Description

Technical Field

[0001] The embodiments in this specification relate to the field of marine energy utilization technology, specifically to a marine power generation device and method. Background Technology

[0002] Offshore wind energy, as one of the most promising clean energy sources, has become a crucial pillar of energy transformation due to its abundant resources, renewable nature, and pollution-free operation. Statistics show that the technically exploitable offshore wind power capacity exceeds 71,000 TWh / year, equivalent to 28 times the current electricity demand. Compared to traditional energy sources, offshore wind power projects have three major advantages: firstly, a short construction cycle, typically requiring only 18-24 months from commencement to grid connection; secondly, low operation and maintenance costs, with total lifecycle maintenance expenses accounting for only 15-20% of the total project investment; and thirdly, environmental friendliness, with every 1 million kilowatts of offshore wind power reducing carbon dioxide emissions by 2 million tons annually. These advantages have earned it the reputation of "blue sky and white coal," and its position in the energy mix is ​​increasingly important.

[0003] However, current mainstream marine power generation devices still face significant technical bottlenecks in their widespread application. While these devices exhibit excellent stability (roll angle <5°) in deep water (depth > 50 meters) through deep-draft columns (typically 60-100 meters) and small waterplane area designs, their adaptability in shallow water (depth < 30 meters) is poor, resulting in lower power generation efficiency and stability. Specifically: firstly, limited draft leads to decreased stability, increasing the roll angle to 15-20° under the same sea conditions; secondly, shallow water effects enhance wave nonlinearity, triggering significant heave-pitch coupled motion.

[0004] Therefore, overcoming the problems of poor power generation efficiency and stability in existing technologies and proposing a marine power generation device with high power generation efficiency and stability is a key issue that urgently needs to be addressed. Summary of the Invention

[0076] The technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this specification, and not all embodiments. Based on the embodiments in this specification, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this specification.

[0077] Figure 1This is a schematic diagram of the overall framework of a marine power generation device provided in this specification. This specification provides the operational steps of the methods described in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operational steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many and does not represent the only possible execution order. In actual system or device products, the methods shown in the embodiments or drawings can be executed sequentially or in parallel.

[0078] It should be noted that the terms "first," "second," etc., used in this specification, claims, and the foregoing drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, apparatus, product, or device that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or devices.

[0079] In some embodiments, the marine power generation device may include a wind power generation component 1; a submerged column 5 for supporting the wind power generation component 1; a wave power generation component 3 disposed on the submerged column 5 and movable up and down along the submerged column 5; and an aquaculture cage 4 disposed on the edge of the wave power generation component 3 and movable along the edge.

[0080] The integrated design of the wind power generation component 1, submerged column 5, wave power generation component 3, and aquaculture cage 4 in the marine power generation device achieves the integration of wind power generation, wave power generation, and marine aquaculture functions. The submerged column 5 serves as a fixed reference point for the marine power generation device, allowing the wave power generation component 3 to generate electricity through its vertical movement, achieving complementarity between wind and wave energy and improving power generation continuity. The movement of the aquaculture cage 4 prevents organism attachment, helping to reduce maintenance frequency, while the wave-driven seawater exchange increases the dissolved oxygen level of the aquaculture cage 4, optimizing aquaculture conditions. Furthermore, the shared submerged column 5 between the wave power generation component 3 and the aquaculture cage 4 reduces development costs per unit sea area. The counterweight of the aquaculture cage 4 also lowers the center of gravity of the wind power generation component 1, improving the marine power generation device's resistance to wind and waves. In addition, the submerged column 5 serves as the foundation for the wind power generation component, the kinetic energy transfer medium for wave power generation, and provides an anchoring point for the aquaculture cage, achieving "one column, three uses."

[0081] Please refer to Figure 1 and Figure 2The wind power generation component 1 can use a submerged column 5 as its support structure. The submerged column 5 has a small amplitude of heave movement and high stability, making it suitable for point absorption wave energy devices, such as wave energy generation component 3. The wind power generation component 1 can convert wind energy into electrical energy.

[0082] The wave power generation component 3 can be regarded as a dynamic mass block that slides up and down along the submerged column 5. Its inertia can partially offset the pitching of the wind power generation component 1 under the action of wind at sea, reduce the acceleration of the nacelle of the wind power generation component 1, adapt to multi-directional waves at sea, and thus reduce power generation fluctuations.

[0083] The wave energy generation component 3 can slide up and down along the submerged column 5 under the action of wave energy to convert wave energy into electrical energy. For example, the up and down sliding of the wave energy generation component 3 along the submerged column 5 can also convert the reciprocating motion of sea waves into electrical energy through a built-in hydraulic system or a linear generator or other conversion device.

[0084] The total mass of the aquaculture cage 4 and the aquaculture organisms can be finely adjusted to adjust the overall center of gravity of the wind power generation component 1, and the auxiliary ballast system can maintain the balance of the overall structure of the marine power generation device.

