Description

Technical Field

[0001] The present invention relates to the technical field of aquaculture cages, and in particular to a stable deep-sea aquaculture cage that is wind- and wave-resistant. Background Art

[0002] Deep-sea aquaculture cages are devices deployed in the deep sea for artificially cultivating seafood such as fish and shrimp. They are wind-resistant and stable. Various deep-sea aquaculture cages have been proposed in the prior art. For example, Chinese invention patent publication number CN116138196B proposes a deep-sea aquaculture cage that uses wave energy to generate electricity. This deep-sea aquaculture cage combines a butterfly-shaped floating body for wave energy generation and a flexible piezoelectric wave energy collector with the aquaculture cage. The butterfly-shaped floating body and the flexible piezoelectric wave energy collector provide power support for the aquaculture cage, solving the problem of power supply difficulties for deep-sea aquaculture cages. The butterfly-shaped floating body swings up and down with the waves, driving the power generation system to generate electricity. At the same time, the flexible piezoelectric wave energy collector generates electric potential based on the different pressure signals reflected by the wave fluctuations to generate electricity. The butterfly-shaped floating body and the flexible piezoelectric wave energy collector complement each other to achieve autonomous power supply for the aquaculture cage in the deep sea.

[0003] However, the above-mentioned deep-sea aquaculture cages that use wave energy to generate electricity, like other deep-sea aquaculture cages, cannot screen and separate the fish cultured therein according to their size. Mixing fish of varying sizes in the aquaculture cages will cause the smaller fish to grow slowly due to lack of feed, resulting in some fish not meeting the size standards but occupying the limited space and oxygen in the aquaculture cages, thereby reducing aquaculture efficiency. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a stable deep-sea aquaculture cage that is resistant to wind and waves and can effectively screen and separate fish with large differences in size during the entire aquaculture process and raise them separately, thereby improving the rate of fish reaching the standard size and aquaculture efficiency.

[0005] The present invention provides a stable deep-sea aquaculture cage that is resistant to wind and waves, including a box frame and a cage net. The cage net is arranged on the outer wall and bottom of the box frame, and the box frame supports the cage net; it also includes a pipe column, a crossbeam, a first partition net, a second partition net, and a third partition net. The pipe column is vertically arranged in the middle of the box frame, the inner ends of multiple crossbeams are connected to the pipe column, and the outer ends of multiple crossbeams are connected to the box frame. The first partition net is installed between the pipe column and the box frame, and the second partition net is installed between the pipe column and the box frame. The first partition net and the second partition net are respectively located on both sides of the pipe column. The first partition net and the second partition net divide the space inside the box frame into In the big fish area and the small fish area, the mesh of the partition net 2 is larger than the mesh of the partition net 1, the inner side of the partition net 3 is movably installed on the outer wall of the pipe column, the partition net 3 is located in the small fish area, the mesh of the partition net 3 is larger than the mesh of the partition net 1 and smaller than the mesh of the partition net 2, the outer side of the partition net 3 is in sliding contact with the inner wall of the box net, a driving component of the partition net 3 is arranged on the pipe column, and the driving component drives the partition net 3 to rotate around the axis of the pipe column; the fish in the box frame and the box net have a small difference in size in the early stage of growth, and can freely pass through the meshes of the partition net 1, the partition net 2 and the partition net 3, so that the fish are mixed and distributed in the area separated by the partition net 1 and the partition net 2. The fish are placed in the big fish area and the small fish area; in the middle and late stages of their growth, the size difference between the fish gradually increases, the smaller fish can pass through the meshes of the first, second and third partition nets, the larger fish can only pass through the mesh of the second partition net. Initially, the third partition net is close to the first partition net, and the driving component drives the third partition net to rotate around the pipe column from the first partition net to the second partition net in the small fish area, so that the third partition net can stop the larger fish and mix a small number of small fish to pass through the mesh of the second partition net and drive them into the big fish area. The third partition net is close to the second partition net, so that the big fish cannot pass through the first, second and third partition nets to return to the small fish area again. Since the smaller fish cannot compete with the larger fish, they are gathered from the meshes of the first, second and third partition nets to the small fish area, thereby achieving efficient separation of farmed fish according to size. By feeding feed differently to the large fish area and the small fish area, the growth of the fish in the small fish area is accelerated. In the later breeding process, the third partition net is moved back and forth many times, and the larger fish in the small fish area are driven into the large fish area many times, thereby achieving effective screening and separation of farmed fish according to size throughout the entire breeding process, so that fish with large size differences are raised separately, the body size compliance rate of farmed fish is improved, the breeding efficiency is improved, and the practicality is good.

