Description

Technical Field

[0001] The present invention relates to the technical field of marine aquaculture equipment, and particularly relates to a combined deep - sea and far - sea aquaculture cage. Background Art

[0002] In deep - water sea areas, the wind and waves are generally large, and the influence of wind and waves on cage aquaculture equipment is particularly obvious. Most of the existing cages are HDPE (high - density polyethylene) circular or square cages. The application document with the patent number 2016207973571 discloses an oval cage, which is composed of an oval frame, a bottom net, side - wall nets, and a floating frame. This cage is easy to manufacture and has good use effects. The application document with the patent number 2014202577606 discloses a floating circular cage for yellow croaker breeding, including a circular frame, circular side net sheets, and a circular bottom net sheet.

[0003] The overall structure of the existing cages has weak anti - wind - and - wave ability. Moreover, the cages are in an independent layout structure, and the cages cannot support each other, resulting in poor anti - wind - and - wave ability and short service life. In addition, each cage uses a simple mooring system. When the number of cages arranged is large, it occupies a large sea area and requires a large number of mooring systems. Furthermore, most of the existing cages do not introduce information equipment, and the monitoring of the aquaculture process and the collection and collation of aquaculture data are very weak, and cannot provide data and technical support for the later aquaculture technology and aquaculture efficiency of aquaculture companies. Summary of the Invention

[0004] In order to solve the problems existing in the above - mentioned background art, the present invention provides a combined deep - sea and far - sea aquaculture cage, which arranges aquaculture cage units in combination, adopts a specific mooring system and an interception net system, has strong anti - wind - and - wave ability, improves the stability of the aquaculture environment of the internal cages, designs the structure of the aquaculture cage units, can make full use of the target sea area, reduce the operation cost of the fishing ground, increase the unit - yield area, has good economy, and also realizes the monitoring and information recording of the aquaculture process in the aquaculture area of the sea area.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The present invention provides a combined deep - sea and far - sea aquaculture cage, including a plurality of aquaculture cage units, a mooring system, and an interception net system. The plurality of aquaculture cage units are combined to form an aquaculture array. The aquaculture cage units are fixed by the mooring system. A passage for ships to pass through is reserved between two adjacent aquaculture cage units. The interception net system is arranged on the periphery of the aquaculture array. Specifically, 1000 sets of aquaculture cage units are combined in a 40 * 25 arrangement to form a rectangular aquaculture array, and a passage with a 10 - meter distance is left both horizontally and vertically between the aquaculture cage units as a shipping lane for ships to pass through.

[0007] The aquaculture cage unit includes a plurality of cages, towing ropes, a positioning grid, and surface floats. The surface floats are located on the sea surface. The positioning grid is located directly below the surface floats. Both the surface floats and the positioning grid are fixed by the mooring system. There is a certain height difference between the positioning grid and the seabed. A plurality of positioning spaces for limiting and fixing the cages are formed inside the positioning grid. The bottom end of the cage is in contact with and fixed to the seabed. A plurality of towing ropes are connected to the outside of the cage, and the ends of the towing ropes are connected to the surface floats. The overall dimensions of the surface floats and the positioning grid are determined by the number and size of the cages to be positioned in each aquaculture cage unit. The size of the positioning spaces formed inside the positioning grid is adapted to the size of the cages, and the shape of the surface floats matches the shape of the positioning grid. Specifically, the surface floats are of a frame structure, which is convenient for the connection of the ends of the towing ropes to the surface floats, making the towing ropes vertical and not interfering with each other. When harvesting sea cucumbers, the towing ropes connected to the surface floats are pulled up, that is, the cages are lifted upward as a whole, which greatly saves time and labor costs and improves the sea cucumber harvesting efficiency.

[0008] Further improvement lies in that the positioning grid is formed by horizontally and vertically interweaving ropes. The ropes are ultra-high molecular weight polyethylene braided ropes or steel wires. A wear-resistant coating and an anti-biofouling coating are sequentially provided on the outer side of the ropes, which improves the wear resistance of the positioning grid, prevents marine organisms from attaching and growing on the ropes, and increases the underwater service life of the positioning grid.

