Description

Technical Field

[0001] This utility model relates to the field of cable calibration, specifically to an adaptive calibration structure for cable vibration displacement. Background Technology

[0002] As a key load-bearing component in modern bridge engineering, stay cables play a crucial role in the structural system of bridges. With their high strength and lightweight characteristics, they tightly connect bridge towers and bridge decks, effectively sharing the load borne by the bridge and ensuring its stability and safety. However, under the long-term effects of complex and ever-changing natural environments and dynamic loads such as vehicles and wind, stay cables inevitably vibrate. The accurate measurement and calibration of their vibration displacement has become an important issue in the field of bridge health monitoring.

[0003] The existing technology still has many shortcomings. In terms of protection, the existing technology lacks an effective dynamic protection mechanism. When encountering severe weather such as rain and sandstorms, the laser displacement sensor is directly exposed to the outside. Rainwater and sand will directly contact the sensor, causing pollution and damage to its optical components, which seriously affects the measurement accuracy and stability, and may even lead to sensor failure and inability to work properly. In terms of cleaning, the existing technology also has obvious defects. Dust and other impurities easily accumulate on the sensor surface, interfering with the propagation and reflection of the laser, thus affecting the accuracy of the measurement results. However, the existing technology lacks an automatic and effective cleaning device, which usually requires manual cleaning at regular intervals. This not only consumes a lot of manpower and time, but also may cause secondary damage to the sensor due to improper operation during the cleaning process. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive calibration structure for the vibration displacement of a cable-stayed bridge, so as to solve the problems mentioned in the background art.

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

[0006] An adaptive calibration structure for cable vibration displacement includes,

[0007] A fixed base plate is provided with a mounting base on its upper surface. A laser displacement sensor is provided on the upper surface of the mounting base. A protective component is also provided on the upper surface of the fixed base plate. The protective component includes a baffle component and a cleaning component.

[0008] The baffle component includes: a top cover plate, which is disposed on the upper surface of the laser displacement sensor, and rotating side plates are respectively disposed on both sides of the top cover plate, and an electric rotating shaft is disposed at the connection between the two rotating side plates and the top cover plate;

[0009] The cleaning component includes: a water storage box, which is disposed on the upper surface of a fixed base plate. A top plate is disposed on the upper surface of the water storage box. A water storage pipe is disposed on one side surface of the top plate. A lifting frame is disposed inside the water storage pipe. An internal filter screen is disposed inside the lifting frame.

[0010] Furthermore, a bottom spring is provided between the lifting frame and the inner bottom surface of the water storage pipe, and water outlets are provided on both sides of the water storage pipe. An auxiliary water outlet is provided on the side surface of the lifting frame to cooperate with the water outlet.

[0011] Furthermore, the two sides of the water storage pipe are respectively provided with drainage ramps that cooperate with the water outlet. The bottom surface of the drainage ramp is in contact with the upper surface of the top plate. The upper surface of the water storage box is provided with a water inlet, and the upper surface of the top plate is provided with two drainage outlets that are connected to the water inlet.

[0012] Furthermore, two drive motors are provided on the upper surface of the drain outlet, and a cleaning scraper is provided at the end of the output shaft of the drive motor. A connecting side strip is provided on one side of the cleaning scraper, and a water-blocking block is provided on one side surface of the connecting side strip. A sealing layer is provided on the bottom surface of the water-blocking block. Two cleaning ports are also opened on the upper surface of the top plate, and the cleaning ports are located below the water-blocking block.

[0013] Furthermore, a water spray end is provided on one side surface of the water storage box, and a water spray nozzle is provided on one side surface of the water spray end. Two telescopic motors are provided on the upper surface of the fixed base plate, and cleaning rollers are provided at the output shaft ends of the two telescopic motors.