[0085] The wake turbulence generated by the submerged column 5 is relatively small, and the water flow in the aquaculture cage 4 area is relatively stable, which is suitable for the aquaculture of high-value fish (such as salmon and tuna).

[0086] In addition, the deep draft of the submerged column 5 can sink the aquaculture cage 4 to a suitable temperature / nutrient layer for marine aquaculture, such as avoiding the high temperature of the sea surface in summer, thus improving the effect of marine aquaculture.

[0087] The submersible column 5 provides buoyancy and stabilizes the entire marine power generation unit.

[0088] Optionally, the diameter and wall thickness of the submerged column 5 can be determined by balancing stability and construction cost through hydrodynamic analysis.

[0089] The aquaculture cage 4 is located along the edge of the wave power generation component 3 and can move along the edge. It can move independently of the rigid movement of the wind power generation component 1 under the action of wind at sea, reducing the mechanical stress on the cultured organisms. In addition, the movement of the aquaculture cage 4 along the edge of the wave power generation component 3 can improve water exchange and promote the culture environment of cultured organisms (such as fish and shellfish).

[0090] Optionally, the wind power generation component 1 can be a SPAR type wind turbine. A SPAR wind turbine may include a deep-water submerged column and a bottom ballast tank. Most of the mass of the SPAR wind turbine is concentrated at the bottom of the column (ballast tank), providing excellent anti-overturning capability and making it suitable for high-wave sea areas. The SPAR wind turbine can reduce wave-induced heave motion based on a slender submerged column, while allowing for moderate pitching / rolling, which can be optimized through a dynamic control system. SPAR wind turbines can be deployed in sea areas with depths exceeding 50m, where wind energy resources are more abundant and there is no impact on the coastal landscape.

[0091] In some embodiments, the wind power generation component 1 may include: a hub 11; blades 12, which can be connected to the tower via the hub and can rotate around the hub; and a tower 13, which can be located directly above the submerged column.

[0092] The blade 12 can rotate around the hub 11 under the action of wind energy to convert wind energy into electrical energy. The efficient rotation of the blade 12 can reduce the vibration amplitude of the tower 13, indirectly improving the overall power generation stability of the marine power generation device. The rigid support of the tower 13 can provide a stable sliding reference surface for the wave energy device, avoiding the decrease in wave energy conversion efficiency due to structural deformation.

[0093] Please refer to Figure 2 The blade 12 can capture wind energy, which can be converted into rotational mechanical energy through aerodynamic design (such as airfoil profile and twist distribution).

[0094] Alternatively, the blades 12 may be made of salt spray resistant materials (such as glass fiber reinforced epoxy resin) and have a folding or pitch protection design.

[0095] The hub 11 can fix the root of the blade 12 and transfer the wind energy captured by the blade 12 to the generator.

[0096] Optionally, hub 11 can integrate pitch bearings and drive motors to adjust the pitch angle in real time to optimize power or unload extreme loads.

[0097] The tower 13 can connect the hub 11 / nacelle to the submerged column 5, and it can withstand the unbalanced aerodynamic loads when the wind power generation component 1 is running.

[0098] Alternatively, the tower 13 may be a tapered steel cylinder to reduce material usage and accommodate wave load distribution.

[0099] Optionally, the tower 13 may integrate an internal ladder or elevator for maintenance of the pitch system or generator.

[0100] Optionally, the hub 11 of the wind power generation component 1 and the wave energy damping (wave energy generation component 3) can be adjusted synchronously to minimize the vibration of the tower 13.

[0101] In some embodiments, a plurality of connecting rods 51 are provided on the submerged column 5, and the plurality of connecting rods 51 are parallel to the central axis of the submerged column 5; a plurality of connecting holes 32 are provided on the wave energy generation component 3, and one of the connecting rods 51 passes through one of the connecting holes 32; the wave energy generation component 3 can slide along the connecting rods 51.

[0102] Compared to traditional single-column wave energy devices, this symmetrical multi-connector design offers significant performance advantages. First, the multi-connector system provides a more uniform load distribution, distributing wave forces across multiple support points, significantly reducing localized stress levels and extending structural fatigue life. Second, the symmetrical arrangement ensures the stability of the mechanism's movement, avoiding jamming caused by unilateral force application. Third, the cavity structure design not only reduces weight but also creates additional functional space, providing more possibilities for system expansion.

[0103] The water-immersed column 5 can adopt a partially hollowed-out structure design. This structural form significantly reduces the overall weight and construction cost while ensuring sufficient structural strength.

[0104] The cavity structure can be mainly distributed in the upper and middle part of the submerged column 5, which not only retains enough solid part at the bottom for ballast configuration, but also achieves an optimal balance between buoyancy and strength through a carefully designed hollowing ratio. This partially hollowed-out structure not only reduces the amount of material used, but more importantly, it creates a usable three-dimensional space inside the column, providing convenient conditions for subsequent equipment installation and maintenance.

