Description

Technical Field

[0001] This application relates to the field of marine equipment technology, and more specifically, to a floating dynamic positioning device for a large-scale, square-coefficient aquaculture vessel with through-flow water intake. Background Technology

[0002] Floating dynamic positioning devices for aquaculture vessels are core equipment for ensuring stable mooring and precise relocation during offshore aquaculture operations. This technology also has a broad application basis and technological commonality in the manufacturing of marine engineering equipment such as polar icebreakers and drop-pipe rock dumpers. Its core function is to counteract external interference from wind, waves, and currents through the coordinated operation of the propulsion system, anchor chain system, and hull structure. Simultaneously, it must be adapted to the block coefficient characteristics of ultra-large hulls (displacement exceeding 10,000 tons) (large beam-to-length ratio, high navigation resistance), and cooperate with the through-water intake channel to achieve seawater recycling.

[0003] In existing technologies, floating dynamic positioning devices for aquaculture vessels mainly adopt a hybrid positioning mode of anchor chain fixation and single propulsion assistance. However, their implementation methods and principles have significant limitations and the following shortcomings:

[0004] 1. Poor adaptability to working conditions and low positioning accuracy: The anchor chain fixing mode is prone to loosening under high sea states, resulting in a large hull offset and failing to ensure the stability of the hull.

[0005] 2. Difficult maintenance and short lifespan of propulsion components: The propulsion positioning structure is exposed for a long time, making it easy for marine organisms to attach, which affects the positioning accuracy. It requires frequent shutdowns and manual diving for cleaning, which is inconvenient and has high maintenance costs.

[0006] In view of this, we propose a highly stable and easy-to-maintain floating dynamic positioning device for ultra-large square-coefficient aquaculture vessels with through-flow water intake. Summary of the Invention

[0020] Beneficial effects: One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0021] 1. By combining "side thruster + full-rotation propulsion + fixed-pitch propeller + anchor chain", it can switch between three modes: transfer (full power coordination), normal aquaculture (anchor chain fixation), and extreme working conditions (combined reinforcement), adapting to different sea conditions and improving the positioning accuracy and stability of the hull.

[0022] 2. The azimuth propulsion component can be raised and lowered, and stored in a storage box when not in operation, which reduces the adhesion rate of marine organisms and the corrosion rate. In addition, when stored, the liquid injection component and the fixed brush mechanism work together to achieve integrated cleaning and lubrication of the azimuth propulsion component without disassembly for maintenance, which improves maintenance efficiency and ensures positioning accuracy.

[0023] 3. The linear driving force is provided by the motor-screw-lifting cylinder transmission chain, which makes the lifting plate rise and fall smoothly. The outer cylinder slides and rises and falls inside the top plate, and the sealing plate fits against the inner wall of the storage box. This not only ensures the lifting accuracy of the lifting plate, but also ensures the sealing accuracy of the storage box, preventing seawater from entering and ensuring the positional accuracy of the full rotation propulsion component when it is stored and extended.

[0040] Reference Figures 1-12 This application provides a floating dynamic positioning device for a super-large square-coefficient aquaculture vessel with through-water intake, including a through-water intake channel 200 inside the hull 100, a mid-pitch propeller 210 near the stern outlet of the through-water intake channel 200, two first anchor chains 400 at the front of the hull 100, a second anchor chain 500 at the rear of the hull 100, two side thrust electric propellers 300 on both sides of the front of the hull 100, and a fixing plate 110 fixed inside the hull 100. A storage box 120 is fixedly mounted through the bottom surface of the fixing plate 110. Two storage boxes 120 are mirror images of each other about the vertical centerline of the fixing plate 110. The storage boxes 120 are connected through the hull. At the bottom of body 100, two support plates 130 are fixed on the top surface of fixed plate 110. A connecting plate 140 is connected between the top side walls of the two support plates 130. A liftable fixed depth component 700 is provided between the bottom surface of the connecting plate 140 and the top surface of fixed plate 110. Full-rotation propulsion components 600 are provided through both sides of the fixed depth component 700. A top plate 121 is fixed on the top surface of storage box 120. The full-rotation propulsion components 600 are connected through the interior of the top plate 121. An injection component 900 and two sets of fixed brush mechanisms 800 are provided through the top surface of the top plate 121. One side of the fixed brush mechanism 800 is connected through the side wall of storage box 120. The two sets of full-rotation propulsion components 600 are pushed up and down by the fixed depth component 700, and have two states.