[0009] Further improvement lies in that connectors are provided on the towing ropes outside the cages, and the ends of the connectors form an openable and closable connection with the ropes at the positioning spaces in the positioning grid.

[0010] In actual application, the connectors on the towing ropes are connected to the corresponding ropes in the grid. At this time, the cages are limited to the lower part of the corresponding positioning spaces in the grid, and it is not easy to get entangled with adjacent cages and will not be carried away by the wave current. When the tide ebbs, the towing ropes will slacken. At this time, under the action of the towing ropes, connectors, and ropes in the grid, the top of the cages will not sink, ensuring that the internal space of the cages is not compressed, thus overcoming the influence of the tidal difference on the internal aquaculture space of the cages. When the cages are being installed underwater, to ensure that multiple cages are orderly lowered to the designated positions on the seabed, the cages can be first fixed in the positioning grid on the water surface, and then multiple cages and the positioning grid are allowed to sink to the bottom together. This can greatly reduce the workload of divers on the seabed and make the construction and installation more convenient and efficient.

[0011] The connecting piece can be a mechanically opened and closed structure, such as a hook, which has a relatively low cost. The connecting end of the hook is fixed to the towing rope by tying with a rope, and the opening and closing end of the hook is connected to the rope at the positioning space in the positioning grid. However, when collecting data, the diver needs to operate to separate the hook from the rope in the positioning grid. In specific applications, in order to avoid manual intervention during data collection, the connecting piece can also be an automatically controlled opened and closed structure. During data collection, the connecting piece is directly and automatically controlled to separate from the rope in the positioning grid without the need for diver operation.

[0012] Further improvement lies in that the interception net system includes a buoyancy component, a plurality of interception net bodies, and a first anchoring component. The plurality of interception net bodies are distributed around the aquaculture array, and a ship passage is formed between the interception net bodies for ships to enter the aquaculture area. The top end of the interception net body is connected to the buoyancy component located on the sea surface, and the bottom end of the interception net body is connected to the first anchoring component located on the seabed. The interception net body is woven from intelligent ropes capable of transmitting optical signals or electrical signals. The intelligent ropes in the interception net body are electrically connected to an underwater signal processing cabin through cables. The underwater signal processing cabin is electrically connected to a water surface controller located on the buoyancy component, and the water surface controller is signal-connected to a display located on the shore.

[0013] During actual application, the top end of the interception net body is connected to the buoyancy component, and the bottom end of the interception net body is connected to the first anchoring component, which is convenient for construction. It can effectively intercept large floating garbage at sea, unfriendly marine organisms such as sharks outside the aquaculture area, ensure that the internal aquaculture area is not disturbed, and at the same time has the function of reducing flow and protecting. In addition, the interception net body also has an alarm function when the net body is attacked or damaged. When the interception net body is attacked and damaged, by tracking the optical signal or electrical signal of the intelligent rope, the broken or damaged position can be accurately displayed and found, and it can be repaired in time to reduce the loss of deep-sea aquaculture.

[0014] Reinforcing ribs are arranged horizontally and vertically on the side of the interception net body. An upper net steel is arranged at the top end of the interception net body, and a lower net steel is arranged at the bottom end of the interception net body. The reinforcing ribs are woven from high-strength fibers. By setting the reinforcing ribs, the strength of the interception net body is increased. During actual production, the net body is woven on both sides of the upper net cable and the lower net cable and connected into an interception net body.

[0015] The buoyancy component is a floating drum, and the material of the floating drum is high-density polyethylene. A through hole for the upper cable to pass through is opened on the floating drum, and the upper cable is tied and connected to the upper net steel.

[0016] The first anchoring component is a pile anchor or an anchor block. In this embodiment, the anchoring component is a pile anchor. The lower cable is tied and connected to the lower net steel, and then the lower cable is tied and connected to the pile anchor. The lower cable is a steel wire cable, thereby achieving the purpose of opening the interception net body and fixing the position of the interception net body.

[0017] A further improvement lies in that the combined deep - sea and far - sea aquaculture cage further includes an underwater monitoring system, which includes an underwater detection device and a processor. The underwater detection device is installed on the cage and the interception net body, the underwater detection device is connected to the processor, and the processor is connected to the water - surface controller. Through the underwater monitoring system, the monitoring and information recording of the aquaculture process are realized.

