In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0019] like Figure 1-6 A fish aquaculture system includes: an aquaculture unit 1, a water treatment unit 2, and a water recirculation unit 3; The aquaculture facility 1 includes: an aquaculture pond 11, a hanging net bag 12, and an oxygen supply component 13; The aquaculture pond 11 is equipped with a hanging water trough 111; the hanging water net bag 12 is set in the middle of the hanging water trough 111 and separates the hanging water trough 111 into upper and lower layers; the bottom wall of the hanging water trough 111 is provided with a drain outlet 112; the output end of the oxygen supply component 13 is connected to the hanging water trough 111 and is used to output oxygen or air to the aquaculture water in the hanging water trough 111. The water treatment unit 2 includes: a water treatment tank 21, a water processor 22, and a water inlet pipe 23; The water treatment tank 21 is provided with a plurality of treatment sub-slots 211 in sequence along its length, and adjacent treatment sub-slots 211 are connected in sequence; some of the water treatment tank 21 is provided with the water processor 22; the input end of the water inlet pipe 23 is connected to the sewage outlet 112, and the output end of the water inlet pipe 23 is connected to the treatment sub-slot 211 at the beginning of the water treatment tank 21; The water return mechanism 3 includes: a water return pipe 31 and a pump body 32; The input end of the water return pipe 31 is connected to the treatment sub-slot 211 at the end of the water treatment tank 21, the output end of the water return pipe 31 is connected to the hanging water tank 111, and the pump body 32 is installed on the water return pipe 31.

[0020] This solution provides a fish suspending water aquaculture system. By setting up a suspending net bag 12 in the aquaculture pond 11 to separate impurities from the fish and the aquaculture water, the impurities are output to the water treatment pond 21 through the water inlet pipe 23. In the water treatment pond 21, the water is treated by the water processor 22 in different treatment tanks 211. Finally, the treated aquaculture water is returned to the aquaculture pond 11 through the water inlet pipe 23, realizing the reuse of aquaculture water and solving the problems of large water consumption and serious water pollution during fish suspending water aquaculture.

[0021] Specifically, the aquaculture pond 11 has a hanging water trough 111 filled with aquaculture water; a hanging net bag 12 is installed in the hanging water trough 111, dividing the aquaculture water into upper and lower parts; the upper part inside the hanging net bag 12 is used to hold fish. The water treatment mainly involves reducing or stopping feeding, allowing the fish to consume the fat accumulated in their abdominal cavity. The oxygen supply component 13 delivers oxygen to the aquaculture water in the hanging water trough 111. Oxygen can increase the activity of the fish, thereby improving their metabolism; the fish cannot pass through the opening of the hanging net bag 12, and the fish's metabolites and feed impurities will sink under gravity and sink through the opening of the hanging net bag 12 to the bottom wall of the hanging water trough 111, and be discharged through the drain outlet 112 to the water inlet pipe 23; the water inlet pipe 23 discharges the impurities along with the aquaculture water to the water treatment pond. 21; The water treatment tank 21 is provided with multiple treatment sub-tanks 211 arranged in sequence. Some of the treatment sub-tanks 211 are equipped with water processors 22. The water processors 22 are known mechanisms with functions such as dirt separation, dirt removal, sewage discharge, filtration, and purification, such as conventional water purification devices. Thus, when the aquaculture water flows from the initial treatment sub-tank 211 to the final treatment sub-tank 211, different water processors 22 perform dirt separation, dirt removal, sewage discharge, filtration, or purification on the aquaculture water, ultimately ensuring that the aquaculture water in the final treatment sub-tank 211 meets the aquaculture requirements. At this time, the water return mechanism 3 is used to return the aquaculture water from the treatment sub-tank 211 back to the aquaculture mechanism 1. The pump 32 is activated, and the pump 32 enables the water return pipe 31 to transport the aquaculture water from the final treatment sub-tank 211 to the hanging water tank 111. Figure 1The aquaculture water from the initial treatment tank 211 is transported to the final treatment tank 211, so that the treated aquaculture water can be reused in the aquaculture pond 11. In this way, the aquaculture water circulates between the aquaculture unit 1, the water treatment unit 2, and the water return unit 3. Impurities involved in the fish hanging water treatment will be concentrated in the treatment tank 211 and purified and filtered by the water processor 22, thereby maintaining the fish in a clean water environment and reducing the waste of aquaculture water. This solves the problems of large water consumption and serious water pollution during fish hanging water aquaculture.

[0022] Alternatively, the oxygen supply assembly 13 may include: an inlet hose 131 and an annular tube 132; The output end of the input hose 131 is connected to the annular tube 132 for supplying oxygen or air to the annular tube 132; the annular tube 132 is provided with a plurality of oxygen supply holes 1321 facing the center; the annular tube 132 is set in the aquaculture water of the suspended water tank 111 and is located above the suspended water net bag 12.

