Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture equipment technology, and in particular to a deep-sea aquaculture cage that is resistant to wind, waves and ocean currents. Background Technology

[0002] With the continuous expansion of aquaculture scale, 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 current-receiving area, resulting in poor current resistance; the ocean currents have a large angle of attack on the cages; and fixed anchoring systems are prone to failure under extreme sea conditions. Utility Model Content

[0004] Therefore, there is a need to provide a deep-sea aquaculture cage that is resistant to wind, waves and currents, in order to solve the problems of poor current resistance caused by the large current-receiving area of ​​the existing circular or square structure, and the easy failure of the fixed anchoring system under extreme sea conditions.

[0005] To achieve the above objectives, this utility model provides a deep-sea wind, wave and current resistant aquaculture cage, including 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 chamber, radial support rings, a mesh surface, and a conical guide. There are two or more radial support rings arranged in an array. The axial support chamber spans multiple radial support rings. The axial support chamber and radial support rings are hollow structures. The mesh surface is set on the axial support chamber and radial support chamber. The conical guide is set at both ends of the axial support chamber, forming a breeding space inside the conical guide and inside the mesh surface.

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

[0008] The power generation device is mounted on a conical guide tube and includes blades and a generator. The blades are connected to the generator housing. The generator has a rotating shaft, and 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 gabion body.

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

[0010] Unlike existing technologies, the above technical solution has the following advantages: By setting up axial support chambers and radial support rings for the net cage body, in conjunction with the net surface and conical guide fluid, an aquaculture space is formed. At the same time, the resistance of water flow in both directions of the net cage body when it is submerged in water is reduced by relying on the horizontally set conical guide fluid, which reduces the swaying of the anchoring device. The pump body exchanges gas and liquid through pipelines for at least one structure of the axial support chamber and radial support ring, which enables the net cage body to descend or float, and to rotate the net cage body, which facilitates the adjustment of the aquatic product accumulation position and cleaning, and adapts to the aquatic product aquaculture environment or sea conditions. The power generation device can use the water flow guided by the conical guide fluid and the external force of the liquid flow direction under the water surface to store and provide electricity, and can perform electrical control operation.

[0011] In a preferred embodiment of this application, the mooring device includes a fixed anchor and a mooring cable. The fixed anchor is connected to the seabed, and one end of the mooring cable is connected to the fixed anchor, while the other end is connected to the cage body. By setting up the fixed anchor and mooring cable, it is convenient to position the cage body on the seabed.

[0012] In a preferred embodiment of this application, the mooring device further includes chains connected to both ends of a mooring cable, which is connected to a fixed anchor and the seabed via the connection at both ends. The weight of the steel chains at both ends increases the anchoring capacity and tension, preventing insufficient cable tension from tangling with the blades of the power generation device and avoiding knots in the cables themselves.

[0013] In a preferred embodiment of this application, the radial support ring includes an inner ring, an outer ring, and an axial connector. The axial connector connects the inner ring and the outer ring. The axial support pod passes between the inner ring and the outer ring and is connected to the axial connector. Arranging two or more radial floats axially increases the rigidity of the gabion frame ring. A pipe connection between the radial support ring and the axial connector forms a unified adjustable float. Air inlets and outlets and seawater inlets and outlets are provided on the radial support ring to facilitate the unified movement of gas and liquid.

[0014] In a preferred embodiment of this application, the system further includes a gabion intermediate shaft, which is connected to a conical guide via a flange. The power generation device is also connected to the conical guide via the gabion intermediate shaft. The intermediate shaft facilitates support and anchoring of the overall structure and allows for easy installation of the engine shaft end of the power generation device.

[0015] In a preferred embodiment of this application, the mooring devices are located at both ends of the gabion body, with one or more mooring devices at each end. When multiple anchors are used, the connection directions of two or more mooring devices at each end to the gabion body are arranged at an angle. By arranging the connection directions of two or more mooring devices at each end to the gabion body at an angle, the positioning effect of the gabion body in the water is ensured, and the external force of occasional lateral water flow is limited.

[0016] In a preferred embodiment of this application, the cage body further includes a sliding cage door, which is connected to the mesh surface or axial support chamber via a slide rail. This facilitates the opening of inlet and outlet doors, allowing for the safe entry and exit of feed, personnel, equipment, and aquaculture organisms. During the aquaculture process, some doors can be opened or closed as needed to adjust the water flow within the cage.

[0017] In a preferred embodiment of this application, the pump body includes an air pump, or an air pump and a liquid pump. By connecting the air pump and the liquid pump to the distribution valve pipeline, and the distribution valve having multiple output ends, the output ends are respectively connected to the hollow structure pipelines of each axial support chamber, facilitating the communication between the hollow structures of the axial support chambers and the radial support rings of the cage body for gas-liquid exchange.

