Description

Technical Field

[0001] This invention relates to the field of disease prevention technology, and specifically to a system for preventing diseases in aquaculture. Background Technology

[0002] As is well known, effective disease prevention and control measures in aquaculture can effectively control the spread and development of diseases, reduce aquaculture costs, improve aquaculture efficiency, stabilize the aquatic product market, and enhance consumer confidence in aquatic products. To facilitate disease prevention in the aquaculture process, we propose a disease prevention system for aquaculture.

[0003] A search revealed that Chinese patent application number CN202123119803.3 discloses a disease prevention device for aquaculture cages. The device generally comprises a frame body, a net body, a water quality regulation unit, a central control unit, an alarm unit, and a water quality monitoring unit. Floats are arranged on the outer side of the frame body. The net body is located around the perimeter of the aquaculture area. The water quality monitoring unit is located at the top of the frame body and includes sampling, detection, and cleaning components. The water quality regulation unit is located inside the frame body and includes heating, drug delivery, and aeration components. The alarm unit is located at the top of the frame body. At the top of the cage, the water quality monitoring unit, water quality regulation unit, and alarm unit are all electrically connected to the central control unit. The main frame is also equipped with a frame expansion unit, which forms multiple independent aquaculture zones through the main frame and the net body during use. This allows for zoned aquaculture, ensuring the density of aquaculture individuals, avoiding overcrowding, and improving the utilization rate of the entire aquaculture cage's internal space. The water quality monitoring unit monitors the water quality in real time, facilitating the assessment of aquaculture diseases and helping to take timely preventative measures based on the actual conditions of the farm.

[0004] While the aforementioned existing technical solutions can achieve aquaculture operations and related environmental monitoring functions, they have significant limitations: First, the solutions employ expensive equipment such as robotic arms, resulting in high initial equipment investment costs; second, the application of water pumps limits water intake points, thus affecting the flexibility of water treatment and sampling testing, and operational efficiency needs further improvement; third, in inland large-scale aquaculture scenarios, pond aquaculture remains the mainstream mode, and the aforementioned robotic arms and water pumps have compatibility issues in pond aquaculture scenarios, such as complex deployment, limited sampling range, and insufficient water treatment coverage, which urgently require further optimization and improvement.

[0020] 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. Example

[0021] Please see Figures 1-15A disease prevention system for aquaculture includes a first tracked vehicle 1, a second tracked vehicle 2, and a sampling structure. A water distribution frame 4 is rotatably connected to the first tracked vehicle 1. A magnetic lifting assembly is installed on the second tracked vehicle 2, and a water suction frame 3 is rotatably connected to the magnetic lifting assembly. Through the cooperation of the first tracked vehicle 1 and the second tracked vehicle 2, a movable carrier structure for the disease prevention system for aquaculture is formed, facilitating the deployment of the water suction belt 7 relative to the pond's edge. The deployment operation is relatively simple, and repositioning is easy. Both the first tracked vehicle 1 and the magnetic lifting assembly are equipped with first servo motors 5, which respectively drive the rotation of the water distribution frame 4 and the water suction frame 3. The sampling structure includes a ring-shaped traction rope 6, on which the water suction belt 7 is installed. Multiple storage cavities 8 are provided within the water suction belt 7, and each of the multiple storage cavities 8 is filled with elastic filler 9. Through the design of the sampling structure, a functional structure for sampling water relative to the pond is formed. When sampling... After the elastic filler 9 inside the structure absorbs water, it drives the circular traction rope 6 to move the water suction belt 7, thereby achieving water sampling in the pond. During the sampling operation, the water quality sampling range in the pond is wider, the water sample is more representative, and the application is less limited. The magnetic lifting assembly includes a lifting plate frame 21 and two diagonal cylinders 22. The lifting plate frame 21 has two diagonal circular holes, and the two diagonal cylinders 22 are slidably connected to the two diagonal circular holes respectively. The two diagonal cylinders 22 are fixedly connected to the second tracked vehicle 2. Two tension springs 23 are installed in the second tracked vehicle 2. The two tension springs 23 are fixedly connected to the bottom end of the lifting plate frame 21. An electromagnetic system is installed between the lifting plate frame 21 and the second tracked vehicle 2. The electromagnetic system includes two electromagnets 24 and two permanent magnets 25. The two permanent magnets 25 are fixedly connected to the second tracked vehicle 2. The two electromagnets 24 are installed on the lifting plate frame 21, and the two electromagnets 24 are matched with the two permanent magnets 25 respectively.