[0041] In the first state, the full-rotation propulsion component 600 descends, and the bottom of the full-rotation propulsion component 600 extends outward from the bottom of the storage box 120;

[0042] In the second state, the azimuth propulsion assembly 600 rises and its bottom is stored inside the storage box 120. The bottom end of the liquid injection assembly 900 is inserted into the azimuth propulsion assembly 600. The liquid injection assembly 900 is used to add solution into the azimuth propulsion assembly 600. One side of the two fixed brush mechanisms 800 is pushed and inserted into the azimuth propulsion assembly 600 by the fixed depth assembly 700. The fixed brush mechanisms 800 are used to clean the inside of the azimuth propulsion assembly 600.

[0043] By combining "side thruster + full azimuth propulsion + fixed-pitch propeller + anchor chain", it can switch between three modes: transfer (full power coordination), normal aquaculture (anchor chain fixation), and extreme working conditions (combined reinforcement), adapting to different sea conditions and improving the 100 positioning accuracy and stability of the hull.

[0044] The azimuth propulsion component 600 is height-adjustable and can be stored in the storage box 120 when not in use, reducing the adhesion rate of marine organisms and the corrosion rate. Furthermore, when stored, the liquid injection component 900 and the fixed brush mechanism 800 work together to achieve integrated cleaning and lubrication of the azimuth propulsion component 600 without disassembly for maintenance, thus improving maintenance efficiency and ensuring positioning accuracy.

[0045] In this embodiment, the depth-fixing component 700 includes a motor 710 disposed on the top surface of the fixed plate 110. The top of the motor 710 is connected to a first rotating shaft 720. A first positioning ring 721 is sleeved and fixed on the outer wall of the top of the first rotating shaft 720. A screw 740 is connected to the top of the first rotating shaft 720. A lifting cylinder 731 is threaded onto the outer wall of the screw 740. A lifting plate 730 is sleeved and fixed on the outer wall of the lifting cylinder 731. Outer cylinders are fixed on both bottom surfaces of the lifting plate 730. 750, a sealing plate 760 is fixedly fitted to the outer wall of the outer cylinder 750, the outer cylinder 750 is slidably inserted into the inside of the top plate 121, the sealing plate 760 is fitted into the inside of the storage box 120, the inside of the storage box 120 is fixed with a positioning frame 122 for stopping the sealing plate 760, the full rotation propulsion assembly 600 is connected through the inside of the outer cylinder 750, the top surface of the sealing plate 760 is connected through the positioning cylinder 761, and the bottom end of the liquid injection assembly 900 is inserted into the inside of the positioning cylinder 761;

[0046] The linear driving force is provided by the transmission chain of motor 710-screw 740-lifting cylinder 731, and the lifting plate 730 rises and falls smoothly. The outer cylinder 750 slides and rises and falls inside the top plate 121, and the sealing plate 760 is in contact with the inner wall of the storage box 120. This not only ensures the lifting accuracy of the lifting plate 730, but also ensures the sealing accuracy of the storage box 120, preventing seawater from entering and ensuring the positional accuracy of the full-rotation propulsion component 600 when it is stored and extended.

[0047] In this embodiment, the fixed brush mechanism 800 includes a push assembly 810 that penetrates the interior of the top plate 121 and a push brush assembly 830 that is connected to the side wall of the storage box 120. The push brush assembly 830 has a retractable structure inside. A transmission belt 820 connects the push assembly 810 and the push brush assembly 830. The push assembly 810 is located on the top of the sealing plate 760. The bottom surface of the push assembly 810 is higher than the top surface of the push brush assembly 830. The push assembly 810 is pushed by the sealing plate 760 so that the transmission belt 820 drives the push brush assembly 830 to extend and insert into the interior of the full-rotation propulsion assembly 600.

[0048] The sealing plate 760 rises and pushes the push assembly 810, which in turn drives the push brush assembly 830 to extend outward via the transmission belt 820. No additional motor 710 is required, thus reducing overall energy consumption. The lifting and cleaning actions are completed simultaneously, eliminating the need for manual intervention in the cleaning process. This adapts to automated operations and improves maintenance efficiency.

