Description

Technical Field

[0001] This application proposes a deep-sea intake ship hull docking and locking device and method for introducing seawater into the internal cabin of a ship for aquaculture in deep-sea environments, belonging to the fields of aquaculture and marine engineering. Background Technology

[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] Existing aquaculture vessels typically employ a closed-hull structure. Water intake is achieved through an inlet at the bottom of the hull, followed by pumping into the hull and then into individual aquaculture ponds. A previously published patent application, CN202510455292.6, entitled "A Deep-Sea Water Intake Cantilever Connecting and Locking Device and Water Intake Method for a Marine Aquaculture Vessel," includes a water intake cantilever, a submersible pump, guide rollers, a rolling element, and a lifting device. The water intake cantilever is connected to the hull via a rotating joint. The position and angle of the cantilever are adjusted using a winch. A temperature sensor at the cantilever end monitors the seawater temperature in real time, and the submersible pump is activated to extract deep-sea water when the temperature reaches a predetermined value. However, due to its flexible short-pipe connection method, the vertical depth of the water intake cantilever is affected by water flow, and the entry of seawater requires manual operation, resulting in insufficient flexibility and stability during the water intake process.

[0004] Since cold-water fish farming requires water from deeper waters, the existing technologies described above do not meet current technical standards in terms of pipeline design for lowering or retrieving from the hull. The pipeline deployment and retrieval efficiency is low, and the corresponding structures still extend beyond the ship's side during navigation. The portion of the hull below the waterline is a load-bearing structure, and openings in this area are generally not permitted, as they would compromise the overall strength of the hull. Therefore, opening the side of the ship's side below the waterline for water intake is clearly unreasonable. Water transport facilities require large-diameter, long-distance pipelines to transport water from the deep sea to the ship. Such devices need to be designed for quick and reliable assembly and disassembly from the ship's side, and for rapid detachment in case of severe weather. Current equipment configurations for aquaculture vessels do not effectively address these issues. Therefore, this patent application is filed. Summary of the Invention

[0008] The base assembly includes a base fixedly connected to the deck. The base is provided with at least one set of first guide rails with different upper and lower guide rail surfaces, a set of first motors, and an array of first bearing seats. The two ends of at least one set of first lead screws are respectively connected to two sets of first bearing seats through a set of first bearings and can rotate around their fixed axes. The first motor drives the first lead screws to rotate axially in a direction parallel to the horizontal surface of the base through at least one set of first transmission components, and the axis of the first lead screws is perpendicular to the ship's side.

[0009] The movable component includes a frame-type body, on which a connecting block and a first lead screw are fixedly installed, and a first lead screw is threaded and screwed to the first lead screw; an array of second bearing seats are fixedly connected to the bottom of the frame; at least two sets of rotating shafts are respectively vertically connected to different sides of one set of second bearing seats, and at least two sets of bearings are each rotatably mounted on the at least two sets of rotating shafts; at least one set of bearings is rollingly connected to the upper rail surface of the first guide rail, at least one set of bearings is rollingly connected to the lower rail surface of the first guide rail, and at least one set of bearings is rollingly connected to the side rail surface of the first guide rail.

[0010] The boom assembly includes a frame assembly consisting of a boom seat, a first boom frame, a second boom frame, and a boom base plate that are fixedly connected to each other. A fifth bearing is sleeved in the through hole of the boom seat and is also sleeved on the main shaft of the moving assembly. At least one set of second guide rails is provided on the first boom frame and / or the second boom frame, and an array of slots is provided on the second guide rails. A first locking block is fixedly connected to the boom base plate. A dual-drive mechanism driven by a second motor is provided between the boom seat and the boom base plate.

