Description

Technical Field

[0001] This invention relates to the field of aquaculture equipment technology, specifically a raft-type three-dimensional aquaculture device that integrates monitoring and automatic cleaning. Background Technology

[0002] In the aquaculture industry, raft-type three-dimensional aquaculture devices are commonly used for marine aquaculture of shellfish, algae, and shrimp. These devices typically use an aquaculture frame as the basic support structure, combined with aquaculture net cages to achieve three-dimensional aquaculture. This allows for full utilization of water space and meets the actual needs of large-scale marine aquaculture. However, existing raft-type three-dimensional aquaculture devices generally only have a basic aquaculture frame and net cage connection structure, which can only meet the basic placement requirements for aquaculture. In actual aquaculture operations, the aquaculture net cages are constantly exposed to seawater, and their side walls are prone to the accumulation of sea mud and algae. At the same time, the growth of the cultured organisms will cause changes in the overall weight of the aquaculture net cages, requiring regular cleaning and adjustment of the net cages' buoyancy to ensure they are at a suitable water depth. In current aquaculture operations, the status monitoring, cleaning, and buoyancy adjustment of the aquaculture net cages are all done manually. The device itself lacks an integrated intelligent control structure and linkage execution mechanism, with each functional link operating independently and lacking a design concept for collaborative operation.

[0003] Existing raft-type aquaculture systems lack an integrated design that combines intelligent monitoring, automatic cleaning, and buoyancy adjustment. The systems themselves lack a dedicated monitoring structure for real-time detection of the weight of the aquaculture cages, making it impossible to accurately and promptly assess weight changes caused by accumulated deposits or the growth of the aquaculture organisms. Furthermore, the cleaning and buoyancy adjustment structures lack coordinated control logic, relying entirely on manual brushing for cleaning. Buoyancy adjustments are also mostly fixed settings, failing to adapt to the actual weight of the cages. This results in extremely low automation and poor overall efficiency. Manual brushing can also cause mechanical damage to the cages, disturbing or even injuring the aquaculture organisms inside, and makes it difficult to ensure uniform and timely cleaning. Therefore, these systems are ill-suited to the actual production needs of large-scale raft-type aquaculture. Thus, there is an urgent need to develop a raft-type aquaculture system that integrates monitoring and automatic cleaning to overcome the shortcomings of current applications. Summary of the Invention

[0004] The purpose of this invention is to provide a raft-type three-dimensional aquaculture device that integrates monitoring and automatic cleaning to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0016] And a second rotating cleaning cylinder, there are multiple second rotating cleaning cylinders, all of which are rotatably connected to the breeding frame and are set perpendicular to the first rotating cleaning cylinder, and the second rotating cleaning cylinder is also connected to an external drive device;

[0017] The external intelligent control system controls the start of the external drive equipment, which in turn drives the multiple rotating cleaning cylinders one and two to rotate.

[0018] As a further embodiment of the present invention: the rotating cleaning cylinder and the air hole directly form multiple cleaning squares, and the multiple suspended aquaculture cages are respectively placed in the multiple cleaning squares;

[0019] Both the rotating cleaning cylinder and the air vent are equipped with brushes. The brushes contact the side wall of the suspended aquaculture cage and perform a rotary cleaning of the side wall of the suspended aquaculture cage as it floats upward.

[0020] As a further aspect of the present invention: the rotating cleaning cylinder and the air hole are respectively provided with air hole one and air hole two, and are connected to an external air source through an adapter.

[0021] As a further aspect of the present invention, it also includes: a cage cover, which is detachably mounted on the square frame base plate and is used to enclose the top of the suspended aquaculture cage.

[0022] The cage cover is fixedly installed with a positioning flange, which is snap-fitted to the square frame base plate.

[0023] As a further aspect of the present invention: the buoyancy alternation component includes an airbag plane, a delivery air pipe, an inflation port, and a suction port;

[0024] The airbag plane abuts against the bottom wall of the suspended aquaculture cage, and both ends of the airbag plane are provided with air delivery pipes. The ends of the air delivery pipes are provided with an inflation port and a suction port, which are connected to an external air source.

[0025] The airbag plane includes an adjustable floating airbag, a first winding support belt, a side cleaning opening, a second winding support belt, and a third winding support belt.

[0026] The winding support belt 1, winding support belt 2 and winding support belt 3 are separated by a side cleaning opening, and the number of adjustable floating airbags provided on the winding support belt 3, winding support belt 1 and winding support belt 2 increases sequentially.

