Description

Technical Field

[0001] This invention relates to the field of aquaculture cage technology, specifically a bottom-mounted, deep-sea intelligent aquaculture cage. Background Technology

[0002] my country boasts the world's largest aquaculture industry, but its land-based and near-shore aquaculture models face bottlenecks such as resource constraints, frequent disease outbreaks, and ecological pressures. Deep-sea areas have become a core growth space for expanding the "blue granary." Traditional floating cages are susceptible to surface currents and waves, have weak disaster resistance, and high maintenance costs, making them unsuitable for the high sea-state environments of deep-sea areas. Bottom-mounted cages have emerged to address this need. With a steel frame as the main body, they are anchored to the seabed via pile foundations or gravity structures, possessing strong typhoon resistance and stability advantages. They can operate stably in open sea areas at depths of tens to hundreds of meters. Their technology integrates marine engineering and intelligent equipment, using corrosion-resistant composite materials to construct the main structure, and incorporating inner and outer netting and dynamic current-reducing designs to effectively resist strong currents and giant waves. In terms of intelligence, they integrate systems for water quality sensing, underwater monitoring, automatic feeding, netting cleaning, and adult fish recovery, relying on 5G and AI. Enables remote real-time control and significantly improves aquaculture efficiency and survival rate. As a core piece of equipment supported by the National Key Research and Development Program, the bottom-mounted net cage has formed a series of engineering solutions, providing key support for the industrialization and large-scale transformation of deep-sea aquaculture in my country.

[0003] In existing technologies, bottom-mounted deep-sea intelligent aquaculture cages mainly suffer from the following technical defects: passive baffles are prone to violent shaking under the impact of ocean currents, forming a turbulent zone behind them, which in turn disturbs the flow field inside the cage; the lifting mechanism relies on high-precision transmission surfaces such as gears and racks, which can easily cause jamming or even deadlock after marine organisms attach to them; and the net cleaning is mostly driven by underwater motors, which are difficult to seal in the high-pressure environment of the deep sea, have a high failure rate, and have high maintenance costs. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] Based on this, the purpose of this invention is to provide a bottom-mounted, deep-sea intelligent aquaculture cage to solve the technical problems of passive baffles in the prior art, which are prone to violent shaking under the impact of ocean currents, forming a turbulent zone behind them, which in turn disturbs the flow field inside the cage; lifting mechanisms rely on high-precision transmission surfaces such as gears and racks, which are prone to jamming or even deadlocking after marine organisms attach; and net cleaning is mostly driven by underwater motors, which are difficult to seal in the high-pressure environment of the deep sea, have a high failure rate, and have high maintenance costs.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a bottom-mounted deep-sea intelligent aquaculture cage, comprising a cage, a first anchoring frame on one side of the cage, multiple sets of guide vanes inside the first anchoring frame, a first mounting box at the top of one set of guide vanes, a second mounting box at the top of the first mounting box, a drive shaft coaxial with the guide vanes inside the first mounting box, a hinged arm on the outside of the drive shaft, a hydraulic damper hinged at one end of the hinged arm, a ratchet at the top of the hinged arm on the outside of the drive shaft, a support frame inside the first mounting box, the support frame cooperating with the ratchet, a speed-increasing gearbox at the top of the drive shaft, a drive wheel at one end of the speed-increasing gearbox, and a chain conveyor belt slidably connected to the outside of the cage whose teeth mesh with the outer side of the drive wheel.

[0008] By adopting the above technical solution, when the net cage is put into use, when the water flow formed by the ocean current or wave surges rapidly impacts the net cage from front to back, the water flow first acts on the multiple sets of guide vanes set on the front side of the net cage. The guide vanes are fixed to the main column on the front side of the net cage by anchoring seats. Each set of guide vanes consists of two pieces, upper and lower, which are rigidly connected by connecting rods. In addition, there are connecting rods inside the first anchoring frame to connect multiple sets of guide vanes, ensuring that the swing amplitude of multiple sets of guide vanes is consistent when impacted by the water flow.

