Description

Technical Field

[0001] This invention relates to an aquaculture device, specifically a high-density aquaculture device for Litopenaeus vannamei and its oxygen supply control system, belonging to the field of Litopenaeus vannamei aquaculture technology. Background Technology

[0002] The Pacific white shrimp (Litopenaeus vannamei) is an animal belonging to the genus Litopenaeus in the family Penaeidae of the order Decapoda. It is also known as the white-skinned shrimp or white prawn. The Pacific white shrimp has a thin carapace, a light bluish-gray body color with small spots on its surface; the length of its rostrum tip does not extend beyond the second segment of the first antennal peduncle; the lateral groove of the rostrum is short, disappearing below the gastric spine; the cephalothorax is relatively short, with hepatic spines and gill spines; the fourth to sixth abdominal segments have a dorsal ridge; the telson has a central groove but lacks lateral spines. The average lifespan of the Pacific white shrimp exceeds 32 months. As a high-yield farmed shrimp species highly valued in aquaculture, the Pacific white shrimp has high economic and nutritional value. Due to its thin shell, plump body, warm nature, and sweet taste, it is believed to have kidney-tonifying and aphrodisiac effects, making it very popular.

[0003] Fixed-power aeration equipment should be added to the aquaculture ponds to supply oxygen to the ponds within a specified time, thereby increasing the dissolved oxygen content. The existing aeration equipment is fixed in the pond, resulting in low uniformity of oxygen dissolution and low oxygen content in some areas, leading to inconsistent survival rates of shrimp larvae. At the same time, after a period of rearing, a large amount of silt and bacteria will accumulate in the ponds in greenhouses. If this silt and bacteria are not cleaned in time, it will not only lead to the deterioration of pond water quality, but also significantly affect the growth environment of shrimp larvae, making them prone to outbreaks of shrimp diseases. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] The purpose of this invention is to provide a high-density Litopenaeus vannamei (whiteleg shrimp) farming equipment and its oxygen supply control system to solve the above-mentioned problems. This addresses the issues in the prior art where oxygenation equipment is fixed in the pond, resulting in low oxygen dissolution uniformity and low oxygen content in some areas, leading to inconsistent shrimp larvae survival rates. Furthermore, if silt and bacteria in the pond are not cleaned in a timely manner, it can cause pond water quality deterioration and significantly impact the shrimp larvae's growth environment.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a high-density Litopenaeus vannamei (whiteleg shrimp) aquaculture equipment and its oxygen supply control system, comprising an aquaculture pond, a drain pipe fixedly connected to one side of the bottom of the aquaculture pond, reciprocating screws rotatably connected to both sides of the bottom of the aquaculture pond, a movable seat threadedly connected to the outer side of the reciprocating screws, a threaded sleeve rotatably connected to the top of the movable seat, a threaded tube slidably connected inside the threaded sleeve, a turntable fixedly connected to the top of the threaded tube, multiple connectors fixedly connected in a circular array inside the turntable, telescopic connecting pipes fixedly connected to the input ends of the multiple connectors, nozzles fixedly connected to the output ends of the multiple connectors, multiple nozzles penetrating the side wall of the turntable and fixedly connected to the turntable, multiple telescopic connecting pipes penetrating the threaded tube and movably sleeved with the threaded tube, a flexible hose fixedly connected to the inside of one side wall of the drain pipe, one end of the flexible hose fixedly connected to the movable seat, the flexible hose and the multiple telescopic connecting pipes connected through a rotary joint, a filter screen installed inside the aquaculture pond, and cleaning components installed on both sides of the bottom of the filter screen.

[0008] Preferably, the threaded sleeve has grooves on both sides inside, and the threaded tube has sliders fixedly connected to both sides at the bottom end. The two sliders are slidably connected to the two grooves, so that the grooves limit the sliders, thereby causing the threaded sleeve to drive the sliders to rotate, and thus driving the threaded tube and the threaded sleeve to rotate synchronously.

[0009] Preferably, sleeves are fixedly connected to both sides of the top of the movable seat, and fixed plates are fixedly connected to the top ends of the two sleeves. A first limiting sleeve is fixedly connected inside the fixed plate through a one-way bearing. The threaded tube passes through the first limiting sleeve and is threadedly connected to the first limiting sleeve, so that the first limiting sleeve limits the threaded tube in one direction, allowing the threaded tube to move up and down reciprocally when rotating in this direction. When rotating in the opposite direction, the first limiting sleeve and the threaded tube rotate synchronously. Sliding rods are slidably connected inside the two sleeves, and circular plates are fixedly connected to the top ends of the two sliding rods.