[0027] In the normal working state of the suspended aquaculture cage, the two side walls of the suspended aquaculture cage are directly opposite the two side cleaning openings, and the three winding support straps are placed at the bottom wall of the suspended aquaculture cage.

[0028] And an airbag transformation drive unit, which is located on the square base plate and connected to the airbag plane.

[0029] As a further aspect of the present invention: the number of airbag transformation driving units is two sets, and the two sets of airbag planes are respectively connected to both ends of the airbag plane;

[0030] The airbag plane includes a winding drive device, a winding shaft, and a scraping port;

It can automatically trigger cleaning and buoyancy adjustment actions according to the real-time weight status of the aquaculture cage, which greatly improves the automation and intelligence level of raft-type three-dimensional aquaculture operations.

[0037] The roller brush cleaning structure uses a combination of vertically set rotating cleaning cylinder and bubble impact cleaning method. The soft brush and the micro-impact force of bubble bursting can effectively remove sea mud and algae and other attached substances from the side wall of the cage, while avoiding mechanical damage to the aquaculture cage.

[0038] The air hole design of the roller brush cleaning structure enables the brush to self-clean, promptly removing dirt attached to the brush, preventing the growth of bacteria from the dirt, and maintaining the hygiene of the breeding environment while ensuring the cleaning effect.

[0039] The buoyancy alternation component enables precise adjustment of the buoyancy of the aquaculture cage in stages. It can adaptively switch the buoyancy level according to the weight change of the cage, ensuring that the aquaculture cage is always at a suitable water depth, creating a good growth environment for the aquaculture species.

[0040] During the buoyancy adjustment process, the self-cleaning of the aquaculture cage and airbag plane can be completed simultaneously, realizing the coordinated operation of buoyancy adjustment and cleaning, without the need for additional manual operation, and further improving the efficiency of aquaculture operations;

[0041] The limit detector, combined with the guide slide rod, can detect the overall weight status of the aquaculture cage in real time and accurately. The sliding fit between the guide slide rod and the guide hole can adapt to the vertical displacement of the cage when the buoyancy changes, thus ensuring the monitoring accuracy at all times.

[0042] The device adopts a detachable square frame base plate, cage cover and other structural designs, which facilitates cage management, cage replacement and maintenance and non-destructive sampling and testing of the farmed objects during the breeding process, and is suitable for the daily operation needs of large-scale breeding.

Detailed Implementation

[0060] 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.

[0061] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0062] Please see Figures 1-14 The present invention provides a raft-type three-dimensional aquaculture device integrating monitoring and automatic cleaning, including an aquaculture frame 1, on which multiple square frame base plates 4 are detachably installed, and each square frame base plate 4 is provided with a hanging aquaculture net cage 2.

[0063] The aquaculture frame 1 is also equipped with a roller brush cleaning structure, which is used to clean the side walls of each of the suspended aquaculture cages 2.

[0064] And a buoyancy alternation component, which is connected to the suspended aquaculture cage 2 and the square frame base plate 4 respectively, for adjusting the buoyancy of the entire suspended aquaculture cage 2 and performing self-cleaning at the same time;

[0065] Both the roller brush cleaning structure and the buoyancy alternation component are connected to an external intelligent control system to control the operation of the roller brush cleaning structure and the buoyancy alternation component according to the weight status of the suspended aquaculture cage 2, so as to clean the suspended aquaculture cage 2.

[0066] In the field of raft-type aquaculture, existing technologies for raft-type devices for aquaculture such as shellfish, algae and shrimp generally lack the linkage design of intelligent monitoring and automatic cleaning. Cleaning operations mostly rely on manual scrubbing, which is not only inefficient but also prone to causing mechanical damage to the aquaculture objects.

