Description

Technical Field

[0001] The invention relates to a deep-sea cage culture platform using a lifting capture facility, belonging to the field of aquaculture. Background Art

[0002] Traditional offshore cage aquaculture in China is currently limited by limited marine resources, water pollution, and saturated aquaculture capacity, resulting in poor sustainability and recyclability. In recent years, deep-sea aquaculture has emerged as an emerging approach to addressing the challenges facing traditional offshore aquaculture. By moving aquaculture sites farther from the coast, it can access wider marine resources, provide more suitable water quality, and alleviate the various challenges facing offshore aquaculture.

[0003] Large deep-sea floating cages are currently widely used. These cages constitute deep-sea aquaculture platforms. In the event of a strong typhoon, they can sink below the sea surface to reduce the impact of waves on the cages. They can also be moved to suitable aquaculture waters at any time according to changes in regional water quality and temperature.

[0004] For example, the previously published patent application, application number CN201711119823.6, is titled "An Automatic Lifting and Fishing Device," comprising a net cage with an opening at the top, placed in water, and a fish farming and fishing net movably disposed within the cage. The net is provided with an opening that floats on the water surface via a suspension mechanism; a lifting mechanism spaced around the inner side of the cage and used to lift the bottom of the fish farming and fishing net upward; a limiting mechanism disposed above the cage and adjacent to the lifting mechanism, used to limit the lifting height of the fish farming and fishing net; and a control box connected to the limiting mechanism and the lifting mechanism. This bellows replaces the previous manual, semi-automatic net-pulling method and is suitable for special new deep-sea aquaculture models such as aquaculture vessels.

[0005] As mentioned above, existing cage aquaculture technologies have the following problems: 1. The inner net is difficult to clean, and the cage mainly relies on rotating the cage to dry out the aquatic organisms. The overall cage structure is large, the cost is high, and the cleaning efficiency is relatively low; 2. The catching process is cumbersome, and the cage still needs to be lifted as a whole, which is inefficient; 3. When a strong typhoon hits, although the cage is completely submerged below the water surface, the fish in the upper layer of the cage are still greatly affected by the upper water flow, resulting in a high casualty rate.

[0006] In view of this, this patent application is hereby filed. Summary of the Invention

[0059] The cage aquaculture platform described in this application is capable of cultivating a variety of aquatic organisms, and can realize full-cycle aquaculture, automated sorting and catching operations from seedlings to catch in the cage components, thereby achieving a dynamic and refined intelligent all-weather aquaculture management.

[0060] Example 1, as Figures 1 to 23 As shown, a novel cage aquaculture platform 100 is placed in an open water environment for aquaculture and management. It includes an overall frame structure composed of an array of columns 102, an array of horizontal pipes 110 distributed horizontally in the upper and lower layers, and a set of horizontally arranged upper platform plates 103 connected to each other; an inner layer of tortoise shell net 104 and an outer layer of tortoise shell net 105 are arranged in the frame structure and connected vertically. That is, the inner layer of tortoise shell net 104 and the outer layer of tortoise shell net 105 are respectively surrounded by the columns 102, the horizontal pipes 110, and the upper platform plates 103 to form a number of relatively independent aquaculture chambers. Specifically,

[0061] The bottom of each group of columns 102 is fixedly connected to the seabed through the bottom plate 101 to support the above-mentioned frame structure;

[0062] An automatic or manual feeding device can be provided on the upper platform plate 103;

[0063] The mounting platform 112 is fixedly mounted on the top of the upper platform plate 103 through an array of support columns 111;

[0064] A lifting and / or suspension device such as a winch is installed on the installation platform 112. The upper platform 103 is the operating platform of the cage culture platform 100. Sufficient vertical height space is left between the installation platform 112 and the upper platform 103 for aquaculture operators to stand on the upper platform 103 to perform operations such as feeding, inspection, driving fish and controlling the catching operation.

[0065] Every four groups of columns 102 are connected to eight groups of transverse tubes 110 to form a breeding warehouse. Vertically distributed first guide rails 109 are symmetrically arranged on the inner wall of each group of columns 102. The first guide rails 109 extend continuously and are connected to the support columns 111, thereby forming a vertically long guide track connecting the upper platform plate 103 and the mounting platform 112.

[0066] An array of first fish outlets 106 below the sea level W is provided on the inner tortoise shell net 104, and an array of second fish outlets 107 below the sea level W is provided on the outer tortoise shell net 105. The first fish outlets 106 and the second fish outlets 107 are connected to connect the internal environment of the aquaculture tank with the external sea area.

[0067] The second fish outlet 107 is connected to the bottom end of the fish outlet hose 300 , and the top end of the fish outlet hose 300 is connected to the first hole 108 on the upper platform plate 103 . The fish outlet hose 300 may preferably be made of a flexible material such as rubber.