[0018] A further improvement lies in that the underwater detection device is one or a combination of a temperature sensor, a salinity sensor, a pH value sensor, a dissolved oxygen sensor, and a camera.

[0019] A further improvement lies in that the cage includes a net body, an upper net cover, a sea cucumber attachment base, a counterweight assembly, and a support pipe; the upper net cover is provided at the top opening of the net body, the support pipe is provided at the top edge of the net body, the sea cucumber attachment base is provided at the inner bottom of the net body, the counterweight assembly is provided at the bottom end of the net body, the counterweight assembly is fixed to the seabed, and a plurality of towing ropes are symmetrically connected to the outside of the net body. The ends of the towing ropes are sewn on the side of the net body. Specifically, the ends of the towing ropes are sewn from the bottom end to the top end of the side of the net body, ensuring the balanced distribution of the traction force of the towing ropes on the cage.

[0020] Through the counterweight assembly at the bottom of the net body, the bottom of the cage is propped open and firmly "locked" to the seabed, solving the problem that sea cucumbers cannot survive in high temperatures in summer. Moreover, the seabed is rich in sea mud and algal microorganisms, providing a rich variety of foods for sea cucumbers, restoring the living environment of wild sea cucumbers, and enabling the cultivation of healthier and more nutritious sea cucumbers. In addition, the flow at the seabed is slower and gentler than the waves on the sea surface. The cage is located at the seabed, providing a more comfortable, stable, and safe living space for sea cucumbers; the sea cucumber attachment base is provided at the inner bottom of the net body. When in use, the sea cucumber attachment base is laid flat on the seabed for sea cucumbers to attach and grow. At the same time, the sea cucumber attachment base can also be used as a carrier of nutrients, and its interior can be filled with nutrients required for the growth of sea cucumbers. These nutrients are slowly released during the growth process of sea cucumbers and are absorbed by the sea cucumbers; by setting an upper net cover and a support pipe at the top of the net body, the two cooperate to float upward, propping open the upper part of the cage, and by setting towing ropes on the outside of the net body, the ends of the towing ropes are connected to the water - surface floating body, and the towing ropes lift and prop open the side of the cage, which can maintain the shape of the cage and ensure that the internal aquaculture space of the cage does not deform. When harvesting sea cucumbers, the whole cage can be lifted by the towing ropes connected to the water - surface floating body, and then the operation of harvesting sea cucumbers can be carried out.

[0021] A further improvement lies in that the net body is made of high - strength polyester material, which is firm and durable. Ultra - high - molecular - weight polyethylene material can also be selected. The upper net cover is made of ultra - high - molecular - weight polyethylene material. The mesh size of the net body and the upper net cover is smaller than the volume of sea cucumbers, ensuring that sea cucumbers will not be washed outside the cage. The upper net cover is made of ultra - high - molecular - weight polyethylene net with a density lower than that of water, which can ensure that the upper net cover floats and does not drag on the bottom, forming a certain aquaculture space inside the cage.

[0022] A further improvement lies in that the sea cucumber attachment base is a three-dimensional spacer fabric, and the sea cucumber attachment base is sewn to the inner bottom and side surfaces of the net body by sewing threads. The structure of the three-dimensional spacer fabric is similar to that of a sandwich. A three-dimensional woven fabric is formed by connecting a group of vertical yarns between two parallel fabric plane structures. Specifically, one side of the surface of the three-dimensional knitted spacer fabric is sparse and the other side is dense, and the thickness is about 3-6 mm. The three-dimensional spacer fabric is located at the inner bottom of the net cage, providing a soft and comfortable bedding for the sea cucumbers. In actual application, the three-dimensional spacer fabric located at the inner bottom of the net cage is laid flat on the seabed, and the sea cucumbers attach to the three-dimensional spacer fabric and grow. Nutrients required for the growth of sea cucumbers can be filled inside the three-dimensional spacer fabric, and these nutrients are slowly released during the growth process of the sea cucumbers and absorbed by the sea cucumbers. Therefore, the three-dimensional spacer fabric is both a growth base fabric for sea cucumbers and a carrier for nutrients.

