Description

Technical Field

[0001] The utility model relates to the technical field of unmanned aerial vehicle devices for bridge inspection. More specifically, it relates to an unmanned aerial vehicle device for bridge inspection. Background Art

[0002] In the field of bridge inspection, the application of unmanned aerial vehicle technology is becoming increasingly widespread. It can carry detection equipment such as cameras to efficiently and quickly detect and evaluate the structural safety of bridges. However, there are some obvious deficiencies in the design and use of existing unmanned aerial vehicle detection devices, which limit the application effect of unmanned aerial vehicles in bridge inspection.

[0003] First of all, the existing unmanned aerial vehicle detection devices are relatively simple in structural design, which leads to an important problem: the angle adjustment of the camera is not flexible enough. When conducting bridge inspection, the angle of the camera is crucial for capturing the details of the bridge structure. If the camera angle cannot be adjusted flexibly, it is impossible to effectively photograph all parts of the bridge, especially those areas that are difficult to reach or have limited perspectives. This limitation may result in incomplete or inaccurate detection data, thereby affecting the assessment of the bridge's safety status.

[0004] Secondly, there are inconveniences in the installation of the camera in the existing unmanned aerial vehicle detection devices. When the camera is installed under the unmanned aerial vehicle, the installation and disassembly processes are usually rather cumbersome. This design causes great trouble for the operators when they need to replace the camera model or the unmanned aerial vehicle model. The need for quick equipment replacement is particularly crucial in bridge inspection because different bridges may require different types of cameras to meet the detection requirements. In addition, the inability to quickly disassemble and maintain the camera or the unmanned aerial vehicle not only increases the maintenance cost but also may delay the detection progress due to the long-term downtime of the equipment.

[0005] To solve these problems, some new unmanned aerial vehicle detection devices adopt quick connection mechanisms to facilitate the quick installation and disassembly of the camera. However, the designs of these quick connection mechanisms are usually relatively simple and cannot ensure the stability of the camera after installation. In the actual use process, this design defect may cause the camera to become loose or even fall off, which will not only damage the equipment but also pose a threat to the safety of the unmanned aerial vehicle and the operators. The falling off of the camera during flight may also cause damage to the bridge or other objects below, increasing the risk of accidents. Summary of the Utility Model

[0032] One side of the clamping rod 5 and the clamping sleeve 2 is connected with a clamping plate 17 .

[0033] A limit block 18 is provided in the clamping sleeve 2 , and the limit block 18 is fixedly arranged in the clamping slot 4 .

[0034] A push spring 19 is connected to one side of the matching sleeve 10 , and the other end of the push spring 19 is in contact connection with the movable plate 8 .

[0035] The positioning assembly includes a conical spring 20, an adapter rod 21 and an adapter groove 22. Multiple adapter grooves 22 are opened on the side wall of the clamping rod 5. One end of the adapter rod 21 is connected to the outer wall of the clamping sleeve 2 through the conical spring 20, and the other end of the adapter rod 21 is inserted into the corresponding adapter groove 22.