[0068] In each group of aquaculture bins formed by the inner tortoise shell net 104, the outer tortoise shell net 105, the uprights 102, the horizontal tubes 110, and the upper platform 103, a fish-driving assembly 200 is horizontally arranged. Each group of fish-driving assembly 200 is usually located vertically above the sea level W and higher than the height of the operator, so that aquaculture operations such as feeding can be carried out at this time.

[0069] The fish driving assembly 200 is composed of a fish driving frame assembly 201, an array of first winches 220, an array of second winches 230, an array of first steel cables 221, an array of second steel cables 231 and an array of roller assemblies 248;

[0071] Specifically, a brush 216 is fixedly connected to the outside of the outer frame tube 202 and the outside of the curved plate 203. The brush 216 extends continuously around the entire outside of the fish-driving frame assembly 201 and contacts the inner tortoise shell net 104. Therefore, relying on its own elasticity, the brush 216 can laterally seal the fish-driving frame assembly 201 and the inner tortoise shell net 104, preventing the cultured fish and other aquatic organisms from passing through.

[0072] On the two sets of outer frame tubes 202 arranged in parallel, a set of first bent plates 206 and a second bent plate 207 are symmetrically provided;

[0073] A group of first flat plates 208 and second flat plates 209 are symmetrically provided at the center of the cross-shaped inner frame tube 204 and at a position where the inner frame tube 204 is adjacent to the outer frame tube 202;

[0074] One end of a group of first guide pillars 210 is fixedly connected to the first curved plate 206, and the other end thereof is fixedly connected to the first flat plate 208; one end of a group of second guide pillars 260 is fixedly connected to the curved plate 203, and the other end thereof is fixedly connected to the second flat plate 209;

[0076] The two groups of first rotating shafts 212 are respectively fixedly connected to the two groups of arc-shaped plates 203 arranged on the same side, and the two groups of second rotating shafts 213 are respectively fixedly connected to the first curved plates 206 and the second curved plates 207 arranged opposite to each other. The axial center lines of each group of first rotating shafts 212 and each group of second rotating shafts 213 are parallel. A group of steel cable pulleys 214 are symmetrically arranged on the two adjacent groups of first rotating shafts 212 and second rotating shafts 213, and the steel cable pulleys 214 rotate around the connection between the first rotating shafts 212 and the second rotating shafts 213.

[0077] The first hoist 220 and the second hoist 230 are respectively fixedly installed on the installation platform 112;

[0078] The fixed ends of each set of first steel cables 221 are respectively connected to a set of arc-shaped plates 203, and the other ends thereof are wound around and connected to the output shafts of a set of first hoists 220;

[0079] Each set of second steel cables 231 is connected in a U-shaped winding shape, with its two ends respectively connected to the output shafts of two adjacent sets of second winches 230 located on the same side of the fish-driving frame assembly 201, and the two lower corners of the U-shaped second steel cables 231 are respectively mounted on the two sets of cable pulleys 214;

[0080] like Figure 17As shown, two rows of second cables 231 and second hoists 230 are arranged in a lateral direction of the fish-driving frame assembly 201, and each row is symmetrically provided with two sets of the above-mentioned structure and connection relationship. A fishing net 240 is movably arranged between the two rows of second cables 231 and second hoists 230.

[0081] like Figure 22 As shown, each roller assembly 248 is composed of a third rotating shaft 246 and a roller 247 sleeved on the third rotating shaft 246. The roller 247 can rotate around the third rotating shaft 246.

[0082] like Figure 17 and Figure 18 As shown, a plurality of roller assemblies 248 are provided on the arc-shaped plates 203 at the four end corners of the fish-driving frame assembly 201. Each group of roller assemblies 248 is integrally nested in a group of second holes 215. The rollers 247 are connected to the guide rails 109 in a vertical rolling manner, thereby realizing the vertical reciprocating lifting and lowering of the fish-driving assembly 200 as a whole.

[0083] like Figure 17 and Figure 21 As shown, the horizontal ends of the fishing net pulling plate 241 are provided with holes that are respectively sleeved on the first guide post 210 and the second guide post 260 through a clearance fit. The fishing net pulling plate 241 is provided with a plurality of third holes 242 and two groups of steel cable buckles 243 arranged symmetrically in the transverse direction. The fixed ends of the second steel cables 231 in the front and rear rows are respectively fixedly connected to the two groups of steel cable buckles 243 arranged on both sides in the transverse direction.

[0084] Parallel to the fishing net pulling plate 241, there are a plurality of fishing net rods 245. Both ends of each group of fishing net rods 245 are connected to a plurality of fishing net rings 244 respectively fitted on the first guide post 210 and the second guide post 260 through a clearance fit.

[0085] The fishing net rod 245 is arranged vertically below the fishing net 240, and the two are fixedly connected;

[0086] like Figure 17 and Figure 20 As shown, one end of the fishing net 240 is fixedly connected to the fish-driving turtle shell net 211 , and the other end thereof is fixedly connected to the third hole 242 on the fishing net pulling plate 241 .

