Description

marine ranch Technical Field

[0001] This invention relates to the field of marine fisheries and aquaculture technology, and in particular to a marine ranch. Background Technology

[0002] In recent years, with the improvement of residents' living standards, the demand for aquatic products has gradually increased. In order to meet consumers' demands for the quality and quantity of aquatic products, deep-sea aquaculture has gradually become a development trend in the global fishery industry.

[0003] Among various deep-sea aquaculture methods, cage aquaculture has numerous advantages, such as rapid returns on investment, short aquaculture cycles, ease of management, and convenient harvesting, thus gaining widespread acceptance among fishermen. High-density polyethylene (HDPE) marine aquaculture cages are the most widely used, offering superior resistance to wind and waves, better flexibility, environmental friendliness, ease of recycling, and resistance to corrosion and salt, making them one of the best choices for next-generation marine aquaculture facilities.

[0004] However, HDPE net cages are flexible but lack rigidity and have poor resistance to currents, making them prone to overall deformation. In strong winds and waves, the cages sway and rock significantly, lacking stability. This is especially true in the South China Sea, where frequent typhoons and strong currents greatly impact HDPE net cage aquaculture. In coastal areas, HDPE net cages are frequently damaged and deformed by strong winds, waves, and other harsh environmental conditions, leading to fish escapes and deaths, resulting in substantial economic losses.

[0005] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0006] The main objective of this invention is to provide a marine ranch that addresses the technical problem of weak current resistance in existing marine ranch cage culture, leading to easy deformation and damage from impacts.

[0007] To achieve the above objectives, the marine ranch proposed in this invention comprises:

[0008] The fishing and livestock platform is enclosed in the shape of a hollow pasture. One end of the fishing and livestock platform is relatively fixed to the seabed, and the other end is set above the sea level.

[0009] A track, located within the hollow ranch, is connected at its outer perimeter to the aquaculture platform, dividing the hollow ranch into several aquaculture areas; and

[0010] Multiple breeding boxes, at least one of the breeding boxes being located within at least one of the breeding areas.

[0011] Optionally, the portion of the fishing and aquaculture platform submerged in the seabed is provided with multiple exchange channels for exchanging water flow.

[0012] Optionally, the exchange channel is a notch or slot, and multiple notches or slots are arranged circumferentially along the bottom of the fishing and aquaculture platform. A fixing tooth is formed between two adjacent notches or slots, and the fixing tooth is used to fix it to the seabed.

[0013] And / or, the exchange channel is a through hole, with multiple through holes extending through and spaced apart on the fishing and aquaculture platform located below sea level.

[0014] Optionally, the track has a carrying section and a positioning section, the carrying section being exposed above the sea level, the positioning section extending to the seabed, and the positioning section having a water exchange channel connecting to the exchange channel.

[0015] Optionally, the fishing and aquaculture platform and the track are integrally cast.

[0016] And / or, the fishing and aquaculture platform and the track are both made of concrete or cast with concrete and steel reinforcement.

[0017] And / or, the fishing and aquaculture platform is a hollow cylinder;

[0018] And / or, the track is configured as a cross track;

[0019] And / or, the track is provided with a slide rail, and the marine ranch also includes a crane, which is slidably connected to the slide rail.

[0020] Optionally, the distance of the enclosure above sea level at the end of the fishing and aquaculture platform is defined as H, where H ≥ 5m;

[0021] And / or, the perimeter of the fishing and aquaculture platform is defined as S, where S≥10km.

[0022] Optionally, the marine ranch also includes wind turbine units, which are mounted on the track and used to generate wind power to meet the electricity needs of the marine ranch.

[0023] Optionally, the marine ranch also includes an energy storage device, which is located on the track and electrically connected to the wind turbine. The energy storage device is used to temporarily store excess electrical energy from the wind turbine.

[0024] And / or, the marine ranch also includes a charging device, which is electrically connected to the wind turbine and is used to charge the aquaculture and ranch equipment.

[0025] Optionally, the marine ranch includes aquaculture equipment, which is electrically connected to the wind turbine. The aquaculture equipment includes at least a feeder, a fish catcher, a cleaner, and a maintenance vessel.

[0026] Optionally, the marine ranch also includes;

[0027] A monitoring station, located at one end of the track; and

[0028] A monitoring device is electrically connected to the wind turbine. The monitoring device includes a data acquisition module and a control module. The data acquisition module is distributed on the track, the wind turbine, and the aquaculture tank. The data acquisition module is signal-connected to the control module.

