[0002] With the continuous development of large-scale deep-sea aquaculture facilities technology, especially with the increasing application of aquaculture workboats in the deep-sea aquaculture industry, the industry is showing multiple development directions, such as optimizing ship design, increasing the volume of aquaculture water on workboats, improving automation and aquaculture efficiency, and reducing aquaculture costs.
[0003] Because cold-water fish farming requires water from deeper waters, existing water transfer facilities, especially large-scale systems such as those transferring water from the deep sea to ships or aquaculture platforms, necessitate large-diameter, long-distance water transfer devices. Current technologies do not meet relevant technical standards in terms of pipeline design for lowering or retrieving from the ship. The water pipes are subjected to the impact of ocean currents underwater, resulting in significant torque at their base. Furthermore, the torque exerted by the pipe base on the main shaft of the supporting structure is substantial during pipe lowering and retraction. Additionally, when the entire water transfer system is placed on the deck, its length is considerable, occupying significant space and making management and maintenance difficult.
[0004] Currently, the equipment configuration of aquaculture vessels has not effectively solved these problems. In view of this, this application is hereby submitted. Summary of the Invention
[0005] The deep water intake device and the aquaculture vessel used in this application are designed to solve the problems of the prior art by proposing a special mechanism for water intake docking at the ship's side. This mechanism achieves rapid and safe docking with the ship's side water intake by controlling the rotating arm and the slider separately, thus ensuring that the upper root is subjected to less force and that the operation is stable and safe during the water intake process.

[0010] A transverse slider assembly is slidably connected to the second guide rail of the slider assembly. The transverse slider assembly includes a transverse slider frame, on which a mating sleeve, a fifth bearing seat, a second slider, a set of cylinders, and a reinforcing plate are fixedly connected. The two ends of the second threaded shaft are respectively mounted on two sets of fifth bearing seats via fifth bearing shafts. A second square, which serves as a wrench application point, is fixedly connected to one end of the second threaded shaft. A second hole is provided on the reinforcing plate. Each set of mating sleeves is provided with a mating boss for mating positioning and engagement. A sealing ring is provided in the groove opposite to the mating boss. The second slider is slidably connected to the second guide rail, and the cylinder is driven by a piston. Driven by the cylinder, the piston drives the transverse slider assembly to move relative to the slider assembly. The direction of movement of the transverse slider assembly is perpendicular to the ship's side and also perpendicular to the direction of movement of the slider assembly.
[0011] The water intake pipe assembly is composed of multiple sets of water intake pipes spliced together in sequence, with a second elbow connected to one end and a bottom water inlet formed at the other end; a third hole, a fourth hole, and a fifth hole are respectively provided in the multiple sets of water intake pipes; a second elbow reinforcing shaft is welded to the second elbow, and an intermediate sleeve is fitted onto the opening of the second elbow; the second elbow reinforcing shaft and the intermediate sleeve have an axial center line on the same straight line; a docking ring and a docking plate are fixedly connected; the second elbow reinforcing shaft is fitted into the second hole to form an axial reinforcing connection between the water intake pipe assembly and the transverse slider assembly; The outer periphery of the intermediate sleeve is covered with a mating ring and a mating plate is sealed on both sides.

[0018] Example 1: In deep-sea environments, aquaculture vessels need to draw water from the open ocean and transport it onto the ship for the cultivation of various aquatic products in the internal cabins. Since some fish species are cold-water aquaculture species, water needs to be drawn from deeper water layers. Especially for large aquaculture vessels, the water intake system must have a large-diameter, long-distance, and high-strength pipeline configuration.
[0019] like Figures 1 to 23As shown, this application proposes a deep water intake device, which is installed on the deck 2 of an aquaculture vessel 1. Based on the siphon principle, the device uses an existing in-cabin pump set to introduce external seawater into the cabin through the hull inlet assembly 4 on the hull 3, so as to carry out the entire aquaculture process from fish fry to harvest inside the cabin.