[0105] Optionally, the water-immersed column 5 may include a first section and a second section, with the connecting rod 51 connecting the first section and the second section. Of course, besides the connecting rod 51, the first section and the second section can also be connected in other ways, such as through a connecting column. The central axes of the first section and the second section are parallel.

[0106] Optionally, the connecting rod 51 can also be mounted on the submerged column in other ways. This specification does not specifically limit this embodiment; any method that allows the wave energy generation component 3 to be mounted on the submerged column 5 is acceptable.

[0107] Multiple symmetrically arranged connecting rods 51 can be evenly distributed along the central axis of the submerged column 5. These connecting rods 51 can be made of high-strength alloy steel.

[0108] The number of connecting rods 51 can be at least 12, arranged symmetrically in a circle. The center distance between adjacent connecting rods 51 can be maintained at more than 1.5 times the diameter to ensure sufficient structural stiffness and fluid flow. This multi-column symmetrical arrangement design can effectively disperse wave loads and avoid the stress concentration problem that is prone to occur in traditional single-column sliding structures.

[0109] Optionally, the surface of each connecting rod 51 can be specially treated, including an anti-corrosion coating and a friction-reducing treatment. The anti-corrosion layer can be a composite system of thermally sprayed aluminum and polyurethane topcoat, while the friction-reducing layer can be made of ultra-high molecular weight polyethylene material with a friction coefficient controlled below 0.08.

[0110] Optionally, the main body of the wave energy generation component 3 can adopt a composite structure of buoyancy material and metal frame to ensure structural strength while ensuring sufficient buoyancy.

[0111] Optionally, along the central axis of the wave energy generation component 3, multiple symmetrically distributed high-precision connection holes 32 can be uniformly arranged, and the number, position and size of these connection holes 32 can be perfectly matched with the connection rod 51.

[0112] Optionally, the connecting hole 32 may be fitted with a self-lubricating bearing bushing made of polytetrafluoroethylene composite material, which has excellent wear resistance and self-lubricating properties. The fit tolerance between the connecting hole 32 and the connecting rod 51 is strictly controlled within ±2 mm, which ensures smooth relative sliding and avoids unnecessary shaking caused by excessive clearance.

[0113] When waves act on the wave energy generating component 3, the component 3 will reciprocate up and down along the connecting rod 51. This motion can be converted into electrical energy in various ways. For example, a high-performance permanent magnet can be embedded inside the connecting rod 51, and a multi-phase winding coil can be arranged in the connecting hole 32. When the wave energy generating component 3 moves relative to the component, the coil cuts the magnetic lines of force to generate an induced current. The wave energy generating component 3 can also drive a hydraulic cylinder through a connecting rod to convert the linear motion of the waves into a high-pressure oil flow, which in turn drives a hydraulic motor to generate electricity, which will not be elaborated further here.

[0114] Optionally, the submerged column 5 may include multiple sensors to monitor the stress state of each connecting column, the motion parameters of the wave energy generation component 3, and sea conditions in real time. This data is processed by a dedicated control algorithm to dynamically adjust the damping characteristics of the wave energy generation component 3, ensuring its motion frequency is optimally matched with the main wave frequency, thus achieving resonance enhancement. In extreme sea conditions, a protection mode can be automatically activated, locking the sliding of the wave energy generation component 3 through an electromagnetic braking device to prevent structural overload.

[0115] Optionally, the edge of the connecting hole 32 can be provided with a special waterproof sealing structure, using a multi-level labyrinth seal combined with an elastic sealing ring to effectively prevent seawater from seeping into the interior of the column and causing corrosion.

[0116] Optionally, the main structure of the submerged column 5 can be made of high-strength low-alloy marine steel with a yield strength of not less than 355 MPa.

[0117] Alternatively, the connecting rod 51 can be made of precipitation-hardened stainless steel with a tensile strength of over 800 MPa.

[0118] Optionally, the frame of the wave energy generation component 3 can be made of seawater-resistant aluminum alloy, which reduces weight and ensures corrosion resistance.

[0119] Optionally, the bearing bushing of the connecting hole 32 can be made of modified polytetrafluoroethylene composite material, which has a service life of more than 10 years in seawater environment.

[0120] Optionally, a periodic low-frequency vibration mode can be set to prevent the attachment and growth of marine organisms through the slight vibration of the wave energy power generation component 3.

[0121] In some embodiments, the wave energy generation component 3 includes a housing and a plurality of oscillating wave energy systems 31 disposed inside the housing; the housing is provided with the plurality of connection holes 32; each of the oscillating wave energy systems 31 includes a connecting rod 317, a mover 316 and a stator 315; the connecting rod 317 is parallel to the central axis of the submerged column 5, the mover 316 is slidable along the connecting rod 317, and the stator 315 is used to output electrical energy in response to the sliding of the mover 316.