[0023] In actual application, a collection opening for collecting sea cucumbers is reserved between the upper net cover and the top of the net body. The collection opening is usually set at the four corners for easy opening. The specific setting position can also be adjusted according to actual needs. The collection opening can be closed by tying with a connecting rope, which has a relatively low overall cost. Other openable methods in the prior art can also be used.

[0024] The counterweight assembly is a counterweight anchor chain or a counterweight block. In this embodiment, the counterweight assembly is a counterweight anchor chain, and the counterweight anchor chain is tied to the four bottom edges of the net body bottom.

[0025] A further improvement lies in that the mooring system includes a first connecting rope, a second connecting rope and a second anchoring assembly. The first connecting rope is obliquely pulled outside the surface floating body, and the end of the first connecting rope is connected to the second anchoring assembly located on the seabed. The second connecting rope is connected to the outside of the positioning grid, and the second connecting rope is connected to the second anchoring assembly.

[0026] In this embodiment, the second anchoring assembly is an anchor block. A vertical column is pre-embedded in the anchor block during pouring. A vertical column is formed at the top of the anchor block. One end of the first connecting rope is fixedly connected to the anchor block to limit the floating surface floating body within a certain range of activities. One end of the second connecting rope is connected to the vertical column, and the positioning grid can be tensioned and lifted to a certain height above the seabed.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] In the present invention, multiple aquaculture cage units are combined to form an aquaculture array, and channels are reserved between the aquaculture cage units for ships to pass through. An interception net system is arranged on the periphery of the aquaculture array, which can effectively intercept large floating garbage in the sea, unfriendly marine organisms such as sharks outside the aquaculture area, ensure that the internal aquaculture area is not disturbed, and at the same time has the function of filtering waves and reducing flow, improving the stability of the aquaculture environment of the internal cages. This interception net system also has an alarm function when the net body is attacked or damaged, which can quickly and accurately locate the damaged position of the net body, facilitate the rapid repair of the net body, reduce the losses of deep-sea aquaculture, and a ship passage is reserved in the interception net system for ships to enter the aquaculture area, improving the integration and modernization of deep-sea aquaculture cages;

[0029] By adopting an anchoring system to fix each aquaculture cage unit, compared with the existing underwater installation and fixing method of cages, the anchoring and fixing strength of the aquaculture cage units is increased, the anti-wave and anti-wind ability of the aquaculture cage combination is enhanced, and at the same time, the cost of anchoring and fixing is controlled;

[0030] Through the design of the structure of the aquaculture cage unit, the aquaculture cage unit is divided into three layers: upper, middle and lower. The upper layer is a water surface floating body, which provides buoyancy for the whole unit. At the same time, the upper layer can also be used for cage culture of algae and scallops. The debris of the upper layer algae provides food for fish and sea cucumbers in the middle and lower layers, and the oxygen produced by its photosynthesis is also utilized. The middle layer is composed of anchor ropes and towing ropes, so the space is relatively large. This space can be used to culture fish. The fish breathe to produce carbon dioxide, and the feces decomposition produces nitrogen and phosphorus nutrients, which can be provided for algae to carry out photosynthesis. The lower layer is a cage structure and a positioning grid structure. The positioning grid structure can orderly arrange and limit the cages to specific positions on the seabed, solve the problem of entanglement and knotting between multiple side-by-side cages, and will not be swept away by wave currents, saving aquaculture space. The inside of the cage is used to culture sea cucumbers, providing a more stable and better living environment for sea cucumber culture. The sea cucumbers in the lower layer feed on the debris of seaweed and the feces that have not been decomposed by fish. At the same time, the feces of sea cucumbers will also decompose into nutrients such as nitrogen and phosphorus, which are absorbed and utilized by seaweed. The algae, fish and sea cucumbers in these three layers form a food chain, mutually beneficial, which is not only beneficial to their respective growth and development, but also reduces seawater pollution, and at the same time greatly improves the aquaculture utilization rate of the sea area and increases aquaculture income.

