Description

Technical Field

[0001] This invention relates to the field of deep-sea aquaculture technology, and in particular to an aquaculture cage. Background Technology

[0002] Cage aquaculture refers to a farming method that uses cages made of synthetic fibers, metal, or bamboo and wood materials, placed in open or semi-open waters such as lakes, reservoirs, bays, and nearshore areas. It utilizes natural water flow for water exchange, and intensively raises aquatic economic animals such as fish, shrimp, and shellfish within the cages. This aquaculture technology is characterized by its mobility, flexibility, simplicity, high yield, and wide adaptability to different water bodies. The cages are set in relatively large bodies of water, allowing water flow through the mesh. Uneaten feed and metabolic waste can be discharged outside the cages, creating a flowing water environment. This results in clean water with abundant dissolved oxygen, enabling high-density intensive farming. It also offers advantages such as simple management, fewer diseases, easy harvesting, and high yields.

[0003] With the rise of marine aquaculture, deep-sea aquaculture has also gradually developed. The deep-sea environment offers ample space for cage aquaculture, but the waves are much stronger. my country's coastal areas are frequently affected by typhoons, and traditional cage aquaculture systems cannot withstand typhoon attacks, easily resulting in severe losses. Improving the safety of deep-sea cage aquaculture remains a challenge. Summary of the Invention

[0004] The main objective of this invention is to propose an aquaculture cage that aims to improve the safety of aquaculture cages.

[0005] To achieve the above objectives, the aquaculture cage proposed in this invention comprises: The truss body includes a truss structure and a working platform. The truss body encloses and forms a ring structure. The working platform is connected to the truss structure. The working platform has a tower-like structure and has multiple compartments arranged along the height direction inside. A cage structure, comprising fasteners and a net, wherein the fasteners are spaced apart and connected to the bottom end of the truss body, and the net is connected to the fasteners to form a breeding space; The buoyancy system includes a buoy and a drainage system. The buoy is connected to the main body of the truss and has a water storage cavity inside. The drainage system can discharge water from the water storage cavity to control the draft of the main body of the truss.

[0006] In one embodiment, the pontoon is located at the bottom of the working platform.

[0007] In one embodiment, the work platform includes four, with the four corner points of the rectangle corresponding to each work platform distributed at intervals, and a connecting channel connecting adjacent work platforms to each other.

[0008] In one embodiment, each of the work platforms includes at least a first deck and a second deck along the height direction. The first deck corresponds to the top of the truss structure, and the second deck is located above the first deck. Both the first deck and the second deck are provided with connecting channels to connect two adjacent work platforms.

[0009] In one embodiment, the working platform is provided with a feed equipment compartment, and a feeding pipe extends from the feed equipment compartment. The feeding pipe is distributed on both sides of the connecting channel on the first deck to feed feed downwards.

[0010] In one embodiment, both the first deck and the second deck are surrounded by railings and equipped with lifesaving devices.

[0011] In one embodiment, the netting includes a top net, side nets, and a bottom net. The top net covers the bottom of the truss body, the side nets surround the outer perimeter of the net cage structure, and the upper and lower ends of the side nets are respectively connected to the top net and the bottom net. The top net, the side net, and the bottom net enclose the aquaculture space.

[0012] In one embodiment, the cage structure further includes a counterweight block connected to the bottom of the bottom net, which pulls the bottom net downward to form a cone-shaped net bag.

[0013] In one embodiment, the counterweight includes a plurality of counterweights, each of which is spaced apart along the extension direction of the bottom net, and each counterweight is stretched to form a conical net bag.

[0014] In one embodiment, a power generation component is provided at the top of the working platform, the power generation component including a wind turbine and a photovoltaic panel.

[0015] The technical solution of this invention proposes an aquaculture cage, belonging to the field of aquaculture equipment, suitable for large-scale fish and aquatic product farming in large waters such as oceans. It provides a stable growth space for aquatic products while facilitating feeding, inspection, and harvesting operations for staff, balancing farming efficiency and environmental adaptability. The aquaculture cage consists of a truss main body, a cage structure, and a floating system.

