Description

Technical Field

[0001] This utility model relates to the field of bridge crack detection technology, specifically a drone scanning device for detecting bridge cracks. Background Technology

[0002] The UAV scanning device for detecting bridge cracks is an intelligent detection system that combines UAV technology with high-precision sensing equipment. It is used to quickly and safely identify defects such as cracks, spalling, and corrosion on bridge surfaces. While the UAV scanning device captures crack details using a camera, it has limitations in narrow spaces such as inside box girders, behind piers, and under expansion joints, where the camera cannot directly access these areas. Therefore, we propose a UAV scanning device for detecting bridge cracks. Utility Model Content

[0003] The present invention aims to solve the problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a scanning device for detecting bridge cracks using an unmanned aerial vehicle (UAV), comprising a body, a linear motion component, and a front moving seat. The top of the body is provided with a slot. The linear motion component includes a mounting plate inserted into the slot, a limiting hole opened on the mounting plate, a frame fixedly mounted on the top of the mounting plate, a lead screw connected to the frame bearing, a first gear fixedly mounted on the lead screw, a second gear meshing with the first gear, and a drive motor fixedly connected to the second gear. The front moving seat is threadedly connected to the lead screw, and a rotary motor is provided on the front moving seat. A camera is fixed to the output end of the rotary motor.

[0005] Preferably, the exterior of the machine body is fixed with several arms, and each of the arms is fixed with a propeller.

[0006] Preferably, the lead screw has external threads in different directions at its front and rear ends.

[0007] Preferably, it also includes a rear movable seat, which is threadedly connected to the lead screw, and a weight is fixed to the top of the rear movable seat.

[0008] Preferably, it also includes a fastening assembly, which includes a T-shaped column fixedly disposed at the top of the machine body, a rotating plate rotatably connected to the T-shaped column, a fastening rod inserted through the rotating plate, and a spring disposed on the fastening rod and the rotating plate.

[0009] Preferably, two adjacent fastening components form a group, and two groups are arranged symmetrically.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: The drive motor of this utility model can drive the lead screw through the first gear and the second gear, so that the front moving seat and the rear moving seat move away from each other, thereby adjusting the position of the camera and the weight block. After adjustment, the camera can be moved to a narrow space, and the set rotary motor can drive the camera to rotate in order to capture crack details, thus having a wide range of applications. At the same time, the weight block can increase the weight of the rear of the linear movement component to maintain balance. Then, the set spring has a certain elastic potential energy, which allows the fastening rod to move away from the limiting hole of the mounting plate. After it moves away, the rotating plate can be rotated and no longer obstructs the mounting plate, so the linear movement component can be directly disassembled for use. Attached Figure Description

In use, the linear motion component 200 can be fixed through the slot 103. The arms 101 are used to support and fix the propeller 102, and the propeller 102 can rotate at high speed so that the fuselage 100 can take off.

[0027] Specifically, the linear motion assembly 200 includes a mounting plate 206 inserted into the slot 103, a limiting hole 2061 opened on the mounting plate 206, a frame 201 fixedly mounted on the top of the mounting plate 206, a lead screw 202 connected to the frame 201 by a bearing, a first gear 203 fixedly mounted on the lead screw 202, a second gear 204 meshing with the first gear 203, and a drive motor 205 fixedly connected to the second gear 204. The front and rear parts of the lead screw 202 are provided with external threads in different directions. In use, the mounting plate 206 can increase the contact area between the linear motion assembly 200 and the machine body 100 for fixing, while the limiting hole 2061 has a limiting effect to fix the assembly 500. The drive motor 205 can drive the first gear 203, the second gear 204 and the lead screw 202 to rotate, so that the lead screw 202 can push the front moving seat 300 to move, thereby adjusting the position of the camera 301 so that the camera 301 can be moved into narrow spaces.

[0028] Specifically, the front moving base 300 is threaded onto the lead screw 202. A rotary motor 302 is installed on the front moving base 300. A camera 301 is fixed to the output end of the rotary motor 302. In use, the front moving base 300 can drive the camera 301 to move so that the camera 301 can move into a narrow space to capture crack details. The rotary motor 302 can drive the camera 301 to rotate so that the angle of the camera 301 can be adjusted.

[0029] Example 2:

[0030] Reference Figure 1 and Figure 3 This is the second embodiment of the present invention, which differs from the first embodiment in that it also includes a rear movable seat 400, which is threadedly connected to the lead screw 202. A weight block 401 is fixed to the top of the rear movable seat 400. In use, the rear movable seat 400 and the weight block 401 can be moved by the lead screw 202. The weight block 401 can be symmetrical with the camera 301. The weight block 401 can increase the weight of the rear of the linear motion component 200 in order to maintain balance.

[0031] Example 3:

[0032] Reference Figure 1 and Figure 5 This is the third embodiment of the present invention, which differs from the previous two embodiments in that it also includes a fastening assembly 500. The fastening assembly 500 includes a T-shaped column 501 fixedly installed at the top of the body 100, a rotating plate 502 rotatably connected to the T-shaped column 501, a fastening rod 503 inserted on the rotating plate 502, and a spring 504 installed on the fastening rod 503 and the rotating plate 502. Two adjacent fastening assemblies 500 form a group, and two groups are symmetrically arranged. In use, the spring 504 makes the fastening rod 503 movable so that the fastening rod 503 can disengage from the limiting hole 2061. After disengagement, the rotating plate 502 can be rotated to no longer block the mounting plate 206, so as to quickly disassemble the linear movement assembly 200.

[0033] The working principle and usage process of this utility model are as follows: In use, the mounting plate 206 can be inserted into the slot 103, then the fastening rod 503 can be pulled to a suitable height, and the rotating plate 502 can be rotated until the bottom of the fastening rod 503 is aligned with the limiting hole 2061 of the mounting plate 206. Then the fastening rod 503 can be released. After release, the fastening rod 503 can be inserted into the limiting hole 2061, thus fixing the linear movement component 200 on the machine body 100. Then the drive motor 205 is controlled to run. The running drive motor 205 will drive the lead screw 202 to rotate through the first gear 203 and the second gear 204. The rotating lead screw 202 will push the front moving seat 300 and the rear moving seat 400 to move away from each other. After moving to a suitable position, the rotary motor 302 can be controlled to run. The running rotary motor 302 can drive the camera 301 to rotate, thus capturing the details of the crack.