Two first cleaning brushes are fixedly connected to the top two sides of the movable frame, and both first cleaning brushes are in contact with the bottom of the filter screen, so that the movable frame drives the first cleaning brushes to move, thereby cleaning the debris clogging the inside of the filter screen.

[0012] Preferably, the movable frame has multiple rotating rods rotatably connected inside, and cleaning rollers are fixedly connected to the outer sides of each of the multiple rotating rods. The multiple cleaning rollers are all in contact with the bottom of the filter screen. A gear is fixedly connected to one end of each of the multiple rotating rods, and a rack is fixedly connected to one side of the bottom of the filter screen. The multiple gears are meshed with the rack, so that when the movable frame moves, it drives the multiple rotating rods and cleaning rollers to move, and the gears rotate when they move, thereby driving the cleaning rollers to rotate and clean the filter screen.

[0013] Preferably, guide rods are fixedly connected to the four corners inside the aquaculture pond, the filter screen is slidably connected inside the multiple guide rods, the sliding plate is slidably connected inside the filter screen, and take-up cloths are fixedly connected to both sides of the sliding plate. Take-up boxes are fixedly connected to both sides of the bottom of the filter screen. The two take-up cloths are respectively wound into the two take-up boxes by coil springs, so that the take-up cloths cover the filter screen and prevent white shrimp from falling off. A second cleaning brush is fixedly connected to the side of the sliding plate away from the moving frame. The second cleaning brush is in contact with the bottom of the filter screen to clean the side of the filter screen.

[0014] Preferably, multiple limiting rods are fixedly connected inside the aquaculture pool, and limiting plates are fixedly connected to both sides of the movable seat. The limiting rods pass through the limiting plates and are slidably connected to the limiting plates. A servo motor is fixedly connected to one side of the aquaculture pool, and the output end of the servo motor is fixedly connected to a reciprocating lead screw. A detection box is fixedly connected to the front side of the aquaculture pool.

[0015] An oxygen supply control system for high-density whiteleg shrimp includes a controller. The output of the controller is connected to a water tank monitoring module. The output of the water tank monitoring module is connected to a cloud database. The output of the controller is connected to a water quality monitoring module and an oxygen supply control module. The outputs of the water quality monitoring module and the oxygen supply control module are connected to the water tank monitoring module. The output of the controller is also connected to a cleaning control module.

[0016] Preferably, the water tank monitoring module includes a water level sensor, the output of which is connected to a flow sensor, and the output of which is connected to an information transmission unit. The water quality monitoring module includes an oxygen content detector, a water temperature sensor, and a water pH sensor. The oxygen supply control module includes a motor reverse control unit, the output of which is connected to an oxygen transmission unit. The cleaning control module includes a motor forward control unit, the output of which is connected to an inlet pump control unit, and the output of which is connected to an outlet pump control unit.

[0017] This invention provides a high-density Litopenaeus vannamei (whiteleg shrimp) farming equipment and its oxygen supply control system, which has the following beneficial effects:

[0018] 1. This high-density Litopenaeus vannamei (whiteleg shrimp) farming equipment controls an oxygen generator to output oxygen through a flexible hose, which is then transmitted to multiple telescopic connecting pipes and finally sprayed out from multiple connectors and nozzles. This increases the oxygen content in the water and improves the survival rate of the whiteleg shrimp. The equipment controls a forward and reverse motor to start in the forward direction, driving the threaded sleeve to rotate in the forward direction. The threaded sleeve limits the slider through a groove, causing the slider and threaded tube to rotate. Because the threaded tube passes through and is threadedly connected to the first limiting sleeve, and a one-way bearing is provided on the outside of the first limiting sleeve, the first limiting sleeve limits the threaded tube in this direction, causing the threaded tube to move up and down during rotation. This causes the threaded tube to drive the turntable to move, which in turn drives multiple connectors and nozzles to move. When the multiple nozzles rotate, they move up and down.

[0019] 2. This high-density Litopenaeus vannamei (SPF) shrimp farming equipment uses a servo motor to drive a reciprocating screw to rotate, which in turn moves a moving seat. This movement of the moving seat then moves a threaded sleeve, which in turn moves a threaded tube. The threaded tube then moves a turntable, which in turn moves multiple connectors and nozzles. This allows the nozzles to move horizontally within the farming pond while simultaneously rotating and spraying oxygen, improving the uniformity of oxygen distribution and enhancing oxygen diffusion.