[0016] The truss structure of the main body is welded from galvanized steel pipes or aluminum alloy profiles, possessing high strength and corrosion resistance. The overall structure forms a ring, the shape of which can be circular, rectangular, or polygonal depending on the aquaculture environment and requirements, ensuring ample aquaculture space. In this embodiment, the truss structure is a ring-shaped rectangular structure; in other embodiments, the choice can be made according to actual needs. The working platform is constructed from anti-slip steel plates spliced ​​with a steel frame, and fixedly welded to the upper surface of the truss structure. The overall structure is tower-like, maximizing vertical space and minimizing horizontal footprint. Internally, partitions divide the space into multiple compartments arranged along the height, which can serve as feed storage compartments, equipment maintenance compartments, personnel rest compartments, etc., meeting different functional requirements. The fixing components of the net cage structure are flexible steel wire ropes, evenly spaced and connected to the bottom of the main truss body, ensuring uniform distribution of the fixing force on the netting. On the one hand, the steel wire rope has high tensile strength, ensuring sufficient strength and stability for the netting connection to the fixing components, preventing easy deformation. On the other hand, it can withstand the impact of ocean currents on the net cage structure, ensuring its stability in the water. The netting is made of high-strength polyethylene woven mesh or nylon mesh, which is wear-resistant and resistant to water flow impact. It is connected to the fixing components by binding or hooking, forming a closed aquaculture space that can accommodate a sufficient quantity of aquatic products. The floating system's pontoon is a sealed steel structure box, fixedly connected to the truss main body by brackets, forming a sealed water storage chamber inside. The volume of the water storage chamber is designed according to the overall weight and buoyancy requirements of the net cage.

[0017] The drainage system includes an air compressor, drain pipes, and control valves. The air compressor is installed inside the equipment compartment. One end of the drain pipe connects to the water storage chamber, and the other end extends to the outside of the net cage. The control valves control the opening and closing of the drain pipes. When the draft of the net cage needs to be adjusted, the air compressor is activated to drain the water from the water storage chamber, causing the truss main body and net cage structure to float upwards, reducing the draft. If the draft needs to be increased, the control valve is opened to allow water to flow into the water storage chamber by gravity. Through the regulation of the buoyancy system, the aquaculture net cage can adapt to different marine climates and water level changes. For example, when severe weather such as typhoons occurs at sea, the draft of the aquaculture net cage is increased to submerge it, reducing the height of the net cage above the sea surface, thereby improving the net cage's ability to resist typhoon attacks and ensuring its stability. After the typhoon ends, the water in the buoy is drained to submerge the net cage, maintaining a semi-submerged working state with the truss structure partially exposed above the water surface. This facilitates the normal work and activities of the staff on the truss main body. Attached Figure Description

[0029] Cage aquaculture refers to a farming method that uses cages made of synthetic fibers, metal, or bamboo and wood materials, placed in open or semi-open waters such as lakes, reservoirs, bays, and nearshore areas. It utilizes natural water flow for water exchange, and intensively raises aquatic economic animals such as fish, shrimp, and shellfish within the cages. This aquaculture technology is characterized by its mobility, flexibility, simplicity, high yield, and wide adaptability to different water bodies. The cages are set in relatively large bodies of water, allowing water flow through the mesh. Uneaten feed and metabolic waste can be discharged outside the cages, creating a flowing water environment. This results in clean water with abundant dissolved oxygen, enabling high-density intensive farming. It also offers advantages such as simple management, fewer diseases, easy harvesting, and high yields.

[0030] With the rise of marine aquaculture, deep-sea aquaculture has also gradually developed. The deep-sea environment offers ample space for cage aquaculture, but the waves are much stronger. my country's coastal areas are frequently affected by typhoons, and traditional cage aquaculture systems cannot withstand typhoon attacks, easily resulting in severe losses. Improving the safety of deep-sea cage aquaculture remains a challenge.

[0031] To solve the above problems, please refer to... Figure 1 and Figure 2This invention proposes an aquaculture cage 100, comprising a truss main body 1, a cage structure 2, and a floating system. The truss main body 1 includes a truss structure 11 and a working platform 12, which enclose a ring structure. The working platform 12 is connected to the truss structure 11 and has a tower-like structure with multiple compartments arranged along the height direction inside. The cage structure 2 includes fasteners 21 and netting 22. The fasteners 21 are connected at intervals to the bottom of the truss main body 1, and the netting 22 is connected to the fasteners 21 to form an aquaculture space. The floating system includes a buoy 3 and a drainage system. The buoy 3 is connected to the truss main body 1 and has a water storage chamber inside. The drainage system can discharge water from the water storage chamber to control the draft of the truss main body 1.