[0122] The wave energy generation component 3 adopts an innovative multi-unit integrated design, with multiple symmetrically distributed helical wave energy systems 31 uniformly embedded within its shell along its central axis. This modular arrangement not only improves the system's reliability (a single unit failure does not affect overall operation) but also automatically optimizes energy capture efficiency based on wave direction. Each helical wave energy system 31 is an independent energy conversion unit, employing a precisely matched mechanical-electromagnetic composite structure to ensure long-term stable operation in harsh marine environments.

[0123] Optionally, the outer shell 311 can be injection molded from glass fiber reinforced nylon composite material, with a wall thickness controlled at 8-10mm, ensuring structural strength while reducing weight. Its interior is precision-machined and features guide grooves and limiting structures to ensure the precise movement of internal components.

[0124] Optionally, the housing 311 can be equipped with a dual sealing system at both ends, including a primary seal using fluororubber O-rings and a secondary seal using a labyrinth structure, to jointly prevent seawater ingress. Heat dissipation fins can also be integrated on the exterior of the housing to cool the internal components through natural seawater convection.

[0125] Optionally, each of the helical wave energy systems 31 includes a spring 312. The spring 312 may be made of corrosion-resistant nickel-titanium alloy material and undergo a special heat treatment process to have excellent fatigue resistance.

[0126] Optionally, the stiffness of the spring 312 can be designed according to typical wave cycles, for example, 50-100 N / mm, and the pre-compression can be adjusted to adapt to different sea conditions.

[0127] Optionally, the two ends of the spring 312 can be fixed to the housing 311 by means of anti-loosening threaded joints and coated with a special anti-fretting wear coating.

[0128] Optionally, a travel limiter may also be provided inside the spring 312 to prevent the spring from being over-compressed and causing permanent deformation under overload conditions.

[0129] Optionally, the connecting rod 317 can be made of aerospace-grade titanium alloy by precision grinding, and the surface is nitrided to form a 0.1mm thick hardened layer with a hardness of HRC60 or higher.

[0130] Optionally, precision guide grooves can be machined along the entire length of the connecting rod 317 to cooperate with the ball bearings in the mover 316 to ensure linearity of motion and low friction.

[0131] Optionally, both ends of the connecting rod 317 can be connected to the housing 311 via universal joints, allowing a deflection angle of ±2° to compensate for installation errors and wave oblique impacts.

[0132] Optionally, the center of the mover 316 can be a high-energy-product neodymium iron boron permanent magnet with a nickel-copper-nickel triple-layer protective coating. The permanent magnet is surrounded by magnetically conductive pure iron pole shoes, optimizing the magnetic circuit distribution. The entire magnetic assembly can be mounted in an aluminum alloy bracket with an interference fit. The bracket is equipped with four sets of linear ball bearings, forming a precision sliding pair with the connecting rod 317.

[0133] Optionally, the two ends of the mover 316 can also be equipped with non-contact position sensor targets for real-time monitoring of motion.

[0134] Optionally, the stator 315 can be fixed to the inner wall of the housing 311, and the segmented structure facilitates installation and maintenance.

[0135] Optionally, the stator 315 core is made of 0.2mm thick silicon steel sheets laminated together, and the pole shoe shape is designed with electromagnetic field optimization. The windings use seawater-resistant polyimide enameled wire, which is vacuum pressure impregnated. The three-phase windings can be arranged in a distributed short-pitch configuration to effectively suppress harmonics.

[0136] Optionally, buffer pads made of high-damping polyurethane material can be provided at both ends of the stator 315 to prevent mechanical impact when the mover 316 moves to its limit position.

[0137] Please refer to Figure 3 and Figure 4 When the marine power generation device is working, the waves propel the entire wave energy generation component 3 in a helical motion, driving multiple internal helical wave energy systems 31 to work synchronously. As the outer shell 311 moves up and down with the waves, the mover 316 will displace relative to the outer shell due to inertia, compressing or stretching the spring 312. This relative motion causes the permanent magnet magnetic field of the mover 316 to cut the stator 315 winding, generating an induced electromotive force according to Faraday's law of electromagnetic induction. Each working cycle includes two stages: energy capture and conversion. During the wave rise phase, the inertial lag of the mover causes the spring to store potential energy; during the wave fall phase, the spring releases energy to drive the mover in the opposite direction, achieving bidirectional power generation.

[0138] In some embodiments, each of the helical wave energy systems 31 may further include a counterweight 314, a spring 312, and a limiter 313. The counterweight 314 may be connected to the mover 316 and may drive the mover 316 to slide along the connecting rod 317. The spring 312 may be connected to the counterweight 314, and the limiter 313 may be used to limit the movement range of the counterweight.

[0139] Each helical wave energy system 31 employs a precision-designed mechanical resonant structure, mainly comprising three components: a counterweight 314, a spring 312, and an intelligent limiter 313. These components, through specific design, together constitute a highly efficient and reliable wave energy conversion unit.