[0014] Furthermore, a viewing window is provided on one side surface of the rotating side plate, a movable baffle is provided on the side surface of the top cover plate, and a shaft is provided at the connection between the movable baffle and the top cover plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this solution, by setting up a baffle component, the rotating side plate driven by the electric shaft is combined with the movable baffle. During normal operation, the rotating side plate and the top cover plate form a basic protective space, providing initial protection for the laser displacement sensor. When encountering severe weather, the staff can remotely control the electric shaft to rotate and retract the rotating side plate, forming a relatively closed space with the top cover plate, effectively blocking rain and dust. In particular, the movable baffle is pushed and rotated during the retraction of the rotating side plate, forming a rain shield above the rotating side plate, further enhancing the protective effect and improving the adaptability and stability of the laser displacement sensor in complex environments.

[0017] 2. In this solution, a cleaning component is installed. During rainy weather, rainwater is collected by a lifting frame inside the water storage pipe. The rainwater undergoes double filtration using an internal filter, allowing clean water to enter the water storage box for storage. This achieves natural collection and purification of water resources. When the laser displacement sensor needs cleaning, water in the water storage box is sprayed out through the nozzle to wet the cleaning roller. The telescopic motor drives the cleaning roller to rise, removing dust from the sensor surface through friction. At the same time, the drive motor drives the cleaning scraper to scrape the surface of the drain outlet. The connecting side strip moves the water baffle to expose the cleaning opening, discharging debris. This solution overcomes the limitations of traditional cleaning methods, eliminating the need for large amounts of additional water resources and complex manual operations, thus improving cleaning efficiency.

[0023] 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.

[0024] Example 1: Please refer to Figs. 1 to 4 An adaptive calibration structure for the vibration displacement of a cable-stayed bridge includes:

[0025] A fixed base plate 1 is provided, and a mounting base 3 is provided on the upper surface of the fixed base plate 1. A laser displacement sensor 7 is provided on the upper surface of the mounting base 3. A protective component is also provided on the upper surface of the fixed base plate 1. The protective component includes a baffle component and a cleaning component. The baffle component includes: a top cover plate 11, which is provided on the upper surface of the laser displacement sensor 7. Rotating side plates 9 are provided on both sides of the top cover plate 11. An electric rotating shaft is provided at the connection between the two rotating side plates 9 and the top cover plate 11. A viewing window 10 is provided on one side of the rotating side plate 9. A movable baffle 13 is provided on the side of the top cover plate 11. A shaft is provided at the connection between the movable baffle 13 and the top cover plate 11.

[0026] When in use, the electric rotating shaft is in its initial state when the cable-stayed bridge vibration displacement adaptive calibration structure is working normally, keeping the rotating side plate 9 at a certain angle to the top cover plate 11, providing basic protective space for the laser displacement sensor 7. In case of severe weather, such as rain or sandstorms, the operator can remotely control the electric rotating shaft to start, causing the rotating side plate 9 to rotate around it, so that the two rotating side plates 9 move closer to the middle until they form a relatively closed space with the top cover plate 11, effectively blocking rainwater and sand from directly contacting the laser displacement sensor 7 and protecting its normal operation. The viewing window 10 allows the operator to observe the working status of the laser displacement sensor 7 without opening the protective structure. The movable baffle 13 is connected to the top cover plate 11 through the shaft. When the two rotating side plates 9 rotate and retract, it will touch and cause them to rotate, and finally form a rain shield above the two rotating side plates 9.

