[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] This invention provides, for example Figure 1-7 Shown: Example 1: An unmanned shipborne drone deployment and recovery system, comprising: Hull 1, with a lifting trough at the stern of hull 1; The lifting unit is installed inside the lifting groove; A lifting cage 2 is set inside a lifting groove. The outer wall of the lifting cage 2 is fixedly connected to the lifting part, which is used to control the movement of the lifting cage 2. Steel mesh 3, the outer wall of steel mesh 3 is interwoven with the inner wall of the bottom of the lifting cage 2; Specifically, the lifting unit includes: Multiple guide rails 13 are fixedly connected to the inner walls on both sides of the lifting groove, respectively. Multiple linear motor modules 14 are fixedly connected to the outer walls on both sides of the lifting cage 2, and the output end of the multiple linear motor modules 14 is slidably inserted into the side of the multiple guide rails 13 that are close to each other. It should be noted that multiple guide rails 13 are fixedly connected to the inner walls of both sides of the lifting trough. The sides of the multiple guide rails 13 that are close to each other are slidably connected to the output ends of multiple linear motor modules 14. The multiple linear motor modules 14 are fixedly connected to the outer walls of both sides of the lifting cage 2. The lifting cage 2 is located inside the lifting trough. The bottom inner wall of the lifting cage 2 is interlaced with the outer wall of the steel mesh 3. The surface of the steel mesh 3 is covered with an anti-rust coating. During the amphibious UAV marine recovery operation, the amphibious UAV relies on its onboard GPS positioning module to receive satellite positioning signals in real time, accurately lock the azimuth coordinates and navigation position of the working vessel 1, autonomously plan its flight and navigation route, gradually approach the working waters around the vessel 1, and smoothly land and anchor in the designated recovery waters behind the stern of the vessel 1. At the same time, the vessel 1 simultaneously starts multiple linear motor modules 14. Utilizing the sliding cooperation between the linear motor modules 14 and the matching guide rails 13, the guide rails 13 are linear sliding rail structures, which are used to guide the linear motor modules 14. The sliding platform is limited by multiple degrees of freedom in vertical up / down, horizontal left / right, pitch, yaw, and roll, retaining only the axial linear movement degree of freedom. This allows the linear motor module 14 to slide smoothly only along the length of the guide rail 13. The linear motor module 14 drives the lifting cage 2 to move vertically downward smoothly along the guide rail 13, causing the lifting cage 2 to slowly sink below the sea surface. The lifting cage 2 and the bottom steel mesh 3 are integrated. As the lifting cage 2 sinks, the steel mesh 3 moves synchronously, completely submerging in the water and smoothly reaching the preset underwater recovery position, completing the positioning preparation of the recovery mechanism. After the underwater steel mesh 3 is fully positioned, the amphibious drone, which is moored in the stern area, is guided to slowly move to a position directly above the underwater steel mesh 3 through remote control or autonomous movement control. Then, the linear motor modules 14 are controlled to operate synchronously, driving the lifting cage 2 to rise upward along the guide rail 13 and gradually float to the surface. During the process, the steel mesh 3 is moved upward as a whole, so that the top surface of the steel mesh 3 is stably attached to the bottom of the amphibious drone. With the overall lifting force of the lifting cage 2 and the steel mesh 3, the amphibious drone is completely lifted and lifted off the water surface, leaving the seawater environment. This completes the overall recovery operation of the amphibious drone. Magnetic blocks can be fixedly installed on the bottom of the amphibious drone. When the steel mesh 3 is attached to the bottom of the drone, the magnetic attraction effect is used to achieve rapid attachment and fixation between the amphibious drone and the steel mesh 3. This effectively suppresses displacement caused by rising and falling, swaying of the hull 1 and wind and waves on the sea surface, and prevents the drone from slipping, shaking or even capsizing during the lifting and transportation process. This greatly improves the structural stability and operational safety of the entire process of amphibious drone recovery at sea. Multiple hatch covers 4 are provided on the top of one end of the hull 1 near the lifting channel, and the bottom of the multiple hatch covers 4 are slidably connected to the top of the hull 1. Multiple hatch covers 4 are fixedly installed with movable blocks 15 on one side near the middle of the hull 1. A driving component is provided on the top of one end of the hull 1 near the hatch cover 4. The driving component is used to drive the movable blocks 15 to move. Specifically, the driving components include: Multiple mounting plates 5, one end of which is fixedly connected to the top of the end of the hull 1 near the hatch 4; The threaded rod 6 has two ends that are rotatably inserted into the ends of multiple mounting plates 5 that are close to each other. The threads at both ends of the threaded rod 6 are opposite. The outer walls of the two ends of the threaded rod 6 are threadedly sleeved with the ends of multiple moving blocks 15 that are away from the hatch cover 4. Drive motor 16 is fixedly installed on the top of one end of the hull 1 near the hatch 4, and the output end of drive motor 16 is fixedly connected to one end of threaded rod 6. It should be noted that one end of each of the mounting plates 5 is fixedly connected to the top of the end of