[0011] The dual-drive mechanism includes a second motor fixedly connected to the boom mount via a second motor mount. Inside the second motor mount, a sixth bearing is fitted through a third bearing seat. The output shaft of the second motor is driven by a coupling to a set of second lead screws extending along the first or second boom frame. The set of second lead screws is fitted through the sixth bearing and can rotate around its fixed axis. Another set of second lead screws extends along the second or first boom frame. A set of sprockets is fitted on each of the two sets of second lead screws. A chain is wound in a closed loop between the two sets of sprockets.

The slider assembly includes a slider frame, at least one set of third guide rails and fourth guide rails fixedly connected and respectively disposed on both sides of the slider frame, a first slider and a second screw nut; the first slider is slidably connected to the second guide rail of the rotating arm assembly, and the second screw nut is threadedly connected to the second screw.

[0013] A transverse slider assembly is slidably connected along the third and fourth guide rails of the slider assembly. The transverse slider assembly includes a hollow transverse slider body, with a mating sleeve and a cover plate connected to the front and rear ends of the transverse slider body, respectively. A sealing ring is nested in a groove on one side of the mating sleeve, with the inner edge of the sealing ring forming a mating interface. A mating groove is provided on the other side of the mating sleeve. At least one set of second sliders, third sliders, second locking blocks, and transverse limiting blocks are fixedly provided on different outer surfaces of the transverse slider body. A limiting groove is provided on the transverse limiting block, and a second boss is provided on the second locking block. The second locking block has an opening facing the bottom plate of the rotating arm. When the rotating arm assembly is in a vertical position and the slider assembly moves to the end of the rotating arm assembly, the opening of the second locking block can nest and lock the first locking rod or the two can disengage from each other.

[0014] The water intake pipe assembly includes a second elbow, with a rotating ring fixedly connected by a flange at both ends and an array of sequentially spliced ​​water intake pipes. A bottom water inlet is formed at the outer end of the last water intake pipe. At least one set of holes is provided on each water intake pipe. The rotating ring is nested in the docking groove. The second elbow of the water intake pipe assembly can rotate on a fixed axis tightly and in a sealed manner relative to the transverse sliding block assembly.