[0036] In this embodiment, when the camera 23 or the drone 1 needs to be replaced or maintained, the movable plate 8 is first rotated, and the movable plate 8 drives the movable block 13 to move, and then the movable block 13 cooperates with the fixed block 11 to squeeze the spring 12, and at the same time the movable plate 8 drives the clearance groove 9 to move. When the spring 12 is squeezed to the limit, the clearance groove 9 just moves to the position corresponding to the horizontal plate 14, and then the matching sleeve 10 is pushed. The matching sleeve 10 drives the longitudinal plate 7 and the horizontal plate 14 to slide along the slide rail 16 and the slide groove 15, and the matching sleeve 10 drives the longitudinal plate 7 and the horizontal plate 14 to pass through the clearance groove 9, and at the same time the matching sleeve 10 cooperates with the movable plate 8 to squeeze the push spring 19. When the push spring 19 is squeezed to the limit, the corresponding horizontal plate 14 just passes through the clearance groove 9 and moves to On one side of the movable plate 8, then release the movable plate 8, the spring 12 pushes the movable block 13 to drive the movable plate 8 to reset, and the movable plate 8 drives the yield slot 9 to reset and move to a position that no longer corresponds to the transverse plate 14, and then the matching sleeve 10 is engaged with the side of the movable plate 8 through the longitudinal plate 7 and the corresponding transverse plate 14. At this time, the outer side of the adapter rod 21 loses the limit of the matching sleeve 10, and then the mounting sleeve 2 is rotated. The mounting sleeve 2 will drive the adapter rod 21 to move. Due to the rounded structure design at the edge of the adapter groove 22 and the end of the adapter rod 21, and the conical spring 20 is only responsible for providing a weak reset force, the side wall of the adapter groove 22 squeezes the end of the adapter rod 21, so that one end of the adapter rod 21 slides out of the adapter groove 22, and the other end of the adapter rod 21 will drive the conical spring 20 to stretch, and the mounting sleeve 2 drives the card slot 4, the straight slot 6 and the limit block 18 to move, so that the card block 3 slides relatively in the card slot 4. When the other side of the limit block 18 is fitted with one side of the card block 3, the position of the straight slot 6 corresponds to the position of the card block 3. Then, the card rod 5 and the card sleeve 2 are pulled to both sides respectively, so that the card rod 5 drives the card block 3 to enter the straight slot 6 and slide out along the straight slot 6. Then, the card rod 5 will be removed from the card sleeve 2, and at the same time, the conical spring 20 will drive the adapter rod 21 to reset. Then, the camera 23 or the drone 1 is replaced or maintained. After the maintenance or replacement is completed, the card rod 5 is passed through the connecting seat 25 and the connecting frame 24, and the card sleeve 2 is fitted to the outside of the card rod 5 from the other side, so that the card rod 5 drives the card block 3 to slide into the straight slot 6. At the same time, The mounting rod 5 will push the adapter rod 21 open, so that the mounting rod 5 drives the conical spring 20 to stretch again. Then, when one end of the mounting rod 5 is against the inner wall of the mounting sleeve 2, the mounting sleeve 2 is rotated in the opposite direction. The mounting sleeve 2 drives the straight slot 6, the mounting slot 4 and the limit block 18 to move again, so that the mounting block 3 enters the mounting slot 4. When one side of the limit block 18 is in contact with the mounting block 3, the mounting sleeve 2 cannot rotate. At the same time, the conical spring 20 drives the adapter rod 21 to reset, and makes one end of the adapter rod 21 engage in the adapter slot 22. Then the movable plate 8 is rotated again. The movable plate 8 drives the movable block 13 and the fixed block 11 to cooperate to squeeze the spring 12 again. At the same time, the movable plate 8 will drive the give way slot 9 to move. When the spring 12 is squeezed to the limit, the position of the give way slot 9 corresponds to the position of the cross plate 14.Then the push spring 19 pushes the matching sleeve 10 to return along the slide rail 16 and the slide groove 15. At the same time, the matching sleeve 10 drives the longitudinal plate 7 and the transverse plate 14 to return to their original position. Then the outer wall of the matching sleeve 10 will limit the outer side of the adapter rod 21 again, so that the adapter rod 21 and the adapter groove 22 cooperate to limit the mounting rod 5. When the push spring 19 is fully reset, the corresponding two transverse plates 14 are respectively on both sides of the movable plate 8. Then the movable plate 8 is released, and the spring 12 pushes the movable block 13 to drive the movable plate 8 to return to its original position. Then the movable plate 8 drives the resetting groove 9 to return to its original position and moves the resetting groove 9 to a position that does not correspond to the transverse plate 14. The transverse plate 14 and the longitudinal plate 7 cooperate to support and limit the matching sleeve 10, thereby ensuring a stable and fast installation connection.

[0037] See also Figures 1-3 As an implementation method of the adjustment device: the adjustment device includes a camera 23, a connecting frame 24 and a connecting seat 25. The connecting frame 24 is set at the top of the camera 23, and the connecting seat 25 is respectively connected to the bottom of the drone 1 and one side of the camera 23. The camera 23 is rotatably connected through the connecting frame 24 set at the top and a connecting seat 25 set at the bottom of the drone 1.

[0038] A cylinder 26 is provided under the drone 1, and a piston rod 27 is connected to the output end of the cylinder 26. The other ends of the cylinder 26 and the piston rod 27 are connected to a connecting frame 24. The cylinder 26 is rotatably connected to a connecting seat 25 provided under the drone 1 through the connecting frame 24, and the piston rod 27 is rotatably connected to a connecting seat 25 provided on one side of the camera 23 through the connecting frame 24.

[0039] A support leg 28 is connected to the lower portion of the drone 1 , and the support leg 28 is detachably mounted on the lower portion of the drone 1 .

[0040] More specifically, when the angle of the camera 23 needs to be adjusted, the cylinder 26 is driven, and the cylinder 26 drives the piston rod 27 set at the output end to move. Then the piston rod 27 will drive the camera 23 to rotate with the connecting frame 24 set above as the center through one end connected to the connecting frame 24 and the connecting seat 25 set at the side of the camera 23. At the same time, the cylinder 26 will move along the connecting frame 24 connected at one end and the connecting seat 25 set below the drone 1, thereby realizing the adjustment of the angle of the camera 23. After adjusting to the appropriate angle, the cylinder 26 can be closed.

