Description

Technical Field

[0001] This utility model relates to the field of shrimp larvae farming technology, specifically to a shrimp larvae breeding pond with a circulating water purification function. Background Technology

[0002] The giant freshwater prawn (Macrobrachium rosenbergii) is an animal belonging to the family Palaemonidae and the genus Macrobrachium. It is large in size, with the largest male individuals reaching a length of 400 mm. After one year of cultivation, it typically reaches a length of 150-200 mm. There are two types of giant freshwater prawn larvae: one is a freshwater-acclimated larva with a body length of less than 1 cm, and the other is a freshwater-acclimated larva that has been raised to about 3 cm in length. Because the freshwater-acclimated larvae are delicate and have weak resistance to diseases and the external environment, it is necessary to raise these larvae first to improve the survival rate after release.

[0003] In current shrimp larvae rearing ponds, the larvae defecate after feeding, which affects the water quality and requires frequent water changes. In large-scale farming, water changes are very inconvenient and wasteful, making the ponds unsuitable for use. Furthermore, existing rearing ponds are not convenient for oxygenation, and when dissolved oxygen in the water is insufficient, the shrimp larvae will experience breathing difficulties.

[0004] Therefore, it is necessary to provide a breeding pond for giant freshwater prawns that includes a circulating water purification function. Utility Model Content

[0005] The purpose of this invention is to provide a giant freshwater prawn breeding pond with a circulating water purification function, in order to solve the problems mentioned in the background art, such as the prawns defecating after feeding, which affects the water quality in the breeding pond, requiring frequent water changes, which is very inconvenient and wasteful in large-scale farming, and is also inconvenient to use. Furthermore, existing breeding ponds are not convenient for oxygenation, and when the dissolved oxygen in the water is insufficient, the prawns will have difficulty breathing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a giant freshwater prawn breeding pond with a circulating water purification function, comprising a breeding pond body, mounting frames fixedly installed at both ends of the top surface of the breeding pond body, a baffle assembly fixedly installed between the two mounting frames, a filter assembly for purifying water fixedly connected to one side of the breeding pond body, a circulation assembly for circulating water fixedly connected between the breeding pond body and the filter assembly, and an oxygenation assembly sleeved on one end of the circulation assembly.

[0007] Preferably, the enclosure assembly includes two connecting rods, each fixedly installed at one end of one of two mounting brackets. A telescopic rod is fixedly installed between both ends of the two connecting rods. A safety net is fixedly connected to the bottom of the connecting rods and the telescopic rods. Counterweights are fixedly installed at the four corners of the bottom of the safety net. 可以 By concentrating shrimp larvae in a specific area, it becomes easier for farmers to perform unified feeding, observation, and disease monitoring.

[0008] Preferably, the filtration assembly includes a filtration tank. Inside the filtration tank, a baffle and two flow plates are installed at equal intervals. The interior of the filtration tank is divided into a wastewater discharge area, a first filtration area, a second filtration area, and a third filtration area by the baffle and the two flow plates. Each of the first, second, and third filtration areas is equipped with a mesh screen. The top surface of the mesh screen in the first filtration area is fitted with coarse-pore filter cotton. The top surface of the mesh screen in the second filtration area is fitted with multiple filter brushes. The top of the mesh screen in the third filtration area is fitted with fine-pore filter cotton. This effectively removes suspended particles, organic residues, algae, and other impurities from the water, keeping the water clear and transparent, improving the water's transparency and aesthetics, providing a clean living environment for the giant freshwater prawn larvae, and ensuring their survival and growth.

[0009] Preferably, one side of the sewage discharge area is connected to a forced discharge port, and three sewage discharge pipes are installed inside the sewage discharge area. One end of each of the three sewage discharge pipes extends into the interior of the first filtration area, the second filtration area, and the third filtration area, respectively. The other end of each of the three sewage discharge pipes is connected to a connector. By regularly discharging sewage, these accumulated pollutants can be removed, keeping the filter media clean and the pores unobstructed, ensuring that the filter pool always maintains a good filtration effect and continuously and effectively removes harmful substances from the water.

