Description

Technical Field

[0001] This invention belongs to the field of marine engineering equipment technology, and in particular relates to an aquaculture-data fusion platform based on wind power and its control method. Background Technology

[0002] Deep-sea aquaculture platforms need to be deployed long-term in areas far from shore, with complex sea conditions and high maintenance costs. Traditional aquaculture platforms mostly rely on shore-based power supply, diesel generators, or independent energy systems, resulting in high energy replenishment and operation and maintenance costs. With the development of floating offshore wind power into deep-sea areas, placing wind power generation units and aquaculture equipment on the same offshore platform can provide continuous energy for aquaculture monitoring, feeding, oxygenation, communication, and equipment maintenance.

[0003] Existing wind power and aquaculture integration solutions mostly involve physical layout within the same area or platform, lacking a clear energy and information loop between wind power, aquaculture, and data processing. Fixed-depth aquaculture cages are subjected to significant wave loads under typhoon, strong wave, and large platform movements, making them prone to netting damage, frame deformation, and fish stress. Some liftable cages use winches, steel cables, or ballast adjustment methods to achieve depth changes, but their guiding constraints are insufficient, and their response speed, positioning accuracy, failure locking, and long-term anti-jamming capabilities are insufficient to meet the operation and maintenance requirements of deep-sea platforms. Summary of the Invention

[0004] The purpose of this invention is to provide a wind power-based aquaculture-data fusion platform and its control method to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following solution: A wind power-based aquaculture-data fusion platform includes: an SPAR-type floating foundation, a wind power generation unit installed on the top of the SPAR-type floating foundation, a liftable rigid aquaculture cage circumferentially installed on the main column of the SPAR-type floating foundation, a guide mechanism between the liftable rigid aquaculture cage and the main column, the main column being moored to the seabed by a mooring system, and a data equipment compartment for collecting water quality, fish behavior and equipment status data, as well as an energy storage and control system for receiving electrical energy output from the wind power generation unit and supplying power to the guide mechanism and the data equipment compartment, and outputting control commands. A hydraulic drive system and a locking device are provided between the main column and the liftable rigid aquaculture cage. The hydraulic drive system drives the liftable rigid aquaculture cage to switch between normal aquaculture position, maintenance and repair position and typhoon resistance and disaster avoidance position. The guiding mechanism includes a vertical guide rail fixed to the outside of the main column and extending vertically. A guide unit group is slidably connected to the vertical guide rail. A replaceable composite gasket is detachably connected between the vertical guide rail and the guide unit group. The replaceable composite gasket is in sliding contact with the vertical guide rail.

[0006] This invention comprises an SPAR-type floating foundation, a wind power generation unit, a liftable rigid aquaculture cage, a guiding mechanism, a mooring system, a data equipment compartment, and an energy storage and control system. In operation, the wind power generation unit generates electricity and stores it in the energy storage and control system, powering the hydraulic drive system and the data equipment compartment. The data equipment compartment collects water quality, fish behavior, and equipment status data. The hydraulic drive system drives the cage to rise and fall along vertical guide rails, switching between three positions: normal aquaculture, maintenance and repair, and typhoon preparedness. A locking device locks the cage at the target position. In the guiding mechanism, the vertical guide rails are fixed to the outside of the main column, and the guiding unit assembly slides with the guide rails. A replaceable composite liner is placed between the two and slides in contact. This solution integrates energy self-sufficiency, controllable cage lifting and lowering, reliable guidance, and data acquisition, reducing the risk of jamming and interference.

[0007] Preferably, the guide unit group is provided with a scraper, which is disposed at the top and / or bottom of the guide unit group. The scraper slides in contact with the vertical guide rail and is used to remove the adhering substances on the surface of the vertical guide rail.

[0008] A scraper is installed on the guide unit assembly, located at the top and / or bottom of the assembly, and slides in contact with the vertical guide rail. During use, the scraper simultaneously removes soft deposits (such as marine organisms and silt) from the surface of the vertical guide rail during the raising and lowering of the net cage, preventing these deposits from entering the guide gap and causing jamming or increased wear. This improves the self-cleaning capability and maintenance cycle of the guide mechanism in long-term marine environments.

[0009] Preferably, a flushing port is provided on one side of the guide unit group, the flushing port is connected to the inner cavity of the guide unit group, and a drain port is provided at the bottom of the guide unit group, the drain port is connected to the inner cavity of the guide unit group, and the flushing port is used to connect to an external high-pressure water source.