[0009] Furthermore, a movable arm is provided on the outer side of the chain conveyor belt, a movable rod is provided at the top of the movable arm, a second anchoring seat is provided at the bottom of the guide vane, and an anchoring seat is provided at the top of the first anchoring frame.

[0010] By adopting the above technical solution, when the water flow impacts the arc surface of the guide vane, the airfoil-shaped arc surface of the guide vane converts the positive impact force into a lateral diversion force, guiding the water flow to disperse to the left and right sides of the cage, avoiding the water flow from directly entering the cage and impacting the cultured organisms; thereby reducing the direct impact load on the cage body and protecting the cultured organisms inside from stress damage. At the same time, the guide vane is forced to swing by the water flow, and its root shaft rotates accordingly, converting the kinetic energy of the water flow into mechanical rotational energy.

[0011] Furthermore, the first mounting box contains a third mounting box that cooperates with the hydraulic damper, the first mounting box contains a fixed shaft seat that cooperates with the drive shaft, the support frame is bolted to the first mounting box, and the support frame contains a torsion spring that cooperates with the ratchet.

[0012] By adopting the above technical solution, the end of the guide vane's rotating shaft is fixedly connected to the drive shaft. The drive shaft passes through the first mounting box and extends into its interior. A hinge arm is fixed on the outside of the drive shaft. The hinge arm is hinged to one end of the hydraulic damper. The other end of the hydraulic damper is fixed to the inner wall of the first mounting box through the second anchor seat. When the drive shaft rotates with the guide vane, the hinge arm moves synchronously and pushes and pulls the piston rod of the hydraulic damper. The hydraulic damper is filled with hydraulic oil and is equipped with a one-way throttle valve. When the piston rod moves too fast, the hydraulic oil can only flow slowly through the small orifice of the throttle valve, generating a damping force proportional to the speed. This buffers the rotation of the hinge arm, thereby suppressing the swing speed of the guide vane and eliminating the violent vibration of the guide vane in turbulence to the greatest extent. This prevents the formation of periodically falling Karman vortex streets behind the vanes, ensuring a stable flow field inside the net cage and providing a stable water environment for the cultured organisms. The buffered rotational energy continues to be transmitted upward through the drive shaft and enters the interior of the third mounting box.

[0013] Furthermore, the drive shaft and the speed-increasing gearbox are connected by a coupling, a cleaning roller is provided on the outside of the moving rod, and the cleaning roller cooperates with the mesh box. A sealing door is opened at the top of the mesh box, and the speed-increasing gearbox and the drive wheel are connected by a transmission box.

[0014] By adopting the above technical solution, in the third mounting box, the end of the drive shaft is connected to the input lever of the ratchet. The ratchet is fixed to the inner wall of the third mounting box by the support frame. The reciprocating oscillation of the guide vane drives the lever to reciprocate through the drive shaft. The lever pushes the pawl, and the pawl drives the ratchet to rotate intermittently in one direction. No matter whether the guide vane swings to the left or right, the ratchet rotates in the same direction. This ratchet mechanism aims to convert the reciprocating oscillation of the guide vane into unidirectional rotational motion, providing a continuous and stable power source for subsequent transmission.

[0015] Furthermore, the inside of the mesh box is provided with a sliding groove that cooperates with the chain conveyor belt, the outer side of the guide vane is provided with a copper-nickel alloy woven mesh, the bottom of the mesh box is provided with a sliding seat that cooperates with the cleaning roller, the outer side of the cleaning roller is provided with a circular locking cylinder that cooperates with the cleaning bristles, the top of the first mounting box is provided with a reinforcing rib that cooperates with the second mounting box, and the top of the moving arm is provided with a fixing ring that cooperates with the moving rod.