[0029] The marine ranch of this invention utilizes a platform—fixed at one end to the seabed and raised above sea level at the other—to combat wind and waves, thereby enhancing the overall current resistance of the marine ranch. The platform encloses a hollow ranch, within which tracks divide the ranch into several aquaculture areas. The currents within the hollow ranch enclosed by the platform are stable, making it suitable for using low-cost, flexible, and corrosion-resistant HDPE net cages as aquaculture containers, thus controlling aquaculture costs. The portion of the platform above sea level resists the impact of ocean currents, preventing the aquaculture containers from being directly impacted by wind and waves, avoiding deformation or damage. This enhances the overall wave and current resistance of the marine ranch, making it suitable for widespread use. Attached Figure Description

[0042] In recent years, with the improvement of residents' living standards, the demand for aquatic products has gradually increased. In order to meet consumers' demands for the quality and quantity of aquatic products, deep-sea aquaculture has gradually become a development trend in the global fishery industry.

[0043] Among various deep-sea aquaculture methods, cage aquaculture has numerous advantages, such as rapid returns on investment, short aquaculture cycles, ease of management, and convenient harvesting, thus gaining widespread acceptance among fishermen. High-density polyethylene (HDPE) marine aquaculture cages are the most widely used, offering superior resistance to wind and waves, better flexibility, environmental friendliness, ease of recycling, and resistance to corrosion and salt, making them one of the best choices for next-generation marine aquaculture facilities.

[0044] However, HDPE net cages are flexible but lack rigidity and have poor resistance to currents, making them prone to overall deformation. In strong winds and waves, the cages sway and rock significantly, lacking stability. This is especially true in the South China Sea, where frequent typhoons and strong currents greatly impact HDPE net cage aquaculture. In coastal areas, HDPE net cages are frequently damaged and deformed by strong winds, waves, and other harsh environmental conditions, leading to fish escapes and deaths, resulting in substantial economic losses.

[0045] This invention proposes a marine ranch 100.

[0046] Referring to Figures 1 to 3, Figure 1 is a structural schematic diagram of the marine ranch 100; Figure 2 is a partially enlarged schematic diagram of the marine ranch 100; and Figure 3 is another partially enlarged schematic diagram of the marine ranch 100.

[0047] In this embodiment of the invention, the marine ranch 100 includes a fish-farming platform 10, a track 20, and multiple aquaculture tanks 50, as shown in Figures 1 to 3. The fish-farming platform 10 forms a hollow ranch 10A, with one end of the platform fixed to the seabed and the other end extending above sea level. The track 20 is located within the hollow ranch 10A, and its outer periphery is connected to the fish-farming platform 10. The track 20 divides the hollow ranch 10A into several aquaculture areas 10B. At least one aquaculture tank 50 is located within at least one aquaculture area 10B.

[0048] The marine ranch 100 of this invention utilizes a fishing and aquaculture platform 10, with one end fixed to the seabed and the other end elevated above sea level, to resist wind and waves, thereby enhancing the overall current resistance of the marine ranch 100. The fishing and aquaculture platform 10 encloses a hollow ranch 10A, within which tracks 20 divide the hollow ranch 10A into several aquaculture areas 10B. Within the hollow ranch 10A enclosed by the fishing and aquaculture platform 10, the ocean currents are stable, making it suitable for using low-cost, flexible, and corrosion-resistant HDPE net cages as aquaculture boxes 50 for aquaculture operations, thus controlling aquaculture costs. The portion of the fishing and aquaculture platform 10 elevated above sea level resists the impact of ocean currents, preventing the aquaculture boxes 50 from being directly impacted by wind and waves, avoiding deformation or damage. This enhances the overall wave and current resistance of the marine ranch 100, making it suitable for widespread use.

[0049] It is understood that at least one breeding box 50 is located within at least one breeding area 10B, which means that each breeding area 10B is used to house the breeding box 50 for breeding operations. The multiple breeding areas 10B can be a single area for breeding or multiple areas for breeding; each breeding area 10B can house one breeding box 50 or multiple breeding boxes 50, without being limited to a single area, but preferably for sufficient breeding operations within a limited area.

