[0002] Fish, shrimp, crabs, and other aquatic products are typically raised in aquaculture ponds. Aquaculture requires oxygen and produces uneaten feed and excrement. Heavier waste settles and separates to the bottom of the pond, while lighter floating debris remains on the surface, deteriorating water quality. To create a healthy aquaculture environment, the low-quality, low-oxygen water in the ponds needs to be drained to a purification and oxygenation zone to obtain high-quality, high-oxygen water, which is then reintroduced into the ponds, thus achieving water circulation.

[0003] The water circulation in existing aquaculture systems is generally achieved by using water pumps, which consumes a lot of energy, is not environmentally friendly, and is also costly. Utility Model Content

[0011] In a preferred embodiment, in the first aspect of this utility model, the water inlet area surrounds the periphery of the pool body, and a plurality of water inlets are provided on the outer periphery of the water inlet area. The water outlet area surrounds the periphery of the pool body and is located above the water inlet area.

[0022] To better understand and implement this invention, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0023] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0025] See Figure 1 This utility model provides a breeding pond, including: a pond body 1, the pond body 1 is provided with a water inlet area 11 and a water outlet area 12, the water inlet area 11 is connected to a water inlet component 2, the water inlet component 2 includes a water inlet pipe 21 and an air inlet pipe 22, one end of the water inlet pipe 21 is connected to the water inlet area 11 and the air inlet pipe 22, and the other end of the water inlet pipe 21 is connected to the inside of the pond body 1 so as to mix water and gas and introduce them into the pond body 1 for aeration, and the water in the pond body 1 fluctuates upward due to aeration so that the water in the pond body 1 can flow into the water outlet area 12.

[0026] Aquaculture ponds are part of an aquaculture system used to raise fish, shrimp, crabs, and other aquatic products. Aquaculture requires oxygen and produces uneaten feed and excrement. Heavier waste settles and separates to the bottom of the pond, while lighter floating debris floats on the surface, deteriorating water quality. To create a good aquaculture environment, the low-quality, low-oxygen water in the ponds needs to be drained to a purification zone for purification and oxygenation, resulting in high-quality, high-oxygen water that is then reintroduced into the ponds, thus achieving water circulation.

[0027] In this invention, water is introduced into the aquaculture pond via an inlet assembly 2. The inlet assembly 2 is connected to an inlet pipe 21 and an air inlet pipe 22. One end of the inlet pipe 21 connects to the inlet area 11 and the air inlet pipe 22, while the other end connects to the interior of the pond body 1. This allows water and gas to be introduced into the pond body 1 using the lifting force of the gas. This not only achieves micro-powered water introduction into the pond body 1 but also facilitates the uniform dissolution of gas in the water, increasing the dissolved oxygen concentration and achieving high oxygen content. Simultaneously, the gas generates numerous bubbles in the water, causing water ripples and raising the water level above the outlet area 12. Water with low quality and low oxygen content, containing floating debris, automatically flows out of the outlet area 12 for subsequent purification and oxygenation. Thus, when applied to an aquaculture system, this aquaculture pond achieves water circulation, purification, and oxygenation through micro-power, significantly reducing energy consumption, meeting energy conservation and environmental protection requirements, and helping to lower aquaculture costs.

[0028] It should be noted that the aquaculture pond can be any shape, such as round or square, and the material can be corrosion-resistant materials such as PP plastic, without any special restrictions.

[0029] An air inlet pipe 22 connects to an oxygen supply device via an oxygen delivery pipe 4. Multiple water inlet components 2 are spaced around the outer perimeter of the tank body 1. The oxygen delivery pipe 4 is arranged in a ring at the top of the tank body 1. The oxygen supply device can be a common type of air inlet pipe or oxygen generator, and its gas flow rate is determined by the stocking density, temperature, and dissolved oxygen rate in the aquaculture tank; specific selection is made based on the specific circumstances. The oxygen supply device delivers air into the tank body 1 to increase the oxygen content.

[0030] Multiple water inlet components 2 are spaced around the outer perimeter of the tank body 1, preferably evenly spaced, to ensure uniform oxygen supply to the tank body 1. This guarantees sufficient oxygen for all water within the tank body 1, preventing the formation of oxygen-deficient areas, thus promoting faster growth and ensuring the health of aquatic organisms, enabling high-density aquaculture. The annular oxygen supply pipe 4 further enhances the uniformity of dissolved oxygen in the water by uniformly supplying oxygen to the multiple water inlet components 2.

[0031] The inlet pipe 21 includes an inlet section 211 and an oxygenation section 212. One end of the inlet section 211 is connected to the inlet area 11. The inlet section 211 extends downward from the inlet area 11 so that its other end is connected to one end of the oxygenation section 212. One end of the oxygenation section 212 is also connected to the air inlet pipe 22. The other end of the oxygenation section 212 extends upward and communicates with the interior of the pool body 1.

[0032] The inlet section 211 is vertically arranged, with one end located at the top and the other end at the bottom. The inlet area 11 is located above the inlet section 211, and one end of the inlet section 211 is directly connected to the inlet area 11, allowing water in the inlet area 11 to automatically flow into the inlet section 211 and then to the other end. The other end of the inlet section 211 and one end of the air inlet pipe 22 are both connected to one end of the oxygen mixing section 212, which is vertically arranged with one end at the bottom and the other at the top. In this way, the water in the inlet section 211 and the gas in the air inlet pipe 22 directly enter one end of the oxygen mixing section 212 and can be fully mixed and dissolved within it, thus ensuring the uniformity of dissolved oxygen in the water flowing into the tank 1. It can also use the air lift force of the gas to push water into the pool 1, realizing micro-powered water intake.

