Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0022] Example 1: Reference Figures 1-5 This is the first embodiment of the present utility model. This embodiment provides a heavy-duty multi-rotor drone for material transportation, including a drone body 1, a mounting plate 2 fixed to the bottom of the drone body 1, a fixing frame 3 provided below the mounting plate 2, and a connecting component 4 for installing the fixing frame 3 provided at the bottom of the mounting plate 2.

[0023] The UAV body 1, as the main body of the entire transportation equipment, can provide flight power, control flight attitude, and carry other components to realize the function of aerial transportation of materials. The mounting plate 2 is set to provide the mounting base for the fixed frame 3, connecting component 4 and limiting frame 7 below. The fixed frame 3 serves as the mounting carrier for the clamping arm 5, drive component 6 and protective shell 10, and is used to integrate the various components together to form a relatively independent functional module, which is convenient for installation and maintenance. The connecting component 4 is set to install and disassemble the fixed frame 3 through its internal structure.

[0024] The bottom of the fixed frame 3 is rotatably connected to two sets of clamping arms 5 with a left-right symmetrical design. The inside of the fixed frame 3 is provided with a drive assembly 6 for driving the clamping arms 5. The bottom of the mounting plate 2 is provided with two sets of limiting frames 7. The inner wall of the limiting frame 7 is slidably connected to two sets of movable blocks 8. The bottom of the movable blocks 8 is equipped with a lifting ring 9.

[0025] The clamping arm 5 is designed to open and close via the drive assembly 6, and is used to clamp and secure the materials to be transported, ensuring that the materials will not fall during flight. The limiting frame 7 is designed to provide a sliding track and mounting base for the movable block 8. It can also be installed and secured by itself, as well as restrict and adjust the position of the movable block 8, by cooperating with the mounting bolt 17 and fixing bolt 20. The movable block 8 can slide along the limiting rod 18 within the limiting frame 7 to adjust the position of the lifting ring 9 to adapt to the suspension requirements of materials of different shapes and sizes. The lifting ring 9 is designed to suspend the materials to be transported. By adjusting the position of the movable block 8, the position of the lifting ring 9 can be changed, thereby better securing the materials.

[0026] The connecting assembly 4 includes two sets of plug tubes 41 fixed to the bottom of the mounting plate 2, and two sets of plug blocks 42 fixed to the top of the fixing frame 3, with the outer side of the plug block 42 plugged into the inner wall of the plug tube 41.

[0027] The plug-in tube 41 and the plug-in block 42 are used together to provide a plug-in structure for the connection between the fixing frame 3 and the mounting plate 2, so as to realize the initial positioning and connection between the fixing frame 3 and the mounting plate 2, and facilitate the installation and disassembly of the fixing frame 3.

[0028] Example 2: This is the second embodiment of the present invention, which is based on the previous embodiment.

[0029] Specifically, the drive assembly 6 includes a motor 61 mounted on the bottom of the mounting frame 3, a transmission component 62 is provided inside the mounting frame 3, and the output end of the motor 61 is fixedly connected to the shaft of one of the gears in the transmission component 62.

[0030] The motor 61 serves as a power source, providing rotational power to the transmission component 62, which in turn drives the clamping arm 5 to move. The transmission component 62 transmits the rotational power of the motor 61 to the clamping arm 5, enabling the clamping arm 5 to open and close in a predetermined manner, thereby clamping and releasing materials. It should be noted that the transmission component 62 consists of multiple sets of gears designed symmetrically on both sides, with each set of gears meshing with the others. Additionally, two gears in the transmission component 62 are fixedly connected to the top of the clamping arm 5 via a rotating shaft. In use, the motor 61 is first started, and the motor 61 drives the multiple sets of gears to rotate. Through the transmission of the symmetrically designed gears, the two sets of clamping arms 5 can clamp and fix the materials to be transported.

[0031] Specifically, a protective shell 10 for protecting the motor 61 is fixed to the bottom of the mounting bracket 3. The inner wall of the protective shell 10 is provided with a heat dissipation vent 11, and a filter screen is fixed to the inner wall of the heat dissipation vent 11.

[0032] The protective shell 10 is designed to protect the motor 61 from damage caused by collisions, dust, and rain during flight, thus extending the service life of the motor 61. The heat dissipation vent 11 is designed to dissipate heat from the motor 61 during operation, preventing damage due to overheating and ensuring the normal operation of the motor 61. The filter screen on its inner wall prevents dust and debris from entering the protective shell 10 through the heat dissipation vent 11 and contaminating the motor 61 and other components, ensuring a clean working environment for the motor 61.