[0016] By adopting the above technical solution, the design of this speed-increasing gearbox aims to increase the slow oscillation frequency of the guide vanes to the working speed required by the cleaning mechanism, thereby achieving mechanical speed increase without electric drive and avoiding potential faults caused by underwater motors and cables.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0019] (1) By setting multiple sets of guide vanes on the front side and equipping them with hydraulic dampers, the vanes can swing smoothly at a controlled speed under the impact of water flow. The damping force generated by the one-way throttle valve inside the hydraulic damper can effectively suppress the violent vibration of the vanes and avoid the formation of periodic Karman vortex streets behind the vanes, thereby eliminating the adverse effects of turbulence on the cultured organisms inside the cage. At the same time, the arc surface of the guide vanes will convert the positive impact force into the lateral diversion force, which will help reduce the direct impact load on the main body of the cage and improve the structural safety and aquaculture environment comfort of the cage under the harsh sea conditions in the deep sea.

[0020] (2) This invention utilizes the reciprocating oscillation of the guide vanes under the action of water flow, converts it into unidirectional rotational motion through a ratchet mechanism, and then drives the chain conveyor belt and cleaning roller to move around the net box after the speed is amplified by the speed-increasing gearbox. The entire cleaning process relies entirely on ocean current energy, without the need to configure underwater motors, cables and sealed chambers and other electrical equipment, effectively avoiding the problems of easy damage to electrical equipment and high maintenance costs in the deep-sea high-pressure environment. The stronger the ocean current, the faster the cleaning roller moves, and the net remains unobstructed, forming a self-regulating cleaning mechanism.

[0021] (3) The present invention coats the outer surface of the guide blade with a copper-nickel alloy metal mesh. This material can continuously release trace amounts of copper ions when immersed in seawater, forming a natural antifouling layer that effectively prevents marine organisms such as barnacles and oysters from attaching and growing on the surface of the blade. This design helps to maintain the smooth shape and flow efficiency of the guide blade for a long time, and avoids the decrease in swing flexibility caused by the weight gain of organisms or surface roughening. At the same time, the continuous scraping of the mesh by the cleaning roller also reduces the attachment of organisms on the mesh and surrounding transmission components. Attached Figure Description

[0033] like Figures 1 to 8As shown, the present invention provides a bottom-mounted intelligent deep-sea aquaculture cage, comprising a cage 1. A first anchoring frame 10 is located on one side of the cage 1. Multiple sets of guide vanes 2 are installed inside the first anchoring frame 10. A first mounting box 4 is located at the top of one set of guide vanes 2. A second mounting box 5 is located at the top of the first mounting box 4. A drive shaft 17 coaxial with the guide vanes 2 is located inside the first mounting box 4. A hinged arm 18 is located on the outside of the drive shaft 17. A hydraulic damper 19 is hinged to one end of the hinged arm 18. A ratchet 15 is located on the outside of the drive shaft 17 at the top of the hinged arm 18. A support frame 16 is located inside the first mounting box 4, and the support frame 16 cooperates with the ratchet 15. A speed-increasing gearbox 12 is located at the top of the drive shaft 17. A drive wheel 14 is located at one end of the speed-increasing gearbox 12. A chain conveyor belt 9, slidably connected to the outside of the cage 1, is engaged with the teeth of the drive wheel 14. The chain conveyor belt 9 runs along the outside of the cage 1. A pre-designed C-shaped chute surrounds and covers the surface of the netting around the net cage 1. When the drive wheel 14 rotates, the chain conveyor belt 9 moves in a circular motion along the chute. A movable arm 8 is fixed to the outside of the chain conveyor belt 9, and a movable rod 11 is connected to the top of the movable arm 8. A cleaning roller 7 is installed on the movable rod 11. It should be noted that a circular locking cylinder is set on the outside of the cleaning roller 7 to cooperate with the subsequent replacement of the brush bristles on the surface of the cleaning roller 7. The slow movement of the chain conveyor belt 9 drives the movable arm 8 and the movable rod 11 to move in a circular motion around the outside of the net cage 1. During the movement, the cleaning roller 7 rolls or scrapes against the surface of the netting, removing biological fouling such as barnacle larvae and algae attached to the netting. This achieves self-cleaning of the netting by utilizing ocean current energy, without the need for external power input. Moreover, the stronger the ocean current, the more violently the guide vane 2 swings, the higher the output speed of the ratchet 15, and the faster the cleaning roller 7 moves, keeping the netting unobstructed, thereby reducing water flow resistance and making the guide vane 2 more effective in guiding the flow.