[0031] This combined deep-sea aquaculture cage has strong anti-wave and anti-wind ability, improves the stability of the aquaculture environment of the internal cages, can make full use of the target sea area, reduces the operation cost of the fishing ground, increases the yield per unit area, has good economy, and also realizes the monitoring and information recording of the aquaculture process in the sea area aquaculture area.

Specific Embodiments

[0041] The embodiments of the present invention disclose a modular deep - sea and far - sea aquaculture cage, as shown in Figure 1 and Figure 2As shown in the figure, it includes multiple aquaculture cage units 1, an anchoring system 24, and an interception net system 16. The multiple aquaculture cage units 1 are combined to form an aquaculture array. The aquaculture cage units 1 are fixed by the anchoring system 24. A passage 2 for ships to pass through is reserved between two adjacent aquaculture cage units 1. The interception net system 16 is arranged on the periphery of the aquaculture array. In this embodiment, 1000 sets of aquaculture cage units 1 are combined to form a rectangular aquaculture array in a 40*25 arrangement. A passage 2 with a distance of 10 meters is left both horizontally and vertically between the aquaculture cage units 1 as a shipping lane for ships to pass through. The interception net system 16 can effectively intercept large floating garbage at sea and unfriendly marine organisms such as sharks outside the aquaculture area, ensuring that the internal aquaculture area is not disturbed. At the same time, it also has the function of filtering waves and reducing the flow rate, improving the stability of the aquaculture environment of the internal cages 3. This interception net system 16 also has an alarm function when the net body is attacked or damaged, and can quickly and accurately locate the damaged position of the net body 4, which is conducive to the rapid repair of the net body, reducing the losses of deep-sea aquaculture. An access opening 17 for ships is reserved in the interception net system 16 to allow ships to enter the aquaculture area, improving the integration and modernization of deep-sea aquaculture cages; by using the anchoring system 24 to fix each aquaculture cage unit 1, compared with the existing underwater installation and fixing method of cages, the anchoring and fixing strength of the aquaculture cage units 1 is increased, the anti-wave and anti-wind ability of the aquaculture cage combination is enhanced, and at the same time, the cost of anchoring and fixing is controlled.

[0042] As Figure 3 and Figure 4 shown, the aquaculture cage unit 1 includes multiple cages 3, towing ropes 10, positioning grids 12, and surface floats 15. The surface floats 15 are located on the sea surface, and the positioning grids 12 are located directly below the surface floats 15. Both the surface floats 15 and the positioning grids 12 are fixed by the anchoring system 24, and there is a certain height difference between the positioning grids 12 and the seabed. Multiple positioning spaces 14 for limiting and fixing the cages 3 are formed inside the positioning grids 12. The bottom ends of the cages 3 are in contact with and fixed to the seabed. A plurality of towing ropes 10 are connected to the outside of the cages 3, and the ends of the towing ropes 10 are connected to the surface floats 15. The overall dimensions of the surface floats 15 and the positioning grids 12 are determined by the number and size of the cages 3 to be positioned in each aquaculture cage unit 1. The size of the positioning spaces 14 formed inside the positioning grids 12 is adapted to the size of the cages 3, and the shape of the surface floats 15 matches the shape of the positioning grids 12. Specifically, the surface floats 15 are of a frame structure, which is convenient for connecting the ends of the towing ropes 10 to the surface floats 15, so that the towing ropes 10 are vertically arranged and do not interfere with each other. When harvesting sea cucumbers, the towing ropes 10 connected to the surface floats 15 are pulled up, that is, the cages 3 are lifted upward as a whole, greatly saving time and labor costs and improving the sea cucumber harvesting efficiency.