[0032] The present invention provides an aquaculture cage 100, belonging to the field of aquaculture equipment, suitable for large-scale fish and aquatic product farming in large waters such as oceans. It provides a stable growth space for aquatic products while facilitating feeding, inspection, and harvesting operations, balancing farming efficiency and environmental adaptability. The aquaculture cage 100 consists of a truss main body 1, a cage structure 2, and a floating system.

[0033] The truss structure 11 of the truss main body 1 is welded from galvanized steel pipes or aluminum alloy profiles, possessing high strength and corrosion resistance. It forms a ring-shaped structure, the shape of which can be circular, rectangular, or polygonal depending on the aquaculture environment and requirements, ensuring ample aquaculture space. In this embodiment, the truss structure 11 is a ring-shaped rectangular structure; in other embodiments, it can be selected according to actual needs. The working platform 12 is constructed from anti-slip steel plates and a steel frame, and is fixedly connected to the upper surface of the truss structure 11 by welding. It has a tower-like structure, which fully utilizes vertical space and reduces horizontal footprint. Internally, it is divided by partitions into multiple compartments arranged along the height direction. These compartments can serve as feed storage compartments, equipment maintenance compartments, personnel rest compartments, etc., meeting different functional requirements. The fixing components 21 of the net cage structure 2 are flexible steel wire ropes, evenly spaced and connected to the bottom of the truss main body 1, ensuring a uniform distribution of fixing force on the netting 22. On the one hand, the steel wire rope has high tensile strength, ensuring that the netting 22 connected to the fixing member 21 has sufficient strength and stability, and will not easily deform. On the other hand, it can also withstand the impact of ocean currents on the cage structure 2, ensuring the stability of the cage structure 2 in the water. The netting 22 is made of high-strength polyethylene woven mesh or nylon mesh, which has wear-resistant and water flow impact-resistant characteristics. It is connected to the fixing member 21 by binding or hooking to form a closed aquaculture space that can accommodate a sufficient amount of aquatic products. The floating box 3 of the floating system is a sealed steel structure box, which is fixedly connected to the bottom or side of the truss main body 1 by a bracket. It forms a sealed water storage chamber inside, and the volume of the water storage chamber is designed according to the overall weight and buoyancy requirements of the cage.

[0034] The drainage system includes an air compressor, a drain pipe, and a control valve. The air compressor is installed inside the equipment compartment. One end of the drain pipe connects to the water storage chamber, and the other end extends to the outside of the net cage. The control valve controls the opening and closing of the drain pipe. When it is necessary to adjust the draft of the net cage, the air compressor is started to discharge the water in the water storage chamber, causing the truss main body 1 and the net cage structure 2 to float upwards, reducing the draft. If it is necessary to increase the draft, the control valve is opened to allow water to flow into the water storage chamber by gravity. Through the regulation of the buoyancy system, the aquaculture net cage 100 can adapt to different marine climates and water level changes. For example, when there is severe weather such as typhoons at sea, the draft of the aquaculture net cage 100 is increased to submerge it, reducing the height of the aquaculture net cage 100 above the sea surface, thereby improving the aquaculture net cage 100's ability to resist typhoon attacks and ensuring the stability of the aquaculture net cage 100. After the typhoon ends, the water in the buoy 3 is discharged to submerge the aquaculture net cage 100, maintaining the truss structure 11 in a semi-submerged working state with part of it exposed above the water surface. This is to facilitate the normal work and activities of staff on the main truss 1.

[0035] Furthermore, in one embodiment, please refer to Figure 1 The pontoon 3 is located at the bottom of the working platform 12. The pontoon 3 is fixed to the crossbeam of the truss structure 11 below the working platform 12 by welding or bolting, forming an integrated structure with the working platform 12. This installation design balances the weight of the pontoon 3 with the weight of the working platform 12, preventing the overall center of gravity of the net cage from shifting, ensuring the net cage maintains a stable posture in the water, and reducing tilting caused by wind and waves. At the same time, the proximity of the pontoon 3 to the working platform 12 facilitates the inspection and maintenance of equipment such as the air compressor and control valves of the drainage system by staff, eliminating the need for prolonged underwater operations and reducing operational difficulty and safety risks. The pontoon 3's location at the bottom of the working platform 12 also prevents it from tangling with the netting 22, minimizing the impact on the aquaculture space, ensuring the free movement of aquatic products within the net cage, and improving the comfort of the aquaculture environment.

