Description

Technical Field

[0001] This invention relates to the field of deep-sea aquaculture technology, and more specifically, to a flexible net cage for wave power generation. Background Technology

[0002] After years of development, nearshore aquaculture has faced problems such as overexploitation of resources and environmental pollution (e.g., eutrophication and disease transmission). Deep-sea cage aquaculture can shift aquaculture activities to more open sea areas, reducing pressure on nearshore ecosystems. Moreover, the fast water flow and strong water exchange capacity in deep-sea areas help improve the aquaculture environment, reduce disease occurrence, and improve the health and product quality of farmed fish.

[0003] Currently, deep-sea cages are classified into bottom-mounted, semi-submersible, and fully submersible types. Semi-submersible cages are widely used due to their slightly lower cost. Semi-submersible cages are further classified into truss-type and gravity-type cages based on the installation method of the netting. Among these, the structural safety and stability of deep-sea cages are key technologies. Whether actively resisting waves or passively resisting waves (avoiding or submerging), they must be able to withstand typhoons.

[0004] However, traditional cages are mostly rigid truss structures, which rely on increasing the strength coefficient of the rigid structure to resist typhoons, but the effect is poor and very expensive. Summary of the Invention

[0005] The purpose of this invention is to provide a flexible wave power generation cage to alleviate the technical problems of existing technologies that rely on increasing the strength coefficient of rigid structures to resist typhoons, which is ineffective and very expensive.

[0006] This invention provides a flexible wave power generation cage, comprising: a floating frame inside the cage, a power generation component, and a floating frame assembly.

[0007] The floating frame in the box has multiple connecting parts spaced apart along its circumference.

[0008] The power generation component includes multiple generators, each of which is connected to a corresponding connection part.

[0009] The floating frame assembly is located on both sides of the floating frame in the container and is connected to the drive ends of multiple generators.

[0010] Among them, the side of the float assembly away from the float in the box is arc-shaped and bulges outward in the direction away from the float in the box, and the outer contour of the float in the box and the float assembly is teardrop-shaped.

[0011] Furthermore, the floating platform assembly includes a first floating platform and a second floating platform.

[0012] The first floating frame is rotatably connected to the drive end of multiple generators on one side of the floating frame inside the container.

[0013] The second floating frame is rotatably connected to the drive end of multiple generators on the other side of the floating frame in the container.

[0014] The curvature of the first floating platform is smaller than that of the second floating platform.

[0015] An anchor chain assembly for mooring is provided at the end of the first floating platform that is furthest from the second floating platform.

[0016] Furthermore, both the first and second floating platforms include buoyancy tubes and reinforcing rods.

[0017] The buoyancy tube is arranged in an arc shape and its two ends are connected to the two ends of the reinforcing rod. The two ends of the buoyancy tube form hinged ends for hinged connection with the generator.

[0018] Furthermore, the anchor chain assembly has a connecting end and a sinking end.

[0019] The connection end is connected to multiple anchor cables, which are respectively connected to the first floating frame.

[0020] The lower end is used to connect a counterweight to sink to the bottom of the water.

[0021] Furthermore, the generator is a dual-shaft generator;

[0022] The power generation components also include speed-increasing gearboxes in number relative to the number of dual-shaft generators;

[0023] One end of the dual-shaft generator is hinged to the hinged end, and the other end is connected to the connecting part through a speed-increasing gearbox.

[0024] Furthermore, the connection part is a connecting flange.

[0025] One end of the speed-increasing gearbox is connected to the connecting flange, and the other end is connected to the drive shaft of the generator.

[0026] Furthermore, the hinged end is a fork arm structure.

[0027] The fork arm structure has a splined shaft.

[0028] The generator is connected to the splined shaft so that the dual-shaft generator can rotate circumferentially along the splined shaft.

[0029] Furthermore, the wave power generation flexible cage also includes a mesh cover.

