Description

Technical Field

[0001] This invention relates to the field of marine aquaculture technology, and more specifically, to large-scale intelligent marine aquaculture cages for use in deep-sea environments. Background Technology

[0002] Existing deep-sea aquaculture technologies for marine delicacies, including abalone and sea cucumber, mainly rely on fixed net cages, caissons, or hanging cages. The core of these technologies lies in placing the aquaculture units in wind- and wave-resistant boxes or cages, allowing for natural water exchange through the mesh. The advantages are relatively simple structure, controllable investment costs, and successful expansion of aquaculture activities to the deep sea and open ocean, effectively utilizing the superior water quality and wider space of the deep sea.

[0003] Existing technologies mainly employ passive water exchange to exchange water inside aquaculture cages. However, passive exchange is not only inefficient but also fails to create a stable and sufficient directional flow inside the cages, leading to uneven dissolved oxygen distribution and easy accumulation of metabolic waste at the bottom, which is detrimental to the healthy growth of benthic marine products. In addition, the perforated structure of the cages is directly subjected to the impact of ocean currents, which not only accelerates the attachment and blockage of organisms but also easily leads to instability in the internal environment of the aquaculture cages, affecting the growth efficiency of marine products.

[0004] How to invent large-scale, intelligent marine aquaculture cages for deep-sea cultivation to improve these problems has become an urgent issue for those skilled in the art. Summary of the Invention

[0011] Preferably, the reflux tank is equipped with hydraulic medium, the drain pipe is connected to the bottom of the reflux tank, the two ends of the supply pipe are connected to the pump tank and the reflux tank respectively, the pump tank is fitted with a piston, a spring is provided between the piston and the pump tank, the pump tank is fitted with a sealing slider, the energy storage tank is fitted with a piston, a spring is provided between the piston and the energy storage tank, the side wall of the pump tank is provided with a connecting pipe connected to the energy storage tank, and a release pipe is provided between the pump tank and the energy storage tank.

[0012] Preferably, the two ends of the sealing slider are constructed of magnets, the inside of the pump tank is provided with magnets that cooperate with the magnets at both ends of the sealing slider to attract them, and the side wall of the sealing slider is provided with a connecting groove that cooperates with the release pipe.

[0013] Preferably, the wheel rim has a second connecting ring inside, which is connected to the inside of the connecting ring. The piston rod has a liquid passage inside. The inner side of the wheel rim has a channel connecting the flow hole to the liquid passage. The inner side of the connecting ring also has a channel connecting the second connecting ring to the liquid passage.

[0014] Preferably, the wheel rim is internally connected to a valve ring, and the valve ring end is designed with two sets of one-way valve one and one-way valve two in an alternating manner. One-way valve one and one-way valve two are both composed of a set of spring-loaded conical one-way valve structures, and the flow directions controlled by one-way valve two and connecting ring two are opposite.

[0017] In summary, the beneficial effects of this invention are:

[0018] 1. The impeller converts ocean currents in different directions into driving force, which drives the gears to rotate through the supply pipe by continuously driving the liquid medium. The cooperation of the ball bearings and the slide groove makes the piston rod reciprocate periodically along the axis while rotating. When it is close to the aquaculture tank, the relative rotation between the flow hole and the brush bristles can realize the automatic cleaning of the flow hole. At the same time, through the cooperation of the piston rod and the piston chamber, seawater is compressed and discharged through the liquid flow pipe, realizing the automatic flushing and cleaning of the flow hole. It achieves a self-cleaning effect through ocean currents. With the dynamic design of the flow hole, it reduces sedimentation, blockage and biological attachment, and maintains the interaction between the inside and outside of the aquaculture tank.