[0018] In a preferred embodiment of this application, the mooring device further includes a surface float connected to the net cage body via a rope and positioned on the water surface above the net cage body. This allows for the installation of the controller, battery, pipelines, and pump. Furthermore, when the net cage body is submerged, the length of the rope connecting the surface float and the net cage body limits the submersion depth of the net cage body, preventing excessive submersion that could negatively impact the survival of aquatic products due to inaccurate gas-liquid exchange, abnormal ocean currents, or operational errors.

[0019] In a preferred embodiment of this application, the mesh surface is a plate with openings. By setting the plate with openings as the mesh surface structure, it is easier to reduce the disturbance resistance generated by the water flow on the plate surface, avoid the net cage body being pulled by the water flow, thus increasing the stress on the anchoring device, and reduce the flow rate of water into the net cage body, thereby preventing the farmed organisms or aquatic products from continuously resisting the water flow.

[0045] Please refer to the following: Figures 1 to 5 A deep-sea wind, wave and current resistant aquaculture cage includes 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 chamber 11, a radial support ring 12, a mesh surface 13, and a conical guide 14. There are two or more radial support rings 12 arranged in an arrangement. The axial support chamber 11 spans multiple radial support rings 12. The axial support chamber 11 and the radial support rings 12 are hollow structures. The mesh surface 13 is disposed on the axial support chamber 11 and the radial support chamber. The conical guide 14 is disposed at both ends of the axial support chamber 11, and forms a breeding space inside the conical guide 14 and inside the mesh surface 13.

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

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

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

[0050] Based on the above structure, during the assembly of the deep-sea wind, wave, and current resistant aquaculture cage, the radial support ring 12 is placed on the ground. Pipe fixing rings or clamps are then assembled on the radial support ring 12. The pipe fixing rings or clamps can be arranged in a staggered manner, or by welding, binding, or locking two pipe fixing rings or two sets of clamps, thus achieving mutual assembly and fixation of the radial support ring 12 and the axial support chamber 11 at the positions of the pipe fixing rings or clamps. After assembling the radial support rings 12 and assembling the pipe fixing rings, each radial support ring 12 is lifted, and each axial support chamber 11 is assembled around each radial support ring 12 using pipe fixing rings or clamps, forming a columnar frame structure in the middle of the cage body 10. The spacing between each axial support chamber 11 is adjusted, and the pipe fixing rings or clamps are fixed, completing the columnar frame structure in the middle of the cage body 10.

[0051] Subsequently, the conical guide 14 is assembled to both ends of the columnar frame structure in the middle of the cage body 10 by welding, binding, or setting flanges to lock the conical guide 14 and the axial support chamber 11, so that the conical guide 14 at both ends of the cage body 10 is formed.

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

[0053] Then, the pump body 20 and the distribution valve 30 are installed. The pump body 20 and the distribution valve 30 are connected by pipeline. The multiple output ends of the distribution valve 30 are connected to each axial support chamber 11 respectively. Openings or one-way valves are preset on the axial support chamber 11 to realize gas-liquid exchange.

[0054] Subsequently, the power generation device 50 is installed. The generator 52 of the power generation device 50 is mounted on the space reserved at the end of the conical guide 14 via one end of the rotating shaft. The blades 51 are connected to the housing of the generator 52, and the power output terminal of the generator 52 is connected to a control module or battery that is preset inside the net cage body 10 or preset on the water surface via a buoy through a wire. In other embodiments, when the net cage body is provided with a net cage intermediate shaft 18, one end of the rotating shaft of the generator 52 is connected to the net cage intermediate shaft 18.

[0055] The entire equipment is then towed to a designated body of water. The generator 52 of the power generation device 50 is connected to the anchoring device 40, and the shaft of the generator 52 is used to position the cage body 10. The pump body 20 is then operated to exchange gas and liquid within the axial support chamber 11, enabling it to rise, fall, or rotate in the water.

