Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a water outlet structure and an aquaculture pond. Background Technology

[0002] Fish, shrimp, crabs, and other aquatic products are typically raised in aquaculture ponds within an aquaculture system. Aquaculture requires oxygen and produces uneaten feed and excrement. Heavier waste settles and separates at 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 zone for aeration and oxygenation, resulting in high-quality, high-oxygen water that is then reintroduced into the ponds, thus achieving water circulation.

[0003] Currently, high-quality, high-oxygen water is typically introduced into aquaculture ponds via airlift. This involves installing an airlift water intake device on the outside of the pond to mix gas and water before introducing it into the pond, achieving micro-powered water intake and reducing energy consumption. However, airlift water intake causes the gas entering from the pond's sidewall to generate numerous air bubbles in the water, creating water ripples and causing floating debris to accumulate in the center of the pond. Existing aquaculture ponds generally use outlets on the sidewalls, with water being discharged from the perimeter via a power pump. This prevents floating debris from being discharged with the water to the purification zone, thus affecting the water quality within the pond and impacting aquaculture profitability. Utility Model Content

[0004] To address the aforementioned deficiencies in the existing technology, the purpose of this utility model is to provide a water outlet structure and aquaculture pond that enables water to exit from the center of the pond, thereby facilitating the discharge of floating debris along with the water, improving water quality, ensuring the growth rate and health of aquatic products, facilitating high-density aquaculture, and increasing aquaculture profits.

[0005] The first aspect of this utility model provides a water outlet structure, comprising:

[0006] A pond, which is filled with water used for aquaculture.

[0007] The water outlet assembly includes a water collection chamber and a drain pipe. The water collection chamber is located in the center of the pool and at the water surface. Several water inlet holes are opened on the side wall of the water collection chamber. The water collection chamber is connected to the outside of the pool through the drain pipe. The water outlet assembly is equipped with a power device or the water outlet level of the drain pipe is lower than the water level inside the pool.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] See Figure 1 This utility model provides a water outlet structure, including: a pool body 1 and a water outlet component 2. The pool body 1 contains water for aquaculture. The water outlet component 2 includes a water collection chamber 21 and a drain pipe 22. The water collection chamber 21 is located at the center of the pool body 1 and at the water surface. The side wall of the water collection chamber 21 has several water inlet holes 211. The water collection chamber 21 is connected to the outside of the pool body 1 through the drain pipe 22. The water outlet component 2 is equipped with a power device or the water outlet level of the drain pipe 22 is lower than the water level inside the pool body 1.

[0029] In aquaculture within pond 1, uneaten feed and excrement generated during the aquaculture process will accumulate. Heavier waste will settle and separate to the bottom of pond 1, while lighter floating debris will tend to accumulate in the middle area of ​​the water surface. A water collection chamber 21 is located at the center of pond 1 and above the water surface. Water with low quality and low oxygen content from the upper part of pond 1 can enter the water collection chamber 21 through the inlet 211, including floating debris in the middle area of ​​the water surface. Specifically, a power device such as a power pump is used to pump water through the inlet 211 into the water collection chamber 21, and then discharge it through the drain pipe 22. Alternatively, since the outlet water level of the drain pipe 22 is lower than the water level in pond 1, the water level difference between the pond 1 and the outlet water level of the drain pipe 22 allows water in pond 1 to automatically flow into the water collection chamber 21 through the inlet 211 and then be discharged through the drain pipe 22. In this way, water can be discharged from the middle of the aquaculture pond, which makes it easier to remove floating debris that has accumulated in the middle area of ​​the pond along with the water, thereby improving the water quality in the aquaculture pond, ensuring the growth rate and health of aquatic products, which is conducive to high-density aquaculture and increasing the aquaculture yield.

[0030] It is worth noting that the inlet hole 211 must not only allow water to enter the collection chamber 21, but its size should also allow floating objects to enter the collection chamber 21, so that the floating objects can be discharged from the aquaculture pond through the outlet component 2. The outlet component 2 can be fixedly installed in the pond body 1 by means of a fixing rod or other fixing structure to ensure stable water output.

[0031] Combination Figure 2 The side wall of the pool body 1 is provided with a water outlet 11. The water collection chamber 21 is connected to the water outlet 11 through a drain pipe 22. The position of the water outlet 11 is lower than the water level in the pool body 1. The position of the water outlet 11 is lower than the water level in the pool body 1, and there is a liquid level difference between the water level in the pool body 1 and the water outlet 11. This allows water in the pool body 1 to automatically flow into the water collection chamber 21 through the water inlet 211, realizing automatic water discharge, reducing energy consumption, and meeting the requirements of energy conservation and environmental protection.

[0032] One end of the drain pipe 22 is connected to the bottom of the water collection chamber 21. The drain pipe 22 extends downward from the bottom of the water collection chamber 21 and then bends to connect to the outlet 11. After the water in the pool 1 enters the water collection chamber 21 through the inlet hole 211, it automatically flows downward into the drain pipe 22, and then flows downward for a certain distance before turning to flow to the outlet 11. The drain pipe 22 is arranged in the lower part of the water collection chamber 21, which is conducive to the automatic flow of water under the action of liquid level difference and improves the water discharge effect.

[0033] The aquaculture system, including the aquaculture ponds, is installed within a body of water, such as rivers, lakes, seas, or fishponds. The pond body 1 floats in the water, with the outlet 11 positioned above the water level. An ecological purification zone is located within the pond, and the outlet 11 is connected to this zone via an outlet pipe 3. The ecological purification zone cultivates aquatic plants and microorganisms, which purify and oxygenate the water, enabling the recycling of aquaculture water, saving energy, reducing emissions, and lowering aquaculture costs.

