Description

Technical Field

[0001] The present invention relates to the technical field of marine aquaculture equipment, and in particular to a deep-sea, wind-wave-resistant and ocean-current-resistant aquaculture cage. Background Art

[0002] With the continuous expansion of aquaculture, aquaculture equipment has developed from saturated nearshore areas to deep sea areas.

[0003] However, traditional deep-sea cages have the following technical defects: the existing circular or square structures have a large flow-receiving area, resulting in poor current resistance, the ocean current has a large angle of attack on the cage, and the fixed mooring system is prone to failure under extreme sea conditions. Summary of the Invention

[0004] To this end, it is necessary to provide a deep-sea aquaculture cage that is resistant to wind, waves and currents to solve the problems in the existing technology that the circular or square structure has a large flow-receiving area resulting in poor flow resistance and the fixed mooring system is prone to failure under extreme sea conditions.

[0005] To achieve the above-mentioned purpose, the present invention provides a deep-sea wind, wave and current resistant aquaculture cage, comprising a cage body, a pump body, a distribution valve, an anchoring device and a power generation device;

[0006] The cage body includes an axial support cabin, a radial support ring, a mesh surface, and a conical guide body. The radial support rings are arranged in an array of two or more. The axial support cabin is arranged across the plurality of radial support rings. The axial support cabin and the radial support ring are hollow structures. The mesh surface is arranged on the axial support cabin and the radial support cabin. The conical guide body is arranged at both ends of the axial support cabin, and a breeding space is formed inside the conical guide body and the mesh surface.

[0007] The pump body is connected to the distribution valve pipeline, and the distribution valve is provided with multiple output ends, and the output ends are connected to the hollow structure pipeline of at least one structure of the axial support cabin and the radial support ring;

[0008] The power generation device is arranged on the conical guide body, and includes blades and a generator. The blades are connected to the generator housing. The generator is provided with a rotating shaft. The generator housing rotates relative to the rotating shaft. The rotating shaft passes through the generator housing, and one end of the rotating shaft is connected to the cage body.

[0009] One end of the anchoring device is connected to the seabed, and the other end of the anchoring device is connected to the other end of the rotating shaft of the generator of the power generation device.

[0010] Different from the existing technology, the above technical solution has the following advantages: by setting the axial support cabin and radial support ring of the cage body, cooperating with the mesh surface and the conical guide body, a breeding space is formed. At the same time, relying on the transversely arranged conical guide body, the resistance of the water flow in the two ends of the cage body when submerged in the water can be reduced, and the swing of the anchoring device when fixed can be reduced. The pump body performs gas-liquid exchange of at least one structure in the axial support cabin and the radial support ring through the pipeline, and performs the lowering or floating of the cage body, and rotates the cage body, which is convenient for adjusting the stacking position of aquatic products, and is convenient for cleaning and adaptation to the aquatic product breeding environment or sea conditions. The power generation device can use the water flow guided by the conical guide body and the external force of the liquid flow under the water surface to store and provide electricity, and can perform electronic control operations.

[0011] As a preferred embodiment of the present application, the mooring device includes a fixed anchor and a mooring cable, wherein the fixed anchor is connected to the seabed, and one end of the mooring cable is connected to the fixed anchor and the other end is connected to the cage body. The provision of the fixed anchor and the mooring cable facilitates positioning of the cage body on the seabed.

[0012] In a preferred embodiment of the present application, the mooring device further comprises a chain connected to both ends of a mooring cable, which is connected to a fixed anchor and the seabed via the connection between the two ends. The deadweight of the steel chains at both ends increases anchoring capacity and tension, preventing insufficient cable tension from causing entanglement with the blades of the power generation device and preventing the cable from becoming tangled.

[0013] As a preferred embodiment of the present application, the radial support ring includes an inner ring, an outer ring, and an axial connector. The axial connector connects the inner and outer rings, and the axial support chamber passes between the inner and outer rings and is connected to the axial connector. Arranging two or more radial buoyancy chambers axially increases the rigidity of the cage frame ring. A pipe connects the radial support ring and the axial connector to form a unified adjustable buoyancy chamber. The radial support ring is provided with air and seawater inlets and outlets to facilitate the unified movement of gas and liquid.