[0019] 2. By shielding the flow holes with the wheel rim, direct impact from ocean currents into the aquaculture tank can be prevented. Simultaneously, the inner blade design of the drive ring causes the valve ring facing the ocean current to rotate automatically, switching the connection mode between connecting ring one and connecting ring two. This allows the wheel rim on the upstream side of the ocean current to pump liquid into the aquaculture tank while the wheel rim on the other side of the tank simultaneously draws liquid into the tank, achieving small-scale, low-irritation, bidirectional fluid exchange. Compared to traditional natural convection net cages, this method achieves stable and continuous water exchange in ocean current environments, ensuring dissolved oxygen renewal and avoiding the direct impact of irregular ocean currents, thus improving the stability of the marine growth environment.

A connecting ring 407 is provided inside the wheel rim 400. The connecting ring 407 is connected to a liquid flow pipe 402 facing the flow hole 302. The end of the wheel rim 400 that is close to the breeding box 200 is also designed with bristles 401 corresponding to the flow hole 302. A valve ring 412 that controls the connection between the connecting ring 407 and the piston cavity 408 is rotatably connected inside the wheel rim 400. The breeding box 200 is provided with a drive mechanism that provides power to the rotating wheel 205.

[0038] Furthermore, the drive mechanism includes an impeller 201 disposed on the side wall of the breeding tank 200, a gear 206 coaxially connected to the impeller 201, a gear 207 rotatably connected inside the breeding tank 200 and meshing with the gear 206, a cam 208 coaxially connected to the gear 207, an inlet pipe 202 and an outlet pipe 203 connected inside the breeding tank 200, a piston block 209 slidably connected inside the breeding tank 200 and engaging with the cam 208, and a return box 501 and a pumping tank 504 disposed at the bottom of the base 500 for supplying liquid. Pipe 204 extends to the side wall of pump liquid tank 504 and communicates with pump liquid tank 504. A spring for resetting is provided between piston block 209 and breeding box 200. When cam 208 rotates and pushes piston block 209 to perform reciprocating piston movement, medium is drawn from inside return box 501 through one-way valve structure inside inlet pipe 202, discharged into pump liquid tank 504 through one-way flow structure of drain pipe 203, and then discharged into breeding box 200 through supply pipe 204. Energy storage box 503 for energy storage is also provided at the bottom of base 500.

[0039] It should be noted that the return tank 501 contains a hydraulic medium, preferably hydraulic oil. The drain pipe 203 is connected to the bottom of the return tank 501. The supply pipe 204 is connected to the pump tank 504 and the return tank 501 at both ends. After the flow in the breeding tank 200 completes the cleaning of each group, the liquid flows back into the return tank 501 through the supply pipe 204. A piston 505 is fitted inside the pump tank 504. A spring is installed between the piston 505 and the pump tank 504. A sealing slider 506 is fitted inside the pump tank 504.

A one-way valve with the flow direction facing the inside of the energy storage tank 503 is installed inside the connecting pipe 507. A release pipe 508 is installed between the pump tank 504 and the energy storage tank 503. A one-way valve with the flow direction facing the pump tank 504 is installed inside the release pipe 508.

[0040] Furthermore, the two ends of the sealing slider 506 are constructed with magnets, and the inside of the pump liquid tank 504 is provided with magnets that cooperate with and attract the magnets at both ends of the sealing slider 506. The side wall of the sealing slider 506 is provided with a connecting groove 510 that cooperates with the release pipe 508. When the connecting groove 510 moves to a side close to the energy storage box 503, the connecting groove 510 communicates with the release pipe 508.

[0041] Reference Figure 5-11 The wheel rim 400 has a connecting ring 2 406 inside, which is connected to the inside of the connecting ring 411. The piston rod 303 has a liquid passage pipe 304 inside. The inner side of the rotating wheel 2 301 has a channel connecting the flow hole 302 and the liquid passage pipe 304. The inner side of the connecting ring 411 also has a channel connecting the connecting ring 2 406 and the liquid passage pipe 304. When the piston rod 303 moves, the connecting ring 2 406 and the flow hole 302 can be kept connected through the liquid passage pipe 304. It should be noted that a filter screen is installed at the connection point to prevent direct entry and blockage.