[0022] It should be further explained that a second servo motor 10 is installed on both the water distribution frame 4 and the water suction frame 3. A rope take-up wheel 13 and a rope feed wheel 14 are rotatably connected inside the water distribution frame 4 and the water suction frame 3, respectively. Both the rope take-up wheel 13 and the rope feed wheel 14 are connected to the annular traction rope 6. The two second servo motors 10 are used to drive the rotation of the rope take-up wheel 13 and the rope feed wheel 14, respectively. A water pressure control structure and a feeding control structure are installed inside the water distribution frame 4 and the water suction frame 3, respectively. A water pressure roller 11 and a feeding roller 12 are connected inside the water pressure control structure and the feeding control structure, respectively. The water pressure roller 11 and the feeding roller 12 are... The sampling structure is not connected to the suction belt 7. Two third servo motors 15 are installed outside both the feeding control structure and the pressing control structure. These three third servo motors 15 drive the rotation of the feeding roller 12 and the pressing roller 11, respectively. Through the cooperation of the second servo motor 10, the rope take-up wheel 13, the rope feed wheel 14, the third servo motor 15, the feeding roller 12, and the pressing roller 11, a transmission connection structure is formed between the first tracked vehicle 1 and the second tracked vehicle 2. This facilitates the movement of the sampling structure after absorbing water, and the separation of the water absorbed within the sampling structure from the sampling structure after it is discharged from the pond, thereby achieving… For continuous sampling and processing, it is more practical. Both the water distribution frame 4 and the water suction frame 3 are fixedly connected to the stabilizing frame 26. Each of the two stabilizing frames 26 has an upper opening groove 27 and a lower opening groove 28. The first guide strip 29 and the second guide strip 30 are fixedly connected in the two upper opening grooves 27 and the two lower opening grooves 28. The annular traction rope 6 has a first slot and a second slot. The four first guide strips 29 are slidably connected in the first slot and the four second guide strips 30 are slidably connected in the second slot. Together with the annular traction rope 6, they form the entry rope take-up wheel 13 and the exit rope feed wheel 1. The guide wheel 4 has a bottom-contact wheel 31 rotatably connected inside the water distribution frame 4, and two expansion wheels 32 rotatably connected inside the water suction frame 3. Both the bottom-contact wheel 31 and the two expansion wheels 32 are connected to the annular traction rope 6 for transmission. The bottom-contact wheel 31 guides and turns the annular traction rope 6 to facilitate the turning and guidance of the water suction belt 7 after it enters the water distribution frame 4. The expansion wheels 32 increase the horizontal length of the annular traction rope 6 at the lowest position of the water suction frame 3. On the one hand, this increases the time that the water suction belt 7 is immersed in the water bottom, ensuring that the elastic filler 9 has sufficient contact with the bottom environment of the pond and ensuring effective sampling of the pond bottom.

