Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment technology, specifically to an anti-adhesion self-cleaning device for marine aquaculture cages. Background Technology

[0002] The netting of a marine aquaculture cage, as the core structure directly in contact with seawater and cultured organisms within the cage system, mainly consists of the netting, supporting frame, and fixing components. During underwater use, various organisms such as microbial films, shellfish, and algae can form a fouling layer on the outside of the netting. For example, barnacles secrete calcareous shells that firmly adhere to the netting, increasing the cage's weight and reducing its mechanical strength. Therefore, aquaculture cages typically require regular cleaning. However, existing marine aquaculture cages have a large netting structure, requiring multiple pieces of equipment and significant manpower for antifouling treatment, and mechanical cleaning is inherently difficult.

[0003] To address the existing problems in cleaning aquaculture cages, several solutions exist. For example, patent JP2022028911 discloses a cleaning device for aquaculture cages. This device has a conveying section and uses high-pressure water from a self-rotating nozzle to spray onto the aquaculture equipment at a very close distance for cleaning. However, this device does not have the function of cleaning the cages while they are in use; the aquaculture equipment needs to be retrieved before cleaning, making it unsuitable for cleaning large aquaculture cages. Another example is prior art US11433439B2, which discloses a robot driven by a parallel cable for cleaning deep-sea cages and a cleaning system using this robot. Method: The robot includes a terminal cleaning mechanism, a motion controller, and at least two parallel flexible ropes evenly distributed on a net cage. The terminal cleaning mechanism is located inside the net cage. The parallel ropes connect the net cage and the terminal cleaning mechanism. Each parallel rope includes a winding motor fixed to the net cage and a drive cable. The winding motor connects the drive cable to the terminal cleaning mechanism. The motor controller controls the coordinated movement of the at least two parallel flexible ropes to achieve three-dimensional underwater movement of the terminal cleaning mechanism within the net cage. However, there is still room for improvement in achieving energy-free automatic underwater cleaning. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-adhesion self-cleaning device for marine aquaculture cages, which realizes the automatic cleaning of organisms attached to the surface of the netting of marine aquaculture cages. It solves the problems of high cost of manual cleaning, difficulty of mechanical cleaning, and environmental pollution caused by chemical control in the prior art, improves the water exchange efficiency of the cages, reduces aquaculture risks, and reduces aquaculture maintenance costs.

[0005] To address the aforementioned technical problems, this invention provides the following technical solution: an anti-adhesion self-cleaning device for marine aquaculture cages, comprising a rotating aquaculture cage frame. First aquaculture rings are respectively provided at the upper and lower ends of the outer side of the aquaculture cage frame. Annular grooves are formed inside the two first aquaculture rings. Annular slots communicating with the grooves are formed on the opposite surfaces of the two first aquaculture rings. A second connecting rod connects the two first aquaculture rings. A bearing connected to the end of the second connecting rod is provided within the groove. Simultaneously, the structure of the annular grooves and annular slots ensures stable bearing installation, preventing detachment, improving the reliability and self-cleaning efficiency of the device in a marine environment, and reducing aquaculture maintenance costs.

[0006] The aquaculture box frame is a cylindrical structure with at least one metal ring. Adjacent metal rings are connected by rods. Netting is installed on the sides and top and bottom surfaces of the frame to form the aquaculture box. A detachable buckle is provided on the top of the netting to facilitate opening the top for fish fry release, harvesting, and other production operations. This invention uses a rotating frame structure and the first aquaculture rings at the top and bottom to form a stable support frame. The annular groove inside the first aquaculture ring engages with a bearing, allowing the second connecting rod to rotate or slide flexibly, ensuring the cleaning component can move around the frame to clean various areas. The cylindrical metal ring structure of the aquaculture box frame, combined with the netting to form the aquaculture space, and the detachable buckle on the top of the netting facilitate fish fry release and harvesting. When the seawater flows, the second connecting rod, under the action of the bearing, can move with the water flow or the cleaning component, thereby driving the connected roller brush to dynamically clean the netting surface. This eliminates the need for manual cleaning or additional equipment, effectively removing barnacles, algae, and other attached organisms, reducing the weight increase and mechanical strength reduction of the netting.

