[0002] Urban agricultural product cultivation and fishery farming are set up separately. In addition to consuming a lot of water resources, the discharge of wastewater will also cause environmental pollution. Therefore, proper system integration allows the water supply to be recycled between agricultural product cultivation and fishery farming, thus deriving a fish-vegetable symbiotic system.

[0003] The operating principle of the so-called aquaponics system is to utilize the interaction between organisms in nature to operate. It is an ecosystem basically composed of plants, fish, bacteria or microorganisms to convert fish excrement into plant nutrients. In fact, the wastewater from farmed fish is used to produce nutrients needed for plant growth through bacterial nitrification. The wastewater is eventually purified into clean water. Therefore, the entire aquaponics system is a closed water circulation system, which has the advantages of no need to change water for farming and no need to water for growing vegetables. At the same time, it is an organic breeding and farming technology that can provide humans with more natural and healthier food.

[0004] Traditional fish-vegetable symbiosis mostly uses multi-layer frames, but in this fish-vegetable symbiosis model, the planting boards of the upper frames block the seedlings planted in the lower frames, and it is inevitable that the seedlings planted in the lower layers will not receive sufficient light.

[0027] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides a fish-vegetable symbiotic system, which includes: a fish pond 1, a purification part and a planting part;

[0028] The purification unit includes a support column 2, a clean water pool 3 and a water pipe 4. The clean water pool 3, the support column 2 and the fish pond 1 are connected in sequence from top to bottom. The inlet end of the water pipe 4 is located in the fish pond 1, and the outlet end of the water pipe 4 passes through the bottom wall of the clean water pool 3.

[0029] The planting part includes a plurality of stepped tubes 6, which are evenly distributed around the water purification pool 3, the upper end of the stepped tubes 6 is connected to the side wall of the water purification pool 3, the lower end of the stepped tubes 6 is located within the range of the fish pond 1, and the tube wall of the stepped tube 6 has a plurality of first planting holes 7 arranged axially.

[0030] The working process of an aquaponics system is as follows:

[0031] First, the seedlings are planted in the multiple first planting holes 7 respectively, and then the booster pump 5 is started. The water in the fish pond 1 is transported upward to the clean water tank 3 through the water pipe 4, and the water in the clean water tank 3 flows downward back to the fish pond 1 along the multiple stepped pipes 6. In the above process, the water flowing in the stepped pipes 6 infiltrates the roots of the planted seedlings. The vertical pipe sections and horizontal pipe sections of the stepped pipes 6 are respectively provided with multiple first planting holes 7. The seedlings are planted, which makes full use of the space between the clean water tank 3 and the fish pond 1. Moreover, there are no objects blocking the periphery of the stepped pipes 6, and the seedlings in the multiple first planting holes 7 can fully receive light.

[0032] In the technical solution of the present utility model, a plurality of stepped tubes 6 are distributed around the circumference, and the roots of the planted seedlings therein are continuously infiltrated by water flow, and the leaves of the planted seedlings can fully receive light.

[0033] Specifically, it also includes a booster pump 5 , which is a submersible pump. The outlet of the booster pump 5 is connected to the inlet end of the water pipe 4 , and the water pipe 4 is coaxially arranged in the support column 2 .

[0034] Specifically, a control valve 8 is installed at the upper port of the stepped pipe 6 for controlling the water inlet flow of the stepped pipe 6 so that the radial cross-section of the water flow only occupies a semicircle of the radial cross-section of the stepped pipe 6 at most, thereby preventing the stepped pipe 6 from being filled with water, thereby preventing the first planting hole 7 from overflowing with water.

[0035] Specifically, the lower end side of the fish pond 1 is connected to a drain pipe 9 , and a drain valve 10 is installed on the drain pipe 9 .

[0036] like Figure 1 and Figure 2 As shown, in a specific embodiment, a cylinder 11 is provided in the water purification tank 3, which is used to separate the water purification tank 3 into a central sedimentation tank and a peripheral nitrification tank, and the outlet end of the water supply pipe 4 passes through the bottom wall of the central sedimentation tank, and a filter layer 1103 is provided in the central sedimentation tank.

[0037] In this embodiment, specifically, the water in the fish pond 1 enters the central sedimentation tank through the water pipe 4, and the large particles of impurities in the water are intercepted by the filter layer 1103 and settled at the bottom of the central sedimentation tank. The water after impurities are removed overflows the upper edge of the central sedimentation tank and enters the peripheral nitrification tank. After nitrification, the ammonia ions in the water are oxidized into nitrates, thereby purifying the water. The purified water enters a plurality of stepped pipes 6, ensuring that the water in the fish-vegetable symbiotic system can circulate for a long period of time and maintain the long-term cultivation of planted seedlings.

[0038] Specifically, biochemical balls are arranged in the peripheral nitrification pool, and nitrifying bacteria can reproduce and grow on the surface of the biochemical balls.

[0039] like Figure 1 , Figure 2 and Figure 3 As shown, in a specific embodiment, a plurality of venturi tubes 12 are further included, the inlet of each venturi tube 12 is connected to the side wall of the clean water pool 3 , and the outlet of each venturi tube 12 is connected to the upper port of one of the stepped tubes 6 .

[0040] In this embodiment, specifically, each venturi tube 12 includes a sleeve 1201 and a tapered tube 1202, the tapered tube 1202 is coaxially arranged in the sleeve 1201, the small end of the tapered tube 1202 is close to the outlet of the sleeve 1201, the large end of the tapered tube 1202 is close to the inlet of the sleeve 1201, the inlet of the sleeve 1201 is connected to the side wall of the clean water pool 3, the outlet of the sleeve 1201 is connected to the upper port of the stepped tube 6, and the side wall of the sleeve 1201 at the small end of the tapered tube 1202 is connected to the air intake pipe 1203.

