[0002] Aerator is a machine commonly used in fishery farming. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be deprived of oxygen. It can also inhibit the growth of anaerobic bacteria in the water and prevent the deterioration of the pond water and threaten the living environment of the fish. The aerators we use now are basically mechanical aerators. What is mechanical aerator? It is to use mechanical agitation or input air or oxygen (factory oxygen generator) into the water body to allow oxygen in the air or direct oxygen to dissolve into the water and become dissolved oxygen. Generally, the factors that affect the efficiency of mechanical aerator include the contact area between water and air.

[0003] The existing aerator uses a triangular bracket to float on the water body, and a driving member is installed on the top of the triangular bracket to drive the water-lifting impeller extending into the water body. The water-lifting impeller of this structure directly extends into the water body to lift water. Due to the lack of a water-lifting diversion channel, floating objects on the surface of the water body will be adsorbed by the water-lifting impeller during the water-lifting process, which may damage the impeller during operation, thereby causing damage to the impeller. Secondly, the triangular bracket of the existing aerator is an open structure, and the three legs of the triangular bracket are floatingly supported on the surface of the water body. This structure has poor stability. Summary of the invention
