Description

Technical Field

[0001] This invention relates to the field of marine aquaculture, and more particularly to a multifunctional aquaculture system for nearshore marine ranches. Background Technology

[0002] As an important supplement to global fishery resources, nearshore aquaculture, while meeting human protein needs, also faces a series of complex challenges. For example, extreme weather events such as typhoons and storm surges can instantly destroy aquaculture cages, causing fish to escape or die; or climate change or environmental pollution can cause sudden changes in marine water quality, leading to eutrophication, which may exceed the tolerance range of target fish species, resulting in stunted growth or increased mortality; traditional feeding relies on manual labor or fuel-powered equipment, while offshore aquaculture requires ship transportation, resulting in high energy consumption; most aquaculture farms rely on manual water quality monitoring, making it difficult to monitor key parameters such as dissolved oxygen and pH in real time, and the response speed to disaster warnings is insufficient.

[0003] In view of this, the present invention is hereby proposed. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the present invention provides a multifunctional aquaculture system for nearshore marine ranches, which is mainly to solve the problems of low aquaculture efficiency caused by the simple structure of the aquaculture tank, inability to cope with extreme weather, reduced seawater quality due to environmental pollution, and insufficient disaster early warning response in the prior art.

[0005] The technical solution of the present invention is as follows:

[0006] A multifunctional aquaculture system for nearshore marine ranching includes:

[0007] The breeding box has a cylindrical structure;

[0008] A magnetic levitation power system is installed at both ends of the breeding box, including an inner ring component and an outer ring component arranged concentrically. The inner ring component is connected to the breeding box to support the breeding box. The outer ring component is magnetically connected to the inner ring component and is magnetically levitated by the inner ring component and drives the inner ring component to rotate, thereby driving the breeding box to rotate.

[0009] The buoy, being a hollow structure, is disposed at least at both ends of the aquaculture tank and connected to the outer ring assembly to provide buoyancy;

[0010] An intelligent monitoring and control system is connected to the aquaculture tank to at least control the floating depth of the aquaculture tank in seawater;

[0011] A multi-source clean energy system is electrically connected to the inner and outer ring components to provide power.

[0012] This invention integrates a magnetic levitation system with an aquaculture tank. The magnetic levitation power system drives the tank to rotate continuously at a low speed, reducing the entanglement and attachment of aquatic plants and preventing the farmed organisms from breaking through the netting and escaping, thus significantly improving dissolved oxygen efficiency. A multi-source clean energy system constructs a composite energy storage system to provide continuous power for the entire system. The intelligent monitoring and control system dynamically regulates water quality parameters through precise monitoring. It can also be used to issue alarms for impacts from seawater and large alien organisms, adjust the position of the aquaculture tank, and reduce damage to the tank caused by natural disasters. The combination of these systems can greatly improve the efficiency of nearshore aquaculture and achieve a virtuous cycle of resources and energy through a self-sufficient ecosystem.

[0013] In a preferred embodiment, the inner ring assembly includes an inner ring and a central shaft, as well as inner ring spoke links, inner ring annular links, and inner ring longitudinal links; wherein

[0014] The inner ring is a rotor, installed at both ends of the central shaft, which passes through the center line of the breeding box. The inner ring spoke connecting rods are connected between the inner ring and the inner ring annular connecting rods. The inner ring longitudinal connecting rods are connected longitudinally between two adjacent sets of the inner ring annular connecting rods, thus forming an inner frame to support the breeding box.

[0015] In a preferred embodiment, the outer ring assembly includes an outer ring, an outer ring spoke connecting rod, an outer ring annular connecting rod, and an outer ring longitudinal connecting rod; wherein

[0016] The outer ring has a winding coil inside, and the outer ring radial connecting rod is radially connected between the outer ring and the outer ring annular connecting rod.

[0017] In a preferred embodiment, the outer ring is further provided with a sensor, a controller, and a power amplifier. The sensor detects the position of the rotor shaft center and transmits a signal to the controller when the rotor deviates from the shaft center position. The controller automatically adjusts the number of coil turns and the coil current through its built-in program, thereby adjusting the magnetic field strength and electromagnetic force in different directions until the rotor is located at the shaft center.

