[0002] There exists a type of vessel that consists of a mother hull and small boats. The mother hull is capable of sailing on its own, while the small boats can either be moored at the stern of the mother hull and sail with it, or they can detach from the mother hull and sail independently, returning to the stern of the mother hull after completing their journey.

[0003] In related technologies, the launching and retrieval operations between the mother ship and the small boat are accomplished using ropes. During the retrieval of the small boat, the crew on the mother ship lowers a rope extended from the winch onto the small boat, and the crew on the small boat then hooks the rope onto the small boat. Finally, the winch retracts the rope, thus retrieving the small boat.

[0004] However, the recycling methods in these technologies are inefficient and pose certain safety risks during operation. Utility Model Content

[0026] In one implementation of this disclosure, the receiving and releasing device further includes a transfer device;

[0027] The transfer device includes a rail and a crane. The length direction of the rail is perpendicular to the length direction of the track. The crane is movably connected to the rail, and the direction of movement of the crane is consistent with the length direction of the rail.

During the retrieval process, the small boat approaches the mother ship and travels along the length of the track towards the locking net until the hook assembly at the bow of the small boat locks with the locking net at the stern of the mother ship. Then, the traction assembly pulls a trolley, causing the trolley to move the locking net towards the bow of the mother ship, which in turn moves the small boat towards the bow of the mother ship until the small boat is in position, completing the retrieval operation.

[0035] In other words, during the recovery of the small boat, there is no need to deploy or lock ropes as described in related technologies, which effectively improves the efficiency and safety of small boat recovery and achieves rapid and safe recovery of the small boat.

[0057] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0058] Figure 1This is a structural schematic diagram of a ship provided in an embodiment of the present disclosure. Because the volume of the mother ship hull 100 is relatively large, Figure 1 Only a portion of the mother ship hull, 100, is shown in the image. See also... Figure 1 In this embodiment, the vessel includes a mother hull 100, small boats 200, and a launching and retrieval device. The launching and retrieval device is a constant tension, two-sided track-type automatic capture and launching device for small boats.

[0059] exist Figure 1 In the middle, the left side is the stern direction of the mother ship 100 and the small boat 200, and the right side is the bow direction of the mother ship 100 and the small boat 200.

[0060] Figure 2 for Figure 1 The left view is shown to better illustrate the retraction channel 1100. Figure 2 The number 200 for the small boat is omitted in the text. Figure 2 The stern of the mother ship 100 has a launching and retraction channel 1100, the length of which is aligned with the length of the mother ship 100. The first end of the launching and retraction channel 1100 is near the bow of the mother ship 100, and the second end is near the stern of the mother ship 100. The second end of the launching and retraction channel 1100 has an opening. A portion of the launching and retraction device is located at the stern of the mother ship 100, and the other portion is located at the bow of the small boat 200.

[0061] During the recovery of the small boat 200, the small boat 200 maintains the same speed as the mother ship 100, and then accelerates towards the opening of the launch and recovery channel 1100, so that the launch and recovery devices on the small boat 200 and the launch and recovery devices on the mother ship 100 are interlocked, thereby enabling docking between the small boat 200 and the mother ship 100, allowing the small boat 200 to be moored at the stern of the mother ship 100.

[0062] See you again Figure 1 In this embodiment, the take-up and take-down device includes a slide rail assembly 10, a trolley 20, a locking net 30, a traction assembly 40, and a hook assembly 50.

[0063] Figure 3 for Figure 1 A top-down view, to better show the extension / retraction channel 1100, Figure 3 The number 200 for the small boat is omitted in the text. Figure 3The slide rail assembly 10 includes two rails 110, which are parallel to each other and spaced apart. The number of trolleys 20 is the same as the number of rails 110. The trolleys 20 are movably connected to their corresponding rails 110. The direction of movement of the trolleys 20 is consistent with the length direction of the rails 110. The locking net 30 is located between the two trolleys 20 and is connected to each of the two trolleys 20. The number of traction components 40 is the same as the number of rails 110. The traction components 40 are connected to their corresponding trolleys 20 to drive the trolleys 20 to move. The hook assembly 50 is used to lock with the locking net 30.

