Description

A drone-based bridge crack detection scanner Technical Field

[0001] This utility model relates to the field of bridge inspection technology, specifically to a drone-based bridge crack scanner. Background Technology

[0002] A bridge crack scanner is a specialized device used to detect cracks in bridges. It is mainly used to measure the width of cracks in structures such as bridges, tunnels, buildings, concrete pavements, and metal surfaces, helping engineers and inspectors to detect and address crack problems in a timely manner. A drone-based bridge crack scanner is a detection tool that combines drone technology with multiple sensor devices, primarily used for the detection and identification of bridge cracks.

[0003] Chinese Utility Model Patent Publication No. CN206330924U discloses a drone-based bridge crack detection scanner. This scanner utilizes an infrared distance sensor mounted on the drone to control the distance between the drone and the bridge during flight, preventing damage from excessively close proximity and inaccurate detection from excessively far distances. It also incorporates an infrared thermal imager to detect cracks in the areas the drone flies over. However, this drone-based bridge crack detection scanner lacks an angle adjustment mechanism for the scanner body, making it difficult to adjust the scanning angle and limiting the imaging range. Furthermore, it lacks a quick-installation structure for the scanner body, hindering rapid assembly and disassembly during use, resulting in poor practicality and limiting its widespread adoption. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a UAV bridge crack detection scanner. It can effectively solve the problems of existing technologies that do not have an angle adjustment mechanism for the crack scanner body, making it inconvenient to adjust the shooting angle of the crack scanner body, resulting in a small shooting range. Furthermore, the lack of a quick installation structure for the crack scanner body makes it inconvenient to quickly disassemble and assemble during use or assembly, resulting in poor practicality and difficulty in promoting its use.

[0005] The technical solution adopted by this utility model is as follows: a UAV bridge crack detection scanner, including a UAV body, a fixed rod fixedly installed at the front end of the UAV body, and a support leg fixedly installed at the bottom end of the UAV body.

A second motor is fixedly installed at the end of the mounting frame away from the motor. A second mounting plate is fixedly installed at the output end of the second motor. A guide block is fixedly installed at the end of the second mounting plate away from the second motor. A guide groove is provided on the side of the mounting frame away from the second motor. The crack scanner body is provided on the outer wall of the second mounting plate.

[0006] Preferably, the outer wall of the support leg is attached with a cushioning pad, the cross-section of the support leg is a "T" shaped structure, and two identical support legs are provided, which are symmetrically distributed about the center line of the UAV body.

[0007] The above technical solution improves the stability of the drone when landing by designing support legs, and reduces wear and tear on the support legs by designing cushioning pads, thus extending their service life. It is highly practical.

[0009] Using the above technical solution, the staff will attach the installation sleeve to the outside of the fixing rod and insert the positioning block into the positioning groove, which can achieve rapid positioning of the installation sleeve.

[0010] Preferably, the bolt extends through the second threaded hole into the interior of the first threaded hole, and the second threaded hole has the same diameter as the first threaded hole.

[0011] With the above technical solution, after the mounting sleeve is quickly positioned, the staff can insert the bolt through the threaded hole 2 and extend it into the inside of the threaded hole 1, which can realize the quick positioning of the mounting sleeve. After long-term use, it is convenient to inspect or replace it.

[0012] Preferably, the first guide block and the first guide groove are slidably connected, and the second guide block and the second guide groove are slidably connected.

[0013] With the above technical solution, the operator starts motor one, and the output shaft of motor one rotates, driving the mounting bracket to rotate, which in turn drives the crack scanner body to rotate, thus enabling the horizontal shooting angle adjustment of the crack scanner body. At the same time, the operator starts motor two, and the output shaft of motor two rotates, driving the mounting plate two to rotate, which in turn drives the crack scanner body to rotate, thus enabling the tilt angle adjustment of the crack scanner body and increasing the shooting range of the crack scanner body. It has high practicality.

[0014] Preferably, the outer arm of the mounting plate two is provided with a positioning groove two and a sliding groove. An insert block is fixedly installed on the inner side of the positioning groove two. A limit block is slidably connected to the inner side of the sliding groove.

Embodiments

[0030] As shown in Figures 1-7, the present invention provides a UAV bridge crack detection scanner, including a UAV body 1, a fixing rod 2 fixedly installed at the front end of the UAV body 1, and a support leg 3 fixedly installed at the bottom end of the UAV body 1. A mounting sleeve 7 is provided at the end of the fixing rod 2 away from the UAV body 1. A mounting plate 11 is fixedly installed between the two mounting sleeves 7. A motor 12 is fixedly installed on the side of the mounting plate 11 away from the support leg 3. A mounting frame 13 is fixedly installed at the output end of the motor 12. A guide groove 14 is provided at the end of the mounting frame 13 near the motor 12. A guide block 15 is fixedly installed on the side of the mounting plate 11 near the mounting frame 13. A motor 26 is fixedly installed at the end of the mounting frame 13 away from the motor 12. A mounting plate 27 is fixedly installed at the output end of the motor 26. A guide block 28 is fixedly installed at the end of the mounting plate 27 away from the motor 26. A guide groove 29 is provided on the side of the mounting frame 13 away from the motor 26. A crack scanner body 25 is provided on the outer wall of the mounting plate 27.