[0018] In a preferred embodiment, the intelligent monitoring and control system includes an air inlet / vent at the top of the pontoon and an air inlet / vent at the bottom of the pontoon. The intelligent monitoring and control system monitors seawater quality data to regulate the air and water content inside the pontoon, thereby fine-tuning the floating depth of the aquaculture tank in the seawater to the optimal aquaculture environment position.

[0019] In a preferred embodiment, the intelligent monitoring and control system further includes:

[0020] An impact warning unit is installed at multiple locations in the breeding box to detect the impact that the breeding box will receive.

[0021] The floating box lifting and limiting device is slidably connected to the floating box at least at both ends of the aquaculture box. It is used to reduce the floating depth of the aquaculture box to a safe depth and limit it when an impact is detected to be coming or about to come, thereby reducing the impact of the impact on the aquaculture box.

[0022] In a preferred embodiment, the collision warning unit includes:

[0023] Accelerometers are used to detect vibrations or impacts in the breeding tank.

[0024] Ultrasonic sensors detect obstacles by reflecting sound waves.

[0025] Pressure sensors are used to monitor changes in water pressure and determine if there is any collision with an object;

[0026] Infrared sensors use infrared light to detect the approach of objects;

[0027] An alarm is used to sound an alarm when an impact is detected, so as to promptly remind the user.

[0028] In a preferred embodiment, the float lifting and limiting device includes:

[0029] The pontoon slide is engaged with both sides of the pontoon, allowing the pontoon to slide up and down within the slide.

[0030] The anchor chain and counterweight anchor are installed in the chute. One end of the anchor chain is connected to the pontoon and the other end is connected to the counterweight anchor on the seabed. When the pontoon needs to be lowered or raised, the length of the anchor chain is adjusted so that the pontoon can maintain a balanced state at the corresponding height.

[0031] In a preferred embodiment, the intelligent monitoring and control system further includes:

[0032] The water quality monitoring unit is used to monitor the water environment indicators of the water body where the aquaculture tank is located in real time.

[0033] The intelligent water quality control unit is automatically activated when water environmental indicators exceed thresholds to dynamically regulate water quality parameters.

[0035] Tidal turbine generator set;

[0036] Wave energy conversion device;

[0037] Photovoltaic power generation modules; and

[0038] Intelligent energy storage module;

[0039] By using a composite energy storage system to continuously supply and store energy for the system equipment around the clock, we can make deep and effective use of marine renewable energy and reduce pollution to the marine environment.

[0040] In a preferred embodiment, it further includes:

[0041] An ecological purification system is installed on the breeding tank and in the water area near the breeding tank to perform ecological purification of the breeding tank and the water area near the breeding tank.

[0042] In a preferred embodiment, the ecological purification system includes:

[0043] The primary purification biodegradation device involves installing a hanging box on the breeding box, filling the inside with porous material and adding compound microbial agents, which degrades ammonia nitrogen and nitrite through nitrification / denitrification.

[0044] The secondary purification plant absorption device involves placing a floating planting platform at a certain distance near the breeding box to absorb nitrates and phosphates, improve the aquatic environment, and release oxygen.

[0045] The three-stage purification and animal control device is suspended in the mid-water layer of the sea area where the breeding tanks are located to remove organic debris and control excessive algae growth.

[0046] The advantages of this invention over the prior art are:

[0047] 1. The magnetic levitation power system provided by this invention adopts non-contact electromagnetic drive technology. By adjusting the number of coil turns and coil current, the electromagnetic field strength and electromagnetic force are intelligently adjusted, enabling the aquaculture tank to maintain adaptive and stable rotation in complex marine environments. This effectively reduces the entanglement and attachment of aquatic plants and enhances the dissolved oxygen capacity of the water, preventing the aquatic organisms from destroying the tank and escaping, thus avoiding economic losses and environmental pollution. The rotating shaft has no mechanical contact, requires no lubrication, is suitable for all liquids, and has a wide applicable temperature range. While reducing mechanical wear, it improves the system's environmental adaptability, forming an energy-saving and environmentally friendly drive system.

