Technical Field

[0001] This utility model relates to the field of water tank cleaning technology, specifically to a self-cleaning circulating aquaculture water tank. Background Technology

[0002] During fish farming and rearing in recirculating aquariums, fish excrement and uneaten feed easily settle and adhere to the bottom of the aquarium, making them difficult to filter out. If not cleaned promptly, this not only pollutes the water but can also negatively impact fish growth and health. Therefore, regular cleaning of the aquarium bottom is necessary. Currently, common cleaning methods involve using long-handled brushes or manually scrubbing the aquarium bottom, which is time-consuming, labor-intensive, and inconvenient or untimely. Utility Model Content

[0003] In view of this, it is necessary to provide a self-cleaning recirculating aquaculture pond that can prevent fish excrement and feed residue from adhering to the bottom of the pond.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A self-cleaning recirculating aquaculture pond includes a circular recirculating aquaculture pond and a bottom cleaning brush installed inside the pond. A drain pipe is vertically installed in the center of the pond bottom. The bottom cleaning brush is horizontally installed on the bottom of the pond. One end of the bottom cleaning brush is rotatably fitted onto the drain pipe, and the other end is a free end that extends towards the edge of the pond bottom. The bristles of the bottom cleaning brush are in contact with the bottom of the pond. A traction device is fixedly installed at the upper end of the free end of the bottom cleaning brush. At least one water inlet pipe is installed on the upper inner edge of the pond. The outlet of the water inlet pipe is inclined towards the water surface in the pond, spraying water. The impact force of the water causes the water in the pond to flow in a ring around the drain pipe. Under the driving force of the water flow, the traction device drives the bottom cleaning brush to rotate around the drain pipe in a circular motion around the bottom of the pond to clean the pond bottom.

[0006] Preferably, the traction device is a vertically arranged baffle.

[0007] Preferably, the traction device is a floating plate, which is fixed to the free end of the bottom cleaning brush by a traction rope or connecting rod. The floating plate floats on the water surface in the circulating aquaculture pool and is located directly above the free end of the bottom cleaning brush.

[0008] Preferably, a baffle plate is vertically installed at the bottom of the floating plate where it contacts the water surface.

[0009] Preferably, there are multiple water inlet pipes, which are evenly distributed around the circumference of the circulating aquaculture pool.

[0010] Preferably, it also includes a water filtration device, the inlet of which is connected to the outlet of the drain pipe, the outlet of which is connected to the inlet pipe, and a circulating water pump is installed at the outlet of the water filtration device. The drain pipe discharges water from the circulating aquaculture pool into the water filtration device for filtration, and the filtered clean water is transported to the inlet pipe by the circulating water pump.

[0011] Preferably, the water filtration device is a microfilter or a water filter.

[0012] Preferably, the height of the drain pipe is higher than the water surface, and a number of drain holes are provided on the side wall of the drain pipe. The drain holes are spaced apart along the height direction of the drain pipe and are evenly distributed along the circumference of the drain pipe.

[0013] Preferably, the traction force of the traction device is greater than the resistance of the pool bottom cleaning brush.

[0014] As can be seen from the above technical solution, this application provides a self-cleaning recirculating aquaculture pond. A drain pipe is vertically installed in the center of the pond bottom. A bottom cleaning brush is horizontally positioned on the bottom of the pond. One end of the bottom cleaning brush is rotatably fitted onto the drain pipe, and the other end is a free end extending towards the edge of the pond bottom. The bristles of the bottom cleaning brush contact the bottom of the pond. A traction device is fixedly installed at the upper end of the free end of the bottom cleaning brush. At least one water inlet pipe is installed along the edge, with the outlet of the inlet pipe tilted towards the water surface in the recirculating aquaculture tank to spray water. The impact force of the water causes the water in the recirculating aquaculture tank to flow in a circular motion around the drain pipe. Using the circulating water flow as a power source, the traction device drives the bottom cleaning brush to rotate circumferentially on the bottom of the recirculating aquaculture tank under the driving force of the water flow, performing uninterrupted self-cleaning operation. This prevents fish excrement and feed residue from settling and adhering to the bottom of the recirculating aquaculture tank, keeping the bottom of the tank clean and avoiding the trouble of manual cleaning, making fish farming and breeding work more convenient.