[0031] Specifically, a buffer pad 4 is attached to the outer wall of the support leg 3. The cross-section of the support leg 3 is T-shaped, and two identical support legs 3 are provided, symmetrically distributed about the center line of the drone body 1. The advantages are that the design of the support leg 3 improves the stability of the drone body 1 when landing, and the design of the buffer pad 4 reduces the wear of the support leg 3, increases its service life, and makes it highly practical.

[0032] Specifically, the end of the fixing rod 2 furthest from the drone body 1 has a positioning groove 5 and a threaded hole 6. A positioning block 8 is fixedly installed on the inner wall of the mounting sleeve 7, and a threaded hole 9 is provided on the outer wall of the mounting sleeve 7. A bolt 10, compatible with threaded holes 9 and 6, is threaded onto the outer wall of the mounting sleeve 7. The mounting sleeve 7 is compatible with the fixing rod 2, and the positioning block 8 is inserted into the positioning groove 5. The advantage is that the operator can quickly position the mounting sleeve 7 by placing it on the outside of the fixing rod 2 and simultaneously inserting the positioning block 8 into the positioning groove 5.

[0033] Specifically, bolt 10 extends through threaded hole 9 into the interior of threaded hole 6, and threaded hole 9 has the same diameter as threaded hole 6. The advantage is that after quickly positioning the mounting sleeve 7, the operator can quickly limit the positioning of the mounting sleeve 7 by extending bolt 10 through threaded hole 9 into the interior of threaded hole 6. This also facilitates maintenance or replacement after prolonged use. Example

[0034] As shown in Figures 2-7, as an improvement on the previous embodiment, to further facilitate the installation of the crack scanner body 25, specifically, the outer arm of the mounting plate 2 17 is provided with a positioning groove 20 and a sliding groove 21. An insert block 22 is fixedly installed on the inner side of the positioning groove 20, and a limiting block 23 is slidably connected to the inner side of the sliding groove 21. A buckle 24 is fixedly installed on the outer wall of the limiting block 23. The outer edge of the crack scanner body 25 is provided with a slot 26, a limiting groove 27, and a locking groove 28. The crack scanner body 25 is adapted to the positioning groove 20, and the insert block 22 and the slot 26 are plugged into each other. The advantage is that the operator can quickly position the crack scanner body 25 by inserting it into the positioning groove 20 and simultaneously inserting the insert block 22 into the slot 26.

[0035] Specifically, the slide groove 21, the limiting groove 27, and the locking groove 28 are interconnected. The limiting block 23 is adapted to the limiting groove 27, and the latch 24 is adapted to the locking groove 28. The advantage is that after quickly positioning the crack scanner body 25, the operator slides the limiting block 23 into the limiting groove 27. When the latch 24 contacts the crack scanner body 25, the latch 24 deforms. When the limiting block 23 is completely submerged in the limiting groove 27, the latch 24 returns to its original shape, allowing it to engage with the locking groove 28. This enables rapid positioning of the crack scanner body 25, facilitating quick assembly and disassembly during use or assembly, and making it highly practical.

[0036] Specifically, guide block 15 and guide groove 14 are slidably connected, and guide block 2 18 and guide groove 2 19 are slidably connected. The advantage is that when the operator starts motor 12, the output shaft of motor 12 rotates, driving the mounting bracket 13 to rotate, which in turn drives the crack scanner body 25 to rotate, allowing adjustment of the horizontal shooting angle of the crack scanner body 25. Simultaneously, when the operator starts motor 2 16, the output shaft of motor 2 16 rotates, driving the mounting plate 2 17 to rotate, which in turn drives the crack scanner body 25 to rotate, allowing adjustment of the tilt angle of the crack scanner body 25, thus increasing the shooting range of the crack scanner body 25 and making it highly practical.

[0037] Working principle: During installation, the operator places the mounting sleeve 7 onto the outside of the fixing rod 2, and simultaneously inserts the positioning block 8 into the positioning groove 5, which enables quick positioning of the mounting sleeve 7. After quick positioning of the mounting sleeve 7, the operator inserts the bolt 10 through the threaded hole 9 into the threaded hole 6, which enables quick limiting of the mounting sleeve 7, facilitating maintenance or replacement after prolonged use. Subsequently, the operator inserts the crack scanner body 25 into the positioning groove 20, and simultaneously inserts the insert block 22 into the slot 26, which enables quick positioning of the crack scanner body 25. After quick positioning of the crack scanner body 25, the operator slides the limiting block 23 into the limiting groove 27. When the latch 24 contacts the crack scanner body 25, the latch 24 deforms. When the limiting block 23 is completely submerged in the limiting groove 27, the latch 24 returns to its original shape, thus locking the latch 25. 4. The slot 28 allows for quick positioning of the crack scanner body 25, facilitating rapid assembly and disassembly during use or assembly, thus offering high practicality. During use, the operator activates motor 12, whose output shaft rotates, driving the mounting bracket 13 to rotate, which in turn rotates the crack scanner body 25, allowing for horizontal adjustment of the shooting angle. Simultaneously, the operator activates motor 26, whose output shaft rotates, driving the mounting plate 27 to rotate, which in turn rotates the crack scanner body 25, allowing for tilt adjustment of the crack scanner body 25 and increasing its shooting range, further enhancing its practicality. During landing, the support legs 3 improve the stability of the drone body 1 upon landing, while the buffer pads 4 reduce wear on the support legs 3, extending their lifespan, further contributing to its practicality.