[0140] Optionally, the counterweight 314 can be designed with an axial through hole, forming a sliding fit with the connecting rod 317 through a high-precision ball bearing. The upper surface of the counterweight 314 can be machined with an annular groove for mounting the displacement sensor target; the lower surface can have a spring connection interface with an anti-loosening threaded locking structure. The surface of the counterweight can undergo a special composite coating treatment, including a 50μm thick electroless nickel plating layer as the bottom layer and a 20μm thick polytetrafluoroethylene coating as the outer layer, which prevents seawater corrosion and reduces motion resistance. Guide grooves can also be machined on the side of the counterweight, engaging with the guide key on the inner wall of the outer casing 311 to ensure the straightness of the motion trajectory and prevent additional frictional loss caused by rotation.

[0141] Optionally, spring 312 can be a custom-designed conical helical spring, undergoing vacuum heat treatment and stress relief processes to achieve excellent fatigue resistance. Both ends of spring 312 can be equipped with precision-machined connecting seats, which connect to the counterweight 314 and the base via pins, allowing a deflection angle of ±3°. A non-contact displacement sensor can be installed inside spring 312 to monitor the compression state in real time, with data transmitted wirelessly to the control system. To prevent seawater corrosion, the surface of spring 312 can be multi-layered: the bottom layer can be an electroplated zinc layer, the middle layer can be an epoxy resin coating, and the outermost layer can be a polyurethane protective film.

[0142] Optionally, the limiter 313 can employ an intelligent hydraulic buffer design, comprising two subsystems: mechanical limiting and electronic control. The mechanical part can consist of a high-strength aluminum alloy housing, a polyurethane buffer pad, and a hydraulic damper, capable of absorbing over 95% of impact energy. The electronic control part can include a position sensor, a microprocessor, and an electromagnetic regulating valve, dynamically adjusting the damping force based on real-time monitoring of the counterweight's movement. The limiter 313 can be installed at both ends of the counterweight's movement path. When an abnormal impact is detected, the limiter can activate an emergency braking mode within 5ms, completely locking the counterweight's movement.

[0143] Please refer to Figure 4 When the marine power generation device is operating, the counterweight 314 is rigidly connected to the mover 316 via a rigid connector. The connector can be made of titanium alloy and has universal joints at both ends to compensate for installation errors. When waves push the wave energy generation component 3 up and down, the counterweight 314 will displace relative to the outer shell 311 due to inertia. This relative motion causes the spring 312 to be compressed or stretched, storing or releasing elastic potential energy. At the same time, the mover 316, fixed to the counterweight, moves along with it, and its permanent magnet magnetic field cuts the stator winding to generate an induced electromotive force. During the wave rise phase, the inertia of the counterweight causes it to lag behind the movement of the outer shell, and the spring is compressed to store energy; during the wave fall phase, the spring releases energy to push the counterweight to move in the opposite direction, achieving bidirectional energy capture. Throughout the process, the limiter 313 monitors the displacement of the counterweight in real time. When the amplitude exceeds the safety threshold, it controls the movement amplitude through progressive damping to avoid mechanical overload.

[0144] In some embodiments, the aquaculture cage 4 may include: a hollow tubular mesh 41; a plurality of connecting posts 42, which are uniformly and symmetrically arranged on the mesh 41 along the central axis of the mesh 41; the connecting posts 42 are connected to the wave energy generation component 3 through the connecting mechanism 2.

[0145] Through the netting 41 and symmetrically distributed connecting columns 42, a marine aquaculture-vibration reduction composite system can be formed, which works in conjunction with the wind power generation component 1 and the wave power generation component 3. The hollow tubular structure of the aquaculture cage as a whole can ensure sufficient aquaculture volume and achieve an optimal matching ratio with the wind power generation component 1.

[0146] Optionally, the connecting posts 42 can be made of hollow fiberglass composite material, combining lightweight and high strength. Each connecting post 42 can be filled with polyurethane foam, which increases buoyancy and improves impact resistance. The surface of the connecting posts 42 can be specially treated, including a bottom layer of fiberglass reinforcement, a middle layer of weather-resistant polyester resin, and an outer layer of antifouling coating, to ensure corrosion resistance in seawater environments.

[0147] Optionally, the upper end of the connecting post 42 can be connected to the wave energy generation component 3 via a universal joint, allowing a swing angle of ±15°. This flexible connection method can effectively mitigate the instantaneous load caused by wave impact. A load sensor can be installed at the connection point to monitor the tension data in real time. The lower end can be connected to the mesh 41 via a specially designed clamp made of aluminum alloy with an inner rubber pad, ensuring a firm connection while avoiding damage to the mesh fibers. The installation angle of each connecting post 42 can be optimized through hydrodynamic calculations to ensure the best damping effect under wave action.

[0148] Optionally, the netting 41 can be woven from ultra-high molecular weight polyethylene, which has advantages such as high strength and corrosion resistance, reducing the number of maintenance times during sea transport and lowering replacement costs. The mesh size can be adjusted according to the aquaculture species.