[0033] Furthermore, taking the connection point between the other end of the mixing section 212 and the pool body 1 as the base point, the angle between the radial extension line of the pool body 1 at the base point and the extension direction of the mixing section 212 at the base point is 30-60°. Preferably, the angle is 45°. The gas-liquid mixture in the mixing section 212 enters the pool body 1 at a certain inclined angle, which can form a dynamic jet, thereby forming a rotating vortex in the pool body 1. This is beneficial for the uniform dissolution of oxygen and for the downward sedimentation and separation of heavier fecal waste, thus accelerating the efficiency of fecal waste separation. At the same time, the gas also forms a large number of bubbles in the rotating vortex, which can increase the amplitude of water ripples, thus making it more conducive for the water carrying floating matter and other low-quality, low-oxygen water above the outlet zone 12 to automatically flow out of the outlet zone 12, accelerating water circulation. Of course, in practical applications, the angle can be any other angle that is conducive to gas-water mixing, depending on the working conditions.

[0034] Furthermore, the other end of the water inlet section 211 is bent and connected to one end of the oxygen mixing section 212, which is equipped with a check valve. The bottom bend of the water inlet section 211 connecting to the oxygen mixing section 212 prevents gas from the air inlet pipe 22 from entering the water inlet section 211, thus ensuring the water intake speed and oxygen supply. The check valve prevents water backflow, ensuring that the propulsive force of the gas lift can quickly introduce water into the tank 1.

[0035] Aquaculture systems typically have their breeding ponds located in bodies of water such as rivers, lakes, and fishponds, combined with... Figure 2The pool body 1 floats in the water area. The water inlet area 11 is located 15-25cm below the water surface, and the water outlet area 12 is located above the water surface. An ecological purification area is set up in the water area, and the water outlet area 12 is connected to the ecological purification area through the water outlet pipe 3.

[0036] An ecological purification zone is set up in the water area, containing aquatic plants and microorganisms. Low-quality, low-oxygen water from the outlet zone 1 can be discharged through the outlet pipe 3 to the ecological purification zone for purification and oxygenation, resulting in high-quality, high-oxygen water. It is important to note that the outlet pipe 3 needs to be long enough to discharge the low-quality, low-oxygen water as far as possible into the ecological purification zone. This ensures that the purification and oxygenation process in the ecological purification zone does not affect the water quality near the aquaculture pond, thus guaranteeing that the high-quality, high-oxygen water can automatically enter the inlet zone 11 and be introduced into the pond 1 via the inlet component 2. The inlet zone 11 is located 15-25 cm below the water surface. At this location, the oxygen content in the water is higher, allowing for control of the oxygen supply equipment's gas supply and reducing costs.

[0037] The inlet area 11 surrounds the pool body 1, and several inlets 111 are provided on the outer periphery of the inlet area 11. The outlet area 12 surrounds the pool body 1 and is located above the inlet area 11. At least one outlet 13 is provided on the side wall of the pool body 1 corresponding to the outlet area 12. Water fluctuations within the pool body 1 can cause the water level to be higher than the outlet 13. The interior of the inlet area 11 has a cavity structure to accommodate water introduced from the inlets 111. The evenly spaced inlets 111 ensure uniform water intake and pressure, preventing the pool body 1 from tilting due to uneven stress. Furthermore, the numerous small inlets 111 help to screen out larger floating objects that may be present in the water, ensuring the cleanliness of the incoming water.

[0038] The outlet zone 12 is located above the inlet zone 11, and it is situated on the outer side of the pool body 1, as shown below. Figure 1 The surrounding water outlet structure shown has several outlets 13 evenly spaced on the side wall of the pool body 1. The water level in the pool body 1 is higher than the outlets 13, so that water with low quality and low oxygen content can be automatically flowed from the outlets 13 to the water outlet area 12 by means of the liquid level difference, and then led to the ecological purification area through the water outlet pipe 3.

[0039] Or such as Figure 3As shown, a water outlet is located at the water surface at the center of the pool body 1. Several inlet holes 141 are provided on the side wall of the water outlet 14. The water outlet 14 is connected to the outlet 13 via a drain pipe 5. Water from the pool body 1 can enter the water outlet 14. Since the water outlet 14 is located at the water surface, it is higher than the outlet 13 and the water outlet area 12. Therefore, the water in the water outlet 14 can be discharged to the water outlet area 12 via the level difference through the drain pipe 5 and the outlet 13, and then led to the ecological purification area via the outlet pipe 3. The number of drain pipes 5 and outlets 13 is equal and their positions correspond one-to-one; their number is determined by the water output.

[0040] In addition, combined Figure 2 A cavity 15 is provided between the water inlet zone 11 and the water outlet zone 12. The cavity 15 is connected to an air inlet pipe 6 and an exhaust pipe 7. The connection point of the exhaust pipe 7 to the cavity 15 is higher than the connection point of the air inlet pipe 6 to the cavity 15. The cavity 15 provides sufficient buoyancy for the tank body 1, allowing it to float stably in the water, facilitating the fixed installation of the aquaculture tank and ensuring the stability of water circulation. Furthermore, reinforcing ribs can be installed within the cavity 15 to improve the structural strength of the aquaculture tank and prevent it from becoming too heavy, thus facilitating installation and transportation.

[0041] The cavity area 15 is a sealed environment, and water generally will not enter. However, as a precaution, if water does enter the cavity area 15, gas can be introduced into it through the air inlet pipe 6. This gas will then blow the water out through the exhaust pipe 7, ensuring stable buoyancy of the aquaculture pond. The gas can be air, and the air inlet pipe 6 can be directly connected to the oxygen supply pipe 4. The air inlet pipe 6 is equipped with a switch valve, which opens after water enters the cavity area 15, allowing the gas to blow the water out.

[0042] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
