[0054] The utility model discloses in a preferable embodiment can be further configured as: as shown in

[0055] The side baffles 32 are arranged in three equal groups of six, forming an isosceles right triangle. One side of each side baffle 32 is fixedly connected to the side of the inclined baffle 31, while the other two sides are fixedly connected to the lower frame 23. One end of the inclined baffle 31 is fixedly installed on the surface of the upper frame 22, and the other end is fixedly installed on the surface of the lower frame 23. This design allows the inclined baffles 31 to form an inclined flow guide surface. When the air intake and oxygenation component 4 introduces air into the land-based tank 1, the gas pushes the water flow along the inclined surface of the inclined baffles 31, thus achieving initial directional guidance of the water. The six side baffles 32 are divided into three equal groups, with each group of side baffles 32 cooperating with one group of inclined baffles 31 to form a complete flow guide structure. The side baffle 32 is arranged in an isosceles right triangle, with one side fixedly connected to the side of the inclined baffle 31, and the other two sides fixedly connected to the lower frame 23. This design not only enhances the structural strength of the flow guide baffle 3, but also allows the side baffle 32 to further guide the water flow, ensuring that the water flow can flow along a specific path under the push of the inclined baffle 31. During operation, the gas generated by the air intake oxygenation component 4 pushes the water flow in the land base tank 1. The water flow first flows along the inclined surface of the inclined baffle 31 and is guided by the inclined baffle 31. Subsequently, the water flow enters the flow guide channel formed by the inclined baffle 31 and the side baffle 32, and is further guided by the side baffle 32. Under the synergistic effect of the flow guide baffle 3, the water flow is guided to a specific direction, forming a circulating flow.

[0056] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 5 As shown; the angle between the inclined baffle 31 and the upper frame 22 is 45°. Each inclined baffle 31 corresponds to two side baffles 32. The area enclosed by the two side baffles 32 and one inclined baffle 31 is the water-pushing area. All three water-pushing areas are set in the same direction. The inclined baffle 31, as an important component of the guide baffle 3, is crucial for achieving the directional flow of water and the water-pushing effect. The angle between the inclined baffle 31 and the upper frame 22 is set at 45°, that is... Figure 1 The angle α is 45°. This design angle is chosen to maximize the use of the gas dynamics generated by the air intake and oxygenation component 4, so that the water flow can be pushed along the inclined surface of the inclined baffle 31 at an optimal angle. Each inclined baffle 31 corresponds to two side baffles 32, which together with the inclined baffle 31 form a specific area, namely the water pushing area. This water pushing area is... Figure 5The direction in which the water flow is pushed is indicated by arrow B, which clearly shows the direction in which the water flow is pushed, and since the three water pushing areas are arranged in the same direction, it ensures that the water in the land-based barrel 1 can form a unified and efficient flow pattern. In operation, the gas generated by the air inlet oxygenation assembly 4 pushes the water flow along the 45° inclined surface of the inclined baffle cloth 31. This flow is guided by the inclined baffle cloth 31 and is further guided into the water pushing area surrounded by the inclined baffle cloth 31 and the two side baffle cloths 32. In the water pushing area, the water flow is restricted and guided by the side baffle cloth 32, forming a directional and stable flow. Since the three water pushing areas are arranged in the same direction, the water in the entire land-based barrel 1 is effectively pushed and forms a circulating flow. This flow not only helps to reduce the accumulation of harmful substances in the water, but also promotes the uniform distribution of nutrients in the water. At the same time, since the water is in contact with air during the flow process, the dissolved oxygen content of the water is further increased, providing a more suitable environment for the growth of mandarin fish.
