Description

Technical Field

[0001] This invention relates to the field of deep-sea aquaculture equipment technology, specifically to a self-balancing device for deep-sea tuna aquaculture cages resistant to wind and waves. Background Technology

[0002] Tuna are marine fish belonging to the order Scombroids, family Tunaidae. They have slender bodies, a dark blue-black back, and a silvery-white belly. They are very active fish, capable of rapid swimming. Tuna flesh is delicious, rich in protein, low in fat, and abundant in vitamins, giving it high economic and edible value. Tuna fishing has a long history in some parts of the world; however, large-scale commercial open-field tuna farming has led to a decline in wild tuna populations and increased difficulty in obtaining them. As a high-value fish, tuna farming methods are gradually shifting from traditional catch-and-holding to deep-sea cage culture. The complex deep-sea environment, with typhoons and strong waves, can cause cage structures to deform or even disintegrate. Therefore, deep-sea cage culture nets must be able to withstand currents and waves.

[0003] Existing technologies offer numerous technical means for deep-sea aquaculture. For example, prior art KR102676425B1 discloses a floating fish cage system for high seas using a floating offshore wind turbine. This invention involves installing a submerged, suspended fish cage aquaculture device on a floating offshore wind turbine located above the sea surface, with a floating structure. More specifically, a guide column extending to a predetermined depth into the seawater is connected and installed on the central side of the central support of the wind turbine tower, which is positioned in the center of the floating structure. This guide column allows the fish cage aquaculture device to sink into the seawater or float to the surface. A container is installed in the internal space at the bottom of the tower. The invention relates to a submerged floating offshore cage aquaculture device with a sinking and suspending unit and a feed supply device. Inside the guide column, a feed supply pipe for feeding the sinking feed into the upper part of the cage aquaculture device is set in a double-pipe configuration according to the sinking or suspending position of the cage aquaculture device. This invention is a sinking floating offshore cage aquaculture device using a floating offshore wind turbine, which can safely and efficiently raise high-value fish species and adult fish such as bluefin tuna. However, the device still has room for improvement in reducing cage swaying to reduce collision damage to farmed fish. Deep-sea aquaculture requires ensuring the stability of the aquaculture equipment and the survival rate of farmed organisms. Summary of the Invention

[0004] The purpose of this invention is to provide a self-balancing device for deep-sea tuna farming cages that are resistant to wind and waves, ensuring the dynamic stability of the farming cages, actively adjusting buoyancy and counterweight, keeping the farming cages in a stable state under different sea conditions, resulting in high quality and survival rate of farmed organisms, and a low probability of damage to farmed organisms during the farming process.

[0005] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution: a self-balancing device for deep-sea tuna aquaculture cages resistant to wind and waves, comprising an aquaculture cage, the aquaculture cage having first rings spaced vertically, the first rings being connected by second connecting rods, a support column in the middle of the aquaculture cage, and first connecting rods connected to the first rings being arranged around the sides of the support column, the first connecting rods and the first rings being hollow and interconnected, and a first sphere being built into the first connecting rods and the first rings. The first sphere fills the hollow space of the first connecting rods and the first rings, and the first sphere can be displaced under the drive of force, the first sphere being a solid structure or a hollow structure with an internal medium. The present invention features a cylindrical net cage structure formed by the connection of a first ring and a second connecting rod, which exhibits outstanding resistance to wind and waves in deep-sea environments. By installing a gravity-supported column in the middle of the net cage, the overall center of gravity of the net cage is lowered, reducing the overturning moment caused by wind and waves. In cases of high wave height, the gravity-supported column in the middle helps reduce the overall tilt angle of the net cage. When the net cage tilts, the first connecting rod and the first sphere inside the first ring adjust the gravity distribution of the first connecting rod and the first ring through displacement, helping the net cage to return to a horizontal state. Furthermore, the connection between the support column in the middle of the net cage and the first connecting rod and the first ring strengthens the structural strength of the entire aquaculture net cage. When water flows through the aquaculture net cage, the contact between the water flow and the support column, the first connecting rod, and the first ring expands the fluid contact, helping to form eddies around the structure, promoting water exchange inside and outside the aquaculture net cage, and preventing the accumulation of excrement.