[0015] Based on the structural design and connection configuration of the deep intake vessel hull docking and locking device described above, this application also proposes the following deep intake vessel hull docking and locking method: The aforementioned docking device is installed on the deck of the aquaculture vessel, and the aforementioned hull inlet assembly is installed on the hull side. After the docking device and the hull inlet assembly are docked and locked in place, the water intake pipe between the two is connected. External seawater is introduced into the cabin through the water intake assembly and the hull inlet assembly, and the entire aquaculture process from fry to harvest is carried out inside the cabin; including the following operation process: Phase 1), outward relocation; The first motor is started to move the moving assembly and its supporting rotating arm assembly, slider assembly, and transverse slider assembly outward from the ship's side via the first lead screw and first lead nut; at the same time, the second hydraulic cylinder is started to operate, and at least one set of crane assemblies moves synchronously and pulls the water intake pipe assembly to the outside of the ship's side. Phase 2) Locking and positioning of the swing arm assembly; First, the first winch pulls the boom assembly to rotate and lower it in the vertical circumferential direction via the first cable. At this time, the slider assembly, the transverse slider assembly, the water intake pipe assembly and the boom assembly remain relatively stationary. Secondly, when the water intake pipe assembly rotates with the swing arm assembly to a distance of 10 to 20° from the vertical position, it pauses, and the first hydraulic cylinder drives the second locking rod to move outward and extend outside the ship's side; Then, the water intake pipe assembly continues to rotate and lower in the circumferential direction until it reaches the vertical position. At this time, the front end of the second locking rod is nested into the groove of the first locking block of the rotating arm assembly. The outer edge of the locking rod at the front end of the second locking rod abuts against the bottom of the first groove, so the second locking rod completely hooks the first locking block. Finally, the first hydraulic cylinder drives the second locking rod to move inward toward the ship's side to tighten the first locking block. At this time, the first boss is completely nested into the first ring of its opposite ship's side connecting sleeve. The first boss extends into and is nested inside the first ring to form a locking mechanism similar to a tenon and mortise. At the same time, the first motor drives the moving assembly and its supporting rotating arm assembly, slider assembly, and transverse slider assembly to move in the opposite direction of stage 1) through the first lead screw and the first lead nut to reduce the deformation of the rotating arm assembly along the ship's side. Thus, the ship's side water inlet assembly applies a locking force to the rotating arm assembly, and finally completes the vertical positioning of the water intake pipe assembly. Phase 3) Locking and positioning of the transverse slider assembly; First, the second motor is started, and the second screw drives the second screw nut to drive the first slider. The slider assembly moves vertically downward along the second guide rail of the rotating arm assembly. At the same time, the transverse slider assembly and the water intake pipe assembly also move vertically downward along with the slider assembly. At least one set of cables pulls the water intake pipe assembly vertically downward under the action of at least one set of winches. Secondly, during the process of the horizontal sliding slider assembly moving vertically downward, when the interface reaches a preset position away from the first bend, the water intake pipe assembly stops moving downward; the first hydraulic cylinder drives the first locking rod to move outward and extend outside the ship's side; Then, the slider assembly continues to carry the transverse slider assembly and the water intake pipe assembly to move vertically downwards until the front end of the first locking rod is nested into the groove of the second locking block, and the outer edge of the locking rod at the front end of the first locking rod abuts against the bottom of the second groove. At this time, the transverse slider assembly and the water intake pipe assembly stop moving downwards. At this time, the limiting groove of the transverse limiting block is located in the groove of the second guide rail to release the restriction of the transverse slider assembly in the direction perpendicular to the ship's side. The transverse slider assembly can be pulled towards the ship's side by the first locking rod through the second locking block. The first locking rod locks and hooks the second locking block completely in the direction perpendicular to the ship's side. Then the second boss can be completely nested into the first ring of the opposite ship's side connecting sleeve. The second boss extends into and is nested inside the first ring to form a locking mechanism similar to a tenon and mortise. Thus, the ship's side water inlet assembly applies a locking force to the transverse sliding block assembly, and finally completes the multi-point docking and locking operation between the water intake pipe assembly and the ship's side water inlet assembly, forming a complete water intake pipeline passage from the outer sea area to the inner cabin. Phase 4) Water intake; At the same time, at least one set of winches is started to drive the bottom inlet of the water intake pipe assembly downward to a suitable sea depth position through at least one set of cables. Finally, the in-cabin pump system is turned on to use siphon effect to introduce deep seawater from the outside into the cabin inside the aquaculture vessel; thus completing the entire water intake operation process.

[0016] In summary, the deep-water intake vessel hull docking locking device and method described herein have the following advantages and beneficial effects: 1. This application achieves rapid and safe docking with the ship's side water intake by controlling the swing arm and the slider separately, thus ensuring that the upper root is subjected to less force and the operation is stable during water intake.

[0017] 2. This application addresses the characteristics of pipelines with large diameters and long-distance transportation by adopting multi-point locking and positioning control methods. This not only effectively counteracts the torsional force on the heel of the water intake pipe fittings when impacted by ocean currents, but also enables rapid assembly and disassembly from the ship's side, significantly improving the connection strength of the water intake and transportation pipeline and achieving high automation efficiency.

Detailed Implementation

[0020] Example 1, such as Figures 1 to 30 As shown, 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. In particular, for large aquaculture vessels, the relevant water intake system needs to have a large-diameter, long-distance, and high-strength pipeline configuration.

[0021] In response, this application proposes a deep-water intake hull docking and locking device, which includes a docking device installed on the deck 2 and a hull inlet assembly 10 installed on the hull 3. Based on the siphon principle and utilizing existing in-cabin pump sets, the docking device introduces external seawater into the cabin through the docked hull inlet assembly 10, enabling the entire process of aquaculture from fry to harvest to be carried out inside the cabin.

