. Simultaneously, a horizontal detector provides real-time feedback on the support's horizontal status data, which, combined with the control system, controls the rotation of the electric shaft, thereby adjusting the angle and position of the drone wing. This coordinated movement method of the drone wing and the rolling wheel enables flexible and stable movement on the cable-stayed bridge. It can also precisely adjust the movement posture according to the actual conditions such as the slope and direction of different cable-stayed bridges, ensuring that the support quickly and accurately reaches the designated monitoring position. After moving into position, the small electric telescopic tube once again plays a role, causing the limiting arc plate to quickly and firmly limit the rolling wheel, effectively preventing the rolling wheel from rolling arbitrarily and ensuring the positional stability of the support in complex environments, providing a reliable guarantee for subsequent monitoring work.

[0016] 2. In this solution, a monitoring component is installed. By activating an electric turntable to rotate the connecting legs, the angle of the monitoring housing can be precisely adjusted, ensuring that the monitoring camera is always aimed at the cable-stayed section to be monitored from the optimal angle. This improves the targeting and accuracy of the monitoring, ensuring the acquisition of comprehensive and clear cable-stayed image data. During monitoring, when dust or debris appears on the surface of the monitoring housing or the camera lens, affecting the monitoring effect, a small telescopic rod responds quickly, pushing the load-bearing strip to move the cleaning arc plate. This promptly cleans the surface of the monitoring equipment, ensuring the image quality of the monitoring camera and avoiding monitoring errors caused by surface contamination. The cleaning arc plate also moderately cleans the surface of the cable-stayed section, removing dust and debris to prevent additional stress caused by extra debris on the cable-stayed section surface. This ensures the structural safety of the cable-stayed section from the source and provides strong support for more accurate assessment of the cable-stayed section's health status.

[0022] 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.

[0023] Example 1: Please refer to Figures 1 to 4 A lightweight cable-stayed bridge visual monitoring support structure, comprising:

[0024] The outer ring 1 has multiple elastic telescopic sections 5 on its surface. The side surface of the outer ring 1 is provided with an auxiliary mechanism, which includes a moving component and a monitoring component. The moving component includes multiple rolling wheels 3, which are all located on the inner side surface of the outer ring 1. The inner side surface of the outer ring 1 is also provided with multiple limiting arc plates 4. A small electric telescopic tube is provided between the limiting arc plates 4 and the side surface of the outer ring 1. Both sides of the outer ring 1 are provided with connecting blocks 6. The side surface of the connecting blocks 6 is provided with a horizontal detector 10. Both sides of the connecting blocks 6 are provided with fixed rods 9. One side of the fixed rods 9 is provided with a connecting rod 8. An electric rotating shaft is provided at the connection between the connecting rod 8 and the fixed rod 9. One end of the connecting rod 8 is provided with a drone wing 7.

[0025] When the lightweight cable-stayed bridge visual monitoring support structure needs to be moved and adjusted during use, the small electric telescopic tube is activated to extend and retract, adjusting the distance between the limiting arc plate 4 and the side surface of the outer ring 1. This releases the limiting arc plate 4 from the limiting constraint on the rolling wheel 3, allowing the rolling wheel 3 to roll freely on the inner side surface of the outer ring 1. At the same time, the level detector 10 monitors the horizontal state of the support in real time and feeds the data back to the control system. According to actual needs, the control system controls the electric rotating shaft to rotate, driving the connecting rod 8 to rotate relative to the fixed rod 9, thereby adjusting the angle and position of the drone wing 7. Through the rotation of the drone wing 7 and the rolling of the rolling wheel 3, the support can move flexibly on the cable-stayed bridge. When it moves to the appropriate position, the small electric telescopic tube is activated again, causing the limiting arc plate 4 to move closer to the rolling wheel 3 and limit it, preventing the rolling wheel 3 from rolling randomly and ensuring the stability of the support position.

[0026] The monitoring components include: multiple monitoring housings 2, all of which are disposed on the outer surface of the outer ring 1. Two connecting legs 13 are provided at the bottom of the monitoring housing 2. An electric turntable is provided at the connection between the connecting legs 13 and the outer ring 1. Multiple small telescopic rods 15 are provided at one end of the monitoring housing 2. A force-bearing strip 14 is provided at the end of the output shaft of the small telescopic rod 15. A cleaning arc plate 11 is provided on one side surface of the force-bearing strip 14. A monitoring camera 12 is disposed inside the monitoring housing 2. The bottom surface of the monitoring camera 12 is in contact with the outer surface of the outer ring 1.

[0027] After reaching the designated detection position, the bracket position is fixed, and the electric turntable is started. The electric turntable drives the connecting support leg 13 to rotate, thereby adjusting the angle of the monitoring housing 2 so that the monitoring camera 12 is aligned with the cable section to be monitored. The monitoring camera 12 starts working, performing real-time visual monitoring of the cable and transmitting the monitored image data to the background processing system for analysis. During the monitoring process, if there is dust or debris on the surface of the monitoring housing 2 or the lens of the monitoring camera 12 that affects the monitoring effect, the small telescopic rod 15 is activated. The output shaft of the small telescopic rod 15 extends and pushes the force-bearing plate 14 to move. The force-bearing plate 14 drives the cleaning arc plate 11 to move. The cleaning arc plate 11 cleans the surface of the cable, removing dust and debris, thereby ensuring that the surface of the cable will not have additional debris that would increase additional stress.

[0028] Working principle:

[0029] When the device is moved, the staff activates the small electric telescopic tube to adjust the distance between the limiting arc plate 4 and the side surface of the outer ring 1, thereby releasing the restriction on the rolling wheel 3. The rolling wheel 3 can roll freely. At the same time, the horizontal detector 10 feeds back the horizontal status data of the support to the control system in real time. The control system controls the electric rotating shaft to rotate, driving the connecting rod 8 and the drone wing 7 to adjust their angles and positions. The two work together to allow the support to move flexibly on the cable. After reaching the appropriate position, the small electric telescopic tube is activated again to limit the rolling wheel 3 with the limiting arc plate 4, ensuring the stability of the support.

[0030] During monitoring, after the bracket is fixed in position, the electric turntable is started, which drives the connecting leg 13 to rotate and adjusts the angle of the monitoring housing 2 so that the monitoring camera 12 is aimed at the cable section for real-time monitoring. The image data is transmitted to the background for analysis. If there is dust or debris on the surface of the monitoring housing 2 or the lens, the small telescopic rod 15 is started to push the stress plate 14 and the cleaning arc plate 11 to move and clean the surface of the cable, preventing additional stress caused by debris and ensuring the monitoring effect and the safety of the cable.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
