[0002] During the shrimp larvae farming process, organic waste such as uneaten feed, feces, and algae residues accumulate in the ponds and form silt at the bottom. If this waste is not cleaned up in time, it will decompose and produce harmful substances such as ammonia nitrogen and nitrite, leading to water quality deterioration and increasing the risk of disease in the shrimp larvae.

[0019] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit 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.

[0020] Please see Figures 1 to 11 The present invention provides a technical solution: Example 1: A waste cleaning device for shrimp larvae farming, comprising: a mounting base 8.

[0021] Specifically, a filter cylinder 1 is mounted on the outer side of the mounting base 8 and rotates around it. The filter cylinder 1 is suspended and does not contact the bottom of the aquaculture pond. A fixing cylinder 11 is fixedly installed through the middle of the filter cylinder 1, and both ends of the fixing cylinder 11 are connected to the outer side of the filter cylinder 1. A mounting collar 4 is movably fitted on the outer side of the fixing cylinder 11. The mounting collar 4 can rotate around the fixing cylinder 11 inside the filter cylinder 1. An annular partition 41 is fixedly connected to the middle of the mounting collar 4, and the annular partition 41 divides the inner cavity of the filter cylinder 1 into two compartments. Fan blade 1 42 and fan blade 2 43 are fixed on the two sides of the annular partition 41, respectively. Figure 4 As shown, after the inner cavities of the compartments on the left and right sides of the filter cylinder 1 are separated by the annular partition 41, the water flow inside the two compartments will not be exchanged. Secondly, a water suction pipe 2 and a water drain pipe 3 are fixedly connected to the outside of the filter cylinder 1, and both the water suction pipe 2 and the water drain pipe 3 are tangent to the filter cylinder 1. The water suction pipe 2 and the water drain pipe 3 are located in the upper and lower halves of the filter cylinder 1, respectively, and are connected to two compartments inside the filter cylinder 1. The water flow directions inside the water suction pipe 2 and the water drain pipe 3 are opposite, but since they are located in the upper and lower halves of the filter cylinder 1, the fan blades 42 and 43 rotate in the same direction when impacted by the water flow. A curved filter screen 21 is installed in the inner cavity of one end of the water suction pipe 2, and a water suction port 22 is installed on the surface of the water suction pipe 2. A water drain port 31 is installed on the surface of the water drain pipe 3, and the water drain port 31 is inclined downward. The water suction pipe 2 is mainly used for the bottom of the aquaculture pond. The water is absorbed, allowing the waste in the water to flow with the water flow. The curved filter screen 21 is set 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 outlet 31 and sprayed onto the bottom of the breeding pond. This is used 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 suction pipe 2. Since the drain outlet 31 is inclined downward, when the water flow is sprayed from the drain outlet 31, the reaction force generated by the water flow on the drain pipe 3 can, on the one hand, push the drain pipe 3 and the suction pipe 2 to move as a whole (i.e., rotate around the mounting base 8), and on the other hand, it can also generate a certain lifting force on the drain pipe 3 and the suction pipe 2 as a whole, so as to prevent the drain pipe 3 and the suction pipe 2 from falling and getting stuck at the bottom of the breeding pond.

[0022] To further explain the first fan blade 42 and the second fan blade 43, the suction pipe 2 of this application corresponds to the second fan blade 43, which is inclined. When the water flows inside the suction pipe 2, it impacts the surface of the second fan blade 43, causing it to rotate. The drain pipe 3 corresponds to the first fan blade 42, which is parallel to the axis of the mounting ring 4. One end of the surface of the mounting ring 4 has a pressure-stabilizing hole 44, which is spaced apart from the second fan blade 43. One end of the surface of the fixing cylinder 11 has a notch 111, which is located in the lower half of the fixing cylinder 11. Figure 5 and Figure 6 As shown, the pressure stabilizing hole 44 and the notch 111 are mainly used to maintain the water pressure stability in the inner cavity of one side of the filter cylinder 1. Due to the tilt of the fan blade 43 itself, when the fan blade 43 rotates, it will push the water body to have a tendency to move away from the annular baffle 41.

