[0002] Freshwater circulation can increase the dissolved oxygen content of water bodies. In aquaculture water bodies, the photosynthesis of aquatic plants and the respiration of aquatic animals cause fluctuations in dissolved oxygen levels. By using a circulation system, such as an aerator pump, to promote water flow, the water can be in full contact with air, increasing the amount of dissolved oxygen.

[0003] Therefore, a freshwater aquaculture water circulation system, with publication number CN222583394U, first closes the drain pipe through a valve, then opens the sealing cover; then seals and connects the external flushing pipe to the outlet pipe of the filter; the external flushing pipe is connected to an external water pump. After preparation, the external water pump is started, and the pumped clean water enters the filter through the external flushing pipe to flush the filter screen. After the food residue and excrement on the filter screen are flushed away, the resulting wastewater is discharged through the waste outlet and waste pipe.

[0004] However, during the recycling process, some water is discharged when food scraps and excrement are expelled, resulting in a waste of water resources. Utility Model Content

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] like Figures 1-4As shown, an aquaculture equipment and a freshwater circulation device for domestic fish include a treatment tank 1 and a collection tank 6. The collection tank 6 is installed at the bottom of the aquaculture equipment, and a filter screen is installed at the opening of the collection tank 6 to prevent freshwater fish from entering the collection tank 6. Therefore, the collection tank 6 is used to collect fish feces and uneaten fish feed generated during the aquaculture process. A filter box 11 and a return water box 17 are installed at the top and bottom of the treatment tank 1, respectively. A return water pump 8 is fixedly installed on the outer wall of the treatment tank 1. The inlet of the return water pump 8 extends to the bottom of the return water box 17. The freshwater used for aquaculture is filtered by the filter box 11 and then enters the return water box 17. The return water pump 8 then pumps the filtered freshwater in the return water box 17 back into the aquaculture equipment for circulation. A switch valve 13 is installed through the top of the filter box 11. One end of the switch valve 13 passes through the top of the treatment tank 1 and is connected to the inside of the collection tank 6 by a connecting pipe 5. When the switch valve 13 is opened, the water is circulated through the connecting pipe 5. Under the action of force, the fish feces and impurities collected in the collection tank 6 are mixed with water and flow into the filter box 11. The bottom of the filter box 11 is provided with a drain pipe 14 that is connected through to the top of the return water box 17. An electric telescopic rod 10 is fixedly installed on the outer bottom surface of the filter box 11. The telescopic end of the electric telescopic rod 10 passes through the bottom of the filter box 11 and is fixedly installed with a filter plate 12 that is slidably connected to the inner wall of the filter box 11. The fresh water entering the filter box 11 is filtered by the filter plate 12. After the filter box 11 is saturated, the electric telescopic rod 10 is extended to raise the filter plate 12. When the switch valve 13 is closed, the rise of the filter plate 12 is used to squeeze and dehydrate the impurities in the filter box 11. The side of the filter box 11 that is connected to the wall of the treatment box 1 is hollowed out and the wall of the filter box 11 is provided with a sealing cover 19 that is inserted into the hollow part of the filter box 11. By opening the sealing cover 19, it is convenient for personnel to collect the impurities that have been squeezed and dehydrated in the filter box 11.

[0025] Two sealing covers 19 are slidably connected to the sides of the filter plate 12, and a push plate 20 is embedded in the surface of one of the sealing covers 19. The side of the push plate 20 is slidably connected to the side of the filter plate 12, and a connecting rod 2 and a push rod 3 are provided on the other side of the push plate 20, which penetrate the sealing cover 19. A nut 4 is threadedly connected to the surface of the push rod 3 near the push plate 20. After the impurities in the filter box 11 are dehydrated, the sealing cover 19 without the push plate 20 is opened, and the nut 4 is rotated to move away from the sealing cover 19 until it is disengaged from the threaded part of the push rod 3. The push plate 20 can then be moved by pushing the push rod 3 with the assistance of the connecting rod 2. The four sides of the push plate 20 are in contact with the front, back and top edges of the filter box 11, and the bottom edge of the push plate 20 is in contact with the top edge of the filter plate 12. Therefore, by moving the push plate 20, the impurities in the filter box 11 that have been squeezed and dehydrated can be pushed out along the opened sealing cover 19. In addition, in this solution, a threaded groove is machined on the surface of the push rod 3 near the sealing cover 19 and threadedly connected to the nut 4.

