Detailed implementation manners

[0019] In order to clearly and completely describe the purpose, technical solution of the present invention and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] Please refer to Figures 1 to 11 , the present invention provides a technical solution: Embodiment 1, a waste cleaning device for the cultivation of penaeus vannamei larvae, comprising: an installation base 8.

[0021] Specifically, a filter cylinder 1 that rotates around it is arranged on the outer side of the installation base 8. The filter cylinder 1 is suspended by itself and does not contact the bottom of the cultivation pond. A fixed cylinder 11 is fixedly penetrated through the middle of the filter cylinder 1. Both ends of the fixed cylinder 11 are connected to the outside of the filter cylinder 1. An installation collar 4 is movably sleeved on the outside of the fixed cylinder 11. The installation collar 4 can rotate around the fixed cylinder 11 in the inner cavity of the filter cylinder 1. An annular partition 41 is fixedly connected to the middle of the installation collar 4, and the annular partition 41 divides the inner cavity of the filter cylinder 1 into two compartments. A first fan blade 42 and a second fan blade 43 are respectively fixed on both sides of the annular partition 41. As Figure 4 shown, after the inner cavities of the two compartments on the left and right sides of the filter cylinder 1 are separated by the annular partition 41, the water flows in the two compartments will not exchange with each other; Secondly, a water suction pipe 2 and a drain pipe 3 are fixedly connected to the outside of the filter cartridge 1, and both the water suction pipe 2 and the drain pipe 3 are tangent to the filter cartridge 1. The water suction pipe 2 and the drain pipe 3 are respectively located in the upper half and the lower half of the filter cartridge 1. The water suction pipe 2 and the drain pipe 3 are respectively communicated with two compartments inside the filter cartridge 1. The flow directions of the water flows in the inner cavities of the water suction pipe 2 and the drain pipe 3 are opposite. However, since they are respectively in the upper and lower halves of the filter cartridge 1, the directions of rotation of the first fan blade 42 and the second fan blade 43 when impacted by the water flow are the same. A curved surface filter screen 21 is arranged in the inner cavity at one end of the water suction pipe 2, a water suction port 22 is arranged on the surface of the water suction pipe 2, and a drain port 31 is arranged on the surface of the drain pipe 3 and the drain port 31 inclines downward. The water suction pipe 2 is mainly used to absorb the water at the bottom of the breeding pond, so that the waste in the water can flow along with the water flow. The curved surface filter screen 21 is arranged to filter and separate the waste in the water flow. The water flow inside the drain pipe 3 can be sprayed out through the drain port 31 and sprayed on the bottom of the breeding pond to stir up the waste at the bottom of the breeding pond, so that the waste can float in the water and be easily sucked away by the water suction pipe 2. Since the drain port 31 inclines downward, when the drain port 31 sprays the water flow, the reaction force generated by the water flow on the drain pipe 3 can, on the one hand, push the whole drain pipe 3 and the water suction pipe 2 to move (i.e., rotate around the mounting base 8), and on the other hand, can also generate a certain lifting force on the whole drain pipe 3 and the water suction pipe 2 to prevent the drain pipe 3 and the water suction pipe 2 from dropping and getting stuck at the bottom of the breeding pond.

[0022] To supplement the description of the first fan blade 42 and the second fan blade 43, the water suction pipe 2 of the present application corresponds to the second fan blade 43. The second fan blade 43 is inclined. When the water flow in the inner cavity of the water suction pipe 2 flows, it impacts on the surface of the second fan blade 43 and makes it rotate. The drain pipe 3 corresponds to the first fan blade 42. The first fan blade 42 is parallel to the axis of the mounting collar 4. One end of the surface of the mounting collar 4 is provided with a pressure stabilizing small hole 44, and the pressure stabilizing small hole 44 and the second fan blade 43 are distributed at intervals. One end of the surface of the fixed cylinder 11 is provided with a notch groove 111, and the notch groove 111 is located in the lower half of the fixed cylinder 11. As Figure 5 and Figure 6 shown, the pressure stabilizing small hole 44 and the notch groove 111 are mainly used to maintain the water pressure stability in one inner cavity of the filter cartridge 1. Since the second fan blade 43 is inclined by itself, when the second fan blade 43 rotates, it will push the water body to have a tendency to move away from the annular partition 41.

