To be clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work indicate or imply relative importance or implicitly indicate the number of indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0026] Existing drone transport systems have a simple structure, using claws and clamps to secure cargo. These are only suitable for clamping and securing square cargo. In actual applications, cargo often has a variety of shapes, including cylindrical, conical, and other structures. Therefore, when clamping and securing cargo, the contact area between the claws and the outer walls of these non-square cargo is small, resulting in poor stability and security in securing the cargo. To address the above technical issues, this case proposes the following technical solutions:

[0027] Reference Figures 1 to 6 As shown, a multifunctional intelligent drone, its structure includes: a drone body 1, a cargo supporting device 2 fixed to the bottom of the drone body 1, and a supporting device 3 installed on the cargo supporting device 2, the cargo supporting device 2 includes a fixed beam 21 arranged at the bottom of the drone body 1, the bottom of the fixed beam 21 has two cross bars 22 arranged parallel to each other, and each cross bar 22 has a clamping block 23 slidably connected at both ends of the bottom, the cross bar 22 is provided with a first slide groove 24 that cooperates with the clamping block 23, the clamping block 23 is fixed under the cross bar 22 by a first locking bolt 25, and the bottom of the clamping block 23 is rotatably connected to a reel 26, one end of the reel 26 passes through the outer wall of the clamping block 23 and is provided with a handwheel 27, and the other end passes through the outer wall of the clamping block 23 and is provided with a ratchet mechanism 28, a fixing belt 29 is further provided under the cross bar 22, and the two ends of the fixing belt 29 are respectively wound around the surface of the reel 26 in the two clamping blocks 23 under the same cross bar 22;

[0028] Therefore, when using the drone to transport special-shaped objects such as cylindrical or conical objects, first loosen the first locking bolt 25 to drive the clamping block 23 to slide along the first slide groove 24, so that the clamping blocks 23 at both ends of the cross bar 22 contact and clamp the surface of the special-shaped object. After clamping, tighten the first locking bolt 25 to prevent the clamping block 23 from sliding. Then, turn the hand wheel 27 to drive the reel 26 on the clamping block 23 to rotate and reel in the fixing belt 29, so that the fixing belt 2 9 is tightened and fits together with the bottom of the special-shaped object. The ratchet mechanism 28 plays the role of fixing the reel 26 to prevent the reel 26 from rotating reversely after tightening the fixing belt 29, which causes the fixing belt 29 to become loose. Therefore, the two sets of clamping blocks 23 are used to clamp and fix the head and tail ends of the special-shaped object respectively. At the same time, the tightening fixing belt 29 has a supporting effect on the bottom of the special-shaped object, ensuring that objects of different shapes will not move, slide or tilt during transportation, thereby greatly improving the stability and safety of transportation.

[0029] In order to further improve the stability and safety of transportation, the surface of the fixing belt 29 is provided with a diagonal pattern, which effectively increases the friction between the fixing belt and the surface of the special-shaped object, thereby preventing the object from sliding or shifting during transportation.

[0030] Specifically, the ratchet mechanism 28 includes an annular frame 281 fixed to the clamping block 23 and coaxially arranged with the reel 26. A ratchet 282 coaxially connected to the reel 26 is rotatably connected within the annular frame 281. A plurality of ratchet grooves 283 are equidistantly arranged on the ratchet 282. A transmission rod 284 is connected to the top of the annular frame 281. A pull block 285 is provided on the top of the transmission rod 284. A latching tooth 286 that cooperates with the ratchet groove 283 is provided at the bottom of the transmission rod 284. The latching tooth 286 has a smooth inclined surface facing the ratchet 282. A return spring 287 is also sleeved on the outside of the transmission rod 284 to push the latching tooth 286 into the ratchet groove 283.