[0020] Specifically, if the actual water intake interface were to pass through the deck, the siphon height would be too high and the power requirement would be too great. Therefore, the actual design of the ship's side water intake component 4 is basically located on the side of the ship, about 1 meter above the waterline, to achieve a lower siphon height. Of course, the ship's ballast tanks can also be filled with water, and when taking water from deeper layers in the anchorage, the ship's side water intake can be submerged below the waterline. In this way, a siphon is not required, and the entire process of aquaculture from fry to harvest can be carried out inside the ship's hold.
[0021] The hull inlet assembly 4 includes a hull plate 5 installed on the hull 3 via a first nut 6 and a second nut 7, a first elbow 8 connected to the pump room of the work vessel via the hull plate 5, and a vacuum interface 9 for connecting to an external gas pipeline is provided on the first elbow 8. The deep water intake device includes a base assembly 10 mounted on the deck 2, a moving assembly 20 slidably connected to the base assembly 10, a rotating arm assembly 40 movably connected to the moving assembly 20 in the horizontal direction and rotatable around the main rotating shaft 25, a slider assembly 60 slidably connected to the rotating arm assembly 40, a transverse slider assembly 70 slidably connected to the slider assembly 60, and the end of the water intake pipe assembly 85 away from the bottom water inlet 95 rotatably connected to the transverse slider assembly 70. The water intake pipe assembly 85 is simultaneously traction-connected to the first crane assembly 100 and the second crane assembly 110. The base assembly 10 includes a base 11 fixedly connected to the deck 2. The base 11 is provided with at least one set of main guide rails 19 with different upper and lower guide rail surfaces, a set of drive motors 13 and an array of first bearing seats 12. The two ends of the two sets of lead screws 14 are rotatably connected to the two sets of first bearing seats 12 through a set of first bearings 16 and can rotate around their fixed axes. The drive motors 13 are simultaneously connected to the two sets of lead screws 14. The axial direction of each set of lead screws 14 is perpendicular to the ship's side 3. Specifically, a first synchronous pulley 15 is fitted on one side of each set of lead screws 14, and a second synchronous pulley 17 is fitted on the output end of the drive motor 13. A synchronous belt 18 connects the first synchronous pulley 15 and the second synchronous pulley 17 in series. Under the drive of the drive motor 13, the two sets of lead screws 14 rotate synchronously and in the same direction. A movable component 20 is slidably connected to the base assembly 10. The movable component 20 includes a frame composed of a first frame 21, a second frame 22, and a third frame 23 welded together in sequence. A connecting block 24, a second bearing seat 26, a third bearing seat 29, and a transmission nut seat 32 are installed and connected on the frame.

A roller at the end of the first rotating shaft 27 rolls on the upper rail surface of the main guide rail 19. The second rotating shaft 30 is mounted on the third bearing seat 29 via a second bearing 31. A roller at the end of the second rotating shaft 30 rolls on the lower rail surface of the main guide rail 19. A transmission nut 33, threaded onto the lead screw 14, is fixedly connected to the transmission nut seat 32. Driven by the drive motor 13, the lead screw 14 drives the movable component 20 to move horizontally along a direction perpendicular to the ship's side 3 via the transmission nut 33. The swing arm assembly 40 includes a swing arm 41, one end of a swing arm tie rod 50 is connected to the swing arm 41 via a fourth bearing seat 46, and a first hole 51 is provided at the other end of the swing arm tie rod 50 to serve as a cable hole; A first guide rail 42 is connected along the axial direction of the swing arm 41 (i.e., the length direction of its own frame).

