Description

Technical Field

[0001] This invention belongs to the field of aquaculture technology, and particularly relates to a self-cleaning aquaculture equipment and method. Background Technology

[0002] Aquaculture is the production activity of breeding, cultivating, and harvesting aquatic plants and animals under human control. It generally includes the entire process from seedling to finished aquatic product under artificial feeding and management. In a broader sense, it can also include aquatic resource enhancement. Aquaculture includes extensive farming, intensive farming, and high-density intensive farming. Intensive farming involves raising aquatic products in smaller bodies of water using feeding and fertilization methods, such as pond fish farming, net cage fish farming, and enclosure aquaculture.

[0003] During the process of raising aquatic products in aquaculture ponds, a large amount of impurities are generated in the ponds, such as floating objects on the surface of the aquaculture water and feces deposited at the bottom of the pond. These impurities reduce water quality and affect the aquaculture effect, thus requiring the ponds to be cleaned. Currently, the aquatic products and aquaculture water are usually removed in advance, and the aquaculture workers manually scoop and clean them. Therefore, the aquaculture water needs to be changed frequently throughout the aquaculture cycle, which results in a large workload for the aquaculture workers and low cleaning efficiency.

[0036] 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.

[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0038] Reference Figures 1-8 As shown, this embodiment provides a self-cleaning aquaculture device, including:

[0039] Culture tank 1, which is a circular pool;

[0040] Partition net 45 is rotatably connected to the inner wall of the breeding tank 1;

[0041] Support 2 is detachably connected to the top surface of the breeding tank 1. A single-axis motor 3 is fixedly installed on the support 2. The output shaft of the single-axis motor 3 is coaxial with the axis of the breeding tank 1. A drive rod 4 is fixedly connected to the output shaft of the single-axis motor 3. A corresponding mounting plate 5 and a first collection component are fixedly connected to the drive rod 4. The mounting plate 5 is located above the breeding tank 1. The first collection component is located below the partition net 45 and is attached to the inner bottom surface of the breeding tank 1. A second collection component is connected below the mounting plate 5. The second collection component is located above the partition net 45 and floats on the surface of the breeding water.

[0042] A dual-axis motor 6 is mounted on the mounting plate 5. The two output shafts of the dual-axis motor 6 are respectively fixed to a first shaft 7 and a second shaft 8. The first shaft 7 is driven to connect to a first conveying component. The first conveying component passes through the partition 45 and is connected to the first acquisition component. The second shaft 8 is driven to connect to a second conveying component. The second conveying component is connected to the second acquisition component.

[0043] Collection box 9 is fixedly connected to mounting plate 5 and is connected to the first conveying component and the second conveying component respectively.

[0044] The aquatic products and impurities accumulated on the bottom of the aquaculture tank 1 are separated by the partition net 45. When it is necessary to clean the impurities in the aquaculture tank 1, the single-axis motor 3 drives the drive rod 4 to rotate, thereby driving the mounting plate 5, the first collection component, the second collection component, and the partition net 45 to rotate circumferentially along the aquaculture tank 1. During the rotation, the first collection component collects the impurities accumulated on the bottom of the aquaculture tank 1, and the second collection component collects the impurities floating on the surface of the aquaculture water in the aquaculture tank. After collection is completed, the dual-axis motor 6 drives the first shaft 7 and the second shaft 8 to rotate synchronously, driving the first conveying component and the second conveying component. Thus, the first conveying component transports the impurities in the first collection component to the collection box 9, and the second conveying component transports the impurities in the second collection component to the collection box 9. This eliminates the need for frequent water changes, replaces manual cleaning, reduces the workload of aquaculture personnel, and improves cleaning efficiency.