[0042] Furthermore, a valve ring 412 is rotatably connected inside the rim 400. The ends of the valve ring 412 are designed with two sets of one-way valve 404 and one-way valve 405 in an alternating manner. Both one-way valve 404 and one-way valve 405 are composed of a set of spring-loaded conical one-way valve structures, and the flow directions controlled by one-way valve 405 and connecting ring 406 are opposite.

[0043] Furthermore, a magnetic block 409 is connected to the outer wall of the valve ring 412. A set of arc-shaped springs for resetting is connected between the magnetic block 409 and the wheel rim 400. A drive ring 403 is connected to the outer wall of the magnetic block 409. The one-way valve 404 is also connected to a set of magnetic blocks 410 that cooperate with the magnetic block 409 to attract magnetic blocks.

[0044] It should be noted that the drive ring 403 is a design with two sets of rings of different diameters, and a set of blades for driving the drive ring 403 to rotate is provided between the two sets of rings.

[0045] The workflow of this large-scale intelligent marine aquaculture cage, applied in deep-sea areas, is as follows:

[0046] In marine aquaculture, a work platform 100 is erected on the ocean surface through offshore infrastructure. A motor on the lifting platform 101 drives a chain distributed in a ring to rotate, which serves as a lifting mechanism to raise and lower the base 500 and the aquaculture box 200 vertically. During aquaculture, the base 500 and the aquaculture box 200 are submerged underwater. It should be noted that, for ease of illustration, the lifting platform 101 can be designed with different heights according to the aquaculture depth requirements to meet the water depth requirements of the aquaculture box 200.

[0047] During the aquaculture process, under the influence of ocean currents, when the current impacts the aquaculture tank 200, it can pass along the surface of the tank 200. When passing the edge area of ​​the tank 200, the impeller 201, which extends to the outside of the tank 200, comes into contact with the ocean current and is driven to rotate. The rotation is transmitted to gear 1 206, and further accelerated by the meshing of gear 1 206 and gear 2 207. This further drives the cam 208 to rotate periodically, pushing the piston block 209 to perform piston movement. Through the connection between the inlet pipe 202 and the return tank 501, the hydraulic oil medium inside the return tank 501 is drawn in unidirectionally. The hydraulic oil medium drawn in is collectively collected by each set of piston blocks 209 and pumped unidirectionally into the pump tank 504 through the drain pipe 203, pushing the piston 1 209 to rotate. A spring between the compression piston 505 and the pump tank 504 ensures that, when the ocean current force is at its normal range, the impeller 201 maintains a speed close to the flow rate of the hydraulic oil pumped into the pump tank 504 and the speed of the hydraulic oil discharged through the supply pipe 204. After entering the pump tank 504, the hydraulic oil enters the aquaculture tank 200 through the supply pipe 204. Passing through the impeller 205, the impeller 205 rotates unidirectionally, thus achieving the transmission and passage of the hydraulic oil medium. The rotation of the impeller 205 drives the gear 3 212 to rotate, which in turn drives the gear belt 211 and the gear 4 300 to rotate synchronously. The rotation of the gear 4 300 drives the impeller 2 301, piston rod 303, and connecting ring 411 to rotate, which in turn drives the ball bearings 305 and the sliding groove 214. The cooperation of the piston rod 303 causes the piston rod 303 to reciprocate along its axis. When the piston rod 303 moves towards the breeding box 200, the spring between the piston rod 303 and the wheel rim 400 first pushes the wheel rim 400 towards the breeding box 200, causing the protruding edge of the wheel rim 400 to contact and support the breeding box 200, bringing the wheel rim 400 close so that the bristles 401 correspond to the flow hole 302. When the rotating wheel 2 301 rotates, due to the limiting connection between the wheel rim 400 and the breeding box 200, the wheel rim 400 can only move along its axis and cannot rotate. At this time, there is relative movement between the bristles 401 and the rotating wheel 2 301. When the gear 4 300 rotates, the bristles 401 can automatically move towards the flow hole 302. Automatic cleaning reduces blockages and adhesion. Simultaneously, the interaction between the ball bearing 305 and the slide groove 214 causes the piston rod 303 to continue moving towards the breeding tank 200. The piston rod 303 compresses the water flow inside the piston chamber 408, pumping the water to the connecting ring 407 via the second check valve 405, and then spraying it out through the liquid flow pipe 402. This, combined with the brush bristles 401, enhances the cleaning effect on the flow hole 302. During the continuous rotation and reset process, the piston rod 303 moves away from the breeding tank 200, reducing the pressure inside the piston chamber 408. This causes the first check valve 404 to move towards the piston chamber 408, creating negative pressure inside the connecting ring 406. This negative pressure then connects the connecting ring 406 to the connecting ring 411 and the liquid flow pipe 304.Through the cooperation of the liquid pipe 304 and the inclined channel inside the rotor 301, water is drawn into the breeding tank 200 through the flow hole 302, guiding the liquid inside the breeding tank 200 to flow towards the flow hole 302.