[0023] In order to discharge the waste in the inner cavity of the filter cartridge 1, the curved filter screen 21 of the present application is located at a connection port between the water suction pipe 2 and the filter cartridge 1. The curved filter screen 21 is flush with the inner wall of the filter cartridge 1. After the curved filter screen 21 filters and separates the waste in the inner cavity of the filter cartridge 1, when the second fan blade 43 rotates, the edge of the second fan blade 43 can scrape the waste on the surface of the curved filter screen 21, so that the waste can rotate and move together with the second fan blade 43. A slag discharge port 12 is provided in the lower half of one side surface of the filter cartridge 1, and the slag discharge port 12 corresponds to the second fan blade 43. Combining Figure 4 , Figure 5 and Figure 6 as shown, the pressure stabilizing small hole 44 at the upper half of the mounting collar 4 will be blocked by the fixed cylinder 11. At this time, the water flow in the inner cavity of the fixed cylinder 11 will not enter the inner cavity of the filter cartridge 1. After the pressure stabilizing small hole 44 at the lower half of the mounting collar 4 corresponds to the notch groove 111, the water flow in the inner cavity of the fixed cylinder 11 can sequentially pass through the notch groove 111 and the pressure stabilizing small hole 44 and enter the inner cavity of the filter cartridge 1. As mentioned above: Since the second fan blade 43 is inclined by itself, when the second fan blade 43 rotates, it will push the water body to have a tendency to move away from the annular partition 41. Therefore, the water body at the lower half position in the inner cavity of one side of the filter cartridge 1 will be discharged from the slag discharge port 12 under the thrust of the second fan blade 43, so as to facilitate the water flow to carry the waste and discharge it from the inner cavity of the filter cartridge 1 together. A magnet sheet 13 is fixed on one side surface of the filter cartridge 1, and a hollow collection tray 14 is arranged outside the filter cartridge 1. The hollow collection tray 14 is adsorbed on the magnet sheet 13, and the inner cavity of the hollow collection tray 14 is communicated with the slag discharge port 12. A filter plate 15 is movably inserted into the middle of the inner cavity of the hollow collection tray 14 from top to bottom. The hollow collection tray 14 is provided for collecting waste. The filter plate 15 in the inner cavity of the hollow collection tray 14 can be used to filter and separate the waste and the water flow. The water flow can flow into the breeding pond, while the waste remains in the inner cavity of the hollow collection tray 14. After the device is used for a long time, the hollow collection tray 14 can be removed regularly and the waste can be cleaned up.

[0024] In order to supply oxygen to the water body in the breeding pond, the water suction ports 22 of the present application are arranged on both sides of the surface of the water suction pipe 2. The water suction ports 22 are flat with an outward-opening opening. The opening of the water suction ports 22 is large, which is convenient for extracting waste. The drain port 31 is located on one side of the drain pipe 3 close to the water suction pipe 2. The drain port 31 is flat with a closed end. The closed-end structure of the drain port 31 makes the sprayed water flow faster, which can improve the impact effect on the waste at the bottom of the breeding pond and avoid waste accumulation. An air supply pipe 5 is fixedly installed outside the drain pipe 3. A plurality of nozzles 51 are arranged at equal intervals on the surface of the air supply pipe 5. The air supply pipe 5 is mainly used to supply oxygen to the water body in the breeding pond. And since the air supply pipe 5 itself is a hollow structure, the buoyancy generated by the water body on the air supply pipe 5 can offset the gravity of the entire drain pipe 3 and the water suction pipe 2 to a certain extent.