[0030] The floats and buoyancy tubes in the container are all equipped with handrails along their own extension direction.

[0031] The netting is hung on the support pole and has a sinker at the bottom to form a net cage below the floats and float frame components in the cage.

[0032] Furthermore, the mesh garment includes a first mesh garment, a second mesh garment, and a third mesh garment.

[0033] The first net, the second net, and the third net are respectively positioned below the first floating frame, below the container floating frame, and below the second floating frame to form the first net compartment, the second net compartment, and the third net compartment, respectively.

[0034] Furthermore, the floating frame inside the container forms a tower.

[0035] The tower is equipped with a power source that is electrically connected to multiple generators.

[0036] Beneficial effects:

[0037] In this invention, the floating frame and floating frame assembly within the cage form a teardrop-shaped outer contour, allowing water flow to bypass more smoothly, reducing eddies and resistance peaks, thereby lowering the fluid resistance coefficient and reducing the force of the water flow on the cage. Furthermore, when subjected to wave impact, the floating frame and floating frame assembly can swing through the hinge points to unload the wave load. During the swinging process, the floating frame and floating frame assembly rotate relative to each other, thereby driving the drive end of the generator to rotate, converting the mechanical energy of the waves into electrical energy, achieving self-powered supply or energy storage, and improving energy self-sufficiency. Moreover, the generator can absorb and disperse the wave impact energy during the work process, avoiding local stress concentration in the structure, thereby extending the life of the wave power generation cage. This invention uses the floating frame and floating frame assembly to form a streamlined outer contour to reduce the force of water flow, and adopts flexible connections to improve adaptability in harsh sea conditions. It can also convert wave mechanical energy into electrical energy, improving energy self-sufficiency, and has excellent resistance to wind and waves, while being inexpensive.

[0053] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0054] Please see Figures 1 to 6 The wave power generation flexible cage provided in this embodiment includes a floating frame 100, a power generation component 200, and a floating frame component 300.

[0055] Combination Figure 1 The containerized float 100 has multiple connecting parts spaced apart along its circumference. The power generation assembly 200 includes multiple generators, each of which is connected to one of the multiple connecting parts. The float assembly 300 is located on both sides of the containerized float 100 and is connected to the drive ends of the multiple generators.

[0056] Furthermore, in this embodiment, the side of the float assembly 300 away from the float 100 in the box is arc-shaped and bulges outward in the direction away from the float 100 in the box, and the outer contours of the float 100 in the box and the float assembly 300 are teardrop-shaped.

[0057] Specifically, in this embodiment, the float 100 and the float assembly 300 in the box are connected to form a teardrop-shaped outer contour. When water flows through the flexible net box for wave power generation, the water can flow more smoothly, reducing eddies and resistance peaks, thereby reducing the fluid resistance coefficient and reducing the force of the water flow on the flexible net box for wave power generation.

[0058] When the flexible wave-powered cage is subjected to wave impact, the floating frame 100 and floating frame assembly 300 inside the cage can swing through the hinge points, thereby unloading the wave load. In addition, during the swinging process of the floating frame 100 and floating frame assembly 300 inside the cage, the floating frame 100 and floating frame assembly 300 rotate relative to each other, thereby driving the drive end of the generator to rotate, converting the mechanical energy of the waves into electrical energy, realizing self-powered power supply or energy storage, and improving energy self-sufficiency.

[0059] In addition, the generator can provide damping force during rotation, thereby further absorbing and dispersing wave impact energy, avoiding local stress concentration in the structure, and thus extending the life of the wave power generation cage. The wave power generation flexible cage provided in this embodiment has a streamlined outer contour formed by the floating frame 100 and the floating frame assembly 300 in the cage to reduce the force of water flow, and adopts flexible connection to improve adaptability in harsh sea conditions. It can also convert wave mechanical energy into electrical energy, improve energy self-sufficiency, and has excellent resistance to wind and waves, and is inexpensive.

