The parachute 100's parachute line is connected to a program belt 170 for opening the carrying container 200 to release the parachute 100, the life-saving equipment bags 110, and the lifeboat 120.

[0033] The carrying container 200 includes a carrying fabric 210 that can be rolled up and connected into a cylindrical shape along the length direction, two main parachute connecting belts 220 connected to the carrying fabric 210, and eight packaging blades 230 respectively connected to both sides of the carrying fabric 210. The main parachute connecting belt 220 extends along the width direction of the carrying fabric 210 and is provided with a connecting top buckle 240 at one end for connecting the parachute 100 rope. Two handles 221 are provided on the main parachute connecting belt 220. The two ends of the carrying fabric 210 are respectively connected to end reinforcement belts 270 extending along its width direction. The two end reinforcement belts 270 are respectively connected to packaging reinforcement belts 280. Side packaging buckles 250 and side packaging rings 260 are respectively provided. Fourteen side packaging buckles 250 extending along the width direction of the carrying fabric 210 are provided on one packaging reinforcement belt 280. The other packaging reinforcement belt 280 is connected to a side packaging buckle 250 corresponding to the side packaging buckle. The side packaging ring 260 on the packaging buckle 250, each side packaging buckle 250 can be sleeved on the next adjacent side packaging buckle 250, the program belt 170 is connected with the side packaging pin 190 and the bottom packaging pin 320, and the last side packaging buckle 250 passes through the corresponding side packaging ring 260 and the previous adjacent side packaging buckle 250 and is sleeved on the side packaging pin 190; the two ends of the supporting fabric 210 are respectively connected with a fixed tether 290 and a tether lock 300 for detachably connecting the fixed tether 290, each packaging blade 230 is provided with a blade gasket 231, and a packaging blade 230 on one side of the supporting fabric 210 is connected with a blade packaging buckle 310 for passing through each blade gasket 231 on the corresponding side, and the bottom packaging pin 320 is used to pass through the blade packaging buckle 310 of each blade gasket 231 on the other side of the supporting fabric 210.

[0034] Each lifesaving equipment bag 110 is connected to a loop 160 via a connecting belt 130. The rope loop 140 of the parachute 100 is connected to a fixing pin 150 that can be inserted into or removed from each loop 160. The supporting fabric 210 is provided with an adapter ring 330 respectively connected to each connecting belt 130. The parachute 100 is also connected to a spring-guided parachute 340. The lifeboat 120 is connected to the supporting fabric 210 via a floating cable 350. The lifeboat 120 is equipped with an activation pin 180 that inflates it when pulled out. The adapter ring 330 is connected to the activation pin 180 via a pull rope. The lifesaving equipment bag 110 is made of polyurethane tape.

[0035] The working principle of the airdrop structure of the combined rescue items provided in the embodiment of the present application is as follows: before airdrop, the parachute 100, the two life-saving equipment bags 110 and the lifeboat 120 are placed on the carrier fabric 210, the start pin 180 of the lifeboat 120 is connected to the program belt 170, the two life-saving equipment bags 110 are connected by the ring 160 connected by the connecting belt 130 and are placed on the fixed pin 150 on the rope ring 140 of the parachute 100, and then the two ends of the carrier fabric 210 are rolled into a cylindrical shape along the length direction. The side of the suture is sewn together with a suture thread, and each side of the other side of the carrier fabric 210 is passed through a corresponding side closure buckle 250. The ring 260 is then put on the next adjacent side packaging buckle 250, and the last side packaging buckle 250 is passed through the corresponding side packaging ring 260 and the previous adjacent side packaging buckle 250 and then put on the side packaging pin 190 on the program belt 170. Then, the four packaging leaves 230 at the bottom of the supporting fabric 210 are bent, closed and rolled into the cylindrical bottom of the supporting fabric 210. The bottom packaging pin 320 on the program belt 170 is passed through the leaf packaging buckles 310 on the four bottom packaging leaves 230 to fix them, and the leaf packaging buckles 310 at the top of the supporting fabric 210 are respectively passed through the four leaf gaskets 231 at the top to fix them.