[0048] 2. This invention combines a magnetic levitation system with a breeding box. The breeding box provides basic breeding functions while being integrated with the magnetic levitation power system (mainly manifested in the integration of the breeding box and the inner ring components). The magnetic levitation power system not only provides driving force but also serves as the main structure of the breeding facility to some extent. There is no need to set up additional breeding facilities or driving systems. The structure is simple, compact, and easy to implement.

[0049] 3. The intelligent monitoring and control system used in this invention can adjust the depth of the tank, allowing for both fine-tuning and large-scale rapid adjustments. By fine-tuning the depth of the tank, it can float at the optimal breeding depth. By making large-scale rapid adjustments, it can sink the breeding tank to the seabed and limit its position before a storm arrives, thereby effectively avoiding the impact of severe sea conditions and extreme weather such as typhoons, reducing damage to the breeding tank, and reducing economic losses.

[0050] 4. This invention monitors the water environment indicators in the water tank in real time through a water quality monitoring device, collects waste and purifies the water through an ecological purification system, forming a self-contained ecosystem and achieving a virtuous cycle of the food chain.

[0051] 5. The multi-source clean energy system used in this invention integrates tidal turbine generator sets, wave energy conversion devices, and photovoltaic power generation modules, providing stable power to various electromechanical equipment in the aquaculture tank around the clock, making deep and effective use of marine renewable energy, reducing dependence on traditional energy, and reducing pollution of the marine environment by traditional energy.

Here, the illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

[0076] This invention relates to a multifunctional aquaculture system for nearshore marine ranching, which is mainly designed to solve the problems in existing nearshore aquaculture technologies, such as the inability to cope with extreme weather, the decline in seawater quality caused by environmental pollution, and insufficient disaster early warning response.

[0077] The implementation of the present invention will be described in detail below with reference to preferred embodiments.

[0078] See the whole picture Figure 1 The shown block diagram and Figures 2 to 9The schematic diagram shown illustrates that this invention provides a multifunctional aquaculture system suitable for nearshore marine ranches. It mainly includes an aquaculture tank 1, a magnetic levitation power system 2, a buoyancy tank 3, an intelligent monitoring and control system 4, and a multi-source clean energy system 5. The aquaculture tank 1 serves as the main structure of the multifunctional aquaculture system, housing marine products for cultivation as needed. The magnetic levitation power system 2 provides the main frame of the aquaculture tank and simultaneously drives the tank 1 to levitate and rotate. This design reduces the entanglement and attachment of aquatic plants, preventing the farmed organisms from damaging the tank and escaping, while also significantly improving dissolved oxygen efficiency. The buoyancy tank 3 is a hollow structure that provides buoyancy to the aquaculture tank 1. The intelligent monitoring and control system 4 detects water quality and fluctuations in the surrounding waters and regulates the position of the aquaculture tank and the water quality conditions of the surrounding area. The multi-source clean energy system 5 provides power to the magnetic levitation power system 2 and the intelligent monitoring and control system 4.

[0079] In this embodiment, the aquaculture tank 1 is located in the sea, specifically in nearshore waters. It can float on the surface or be submerged below the surface. The aquaculture tank 1 has a cylindrical structure, such as... Figure 2 The cylindrical structure shown is designed to allow for continuous or intermittent rotation in seawater, with the interior serving as the aquaculture space.

[0080] The magnetic levitation power system 2 is located at both ends of the breeding box 1, supporting the breeding box 1 from both ends and providing the power for levitation and rotation. Specifically, as follows... Figure 3 , Figure 4 , Figure 5 As shown, the magnetic levitation power system 2 includes an inner ring component 21 and an outer ring component 22 arranged concentrically. The inner ring component 21 is connected to the breeding box 1 to support the breeding box 1. The outer ring component 22 is magnetically connected to the inner ring component 21 and is magnetically levitated and driven to rotate. The rotation of the inner ring component 21 drives the breeding box 1 to rotate. This can reduce the entanglement and attachment of aquatic plants and other plants, prevent the breeding objects from damaging the breeding box and escaping, and also significantly improve dissolved oxygen efficiency.