[0020] 3. In this high-density Litopenaeus vannamei (SPAV) shrimp farming equipment, when the moving seat moves, it drives the threaded sleeve to move, which in turn drives the sliding plate to move. The sliding plate then drives the moving frame and the second cleaning brush to move, which in turn drives the first cleaning brush to move. The first cleaning brush cleans the bottom of the filter screen, while the second cleaning brush cleans the bottom sides of the filter screen, removing excrement and other impurities that adhere to and clog the inside of the filter screen. When the moving frame moves, it drives multiple rotating rods and cleaning rollers to move. The rotating rods drive multiple gears to move, and since the gears are meshed with racks, they rotate during movement, thereby driving the rotating rods to rotate and the cleaning rollers to rotate. The cleaning rollers rotate as the drain pipe moves to the bottom, cleaning the bottom of the filter screen, improving the cleaning effect and preventing clogging.

[0021] 4. This high-density Litopenaeus vannamei oxygen supply control system activates the water tank monitoring module via a controller. It monitors the water level in the rearing pond using a water level sensor and detects the flow rate in the drain pipe using a flow sensor. A decrease in flow rate may indicate a blockage in the drain pipe. The flow sensor then sends a command to the information transmission unit, which transmits the detected information to the cloud database for data upload. Simultaneously, the controller controls the water quality monitoring module, which in turn controls the oxygen content detector to measure the oxygen content in the water. A water temperature sensor monitors the water temperature. The system performs testing by detecting the pH value of the water using a pH sensor. The controller sends a command to the oxygen supply control module, which in turn starts the reverse motor control unit, causing the motor to start. The controller then sends a command to the oxygen transmission unit, which delivers controlled oxygen into the aquaculture pond, increasing the oxygen content of the water. The controller also sends a command to the cleaning control module, which starts the forward motor control unit, moving the mobile frame to clean the filter screen and prevent clogging. The inlet and outlet pump control units control the inflow and outflow of water into the aquaculture pond, facilitating water changes. Attached Figure Description

[0040] This invention provides a high-density aquaculture equipment for Litopenaeus vannamei and its oxygen supply control system.

[0041] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 and Figure 11 The system includes a breeding pond 1. A drain pipe 2 is fixedly connected to one side of the bottom of the breeding pond 1. A reciprocating screw 3 is rotatably connected to both sides of the bottom of the breeding pond 1. A movable seat 4 is threadedly connected to the outside of the reciprocating screw 3. A threaded sleeve 5 is rotatably connected to the top of the movable seat 4. A threaded tube 6 is slidably connected inside the threaded sleeve 5. A turntable 11 is fixedly connected to the top of the threaded tube 6. Multiple connectors 12 are fixedly connected in a circular array inside the turntable 11. Telescopic connecting tubes 13 are fixedly connected to the input ends of the multiple connectors 12. Nozzles 14 are fixedly connected to the output ends of the multiple connectors 12. Multiple nozzles 14 penetrate the side wall of the turntable 11 and are fixedly connected to the turntable 11. Multiple telescopic connecting tubes 13 penetrate the threaded tube 6 and are movably sleeved with the threaded tube 6. A flexible hose 16 is fixedly connected to the inside of one side wall of the drain pipe 2. One end of the flexible hose 16 is fixedly connected to the movable seat 4. The flexible hose 16 and multiple telescopic connecting tubes 13 are connected through a rotary joint. A filter screen 22 is installed inside the breeding pond 1. Cleaning components are installed on both sides of the bottom of the filter screen 22.

[0042] The threaded sleeve 5 has grooves 32 on both sides inside, and the threaded tube 6 has sliders 33 fixedly connected to both sides at the bottom. The two sliders 33 are slidably connected to the two grooves 32 respectively, so that the grooves 32 limit the sliders 33, thereby causing the threaded sleeve 5 to drive the sliders 33 to rotate, and thus driving the threaded tube 6 and the threaded sleeve 5 to rotate synchronously.

[0043] Both sides of the top of the movable seat 4 are fixedly connected to sleeves 7. The top of the two sleeves 7 are fixedly connected to fixed plates 8. The first limiting sleeve 9 is fixedly connected inside the fixed plate 8 through a one-way bearing. The threaded tube 6 passes through the first limiting sleeve 9 and is threadedly connected to the first limiting sleeve 9, so that the first limiting sleeve 9 limits the threaded tube 6 in one direction, so that the threaded tube 6 moves up and down when rotating in this direction. When rotating in the opposite direction, the first limiting sleeve 9 and the threaded tube 6 rotate synchronously. The two sleeves 7 are slidably connected to slide rods 10. The top of the two slide rods 10 is fixedly connected to circular plates 34. The turntable 11 is rotatably connected to the top of the circular plates 34. The threaded tube 6 passes through the circular plates 34 and is rotatably connected to the circular plates 34. The top of the turntable 11 is fixedly connected to a cover plate 15, so that the slide rods 10 support the circular plates 34 and the circular plates 34 support the turntable 11.