[0036] When the airdrop structure of the combined rescue item is airdropped, the parachute 100 is connected to the parachute opening rope 360 on the aircraft and then airdropped. The parachute opening rope 360 pulls the parachute 100 out of the parachute bag and the top of the supporting fabric 210 to open it. At this time, the rope ring 140 of the parachute 100 pulls the connected fixing pins 150 out of each ring 160, so that each ring 160 and the connected life-saving item bag 110 are separated from each other. At the same time, when the parachute 100 is opened, it drives the program belt 170 to move so that the side package latch 190 and the bottom package latch 320 are respectively separated from the last side package buckle 250 and the blade package buckle 310 of each blade washer 231 at the bottom, so that the impact force of the airdrop impacts each side package buckle 250 to separate from the corresponding side. The sealing collar 260 and the previous adjacent side sealing buckle 250 cause the side of the carrying container 200 to open, and the blade washers 231 at the bottom to open, allowing the two lifesaving supply bags 110 and the lifeboat 120 contained in the carrying container 200 to fall down, so that the two lifesaving supply bags 110 are suspended below the carrying container 200 via the collars 160 connected by the connecting belts 130, and the program belt 170 pulls out the activation pins 180 on the lifeboat 120, so that the lifeboat 120 is inflated and then suspended below the two lifesaving supply bags 110 via the floating cable 350. Therefore, during the airdrop process, the release and inflation of the lifeboat 120 and the release of the lifesaving supply bags 110 are separated, making it convenient for the recipient to receive the airdropped lifeboat 120 and lifesaving supply bags 110 for use.

[0037] The life-saving equipment bag 110, made of polyurethane tape, floats in water, making it easy for personnel to retrieve and adjust the rescue materials according to the actual rescue situation. The carrier fabric 210 is equipped with adapter rings 330 that connect to each connecting strap 130. This ensures that the two life-saving equipment bags 110 are stably connected and suspended below the carrier fabric 210 after being released and separated from the carrier container 200 for reception by personnel. The parachute 100 is also connected to a spring-guided parachute 340, which can quickly straighten and fully expand the parachute 100 during deployment, protecting the parachute 100 from wind and flow fields and ensuring smooth inflation and deployment.

[0038] The main parachute connecting belt 220 is provided with a connecting top buckle 240 for connecting the parachute 100 rope, which can ensure that the parachute 100 is stably opened during airdrop by connecting the top buckle 240. The handle 221 provided on the main parachute connecting belt 220 can be used for convenient transportation and fixing on the aircraft before airdrop; the packaging blades 230 are used to close the top and bottom of the supporting fabric 210 rolled into a cylindrical shape to package the parachute and airdropped supplies; the two ends of the supporting fabric 210 are respectively connected to a fixed mooring belt 290 and a mooring belt lock 300 for detachably connecting the fixed mooring belt 290. The fixed mooring belt 290 and the mooring belt lock 300 can be used to tie and tie external rescue items, and the connection length can be adjusted according to the connection between the fixed mooring belt 290 and the mooring belt lock 300 as needed.

[0039] The two ends of the carrying fabric 210 are respectively connected to end reinforcement belts 270, which can improve the structural strength and rigidity of the connection between the two ends of the carrying fabric 210, and improve the carrying capacity of the airdrop structure; each end reinforcement belt 270 is connected to a packaging reinforcement belt 280, which can ensure the strength of the side packaging buckle 250 and the side packaging ring 260, thereby ensuring the strength of the airdrop structure; the packaging blade 230 is connected to a blade packaging buckle 310 for passing through each blade gasket 231 on the corresponding side, which can close and lock the top of the carrying container 200 to accommodate the parachute 100 and the life-saving equipment bag 110.

[0040] An embodiment of the present application also provides an airdrop system, which includes the above-mentioned airdrop structure for the combined rescue items.

[0041] The embodiments described above are part of the embodiments of the present application, rather than all of the embodiments. The detailed description of the embodiments of the present application is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