the hull 1 near the hatch 4. The ends of the mounting plates 5 that are close to each other are threadedly connected to both ends of the threaded rod 6. The threads at both ends of the threaded rod 6 are opposite. The outer walls at both ends of the threaded rod 6 are respectively threadedly sleeved to one end of each of the moving blocks 15. The ends of the moving blocks 15 that are away from the threaded rod 6 are respectively fixedly connected to one side of each of the hatches 4. The bottom of each hatch 4 is slidably connected to the top of the hull 1. The drive motor 16 is fixedly connected to the top of the end of the hull 1 near the hatch 4. The output of the drive motor 16... The output end is fixedly connected to one end of the threaded rod 6. When recovering the amphibious drone, the drone uses GPS signals to locate itself near the hull 1 and lands behind the stern of the hull 1. Simultaneously, multiple linear motor modules 14 are activated. Through the cooperation of the linear motor modules 14 and the guide rail 13, the lifting cage 2 is submerged in the water. The movement of the lifting cage 2 moves the steel mesh 3, causing the steel mesh 3 to submerge in the water. After the steel mesh 3 is in place, the amphibious drone is moved to the top of the steel mesh 3, and the linear motor module 14 drives the lifting cage 2 to float to the surface. 2. The movement of the steel mesh 3 causes the top of the steel mesh 3 to contact the bottom of the amphibious drone. The amphibious drone is then lifted out of the water using the steel mesh 3 and the lifting cage 2, thus completing the recovery of the amphibious drone. After the drone is recovered, the lifting cage 2 and the steel mesh 3 work together to support the drone and make it parallel to the top of the hull 1. The drive motor 16 is then started, and the output end of the drive motor 16 drives the threaded rod 6 to rotate. The rotation of the threaded rod 6 drives the moving block 15 to move, and the movement of the moving block 15 drives the hatch 4 to move. The hatches 4 move closer together and to the top of the lifting cage 2, providing protection for the recovered drone. At the same time, a wireless charging device can be installed inside the hatch 4 to charge the recovered drone. After the drone is fully charged and the hull 1 moves to the next working area, the output end of the drive motor 16 drives the threaded rod 6 to rotate. The rotation of the threaded rod 6 drives the moving block 15 to move, and the movement of the moving block 15 drives the hatch 4 to move away from each other, thus removing the protection of the drone from the hatch 4, so that the drone can take off for subsequent operations. Example 2: The present invention provides an aerial recovery unit, which is applied to an unmanned shipborne drone deployment and recovery system of Example 1. The aerial recovery unit is located in the middle of the ship hull 1 and is used for aerial drone recovery. Specifically, the aerial recovery unit includes a tethered flight platform 7, support components, and a capture net 8; The moored flight platform 7 is located in the middle of hull 1; The support component is located at the bottom of the moored flight platform 7 and is used to fix the moored flight platform 7 to the hull 1. The outer wall of the capture net 8 is interwoven with the inner wall of the tethered flight platform 7; It should be noted that the support component is located at the bottom of the moored flight platform 7, and the top of the support component is fixedly connected to the bottom of the moored flight platform 7. The support component supports the moored flight platform 7 and fixes it to the middle of the hull 1. The inner wall of the moored flight platform 7 is interlocked with the outer wall of the capture net 8. The capture net 8 is a steel structure with a rust-proof coating. When recovering the UAV in high sea states, the moored flight platform 7 is activated, causing it to take off and hover in the air. The moored flight platform 7 is equipped with a multi-rotor power system, which includes a propeller, a brushless motor, and a flight controller. After being powered on, the rotors rotate at high speed, generating upward aerodynamic lift. When the total lift is greater than the weight of the moored flight platform 7 itself, the drag of the mooring cable, and the weight of the payload, the platform lifts vertically off the ground and gradually climbs to the set altitude. The flight controller adjusts the speed of each rotor in real time so that the total lift generated by the rotors is equal to that of the moored flight platform 7. The weight of the tethered flight platform 7, combined with the vertical tension of the tethered cable 17 and the wind load, balances the vertical forces, thus maintaining a constant altitude. The movement of the tethered flight platform 7 moves the capture net 8, causing it to hover in the air. The UAV, through its built-in visual recognition and positioning perception modules, identifies and locks the position, outline, and docking marks of the aerial tethered flight platform 7 and the capture net 8 in real time. It autonomously corrects its flight path and attitude, slowly approaches the target area, and lands precisely and under control on the top support area of ​​the capture net 8. The capture net 8 supports and captures the UAV. After the UAV is completely placed on the surface of the capture net 8 and fixed to the capture net 8 by magnetic attraction at the bottom, the tethered flight platform 7 is controlled to gradually reduce its flight altitude, maintain a stable overall attitude, overcome the interference caused by sea waves and the swaying of the hull 1, and slowly descend back to the preset placement position on the top of the hull 1. Finally, the fully automatic and safe recovery operation of the UAV at sea under high sea state conditions is