[0014] A preferred embodiment of the present application further includes a cage intermediate shaft, which is connected to the conical guide body via a flange. The generator is also connected to the conical guide body via the cage intermediate shaft. The cage intermediate shaft facilitates support and anchoring of the overall structure and facilitates installation of the generator engine shaft end.

[0015] As a preferred embodiment of the present application, the anchoring devices are installed at both ends of the cage body, with at least one anchoring device at each end. When multiple anchors are used, the two or more anchoring devices at each end are arranged at an angle to the direction of connection with the cage body. By arranging the two or more anchoring devices at each end at an angle to the direction of connection with the cage body, the cage body is effectively positioned in the water and the external force caused by occasional lateral water flow is limited.

[0016] In a preferred embodiment of the present application, the cage body further includes sliding doors connected to the mesh surface or axial support compartment via slide rails. These doors facilitate the opening of entry and exit doors, facilitating the safe entry and exit of feed, personnel, equipment, and cultured organisms. During the culture process, these doors can be opened and closed as needed to adjust the water flow within the cage.

[0017] As a preferred embodiment of the present application, the pump body includes an air pump, or an air pump and a liquid pump. The air pump and the liquid pump are connected to the distribution valve pipeline. The distribution valve has multiple output ports, each of which is connected to the hollow structure pipelines preset in each axial support cabin. This facilitates the communication between the axial support cabin and the hollow structure of the radial support ring of the cage body for gas-liquid exchange.

[0018] As a preferred embodiment of the present application, the mooring device further includes a surface float connected to the cage body via a cable and positioned above the water surface. This allows for installation of a controller, battery, piping, and pump. Furthermore, when the cage body is submerged, the length of the cable connecting the surface float to the cage body limits the cage's submergence depth, preventing the cage from sinking too deep and potentially impacting the survival of aquatic products due to inaccurate gas-liquid exchange, abnormal ocean currents, or operational errors.

[0019] In a preferred embodiment of the present application, the mesh surface is a plate with openings. By providing the perforated plate as the mesh surface structure, the disturbance resistance generated by the water flow is reduced on the plate surface, preventing the cage body from being pulled by the water flow and increasing the stress on the anchoring device. Furthermore, the flow rate of water flowing into the cage body is reduced, preventing the cultured organisms or aquatic products from continuously resisting the water flow.

[0045] Please also refer to Figures 1 to 5 A deep-sea wind, wave and current resistant aquaculture cage comprises a cage body 10, a pump body 20, a distribution valve 30, an anchoring device 40 and a power generation device 50;

[0046] The cage body 10 includes an axial support cabin 11, a radial support ring 12, a mesh surface 13 and a conical guide body 14. The number of the radial support rings 12 is more than two and they are arranged in an array. The axial support cabin 11 is arranged across multiple radial support rings 12. The axial support cabin 11 and the radial support ring 12 are hollow structures. The mesh surface 13 is arranged on the axial support cabin 11 and the radial support cabin. The conical guide body 14 is arranged at both ends of the axial support cabin 11 and forms a breeding space inside the conical guide body 14 and inside the mesh surface 13.

[0047] The pump body 20 is connected to the distribution valve 30 through a pipeline. The distribution valve 30 is provided with a plurality of output ends, and the output ends are connected to the hollow structure pipeline of at least one structure of the axial support cabin 11 and the radial support ring 12;

[0048] The power generation device 50 is arranged on the conical guide body 14, and includes blades 51 and a generator 52. The blades 51 are connected to the outer shell of the generator 52. The generator 52 is provided with a rotating shaft. The shell of the generator 52 rotates relative to the rotating shaft. The rotating shaft passes through the shell of the generator 52, and one end of the rotating shaft is connected to the cage body 10.

[0049] One end of the anchoring device 40 is connected to the seabed, and the other end of the anchoring device 40 is connected to the other end of the rotating shaft of the generator 52 of the power generation device 50.