[0006] Preferably, the driving assembly includes multiple bearings, multiple mounting rings, a motor and a driving shaft, the multiple bearings are sleeved on the outer wall of the pipe column, the multiple mounting rings are respectively sleeved on the outer rings of the multiple bearings, the inner side of the partition three is installed on the multiple mounting rings, the side wall of the pipe column facing the small fish area is provided with an arc-shaped opening, the motor one is installed on the top of the pipe column, the lower end of the output shaft of the motor one is connected to the upper end of the driving shaft, the driving shaft is coaxially mounted in the pipe column, and the lower end of the driving shaft is connected to the mounting ring through the arc-shaped opening of the pipe column; the partition three is rotatably mounted on the pipe column through multiple mounting rings and multiple bearings. When fish need to be separated on the outer wall, motor one drives the driving shaft to rotate, so that the driving shaft drives the mounting ring and the partition net three to move around the pipe column between the partition net one and the partition net two. When the partition net three moves from the partition net two to the partition net one, the smaller fish pass through the mesh of the partition net three and remain in the small fish area; when the partition net three moves from the partition net one to the partition net two, the partition net three intercepts the larger fish and drives them into the big fish area through the mesh of the partition net two. During the movement of the partition net three, the smaller fish pass through the mesh of the partition net three and remain in the small fish area, thereby realizing efficient driving of the partition net three, with a simple structure and good practicality.

[0007] Preferably, it also includes two feeding mechanisms, which feed the big fish area and the small fish area respectively. The feeding mechanism includes a mounting rod, a connecting rod 1, a connecting rod 2, a horizontal rod and a feed trough. The mounting rod is horizontally mounted on the middle outer wall of the pipe column, one end of the connecting rod 1 is hinged to the inner end of the mounting rod, one end of the connecting rod 2 is hinged to the outer end of the mounting rod, the inner end of the horizontal rod is hinged to the other end of the mounting rod, the middle of the horizontal rod is hinged to the other end of the connecting rod 2, the horizontal rod is horizontally arranged, the connecting rod 1 and the connecting rod 2 are parallelly arranged, a feed trough is arranged at the outer end of the horizontal rod, and the horizontal rod and the feed trough are arranged on the box-shaped frame. The lifting assembly drives the horizontal rod and the feed trough to rise and fall in the box-type frame; the mounting rod, connecting rod one and connecting rod two provide rotational support for the horizontal rod and the feed trough. When feeding, the lifting assembly lifts the horizontal rod and the feed trough out of the water. The staff puts different types and quantities of feed into the two feed troughs according to the difference between large fish and small fish. The lifting assembly lowers the horizontal rod and the feed trough into the water. Since the horizontal rod and the feed trough remain horizontal during the lifting process, the feed in the feed trough is scattered and falls into the marine environment through the box net, which reduces the waste of feed and pollution to the marine environment.

[0008] Preferably, the lifting assembly includes motor 2, a reel and a cable 1. Motor 2 is installed on the box-type frame through a bracket. The output shaft of motor 2 is provided with a reel. The upper end of cable 1 is reeled in the reel, and the lower end of cable 1 is connected to the horizontal rod. Motor 2 drives the reel to rotate. When the reel reels cable 1, cable 1 pulls the horizontal rod and the feed trough upward. When the reel releases cable 1, cable 1 sends the horizontal rod and the feed trough downward, thereby realizing the lifting and lowering of the horizontal rod and the feed trough. The structure is simple and the operation is simple.