[0010] A flushing port (connecting to the inner cavity) is located on one side of the guide unit assembly, and a drain port is located at the bottom. During use, when deep cleaning is required, an external high-pressure water source is injected into the inner cavity of the guide unit assembly through the flushing port to wash away accumulated mud, shellfish fragments, and other attachments. Wastewater and debris are discharged from the drain port. This structure prevents the formation of a closed, sludge-accumulating cavity inside the guide unit, further improving the maintainability and reliability of the guide mechanism.

[0011] Preferably, the hydraulic drive system is provided with multiple sets, and the hydraulic drive system includes hydraulic cylinders. One end of the hydraulic cylinder is connected to the main column, and the other end of the hydraulic cylinder is connected to the frame of the liftable rigid aquaculture cage. The hydraulic cylinder is connected to a hydraulic pump station through hydraulic pipelines, and control valve groups, accumulators, pressure sensors and displacement sensors are provided on the hydraulic pipelines.

[0012] The hydraulic drive system consists of multiple components, including hydraulic cylinders, a hydraulic pump station, hydraulic lines, a control valve assembly, an accumulator, pressure sensors, and displacement sensors. During operation, the hydraulic pump station supplies pressurized oil, and the control valve assembly synchronously controls the extension and retraction of each hydraulic cylinder based on feedback signals from the pressure and displacement sensors. The accumulator is used to supplement peak flow or absorb shocks. This hydraulic system enables smooth and synchronous lifting and lowering of the cage, and monitors hydraulic pressure and displacement in real time to prevent jamming caused by uneven loading or asynchrony.

[0013] Preferably, the guide unit group includes a main guiding unit and an auxiliary limiting unit. The main guiding unit slides with the vertical guide rail. The main guiding unit is used to bear the main radial load and vertical friction force. The auxiliary limiting unit is used to limit the circumferential rotation and eccentric overturning of the liftable rigid aquaculture cage relative to the main column.

[0014] The guide unit assembly includes a main directional unit and an auxiliary limiting unit. In use, the main directional unit bears the primary radial load (such as lateral forces caused by waves) and vertical friction (lifting resistance); the auxiliary limiting unit restricts the circumferential rotation and eccentric overturning of the gabion relative to the main column. This combination ensures the gabion's stable posture during lifting and static positions, preventing guide rail wear or locking failure due to rotation or tilting.

[0015] Preferably, the replaceable composite liner is made of a seawater-resistant composite material, and the coefficient of friction of the replaceable composite liner is ≤0.15.

[0016] The replaceable composite gasket is made of seawater-resistant composite material with a friction coefficient ≤0.15. During use, the gasket slides in contact with the vertical guide rail. The low friction coefficient reduces the load and energy consumption of the hydraulic drive system. Its seawater-resistant properties make it suitable for long-term underwater environments. The replaceable design allows for easy replacement of the gasket at the maintenance station after wear, extending the overall lifespan of the guide mechanism.

[0017] Preferably, the data equipment compartment includes multiple segmented annular compartments distributed circumferentially around the main column, and a mooring avoidance corridor is provided at a position corresponding to the main direction of the mooring system. The mooring avoidance corridor is used to avoid the mooring lines, guides or mooring accessories of the mooring system.

[0018] The data equipment compartment comprises multiple segmented annular compartments distributed circumferentially around the main column, with mooring avoidance corridors located at positions corresponding to the main direction of the mooring system. In use, these corridors provide passage or avoidance space for mooring lines, guide wires, or mooring accessories, preventing physical interference between the data equipment compartment and the mooring system. Simultaneously, they maintain the continuous monitoring capability of the data equipment compartment around the main column, achieving an integrated and coordinated arrangement between the underwater equipment compartment and the mooring system.

[0019] Preferably, the data equipment compartment includes a sealed pressure chamber, a water quality sensor, a communication unit, and an underwater camera. The water quality sensor is used to acquire data on dissolved oxygen, temperature, salinity, pH, turbidity, and ammonia nitrogen in the water. The underwater camera acquires images of fish density, feeding behavior, abnormal behavior, and net status. The communication unit is used to transmit the information acquired by the water quality sensor and the underwater camera to the energy storage and control system.