[0056] Aquatic products are placed in the deep-sea, wind- and wave-resistant aquaculture cages after installation and they are submerged to a specific water depth for aquaculture. During the aquaculture process, the water flow impacts the conical guide 14, which reduces 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 and floats within a certain limited range in the water. Part of the diverted water reaches the blades 51 of the generator housing connected to the generator device 50. The blades 51 drive the housing of the generator 52 to rotate relative to the rotating shaft of the generator 52, driving the generator device 50 to supply power to external or internal electrical appliances or energy storage batteries, thereby powering or charging underwater equipment or floating electrical control equipment and power sources. By setting up axial support chambers 11 and radial support rings 12 in the net cage body 10, along with the net surface 13 and conical guide fluid 14, a breeding space is formed. At the same time, the horizontally arranged conical guide fluid 14 reduces the resistance of water flow at both ends of the net cage body 10 when it is submerged in water, reducing the swaying of the anchoring device 40 when it is fixed. The pump body 20 performs gas-liquid exchange in at least one of the structures in the axial support chambers 11 and radial support rings 12, causing the net cage body 10 to descend or float, and also allows for rotation of the net cage body 10 for easy adjustment. When the aquatic products are piled up at a location where the radial support ring of the net cage body is several meters or more, the attachment environment of non-aquatic organisms attached to the outside of the net cage body is changed, such as by changing the temperature, water pressure and light intensity, so that they leave, die or fall off. This also facilitates the cleaning of the net cage body 10 by personnel above the water surface, adapting it to the aquatic product farming environment or sea conditions. The power generation device 50 can use the water flow guided by the conical guide 14 and the external force of the liquid flow direction below the water surface to store and provide electricity, and can perform electrical control operation.

[0057] In the above embodiment, to ensure that the rotating shaft of the generator 52 of the power generation device 50 has sufficient strength to connect the cage body 10 and the mooring device 40, the cross-sectional dimensions of the generator 52 rotating shaft can be thickened, and a stator and rotor are provided on the rotatable shaft and the generator 52 housing, so that the blades 51 drive the generator 52 housing to rotate, realizing the power generation function, and keeping the rotating shaft relatively stationary. The fixing force of the mooring device 40 is transmitted through the other end of the rotating shaft to the end of the rotating shaft connected to the cage body 10, thereby restricting the position of the cage body 10. This achieves a power generation method in which the rotating shaft is relatively stationary, and the blades 51 drive the generator 52 housing to rotate.

[0058] Please refer to the following: Figures 1 to 5In a preferred embodiment of this 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 one end of the mooring cable 42 is connected to the fixed anchor 41, while the other end is connected to the lifting assembly. By setting the fixed anchor 41 and the mooring cable 42, it is convenient to position the cage body 10 on the seabed. The fixed anchor can be a suction anchor, a gravity anchor, or a drag anchor.

[0059] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the mooring device 40 further includes a chain connected to both ends of the mooring cable 42. The mooring cable 42 is connected to the fixed anchor 41 and the seabed through the connection at both ends. By setting the chain, the mooring cable 42 is connected to the fixed anchor 41 and the cage body 10 at both ends. This allows the weight of the chain to keep the mooring cable 42 and the chain in a drooping state when in the water, preventing the water flow from winding up the mooring cable 42 and causing it to become entangled on the blade 51 or the fixed anchor 41.

[0060] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this 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 pod 11 passes between the inner ring 16 and the outer ring 15 and is connected to the axial connector 17. The axial connector 17 can be a fixing ring or a clamp, and has three fixing positions. Arranging two or more radial floats axially increases the ring stiffness of the gabion frame. The radial support ring 12 and the axial connector 17 are connected by pipes to form a unified adjustable float. The radial support ring 12 is provided with air inlet and outlet ports and seawater inlet and outlet ports to facilitate the unified movement of gas and liquid.

[0061] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, a net cage intermediate shaft 18 is further included. The intermediate shaft 18 is connected to the tapered guide 14 via a flange, and a separate flange is provided to connect it to the rotating shaft of the generator 52. The intermediate shaft 18 facilitates support of the overall structure and allows the generator 50 to be easily mounted on the net 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 net cage body via the intermediate shaft 18.

[0062] Please refer to the following: Figures 1 to 5In a preferred embodiment of this application, the mooring devices 40 are disposed at both ends of the net cage body 10, with two or more mooring devices 40 at each end of the net cage body 10, and the connection direction of the two or more mooring devices 40 at each end is set at an angle to the connection direction of the net cage body 10. By setting the connection direction of the two or more mooring devices 40 at each end at an angle to the connection direction of the net cage body 10, it is easier to ensure the positioning effect of the net cage body 10 in the water and to limit the external force of occasional lateral water flow. Specifically, the angle between the connection direction of the two or more mooring devices 40 and the connection direction of the net cage body 10 is in the range of 10 degrees to 20 degrees, and the angle can be 10 degrees, 12 degrees, 15 degrees, 17 degrees or 20 degrees.