[0009] Preferably, the two trough covers are also included, both of the feed troughs are semi-cylindrical, the axes of the two feed troughs are horizontally arranged, the upper end faces of the two feed troughs are provided with feeding and taking openings, the two trough covers are respectively rotatably capped on the feeding and taking openings of the two feed troughs, the two trough covers are respectively concentrically arranged with the two feed troughs, the two horizontal rods are respectively provided with rotating assemblies of the two trough covers, and the rotating assemblies drive the trough covers to open or cap and close the feeding and taking openings of the feed troughs; after the horizontal rods and the feed troughs are lifted out of the water surface, the rotating assemblies rotate the trough covers to open the feeding and taking openings of the feed troughs, the staff members throw the feed into the feed troughs, the rotating assemblies rotate the trough covers to close the feeding and taking openings of the feed troughs after the feeding is completed, the feed is prevented from being scattered and wasted due to the impact of seawater on the feed during the descending process of the feed troughs, the rotating assemblies rotate the trough covers to open the feeding and taking openings of the feed troughs after the feed troughs reach the set depth, and the fish enter the feed troughs to feed, thereby further reducing the feed waste.

[0010] Preferably, the rotating assembly comprises a half-toothed ring and a gear, the half-toothed ring is arranged on the outer wall of the trough cover, the gear is rotatably installed on the horizontal rod through a shaft rod, the gear is in meshing transmission with the half-toothed ring, a power assembly is installed on the horizontal rod, and the power assembly drives the gear to rotate; the power assembly drives the gear to rotate, the gear is in meshing transmission to drive the half-toothed ring to rotate, the half-toothed ring drives the trough cover to rotate on the feed trough, and the opening and closing of the feeding and taking opening of the feed trough are realized.

[0011] Preferably, the power assembly comprises a rotating shaft, a bevel gear one, a shaft rod one, a bevel gear two and a universal shaft, one end of the connecting rod two is rotatably arranged with the rotating shaft, the rotating shaft is connected with the outer end of the mounting rod, the bevel gear one is concentrically installed on the rotating shaft, the shaft rod one is rotatably installed on the connecting rod two, the other end of the shaft rod one is concentrically arranged with the bevel gear two, the bevel gear two is in meshing transmission with the bevel gear one, and the other end of the shaft rod one is in transmission connection with the shaft rod of the gear through the universal shaft; the rotating shaft is fixedly connected with the outer end of the mounting rod, the trough cover opens the feeding and taking opening of the feed trough when the horizontal rod and the feed trough are above the water surface, the connecting rod two rotates relative to the rotating shaft and the bevel gear one during the descending process of the horizontal rod and the feed trough, the connecting rod two drives the shaft rod one to synchronously rotate, the bevel gear two is in meshing transmission with the bevel gear one, thereby driving the shaft rod one to rotate, the shaft rod one drives the gear to rotate through the universal shaft, the gear meshes the half-toothed ring to drive the trough cover to rotate on the feed trough, the feeding and taking opening of the feed trough is opened after the feed trough reaches the set depth, and the linkage effect is good.

[0012] Preferably, it also includes two cylinders and two bevel gears three, the two rotating shafts are rotatably connected to the two mounting rods, the two cylinders are respectively installed on the two mounting rods, the two bevel gears three are concentrically installed on the telescopic rods of the two cylinders, and the two bevel gears three are aligned and meshed with the two bevel gears one; when the two trough covers are not needed to rotate on the two feed troughs, the telescopic rods of the two cylinders are retracted, so that the two bevel gears three are disengaged from the two bevel gears one, at this time, the two rotating shafts rotate under the drive of the two bevel gears one, so that the shaft rod one does not rotate, at this time the relative position of the trough cover and the feed trough remains stable, preventing the feed trough from opening during the lowering process; when the two trough covers need to rotate on the two feed troughs, the piston rods of the two cylinders are extended, so that the two bevel gears three are respectively meshed with the two bevel gears one, thereby locking the two rotating shafts, at this time the two rotating shafts drive the two bevel gears one to rotate, so that the shaft rod one rotates, and the trough cover rotates. By adjusting the extension and contraction time of the two cylinders, the take-out opening can be opened when the feed trough reaches the specified position, thereby achieving accurate control of the opening and closing of the two trough covers.

