Description

Technical Field

[0001] The present invention belongs to the technical field of unmanned aerial vehicle (UAV) transportation, and in particular relates to a multifunctional marine transport UAV. Background Art

[0002] With the advancement of intelligent maritime transport operations, drones are increasingly being used in scenarios such as ship cargo transfer, emergency rescue, and equipment lifting. This is particularly true in marine environments where ships cannot berth at their destinations. This poses a significant challenge to the safe and efficient transfer of heavy / critical equipment (such as energy storage batteries, solar panels, and navigation lights used by marine beacons). Traditional lifting equipment is bulky and sluggish, so the development of drones with lifting capabilities is crucial for improving the stability and flexibility of specialized cargo transfers at sea.

[0021] The following embodiments are for illustration only and can be combined with each other, and are not limited to the contents presented in the following single embodiments.

[0022] The present invention provides a multifunctional marine transport drone, such as Figure 1 and Figure 2 As shown, it includes a drone body 1, a rotating rod structure and a suspension structure; the drone body 1 includes a supporting base plate 11, the supporting base plate 11 is fixed to the bottom of the drone body 1, and a circular ring groove 12 is opened on the supporting base plate 11; the rotating rod structure has four rods, refer to Figure 4 and Figure 6 , the rotating rod structure includes a support rod 21 and a rotation drive motor 22, the ends of the four support rods 21 are coaxially rotatably arranged on the support base plate 11, the rotating shaft of the support rod 21 is coaxially arranged with the annular groove 12, the rotation drive motor 22 is fixed to the top side of the middle part of the support rod 21, and the output end of the rotation drive motor 22 is provided with a gear that meshes with the side wall of the annular groove 12. Furthermore, in order to improve the carrying capacity of the support rod 21, a T-head bearing pin 212 is also provided on the top of the support rod 21, and a bearing ring 13 with a T-shaped cross-section is provided on the support base plate 11, and the bearing pin is slidably arranged in the bearing ring 13; reference Figure 4 The suspension structure includes a suspension rope 31, a hook 32 and a mobile car 33. The mobile car 33 is arranged to move along the bottom of the support rod 21. The suspension rope 31 extends from the bottom of the mobile car 33. The hook 32 is fixed to the end of the suspension rope 31. Figure 3 and Figure 9 As shown, the mobile vehicle 33 includes a vehicle body 331, a mobile drive motor 332 and a worm gear structure 333. A slide groove 211 with a T-shaped cross section is provided at the bottom of the support rod 21. The vehicle body 331 is movably set on the slide groove 211. A rack is provided on the top surface of the slide groove 211. The mobile drive motor 332 is installed in the vehicle body 331. The mobile drive motor 332 is engaged with the rack on the top surface of the slide groove 211 through the worm gear structure 333. The worm gear structure 333 can ensure that the mobile vehicle 33 is driven by the mobile drive motor 332 to move along the support rod 21, and will not slip due to the lateral force of the suspension rope 31 during the suspension process. In order to avoid interference between the suspension rope 31 and the mobile vehicle 33, a rope groove is also provided on the top of the slide groove 211, and the suspension rope 31 is embedded in the rope groove.

[0023] In this scheme, by setting four coaxially rotating support rods 21, under the drive of the rotating drive motor 22, the gear of the rotating drive motor 22 is engaged with the swivel 24 for transmission, respectively driving each support rod 21 to rotate a certain angle under the support base 11, and the mobile vehicle 33 moves along the support rod 21 to adjust the position of the suspension rope 31 extending from the support rod 21. The four hooks 32 can be combined to form four suspension points in different positions under the rotation of the support rod 21 and the movement adjustment of the mobile vehicle 33 to adapt to the suspension of square boxes of different shapes and sizes and provide stable suspension for the boxes; this drone is used to adjust the four suspension points in time during the transportation and transfer of navigation equipment on the ship, so that the drone can perform multi-point suspension of navigation equipment of different sizes and shapes, ensuring that the navigation equipment is quickly positioned and stably lifted. Compared with ordinary suspension drones, the suspension structure of this drone is convenient and fast to adjust, has strong adaptability and excellent stability, making the marine navigation equipment more stable during transportation and transfer.

[0024] In a further solution, Figure 4 and Figure 5 As shown, the rotating rod structure also includes a rotating column 23 and three rotating rings 24. The top end of the rotating column 23 is rotatably set on the supporting base plate 11. The three rotating rings 24 are arranged vertically and are coaxially rotatably set on the rotating column 23 in sequence. The end of one of the support rods 21 is fixedly connected to the rotating column 23, and the other three support rods 21 are fixedly connected to the three rotating rings 24 respectively; on the support rod 21 fixedly connected to the rotating column 23, the mobile vehicle 33 can be moved to the center of the rotating column 23.