[0031] Therefore, when in use, the reel 26 is driven to rotate by the hand wheel 27, and then the reel 26 reels the fixing belt 29. During the rotation of the reel 26, the ratchet 282 rotates synchronously, and during the rotation of the ratchet 282, the ratchet 282 rotates along the smooth inclined surface of the latching tooth 286, thereby pushing the latching tooth 286 and the extrusion return spring 287 to drive the transmission rod 284 to move upward. As the ratchet 282 corresponds to the next ratchet groove 283, the return spring 287 pushes the latching tooth 286 into the ratchet groove 283, thereby forming a self-locking state, preventing the ratchet 282 from reversing, ensuring that the fixing belt 29 remains tightened, enhancing the stability of the article, and ensuring that the article will not shake up and down or deviate during transportation;

[0032] When the item needs to be unloaded, the pull block 285 is pulled up, and then the pull block 285 drives the latch 286 through the transmission rod 284 to squeeze the return spring 287 and move up, so that the latch 286 is separated from the ratchet groove 283, and the ratchet 282 can be reversed. At this time, the reverse reel 26 is reversed, the fixing belt 29 can be loosened, and the first locking bolt 25 is loosened at the same time, and the clamping block 23 is pushed to separate from the item, so that the item can be removed, and the loading and unloading operation is simple.

[0033] Furthermore, the reel 26 is penetrated by a mounting hole 261 for the fixing belt 29 to pass through, and the reel 26 is provided with a fastening bolt 262 for locking the fixing belt 29 in the mounting hole 261. Therefore, when in use, one end of the fixing belt 29 is first inserted into the mounting hole 261, and the fixing belt 29 is locked and fixed in the mounting hole 261 by the fastening bolt 262, preventing the fixing belt 29 from sliding or loosening during the rotation of the reel 26, thereby ensuring the firm fixation of special-shaped objects and preventing the safety of the objects from being affected by the loosening of the fixing belt 29.

[0034] Among them, a slide 221 is provided in the middle of the top of the cross bar 22, and the fixed beam 21 is provided with a second slide groove 211 for the slide 221 to slide along the length direction of the fixed beam 21. The slide 221 is fixedly connected to the fixed beam 21 by a second locking bolt 222. Therefore, when clamping and fixing the object, the second locking bolt 222 can be loosened to drive the slide 221 to slide along the second slide groove 211, and the second locking bolt 222 can be tightened after the sliding is completed; thereby adjusting the spacing between the two cross bars 22, which is convenient for adapting to the fixation of objects of different lengths, and by adjusting the position of the cross bar 22, the position of the special-shaped object can be adjusted, so that the center of gravity of the special-shaped object is kept consistent with the center of gravity of the drone, ensuring that the special-shaped object always remains balanced during transportation or operation, thereby improving stability and safety.

[0035] Specifically, the support device 3 includes a support leg 31 installed on the fixed beam 21 and a transverse support frame 32 provided at the bottom of the support leg 31 to ensure that the drone remains stable when landing on the platform.

[0036] In addition, the second slide groove 211 runs through the left and right ends of the fixed beam 21, and the number of cross bars 22, clamping blocks 23, and fixing belts 29 can be increased according to actual needs. When increasing, the slide 221 is inserted into and fixed on the fixed beam 21 through the two ends of the second slide groove 211. When transporting more complex or larger special-shaped objects, new cross bars 22, clamping blocks 23, and fixing belts 29 can be added to fix the special-shaped objects in all directions, further improving stability and safety.

[0037] At the same time, the support leg 31 is a round rod structure and is arranged in an inverted "V" shape. The top of the support leg 31 is connected to the fixed beam 21 through a connecting seat 33. The connecting seat 33 is installed at both ends of the top of the fixed beam 21. The connecting seat 33 is provided with a circular hole for rotation and adjustment of the support leg 31. Therefore, when a new slide 221 needs to be added, the support leg 31 can be rotated upward around the connecting seat 33 to facilitate the installation of the slide 221 and the cross bar 22, the clamping block 23, and the fixing belt 29 to the bottom of the fixed beam 21.

[0038] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