[0043] By designing the structure of the aquaculture cage unit 1, the aquaculture cage unit 1 is divided into three layers: upper, middle and lower. The upper layer is the water surface floating body 15, which provides buoyancy for the whole unit. At the same time, the upper layer can also be used for cage culture of algae and scallops. The debris of the upper layer algae provides food for the fish and sea cucumbers in the middle and lower layers, and the oxygen produced by its photosynthesis is also utilized; The middle layer is composed of the anchor rope and the towing rope 10, so the space is relatively large. This space can be used to culture fish. The fish breathe to produce carbon dioxide, and the feces decompose to produce nitrogen and phosphorus nutrients, which can be provided for the algae to carry out photosynthesis; The lower layer is the structure of the cage 3 and the positioning grid 12. The positioning grid 12 can orderly arrange and limit the cages 3 to specific positions on the seabed, solve the problem of entanglement and knotting between multiple side-by-side cages 3, and will not be carried away by the wave current, saving the aquaculture space. The inside of the cage 3 is used to culture sea cucumbers, providing a more stable and better living environment for sea cucumber culture. The sea cucumbers in the lower layer feed on the debris of seaweed and the feces not decomposed by fish. At the same time, the feces of sea cucumbers will also decompose into nutrients such as nitrogen and phosphorus, which are absorbed and utilized by seaweed; The algae, fish and sea cucumbers in these three layers form a food chain, mutually beneficial, which is not only beneficial to their respective growth and development, but also reduces seawater pollution, and at the same time greatly improves the aquaculture utilization rate of the sea area and increases the aquaculture income.

[0044] The positioning grid 12 is formed by the horizontal and vertical interweaving of the ropes 13. The ropes 13 are ultra-high molecular weight polyethylene braided ropes or steel wires. An abrasion-resistant coating and an anti-biofouling coating are sequentially arranged on the outer side of the ropes 13, which improves the abrasion resistance of the positioning grid 12 and prevents marine organisms from growing on the ropes 13, increasing the underwater service life of the positioning grid 12.

[0045] Such as Figure 5As shown in the figure, a connecting piece 11 is provided on the towing rope 10 outside the cage 3. The end of the connecting piece 11 and the rope 13 at the positioning space 14 in the positioning grid 12 form an opening and closing connection. In actual application, the connecting piece 11 on the towing rope 10 is connected to the rope 13 at the corresponding position in the grid. At this time, the cage 3 is limited below the corresponding positioning space 14 in the grid, and it is not easy to be entangled with adjacent cages 3, nor will it be carried away by the wave current; during the ebb tide, the towing rope 10 will be slack. At this time, under the action of the towing rope 10, the connecting piece 11 and the rope 13 in the grid, the top of the cage 3 will not sink, ensuring that the internal space of the cage 3 is not compressed, thus overcoming the influence of the tidal difference on the internal aquaculture space of the cage 3. When the cage 3 is under water construction, to ensure that multiple cages 3 fall into the designated positions on the seabed in an orderly manner, the cage 3 can be fixed in the positioning grid 12 on the water surface first, and then multiple cages 3 and the positioning grid 12 are allowed to sink to the bottom together. This can greatly reduce the workload of divers on the seabed and make the construction and installation more convenient and efficient. The connecting piece 11 can be selected as a mechanical opening and closing structure, such as a hook, which has a low cost. The connecting end of the hook is fixed to the towing rope 10 by rope binding, and the opening and closing end of the hook is connected to the rope 13 at the positioning space 14 in the positioning grid 12. However, during the collection of the cage, divers need to operate to separate the hook from the rope 13 in the positioning grid 12. In specific applications, in order to avoid manual intervention during the collection of the cage, the connecting piece 11 can also be selected as an automatically controlled opening and closing structure. During the collection of the cage, the connecting piece 11 is directly and automatically controlled to separate from the rope 13 in the positioning grid 12, without the need for divers to operate.

[0046] As Figure 6 As shown in the figure, the interception net system 16 includes a buoyancy component 18, a plurality of interception net bodies 20 and a first anchoring component 19. The plurality of interception net bodies 20 are distributed on the periphery of the aquaculture array, and a ship passage 17 for ships to pass through is formed between the interception net bodies 20 to allow ships to enter the aquaculture area. The top of the interception net body 20 is connected to the buoyancy component 18 located on the sea surface, the bottom of the interception net body 20 is connected to the first anchoring component 19 located on the seabed, and the interception net body 20 is woven by intelligent ropes that can transmit optical signals or electrical signals. The intelligent ropes in the interception net body 20 are electrically connected to an underwater signal processing cabin through cables, the underwater signal processing cabin is electrically connected to a water surface controller located on the buoyancy component 18, and the water surface controller is signal-connected to a display located on the shore. In actual application, the top of the interception net body 20 is connected to the buoyancy component 18, and the bottom of the interception net body 20 is connected to the first anchoring component 19. The construction is convenient, and it can effectively intercept large floating garbage at sea, unfriendly marine organisms such as sharks outside the aquaculture area, ensure that the internal aquaculture area is not disturbed, and at the same time has the function of reducing the flow and protecting. In addition, the interception net body 20 also has an alarm function for the attack or damage of the net body 4. When the interception net body 20 is attacked and damaged, by tracking the optical signal or electrical signal of the intelligent rope, the fracture or damaged position can be accurately displayed and found, and it can be repaired in time to reduce the loss of deep-sea aquaculture.