[0025] To support the entire suction pipe 2 and drain pipe 3, the present application further has a rolling disk 7 provided on the outer side of the other end of the suction pipe 2. A hollow shaft 71 is fixedly penetrated through the middle of the rolling disk 7. A connecting plate 72 is movably sleeved on the outer side of the hollow shaft 71. The two ends of the connecting plate 72 are respectively fixedly connected to the suction pipe 2 and the drain pipe 3. The hollow shaft 71 and the air supply pipe 5 are kept in communication through a connecting pipe 6. The rolling disk 7 is mainly used to support the entire suction pipe 2 and drain pipe 3, so that when the suction pipe 2 and the drain pipe 3 rotate and move around the installation base 8, the rolling disk 7 can roll on the bottom of the breeding pond.

[0026] To prevent the gas in the inner cavity of the air supply pipe 5 from easily entering the inner cavity of the connecting pipe 6, the present application further has a rotary joint 61 provided at the connection between the connecting pipe 6 and the hollow shaft 71. The rotary joint 61 is provided to prevent the rolling disk 7 and the hollow shaft 71 from affecting the connecting pipe 6 during rotation. A one-way valve housing 62 is provided at the connection between the connecting pipe 6 and the air supply pipe 5. A one-way valve plate 63 is slidably arranged in the inner cavity of the one-way valve housing 62. A compression spring 64 is provided on one side of the one-way valve plate 63. The inner diameter of the one-way valve housing 62, the diameter of the one-way valve plate 63, and the inner diameter of the connecting pipe 6 decrease in sequence, as Figure 10 shown. The gas in the inner cavity of the connecting pipe 6 can only flow unidirectionally. As Figure 8 shown, when the gas pressure in the inner cavity of the air supply pipe 5 is small, the one-way valve plate 63 inside the one-way valve housing 62 is not sufficient to open, and at this time, the gas in the inner cavity of the air supply pipe 5 cannot enter the inner cavity of the connecting pipe 6. By increasing the air pressure in the air supply pipe 5, the gas in the inner cavity of the air supply pipe 5 cannot be completely ejected from the nozzle 51, and the one-way valve plate 63 will be opened under the action of the air pressure. At this time, the gas in the inner cavity of the air supply pipe 5 can enter the inner cavity of the hollow shaft 71 through the connecting pipe 6.

[0027] To offset the weight of the rolling disk 7 itself, the present application further has a storage groove 73 opened on the side surface of the rolling disk 7. A guide post 74 is fixed at the bottom of the storage groove 73. An elastic tube 75 is arranged on the outer side of the guide post 74, and one end of the elastic tube 75 is fixedly connected to the bottom of the storage groove 73. The inner cavity of the elastic tube 75 is in communication with the hollow shaft 71. The other end of the elastic tube 75 is fixed with a sealing plate 76. A guide ring 77 is arranged on the surface of the sealing plate 76, and the guide ring 77 is movably sleeved on the outer side of the guide post 74, as Figure 8 and Figure 9 shown. The gas in the inner cavity of the hollow shaft 71 can enter the inner cavity of the elastic tube 75. When the air pressure in the air supply pipe 5 is large and part of the gas passes through the connecting pipe 6 and the hollow shaft 71 and enters the inner cavity of the elastic tube 75, the elastic tube 75 expands under the action of the air pressure. The volume of the elastic tube 75 increases and the buoyancy received by the water body increases, so as to offset the weight of the rolling disk 7 itself to a greater extent, making the resistance received by the rolling disk 7 smaller when it rolls.