[0064] The launching and recovering device provided in this embodiment involves installing the slide rail assembly 10 and the traction assembly 40 to the stern of the mother ship 100 and the hook assembly 50 to the bow of the small boat 200 during configuration. During the recovery of the small boat 200, the small boat 200 approaches the mother ship 100 and travels along the length of the track 110 towards the locking net 30 until the hook assembly 50 at the bow of the small boat 200 locks with the locking net 30 at the stern of the mother ship 100. Then, the traction assembly 40 pulls the trolley 20, causing the trolley 20 to move the locking net 30 towards the bow of the mother ship 100, which in turn moves the small boat 200 towards the bow of the mother ship 100 until the small boat 200 is in position, completing the recovery operation.

[0065] In other words, during the recovery of the small boat 200, there is no need for the deployment and locking ropes as in related technologies, which effectively improves the efficiency and safety of the recovery of the small boat 200 and achieves rapid and safe recovery of the small boat 200.

[0066] In this embodiment, the slide rail assembly 10 is located inside the launch and take-off channel 1100, and the two tracks 110 are respectively located on the inner sidewall of the launch and take-off channel 1100. The length direction of the track 110 is consistent with the length direction of the launch and take-off channel 1100. The traction assembly 40 is connected to the deck of the mother ship hull 100 and is close to the first end of the launch and take-off channel 1100. The hook assembly 50 is connected to the bow of the small boat 200.

[0067] As mentioned above, the launch and recovery device plays an important role in the rapid and safe recovery of the small boat 200. The launch and recovery device will be described below.

[0068] See you again Figure 1 In this embodiment, the traction assembly 40 includes a fixed pulley 410, a first winch 420, and a second winch 430. The fixed pulley 410 is located at one end of the track 110, and the first winch 420 and the second winch 430 are both located at the other end of the track 110. The rope extending from the first winch 420 is connected to the trolley 20, and the rope extending from the second winch 430 is wound around the fixed pulley 410 and connected to the trolley 20.

[0069] In the above implementation, the direction of the rope extending from the second winch 430 can be changed by the fixed pulley 410, allowing the rope to connect with the pulley 20. In this way, the ropes extending from the first winch 420 and the second winch 430 can be connected to the pulley 20 respectively, forming a closed loop. While the first winch 420 releases the rope, the second winch 430 retracts it, causing the pulley 20 to move towards the stern along the length of the track 110. Conversely, while the first winch 420 retracts the rope, the second winch 430 releases it, causing the pulley 20 to move towards the bow along the length of the track 110.

[0070] For example, both the first winch 420 and the second winch 430 are constant tension winches, which can effectively ensure the driving stability of the first winch 420 and the second winch 430 for the trolley 20.

[0071] In this embodiment, the connection point between the rope extending from the first winch 420 and the pulley 20 is located on the side of the pulley 20 facing the first winch 420, and the connection point between the rope extending from the second winch 430 and the pulley 20 is located on the side of the pulley 20 facing the fixed pulley 410.

[0072] In the above implementation, the connection point between the rope extending from the first winch 420 and the pulley 20 is located on the side of the pulley 20 facing the bow, and the connection point between the rope extending from the second winch 430 and the pulley 20 is located on the side of the pulley 20 facing the stern. In this way, the rope extending from the first winch 420 can pull the pulley 20 towards the bow, and the rope extending from the second winch 430 can pull the pulley 20 towards the stern, thus realizing the reciprocating movement of the pulley 20.

[0073] See you again Figure 3 In this embodiment, the distance between the two first winches 420 is greater than the distance between the two second winches 430 in the length direction perpendicular to the track 110.

[0074] This design allows the first winch 420 and the second winch 430 to be staggered, avoiding interference between the ropes extending from the first winch 420 and the ropes extending from the second winch 430, thereby effectively improving the reliability of the winding and unwinding device.

[0075] For example, in the length direction parallel to the track 110, the distance between the first winch 420 and the fixed pulley 410 is less than the distance between the second winch 430 and the fixed pulley 410.

[0076] This design also allows the first winch 420 and the second winch 430 to be staggered, avoiding interference between the ropes extending from the first winch 420 and the ropes extending from the second winch 430, thereby effectively improving the reliability of the winding and unwinding device.

[0077] See also Figure 3 In this embodiment, the trolley 20 includes a sliding frame 210 and a supporting frame 220. The supporting frame 220 and the sliding frame 210 are connected, and the supporting frames 220 of the two trolleys 20 are opposite to each other. The sliding frame 210 is movably fitted onto the track 110.

