[0028] Factory-farmed crayfish have the advantages of low carbon, high density, high efficiency, and not being affected by natural environment such as climate and water quality changes. At the same time, they can effectively isolate diseases and control the invasion of pathogens, greatly reducing the risk of disease outbreaks during aquaculture. However, factory-farmed crayfish have the risk of collecting dead shrimp shells and leftover bait and feces, which can easily clog the sewage tank, causing the aquaculture water to be polluted and leading to the risk of mass death of crayfish.

[0029] In order to solve the above technical problems, refer to Figure 1-Figure 8The embodiment of the present application provides a crayfish factory breeding device 100 including a box body 10, a partition plate 20 and a sewage discharge device 30. The box body 10 has a first wall 11 and a second wall 12 arranged opposite to each other in the height direction X, the second wall 12 is located below the first wall 11, and the inner surface of the second wall 12 is recessed to form a sewage discharge trough 102 for use, and one end of the sewage discharge trough 102 is connected to the outside. The partition plate 20 is arranged in the box body 10 to divide the interior of the box body 10 into at least two breeding spaces 101, and the sewage discharge trough 102 extends along the length direction Y of the box body 10 to pass through the breeding spaces 101 in sequence. The sewage discharge device 30 can be movably arranged in the sewage discharge trough 102, the partition plate 20 includes an isolation body 21 and an isolation ground door 22, the isolation ground door 22 is rotatably arranged in the isolation body 21, and at least part of the isolation ground door 22 is accommodated in the sewage discharge trough 102, and the sewage discharge device 30 abuts against the isolation ground door 22 to drive the isolation ground door 22 to rotate toward the isolation body 21.

[0030] The box body 10 is a shell for providing a stable breeding environment. By providing the box body 10, the breeding device is modularized so that the device can be arranged according to the actual situation of the breeding factory.

[0031] The isolation plate 20 is a plate-like member arranged in the box body 10 for dividing the internal space of the box body 10. The isolation plate 20 allows the crayfish to be divided, thereby reducing the risk of crayfish gathering in the same area, causing cannibalism and death of the crayfish.

[0032] In some embodiments, a plurality of isolation plates 20 are spaced apart along the length direction Y of the box body 10 to divide the interior of the box body 10 into a plurality of breeding spaces 101 , wherein the breeding spaces 101 are used to contain breeding water and crayfish.

[0033] The sewage discharge device 30 is a plate-shaped member disposed in the sewage discharge tank 102 and adapted to the sewage discharge tank 102 .

[0034] In some embodiments, a linear module is installed at the bottom of the drain trough 102 , and the linear module can drive the drain device 30 to move along the extension direction of the drain trough 102 .

[0035] It can be understood that the sewage discharge device 30 moves along the sewage discharge trough 102 to drive the residual bait, feces, dead shrimp shells and other solids in the sewage discharge trough 102 to move.

[0036] In the present embodiment, since the sewage discharge device 30 can move along the sewage trough 102, the solids in the sewage trough 102 can be driven to move during the movement of the sewage discharge device 30 along the sewage trough 102. At the same time, since the sewage discharge device 30 abuts against the isolation ground door 22, the isolation ground door 22 can be driven to rotate, so that the solids can pass through the isolation ground door 22 through the isolation plate 20, and then be collected at one end of the sewage trough 102, thereby reducing the risk of blockage of the sewage trough 102, thereby improving the water quality and increasing the survival rate of crayfish.

[0037] According to some embodiments of the present application, the crayfish factory farming device 100 further includes a pulley 31 and a traction rope 32. The pulleys 31 are two respectively disposed at both ends of the sewage tank 102. The traction rope 32 is sleeved outside the two pulleys 31 and connected to the sewage device 30. The traction rope 32 moves relative to the pulley 31 to drive the sewage device 30 to move relative to the sewage tank 102.

[0038] It can be understood that the traction rope 32 located on one side of the pulley 31 can pass through the sewage discharge device 30 and can drive the sewage discharge device 30 to move, and the traction rope 32 located on the other side of the pulley 31 can pass through the sewage discharge device 30 and move relative to the sewage discharge device 30. Therefore, when the traction rope 32 moves relative to the pulley 31, the sewage discharge device 30 can be driven to move relative to the sewage discharge tank 102.

[0039] In some embodiments, the pulley 31 can be driven to rotate by a driving motor, and the friction between the pulley 31 and the traction rope 32 can be used to drive the traction rope 32 to move, thereby driving the sewage discharge device 30 to move relative to the sewage tank 102.

[0040] In this embodiment, the sewage discharge device 30 is driven to move by the pulley 31 and the traction rope 32, and the structure is simple and easy to implement.

[0041] According to some embodiments of the present application, the crayfish factory farming device 100 further includes a shrimp nest 40 and a water sprayer 50. The shrimp nest 40 is disposed in the farming space 101. The water sprayer 50 is disposed in the farming space 101, and the water sprayer 50 has a nozzle 51, and the water sprayer 50 is used to drive the farming water in the farming space 101 to move toward the shrimp nest 40 through the nozzle 51. Along the width direction Z of the box body 10, the shrimp nest 40 is located between the nozzle 51 and the sewage tank 102.