[0081] In one specific embodiment, such as Figure 4The inner ring assembly 21 includes an inner ring 211 and a central shaft 212, as well as an inner ring spoke connecting rod 213, an inner ring annular connecting rod 214, and an inner ring longitudinal connecting rod 215. The central shaft 212 and the inner ring 211 constitute a driving power structure. The inner ring 211 is installed at both ends of the central shaft 212, which passes through the center line of the breeding box 1. Under magnetic force, the inner ring 211 rotates with the central shaft 212. The inner ring spoke connecting rod 213 and the inner ring annular connecting rod 214... Together with the inner ring longitudinal connecting rod 215, they form the frame structure of the breeding box 1. Specifically, the inner ring radial connecting rod 213 is arranged radially, with the near end connected to the inner ring 211 and the far end connected to the inner ring annular connecting rod 214. The inner ring longitudinal connecting rod 215 is longitudinally connected, and the two ends are connected to two adjacent sets of inner ring annular connecting rods 214. The inner ring annular connecting rod 214 forms a ring, which matches the cylindrical shape of the breeding box 1. Under the rotation of the inner ring 211, the frame structure is driven to rotate.

[0082] In another specific embodiment, see also Figure 4 The outer ring assembly 22 includes an outer ring 221, an outer ring radial connecting rod 222, an outer ring annular connecting rod 223, and an outer ring longitudinal connecting rod 224. The outer ring 221 constitutes the driving power structure, and the outer ring radial connecting rod 222, the outer ring annular connecting rod 223, and the outer ring longitudinal connecting rod 224 together constitute the outer frame of the entire aquaculture system, supporting the aquaculture box 1 and the floating box 3. Specifically, the outer ring radial connecting rod 223 is radially connected between the outer ring 221 and the outer ring annular connecting rod 223. The shape of the outer ring annular connecting rod 223 matches the floating box 3 and is connected to the floating box 3 to support the floating box 3. The outer ring longitudinal connecting rod 224 is longitudinally connected between two adjacent sets of outer ring annular connecting rods 223.

[0083] As is easily understood, two sets of inner ring connecting rods 214 are set at both ends of the entire breeding box 1 to support it, while two or more sets of outer ring connecting rods 223 are set, which can be flexibly added in the middle according to the overall length of the entire breeding box 1. For example, one outer ring connecting rod 223 can be arranged at approximately 10m. Figure 2 The diagram shows that two sets of outer ring connecting rods 223 and two corresponding floats 3 are added to the middle of the breeding tank 1. The breeding tank 1 passes through the floats 3 but does not contact them. Instead, it is suspended by magnetic levitation provided by the inner ring components 21 and the outer ring components 22 at both ends.

[0084] Both the inner ring longitudinal connecting rod 215 and the outer ring longitudinal connecting rod 224 are set in multiple sets in the longitudinal direction, which are determined according to the load-bearing requirements of the breeding box 1. The inner ring longitudinal connecting rod 215 can correspond one-to-one with the outer ring longitudinal connecting rod 224, or be set more closely than the outer ring longitudinal connecting rod 224, so as to ensure the overall strength of the entire breeding box 1.

[0085] In addition, the inner longitudinal connecting rod 215 can be a continuous structure with the same length as the breeding tank 1. The outer longitudinal connecting rod 224 can also be a continuous structure when the breeding tank 1 is short. However, when the breeding tank 1 is long, an outer annular connecting rod 223 and a float 3 need to be added in the middle. In this case, the outer longitudinal connecting rod 224 is segmented, with each segment connecting to an adjacent outer annular connecting rod 223. Thus, two adjacent sets of outer annular connecting rods 223, the outer longitudinal connecting rods 224 between them, and the corresponding float 3 form a modular unit. Figure 6 As shown, it is prefabricated as a module, which is convenient and quick to assemble on site, and can be quickly disassembled and assembled according to the required size of the breeding box.

[0086] It should be noted that the connecting rods of the inner ring assembly 21 and the outer ring assembly 22 can be made of light steel and welded at the joints.

