Description

Technical Field

[0001] This invention relates to the field of underwater salvage equipment technology, specifically to an aircraft salvage and anchoring device carried by a remotely operated vehicle (ROV). Background Technology

[0002] In salvage operations of crashed aircraft, the formation of anchor points is one of the key aspects of the entire process. An anchor point is a stable fulcrum selected and fixed on the sunken aircraft wreckage, used to connect salvage equipment (such as salvage cables) to the mother ship or salvage platform. The method of forming anchor points directly affects the efficiency, safety, and success rate of the salvage operation.

[0003] Currently, the initial underwater salvage operations are mainly carried out by divers. In shallow water, divers can be relied upon entirely to generate underwater anchoring points. In depths of 60-180m, ROVs can be used to assist divers. However, in deep-sea salvage operations, the role of divers is very limited, and ROVs are mainly used for underwater operations.

[0004] Currently, there is a lack of experience in China for underwater cable anchoring operations using ROVs, and there are no suitable perforation devices among the special tools for ROV manipulators used in deep working conditions such as 1000m to 6000m. Utility Model Content

[0005] This invention discloses an aircraft retrieval anchoring device that can be matched with holes on the aircraft (such as holes on the wings) to quickly connect retrieval equipment.

[0006] To achieve the above objectives, the technical solution of this invention is as follows: An aircraft salvage and anchoring device includes a sleeve, a guide mechanism, a combined conical connector, and a connecting mechanism. The top of the sleeve is provided with the connecting mechanism. The combined conical connector is connected to the sleeve through the guide mechanism. The combined conical connector includes several connecting blocks. The connecting blocks move inward along the guide mechanism to form a conical body, and move outward along the guide mechanism to form several disassembled connecting blocks. The disassembled connecting blocks are used to connect with existing holes or processed holes on the aircraft to be salvaged. The maximum outer diameter of the conical body is smaller than the inner diameter of the hole, and the bottom ends of each disassembled connecting block mate with the hole.

[0009] Preferably, the bottom end of the sleeve is closed and has multiple radially arranged guide grooves around the axis. The guide grooves are evenly distributed. The force transmission rod passes through the guide grooves and slides in cooperation with them. The guide grooves divide the bottom end of the sleeve into a first connecting area in the middle, a second connecting area on the inner edge of the sleeve, and a third connecting area between the first and second connecting areas.

[0010] Preferably, the guiding mechanism includes a fixed rod fixedly connected between the center of the top end of the sleeve and the first connecting area.

[0018] This novel aircraft salvage and anchoring device, such as... Figure 1-5 As shown, the device includes a sleeve 1, a guide mechanism, a combined conical connector, and a connecting mechanism. The top of the sleeve 1 is provided with a connecting mechanism. The combined conical connector is connected to the sleeve 1 through the guide mechanism. The combined conical connector includes several connecting blocks 6. The connecting blocks 6 move inward along the guide mechanism to form a conical body. Due to the reduced size, it can pass through existing holes on the aircraft or holes processed in conjunction with this device. It also moves outward along the guide mechanism to form several disassembled connecting blocks. After disassembly, each connecting block 6 is stuck in the hole. The disassembled connecting blocks 6 are used to connect with existing holes or processed holes on the aircraft to be salvaged. The maximum outer diameter of the conical body is smaller than the inner diameter of the hole. The bottom ends of the disassembled connecting blocks cooperate with the holes, so they can be inserted into the holes simultaneously.

[0019] In this embodiment, as Figure 1-5 As shown, the top of the sleeve 1 is closed and connected to the connecting mechanism at the central axis. The connecting mechanism includes a connecting rod 2 arranged vertically for the robot ROV to hold. The bottom end of the connecting rod 2 is fixedly connected to the top of the sleeve 1. A connecting ring 3 is fixedly connected to the top of the connecting rod 2 for connecting to salvage equipment, such as tying a cable.

[0020] In this embodiment, as Figure 1 , 2As shown, the connecting block 6 has a right-angled triangle cross-section, with the hypotenuse 7 facing outwards and downwards. The plane containing the hypotenuse 7 is part of the outer surface of the cone. A support column 5 is vertically connected to the top of the connecting block 6, and a force transmission rod 4 is connected to the top of the support column 5. The connecting block 6 can be part of a conical structure or a regular polygonal cone. After multiple connecting blocks contract inwards to form a cone, they can pass through the holes in the aircraft. After spreading out, they can hook onto the edge of the hole and connect to the aircraft through the plane containing the right-angled side of the top of the connecting block.

[0021] In this embodiment, as Figure 5 As shown, the bottom end of the sleeve 1 is closed and has multiple radially arranged guide grooves 18 around its axis. The guide grooves 18 are evenly distributed. The force transmission rod 4 passes through the guide grooves 18 and slides in cooperation with them. The guide grooves 18 divide the bottom end of the sleeve 1 into a first connecting area 15 located in the middle, a second connecting area 16 located on the inner edge of the sleeve 1, and a third connecting area 17 connecting the first connecting area 15 and the second connecting area 16. This arrangement can enhance the structural strength of the sleeve. The guide grooves allow the force transmission rod to move radially along the sleeve, constraining the movement trajectory of the force transmission rod and keeping the device stable during use.

[0022] In this embodiment, as Figure 2 As shown, the guiding mechanism includes a fixed rod 9 fixedly connected between the center of the top end of the sleeve 1 and the first connecting area 15. The fixed rod 9 is a regular polygonal prism structure. Each side of the fixed rod 9 is connected to a guide rail structure 10 between itself and the inner surface of the sleeve 1. The guide rail structure 10 is inclined to the outside and downward. The top end of the force transmission rod 4 is provided with a slider 11, and the slider 11 is slidably connected to the guide rail structure 10.

[0023] In this embodiment, as Figure 2 , 3 As shown, the slider 11 slides in conjunction with the inner cavity of the guide rail structure 10. The bottom of the inner cavity of the guide rail structure 10 is provided with a strip-shaped through groove (not marked in the figure) for the force transmission rod 4 to move along the guide rail structure 10. The upper part of the inner cavity of the guide rail structure 10 is fixedly provided with a mounting plate (not marked in the figure), and a return spring 12 is connected between the slider 11 and the mounting plate.

[0024] In this embodiment, as Figure 2 , 4 As shown, the guiding mechanism also includes a guide rod 13, which is arranged parallel to the guide rail structure 10 and located below the guide rail structure 10. The two ends of the guide rod 13 are fixedly connected to the outer surface of the fixed rod 9 and the inner wall of the sleeve 1, respectively. The force transmission rod 4 is provided with a sliding hole 14 for the guide rod 13 to pass through, and the guide rod 13 slides in conjunction with the sliding hole 14.

[0025] The working principle of this new type: The underwater robot grips connecting rod 2 and inserts the bottom ends of the separated connecting blocks into holes on the aircraft wing. As the holes compress the connecting blocks, they retract inward under the guidance of a guide mechanism until they are fully inserted into the holes. At this point, under the action of a return spring, the connecting blocks re-open, and the flat surface at the top of the connecting blocks mates with the edge of the holes to prevent the connecting blocks from being pulled out. The connecting ring is used to connect with salvage equipment, such as connecting cables, thus completing the anchoring and fixation between the salvage equipment and the aircraft.