[0050] It is understood that multiple breeding tanks 50 of the same or slightly different sizes can be accommodated within the same breeding area 10B. Each breeding tank 50 can house the same type of fish species. Multiple breeding tanks 50 located within the same breeding area 10B can house both the same and different types of fish species. Similarly, multiple breeding tanks 50 located in different breeding areas 10B can house both the same and different types of fish species; no single limitation is imposed here.

[0051] Optionally, the fishing and aquaculture platform 10 is a hollow cylinder.

[0052] In this embodiment, the aquaculture platform 10 is a hollow cylinder, with the hollow portion forming a hollow pasture 10A. The hollow pasture 10A encloses a portion of the sea surface as an aquaculture area. A track 20 is installed within the enclosed aquaculture area to divide the enclosed sea surface into multiple aquaculture zones 10B. Each aquaculture zone 10B is used to house aquaculture tanks 50. The track 20 allows for easy access to each aquaculture zone 10B during fisheries operations, increasing the convenience of fisheries management.

[0053] Optionally, track 20 is configured as a cross track.

[0054] In this embodiment, the track 20 is arranged in a cross shape, with its outer perimeter parallel to the sea level and connected to the inner wall of the hollow ranch 10A of the fishery and livestock platform 10. The cross shape gives the track 20 four branch tracks, one end of which is located in the center of the hollow ranch 10A and is shared by all four. The other ends of the four branch tracks are connected to the inner wall of the hollow ranch 10A, and the four connection points are evenly spaced on the circumference of the inner wall of the hollow ranch 10A, meaning the four branch tracks are arranged at 90° angles. This arrangement of the track 20 not only allows for comprehensive passage in fisheries management but also improves the connection stability between the track 20 and the fishery and livestock platform 10.

[0055] Understandably, when the aquaculture platform 10 is large enough to enclose a sufficiently large aquaculture area, a cross-shaped or multi-track system of tracks 20 can be used. The multi-track distribution of tracks 20 enhances the comprehensive coverage of aquaculture operations in the hollow ranch 10A.

[0056] Optionally, the portion of the fishing and aquaculture platform 10 submerged in the seabed is provided with multiple exchange channels 10C, which are used for exchanging water flow.

[0057] In this embodiment, the fishing and aquaculture platform 10 is a hollow cylinder with its circumference parallel to the sea level. The hollow cylindrical platform 10 includes an enclosure section 11 exposed above the sea surface and a fixed section 12 extending into the seabed along its axial direction. Multiple exchange channels 10C for exchanging water flow are located on the fixed section 12, meaning that multiple exchange channels 10C are distributed on the fishing and aquaculture platform 10 below the sea level. The multiple exchange channels 10C are respectively opened through the wall thickness of the fishing and aquaculture platform 10, so that water flow inside and outside the enclosed hollow pasture 10A can be exchanged through the exchange channels 10C, reducing the direct impact of seabed water flow on the fishing and aquaculture platform 10.

[0058] Optionally, the exchange channel 10C is a notch, and multiple notches are arranged circumferentially along the bottom of the fishing platform 10. A fixing tooth 15 is formed between two adjacent notches, and the fixing tooth 15 is used to fix it to the seabed.

[0059] In this embodiment, multiple exchange channels 10C are distributed on the fixed section 12 of the aquaculture platform 10 below the sea level. Each exchange channel 10C is a notch or slot. Multiple notches and slots are arranged at intervals along the circumference of the fixed section 12, so that a fixing tooth 15 is formed between two adjacent notches and slots. The fixing tooth 15 is used to fix the fixed section 12 to the seabed. The circumferential arrangement of the fixing tooth 15 and the notch and slot can not only meet the water flow exchange inside and outside the hollow ranch 10A, but also stably fix the aquaculture platform 10 to the seabed, providing stable platform support stability.

[0060] Optionally, the exchange channel 10C is a through hole, with multiple through holes running through and spaced apart on the fishing and aquaculture platform 10 located below sea level.

[0061] In another embodiment, the multiple exchange channels 10C are configured as multiple through holes, that is, multiple through holes are provided on the fixed section 12 of the fishing and aquaculture platform 10 located below the sea level. The multiple through holes are opened through the wall thickness of the fishing and aquaculture platform 10, which can satisfy the water flow exchange inside and outside the hollow ranch 10A as much as possible, reduce the direct impact of the seabed water flow on the fixed section 12 of the fishing and aquaculture platform 10, and improve the stability of the fixed section 12 located in the seabed.