completed. Specifically, the support components include: Multiple support frames 11, one end of each of the multiple support frames 11 is fixedly connected to the bottom corner of the tethered flight platform 7; Multiple support blocks 12, the middle part of the top of the multiple support blocks 12 is fixedly connected to the end of the multiple support frames 11 away from the moored flight platform 7, and the bottom of the multiple support blocks 12 is attached to the top of the hull 1; Furthermore, each of the multiple support blocks 12 has an installation groove at the bottom center, and a magnet 19 is fixedly installed in each of the multiple installation grooves. The end of the multiple magnets 19 away from the installation groove is attached to the bottom of the hull 1. It should be noted that one end of each of the multiple support frames 11 is fixedly connected to the bottom corner of the tethered flight platform 7, and the bottom of each of the multiple support frames 11 is fixedly connected to the top center of each of the multiple support blocks 12. Each of the multiple support blocks 12 has an installation groove at its bottom, and the inner wall of each of the multiple installation grooves is fixedly connected to a multiple magnet 19. After the UAV is recovered, the tethered flight platform 7 is lowered onto the top of the hull 1. The movement of the tethered flight platform 7 drives the support frames 11 to move, and the movement of the support frames 11 drives the support blocks 12 to move, so that the support blocks 12 are in contact with the top of the hull 1. The support blocks 12 and the support frames 11 support the tethered flight platform 7. The movement of the support blocks 12 drives the magnets 19 to move, so that the bottom of the magnets 19 is in contact with the top of the hull 1. The magnetic force of the magnets 19 fixes the support blocks 12 to the top of the hull 1, thereby preventing the tethered flight platform 7 from capsizing due to the swaying of the hull 1 and improving stability. Reinforcing rods 9 are fixedly installed at the corners of the inner wall of the tethered flight platform 7. Connecting blocks 10 are fixedly installed at the ends of multiple reinforcing rods 9 that are close to each other. The two sides of the multiple reinforcing rods 9 are interwoven with the capture net 8. A cable 17 is fixedly installed at the bottom center of the connecting block 10. A winch 18 is provided at the bottom of the moored flight platform 7. The winch 18 is fixedly connected to the top of the hull 1. The output end of the winch 18 is wrapped around the end of the cable 17 away from the connecting block 10. It should be noted that one end of each of the multiple reinforcing rods 9 is fixedly connected to the inner corner of the moored flight platform 7, and the ends of the multiple reinforcing rods 9 that are close to each other are fixedly connected to the outer wall of the connecting block 10. The two sides of the multiple reinforcing rods 9 are interlaced with the capture net 8. The reinforcing rods 9 reinforce the moored flight platform 7 and the capture net 8 to prevent deformation of the moored flight platform 7 and the capture net 8 due to the weight of the UAV. The bottom middle of the connecting block 10 is fixedly connected to one end of the cable 17, and the end of the cable 17 away from the connecting block 10 is wound and connected to the output end of the winch 18. The winch 18 is fixedly connected to the top of the hull 1. This allows for the capture of UAVs in high sea states. When the drone is being recovered, the tethered flight platform 7 is activated, causing it to take off and hover in the air. The movement of the tethered flight platform 7 moves the capture net 8, causing it to hover as well. The drone identifies the tethered flight platform 7 and lands on top of the capture net 8. The capture net 8 supports and captures the drone. After the drone attaches to the capture net 8, the winch 18 is activated, retrieving the cable 17 through its output. During descent, the cable 17 provides downward traction. The flight control system of the tethered flight platform 7 actively fine-tunes the total rotor lift to balance the lift relative to its own weight and the cable 17. The traction force and wind disturbance force are dynamically balanced in real time, allowing for slow and controlled unloading and uniform descent to avoid weightlessness, falls, or swaying. Simultaneously, cable 17 maintains appropriate tension at all times, neither slack nor excessively taut, providing horizontal traction constraint to the tethered flight platform 7, counteracting lateral wind forces and horizontal drift, limiting left-right and forward-backward movement, and preventing swaying or spinning during descent. Cable 17 pulls the connecting block 10, which in turn moves the reinforcing rod 9, which in turn moves the tethered flight platform 7. Through the cooperation of cable 17 and winch 18, the tethered flight platform 7 is assisted in landing and avoids... When the untethered flight platform 7 deviates during landing, it is lowered to the top of the hull 1. The movement of the untethered flight platform 7 moves the support frame 11, which in turn moves the support block 12, bringing it into contact with the top of the hull 1. The support block 12 and the support frame 11 support the untethered flight platform 7. The movement of the support block 12 moves the magnet 19, bringing its bottom into contact with the top of the hull 1. The magnetic force of the magnet 19 fixes the support block 12 to the top of the hull 1, thus securing the untethered flight platform 7 and completing the recovery operation of the aerial drone. In this embodiment, the untethered flight platform 7 can also serve as a deployment platform for the drone, facilitating its takeoff.

[0026] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