[0022] Specifically, the hull inlet assembly 10 includes a hull plate 11 fixedly connected to the hull 3, and a set of hull connecting sleeves 12 each vertically sleeved on the hull plate 11. A first locking drive device (preferably a hydraulic cylinder 13 in this embodiment) is connected along the axial direction of each hull connecting sleeve 12. The output end of each first locking drive device drives a set of first locking rods 15 or second locking rods 16 that are slidably sleeved in the hollow cavity of the hull connecting sleeve 12. The inner ends of the first locking rods 15 or second locking rods 16 are fixedly connected to the output end of the corresponding first hydraulic cylinder 13. Thus, under the drive of the hydraulic cylinder 13, the first locking rods 15 and second locking rods 16 reciprocate linearly within the hull connecting sleeve 12. A recessed first ring 17 is provided at the outer end of each set of hull connecting sleeves 12; and an outwardly protruding locking rod outer edge 19 is provided at the outer end of each set of first locking rods 15 and second locking rods 16. The first locking rod 15 and the second locking rod 16 have the same structure, only differing in the connection position and number on the hull connecting plate 11, which results in a different sequence of locking actions. The front end of the first elbow 9 is fixedly fitted onto the hull plate 11, and its rear end is connected to the hull pump system 4 of the aquaculture vessel 1 through the hull pipe 8. A first valve 6 is installed on the hull pipe 8, and a vacuum interface 18 for connecting to the external gas pipeline is provided on the first elbow 9.

When the rotating arm assembly 50 is in the vertical direction and the slider assembly 70 moves to the end of the rotating arm assembly 50, the opening of the second locking block 87 can be nested to lock the first locking rod 15 or the two can be disengaged from each other.

[0031] The water intake pipe assembly 100 includes a second elbow 101, with a swivel 102 fixedly connected to both ends by a flange 104, and a series of water intake pipes 105 sequentially spliced ​​together. A bottom water inlet 106 is formed at the outer end of the last section of the water intake pipe 105. A second hole 107, a third hole 108, and a fourth hole 109 are respectively provided on the water intake pipe 105. Furthermore, a second elbow reinforcing shaft 103 is welded to the second elbow 101 on the side away from the rotating ring 102. The second elbow reinforcing shaft 103 and the rotating ring 102 have axial center lines on the same straight line. The second elbow reinforcing shaft 103 is sleeved and connected in the cover plate hole 94, thereby forming an axial reinforcing connection between the water intake pipe assembly 100 and the transverse slider assembly 80. The rotating ring 102 is nested in the docking groove 92, and the second elbow 101 of the water intake pipe assembly 100 can rotate on a fixed axis in a tight and sealed manner relative to the transverse slider assembly 80. The first crane assembly 120 and the second crane assembly 128 can adopt the same structural design. The following description takes the first crane assembly 120 as an example.

[0032] The first crane assembly 120 has a first crane base 121 fixedly connected to the deck 2, a first crane shaft 122 and a first pin 124 both axially connected to the first crane base 121, one end of the first boom 123 is hinged to the first crane shaft 122, and a second pin 127 is axially connected to the other end of the first boom 123; one end of the second hydraulic cylinder 125 is hinged to the first pin 124, and the other end is driven to connect to the hydraulic piston 126, which is hinged to the second pin 127.

[0033] The first winch 111 and the second winch 113 are fixedly connected to the first crane assembly 120, and the third winch 115 and the fourth winch 117 are fixedly connected to the second crane assembly 128. The first cable 110 connects the first hole 69 to the output end of the first winch 111; the second cable 112 connects the second hole 107 to the output end of the second winch 113; the third cable 114 connects the third hole 108 to the output end of the third winch 115; and the fourth cable 116 connects the fourth hole 109 to the output end of the fourth winch 117.

