Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping drone technology, and more specifically, to a drone used for surveying and mapping engineering. Background Technology

[0002] In the field of surveying and mapping engineering, drones are important equipment for acquiring geographic information. The stability and adaptability of their camera installation systems directly affect the accuracy of surveying data and work efficiency. However, the drone camera installation systems currently on the market still have many technical defects in practical applications. These problems not only affect the quality of surveying and mapping, but may also lead to equipment damage and reduced work efficiency.

[0003] The primary problem is insufficient adaptability. Existing mounting bracket designs have significant flaws: First, the mounting bracket structure is fixed and lacks versatility; second, the clamping mechanism is singular and cannot adapt to cameras of different specifications. The fixed design not only limits the range of equipment selection, but may also lead to equipment being idle due to model incompatibility. This design deficiency not only reduces the practicality of the equipment, but may also affect the surveying accuracy due to improper installation, increasing the equipment procurement cost and limiting its use.

[0004] More prominently, there are issues with the installation process. The installation and disassembly of some devices present significant problems. The operation requires a variety of specialized tools, the installation steps are cumbersome and complicated, and the disassembly is time-consuming and labor-intensive. In addition, the complex operating procedures not only increase the difficulty of the work, but may also cause equipment damage due to improper operation. This design deficiency not only affects on-site work efficiency, but may also cause safety hazards due to improper installation, thus reducing the practical value of the equipment.

[0005] Most critically, the equipment suffers from poor stability. Although some devices have achieved rapid installation, they have serious problems: First, the simple connection structure makes them prone to loosening due to flight vibrations; second, airflow impacts affect the reliability of the fixation; in addition, structural instability not only affects the shooting quality but may also cause the camera to fall due to fixation failure. This design deficiency not only reduces the accuracy of surveying but may also cause equipment damage due to structural loosening, increasing the risk of operation. Utility Model Content

The installation device includes a clamping plate 2, a mounting frame 3, a screw 4, and a screw sleeve 5. The clamping plate 2 is slidably installed inside the mounting frame 3. The screw 4 is movably connected to the screw sleeve 5 via a thread. The screw 4 is fixedly connected to one side of the clamping plate 2. The screw sleeve 5 is rotatably installed on both sides of the mounting frame 3. A splicing device is provided on one side of the mounting frame 3. The splicing device includes a splicing rod 6, a splicing sleeve 7, an unlocking sleeve 8, a splicing groove 9, a splicing frame 10, and an unlocking groove 11. The splicing sleeve 7 is detachably fitted onto the outside of the splicing rod 6. The unlocking sleeve 8 is rotatably installed on the outside of the splicing sleeve 7. The splicing groove 9 is opened on the outside of the splicing rod 6. The outer wall of the splicing frame 10 is tangent to the inner wall of the unlocking groove 11. The other end of the splicing frame 10 is inserted into... In the splicing slot 9, the unlocking slot 11 is opened inside the unlocking sleeve 8. A limiting mechanism is installed on one side of the unlocking sleeve 8. The limiting mechanism includes a movable spring 12, a moving spring 13, a moving sleeve 14, a moving rod 15, a moving hole 16, a moving plate 17, a moving block 18, and a limiting block 19. The two ends of the movable spring 12 are connected to two adjacent moving blocks 18. The moving sleeve 14 is slidably sleeved on the outside of the splicing sleeve 7. The moving rod 15 is fixedly connected to one side of the moving sleeve 14. The moving hole 16 is opened on the moving plate 17. The moving plate 17 is rotatably installed on the outside of the splicing sleeve 7. The moving spring 13 is sleeved on the outside of the moving rod 15. The other end of the moving spring 13 is in contact with the moving plate 17. Multiple moving blocks 18 are arranged on one side of the unlocking sleeve 8. Multiple limiting blocks 19 are fixedly installed on the outside of the splicing sleeve 7.

[0032] The drone 1 has a detachable mounting bracket 20 at its lower part and a detachable connecting bracket 21 at its upper part.

[0033] Rotating plates 22 are fixed on both sides of the screw sleeve 5.

[0034] In this embodiment, when the camera needs to be installed inside the mounting bracket 3, firstly, the two screw sleeves 5 are rotated in the forward direction by the rotating plate 22, so that the screw sleeves 5 rotate on the side wall of the mounting bracket 3, and the screw 4 does not rotate. Since the screw 4 is movably connected to the screw sleeves 5 by threads, the two screws 4 will drive the two clamping plates 2 to move to both sides. Then, the camera is placed inside the mounting bracket 3. Then, the two screw sleeves 5 are rotated in the reverse direction by the rotating plate 22, and the two screws 4 will drive the two clamping plates 2 to slide inward and in opposite directions, so that the two clamping plates 2 clamp the two sides of the camera, thereby installing the camera inside the mounting bracket 3.