[0006] According to one embodiment of the present invention, a first spring is provided inside the end of the first connecting rod adjacent to the support column. One end of the first spring is connected to the support column, and the other end is connected to a counterweight column with a rotating structure. The counterweight column can move inside the first connecting rod. The counterweight column is made of metal and has a certain weight. When the aquaculture net cage is stable in the water, the counterweight column is positioned close to the support column without displacement, which can help the support column lower the overall center of gravity of the net cage. When the aquaculture net cage tilts, such as when the net cage tilts at ≥5°, the counterweight column slides along the guide rail due to the shift in the center of gravity, pushing the surrounding first spheres to roll in the opposite direction of the tilt, generating a reverse restoring torque to counteract the overturning force of wind and waves, achieving efficient anti-overturning adjustment. Through the dynamic response mechanism, the stability of the aquaculture net cage under complex sea conditions is significantly improved.

[0007] According to one embodiment of the present invention, at least two first ring bodies are connected to a second connecting rod to form a net cage frame, and a net is laid on the net cage frame. The net cage frame constructed by the first ring bodies has a cylindrical structure without sharp edges, allowing water to flow around it. Regardless of the direction of the water flow, the cylindrical net cage is subjected to uniform force. High-speed fish such as tuna prefer circular swimming paths, and the cylindrical structure reduces collision damage, achieving the effect of adapting to fish behavior.

[0008] According to one embodiment of the present invention, auxiliary components capable of displacement relative to the support column are provided at both the upper and lower ends of the support column. The support column has holes at both ends, and each auxiliary component includes a second auxiliary rod with one end disposed within the hole, and a first auxiliary plate at the other end of the second auxiliary rod. The second auxiliary rod within the hole has a protruding portion, and a retaining ring is provided at the hole port of the support column. The retaining ring and the protruding portion limit the displacement distance of the end of the second auxiliary rod, preventing it from detaching from the hole. The second auxiliary rod can move vertically relative to the support column, and the first auxiliary plate offsets wave impact by floating up and down, reducing the overall swaying of the net cage. The first auxiliary plate is linked with the bottom support column to form a "floating-counterweight" dual-mode balance system. This arrangement of auxiliary components in the vertical direction of the support column further enables the upper first auxiliary plate to push the surface oxygen-rich water to sink, and the lower first auxiliary plate to drive the bottom excrement to rise, promoting water circulation and excrement discharge. More importantly, the first auxiliary plate can buffer wave noise and alleviate the stress response of sensitive fish such as tuna.

[0009] According to one embodiment of the present invention, a second auxiliary plate is provided between the first auxiliary plate and the support column. The first auxiliary plate and the second auxiliary plate are connected by a first auxiliary rod, which is fixedly connected to the second auxiliary plate and movably connected to the first auxiliary plate. The second auxiliary plate can work in conjunction with the first auxiliary plate to enhance the effect of counteracting wave impact and reducing noise.

[0010] According to one embodiment of the present invention, a first float is provided around the outside of the aquaculture cage, and a first counterweight is connected to the bottom of the first float via a first rope. The first float structure around the aquaculture cage can absorb wave impact and distribute the concentrated load to the entire first float structure, reducing the deformation of the aquaculture cage frame. In terms of external floating objects, algae, and attached substances, the presence of the first float can form a pollution barrier outside the aquaculture cage.

[0011] A photovoltaic panel and a controller are installed on the first float. The controller has a control chip, a battery, a signal transceiver, a wireless module, a locator, sensor components, an acoustic and optical unit, etc. The sensor components include, but are not limited to, temperature sensors, humidity sensors, and wind direction and speed sensors. A flow velocity and direction meter is installed at the bottom of the first float. These monitoring sensors or devices are all connected to the controller for data acquisition and transmission to the land control room / mobile terminal, etc., to monitor the aquaculture environment and record aquaculture environment data.

