DETAILED DESCRIPTION

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] A general-purpose UAV sea-drop cargo hold is made of materials such as stainless steel and engineering plastics. The thickness of the materials is determined according to the UAV airdrop height and speed. Its structural strength meets the requirements of the cargo hold not being deformed or leaking after entering the sea. Figure 1 As shown, it includes a load-bearing body 2, a conformal box 3, a shock-absorbing floating airbag 4 and a traction recovery system 5, wherein the upper part of the load-bearing body is connected to the UAV 1 bracket, and the traction recovery system is installed on the surface of the load-bearing body through the upper sealing plate. The lower part of the load-bearing body is connected to the conformal box and the shock-absorbing floating airbag, and the shock-absorbing floating airbag is connected to the side of the conformal box with waterproof glue.

[0027] like Figure 2 、 Figure 3 As shown, the load-bearing body includes a stainless steel ring 22, a cross-shaped stainless steel tube 21 and a stainless steel column, wherein the cross-shaped stainless steel tube is installed in the center of the stainless steel ring and is welded to the stainless steel ring to provide support for the stainless steel ring. A horizontal threaded hole is provided on the outer diameter of the stainless steel ring for connection to the conformal box. At the same time, the stainless steel ring is used to provide tension to the conformal box mouth. A stainless steel connecting column 24 is welded upward from the center of the cross-shaped stainless steel tube, which is the lifting point of the entire cargo hold. The top of the stainless steel connecting column is a mushroom head for connection to the drone rack; stainless steel columns 23 are welded upward at the left and right ends of the cross-shaped stainless steel tube. The stainless steel columns are used to limit the load-bearing body so that the cargo hold will not shake when the drone is suspended. The upper cover covers the entire stainless steel ring, and a built-in partition in the middle is used to arrange the traction recovery system.

[0028] The load-bearing body also includes the Beidou beacon 25, which is installed on the side of the stainless steel connecting column to provide location information for ships to find cargo holds.

[0029] like Figure 4 and Figure 5 As shown, the conformal box features a large top and a small bottom, primarily made of engineering plastic. This reduces wind resistance during drone flight, provides a first layer of waterproof protection for cargo once it enters the sea, and provides a certain amount of buoyancy. The top edge of the conformal box is designed as a snap-fit ​​design to better mate with the stainless steel ring of the load-bearing structure. Stainless steel bars 31 are embedded longitudinally along the bottom of the conformal box to reduce damage to the box from longitudinal impact forces when the box enters the sea. The stainless steel bars are threaded into threaded holes on the outer diameter of the stainless steel ring of the load-bearing structure. The top edge of the conformal box is also threaded into threaded holes on the outer diameter of the stainless steel ring of the load-bearing structure.

[0030] like Figure 6 As shown, the black outline of the airbag and the blue outline of the conformal case are bonded together with waterproof adhesive. The yellow and blue-black areas are joined together using waterproof adhesive. The shock-absorbing buoy airbag consists of a reservoir, an air valve, an auxiliary airbag, and a float. This design reduces wind resistance in the cargo hold during flight with the drone, provides primary shock absorption when the cargo hold enters the sea, provides sufficient buoyancy, and ejects the foam drone from the traction recovery system when the cargo hold enters the sea. The reservoir features a streamlined, pointed tip and is bonded to the conformal case. The reservoir is mounted at the bottom of the shock-absorbing buoy airbag, the float is mounted above it, and the auxiliary airbag is mounted in the traction recovery system. An air duct is located within the float, connecting the auxiliary airbag at its upper end and the reservoir at its lower end. A valve is located near the reservoir at the lower end of the airduct. Normally, the auxiliary airbag and float are deflated. When the cargo hold enters water, the air in the airbag pushes open the valve and enters the auxiliary airbag and float. The airbag's shock absorption effect can be adjusted by adjusting the valve flow rate. The auxiliary airbag is placed on the underside of the drone cabin in the traction recovery system. Once inflated, it ejects the drone from the cargo hold, allowing it to float on the sea surface. The float is designed in a butterfly shape, with the buoyant airbag in the middle and adhesive waterproof fabric on both wings. The buoyant airbag is connected to the stainless steel ring with a rolled belt. The adhesive waterproof fabric on both wings is adhered to the upper cover plate and conformal box of the load-bearing body, respectively. Upon entering water, the buoyant airbag inflates, providing both buoyancy and sealing for the cargo hold.

