An insertion tube 9 is installed at the bottom of the air intake assembly 8, and a connecting airbag 10 is fixedly connected to the bottom of the insertion tube 9. Below the connecting airbag 10, there is a mounting block 11. A slot 12 is opened at the top of the mounting block 11, and an airbag groove 13 communicating with the slot 12 is opened inside the mounting block 11. A storage cover 14 is fixedly connected to the bottom of the mounting block 11, and a storage cylinder 15 is installed at the bottom of the storage cover 14. The insertion tube 9 is inserted into the inside of the slot 12, and the connecting airbag 1... 0 is located inside the airbag groove 13, and the outer side of the connecting airbag 10 is tightly fitted to the inner side of the airbag groove 13. Multiple support columns 16 are fixedly connected to the bottom end of the placement plate 3. A circular plate 17 is fixedly connected to the bottom end of the support column 16.

A connecting pipe 20 that is connected to and penetrates the compression airbag 19 and the side plate 18 is fixedly connected to the side of the compression airbag 19 near the side plate 18. The outer side of the compression airbag 19 is tightly fitted to the outer side of the mounting block 11. When installing the storage cylinder 15, place the mounting block 11 at the bottom of the circular plate 17 so that the connecting airbag 10 is inserted into the inner side of the airbag groove 13. Start the air pump 4 to allow air to enter the inner side of the connecting airbag 10 and the pressing airbag 19. The outer side of the connecting airbag 10 and the inner side of the airbag groove 13 are tightly fitted to fix the mounting block 11. The outer side of the pressing airbag 19 and the outer side of the mounting block 11 are tightly fitted to make the storage cylinder 15 more stable and prevent the storage cylinder 15 from shaking during the flight of the UAV body 1, which would affect the flight of the UAV body 1.

[0028] The air intake assembly 8 includes an air intake cylinder 81 fixedly connected inside the storage plate 3 and the circular plate 17 and penetrating through the storage plate 3 and the circular plate 17. A connecting frame 82 is fixedly connected to the inner side of the air intake cylinder 81. A vertically arranged limiting rod 83 is slidably connected to the inner side of the connecting frame 82. A sealing ball 84 is fixedly connected to the top of the limiting rod 83. A return spring 85 located outside the limiting rod 83 is fixedly connected between the sealing ball 84 and the connecting frame 82. The end of the connecting tube 20 away from the compression airbag 19 is fixedly connected to the outside of the air intake cylinder 81 and communicates with the air intake cylinder 81. The bottom end of the air intake cylinder 81 is fixedly connected to the top end of the insertion tube 9 and to the insertion tube 9. The tube 9 is through, and the outer side of the sealing ball 84 is tightly fitted with the top of the inner side of the air inlet cylinder 81. The sealing ball 84 and the electric push rod 7 are vertically aligned. When the air pump 4 is started, the sealing ball 84 moves and causes the return spring 85 to be compressed. At this time, air can enter the inner side of the connecting airbag 10 and the compression airbag 19 through the insertion tube 9 and the connecting tube 20 respectively. When the air pump 4 is turned off, the return spring 85 returns to its original position and causes the outer side of the sealing ball 84 to be tightly fitted with the top of the inner side of the air inlet cylinder 81. The design of the air intake assembly 8 can ensure the airtightness of the connecting airbag 10 and the compression airbag 19 and prevent air leakage that could cause the storage cylinder 15 to fall off.

[0029] Workflow: Before use, power on the device and connect it to an external wireless control device. When it is necessary to install rescue supplies inside the legs 2 on the drone body 1, first place the rescue supplies inside the storage tube 15 and install the storage tube 15 at the bottom of the storage cover 14. Place the mounting block 11 at the top of the storage cover 14 at the bottom of the circular plate 17 below the support column 16, so that the connecting airbag 10 is inserted into the airbag groove 13 and the insertion tube 9 is inserted into the slot 12. Then start the air pump 4 at the top of the storage plate 3. 4. Outside air is introduced into the inside of the connecting cylinder 6 through the air tube 5. The air inside the connecting cylinder 6 pushes open the sealing ball 84 inside the air inlet cylinder 81. The movement of the sealing ball 84 causes the limiting rod 83 to slide inside the connecting frame 82, and the return spring 85 is compressed. At this time, the air can enter the inside of the connecting airbag 10 and the compression airbag 19 through the insertion tube 9 and the connecting tube 20 inside the side plate 18, respectively. The connecting airbag 10 and the compression airbag 19 slowly inflate. The outer side of the connecting airbag 10 fits tightly against the inner side of the airbag groove 13, which can provide pressure relief. The mounting block 11 is used to fix the device in place. The outer side of the compression airbag 19 is tightly fitted to the outer side of the mounting block 11, which makes the storage tube 15 more stable and prevents the storage tube 15 from shaking and affecting the flight of the drone body 1 during flight. After the connecting airbag 10 and the compression airbag 19 are filled with gas, the air pump 4 is turned off. At this time, the return spring 85 returns to its original position and drives the limit rod 83 to slide inside the connecting frame 82 until the outer side of the sealing ball 84 is tightly fitted to the top of the inner side of the air inlet 81. The design of the air intake component 8 can ensure the airtightness of the connecting airbag 10 and the compression airbag 19 and prevent air leakage that could cause the storage tube 15 to fall off. After installation, the operator can control the drone body 1 to take off. When the drone body 1 reaches the appropriate position and the air pump 4 and the electric push rod 7 are started, the output shaft of the electric push rod 7 extends and drives the sealing ball 84 to move. At this time, the air in the connecting airbag 10 and the compression airbag 19 is discharged through the air intake component 8 and the air pump 4. The storage tube 15 is detached from the drone body 1 and falls freely to the ground, thus completing the throwing of rescue supplies.
