[0030] In order to make the purpose, technical solutions and advantages of the example embodiments of the present disclosure more clear and obvious, the example embodiments of the present disclosure will be further described in detail below with reference to the examples and drawings. The example embodiments and their descriptions are only used to explain the example embodiments of the present disclosure, and should not be considered as a limitation on the example embodiments of the present disclosure.

[0031] As shown in Figure 1 the present application, the water farming aeration equipment includes an aeration pipe 1, an aeration head 2, a cleaning brush 3, a support frame 4, a cyclone guide pipe 5 and a pressure regulator 6. These components work together to improve the efficiency and reliability of the equipment in complex water environments, and prevent the influence of biological attachments on the surface of the aeration head 2.

[0032] ​​​​The water culture aeration equipment adopts a high-efficiency aeration pipe 1 to transport gas. One end of the aeration pipe 1 is connected to a gas source, and the other end is in communication with an aeration head 2 located at a terminal position of the aeration system, to ensure that sufficient gas is stably transmitted to the aeration head 2 for diffusion treatment. In order to make the oxygen entering the water more widely and uniformly dispersed, a cyclone guide pipe 5 is installed at the end of the aeration pipe 1; by adjusting the state of the gas before entering the water flow to make it rotate, this vortex effect can make the gas be more delicate, so as to achieve higher mixing effect.

[0033] The aeration head 2 has a plurality of micro-pore array structures, and the micro-pores on the aeration head 2 are finely processed to form a layout of gradually changing pore diameters. Such a structure ensures that the gas can overflow from larger to smaller pores under different pressures, greatly promoting the diversity and efficiency of bubble formation, thereby improving the oxygen utilization rate and enhancing the water quality improvement ability. Specifically, the pore diameters of the micro-pores on the aeration head 2 gradually decrease along the gas flow direction.

[0034] In view of the risk of blockage of the aeration head 2 during long-term operation, an automatic cleaning device is used in conjunction, i.e. a cleaning brush 3 made of elastic bristles is fixedly assembled in the space around the outside of the aeration head 2, and can automatically remove various accumulated dirt or sediments on it under the impact of vibration or water, effectively solving the problems caused by long-term operation in complex water environment. Specifically, for example, the cleaning brush 3 can be sleeved on the outside of the aeration head 2, and a gap is provided between the two, so that the aeration head 2 can move on it to clean the aeration head 2 under the vibration generated during aeration.

[0035] In addition, in order to stabilize the positional relationship of the above-mentioned components and the overall shape, the entire system further includes a support frame 4 made of corrosion-resistant metal or other suitable materials, which provides a solid and reliable support platform for other parts, so that the entire device can be accurately placed inside the predetermined area and does not affect the performance of other functions.

[0036] In order to ensure that the amount of air entering the pipeline is moderate, a precision pressure regulator 6 is additionally provided near the source to monitor and adjust the stability fluctuation within the input flow size range, which avoids waste caused by overpressure of the gas and ensures safety during work.

[0037] As Figure 2As shown, in one embodiment, the aeration pipe 1 of the present application's aquaculture aeration equipment is connected to a gas source connector 7 at one end and connected to the aeration head 2 through a cyclone guide pipe 5 at the other end. The gas source connector 7 is a quick connector, which is convenient for disassembly and maintenance. This structural design ensures the ease of use and flexibility of the equipment, especially suitable for aquaculture scenarios that require frequent operation. The aeration pipe 1 is used to deliver compressed air from the gas source to the bottom of the breeding pond, and its installation position is usually close to the water surface or fixed at the bottom of the water to ensure that air can be uniformly distributed to the entire water area. The aeration head 2 is located at the end of the aeration pipe 1 and is usually placed at a lower position in the water. Through the use of the cyclone guide pipe 5, effective mixing of gas and water is achieved. The cyclone guide pipe 5 is responsible for guiding and distributing the compressed air delivered by the gas source connector 7, so that the gas can have a better dispersion effect when entering the breeding environment.

[0038] Specifically, in one embodiment, the quick connector serves as the gas source connector 7 and is installed at one end of the aeration pipe 1, directly connected to the air pump or other external gas source. This quick connector has a locking device that can be quickly disassembled without tools. For example, the user only needs to press the buckle or rotate the locking part on the quick connector to easily connect or disconnect the gas source, greatly improving the efficiency of maintenance and replacement work. At the same time, the other end is connected to the cyclone guide pipe 5 and the aeration head 2 through threads, flanges or other reliable connection forms, ensuring that air is smoothly and leak-free delivered to the target position, so that the equipment remains in a high-efficiency and stable working state throughout its service life.