[0045] The scheme is further optimized. The first collection component includes a first collection box 10, which is fixedly connected to the drive rod 4. The bottom, one side, and one end near the inside of the breeding tank 1 of the first collection box 10 are open. The bottom of the first collection box 10 is in contact with the inner bottom surface of the breeding tank 1. The end of the first collection box 10 near the inner side wall of the breeding tank 1 is in contact with the inner side wall of the breeding tank 1. The end of the first collection box 10 away from the inner side wall of the breeding tank 1 is rotatably connected to a first collection rod 11. The first collection rod 11 is connected to the second shaft 8 for transmission. A first spiral blade 12 is fixedly connected to the first collection rod 11. The conveying direction of the first spiral blade 12 is from the axis of the breeding tank 1 toward the inner side wall of the breeding tank 1. The first conveying component is located at the end of the first spiral blade 12 near the inner side wall of the breeding tank 1.

[0046] When the first collection box 10 rotates around the circumference of the breeding tank 1, the impurities on the bottom surface of the breeding tank 1 can be collected from its open side into the first collection box 10. And through the rotation of the first spiral blade 12, the impurities can be concentrated and transported to the position of the first conveying component. The first spiral blade 12 can rotate synchronously when the first collection box 10 rotates. The pressure generated between the open surface of the first collection box 10 and the breeding water encapsulates the impurities in the first collection box 10, which causes the first spiral blade 12 to push and transport the impurities.

[0047] The scheme is further optimized by fixing a first driven wheel 13 on the first acquisition rod 11. The first driven wheel 13 is connected to a first driving wheel 15 through a first transmission chain 14. The first driving wheel 15 is fixedly connected to the second shaft 8.

[0048] When the second shaft 8 rotates, it can drive the first collection rod 11 to rotate through the first driving wheel 15, the first transmission chain 14 and the first driven wheel 13, thereby enabling the first spiral blade 12 to perform operations.

[0049] The scheme is further optimized. The first conveying component includes a first conveying cylinder 16. The top end of the first conveying cylinder 16 is fixedly connected to the mounting plate 5. The bottom end of the first conveying cylinder 16 passes through the partition net 45 and the top wall of the first collection box 10 in sequence, and is inserted into the first collection box 10. The first conveying cylinder 16 is connected to the first collection box 10. A first conveying rod 17 is rotatably connected inside the first conveying cylinder 16. A third spiral blade 18 is fixedly connected to the first conveying rod 17. The bottom end of the third spiral blade 18 extends out of the first conveying cylinder 16. The top of the first conveying cylinder 16 is connected to the collection box 9 through a first through pipe 19. A first driven bevel gear 20 is fixedly connected to the top end of the first conveying rod 17. The first driven bevel gear 20 is meshed with a first driving bevel gear 21. The first driving bevel gear 21 is fixedly connected to the first shaft 7.

[0050] When the first spiral blade 12 concentrates and transports the impurities to the position of the third spiral blade 18, they accumulate and come into contact with the third spiral blade 18. The first shaft 7 rotates and drives the first driven bevel gear 20 and the first conveying rod 17 to rotate through the first driving bevel gear 21. Thus, the third spiral blade 18 transports the impurities to the collection box 9 through the first conveying cylinder 16 and the first through pipe 19.

[0051] Further optimizing the scheme, the second acquisition component includes a second acquisition box 22, one side of which is open. A second acquisition rod 23 is rotatably connected inside the second acquisition box 22. The second acquisition rod 23 is connected to the second shaft 8 for transmission. A second spiral blade 24 is fixedly connected to the second acquisition rod 23. The second spiral blade 24 is a bidirectional blade. The conveying direction of the second spiral blade 24 is from both ends toward the middle. The second conveying component is located at the conveying end of the second spiral blade 24.

[0052] When the second collection box 22 rotates around the circumference of the breeding tank 1, it can collect impurities on the surface of the breeding water in the breeding tank 1 from its open side into the second collection box 22. And through the rotation of the second spiral blade 24, the impurities can be concentrated and transported from both ends to the position of the second conveying component in the middle. The second spiral blade 24 can rotate synchronously when the second collection box 22 rotates. The pressure generated between the open surface of the second collection box 22 and the breeding water encapsulates the impurities inside the second collection box 22, which causes the second spiral blade 24 to push and transport the impurities.