[0012] According to one embodiment of the present invention, the first float is equipped with at least one winding machine, which is connected to the aquaculture cage via a winding rope. A lifting ring is provided on the first ring of the aquaculture cage, and the winding rope is connected to the lifting ring. Generally, there are two or three winding machines to ensure stable hoisting of the aquaculture cage. The start and stop of the winding machines are controlled by a controller, which adjusts the position of the aquaculture cage according to different sea conditions. For example, during typhoon weather, the winding machines can be controlled to lower the aquaculture cage to a position 50m-200m below the water surface to avoid wind and waves. For excessive tilting of the aquaculture cage, the tilt angle can be actively controlled by the winding machines.

[0013] According to one embodiment of the present invention, a counterweight is connected to the bottom of the aquaculture cage via a first rope. The counterweight increases the weight of the aquaculture cage, enabling it to overcome buoyancy and preventing the cage from bobbing up and down due to buoyancy. This ensures the cage is at a suitable aquaculture depth, providing a stable living environment for the cultured organisms. Under the influence of water flow and waves, the aquaculture cage is prone to swaying and displacement. The counterweight lowers the center of gravity of the cage, increasing its stability, reducing swaying and displacement, minimizing disturbance to the cultured organisms, and also helping to protect the cage structure and extend its service life.

[0014] According to one embodiment of the present invention, a second counterweight is connected to the bottom of the counterweight via a first rope. The counterweight, suspended in the water, allows the aquaculture cage to maintain a specific depth in the water, while the second counterweight at the bottom further fixes the horizontal position of the aquaculture cage, preventing it from moving excessively horizontally with the water flow. The combination of these two components allows for more precise positioning of the aquaculture cage in the ideal aquaculture area, meeting the specific requirements of different aquaculture species for environmental conditions such as water depth and flow.

[0015] According to one embodiment of the present invention, a second counterweight is placed at the bottom of the water body, and a third counterweight is provided on one side of the second counterweight. One end of a first rope connected to the counterweight is connected to the bottom of the counterweight, and the other end passes through the second and third counterweights in sequence to connect to a first float. When encountering large waves, the surface and middle layers of the water fluctuate greatly. The counterweight suspended in the water at the main water layer affected by the waves can play a balancing and buffering role, reducing the swaying and rocking of the aquaculture cage. At the same time, the second and third counterweights at the bottom of the water body serve as a stable foundation, providing additional tension and resistance to prevent the aquaculture cage from being lifted or washed away by the waves. The two work together to significantly enhance the cage's resistance to wind and waves. In daily use, the presence of the first float can relatively straighten the first rope, improving the stability of the counterweight in the water, thereby ensuring the stability of the aquaculture cage in the water.

[0016] Compared with existing technologies, the beneficial effects of this invention are as follows: The first ring body and the second connecting rod of this invention form a cylindrical net cage structure, which has outstanding resistance to wind and waves in deep-sea environments. By setting gravity-supported columns in the middle of the net cage, the overall center of gravity of the net cage is lowered, reducing the overturning moment caused by wind and waves. When the aquaculture net cage tilts, the counterweight column slides along the guide rail due to the shift in the center of gravity, pushing the surrounding first spheres to roll in the opposite direction of the tilt, generating a reverse restoring moment to counteract the overturning force of wind and waves, achieving efficient anti-overturning adjustment. This dynamic response mechanism significantly improves the stability of the aquaculture net cage under complex sea conditions. The solution of this invention can ensure the dynamic stability of the aquaculture net cage, actively adjust buoyancy and counterweight, keep the aquaculture net cage in a stable state under different sea conditions, resulting in high quality and survival rate of cultured organisms and a low probability of damage to cultured organisms during the aquaculture process.