[0034] For example, a movable arm 8 is provided on the outer side of the chain conveyor belt 9, a movable rod 11 is provided at the top of the movable arm 8, a second anchoring seat 22 is provided at the bottom of the guide vane 2, and an anchoring seat 3 is provided at the top of the first anchoring frame 10. When the net cage 1 is put into use, when the water flow formed by ocean currents or waves rapidly impacts the net cage 1 from front to back, the water flow first acts on the multiple sets of guide vanes 2 provided on the front side of the net cage 1. The guide vanes 2 are fixed to the main column on the front side of the net cage 1 by the anchoring seats 3. Each set of guide vanes 2 includes upper and lower vanes, which are rigidly connected by a connecting rod. The first anchoring frame 10... There are also connecting rods inside to connect multiple sets of guide vanes 2, ensuring that the swing amplitude of multiple sets of guide vanes 2 is consistent when impacted by water flow. When the water flow hits the arc surface of the guide vane 2, the airfoil-shaped arc surface of the guide vane 2 converts the positive impact force into the lateral diversion force, guiding the water flow to the left and right sides of the net cage 1, avoiding the water flow from directly entering the net cage 1 and impacting the cultured organisms; thereby reducing the direct impact load on the main body of the net cage 1 and protecting the cultured organisms inside from stress damage. At the same time, the guide vane 2 is forced to swing by the water flow, and its root shaft rotates accordingly, converting the kinetic energy of the water flow into mechanical rotational energy.

[0035] For example, a third mounting box 20 that mates with the hydraulic damper 19 is provided inside the first mounting box 4. A fixed bearing seat 21 that mates with the drive shaft 17 is provided inside the first mounting box 4. A support frame 16 is bolted to the inside of the first mounting box 4. A torsion spring that mates with the ratchet 15 is provided inside the support frame 16. The end of the rotating shaft of the guide vane 2 is fixedly connected to the drive shaft 17. The drive shaft 17 passes through the first mounting box 4 and extends into it. A hinge arm 18 is fixed to the outside of the drive shaft 17. The hinge arm 18 is hinged to one end of the hydraulic damper 19. The other end of the hydraulic damper 19 is fixed to the inner wall of the first mounting box 4 through a second anchor seat 22. When the drive shaft 17 moves with the guide vane 2, the third mounting box 20 is installed inside the first mounting box 4. When the guide vane 2 rotates, the articulated arm 18 moves synchronously and pushes and pulls the piston rod of the hydraulic damper 19. The hydraulic damper 19 is filled with hydraulic oil and is equipped with a one-way throttle valve. When the piston rod moves too fast, the hydraulic oil can only flow slowly through the small hole of the throttle valve, generating a damping force proportional to the speed, which buffers the rotation of the articulated arm 18, thereby suppressing the swing speed of the guide vane 2, thereby eliminating the violent vibration of the guide vane 2 in the turbulent flow to the greatest extent, preventing the formation of periodically falling Karman vortex streets behind the vane, ensuring the stability of the flow field inside the net cage 1, and providing a stable water environment for the cultured organisms. The buffered rotational energy continues to be transmitted upward through the transmission shaft 17 and enters the interior of the third installation box 20.

[0036] For example, the drive shaft 17 and the speed-increasing gearbox 12 are connected by a coupling. A cleaning roller 7 is provided on the outside of the moving rod 11, and the cleaning roller 7 cooperates with the mesh box 1. A sealing door 6 is opened at the top of the mesh box 1. The speed-increasing gearbox 12 and the drive wheel 14 are connected by a transmission box 13. In the third mounting box 20, the end of the drive shaft 17 is connected to the input lever of the ratchet 15. The ratchet 15 is fixed to the inner wall of the third mounting box 20 by the support frame 16. The reciprocating oscillation of the guide vane 2 drives the lever to reciprocate through the drive shaft 17. The lever pushes the pawl, and the pawl drives the ratchet 15 to rotate intermittently in one direction. No matter whether the guide vane 2 swings to the left or to the right, the ratchet 15 rotates in the same direction. This ratchet 15 mechanism is designed to convert the reciprocating oscillation of the guide vane 2 into unidirectional rotational motion, providing a continuous and stable power source for subsequent transmission.