[0013] Preferably, it also includes two baffles and two spring sheets, and water permeability is provided on the two trough covers. One side of the two baffles is hinged to the inner walls of the two trough covers respectively, and the two baffles close the water permeability of the two trough covers respectively. One end of the two spring sheets is connected to the two baffles respectively, and the other end of the two spring sheets is connected to the two trough covers respectively. The elastic force of the two spring sheets presses the two baffles against the inner walls of the two trough covers respectively; the elastic force of the spring sheets presses the baffles against the inner walls of the trough covers to elastically close the water permeability. When the feed trough drops below the water surface, the water pressure pushes the baffles open, allowing seawater to enter the feed trough and the trough cover through the water permeability. By optimizing the position of the water permeability and the diversion effect of the baffles, the impact of seawater on the feed in the feed trough can be reduced. After the water pressure inside and outside the feed trough and the trough cover is balanced, the trough cover can be easily opened and closed.

[0014] The two ends of the cable are guided by two pulleys and are connected to the two anchor bodies respectively, and the two pulleys are rotatably mounted on both sides of the bottom of the box-shaped frame through the brackets; the counterweight block plays a counterweight role on the box-shaped frame through the cable two, the turntable and the cable winding shaft, thereby lowering the center of gravity of the box-shaped frame and making the box-shaped frame more stable. The shaft anchors the box-type frame. When the box-type frame is hit by wind and waves, the box-type frame drives the rope winding shaft to move to one side. At the same time, one end of the cable three is tightened and the other end is released. At the same time, the middle part of the cable three is wound around the rope winding shaft and rotates. The rope winding shaft drives the turntable to rotate, so that the turntable winds the cable two around the outer wall of the turntable and lifts the counterweight block, thereby achieving a buffering effect on the box-type frame and improving the box-type frame's ability to resist wind and waves. When the wind and waves decrease, the counterweight block moves downward under the action of gravity, so that the cable two pulls the turntable to rotate and reset, and the turntable drives the rope winding shaft to reset and rotate. The rope winding shaft resets the cable three, so that the two ends of the cable three return to an equal length state, thereby realizing automatic reset of the box-type frame.

[0015] Compared with the prior art, the beneficial effects of the present invention are: it can efficiently separate farmed fish according to their size, and by feeding feed to the large fish area and the small fish area differently, the growth of the fish in the small fish area is accelerated. In the later breeding process, the separation net is moved back and forth three times to drive the larger fish in the small fish area into the large fish area multiple times, thereby achieving effective screening and separation of farmed fish according to their size during the entire breeding process, so that fish with large size differences can be raised separately, thereby improving the rate of farmed fish reaching the standard size, improving breeding efficiency, and having good practicality.

[0031] The third separating net 7 is rotatably installed on the outer wall of the pipe column 3 through the plurality of mounting rings 9 and the plurality of bearings 8. The fish in the box-shaped frame 1 and the box net 2 have a small size difference in the initial growth stage and can freely pass through the meshes of the first separating net 5, the second separating net 6 and the third separating net 7, so that the fish are mixedly distributed in the large fish area and the small fish area separated by the first separating net 5 and the second separating net 6. The fish have a gradually increasing size difference in the middle and late growth stages. The fish with a small size can pass through the meshes of the first separating net 5, the second separating net 6 and the third separating net 7, and the fish with a large size can only pass through the mesh of the second separating net 6.

Embodiment

[0032] As Figures 7 to 11As shown, on the basis of Example 1 or Example 2, two feeding mechanisms are further included, and the two feeding mechanisms feed feed to the large fish area and the small fish area respectively. The feeding mechanism includes a mounting rod 12, a connecting rod 13, a connecting rod 2 14, a horizontal rod 15 and a feed trough 16.