[0050] According to the above structure, during the assembly process of the deep-sea wind, wave and current resistant aquaculture cage, the radial support ring 12 is placed on the ground, and a pipe fixing ring or a splint is assembled on the radial support ring 12. The pipe fixing ring or the splint can be in a staggered manner, or two pipe fixing rings or two groups of splints can be welded, tied or locked to achieve the mutual assembly and fixation of the radial support ring 12 and the axial support cabin 11 at the position of the pipe fixing ring or the splint. After the radial support ring 12 and the assembled pipe fixing ring are assembled, each radial support ring 12 is hoisted, and each axial support cabin 11 is assembled around each radial support ring 12 through the pipe fixing ring or the splint to form a columnar frame structure in the middle of the cage body 10. The spacing between each axial support cabin 11 is adjusted and the pipe fixing ring or the splint is fixed to complete the structure of the columnar frame structure in the middle of the cage body 10.

[0051] The conical guide body 14 is then assembled at both ends of the columnar frame structure in the middle of the cage body 10 by welding, bundling or setting flange locks at both ends of the conical guide body 14 and the axial support cabin 11, so that the conical guide body 14 at both ends of the cage body 10 is formed.

[0052] After the conical guide body 14 is assembled, the multi-layer mesh 13 is covered on the outside of the conical guide body 14 and the axial support cabin 11, and some equipment installation space is reserved at the ends of the conical guide body 14 at both ends. The edges of the mesh 13 are sealed with the conical guide body 14.

[0053] Then the pump body 20 and the distribution valve 30 are installed. The pump body 20 is connected to the distribution valve 30 through pipelines. The multiple output ends of the distribution valve 30 are respectively connected to each axial support cabin 11, and openings or one-way valves are preset on the axial support cabin 11 to achieve gas-liquid exchange.

[0054] Next, the power generation device 50 is installed. The generator 52 of the power generation device 50 is mounted on one end of its rotating shaft in the space reserved at the end of the tapered guide body 14. The blades 51 are connected to the housing of the generator 52. The power output of the generator 52 is connected via a wire to a control module or battery located within the cage body 10 or on the surface via a buoy. In other embodiments, if the cage body is provided with an intermediate shaft 18, one end of the rotating shaft of the generator 52 is connected to the intermediate shaft 18.

[0055] The entire device is then towed to a designated body of water, connected to the rotating shaft of the generator 52 of the power generation device 50 via the anchoring device 40, and the cage body 10 is positioned along with the rotating shaft. The pump 20 is then operated to exchange gas and liquid within the axial support chamber 11, allowing the cage to be raised, lowered, or rotated in the water.

[0056] Aquatic products are put into the installed deep-sea wind, wave and current resistant aquaculture cages and sunk to a specific water depth for aquaculture. During the aquaculture process, the water flow impacts the conical guide body 14 and is drained to reduce the impact force. Under the position limitation of the anchoring device 40, the cage body 10 is connected to the large-sized rotating shaft of the generator 52, floating within a certain limited range in the water, and the drained water reaches the blades 51 connected to the generator shell of the power generation device 50. The blades 51 drive the shell of the generator 52 to rotate relative to the rotating shaft of the generator 52, driving the power generation device 50 to supply power to external or built-in electrical appliances or energy storage batteries, so as to supply power or charge underwater equipment or electronic control equipment and power supplies floating on the water surface. By setting the axial support cabin 11 and radial support ring 12 of the cage body 10, cooperating with the net surface 13 and the conical guide body 14, a breeding space is formed. At the same time, the conical guide body 14 arranged laterally can reduce the resistance of the water flow in both directions of the cage body 10 when it is submerged in the water, reduce the swing of the anchoring device 40 when it is fixed, and the pump body 20 performs gas-liquid exchange in at least one structure of the axial support cabin 11 and the radial support ring 12, and performs the descent or buoyancy of the cage body 10, as well as the rotation of the cage body 10, which is convenient for adjustment. At the accumulation position of aquatic products, when the size of the radial support ring of the cage body is more than several meters, the attachment environment of non-aquatic product organisms attached to the outside of the cage body is changed, such as changes in temperature, water pressure and light intensity, so that they leave, die or fall off, and it is convenient for personnel to clean the cage body 10 above the water surface, adapt to the aquatic product breeding environment or sea conditions, and the power generation device 50 can use the water flow guided by the direction of the conical guide body 14 and the external force of the liquid flow under the water surface to store and provide electricity, so as to perform electronic control operations.