[0023] Furthermore, both the water pressure control structure and the water feeding control structure include a sliding frame 16. Two third servo motors 15 are respectively mounted outside the two sliding frames 16. The feeding roller 12 and the water pressure roller 11 are rotatably connected inside the two sliding frames 16. The water distribution frame 4 and the water suction frame 3 are respectively provided with an outer sliding groove 18 and an inner sliding groove 17. The two sliding frames 16 are slidably connected in the outer sliding groove 18 and the inner sliding groove 17, and a set of pressure sensors 19 are installed in both the inner sliding groove 17 and the outer sliding groove 18. A set of elastic springs 20 are fixedly connected in both sliding frames 16. The force-bearing surfaces of the two sets of pressure sensors 19 are respectively connected to the two sets of elastic springs. The spring 20 contacts the pressure sensor 19. Both sets of pressure sensors 19 are equipped with central controllers, which are electrically connected to the two second servo motors 10. A water collection tray 33 is fixedly connected inside the first tracked vehicle 1. The bottom end of the water distribution frame 4 extends into the water collection tray 33. The bottom of the water collection tray 33 has a gradient structure, lower in the middle and higher at both ends. An external inclined pipe 34 is connected to the lowest position of the water collection tray 33 to collect and guide the water squeezed out of the elastic filler 9, facilitating the directional and controllable flow of the sampled water. Rotating holes 35 are provided on both the first tracked vehicle 1 and the lifting plate 21. The water distribution frame 4 and the water suction frame 3 are rotatably connected to the two rotating holes 35 respectively. Both drive gears 36 are mounted on the output shaft of the service motor 5. Each drive gear 36 meshes with a driven gear ring 37. The two driven gear rings 37 are fixedly connected to the water distribution frame 4 and the water suction frame 3, respectively. The first tracked vehicle 1 and the second tracked vehicle 2 are respectively fixedly connected to an extension frame 38 and an inner insert frame 39. The extension frame 38 has an insertion slot 40 that matches the inner insert frame 39. The extension frame 38 and the inner insert frame 39 are respectively provided with matching overlapping positioning holes 41 and positioning annular grooves. A winch 42 is detachably mounted on the extension frame 38. A pin connecting frame is fixedly connected to the rope on the winch 42 to facilitate the relative connection and relative positioning between the first tracked vehicle 1 and the second tracked vehicle 2. The function is to achieve relative connection and positioning between the outer frame 38 and the inner frame 39 by inserting the inner frame 39 into the insertion slot 40, and then inserting the outer pin into the coinciding positioning hole 41 and then into the positioning annular groove. This achieves relative connection between the first tracked vehicle 1 and the second tracked vehicle 2. By inserting the pin on the pin connecting frame into the positioning annular groove of the inner frame 39, a detachable traction connection is formed. The winch 42 can then be used to form relative traction between the first tracked vehicle 1 and the second tracked vehicle 2. When the slope of the pond is steep, the winch 42 can be used with ropes to assist the second tracked vehicle 2 in driving into and out of the pond, thereby improving practicality.

[0024] In this embodiment, the first tracked vehicle 1, the second tracked vehicle 2, the first servo motor 5, the second servo motor 10, the third servo motor 15, the electromagnet 24, the central controller, and the pressure sensor 19 are all commercially available conventional devices known to those skilled in the art. In this invention, we simply use them without modifying their structure or function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. Therefore, we will not elaborate on them here. Furthermore, the first tracked vehicle 1 and the second tracked vehicle 2 have autonomous driving capabilities. The first tracked vehicle 1, the second tracked vehicle 2, the first servo motor 5, the second servo motor 10, the third servo motor 15, the electromagnet 24, the central controller, and the pressure sensor 19 are equipped with wireless control handheld terminals, which facilitate operation and control by the operator.

