[0018] II. Control Method for Rapid Deployment and Retraction Device of Aircraft

[0019] Based on the same inventive concept, the present invention also provides a control method for the rapid deployment and retraction device for small aircraft as described above, specifically including the following steps:

[0020] S1, determine whether the current task is for the vehicle to receive a task or for the vehicle to deploy a task. If the task is for the vehicle to receive a task, proceed to step S11; if the task is for the vehicle to deploy a task, proceed to step S21.

[0021] S11. When a small vehicle enters a preset range at the stern of a ship, staff monitor the position of the small vehicle in real time using a camera recognition device.

[0022] S12, when the small vehicle reaches the designated position in the groove at the stern of the ship, control the two claw hook electromagnets to generate repulsive force, so that the two claw hooks of the claw device open, and then control the pulley group to lower the entire claw device into the gripping slot of the upper support of the small vehicle.

[0023] S13 controls the two claw electromagnets to generate attraction, causing the two claws of the claw device to close and grab the upper support of the small aircraft. At the same time, the connecting column electromagnet is activated to attract the magnetic block installed on the top of the upper support, making the grabbing process more stable and reliable.

[0024] S14, by controlling the pulley block, the hook device is raised together with the small vehicle to the preset retraction height, and the small vehicle is put into the cabin for maintenance through the ship's stern transmission device, so as to achieve the rapid recovery of the small vehicle.

[0025] S21, when the hook device is lowered to a preset range above the water surface by controlling the pulley block to bring the small vehicle down to the preset range above the water surface, the staff monitors the height of the small vehicle in real time through the camera recognition device.

[0026] S22, when the small vehicle descends to contact the water surface, the two claw hook electromagnets are controlled to generate a repulsive force, causing the two claw hooks of the claw device to open, and at the same time the connecting column electromagnet is closed, so that the upper support of the small vehicle is separated from the claw device, so as to realize the rapid deployment of the small vehicle.

[0027] S23, by controlling the pulley block, the entire hook and claw device is raised to the starting position at the crossbeam.

[0028] Furthermore, in step S12, after the small vehicle reaches the designated position in the groove at the stern of the ship, the speed of the small vehicle is controlled by the speed adjustment module to match the speed of the ship.

[0029] Compared with the prior art, the present invention has the following main advantages:

[0030] 1. This invention, through the cooperation of a hook and claw device, a camera recognition device, a pulley block, a steel wire rope, and the upper support of a small vehicle, enables the rapid deployment and retrieval of a ship-carrying vehicle.

[0031] 2. This invention uses a camera recognition device for image recognition, combined with an automatic control system of pulley blocks and electromagnets. Only one person is needed to control the launch and retrieval of the aircraft, which can greatly save labor costs.

A pair of claw hooks 17 are hinged on both sides of the connecting post 16, and a connecting post electromagnet 10 is installed inside the connecting post 16. A claw hook electromagnet 12 is installed at the end of each claw hook 17.

[0043] The size of the groove at the stern of the ship is adapted to the size of the small aircraft 5. An upper support 14 is installed on the top of the small aircraft 5. A gripping slot 15 with a size adapted to the claw hook 17 is opened in the middle of the upper support 14. A magnetic block 13 matching the electromagnet 10 of the connecting column is installed on the top of the upper support 14.

[0044] The small vehicle 5 is equipped with a remote control module. The pulley block 6, the connecting column electromagnet 10, the claw hook electromagnet 12, and the remote control module are all electrically connected to the vehicle deployment and retrieval control system inside the ship.

[0045] Furthermore, the connecting post 16 has a mounting groove 8 in the middle, and the connecting post electromagnet 10 is disposed in the mounting groove 8.

[0046] Furthermore, each end of the claw hook 17 is provided with a second mounting groove 9, and the claw hook electromagnet 12 is disposed in the second mounting groove 9.

[0047] Furthermore, a protruding buckle 4 is installed on the top of the upper support 14, and the magnetic block 13 is disposed within the protruding buckle 4.

[0048] Furthermore, a plurality of magnetic blocks 13 are symmetrically arranged inside the protruding buckle 4, and a magnetic isolation plate 11 is provided between each of the plurality of magnetic blocks 13.

[0049] Furthermore, the installation height of the crossbeam 3 is adapted to the draft of the ship and the height of the upper support 14 above the small vehicle 5.

[0050] Furthermore, the pulley block 6 is connected to a lifting drive motor, and the lifting drive motor is equipped with an encoder for calculating the lifting height of the hook device;

[0051] The small vehicle 5 is equipped with a positioning device and a speed adjustment module. When the small vehicle 5 sails into the groove at the stern of the ship, the speed adjustment module controls the speed of the small vehicle 5 to match the speed of the ship.

[0052] Furthermore, the outer wall of the connecting column 16, except for the part at the bottom that contacts the protruding buckle 4, is covered with an anti-magnetic material, and the outer wall of the claw hook 17, except for the gripping end face, is covered with an anti-magnetic material.

[0053] Example 2: This example provides a rapid deployment and retraction device for a vessel based on the stern profile design. It includes an electromagnetic grappling hook device, which is installed at the open crossbeam at the stern and connected to a steel cable within the crossbeam. The steel cable is connected to a fixed pulley system to control the raising and lowering of the grappling hook device. A corresponding electromagnet is installed inside the grappling hook device, and a camera recognition device is installed beside it.

[0054] The top of the upper support of the small aircraft is also equipped with an electromagnetic block that matches the electromagnet. The electromagnetic block of the small aircraft is installed in the protruding part of the upper support. Multiple electromagnetic blocks are symmetrically installed in this part, and each electromagnetic block is equipped with an anti-magnetic partition to prevent the two electromagnetic blocks from attracting each other when they are working.

[0055] Furthermore, fixed pulley blocks and steel wire ropes are symmetrically distributed in the crossbeam. The two ends of the steel wire ropes are connected to the corresponding fixed pulleys, and the middle part is connected to the hook claw device.

[0056] Furthermore, the opening and closing of the claw hook is quickly achieved through the operation of the electromagnet, and the traction steel wire rope of the pulley block is raised and lowered, thereby realizing the rapid deployment and retrieval of the small aircraft.

[0057] Furthermore, except for the direction in which the interaction needs to occur, the rest of each electromagnet is wrapped with a non-magnetic material to prevent the force it generates from having an unnecessary impact on surrounding equipment.

[0058] When the small vehicle reaches the stern of the ship, the miniature camera identifies it and controls the pulley system to lower the grappling hook. After confirming that it has reached the correct position, the grappling hook grabs the slot and is secured by an electromagnet, and the small vehicle is then retrieved from the water and sent into the ship's cabin for maintenance. When it is necessary to deploy the vehicle, the grappling hook grabs it and is lowered by the fixed pulley system and steel cable. When the vehicle reaches the water surface, the camera identifies it and controls the grappling hook to release it, thus deploying the vehicle quickly.

[0063] S13 controls the two claw electromagnets to generate attraction, causing the two claws of the claw device to close and grab the upper support of the small aircraft. At the same time, the connecting column electromagnet is activated to attract the magnetic block installed on the top of the upper support, making the grabbing process more stable and reliable.