[0078] In this embodiment, the sliding frame 210 slides with the track 110 and serves as the mounting base for the support frame 220, enabling the support frame 220 to move together. The support frame 220, as the mounting base for the lock net 30, can support the lock net 30. Furthermore, since the two support frames 220 are arranged opposite each other, they can jointly support the lock net 30 located between the two support frames 220, effectively ensuring the stability of the lock net 30.

[0079] In some examples, the sliding frame 210 and the load-bearing frame 220 are welded together, while in other examples, the sliding frame 210 and the load-bearing frame 220 are bolted together.

[0080] In this embodiment, the side of the supporting frame 220 facing away from the sliding frame 210 has a plurality of locking rings 230. In the length direction perpendicular to the track 110, the plurality of locking rings 230 are arranged at intervals in sequence, and the plurality of locking rings 230 are respectively connected to the locking net 30.

[0081] In the above implementation, the locking ring 230 is used to lock the mesh 30, thereby achieving a stable connection between the mesh 30 and the supporting frame 220.

[0082] In this embodiment, the end of the slide rail has a lug plate, which is fixedly installed on the inner side wall of the take-up and take-down channel 1100 by bolts, thereby achieving a stable connection of the slide rail on the mother ship hull 100.

[0083] In this embodiment, the track 110 is a multi-row track, that is, the track 110 is composed of two parallel sub-tracks 1110, which can effectively improve the stability of the movement of the trolley 20.

[0084] In other embodiments, track 110 can also be selected as a single track or multiple tracks according to actual needs, and this disclosure does not limit it.

[0085] Figure 4 This is a structural diagram of the hook assembly, combined with... Figure 4In this embodiment, the hook assembly 50 includes a base 510, a first hinge arm 520, and a second hinge arm 530. The first ends of the first hinge arm 520 and the first ends of the second hinge arm 530 are spaced apart from each other and respectively hinged to the base 510. The second ends of the first hinge arm 520 and the second ends of the second hinge arm 530 are in contact with each other. The first hinge arm 520 and the second hinge arm 530 are respectively connected to springs 540. The elastic force of the springs 540 keeps the second ends of the first hinge arm 520 and the second ends of the second hinge arm 530 in contact with each other.

[0086] During the process of the hook assembly 50 striking the lock net 30, the lock net 30 pushes the first hinge arm 520 and the second hinge arm 530 to rotate against the elastic force of the spring 540, causing a gap to appear between the second end of the first hinge arm 520 and the second end of the second hinge arm 530. After the lock net 30 passes through the gap, the first hinge arm 520 and the second hinge arm 530 are reset under the elastic force of the spring 540, so that the second end of the first hinge arm 520 and the second end of the second hinge arm 530 re-contact each other, thus realizing the locking of the lock net 30.

[0087] See you again Figure 3 In this embodiment, the retractable device also includes a slide assembly 60, which is located between two tracks 110 and extends along the length of the tracks 110.

[0088] In the above implementation, the sliding plate assembly 60 is located at the bottom of the launching and retracting channel 1100 and can contact the two sides of the small boat 200, thereby supporting the small boat 200 and preventing the small boat 200 from directly contacting the mother ship 100, which would cause damage to the mother ship 100 in the event of an impact.

[0089] For example, the skateboard assembly 60 includes a plurality of sub-skateboards 610, which are arranged in parallel and spaced apart from each other, and all of the sub-skateboards 610 extend along the length direction of the track 110.

[0090] This arrangement of the sub-skateboard 610 ensures that the skateboard assembly 60 can stably support the small boat 200.

[0091] For example, the sub-skateboard 610 is a nylon board.

[0092] Figure 5 This is a diagram illustrating the transfer of ships. Figure 5 perspective and Figure 2 The same perspective, combined Figure 5 In this embodiment, the launching and receiving device further includes a transfer device 70, which includes a suspension rail 710 and a crane 720. The length direction of the suspension rail 710 is perpendicular to the length direction of the track 110. The crane 720 is movably connected to the suspension rail 710, and the moving direction of the crane 720 is consistent with the length direction of the suspension rail 710.

[0093] In the above implementation, the crane 720 can lift the small boat 200 located in the launch channel 1100 and move it along the length of the cabinet, so that the small boat 200 is placed elsewhere, avoiding delaying the launch channel 1100 from launching other small boats 200, thereby further improving the launch efficiency of the small boats 200 of the ship.

[0094] For example, the transfer device 70 is a low-headroom transfer system, which is suitable for environments with low headroom.
