[0036] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0037] Please also read Figure 1 and Figure 2 , the cable recovery device for a ship provided in an embodiment of the present application is now described. The cable recovery device 100 for a ship in this embodiment comprises: a support net assembly 1 and a cable net 2, wherein the support net assembly 1 is arranged on the ship 3, and the cable net is connected to a traction rope on the ship 3. The cable net 2 is detachably connected to the support net assembly 1. The cable net 2 can be separated from the support net assembly 1 in the recovery direction of the ship 3.

[0038] The cable-pulling net 2 is a grid structure formed by flexible ropes arranged in a vertical and horizontal manner. The size of the grid can be adjusted according to the actual situation. The grid used in this embodiment is 150 mm × 150 mm. The shape of the cable-pulling net 2 is generally triangular, circular, square, umbrella-shaped, etc. The specific shape is set according to the position of the supporting net assembly 1 on the hull 3 and the actual use situation. The principle is to ensure that the available area of ​​the cable-pulling net 2 is maximized.

[0039] The edge of the cable guide net 2 is detachably connected to the support net assembly 1. The detachable connection specifically means that the cable guide net 2 can be separated from the support net assembly 1 when it is subjected to a certain external force. Generally, a detachable component is arranged between the cable guide net 2 and the support net assembly 1. For example, a C-shaped elastic lock is used to connect the edge of the cable guide net 2 to the C-shaped elastic lock, and the C-shaped elastic lock is clamped with the support net assembly 1, and the C-shaped elastic lock is ejected from the support net assembly under force. In another embodiment, the cable guide net 2 and the support net assembly 1 are connected by a thin wire. When the cable guide net 2 is subjected to a certain pulling force, and the pulling force is greater than the maximum force of the thin wire, the thin wire is disconnected, and the connection between the cable guide net 2 and the support net assembly 1 is disconnected.

[0040] Further, as the traction rope 4 is pulled out from the tightening device 9 on the hull 3, one end of the traction rope 4 is connected to the traction winch in the locking device 9, and the other end is connected to the edge of the cable net 2. When the cable net 2 is pulled, the traction rope 3 can be pulled out from the locking device 9. In this embodiment, the traction rope 4 is a steel wire rope with a diameter of 6 mm.

[0041] It should be noted that the recovery direction of the hull 3 refers to the direction of the hull 3 returning from the sea surface to the designated target location. It can be the direction from the sea surface to the mother ship, from the sea surface to the shore, or from the surface of various waterways to the land or ship. The recovery direction is consistent with the direction of force on the cable net 2.

[0042] In this embodiment, the cable net 2 is first preset on the support net assembly 1 and is detachably connected to the support net assembly 1. When recovering the hull, by applying tension to the cable net 2, the cable net 2 is guided to move in the recovery direction and detach from the support net assembly 1, thereby pulling the cable net 2 and the traction rope 4 toward the mother ship or the target location for recovery.

[0043] Through the above technical solution, the cable guide net 2 is set on the hull 3 to expand the capture surface of the hull, improve the accuracy and efficiency of the operators on the mother ship to capture the free boats on the sea surface, improve the recovery efficiency of the ship, and simplify the operation of recovering the hull.

[0044] Preferably, the support net assembly 1 includes at least two support rods 5 connected to the hull at one end, and the support rods 5 are spaced a certain distance apart. The cable-pulling net 2 is detachably connected to the two support rods 5 and is supported by the support rods 5. Specifically, the cable-pulling net 2 is connected to the support rods 5 via a buckle 6. The buckle 6 is an elastic ring with an opening, and the edge of the cable-pulling net 2 is connected to the buckle 6, and the buckle 6 is engaged with the support rods 5 through the opening. The cable-pulling net 2 is preset to be detachably engaged with the support rods 5, and the support rods 5 unfold the cable-pulling net 2 to form a flat net suitable for being captured. When the cable-pulling net 2 is pulled, the opening of the buckle 6 opens and detaches from the support rods 5, and the cable-pulling net 2 is then separated from the support rods 5.

[0045] The support rod 5 includes a fixed rod 7 horizontally fixed on the hull 3 and a movable rod 8 vertically arranged on the hull 3. The fixed rod 7 and the movable rod 8 can be arranged in the same plane or in different planes. When the movable rod 8 is arranged on the extension line of the fixed rod 7, the fixed rod 7 and the movable rod 8 are in the same plane. The cable-pulling net 2 is opened in a vertical plane. When the movable rod 8 is arranged on one side of the fixed rod 7, the movable rod 8 and the fixed rod 7 are in different planes, and the cable-pulling net 2 is opened in an inclined plane. It can be understood that no matter whether the cable-pulling net 2 is arranged in a vertical plane or an inclined plane, the purpose of improving the capture efficiency and accuracy can be achieved.