[0053] The scheme is further optimized by fixing a second driven wheel 25 on the second acquisition rod 23. The second driven wheel 25 is connected to a second driving wheel 27 through a second transmission chain 26. The second driving wheel 27 is fixedly connected to the second shaft 8.

[0054] When the second shaft 8 rotates, it can drive the second collection rod 23 to rotate through the second driving wheel 27, the second transmission chain 26 and the second driven wheel 25, thereby enabling the second spiral blade 24 to perform operations.

[0055] Further optimizing the design, the second conveying component includes a second conveying cylinder 28, which is fixedly connected to the mounting plate 5. The second conveying cylinder 28 communicates with the second collection box 22 and slides in cooperation with it (to allow the second collection box 22 to float with slight changes in water level, thus keeping a portion of the second collection box 22 submerged in the aquaculture water, facilitating the collection of impurities floating on the surface of the aquaculture water into the second collection box 22). A second conveying rod 29 is rotatably connected inside the second conveying cylinder 28, and a fourth spiral blade 30 is fixedly connected to the second conveying rod 29. The bottom end of the fourth spiral blade 30 extends out of the second conveying cylinder 28 and has a gap between it and the second collecting rod 23 and the second spiral blade 24 (in this way, the fourth spiral blade 30 can avoid collision with the second collecting rod 23 and the second spiral blade 24 when the second collecting box 22 floats up and down). The top of the second conveying cylinder 28 is connected to the collecting box 9 through the second pipe 31. The top end of the second conveying rod 29 is fixedly connected to the second driven bevel gear 32. The second driven bevel gear 32 is meshed with the second driving bevel gear 33. The second driving bevel gear 33 is fixedly connected to the second shaft 8.

[0056] When the second spiral blade 24 concentrates and transports the impurities to the position of the fourth spiral blade 30, they accumulate and come into contact with the fourth spiral blade 30. The second shaft 8 rotates, which drives the second driven bevel gear 32 and the second conveying rod 29 to rotate through the second driving bevel gear 33. Thus, the fourth spiral blade 30 transports the impurities to the collection box 9 through the second conveying cylinder 28 and the second through pipe 31.

[0057] To further optimize the design, multiple guide rods 34 are fixedly connected to the bottom surface of the mounting plate 5. A pair of limiting rings 35 are fixedly connected to the guide rods 34. A sliding ring 36 that slides with the guide rods 34 is provided between the pair of limiting rings 35. The sliding ring 36 is fixedly connected to the second acquisition box 22, and a float 37 is fixedly connected to the outer wall of the second acquisition box 22 away from its open side.

[0058] The buoyancy of the float 37 and the limiting of the sliding ring 36 allow the second collection box 22 to float up and down with the water surface position, and a pair of limiting rings 35 can limit the sliding distance of the second collection box 22.

[0059] The scheme is further optimized. A support plate 38 is fixedly connected to the mounting plate 5. Multiple slide rods 39 slide through the support plate 38. A connecting frame 40 is fixedly connected to one end of the multiple slide rods 39. A spring 41 is sleeved on the slide rod 39 and fixed between the support plate 38 and the connecting frame 40. A tension wheel 42 is rotatably connected to the connecting frame 40. The tension wheel 42 abuts against the second transmission chain 26.

[0060] When the second collection box 22 floats up and down, the second transmission chain 26 can be kept taut by the spring 41, the slide bar 39 and the tension wheel 42.

[0061] Furthermore, the bottom surface of the collection box 9 is mesh, which facilitates the filtration of moisture in the impurities. The side wall of the collection box 9 is rotatably connected by an opening and closing door 43, and a cylinder 44 is hinged between the opening and closing door 43 and the side wall of the collection box 9. The opening and closing door 43 can be opened by the cylinder 44 to clean the impurities in the collection box 9.

[0062] Furthermore, the first transmission chain 14 and the second transmission chain 26 are detachable transmission chains.

