Abstract
Description
Technical Field
[0001] This utility model relates to a drone for bridge quality inspection, belonging to the technical field of drones for bridge quality inspection. Background Technology
[0002] Inspecting bridge structures for defects such as cracks is a major aspect of routine bridge maintenance. It provides crucial information and decision-making support for bridge condition identification, defect treatment, and safety assessment, making it a critical link in bridge maintenance. Currently, manual inspection and bridge inspection vehicles are the main methods for bridge inspection. However, manual inspection methods suffer from high risks, subjectivity, and time-consuming processes. While bridge inspection vehicles can compensate for areas inaccessible to personnel to some extent, they also have drawbacks such as impacting traffic safety, limited applicability to certain bridge types, and high costs. To address the problems of high risks, traffic disruption, and low efficiency associated with traditional manual inspection methods, this invention proposes an unmanned aerial vehicle (UAV) for bridge quality inspection.

Detailed Implementation
[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0014] Please see Figure 1-5This utility model discloses a schematic diagram of a UAV for bridge quality inspection. Its structure includes a UAV body 1, with two quick-release slides 2 aligned at the top and bottom left sides. A detection end 3 is movably mounted between the two quick-release slides 2 from left to right. Obstacle avoidance sensors 4 are installed on each side of the UAV body 1. The detection end 3 and each obstacle avoidance sensor 4 are electrically connected to the UAV body 1. A base frame 5 is installed on the bottom surface of the UAV body 1. The detection end 3 includes two locking supports 31, with a semi-circular slide rail 32 vertically arranged between the two locking supports 31. A direction-changing camera component 33 is movably mounted on the semi-circular slide rail 32. A control unit 34 for electrical connection with the direction-changing camera component 33 is installed on the right side of the upper locking support 31. The sliding angle of the direction-changing camera component 33 on the semi-circular slide rail 32 is 90º both vertically.
[0015] The two quick-release slides 2 include a slide body 21, and a slide groove 22 is provided on the top surface of the slide body 21, and a locking hole 23 is provided on the bottom right side of the slide groove 22.
[0016] The two card slot supports 31 include a support 311, and a card slot 312 is provided at the right end of the support 311. A telescopic card 313 for engaging with the card slot hole 23 for positioning is movably fitted in the card slot 312.
[0017] The directional camera assembly 33 includes a sliding seat 331 that is movably mounted on a semi-circular slide rail 32 and slides in an arc. A stabilization gimbal 332 is provided on the left side of the sliding seat 331, and a high-resolution camera 333 is provided on the left side of the stabilization gimbal 332. Multiple spotlights 334 are provided on the front and rear sides of the stabilization gimbal 332.
[0018] The control unit 34 has a built-in controller 341, and the controller 341 is electrically connected to an RTK module 342, a ranging module 343, and a storage module 344.
[0019] Working principle: Before testing, the detection end 3 is first mounted on the two quick-release slides 2 from left to right, and fixed by the engagement of the locking hole 23 with the telescopic locking piece 313. The detection end 3 is then electrically connected to the main body of the UAV 1, so that the detection end 3 can be operated on the control panel of the main body of the UAV 1. When the main body of the UAV 1 is flying and testing the key parts of the bridge such as the web, bottom plate, and wing flange, the obstacle avoidance sensors 4 will sense in real time and play a role in preventing collisions during the flight of the main body of the UAV 1.
[0020] During the flight inspection of the main body 1 of the UAV, the directional camera component 33 adjusts the corresponding angle of the high-resolution camera 333 on the control panel according to the bridge section to be inspected, so as to facilitate the inspection of the bridge from all directions. During the inspection, the anti-shake gimbal 332 assists the high-resolution camera 333 in preventing flight shaking, while the spotlight 334 provides auxiliary lighting for the high-resolution camera 333. When the high-resolution camera 333 detects a structural crack, it will take a picture. The RTK module 342 is used to record the location of the bridge image, the ranging module 343 is used to analyze the size of the crack, and the storage module 344 is used to store the image in real time for later data processing.