[0067] In this invention, the aquaculture frame 1 uses 304 stainless steel, which is resistant to seawater corrosion, as the overall load-bearing foundation. The food-grade plastic square frame base 4 is detachably installed on the aquaculture frame 1 and can be adapted to nylon hanging aquaculture net cages 2 with different mesh sizes to meet the aquaculture needs of different aquaculture species. The external intelligent control system uses a mature PLC programmable logic controller as its core, combined with a weight sensing module, an action execution module, and a wireless signal transmission module. It can realize real-time acquisition of physical signals, data analysis, and linkage control of the actuators. The intelligent control system first presets the weight threshold parameters for hanging aquaculture net cages 2 according to the aquaculture species. By acquiring the weight status of the net cages in real time, it judges whether there is an abnormal weight due to the attachment of sea mud and algae or the growth of the aquaculture species. When the weight change exceeds the preset threshold, the system will immediately clean the roller brush. The alternating structure and buoyancy components send a linkage action electrical signal, and the roller brush cleaning structure then starts to automatically clean the side wall of the suspended aquaculture cage 2. At the same time, the alternating buoyancy components synchronously adjust the buoyancy of the suspended aquaculture cage 2, and complete the self-cleaning action of the aquaculture cage (one or more designated suspended aquaculture cages 2 are cleaned) during the buoyancy adjustment process. The two work together to replace the traditional manual cleaning and buoyancy adjustment methods, which not only greatly improves the automation level of the aquaculture device, but also minimizes the interference with the cultured objects in the suspended aquaculture cage 2 during the cleaning process, ensuring the stability of the aquaculture water environment. At the same time, the way the detachable square frame base plate 4 is connected with the suspended aquaculture cage 2 also facilitates cage management, cage replacement and maintenance, and sampling and testing of cultured objects during the aquaculture process, perfectly adapting to the actual production needs of large-scale raft-type three-dimensional aquaculture.

[0068] In one embodiment of the present invention, please refer to Figures 1-14 It also includes: a fixed-distance support 19, which is fixedly connected to the square frame base plate 4, and a guide slide rod 5 is fixedly installed on the fixed-distance support 19;

[0069] The guide slide rod 5 forms a clean space with the side wall of the suspended aquaculture cage 2 through the fixed-distance support 19;

[0070] And guide hole 7, which is opened on the breeding frame 1, and the other end of guide slide rod 5 is inserted into guide hole 7 and slidably connected with guide hole 7.

[0071] It also includes a limit detector 6, which is detachably installed on the guide slide rod 5 and connected to an external intelligent control system for real-time detection of the overall weight of the suspended aquaculture cage 2.

[0072] In this invention, the fixed-distance support 19 is made of corrosion-resistant fiberglass and welded to the square frame base plate 4, providing a stable and rigid support foundation for the guide slide rod 5. The guide slide rod 5 is made of seawater-resistant 316 stainless steel, with one end welded to the fixed-distance support 19 and the other end inserted into the guide hole 7 on the aquaculture frame 1 to form a sliding fit. Through the standardized spacing design of the fixed-distance support 19, a standardized cleaning space adapted to the operation of the roller brush cleaning structure is formed between the guide slide rod 5 and the side wall of the suspended aquaculture cage 2, effectively avoiding mechanical damage to the suspended aquaculture cage 2 caused by excessive contact between the cleaning structure and the side wall of the suspended aquaculture cage 2. At the same time, a limit detector 6 (i.e., a weight sensing module) is detachably installed on the guide slide rod 5 by a stainless steel clamp. The limit detector 6 uses a mature laser displacement weight sensor, which is connected to the external PLC intelligent control system via a 485 wireless signal. The sensor 6 detects the change in the distance between the guide slide rod 5 and the aquaculture frame 1 in real time, combined with... The system presets parameters such as the material of the suspended aquaculture cage 2, the density of the aquaculture medium, and the specifications of the suspended aquaculture cage 2. It calculates and accurately detects the overall weight of the suspended aquaculture cage 2 in real time and transmits the weight electrical signal to the intelligent control system in real time. When the detected weight value exceeds the preset threshold of the system, the control system will immediately trigger the subsequent cleaning and buoyancy adjustment action commands. The sliding fit structure of the guide rod 5 and the guide hole 7 can also adapt to the vertical displacement of the suspended aquaculture cage 2 when the buoyancy changes, and always ensure the monitoring accuracy of the limit detector 6. At the same time, the fixed distance design of the fixed distance support 19 also ensures that the multiple suspended aquaculture cages 2 maintain a uniform distance, which not only ensures the growth space of the aquaculture objects, but also provides a structural basis for the standardized and batch operation of the cleaning structure. It effectively solves the technical problems of easy corrosion of the limit structure of traditional aquaculture devices, outdated monitoring methods, and inability to monitor in real time. It also provides a standardized position basis for the suspended aquaculture cage 2 for sampling operations in the aquaculture process, which facilitates the precise operation of sampling tools.

