Description

Technical Field

[0001] This utility model relates to the field of aquaculture pond technology, specifically to an ecological simulated flowing water aquaculture pond. Background Technology

[0002] Flow-through aquaculture is a highly efficient aquaculture model that provides sufficient dissolved oxygen to cultured organisms and removes metabolic waste in a timely manner through continuous water exchange, thereby achieving high stocking density and yield.

[0003] A search revealed that an invention patent with publication number CN119302255A discloses an aquaculture pond. The key technical features of the pond include a pond body, a filtration assembly and a cleaning assembly inside the pond body, a collection assembly connected to the outside of the pond body, and a water inlet pipe at the upper right side of the pond body. The filtration assembly includes a lifting frame that is slidably connected to the inner wall of the pond body. A filter frame is detachably connected to the upper side of the lifting frame, and a filter screen is installed inside the filter frame. The lifting frame is connected to a lifting mechanism.

[0004] Based on the search of the aforementioned patents and the findings of existing aquaculture ponds, traditional aquaculture ponds rely on multiple independent devices to complete water circulation, oxygenation, and filtration, which are complex and consume a lot of energy, resulting in high operating costs. In addition, the water flow in the aquaculture ponds is poorly organized, and the fish tend to remain still, affecting their growth, development, and health. Utility Model Content

[0005] The purpose of this invention is to provide an ecological simulated flowing water aquaculture pond, which solves the problems of complex equipment and poor water flow organization in traditional aquaculture ponds.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ecological simulated flowing water aquaculture pond, comprising an aquaculture pond and a treatment pond. A submersible pump is fixedly installed at the bottom inner side of the treatment pond. A vortex bend is fixedly connected to the output end of the submersible pump. The vortex bend penetrates the treatment pond and extends to the inner side of the aquaculture pond. A filter disc is fixedly connected to the middle inner side of the treatment pond. A rotating shaft is mounted on the middle upper end of the filter disc via a bearing. An impeller is fixedly connected to the top of the rotating shaft. A support is fixedly connected to the top of the aquaculture pond. A top seat is fixedly connected to the end of the support. A water pump is fixedly installed at the middle upper end of the top seat. The input end of the water pump penetrates the top seat and extends into the aquaculture pond. A water outlet pipe is fixedly connected to the output end of the water pump. The water outlet pipe is U-shaped, and its end is located above the impeller.

[0007] Preferably, a support ring is fixedly connected to the inner center of the treatment tank, below the filter disc, and the support ring contacts the filter disc. The support ring provides auxiliary support for the filter disc.

[0008] Preferably, a retention plate, which is conical in shape, is fixedly connected to the middle section of the rotating shaft. Before entering the treatment tank, the aquaculture water spreads further from the retention plate, thereby further increasing the oxygen content.

[0009] Preferably, the inclined surface of the retention tray has multiple annular grooves. By setting multiple annular grooves, as the aquaculture water flows from the inclined surface of the retention tray, some impurities inside can be retained in the annular grooves in sequence for preliminary filtration.

[0010] Preferably, a guide ring is fixedly connected to the upper inner side of the treatment tank, and the top of the guide ring is provided with an inclined surface. The inclined surface of the guide ring is inclined downward towards the inner circle, and the inner diameter of the guide ring is larger than the outer diameter of the retention plate. In this way, the aquaculture water guided by the retention plate can flow to the inclined surface of the guide ring, and then flow to the mesh of the filter plate.

[0011] Preferably, multiple supports are provided, and these supports are arranged in a circular array along the circumference of the aquaculture pond. By providing multiple supports, the top base can be supported.

[0012] Preferably, a fixing ring is fixedly connected to the outer side of the input end of the water pump, and multiple connecting brackets are fixedly connected to the bottom of the fixing ring. A retaining ring is fixedly connected to the ends of the multiple connecting brackets. The height of the retaining ring is higher than the lower inlet of the submersible pump's input end, and the retaining ring can block floating debris in the aquaculture pond, preventing it from being sucked into the submersible pump.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model uses a water pump to extract water from the bottom of the aquaculture pond and elevate it to an impeller at the top of the treatment pond. The water flow impact drives the impeller to rotate, creating a water curtain and spraying it out, greatly increasing the contact area and time between water and air, thus achieving highly efficient aeration and oxygenation. Simultaneously, the dispersed water flows sequentially through a retaining plate with annular grooves and a filter plate. The annular grooves retain larger particles of impurities, while the filter plate performs fine filtration. This design cleverly integrates oxygenation with a multi-stage physical filtration process, resulting in a compact structure.