[0007] According to one embodiment of the present invention, a cleaning assembly capable of moving up and down relative to the second connecting rod is provided on the second connecting rod. The cleaning assembly includes a frame, the frame having two cleaning rods arranged opposite each other with a distance between them, at least two roller brushes connected between the two cleaning rods, the roller brushes being respectively located at both ends of the frame, and a first float being connected to the side of the cleaning rod, the first float having a channel allowing the second connecting rod to pass through.

[0008] The cleaning rod is placed vertically, parallel to the axis of the rotating aquaculture box frame. Two roller brushes are installed at each end of the frame, with a gap between the two roller brushes at one end of the frame.

[0009] The cleaning component mounted on the second connecting rod of this invention can move up and down along it, enabling dynamic cleaning of the aquaculture cage netting. It cleans all areas of the aquaculture cage under the action of water flow without requiring additional energy. The frame of the cleaning component is parallel to the axis of the aquaculture cage via two vertically placed cleaning rods, ensuring that the roller brush can vertically adhere to the netting surface. The roller brushes at both ends of the frame are spaced apart to increase the cleaning coverage area and avoid the problem of reduced cleaning effect due to damage to a single roller brush. The rotating roller brush can peel off barnacles, algae, and other attached substances. The first float, with a channel, is fitted onto the second connecting rod. Its own buoyancy drives the cleaning component to float up and down with the water flow, allowing the roller brush to continuously contact the netting at different depths, achieving full-range cleaning without additional power. This invention combines the buoyancy of the first float with the mechanical friction of the roller brush, not only improving self-cleaning efficiency but also reducing manual maintenance costs. It also solves the problem of traditional cleaning requiring the retrieval of the netting cages, enabling continuous anti-adhesion cleaning operations in seawater environments.

[0010] According to one embodiment of the present invention, two cleaning rods have grooves on their opposite surfaces, and a slider is provided in the groove. A connecting block is connected to one side of the slider, and a second float is provided between the two connecting blocks. The second float is hinged to the connecting blocks via a fourth connecting rod. The second float has a horizontal float body arranged parallel to the roller brush. The slider of the present invention is hinged to the second float via the connecting block, and the horizontal float body of the second float is arranged parallel to the roller brush, thus enabling dynamic buoyancy adjustment. When the seawater flows, the second float, under the action of buoyancy, can drive the connecting block to slide up and down in the groove via the fourth connecting rod, allowing the cleaning assembly to adaptively adjust its height according to water level fluctuations, ensuring that the roller brush always adheres to the surface of the net and cleans the net at different locations. Simultaneously, the hinged structure allows the second float to swing slightly under the impact of water flow, thereby allowing the horizontal float body on the second float to make slight contact with the surface of the roller brush, which helps the material cleaned by the roller brush to detach from the roller brush.

[0011] According to one embodiment of the present invention, a scraper is provided in the chute, and the scraper is connected to the second float via a third connecting rod. The frame has multiple rollers on its side relative to the aquaculture box. The rollers can contact the mesh surface of the aquaculture box. When the cleaning assembly floats up and down with the second connecting rod, the rollers can roll on the mesh surface. On the one hand, the rolling friction assists the roller brush in peeling off the attached materials, enhancing the cleaning effect; on the other hand, it converts the sliding friction between the frame and the mesh into rolling friction, reducing the resistance when the cleaning assembly moves, making the device easier to drive under the action of water flow, reducing energy loss, and preventing the frame from rubbing hard against the mesh, thus avoiding damage to the mesh and improving the stability of the device operation and the service life of the mesh. Furthermore, when the second float swings up and down due to seawater buoyancy or water flow impact, it will drive the scraper to move via the third connecting rod, causing the end of the scraper to contact the brush bristles. At this time, the scraper can scrape off algae, barnacle fragments, and other attached materials that are entangled in the brush during the cleaning process, preventing debris from accumulating on the brush and reducing cleaning efficiency. Meanwhile, the second float, through the hinged structure of the fourth connecting rod and the connecting block, allows the scraper to adaptively adjust its contact angle as the roller brush rotates or the cleaning components float up and down. This ensures that the roller brush can effectively remove the attached debris from the surface of the roller brush under different water flow conditions, maintaining the roller brush in a clean state while adhering to the mesh surface. This improves the overall self-cleaning efficiency of the device and reduces the maintenance cost of manually cleaning the roller brush.