[0025] In summary, the operating principle of this disease prevention system for aquaculture is as follows: During operation, the magnetic lifting assembly first controls the water-absorbing frame 3 to rise relative to the second tracked vehicle 2. Specifically, the electromagnet 24 is energized, generating an electromagnetic field that acts on the permanent magnet 25, creating a repulsive force between the electromagnet 24 and the permanent magnet 25. This overcomes the tension of the tension spring 23, ultimately raising the height of the lifting frame 21 relative to the second tracked vehicle 2. Finally, the water-absorbing frame 3 is raised relative to the second tracked vehicle 2, allowing the water-absorbing belt 7 at its lowest position to... The system raises and lowers the ground surface's influence on the suction belt 7 during the movement of the second tracked vehicle 2. Then, it controls the first tracked vehicle 1 and the second tracked vehicle 2 to move synchronously to the edge of the pond. The first tracked vehicle 1 is then parked at the pond's edge, while the second tracked vehicle 2 drives into the pond until it reaches the bottom and comes to a stop. Before stopping, the relative positions of the first tracked vehicle 1 and the second tracked vehicle 2 need to be adjusted. This is achieved through the operation of two first servo motors 5, which adjust the rotation of the suction frame 3 relative to the second tracked vehicle 2 and the water distribution frame. 4. The rotation adjustment relative to the first tracked vehicle 1 is made so that the water suction belt 7 can be laid flat between the first tracked vehicle 1 and the second tracked vehicle 2, facilitating the smooth transmission of the water suction belt 7 between the pressure roller 11, the feed roller 12, the take-up reel 13, and the feed reel 14. Then, the magnetic lifting assembly is controlled to disable the lifting effect of the water suction frame 3 relative to the second tracked vehicle 2. Under the action of the tension spring 23, the relative height of the water suction frame 3 relative to the second tracked vehicle 2 is then reduced, so that the water suction belt 7 can better immerse itself in the water at the bottom of the pond. Upon contact, two second servo motors 10 and two third servo motors 15 are activated to drive the combined rotation of the water-pressing roller 11, the feeding roller 12, the rope-taking wheel 13, and the rope-feeding wheel 14, thereby creating the motion of the sampling structure. During the motion of the sampling structure, the rope-taking wheel 13 and the rope-feeding wheel 14 work together with the annular traction rope 6 to drive the motion of the annular traction rope 6, which in turn drives the motion of the water-absorbing belt 7 on the annular traction rope 6. The water-pressing roller 11 and the feeding roller 12 work together with the water-absorbing belt 7 to drive the motion of the water-absorbing belt 7.

[0026] Furthermore, during the synchronous movement of the water-absorbing belt 7 and the annular traction rope 6, the elastic fillers 9 in the multiple storage cavities 8 also move synchronously. When the elastic fillers 9 are immersed in water, the void structure within them adsorbs the water. The water-adsorbed elastic fillers 9 move along with the water-absorbing belt 7. As the water-adsorbed elastic fillers 9 approach and pass through the water-distribution frame 4, the pressure roller 11 squeezes the water-absorbing belt 7, causing the water adsorbed within the elastic fillers 9 to be squeezed out. The squeezed-out water falls into the water collection tray 33 and passes through the external inclined tube 34. After being discharged to testing equipment or a water treatment system, the elastic filler 9, having had its water squeezed out, will move along with the water-absorbing belt 7 and approach the second tracked vehicle 2 again. This allows the elastic filler 9 to be re-immersed in the pond, ensuring continuous and consistent water intake. During water intake, the first tracked vehicle 1 and the second tracked vehicle 2 are controlled to move synchronously relative to each other, enabling water intake operations in multiple wading areas within the pond. Because the water-absorbing belt 7, entering the water distribution frame 4, is controlled by the relative rotation of the rope-retracting wheel 13 and the water-pressing roller 11, to ensure the water-pressing roller 11 effectively removes water from the elastic filler... Successful and efficient extrusion and drainage sampling of the filling material 9 allows for the testing of the extruded water, yielding representative water sample data. During operation, it is necessary to maintain the relative tension of the suction belt 7 between the take-up rope wheel 13 and the pressure roller 11. This means that a set of pressure sensors 19, which cooperate with the sliding frame 16 installed in the outer sliding groove 18, must maintain a certain pressure value. When this pressure value decreases, the rotational speed of the take-up rope wheel 13 relative to the pressure roller 11 should be reduced; similarly, when the pressure value increases, the rotational speed of the take-up rope wheel 13 relative to the pressure roller 11 should be increased. The feed roller 12 maintains a certain tension on the suction belt 7 during the process of feeding the suction belt 7 into the water. Therefore, the pressure sensor 19, which is matched with the sliding frame 16 installed in the inner sliding groove 17, is also controlled to be within a certain pressure range. If the pressure is higher than the range, the rotation speed of the feed roller 12 should be appropriately reduced. If the pressure is lower than the range, the rotation speed of the feed roller 12 should be appropriately increased. This process is automatically adjusted by the central controller to ensure that the suction belt 7 has a good operating effect.

