[0002] Fish-vegetable co-culture, also known as fish-vegetable symbiosis, is a new type of composite farming system that combines two completely different technologies, aquaculture and hydroponics, through a clever ecological design to achieve scientific symbiotic coexistence. This technology adopts the concept of "solving ecological problems ecologically", combines the biochemical system and the planting system, and utilizes the characteristics of mineral nutrient storage, degradation, and slow release to optimize the self-regulating function of the system, keep the nutrient balance of the system, and truly achieve "raising fish without changing water and growing vegetables without fertilizing".

[0003] Traditional aquaculture ponds often use bottom drainage of fish toilets and an external overflow pipe to control the water level of the aquaculture pond. The fish feces and sewage deposited at the bottom of the aquaculture pond are discharged through the bottom fish toilet. However, there is also suspended sewage with a relatively small density in the middle of the aquaculture pond, and this suspended sewage cannot be effectively discharged through the fish toilet. If it remains for a long time, it will cause the water body to be turbid, and the ammonia nitrogen and nitrite indexes will exceed the standard, which is not conducive to the normal growth of fish.

[0004] Therefore, it is necessary to develop a drainage device for a fish-vegetable co-culture aquaculture pond to address the above-mentioned defects. Summary of the Utility Model

[0023] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0024] In a specific embodiment, as Figure 1 and Figure 2 shown, the drainage device for the fish-vegetable co-culture aquaculture pond of the present utility model is applied to the drainage of the aquaculture pond 7, and includes a drainage shield pipe 1, a filter element 2, a central pipe 3, a drain pipe 4 and a plug 5. The drain pipe 4 for returning water to the vegetable planting bed is horizontally arranged below the aquaculture pond 7, and the drain pipe 4 is not provided with a drainage slope. The bottom end of the vertically arranged central pipe 3 is communicated with the drain pipe 5, and the top end of the central pipe 3 extends into the aquaculture pond 7. The drainage shield pipe 1 is arranged in the aquaculture pond 7 and vertically coaxially covers the outside of the central pipe 3, and the bottom end of the drainage shield pipe 1 is connected to the bottom wall of the aquaculture pond 7 through the filter element 2. It should be noted that the filter element 2 is specifically a filter mesh sheet with a relatively large mesh diameter, so that fish feces can pass through, but larger sundries cannot pass through, preventing blockage of the drainage pipeline. A plurality of water permeable holes 101 are uniformly arranged on the middle side wall of the drainage shield pipe 1, and the plurality of water permeable holes 101 are circumferentially arranged. The plug 5 is detachably plugged on the top opening of the drainage shield pipe 1, and the plug 5 is a rubber plug.

[0025] By providing a filter element (2) at the bottom end of the drainage shield pipe (1) and arranging a water permeable hole (101) in the middle of the filter element (2), both the filter element (2) and the water permeable hole (101) can allow water to pass through and be discharged. That is, the fish feces deposited at the bottom and the fish feces suspended in the middle of the water body can be effectively discharged. When the plug (5) blocks the top opening of the drainage shield pipe (1), the top end and the periphery of the central pipe (3) are in a full water state, and drainage is carried out by using the siphon effect. With a large water pressure, the sewage can be smoothly discharged.

[0026] In a specific embodiment of the present invention, as Figure 1 and Figure 2 shown, the bottom wall of the aquaculture pond (7) is in a downward concave arc shape, and a receiving seat (701) is installed at the lowest position of the bottom wall of the aquaculture pond (7). The bottom opening of the filter element (2) is fixedly connected to the receiving seat (701). The top opening of the filter element (2) is inserted or threadedly connected to the bottom end of the central pipe (3).

[0027] By setting the bottom wall of the aquaculture pond (7) to be in a downward concave arc shape, the fish feces with a large density can be effectively precipitated to the periphery of the receiving seat (701), facilitating centralized discharge during drainage; through the arrangement of the receiving seat (701), it is convenient to seal the central pipe (3) and also convenient to install the filter element (2).

[0028] In a specific embodiment of the present invention, as Figures 1 to 3 shown, a water passing channel (501) is provided on the plug (5), and the water passing channel (501) communicates the side wall port and the bottom wall port of the plug (5).

[0029] Specifically, as Figures 1 to 3 shown, a gripping head (502) is provided at the top of the plug (5), and a concave arc-shaped groove is provided between the gripping head (502) and the main body of the plug (5).