[0047] The side of the interception net body 20 is provided with criss-cross reinforcing ribs 21. The top end of the interception net body 20 is provided with an upper net steel, and the bottom end of the interception net body 20 is provided with a lower net steel. The reinforcing ribs 21 are woven from high-strength fibers. By setting the reinforcing ribs 21, the strength of the interception net body 20 is increased. During actual production, the net body is woven on both sides of the upper net cable and the lower net cable and connected to form the interception net body 20.

[0048] The buoyancy component 18 is a floating cylinder. The material of the floating cylinder is high-density polyethylene. A through hole for the upper cable 22 to pass through is opened on the floating cylinder. The upper cable 22 is tied and connected to the upper net steel.

[0049] The first anchoring component 19 is a pile anchor or an anchor block. In this embodiment, the anchoring component is a pile anchor. The lower cable 23 is tied and connected to the lower net steel, and then the lower cable 23 is tied and connected to the pile anchor. The lower cable 23 is a steel wire cable, so as to achieve the purpose of opening the interception net body 20 and fixing the position of the interception net body 20.

[0050] The combined deep-sea and far-sea aquaculture cage further includes an underwater monitoring system. The underwater monitoring system includes an underwater detection device and a processor. The underwater detection device is installed on the cage 3 and the interception net body 20. The underwater detection device is connected to the processor, and the processor is connected to the water surface controller. Through the underwater monitoring system, the monitoring of the aquaculture process and information recording are realized. The underwater detection device is one or a combination of a temperature sensor, a salinity sensor, a pH value sensor, a dissolved oxygen sensor, and a camera.

[0051] Such as Figure 7As shown, the net cage 3 includes a net body 4, an upper net cover 5, a sea cucumber attachment base 7, a counterweight assembly 8 and a support tube 9; a net cover 5 is provided at the top opening of the net body 4, a support tube 9 is provided at the top edge of the net body 4, a sea cucumber attachment base 7 is provided at the bottom inner of the net body 4, a counterweight assembly 8 is provided at the bottom end of the net body 4, and the counterweight assembly 8 is fixed to the seabed under the action of its own gravity. A plurality of traction ropes 10 are symmetrically connected to the outside of the net body 4, and the ends of the traction ropes 10 are sewn on the side of the net body 4. Specifically, the ends of the traction ropes 10 are fit-sewn from the bottom to the top of the side of the net body 4, ensuring the balanced distribution of the traction force of the traction ropes 10 on the net cage 3. The counterweight assembly 8 at the bottom of the net body 4 is used to prop up the bottom of the cage 3 and firmly "lock" it on the seabed, which solves the problem that sea cucumbers cannot survive in high temperatures in summer. In addition, the seabed is rich in sea mud and seaweed microorganisms, which provide sea cucumbers with rich and diverse food, restore the living environment of wild sea cucumbers, and cultivate healthier and more nutritious sea cucumbers. In addition, the seabed current is slower than the sea surface surge. The cage 3 is located on the seabed, providing sea cucumbers with a more comfortable, stable and safe living space; a sea cucumber attachment base 7 is provided at the bottom of the net body 4. When in use, the sea cucumber attachment base 7 is spread flat on the seabed for sea cucumbers to attach and grow. At the same time, the sea cucumber attachment base 7 can also be used as a carrier of nutrients, and its interior can be filled with nutrients required for the growth of sea cucumbers. These nutrients are slowly released during the growth process of sea cucumbers and absorbed by sea cucumbers. By arranging a net cover 5 and a support tube 9 on the top of the net body 4, the two cooperate to float up, and the upper part of the net cage 3 is stretched open, and a traction rope 10 is arranged on the outside of the net body 4. The end of the traction rope 10 is connected to the water surface float 15. The traction rope 10 lifts the side of the net cage 3 and stretches it open, which can maintain the shape of the net cage 3 and ensure that the breeding space inside the net cage 3 is not deformed. When collecting sea cucumbers, the net cage 3 is lifted as a whole by the traction rope 10 connected to the water surface float 15, and the sea cucumber collection operation can be carried out.