[0087] To ensure the smooth rotation of the breeding box 1, in one specific embodiment, the inner ring 211 is a rotor, which is a permanent magnet. The outer ring 221 contains winding coils. When the winding coils are energized, they generate magnetism, causing the rotor to levitate the central shaft 212. Simultaneously, adjusting parameters such as the number of turns and the coil current of the winding coils regulates the magnetic field strength and electromagnetic force. When the currents of multiple winding coils are unbalanced, torque is generated, driving the rotor and the central shaft to rotate, thereby rotating the breeding box 1. More specifically, multiple taps (terminals) are led out at different positions on the coil. The circuit can be connected to different taps, thus changing the effective number of turns connected to the circuit. For example, a 1000-turn coil has taps at 500 turns and 800 turns. When connected to the 500-turn tap, only 500 turns of the coil are connected to the circuit, generating a moderate electromagnetic force. When connected to the 800-turn tap, 800 turns of the coil are connected to the circuit, increasing the electromagnetic force. When connected to the end of the 1000-turn tap, all coils are active, generating the maximum electromagnetic force. The number of coil turns and the current are mutually restrictive; the more turns, the greater the resistance and the smaller the current, so they need to be considered together.

[0088] In a preferred embodiment, the outer ring 221 further includes a sensor, a controller, and a power amplifier. The sensor detects the rotor shaft center position and transmits a signal to the controller when the rotor deviates from the shaft center position. The controller's built-in program automatically adjusts the number of coil turns and the coil current, thereby adjusting the magnetic field strength and electromagnetic force in different directions until the rotor is located at the shaft center. The power amplifier can increase the magnetic force, further ensuring the normal operation of the inner ring assembly.

[0089] In one specific embodiment, the float 3 is an annular float ring, concentrically arranged outside the outer ring assembly 22, and connected and fixed to the outer ring annular connecting rod 223. Specifically, the outer ring annular connecting rod 223 and the float 3 are connected by a snap-fit ​​fastener. Specifically, multiple fasteners 31 are arranged on the float 3, and the fasteners 31 can be fixed to the float 3 by welding, bonding, or other methods, so that the outer ring annular connecting rod 223 can be easily fastened and fixed.

[0090] In one specific embodiment, such as Figure 2 , Figure 5 , Figure 6 As shown, the intelligent monitoring and control system 4 includes an air inlet / vent 41 at the top of the annular float and an air inlet / vent 42 at the bottom. The system uses monitoring data to regulate the air and water content inside the annular float, thereby fine-tuning the floating depth of the aquaculture tank 1 in seawater. Specifically, the intelligent monitoring and control system uses monitoring data to inflate and de-inflate the float 3, regulating the water inlet and outlet, thus adjusting the floating depth of the aquaculture tank 1 to ensure it rises and falls to a suitable aquaculture depth.

[0091] In a preferred embodiment, the intelligent monitoring and control system 4 further includes an impact warning unit 44 and a float box lifting limit device 43. The impact warning unit 44 is disposed at multiple locations in the breeding box 1 to detect the impact that the breeding box 1 will be subjected to. The float box lifting limit device 43 is disposed at least at both ends of the breeding box 1 and is slidably connected to the float box 3 to reduce the floating depth of the breeding box 1 when an impact is detected to be coming or about to come, thereby reducing the impact of the impact on the breeding box 1.

[0092] Collision warning units 44 are distributed on the cylindrical body of the breeding tank 1, providing multi-point monitoring, such as by attaching them to the ends, middle of the side walls, and bottom of the cylindrical body. Figure 2 As shown, a multi-point detection network is formed. Specifically, the collision warning unit 44 is composed of a pressure sensor, an acceleration sensor, an ultrasonic sensor, an infrared sensor, and an alarm. The pressure sensor monitors changes in water pressure to determine if there is a collision; the acceleration sensor detects vibration or impact of the tank; the ultrasonic sensor detects obstacles through sound wave reflection; the infrared sensor detects approaching objects using infrared light; and the alarm sounds when the collision sensor detects an impact, alerting the user. To ensure the proper functioning of the sensors, a bio-adhesive coating (such as a silicone-based coating) is applied to the sensor surface, which is cleaned regularly.

