[0002] Freshwater fish temporary culture refers to the short-term cultivation management of fish in a specific environment to improve the quality, adaptability and market value of fish. Generally, freshwater fish are stocked in spring and caught in winter. Therefore, there is often a seasonal market saturation of fish in winter, resulting in price competition and poor economic benefits. In spring and summer, the supply of freshwater fish on the market is less, and the market supply is uneven between peak and off-peak seasons. Practice has proved that temporary culture in winter can not only adjust the supply of freshwater fish in the market, but also improve economic benefits.

[0003] Chinese patent with the patent publication number CN218851649U discloses a culture box for freshwater fish, including a box body, an end cover, a bracket, a suction pipe, a one-way valve, a connecting pipe, a first water pump and a filter box.

A connecting frame 6 is fixedly connected to one side of the cross bar 5, and a filter plate 15 is fixedly connected to the other side of the cross bar 5. The filter plate 15 only allows water to pass through to prevent dirt generated after brushing from flowing with the fish. A plurality of rotating shafts 8 are rotatably connected to the bottom of the connecting frame 6. Fixing blocks 11 are fixedly connected to the bottoms of the rotating shafts 8. Brush hairs 12 are arranged at the bottoms of the fixing blocks 11. One ends of the rotating shafts 8 all penetrate through the bottom side wall of the connecting frame 6 and are fixedly connected with driven bevel gears 9. A transmission shaft 7 is rotatably connected to the top of the connecting frame 6. Driving bevel gears 10 are fixedly connected to the transmission shaft 7 at positions corresponding to the driven bevel gears 9. A slot 16 is opened on the inner wall of one end of the box body 1. A plug board 17 is inserted and connected in the slot 16. A first water inlet pipe 18 and a second water inlet pipe 19 are respectively arranged at both ends of the top of the box body 1. A first drain outlet 20 and a second drain outlet 21 are respectively arranged at both ends of the bottom of the box body 1. Initially, the cross bar 5 is located at one end close to the first water inlet pipe 18.

[0029] As shown Figures 1-7 in the figure, a limiting rod 3 is fixedly connected inside a chute 2 on one side. One end of a cross bar 5 is slidably connected to the limiting rod 3. A screw rod 4 is rotatably connected inside the chute 2 on one side. One end of the screw rod 4 is threadedly connected to the cross bar 5. One side of the box body 1 is fixedly connected with a first motor 13 at a position corresponding to the screw rod 4. The output end of the first motor 13 penetrates through the side wall of the box body 1 and is fixedly connected with one end of the screw rod 4. Starting the first motor 13 drives the screw rod 4 to rotate, and then drives the cross bar 5 to move horizontally left and right along the chute 2, facilitating the use of a filter plate 15 to push and drive the freshwater fish, and at the same time using a number of fixing blocks 11 and brush hairs 12 to move horizontally to clean and brush the bottom side wall of the box body 1.

The insertion plate 17 can divide the interior of the box body 1 into two parts. The right part is used for daily temporary cultivation of freshwater fish. The first water inlet pipe 18 and the first drain port 20 are used for water filling and draining of this part. The left part is used to push the freshwater fish into it for temporary storage when the right part of the box body 1 is being cleaned or changed water. The second water inlet pipe 19 and the second drain port 21 are used for water filling and draining of this part. Oxygenation pumps 23 are arranged at both ends of the box body 1. The output ends of the oxygenation pumps 23 are fixedly connected with output pipes 24. One end of each output pipe 24 communicates with the inside of the box body 1, and can respectively increase the dissolved oxygen in the water bodies of the left and right parts, ensuring the growth requirements of the freshwater fish and preventing the freshwater fish from dying due to lack of oxygen. A flow divider 25 is arranged at the end of each output pipe 24, which plays a role in evenly distributing oxygen in the water. Drain pipes 22 are arranged at the bottom of the box body 1 at positions corresponding to the first drain port 20 and the second drain port 21.

Initially, the cross bar 5 is located at one end close to the first water inlet pipe 18. When it is necessary to clean the interior of the box body 1, the plug board 17 is pulled out, and the first motor 13 is started, thereby driving the screw rod 4 to rotate, and then driving the cross bar 5 to move horizontally to the left along the sliding groove 2. At the same time, the second motor 14 is started, thereby driving the transmission shaft 7 to rotate, so that several driving bevel gears 10 rotate along with the transmission shaft 7, and then driving the driven bevel gears 9 meshing with the driving bevel gears 10 to rotate, thereby driving the corresponding rotating shafts 8 to rotate, and then driving the fixing blocks 11 at the bottom of the rotating shafts 8 to rotate, using the brush hairs 12 on its bottom side to clean and brush the bottom side wall of the box body 1, brushing off the dirt attached to the surface. At the same time, the filter plate 15 pushes the freshwater fish temporarily raised in the box body 1 towards the side of the plug board 17, and all the freshwater fish are pushed to the left part of the box body 1. Subsequently, the plug board 17 is reinserted and the connection bolts are tightened for fixation. The sewage inside the right part is completely drained through the first drain port 20, and water is re-filled into the right part through the first water inlet pipe 18. The first motor 13 is started in the reverse direction to drive the cross bar 5 to move to the right and reset. The water inside the left part is drained through the second drain port 21. The plug board 17 is pulled out again, and the freshwater fish are manually pushed with a fishing net to swim to the right part, and then the plug board 17 is reinserted and fixed. Thus, the cleaning and water change of the right part are completed, and the remaining water in the left part can be drained through the second drain port 21.