[0020] The data equipment compartment includes a sealed pressure chamber, water quality sensors, a communication unit, and an underwater camera. In operation, the water quality sensors acquire real-time data on dissolved oxygen, temperature, salinity, pH, turbidity, and ammonia nitrogen; the underwater camera captures images of fish density, feeding behavior, abnormal behavior, and netting conditions; and the communication unit transmits this information to the energy storage and control system. This configuration provides a real-time, multi-dimensional data foundation for aquaculture decision-making and environmental monitoring.

[0021] Preferably, the energy storage and control system includes a control unit, an energy storage unit, and an edge computing unit. The edge computing unit calculates and outputs control commands to the control unit based on the information obtained by the water quality sensor and the underwater camera. The energy storage unit is used to store the electrical energy generated by the wind power generation unit and supply power to the data equipment compartment and the hydraulic pump station.

[0022] The energy storage and control system comprises a control unit, an energy storage unit, and an edge computing unit. In operation, the energy storage unit stores the electrical energy generated by the wind turbine and supplies power to the data equipment cabin and hydraulic pump station. The edge computing unit performs calculations based on information acquired by sensors and cameras and outputs control commands (such as feeding, oxygenation, maintenance warnings, or workstation switching) to the control unit. This structure enables on-site wind energy consumption, local data processing, and automated closed-loop control, reducing reliance on shore-based communication and remote operation.

[0023] A control method for a wind power-based aquaculture-data fusion platform, comprising the following steps: The energy storage and control system receives electrical energy from the wind power generation unit and supplies power to the data equipment compartment and hydraulic pump station. The data equipment compartment collects water quality data, images of fish behavior, and equipment status data, and transmits them to the energy storage and control system. The energy storage and control system is also used to receive typhoon or severe sea state warnings and to determine whether preset maintenance and repair conditions have been met based on the comparison of collected data with preset thresholds. When maintenance and repair conditions are met, the energy storage and control system controls the hydraulic drive system to switch the liftable rigid aquaculture cage to the maintenance and repair position and activates the locking device to lock it; after maintenance is completed, the locking is released and it returns to the normal aquaculture position. When a typhoon or severe sea state warning is received, the energy storage and control system controls the hydraulic drive system to switch the liftable rigid aquaculture cage to a typhoon-resistant and disaster-avoidance position and activates the locking device to lock it; after the severe sea state ends, the locking is released after a safety inspection and the cage is restored to its normal aquaculture position.

[0024] Compared with the prior art, the present invention has the following advantages and technical effects: This invention integrates a wind power generation unit, energy storage and control system, data equipment compartment, and hydraulically driven liftable net cage into an SPAR-type floating foundation, forming an energy and information closed loop between wind power supply, data acquisition, edge computing, and aquaculture execution. This solves the problem of isolation between wind power, aquaculture, and data processing in existing solutions. The hydraulic drive system moves the net cage along vertical guide rails, switching between normal aquaculture positions, maintenance and repair positions, and typhoon-resistant positions, with a locking device ensuring reliable positioning. Compared to winch and cable solutions, this significantly improves lifting response speed and positioning accuracy, reducing the risk of net damage, frame deformation, and fish stress in strong sea conditions. The vertical guide rails, guide unit groups, and replaceable composite pads in the guiding mechanism provide clear guiding constraints and a low-friction sliding path. Combined with scraping, flushing, and sewage discharge structures, and the replaceable pad design, this effectively solves the problems of jamming, uneven wear, and insufficient maintenance accessibility in long-term marine environments.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Reference Figures 1 to 8 This invention discloses a wind power-based aquaculture-data fusion platform, comprising: a SPAR-type floating foundation 1, a wind power generation unit 2 installed on the top of the SPAR-type floating foundation 1, a liftable rigid aquaculture cage 3 circumferentially installed on the main column 11 of the SPAR-type floating foundation 1, a guide mechanism 4 between the liftable rigid aquaculture cage 3 and the main column 11, the main column 11 being moored to the seabed by a mooring system 7, and a data equipment compartment 5 for collecting water quality, fish behavior and equipment status data, and an energy storage and control system 6 for receiving electrical energy output from the wind power generation unit and supplying power to the guide mechanism 4 and the data equipment compartment 5, as well as outputting control commands. The main column 11 is provided with a ballast area 12 and a mooring connection area 13. The main function of the ballast area 12 is to lower the center of gravity of the entire platform and increase the draft of the platform by filling it with ballast water or solid ballast material, thereby improving the stability and anti-overturning ability of the SPAR type floating foundation 1 in the deep sea environment.