[0023] This design uses a ring pipe 132 to supply oxygen or air to the suspended water tank 111. The ring pipe 132 has multiple oxygen supply holes 1321 facing the center, which are arranged in a ring. The input hose 131 outputs oxygen or air to the ring pipe 132, and the oxygen or air is discharged through the oxygen supply holes 1321. Because the ring pipe 132 has multiple oxygen supply holes 1321, the oxygen content of the aquaculture water is high near the ring pipe 132. When multiple oxygen supply components 13 are arranged, the oxygen content at multiple locations can be increased. At the same time, the multiple oxygen supply holes 1321 of the ring pipe 132 can increase the air pressure near the ring pipe 132, thereby increasing the water flow and promoting fish swimming.

[0024] Optimally, the oxygen supply assembly 13 includes: an oxygen supply pipe 133 and a proportional valve 134; The oxygen supply pipe 133 is disposed above the aquaculture pond 11 and extends along the length of the aquaculture pond 11; oxygen or air is introduced into the oxygen supply pipe 133; different positions of the oxygen supply pipe 133 are respectively connected to the input end of the input hose 131, and the proportional valve 134 is installed on the input hose 131.

[0025] Oxygen or air is introduced into the oxygen supply pipe 133. The oxygen or air can be output to the input hose 131 through different horizontal positions of the oxygen supply pipe 133. The input hose 131 then outputs to the hanging water tank 111 through the ring pipe 132, thus increasing the oxygen content at different positions in the hanging water tank 111. Simultaneously, each input hose 131 is equipped with a proportional valve 134. Operators can adjust the opening ratio of the proportional valve 134 according to actual conditions, thereby regulating the output of oxygen or air. When the proportional valve 134 allows a small amount of oxygen or air to pass through, it can meet the basic hanging water needs of the fish. When the proportional valve 134 allows more oxygen or air to pass through, the flow rate of the oxygen or air increases the flow of the aquaculture water, thereby promoting fish movement and metabolism.

[0026] Alternatively, the aquaculture facility 1 may further include: a rinsing shower head 14; Part of the water return pipe 31 is disposed above the aquaculture tank 11 and extends along the length of the aquaculture tank 11. The rinsing spray head 14 is movably and adjustablely installed on the water return pipe 31 above the aquaculture tank 11 and distributed at different horizontal positions of the aquaculture tank 11. The input end of the rinsing spray head 14 is connected to the output end of the water return pipe 31, and the output end of the rinsing spray head 14 faces the hanging water tank 111.

[0027] Part of the water return pipe 31 can be directly connected to the hanging water tank 111; part of the water return pipe 31 can also be indirectly connected to the hanging water tank 111 through the flushing head 14. The water return pipe 31 is set above the breeding tank 11. When the flushing head 14 is turned on, the breeding water of the water return mechanism 3 can be returned to the hanging water tank 111. The flushing head 14 can move freely and its water outlet direction can be manually adjusted, or it can be fixed to the buckle of the water return pipe 31. The flushing head 14 can wash away impurities on the surface of the breeding tank 11 and the hanging water net bag 12, thereby washing away the impurities remaining in the breeding tank 11 and the hanging water net bag 12. The impurities can move with the breeding water and be processed by the water processor 22 of the treatment tank 211.

[0028] Optimally, some of the water processors 22 are brushes 221; multiple brushes 221 are disposed in the same processing tank 211, the bristles of the brushes 221 extend along the height direction of the processing tank 211, and the bristles of two adjacent brushes 221 are close to or in contact with each other.

[0029] The processing tank 211 is equipped with several brush components 221. The bristles of each brush component 221 can extend along the height direction of the processing tank 211 to ensure that the bristles cover the entire processing tank 211. The brush components 221 are mainly used for coarse filtration of impurities. The bristles of the brush components 221 restrict larger impurities from entering the next processing tank 211, thereby reducing the processing load of the water processor 22 in the subsequent processing tank 211. Larger impurities are difficult to enter the next processing tank 211.

[0030] Alternatively, the water treatment mechanism 2 may further include: a crossbar 24; The processing trough 211 has hanging rod platforms 212 on both sides of the trough opening; the crossbar 24 is horizontally arranged on the upper surface of the hanging rod platforms 212 on both sides; the upper end of the brush 221 is provided with a hanging ring 2211, and a single crossbar 24 passes through the hanging rings 2211 of multiple brushes 221 at the same time, so that multiple brushes 221 are vertically suspended in the processing trough 211.