[0093] See also Figure 7 , Figure 8 , Figure 9The floating box lifting and limiting device 43 includes a floating box chute 431, an anchor chain 432, and a counterweight anchor 433. The floating box chute 431 can be made of channel steel, fixed to the seabed, and connected to both sides of the floating box 3 through the chute, allowing the floating box 3 to slide up and down within the chute. The counterweight anchor 433 has a wheel and is placed on the seabed. The anchor chain 432 is laid in the chute, with one end connected to the floating box 3 and the other end connected to the counterweight anchor 433 on the seabed. When the floating box 3 needs to be lowered or raised, the length of the anchor chain 432 is adjusted to keep the floating box 3 in a balanced state at the corresponding height and limit its movement. When seawater or large alien organisms cause impact, an alarm is triggered. By using the floating box chute 431 and the anchor chain 432 in conjunction, the depth of the entire aquaculture tank 1 is adjusted so that it enters deep water before a storm, thereby effectively avoiding the impact of severe sea conditions and extreme weather such as typhoons, or avoiding the impact of large organisms, reducing unnecessary losses.

[0094] In this embodiment, the length of the anchor chain 432 can be adjusted manually by combining a wheel and a handle, with the anchor chain 432 wound around the wheel of the counterweight anchor 433. Alternatively, it can be adjusted electrically to control the automatic rotation of the wheel.

[0095] The intelligent monitoring and control system 4 also includes a water quality monitoring unit and a water quality intelligent control unit. The water quality monitoring unit includes temperature sensors, pH monitors, water level monitors, etc., which are fixed on the longitudinal connecting rods at the top, middle and bottom of the outer ring. It is used to monitor water temperature, dissolved oxygen, pH, salinity, turbidity, water level and other water environment indicators in real time. The water quality intelligent control unit includes an aerator, a water exchange pump, etc. It automatically starts when the water environment indicators exceed the threshold. It dynamically controls the water quality parameters inside the breeding tank through precise detection.

[0096] In this invention, the multifunctional aquaculture system also includes an ecological purification system, installed on the aquaculture tank 1 and in the waters near the tank 1, to purify the wastewater generated by the tank 1 and prevent pollution. This system comprises three parts: a degradation device, an absorption device, and a control device. These three components work together to purify the wastewater generated by aquaculture, preventing pollution of seawater. The degradation device is a primary purification biodegradation system, degrading ammonia nitrogen and nitrite through nitrification / denitrification. Specifically, it involves arranging suspended boxes on longitudinal connecting rods, annular connecting rods, and radial connecting rods. The suspended boxes are filled with porous materials (such as polyethylene suspended balls or volcanic rock) and a compound bacterial agent (nitrifying bacteria, Bacillus, etc.) is added. The absorption device is a secondary purification plant absorption system, utilizing the unique properties of aquatic plants to absorb nitrates and phosphates, improving the aquatic environment and releasing oxygen. Examples of suitable plants include large algae (Gracilaria, Gracilaria, etc.) and floating plants (Ipomoea, Water Hyacinth, etc.). Specifically, it involves... Floating planting platforms are placed in the waters near the aquaculture tanks, maintaining a certain distance to prevent plants from entangled in the tanks. These platforms require regular harvesting to control their growth. The control system is a three-stage purification animal control system, primarily designed to remove organic debris and control excessive algae growth. Specifically, filter-feeding shellfish (such as oysters or scallops) are suspended in the mid-water layer. These shellfish obtain food by filtering suspended particles (such as silt, organic debris, and plankton) from the seawater. Simultaneously, fish that feed on suspended organic matter (such as tilapia) are introduced. This ecological purification system achieves in-situ purification of aquaculture wastewater, reducing pollution to external waters. It also allows for the harvesting of algae and shellfish, generating additional revenue and forming a "fish-shellfish-algae-bacteria" symbiotic system, creating a closed-loop food chain and a sustainable circular system. By combining multiple systems, the position of the aquaculture tank in the seawater and the water quality inside the tank can be automatically adjusted according to changes in seawater quality or the dynamics of the seawater. It can also purify the wastewater generated by the aquaculture tank. This can not only greatly improve the profitability of nearshore aquaculture, but also avoid pollution to the ocean, thus achieving both economic benefits and environmental protection.

[0097] This embodiment provides a multi-source clean energy system for power supply. The multi-source clean energy system includes an integrated tidal turbine generator set, a wave energy conversion device, and a photovoltaic power generation module. It can be implemented by using existing tidal turbine generator sets and adding photovoltaic modules. Through a composite energy storage system, it provides continuous power supply and storage for the system equipment around the clock. This system is a clean energy source that makes deep and effective use of marine renewable energy, which can greatly reduce resource consumption and reduce pollution to the marine environment.

