Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to an aeration device suitable for large water bodies. Background Technology

[0002] In aquaculture, aeration equipment is a core component for maintaining dissolved oxygen in water and promoting nutrient cycling. It transfers oxygen from the air into the aerated water to supply the oxygen needed for aerobic organisms' metabolism. However, traditional aeration devices focus solely on gaseous oxygen supply, only performing basic oxygenation and failing to integrate organically with ecological aquaculture. This results in limited equipment functionality, low space utilization, complex structures, and high installation and maintenance costs. Summary of the Invention

When the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0029] like Figure 1 and Figure 2As shown, this embodiment of the invention provides an aeration device suitable for large water bodies, including: an aeration pipe group 1, an air intake device, and a net cage 5; multiple aeration pipe groups 1 are arranged side by side; the aeration pipe group 1 includes: an aeration pipe 11, a float pipe 12, and a vertical pipe 13; both ends of the aeration pipe 11 are respectively connected to the float pipe 12 through the vertical pipe 13; the aeration pipe 11 is installed in a deep water position below the liquid surface, and the float pipe 12 floats on the water surface; multiple evenly distributed aeration holes 1a are opened on the aeration pipe 11; the air intake device includes an air supply mechanism 21 and an air intake pipe 22; one end of the float pipe 12 is connected to the air supply mechanism 21 through the air intake pipe 22, and the other end of the float pipe 12 is a sealed end; the net cage 5 is a box structure formed by fishing nets, and the top of the net cage 5 is an open end; the net cage 5 surrounds two adjacent aeration pipe groups 1.

[0030] In this embodiment, the aeration pipe 11 is a flexible tube. The length of the aeration pipe 11 and the float pipe 12 can be designed to be 1-100m, and the number can be greater than or equal to 2, which is suitable for long-distance aeration over large water surfaces. The aeration holes 1a can be designed with a diameter of less than or equal to 1mm. The micropore design can generate microbubbles with a diameter of less than or equal to 1mm. Microbubbles have a large specific surface area, which enhances the mass transfer efficiency of oxygen molecules from the gas phase to the liquid phase. At the same time, microbubbles rise more slowly and have a longer residence time in the water, further promoting the efficient dissolution of oxygen.

[0031] Multiple aeration pipe groups 1 are arranged side by side, that is, multiple aeration pipes 11 are arranged horizontally below the liquid surface, and multiple float pipes 12 are arranged horizontally above the liquid surface. Figure 2 As shown, multiple aeration pipes 11 and floating pipes 12 can be designed as modular variable length specifications, such as 20m, 40m, 50m, 60m, 80m or 100m, etc., which can be freely combined according to the structural characteristics of different aeration tanks. On the one hand, the multi-specification length design can flexibly adapt to the contours of irregular tank shapes (such as heterogeneous ponds or multi-area partitioned water tanks), and achieve full coverage aeration through segmented combination. On the other hand, by adjusting the length of each section of pipe, the aeration blind zone formed at corners or partitions of traditional fixed-length aeration pipes 11 can be effectively eliminated, thereby ensuring the uniformity of dissolved oxygen in the entire water body.

[0032] The aeration pipe 11 can be made of thermoplastic polyurethane material. When installing and using it, the aeration pipe 11 is placed in the deep water area below the liquid surface, that is, close to the bottom 100 of the aeration tank, for example, at a height of 5-10cm from the bottom 100 of the tank. This can promote the growth of bacterial and algal flocs in the sludge at the bottom 100 of the tank, decompose organic matter by microorganisms, and prevent the production of anaerobic and harmful bacteria. It also reduces the release of harmful substances such as hydrogen sulfide and ammonia nitrogen, improves the water purification capacity, and prevents the discharge of tailwater.

[0033] The float tube 12 can be made of rigid polyvinyl chloride or high-density polyethylene. The float tube 12 has both aeration and buoyancy functions, so that the entire aeration tube group 1 is suspended in the water.