The slider assembly 60 includes a slider frame 61, on which a first slider 62 and a second guide rail 63 are slidably connected to the first guide rail 42. A piston 65 is fixedly connected to the slider frame 61. A slider connector 64 is installed on one side of the slider frame 61 and is connected to the first winch cable 45 via the first cable 120; under the drive of the first winch 44, the first cable 120 drives the slider assembly 60 to move back and forth on the first guide rail 42 via the slider connector 64. A transverse slider assembly 70 is slidably connected along the second guide rail 63 of the slider assembly 60. The transverse slider assembly 70 includes a transverse slider frame 71, and a mating sleeve 72, a fifth bearing seat 75, a second slider 79, a set of cylinders 80 and a reinforcing plate 81 are fixedly connected to the transverse slider frame 71. The two ends of the second threaded shaft 77 are respectively mounted on two sets of fifth bearing seats 75 via fifth bearings 76.

The direction of movement of transverse slider assembly 70 is perpendicular to the ship's side 3 and also perpendicular to the direction of movement of slider assembly 60. The water intake pipe assembly 85 is composed of multiple sets of water intake pipes 91 spliced together in sequence, with a second elbow 86 connected to one side end and a bottom water inlet 95 formed on the other side end; Each of the multiple sets of water intake pipes 91 is equipped with a third hole 92, a fourth hole 93 and a fifth hole 94 respectively; A second elbow reinforcing shaft 90 is welded onto the second elbow 86, and an intermediate sleeve 87 is fitted onto the opening of the second elbow 86. The second elbow reinforcing shaft 90 and the intermediate sleeve 87 have an axial centerline on the same straight line. The mating ring 88 and the mating plate 89 are fixedly connected. The second elbow reinforcing shaft 90 is sleeved in the second hole 82 to form an axial reinforcing connection between the water intake pipe assembly 85 and the transverse slider assembly 70. The outer periphery of the intermediate sleeve 87 is covered with a mating ring 88 and a mating plate 89 is encapsulated on the sides of both. After the mating ring 88 and the mating plate 89 are fixed together, they are nested in the mating boss 73 and form a mutual seal. At the same time, the intermediate sleeve 87 can rotate relative to the mating sleeve 72 on a fixed axis and form a mutual seal. The first crane assembly 100 includes a first crane base 101, a first boom 103 hinged to the first crane base 101 via a first crane shaft 102, a hydraulic cylinder 104 hinged to the first crane base 101, and a hydraulic piston 105 at the output end of the hydraulic cylinder 104 hinged to the first boom 103; driven by the hydraulic cylinder 104, the first boom 103 is rotated relative to the first crane shaft 102 of the first crane base 101 via the hydraulic piston 105; The second winch 106 and the third winch 108 are both fixedly connected to the top of the first boom 103. The second winch 106 pulls the free end of the second winch cable 107, and the third winch 108 pulls the free end of the third winch cable 109.

The fourth winch 111 pulls the free end of the fourth winch cable 112, and the fifth winch 113 pulls the free end of the fifth winch cable 114. The first crane base 101 of the first crane assembly 100 and the second crane assembly 110 are both fixedly connected to the deck 2; the second cable 121 is connected between the third winch cable 109 and the first hole 51; the third cable 122 is connected between the second winch cable 107 and the third hole 92; the fourth cable 123 is connected between the fifth winch cable 114 and the fourth hole 93; and the fifth cable 124 is connected between the fourth winch cable 112 and the fifth hole 94.
[0022] Based on the structural design of the aforementioned deep water intake device, this application also proposes a novel aquaculture vessel, wherein the deep water intake device is installed on the deck 2 of the aquaculture vessel, and a hull inlet assembly 4 connected to the deep water intake device is installed on the hull 3.