[0073] In one embodiment of the present invention, please refer to Figures 1-14 The roller brush cleaning structure includes:

[0074] There are multiple rotating cleaning cylinders 8, each of which is rotatably connected to the breeding frame 1 and connected to an external drive device.

[0075] And a second rotating cleaning cylinder 10, there are multiple second rotating cleaning cylinders 10, all of which are rotatably connected to the breeding frame 1 and are set perpendicular to the first rotating cleaning cylinder 8, and the second rotating cleaning cylinder 10 is also connected to an external drive device.

[0076] The external intelligent control system controls the start of the external drive equipment, which in turn drives the multiple rotating cleaning cylinders 8 and 10 to rotate.

[0077] The rotating cleaning cylinder 8 and the air hole 9 directly form multiple cleaning squares, and the multiple suspended aquaculture cages 2 are respectively placed in the multiple cleaning squares;

[0078] Both the rotating cleaning cylinder 8 and the air hole 9 are equipped with brushes. The brushes contact the side wall of the suspended aquaculture cage 2 and perform rotary cleaning on the side wall of the suspended aquaculture cage 2 during the upward floating process.

[0079] Please see Figure 3 and Figure 4 The rotating cleaning cylinder 8 and the air hole 9 are respectively provided with air hole 9 and air hole 11, and are connected to an external air source through an adapter.

[0080] When the rotating cleaning cylinder 8 and the air hole 9 are used for rotating cleaning, the gas from the external air source is ejected through the multiple small air holes (which are connected to the air hole 9 and the air hole 11) set on the brush of the rotating cleaning cylinder 8 and the air hole 9, so as to form impact bubbles during the cleaning process, thereby further increasing the cleaning effect and preventing the brush from getting dirty (it has the function of cleaning the brush).

[0081] In this invention, both the rotating cleaning cylinder 1 (8) and rotating cleaning cylinder 2 (10) of the roller brush cleaning structure are made of high-strength, seawater-resistant engineering plastic (which can be positioned above the water surface). Multiple rotating cleaning cylinders 1 (8) are rotatably connected to the aquaculture frame 1 via waterproof bearings. Similarly, multiple rotating cleaning cylinders 2 (10) are rotatably connected to the aquaculture frame 1 via waterproof bearings and are spatially perpendicular to the rotating cleaning cylinders 1 (8). Both are connected to a mature waterproof geared motor as an external drive device (the geared motor can be connected to the rotating cleaning cylinder via a gear set). Upon receiving a weight exceedance signal from the limit detector 6, the external PLC intelligent control system immediately controls the waterproof geared motor to start, driving multiple rotating cylinders... The first cleaning cylinder 8 and the second rotating cleaning cylinder 10 rotate synchronously and at a uniform speed. The first rotating cleaning cylinder 8 and the second rotating cleaning cylinder 10 cooperate to form multiple cleaning squares of uniform size. Multiple suspended aquaculture cages 2 are placed in the corresponding cleaning squares. The outer walls of the first rotating cleaning cylinder 8 and the second rotating cleaning cylinder 10 are fixed with soft nylon brushes. The brushes are in flexible contact with the side walls of the suspended aquaculture cages 2. As the suspended aquaculture cages 2 float upward with the buoyancy alternating components, the vertically set first rotating cleaning cylinder 8 and the second rotating cleaning cylinder 10 drive the brushes to perform all-round swirl cleaning of the four side walls of the suspended aquaculture cages 2, effectively removing aquaculture attachments such as sea mud and algae attached to the side walls of the suspended aquaculture cages 2.

[0082] Simultaneously, air vent 9 is provided on the rotating cleaning cylinder 18, and air vent 11 is provided on the rotating cleaning cylinder 20. Both are connected to a corrosion-resistant high-pressure air pump suitable for marine aquaculture in existing technology via stainless steel waterproof adapters as an external air source. While the rotating cleaning cylinders 18 and 20 are rotating and cleaning, the high-pressure gas output from the external high-pressure air pump enters air vent 9 and air vent 11 through the adapters, and is then ejected at high speed through multiple micron-sized air vents connected to air vent 9 and air vent 11 at the brush. This forms dense impact bubbles on the side wall of the suspended aquaculture cage 2. The micro-impact force generated when the bubbles burst can further peel off stubborn deposits on the side wall of the suspended aquaculture cage 2. This method significantly improves cleaning effectiveness. Simultaneously, the high-speed air jets can reverse-blow the brushes, promptly removing dirt and preventing bacterial growth. This self-cleaning mechanism effectively solves the technical problems of poor cleaning performance and easily soiled brushes associated with traditional cleaning methods. Furthermore, the combination of flexible brushes and air jets prevents mechanical damage to the suspended aquaculture cages 2 and minimizes disturbance to the aquaculture organisms inside. After cleaning, the mesh of the suspended aquaculture cages 2 remains permeable, facilitating water exchange and creating a favorable growth environment for the aquaculture organisms. It also provides a clean foundation for subsequent sampling and testing, preventing interference from attached substances with the sampling results.