[0044] The threaded sleeve 5 is threadedly connected to a second limiting sleeve 19 on its outer side. The second limiting sleeve 19 is connected to a support plate 18 via a one-way bearing on its outer side. A sliding plate 17 is fixedly connected to the outer side of the support plate 18. Two sleeves 7 pass through both ends of the support plate 18 and are slidably connected to the support plate 18 to limit the support plate 18. When the threaded sleeve 5 rotates in one direction, it drives the support plate 18 and the sliding plate 17 to move up and down reciprocally.

[0045] The cleaning assembly includes a movable frame 26, which is fixedly connected to one side of the sliding plate 17. The movable frame 26 is located at the bottom of the filter screen 22. Two first cleaning brushes 27 are fixedly connected to the top two sides of the movable frame 26. Both first cleaning brushes 27 are in contact with the bottom of the filter screen 22, so that the movable frame 26 drives the first cleaning brushes 27 to move, thereby cleaning the debris clogging the inside of the filter screen 22.

[0046] Multiple rotating rods 28 are rotatably connected inside the movable frame 26. Cleaning rollers 29 are fixedly connected to the outer side of each rotating rod 28. The cleaning rollers 29 are all in contact with the bottom of the filter screen 22. A gear 30 is fixedly connected to one end of each rotating rod 28. A rack 31 is fixedly connected to one side of the bottom of the filter screen 22. The gears 30 are meshed with the rack 31. When the movable frame 26 moves, it drives the multiple rotating rods 28 and the cleaning rollers 29 to move, and the gears 30 rotate when moving, thereby driving the cleaning rollers 29 to rotate and clean the filter screen 22.

[0047] Guide rods 23 are fixedly connected to the four corners of the breeding pond 1. The filter screen 22 is slidably connected to the inside of the multiple guide rods 23. The sliding plate 17 is slidably connected to the inside of the filter screen 22. The two sides of the sliding plate 17 are fixedly connected to the winding cloth 24. The two sides of the bottom of the filter screen 22 are fixedly connected to the winding box 25. The two winding cloths 24 are respectively wound into the two winding boxes 25 by the coil spring, so that the winding cloths 24 cover the filter screen 22 to prevent the white shrimp from falling. The side of the sliding plate 17 away from the moving frame 26 is fixedly connected to the second cleaning brush 37. The second cleaning brush 37 is attached to the bottom of the filter screen 22 to clean the side of the filter screen 22.

[0048] Multiple limiting rods 21 are fixedly connected inside the breeding pool 1. Limiting plates 20 are fixedly connected to both sides of the movable seat 4. The limiting rods 21 pass through the limiting plates 20 and are slidably connected to the limiting plates 20. A servo motor 35 is fixedly connected to one side of the breeding pool 1. The output end of the servo motor 35 is fixedly connected to the reciprocating lead screw 3. A detection box 36 is fixedly connected to the front side of the breeding pool 1.

[0049] Specifically, the movable base 4 is equipped with a forward and reverse motor, and its output end is connected to the threaded sleeve 5. The oxygen content of the water in the breeding pond 1 is monitored by the detection box 36. When the oxygen content at the monitoring point is less than the set value, the oxygen generator is controlled to output oxygen to the hose 16 and transmit the oxygen to the multiple telescopic connecting pipes 13. Finally, the oxygen is sprayed out from the multiple connectors 12 and nozzles 14 to increase the oxygen content in the water and improve the survival rate of white shrimp. The forward and reverse motor is controlled to start forward, driving the threaded sleeve 5 to rotate forward, so that the threaded sleeve 5 passes through the sliding... The groove 32 limits the slider 33 and drives the slider 33 and the threaded tube 6 to rotate. Because the threaded tube 6 passes through the first limiting sleeve 9 and is threadedly connected to the first limiting sleeve 9, and a one-way bearing is provided on the outside of the first limiting sleeve 9, the first limiting sleeve 9 limits the threaded tube 6 in this direction, so that the threaded tube 6 moves up and down reciprocally when rotating, thereby causing the threaded tube 6 to drive the turntable 11 to move, and causing the turntable 11 to drive multiple connectors 12 and nozzles 14 to move. When the multiple nozzles 14 rotate, they move up and down.