[0034] It is worth noting that the outlet pipe 3 is set to be relatively long so that the water outlet of the outlet pipe 3 is far away from the breeding pond. This ensures that the water around the breeding pond is purified and oxygenated with high water quality and high oxygen content, while the water with low water quality and low oxygen content is discharged to the ecological purification zone at a distance for purification and oxygenation, thus having less impact on the water quality around the breeding pond.

[0035] Combination Figure 3 The outer periphery of the pool body 1 is provided with a water outlet cavity 12, which is set corresponding to the water outlet 11. The water outlet cavity 12 is connected to the ecological purification area through a water outlet pipe 3, which is set opposite to the water outlet 11. If the water outlet 11 is directly connected to the water outlet pipe 3, it will cause the pool body 1 to be unbalanced in force, making it difficult to float stably in the water, affecting water circulation and the stability of the aquaculture environment. In this utility model, the water outlet cavity 12 is set on the outer periphery of the pool body 1, and the water outlet cavity 12 is arranged around the pool body 1. The distance between the water outlet pipe 3 and the water outlet is preferably set opposite to each other, which allows the water to flow from the water outlet 11 into the water outlet cavity 12 and flow into the water outlet cavity 12 until it is evenly distributed, and then discharged into the ecological purification area through the water outlet pipe 3, thereby ensuring the stability of the pool body 1.

[0036] Combination Figure 4A water inlet chamber 13 is provided on the outer periphery of the pool body 1. The water inlet chamber 13 is connected to an air lift assembly 4, which includes a water inlet pipe 41 and an air inlet pipe 42. One end of the water inlet pipe 41 is connected to the water inlet chamber 13 and the air inlet pipe 42, and the other end of the water inlet pipe 41 is connected to the interior of the pool body 1. The water inlet of the aquaculture pool is achieved through the air lift assembly 4. The air lift assembly 4, through the connection structure of the water inlet pipe 41 and the air inlet pipe 42, that is, one end of the water inlet pipe 41 is connected to the water inlet chamber 13 and the air inlet pipe 42, and the other end of the water inlet pipe 41 is connected to the interior of the pool body 1, can use the air lift propulsion to introduce water and gas into the pool body 1 together. This not only realizes the micro-powered water introduction into the pool body 1, but also facilitates the uniform dissolution of oxygen in the water, thereby increasing the dissolved oxygen concentration in the water and achieving a high oxygen content in the water. At the same time, the gas generates a large number of bubbles in the water, which can push the water upward, so that the water automatically enters the water outlet assembly 2 and is discharged to the ecological purification zone through the water outlet pipe 3 for purification and oxygenation. Thus, when aquaculture ponds with this outlet structure are applied to aquaculture systems with water areas, they can achieve water circulation, water purification, and water oxygenation through micro-power, which can significantly reduce energy consumption, meet the requirements of energy conservation and environmental protection, and help reduce aquaculture costs.

[0037] It should be noted that the "gas" in this invention refers to air, thereby utilizing the oxygen in the air to oxygenate the water.

[0038] The water inlet pipe 41 has a U-shaped structure, and the air inlet pipe 42 is connected to the bottom of the water inlet pipe 41. The U-shaped structure of the water inlet pipe 41 can ensure that oxygen and water are fully mixed, thereby ensuring the uniformity of dissolved oxygen in the water flowing into the pool 1.

[0039] Multiple airlift components 4 are arranged at intervals around the outer periphery of the tank body 1. The air inlet pipes 42 of each airlift component 4 are connected to an air supply device via a main air inlet pipe 5, which surrounds the top of the tank body 1. The airlift components 4 are preferably evenly spaced to ensure uniform oxygen supply to the tank body 1, guaranteeing sufficient oxygen for all water within the tank and preventing the formation of oxygen-deficient areas. This promotes faster growth of aquatic organisms, ensures their health, and enables high-density aquaculture. The annular structure of the main air inlet pipe 5 further enhances the uniformity of dissolved oxygen in the water by evenly distributing oxygen to the multiple airlift components 4.

[0040] The inlet chamber 13 is positioned 15-25 cm below the water level of the water body, and several inlets 131 are provided on its side wall. An ecological purification zone is included in the water body, containing aquatic plants and microorganisms. Low-quality, low-oxygen water drawn from the outlet chamber 12 from the pool body 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. The inlet chamber 13 is located in a high-quality, high-oxygen environment within the water body, and is preferably 20 cm below the water surface. At this location, the oxygen content in the water is relatively high, allowing for control of the gas supply from the aeration equipment and reducing costs.

[0041] Based on the above structure, this utility model provides an aquaculture pond, which includes the aforementioned water outlet structure. The aquaculture pond floats in a water area, and an ecological purification zone is provided in the water area. Water from the drain pipe 22 flows into the ecological purification zone. The aquaculture pond can discharge low-quality, low-oxygen water containing floating matter to the ecological purification zone for purification and oxygenation through an intermediate water outlet. Then, high-quality, high-oxygen water is introduced into the aquaculture pond through a micro-powered airlift method, realizing the recycling of aquaculture water and ensuring the aquaculture environment. This results in good growth rate and health of aquatic products, which is conducive to high-density aquaculture and improves the aquaculture yield.

[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.