[0046] Furthermore, the movable rod 8 is connected to the hull 3 through a rotating shaft, and the two ends of the cable net 2 are connected to the fixed rod 7 and the movable rod 8 respectively. The rotatable setting of the movable rod 8 increases the setting mode of the cable net 2. When the hull 3 is in the process of sailing, it does not need to be towed or recovered. The opened cable net 2 will cause the hull to be stabbed by debris or animals, affecting the sailing. Therefore, at this time, the movable rod 8 is rotated to be parallel to the deck of the hull 3. The rotation direction of the movable rod 8 can be along the axial extension line of the fixed rod 7, or in a direction perpendicular to the axial extension line of the fixed rod 7. The cable net 2 is laid parallel to the deck of the hull 3, and the connection between the cable net 2 and the fixed rod 7 is not disconnected; when the hull 3 needs to be recovered, the movable rod 8 is rotated to a vertical or inclined position, so that the cable net 2 is propped up and can be hooked or stabbed, and the hull 3 can be better towed or recovered.

[0047] Preferably, the movable rod 8 can be extended and retracted in the axial direction, and the two ends of the cable net 2 are respectively connected to the fixed rod 7 and the movable rod 8. When the cable net 2 is not needed, the movable rod 8 is retracted on the deck of the hull 3, the cable net 2 is folded on the deck, and the connection between the cable net 2 and the movable rod 8 is not disconnected. When the cable net 2 is needed, the movable rod 8 is extended, and the cable net 2 is stretched between the fixed rod 7 and the movable rod 8, so that it can be hooked or stabbed.

[0048] In a preferred embodiment, the number of the support rods 5 is at least three, and the support rods 5 can be extended and retracted along the axial direction, and the cable net 2 is connected to the top of the support rods 5. The edge of the cable net 2 is connected to the top of the support rods 5. When the three support rods 5 are in the same plane, the cable net 2 is unfolded in the vertical plane; when the three support rods 5 are not in the same plane, the cable net 2 is stretched in the plane formed by the three points at the top of the three support rods. Regardless of how it is set, the effect of unfolding the cable net 2 over a large area can be achieved, and the efficiency and accuracy of the cable net 2 being stabbed or hooked can be improved.

[0049] Furthermore, a control unit (not shown in the figure) is also provided on the strut 5, and the control unit has a remote signal receiver, and the control unit is used to control the extension and retraction of the strut 5 or the rotation around the rotating shaft. The remote signal receiver can be an infrared signal receiver or a signal receiver connected by Bluetooth. Through the above technical solution, by using a remote control device such as a remote controller to send a signal to the remote signal receiver on the control unit, the rotation and extension of the strut 5 can be controlled, and then the expansion or contraction of the cable net 2 can be driven, so as to adapt to the application of the hull 3 in different scenarios.

[0050] Another aspect of the present application provides a hull deployment and recovery system, please refer to Figure 2 , including the cable recovery device 100 described in this embodiment, and the traction rope 4 connected to the cable net 2, the traction rope 4 is used to connect with the lifting device and guide the hook of the lifting device to connect with the locking device 9 on the hull 3. Among them, the bottom end of the cable net 2 is connected to the traction rope 4, when the cable net 2 is pulled from the guiding direction, the traction rope 4 is also taken out of the locking device 9. The traction rope 4 is used to connect with the hook of the lifting device, and pull the hook into the tightening device 9, so as to connect the lifting device to the hull 3.

[0051] Furthermore, one end of the towing rope 4 is also connected to two anti-sway ropes 10. The anti-sway rope 10 can be a nylon rope with a diameter of 20 mm. The two anti-sway ropes 10 are respectively connected to the two ends of the hull 3. One anti-sway rope 10 is connected to the bow to control the shaking of the bow of the hull 3, and the other anti-sway rope 10 is connected to the stern to prevent the shaking of the tail of the hull 3. After the anti-sway rope 10 is towed out, the other end is hand-held and controlled by the operator. When the hull 3 is recovered or lowered, the movement of the hull 3 is buffered and shock-absorbed to reduce the shaking of the hull 3 when it is lowered or recovered.