[0010] Preferably, the circulation component includes a pumping pipe and a connecting pipe. The pumping pipe is connected to one side of the seedling tank body, and the other end of the pumping pipe extends into the interior of the first filtration zone. A second water pump is connected to the middle of the pumping pipe. The connecting pipe is fixedly connected to one side of the filtration tank, and one end of the connecting pipe is fixedly connected to a first water pump. The outlet of the first water pump is fixedly connected to a return water pipe, and one end of the return water pipe extends into the interior of the seedling tank body. This allows for the recycling of treated water, requiring only the replenishment of a small amount of water lost due to evaporation, leakage, etc., greatly reducing the demand for fresh water and lowering aquaculture costs.

[0011] Preferably, the oxygenation component includes an oxygen supply pipe, which is fixedly connected to one end of the return water pipe. A circular groove is provided at the top of the oxygen supply pipe, and an air inlet pipe is fixedly installed inside the circular groove. In an oxygen-rich environment, the shrimp larvae's feeding, digestion, and absorption capabilities are enhanced, enabling them to more effectively ingest and utilize nutrients in the feed, thereby accelerating their growth and shortening the seedling cycle.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] Please see Figure 1-4 This utility model provides a giant freshwater prawn breeding pond with a circulating water purification function, including a breeding pond body 1. Both ends of the top surface of the breeding pond body 1 are fixedly installed with mounting frames 2. A baffle assembly is fixedly installed between the two mounting frames 2. A filter assembly for purifying water is fixedly connected to one side of the breeding pond body 1. A circulation assembly for circulating water is fixedly connected between the breeding pond body 1 and the filter assembly. An oxygenation assembly is sleeved on one end of the circulation assembly.

[0020] Furthermore, the enclosure assembly includes two connecting rods 3, which are respectively fixedly installed at one end of two mounting frames 2. Telescopic rods 4 are fixedly installed between the two ends of the two connecting rods 3. An isolation net 5 is fixedly connected to the bottom between the connecting rods 3 and the telescopic rods 4. Counterweights 6 are fixedly installed at the four corners of the bottom of the isolation net 5. Pulling the two connecting rods 3 will open the bottom isolation net 5 through the telescopic rods 4. The isolation net 5 is then installed into the inside of the seedling pond body 1 through the mounting frames 2, and shrimp larvae are placed inside for seedling cultivation.

[0021] Furthermore, the filtration assembly includes a filter tank 8. Inside the filter tank 8, a baffle 9 and two flow plates 10 are installed at equal intervals. The interior of the filter tank 8 is divided into a wastewater discharge zone 11, a first filtration zone 12, a second filtration zone 13, and a third filtration zone 14 by the baffle 9 and the two flow plates 10. Each of the first filtration zone 12, second filtration zone 13, and third filtration zone 14 is equipped with a filter screen 15. In the first filtration zone 12, a coarse-pore filter cotton 16 is installed on the top surface of the filter screen 15. In the second filtration zone 13, multiple filter brushes 17 are installed on the top surface of the filter screen 15. In the third filtration zone... The top of the storage mesh plate 15 inside the filter zone 14 is equipped with fine-pore filter cotton 18. When the water in the nursery pond 1 enters the first filter zone 12 through the water pumping pipe 7, it undergoes the first layer of filtration through the coarse-pore filter cotton 16, blocking large-volume debris. Then, it enters the second filter zone 13 through a diverter plate 10, undergoes the second layer of filtration through the filter brush 17, blocking fish feces and other impurities. Then, it enters the third filter zone 14 through another diverter plate 10, undergoes the third layer of filtration through the fine-pore filter cotton 18, filtering out small stones, gravel, and other impurities before flowing out through the connecting pipe 22.

[0022] Furthermore, a forced discharge port 21 is connected to one side of the sewage discharge area 11. Three sewage pipes 19 are installed inside the sewage discharge area 11. One end of each sewage pipe 19 extends into the first filtration area 12, the second filtration area 13, and the third filtration area 14, respectively. The other end of each sewage pipe 19 is connected to a connector 20. After long-term filtration, the filter tank 8 needs to be cleaned. Because of the connector 20, the water in the three sewage pipes 19 will not flow into the sewage pipes 19. By pulling out the connector 20, the water level at one end of the sewage pipe 19 in the sewage discharge area 11 will be lower than the water level at the other end of the three filtration areas. This allows the sewage from the first filtration area 12, the second filtration area 13, and the third filtration area 14 to flow into the sewage discharge area 11. After the sewage in the sewage discharge area 11 is discharged through the forced discharge port 21, the connector 20 is inserted back to resume filtration.