[0049] In this embodiment, the push assembly 810 includes two first gears 814 rotatably connected to the top surface of the top plate 121. One end of each first gear 814 is connected to a first pulley 815. A transmission belt 820 is sleeved on the outer wall of the first pulley 815. One side of each first gear 814 is meshed with a first toothed plate 812. The first toothed plate 812 is penetrated and connected inside the top plate 121. A first push plate 811 is fixed across the bottom surface of the two first toothed plates 812. A second push plate 813 is fixed across the top surface of the two first toothed plates 812. Two first guide rods 816 are penetrated and connected inside the second push plate 813. The first guide rods 816 are connected between the bottom surface of the connecting plate 140 and the top surface of the top plate 121. A second positioning ring 818 is sleeved and fixed on the outer wall of the first guide rod 816. A second spring 817 is sleeved on the outer wall of the first guide rod 816. The second spring 817 is connected between the bottom surface of the second positioning ring 818 and the top surface of the second push plate 813.

[0050] The transmission is stable and efficient through the meshing of two first toothed plates 812 with two first gears 814, and guided by the first guide rod 816. This improves the stability of the drive of the transmission belt 820 and the brush pusher assembly 830. The second spring 817 provides the restoring force, making the operation simple and efficient.

[0051] In this embodiment, the brush push assembly 830 includes a storage box 831 that is fixed through to the side wall of the storage box 120. A second rotating shaft 832 is rotatably connected inside the storage box 831. A second pulley 834 is sleeved and fixed on the outer walls of both ends of the second rotating shaft 832. A transmission belt 820 is sleeved on the outer wall of the second pulley 834. A second gear 833 is sleeved on the outer wall of the second rotating shaft 832. A brushing component 835 is slidably inserted inside the storage box 831. The brushing component 835 is meshed with the bottom of the second gear 833.

[0052] The second shaft 832 is driven by two second pulleys 834 at both ends, and the two brushing components 835 extend and retract synchronously to brush both sides of the propeller blade 640, thereby improving the stability and uniformity of brushing the propeller blade 640.

[0053] The brushing component 835 is telescopic and can be stored inside the storage box 831, reducing space occupation and not obstructing the lifting and lowering movement of the sealing plate 760 inside the storage box 120.

[0054] In this embodiment, the brushing component 835 includes a second toothed plate 8351 that penetrates and connects inside the storage box 831. The top surface of the second toothed plate 8351 is meshed with the bottom of the second gear 833. A limiting plate 8352 is fixed on one side of the second toothed plate 8351. There are two limiting plates 8352 fixed in mirror image about the vertical center line of the second toothed plate 8351. Two second guide rods 8353 are slidably inserted inside the limiting plate 8352. A nylon brush 8355 is fixed across one end of the two second guide rods 8353. A third spring 8354 is sleeved on the outer wall of the second guide rod 8353.

[0055] The third spring 8354 provides elastic pressure, and the nylon brush 8355 conforms to the curved surface of the propeller blade 640, ensuring the cleaning effect on the curved surface of the propeller blade 640 and avoiding scratches, reducing the damage rate of the propeller blade 640, thereby ensuring the propulsion efficiency of the propeller blade 640. The nylon brush 8355 uses high-strength nylon filaments, which extends the service life and shortens the replacement time.

[0056] In this embodiment, the nylon brush 8355 is tilted, and the intersection of the extended lines of the two nylon brushes 8355 is located on the axis of the propeller blade 640 in the second state; the extended lines of the two nylon brushes 8355 intersect at the axis of the propeller blade, ensuring the brushing pressure in the axis area, improving the removal rate of attached substances, and the tilt angle matches the rotation trajectory of the propeller blade, increasing the brushing coverage area and ensuring uniform cleaning of the entire blade.