[0037] For example, the net box 1 has a groove inside that cooperates with the chain conveyor belt 9, the outer side of the guide vane 2 is provided with a copper-nickel alloy woven mesh, the bottom of the net box 1 is provided with a sliding seat that cooperates with the cleaning roller 7, the outer side of the cleaning roller 7 is provided with a circular locking cylinder that cooperates with the cleaning bristles, the top of the first mounting box 4 is provided with a reinforcing rib that cooperates with the second mounting box 5, the top of the moving arm 8 is provided with a fixing ring that cooperates with the moving rod 11. The speed-increasing gearbox 12 is designed to increase the slow oscillation frequency of the guide vane 2 to the working speed required by the cleaning mechanism, so as to achieve mechanical speed increase without electric drive and avoid the potential failure hazards caused by underwater motors and cables.

[0038] The working principle and usage process of this invention: It is deployed in deep sea areas through an external device. The default deployment depth is about 10 meters. The installation direction of the net cage 1 is predetermined according to the direction of the dominant ocean current in the sea area, ensuring that the front of the net cage 1 faces the direction of the incoming wave current.

[0039] When the net cage 1 is put into use, when the water flow formed by the ocean current or the surging waves impacts the net cage 1 from front to back, the water flow first acts on the multiple sets of guide vanes 2 set on the front side of the net cage 1. The guide vanes 2 are fixed to the main column on the front side of the net cage 1 by the anchoring seat 3. Each set of guide vanes 2 includes two pieces, upper and lower, which are rigidly connected by a connecting rod. The first anchoring frame 10 also has a connecting rod inside to connect the multiple sets of guide vanes 2, ensuring that the swing amplitude of the multiple sets of guide vanes 2 is consistent when impacted by the water flow.

[0040] When the water flow impacts the arc surface of the guide vane 2, the airfoil-shaped arc surface of the guide vane 2 converts the positive impact force into a lateral diversion force, guiding the water flow to disperse to the left and right sides of the net cage 1, preventing the water flow from directly entering the net cage 1 and impacting the cultured organisms; thereby reducing the direct impact load on the main body of the net cage 1 and protecting the cultured organisms inside from stress damage. At the same time, the guide vane 2 is forced to swing by the water flow, and its root shaft rotates accordingly, converting the kinetic energy of the water flow into mechanical rotational energy.

[0041] The end of the rotating shaft of the guide vane 2 is fixedly connected to the drive shaft 17. The drive shaft 17 passes through the first mounting box 4 and extends into its interior. A hinge arm 18 is fixed to the outside of the drive shaft 17. The hinge arm 18 is hinged to one end of the hydraulic damper 19. The other end of the hydraulic damper 19 is fixed to the inner wall of the first mounting box 4 through the second anchor seat 22. When the drive shaft 17 rotates with the guide vane 2, the hinge arm 18 moves synchronously and pushes and pulls the piston rod of the hydraulic damper 19. The hydraulic damper 19 is filled with hydraulic oil and is equipped with a one-way throttle valve. When the piston rod moves too fast, the hydraulic oil can only flow slowly through the small orifice of the throttle valve, generating a damping force proportional to the speed, which buffers the rotation of the hinge arm 18, thereby suppressing the swing speed of the guide vane 2, thus eliminating the violent vibration of the guide vane 2 in the turbulent flow to the greatest extent, preventing the formation of periodically falling Karman vortex streets behind the vanes, ensuring the stability of the flow field inside the net cage 1, and providing a stable water environment for the cultured organisms. The buffered rotational energy continues to be transmitted upward through the drive shaft 17 and enters the interior of the third mounting box 20.