[0029] A hydraulic drive system 44 and a locking device 45 are provided between the main column 11 and the liftable rigid aquaculture cage 3. The hydraulic drive system 44 drives the liftable rigid aquaculture cage 3 to switch between the normal aquaculture position, the maintenance and repair position and the typhoon resistance and disaster avoidance position. The locking device 45 employs a mechanical locking pin, a rack and pinion locking mechanism, a hydraulic lock, a balance valve, a pawl mechanism, or a combination thereof. Specifically, the locking device 45 includes two levels of redundancy: hydraulic circuit self-locking and mechanical locking. When the liftable rigid aquaculture cage 3 is in a maintenance or typhoon-resistant position, the locking device 45 activates to prevent unauthorized slippage of the liftable rigid aquaculture cage 3 caused by hydraulic pressure loss, platform movement, or wave impact.

[0030] The guide mechanism 4 includes a vertical guide rail 41 fixed to the outside of the main column 11 and extending vertically. A guide unit group 42 is slidably connected to the vertical guide rail 41. A replaceable composite gasket 43 is detachably connected between the vertical guide rail 41 and the guide unit group 42. The replaceable composite gasket 43 is in sliding contact with the vertical guide rail 41.

[0031] The replaceable composite liner 43 is made of a composite material with a friction coefficient of no more than 0.15 and is resistant to seawater corrosion. The thickness of the replaceable composite liner 43 is 20-50mm, preferably 30mm. The replaceable composite liner 43 is fixed to the inside of the main directional unit 421 housing by bolts, pressure plates, dovetail grooves, quick clips, or locking devices that can be operated by an underwater robot. During maintenance, the liftable rigid aquaculture cage 3 can be switched to the maintenance and repair position, bringing the main directional unit 421 close to the water surface, where the old liner can be removed manually or by an underwater robot and a new liner can be installed.

[0032] The number of vertical guide rails 41 is at least 6. The number of guide rails N can be determined based on the total equivalent load of the cage, the maximum lateral acceleration of the platform, the allowable stress of the guide rails, and the effective bearing area of ​​the guide rails. The engineering verification formula for the number of guide rails N is: ,in This represents the equivalent wet weight of the net cage and the equivalent load of the fish school. The maximum lateral acceleration of the platform, For the allowable stress of the guide rail material, The effective bearing area of ​​a single guide rail. The vertical guide rail 41 can be made of seawater corrosion resistant material or wear-resistant steel, and can be equipped with ceramic coating, laser cladding layer, wear-resistant composite layer or anti-fouling coating.

[0033] In a further optimized design, a scraper 46 is provided on the guide unit group 42. The scraper 46 is located at the top and / or bottom of the guide unit group 42. The scraper 46 slides in contact with the vertical guide rail 41 and is used to remove the adhering substances from the surface of the vertical guide rail 41.

[0034] The scraper 46 is used to remove soft deposits from the surface of the vertical guide rail 41 during the lifting and lowering of the liftable rigid aquaculture cage 3.

[0035] In a further optimized design, a flushing port 47 is provided on one side of the guide unit group 42, which is connected to the inner cavity of the guide unit group 42. A drain port 48 is provided at the bottom of the guide unit group 42, which is connected to the inner cavity of the guide unit group 42. The flushing port 47 is used to connect to an external high-pressure water source.

[0036] The drain outlet 48 is used to discharge mud, shellfish fragments and attached substances from the guide unit group 42 to avoid the formation of a closed sludge accumulation cavity.

[0037] To further optimize the scheme, the hydraulic drive system 44 is equipped with multiple sets. The hydraulic drive system 44 includes a hydraulic cylinder 441. One end of the hydraulic cylinder 441 is connected to the main column 11, and the other end of the hydraulic cylinder 441 is connected to the frame of the liftable rigid aquaculture cage 3. The hydraulic cylinder 441 is connected to the hydraulic pump station 442 through the hydraulic pipeline 443. The hydraulic pipeline 443 is equipped with a control valve group 444, an accumulator 445, a pressure sensor 446, and a displacement sensor 447.

[0038] The hydraulic drive system 44 is equipped with at least three sets. The energy storage and control system 6 performs synchronous control based on the displacement and pressure feedback of each hydraulic cylinder 441 to reduce the risk of jamming caused by eccentric lifting. The stroke of the hydraulic cylinder 441 is 30%-50% of the total height of the liftable rigid aquaculture cage 3, and is ultimately determined based on the maintenance lifting amount, anti-striking submersion amount, and safety margin.