[0057] In this embodiment, the injection assembly 900 includes an injection tube 910 slidably inserted into the top plate 121. The bottom end of the injection tube 910 is inserted through the sealing plate 760. The injection tube 910 is located at the top of the full-rotation propulsion assembly 600. A third positioning ring 911 is sleeved and fixed to the outer wall of the injection tube 910. The third positioning ring 911 is spaced apart at the bottom of the top plate 121. A fourth spring 920 is sleeved on the outer wall of the injection tube 910. The fourth spring 920 is connected between the bottom surface of the third positioning ring 911 and the top surface of the positioning cylinder 761. Two flapping plates 762 are hinged to the bottom surface of the sealing plate 760 by a torsion spring. The two flapping plates 762 fit against the bottom end of the injection tube 910. A first conduit 950 and a second conduit 980 are connected to the top end of the injection tube 910. A first water pump 940 is connected to one end of a conduit 980, and a first liquid storage tank 930 is connected to the bottom surface of the first water pump 940. A second water pump 970 is connected to one end of the second conduit 980, and a second liquid storage tank 960 is connected to the bottom surface of the second water pump 970. Both the first liquid storage tank 930 and the second liquid storage tank 960 are fixed to the top surface of the top plate 121. A second channel 912 and a third channel 913 are opened inside the injection pipe 910. The second channel 912 is connected to the inside of the first conduit 950, and the third channel 913 is connected to the inside of the second conduit 980. The full-rotation propulsion assembly 600 rises in the second state so that the injection pipe 910 is inserted into the inside of the full-rotation propulsion assembly 600. The second channel 912 and the third channel 913 are respectively connected to the inside of the full-rotation propulsion assembly 600.

[0058] The injection tube 910 is independently equipped with a second channel 912 (cleaning agent) and a third channel 913 (lubricant), which can be injected simultaneously and act on the inside of the azimuth propulsion assembly 600, ensuring the cleaning and lubrication effect inside the azimuth propulsion assembly 600, and improving maintenance efficiency and effectiveness.

[0059] In this embodiment, the full-rotation propulsion assembly 600 includes a drive component 610 fixed to the top surface of the lifting plate 730. A protective cylinder 620 is connected to the bottom surface of the drive component 610. The protective cylinder 620 is connected through the interior of the outer cylinder 750. A guide pipe 630 is fixed to one side of the protective cylinder 620. A propeller blade 640 is rotatably connected inside the guide pipe 630. One end of the drive component 610 is connected through the interior of the protective cylinder 620 and the guide pipe 630. One end of the drive component 610 is drivenly connected to the propeller blade 640. A first through hole 631 is opened on the top surface of the guide pipe 630. The first through hole 631 and the liquid injection pipe 910 are located on the same vertical centerline.

[0060] By opening a first through hole 631 on the guide tube 630 and setting the first through hole 631 and the injection tube 910 on the same vertical center line, the injection tube 910 can be accurately connected to the inside of the guide tube 630, and the bottom end of the injection tube 910 can accurately reach the top of the propeller blade 640, which facilitates the direct injection of cleaning agent into the propeller blade 640 and improves the convenience of cleaning the propeller blade 640.

[0061] In this embodiment, a valve cylinder 634 is inserted inside the guide tube 630. A first spring 633 is connected between one end of the valve cylinder 634 and the inside of the guide tube 630. One end of the valve cylinder 634 is connected to the inside of the first through hole 631. A sealing ring 635 is embedded and fixed in the inner wall of the first through hole 631. One end of the valve cylinder 634 is inserted into the sealing ring 635. A first channel 632 is opened inside the guide tube 630. One end of the first channel 632 is opened in the valve cylinder 634. 4. At the bottom, the other end of the first channel 632 is opened at the rotating end of the propeller blade 640. The bottom surface of the valve cylinder 634 is provided with a second through hole 6341. The bottom end of the third channel 913 is opened through the bottom side wall of the injection pipe 910. The valve cylinder 634 is inserted into the first through hole 631 through the injection pipe 910 and pushed into the guide pipe 630, so that the third channel 913, the valve cylinder 634, the second through hole 6341 and the interior of the first channel 632 are connected.

[0062] When the injection tube 910 is inserted, it opens the valve cylinder 634, and the second through hole 6341 automatically aligns with the first channel 632 without manual adjustment. The first channel 632 directly reaches the rotating end of the propeller blade 640, which improves the utilization rate of lubricating fluid, shortens the lubrication operation time, and improves the lubrication effect. It also reduces the wear rate of the propeller blade 640, extends the maintenance cycle, reduces the frequency of maintenance, and lowers labor costs.

[0063] Specifically, the positioning device is set according to different working conditions;

[0064] When the working condition is a transfer condition, a combined positioning scheme is adopted: "300 bow side thrust electric propulsion unit + 600 stern full rotation propulsion unit + 210 mid-pitch propeller full power coordinated drive + three-point anchor chain full retraction", and the transfer propulsion efficiency is improved by utilizing the wake effect of the 200 through water intake channel.