[0028] To further prevent the rolling of the rolling disc 7 from being blocked, the present application also has a guide rail 78 arranged below the rolling disc 7. The guide rail 78 is circular and its center coincides with the mounting base 8. The rolling disc 7 rolls on the upper surface of the guide rail 78. Both the guide rail 78 and the mounting base 8 are fixedly embedded in the bottom of the breeding pond. As Figure 1 and Figure 2 shown, the rolling disc 7 only rolls on the upper surface of the guide rail 78. The width of the guide rail 78 itself is small, and it is difficult for waste materials to accumulate in large quantities on the upper surface of the guide rail 78, thereby avoiding the rolling of the rolling disc 7 being blocked due to a large amount of waste materials accumulating at the bottom of the breeding pond.

[0029] To supplement the description of the structure on the mounting base 8, the present application also has a vertically arranged inner pipe 81 fixedly installed on the upper part of the mounting base 8. An outer pipe 82 is fixedly sleeved on the outer side of the upper part of the inner pipe 81, and there is a gap between the outer pipe 82 and the inner pipe 81. A water pump 9 is arranged at the upper end of the inner pipe 81. The inner pipe 81 and the outer pipe 82 are respectively connected to the water inlet and the water outlet of the water pump 9. As Figure 1 and Figure 11 shown, when the water pump 9 is working, it is used to extract the water in the inner cavity of the outer pipe 82 and discharge the water into the inner cavity of the inner pipe 81. The mounting base 8, the inner pipe 81, the outer pipe 82 and the water pump 9 are fixedly connected and will not shift in position.

[0030] To respectively connect the water suction pipe 2 and the drain pipe 3 to the water inlet and the water outlet of the water pump 9, the present application also has outer sleeves 83 rotatably sleeved on the outer sides of the lower part of the inner pipe 81 and the outer side of the outer pipe 82. The two outer sleeves 83 are respectively fixedly connected to the ends of the water suction pipe 2 and the drain pipe 3. A plurality of evenly distributed connection holes 84 are formed on the surfaces of the inner pipe 81 and the outer pipe 82, and the outer sleeves 83 cover the outside of the connection holes 84. As Figure 11 shown, the water flow in the inner cavity of the inner pipe 81 can be exchanged with the drain pipe 3, and the water flow in the inner cavity of the outer pipe 82 can be exchanged with the water suction pipe 2. That is to say, when the water pump 9 is working, it can extract the water flow in the inner cavity of the water suction pipe 2, making the inner cavity of the water suction pipe 2 form a negative pressure, so that the water flow around the water suction pipe 2 can carry the waste materials and be sucked into the inner cavity of the water suction pipe 2 together. During the process of the water flow passing through the filter cylinder 1, the waste materials are separated from the water flow and enter the inner cavity of the hollow collection tray 14 for collection. Then the water pump 9 discharges the water flow into the inner cavity of the drain pipe 3 until it is discharged from the drain port 31 to form a cycle.

[0031] When the device is in use, the water pump 9 is started. The water pump 9 extracts the water at the bottom of the breeding pond through the water suction pipe 2 and discharges the extracted water into the inner cavity of the drain pipe 3 until it sprays out from the drain port 31. The water flow obliquely sprayed from the drain port 31 impacts the waste materials at the bottom of the breeding pond, causing the waste materials to be stirred up and suspended in the water body, so as to be sucked into the inner cavity of the water suction pipe 2 through the water suction port 22; When the water flows in the inner cavities of the water suction pipe 2 and the drain pipe 3, it impacts the upper half of the second impeller 43 and the lower half of the first impeller 42 respectively, enabling the first impeller 42 and the second impeller 43 to rotate in the same direction. The water body in the inner cavity of the water suction pipe 2 carries waste into the inner cavity of the filter cylinder 1. The curved surface filter screen 21 can filter and separate the waste, leaving the waste in the inner cavity of the filter cylinder 1. At this time, the second impeller 43 rotates and moves the waste from the upper half of the inner cavity of the filter cylinder 1 to the lower half. When the waste moves to the slag discharge port 12, the inclined second impeller 43 pushes the water flow to carry the waste out of the slag discharge port 12 together until it enters the inner cavity of the hollow collection tray 14 for collection.

[0032] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