[0012] According to one embodiment of the present invention, a buoyancy control assembly is connected above the first float via a rope. The buoyancy control assembly includes at least two second floats sleeved on a second connecting rod. A connecting cylinder extending vertically between the two second floats is arranged around them. A sleeve connected to the rope of the first float is located below the second floats. A sliding plate is built into the connecting cylinder, and the bottom of the sliding plate is connected to the sleeve via a composite rope. When the seawater flows, the second floats sleeved on the second connecting rod are driven to float by the buoyancy, and the sliding plate can slide up and down in the connecting cylinder with the impact of the water flow. Since the bottom of the sliding plate is connected to the sleeve via the composite rope, and the sleeve is fixed to the rope, when the sliding plate moves upward, it will pull the sleeve upward through the composite rope, thereby raising the height of the first float through the rope. Conversely, the cleaning assembly is driven to move downward along the second connecting rod by its own weight and the downward movement of the buoyancy control assembly caused by the water flow. The solution of the present invention achieves buoyancy adjustment of the first float by the basic buoyancy of the second floats and the dynamic sliding of the sliding plate in the connecting cylinder. When the water level fluctuates or the water flow speed changes, the cleaning component moves up and down with the first float, ensuring that the roller brush always adheres to the surface of the net for cleaning. This avoids blind spots caused by insufficient buoyancy and reduces the hard pulling of the cleaning component by the water flow, improving the adaptability and self-cleaning efficiency of the device in complex sea conditions.

[0013] According to one embodiment of the present invention, a second float plate extends through the connecting cylinder in the vertical direction, and a first float plate is connected above the sliding plate by an adjusting rod. The first float plate is sleeved on the second connecting rod.

[0014] When the seawater flows or the water surface fluctuates, the first float is initially affected by the impact of the water flow or changes in buoyancy. This causes the sliding plate inside the connecting cylinder to slide up and down synchronously via the adjusting rod. At this time, the sliding plate, connected to the column sleeve by the composite rope, converts the displacement of the first float into a pulling or slack force on the column sleeve, thereby controlling the suspension height of the first float via the rope. This invention utilizes the change in the first float with the water surface or flow, transmitting the force to the sliding plate for buoyancy control via the adjusting rod. The second float serves as a lower-level stable support, maintaining the vertical posture of the overall frame through the connecting cylinder. When the first float is pushed upwards by the water flow, the adjusting rod moves the sliding plate upwards, and the composite rope pulls the column sleeve to lift the first float, causing the cleaning assembly to float. When the water flow pushes the first float downwards, the adjusting rod moves the sliding plate downwards, the composite rope slackens, and the cleaning assembly, based on its own weight and the downward movement of the buoyancy control component caused by the water flow, moves downwards along the second connecting rod.

[0015] Specifically, because the frame and roller brush of the cleaning assembly have their own weight, and the downward force of the water flow on the buoyancy control assembly is transmitted downward through the connecting cylinder, the cleaning assembly moves downward along the second connecting rod. This allows the cleaning assembly to move to the area below the aquaculture box frame as the first float moves downward. When the first float is pushed upward by the water flow, it affects the buoyancy of the first float at the bottom, gradually overcoming part of the weight of the cleaning assembly, causing the cleaning assembly to slowly rise. Furthermore, both the first and second floats are fitted onto the second connecting rod, allowing them to slide up and down along the rod. Through the cooperation of the adjusting rod and the connecting cylinder, the horizontal water flow force is converted into a vertical buoyancy control force, preventing the cleaning assembly from shifting due to the lateral impact of the water flow.

[0016] According to one embodiment of the present invention, a sliding plate is provided above the first float plate. Each sliding plate has an opening in its center larger than that of the second connecting rod. At least three extension plates are provided extending outwards from the sides of the sliding plates. Two staggered sliding plates are provided on the second connecting rod. The extension plates on adjacent sliding plates are connected by bent guide vanes. The opening in the center of the sliding plate is larger than that of the second connecting rod, allowing it to slide freely along the second connecting rod. The three extension plates extending outwards from the sides are connected to adjacent sliding plates by bent guide vanes, forming a water flow regulating structure. When seawater flows past the guide vanes, the bent vanes change the direction of the water flow, generating a force that pushes the sliding plates up and down along the second connecting rod. When the sliding plates move upwards, they cause the first float plate to move upwards synchronously, and vice versa.