[0065] When the working conditions are normal aquaculture conditions, a single positioning scheme is adopted: "three-point anchor chain fixed positioning" to reduce the floating energy consumption of ultra-large hulls by 100.

[0066] When the working conditions are extreme aquaculture conditions, a combined positioning scheme is adopted: "300 bow side thrusters + 600 stern azimuth propulsion components + 210 mid-pitch propellers + three-point anchor chains" to enhance the wind and wave resistance of the super-large hull by 100.

[0067] When the azimuth propulsion assembly 600 is used for positioning, the first rotating shaft 720 is driven to rotate by the starter motor 710. The first rotating shaft 720 drives the screw 740 to rotate, and the screw 740 pushes the lifting plate 730 to descend. The lifting plate 730 drives the azimuth propulsion assembly 600 to descend, so that the bottom end of the azimuth propulsion assembly 600 extends out of the bottom of the storage box 120. The drive component 610 is then activated to drive the propeller blade 640 to rotate inside the guide tube 630. The drive component 610 adopts the same drive structure as the existing azimuth propeller, mainly composed of a servo motor 710, a transmission shaft, a transmission gear, and a reduction gearbox, to drive the propeller blade 640 to rotate for propulsion and positioning of the hull 100.

[0068] When the azimuth propulsion assembly 600 is not in use, the motor 710 is started to push the lifting plate 730 to rise, so that the azimuth propulsion assembly 600 is retracted into the storage box 120 to protect the propeller blade 640 at the bottom. At the same time, the lifting plate 730 drives the outer cylinder 750 to rise, and the outer cylinder 750 drives the sealing plate 760 to slide and rise against the inner wall of the storage box 120. The sealing plate 760 drives the liquid injection pipe 910 to rise inside the top plate 121.

[0069] After the sealing plate 760 rises above the height of the storage box 831, the sealing plate 760 begins to push the two first push plates 811 simultaneously. The first push plates 811 drive the two first toothed plates 812 to rise, and the first toothed plates 812 drive the second push plate 813 to rise. The second push plate 813 rises along the two first guide rods 816 and compresses the second spring 817. At the same time, the first toothed plate 812 meshes with the first gear 814 for transmission, and is transmitted through the first pulley 815, the transmission belt 820 and the second pulley 834, so that the second rotating shaft 832 drives the second gear 833 to rotate. The second gear 833 meshes with and pushes the second toothed plate 8351, so that the nylon brush 8355 extends out of the storage box 831 and extends into the storage box 120 from both sides until the propeller blade 640 rises and is positioned. The nylon brush 8355 elastically adheres to the side wall of the propeller blade 640.

[0070] Meanwhile, the third positioning ring 911 on the injection tube 910 fits against the bottom surface of the top plate 121. As the sealing plate 760 continues to rise, the injection tube 910 slides inside the sealing plate 760. The bottom end of the injection tube 910 pushes open the flap 762, the positioning cylinder 761 rises and compresses the fourth spring 920 until the guide tube 630 rises. The bottom end of the injection tube 910 is inserted into the first through hole 631. The bottom outlet of the second channel 912 stops at the top of the propeller blade 640. The injection tube 910 pushes the valve cylinder 634 into the guide tube 630. The valve cylinder 634 compresses the first spring 633. The second through hole 6341 on the bottom surface of the valve cylinder 634 is connected to the first channel 632.

[0071] Then, the first water pump 940 is started to introduce the cleaning agent inside the first storage tank 930 into the second channel 912 through the first conduit 950, and then discharge it onto the propeller blade 640 through the second channel 912. The second water pump 970 is started to introduce the lubricating fluid inside the second storage tank 960 into the third channel 913 through the second conduit 980, and inject it into the rotating end position of the propeller blade 640 through the valve cylinder 634, the second through hole 6341, and the first channel 632. The drive component 610 is then started to make the propeller blade 640 rotate inside the guide pipe 630. The cleaning agent and the nylon brush 8355 are used to brush both sides of the propeller blade 640 to remove the adhering substances on the surface of the propeller blade 640 and to lubricate the propeller blade 640, ensuring the rotational stability of the propeller blade 640, thereby ensuring the accuracy and stability of the overall positioning of the device for the hull 100.