[0083] In one embodiment of the present invention, please refer to Figures 1-7It also includes: a cage cover 3, which is detachably installed on the square frame base plate 4 and is used to enclose the top of the suspended aquaculture cage 2;

[0084] The cage cover 3 is fixedly installed with a positioning flange 17, which is snap-fitted to the square frame base plate 4.

[0085] In this invention, the cage cover 3 is made of lightweight, high-strength fiberglass. It is connected to the square frame base plate 4 via a positioning flange 17. The positioning flange 17 is an annular flange made of elastic, seawater-resistant rubber, integrally formed with the cage cover 3. Its outer diameter matches the inner diameter of the mounting groove on the square frame base plate 4. During installation, the cage cover 3 is fastened to the top of the suspended aquaculture cage 2, causing the positioning flange 17 to engage with the mounting groove on the square frame base plate 4. The deformation characteristics of the elastic rubber achieve a tight connection between the cage cover 3 and the square frame base plate 4, completing the sealing of the top of the suspended aquaculture cage 2. This snap-fit ​​connection method replaces the traditional rope binding, making operation simple and the connection... The structure is sturdy and can effectively resist the impact of seawater currents and waves, preventing the escape of farmed organisms and the invasion of predatory organisms, and ensuring the closed nature of the farming environment. At the same time, the detachable cage cover 3 structure also facilitates the feeding of the suspended farming net cage 2, cleaning of the inside of the suspended farming net cage 2, and sampling and testing of farmed organisms during the farming process. When sampling, the cage cover 3 only needs to be removed from the square frame base plate 4 to achieve non-destructive sampling of farmed organisms inside the suspended farming net cage 2. It is suitable for the daily operation and sampling and testing needs of raft-type three-dimensional aquaculture. Moreover, the lightweight fiberglass cage cover 3 does not increase the overall load of the farming frame 1, ensuring the structural stability of the farming device.

[0086] In one embodiment of the present invention, please refer to Figures 1-14 The buoyancy alternation assembly includes an airbag plane, an air delivery pipe 24, an inflation port 25, and a suction port 26;

[0087] The airbag plane abuts against the bottom wall of the suspended aquaculture cage 2, and both ends of the airbag plane are provided with air delivery pipes 24. The ends of the air delivery pipes 24 are provided with an inflation port 25 and a suction port 26, and the inflation port 25 and the suction port 26 are connected to an external air source.

[0088] The airbag plane includes an adjustable floating airbag 14, a first winding support belt 15, a side cleaning opening 16, a second winding support belt 22, and a third winding support belt 23.

[0089] The winding support belt 15, winding support belt 22 and winding support belt 3 23 are separated by a side cleaning opening 16, and the number of adjustable floating airbags 14 provided on the winding support belt 3 23, winding support belt 15 and winding support belt 22 increases sequentially.

[0090] In the normal working state of the suspended aquaculture cage 2, the two side walls of the suspended aquaculture cage 2 are directly opposite the two side cleaning openings 16, and the winding support belt 23 is placed at the bottom wall of the suspended aquaculture cage 2.

[0091] And an airbag transformation drive unit, which is located on the square base plate 4 and connected to the airbag plane.

[0092] The number of airbag transformation driving units is two sets, and the two sets of airbag planes are respectively connected to both ends of the airbag plane;

[0093] The airbag plane includes a winding drive device 12, a winding shaft 13, and a scraping opening 18.

[0094] The winding drive device 12 is fixedly installed on the square frame base plate 4, and a winding shaft 13 is fixedly installed on the output end of the winding drive device 12. The winding shaft 13 is rotatably connected to the square frame base plate 4.

[0095] The scraping opening 18 is opened on the square frame base plate 4, and scrapes and cleans the airbag plane when it is rolled up and moved.