[0017] According to one embodiment of the present invention, both the first float and the second float have openings in their middle portions that are larger than the second connecting rod. Because the diameter of the openings is larger than the outer diameter of the second connecting rod, the two floats can slide freely up and down along the rod. When seawater flows or the water level fluctuates, the first float and the second float can slide under the influence of water flow impact and buoyancy, respectively. Through the linkage between the adjusting rod and the connecting cylinder, the vertical displacement of the floats is converted into buoyancy control of the cleaning assembly.

[0018] According to one embodiment of the present invention, two first breeding rings are connected and fixed to the outer wall of the breeding box frame via a first connecting rod arranged around the ring. The connection method can be welding, or a detachable connecting sleeve can be used to connect and fix the first connecting rod with fasteners, and then the detachable connecting sleeve is connected to the breeding box frame. This connection method allows the spacing and height position of the two first breeding rings on the breeding box frame to be adjusted as needed.

[0019] According to one embodiment of the present invention, the width of the slide groove is smaller than the width of the annular slot. This prevents the bearing inside the slide groove from dislodging from the slide groove.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: The solution of the present invention solves the problems of high labor costs, difficult mechanical cleaning, and chemical pollution in the prior art, realizes energy-free automatic cleaning, improves water exchange efficiency and reduces aquaculture maintenance costs.

[0024] 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.

[0025] 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. Example 1

[0026] As shown in the attached figure Figure 1 - Appendix Figure 8 As shown, the anti-adhesion self-cleaning device for marine aquaculture cages includes a rotating aquaculture cage frame 10. The upper and lower ends of the outer side of the aquaculture cage frame 10 are respectively provided with first aquaculture rings 12. Annular grooves 14 are formed inside the two first aquaculture rings 12. Annular slots communicating with the grooves 14 are formed on the opposite surfaces of the two first aquaculture rings 12. A second connecting rod 13 connects the two first aquaculture rings 12. A bearing connected to the end of the second connecting rod 13 is provided inside the grooves 14. The structure of the annular grooves 14 and the annular slots ensures that the bearings are securely installed, preventing them from falling off, improving the reliability and self-cleaning efficiency of the device in the marine environment, and reducing aquaculture maintenance costs.

[0027] The aquaculture box frame 10 has a cylindrical structure with at least three metal rings. Adjacent metal rings are connected by rods. A net is installed on the sides and top and bottom surfaces of the aquaculture box frame 10 to form the aquaculture box. A detachable buckle is provided on the top of the net to facilitate opening the top of the aquaculture box for fish fry release, harvesting, and other production operations. This invention uses the rotating structure of the aquaculture box frame 10 and the first aquaculture rings 12 at the top and bottom to form a stable support frame. The annular groove 14 inside the first aquaculture ring 12 cooperates with a bearing, allowing the second connecting rod 13 to rotate or slide flexibly, ensuring that the cleaning component 40 can move around the aquaculture box frame 10 to clean its various positions. The aquaculture box frame 10 uses a cylindrical metal ring structure, combined with a net to form an aquaculture space. The detachable buckle on the top of the net facilitates fish fry release and harvesting operations. When the seawater flows, the second connecting rod 13 can move with the water flow or the cleaning component 40 under the action of the bearing, thereby driving the connected roller brush 42 to dynamically clean the surface of the net. No manual retrieval or additional equipment is required, which effectively removes barnacles, algae and other attached substances, and reduces the problems of increased net cage weight and decreased mechanical strength.

[0028] The second connecting rod 13 is provided with a cleaning assembly 40 that can move up and down relative to it. The cleaning assembly 40 includes a frame 41. The frame 41 has two cleaning rods that are arranged opposite each other and spaced apart. At least two roller brushes 42 are connected between the two cleaning rods. The roller brushes 42 are respectively located at both ends of the frame 41. A first float 43 is connected to the side of the cleaning rod. The first float 43 has a channel that allows the second connecting rod 13 to pass through.

[0029] The cleaning rod is placed vertically, parallel to the axis of the rotating breeding box frame 10. Two roller brushes 42 are installed at each end of the frame 41, with a gap between the two roller brushes 42 at one end of the frame 41.