[0039] In one embodiment, referring to Figure 4 The aeration head 2 of the present application's aquaculture aeration equipment is surrounded by multiple layers of filter screens 8. The key to this structural design is to filter impurities layer by layer to avoid micro-pore blockage. The aeration head 2 is internally arranged with multiple layers of filter screens 8, and the pore size of each layer of filter screens 8 gradually decreases from the outside to the inside, so that larger particle impurities can be effectively intercepted by the outermost first layer of filter screens 8, and smaller particle impurities can be filtered out by the inner layers of filter screens 8 with smaller pore sizes, thereby gradually removing suspended impurities of various sizes in the water.

[0040] The material of the multiple layers of filter screens 8 is stainless steel, which ensures that the entire filtration system has good corrosion resistance and is suitable for harsh environments that work underwater for a long time, maintaining stable performance. In addition, in order to facilitate later maintenance and cleaning, the filter screens 8 are designed to be detachable. In this way, users can easily remove and clean or replace the filter screens 8, ensuring that the system is always in optimal working condition, while reducing the problem of efficiency decline caused by dirt accumulation. Each layer of filter screens 8 is tightly connected, ensuring efficient interception without water leakage, thereby optimizing the effect of gas entering the water quality.

[0041] For example, during actual installation, the first layer of filter screen 8 can be assembled at the inlet of the aeration device as the outermost layer, and successively, finer filter screens 8 are stacked and placed closer to the center of the aeration head 2. Specifically, the connection between each layer is fixed by a lock or other means, which not only ensures stability but also facilitates quick assembly and disassembly during routine maintenance, thereby not affecting the normal operation of the entire device and meeting the needs of different application scenarios.

[0042] In one embodiment, the cleaning brush 3 of the aquaculture aeration device of the present application is mainly composed of a fixed seat 9 and elastic bristles. The fixed seat 9 is installed on the aeration head 2, ensuring a stable connection between the cleaning brush 3 and the aeration head 2. The elastic bristles are arranged in a radial pattern, which can completely cover all the micro-holes of the aeration head 2, effectively removing dirt in the micro-holes. This arrangement ensures that each part of the aeration head 2 can be uniformly and effectively cleaned even after a long period of operation. In addition, in order to better adapt to cleaning needs in different environments, an adjusting bolt 10 is provided on the fixed seat 9. By adjusting the bolt 10, the length and density of the elastic bristles can be flexibly adjusted, so that the cleaning brush 3 can provide the best cleaning effect under different working conditions. The fixed seat 9 and the aeration head 2 can be fixed by screws or buckles to facilitate maintenance and replacement.

[0043] Specifically, as shown in Figure 3 , the adjusting bolt 10 not only serves to fix the cleaning brush 3, but also changes its position and angle by being screwed in or out. For example, tightening the bolt can compress the spring assembly, thereby reducing the effective length of the bristles; loosening the bolt will increase the spring force, thereby lengthening the bristles, making them more fluffy and loose. In this way, users can choose appropriate length and density settings according to actual use conditions, such as the amount of silt in the water, water temperature, etc., to achieve more precise and effective cleaning control.

[0044] In one embodiment, referring back to Figure 1 , the support frame 4 of the aquaculture aeration device of the present application is composed of several support rods 11. These support rods 11 are designed with a telescopic structure, allowing the device to flexibly adjust the length according to different needs in actual applications. By adjusting the length of the support rods 11, it can adapt to aeration heads 2 of different diameters and sizes, and ensure their stability and precise installation position. This design improves the applicability of the entire device in different application scenarios. In addition, the bottom end of each support rod 11 is provided with a fixed claw 12, which is made of rubber material and can be firmly adsorbed on the bottom or wall of the pool, further enhancing the stability of the support frame 4. The choice of rubber material not only provides good grip, but also protects the pool body from being scratched by hard materials.

[0045] Specifically, the main function of the support frame 4 is to provide a stable support for the aeration head 2, avoiding the device from shaking or tilting due to external water flow and other factors, thereby affecting the aeration effect. The support rod 11 of the support frame 4 has the characteristic of adjustable height, which can be easily operated to adapt and fix aeration heads 2 of various sizes. The telescopic structure design ensures that the device has wide compatibility and good stability.

[0046] For example, when it is necessary to replace aeration heads 2 of different types or sizes, the user can stretch or compress the support rod 11 to the appropriate length, so that the support frame 4 accurately fixes the aeration head 2. At this time, the fixed claws 12 at the bottom will be tightly adsorbed to the surface of the pool bottom or wall, preventing any possible displacement. In this way, the device can maintain a stable working state in various pool environments.

