Description

Technical Field

[0001] This application relates to the field of bridge inspection technology, and in particular to a bridge defect detection device. Background Technology

[0002] With the continuous development of transportation, bridges serve as vital transportation hubs connecting rivers, lakes, seas, valleys, and ravines. However, during their use, bridges inevitably develop various defects due to factors such as material aging, environmental erosion, and load-bearing effects. Therefore, regular inspections of bridge defects are necessary.

[0003] A search revealed Chinese patent CN222259179U, which discloses a high-definition detection device for bridge defects in narrow spaces. This device features a long, lightweight telescopic rod for easy one-handed operation (increasing the extension length and reducing the weight of the rod for easier operation); it allows for omnidirectional observation of the supports (the telescopic function of the fixing device enables defect detection and recording in the space behind the supports and other blind spots); and it allows for wireless image transmission (images can be wirelessly transmitted to the detection system via smart devices). However, this device lacks protection for the lens of the high-definition detection equipment. During the detection process, the narrow spaces such as bridge supports contain a large amount of dust and moisture, which can easily contaminate the lens and lead to inaccurate detection results. Therefore, this paper proposes a bridge defect detection device to address these issues. Utility Model Content

[0015] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0016] The technical solutions provided by the various embodiments of this application are described in detail below with reference to the accompanying drawings.

[0017] Please see Figure 1-4 This utility model provides a technical solution for a bridge defect detection device: A bridge defect detection device includes: a detection camera 1; a support frame 2 for supporting the detection camera 1; and a protective plate switching assembly 3 disposed at the front end of the support frame 2, which includes: a housing 31 fixedly connected to the front end of the support frame 2; a plurality of protective plates 32 disposed inside the housing 31 and arranged in a circumferential array; and a driving member 33 disposed inside the housing 31 for driving the plurality of protective plates 32 to switch positions, such that one of the protective plates 32 is directly facing the detection camera 1.

[0018] Specifically, by setting the protective sheet 32 ​​to be located directly in front of the detection camera 1, the lens of the detection camera 1 is protected. By setting the driving component 33, when the protective sheet 32 ​​in use is contaminated, a clean protective sheet 32 ​​can be quickly replaced without interrupting the detection work for manual cleaning. This significantly improves the efficiency of operation in dirty environments, ensures the continuity and efficiency of detection, and ensures the accuracy of detection results.

[0019] The driving component 33 includes a rotating disk 331. The front of the rotating disk 331 has an embedded hole arranged in a circumferential array. The protective sheet 32 ​​is detachably connected to the inner wall of the embedded hole. By rotating the rotating disk 331, the protective sheet 32 ​​is switched to replace it with a clean one.

[0020] The front of the housing 31 has an opening 311 that faces the detection camera 1 to ensure the field of view of the detection camera 1.

[0021] A switching motor 332 is fixedly connected to the inner wall of the support frame 2. The output end of the switching motor 332 is fixedly connected to the rotating disk 331, and the rotating disk 331 is driven to rotate through the output end of the switching motor 332.

[0022] It also includes a support rod 4, which is preferably composed of multiple short rods connected end-to-end by threads. In this embodiment, an angle adjustment mechanism 5 is fixedly connected to the top of the support rod 4. This angle adjustment mechanism 5 has been disclosed in the relevant patent CN222259179U, specifically as follows: "The angle adjustment mechanism 5 includes a ball joint, an elastic ball groove, and a locking cover. A support rod is fixedly installed above the ball joint, and the upper end of the support rod is connected to the sleeve through a connecting plate. The lower part of the inner wall of the locking cover has internal threads, and the upper part of the inside of the locking cover is conical. A through hole is opened at the top of the locking cover, through which the support rod passes and can move along the through hole. The ball joint is located inside the locking cover, and the elastic ball groove is conical and connects with the inside of the locking cover." The upper part of the ball joint can be inserted into the elastic ball groove. The lower end of the elastic ball groove is fixedly installed with a connecting rod with external threads. The connecting rod is connected to the lower thread of the inner wall of the locking cover. When the angle needs to be adjusted, the support rod is rotated, and the support rod drives the ball joint to rotate in the elastic ball groove, thereby realizing 360° rotation of the detection equipment and achieving full coverage of the display screen. The movable end of the angle adjustment mechanism 5 is fixedly connected to the longitudinal adjustment component 6. The support frame 2 is set inside the longitudinal adjustment component 6 and can move along the axial direction of the longitudinal adjustment component 6. The longitudinal adjustment component 6 adjusts the extension length of the support frame 2 to ensure the clarity of the image captured by the detection camera 1.

[0023] The longitudinal adjustment assembly 6 includes a cylinder 61. A mobile power supply is installed on the top of the cylinder 61, and the detection camera 1 is connected to a display via a signal for user observation. An end cap 62 is fixedly connected to the end of the cylinder 61, and an opening 63 is formed between the end cap 62 and the cylinder 61 for the support frame 2 to move. A threaded screw 64 is rotatably connected to the inner wall of the cylinder 61, and the threaded screw 64 is threadedly connected to the support frame 2. A drive motor 65 is fixedly connected to the end of the cylinder 61, and the output end of the drive motor 65 is fixedly connected to one end of the threaded screw 64. The output end of the drive motor 65 drives the threaded screw 64 to rotate, and the threaded screw 64 drives the support frame 2 to move along the axial direction of the cylinder 61. The support frame 2 drives the detection camera 1 to move.

[0024] The support frame 2 includes a horizontal plate 21 and a first vertical plate 22 and a second vertical plate 23, which are fixedly connected to both ends of the horizontal plate 21. The detection camera 1 is fixedly connected to the back of the first vertical plate 22 through the mounting bracket 7. The second vertical plate 23 is threadedly connected to the surface of the threaded screw 64. The horizontal plate 21 passes through the passage 63, separating the driving part, i.e., the second vertical plate 23, and the bearing part, i.e., the first vertical plate 22, to ensure the rigidity and stability of the equipment during the telescopic movement, prevent the detection camera 1 from shaking, and ensure clear images.

[0025] Working principle: When using this bridge defect detection device, the user first holds or holds the support rod 4 and moves the device to the bridge area to be inspected. Using the angle adjustment mechanism 5, the user adjusts the horizontal and vertical angles of the detection camera 1 so that it is roughly facing the area to be inspected. Then, the user starts the drive motor 65, which drives the threaded screw 64 to rotate, thereby moving the support frame 2 and the detection camera 1 axially along the cylinder 61, achieving precise extension and retraction of the detection camera 1. During this process, by observing the real-time image on the monitor connected to the detection camera 1, the user adjusts the detection camera 1 to the optimal observation distance and focuses on the target. The system focuses on the disease and completes preliminary observation and image recording. When the protective sheet 32 ​​in the protective sheet switching assembly 3 is found to be contaminated by dust, water stains or oil during the detection process, resulting in a decrease in image quality, the switching motor 332 is activated to drive the rotating disk 331 to rotate, switching the next clean protective sheet 32 ​​to the position directly facing the lens of the detection camera 1. The contaminated protective sheet 32 ​​is then removed from the working area. After obtaining a clear field of view, the above steps are repeated to continue disease detection and data recording, thereby ensuring the continuity and efficiency of detection and ensuring the accuracy of the detection results.