[0098] In this embodiment, the size of the mesh openings on the breeding box can be determined comprehensively based on the body size, growth stage, water flow conditions, and escape prevention and harm prevention requirements of the target breeding species.

[0099] The high salinity, humidity, and microorganisms of the marine environment accelerate metal corrosion, necessitating anti-corrosion treatment. In this embodiment, the multi-functional aquaculture system is constructed entirely of hot-dip galvanized steel, coated with an anti-corrosion paint to form a protective layer. Aluminum alloy anodes are installed on key corrosion-prone areas, evenly distributed to cover all metal components requiring protection. Furthermore, due to the presence of organisms within the aquaculture tanks, environmentally friendly anti-corrosion materials are selected to avoid toxicity to the organisms. Regularly inspecting corrosion, coating condition, and anode consumption, and performing timely maintenance, can extend the equipment's lifespan.

[0100] To further enhance understanding of this embodiment, the working principle of the multifunctional aquaculture system includes:

[0101] First, the aquaculture tank is fixed to the inner frame, powered by a multi-source clean energy system. Then, the winding coil is energized to generate magnetism, which drives the rotor to suspend and rotate the tank. Simultaneously, impact sensors, temperature sensors, pH detectors, water level detectors, aerators, and water pumps operate. These sensors send data to an intelligent monitoring and control system. After analysis, the system monitors the water conditions near the tank in real time, controlling the water level in the buoy and adjusting its position, which in turn adjusts the tank to the optimal aquaculture depth – this is a small, gradual adjustment. Simultaneously, it monitors the activity of large organisms around the tank. If extreme weather events such as typhoons or large organisms are detected, an alarm is triggered, and the counterweight anchor's wheel rotates, shortening the anchor chain and rapidly lowering the tank to a safe depth – this is a large, rapid adjustment. Furthermore, if water quality indicators exceed thresholds, the aerator and water pump are activated, achieving dynamic control of water quality parameters through precise detection.

[0102] In summary, the multifunctional aquaculture system provided by this invention can achieve at least the following objectives:

[0103] 1. This invention applies a magnetic levitation system to marine aquaculture. By coordinating the winding coil and the rotor, the aquaculture tank is driven to rotate continuously at a low speed through magnetic levitation power. On the one hand, this can reduce the entanglement and attachment of aquatic plants and other plants, preventing the aquatic organisms from breaking through the net and escaping. On the other hand, it can also improve dissolved oxygen efficiency.

[0104] 2. This invention combines a magnetic levitation system with a breeding box. The breeding box provides basic breeding functions while being integrated with the magnetic levitation power system (mainly manifested in the integration of the breeding box and the inner ring components). The magnetic levitation power system not only provides driving force but also serves as the main structure of the breeding facility to some extent. There is no need to set up additional breeding facilities or driving systems. The structure is simple, compact, and easy to implement.

[0105] 3. By setting up impact sensor equipment and floating box lifting equipment, this invention can be used to issue alarm prompts for impacts from seawater and large alien organisms, and adjust the position of the aquaculture box, which can effectively avoid damage to the aquaculture box caused by severe sea conditions, typhoons and other extreme weather, and large alien organisms, thereby improving economic efficiency.

[0106] 4. This invention operates by setting up a temperature sensor, pH detector, water level detector, aerator, and water exchange pump, which can accurately detect and dynamically regulate water quality parameters, thereby improving aquaculture efficiency.

[0107] 5. This invention constructs a composite energy storage system by using an integrated tidal turbine generator set, wave energy conversion device and photovoltaic power generation module to provide continuous power for the operation of a multi-functional aquaculture system around the clock, realize the utilization of clean energy and reduce waste;

[0108] 6. By constructing a "fish-shellfish-algae-bacteria" co-culture system, this invention can not only achieve in-situ purification of aquaculture wastewater and reduce pollution to external waters, but also generate additional revenue by harvesting algae, shellfish and other organisms, thereby improving economic efficiency.

[0109] The various embodiments of the present invention have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