[0034] Based on the structural design and connection configuration of the deep intake vessel hull docking and locking device described above, this application also proposes the following deep intake vessel hull docking and locking method: The docking device is installed on the deck 2 of the aquaculture vessel 1, and the hull inlet assembly 10 is installed on the hull 3. When the docking device is docked with the hull inlet assembly 10 and locked in place, the water intake pipe between the two is connected. The water intake pipe assembly 100 introduces external seawater into the cabin through the hull inlet assembly 10, and the entire process of aquaculture from fry to harvest is carried out inside the cabin.

[0035] Specifically, the method for locking the hull of a deep-water intake vessel includes the following operational procedures: Phase 1), outward relocation; First, close the bottom water inlet pipe 5 through the second valve 7; Secondly, the first motor 23 is started to drive the moving assembly 35 and its supporting rotating arm assembly 50, slider assembly 70 and transverse slider assembly 80 to move outward in the direction of the ship's side 3 through the first lead screw 29 and the first lead screw nut 40; at the same time, the second hydraulic cylinder 125 is started to operate, and the first crane assembly 120 and the second crane assembly 128 move synchronously and pull the water intake pipe assembly 100 to move to the outside of the ship's side 3. Phase 2) Locking and positioning of the swing arm assembly 50; First, the first winch 111 pulls the boom assembly 50 to rotate and lower it vertically and circumferentially via the first cable 110 (its actuating end is attached to the first hole 69) (as shown in the figure, it is clockwise). At this time, the slider assembly 70, the transverse slider assembly 80, the water intake pipe assembly 100 and the boom assembly 50 remain relatively stationary. During the process of the boom assembly 50 rotating and lowering circumferentially, the water intake pipe assembly 100 can rotate to a certain extent relative to the transverse slider assembly 80 through the hinge of the main shaft 38, so the torque between the two is relatively small. Secondly, when the water intake pipe assembly 100 rotates with the boom assembly 50 to a distance of 10 to 20° from the vertical position, it pauses. The rotation angle and position can be controlled by pre-setting and dynamically adjusting the motor torque of the first winch 111 and / or the extension length of the first cable 110. When the water intake pipe assembly 100 reaches the pause position, the first hydraulic cylinder 13 drives the second locking rod 16 to move outward and extend outside the ship's side 3. Then, the water pipe assembly 100 continues to rotate and lower in the circumferential direction until it reaches the vertical position. At this time, the front end of the second locking rod 16 is nested into the groove of the first locking block 58 of the rotating arm assembly 50, and the outer edge 19 of the locking rod at the front end of the second locking rod 16 abuts against the bottom 59 of the first groove, so the second locking rod 16 completely hooks the first locking block 58. Finally, the first hydraulic cylinder 13 drives the second locking rod 16 to move inward toward the ship's side 3 to tighten the first locking block 58. At this time, the first boss 60 is completely nested into the first ring 17 of its opposite ship's side connecting sleeve 12. The first boss 60 extends into and is nested inside the first ring 17 to form a locking mechanism similar to a tenon and mortise. Thus, the ship's side water inlet assembly 10 applies a locking force to the rotating arm assembly 50, and finally completes the vertical positioning of the water intake pipe assembly 100. Specifically, the first motor 23 cooperates with the drive moving assembly 35 to move inward toward the ship's side 3. The bottom of the rotating arm assembly 50 is fixedly connected to the ship's side connecting plate 11. Since the top of the rotating arm assembly 50 is connected to the