[0047] In one embodiment, as shown in Figure 5 The design of the aquatic breeding aeration device of the present application makes the internal structure of the cyclone conduit 5 unique. Specifically, the inner wall of the cyclone conduit 5 is provided with a plurality of spiral flow guide grooves 13, which are arranged along the direction of gas flow. Each spiral flow guide groove 13 is continuously and regularly distributed in a spiral shape on the inner wall, so that the gas entering the cyclone conduit 5 rotates and forms a vortex motion in the process of advancing due to the influence of the groove body. Through such an arrangement, it can ensure that the gas is distributed in the entire conduit internal space in a more uniform manner, and effectively promote the dispersion and flow of the gas flow.

[0048] To achieve this effect, various means are adopted to optimize the structure setting and installation position selection during design. The spiral flow guide grooves 13 are tightly fitted to the inner surface of the cyclone conduit 5, and there is no obvious gap between them, which ensures the consistency and integrity of the flow guide groove shape from the inlet end to the outlet end. In addition, during the manufacturing process, the selection of suitable materials and the accurate machining of the specified spiral angle and pitch parameters is the key.

[0049] For example, a suitable metal or plastic material can be selected to make a cyclone conduit 5 with a certain rigidity, and a number of regularly arranged spiral grooves, i.e. spiral flow guide grooves 13, are machined on the inner surface of the conduit by mold or machining method, ensuring that the depth, width and pitch of these grooves meet the predetermined design requirements. Then the pipeline is assembled to the corresponding position of the aeration system to complete the assembly process. In this scheme, every detail is fully considered to ensure the function realization and structural stability.

[0050] In one embodiment, the outlet of the cyclone conduit 5 of the present application's aquaculture aeration device is provided with a deflector 14. The deflector 14 is installed between the cyclone conduit 5 and the aeration head 2, and is located above the aeration head 2. This design further guides the gas flow ejected from the cyclone conduit 5 accurately into the aeration head 2, thereby optimizing the entire aeration process.

[0051] The deflector 14, as a special guiding device, reduces the turbulent effect that may occur when the gas flow transitions from the cyclone conduit 5 to the aeration head 2, avoiding unnecessary bubble chaos, and making the formation of bubbles more regular and stable. Since the effectiveness of the aeration operation is directly affected by the entering gas flow pattern, by properly setting the deflector 14, the gas-liquid contact efficiency can be improved, ensuring that more oxygen is uniformly dissolved in the water body. In addition, the optimized flow state also improves the stability and controllability of the overall system operation.

[0052] In one embodiment, specifically, the deflector 14 is made of a lightweight but tough material, ensuring its structural strength while not affecting the normal operation and maintenance convenience of the device. For example, plastic or stainless steel can be used. The installation method is usually to pre-design suitable fixed interface positions or support structures on the edge of the outlet of the cyclone conduit 5, and then install the deflector 14 directly into these pre-set positions. In this way, it is ensured that the deflector 14 is stably located between the cyclone conduit 5 and the aeration head 2, and effectively plays a role in guiding the gas flow.

[0053] In one embodiment, one of the features of the present application's aquaculture aeration device is its pressure regulation system. This system includes a pressure gauge 15 and a pressure regulating valve 16, designed to accurately monitor and adjust the gas flow to maintain the stability of the aeration process. The setting of the pressure regulation system can ensure that the gas entering the aeration system always remains within the required pressure range, which is crucial for providing stable and efficient water oxygenation conditions. In specific applications, by monitoring and adjusting the pressure in real time, optimal operating parameters can be maintained under different working conditions, thereby meeting the needs of different stages of aquaculture.

[0054] Specifically, the pressure regulator 6 of the aeration device is installed on the gas supply pipeline and is located close to the air inlet. This installation position allows the gas introduced from the outside to be monitored and adjusted in pressure in the first place, effectively avoiding the instability of the gas flow caused by external factors. The pressure gauge 15 is installed at the front end of the pressure regulating valve 16, and the two are connected through a standard connector to form a compact and easy-to-control pressure management unit. Among them, the pressure gauge 15 is used as an information feedback component to display the actual gas pressure value inside the pipeline, and the pressure regulating valve 16 is responsible for adjusting the gas pressure level entering the system according to the set or human instruction. The design of the pressure regulating valve 16 supports manual operation and electric drive mode, which is convenient for flexible use in various environmental conditions to meet the requirements of diversified application scenarios.