[0062] Optionally, the distance between the end of the fishing and aquaculture platform 10 and the sea level is defined as H, where H ≥ 5m; and / or, the perimeter of the fishing and aquaculture platform 10 is defined as S, where S ≥ 10km.

[0063] In this embodiment, the part of the aquaculture platform 10 that is above sea level is the enclosure section 11. The enclosure section 11 is more than 5m high. In actual use, it is set at a height of about 10m, which can block most of the impact of sea waves, create a stable aquaculture environment for the multiple aquaculture tanks 50 located in the aquaculture area 10B, improve the aquaculture effect, and enhance the overall resistance of the marine ranch 100 to currents.

[0064] In another embodiment, the enclosure section 11 of the aquaculture platform 10 is more than 5 meters high, and the inner wall circumference of the enclosure section 11 can be as long as 10 km or more, which can provide a sufficiently large enclosed area of ​​the aquaculture platform 10, provide a sufficiently large hollow pasture 10A, improve breeding capacity, and increase production.

[0065] In one specific embodiment, the concrete aquaculture platform 10 is divided into four aquaculture areas 10B by a cross-shaped track structure 20. These four aquaculture areas 10B can raise different or the same fish species according to actual needs. Each aquaculture area 10B has an area of ​​approximately 2 km². Based on a perimeter of 100m for each HDPE net cage and a minimum interval of 30m between adjacent HDPE aquaculture cages 50, approximately 500 HDPE net cages can be arranged in each aquaculture area 10B, thus increasing aquaculture capacity.

[0066] Optionally, the fishing and livestock platform 10 and the track 20 are integrally cast; and / or, the fishing and livestock platform 10 and the track 20 are both made of concrete or concrete and steel reinforcement are cast together.

[0067] In this embodiment, the fishing and livestock platform 10 is formed by concrete pouring, or by pouring concrete and reinforcing steel simultaneously. The reinforcing steel is used to enhance the stress and shear force of the finished product after concrete pouring, providing a structurally stable and corrosion-resistant fishing and livestock platform 10. The structure of the track 20 is the same as that of the fishing and livestock platform 10.

[0068] In one embodiment, the track 20 and the aquaculture platform 10 are cast separately and then assembled together, or they are cast as a whole at the beginning of the installation, so that the two structures are firmly connected and the overall structural stability of the marine ranch 100 is improved.

[0069] Optionally, the track 20 has a carrying section 21 and a positioning section 22, the carrying section 21 being exposed above the sea level and the positioning section 22 extending to the seabed, the positioning section 22 being provided with a water exchange channel 20A connecting the exchange channel 10C.

[0070] In this embodiment, the track 20 has a support section 21 and a positioning section 22 in a direction perpendicular to the sea level. That is, the track 20 includes a support section 21 and a positioning section 22 in a direction parallel to the axial direction of the aquaculture platform 10. The positioning section 22 extends into the seabed for fixation within the seabed. The track 20 is entirely located within the space of the hollow ranch 10A. The positioning section 22 located within the seabed is equipped with multiple water exchange channels 20A to facilitate water exchange between the corresponding seabed areas below the multiple aquaculture areas 10B. This enables water exchange between the inside and outside of the entire marine ranch 100 on the seabed, reduces the impact of ocean currents, and improves the stability of the marine ranch 100.

[0071] Furthermore, the bearing section 21 is used to provide a road for vehicles or people to pass through, while also improving the structural support stability of the fishing and aquaculture platform 10.

[0072] Optionally, the track 20 is provided with a slide rail, and the marine ranch 100 also includes a crane 60, which is slidably connected to the slide rail.

[0073] In this embodiment, the bearing section 21 of the track 20 is provided with a passage, which allows people and vehicles to pass through separately or simultaneously. On the surface of the bearing section 21, a single row or double row of slide rails are also provided. The marine ranch 100 also includes a crane 60, which is slidably connected to the slide rails for operations such as fishing, transfer and hoisting.

[0074] Understandably, track 20 includes multiple sub-tracks, and the slide rails of these multiple sub-tracks are interconnected, which improves the smoothness of the crane 60's movement and the ease of its relocation.

[0075] Optionally, the marine ranch 100 also includes a wind turbine 30, which is mounted on the track 20. The wind turbine 30 uses wind power to generate electricity, which is used to meet the electricity demand of the marine ranch 100, thus saving energy and protecting the environment.