[0050] The servo motor 35 starts and drives the reciprocating screw 3 to rotate, which in turn drives the moving seat 4 to move. When the moving seat 4 moves, it drives the threaded sleeve 5 to move, which in turn drives the threaded tube 6 to move. The threaded tube 6 drives the turntable 11 to move, which in turn drives the multiple connectors 12 and nozzles 14 to move. When the multiple nozzles 14 move up and down and rotate in the water to spray oxygen, they move horizontally inside the aquaculture pond 1, which helps to improve the uniformity of oxygen distribution in the water and increase the oxygen diffusion effect.

[0051] When the movable seat 4 moves, it drives the threaded sleeve 5 to move, which in turn drives the sliding plate 17 to move. The sliding plate 17 then drives the movable frame 26 and the second cleaning brush 37 to move. The movable frame 26 then drives the first cleaning brush 27 to move, allowing the first cleaning brush 27 to clean the bottom of the filter screen 22. At the same time, the second cleaning brush 37 cleans the bottom side of the filter screen 22, removing the excrement and other impurities that adhere and clog the inside of the filter screen 22. When the movable frame 26 moves, it drives multiple rotating rods 28 and cleaning rollers 29 to move. When the multiple rotating rods 28 move, they drive multiple gears 30 to move. Since the multiple gears 30 are all meshed with the rack 31, the gears 30 rotate when they move, thereby driving the multiple rotating rods 28 to rotate and driving the multiple cleaning rollers 29 to rotate. When the multiple cleaning rollers 29 move at the bottom of the drain pipe 2, they rotate and clean the bottom of the filter screen 22, improving the cleaning effect and preventing clogging.

[0052] When the forward and reverse motors rotate in reverse, they drive the threaded sleeve 5 to rotate in reverse. A one-way bearing is provided between the second limiting sleeve 19 and the sliding plate 17. When the threaded sleeve 5 rotates in the reverse direction, the one-way bearing limits the second limiting sleeve 19, thereby causing the threaded sleeve 5 to drive the second limiting sleeve 19 to move up and down. This causes the second limiting sleeve 19 to drive the sliding plate 17 to move. When the sliding plate 17 moves, it drives the filter screen 22 to move, which helps the filter screen 22 to lift the white shrimp located on top of it upwards. Then, the water inside the breeding pond 1 is drawn from the bottom through the drain pipe 2 to discharge the impurities that have settled at the bottom, improve the water quality, and then the water inside the breeding pond 1 is drained again, making water replacement convenient and quick.

[0053] Please refer to the oxygen supply control system for high-density Litopenaeus vannamei. Figure 12 , Figure 13 , Figure 14 , Figure 15 and Figure 16 The system includes a controller 100, an output terminal of which is connected to a water tank monitoring module 200, an output terminal of which is connected to a cloud database 500, an output terminal of which is connected to a water quality monitoring module 300 and an oxygen supply control module 400, and the output terminals of the water quality monitoring module 300 and the oxygen supply control module 400 are connected to the water tank monitoring module 200. The output terminal of the controller 100 is also connected to a cleaning control module 600.

[0054] The water tank monitoring module 200 includes a water level sensor 201, the output of which is connected to a flow sensor 202, and the output of which is connected to an information transmission unit 203. The water quality monitoring module 300 includes an oxygen content detector 301, a water temperature sensor 302, and a water pH sensor 303. The oxygen supply control module 400 includes a motor reverse control unit 401, the output of which is connected to an oxygen transmission unit 402. The cleaning control module 600 includes a motor forward control unit 601, the output of which is connected to an inlet pump control unit 602, and the output of which is connected to an outlet pump control unit 603.

[0055] Specifically, the controller 100 activates the water tank monitoring module 200, which monitors the water level in the aquaculture pond 1 via the water level sensor 201 and detects the flow rate inside the drain pipe 2 via the flow sensor 202. A decrease in flow rate may indicate a blockage in the drain pipe 2. When the flow sensor 202 sends a command to the information transmission unit 203, the unit transmits the detected information to the cloud database 500 for data upload. Simultaneously, the controller 100 controls the water quality monitoring module 300, which in turn controls the oxygen content detector 301 to detect the oxygen content in the water. The water temperature sensor 302 also detects the water temperature. pH sensor 303 detects the pH value in the water. Controller 100 sends a command to oxygen supply control module 400, causing oxygen supply control module 400 to start motor reverse control unit 401, thus starting the motor. Controller 100 also sends a command to oxygen transmission unit 402, causing oxygen to be delivered to the aquaculture pond 1, increasing the oxygen content of the water. Controller 100 then sends a command to cleaning control module 600, causing motor forward control unit 601 to start the motor and move the moving frame 26 to clean the filter screen 22 and prevent clogging. Inlet pump control unit 602 and outlet pump control unit 603 control the inflow and outflow of water into the aquaculture pond 1, facilitating water changes.