[0055] For example, when using the manual mode, the opening degree can be directly changed by rotating the operating handle on the pressure regulating valve 16; if the electric control is selected, the signal is sent to the motor drive device through the external control system, and the opening angle of the valve is automatically adjusted to ensure that the pressure is maintained within the preset interval. The above structure configuration and technical details fully demonstrate the specific way to achieve this function and its feasibility in actual application.

[0056] In one embodiment, the water aquaculture aeration device of the present application is characterized in that the diameter of the aeration head 2 is smaller than the diameter of the cyclone guide pipe 5. By reasonably designing the size relationship between the aeration head 2 and the cyclone guide pipe 5, it is ensured that the gas can maintain sufficient pressure during transmission. The core components of the device mainly include the aeration head 2 and the cyclone guide pipe 5, both of which are important components of the aeration system. The aeration head 2 is used to release the gas into the water body in the form of small bubbles, while the cyclone guide pipe 5 plays a role in guiding the gas flow and enhancing the gas mixing effect. In order to ensure the pressure stability during gas transmission, the inner diameter of the aeration head 2 is set to be significantly smaller than that of the cyclone guide pipe 5, so as to prevent excessive pressure drop during the conversion of the gas flow.

[0057] Specifically, in terms of installation position and structure, the cyclone guide pipe 5 is located on one side of the system air inlet, and its large inner diameter is beneficial to receiving high-flow gas input from the external high-pressure gas source. The aeration head 2 is arranged at the end of the system or close to the bottom of the water body, and through the design of the small opening, the small bubbles can be distributed more effectively. The small inner diameter of the aeration head 2 increases the speed of the gas flow transferred from the cyclone guide pipe 5, while reducing unnecessary resistance loss. The close connection between the two ensures smooth gas flow, optimizing the efficiency and performance of the entire system.

[0058] For example, the appropriate material and manufacturing process can be selected to precisely control the size of the two key components. Select high-strength, corrosion-resistant plastic or metal alloy as the main structure of the rotating flow pipe 5 and aeration head 2, and use high-precision mold and lathe equipment for fine processing during processing to achieve the required geometric size specifications. In addition, the two parts can be firmly and tightly connected together in the form of threads or quick couplings to maintain stable operation.

[0059] In actual operation, when the device is in use, the user connects one end of the aeration pipe 1 to a gas supply source (such as an air compressor or pure oxygen equipment), ensuring that enough gas can be transmitted to the core part of the device. As the gas passes through the aeration pipe 1, the pressure regulator 6 installed on it begins to work, automatically adjusting the pressure of the gas according to the preset parameters to ensure that the gas can enter the next component at a stable flow rate.

[0060] Next, the stably regulated gas is delivered to the rotating flow pipe 5 located between the aeration pipe 1 and the aeration head 2. In this process, the unique structure of the rotating flow pipe 5 causes the gas flow to rotate and advance downstream in the form of a vortex. This spiral pneumatic effect not only effectively increases the turbulent energy of the gas in the entire pipeline, but also makes the gas flow more dispersed and uniform when it attacks the aeration head 2. When the gas leaves the rotating flow pipe 5 and reaches the aeration head 2, due to the special aperture gradient design of the device's micropores, it can efficiently divide large gas packets into a larger number of small bubbles. This process greatly increases the contact surface area between oxygen or other beneficial gases and the surrounding water, accelerating the dissolution rate of the gas from the air into the water. At the same time, the support frame 4 that holds the aeration head 2 keeps the entire aeration system stable and in the correct position to avoid any device deviation or shaking caused by external impact, ensuring the smooth operation of the aeration work.

[0061] In the long-term operation process, due to the problem of a large number of microorganisms and organic matter adhering to the surface of the aeration in the aquaculture environment, the presence of the cleaning brush 3 is particularly important. The device is equipped with bristles made of elastic and corrosion-resistant and antibacterial materials, which are tightly attached to the surface of the aeration head 2. When the device is working, these bristles will actively rub the small gaps and hole edges of the aeration head 2 under the action of water flow vibration and water flow impact force, timely cleaning away harmful objects such as impurities and biofilms that have just begun to grow or are trying to firmly adhere to it. Such a mechanism not only maintains the effective open state of the micropores, but also prolongs the overall life of the device.

[0062] The above specific embodiments further explain the purposes, technical solutions and beneficial effects of the embodiments of the present disclosure. It should be understood that the above description is only a specific embodiment of the present disclosure and is not used to limit the protection scope of the present disclosure.