[0060] In this embodiment, the float assembly 300 includes a first float 310 and a second float 320.

[0061] Combination Figure 2 , Figure 4 and Figure 5 The first float 310 is rotatably connected to the drive ends of multiple generators on one side of the in-cabin float 100. The second float 320 is rotatably connected to the drive ends of multiple generators on the other side of the in-cabin float 100. The curvature of the first float 310 is smaller than that of the second float 320. An anchor chain 400 assembly for mooring is provided at the end of the first float 310 away from the second float 320.

[0062] Specifically, in this embodiment, the first float 310 has a smaller curvature and a gentler frontal surface, making it more suitable as the structural foundation for the mooring end. The second float 320 has a larger curvature, enhancing the streamlined profile of the tail section and further reducing wake drag when water flows through it.

[0063] Under this asymmetrical arc structure, the anchor chain 400 assembly is located at the far end of the first floating frame 310, making it easier for the wave power generation flexible cage provided in this embodiment to naturally maintain the attitude of the cage head (first floating frame 310 side) facing the current and the cage tail (second floating frame 320 side) following the current in the flow field. It works in conjunction with the single-point mooring system to ensure that the cage always faces the mainstream direction with the least resistance, significantly reducing mooring load and structural fatigue.

[0064] Meanwhile, the anchor chain 400 assembly installed on the first floating frame 310 is concentrated in the area where the mooring force acts on the structure and is the strongest and most stable, avoiding the mooring point being located in a part with a large curvature or high structural flexibility, thereby improving mooring safety and overall system reliability.

[0065] In this embodiment, both the first float 310 and the second float 320 include a buoyancy tube 311 and a reinforcing rod 312. The buoyancy tube 311 is arranged in an arc shape and its two ends are connected to the two ends of the reinforcing rod 312. The two ends of the buoyancy tube 311 form hinged ends for hinged connection with the generator.

[0066] Combination Figure 3Taking the first float 310 as an example, specifically, in this embodiment, the buoyancy tube 311 is arranged along an arc to form a teardrop-shaped outer contour with the float 100 in the box. The buoyancy tube 311 provides the necessary buoyancy while maintaining the overall streamlined shape, avoiding turbulence caused by structural protrusions or bends, and further reducing water flow resistance.

[0067] Among them, the reinforcing rod 312 connects the two ends of the buoyancy tube 311 and forms a stable triangular or frame structure with the buoyancy tube 311, which enhances the rigidity and overall deformation resistance of the first float 310 and the second float 320, and can suppress vibration and fatigue damage, especially under wave impact.

[0068] In this embodiment, the anchor chain 400 assembly has a connecting end and a sinking end. The connecting end is connected to multiple anchor cables, which are respectively connected to the first floating frame 310.

[0069] It should be noted that in this embodiment, the sinking end is used to connect a counterweight to sink to the bottom of the water.

[0070] Specifically, in this embodiment, the connecting end is connected to three anchor cables, and the connection points of the three anchor cables to the first floating frame 310 are evenly spaced.

[0071] With this structure, the three anchor cables achieve uniform distribution of mooring force, effectively avoiding stress concentration and structural fatigue that are easily caused by single-point mooring, and significantly enhancing mooring reliability under the combined action of wind, waves and current.

[0072] Furthermore, in this embodiment, the sinking end is connected to a sinker and a high-holding-force anchor to sink to the bottom of the water, thereby providing sufficient bottom holding force for the first float 310 and the second float 320 of the floating frame 100 in the box, thus ensuring that it does not drift or capsize under severe sea conditions.

[0073] This embodiment uses a multi-anchor cable distributed mooring structure combined with bottom counterweight to form a "distributed above and stable below" mooring mechanism, which not only ensures that the cage is always oriented towards the current, but also greatly reduces the risk of mooring system failure, thereby improving long-term safety and operational reliability in complex deep-sea environments.