[0063] Furthermore, the partition net 45 has a ring structure, and an avoidance hole is provided on the partition net 45 for the first conveying cylinder 16 to pass through. A hollow partition cylinder 46 is fixedly connected to the inner ring of the partition net 45. The top opening of the partition cylinder 46 is higher than the surface of the aquaculture water to prevent aquatic products from being exposed below the partition net 45. The partition cylinder 46 is used to cover the drive rod 4 and the first transmission chain 14. A support ring 47 is provided on the outer ring of the partition net 45. A limiting groove 48 is provided on the inner ring of the support ring 47. A limiting ring 49 is slidably fitted in the limiting groove 48. The limiting ring 49 is fixedly connected to the outer ring of the partition net 45. A connecting ring 50 is fixedly connected to the inner wall of the aquaculture tank 1. The connecting ring 50 and the support ring 47 are detachably connected by bolts during installation.

[0064] Furthermore, the drive rod 4 includes a first stage 51, a second stage 52, and a third stage 53 arranged coaxially. The first stage 51 is fixed between the single-axis motor 3 and the mounting plate 5. One end of the second stage 52 is fixed to the end face of the mounting plate 5 away from the first stage 51. The other end of the second stage 52 is connected to the third stage 53 through the disassembly and assembly part 54. The end of the third stage 53 away from the second stage 52 is fixed to the first acquisition box 10.

[0065] The two ends of the bracket 2 are connected to the top surface of the breeding tank 1 by bolts.

[0066] During installation, the first collection box 10 and the third stage 53 are first placed into the breeding tank 1. Then, the support ring 47 and the connecting ring 50 are fixedly connected, so that the partition net 45 is located above the first collection box 10, and the first transmission chain 14 is in an unspliced ​​state. The third stage 53 and the first transmission chain 14 are located inside the separator cylinder 46. The first conveying cylinder 16 is aligned with the clearance hole on the partition net 45 and inserted. Then, the bracket 2, which has a single-axis motor 3, mounting plate 5, first conveying cylinder 16 and other structures, is connected and fixed to the breeding tank 1. The second stage 52 and the third stage 53 are connected through the disassembly and assembly parts 54. The first transmission chain 14 is spliced ​​and fixed after passing through the mounting plate 5. With this setup, the partition net 45 can separate aquatic products and impurities. Thus, when the water does not need to be changed, when the drive rod 4 rotates, it drives the mounting plate 5 and the first conveying cylinder 16 to push the partition net 45 to rotate along the support ring 47 to clean impurities.

[0067] The disassembly / assembly component 54 is a common rod end connection structure such as a clip or a sleeve with a dowel pin, which will not be described in detail here.

[0068] This embodiment also provides a self-cleaning aquaculture method, including:

[0069] Aquatic products are raised above the partition net 45 inside the breeding tank 1;

[0070] When there is no need to change the aquaculture water, start the single-axis motor 3. The drive rod 4 drives the mounting plate 5, the first collection component, and the second collection component to rotate along the axis of the aquaculture tank 1 to collect impurities on the horizontal surface and bottom of the aquaculture tank 1. The first collection box 10 and the second collection box 22 rotate synchronously to collect impurities on the bottom surface of the aquaculture tank 1 and the surface of the aquaculture water, respectively.

[0071] Simultaneously, the dual-axis motor 6 is started, and the first shaft 7 and the second shaft 8 respectively drive the first conveying component and the second conveying component to transport the impurities in the first collection component and the second collection component to the collection box 9. At the same time, the second shaft 8 drives the first spiral blade 12 and the second spiral blade 24 to rotate through the first transmission chain 14 and the second transmission chain 26, and transports the impurities to the positions of the third spiral blade 18 and the fourth spiral blade 30.

[0072] The collection box 9 is cleaned regularly by opening the door 43 driven by the cylinder 44 for manual cleaning.

[0073] When it is necessary to change the aquaculture water and clean the entire equipment, first remove the aquatic products from the aquaculture tank 1, and then disassemble the equipment and clean it separately.

[0074] Then change the aquaculture water and start feeding the next batch of aquatic products. Repeat the above steps after the aquaculture cycle is completed.
