Description

Technical Field

[0001] This utility model relates to the field of factory farming technology, and in particular to a water-pushing and oxygenating device for factory farming ponds. Background Technology

[0002] In the field of factory farming, water aeration devices are the core equipment for realizing water circulation and maintaining a suitable dissolved oxygen concentration, which directly affects the growth rate, health status and stocking density of farmed organisms.

[0003] Existing aeration devices suffer from low dissolved oxygen efficiency and uneven oxygen distribution. Traditional impeller and paddlewheel aerators generate bubbles through mechanical stirring. These bubbles are large in diameter, resulting in a small gas-liquid contact area and low dissolved oxygen efficiency. Many bubbles dissipate before dissolving. Furthermore, these devices are often fixed to the bottom or edge of the pond, limiting their water-pushing range and leading to significant differences in dissolved oxygen levels between the inner and outer layers, as well as between the upper and lower layers. This can cause localized insufficient dissolved oxygen, resulting in organisms surfacing and dying. In addition, existing devices lack real-time monitoring and automatic control functions, requiring regular manual water quality checks and adjustments to the operating status. Monitoring is often delayed, and control precision relies on experience, easily leading to problems such as excessive dissolved oxygen consuming energy or insufficient dissolved oxygen affecting growth, resulting in low work efficiency.

[0004] Therefore, a water-pushing and oxygenation device for factory-style aquaculture ponds is proposed. Utility Model Content

This invention uses a water quality monitoring component to detect the dissolved oxygen content in water in real time and transmits the data to an intelligent control system. When the dissolved oxygen is lower than the set value, the intelligent control system adjusts the rotation speed of the drive component and changes the water pushing speed to accelerate water circulation. At the same time, the angle adjustment component adjusts the water entry angle of the propeller blade assembly to adapt to the oxygenation needs of water at different depths. The water quality monitoring and control closed loop can be completed without manual intervention, avoiding situations of excessive or insufficient dissolved oxygen. This ensures a suitable growth environment for aquaculture organisms, reduces energy waste, improves the intelligence and accuracy of water quality management, and increases work efficiency. In this invention, the annular float can float on the water surface without being fixed to the bottom of the pond. With the help of the angle adjustment component to adjust the direction of the propeller blade assembly, it can be adapted to aquaculture ponds of different shapes and sizes, ensuring that water circulation and oxygenation cover the entire aquaculture area and improving oxygenation efficiency.

[0018] 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.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1-5 This utility model provides a water-pushing and oxygenating device for factory-scale aquaculture ponds, comprising: An annular float 1, on which a bracket 2 is mounted; Water quality monitoring component, the water quality monitoring component is installed on the annular float 1, and the detection end of the water quality monitoring component extends into the water body; The intelligent control system is installed on bracket 2; The power system includes an angle adjustment component and a drive component. The angle adjustment component is mounted on the bracket 2, and the drive component is mounted on the output end of the angle adjustment component. Propeller blade assembly 3 is installed at the output end of the drive assembly and extends into the water body through the central through hole of the annular float 1. The oxygenation mechanism includes a venturi tube 4 and a telescopic air inlet pipe 5; one end of the venturi tube 4 is sleeved outside the propeller blade assembly, and the other end extends into the water body; one end of the telescopic air inlet pipe 5 is installed on the bracket 2, and the other end is connected to the middle section of the venturi tube 4. Among them, the power system and water quality monitoring components are electrically connected to the intelligent control system, and the Venturi tube 4 has several micropores 45 at one end near the propeller blade assembly 3. With this configuration, the present invention utilizes the Venturi effect to achieve efficient water-air mixing by combining the propeller blade assembly 3 with the Venturi tube 4 and micropores 45. When the propeller blade assembly 3 rotates, it generates negative pressure, which draws in air through the telescopic air intake pipe 5. After entering through the middle section of the Venturi tube 4, the air is cut by the rotating airflow of the propeller blade assembly 3 and then refined into tiny bubbles through several micropores 45 at the end of the Venturi tube 4, greatly increasing the gas-liquid contact area. At the same time, the water-pushing action of the propeller blade assembly 3 drives the bubbles to diffuse evenly in the water, avoiding local bubble accumulation, and allowing dissolved oxygen to quickly penetrate to all areas of the aquaculture pond. This effectively solves the problems of large bubbles and uneven dissolved oxygen in traditional aeration systems, achieving efficient water-air mixing and significantly improving the dissolved oxygen efficiency of the water. This invention uses a water quality monitoring component to detect the dissolved oxygen content in water in real time and transmits the data to an intelligent control system. When the dissolved oxygen is lower than the set value, the intelligent control system adjusts the rotation speed of the drive component and changes the water pushing speed to accelerate water circulation. At the same time, the angle adjustment component adjusts the water entry angle of the propeller blade assembly 3 to adapt to the oxygenation needs of water at different depths. The water quality monitoring and control closed loop can be completed without manual intervention, avoiding situations of excessive or insufficient dissolved oxygen. This ensures a suitable growth environment for aquaculture organisms, reduces energy waste, improves the intelligence and accuracy of water quality management, and increases work efficiency. In this invention, the annular float 1 can float on the water surface without being fixed to the bottom of the pool. With the help of the angle adjustment component to adjust the direction of the propeller blade assembly 3, it can be adapted to aquaculture ponds of different shapes and sizes, ensuring that water circulation and oxygenation cover the entire aquaculture area and improving oxygenation efficiency.