[0042] The shrimp nest 40 is a device in the device for the crayfish to rest. It is generally hollowed out to facilitate the entry of the breeding water into the shrimp nest 40 .

[0043] The sprinkler 50 may be a water pump having a water suction end and a water spray end, wherein the water suction end is arranged in the aquaculture water for extracting the aquaculture water, and the nozzle 51 is arranged at the water spray end for providing the aquaculture water to the shrimp nest 40 for cleaning the shrimp nest 40 .

[0044] In some embodiments, the shrimp nests 40 are arranged in two rows on both sides of the drain trough 102 along the width direction Z of the box body 10 , and each row of shrimp nests 40 is arranged in a plurality along the length direction Y.

[0045] In this embodiment, the shrimp nest 40 is located between the nozzle 51 and the drainage trough 102 along the width direction Z of the box 10. Therefore, the aquaculture water provided by the nozzle 51 flows out of the shrimp nest 40 and drives the debris to move toward the drainage trough 102, thereby causing the debris to enter the drainage trough 102.

[0046] According to some embodiments of the present application, a guide surface 103 is provided on the inner surface of the second wall 12 , and the guide surface 103 is used to guide the debris to move from the shrimp nest 40 to the sewage trough 102 .

[0047] In this embodiment, the guide surface 103 is provided to reduce the risk of debris staying in the non-discharge area on the inner surface of the second wall 12 during the cleaning process.

[0048] According to some embodiments of the present application, the box body 10 has a third wall 13 in the width direction Z, and the sprinkler 50 is movably disposed on the inner surface of the third wall 13 along the length direction Y. The isolation plate 20 further includes an isolation side door 23, and a first gap 104 for the sprinkler 50 to pass through is disposed between the isolation body 21 and the third wall 13 in the width direction Z. The isolation side door 23 is slidably disposed on the isolation body 21 along the width direction Z, and is used to open and close the first gap 104.

[0049] The isolation side door 23 can be driven by a cylinder, a linear module, a hydraulic cylinder, an electric telescopic rod and other driving elements to move along the width direction Z. This prevents the crayfish from being gathered in the first gap 104, causing uneven distribution of the crayfish and causing them to kill each other.

[0050] In some embodiments, the sprinkler 50 may include a first battery (not shown in the figure). The sprinkler 50 is driven by a motor to move. The sprinkler 50 absorbs water from the breeding pond through a water pump and sprays water to clean the shrimp nest 40. The power comes from the first battery carried by the sprinkler 50 itself. When the sprinkler 50 stops working, it automatically moves to one end of the box 10 and contacts the first charging pile on this side of the box 10 to charge the first battery so that the sprinkler 50 can start working normally next time.

[0051] In this embodiment, the sprinklers 50 are arranged on the inner surface of the third wall 13 so as to be movable along the length direction Y, thereby reducing the number of sprinklers 50 and simplifying the structure of the device.

[0052] According to some embodiments of the present application, the crayfish factory farming device 100 further includes a feeding and medicine feeding device 60. The feeding and medicine feeding device 60 is movably disposed on the inner surface of the first wall 11 along the length direction Y, and is used to feed and medicine into the farming space 101. A second gap 105 is provided between the isolation body 21 and the first wall 11 in the height direction X for the feeding and medicine feeding device 60 to pass through.

[0053] The feeding and medicine feeding device 60 can be an automatic feeding machine or a granular feeding machine, which is mainly used to accurately feed the bait or medicine to a specified area. This device can improve the efficiency of feeding and medicine feeding, reduce waste, and ensure that the bait or medicine can be evenly distributed, thereby improving the breeding effect.

[0054] In some embodiments, the feed and medicine dispenser 60 may include a second battery (not shown in the figure). The feed and medicine dispenser 60 is driven by a motor to move. The feed and medicine dispenser 60 is connected to the breeding space 101 to put feed or medicine. The power comes from the second battery carried by the feed and medicine dispenser 60 itself. When the feed and medicine dispenser 60 stops working, it automatically moves to one end of the box 10 and contacts the second charging pile on this side of the box 10 to charge the second battery so that the feed and medicine dispenser 60 can start working normally next time.

[0055] In the present embodiment, the bait and medicine feeding device 60 is arranged to be movable along the length direction Y, thereby reducing the number of the bait and medicine feeding devices 60 and simplifying the structure of the device.

[0056] According to some embodiments of the present application, the crayfish factory breeding device 100 further includes a feeding table 70 and a climbing frame 80. The feeding table 70 is arranged on the inner surface of the second wall 12, and at least part of the orthographic projection of the motion trajectory of the feeding and drug feeding device 60 on the second wall 12 overlaps with the orthographic projection of the feeding table 70; the climbing frame 80 is used for the crayfish to climb, and is arranged above the sewage tank 102. In the width direction Z, the feeding table 70 is located between the shrimp nest 40 and the climbing frame 80.

[0057] According to some embodiments of the present application, the box body 10 is a plurality of boxes 10 stacked along the height direction X thereof.

[0058] This makes it easier to utilize the space in the factory height direction X, thereby making rational use of the space within the factory and improving site utilization.