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] The concepts involved in this application will first be described with reference to the accompanying drawings. It should be noted that the following descriptions of various concepts are only for the purpose of making the content of this application easier to understand and do not constitute a limitation on the scope of protection of this application; furthermore, the embodiments and features in the embodiments of this application can be combined with each other unless otherwise specified. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] Example 1:

[0034] As shown in the attached figure Figure 1 -Appendix Figure 11As shown, the self-balancing device for deep-sea tuna aquaculture cages that resists wind and waves provided by the present invention includes an aquaculture cage 20. The aquaculture cage 20 has first rings 21 arranged at intervals between the upper and lower parts. The first rings 21 are connected by a second connecting rod 23. A support column 25 is provided in the middle of the aquaculture cage 20. A first connecting rod 22 connected to the first rings 21 is arranged around the side of the support column 25. The first connecting rod 22 and the first rings 21 are hollow and connected inside. A first sphere 29 is built into the first connecting rod 22 and the first rings 21. The present invention provides a cylindrical net cage structure formed by connecting the first ring body 21 and the second connecting rod 23. This structure exhibits outstanding resistance to wind and waves in deep-sea environments. By setting a gravity-supporting column 25 in the middle of the net cage, the overall center of gravity of the net cage is lowered, reducing the overturning moment caused by wind and waves. In cases of high wave height, the gravity-supporting column 25 in the middle helps reduce the overall tilt angle of the net cage. When the net cage tilts, the first connecting rod 22 and the first ring body 21, with their built-in first sphere 29, adjust the gravity distribution of the first connecting rod 22 and the first ring body 21 through displacement, helping the net cage to return to a horizontal state. Furthermore, the connection between the support column 25 in the middle of the net cage and the first connecting rod 22 and the first ring body 21 strengthens the structural strength of the entire aquaculture net cage 20. When water flows through the aquaculture net cage 20, the contact between the water flow and the support column 25, the first connecting rod 22, and the first ring body 21 expands the fluid contact, helping the fluid to form eddies around the structure, promoting water exchange inside and outside the aquaculture net cage 20, and preventing the accumulation of excrement.

[0035] The first sphere 29 fills the hollow space between the first connecting rod 22 and the first ring 21. The first sphere 29 can be displaced under the drive of force. The first sphere 29 is a solid structure or a hollow structure with an internal medium.

[0036] A first spring 27 is installed inside the end of the first connecting rod 22 adjacent to the support column 25. One end of the first spring 27 is connected to the support column 25, and the other end is connected to a counterweight column 28 with a rotating structure. The counterweight column 28 can move inside the first connecting rod 22. The counterweight column 28 is made of metal and has a certain weight. When the aquaculture net cage 20 is stable in the water, the counterweight column 28 is positioned close to the support column 25 without displacement, which can help the support column 25 lower the overall center of gravity of the net cage. When the aquaculture net cage 20 tilts, such as when the net cage tilts at a tilt of ≥5°, the counterweight column 28 slides along the guide rail due to the shift in the center of gravity, pushing the surrounding first spheres 29 to roll in the opposite direction of the tilt, generating a reverse restoring torque to counteract the overturning force of wind and waves, achieving efficient anti-overturning adjustment. Through the dynamic response mechanism, the stability of the aquaculture net cage 20 under complex sea conditions is significantly improved. Please refer to the attached diagram for the principle diagram. Figure 12 As shown.

[0037] At least two first ring bodies 21 are connected to the second connecting rod 23 to form a net cage frame, and a net 24 is laid on the net cage frame. The net cage frame constructed by the first ring bodies 21 is a cylindrical structure without sharp edges, allowing water to flow around it. Regardless of the direction of the water flow, the cylindrical net cage is subjected to uniform force. High-speed fish such as tuna prefer circular swimming paths, and the cylindrical structure reduces collision damage, achieving the effect of adapting to fish behavior.

