Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an oxygenation device for aquaculture. Background Technology

[0002] With the continuous advancement of aquaculture technology, farmers are constantly increasing stocking density in order to improve yield and economic benefits. The high-density aquaculture environment accelerates the consumption of oxygen in the water. Natural water exchange and dissolved oxygen alone are insufficient to meet the needs of aquatic organisms. Therefore, aerators are needed to increase the oxygen content in the water to ensure the normal growth and survival of farmed organisms. Common aerators use a motor to drive an impeller to rotate, lifting the lower water layer to the surface while simultaneously drawing air into the water.

[0003] An existing authorized patent (CN220174203U) discloses an oxygenation device for aquaculture, relating to the field of aquaculture machinery technology. The device includes a main body with a base at its front end, floats at both ends, a protective canopy at the top of the base, and an oxygenation component installed at the upper left end of the base. In use, the base is first placed in the water requiring oxygenation. The floats keep the base afloat. A controller activates a control component, which drives an adjustment mechanism to move the base to a suitable position. The oxygenation component then oxygenates the water. When a fixed position is required, a first motor is activated, driving a winding drum to rotate clockwise or counterclockwise via a shaft. This stretches or retracts the wire rope. When the wire rope stretches, the anchor sinks to the bottom. Once the anchor touches the bottom, the wire rope is released, indicating whether the anchor has reached the bottom, thus achieving the desired fixation.

[0004] Regarding the aforementioned technologies, the existing aerators for aquaculture have the following drawbacks: different aquatic species have different requirements for dissolved oxygen in water. Oxygenation is usually achieved by stirring the water, but different aquatic species require different oxygen contents, necessitating the replacement of different stirring aerators, which increases aquaculture costs. Therefore, this utility model provides an aerator for aquaculture. Summary of the Invention

[0012] In summary, the technical effects and advantages of this utility model are as follows: In this invention, the protective components protect the equipment without affecting the oxygenation operation. Furthermore, the expansion components change the contact area between the impeller and the water, allowing more water to be propelled and a larger volume of water to come into contact with the air.

[0018] Example 1: Reference Figure 1-6 An aeration device for aquaculture, as shown, includes a fixed frame 2, which serves as the core mounting base, providing stable support for all components of the aerator and ensuring the overall structural integrity. Protective components are installed on its outer side. A support plate 4 is fixedly connected to the top of the fixed frame 2, supporting the transmission components such as the first deflection rod 7 and providing a mounting fulcrum for the transmission structure. The first deflection rod 7 is threaded through the interior of the support plate 4, transmitting power from the main bevel gear 5 to the rotating shaft 8. One end of the first deflection rod 7 is fixedly connected to the rotating shaft 8, which serves as the rotational core of the impeller 11, driving... The connecting plate 9 and the impeller 11 rotate synchronously. Multiple connecting plates 9 are fixedly connected to the side wall of the rotating shaft 8. These connecting plates 9 connect the rotating shaft 8 to the rotating housing 10, enabling power transmission from the rotating shaft 8 to the rotating housing 10. The rotating housing 10 provides a mounting platform for the impeller 11, ensuring stable assembly. The impeller 11 is fixedly connected to the outer side of the rotating housing 10. When the impeller 11 rotates, it agitates the water, increasing the contact area between the water and air, thus oxygenating the water. An expansion assembly is installed inside the impeller 11. A bevel gear 6 is fixedly connected to the other end of the first deflection rod 7. The bevel gear 6 and the main bevel gear... 5. To coordinate with the change of power transmission direction, the power is redirected and transmitted. The external bevel gear 6 meshes with the main bevel gear 5. The main bevel gear 5, as the power input component, receives power from the drive device and transmits it to the bevel gear 6. The protective components include a protective cover 22 installed on the outside of the fixed frame 2. The protective cover 22 protects the fixed frame 2 and the internal transmission components, preventing impurities in the water from impacting and damaging the components. A hatch is detachably connected to the outside of the protective cover 22. A floating plate 1 is provided on the side wall of the protective cover 22. The floating plate 1 provides buoyancy, allowing the aerator to float on the water surface and ensuring the stable operation of the aeration operation. Multiple filter holes 23 are opened on the side wall of the protective cover 22. The filter holes 23 allow water to flow while filtering large impurities in the water, preventing impurities from entering the protective cover 22. The expansion assembly includes a first extension plate 19 that is slidably connected to the inner wall of the impeller 11. The first extension plate 19 can extend outward to increase the effective working area of ​​the impeller 11, thereby improving the oxygenation range and efficiency. A slider 15 is fixedly connected to the side wall of the first extension plate 19. The slider 15 cooperates with the slide groove 14 to guide the sliding of the first extension plate 19. The slide groove 14 is provided inside the impeller 11. The slide groove 14 provides a sliding track for the slider 15, ensuring that the first extension plate 19 slides smoothly. The slider 15 is slidably connected to the slide groove 14.

[0019] Example 2: Reference Figure 1-5Based on the same concept as Embodiment 1 above, this embodiment further proposes that the impeller 11 has a first threaded hole 12 on its outer side for connecting external components to achieve structural fixation, and a second threaded hole 13 on the outer side of the other end of the impeller 11 for connecting with other components to enhance overall assembly stability; the top of the first extension plate 19 has a third threaded hole 16 for mounting connecting parts in conjunction with the first threaded hole 12, and bolts 17 are internally threaded to the first threaded hole 12 and the third threaded hole 16, and the impeller 11 is firmly fixed to the first extension plate 19 through threaded locking; the side wall of the first extension plate 19 rotates... The device is dynamically connected to a second deflection rod 18, which allows for angle adjustment of the second extension plate 21. The second extension plate 21 is fixedly connected to the side wall of the second deflection rod 18 to expand the structural bearing area and improve the support effect. A double-layer waterproof box 3 is fixedly connected inside the fixed frame 2 to effectively prevent external moisture from entering and protect the internal components. A motor 20 is installed inside the double-layer waterproof box 3 to provide power output for the operation of the device. The output end of the motor 20 passes through the double-layer waterproof box 3 to facilitate power transmission. The output end of the motor 20 is fixedly connected to one end of the main bevel gear 5, which can drive the main bevel gear 5 to rotate synchronously and realize the direction transmission of power.

[0020] The working principle of this device is as follows: Place the device in the water area requiring oxygenation, start the motor 20, which drives the main bevel gear 5 and bevel gear 6 to rotate the first deflection rod 7. The first deflection rod 7 drives the rotating shell 10 to rotate via the rotating shaft 8 and connecting plate 9. The impeller 11 on the rotating shell 10 contacts the water surface and rotates, stirring and aerating the water, drawing air into the water, and simultaneously raising the lower layer of water to the surface, allowing oxygen in the air to quickly integrate into the water. Open the hatch, and by unscrewing the bolt 17, the first extension plate 19 will extend from the impeller 11, increasing the contact area with the water and increasing the oxygen content. When the first extension plate 19 extends, the second extension plate 21 will also rotate, further increasing the contact area with the water. Thus, the stirring intensity and oxygenation level of the water can be adjusted according to actual needs.

[0021] Finally, it should be noted that the above description only modifies the technical solutions recorded in the examples, or makes equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