[0027] Furthermore, when performing water treatment operations in the pond, the relative positions of the first tracked vehicle 1 and the second tracked vehicle 2 need to be adjusted so that the second tracked vehicle 2 enters the pond and stops at the bottom, while the first tracked vehicle 1 stops at the pond bank. Water treatment agents are placed below the suction frame 3. As the suction belt 7 moves, the elastic filler 9 is first immersed in the agents, and then gradually moves from the water surface to the bottom. During this process, the agents diffuse throughout the water until they reach the bottom, where the pressure roller 11 at the bottom compresses the suction belt 7 to... This allows for better outward drainage of medications within the elastic filler 9. Overall, the bottom of the water is a core area where diseases are more likely to breed and break out. The bottom is the "collection point" of material cycling in aquaculture systems, where uneaten feed, farmed organism excrement, and animal and plant remains continuously accumulate. Under the decomposition of microorganisms, these substances consume large amounts of dissolved oxygen, creating a localized anaerobic environment. This environment not only inhibits the activity of beneficial microorganisms but also promotes the accumulation of toxic and harmful substances such as ammonia nitrogen and hydrogen sulfide, leading to a decline in the immunity of farmed organisms and providing a breeding ground for pathogens such as bacteria, fungi, and parasites. The system provides ideal conditions—for example, the organic matter produced by the decomposition of uneaten feed and feces provides ample nutrients for Vibrio, allowing it to multiply rapidly in the bottom sediment. When farmed organisms come into contact with contaminated sediment or ingest feed containing bacteria, they are prone to diseases such as bacterial enteritis or septicemia. Therefore, targeted disinfection of the bottom environment is necessary. Direct contact of the disinfectant with the pond bottom effectively disinfects the bottom environment, achieving the goal of disease prevention. Since this disease prevention system for aquaculture needs to operate in a wading environment, all its electronic and electrical components (including the first feeder) must be disinfected. The servo motor 5, second servo motor 10, third servo motor 15, electromagnet 24, pressure sensor 19, and central controller, etc., must all be IP68 waterproof standard products, and multiple waterproof protection measures must be implemented. For example, the electronic component housing is sealed with a rubber ring, the cable interface uses a waterproof connector, and a waterproof oil seal is installed at the motor output shaft end to ensure the sealing and protection effect of electronic and electrical components during water immersion operations, ensuring stable system operation. The elastic filler 9 and the water-absorbing belt 7 adopt a detachable locking connection structure to balance the convenience of replacement and operational reliability. Figure 15 As shown, the absorbent belt 7 has a pick-and-place opening on its side, and the storage cavity 8 has a hook-and-loop fastener on its inner side along its length. The elastic filler 9 has a corresponding hook-and-loop fastener. During assembly, the elastic filler 9 is inserted into the receiving cavity of the absorbent belt 7 through the pick-and-place opening. The hook-and-loop fastener and the fastener contact to form a lock, effectively preventing the elastic filler 9 from falling off during water flow impact, pressure roller squeezing, and traction movement. When replacing, the hook-and-loop fastener can be separated to unlock, and the elastic filler 9 can be quickly taken out through the pick-and-place opening. This design not only facilitates the individual replacement of the elastic filler 9 after it is worn out, but also allows for the flexible installation of functional modules such as water quality detection sensors or slow-release agent carriers in the absorbent belt 7 according to operational needs, significantly expanding the applicable scenarios of the system and improving the practicality of the equipment.