[0087] Based on the above-mentioned structural design of the cage aquaculture platform 100, the present application proposes a novel cage aquaculture method, which sets up and manages the cage aquaculture platform 100 in an open water environment. The cage aquaculture platform 100 has a frame structure and a plurality of relatively independent aquaculture chambers composed of inner and outer double-layer tortoise shell nets, and a fish driving component 200 is set in each aquaculture chamber;

[0088] During the aquatic organism breeding and management cycle, the fish driving frame assembly 201 is driven and controlled to rise and fall vertically to complete operations such as inner net cleaning, directional driving, transfer or catching, seedling raising or returning to the field.

[0089] The cage culture method includes the following implementation stages:

[0090] Stage 1: Cage cleaning;

[0091] The two groups of second winches 230 in the front and rear rows and on the same side respectively reel in the second steel cables 231, and the two groups of second winches 230 on the other side respectively release the second steel cables 231. The two groups of second steel cables 231 in the front and rear rows simultaneously pull the fishing net pulling plate 241 from one side to the other side and move it horizontally to retract the fishing net 240 to one side, forming an opening 400 between the two adjacent groups of outer frame tubes 202 and the cross-shaped inner frame tubes 204. Figure 2 、 Figure 8 and Figure 17 As shown; when the fishing net 240 is completely folded to one side, the opening 400 is the largest;

[0092] For the convenience of the following description, the action at this time is defined as "opening the fishing net 240", and the opposite action is defined as "closing the fishing net 240";

[0093] The array of first winches 220 synchronously reel in or release the array of first steel cables 221 connected thereto, and the fish chasing frame assembly 201 is vertically lifted as a whole to drive the brush 216 to clean the inner side of the inner tortoise shell net 104;

[0094] During this stage, the cultured fish and other aquatic organisms can swim freely in the culture chamber through the opening 400. After the cleaning is completed, the fish chasing frame assembly 201 rises vertically above the sea level W, and the fishing net 240 is fully unfolded in the reverse direction to eliminate the opening 400.

[0095] Phase 2: Targeted expulsion;

[0096] The fish chasing frame assembly 201 is located vertically above the sea level W, and the fishing net 240 completely covers the opening 400;

[0097] The array of first winches 220 each synchronously releases the array of first steel cables 221 that they are driven to connect, and the fish driving frame assembly 201 as a whole descends vertically, and the cultured fish and other aquatic organisms are all driven to the bottom of the culture bin;

[0098] When the sea area where the bellows aquaculture platform is located is about to encounter severe weather conditions such as a strong typhoon, the above-mentioned operation method can be used to effectively protect aquatic organisms from being frightened or harmed;

[0099] When the bad weather ends, the array of first winches 220 respectively and synchronously reel in the array of first steel cables 221 they drive, and the fish driving frame assembly 201 as a whole rises vertically and returns to vertically above the sea level W, so that the cultured fish and other aquatic organisms can swim throughout the entire culture chamber;

[0100] Stage 3: Transfer or capture;

[0101] According to the breeding cycle and process requirements, when the farmed fish and other aquatic organisms are transferred or caught,

[0102] First, the two groups of second winches 230 in the front and rear rows on the same side respectively reel in the second steel cables 231, and the two groups of second winches 230 on the other side respectively release the second steel cables 231. The two groups of second steel cables 231 in the front and rear rows simultaneously pull the fishing net pulling plate 241 from one side to the other side, moving it horizontally to gather the fishing net 240 to one side, forming an opening 400 between the two adjacent groups of outer frame tubes 202 and the cross-shaped inner frame tubes 204, and expanding the opening 400 to its maximum.

[0103] Then, the array of first winches 220 respectively and synchronously release the array of first steel cables 221 they are connected to, and the fish driving frame assembly 201 as a whole vertically descends to the bottom of the breeding tank. At this time, all the aquatic organisms are vertically above the fish driving frame assembly 201.

[0104] Next, the fishing net 240 is retracted in the opposite direction to eliminate the opening 400, and the fish driving frame assembly 201 is vertically raised as a whole to be flush with the sea level W. During this process, the water level in the inner cabin of the fishing vessel for transfer or catching is controlled to be lower than the sea level W, and the farmed fish and other aquatic organisms are driven from the first fish outlet 106 and the second fish outlet 107 to the fishing vessel through the fish outlet hose 300.

[0105] Stage 4: Seedling cultivation or return to the field

[0106] The fish-driving frame assembly 201 is raised vertically above the sea level W, and the water level in the cabin of the fishing boat for transfer transportation or seedling placement is controlled to be higher than the sea level W. The returning fish and other aquatic organisms or seedlings enter the breeding warehouse through the fish outlet hose 300 through the first fish outlet 106 and the second fish outlet 107.