[0026] A perforated frame 15 is fixedly installed on the top of the return water box 17. A filter element 16 is inserted into the perforated frame 15. A sealing plate 7 that is inserted into the wall of the treatment box 1 is fixedly installed at one end of the filter element 16. The filter surface of the filter element 16 is set facing the outlet of the drain pipe 14. When the fresh water filtered by the filter box 11 enters the return water box 17, it first enters the perforated frame 15 and is filtered by the filter element 16 in the perforated frame 15 to filter out fine impurities, thereby ensuring the quality of the fresh water that finally enters the return water box 17.

[0027] The bottom of the collection tank 6 has two symmetrically arranged base plates 9 hinged by torsion springs. The base plates 9 swing up and down, and their fulcrums are located near the center of the bottom of the collection tank 6. The inner walls of the collection tank 6 are each hinged with an inclined plate 18 by a torsion spring. The swinging edge of the inclined plate 18 slides on the upper surface of the adjacent base plate 9. Electric telescopic rods 10 are also fixedly installed through both ends of the outer bottom of the collection tank 6. The telescopic ends of the electric telescopic rods 10 at the bottom of the collection tank 6 are used to push the adjacent base plates 9 to swing. One end of the connecting pipe 5 is located between the two base plates 9, and the sides of the base plates 9 and inclined plates 18 are flush with the inner wall of the collection tank 6. The sliding connection allows the electric telescopic rod 10 at the bottom of the collection tank 6 to extend and push the corresponding base plate 9 upward against the spring force of the torsion spring. When the base plate 9 swings upward, it pushes the inclined plate 18 upward against the torsion force of the torsion spring. Conversely, when the electric telescopic rod 10 at the bottom of the collection tank 6 retracts, the base plate 9 and the inclined plate 18 automatically swing downward under the reset action of the torsion spring. Therefore, by repeatedly extending and retracting the electric telescopic rod 10 on the collection tank 6, the base plate 9 can be made to swing up and down back and forth. This allows the impurities collected at the bottom of the collection tank 6 and accumulated on the base plate 9 to slide towards the opening of the connecting pipe 5, ensuring the cleaning effect.

[0028] Working principle: The collection tank 6 is installed at the bottom of the aquaculture equipment or at the drain outlet. Fish feces or other impurities generated during the aquaculture process enter the collection tank 6 under the action of gravity and accumulate on the bottom plate 9. By repeatedly extending and retracting the electric telescopic rod 10 on the collection tank 6, the bottom plate 9 can be swung up and down, allowing the impurities collected at the bottom of the collection tank 6 and accumulated on the bottom plate 9 to slide towards the opening of the connecting pipe 5. When the switch valve 13 is opened, the fish feces and impurities collected in the collection tank 6, mixed with water, flow into the filter box 11. The fresh water entering the filter box 11 is filtered by the filter plate 12. The fresh water used for aquaculture enters the return water box 17 after being filtered by the filter box 11. Then, the return water pump 8 is used to pump the filtered fresh water in the return water box 17 back into the aquaculture equipment for recycling.

[0029] The wiring diagrams for the return water pump 8, electric telescopic rod 10, and switching valve 13 in this utility model are common knowledge in the field. Their working principles are known technologies. The appropriate model is selected according to actual use. Therefore, the control methods and wiring layouts of the return water pump 8, electric telescopic rod 10, and switching valve 13 will not be explained in detail.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
