Technical Field
[0001] The utility model relates to the technical field of fish pond sewage discharge devices, in particular to a fish pond sewage discharge device of a circulating water culture system. Background Art
[0002] According to the traditional breeding equipment system, the water in the breeding pond is directly discharged into the nearby sea after being polluted, which will inevitably affect the safety of the water body in the long run. Pollution of local sea areas, destruction of coastal ecological balance, leading to the prevalence of shrimp and fish diseases in large areas of breeding areas, and red tides in coastal areas, seriously threatening the development of shrimp and fish farming. Therefore, there is an urgent need for an effective and sustainable scientific method to solve the concentration and removal of sewage in the breeding pond, timely remove the residual bait and metabolites of shrimp and fish in the pond, and energy-saving and efficient feasible measures and devices to maintain the safety of the water environment in the pond. At present, the sewage treatment methods of shrimp and fish ponds in my country mainly use biological and chemical methods to decompose and precipitate pollutants, but these methods are complicated and costly, uneconomical, impractical, and unpopular. There are also some latest technologies that use physical methods and use the principle of hydrodynamic drive to realize a system that can automatically collect and discharge sewage without adding any biochemical drugs.
[0003] The prior art provides a variety of aquaculture sewage discharge technologies, but there are no measures to prevent the equipment from being corroded and aged due to long-term use. The water quality monitoring is imperfect, and the sewage collection and discharge effect needs to be improved. The aquaculture pond is surrounded by earth embankments on the land. Aquatic organisms can be cultured by adding aquaculture water to the aquaculture pond, and then the aquatic organisms can be bred in large quantities by adding feed into the aquaculture pond. The aquaculture pond in the prior art is prone to environmental deterioration due to the accumulation of residual bait and aquatic excrement, which is not conducive to the growth of aquatic organisms. Therefore, the aquaculture pond is regularly allowed to rest and the excrement at the bottom of the pond is removed to maintain the environment of the aquaculture pond. When the aquaculture pond is resting, all the aquatic organisms in the aquaculture pond must be removed and then the water in the pond must be discharged. It not only consumes a large amount of water, but also the bottom soil must be exposed to the sun for a period of time. It is easily affected by the climate, resulting in a prolonged rest time, which in turn affects the lack of aquaculture schedule. Therefore, a fish pond sewage discharge device for a circulating water aquaculture system is proposed. Utility Model Content
[0004] In order to solve the problems raised in the above-mentioned background technology, the purpose of the utility model is to provide a fish pond sewage discharge device for a recirculating aquaculture system, which has the advantages of not needing to scoop out all the fish and shrimp in the pond before changing the water, and is not prone to accumulation of leftover bait and aquatic creature excrement. Even if it occurs, it can be discharged and cleaned through the large central drainage sewage outlet, thus solving the problem that leftover bait and aquatic creature excrement need to be scooped out when changing the water, which is easy to accumulate and inconvenient to discharge.

[0006] As a preferred embodiment of the present invention, there is a solid part between the side sliding opening and the periphery of the large drainage and sewage outlet, and there is a certain distance between them.
[0007] As a preferred embodiment of the utility model, the locking hole opened in the middle layer of the fish pond body is a circular ring, and disconnected locking holes are also opened at the bottom of the inner cavity of the fish pond body and the locking hole in the middle layer to facilitate direct entry of the locking ring.
[0008] As a preferred embodiment of the present invention, the heights of the outer column and the inner column are inconsistent, and the height of the inner column is only two-thirds of the height of the outer column, but they are fixedly connected by connecting plates on all sides.
[0009] As a preferred embodiment of the present invention, the diameter of the small leakage hole is designed to be smaller than that of a normal shrimp.
[0010] As a preferred embodiment of the present invention, the surface of the connecting slide is made of silicone.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] 1. The utility model uses a small leak hole, an outer column, a large drainage and sewage outlet and an inner pipe column in coordination so that small dirt can be discharged through the side sliding port when it is not needed to be discharged, so there is no need to clean it frequently and there is no need to face the problem of troublesome cleaning.

The small leakage hole 8 is opened above the connection between the outer surface of the fish pond main body 1 and the connecting column 6. The diameter of the small leakage hole 8 is designed to be smaller than that of normal shrimps, so that it can meet the size of normal residual bait and biological excrement, and will not easily cause blockage due to water flow. The pull ring 9 is fixedly connected to the top center position of the outer column 5, and the bottom discharge pipe 10 is fixedly connected to the bottom center position of the fish pond main body 1 and connected to the side sliding port 3. The external connecting pipe 11 is sleeved on the periphery of the bottom discharge pipe 10, and the left side of the discharge pipe 12 is connected to the bend of the discharge pipe 12. The connecting sliding port 14 is set At the top of the large drainage and sewage outlet 2, the surface of the connecting slide 14 is made of silicone material so that it can be in close contact with the fish pond main body 1 when connected, and no water leakage will occur. The inner pipe column 13 is fixedly connected to the top of the connecting slide 14. The heights of the outer column 5 and the inner pipe column 13 are inconsistent. The height of the inner pipe column 13 is only two-thirds of the height of the outer column 5, but it is fixedly connected by connecting plates on all sides. When the horizontal line exceeds the inner pipe column 13, the siphon principle can be triggered, and the polluted water in the fish pond main body 1 can be directly discharged. When cleaning is needed, the outer column 5 can be rotated to pull out the inner pipe column 13, and the water can be discharged directly through the small leakage hole 8, the outer column 5, the large drainage and sewage outlet 2 and the inner pipe column 13. When used in combination, small dirt can be discharged through the side slide 3 when there is no need for discharge, so there is no need for frequent cleaning, nor is there any need to face the problem of troublesome cleaning. In addition, the height between the outer column 5 and the inner tube column 13 is inconsistent. The height of the inner tube column 13 is only two-thirds of the height of the outer column 5. When changing the water, the water can be filled and the horizontal plane exceeds the height of the inner tube column 13, thus forming a siphon principle, which can automatically draw out the water source in the fish pond main body 1, and the remaining water source can be directly drawn out by rotating the outer column 5 to lift the inner tube column 13. In this way, the large drainage and sewage outlet 2 can be directly observed by the naked eye. For normal cleaning, the cleaned debris can be directly pushed to the large drainage and sewage outlet 2 for discharge downward.