[0149] Optionally, the mesh 41 can be made using a hexagonal weaving process, with a tensile strength exceeding 200kN / m and a knot strength retention rate of over 90%. To improve durability, the mesh can undergo special treatment: the core is made of high-strength polyethylene fiber, the outer layer is coated with a weather-resistant polyurethane coating, and the outermost layer is impregnated with an antifouling agent (the main components of which are silicates and copper ions).

[0150] Optionally, buoyancy blocks and counterweights can be evenly distributed on the netting 41. The buoyancy blocks are made of closed-cell foam plastic, and the counterweights are plastic-coated lead blocks, which together maintain the ideal shape of the aquaculture net cage.

[0151] Please refer to Figure 5Under the influence of wave energy, the aquaculture cage 4 exhibits a unique vibration reduction function. When waves propel the wave energy generator 3, the netting 41 generates significant resistance in the water flow. This resistance is transmitted to the entire system through the connecting column 42, forming a damping force opposite to the wave force. The specific mechanism involves three levels: First, the large surface area of ​​the netting generates viscous resistance when moving in the water; second, the mesh structure causes water turbulence, consuming wave energy; and third, the movement of the cultured organisms within the aquaculture cage further increases water disturbance.

[0152] Optionally, the internal space of the aquaculture cage 4 can be divided into multiple zones. For example, the upper 1 / 3 is the feeding area, the middle is the growth area, and the lower is the waste collection area; multiple layers of horizontal dividing nets can be installed to prevent excessive concentration of fish; an automatic feeding system and environmental monitoring sensors can be installed.

[0153] In some embodiments, the connecting mechanism 2 may include a plurality of connecting gears 21; each connecting gear 21 corresponds to a connecting post 42; the center 211 of each connecting gear 21 may be a threaded hole structure; the side surface of each connecting post 42 may be a threaded structure; the threaded hole structure of the center 211 of each connecting gear 21 may mesh with the threaded structure of the corresponding connecting post 42 side surface.

[0154] Through a precisely designed screw-hole-threaded column coupling mechanical structure, dynamic connection and load transfer can be achieved between the wave energy generation component 3 and the aquaculture cage 4. The screw-hole-threaded column coupling mechanical structure ensures the reliability of the connection while allowing necessary relative movement.

[0155] Optionally, the connecting gear 21 can be made of special alloy steel (42CrMo) through precision forging and heat treatment. The gear can be modified to reduce meshing noise, and chamfers can be provided on both sides to prevent edge stress concentration.

[0156] Optionally, the center 211 of each connecting gear 21 can be machined with a unique threaded hole structure, different from ordinary threaded holes, and can adopt a variable tooth profile design: the inlet section has a 30° guiding cone angle, the middle section has a trapezoidal thread, and the end has a relief groove. The threaded hole structure can achieve a thread accuracy of 6H grade, a surface roughness Ra≤1.6μm, and is phosphated to enhance wear resistance.

[0157] Optionally, the connecting post 42 can be precision machined from high-strength stainless steel. The side surface of the connecting post 42 can feature special threads that perfectly match the bolt hole structure. The side surface of the connecting post 42 can be rolled to enhance fatigue life.

[0158] The engagement of the threaded hole structure at the center 211 of the connecting gear 21 with the threaded structure on the side surface of the corresponding connecting post 42 has multiple functional advantages:

[0159] First, the threaded engagement provides a reliable axial force transmission path, evenly distributing the wave load on the aquaculture cage 4 to multiple connecting gears 21;

[0160] Secondly, it allows for precise length adjustment during installation (adjustment accuracy ±1mm) to compensate for manufacturing and installation errors;

[0161] Furthermore, the helix angle design of the threaded pair gives the system a certain degree of buffering and vibration reduction capability, which can absorb some impact energy.

[0162] In some embodiments, the outer wall 212 of each connecting gear 21 may be a toothed structure; the side surface of the submerged column 5 may be provided with an annular toothed track; the toothed structure of the outer wall 212 of the connecting gear 21 may mesh with the annular toothed track on the side surface of the submerged column 5.

[0163] The connecting gear 21 achieves dynamic connection and force transmission between the aquaculture cage 4 and the submerged column 5 through a gear-track meshing mechanical structure. This gear-track meshing mechanical structure design not only provides reliable connection strength but also allows the aquaculture cage 4 to undergo controllable relative movement under wave action.

[0164] The toothed structure of the outer wall 212 of the connecting gear 21 meshes with the annular toothed track on the side surface of the submerged column 5, offering multiple functional advantages:

[0165] First, the connecting gear 21 provides precise motion control, transforming the random swaying of the aquaculture cage 4 into a controllable reciprocating rotation;

[0166] Secondly, the simultaneous meshing of multiple teeth makes the load distribution more uniform, which helps to reduce the force on a single tooth.