[0052] Further, please refer to Figure 3 The hull deployment and recovery system in the present application also includes a shackle assembly 11. The shackle assembly 11 includes: a lifting ring 12 and a lifting belt 13. The lifting ring 12 is used to connect with the traction rope 4, and then the traction rope 4 is pulled into the locking device 9. The two ends of the lifting belt 13 are respectively connected to the lifting device 15 and the lifting ring 12 through the movable shackle 14. Figure 5, which is a schematic diagram of the structure of the movable shackle 14, the movable shackle 14 includes a buckle 16 and a buckle lock 17. The buckle 16 is an annular rigid structure with an opening, and the buckle lock 17 detachably connects the two ends of the buckle 16. By providing the shackle assembly 11, the lifting ring 12 and the lifting belt 13 can be quickly connected or replaced through the shackle 14, which improves the convenience of installation when the lifting device 15 is lifted and lowered.

[0053] Preferably, the system also includes a net hook 18, such as Figure 5 As shown, the net hook 18 is a rigid rod 20 with a hook 19 at one end. The hook tip of the hook 19 is bent toward the other end of the rigid rod 20. In addition, the rigid rod 20 is also provided with a spike portion 21 at the end near the hook 19, and the spike portion 21 can quickly pass through the hole of the cable net 2, and then the hook 19 of the net hook 18 is recovered to hang the wire of the cable net 2 upside down, so that the net hook is connected to the cable net 2. In a new embodiment, the hook 19 is connected to a flexible rope, and it is obvious that the above-mentioned technical effect can also be achieved, and the net hook 18 can be quickly connected to the cable net 2. Furthermore, the maximum diameter of the hook 19 of the net hook 18 should be smaller than the inner diameter of the cable net grid, so that the net hook is inserted into the cable net 2 to pull the cable net 2.

[0054] Preferably, the hook 19 is also provided with an anti-slip device 24. The anti-slip device 24 is an elastic member provided between the hook 19 and the rigid rod 20. One end of the anti-slip device 24 is fixedly connected to the hook 19, and the other end of the anti-slip device 24 is detachably connected to the rigid rod 20. When the net hook 18 passes through the cable net 2, the spike portion 21 and the hook 19 pass through the holes of the cable net 2 in sequence. The operator lifts the net hook 18 back, the anti-slip device 24 opens, and the cable of the cable net 2 is pulled into the hook 19. The anti-slip device 24 rebounds to lock the cable of the cable net 2 in the space enclosed by the hook 19 and the anti-slip device 24, preventing the cable net 2 from being unhooked.

[0055] The following describes a specific method for deploying a hull using the hull deployment and recovery system in this embodiment, with reference to the accompanying drawings, which includes the following steps:

[0056] Move the hook on the lifting device to above the locking device, lower the hook to the locking device, and connect it to the locking device;

[0057] The lifting device lifts and elevates the hull, and the lifting device moves horizontally and transfers the hull to the water surface;

[0058] When the lifting device lowers the hull to the sea level, the locking device disengages the hook from the locking device, and the hull is unhooked and falls into the water.

[0059] Specifically, the shackle assembly 11 is connected to the hook 21 on the lifting device 15; the shackle assembly 11 is moved above the locking device 9, and the shackle assembly 11 is lowered into the locking device 9 and connected to the locking device 9; the lifting device 15 lifts and raises the hull 3, and the lifting device 15 moves horizontally and transfers the hull 3 to the sea surface; when the lifting device 15 lowers the hull 3 to a height of 0.5 meters above the sea level, the locking device 9 disengages the shackle assembly 11 from the locking device 9, and the hull 3 is unhooked and falls into the water.

The locking device locks the hook, the lifting device is connected to the hull, the lifting device lifts the hull, and then translates the hull back to the target position.

[0065] Specifically, the shackle assembly 11 is connected to the hook 21 on the lifting device 15; the lifting device 15 is started to the top of the hull to be recovered, and the operator 22 stands on the mother ship 23 or the shore, holding the hook 18 to pierce the cable net 2, and the hook tip of the hook 19 of the hook 18 hangs the cable net 2 upside down, and pulls the cable net 2 back into the operator's hand; the cable net 2 is continued to be pulled to drive the traction rope 4 to be pulled out of the locking device 9, and the operator 22 connects the traction rope 4 to the shackle assembly 11; the operator 22 disassembles the anti-sway rope 10 connected to the traction rope 4, and uses it to reduce the shaking of the hull 3 during the lifting and recovery process.