[0076] In this embodiment, the wind turbine 30 includes a tower fixed on the track 20, rotating blades, a nacelle, and a busbar structure for power transmission that is not located inside the tower. Using wind power generation can effectively utilize offshore wind resources and save on the layout of power supply equipment and submarine cables that need to be drawn from the land to the sea. This allows the marine ranch 100 of the present invention to be built both near the sea and in the open sea.

[0077] Optionally, the marine ranch 100 also includes an energy storage device (not shown), which is located on the track 20 and electrically connected to the wind turbine 30. The energy storage device is used to temporarily store excess electrical energy from the wind turbine 30.

[0078] In this embodiment, the energy storage device can store the electrical energy converted from wind power by the wind turbine 30. This means that excess electrical energy generated after the wind turbine 30 meets daily electricity needs can be temporarily stored. The stored energy can then be used to compensate for power supply when wind speeds are low or the power generation is insufficient to meet current demand. This combination of wind turbine 30 and energy storage eliminates the need for submarine cables to draw power from or transmit it to the land, thus saving on cable requirements, construction costs, and the reliability of the self-sufficient closed-loop system. This makes the marine ranch 100 more suitable for offshore aquaculture.

[0079] Specifically, a wind turbine 30, exemplarily a 5MW wind turbine, is arranged in the center of the constructed concrete aquaculture platform 10. This can meet the electricity needs of the marine ranch 100. Simultaneously, the power generated by the wind turbine 30 is utilized by the marine ranch 100 and energy storage equipment, eliminating the need for additional submarine cables to transmit excess power back to shore, thus saving on cable costs. Furthermore, this arrangement effectively utilizes the abundant offshore wind resources and allows the wind turbine 30 to be housed within the enclosure section 11 of the aquaculture platform 10, avoiding the scouring problems associated with traditional offshore wind turbine foundations.

[0080] Optionally, the marine ranch 100 includes aquaculture equipment, which is electrically connected to the wind turbine 30. The aquaculture equipment includes at least a feeder, a fish catcher, a cleaner, and a maintenance vessel.

[0081] In this embodiment, the marine ranch 100 includes complete aquaculture and ranching equipment to support fully automated operations such as feeding, fish harvesting, monitoring, cleaning dead fish, and cleaning fishing nets. The power supply for the aquaculture and ranching equipment, including the feeder, fish harvester, cleaning machine, and maintenance vessel, can be provided by the wind turbine 30 or energy storage equipment.

[0082] Optionally, the marine ranch 100 also includes a charging device electrically connected to the wind turbine 30 for charging the aquaculture and ranching equipment.

[0083] In this embodiment, the marine ranch 100 also includes an independently installed charging device. This charging device and the energy storage device can be installed independently or integrated. Both the charging device and the energy storage device are connected to the wind turbine 30 to obtain power. For safety reasons, the charging device transforms the high-voltage electricity generated by the wind turbine 30 before transmitting it to charge the aquaculture and ranch equipment, thereby improving power safety.

[0084] Optionally, the marine ranch 100 also includes a monitoring station 70 and a monitoring device, with the monitoring station 70 located at one end of the track 20. The monitoring device is electrically connected to the wind turbine 30 and includes a data acquisition module and a control module. The data acquisition module is distributed across the track 20, the wind turbine 30, and the aquaculture tank 50, and the data acquisition module is signal-connected to the control module.

[0085] In this embodiment, the monitoring station 70 takes pictures on the track 20, and the acquisition modules of the monitoring device are distributed on the track 20, the breeding area 10B, the wind turbine 30 and the breeding box 50 to synchronously monitor the operation of the track 20, the wind turbine 30 and the breeding box 50.

[0086] The marine ranch 100 is equipped with a fisheries monitoring center and a wind power control center to monitor fish farming and wind power operation, corresponding to the aquaculture equipment and wind turbine units 30. For example, the fisheries monitoring center needs to monitor parameters such as seawater temperature, pressure, and dissolved oxygen at the bottom of the aquaculture tanks 50, while the wind power control center needs to monitor parameters such as air temperature and humidity, wind speed and direction, and the amount and surplus of electrical energy reserves for comprehensive management. The fisheries monitoring center and the wind power control center are integrated into one system, sharing a single monitoring system to monitor both fish farming and wind power operation.

[0087] The above description is merely a preferred 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's specification and drawings under the inventive 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.