A lifting assembly of a horizontal rod 15 and a feed trough 16 is provided on the box-type frame 1. The lifting assembly drives the horizontal rod 15 and the feed trough 16 to rise and fall in the box-type frame 1; the lifting assembly includes a second motor 17, a retractor 18 and a cable 19. The second motor 17 is installed on the box-type frame 1 through a bracket. The output shaft of the second motor 17 is provided with a retractor 18. The upper end of the cable 19 is retracted in the retractor 18, and the lower end of the cable 19 is connected to the horizontal rod 15; it also includes two trough covers 20. The two feed troughs 16 are both semi-cylindrical. The axes of the two feed troughs 16 are arranged horizontally. The upper end surfaces of the two feed troughs 16 are provided with a take-and-put port. The two trough covers 20 are respectively rotated to cover the two feed troughs 16. On the take-and-put port, two slot covers 20 are respectively arranged concentrically with the two feed troughs 16, and two rotating components of the slot covers 20 are respectively arranged on the two horizontal rods 15. The rotating components drive the slot covers 20 to open the take-and-put port of the feed trough 16 or close the cover buckle; the rotating component includes a half gear ring 21 and a gear 22. The half gear ring 21 is arranged on the outer wall of the slot cover 20, and the gear 22 is rotatably installed on the horizontal rod 15. The gear 22 is meshed with the half gear ring 21 for transmission. A power component is installed on the horizontal rod 15, and the power component drives the gear 22 to rotate; the power component includes a rotating shaft 23, a bevel gear 1 24, a shaft 1 25, a bevel gear 2 26 and a universal shaft 27. The rotating shaft 23 is rotatably set at one end of the connecting rod 2 14. The rotating shaft 23 is connected to the outer end of the mounting rod 12, and the bevel gear 1 24 is concentrically mounted on the rotating shaft 23. The shaft rod 1 25 is rotatably mounted on the connecting rod 2 14. One end of the shaft rod 1 25 is concentrically provided with a bevel gear 2 26. The bevel gear 2 26 is meshed with the bevel gear 1 24 for transmission. The other end of the shaft rod 1 25 is connected to the shaft of the gear 22 through a universal joint 27. The machine also includes two cylinders 28 and two bevel gears 3 29. The two rotating shafts 23 are respectively rotatably connected to the two mounting rods 12. The two cylinders 28 are respectively mounted on the two mounting rods 12. The two bevel gears 3 29 are respectively concentrically mounted on the telescopic rods of the two cylinders 28. The two bevel gears 3 29 are respectively aligned and meshed with the two bevel gears 1 24.The device further includes two baffles 30 and two spring leaves 31. Both trough covers 20 are provided with water-permeable openings. One side of each baffle 30 is hingedly connected to the inner walls of each trough cover 20. The two baffles 30 respectively seal the water-permeable openings of each trough cover 20. One end of each spring leaf 31 is connected to each baffle 30, and the other end of each spring leaf 31 is connected to each trough cover 20. The elastic force of the two spring leaves 31 presses the two baffles 30 against the inner walls of each trough cover 20.