[0035] Please see Figures 3-5 As a further implementation of the overall device: multiple guide rails 23 are fixedly provided on one side of the unlocking sleeve 8, and a guide groove 24 is provided on the inner side of the moving block 18, which is adapted to the guide rails 23.

[0036] One side of the movable block 18 is equipped with a movable wheel 25 that rotates, and the movable wheel 25 is engaged between two corresponding limit blocks 19.

[0037] Limiting block 19 is designed with a cylindrical structure.

[0038] The unlocking slot 11 is a variable diameter structure design.

[0039] A push spring 26 is movably provided on the inner side of the splicing frame 10, and the other end of the push spring 26 is connected to the outer wall of the splicing sleeve 7.

[0040] More specifically, when the mounting bracket 3 needs to be removed because surveying work is no longer required, firstly, rotate the movable plate 17 so that the movable plate 17 drives the movable hole 16 to rotate to a position concentric with the movable rod 15. Then, push the movable sleeve 14 so that the movable sleeve 14 drives the movable rod 15 to slide into the movable hole 16, and the movable sleeve 14 and the movable plate 17 cooperate to compress the movable spring 13. Then, the movable sleeve 14 no longer limits the outer wall of the movable wheel 25. Then, rotate the unlocking sleeve 8 in the forward direction so that the unlocking sleeve 8 drives the movable block 18 to rotate synchronously in the forward direction through the cooperation of the guide rail 23 and the guide groove 24. Then, the movable block 18 drives the movable wheel 25 to roll out between the two limiting blocks 19, and the movable wheel 25 drives the movable block 18 to slide outward along the guide rail 23 and the guide groove 24. Furthermore, the moving block 18 will drive the movable spring 12 to stretch outwards synchronously. At the same time, the unlocking sleeve 8 will drive the unlocking groove 11 opened in the inner diameter-changing structure to rotate in the forward direction. Then, the push spring 26 will push the splicing frame 10 to move outwards, so that one end of the splicing frame 10 gradually slides out of the splicing groove 9, and the outer end of the splicing frame 10 is always in contact with the inner wall of the unlocking groove 11. Then, the splicing sleeve 7 can be removed by pulling it down. Then, follow the above steps to remove the other splicing sleeve 7. Then, the mounting frame 3 can be removed downwards. Then, the connecting frame 21 and the splicing rod 6 can be removed from the inside of the fixed frame 20. When the mounting frame 3 is installed under the UAV 1 for surveying work, first install the connecting frame 21 together with the splicing rod 6 in the corresponding position inside the fixed frame 20. The mounting bracket 3 is then placed on one side of the connecting bracket 21 from below the fixing bracket 20, allowing the splicing rod 6 to pass through the pre-drilled hole on the mounting bracket 3. The splicing sleeve 7 is then directly fitted onto the outside of the splicing rod 6. The unlocking sleeve 8 is then rotated in the opposite direction, causing the unlocking sleeve 8 to drive the guide rail 23 and guide groove 24 to rotate in the opposite direction. Simultaneously, the moving block 18 drives the moving wheel 25 to rotate in the opposite direction. At the same time, the unlocking sleeve 8 drives the unlocking groove 11 on its inner side to rotate in the opposite direction. The inner wall of the unlocking groove 11 then presses against the outer wall of the splicing bracket 10, causing the splicing bracket 10 to press against the push spring 26 again. The other end of the splicing bracket 10 gradually inserts into the splicing groove 9. When the splicing bracket 10 is fully inserted into the splicing groove 9, the unlocking sleeve 8 cannot rotate, and the moving block 18 drives the moving wheel 25 to move to the original two limiting positions. Between the position blocks 19, the movable spring 12 resets and pulls the movable block 18 to slide inward along the guide rail 23 and guide groove 24 to reset. Then, the movable block 18 drives the movable wheel 25 to slide and engage between the original two movable wheels 25. Then, the movable sleeve 14 is released, and the movable spring 13 pushes the movable sleeve 14 to drive the movable rod 15 to slide and reset. When the movable spring 13 is fully reset, the movable plate 17 is rotated, causing the movable hole 16 to rotate to a position that does not correspond to the movable rod 15. Then, the movable rod 15 supports the movable sleeve 14 to one side of the movable plate 17, making the movable sleeve 14 unable to slide. Then, the inner wall of the movable sleeve 14 limits the outer wall of the movable wheel 25, preventing the movable wheel 25 and the movable block 18 from sliding outward, thereby limiting the unlocking sleeve 8 and preventing the unlocking sleeve 8 from rotating.This ensures the stable installation of mounting bracket 3.