[0038] The support column 25 is equipped with auxiliary components 60 at both its upper and lower ends, which are capable of displacement relative to the support column 25. The support column 25 has holes at both ends. Each auxiliary component 60 includes a second auxiliary rod 63 with one end inside the hole, and a first auxiliary plate 61 at the other end. The second auxiliary rod 63 has a protruding portion inside the hole, and a retaining ring is located at the hole port of the support column 25. The retaining ring and the protruding portion limit the displacement distance of the end of the second auxiliary rod 63, preventing it from detaching from the hole. The second auxiliary rod 63 can move vertically relative to the support column 25. The first auxiliary plate 61 floats up and down to counteract wave impact, reducing the overall swaying of the cage. The first auxiliary plate 61 is linked with the bottom support column 25 to form a "floating-counterweight" dual-mode balance system. The arrangement of auxiliary components 60 in the vertical direction of the support column 25 further enables the upper first auxiliary plate 61 to push the surface oxygen-rich water to sink, and the lower first auxiliary plate 61 to drive the bottom excrement to rise, promoting water circulation and excrement discharge. More importantly, the first auxiliary plate 61 can buffer wave noise and alleviate the stress response of sensitive fish such as tuna.

[0039] A second auxiliary plate is provided between the first auxiliary plate 61 and the support column 25. The first auxiliary plate 61 and the second auxiliary plate are connected by a first auxiliary rod 62. The first auxiliary rod 62 is fixedly connected to the second auxiliary plate, but movably connected to the first auxiliary plate 61. The second auxiliary plate works in conjunction with the first auxiliary plate 61 to enhance the effect of offsetting wave impact and reducing noise.

[0040] Both the first auxiliary plate 61 and the second auxiliary plate have through holes on their surfaces. These through holes can be umbrella-shaped or circular, etc. A rubber plate 64 is arranged around the side of the first auxiliary rod 62 between the first auxiliary plate 61 and the second auxiliary plate. The first auxiliary plate 61 has an assembly through hole for the first auxiliary rod 62 to enter and exit, and the upper end of the first auxiliary rod 62 extending out of the assembly through hole has a protrusion to prevent the first auxiliary rod 62 from detaching from the first auxiliary plate 61. The through holes are used to achieve wave reduction and noise reduction effects. When the first and second auxiliary plates move up and down, the fluid can change its flow path through the through holes to form a flow direction in the direction of the axis of the support column 25. This helps to improve the balance of the aquaculture cage 20 in the water and reduce its tilt angle.

[0041] The aquaculture cage 20 is provided with a first float 10 surrounding the aquaculture cage 20. The bottom of the first float 10 is connected to a first counterweight 13 by a first rope 30. The structure of the first float 10 surrounding the aquaculture cage 20 can absorb the impact of waves and distribute the concentrated load to the entire structure of the first float 10, reducing the deformation of the aquaculture cage 20 frame. In terms of external floating objects, algae, and attached substances, the presence of the first float 10 can form a pollution barrier outside the aquaculture cage 20.

[0042] A photovoltaic panel 14 and a controller 12 are provided on the first float 10. The controller 12 has a control chip, a battery, a signal transceiver, a wireless module, a locator, sensor components, an acoustic and optical unit, etc. The sensor components include, but are not limited to, temperature sensors, humidity sensors, and wind direction and speed sensors. A flow velocity and flow direction meter is provided at the bottom of the first float 10. These monitoring sensors or devices are all connected to the controller 12 for data acquisition and transmission to the land control room / mobile terminal, etc., to monitor the aquaculture environment and record aquaculture environment data.

[0043] The first float 10 is equipped with at least one winding machine 11, which is connected to the aquaculture cage 20 via a winding rope. The first ring 21 of the aquaculture cage 20 is equipped with a lifting ring, to which the winding rope is connected. Generally, there are two or three winding machines 11 to ensure stable hoisting of the aquaculture cage 20. The start and stop of the winding machines 11 are controlled by a controller 12, which adjusts the position of the aquaculture cage 20 according to different sea conditions. For example, during typhoon weather, the winding machines 11 can be used to lower the aquaculture cage 20 to a position 50m-200m below the water surface to avoid wind and waves. For excessive tilting of the aquaculture cage 20, the winding machines 11 can actively control the tilt angle of the aquaculture cage 20.