[0048] It should be noted that the chute 214 is a symmetrical design of two sets of n-shaped grooves with an arc transition at the connection. When the ball bearing 305 slides inside the chute 214, it first drives the piston rod 303 to move along the axial direction when passing through the inclined curve in the middle section, which facilitates pumping or suction of liquid. When the chute 214 is moved to the end close to the inside of the breeding box 200, there is a section of flat and nearly horizontal structure. At this time, the wheel rim 400 and the bristles 401 can be kept close to the flow hole 302 while the rotating wheel 301 is kept rotating, ensuring the stability of cleaning and rinsing work.

[0049] Furthermore, in response to the ocean current direction, the impellers 201 distributed around the edge of the aquaculture tank 200 can collect ocean currents from various directions as driving force. When the ocean current impacts the blades inside the drive ring 403, the wheel rim 400, facing the ocean current direction, can generate a rotational driving force for the drive ring 403. As the drive ring 403 rotates, it causes the first magnetic block 409 to rotate and approach the second magnetic block 410. Simultaneously, the spring between the first magnetic block 409 and the wheel rim 400 is stretched. When the first magnetic block 409 rotates and approaches the second magnetic block 410, the magnetic attraction between them accelerates the first magnetic block 409 towards the second magnetic block 410, thus providing auxiliary power for the rotation of the drive ring 403, thereby driving the valve ring. 412 rotates synchronously, causing the connecting component between piston chamber 408 and connecting ring 407 to change from one-way valve 405 to one-way valve 404, and the connecting component between piston chamber 408 and connecting ring 406 to change from one-way valve 404 to one-way valve 405. At this time, when the pressure inside piston chamber 408 decreases, seawater is drawn into piston chamber 408 through liquid pipe 402, connecting ring 407, and one-way valve 404. When piston rod 303 moves and compresses the inside of piston chamber 408, water can only enter connecting ring 406 through one-way valve 405, then through liquid pipe 304, and then through flow hole 302 into aquaculture tank 200, thus realizing the pumping of fresh seawater into aquaculture tank 200.