[0041] In summary, when using or operating the entire device: When it is necessary to install the camera inside the mounting bracket 3, firstly, rotate the two screw sleeves 5 in the forward direction using the rotating plate 22, so that the screw sleeves 5 rotate on the side wall of the mounting bracket 3, and prevent the screw 4 from rotating. Since the screw 4 is movably connected to the screw sleeves 5 through threads, the two screws 4 will then drive the two clamping plates 2 to move to both sides. Then, place the camera inside the mounting bracket 3. Next, rotate the two screw sleeves 5 in the reverse direction using the rotating plate 22, and the two screws 4 will then drive the two clamping plates 2 to slide inwards and towards each other, so that the two clamping plates 2 clamp the two sides of the camera, thereby installing the camera inside the mounting bracket 3.

[0042] When the mounting bracket 3 needs to be removed because surveying work is no longer required, first rotate the movable plate 17 so that the movable plate 17 drives the movable hole 16 to rotate to a position concentric with the movable rod 15. Then push the movable sleeve 14 so that the movable sleeve 14 drives the movable rod 15 to slide into the movable hole 16, and the movable sleeve 14 and the movable plate 17 cooperate to compress the movable spring 13. Then the movable sleeve 14 no longer limits the outer wall of the movable wheel 25. Then rotate the unlocking sleeve 8 in the forward direction so that the unlocking sleeve 8 drives the movable block 18 to rotate synchronously in the forward direction through the cooperation of the guide rail 23 and the guide groove 24. Then the movable block 18 drives the movable wheel 25 to roll out between the two limiting blocks 19, and the movable wheel 25 drives the movable block 18 to slide outward along the guide rail 23 and the guide groove 24. Block 18 will drive the movable spring 12 to stretch outwards synchronously. At the same time, the unlocking sleeve 8 will drive the unlocking groove 11 opened in the inner diameter-changing structure to rotate in the forward direction. Then, the push spring 26 will push the splicing frame 10 to move outwards, so that one end of the splicing frame 10 gradually slides out of the splicing groove 9, and the outer end of the splicing frame 10 will always be in contact with the inner wall of the unlocking groove 11. Then, the splicing sleeve 7 can be removed by pulling it down. Then, follow the above steps to remove the other splicing sleeve 7. Then, the mounting frame 3 can be removed downwards. Then, the connecting frame 21 and the splicing rod 6 can be removed from the inside of the fixing frame 20. When the mounting frame 3 is to be installed under the UAV 1 for surveying work, first install the connecting frame 21 together with the splicing rod 6 in the corresponding position inside the fixing frame 20. Then, the mounting bracket 3 is placed under the fixed bracket 20 on one side of the connecting bracket 21, so that the splicing rod 6 passes through the pre-drilled hole on the mounting bracket 3. Then, the splicing sleeve 7 is directly fitted onto the outside of the splicing rod 6. Then, the unlocking sleeve 8 is rotated in the opposite direction, so that the unlocking sleeve 8 drives the guide rail 23 and the guide groove 24 to rotate in the opposite direction, and the moving block 18 drives the moving wheel 25 to rotate in the opposite direction. At the same time, the unlocking sleeve 8 drives the unlocking groove 11 opened on the inner side to rotate in the opposite direction. Then, the inner wall of the unlocking groove 11 presses against the outer wall of the splicing bracket 10, so that the splicing bracket 10 presses against the push spring 26 again, and the other end of the splicing bracket 10 gradually gets stuck into the splicing groove 9. When the splicing bracket 10 is fully inserted into the splicing groove 9, the unlocking sleeve 8 cannot rotate, and the moving block 18 drives the moving wheel 25 to move to the original two limit positions. Between blocks 19, the movable spring 12 resets and pulls the movable block 18 to slide inward along the guide rail 23 and guide groove 24 to reset. Then, the movable block 18 drives the movable wheel 25 to slide and engage between the two original movable wheels 25. Then, the movable sleeve 14 is released, and the movable spring 13 pushes the movable sleeve 14 to drive the movable rod 15 to slide and reset. When the movable spring 13 is fully reset, the movable plate 17 is rotated, causing the movable hole 16 to rotate to a position that does not correspond to the movable rod 15. Then, the movable rod 15 supports the movable sleeve 14 to one side of the movable plate 17, making the movable sleeve 14 unable to slide. Then, the inner wall of the movable sleeve 14 limits the outer wall of the movable wheel 25, preventing the movable wheel 25 and the movable block 18 from sliding outward, thereby limiting the unlocking sleeve 8 and preventing the unlocking sleeve 8 from rotating.This ensures the stable installation of mounting bracket 3.
