[0002] In aquaculture, dissolved oxygen levels in the water are a key factor affecting the survival, growth, and yield of farmed organisms. Insufficient dissolved oxygen can easily lead to fish and shrimp surfacing for air, stunted growth, and even large-scale mortality, severely impacting aquaculture profitability. Therefore, oxygenation equipment, as one of the core pieces of equipment in aquaculture, directly affects the stability and economic viability of the industry.

[0041] Reference Figure 1-4 As shown, this utility model provides an aeration device for aquaculture, comprising:

[0042] The drive assembly 100 includes a gearbox 110 and a drive motor 120 mounted on the upper end of the gearbox 110. The gearbox 110 can effectively adjust the power output speed, reduce the impact of load fluctuations on power transmission, ensure the stable rotation of the conical water vane assembly 200, reduce the fluctuation of aeration efficiency caused by unstable power, and extend the service life of the equipment.

[0043] The conical water vane assembly 200 is connected and installed on the rotating shaft at the lower end of the gearbox 110. The conical water vane assembly 200 adopts a design with a conical body 210 and circumferentially distributed blades 230, which can effectively reduce resistance and prevent the speed from decreasing due to load.

[0044] The float assembly 300 includes a float 310 and a connecting frame 320 connected to the float 310. The other end of the connecting frame 320 is connected to and installed on the side of the gearbox 110.

[0045] In some embodiments of this utility model, reference is made to Figure 3-4 As shown, the gearbox 110 includes:

[0046] Side connection end 111 is located on the side of the gearbox 110 and is used to connect and install the mounting bracket 320. Bolt holes are provided on the side connection end 111.

[0047] Mounting plate 112 is fixedly welded to the rotating shaft at the lower end of gearbox 110 and is used to connect and mount conical water vane assembly 200.

[0048] The mounting plate 112 has bolt holes on its surface for connecting the conical water vane assembly 200, ensuring that power is stably transmitted to the conical water vane assembly 200.

[0049] In some embodiments of this utility model, reference is made to Figure 4 As shown, the conical water vane assembly 200 includes:

[0050] Conical body 210;

[0051] The connecting plate 220 is fixedly welded inside the cone-shaped bucket body 210 and is used to connect with the mounting plate 112. The surface of the connecting plate 220 is provided with bolt holes that match the mounting plate 112. The connecting plate 220 is rigidly connected to the mounting plate 112 by bolts, so that the cone-shaped bucket body 210 rotates synchronously with the shaft of the gearbox 110.

[0052] Blade 230 is distributed circumferentially along the outer side of cone body 210. Blade 230 is inclined at a certain angle to cone body 210. When rotating, it can strongly agitate the surface water.

[0053] Furthermore, the lower end of the cone-shaped body 210 is provided with a hollow opening 240.

[0054] When the cone-shaped body 210 rotates, the oxygen-rich surface water flows downward along the inner wall under the guidance of the cone-shaped body 210 and enters the deep water area through the perforated opening 240. At the same time, the oxygen-deficient deep water is replenished upward under the action of water pressure difference, forming a circulation and exchange between the upper and lower water layers, which greatly improves the dissolved oxygen diffusion efficiency.

[0055] In some embodiments of this utility model, reference is made to Figure 3-4 As shown, the float 310 includes:

[0056] Mounting end 311 is located at the upper end of float 310 and is used to connect to connecting bracket 320;

[0057] Rope hole 312 is located at the upper end of float 310 and is used for attaching rope.

[0058] The float 310 is made of high-density polyethylene, which has good buoyancy and corrosion resistance. Meanwhile, aquaculture personnel can secure the equipment to a predetermined position in the aquaculture pond by threading a rope through the rope hole 312, preventing the equipment from drifting with the water flow.

[0059] In some embodiments of this utility model, reference is made to Figure 3-4 As shown, the connecting bracket 320 includes:

[0060] The support rod 321 has one end connected to the mounting end 311. The mounting end 311 of the float 310 is provided with a socket. The support rod 321 is inserted into the socket and then fixed by bolts.

[0061] The connecting plate 322 is fixedly welded to the other end of the frame rod 321 and connected to the side connecting end 111 by bolts.

[0062] Depending on the shape of the aquaculture area, such as a rectangular pond, select the diagonal position, or a circular pond, select the area near the center. Thread the rope through the rope hole on the float 310, and fix the other end of the rope to the anchor pile or special fixing frame on the edge of the pond.

[0063] During operation, the drive motor 120 starts, and the power is regulated by the reduction gearbox 110 and transmitted to the water blade assembly 200 through the rotating shaft, driving the cone body 210 and the blades 230 to rotate. The blades 230 agitate the surface water to form water splashes, increasing the contact area with air to improve dissolved oxygen; at the same time, the cone body 210 guides the water flow to achieve water exchange between the upper and lower water layers, achieving the effect of lifting water and achieving the purpose of efficient oxygenation.

[0064] Clean regularly by using a high-pressure water gun to rinse the water jet assembly and float surface to remove algae and debris.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