[0039] The thrust of the hydraulic cylinder is determined by the following formula: Where W_wet is the equivalent wet weight of the height-adjustable rigid aquaculture cage 3. The inertial force caused by the added mass, The vertical component of the wave-current load. To guide frictional resistance, The number of hydraulic cylinders is 441. For safety reasons, for open-type wire mesh cages, The weight of all seawater within the cage should not be taken simply. Instead, it should be determined comprehensively based on the cage's own weight, buoyancy, the load of aquaculture organisms, additional mass, and the actual moving water body.

[0040] The scheme is further optimized. The guide unit group 42 includes a main guiding unit 421 and an auxiliary limiting unit 422. The main guiding unit 421 slides with the vertical guide rail 41. The main guiding unit 421 is used to bear the main radial load and vertical friction force. The auxiliary limiting unit 422 is used to limit the circumferential rotation and eccentric overturning of the liftable rigid aquaculture cage 3 relative to the main column 11.

[0041] A 10-30mm running gap is reserved between the main guiding unit 421 and the vertical guide rail 41 to take into account the smoothness of sliding, manufacturing and installation errors, marine organism attachment tolerance and collision safety margin.

[0042] Further optimization of the design: the material of the replaceable composite gasket 43 includes a seawater corrosion-resistant composite material, and the coefficient of friction of the replaceable composite gasket 43 is ≤0.15.

[0043] The data equipment compartment 5 is further optimized by including multiple segmented annular compartments that are distributed around the main column 11 in a circumferential manner. A mooring avoidance corridor 51 is set at a position corresponding to the main direction of the mooring system 7. The mooring avoidance corridor 51 is used to avoid the mooring lines, guide wires or mooring accessories of the mooring system 7.

[0044] The scheme has been further optimized. The data equipment compartment 5 includes a sealed pressure chamber, a water quality sensor, a communication unit, and an underwater camera. The water quality sensor is used to acquire data on dissolved oxygen, temperature, salinity, pH, turbidity, and ammonia nitrogen in the water. The underwater camera acquires images of fish density, feeding behavior, abnormal behavior, and net status. The communication unit is used to transmit the information acquired by the water quality sensor and the underwater camera to the energy storage and control system 6.

[0045] The data equipment compartment 5 adopts a segmented annular structure. Each segment includes a sealed pressure chamber, water quality sensors, underwater cameras, communication units, heat exchange units, and watertight connectors. The segmented annular structure has reserved mooring avoidance corridors at positions corresponding to the main direction of the mooring system 7 to avoid spatial interference with mooring lines, guide wires, or mooring accessories. When the platform uses three-point mooring, the mooring avoidance corridor 51 is set according to the actual main directions of the three mooring lines; when the platform uses other mooring methods, the mooring avoidance corridor 51 is set according to the actual envelope of the mooring lines.

[0046] The scheme is further optimized. The energy storage and control system 6 includes a control unit, an energy storage unit and an edge computing unit. The edge computing unit calculates based on the information obtained by the water quality sensor and the underwater camera and outputs control commands to the control unit. The energy storage unit is used to store the electrical energy generated by the wind power generation unit 2 and supply power to the data equipment cabin 5 and the hydraulic pump station 442.

[0047] A control method for a wind power-based aquaculture-data fusion platform, comprising the following steps: The energy storage and control system 6 receives electrical energy output from the wind power generation unit 2 and supplies power to the data equipment compartment 5 and the hydraulic pump station 442; Data equipment compartment 5 collects water quality data, images of fish behavior, and equipment status data, and transmits them to the energy storage and control system 6; The energy storage and control system 6 is also used to receive typhoon or severe sea state warnings and to determine whether preset maintenance and repair conditions have been met based on the comparison of collected data with preset thresholds. When maintenance and repair conditions are met, the energy storage and control system 6 controls the hydraulic drive system 44 to switch the liftable rigid aquaculture cage 3 to the maintenance and repair position and activates the locking device 45 to lock it; after maintenance is completed, the locking is released and it returns to the normal aquaculture position. When a typhoon or severe sea state warning is received, the energy storage and control system 6 controls the hydraulic drive system 44 to switch the liftable rigid aquaculture cage 3 to the typhoon-resistant and disaster-avoidance position, and activates the locking device 45 to lock it; after the severe sea state ends, the locking is released after a safety inspection and the cage is restored to the normal aquaculture position.