[0014] 2. The purified water treated by this invention is directionally swirled within the aquaculture pond by a submersible pump and a vortex bend, effectively simulating the flow state of natural water bodies, which helps stimulate fish movement and thus comprehensively improves the ecological environment quality of the aquaculture water.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-4 An ecological simulated flowing water aquaculture pond includes an aquaculture pond 1 and a treatment pond 2, which are arranged side by side with the treatment pond 2 located to the left of the aquaculture pond 1. A submersible pump 3 is fixedly installed at the bottom inner side of the treatment pond 2, and a vortex bend 4 is fixedly connected to the output end of the submersible pump 3. The vortex bend 4 passes through the treatment pond 2 and extends to the inner side of the aquaculture pond 1. The vortex bend 4 is hook-shaped, and the hook part is located inside the treatment pond 2. After the submersible pump 3 re-inputs the treated aquaculture water from the treatment pond 2 back into the aquaculture pond 1, it can swirl along the inner circle of the aquaculture pond 1 to simulate the effect of ecological water flow. A filter disc 6 is fixedly connected to the middle inner side of the treatment pond 2, and a rotating shaft 7 is installed at the middle upper end of the filter disc 6 through a bearing. An impeller 8 is fixedly connected to the top of the rotating shaft 7.

[0019] Please see Figures 1-3 A retaining plate 9, which is conical in shape, is fixedly connected to the middle section of the shaft 7. Before entering the treatment tank 2, the aquaculture water spreads further from the retaining plate 9, thereby further increasing the oxygen content. Multiple annular grooves 91 are formed on the inclined surface of the retaining plate 9. By setting multiple annular grooves 91, some impurities inside the aquaculture water can be retained in the annular grooves 91 after flowing from the inclined surface of the retaining plate 9, undergoing preliminary filtration. A guide ring 10 is fixedly connected to the upper inner side of the treatment tank 2, and the top of the guide ring 10 is inclined. The inclined surface of the guide ring 10 is angled downwards towards the inner ring, and the inner diameter of the guide ring 10 is larger than the outer diameter of the retaining plate 9. In this way, the aquaculture water guided by the retaining plate 9 can flow to the inclined surface of the guide ring 10, and then flow to the mesh of the filter plate 6.

[0020] Please see Figures 1-3 A support frame 11 is fixedly connected to the top of the aquaculture pond 1. Multiple supports 11 are arranged in a circular array along the circumference of the pond 1. The supports 11 support a top seat 12. A top seat 12 is fixedly connected to the end of each support 11. A water pump 13 is fixedly installed at the upper center of the top seat 12. The input end of the water pump 13 passes through the top seat 12 and extends into the aquaculture pond 1. The output end of the water pump 13 is fixedly connected to an outlet pipe 14. The outlet pipe 14 is U-shaped, and its end is located above the impeller 8. After the water pump 13 draws in the aquaculture water 1, it sprays onto the impeller 8 through the outlet pipe 14. This causes the impeller 8 to rotate and disperses the aquaculture water, increasing contact with air and improving oxygen levels. A fixing ring 15 is fixedly connected to the outside of the input end of the water pump 13. Multiple connecting brackets 16 are fixedly connected to the bottom of the fixing ring 15. A retaining ring 17 is fixedly connected to the end of the multiple connecting brackets 16. The height of the retaining ring 17 is higher than the lower inlet of the input end of the submersible pump 3. The retaining ring 17 can block floating objects in the liquid level of the aquaculture tank 1 and prevent them from being sucked into the submersible pump 3.

[0021] The specific implementation process of this utility model is as follows: First, the water pump 13 operates, drawing wastewater rich in excrement from aquaculture organisms, uneaten feed, and low dissolved oxygen from below the surface of the aquaculture pond 1. The wastewater is lifted to the top of the treatment pond 2 through the outlet pipe 14. The U-shaped design of the outlet pipe 14 ensures that the outlet is precisely positioned above the impeller 8. The water flow falling from the outlet pipe 14 directly impacts the impeller 8. The force of the water flow drives the impeller 8 and the shaft 7 to rotate. The rotating impeller 8 disperses the water flow into fine water droplets and a water curtain, greatly increasing the contact area between water and air. This is a highly efficient aeration process, and the dissolved oxygen in the water increases rapidly. The oxygenated water flows onto the retention plate 9 below. Since the retention plate 9 is conical in shape with annular grooves 91 on its surface, the water flow spreads evenly and flows slowly along the inclined surface. Larger solid waste particles such as large pieces of feces and uneaten feed carried in the water flow are intercepted and retained by the annular grooves 91, achieving primary aeration. In the secondary filtration process, water flowing down from the edge of the retention tray 9 is caught and guided by the guide ring 10. The inclined design of the guide ring 10 ensures that the water flows evenly to the center area of ​​the filter tray 6. Under the action of gravity, the water flows through the filter tray 6, thus completing the secondary filtration of the aquaculture water. The water that has become clean and rich in oxygen after being filtered by the filter tray 6 collects at the bottom of the treatment tank 2. At this time, a clean water storage area is formed at the bottom of the treatment tank 2. The submersible pump 3 starts to work in this area and pumps the clean water back into the aquaculture tank 1 through the vortex bend pipe 4. Since the vortex bend pipe 4 is hook-shaped, its outlet direction is designed so that the water flows tangentially into the tank wall of the aquaculture tank 1 at a certain angle. This force will push the entire water body to form a continuous circulation in the circular aquaculture tank, simulating the flow of a natural river. In this way, not only is the water in the aquaculture tank 1 mixed evenly, but the water flow also stimulates the activity of the aquaculture organisms, enhances their physical condition, and makes them closer to their natural growth environment.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art 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 appended claims and their equivalents.