[0044] A counterweight 40 is connected to the bottom of the aquaculture cage 20 via a first rope 30. The counterweight 40 increases the weight of the aquaculture cage, helping it overcome buoyancy and preventing it from bobbing up and down. This ensures the cage is at a suitable depth, providing a stable living environment for the cultured organisms. Under the influence of water currents and waves, the aquaculture cage 20 is prone to swaying and displacement. The counterweight 40 lowers the center of gravity of the cage, increasing its stability, reducing swaying and displacement, minimizing disturbance to the cultured organisms, and also helping to protect the structure of the cage and extend its service life.

[0045] The bottom of the counterweight 40 is connected to a second counterweight 50 via a first rope 30. The counterweight 40 is suspended in the water to maintain the aquaculture cage 20 at a specific depth in the water, while the second counterweight 50 at the bottom of the water can further fix the horizontal position of the aquaculture cage 20 and prevent it from moving excessively in the horizontal direction with the water flow. The combination of the two can more accurately position the aquaculture cage in the ideal aquaculture area and meet the specific requirements of different aquaculture species for environmental conditions such as water depth and water flow.

[0046] The second counterweight 50 is placed at the bottom of the water surface, and a third counterweight 51 is located on one side of the second counterweight 50. One end of the first rope 30, which is connected to the counterweight 40, is connected to the bottom of the counterweight 40, and the other end passes through the second counterweight 50 and the third counterweight 51 to connect to the first float 52. When encountering large waves, the surface and middle layers of the water fluctuate greatly. The counterweight 40, suspended in the water, can play a balancing and buffering role in the main water layer affected by the waves, reducing the swaying and rocking of the aquaculture cage 20. At the same time, the second counterweight 50 and the third counterweight 51 at the bottom of the water form a stable foundation, providing additional tension and resistance to prevent the aquaculture cage 20 from being lifted or washed away by the waves. The two work together to significantly enhance the cage's resistance to wind and waves. In daily use, the presence of the first float 52 can relatively straighten the first rope 30, improving the stability of the counterweight 40 in the water and thus ensuring the stability of the aquaculture cage 20 in the water.

[0047] Example 2:

[0048] This embodiment is a further optimized solution based on embodiment 1, as shown in the appendix. Figure 1 Appendix Figure 7 As shown, the counterweight 40 is a rotating structure with a concave cylindrical hole at its upper end and an extension post 41 at its bottom. The extension post 41 has a through hole in its middle, which communicates with the cylindrical hole of the counterweight 40. A first side tube 42 is arranged around the extension post 41 and communicates with the through hole in its middle.

[0049] The upper part of the counterweight 40 is surrounded by small holes, which are used to connect with the first rope 30. In practical applications, in order to avoid the first rope 30 from breaking due to friction between the counterweight 40 and the first rope 30, the number of first ropes 30 and counterweight 40 connected is more than two, so as to ensure the effective connection between the counterweight 40 and the aquaculture net cage 20.

[0050] The counterweight 40 can lower the center of gravity of the aquaculture cage 20, increase its stability, reduce the degree of swaying and displacement, reduce disturbance to the cultured organisms, and at the same time help protect the structure of the aquaculture cage 20 and extend its service life. The design of setting it as a rotating body structure with a through opening in the middle and an extension column 41 at the bottom allows water to flow through from top to bottom. The water flows down along the through opening, directs the flow to form a vertical flow, and some of the fluid is discharged outward through the first side pipe 42, reducing the lateral turbulence that causes the aquaculture cage to drift.