[0167] In some embodiments, the outer wall 212 of each connecting gear 21 can be a toothed structure; the outer edge of the wave power generation component 3 can be provided with an annular toothed track 33; the toothed structure of the outer wall 212 of the connecting gear 21 can mesh with the annular toothed track 33 on the outer edge of the wave power generation component 3.

[0168] The connecting gear 21 achieves dynamic connection and force transmission between the aquaculture cage 4 and the wave energy generation component 3 through a gear-track meshing mechanical structure. This gear-track meshing mechanical structure design not only provides reliable connection strength but also allows the aquaculture cage 4 and the wave energy generation component 3 to perform controllable coordinated movement under the action of waves.

[0169] Optionally, the outer wall of the connecting gear 21 can be specially machined to form a curved surface structure that perfectly matches the outer shell of the wave power generation component 3, with the radius of curvature error controlled within ±0.1mm. The contact surface can be processed using high-precision grinding, with a surface roughness Ra≤0.8μm, and plated with a 0.05mm thick hard chrome layer, achieving a hardness of HV900 or higher. Adaptive adjustment shims can be provided between the mating surfaces, with thickness adjustable in stages within the range of 0.1-1mm to ensure that the contact area after assembly is greater than 85%. The outer wall edge can be machined with a labyrinth-type sealing groove, with an embedded fluororubber sealing strip, effectively preventing seawater infiltration.

[0170] Optionally, the tooth structure of the outer wall 212 of the connecting gear 21 can adopt a specially designed double pressure angle involute tooth profile: 25° on the working side and 20° on the non-working side. This asymmetrical design can improve the load-bearing capacity and reduce noise during reverse impact.

[0171] Optionally, a double-row tapered roller bearing with a radial clearance of 0.02-0.05 mm can be installed in the shaft hole of the connecting gear 21, which can withstand both radial and axial loads simultaneously.

[0172] Optionally, the annular toothed track 33 on the outer shell of the wave energy generation component 3 can be designed in segments and connected by precision locating pins. The tooth surface of the annular toothed track 33 can be subjected to ultrasonic hardening treatment, and the tooth profile parameters are perfectly matched with the connecting gear 21, but the tooth height is slightly larger by 0.1-0.2 mm to form an appropriate meshing clearance. A special transition tooth design can be used at the joint of the annular toothed track 33 to ensure that the connecting gear 21 passes smoothly without impact.

[0173] Please refer to Figure 6 The meshing of the toothed structure of the outer wall 212 of the connecting gear 21 with the annular toothed track 33 on the edge of the shell of the wave energy generation component 3 has multiple functional advantages: First, the transmission of the connecting gear 21 provides precise motion control, transforming the random swaying of the aquaculture cage 4 into a controllable reciprocating rotation; second, the simultaneous meshing of multiple teeth makes the load distribution more uniform, which helps to reduce the force on a single tooth; third, the self-centering characteristic of the involute tooth shape compensates for installation errors and deformation.

[0174] In addition, the aquaculture cage 4 can serve as an external damper for multiple swaying wave energy systems 31 in the wave energy power generation component 3, preventing the swaying wave energy system 31 from moving too much under extreme wind and wave impacts, thus achieving a clever balance between power generation efficiency and power generation stability.

[0175] Specifically, the motion of the netting 41 under wave action generates significant viscous drag in seawater. According to the Morison equation, this drag is proportional to the square of the relative velocity, and its damping coefficient C_d can reach 1.5-2.1, far exceeding the effectiveness of traditional dampers. For example, under a wave height of 4 meters, a single aquaculture net cage 4 can generate a peak damping force of approximately 1200 kN. The inertial effect brought about by the overall mass of the net cage can also effectively counteract the acceleration of the heave wave energy system 31, significantly reducing the structural impact load. Furthermore, the eddy current field induced by the mesh structure can additionally dissipate 15-20% of the wave energy. This energy dissipation has broadband characteristics and can effectively suppress wave excitation at different frequencies.

[0176] In some embodiments, when wind and waves jointly impact the integrated marine power generation device, the blades 12 in the wind power generation component 1 can rotate around the hub 11, driving the generator to convert wind energy into electrical energy. Simultaneously, due to the swaying and pitching motions of the wind power generation component 1 under the influence of wave undulations, the counterweights 314 within the multiple swaying wave energy systems 31 can carry the mover 316 in a reciprocating motion on the connecting rod 317, causing the stator 315 to cut magnetic field lines, thereby converting wave energy into electrical energy. The wave energy generation component 3 can slide freely on the connecting rod 51, increasing the relative motion between the mover 316 and the stator 315 within the multiple swaying wave energy systems 31, thus improving wave energy utilization efficiency. Furthermore, the coil wound on the mover 316 allows for remote adjustment of the current magnitude. This, combined with the external fixed damping provided by the aquaculture cage 4, and the preset internal damping of the helical wave energy system 31 according to the actual sea conditions, achieves a comprehensive consideration of power generation efficiency and stability based on both external fixed damping and internal damping. The preset internal damping of the helical wave energy system 31 can be referenced... Figure 7 The netting 41 is mounted on the connecting gear 21 via the connecting post 42. The outer surface of the connecting gear 21 smoothly engages with the toothed track 33 of the wave power generation component 3. When the wind power generation component 1 moves, the netting can slide smoothly 360° along the toothed track 33 of the wave power generation component 3. This not only increases the resistance and reduces the waves of the wind power generation component 1, but also exchanges oxygen in the aquaculture cage 4, thereby increasing the aquaculture output rate.