[0041] In summary, when the entire device is in use or running: when the camera 23 or the drone 1 needs to be replaced or maintained, first rotate the movable plate 8, the movable plate 8 drives the movable block 13 to move, and then the movable block 13 will cooperate with the fixed block 11 to squeeze the spring 12, and at the same time the movable plate 8 will drive the clearance groove 9 to move. When the spring 12 is squeezed to the limit, the clearance groove 9 just moves to the position corresponding to the cross plate 14, and then push the matching sleeve 10. The matching sleeve 10 drives the longitudinal plate 7 and the cross plate 14 to slide along the slide rail 16 and the slide groove 15, and the matching sleeve 10 will drive the longitudinal plate 7 and the cross plate 14 to pass through the clearance groove 9. At the same time, the matching sleeve 10 will cooperate with the movable plate 8 to squeeze the push spring 19. When the push spring 19 is squeezed to the limit, the corresponding cross plate 14 just passes through the clearance groove. The movable plate 8 is then released, and the spring 12 pushes the movable block 13 to drive the movable plate 8 to reset. The movable plate 8 drives the positioning slot 9 to reset and move to a position that no longer corresponds to the transverse plate 14. Then the matching sleeve 10 is engaged with the side of the movable plate 8 through the longitudinal plate 7 and the corresponding transverse plate 14. At this time, the outer side of the adapter rod 21 loses the limit of the matching sleeve 10, and then the mounting sleeve 2 is rotated. The mounting sleeve 2 will drive the adapter rod 21 to move. Due to the rounded structure design at the edge of the adapter groove 22 and the end of the adapter rod 21, and the conical spring 20 is only responsible for providing a weak reset force, the side wall of the adapter groove 22 squeezes the end of the adapter rod 21, causing one end of the adapter rod 21 to slide out of the adapter groove 22, and the other end of the adapter rod 21 will drive the conical spring 20 to stretch. When the fixing sleeve 2 is in contact with the fixing block 3, the fixing block 3 is moved into the fixing slot 4. When the fixing block 3 is in contact with the fixing block 3, the fixing rod 5 and the fixing sleeve 2 are pulled to the sides respectively, so that the fixing rod 5 drives the fixing block 3 to enter the straight slot 6 and slide out along the straight slot 6. Then the fixing rod 5 is removed from the fixing sleeve 2, and the conical spring 20 drives the adapter rod 21 to reset. Then the camera 23 or the drone 1 is replaced or maintained. After the maintenance or replacement is completed, the fixing rod 5 is passed through the connecting seat 25 and the connecting frame 24, and the fixing sleeve 2 is fitted to the outside of the fixing rod 5 from the other side, so that the fixing rod 5 drives the fixing block 3 to slide into the straight slot 6. At the same time, the mounting rod 5 will push the adapter rod 21 open, so that the mounting rod 5 drives the conical spring 20 to stretch again. Then, when one end of the mounting rod 5 is against the inner wall of the mounting sleeve 2, the mounting sleeve 2 is rotated in the opposite direction. The mounting sleeve 2 drives the straight slot 6, the mounting slot 4 and the limit block 18 to move again, so that the mounting block 3 enters the mounting slot 4. When one side of the limit block 18 is in contact with the mounting block 3, the mounting sleeve 2 cannot be rotated. At the same time, the conical spring 20 drives the adapter rod 21 to reset, and makes one end of the adapter rod 21 engage in the adapter slot 22. Then the movable plate 8 is rotated again. The movable plate 8 drives the movable block 13 and the fixed block 11 to cooperate to squeeze the spring 12 again. At the same time, the movable plate 8 will drive the give way slot 9 to move. When the spring 12 is squeezed to the limit, the position of the give way slot 9 corresponds to the position of the cross plate 14.Then the push spring 19 pushes the matching sleeve 10 to return along the slide rail 16 and the slide groove 15. At the same time, the matching sleeve 10 drives the longitudinal plate 7 and the transverse plate 14 to return to their original position. Then the outer wall of the matching sleeve 10 will limit the outer side of the adapter rod 21 again, so that the adapter rod 21 and the adapter groove 22 cooperate to limit the mounting rod 5. When the push spring 19 is fully reset, the corresponding two transverse plates 14 are respectively on both sides of the movable plate 8. Then the movable plate 8 is released, and the spring 12 pushes the movable block 13 to drive the movable plate 8 to return to its original position. Then the movable plate 8 drives the resetting groove 9 to return to its original position and moves the resetting groove 9 to a position that does not correspond to the transverse plate 14. The transverse plate 14 and the longitudinal plate 7 cooperate to support and limit the matching sleeve 10, thereby ensuring a stable and fast installation connection.

[0042] When the angle of the camera 23 needs to be adjusted, the cylinder 26 is driven, and the cylinder 26 drives the piston rod 27 set at the output end to move. Then the piston rod 27 will drive the camera 23 to rotate with the connecting frame 24 set above as the center through one end connected to the connecting frame 24 and the connecting seat 25 set at the side of the camera 23. At the same time, the cylinder 26 will move along the connecting frame 24 connected at one end and the connecting seat 25 set at the bottom of the drone 1, thereby realizing the adjustment of the angle of the camera 23. After adjusting to the appropriate angle, the cylinder 26 can be closed.

[0043] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded.