[0048] The energy storage and control system 6 receives electrical energy from the wind power generation unit 2 and supplies power to the hydraulic pump station 442, data equipment compartment 5, sensors, feeder, aerator, and communication equipment. Water quality sensors collect data on dissolved oxygen, temperature, salinity, pH, turbidity, and ammonia nitrogen; underwater cameras collect images of fish density, feeding behavior, abnormal behavior, and net status; the guide mechanism collects hydraulic pressure, displacement, guide clearance, liner wear, and locking status. The edge computing unit processes the above data and outputs commands for feeding, aeration, water quality control, maintenance, and workstation switching.

[0049] The present invention has at least the following beneficial effects: First, the controlled lifting and lowering of the liftable rigid aquaculture cage 3 is achieved through the hydraulic drive system 44 and at least six vertical guide rails 41, enabling the liftable rigid aquaculture cage 3 to switch between normal aquaculture, maintenance and repair, and typhoon avoidance positions; the hydraulic drive response time can be designed to be 3-8 minutes, which is about 10 times faster than the 30-60 minute lifting and lowering response time of winches and steel cables. Second, a clear load transmission path is formed through the main guiding unit 421, the auxiliary limiting unit 422, and the replaceable composite liner 43 with a friction coefficient of no more than 0.15, achieving a positioning accuracy of ±50mm, reducing the risks of jamming, eccentricity, torsion, and collision during the lifting and lowering process. Third, the maintenance accessibility of the guiding mechanism 4 in long-term marine environments is improved through the scraper 46, flushing port 47, sewage outlet 48, and replaceable composite liner 43, reducing maintenance costs by about 70% compared to solutions that require towing back to port or large-scale underwater disassembly and assembly. Fourth, the data equipment compartment 5 and mooring avoidance corridor 51 reduce the risk of interference between underwater equipment and the mooring system. Fifth, a closed loop of energy and information is formed through wind power supply, edge computing, aquaculture execution, and status feedback. Sixth, through typhoon-resistant shelter positions, position locking, and oxygenation maintenance, the platform's structural safety and fish survival conditions are balanced under strong sea conditions, and the fish survival rate target during typhoon resistance can be designed to be greater than 95%.

[0050] Compared to fixed-depth net cages, this invention can switch the liftable rigid aquaculture net cage 3 to a typhoon-resistant and disaster-avoidance position via a hydraulic drive system, and restrict unauthorized sliding of the net cage through a locking device 45, thereby reducing the risk of structural damage and fish stress under extreme sea conditions. Compared to winch cable drive schemes, this invention uses direct hydraulic cylinder drive and is equipped with vertical guide rails 41, guide unit groups 42, and replaceable composite pads 43, which can improve response speed, positioning accuracy, and locking reliability. Compared to independent underwater equipment compartments, this invention sets the data equipment compartment 5 as a segmented annular compartment and reserves a mooring avoidance corridor 51 in the main direction of the mooring system 7, so that the data equipment compartment 5 is arranged in a coordinated manner with the platform body, mooring system 7, and liftable rigid aquaculture net cage 3.

[0051] Maintenance and repair methods: When the monitoring results of the guide mechanism 4, hydraulic drive system 44, and netting or data equipment compartment 5 reach the preset maintenance conditions, the energy storage and control system 6 calls the maintenance judgment function. A comprehensive assessment is made of the necessity of maintenance and the accessibility of the maintenance window. If The system outputs a maintenance permission command, and the energy storage and control system 6 controls the hydraulic drive system 44 to switch the net cage 3 to the maintenance and repair position and activate the locking device 45. After locking, manual or underwater robot operations are performed, including replacing the composite liner 43, cleaning the guide rails, repairing the netting, replacing sensors, or maintaining the data equipment compartment. After maintenance is completed and verified, the locking is released and the net cage 3 is restored to its normal aquaculture position.

[0052] Maintenance and repair judgment function It can be represented as: = · / + · / + · / + · / + · / + · ,in This represents the wear amount of the composite gasket. For guide clearance, For hydraulic cylinder pressure deviation, This refers to the hydraulic leakage rate. The area or level of damage to the mesh fabric. This is a sign of an abnormal seal in the data equipment compartment. to For weighting coefficients. When Greater than the maintenance threshold When the effective wave height, wind speed, flow velocity, and platform motion response all meet the maintenance window requirements, the maintenance and repair workstation switch is executed; when Greater than However, risk aversion judgment and descent depth control function When the output risk level is high, the system prioritizes maintaining or submerging to the typhoon-resistant risk-avoidance position and transfers the maintenance task to the queue to be executed after the typhoon or strong sea state.