[0074] Combination Figure 6 In this embodiment, the generator is a dual-shaft generator. The power generation assembly 200 also includes speed-increasing gearboxes in number corresponding to the number of dual-shaft generators.

[0075] One end of the dual-shaft generator is hinged to the hinged end, and the other end is connected to the connecting part through a speed-increasing gearbox and can rotate around the circumference of the dual-shaft generator.

[0076] In this embodiment, one end of the dual-shaft generator is directly hinged to the hinged end of the floating frame, while the other end is connected to the connecting part of the floating frame 100 in the box through a speed-increasing gearbox, forming a highly efficient transmission path for bidirectional power input and speed-increasing output.

[0077] When the wave action causes the floating frame 100 in the box to rotate relative to the floating frames on both sides, the dual-shaft generator can absorb the mechanical energy generated by the rotation and convert the low-speed, high-torque wave motion into high-speed, low-torque rotational motion through the speed-increasing gearbox, which significantly improves the generator speed and power generation efficiency.

[0078] Specifically, the speed-increasing gearbox in this embodiment is a speed-increasing planetary gearbox. The speed-increasing planetary gearbox can address the problems of low wave motion frequency and dispersed energy density, thereby ensuring that the generator can continue to generate electricity efficiently under typical sea conditions.

[0079] In this embodiment, the connecting part is a connecting flange 110. One end of the speed-increasing gearbox is connected to the connecting flange 110, and the other end is connected to the drive shaft of the generator.

[0080] In this embodiment, the connecting flange 110 is a standard structure, which has better structural strength after connection, thereby ensuring a stable connection between the speed-increasing gearbox and the floating frame 100 in the box, and thus transmitting torque and resisting vibration and impact loads in the marine environment.

[0081] One end of the speed-increasing planetary gearbox is connected to the connecting flange 110, and the other end is connected to the drive shaft of the generator, thus stabilizing the transmission chain and achieving excellent transmission efficiency. At the same time, the flange connection method facilitates the installation and maintenance of the speed-increasing gearbox and supports modular replacement, reducing operating and maintenance costs.

[0082] In this embodiment, the hinged end is a fork arm structure 330.

[0083] Furthermore, the fork arm structure 330 has a splined shaft 331. The drive shaft of the generator is connected to the splined shaft 331 so that the dual-shaft generator can rotate circumferentially along the splined shaft 331.

[0084] Specifically, the fork arm structure 330 with splined shaft 331 is connected to the drive shaft of the dual-shaft generator, thereby ensuring the reliability, alignment, and resistance to off-center loads of power transmission. The splined shaft 331 connection provides a large torque transmission capacity and multi-tooth meshing contact, effectively dispersing stress concentration and avoiding the risk of shear failure that may occur with keyed connections, making it particularly suitable for alternating load conditions in marine environments.

[0085] The fork arm structure 330 provides a stable support foundation for the spline shaft 331, ensuring the stability and coaxiality of the generator's drive shaft during circumferential rotation and reducing vibration and noise. Simultaneously, the spline connection allows for a certain degree of axial float, compensating for minor misalignments caused by manufacturing errors, thermal expansion and contraction, or wave loads, thus improving the system's adaptability and reliability.

[0086] In this embodiment, the wave power generation flexible cage also includes a mesh cover 500.

[0087] In this embodiment, both the float 100 and the buoyancy tube 311 in the cage are provided with support rods along their own extension direction. The net 500 is hung on the support rods and has a sinker at its bottom end to form a net cage below the float 100 and the float assembly 300 in the cage.

[0088] Specifically, in this embodiment, the net 500 has a net bottom, and the net 500 suspended on the support rod forms an aquaculture space in the net cage below the water surface. The support rod is arranged along the extension direction of the floating frame structure, providing multiple evenly distributed suspension points for the net 500, and can disperse the water flow impact force and biological load on the net 500, avoiding stress concentration and extending the service life of the net 500.