[0023] To discharge waste material from the inner cavity of the filter cylinder 1, the curved filter screen 21 of this application is located at a connection point between the water suction pipe 2 and the filter cylinder 1. The curved filter screen 21 is flush with the inner wall of the filter cylinder 1. After the curved filter screen 21 filters and separates the waste material from the inner cavity of the filter cylinder 1, the edge of the fan blade 43 can scrape off the waste material on the surface of the curved filter screen 21 when it rotates, allowing the waste material to rotate and move together with the fan blade 43. A slag discharge port 12 is provided on the lower half of one side of the filter cylinder 1, and the slag discharge port 12 corresponds to the fan blade 43. Figure 4 , Figure 5 and Figure 6 As shown, the pressure-stabilizing hole 44 at the upper half of the mounting collar 4 is blocked by the fixing cylinder 11. At this time, the water flow inside the fixing cylinder 11 will not enter the inner cavity of the filter cylinder 1. However, after the pressure-stabilizing hole 44 at the lower half of the mounting collar 4 corresponds to the notch 111, the water flow inside the fixing cylinder 11 can pass through the notch 111 and the pressure-stabilizing hole 44 in sequence and enter the inner cavity of the filter cylinder 1. As mentioned above, due to the inclination of the fan blade 43, when the fan blade 43 rotates, it will push the water body away from the annular baffle 41. Therefore, the water body located in the lower half of the inner cavity on one side of the filter cylinder 1 will be discharged from the slag discharge port 12 under the thrust of the fan blade 43, so that the water flow can carry the slag. Waste material is discharged from the inner cavity of the filter cylinder 1. A magnet 13 is fixed on one side of the filter cylinder 1. A hollow collection plate 14 is provided on the outer side of the filter cylinder 1. The hollow collection plate 14 is attracted to the magnet 13 and the inner cavity of the hollow collection plate 14 is connected to the slag discharge port 12. A filter plate 15 is movably inserted from top to bottom in the middle of the inner cavity of the hollow collection plate 14. The hollow collection plate 14 is set up to collect waste material. The filter plate 15 in the inner cavity of the hollow collection plate 14 can be used to filter and separate waste material and water flow. The water flow can flow into the aquaculture pond, while the waste material remains in the inner cavity of the hollow collection plate 14. After the device has been used for a long time, the hollow collection plate 14 can be removed periodically and the waste material can be cleaned.

[0024] To supply oxygen to the water in the aquaculture pond, the water intake 22 of this application is set on both sides of the surface of the water intake pipe 2. The water intake 22 is a flat shape with an outward opening. The large opening of the water intake 22 facilitates the extraction of waste. The drain outlet 31 is located on the side of the drain pipe 3 close to the water intake pipe 2. The drain outlet 31 is a flat shape with a narrow opening. The narrow opening structure of the drain outlet 31 makes the sprayed water flow faster, which can improve the impact effect on the waste at the bottom of the aquaculture pond and prevent the accumulation of waste. An air supply pipe 5 is fixedly installed on the outside of the drain pipe 3. The surface of the air supply pipe 5 is provided with multiple nozzles 51 distributed at equal intervals. The air supply pipe 5 is mainly used to supply oxygen to the water in the aquaculture pond. Since the air supply pipe 5 itself is a hollow structure, the buoyancy generated by the water on the air supply pipe 5 can offset the overall weight of the drain pipe 3 and the water intake pipe 2 to a certain extent.

[0025] To support the water suction pipe 2 and the drain pipe 3 as a whole, this application also includes a rolling disc 7 on the outer side of the other end of the water suction pipe 2. A hollow shaft 71 is fixedly installed through the middle of the rolling disc 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 fixedly connected to the water suction pipe 2 and the drain pipe 3, respectively. The hollow shaft 71 and the air supply pipe 5 are kept in communication through a connecting pipe 6. The rolling disc 7 is mainly used to support the water suction pipe 2 and the drain pipe 3 as a whole, so that the rolling disc 7 can roll at the bottom of the aquaculture pond when the water suction pipe 2 and the drain pipe 3 rotate and move around the mounting base 8.