[0034] Both ends of the aeration pipe 11 are connected to the float pipe 12, and the float pipe 12 is connected to the air inlet pipe 22. The float pipe 12 can also be used as an air inlet unit to realize bidirectional air intake of the aeration pipe 11. When the length of the aeration pipe 11 reaches 50-100m, uniform aeration can still be maintained in the pipe.

[0035] The vertical pipe 13 connects the aeration pipe 11 and the float pipe 12, enabling bidirectional air intake through the aeration pipe 11 and resisting its upward buoyancy, allowing it to float stably in deep water. Counterweights 3 can be further installed on the vertical pipe 13 and the aeration pipe 11 to counteract buoyancy through their own weight. The counterweights 3 can be made of stainless steel or galvanized steel.

[0036] The riser 13 can be made of rigid pipe, and its material includes, but is not limited to, stainless steel, galvanized carbon steel, polyvinyl chloride, or polyethylene. The riser 13 can also be connected by a combination of rigid pipe and a flexible, extendable hose, where the hose is a steel wire hose. During installation and use, the aeration pipe 11 will be subjected to continuous upward stress. If only a rigid connection is used, stress concentration can easily lead to mechanical damage at the pipe joint. By adding a steel wire hose with elastic deformation capability between the rigid pipe and the aeration pipe 11, damage to the aeration pipe 11 caused by sudden stress changes can be avoided, improving the reliability and service life of the aeration pipe 11.

[0037] The net cage 5 is a pentahedral box structure with an open top, enclosed by fishing nets. Its four sides are formed by two aeration pipes 11 and two floating pipes 12, creating a stable three-dimensional frame. Each pair of aeration pipes 11 combined with one net cage 5 constitutes an independent aquaculture unit. Multiple units can be connected in parallel to form a large-scale aquaculture area, enabling group-based aquaculture management. This structure integrates aeration function with the aquaculture space in three dimensions. The aeration pipes 11 serve as oxygen supply devices and also support the net cage 5 structure, while the floating pipes 12 provide buoyancy and frame stability. This multi-functional integrated design is simple in structure and improves space utilization.

[0038] The aeration device for large water bodies provided in this embodiment of the invention combines multiple aeration pipe groups 1 and net cages 5 to form a large-scale aquaculture area, integrating aeration and aquaculture functions into one. The aeration pipe group 1 serves as an aeration element to uniformly release oxygen into the aquaculture water, and also serves as a supporting frame for the net cages 5 to construct the aquaculture space. This not only achieves coordinated operation of oxygenation and aquaculture, but also simplifies the overall structure and improves space utilization through structural reuse, effectively reducing installation and maintenance costs.

[0039] Furthermore, such as Figure 1As shown, the air inlet pipe 22 is equipped with a switch valve 23 to control the airflow. By adjusting the valve opening, the gas flow rate entering the aeration pipe 11 and the float pipe 12 can be precisely controlled. Furthermore, when multiple aquaculture units are connected in parallel, the airflow rate of each unit can be adjusted independently to adapt to the oxygen demand differences of different aquaculture species.

[0040] Furthermore, such as Figure 2 As shown, the aeration device also includes: a traction rope 4; both ends of the float pipe 12 are connected to the upper part of the aeration water body via the traction rope 4; both ends of the aeration pipe 11 are connected to the upper part of the aeration water body via the traction rope 4. The traction rope 4 can be made of steel wire rope. By anchoring both ends of the aeration pipe 11 and the float pipe 12 to the upper part of the aeration tank, a stable system is formed, effectively resisting the impact of water flow, wind and wave disturbance, and other external forces, preventing the device from drifting or overturning. At the same time, the traction rope 4 can be adjusted to control the suspension height of the aeration device, adapting to the needs of aquaculture at different water depths, and also facilitates installation, disassembly, and harvesting operations.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