[0089] The bottom sinking mechanism uses gravity to fully unfold the netting 500 and maintain it in the preset net shape, ensuring the stability of the breeding volume, preventing the netting 500 from tangling, and promoting water exchange in the tank, thus providing a good growth environment for the cultured organisms.

[0090] In this embodiment, the mesh 500 includes a first mesh, a second mesh, and a third mesh.

[0091] The first net, the second net, and the third net are respectively positioned below the first float 310, below the container float 100, and below the second float 320 to form the first net compartment, the second net compartment, and the third net compartment, respectively.

[0092] Specifically, in this embodiment, the in-cabin float 100 adopts a rectangular design with four connecting parts at the four corners. The first float 310 and the second float 320 are symmetrically connected to the two connecting parts on both sides of the rectangle, respectively. With this structure, the power generation and transmission system are symmetrically distributed on both sides of the container, and the force is balanced, effectively avoiding structural off-center loading or abnormal wear caused by torque imbalance.

[0093] In addition, the structure of the four corner connections maximizes the distance between the connection points of the first float 310 and the second float 320 and the float 100 in the box, enhancing the torsional rigidity and stability of the overall structure, especially when encountering oblique wave impacts.

[0094] In this embodiment, the first net, the second net, and the third net are respectively located below the first floating frame 310, the in-box floating frame 100, and the second floating frame 320, forming three independent net compartments, thereby realizing the functional zoning of the aquaculture space.

[0095] Furthermore, each of the three net compartments can independently perform net hoisting, replacement, cleaning, or harvesting operations without affecting the normal operation of other net compartments, significantly reducing the complexity and time cost of maintenance operations. At the same time, the multi-compartment structure enhances the redundancy and risk resistance of the net cage system; even if one net compartment is damaged, the other net compartments can remain intact.

[0096] In this embodiment, the far ends of the first float 310 and the second float 320 are the lifting points of the two floats, and the midpoints of the two sides of the float 100 in the box that connect with the first float 310 and the second float 320 are the lifting points of the float 100 in the box.

[0097] When algae and shellfish attach to the netting after prolonged use, a crane can be used to connect the lifting points to lift the corresponding floating frame and the net compartment below the floating frame individually. This allows for drying, lifting, or cleaning of the nets to prevent attachment from affecting water exchange, increasing mooring force, and compromising mooring safety.

[0098] It should be noted that when a separate net compartment needs to be lifted, the generator can act as an electric motor to assist the ship's crane in lifting the middle part of the buoyancy tube 311 of the bow or stern floating frame, raising the net 500 3-5m above the water surface for drying and washing operations.

[0099] In this embodiment, the floating frame 100 in the container forms a tower 120. A power source electrically connected to a plurality of generators is provided on the tower 120.

[0100] Specifically, in this embodiment, a tower 120 is installed on the floating frame 100 in the cage, and multiple generators are electrically connected to the power source on the tower 120, realizing the integrated and optimized management of power generation, energy storage and power distribution systems, and improving the energy autonomy and operational reliability of the entire wave power generation flexible cage.

[0101] In this embodiment, the tower is positioned at a high level of 120 meters to keep the power supply (battery pack, distribution cabinet, etc.) away from the wave splash zone and seawater corrosion environment, which greatly improves the safety, durability and maintainability of the electrical equipment.

[0102] It should be noted that in this embodiment, the cable connectors used to connect the power supply and the generator, as well as the motor, all meet the IP67 waterproof rating.

[0103] The power supply is centrally located on tower 120, facilitating unified storage, management, and distribution of electricity generated by multiple generators. This not only optimizes space utilization but also simplifies wiring layout and reduces power transmission losses. Furthermore, it provides a stable and reliable power supply for monitoring equipment, feeding systems, communication devices (such as radar and antennas), and potential tourism facilities installed on the wave-powered flexible net cages, reducing reliance on shore power or diesel generators and aligning with the green and low-carbon development direction of deep-sea aquaculture.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