[0042] Inside the third mounting box 20, the end of the drive shaft 17 is connected to the input lever of the ratchet 15. The ratchet 15 is fixed to the inner wall of the third mounting box 20 by the support frame 16. The reciprocating oscillation of the guide vane 2 drives the lever to reciprocate through the drive shaft 17. The lever pushes the pawl, and the pawl drives the ratchet 15 to rotate intermittently in one direction. No matter whether the guide vane 2 swings to the left or to the right, the ratchet 15 rotates in the same direction. This ratchet 15 mechanism is designed to convert the reciprocating oscillation of the guide vane 2 into unidirectional rotational motion, providing a continuous and stable power source for subsequent transmission.

[0043] It should be noted that the drive shaft 17 is divided into a front end and a rear end, which are separated by the ratchet 15. Inside the second mounting box 5, the front end of the drive shaft 17 is connected to the input shaft of the speed-increasing gearbox 12. The speed-increasing gearbox 12 adopts a planetary gear set structure and is designed with a speed-increasing ratio of 1 to 20, which can amplify the low-speed input rotation into a high-speed output.

[0044] The speed-increasing gearbox 12 is designed to increase the slow oscillation frequency of the guide vanes 2 to the working speed required by the cleaning mechanism, thereby achieving mechanical speed increase without electric drive and avoiding potential failures caused by underwater motors and cables.

[0045] The output shaft of the speed-increasing gearbox 12 is connected to the transmission wheel 14 through the transmission box 13. The transmission box 13 is equipped with a coupling to ensure the smoothness and centering of power transmission. The outer edge of the transmission wheel 14 is provided with teeth, which precisely mesh with the inner tooth holes of the chain conveyor belt 9 located outside the mesh box 1.

[0046] The chain conveyor belt 9 is arranged around the C-shaped chute pre-set on the outside of the wire mesh box 1, covering the surface of the wire mesh box 1. When the drive wheel 14 rotates, the chain conveyor belt 9 moves in a ring along the chute. A movable arm 8 is fixed on the outside of the chain conveyor belt 9. The top of the movable arm 8 is connected to a movable rod 11. A cleaning roller 7 is installed on the movable rod 11. It should be noted that a circular locking cylinder is set on the outside of the cleaning roller 7 to cooperate with the subsequent cleaning roller 7 to replace the bristles on its surface.

[0047] The slow movement of the chain conveyor belt 9 drives the moving arm 8 and the moving rod 11 to move around the outside of the net box 1. During the movement, the cleaning roller 7 rolls or scrapes against the surface of the net, removing biological fouling such as barnacle larvae and algae attached to the net. This achieves the self-cleaning of the net by utilizing ocean current energy, without the need for external power input. Moreover, the stronger the ocean current, the more violently the guide vane 2 swings, the higher the output speed of the ratchet 15, and the faster the cleaning roller 7 moves, keeping the net unobstructed and reducing water flow resistance, thus making the guide vane 2 more effective at guiding the flow.

[0048] In addition, the outer surface of the guide vane 2 is covered with a copper-nickel alloy metal mesh. This metal mesh continuously releases trace amounts of copper ions when immersed in seawater, forming a natural antifouling layer that effectively prevents marine organisms from attaching and growing on the surface of the guide vane 2, thereby maintaining its guiding and diversion function and swing flexibility for a long time and ensuring the reliability of the entire system.

[0049] When the direction of the ocean current changes, since the installation direction of the cage 1 has been preset according to the dominant ocean current, and the guide vanes 2 are arranged in multiple symmetrical groups, no matter whether the water flow comes from the front side slightly to the left or right, the guide vanes 2 at the corresponding positions can effectively capture energy and complete the diversion and cleaning drive, thus achieving omnidirectional self-adaptation.

[0050] The above embodiments are merely exemplary embodiments of the present invention and are not intended to limit the present invention. The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