[0031] like Figure 7 and Figure 8As shown, the blue section represents the load-bearing stainless steel ring and cross-shaped stainless steel frame, while the yellow and green sections represent the interlayer areas. The green section is the drone area, with a secondary airbag located underneath and the upper layer encapsulated with fragile materials. The yellow section is the cable area, with the upper layer encapsulated with ordinary plastic. The traction and recovery system includes a foam drone 53, a towing cable 52, a guide cable 51, and a clamping ring, providing rapid salvage and recovery capabilities for the cargo hold. A secondary airbag is installed beneath the foam drone, one end of the towing cable is connected to the foam drone, and the other end of the towing cable is connected to the guide cable, which is connected to a stainless steel connecting column, and the clamping ring is mounted on the guide cable. The foam drone automatically pops out and floats to the sea surface the moment the cargo hold enters water. It is manually controlled to take off and land on the ship's deck. The towing cable connects the drone and the guide cable. It is approximately 50 meters long and made of lightweight and tough material. Once the drone lands on the deck, the guide cable can be pulled onto the deck via the towing cable. The guide cable, approximately 30 meters long and made of high-polymer nylon, connects the towing cable to the middle stainless steel column of the load-bearing structure. Deck crews use the guide cable to pull the cargo hold to the ship's side, untie the guide cable from the towing cable, and thread the guide cable through a collar (connected to a crane hook). The collar, using gravity, slides down the guide cable until it latches onto the mushroom head of the stainless steel column. The crane then hoists the cargo hold onto the deck for recovery.

[0032] The clamping ring is suspended by a crane. Once the foam drone is aboard, deck personnel use the drone's towing cable (which is thin and light, minimizing impact on the drone) to retrieve one end of the guide cable (which is slightly heavier and difficult for the drone to tow, so force is transmitted through the towing cable). The deck personnel thread the guide cable through the clamping ring, which then precisely latches onto the mushroom head in the cargo hold along the guide cable. The clamping ring and mushroom head are similar in function to a buckle, and the mushroom head has a spring-loaded buckle, allowing the clamping ring to latch onto the buckle through its own weight.

[0033] like Figure 9 As shown, the working process of the utility model is:

[0034] Step 1: Attach the transport drone to the cargo hold.

[0035] Step 2: The transport drone flies over the target sea area and drops the cargo hold into the sea at low altitude. During the flight, only the airbag is filled with high-pressure gas.

[0036] Step 3: The moment the cargo hold enters the sea, the airbag is impacted, and the air rushes open the valve and enters the auxiliary airbag and float. The auxiliary airbag ejects the built-in foam drone out of the cargo hold.

[0037] This step is implemented as follows: After the cargo hold falls into the water, the powerful impact causes the gas in the lower airbag to break through the valve, partially entering the upper airbag (connected to the load-bearing body) and partially entering the auxiliary airbag under the drone. This forces the drone to break through the fragile surface material and eject from the drone compartment, preventing it from becoming entangled in the cargo hold. Simultaneously, due to the water pressure, most of the gas is pressed against the upper airbag while the cargo hold is submerged, ensuring that the three cargo hold columns remain facing upward.

[0038] Step 4: Deck crew remotely controls the foam drone to land on the deck.

[0039] Step 5: Use the towing cable to pull one end of the guide cable onto the deck and connect the clamp ring to the crane hook.

[0040] Step 6: Use the guide cable to pull the cargo hold to the side of the ship.

[0041] Step 7: Untie the guide cable from the traction cable and pass one end of the guide cable through the clamp.

[0042] Step 8: The clamping ring uses gravity to slide down along the guide cable until it buckles onto the mushroom head of the stainless steel column.

[0043] Step 9: Use a crane to lift the cargo hold to the deck to recover the cargo hold.

[0044] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