[0036] In one embodiment, please refer to Figures 1 to 4 The work platform 12 includes four, and each work platform 12 corresponds to the four corner points of a rectangle and is distributed at intervals. A connecting channel 41c is provided between adjacent work platforms 12 to connect them.

[0037] Four working platforms 12 are included, each pair spaced apart along the length of the rectangular truss main body 1, forming a rectangular distribution. This ensures that the working platforms 12 are evenly stressed on the truss structure 11, preventing any shift in the center of gravity. The distribution of the working platforms 12, corresponding to the corners of the rectangle, further enhances the structural stability of the truss main body 1. A connecting passage 41c is provided between adjacent working platforms 12. The connecting passage 41c is constructed of anti-slip steel plates and guardrails, welded and fixed to the truss structure 11, forming a ring-shaped passage around the truss main body 1. The connecting passage 41c allows the four working platforms 12 to be interconnected, enabling workers to move freely between different working platforms 12 without the need for boats. This facilitates inspection and feeding operations throughout the entire net cage area. The enclosed design of the ring-shaped passage also improves operational safety, preventing personnel from falling into the water. The distribution of the four working platforms 12 also allows for functional zoning, improving the orderliness and efficiency of aquaculture management. Specific zoning can be tailored to the actual aquaculture needs.

[0038] In one embodiment, please refer to Figure 1 and Figure 2 Each work platform 12 includes at least a first deck 1a and a second deck 1b along the height direction. The first deck 1a corresponds to the top of the truss structure 11, and the second deck 1b is located above the first deck 1a. Both the first deck 1a and the second deck 1b are provided with connecting passages 41c to connect two adjacent work platforms 12.

[0039] Each working platform 12 includes at least a first deck 1a and a second deck 1b along its height. The first deck 1a is connected to the top of the truss structure 11 by a bracket and is flush with the upper surface of the truss structure 11. It serves as the main area for daily operations, such as transporting farmed aquatic products, feeding operations, and water quality testing. The second deck 1b is supported and fixed above the first deck 1a by columns and can serve as a lookout post or equipment installation platform, facilitating observation of the overall aquaculture situation in the net cages and the surrounding aquatic environment. Both the first deck 1a and the second deck 1b are equipped with connecting passages 41c, which connect to the corresponding decks of adjacent working platforms 12, forming a two-tiered annular passage. The upper passage can be used for high-altitude inspections and equipment maintenance, while the lower passage is used for daily feeding and close observation of the growth status of aquatic products. In addition, the double-deck design also facilitates the movement of workers when the aquaculture net cage 100 is in a semi-submerged or fully submerged state. For example, when the aquaculture cage 100 is in a semi-submerged state, both the first deck 1a and the second deck 1b are above the water surface, allowing workers to move around on both decks. When severe weather necessitates submerging the aquaculture cage 100 to avoid waves, it is fully submerged, with the first deck 1a submerged and the second deck 1b above the water surface, allowing workers to move around in the compartments within the second deck 1b. The double-deck design and double-connecting passageway 41c further expand the functionality and operating space of the work platform 12, meeting the needs of different operational scenarios. Simultaneously, the upper and lower structures are independent yet interconnected, ensuring operational efficiency and improving space utilization, making it particularly suitable for the complex management needs of large-scale aquaculture cages 100.

[0040] In one embodiment, please refer to Figure 1 and Figure 3 The work platform 12 is equipped with a feed equipment compartment, and a feeding pipe extends out of the feed equipment compartment. The feeding pipe is distributed on both sides of the connecting channel 41c on the first deck 1a to feed downwards.