[0030] The cleaning component 40 mounted on the second connecting rod 13 of this invention can move up and down along it, thus enabling dynamic cleaning of the netting of the aquaculture box 10. It cleans all parts of the aquaculture box 10 under the action of water flow without requiring additional energy. The frame 41 of the cleaning component 40 is parallel to the axis of the aquaculture box 10 via two vertically placed cleaning rods, ensuring that the roller brush 42 can vertically adhere to the surface of the netting. The roller brushes 42 at both ends of the frame 41 are spaced apart to increase the cleaning coverage area and avoid the problem of reduced cleaning effect due to damage to a single roller brush 42. When the roller brush 42 rotates, it can peel off barnacles, algae, and other attached substances. The first float 43 has a channel and is fitted onto the second connecting rod 13. Using its own buoyancy, it drives the cleaning component 40 to float up and down with the water flow, allowing the roller brush 42 to continuously contact the netting at different depths, achieving full-range cleaning without additional power. This invention combines the buoyancy of the first float 43 with the mechanical friction of the roller brush 42, which not only improves the self-cleaning efficiency but also reduces the cost of manual maintenance. At the same time, it solves the problem of traditional cleaning requiring the retrieval of net cages, enabling continuous anti-adhesion cleaning operations in seawater environments.

[0031] Two cleaning rods have grooves on their opposite sides, and sliders are installed in the grooves. A connecting block 46 is connected to one side of the slider, and a second float 44 is provided between the two connecting blocks 46. The second float 44 is hinged to the connecting blocks 46 via a fourth connecting rod 49. The second float 44 has a horizontal float body arranged parallel to the roller brush 42. In this invention, the slider is hinged to the second float 44 via the connecting block 46, and the horizontal float body of the second float 44 is arranged parallel to the roller brush 42, which allows for dynamic buoyancy adjustment. When the seawater flows, the second float 44, under the action of buoyancy, can drive the connecting block 46 to slide up and down in the groove via the fourth connecting rod 49, so that the cleaning assembly 40 can adaptively adjust its height according to the water level fluctuation, ensuring that the roller brush 42 always adheres to the surface of the net and cleans the net at different positions. At the same time, the hinged structure allows the second float 44 to swing slightly under the impact of the water flow, thereby allowing the horizontal float body on the second float 44 to make slight contact with the surface of the roller brush 42, which helps the material cleaned by the roller brush 42 to detach from the roller brush 42.

[0032] A scraper 47 is installed inside the chute, and the scraper 47 is connected to the second float 44 via a third connecting rod 48. The frame 41 has four rollers 45 on its side relative to the aquaculture box frame 10, symmetrically arranged. The rollers 45 can contact the mesh surface of the aquaculture box frame 10. When the cleaning component 40 floats up and down with the second connecting rod 13, the rollers 45 can roll on the mesh surface. On the one hand, the rolling friction assists the roller brush 42 in peeling off the attached substances, enhancing the cleaning effect; on the other hand, it converts the sliding friction between the frame 41 and the mesh into rolling friction, reducing the resistance when the cleaning component moves, making the device easier to drive under the action of water flow, reducing energy loss, and preventing the frame 41 from rubbing hard against the mesh, thus avoiding damage to the mesh and improving the stability of the device operation and the service life of the mesh. Furthermore, when the second float 44 swings up and down due to seawater buoyancy or water flow impact, it will drive the scraper 47 to move via the third connecting rod 48, so that the end of the scraper 47 contacts the bristle surface of the roller brush 42. At this time, the scraper 47 can scrape off algae, barnacle fragments, and other attached substances that are entangled in the roller brush 42 during the cleaning process of the mesh, preventing debris from accumulating on the roller brush 42 and causing a decrease in cleaning efficiency. At the same time, the second float 44, through the hinged structure of the fourth connecting rod 49 and the connecting block 46, allows the scraper 47 to adaptively adjust its contact angle as the roller brush 42 rotates or the cleaning assembly 40 floats up and down, ensuring that it can effectively peel off the attached debris from the surface of the roller brush 42 under different water flow conditions, maintaining the roller brush 42 in a clean state while adhering to the mesh surface, thereby improving the overall self-cleaning efficiency of the device and reducing the maintenance cost of manually cleaning the roller brush.