[0059] The embodiment of the present application provides a breeding system 1000, which includes the crayfish factory breeding device 100 provided in any of the above embodiments, a raw water treatment device 900, a water quality detection device 200, a water temperature control device 300 and an oxygenation device 400. The raw water treatment device 900 is connected to the water source and the crayfish factory breeding device 100 respectively, and the breeding water of the water source enters the crayfish factory breeding device 100 through the raw water treatment device 900. The raw water treatment device 900 is used to adjust the water quality of the breeding water of the water source. The water quality detection device 200 is used to detect the water quality of the breeding water in the crayfish factory breeding device 100. The water temperature control device 300 is used to adjust the water temperature of the breeding water in the crayfish factory breeding device 100. The oxygenation device 400 is used to discharge oxygen into the crayfish factory breeding device 100.

[0060] The raw water treatment device 900 may include a grid and a sedimentation tank, wherein the grid is used to filter out large particles of impurities, such as leaves, plastics, etc. The sedimentation tank is used to remove suspended matter and silt in the water through natural sedimentation. At the same time, the pH value in the sedimentation tank can be adjusted by acid and alkali to make the aquaculture water of the water source suitable for crayfish farming.

[0061] The water quality detection device 200 may be an online water quality monitoring system, which is used to monitor multiple parameters in the water body, such as pH value, dissolved oxygen, turbidity, ammonia nitrogen, total phosphorus, total nitrogen, etc. At the same time, the dissolved oxygen content in the water body can be measured to reflect the oxygen enrichment degree of the water body.

[0062] The water temperature control device 300 may include a temperature sensor and a thermostat. The temperature sensor is used to collect the temperature of the aquaculture water, and the thermostat is used to automatically adjust the water temperature to keep it within a set temperature range. Lobsters are temperature-changing animals, and temperature changes can cause stress reactions in crayfish. By setting the water temperature control device 300, the risk of self-harm caused by the stress reaction of crayfish is reduced, thereby improving the survival rate of crayfish.

[0063] The oxygen-increasing device 400 is an aeration device used to inject air into the aquaculture water to increase the oxygen content in the aquaculture water.

[0064] It should be noted that the above-mentioned devices and structures are all prior art and will not be described in detail here.

[0065] According to some embodiments of the present application, the breeding system 1000 further includes a static filter 500, a biochemical treatment device 600, an ultraviolet sterilizer 700, and a dehydration and solidification device 800. The static filter 500 is connected to the sewage tank 102 of the crayfish factory breeding device 100, and is used to filter the solids in the sewage discharged by the crayfish factory breeding device 100. The biochemical treatment device 600 is used to treat harmful substances in the sewage filtered by the static filter 500, and the sewage filtered by the static filter 500 enters the biochemical treatment device 600, and / or enters the crayfish factory breeding device 100. The ultraviolet sterilizer 700 is used to provide ultraviolet rays to the sewage treated by the biochemical treatment device 600, and the sewage treated by the biochemical treatment device 600 enters the crayfish factory breeding device 100 after passing through the ultraviolet sterilizer 700. The dehydration and solidification device 800 is used to dehydrate the solids filtered out by the static filter 500.

[0066] The static filter 500 removes suspended particles and impurities in the water through materials such as filter screens and filter cotton.

[0067] The biochemical treatment device 600 may be a biological filter, in which microorganisms are used to decompose organic matter and ammonia nitrogen in the water. At the same time, aquatic plants (such as water hyacinth, water plantain, etc.) may be added to the biological filter to absorb nutrients and pollutants in the water.

[0068] The ultraviolet sterilizer 700 is used to provide ultraviolet rays to the sewage treated by the biochemical treatment device 600 to disinfect the aquaculture water.

[0069] The dehydration and solidification device 800 can be one or more of a filter press, a centrifuge or an air dryer, and is a device used to treat water-containing substances to remove water therefrom and solidify them into a solid form.

[0070] Exemplarily, 2 / 3 of the clean water filtered by the static filter 500 is directly sent back to the housing 10 (a small amount of which enters the external sewage regulating tank 1100 for water adjustment), and 1 / 3 of the clean water after filtration enters the biochemical treatment device 600. The biochemical treatment device 600 uses porous suspended fillers to decompose 1 / 3 of the aquaculture water flowing from the static filter 500, and treats harmful substances such as ammonia nitrogen, nitrates, and nitrites in the water. Then, it is sterilized and disinfected by the ultraviolet sterilizer 700 equipped with a self-cleaning device and returned to the housing 10. The dehydration and solidification device 800 collects the residual bait, feces, dead shrimps, shrimp shells and other dirt filtered by the static filter 500 and the dirt discharged by the biochemical treatment device 600, and then dehydrates and solidifies them and hands them over to social treatment to avoid polluting the water body and reduce the labor load. The very small amount of excessive sewage discharged by the dehydration and solidification device 800 enters the external sewage regulating tank 1100 and is diluted with the clean water filtered by the static filter 500 to meet the discharge standards.

[0071] It should be noted that the above-mentioned devices and structures are all prior art and will not be described in detail here.