[0041] The working platform 12 houses a feed equipment compartment located below the first deck 1a. This compartment contains a feed mixer, an automatic feeder, and other equipment. The automatic feeder connects to an external controller via wires, enabling timed and quantitative feeding. The feeding pipes are made of food-grade PVC or stainless steel, with one end connected to the automatic feeder's outlet via a flange, and the other end extending out of the feed equipment compartment. These pipes are distributed on both sides of the connecting channel 41c on the first deck 1a. Multiple discharge holes can be installed at the bottom of the pipes, facing the aquaculture space of the net cage structure 2. When the automatic feeder is activated, feed is delivered through the feeding pipes to each discharge hole, evenly distributing it into the aquaculture space. This ensures that aquatic products in different areas of the net cage can access feed, preventing competition for food and uneven growth caused by concentrated feed. The design of the feeding pipes distributed along the connecting channel 41c allows for a wider feed coverage area. At the same time, staff can observe the feeding situation through the connecting channel 41c and adjust the feeding amount and frequency in a timely manner. The setting of the feed equipment compartment provides a protective space for the feeding equipment, preventing the equipment from being affected by wind and rain, thus improving the service life of the automatic feeding system.

[0042] In one embodiment, please refer to Figure 1 and Figure 2 Both the first deck 1a and the second deck 1b are surrounded by railings and equipped with life-saving devices.

[0043] Both decks 1a and 1b are equipped with guardrails made of welded galvanized steel pipes, effectively preventing workers from accidentally falling into the water during operations. The corners of the guardrails have rounded transitions to avoid injuries from sharp edges. Both decks 1a and 1b are equipped with lifesaving devices, including life valves, life rings, lifelines, and life jackets. The life valves and life rings are secured to the guardrails with hooks. One end of the lifeline is connected to the life ring, and the other end is fixed to a mooring post on the deck. Life jackets are stored in waterproof boxes on the deck for easy access. The guardrails provide basic safety for workers, especially in rough waters, allowing for stable standing and walking. The lifesaving devices further enhance emergency response capabilities, enabling rapid rescue in case of accidents such as falling into the water, reducing the risk of accidents and protecting the lives of workers.

[0044] In another embodiment, please refer to Figure 1 , Figure 2 , Figure 4 as well as Figure 5 The netting 22 includes a top net 221, side nets 222 and a bottom net 223. The top net 221 covers the bottom of the truss body 1, and the side nets 222 surround the outer perimeter of the aquaculture cage 100. The upper and lower ends of the side nets 222 are connected to the top net 221 and the bottom net 223 respectively. The top net 221, side nets 222 and bottom net 223 enclose the aquaculture space.

[0045] The netting 22 includes a top net 221, side nets 222, and a bottom net 223. The top net 221 is tied to the lower edge of the truss body 1 with ropes, covering the entire top of the truss body 1 to prevent birds and other predators from preying on farmed aquatic products and to prevent the aquatic products from jumping out of the net cage. The height of the side nets 222 is determined according to the depth of the aquaculture water and the growth needs of the aquatic products. They are set around the outer perimeter of the truss body 1. The upper end of the side nets 222 is connected to the bottom end of the truss body 1 by hooks or ropes, and the lower end is connected to the bottom net 223. Specifically, in this scheme, the side structure of the net cage structure 2 is formed by weaving steel wire ropes to form a basic mesh frame. The top of this frame is fixed to the truss structure 11, and the side walls are fixed to fasteners 21 spaced around the perimeter of the truss structure 11. The fasteners 21 are steel wire ropes that are thicker than the frame size. The steel wire rope frame design gives the net cage structure 2 higher strength and stability. The bottom of the frame is equipped with a cement sinker 24, which is ring-shaped according to the cross-section of the side net 222, providing the side net 222 with its own weight so that it can sink to a sufficient depth. The top of the bottom net 223 connects the side net 222 and the cement sinker 24, ensuring stable fixation on the bottom. The top net 221, side net 222, and bottom net 223 are joined together by rope stitching or hook splicing to form a completely enclosed aquaculture space. The enclosed structure can effectively prevent aquatic products from escaping and external predators from entering when the aquaculture cage 100 is submerged, while also blocking large debris from entering the cage and protecting the aquaculture environment. The combination of different types of netting 22 ensures the enclosure and safety of the aquaculture space, and allows for the selection of netting 22 with appropriate strength according to the stress requirements of each part, reducing costs while increasing the service life of the netting 22 and adapting to complex aquatic environments.