main rotating shaft 38 and forms a hinge with the base assembly 20, the water intake pipe assembly 100 as a whole can be firmly connected through the above two sets of mechanisms. Phase 3) Locking and positioning of the transverse slider assembly 80; First, the second motor 61 is started, and the second lead screw 67 drives the second lead screw nut 75 to drive the first slider 74. The slider assembly 70 moves vertically downward along the second guide rail 56 of the rotating arm assembly 50. At the same time, the transverse slider assembly 80 and the water intake pipe assembly 100 also move vertically downward along with the slider assembly 70. The second cable 112, the third cable 114, and the fourth cable 116 pull the water intake pipe assembly 100 vertically downward under the action of the second winch 113, the third winch 115, and the fourth winch 117, respectively. Secondly, during the process of the horizontal sliding slider assembly 80 moving vertically downward, when the interface 93 reaches the preset position at a distance from the first bend 9, the water intake pipe assembly 100 stops moving downward; the first hydraulic cylinder 13 drives the first locking rod 15 to move outward and extend outside the ship's side 3; Then, the slider assembly 70 continues to carry the transverse slider assembly 80 and the water pipe assembly 100 to move vertically downwards until the front end of the first locking rod 15 is nested into the groove of the second locking block 87, and the outer edge 19 of the locking rod at the front end of the first locking rod 15 abuts against the bottom 91 of the second groove. At this time, the transverse slider assembly 80 and the water pipe assembly 100 stop moving downwards. In other positions, the transverse slider assembly 80 and the slider assembly 70 restrict each other's movement in the direction perpendicular to the ship's side 3. However, the limiting groove 90 of the transverse limiting block 89 has crossed the slot 57 of the second guide rail 56. Therefore, the relative movement restriction between the transverse slider assembly 80 and the slider assembly 70 in the vertical direction is released. Since the first locking rod 15 completely locks and hooks the second locking block 87 in the direction perpendicular to the ship's side 3 (i.e., the horizontal direction), the second boss 88 can be completely nested into the first ring 17 of the opposite ship's side connecting sleeve 12. The second boss 88 extends into and is nested inside the first ring 17 to form a locking mechanism similar to a tenon and mortise. Thus, the ship's side water inlet assembly 10 applies a locking force to the transverse sliding block assembly 80, and finally completes the multi-point docking and locking operation between the water intake pipe assembly 100 and the ship's side water inlet assembly 10, forming a complete water intake pipeline passage from the outer sea area to the inner cabin. Phase 4) Water intake; At the same time, the second winch 113, the third winch 115, and the fourth winch 117 are started to drive the bottom inlet 106 of the water intake pipe assembly 100 downward to a suitable sea depth position through the second cable 112, the third cable 114, and the fourth cable 116. Finally, the in-cabin pump system 4 is turned on to use the siphon effect to introduce deep seawater from the outside into the cabin inside the aquaculture vessel 1. If the centerline of the hull plate 11 is designed to be above the waterline (e.g., 1 meter), the air in the first bend 9 and the internal pipe 8 should be removed first through the vacuum interface 18 (at this time, the second valve 7 should be temporarily closed). After the air is removed, the second valve 7 should be opened and the internal pump system 4 should be started to introduce deep seawater by using siphon effect. If the centerline of the hull plate 11 is designed to be below the waterline (such as after the ballast tank is filled with water), then the vacuum interface 18 should be closed and the internal pump system 4 should be turned on directly to introduce deep seawater.