[0025] In this structure, one of the four support rods 21 is connected to the rotating column 23, so that the mobile vehicle 33 can move along the support rod 21 to the center of the rotating column 23, and the other three support rods 21 balance the center of gravity of the drone by rotating, so that the drone is adjusted to a single-rope suspension mode, which is suitable for lighter objects at sea, such as the transportation and transfer of navigation lights. In this structure, the single-rope suspension position is in the middle of the bottom of the drone, so that the drone has a stable center of gravity when suspending lighter objects, enabling it to transport objects over longer distances.

[0026] In a further solution, Figure 5 As shown, the rotating rod structure also includes a telescopic cylinder 25, which is installed on the rotating column 23. A pin 26 is fixed to the end of the telescopic cylinder 25. A pin hole is provided at the top of the mobile car 33 on the support rod 21 fixedly connected to the rotating column 23. When the mobile car 33 moves to the center of the rotating column 23, the pin 26 can be inserted into the pin hole of the mobile car 33.

[0027] By setting a pin 26 and a pin hole structure at the center of the rotating column 23, when the mobile vehicle 33 moves to the center of the rotating column 23, the mobile vehicle 33 is fixed on the support rod 21 by the pin 26, thereby limiting the shaking of the mobile vehicle 33 on the support rod 21, avoiding the wear of the internal transmission components of the mobile vehicle 33 due to the shaking of the suspended object during the single-point suspension process, and providing a more stable suspension structure for the drone in the single-point suspension mode.

[0028] In a further solution, Figure 4 、 Figure 7 and Figure 8 As shown, the rotating rod structure also includes a wire-taking structure, which is arranged inside the support rod 21, and the suspension rope 31 is wound by the wire-taking structure. The suspension rope 31 extends from the free end of the support rod 21 and passes through the mobile vehicle 33, and is finally connected to the hook 32. The wire-taking structure includes two traction devices 34, and the traction device 34 includes a traction drive motor 341, a screw 342 and a moving seat 343. A rope bin 213 and a traction bin 214 are arranged side by side in the support rod 21. The screw 342 is arranged up and down and is rotatably arranged in the traction bin 214. The traction The driving motor 341 drives the lead screw 342 to rotate, the movable seat 343 is threadedly connected to the lead screw 342 and is laterally movable in the traction bin 214, a traction pin 344 is fixedly provided on the side of the movable seat 343, the traction pin 344 passes through the rope bin 213 from the traction bin 214, a fixed pin 215 is fixed in the rope bin 213, the fixed pin 215 is located between the traction pins 344 set in the upper and lower positions, the suspension rope 31 passes through the outside of the support rod 21 and is fixed to the top of the rope bin 213, the traction pin 344 and the fixed pin 215 are respectively located on both sides of the suspension rope 31.

[0029] The two traction pins 344 can be reeled in by the two movable seats 343 through the blocking of the fixed pins 215. The two traction pins 344 can reel in the length of the suspension rope 31. This reeling structure can adjust the extended length of the suspension rope 31. In the four-point suspension mode, the suspension height of the four points can be adjusted to adapt to the suspension points of the suspended object so that the suspended object maintains the required angle during the suspension process. In the single-point suspension mode, the suspension height of the suspended object can be adjusted to avoid transportation swaying caused by excessive suspension length. The multi-pin reeling structure set in this structure avoids slippage of the suspension rope 31 during the suspension process compared to the winding reeling structure. The length of the suspension rope 31 can be adjusted accurately and the suspension point can be adjusted accurately.

[0030] In a further solution, Figure 9 As shown, the suspension structure also includes a magnetic structure, which includes an upper seat 351 and a lower seat 352. The upper seat 351 is rotatably set at the bottom of the mobile vehicle 33, and the lower seat 352 is fixedly connected to the hook 32. The bottom surface of the upper seat 351 and the top surface of the lower seat 352 are respectively provided with semicircular magnets. The mobile vehicle 33 also includes a magnetic drive motor 334, and the end of the magnetic drive motor 334 is provided with a gear engaged with the lower seat 352. As the take-up structure is recovered, the upper seat 351 is magnetically connected to the lower seat 352, and the position of the hook 32 can be adjusted by rotating the magnetic drive motor 334.

[0031] In this structure, when the drone suspends an object, the reeling structure is recovered to bring the lower seat 352 and the upper seat 351 closer together. Under the magnetic attraction of the semicircular magnet, the upper seat 351 and the lower seat 352 attract each other at a fixed angle. Under the rotation of the magnetic drive motor 334, the hanging point direction of the hook 32 can be adjusted. During the suspension process, the drone can be remotely controlled to move and hang the object.

[0032] In a further solution, Figure 4 As shown, the rotating rod structure further includes a supporting foot 27 , which is fixed to the rotating free end of the supporting rod 21 and extends obliquely downward.

[0033] In this solution, support legs 27 are provided to provide the drone with a platform parking capability when there is no suspension.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