[0053] Typhoon preparedness and disaster avoidance methods: Upon receiving a typhoon or severe sea state warning, the energy storage and control system 6 first performs a system check to confirm that the hydraulic drive system 44, locking device 45, energy storage unit, oxygenation equipment, communication equipment, guiding mechanism 4, and data equipment compartment 5 are in an executable risk avoidance state; then it calls the risk avoidance judgment and descent depth control function. The decision to enter the descent avoidance mode and the target descent depth are determined based on the effective wave height, wave period, wind speed, flow velocity, platform motion response, hydraulic stroke, and cage status.

[0054] This includes a risk assessment subfunction and a depth control subfunction. The risk assessment subfunction collects the effective wave height. Wave period Wind speed Flow rate Platform motion response The relative displacement between the main column 11 and the cage 3 44 Remaining stroke of hydraulic drive system Locking device 45 state Energy storage status Dissolved oxygen in water Fish density Equipment health coefficient Typhoon warning signs And calculate the risk aversion index. .when Reaching the first trigger threshold At that time, the system enters a pre-descent risk avoidance mode; when Reaching the second trigger threshold If any parameter among the measured effective wave height, platform motion response, or relative displacement exceeds the emergency threshold, the system enters an immediate descent avoidance mode.

[0055] The depth control sub-function outputs the target descent depth based on the risk level. In one implementation, = [ + · (0, - )+ · (0, - )+ · (0, - )+ · (0, - ), , ],in Based on the depth of the dive, To minimize the risk of diving, To allow the maximum diving depth, to For adjustment coefficients, This represents the amplitude limiting function. The minimum value among the following: the available stroke of hydraulic cylinder 441, the effective length of vertical guide rail 41, the net distance from net cage 3 to seabed, the envelope range of mooring system 7, the clearance of data equipment compartment 5, and the minimum allowable dive depth of the fish school.

[0056] Energy storage and control system 6 Convert to target workstation coordinates of net cage 3 Subsequently, the control hydraulic pump station 442 and control valve group 444 drive each hydraulic cylinder 441 to descend synchronously. During the descent, the displacement sensor 447 and pressure sensor 446 provide real-time feedback on the displacement difference, pressure difference, and guide friction status of each hydraulic cylinder 441. When the synchronization error, pressure deviation, guide resistance, lock-up status, or dissolved oxygen data exceeds the preset safety limit, the control system 6 reduces the descent speed, pauses the descent, performs reverse fine-tuning, or executes intermediate lock-up, and then re-activates the control system. The target descent depth is corrected. After cage 3 reaches the typhoon-resistant shelter position, the locking device 45 is activated to restrict the unauthorized sliding of cage 3 in strong sea conditions.

[0057] During the typhoon, the energy storage and control system 6 maintained the operation of aeration equipment, key sensors, and communication systems to ensure the survival conditions of the fish and monitor the platform's status, and recalculated at preset time intervals. To determine whether it is necessary to maintain the current depth, fine-tune the descent depth, or ascend in stages after the sea conditions ease. After the typhoon or severe sea conditions have ended, check the mooring system 7, guidance mechanism 4, hydraulic drive system 44, netting, data equipment compartment 5 for sealing status and fish population status in sequence; once the safety check is passed and the risk index is [not specified], [the system will be considered]. Below the reset threshold After a preset time, the lock is released and the net cage 3 is restored to its normal aquaculture position.

[0058] In practical applications, a medium-sized platform can use a main column diameter of 10m, a net cage outer diameter of 40m, a net cage total height of 20m, a breeding volume of 20,000m³, eight vertical guide rails, and four sets of hydraulic cylinders; a large platform can use a main column diameter of 15m, a net cage outer diameter of 60m, a net cage total height of 30m, a breeding volume of 60,000m³, twelve vertical guide rails, and six sets of hydraulic cylinders; a small platform can use a main column diameter of 6m, a net cage outer diameter of 24m, a net cage total height of 12m, a breeding volume of 5,000m³, six vertical guide rails, and three sets of hydraulic cylinders.