[0033] The mounting rod 12, the connecting rod 13 and the connecting rod 2 14 provide rotational support for the horizontal rod 15 and the feeding trough 16. When feeding, the motor 2 17 drives the reel 18 to rotate, and the reel 18 reels the cable 19. The cable 19 pulls the horizontal rod 15 and the feeding trough 16 upward, and lifts the horizontal rod 15 and the feeding trough 16 out of the water. The half gear ring 21 engages the gear 22 to rotate the trough cover 20 so that the feeding trough 16 is opened. The staff puts different types and quantities of feed into the two feeding troughs 16 according to the difference between large fish and small fish. The two cylinders 2 The piston rod of 8 extends, causing the two bevel gears 3 29 to mesh with the two bevel gears 1 24 respectively, thereby locking the two rotating shafts 23. The retractor 18 releases the cable 19, and the cable 19 sends the horizontal rod 15 and the feed trough 16 downward. During the process of the horizontal rod 15 and the feed trough 16 descending, the connecting rod 2 14 rotates relative to the rotating shaft 23 and the bevel gear 1 24, and the connecting rod 2 14 drives the shaft 1 25 to rotate synchronously. The bevel gear 2 26 meshes with the bevel gear 1 24, thereby driving the shaft 1 25 to rotate. The shaft 1 25 drives the gear 22 to rotate through the universal joint 27. The gear 22 meshes with the half gear ring 21 to drive the trough cover 20 to rotate on the feed trough 16, so that the feed trough 16 is sealed with its access opening by the trough cover 20 before it enters the seawater. The two cylinders 28 contract to disengage the two bevel gears 3 29 from the two bevel gears 1 24. As the feed trough 16 descends, the water pressure pushes the baffle 30 open, allowing seawater to enter the feed trough 16 and the trough cover 20 through the water-permeable opening. By optimizing the position of the water-permeable opening and the diversion effect of the baffle 30, the impact of seawater on the feed in the feed trough 16 can be reduced. When the feed trough 16 reaches the set depth, the two cylinders 28 stretches to make the two bevel gears three 29 and the two bevel gears one 24 mesh again, thereby driving the two trough covers 20 to rotate and open the access opening of the feed trough 16. Since the horizontal rod 15 and the feed trough 16 remain horizontal during the lifting process, and the trough cover 20 closes and covers the access opening of the feed trough 16, it prevents the feed in the feed trough 16 from being scattered and falling into the marine environment through the box net 2, causing feed waste and pollution to the marine environment. After feeding is completed, the two retractors 18 reel in the rope one 19 to lift the two feed troughs 16 above the water surface to prepare for the next feeding. Example

[0034] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 12 As shown, on the basis of Example 1 or Example 2, it also includes a rope winding shaft 32, a turntable 33, a second cable 34, a counterweight 35, a third cable 36, two pulleys 37 and two anchor bodies 38. The rope winding shaft 32 is rotatably installed at the bottom of the box-type frame 1, and a turntable 33 is concentrically arranged at one end of the rope winding shaft 32. One end of the second cable 34 is connected to the outer edge of the turntable 33, and the lower end of the second cable 34 is connected to the counterweight 35. The middle part of the third cable 36 is wound around the rope winding shaft 32. The two ends of the third cable 36 are guided by two pulleys 37 and are respectively connected to the two anchor bodies 38. The two pulleys 37 are rotatably installed on both sides of the bottom of the box-type frame 1 through brackets.

[0035] The counterweight block 35 plays a counterweight role on the box frame 1 through the second cable 34, the turntable 33 and the rope winding shaft 32, lowering the center of gravity of the box frame 1 and making the box frame 1 more stable. The two anchor bodies 38, the third cable 36 and the rope winding shaft 32 anchor the box frame 1. When the box frame 1 is hit by wind and waves, the box frame 1 drives the rope winding shaft 32 to move to one side, and at the same time, one end of the third cable 36 is tightened and the other end is released. At the same time, the middle part of the third cable 36 is wound around the rope winding shaft 32 to rotate, and the rope winding shaft 32 drives the turntable 33 rotates, so that the turntable 33 winds the second cable 34 around the outer wall of the turntable 33 and lifts the counterweight 35, thereby achieving a buffering effect on the box-type frame 1 and improving the wind and wave resistance of the box-type frame 1. When the wind and waves decrease, the counterweight 35 moves downward under the action of gravity, so that the second cable 34 pulls the turntable 33 to rotate and reset, and the turntable 33 drives the rope winding shaft 32 to reset and rotate, and the rope winding shaft 32 resets the third cable 36, so that the two ends of the third cable 36 return to an equal length state, thereby realizing automatic reset of the box-type frame 1.