[0021] Further optimization of the solution includes the following angle adjustment components: Mounting base 6, mounting base 6 is mounted on bracket 2; A rotating shaft 7 is mounted on the bottom of a mounting base 6 via a bearing housing; a motor base is mounted on one end of the rotating shaft 7, and a drive disk 8 is mounted on the other end; the drive assembly is mounted on the motor base. Electric actuator 9 is rotatably connected to mounting base 6, and the telescopic end of electric actuator 9 is rotatably connected to drive disk 8; The limiting slide rail 10 is mounted on the mounting base 6. Limiting posts 12 are installed on both sides of the limiting slide rail 10. A first slider is slidably connected to the limiting slide rail 10. A connecting plate 11 is mounted on the first slider, and a long groove is provided on the connecting plate 11. Among them, the end of the drive disk 8 away from the electric push rod 9 is rotatably connected to the second slider, and the second slider is slidably connected to the elongated groove; the electric push rod 9 is electrically connected to the intelligent control system; the intelligent control system adopts a PLC or a single-chip microcomputer; When the intelligent control system issues an angle adjustment command, the telescopic end of the electric actuator 9 moves, pushing or pulling the drive disc 8, which in turn drives the rotating shaft 7 to rotate. The second slider slides in the long groove of the connecting plate 11. At the same time, the connecting plate 11 moves along the limiting slide rail 10 through the first slider. The limiting posts 12 on both sides of the limiting slide rail 10 can limit the sliding range of the first slider, accurately control the rotation angle of the rotating shaft 7, and thus adjust the water depth of the drive assembly and the propeller blade assembly 3 to adapt to the water depth requirements of different areas of the aquaculture pond, ensuring that each water layer can be efficiently oxygenated.

[0022] The scheme is further optimized. The drive assembly includes a drive motor 13 mounted on a motor mount. The drive motor 13 is electrically connected to the intelligent control system. The output shaft of the drive motor 13 is equipped with a drive shaft. The propeller blade assembly 3 is mounted on the end of the drive shaft. The drive shaft is fitted with a first sleeve 14. One end of the venturi tube 4 is fixedly connected to the outer wall of the first sleeve 14. When the drive motor 13 starts, the output shaft drives the drive shaft and the propeller blade assembly 3 installed at the end of the drive shaft to rotate at high speed, generating water propulsion and a negative pressure environment; the first sleeve 14 outside the drive shaft is fixed to one end of the venturi tube 4, which can fix the relative position of the venturi tube 4 and the propeller blade assembly 3, prevent the venturi tube 4 from shifting when the propeller blade assembly 3 rotates, and ensure that the Venturi effect is stably exerted.

[0023] When the water quality monitoring component detects that the dissolved oxygen level is low, the intelligent control system increases the speed of the drive motor 13, accelerates the rotation of the propeller blade assembly 3, enhances the water pushing force and negative pressure suction, thereby increasing the aeration volume and rapidly improving the dissolved oxygen level of the water.

[0024] Further optimization of the scheme: the water quality monitoring component includes a water quality monitoring sensor 15 installed on the annular float 1. The water quality monitoring sensor 15 is electrically connected to the intelligent control system. The probe of the water quality monitoring sensor 15 extends into the water body. The water quality monitoring sensor 15 is a dissolved oxygen sensor, used to detect the dissolved oxygen content in the water body in real time.

[0026] The design is further optimized by extending the bottom of the second air intake pipe into the inner cavity of the venturi tube 4, and the bottom of the second air intake pipe is set as an angled opening. The angled opening can guide the air to blend more smoothly into the high-speed water flow and be fully cut and dispersed by the propeller blade assembly 3, so as to avoid the formation of air clumps in the venturi tube 4, thereby improving the mixing efficiency of air and water and further increasing the dissolved oxygen rate.

[0027] Further optimization of the scheme: the Venturi tube 4 includes a first large diameter section 41, a second large diameter section 43, and a small diameter section 42. The two ends of the small diameter section 42 are fixedly connected to the first large diameter section 41 and the second large diameter section 43, respectively. A second sleeve 44 is installed at the end of the first large diameter section 41 away from the small diameter section 42. Several micro-holes 45 are opened on the second sleeve 44. An exhaust port 46 is installed at the end of the second large diameter section 43 away from the small diameter section 42. The bottom of the second intake pipe extends into the inner cavity of the small diameter section 42. One end of the second sleeve 44 is fixedly installed outside the first sleeve 14. The second sleeve 44 is sleeved outside the propeller blade assembly 3.

[0028] Further optimization of the scheme: a photovoltaic panel 16 is installed on the top of the bracket 2. The photovoltaic panel 16 can absorb solar energy and convert solar energy into electrical energy (DC or AC) through a photovoltaic inverter to power the device's intelligent control system, electric push rod 9, drive motor 13 and other electrical components.