[0030] By providing a water passing channel (501) on the plug (5), when it is necessary to fill water into the top opening of the drainage shield pipe (1) usually, the side wall port of the water passing channel (501) is exposed outside the top edge of the drainage shield pipe (1); during siphon drainage, it is necessary to press the plug (5) so that the side wall port is located below the top edge of the drainage shield pipe (1). Through the arrangement of the gripping head (502), it is convenient to lift the plug (5) upward.

[0031] In a specific embodiment of the present invention, as Figure 1 and Figure 2 shown, the fish-vegetable co-cultivation pond drainage device of the present invention further includes a drainage valve (6), and the drainage valve (6) is installed on the side wall of the drainage shield pipe (1), and the root position of the drainage valve (6) is higher than the top end of the central pipe (3).

[0032] Specifically, the drainage valve (6) is specifically a faucet valve, which is a manually opened or closed valve. When the drainage valve (6) is in the closed state, siphon drainage can be realized, and when the drainage valve (6) is in the open state, the water level is restricted and siphon drainage cannot be realized.

[0033] By adding a drain valve 6, it is possible to discharge the water body at the top of the drainage shield pipe 1 when the plug 5 is blocked, which plays a role in restricting the water level.

[0034] During the drainage process of the drainage device for the fish-vegetable co-culture pond of the present utility model, usually the water level is higher than the top opening of the drainage shield pipe 1, and the water body can enter the top of the drainage shield pipe 1 through the water passing hole 501, and the top end and the periphery of the central pipe 3 are in a full water state. When drainage is required, press down the plug 5 so that the side wall port of the water passing hole 501 is located below the top edge of the drainage shield pipe 1, and at the same time close the drain valve 6, that is, the top of the drainage shield pipe 1 is blocked. Open the water valve at the end of the drain pipe 4. At this time, the central pipe 3 and the drain pipe 4 are in a full water state, and drainage is carried out by the siphon effect. The water pressure and flow rate are large. The water body at the bottom of the culture pond 7 carries fish feces and enters the drainage shield pipe 1 from the bottom filter element 2, and flows upward, and is discharged from the top opening of the central pipe 3 to the drain pipe 4; at the same time, the water body in the middle of the culture pond 7 carries suspended small-density fish feces and enters the drainage shield pipe 1 through the water permeable hole 101, and flows upward, and is discharged from the top opening of the central pipe 3 to the drain pipe 4. The drain pipe 4 drains water to the vegetable planting bed for utilization. When the liquid level in the culture pond 7 is lower than the high-level water permeable hole 101, the drainage stops, and the water valve at the end of the drain pipe 4 is closed. At the same time, pull up the plug 5 so that the side wall port of the water passing hole 501 is exposed outside the top edge of the drainage shield pipe 1 to prepare for the next drainage.

[0035] To sum up, for the drainage device of the fish-vegetable co-culture pond of the present utility model, by arranging a filter element 2 at the bottom end of the drainage shield pipe 1 and opening a water permeable hole 101 in the middle, both the filter element 2 and the water permeable hole 101 can pass water and discharge, that is, both the fish feces deposited at the bottom and the fish feces suspended in the middle of the water body can be effectively discharged. When the plug 5 blocks the top opening of the drainage shield pipe 1, the top end and the periphery of the central pipe 3 are in a full water state, and drainage is carried out by the siphon effect. The water pressure is large, and the sewage can be smoothly discharged. In addition, by setting the bottom wall of the culture pond 7 to be a concave arc shape, the fish feces with a large density can be effectively precipitated to the periphery of the receiving seat 701, which is convenient for centralized discharge during drainage; through the setting of the receiving seat 701, it is convenient to seal the central pipe 3 and also convenient to install the filter element 2. By opening a water passing hole 501 on the plug 5, when it is necessary to fill water into the top opening of the drainage shield pipe 1 usually, the side wall port of the water passing hole 501 leaks outside the top edge of the drainage shield pipe 1; during siphon drainage, it is necessary to press the plug 5 so that the side wall port is located below the top edge of the drainage shield pipe 1. Through the setting of the holding head 502, it is convenient to pull up the plug 5. By adding a drain valve 6, it is possible to discharge the water body at the top of the drainage shield pipe 1 when the plug 5 is blocked, which plays a role in restricting the water level.