[0050] It should be noted that, due to the blade design distributed inside the drive ring 403, only ocean currents that are directly or tangentially distributed towards the end of the drive ring 403 can drive the internal blades of the drive ring 403 to rotate. Through the one-way valve 405, the connecting ring 406 is connected to the piston chamber 408. The piston chamber 408 inside the wheel rim 400, located upstream of the ocean current, pumps liquid towards the aquaculture tank 200. However, the drive ring 403, located downstream of the ocean current, is not directly impacted by the current because it faces away from the current direction. Furthermore, the lateral stress of the drive ring 403 cannot act on the internal blades. This allows the wheel rim 400 on the other side of the aquaculture tank 200, facing away from the ocean current direction, to draw liquid into the aquaculture tank 200 through the flow hole 302. Further, gear 400 is driven by gear belt 211, which in turn is driven by gear 312 and... The first impeller 205 is driven by the liquid flowing through the liquid supply pipe 204. The impeller 205 and the corresponding gear belt 211 and gear 300 driven by the liquid flow through the same set of liquid supply pipes 204 can rotate synchronously, so that the gear 300 can maintain synchronous transmission. When the wheel rim 400 on the upstream side of the aquaculture tank 200 pumps liquid into the aquaculture tank 200, the wheel rim 400 on the other side of the aquaculture tank 200 keeps synchronously drawing liquid from the aquaculture tank 200, realizing small-scale, low-irritation, bidirectional fluid exchange. By shielding the flow hole 302 by the wheel rim 400, the direct impact of the ocean current into the flow hole 302 is prevented from entering the aquaculture tank 200. Compared with the traditional natural convection net cage technology, it can achieve stable and continuous water exchange in the ocean current environment, ensure dissolved oxygen renewal, and avoid the impact of irregular direct impact of ocean current on the growth environment of marine organisms.

[0051] It should be noted that the breeding box 200 is equipped with elastic ratchet teeth with beveled edges to restrict the rotation of the rotating wheel 205 to only rotate in the same direction, thus ensuring the stable rotation of the rotating wheel 205.

[0052] When the ocean current is strong, it increases the rotational speed of impeller 201, thereby increasing the velocity of the liquid pumped into pump tank 504. This velocity exceeds the discharge velocity through supply pipe 204, causing piston 505 to compress the spring between piston 505 and pump tank 504. As piston 505 moves through connecting pipe 507, excess pressurized liquid medium flows unidirectionally into storage tank 503, pushing piston 509 and compressing the spring between piston 509 and storage tank 503 for storage. When the ocean current weakens, piston 505, under the spring force, pumps the medium stored in pump tank 504 through supply pipe 204. The system automatically cleans and exchanges the liquid flow in the inlet pipe 202. As the liquid medium inside the pump tank 504 gradually decreases until the piston 505 moves and contacts the sealing slider 506, it pushes the sealing slider 506 to move. The sealing slider 506 has magnetic structures at both ends. Specifically, the pump tank 504 has a sliding groove for the sealing slider 506 with magnets at both ends that attract and cooperate with the sealing slider 506. When the sealing slider 506 moves, the magnets at both ends cooperate with the magnetic force inside the pump tank 504, causing one end of the magnet to move. The magnetic attraction between the magnet and the pump tank 504 decreases with increasing distance, while the magnetic force between the magnet at the other end and the pump tank 504 increases. This causes the sealing slider 506 to be subjected to a certain external force, allowing the connecting groove 510 to move quickly to the other end. This allows the release pipe 508 to connect with the inside of the pump tank 504 through the connecting groove 510. The unidirectional flow through the release pipe 508 discharges the pressurized liquid inside the piston 2 509 into the pump tank 504, and then into the breeding tank 200 through the supply pipe 204, continuing to achieve stable cleaning and convection effects. The supply pipe 204 provides a stable supply of liquid to the inside of the breeding tank 200. Regarding the constant power, it should be noted that when the ocean current driving force is converted into liquid power and transmitted to the aquaculture tank 200 through the liquid supply pipe 204, since the diameter of the liquid supply pipe 204 is constant and the flow rate per unit time has an upper limit, the power transmitted to the aquaculture tank 200 can maintain a constant and stable state. Therefore, the irregular ocean current force can be converted into stable power to clean the aquaculture tank 200 and improve the convection effect, thus realizing the conversion of ocean current into a stable power driving effect. At the same time, when the ocean current velocity increases, energy can be stored through the pump liquid tank 504 and the energy storage tank 503 and released when the ocean current decreases, maintaining the stability of the automatic cleaning and seawater exchange of the aquaculture tank 200.