[0033] A buoyancy control assembly 30 is connected above the first float 43 via a rope 50. The buoyancy control assembly 30 includes at least two second float plates 35 sleeved on the second connecting rod 13. A vertically extending connecting cylinder 36 is arranged around the two second float plates 35. Below the second float plates 35 is a column sleeve 37 connected to the rope 50 of the first float 43. A sliding plate 39 is built into the connecting cylinder 36, and the bottom of the sliding plate 39 is connected to the column sleeve 37 via a composite rope 38. When the seawater flows, the second float plates 35 sleeved on the second connecting rod 13 are driven by buoyancy, causing the connecting cylinder 36 to float. At this time, the sliding plate 39 can slide up and down with the impact of the water flow within the connecting cylinder 36. Since the bottom of the sliding plate 39 is connected to the column sleeve 37 via the composite rope 38, and the column sleeve 37 is fixed to the rope body 50, when the sliding plate 39 moves upward, it will pull the column sleeve 37 upward via the composite rope 38, thereby raising the height of the first float 43 via the rope body 50; conversely, the cleaning component 40 moves downward along the second connecting rod 13 based on its own weight and the downward movement of the buoyancy control component 30 caused by the water flow. The solution of the present invention achieves buoyancy adjustment of the first float 43 by using the basic buoyancy of the second float plate 35 and the dynamic sliding of the sliding plate 39 within the connecting cylinder 36. When the water level fluctuates or the water flow speed changes, the cleaning component 40 floats up and down with the first float 43, ensuring that the roller brush 42 always adheres to the surface of the net for cleaning, avoiding blind spots due to insufficient buoyancy, and reducing the hard pulling of the cleaning component 40 by the water flow impact, thus improving the adaptability and self-cleaning efficiency of the device in complex sea conditions.

[0034] The first float 33 is located above the second float 35. The connecting cylinder 36 passes through the second float 35 in its vertical direction. The first float 33 is connected above the sliding plate 39 via an adjusting rod 34, and the first float 33 is fitted onto the second connecting rod 13. When the seawater flows or the water surface fluctuates, the first float 33 is first affected by the impact of the water flow or changes in buoyancy, and the adjusting rod 34 drives the sliding plate 39 inside the connecting cylinder 36 to slide up and down synchronously. At this time, the sliding plate 39, through the connection between the composite rope 38 and the column sleeve 37, converts the displacement of the first float 33 into a pulling or slack force on the column sleeve 37, and then adjusts the suspension height of the first float 43 through the rope 50. This invention utilizes the change of the first float 33 with the water surface or water flow, and transmits the force to the sliding plate 39 through the adjusting rod 34 for buoyancy control, while the second float 35 serves as a lower stable support, maintaining the vertical posture of the overall frame through the connecting cylinder 36. When the first float 33 is pushed upward by the water flow, the adjusting rod 34 drives the sliding plate 39 to move upward, and the composite rope 38 pulls the column sleeve 37 to lift the first float 43, causing the cleaning assembly 40 to float upward; when the water flow pushes the first float 33 downward, the adjusting rod 34 drives the sliding plate 39 to move downward, the composite rope 38 slackens, and the cleaning assembly 40 moves downward along the second connecting rod 13 based on its own weight and the downward movement of the buoyancy control assembly 30 caused by the water flow.

[0035] Specifically, since the frame 41 and roller brush 42 of the cleaning assembly 40 have their own weight, and the downward pushing force of the water flow on the buoyancy control assembly 30 is transmitted downward through the connecting cylinder 36, the cleaning assembly 40 will move downward along the second connecting rod 13. This allows the cleaning assembly 40 to move to the area below the breeding box frame 10 as the first float 33 moves downward. When the first float 33 is pushed upward by the water flow, it affects the buoyancy of the first float block 43 at the bottom, gradually overcoming part of the weight of the cleaning assembly 40, causing the cleaning assembly 40 to slowly float upward. Furthermore, both the first float 33 and the second float 35 are fitted onto the second connecting rod 13, allowing them to slide up and down along the rod. Through the cooperation of the adjusting rod 34 and the connecting cylinder 36, the horizontal water flow force is converted into a vertical buoyancy control force, preventing the cleaning assembly 40 from shifting due to the lateral impact of the water flow.