[0057] In the above embodiment, to ensure sufficient strength for the shaft of the generator 52 of the power generation device 50 to connect to the cage body 10 and the anchoring device 40, the cross-sectional dimensions of the generator 52 shaft are thickened. A stator and rotor are positioned on the rotatable shaft and the generator 52 housing. This allows the blades 51 to rotate the generator 52 housing, achieving power generation while maintaining the shaft relatively stationary. The anchoring force of the anchoring device 40 is transmitted through the other end of the shaft to the end connected to the cage body 10, thereby restricting the position of the cage body 10. This achieves a power generation method in which the shaft remains relatively stationary while the blades 51 rotate the generator 52 housing.

[0058] Please also refer to Figures 1 to 5As a preferred embodiment of the present application, the mooring device 40 includes a fixed anchor 41 and a mooring cable 42. The fixed anchor 41 is connected to the seabed, and the mooring cable 42 is connected to the fixed anchor 41 at one end and to the lifting assembly at the other end. The provision of the fixed anchor 41 and mooring cable 42 facilitates positioning of the cage body 10 on the seabed. The fixed anchor can be a suction anchor, a gravity anchor, or a drag anchor.

[0059] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the mooring device 40 further includes a chain connected to both ends of a mooring line 42. The mooring line 42 is connected to the fixed anchor 41 and the seabed through the communication between the two ends. By providing a chain, the mooring line 42 is connected to the fixed anchor 41 and the cage body 10 at both ends. When in water, the weight of the chain ensures that the mooring line 42 and the chain are in a drooping state, preventing the mooring line 42 from being rolled up by the water and causing it to be entangled with the blades 51 or the fixed anchor 41.

[0060] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the radial support ring 12 includes an inner ring 16, an outer ring 15 and an axial connector 17. The axial connector 17 connects the inner ring 16 and the outer ring 15. The axial support cabin 11 passes through the inner ring 16 and the outer ring 15 and is connected to the axial connector 17. The axial connector 17 can be a fixed ring or a splint, and is provided with three fixed positions. Arranging two or more radial floating cabins axially increases the ring stiffness of the cage frame. The radial support ring 12 and the axial connector 17 are connected by a pipe to form a unified adjustable floating cabin. Air inlet and outlet ports and seawater inlet and outlet ports are provided on the radial support ring 12 to facilitate the unified movement of gas and liquid.

[0061] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the cage further includes an intermediate shaft 18, which is connected to the conical guide body 14 via a flange and is also flanged to the rotating shaft of the generator 52. The intermediate shaft 18 facilitates support of the overall structure and facilitates assembly of the generator 50 onto the cage body 10 via the intermediate shaft 18. With the intermediate shaft 18, one end of the rotating shaft of the generator 52 of the generator 50 is connected to the cage body by connecting to the intermediate shaft 18.

[0062] Please also refer to Figures 1 to 5As a preferred embodiment of the present application, the anchoring devices 40 are provided at both ends of the cage body 10. There are two or more anchoring devices 40 at each end of the cage body 10, and the two or more anchoring devices 40 at each end are arranged at an angle to the connection direction of the cage body 10. By arranging the two or more anchoring devices 40 at each end at an angle to the connection direction of the cage body 10, it is easy to ensure the positioning effect of the cage body 10 in the water and limit the external force of occasional lateral angle water flow. Specifically, the angle between the connection direction of the two or more anchoring devices 40 and the cage body 10 is in the range of 10 degrees to 20 degrees, and the angle can specifically be 10 degrees, 12 degrees, 15 degrees, 17 degrees, or 20 degrees.

[0063] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the cage body 10 further includes a sliding cage door 19, which is connected to the mesh surface 13 or the axial support compartments 11 via a slide rail, and is connected between the two axial support compartments 11. This facilitates the opening of entry and exit doors, facilitating the safe entry and exit of feed, personnel, equipment, and cultured organisms. During the culture process, some doors can be opened and closed as needed to adjust the water flow within the cage.

[0064] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, it further includes an air pump and a distribution valve 30, or an air pump, a liquid pump and a distribution valve 30, wherein the air pump and the liquid pump are connected to the distribution valve 30 by a pipeline, and the distribution valve 30 is provided with multiple output ends, which are respectively connected to the hollow structure pipelines preset in each axial support cabin 11. By providing an air pump and a liquid pump connected to the distribution valve 30 by a pipeline, the distribution valve 30 is provided with multiple output ends, which are respectively connected to the hollow structure pipelines preset in each axial support cabin 11, so as to facilitate the communication of the hollow structures of the axial support cabin 11 and the radial support ring 12 of the cage body 10 for gas-liquid exchange processing. However, when an air pump is used, air can be injected by pumping air through the air pump when floating up, and the external air vent can be opened to exhaust air when sinking, and the cage body relies on its own weight to fill with water and sink.

