Description

Technical Field

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

[0002] Oxygenation devices play a vital role in aquaculture. They can not only effectively increase the dissolved oxygen concentration in the water, but also promote the self-purification of water quality by enhancing water circulation, reducing the accumulation of harmful substances such as ammonia nitrogen and nitrates, thereby providing a better growth environment for aquatic animals and ensuring their health.

[0003] However, existing oxygenation devices have some significant shortcomings in practical applications. First, the coverage of existing equipment is usually limited, especially in larger or irregularly shaped aquaculture ponds, where the oxygenation effect is often difficult to distribute evenly, resulting in insufficient oxygen supply in some areas of the water and affecting the overall aquaculture effect. At the same time, the aeration heads used for oxygen discharge are easily blocked by impurities, dirt or algae in the water during long-term use, leading to poor oxygen discharge, reduced oxygen dissolution efficiency, and may even cause the entire oxygenation equipment to malfunction or decrease in efficiency.

[0004] Based on this, we propose an oxygenation device for aquaculture rearing ponds to solve the aforementioned problems. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide an oxygenation device for aquaculture rearing ponds, which can solve the problems of limited coverage, uneven oxygen distribution, and poor oxygen discharge caused by easy clogging of aeration heads in existing oxygenation devices.

[0007] To solve the above technical problems, this utility model provides an oxygenation device for aquaculture rearing ponds, which adopts the following technical solution: it includes a support base, a protective component is installed on the top of the support base, oxygen supply pipes are connected around the outer wall of the support base, an oxygenation component is installed inside the support base, and an annular sealing groove is also provided around the top of the support base.

[0008] The oxygenation assembly includes multiple sets of oxygen supply branches, each with a fixed base installed at both ends, and several sets of oxygen aerators are equidistantly distributed on the top of each set of oxygen supply branches.

[0009] Optionally, the oxygen aerator includes an aeration head, the top of which is threadedly connected to an anti-clogging mesh cover, and the top of the anti-clogging mesh cover is also provided with an exhaust hood.

[0010] Optionally, the aeration head has an external thread for connection, and the top of the anti-clogging mesh cover is fitted with a fixing screw.

[0012] Optionally, the aeration head has a flow guiding cavity inside, and multiple sets of aeration holes are formed on the outside of the aeration head. The aeration holes and the flow guiding cavity are connected in a continuous manner.

[0013] Optionally, the protective component includes a connecting cover, a filter screen for impurities is provided in the middle of the connecting cover, and a sealing ring is provided around the bottom of the connecting cover. The sealing ring matches the annular sealing groove structure, and the sealing ring and the annular sealing groove are in a transition fit.

[0014] In summary, this utility model has at least one of the following beneficial effects:

[0015] 1. This solution involves installing oxygen supply pipes around the outer wall of the support base and adding an oxygenation component inside the base. This oxygenation component mainly consists of multiple sets of oxygen supply branch pipes, a fixed base, and oxygen aerators. It can effectively deliver oxygen to every corner of the aquaculture rearing pond, avoiding the problem of insufficient oxygen supply in certain areas due to uneven oxygen distribution. This ensures a balanced oxygen level in the entire aquaculture rearing pond, thereby guaranteeing the growth stability of aquatic products in the pond.

[0016] 2. This solution incorporates a protective component installed on top of the support base. This component mainly consists of a connecting cover, an impurity filter, and a sealing ring. Through the matching design of the sealing ring and the annular sealing groove, the protective component can be securely connected to the top of the support base. The impurity filter prevents impurities such as feed from entering the interior of the oxygenation component and avoids these impurities from adhering to the surface of the oxygen aerator. This effectively reduces the possibility of the aerator surface being blocked by impurities such as feed, thereby ensuring the stability of the oxygenation effect of the oxygenation device.

[0017] 3. The oxygen aerator in this solution consists of an aeration head, an anti-clogging mesh cover, and an exhaust hood. The anti-clogging mesh cover and the exhaust hood are located on top of the aeration head, which can provide secondary protection for the aeration holes and effectively prevent impurities such as feed from adhering to the surface of the aerator, thus avoiding clogging of the aeration holes. Through the above structure, the long-term stable operation of the oxygenation device in the aquaculture breeding pond is ensured, and the oxygenation efficiency and equipment operation reliability are improved.

The filter screen 19 can ensure that the oxygenation component 4 is in contact with the water in the pond, and can also prevent feed and other impurities from falling and adhering to the surface of the oxygen aerators 8. At the same time, it can also prevent the accumulation of substances on the surface of the oxygen aerators 8, which can cause blockage.

[0028] The oxygen aerator 8 includes an aeration head 9. The top of the aeration head 9 is threadedly connected to an anti-clogging mesh cover 10. The top of the anti-clogging mesh cover 10 is also provided with an exhaust hood 11. By adding the anti-clogging mesh cover 10 and the exhaust hood 11 to the top of the aeration head 9, a secondary protection can be provided for the aeration holes 17 used for oxygen discharge. This can prevent feed and other impurities from falling and adhering to the surface of the oxygen aerator 8 and causing blockage of the aeration holes 17. The aeration head 9 has an external thread 12 on its outer side. The top of the anti-clogging mesh cover 10 is equipped with a fixing screw head 13.