[0026] To prevent gas from easily entering the inner cavity of the connecting pipe 6 from the inner cavity of the air supply pipe 5, this application also includes a rotary connector 61 at the connection between the connecting pipe 6 and the hollow shaft 71. The rotary connector 61 is provided to prevent the rotating 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 sequentially. Figure 10 As shown, the gas inside the connecting pipe 6 can only flow in one direction. Figure 8 As shown, when the gas pressure inside the air supply pipe 5 is low, the one-way valve plate 63 inside the one-way valve housing 62 is insufficient to open. At this time, the gas inside the air supply pipe 5 cannot enter the inner cavity of the connecting pipe 6. By increasing the gas pressure inside the air supply pipe 5, the gas inside the air supply pipe 5 cannot be completely ejected from the nozzle 51. The one-way valve plate 63 will be opened under the action of gas pressure. At this time, the gas inside the air supply pipe 5 can enter the inner cavity of the hollow shaft 71 through the connecting pipe 6.

[0027] To counteract the weight of the rolling disk 7 itself, this application also includes a storage groove 73 on the side of the rolling disk 7. A guide post 74 is fixed to the bottom of the storage groove 73. An elastic tube 75 is provided on the outside 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 communicates with the hollow shaft 71. A sealing plate 76 is fixed to the other end of the elastic tube 75. A guide ring 77 is provided on the surface of the sealing plate 76, and the guide ring 77 is movably sleeved on the outside of the guide post 74. Figure 8 and Figure 9 As shown, the gas inside the hollow shaft 71 can enter the inner cavity of the elastic tube 75. When the air pressure inside the air supply pipe 5 is relatively high, and some gas passes through the connecting pipe 6 and the hollow shaft 71 into the inner cavity of the elastic tube 75, the elastic tube 75 expands under the action of air pressure. The volume of the elastic tube 75 increases and the buoyancy of the water increases, which can offset the weight of the rolling disk 7 to a greater extent, so that the rolling disk 7 experiences less resistance when it rolls.

[0028] To further prevent the rolling disk 7 from being obstructed, this application also includes a guide rail 78 provided below the rolling disk 7. The guide rail 78 is circular, and its center coincides with the mounting base 8. The rolling disk 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 aquaculture pond. Figure 1 and Figure 2 As shown, the rolling disk 7 only rolls on the upper surface of the guide rail 78. The guide rail 78 itself is relatively narrow, making it difficult for waste to accumulate in large quantities on the upper surface of the guide rail 78. This avoids the rolling disk 7 from being obstructed due to the accumulation of a large amount of waste at the bottom of the aquaculture pond.

[0029] To further illustrate the structure of the mounting base 8, this application also includes a vertically arranged inner tube 81 fixedly installed on the upper part of the mounting base 8. An outer tube 82 is fixedly sleeved on the upper outer side of the inner tube 81, with a gap between the outer tube 82 and the inner tube 81. A water pump 9 is installed at the upper end of the inner tube 81. The inner tube 81 and the outer tube 82 are respectively connected to the inlet and outlet of the water pump 9. Figure 1 and Figure 11 As shown, when the water pump 9 is working, it is used to extract water from 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 connect the suction pipe 2 and the drain pipe 3 to the inlet and outlet of the water pump 9, respectively, this application further includes an outer sleeve 83 rotatably fitted on both the lower outer side of the inner pipe 81 and the outer side of the outer pipe 82. The two outer sleeves 83 are fixedly connected to the ends of the suction pipe 2 and the drain pipe 3, respectively. Multiple evenly distributed connection holes 84 are formed on the surfaces of both the inner pipe 81 and the outer pipe 82, and the outer sleeves 83 cover the outside of the connection holes 84. Figure 11 As 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 suction pipe 2. That is to say, when the water pump 9 is working, it can draw water from the inner cavity of the suction pipe 2, so that the inner cavity of the suction pipe 2 forms a negative pressure, thereby allowing the water flow around the suction pipe 2 to carry the waste material into the inner cavity of the suction pipe 2. During the process of the water flow passing through the filter cylinder 1, the waste material is separated from the water flow and enters the inner cavity of the hollow collection tray 14 for collection. Then the water pump 9 discharges the water flow back into the inner cavity of the drain pipe 3 until it is discharged from the drain outlet 31, forming a cycle.

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

[0032] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