[0022] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0023] Please refer to Figure 1 and Figure 2This utility model provides a self-cleaning recirculating aquaculture pond, including a circular recirculating aquaculture pond 10 and a pond bottom cleaning brush 20 disposed within the recirculating aquaculture pond 10. A drain pipe 11 is vertically disposed in the center of the pond bottom within the recirculating aquaculture pond 10. The pond bottom cleaning brush 20 is horizontally disposed on the bottom of the recirculating aquaculture pond 10. A collar 22 is disposed at one end of the pond bottom cleaning brush 20, and the pond bottom cleaning brush 20 is rotatably sleeved on the drain pipe 11 through the collar 22, thus cleaning the pond bottom. The other end of the brush 20 is a free end, which extends from the center of the bottom of the recirculating aquaculture tank 10 to the edge of the bottom. The bristles of the bottom cleaning brush 20 are in contact with the bottom of the recirculating aquaculture tank 10. The bottom cleaning brush 20 can rotate freely around the drain pipe 11. A traction device is fixedly installed at the upper end of the free end of the bottom cleaning brush 20. The traction device is a vertically arranged baffle 25. The lower end of the baffle 25 is fixedly connected to the free end of the bottom cleaning brush 20 by bolts. The upper end of 5 extends towards the water surface. At least one water inlet pipe 12 is installed on the inner edge of the upper end of the recirculating aquaculture tank 10. The outlet of the water inlet pipe 12 is inclined towards the water surface in the recirculating aquaculture tank 10 to spray water. The impact force of the water causes the water in the recirculating aquaculture tank 10 to flow in a counterclockwise or clockwise circular motion around the drain pipe 11. Under the driving force of the water flow, the baffle 25 drives the bottom cleaning brush 20 to rotate freely in a circular motion around the drain pipe 11 on the bottom of the recirculating aquaculture tank 10, following the water flow. During rotation, the bottom cleaning brush 20 performs circumferential cleaning of the pond bottom. Utilizing water flow as its power, the bottom cleaning brush 20 self-cleans around the bottom of the recirculating aquaculture pond 10, preventing fish excrement and feed residue from settling and adhering to the bottom. Instead, it directs the excrement and feed residue towards the center of the recirculating aquaculture pond 10 with the water flow and discharges them through the drain pipe 11, keeping the pond bottom clean and avoiding the hassle of manual cleaning, thus making fish farming and breeding more convenient. In practical use, the sidewall of the baffle 25 faces the direction of water flow, and the width of the baffle 25 is set according to the resistance of the bottom cleaning brush 20, ensuring that the pushing force of the water flow on the baffle 25 is greater than the resistance of the bottom cleaning brush 20, guaranteeing that the bottom cleaning brush 20 can effectively clean the bottom of the recirculating aquaculture pond 10.

[0024] Please refer to Figure 1 or Figure 3 Furthermore, in order to improve the water flow in the recirculating aquaculture pool 10, multiple inlet pipes 12 are provided and evenly distributed around the circumference of the recirculating aquaculture pool 10. The outlets of the inlet pipes 12 are all inclined towards the water surface in the recirculating aquaculture pool 10 and spray water in the same direction. The impact force of the water is used to make the water in the recirculating aquaculture pool 10 flow in a counterclockwise or clockwise direction around the drain pipe 11, so as to use the water flow to drive the bottom cleaning brush 20 to perform a circular brushing in the recirculating aquaculture pool 10.

[0025] Please refer to Figures 3 to 6 In a preferred embodiment, the traction device is a floating plate 21. The floating plate 21 is connected to the free end of the bottom cleaning brush 20 by a traction rope 23 or a connecting rod. The floating plate 21 floats on the water surface in the recirculating aquaculture tank 10, so as to use the water flow to push the floating plate 21 to float in a circular motion in the recirculating aquaculture tank 10. The bottom cleaning brush 20 is pulled by the floating plate 21 to rotate freely around the drain pipe 11 on the circumference of the bottom of the recirculating aquaculture tank 10, and the bottom cleaning brush 20 is used to clean the bottom of the tank in a circular motion. In practical use, the length of the traction rope 23 is adjusted according to the water depth so that the floating board 21 floats above the free end of the pool bottom cleaning brush 20. In order to improve the traction of the floating board 21, a baffle plate 24 is vertically installed at the bottom of the floating board 21 where it contacts the water surface. The baffle plate 24 can increase the contact area between the water and the floating board 21, increase the thrust of the water on the floating board 21, and thus increase the traction of the floating board 21. This ensures that the traction of the floating board 21 is greater than the resistance of the pool bottom cleaning brush 20, making the pool bottom cleaning brush 20 operate more smoothly.

[0026] Please continue reading. Figure 1 or Figure 4 The self-cleaning recirculating aquaculture pool 10 also includes a water filtration device 30, which is a microfilter or water filter. The lower end of the drain pipe 11 is the outlet, and the lower end of the drain pipe 11 is installed through the bottom of the recirculating aquaculture pool 10. The water filtration device 30 is installed on one side of the recirculating aquaculture pool 10. The inlet of the water filtration device 30 and the outlet of the drain pipe 11 are connected to each other through a connecting pipe. The outlet of the water filtration device 30 and the inlet pipe 12 are connected to each other through a connecting pipe. A circulating water pump 31 is installed at the outlet of the water filtration device 30. Water in the recirculating aquaculture pool 10 is discharged into the water filtration device 30 through the drain pipe 11 for filtration. The filtered clean water is transported to the inlet pipe 12 through the circulating water pump 31 and then fed into the recirculating aquaculture pool 10 for recycling.

[0027] Please continue reading. Figure 4 Furthermore, the height of the drain pipe 11 is higher than the water surface, and a number of drain holes 13 are provided on the side wall of the drain pipe 11. The drain holes 13 are spaced apart along the height direction of the drain pipe 11 and are evenly distributed around the circumference of the drain pipe 11. This facilitates the flow of water from the upper, middle and lower layers of the circulating aquaculture pool 10 and impurities in the water into the drain pipe 11 through the drain holes 13, and then into the water filtration device 30 for filtration.

[0028] The self-cleaning recirculating aquaculture pond 10 does not require an additional drive device. It uses the circulating water flow as a power source to drive the bottom cleaning brush 20 to perform continuous cleaning operations, preventing fish excrement and feed residue from settling and adhering to the bottom of the recirculating aquaculture pond 10, keeping the bottom of the pond clean, avoiding the trouble of manual cleaning, and making fish farming and breeding work more convenient.

[0029] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