[0023] Furthermore, the circulation component includes a pumping pipe 7 and a connecting pipe 22. The pumping pipe 7 is connected to one side of the seedling tank body 1, and the other end of the pumping pipe 7 extends into the interior of the first filtration zone 12. The middle of the pumping pipe 7 is connected to a second water pump 27. The connecting pipe 22 is fixedly connected to one side of the filtration tank 8. One end of the connecting pipe 22 is fixedly connected to a first water pump 23. The outlet end of the first water pump 23 is fixedly connected to a return water pipe 24. One end of the return water pipe 24 extends into the interior of the seedling tank body 1. The first water pump 23 and the second water pump 27 are connected to an external power source. The second water pump 27 is started to pump water from inside the seedling tank body 1 into the filtration tank 8 through the pumping pipe 7. After filtration, the water flows into the connecting pipe 22. The connecting pipe 22 is connected to the return water pipe 24 through the first water pump 23, and the filtered water is sent back to the seedling tank body 1.

[0024] Furthermore, the oxygenation component includes an oxygen supply pipe 25, which is fixedly connected to one end of the return water pipe 24. A circular groove is opened at the top of the oxygen supply pipe 25, and an air inlet pipe 26 is fixedly installed inside the circular groove. Oxygen bubbles are introduced into the oxygen supply pipe 25 through the air inlet pipe 26. When the filtered water returns to the seedling tank body 1 through the return water pipe 24, the thrust of the water flow will disperse the oxygen bubbles and supply oxygen to the water in the seedling tank body 1.

[0025] In this embodiment, the following steps are taken: Pull the two connecting rods 3 to open the bottom isolation net 5 via the telescopic rod 4. Install the isolation net 5 into the inside of the nursery pond body 1 via the mounting bracket 2. Place shrimp larvae into the pond for larval rearing. Connect the first water pump 23 and the second water pump 27 to an external power source. Start the second water pump 27 to pump water from the nursery pond body 1 into the filter tank 8 via the pumping pipe 7. After the water from the nursery pond body 1 enters the first filter zone 12 through the pumping pipe 7, it undergoes the first layer of filtration through the coarse-pore filter cotton 16, blocking large-volume debris. Then, it passes through a diverter plate 10 into the second filter zone 13, undergoes the second layer of filtration through the filter brush 17, blocking fish feces and other impurities. Then, it passes through another diverter plate 10 into the third filter zone 14, undergoes the third layer of filtration through the fine-pore filter cotton 18, filtering out small stones, gravel, and other impurities. The filtered water then flows out through the connecting pipe 22, which is connected to the return water pipe 24 via the first water pump 23, returning the filtered water to the nursery pond. The main body 1 introduces oxygen bubbles into the oxygen supply pipe 25 through the air inlet pipe 26. When the filtered water returns to the main body 1 of the seedling pond through the return water pipe 24, the thrust of the water flow will disperse the oxygen bubbles and supply oxygen to the water in the main body 1 of the seedling pond. After long-term filtration, the filter tank 8 needs to be cleaned. Because of the presence of the insertion pipe 20, the water in the three sewage pipes 19 will not flow into the sewage pipe 19. By pulling out the insertion pipe 20, the water level at one end of the sewage pipe 19 in the sewage discharge area 11 will be lower than the water level at the other end of the three filtration areas. The sewage from the first filtration area 12, the second filtration area 13 and the third filtration area 14 can flow into the sewage discharge area 11. After the sewage in the sewage discharge area 11 is discharged through the strong discharge port 21, the insertion pipe 20 is inserted back to restore the filtration work. When it is necessary to transfer or scoop the shrimp seedlings, the connection between the connecting rod 3 and the mounting frame 2 can be disassembled. The telescopic rod 4 is brought close to the two connecting rods 3, and then the shrimp seedlings inside can be scooped out through the isolation net 5.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
