[0002] An aerator is a machine commonly used in aquaculture. Its main function is to increase the oxygen content in the water to ensure that fish do not suffer from oxygen deficiency, while also inhibiting the growth of anaerobic bacteria and preventing water deterioration that could threaten the fish's living environment. However, existing aerators used in marine aquaculture have at least the following drawbacks: 1. Existing aerators have low oxygenation efficiency, affecting the aquaculture process; 2. Existing aerators do not easily agitate the water surface, hindering the mixing process between air and seawater. Therefore, we are introducing a new aerator for marine aquaculture.

[0025] Please see Figure 1-4 This utility model provides a technical solution:

[0026] An aerator for seawater aquaculture includes an aeration component 1. A fixing plate 2 is fixedly connected to the lower left and lower right parts of the aeration component 1. A winding wheel 3 is installed between the two fixing plates 2. A rope 4 is sleeved on the outer surface of the winding wheel 3. A counterweight ball 5 is fixedly connected to the lower end of the rope 4. Four fixing rods 6 are interlaced in a ring array on the outer surface of the aeration component 1. A round block 9 is fixedly connected to the side of the outer surface of the four fixing rods 6 near the aeration component 1. A buoyancy ball 8 is fixedly connected to the end of the four fixing rods 6 that does not contact the aeration component 1. A stirring component 7 is fixedly sleeved on the outer surface of the four fixing rods 6.

[0027] In this embodiment, the stirring assembly 7 includes a fixed frame 71. A waterproof motor 72 is fixedly connected to the front right end of the fixed frame 71. A support rod 73 is fixedly connected to the part of the output end of the waterproof motor 72 that passes through the fixed frame 71. Several flaps 74 are fixedly connected to the outer surface of the support rod 73 in a circular array. A circular groove 75 is opened on the rear right end of the fixed frame 71. The fixed frame 71 is fixedly sleeved with the fixed rod 6. The four support rods 73 are movably connected to the four fixed frames 71 through connecting shafts.

[0028] The above scheme involves setting up a stirring assembly 7 to stir the seawater. Four fixed frames 71 are fixedly connected to four fixed rods 6 to position the four stirring assemblies 7. Four waterproof motors 72 drive four support rods 73 to rotate, which in turn drives several flaps 74 on the outer surface of the four support rods 73 to stir the seawater. The stirring action of the flaps 74 significantly increases the contact area between the seawater and the air, effectively promoting the dissolution of oxygen in the air into the seawater and optimizing the oxygenation effect of the seawater.

[0029] In this embodiment, the oxygenation component 1 includes a support frame 11, with an oxygen tank 13 inserted through the upper end of the support frame 11. Four fixing blocks 14 are fixedly connected in a ring array on the outer surface of the support frame 11. A support pipe 12 is fixedly connected through the upper left part of the support frame 11. The support frame 11 is fixedly connected to two fixing plates 2. The support frame 11 includes a frame body 111, with a connecting frame 112 fixedly connected through the upper end of the frame body 111. Round pipes 113 are fixedly connected through the lower front and lower rear parts of the frame body 111. Nozzles 114 are fixedly connected through the lower ends of the two round pipes 113. The frame body 111 is fixedly connected to the four fixing blocks 14. The connecting frame 112 is fixedly connected through the oxygen tank 13. The four fixing blocks 14 are respectively sleeved with four fixing rods 6.

[0030] The above scheme involves: connecting the support pipe 12 to the external oxygen supply pipe to supply oxygen to the support frame 11 during use; connecting the four fixing blocks 14 to the four fixing rods 6 and fixing them with screws to position the four fixing rods 6, facilitating the four buoyancy balls 8 to support and float the entire aerator; connecting the oxygen tank 13 to the connecting frame 112 and fixing it with screws to connect the frame 111 and the oxygen tank 13 together; inserting both round pipes 113 underwater and supplying oxygen to the lower layer of seawater through two nozzles 114 to facilitate the oxygenation process in marine aquaculture; and having several air outlets on the two nozzles 114 to accelerate the mixing efficiency of oxygen and seawater.

[0031] It should be noted that this utility model is an aerator for seawater aquaculture. During use, firstly, the support pipe 12 is fixedly connected to the external oxygen supply pipe, establishing a stable external oxygen input channel to continuously supply oxygen to the support frame 11. Simultaneously, the oxygen tank 13 is fixed to the connecting frame 112 with screws, and the frame 111 is connected to the oxygen tank 13, providing a backup oxygen source for the aerator. Regarding the buoyancy system, four fixing blocks 14 are respectively sleeved with and screwed onto four fixing rods 6, precisely positioning the fixing rods 6. Together with four buoyancy balls 8, this provides reliable buoyancy support for the aerator, ensuring the equipment floats stably on the sea surface. In the oxygen delivery process, two round tubes 113 are inserted underwater, and oxygen is introduced into the lower layer of seawater through nozzles 114. The multiple air outlets on the nozzles 114 greatly improve the mixing efficiency of oxygen and seawater, allowing oxygen to quickly diffuse to the deeper parts of the water. The stirring component 7 is positioned by four fixed frames 71 connected to the fixed rods 6. Four waterproof motors 72 drive the support rods 73 to rotate, causing the flap 74 to stir the seawater. The rotation of the flap 74 significantly increases the contact area between seawater and air, strengthens the gas exchange process, promotes the rapid dissolution of oxygen in the air into the seawater, effectively improves the dissolved oxygen status of seawater, and creates a good living environment for marine aquaculture organisms.

[0032] 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. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