[0036] like Figures 1 to 12As shown, the present invention is a wind and wave resistant stable deep-sea aquaculture cage. When it is working, first, the fish in the box frame 1 and the cage net 2 have a small difference in size in the early stage of growth, and can freely pass through the meshes of the partition net 1 5, the partition net 2 6 and the partition net 3 7, so that the fish are mixed and distributed in the large fish area and the small fish area separated by the partition net 1 5 and the partition net 2 6; then, in the middle and late stages of growth, the size difference of the fish gradually increases, and the smaller fish can pass through the meshes of the partition net 1 5, the partition net 2 6 and the partition net 3 7, while the larger fish can only pass through the meshes of the partition net 2 6. Initially, the fish in the partition net 3 7 are separated by the meshes of the partition net 1 5, the partition net 2 6 and the partition net 3 7. When the filter is close to the first screen 5, the motor 10 drives the driving shaft 11 to rotate, so that the driving shaft 11 drives the third screen 7 to rotate around the pipe column 3 from the first screen 5 to the second screen 6 in the small fish area through the mounting ring 9, so that the third screen 7 can intercept the larger fish and mix a small number of small fish to drive them through the mesh of the second screen 6 into the large fish area. The third screen 7 is close to the second screen 6, so that the large fish cannot pass through the first screen 5, the second screen 6 and the third screen 7 to return to the small fish area again. The smaller fish in the large fish area cannot compete with the larger fish, so they pass through the first screen 5, the second screen 6 and the third screen 7. The mesh of 7 gathers into the small fish area, realizing efficient separation of farmed fish according to their size, and then feeds are fed into the large fish area and the small fish area respectively through the two feeding troughs 16, thereby accelerating the growth of the fish in the small fish area. In the later stage of breeding, the separation net 3 7 moves back and forth many times, driving the larger fish in the small fish area into the large fish area many times, realizing effective screening and separation of farmed fish according to their size during the entire breeding process. Finally, when the box-type frame 1 is impacted by wind and waves, the box-type frame 1 drives the rope shaft 32 to move to one side, and at the same time, one end of the cable 36 is tightened and the other end is released. At the same time, the cable 3 The middle part of 36 is wound around the rope winding shaft 32 and rotates, and the rope winding shaft 32 drives the turntable 33 to rotate, so that the turntable 33 winds the second cable 34 around the outer wall of the turntable 33 and lifts the counterweight block 35, which cushions the box-type frame 1 and improves the wind and wave resistance of the box-type frame 1. When the wind and waves decrease, the counterweight block 35 moves downward under the action of gravity, so that the second cable 34 pulls the turntable 33 to rotate and reset, and the turntable 33 drives the rope winding shaft 32 to reset and rotate, and the rope winding shaft 32 resets the third cable 36, so that the two ends of the third cable 36 return to the same length state, and the box-type frame 1 is automatically reset.

[0037] The main functions achieved by the present invention are:

[0038] 1. It can effectively screen and separate fish with large size differences during the entire breeding process and raise them separately, thereby improving the body size compliance rate and breeding efficiency of farmed fish;

[0039] 2. It can realize feeding at a fixed depth and reduce feed waste and pollution to the marine environment;

[0040] 3. The anchoring system with buffering effect improves the ability to resist wind and waves and is more stable;

[0041] 4. The feed trough is closed during lifting process, avoiding feed scattering and waste.

[0042] The installation mode, connection mode or setting mode of the anti-rough sea stable type deep sea aquaculture net cage is common mechanical mode, as long as the beneficial effects can be achieved, and the implementation can be carried out. The box type frame 1, the box net 2, the partition net 1 5, the partition net 2 6, the partition net 3 7, the bearing 8, the motor 1 10, the driving shaft 11, the feed trough 16, the motor 2 17, the winder 18, the cable 1 19, the half tooth ring 21, the gear 22, the rotating shaft 23, the bevel gear 1 24, the shaft rod 1 25, the bevel gear 2 26, the universal shaft 27, the air cylinder 28, the bevel gear 3 29, the spring sheet 31, the rotating disc 33, the cable 2 34, the cable 3 36, the pulley 37, the anchor body 38 are purchased on the market, and the technical personnel in the industry only need to install and operate according to the attached instruction manual, without the creative labor of the technical personnel in the field.

[0043] The above is only the preferred embodiment of the present application, it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, these improvements and modifications should also be considered as the protection scope of the present application.