[0023] In practical use, when aquaculture vessels do not draw water from deep waters, such as Figure 1 As shown, the moving component 20 is located away from the ship's side 3. The first winch 44 pulls the slider connector 64 through the first cable 120, so that the slider assembly 60 is located close to the main shaft 25. Then, the cylinder 80 drives the piston 65 to move the transverse slider assembly 70 away from the center line of the aquaculture vessel 1. The third winch 108 drives the second cable 121 through the first hole 51 to move the swing arm assembly 40 to a horizontal position. The second winch 106, the fourth winch 111, and the fifth winch 113 respectively pull the third hole 92, the fourth hole 93, and the fifth hole 94 through the third cable 122, the fourth cable 123, and the fifth cable 124 to move the water intake pipe assembly 85 to a horizontal position. Based on this process, all components of the aquaculture vessel are located on the inner side of the hull 3 and / or on the deck 2; at this time, since the slider assembly 60 is located close to the main shaft 25, it is equivalent to the slider assembly 60 driving the transverse slider assembly 70 and the water intake pipe assembly 85 to retract to one end of the swing arm assembly 40 (e.g., Figure 1 and Figure 2 As shown in the figure, the overall length in the horizontal direction has been reduced.
[0024] When aquaculture vessels need to draw water from deep water, the following procedures shall be followed: In the first step, the drive motor 13 moves the moving assembly 20, the first crane assembly 100, and the second crane assembly 110, which carry the boom assembly 40, the slider assembly 60, the transverse slider assembly 70, and the water intake pipe assembly 85, to the outside of the ship's side 3 through the lead screw 14 and the transmission nut 33, while all the devices do not contact the ship's side 3 and the other devices remain stationary; the first crane assembly 100 and the second crane assembly 110 are then driven by the hydraulic cylinder 104 to complete the hydraulic piston 105.
[0025] In the second step, the third winch 108 lowers the boom assembly 40 clockwise through the first hole 51 connected to the second cable 121. At this time, the slider assembly 60, the transverse slider assembly 70, and the water intake pipe assembly 85 remain basically stationary (only moving slightly). Thus, the torque on the main shaft 25 during the lowering process of the boom assembly 40 is very small. When the boom assembly 40 is lowered to the lowest point, the drive motor 13 drives the moving assembly 20 to move towards the ship's side 3. When the lower part of the boom assembly 40 approaches the ship's side connecting plate 5, the first square 48 is rotated manually or automatically, so that the first threaded shaft 47 is screwed into the second nut 7. In this way, the lower part of the boom assembly 40 is firmly fixed to the ship's side connecting plate 5. In the third step, the first winch cable 45, the second winch 106, the third winch 108, the fourth winch 111, and the fifth winch 113 simultaneously drive the slider assembly 60 (carrying the transverse slider assembly 70) and the water intake pipe assembly 85 to move parallel downwards along the first guide rail 42. When they reach the ship's side connecting plate 5, the cylinder 80 pushes the piston 65, causing the transverse slider assembly 70 to move closer to the ship's side connecting plate 5. The second quadrant 78 (multiple) is rotated manually or automatically, and the second threaded shaft 77 is screwed into the first nut 6 to firmly fix the transverse slider assembly 70 to the ship's side connecting plate 5. In the fourth step, the second winch 106, the third winch 108, the fourth winch 111, and the fifth winch 113 drive the water intake pipe assembly 85 to the appropriate water intake position via the second cable 121, the third cable 122, the fourth cable 123, and the fifth cable 124. Fifth, if the hull plate 5 is above the waterline (e.g., 1 meter), partially remove the vacuum through vacuum interface 9, then start the internal pump to draw in deep seawater. If the hull plate 5 is below the waterline (e.g., after the ballast tanks are filled with water), close vacuum interface 9, no vacuuming is needed, and directly start the internal pump to draw in deep seawater, completing the water intake operation. The recycling process for the aforementioned components or devices is carried out in reverse order, and the specific process will not be described in detail here.
[0026] In summary, the embodiments shown in the accompanying drawings are merely preferred solutions for achieving the objectives of this utility model. Those skilled in the art can draw inspiration from this and directly derive other alternative structures that conform to the design concept of this utility model. Other structural features derived therefrom should also fall within the scope of the solutions described in this utility model.