[0036] This completes the entire water diversion process.

[0037] After the water diversion operation is completed, the process of detaching and recovering the relevant components or devices is carried out in the reverse order of the above steps, and the specific details will not be repeated.

[0038] In summary, the embodiments shown in the accompanying drawings are merely preferred solutions for achieving the objectives of this invention. Those skilled in the art can draw inspiration from these embodiments and directly derive other alternative structures that conform to the design concept of this invention. Other structural features derived therefrom should also fall within the scope of the solutions described in this invention.

10. A method for locking the hull of a deep intake vessel using the deep intake vessel hull locking device as described in any one of claims 1 to 9, characterized in that: The docking device is installed on the deck of the aquaculture vessel, and the hull inlet assembly is installed on the hull side. When the docking device is docked with the hull inlet assembly and locked in place, the water intake pipe between the two is connected. The external seawater is introduced into the cabin through the hull inlet assembly via the water intake pipe assembly, and the entire aquaculture process from fry to harvest is carried out inside the cabin. The following work processes are included: Phase 1), outward relocation; The first motor is started to move the moving assembly and its supporting rotating arm assembly, slider assembly, and transverse slider assembly outward from the ship's side via the first lead screw and first lead nut; at the same time, the second hydraulic cylinder is started to operate, and at least one set of crane assemblies moves synchronously and pulls the water intake pipe assembly to the outside of the ship's side. Phase 2) Locking and positioning of the swing arm assembly; First, the first winch pulls the boom assembly to rotate and lower it in the vertical circumferential direction via the first cable. At this time, the slider assembly, the transverse slider assembly, the water intake pipe assembly and the boom assembly remain relatively stationary. Secondly, when the water intake pipe assembly rotates with the swing arm assembly to a distance of 10 to 20° from the vertical position, it pauses, and the first hydraulic cylinder drives the second locking rod to move outward and extend outside the ship's side; Then, the swing arm assembly continues to rotate and lower in the circumferential direction until it reaches the vertical position. At this time, the front end of the second locking rod is nested into the groove of the first locking block of the swing arm assembly, and the outer edge of the locking rod at the front end of the second locking rod abuts against the bottom of the first groove, so the second locking rod completely hooks the first locking block. Finally, the first hydraulic cylinder drives the second locking rod to move inward toward the ship's side to tighten the first locking block. At this time, the first boss is completely nested into the first ring of its opposite ship's side connecting sleeve. The first boss extends into and is nested inside the first ring to form a locking mechanism similar to a tenon and mortise. At the same time, the first motor drives the moving assembly and its supporting rotating arm assembly, slider assembly, and transverse slider assembly to move in the opposite direction of stage 1) through the first lead screw and the first lead nut to reduce the deformation of the rotating arm assembly along the ship's side. Thus, the ship's side water inlet assembly applies a locking force to the rotating arm assembly, and finally completes the vertical positioning of the water intake pipe assembly. Phase 3) Locking and positioning of the transverse slider assembly; First, the second motor is started, and the second screw drives the second screw nut to drive the first slider. The slider assembly moves vertically downward along the second guide rail of the rotating arm assembly. At the same time, the transverse slider assembly and the water intake pipe assembly also move vertically downward along with the slider assembly. At least one set of cables pulls the water intake pipe assembly vertically downward under the action of at least one set of winches. Secondly, during the process of the horizontal sliding slider assembly moving vertically downward, when the interface reaches a preset position away from the first bend, the water intake pipe assembly pauses its downward movement; the first hydraulic cylinder drives the first locking rod to move outward and extend outside the ship's side; Then, the slider assembly continues to carry the transverse slider assembly and the water intake pipe assembly to move vertically downwards until the front end of the first locking rod is nested into the groove of the second locking block, and the outer edge of the locking rod at the front end of the first locking rod abuts against the bottom of the second groove. At this time, the transverse slider assembly and the water intake pipe assembly stop moving downwards. At this time, the limiting groove of the transverse limiting block is located in the groove of the second guide rail to release the restriction of the transverse slider assembly in the direction perpendicular to the ship's side. The transverse slider assembly can be pulled towards the ship's side by the first locking rod through the second locking block. The first locking rod locks and hooks the second locking block completely in the direction perpendicular to the ship's side. Then the second boss can be completely nested into the first ring of the opposite ship's side connecting sleeve. The second boss extends into and is nested inside the first ring to form a locking mechanism similar to a tenon and mortise. Thus, the ship's side water inlet assembly applies a locking force to the transverse sliding block assembly, and finally completes the multi-point docking and locking operation between the water intake pipe assembly and the ship's side water inlet assembly, forming a complete water intake pipeline passage from the outer sea area to the inner cabin. Phase 4) Water intake; At the same time, at least one set of winches is started to drive the bottom inlet of the water intake pipe assembly downward to a suitable sea depth position through at least one set of cables. Finally, the in-cabin pump system is turned on to use siphon effect to introduce deep seawater from the outside into the cabin inside the aquaculture vessel; thus completing the entire water intake operation process.