[0065] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the tapered guide body 14 is a streamlined guide body with a length-to-diameter ratio of 3:2 and a cone angle of less than 37 degrees at both ends, thereby reducing the frontal flow area of the cage.

[0066] In the above embodiment, the surface of the conical guide body can be covered with a plastic or metal skin and assembled with a preset tubular frame inside.

[0067] In the above embodiment, the axial support cabin or the radial support ring can be fixed to the flange through a prefabricated assembly structure and assembled with another flange pre-connected with the conical guide body. A through hole can be opened on the flange to adapt to the intermediate shaft of the cage or a through hole larger than the intermediate shaft of the cage.

[0068] Please also refer to Figures 1 to 5 As a preferred embodiment of the present application, the axial support compartments 11 are evenly distributed along the length direction of the radial support ring 12 .

[0069] In the above embodiment, in addition to using a rope chain structure to lift the mooring device, a plurality of mutually hinged rods can also be used, and a universal joint can be used to connect the cage body to achieve connection and limit processing.

[0070] In the above embodiment, the mesh surface 13 is a multi-layer structure, and can be made of a flexible material, or formed by punching holes in a metal or plastic plate. The use of a perforated plate as the mesh surface structure reduces the disturbance resistance generated by the water flow on the plate surface, preventing the cage body from being pulled by the water flow and increasing the stress on the anchoring device. It also reduces the flow rate of water into the cage body, preventing the aquatic product from continuously resisting the water flow.

[0071] In the above embodiment, in order to facilitate the installation of equipment on the water surface and to facilitate operators to find the assembly position of the cage body 10, the anchoring device 40 also includes a surface float 43, which is connected to the cage body 10 by a cable and is set on the water surface above the cage body 10, so that the controller, battery, pipeline and pump body 20 can be installed. When the cage body 10 is sinking, the length of the cable connecting the surface float 43 and the cage body 10 is used to limit the diving depth of the cage body 10, so as to avoid the problem that the cage body 10 sinks too deep due to inaccurate gas-liquid exchange, abnormal ocean current or operational error, which affects the survival of aquatic products.

[0072] In the above embodiment, in order to realize the convenient feeding of aquatic products, a feeder is provided on the water surface float 43 and is connected to the cage body 10 through a pipeline.

[0073] In the above embodiment, the generator 52 may be a horizontal-axis propeller turbine.

[0074] In the above embodiment, the conical guide body 14 can be formed into a vertebral frame by bending the axial support cabin 11 or setting up another structure for welding, gluing, welding or connecting with connectors, and a covering plate is provided on the surface for drainage treatment.

[0075] In the above embodiment, the mooring cable 42 is connected by a composite mooring cable 42, that is, the end sections at both ends are made of steel anchor chains, and the middle section is made of flexible cables. The steel anchor chains at both ends are respectively connected to the fixed anchor 41 and the cage body 10. The anchoring capacity and tension are increased by the dead weight of the steel anchor chains at both ends, thereby avoiding entanglement and knotting caused by insufficient tension of the cable.

[0076] In the above embodiment, in order to realize power output when the engine housing is rotating, the power output end can adopt at least one structure of slip ring and brush, brushless excitation device, commutator and brush or slip ring assembly to realize power output.

[0077] In the above embodiment, the power output of the generator 52 is stored in a battery pack through charging, and then provided to the electrical equipment through the inverter and voltage stabilizer. This allows for the connection and utilization of unstable power generation, avoiding the voltage instability problem caused by the horizontal axis generator 52 being exposed to varying ocean currents.

[0078] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection of the present invention. Therefore, based on the innovative concept of the present invention, changes and modifications to the embodiments described herein, or equivalent structural or equivalent process transformations made using the contents of the present invention's description and drawings, and direct or indirect application of the above technical solutions to other related technical fields, are all included in the scope of protection of the present invention's patent.