[0027] The cleaning components include: a water storage box 2, which is located on the upper surface of a fixed base plate 1. A top plate 8 is located on the upper surface of the water storage box 2. A water storage pipe 12 is located on one side of the top cover plate 11. A lifting frame 16 is located inside the water storage pipe 12. An internal filter screen 20 is located inside the lifting frame 16. A bottom spring 21 is located between the lifting frame 16 and the bottom surface of the water storage pipe 12. Water outlets 18 are located on both sides of the water storage pipe 12. An auxiliary water outlet corresponding to the water outlet 18 is located on the side surface of the lifting frame 16. Drainage ramps 14 corresponding to the water outlets 18 are located on both sides of the water storage pipe 12. The bottom surface of the drainage ramps 14 is attached to the upper surface of the top plate 8. The upper surface of the water storage box 2... The top plate 8 has a water inlet and two drain outlets 17 connected to the water inlet. Two drive motors 25 are installed on the upper surface of the drain outlets 17. A cleaning scraper 24 is installed at the end of the output shaft of the drive motor 25. A connecting side strip 23 is installed on one side of the cleaning scraper 24. A water blocking block 19 is installed on one side of the connecting side strip 23. A sealing layer 22 is installed on the bottom surface of the water blocking block 19. Two cleaning ports are also installed on the upper surface of the top plate 8. The cleaning ports are located below the water blocking block 19. A water spray end 4 is installed on one side of the water storage box 2. A water spray nozzle 15 is installed on one side of the water spray end 4. Two telescopic motors 6 are installed on the upper surface of the fixed base plate 1. A cleaning roller 5 is installed at the end of the output shaft of the two telescopic motors 6.

[0028] When the equipment encounters rainy weather, the lifting frame 16 inside the water storage pipe 12 can collect rainwater and filter impurities in the rainwater through the internal filter screen 20, so that the cleaner water is located below the internal filter screen 20. When too much rainwater accumulates inside the lifting frame 16, the lifting frame 16 will press the bottom spring 21 and descend, eventually aligning the auxiliary water outlet on the side surface of the lifting frame 16 with the water outlet 18. The water inside the lifting frame 16 will exit from the water outlet 18 and slide down through the drain ramp 14. When the rainwater reaches above the drain outlet 17, it will be filtered again and then enter the water storage box 2 for storage through the drain outlet 17. When it is necessary to clean the detection part of the laser displacement sensor 7, firstly Water in the water storage box 2 is sprayed out through the spray nozzle 15 of the spray end 4 and sprayed onto the surface of the cleaning roller 5. Then, the two telescopic motors 6 are automatically started, driving the cleaning roller 5 to lift. The dust on the surface of the cleaning roller 5 is removed by friction between the cleaning roller 5 and the side of the laser displacement sensor 7. After a period of use, the two drive motors 25 will automatically start and extend. During the extension process, the cleaning scraper 24 scrapes the surface of the drain outlet 17 to remove the debris. During the movement of the cleaning scraper 24, the water blocking block 19 will also move due to the connection effect of the connecting side strip 23, exposing the cleaning port below. The debris is pushed to the cleaning port by the cleaning scraper 24 and discharged through the cleaning port.

[0029] Working principle:

[0030] During normal operation, the electric shaft 1 keeps the rotating side plate 2 at a certain angle to the top cover plate 3, providing basic protection for the laser displacement sensor 4. In case of severe weather, the staff can remotely operate the electric shaft 1 to drive the rotating side plate 2 to move towards the middle, forming a closed space with the top cover plate 3 to block rain and dust. The viewing window 5 makes it easy to observe the status of the sensor 4. The movable baffle 6 rotates to form a rain shield when the rotating side plate 2 is closed.

[0031] In the cleaning component, during rainfall, the lifting frame 8 inside the water storage pipe 7 collects rainwater, and the internal filter screen 9 filters impurities. When too much rainwater accumulates, the lifting frame 8 descends, and the auxiliary water inlet 10 aligns with the outlet 11. The water passes through the drain ramp 12 and is filtered again before entering the water storage box 13 for storage. When cleaning the sensor 4, the water in the water storage box 13 is sprayed from the spray nozzle 14 onto the cleaning roller 15. The telescopic motor 16 drives the cleaning roller 15 to rise, rubbing away the dust on the surface of the sensor 4. After a period of use, the drive motor 17 drives the cleaning scraper 18 to extend and scrape away debris from the drain outlet 19. At the same time, the water baffle 20 moves to expose the cleaning port 21, and the debris is pushed into the cleaning port 21 and discharged.

[0032] 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.