[0051] Example 3:

[0052] This embodiment is a further optimized solution based on embodiment 1, as shown in the appendix. Figure 8 As shown, the first float 10 includes multiple floats constructed to form a polygonal structure, such as a hexagonal or octagonal structure, surrounding the periphery of the aquaculture cage 20. The floats are preferably made of high-density polyethylene (HDPE) with a foamed polyurethane core layer to ensure buoyancy.

[0053] Based on the polygonal structure constructed from floating boards, guardrails are installed. Guardrails are installed on the side of each floating board closest to the aquaculture cage. Adjacent guardrails are reinforced by binding them together with straps or wires.

[0054] Several buoys are set at the bottom of the float plate. The buoys need to be evenly spaced to avoid uneven buoyancy distribution.

[0055] On one side of the aquaculture cage 20 adjacent to the floating plate, there is a first plate 15. The first plates 15 are arranged in pairs, with an angle between them and a gap. The arrangement of the first plates 15 forms a multi-level flow guiding structure, which decomposes large waves into small eddies, reducing the direct impact on the floating plate. Furthermore, the spacing of the first plates 15 changes the natural frequency of the floating body, avoiding resonance with the common wave frequency (0.1-0.3Hz). The gaps between the first plates 15 also help to collect floating objects that enter the inner side of the first floating body 10, preventing the floating objects from further displacing towards the aquaculture cage 20.

[0056] Example 4:

[0057] This embodiment is a further optimized solution based on embodiment 1, as shown in the appendix. Figure 9 Appendix Figure 11 As shown, a floating element 80 is arranged around the outside of the first float 10, and the distance between the two is between 50m and 100m. The first float 10 and the floating element 80 are connected by a first rope 30.

[0058] The floating component 80 includes a buoyant floating body 81, which is a rotating structure with a through hole in the middle and both ends. The floating body 81 has round holes of different sizes around its perimeter. The first rope 30 can be connected to these round holes. A polygonal or circular float frame 83 is provided on the outside of the floating body 81. The float frame 83 has buoyancy and is connected to the floating body 81 by a buoyancy rod 82.

[0059] The floats 80 surround the aquaculture cages, forming a clear boundary marker to warn passing vessels and prevent accidental collisions that could frighten or harm the tuna inside. They also protect the aquaculture facilities from damage. When objects approach or collide with the cages, the floats 80 act as a buffer, reducing the direct impact on the cages, lowering the risk of breakage, and ensuring a stable living environment for the tuna. The structural arrangement of the float body 81 and the float frame 83 expands the contact surface of the water flow over the floats 80, enhancing wave reduction around them. The number of floats 80 is not limited to... Figure 9 Appendix Figure 11 The quantity shown.

[0060] Example 5:

[0061] This embodiment is a further optimized solution based on embodiment 1, as shown in the appendix. Figure 10 As shown, in this embodiment, the first counterweight 13 can be connected below the first float 10 without the first rope 30. Instead, a fourth counterweight 16 is placed below the float 80, and the two are connected by the first rope 30. Adjacent floats 80 are connected by ropes, and the floating space of the aquaculture cage 20 and the first float 10 on the water surface is controlled within the space constructed between the floats 80. The arrangement of the floats 80 and the first rope 30 can intercept floating objects on the sea surface.

[0062] Example 6:

[0063] This embodiment is a further optimized solution based on embodiment 1, as shown in the appendix. Figure 9 As shown, a gyroscope 70 is mounted on top of the first float 10 via a steel frame structure, with the gyroscope 70 located at the center of the first float 10. The gyroscope 70 is connected to the controller 12 and can monitor the tilting, swaying, and other attitude changes of the aquaculture cage 20 and the first float 10 in real time. Since tuna farming is usually carried out in open waters such as the ocean, it is easily affected by factors such as wind, waves, and currents. When the first float 10 tilts, it will likely also cause the aquaculture cage 20 to tilt. Through the precise measurement of the gyroscope 70, aquaculture personnel can promptly understand the attitude information of the aquaculture cage and determine whether it is in a normal state.