[0031] There can be multiple crossbars 24. Each crossbar 24 is placed horizontally on the hanging platform 212 on both sides of the opening of the processing slot 211. The hanging platform 212 can support the crossbar 24. The upper end of the brush component 221 is provided with a lifting ring 2211. When a single supporting crossbar 24 is inserted into the lifting ring 2211 of different brush components 221, multiple brush components 221 will be suspended in the processing slot 211. This can reduce the installation difficulty of the brush components 221 while ensuring that more brush components 221 can be installed.

[0032] Optimally, the upper surface of the hanging rod platform 212 exposes the platform fasteners 213, and some adjacent platform fasteners 213 are separated to form a limiting gap 214; the end of some of the crossbars 24 is limited in the limiting gap 214.

[0033] Platform fastener 213 is used to fix the hanging rod platform 212 to the slot of the processing slot 211, or platform fastener 213 is used to fix the split hanging rod platform 212 into one piece. In short, the upper surface of the hanging rod platform 212 exposes the end of the platform fastener 213. The platform fastener 213 is a known fastener, including bolts, studs, screws, nuts, washers, pins, etc. The platform fasteners 213 exposed on the upper surface of the hanging platform 212 can be screw heads, threaded rods, or nuts. This solution cleverly utilizes the platform fasteners 213 exposed on the upper surface of the hanging platform 212. A limiting gap 214 is formed between two adjacent platform fasteners 213. The end of the crossbar 24 is limited in the limiting gap 214. The platform fasteners 213 limit the horizontal position of the crossbar 24, which can prevent the crossbar 24 from rolling horizontally on the hanging platform 212. This structure facilitates the disassembly and installation of the brush component 221 on the crossbar 24. The crossbar 24 only needs to be lifted upwards to disengage from the limiting gap 214, thereby allowing the brush component 221 to be installed or removed.

[0034] Optimally, two adjacent processing sub-slots 211 are separated by a frame slot 215; part of the water processor 22 is a filter plate 222, which is detachably installed in the frame slot 215; the brush 221 is closer to the output end of the water inlet pipe 23 than the filter plate 222.

[0035] like Figure 1 The arrows indicate the flow direction of the aquaculture water. The brush 221 is relatively close to the treatment tank 211 at the beginning of the water treatment tank 21, and the filter plate 222 is relatively close to the treatment tank 211 at the end of the water treatment tank 21. Adjacent treatment tanks 211 are separated by frame grooves 215. The filter plates 222 are set in different frame grooves 215. When the pump body 32 pumps water into the end treatment tank 211, the aquaculture water can be driven through multiple filter plates 222, so that impurities are retained in the treatment tank 211. The water purification device in the treatment tank 211 will purify the impurities.

[0036] Optimally, it also includes: a water replenishment mechanism 4; The water replenishment mechanism 4 includes: a water replenishment pipe 41 and a water replenishment valve 42; The output end of the water supply pipe 41 is connected to the treatment sub-tank 211 at the end of the water treatment tank 21. The water supply pipe 41 is used to output tap water or aquaculture water to the treatment sub-tank 211 at the end. The water supply valve 42 is installed on the water supply pipe 41.

[0037] When the overall water supply in the fish aquaculture system is insufficient, the water supply valve 42 can be opened, and the water supply pipe 41 is connected to the faucet or the water storage tank 6. The water supply pipe 41 outputs tap water or aquaculture water to the treatment tank 21 at the end of the water treatment tank 21, and outputs it directly to the aquaculture tank 11 through the water return pipe 31, thereby replenishing the water content in the system.

[0038] Optimally, it also includes: a drain pipe 5 and a water storage tank 6; The drain pipe 5 passes through the treatment sub-channel 211 at the beginning of the water treatment tank 21; The output end of the drain pipe 5 is connected to the water storage tank 6; the input end of the drain pipe 5 faces upwards and is located below the horizontal plane of the opening of the processing trough 211.

[0039] When the water volume in the fish aquaculture system is excessive, for example, when the aquaculture pond 11 outputs a large amount of water to the treatment sub-tank 211 at the beginning of the water treatment pond 21, the aquaculture water may spill onto the ground. To address this, in this embodiment, a drain pipe 5 is provided at the treatment sub-tank 211 at the beginning of the water treatment pond 21. The input end of the drain pipe 5 is below the horizontal plane where the opening of the treatment sub-tank 211 is located. When the liquid level in the treatment sub-tank 211 is higher than the input end of the drain pipe 5, the aquaculture water will be output to the storage tank 6 through the drain pipe 5 for temporary storage, thereby avoiding waste of aquaculture water. The aquaculture water in the storage tank 6 can be added to the system later through the water return pipe 31 or the water replenishment pipe 41.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