[0063] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the cage body 10 further includes a sliding cage door 19. The sliding cage door 19 is connected to the mesh surface 13 or the axial support chamber 11 via a slide rail between the two axial support chambers 11. This facilitates the opening of inlet and outlet doors, allowing for the safe entry and exit of feed, personnel, equipment, and aquaculture organisms. During the aquaculture process, some doors can be opened or closed as needed to adjust the water flow rate inside the cage.

[0064] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, it further includes an air pump and a distribution valve 30, or an air pump, a liquid pump, and a distribution valve 30. The air pump and liquid pump are connected to the distribution valve 30 via pipelines. The distribution valve 30 has multiple output ends, which are respectively connected to the hollow structure pipelines of each axial support chamber 11. By setting the air pump and liquid pump connected to the distribution valve 30 via pipelines, and the distribution valve 30 having multiple output ends, which are respectively connected to the hollow structure pipelines of each axial support chamber 11, it is convenient to connect the hollow structures of the axial support chambers 11 and the radial support rings 12 of the net cage body 10 for gas-liquid exchange. However, when using an air pump, air can be injected by pumping air during buoyancy, and air can be vented by opening the external vent hole during descent, relying on the weight of the net cage body to fill in water and sink.

[0065] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the tapered guide 14 has a length-to-diameter ratio of 3:2 and streamlined shape with cone angles less than 37 degrees at both ends. This reduces the surface area of ​​the gabion facing the current.

[0066] In the above embodiments, the tapered fluid guide surface can be covered with plastic or metal skin and assembled with an internally preset tubular skeleton.

[0067] In the above embodiments, the axial support chamber or radial support ring can be fixed to the flange through a prefabricated assembly structure and assembled with another flange pre-connected to the tapered guide. The flange can be provided with through holes for adapting to the intermediate shaft of the gabion or with a size larger than the intermediate shaft of the gabion.

[0068] Please refer to the following: Figures 1 to 5 In a preferred embodiment of this application, the axial support chambers 11 are evenly distributed along the length of the radial support rings 12.

[0069] In the above embodiments, in addition to using a rope chain structure for raising and lowering the anchoring device, multiple sections of hinged rods can also be used, and universal joints can be used to connect the cage body to achieve connection and limiting.

[0070] In the above embodiments, the mesh surface 13 has a multi-layer structure, which can be a structure made of flexible material, or at least one of the following structures formed by perforating metal or plastic plates. By setting perforated plates as the mesh surface structure, it is easier to reduce the disturbance resistance generated by water flow on the plate surface, avoid the net cage body being pulled by the water flow, increase the stress on the anchoring device, and reduce the flow rate of water into the net cage body, thus preventing aquatic products from continuously resisting the water flow.

[0071] In the above embodiments, in order to facilitate the installation of equipment on the water surface and to make it easier for operators to find the assembly position of the net cage body 10, the mooring device 40 also includes a water surface float 43. The water surface float 43 is connected to the net cage body 10 by a rope and is set on the water surface above the net cage body 10. This allows for the installation of the controller, battery, pipeline and pump body 20. In the state where the net cage body 10 is submerged, the length of the rope connecting the water surface float 43 and the net cage body 10 limits the diving depth of the net cage body 10. This avoids the problem of the net cage body sinking too deep and affecting the survival of aquatic products in the event of inaccurate gas-liquid exchange, abnormal ocean currents or operational errors.

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

[0073] In the above embodiments, the generator 52 may be a horizontal shaft propeller worm gear machine.

[0074] In the above embodiments, the conical fluid guide 14 can be formed into a cone-shaped frame by bending the axial support chamber 11 or by welding, gluing, fusion welding or connecting the components through a separate structure, and the attached surface covering plate is used for drainage treatment.

[0075] In the above embodiment, the mooring cable 42 is connected by a composite mooring cable 42, that is, the two ends are made of steel anchor chains and the middle section is made of flexible cable. The two ends of the steel anchor chains are respectively connected to the fixed anchor 41 and the cage body 10. The anchoring capacity and tension are increased by the self-weight of the two ends of the steel anchor chains, avoiding tangling and knotting caused by insufficient cable tension.

[0076] In the above embodiments, in order to achieve power output while the engine housing is rotating, the power output terminal can use at least one of the following structures: slip ring and brush, brushless excitation device, commutator and brush, or slip ring assembly to achieve power output.

[0077] In the above embodiment, the power output of generator 52 is stored in the energy storage battery pack through charging, and then provided with regulated power to the electrical equipment through an inverter and a voltage regulator. This enables the connection and utilization of unstable hydroelectric power generation and avoids the voltage instability problem caused by different ocean currents when the horizontal axis generator 52 is subjected to water flow.

[0078] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