[0041] During the operation of this system, the water after nitrification flows through the conical tube 1202, and a negative pressure area (Venturi effect) is formed outside the small end of the conical tube 1202, so that the outside air enters the sleeve 1201 through the air inlet pipe 1203, thereby increasing the oxygen content in the water. The oxygenated water enters the stepped tube 6 to provide nutrients for the roots of the planted seedlings.

[0042] like Figure 1 As shown, in a specific embodiment, the cylinder 11 includes a first cylinder 1101 and a second cylinder 1102, the lower end of the first cylinder 1101 is fixedly connected to the bottom wall of the water purification pool 3, the lower end of the second cylinder 1102 is threadedly connected to the upper end of the first cylinder 1101, and the edge of the filter layer 1103 is fixedly connected to the inner wall of the second cylinder 1102.

[0043] In this embodiment, specifically, after a batch of planted seedlings are harvested, the booster pump 5 is stopped, and then the second cylinder 1102 is rotated away from the upper end of the first cylinder 1101 to clean the impurities in the central sedimentation tank. At the same time, the filter layer 1103 in the second cylinder 1102 can also be cleaned, thereby ensuring the cleanliness of the system water environment when the next batch of seedlings are planted.

[0044] like Figure 1 As shown, in a specific implementation, the outlet end of the water pipe 4 is flush with the upper end of the first cylinder 1101 .

[0045] In this embodiment, the outlet end of the water pipe 4 is flush with the upper end of the first cylinder 1101, and there is a height difference between the outlet pipe of the water pipe 4 and the bottom wall of the central sedimentation tank. After the impurities entering the central sedimentation tank are settled, it is not easy to flow back into the water pipe 4 again, which is convenient for centralized cleaning of impurities in the central sedimentation tank at a later time.

[0046] like Figure 1 and Figure 2 As shown, in a specific embodiment, the planting part also includes a plurality of straight tubes 13, one end of each of the straight tubes 13 is connected to the lower port of one of the stepped tubes 6, the other end of each of the straight tubes 13 is close to the supporting column 2, and the upper side wall of each of the straight tubes 13 is axially arranged with a plurality of second planting holes 15.

[0047] In this embodiment, specifically, a plurality of mounting seats 14 are provided at the upper edge of the fish pond 1 , and each straight tube 13 is correspondingly snapped into one of the mounting seats 14 , and the straight tube 13 is horizontally arranged below the stepped tube 6 .

[0048] Specifically, this planting structure can meet the needs of planting vegetables of different plant heights at the same time. The second planting holes 15 on the upper side wall of the straight tube 13 can be used to plant vegetable seedlings with higher plant heights and that prefer shade, and the first planting holes 7 can be used to plant vegetable seedlings that prefer sun.

[0049] Specifically, the peripheral side walls of the purification tank are fixedly connected to a plurality of support rod clamps for fixing the planted fruit and vegetables or branches and leaves of vine plants.

[0050] like Figure 1 and Figure 2 As shown, in a specific embodiment, a plurality of the first planting holes 7 are located on a side wall of the stepped tube 6 away from the fish pond 1 .

[0051] In this embodiment, specifically, the plurality of first planting holes 7 are respectively oriented toward the periphery of the system to facilitate receiving external light.

[0052] In a specific embodiment, the outlet of the venturi tube 12 is threadedly connected to the upper port of the stepped tube 6 .

[0053] In this embodiment, specifically, the side wall of the purification tank, the control valve 8 , the venturi tube 12 and the stepped tube 6 are connected in sequence, wherein the outlet of the venturi tube 12 is threadedly connected to the stepped tube 6 .

[0054] With this setting, the effect is as follows:

[0055] Sometimes, only a part of the stepped tubes 6 are needed for planting seedlings in the same batch. At this time, the operator can disassemble the idle stepped tubes 6 and close the control valve 8 of the corresponding venturi tube 12 to prevent the venturi tube 12 from leaking.

[0056] Specifically, the outlet of the venturi tube 12 is rotatably connected to one end of the hexagonal nut 17 (the outlet end of the venturi tube 12 is coaxially fixedly connected to the first annular baffle 18, the first annular baffle 18 is located inside the hexagonal nut 17, one end of the hexagonal nut 17 is coaxially fixedly connected to the second annular baffle 19, the second annular baffle 19 and the first annular baffle 18 are mutually abutted to prevent the hexagonal nut 17 from detaching from the venturi tube 12), the internal thread of the other end of the hexagonal nut 17 is screwed into the external thread of the upper port of the stepped tube 6, and the upper port of the stepped tube 6 is pressed against the sealing rubber ring on the surface of the first annular baffle 18.

[0057] like Figure 1 and Figure 2 As shown, in a specific embodiment, it also includes a plurality of overflow pipes 16 , and the plurality of overflow pipes 16 are respectively connected to the upper end side of the second cylinder 1102 .

[0058] In this embodiment, specifically, a plurality of overflow pipes 16 are circumferentially distributed around the upper end of the second cylinder 1102, and the water after impurities are removed can flow synchronously to the peripheral nitrification tank through the plurality of overflow pipes 16, so that nitrification in different areas of the peripheral nitrification tank proceeds synchronously.

[0059] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