[0046] In one embodiment, please refer to Figure 1 The cage structure 2 also includes a counterweight 23, which is connected to the bottom of the bottom net 223 and pulls the bottom net 223 downward to form a cone-shaped net bag.

[0047] The net cage structure 2 also includes a counterweight 23, which is a concrete or cast iron block. The weight of the counterweight 23 is determined by the depth of the netting 22 and the intensity of the water flow, and it is connected to the bottom of the bottom netting 223 by ropes. The gravity of the counterweight 23 pulls the bottom netting 223 downwards, forming a conical net. On one hand, the downward pull of the counterweight 23 allows the netting 22 to fully stretch and extend, expanding the area of ​​the aquaculture water, thus helping to increase the scale and quantity of aquaculture. During the aquaculture process, the conical structure also facilitates the collection of fish waste at the bottom. On the other hand, the conical design allows the netting 22 to better conform to the direction of the water flow, reducing the impact of the water flow on the netting 22, and facilitating the harvesting of aquatic products in the later stages of aquaculture. During harvesting, the aquatic products will naturally gather at the bottom of the cone, eliminating the need for large-scale harvesting. The counterweight 23 ensures that the bottom netting 223 will not float upwards under the influence of the water flow, maintaining the stability of the aquaculture space and preventing the aquaculture space from shrinking due to the bottom netting 223 floating upwards, which would affect the growth of aquatic products. At the same time, the conical net structure can reduce the contact between the net 22 and the bottom silt, reduce the risk of the net 22 getting clogged, ensure the exchange of water inside and outside the net cage, and maintain the freshness of the water quality in the aquaculture area.

[0048] For further details, please refer to... Figure 1 The counterweight 23 includes multiple counterweights 23, and each counterweight 23 is spaced apart along the extension direction of the bottom net 223. Each counterweight 23 is stretched to form a cone-shaped net bag.

[0049] Multiple counterweights 23 are included, and each counterweight 23 is evenly spaced along the extension direction of the bottom net 223 to ensure that the tensile force on all parts of the bottom net 223 is uniform, avoiding damage to the bottom net 223 due to excessive local stress. Each counterweight 23 is connected to the bottom net 223 by an independent rope. The rope length is adjusted according to the design depth of the conical net bag, so that the bottom net 223 below each counterweight 23 is pulled downward to form an independent small conical net bag. Multiple small conical net bags together constitute the overall structure of the bottom net 223. The design of multiple conical net bags helps to divide the entire aquaculture water body into multiple areas, thereby catching fish waste in each area. In addition, the design of multiple counterweights 23 and multiple conical net bags can further disperse the impact force of water flow. Even if a part of the net bag is damaged, it will not affect the aquaculture function of the entire bottom net 223, improving the fault tolerance and reliability of the net cage structure 2. At the same time, multiple small cone-shaped nets can divide the aquaculture space into multiple small areas, reducing mutual interference between aquatic products. This is especially suitable for mixed farming of aquatic products at different growth stages, improving farming flexibility and yield.

[0050] In one embodiment, a power generation component 5 is provided at the top of the working platform 12, the power generation component 5 including a wind turbine and a photovoltaic power generation panel.

[0051] A power generation component 5, comprising a wind turbine and photovoltaic panels, is mounted on the top of the second deck 1b via a support frame. The support frame is higher than other facilities on the work platform 12 to ensure unobstructed views. The wind turbine can be a horizontal axis wind turbine, suitable for common wind speeds in aquaculture areas. The photovoltaic panels can be monocrystalline or polycrystalline silicon, with the installation area determined by power demand. The wind turbine and photovoltaic panels are connected to a storage battery via a controller, forming a complementary power supply system that provides power to the aquaculture cage 100's automatic feeder, air compressor, lighting equipment, and monitoring equipment. The power generation component 5 enables the aquaculture cage 100 to achieve energy self-sufficiency, eliminating reliance on an external power grid. This is particularly suitable for aquaculture in remote waters, reducing power transmission costs and line maintenance difficulties. Simultaneously, the use of clean energy reduces pollution to the aquatic environment caused by traditional oil-fired power generation, aligning with green aquaculture principles and enhancing the environmental friendliness and sustainability of the aquaculture project.

[0052] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