[0036] A sliding plate 31 is provided above the first float 33. Each sliding plate 31 has an opening in its center larger than that of the second connecting rod 13. At least three extension plates are provided on the outer side of the sliding plate 31. Two sliding plates 31 are provided on the second connecting rod 13 in a staggered manner. The extension plates on adjacent sliding plates 31 are connected by bent guide vanes 32. The opening in the center of the sliding plate 31 is larger than that of the second connecting rod 13, allowing it to slide freely along the second connecting rod 13. The three extension plates on the outer side are connected to adjacent sliding plates 31 by bent guide vanes 32, forming a water flow regulating structure. When seawater flows through the guide vanes 32, the bent vanes change the direction of the water flow, generating a force that pushes the sliding plate 31 to move up and down along the second connecting rod 13. When the sliding plate 31 moves upward, it drives the first float 33 to move upward synchronously, and vice versa.

[0037] Both the first float plate 33 and the second float plate 35 have openings in the middle that are larger than those of the second connecting rod 13. Because the diameter of the openings is larger than the outer diameter of the second connecting rod 13, the two float plates can slide freely up and down along the rod. When the seawater flows or the water level fluctuates, the first float plate 33 and the second float plate 35 can slide under the action of water flow impact force and buoyancy respectively. Through the linkage between the adjusting rod 34 and the connecting cylinder 36, the vertical displacement of the float plates is converted into buoyancy control of the cleaning component 40.

[0038] The two first breeding rings 12 are connected and fixed to the outer wall of the breeding box frame 10 via the first connecting rod 11 that is arranged around them. The connection method can be welding, or a detachable connecting sleeve can be used to connect and fix the first connecting rod 11 with fasteners, and then the detachable connecting sleeve can be connected to the breeding box frame 10. This connection method allows the spacing and height position of the two first breeding rings 12 on the breeding box frame 10 to be adjusted as needed.

[0039] The width of the groove 14 is smaller than the width of the annular slot. This prevents the bearing inside the groove 14 from dislodging. The annular slot has a pre-set installation opening that allows the bearing to enter and exit. This opening is used to install the bearings at the upper and lower ends of the second connecting rod 13 during installation. After installation, the installation opening is sealed by welding to form a complete annular slot. If there are welding burrs or changes in the spacing of the annular slot in the welded part, corresponding treatments should be taken, such as grinding. Example 2

[0040] This embodiment provides a further solution based on Embodiment 1, see Appendix. Figure 1 Appendix Figure 9 As shown.

[0041] A buffer component 20 is fitted onto the second connecting rod 13. The buffer component 20 includes a buffer plate 21 fitted onto the second connecting rod 13. The buffer plate 21 has a hollow cavity inside and a communication port on its side that communicates with the cavity. The buffer plate 21 is a rotating structure, specifically a disc-shaped structure. An outer ring is provided on the outside of the buffer plate 21, which is coaxial with its axis. The outer ring is connected to the outer wall of the buffer plate 21 by a blade 22. The blade 22 is a polygonal plate structure, with its two sides connected to the inner wall of the outer ring and the outer wall of the buffer plate 21, respectively. The blade 22 is inclined, that is, the surface of the blade 22 and the axis of the buffer plate 21 form an angle under projection. There are multiple blades 22, which fill the space between the buffer plate 21 and the outer ring. The entire component of the buffer component 20 is made of rubber. The buffer 20 located below the second connecting rod 13 has no buoyancy, while the buffer 20 located above the second connecting rod 13 has buoyancy. When seawater flows through the buffer 20, the inclined blades 22 can decompose the impact force of the water flow, which helps to promote the movement of the second connecting rod 13 and uses the decomposed water flow to clean debris inside the chute 14 where the second connecting rod 13 is located. Specifically, the blades 22 guide part of the water flow to the chute 14. In this way, when the second connecting rod 13 moves in the chute 14, the water guided by the blades 22 flushes the inside of the chute 14, which helps to discharge the objects inside the chute 14 and prevents the second connecting rod 13 from getting stuck. When the second connecting rod 13 rotates or the cleaning assembly 40 floats up and down, the presence of the buffer 20 can prevent the cleaning assembly 40 or the buoyancy control assembly 30 from impacting the first aquaculture ring 12 in the vertical direction. Example 3

[0042] In this example, this embodiment further optimizes the chute 14 scheme based on the scheme of embodiment 1. Several balls or springs are placed in the sliding channel of the chute 14, which are used to push and sweep out any organisms or sediments that may exist in the chute 14 by using thrust to displace the balls or springs during the movement of the second connecting rod 13 relative to the chute 14.