[0177] The marine power generation device provided in the embodiments of this specification may include a wind power generation component; a submerged column for supporting the wind power generation component; a wave power generation component disposed on the submerged column and movable up and down along the submerged column; and an aquaculture cage disposed on the edge of the wave power generation component and movable along the edge. Compared with existing methods, in the marine power generation device of this specification embodiment, the submerged column serves as a fixed anchor point for the marine power generation device, and the wave power generation component can generate electricity using its vertical movement, achieving complementarity between wind and wave energy and improving power generation efficiency. The counterweight of the aquaculture cage can also lower the center of gravity of the wind power generation component, improving the wind and wave resistance of the marine power generation device. In addition, the movement of the aquaculture cage can prevent biological attachment, helping to reduce maintenance frequency, while the seawater exchange driven by wave energy can increase the dissolved oxygen content of the aquaculture cage and optimize aquaculture conditions. The submerged column is both the foundation of the wind power generation component and the kinetic energy transfer medium for wave power generation, while also providing an anchor point for the aquaculture cage, achieving "one column, three uses".

[0178] Corresponding to the above-described marine power generation device, this specification also provides a marine power generation method. Figure 8 This is a flowchart illustrating an ocean power generation method provided in the embodiments of this specification. In specific implementation, it includes the following steps:

[0179] S801: Controls wind power generation components to generate wind power.

[0180] S802: Control the water-immersed column to support the wind power generation component.

[0181] S803: Control the wave energy generation component to move up and down along the submerged column to generate wave energy.

[0182] S804: Control the aquaculture cage to move along the edge of the wave energy generating component.

[0183] In some embodiments, corresponding to the above-described marine power generation method, when wind and waves jointly impact the integrated marine power generation device, the blades 12 in the wind power generation component 1 can rotate around the hub 11, driving the generator to convert wind energy into electrical energy. Simultaneously, due to the swaying and pitching motions of the wind power generation component 1 under the influence of wave undulations, the counterweights 314 within the multiple swaying wave energy systems 31 can carry the mover 316 in a reciprocating motion on the connecting rod 317, causing the stator 315 to cut magnetic field lines, thereby realizing the conversion of wave energy into electrical energy. The wave energy generation component 3 can slide freely on the connecting rod 51, increasing the relative motion between the mover 316 and the stator 315 within the multiple swaying wave energy systems 31, thus improving wave energy utilization efficiency. Furthermore, the coil wound on the mover 316 allows for remote adjustment of the current magnitude. This, combined with the external fixed damping provided by the aquaculture cage 4, and the preset internal damping of the helical wave energy system 31 according to the actual sea conditions, achieves a comprehensive consideration of power generation efficiency and stability based on both external fixed damping and internal damping. The preset internal damping of the helical wave energy system 31 can be referenced... Figure 7 The netting 41 is mounted on the connecting gear 21 via the connecting post 42. The outer surface of the connecting gear 21 smoothly engages with the toothed track 33 of the wave power generation component 3. When the wind power generation component 1 moves, the netting can slide smoothly 360°, thereby increasing the resistance and reducing the waves of the wind power generation component 1, while also exchanging oxygen in the aquaculture cage 4 and increasing the aquaculture output rate.

[0184] As can be seen from the above, the marine power generation method provided in the embodiments of this specification can control wind power generation components to generate wind power; control submerged columns to support the wind power generation components; control wave power generation components to move up and down along the submerged columns to generate wave power; and control aquaculture cages to move along the edges of the wave power generation components. Compared with existing methods, in the marine power generation device of the embodiments of this specification, the submerged columns serve as fixed anchor points for the marine power generation device, and the wave power generation components can utilize their vertical movement to generate electricity, achieving complementarity between wind and wave energy and improving power generation efficiency. The counterweight of the aquaculture cages can also lower the center of gravity of the wind power generation components, improving the wind and wave resistance of the marine power generation device. In addition, the movement of the aquaculture cages can prevent biological attachment, helping to reduce maintenance frequency, while the wave-driven seawater exchange can increase the dissolved oxygen content of the aquaculture cages and optimize aquaculture conditions. The submerged columns are not only the foundation of the wind power generation components, but also the kinetic energy transfer medium for wave power generation, and provide anchor points for the aquaculture cages, achieving "one column for three uses".