[0096] It also includes: an arc-shaped smooth part 20, which is fixedly installed on the suspended aquaculture cage 2 and slidably connected to the airbag plane;

[0097] And a limiting protrusion 21, which is disposed at the end of the arc-shaped smooth portion 20 to limit the side of the airbag plane.

[0098] In this invention, the airbag plane of the buoyancy alternation component is composed of a regulating floating airbag 14 made of seawater-resistant butyl rubber and three winding support belts 15, 22, and 23 made of high-strength polyester woven material. The three winding support belts 15, 22, and 23 are separated by a side cleaning opening 16, and the number of regulating floating airbags 14 on each belt increases sequentially to form three different buoyancy levels. The two ends of the airbag plane are connected... A high-pressure resistant polyurethane delivery pipe 24 is provided, with an inflation port 25 and a suction port 26 at the end of the delivery pipe 24, and is connected to an external air source, namely a corrosion-resistant pneumatic device integrating a high-pressure air pump and a vacuum pump. The airbag conversion drive unit uses a mature waterproof stepper motor as the winding drive device 12. Two sets of this drive unit are symmetrically installed on both sides of the square frame base plate 4. The output end of the winding drive device 12 is fixedly connected to the winding shaft 13, and the winding shaft 13 is connected to the square frame base plate 4. With the waterproof bearing rotating connection, under normal working conditions of the suspended aquaculture cage 2, the winding support belt 3 23 is placed at the bottom wall of the suspended aquaculture cage 2. At this time, the regulating floating airbag 14 is filled with an appropriate amount of gas to provide basic buoyancy for the suspended aquaculture cage 2. When the external PLC intelligent control system receives the weight exceeding signal from the limit detector 6, it immediately controls the external air source to perform precise inflation and deflation operations on the regulating floating airbag 14 through the inflation port 25 and the suction port 26 (the regulating floating airbag 14 on the winding shaft 13 cannot expand in the winding state, only the regulating floating airbag 14 placed at the bottom wall of the suspended aquaculture cage 2 can expand). At the same time, it controls the two sets of winding drive equipment 12 to start synchronously, driving the winding shaft 13 to rotate at a uniform speed, realizing the winding and unwinding action of the airbag plane, so that the airbag plane can smoothly slide and switch on the bottom wall of the suspended aquaculture cage 2. By using the difference in the number of regulating floating airbags 14 on different winding support belts, the buoyancy of the suspended aquaculture cage 2 can be precisely adjusted in stages.

[0099] During the sliding of the airbag plane, the two side walls of the suspended aquaculture cage 2 are aligned with the side cleaning openings 16, allowing the brushes on the rotating cleaning cylinder 10 to clean the side walls of the suspended aquaculture cage 2 through the side cleaning openings 16. Simultaneously, the scraping openings 18 on the square frame base plate 4 scrape and clean the surface of the airbag plane (during the winding process), promptly removing sea mud, algae, and other attached materials. This ensures the buoyancy control of the floating airbag 14 and prevents the attached materials from affecting the inflation and deflation efficiency of the airbag 14. Two curved smooth parts 20 made of polytetrafluoroethylene are fixedly installed at the two corners of the suspended aquaculture cage 2, forming a smooth sliding fit with the airbag plane. This significantly reduces friction during the sliding of the airbag plane, preventing wear and leakage, and extending the service life of the airbag. The limiting protrusions 21 at the ends of the curved smooth parts 20 are made of hard, seawater-resistant plastic blocks, which can precisely limit the side of the airbag plane to prevent... The airbag plane shifts left and right during sliding to ensure precise buoyancy adjustment. The buoyancy adjustment of the airbag plane and the sliding cleaning work together. While adjusting the buoyancy of the suspended aquaculture cage 2 to make it move up and down, the roller brush cleaning structure achieves all-round automatic cleaning of the suspended aquaculture cage 2. This replaces the traditional fixed airbag buoyancy adjustment method, realizing precise adjustment of buoyancy levels. It can adaptively adjust according to the actual weight changes of the suspended aquaculture cage 2. Through the linkage design of buoyancy adjustment and cleaning, the suspended aquaculture cage 2 can complete self-cleaning during buoyancy changes without additional manual operation. This greatly improves the automation and intelligence level of the aquaculture device, adapting to the actual production needs of large-scale aquaculture raft-type three-dimensional aquaculture. At the same time, the precise buoyancy adjustment also ensures that the suspended aquaculture cage 2 is always at a suitable water depth, creating a good growth environment for the cultured organisms and facilitating sampling and testing during the aquaculture process.