[0033] Specifically, the inner wall of the plug-in block 42 is provided with a reserved groove 12 with a left and right symmetrical design. A spring 13 is fixed to the inner wall of the reserved groove 12. A snap-fit ​​block 14 is fixed to one end of the spring 13. Both sides of the plug-in tube 41 are provided with snap-fit ​​grooves 15, and the outer side of the snap-fit ​​block 14 snaps into the inner wall of the snap-fit ​​groove 15.

[0034] The reserved slot 12 is provided to provide installation space for the spring 13 and the snap-fit ​​block 14. The spring 13 utilizes its elastic properties to allow the snap-fit ​​block 14 to extend and retract when subjected to external force, thereby achieving snap-fit ​​and separation with the slot 15, enhancing the stability and reliability of the connection between the fixing frame 3 and the mounting plate 2. The snap-fit ​​block 14 can be snapped into the slot 15 by the action of the spring 13, preventing the plug-in block 42 from falling out of the plug-in cylinder 41.

[0035] Example 3: This is the third embodiment of the present invention, which is based on the first two embodiments.

[0036] Specifically, the inner wall of the mounting plate 2 is provided with a limiting groove 16, the top of the limiting bracket 7 is threaded with a mounting bolt 17, and the outer side of the mounting bolt 17 is slidably connected to the inner wall of the limiting groove 16.

[0037] The limiting groove 16 is provided to limit and guide the installation position of the limiting frame 7, so that the limiting frame 7 can move on the mounting plate 2. The mounting bolt 17 is provided to fix the limiting frame 7 on the mounting plate 2. At the same time, the installation position of the limiting frame 7 can be adjusted by sliding within the limiting groove 16.

[0038] Specifically, the inner wall of the limiting frame 7 is fixed with a horizontally arranged limiting rod 18, and the inner wall of the movable block 8 is slidably connected to the outer side of the limiting rod 18.

[0039] The limit rod 18 is designed to guide the sliding of the movable block 8, prevent the movable block 8 from deviating during the sliding process, and ensure the stability of the sliding of the movable block 8.

[0040] Specifically, two sets of fixing blocks 19 are fixed to the top of the movable block 8. The inner wall of the fixing block 19 is threaded with fixing bolts 20. Threaded holes 21 are opened on both sides of the limit frame 7, and the outer side of the fixing bolts 20 is threaded to the inner wall of the threaded holes 21.

[0041] The fixed block 19 is used to fix the movable block 8 on the limit frame 7 to prevent the movable block 8 from sliding during transportation and to ensure the stability of the suspension of materials. The fixing bolt 20 can firmly fix the movable block 8 on the limit frame 7 by cooperating with the threaded hole 21. The multiple sets of threaded holes 21 are used to provide different installation positions for the fixing bolt 20.

[0042] Working principle: When using this heavy-duty multi-rotor UAV for transporting the materials, firstly, align the plug-in block 42 on the top of the mounting frame 3 with the plug-in cylinder 41 at the bottom of the mounting plate 2 and insert it. During the insertion process, the locking block 14 is squeezed by the inner wall of the plug-in cylinder 41, and the compression spring 13 retracts into the reserved groove 12. After insertion, the locking block 14 is locked into the slot 15 under the elastic force of the spring 13, realizing a stable connection between the mounting frame 3 and the mounting plate 2. Next, adjust the position of the limiting frame 7 according to the shape and size of the materials, loosen the mounting bolt 17 to allow it to slide in the limiting groove 16, and tighten the mounting bolt 17 to fix the limiting frame 7 after determining the position. Then, push the movable block 8 to slide along the limiting rod 18, driving the bottom lifting ring 9 to move to the appropriate position. Finally, screw the fixing bolt 20 into the fixing block 19 and screw it into the corresponding threaded hole 21 to fix it. For movable block 8, if transporting materials that need to be clamped, start the bottom motor 61 of the fixed frame 3. The motor 61 drives the gear in the transmission component 62 to rotate. Since the transmission component 62 is composed of multiple sets of gears that are symmetrical and mesh with each other, and two gears are connected to the top of the clamping arm 5 through a rotating shaft, it can drive the two sets of clamping arms 5 to open and close, thereby clamping and fixing the materials. If transporting materials that can be suspended, directly hang the materials on the hanging ring 9. After the materials are fixed, the UAV body 1 provides flight power and controls the flight attitude, taking off with the materials for transport. During the flight, the protective shell 10 protects the motor 61 from collisions, dust and rain damage. The heat dissipation vent 11 and the filter screen ensure heat dissipation of the motor 61 and a clean working environment. After reaching the destination, control the motor 61 to reverse or release the hanging ring 9 to release the materials and complete the transport task.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