[0052] The net body 4 is made of high-strength polyester, which is strong and durable. Ultra-high molecular weight polyethylene can also be used. The net cover 5 is made of ultra-high molecular weight polyethylene. The mesh size of the net body 4 and the net cover 5 is smaller than the volume of the sea cucumber, ensuring that the sea cucumber will not be washed to the outside of the net box 3. The net cover 5 uses an ultra-high molecular weight polyethylene net with a density lower than that of water, which can ensure that the net cover 5 floats without supporting the bottom, and a certain breeding space is formed inside the net box 3.

[0053] The sea cucumber attachment base 7 is a three-dimensional spacer fabric. The sea cucumber attachment base 7 is sewn to the inner bottom and side of the net body 4 through sewing threads. The structure of the three-dimensional spacer fabric is similar to a sandwich. It is a three-dimensional woven fabric formed by connecting a group of vertical yarns between two parallel fabric plane structures. Specifically, one side of the surface of this three-dimensional knitted spacer fabric is sparse and the other side is dense, with a thickness of about 3-6 mm. The three-dimensional spacer fabric is located at the inner bottom of the net cage 3, providing a soft and comfortable bedding for the sea cucumbers. In actual application, the three-dimensional spacer fabric located at the inner bottom of the net cage 3 is laid flat on the seabed, and the sea cucumbers attach to the three-dimensional spacer fabric and grow. Nutrients required for the growth of sea cucumbers can be filled inside the three-dimensional spacer fabric, and these nutrients are slowly released during the growth process of the sea cucumbers and absorbed by the sea cucumbers. Therefore, this three-dimensional spacer fabric is both the growth base fabric for sea cucumbers and the carrier of nutrients.

[0054] In actual application, a collection opening 6 for collecting sea cucumbers is reserved between the upper net cover 5 and the top of the net body 4. The collection opening 6 is usually set at the four corners for easy opening. The specific setting position can also be adjusted according to actual needs. The collection opening 6 can be closed by tying with a connecting rope, which has a relatively low overall cost. Other openable methods in the existing technology can also be used.

[0055] The counterweight assembly 8 is a counterweight anchor chain or a counterweight block. In this embodiment, the counterweight assembly 8 is a counterweight anchor chain, and the counterweight anchor chain is tied to the four bottom edges of the net body 4.

[0056] The mooring system 24 includes a first connecting rope 25, a second connecting rope 26, and a second anchoring assembly 27. The first connecting rope 25 is obliquely pulled outside the water surface floating body 15, and the end of the first connecting rope 25 is connected to the second anchoring assembly 27 located on the seabed. The second connecting rope 26 is connected to the outside of the positioning grid 12, and the second connecting rope 26 is connected to the second anchoring assembly 27. In this embodiment, the second anchoring assembly 27 is an anchor block. A vertical column is pre-embedded in the anchor block during casting, and a vertical column is formed at the top of the anchor block. One end of the first connecting rope 25 is fixedly connected to the anchor block, restricting the floating water surface floating body 15 within a certain range of movement. One end of the second connecting rope 26 is connected to the vertical column, which can tension the positioning grid 12 and lift it to a certain height above the seabed.

[0057] In summary, this combined deep-sea and far-sea aquaculture net cage has strong anti-wave ability, improves the stability of the aquaculture environment of the inner net cage 3, can make full use of the target sea area, reduces the operation cost of the fishing ground, increases the single production area, has good economy, and also realizes the monitoring and information recording of the aquaculture process within the sea area aquaculture area.
