[0003] Under high-density aquaculture, metabolic products and leftover bait of aquaculture organisms accumulate in large quantities, consuming dissolved oxygen in the water. In addition, the poor fluidity of aquaculture water makes it difficult to replenish oxygen, which can easily cause water hypoxia, trigger stress responses in aquatic animals, and even lead to large-scale deaths, causing huge economic losses to farmers. At the same time, the hypoxic environment will also promote the growth of harmful microorganisms, further deteriorating the aquaculture environment.

[0004] In the field of water flow control, many natural water bodies or artificial waters have insufficient water flow due to factors such as topography, water flow conditions, etc. The slow flow of water makes it difficult for pollutants to diffuse and dilute, and the dissolved oxygen cannot be effectively replenished, resulting in the degradation of the ecological function of the water body. Whether it is an urban landscape water body or a water source for irrigation or industrial water, it is urgent to improve the flow of water bodies and increase the dissolved oxygen content to ensure the ecological health and use function of the water body.

[0005] Traditional water-pushing devices often have problems such as high energy consumption, low efficiency, poor environmental adaptability and low reliability. With the enhancement of environmental awareness and technological progress, the market demand for efficient, environmentally friendly, reliable and flexible water flow control devices is growing.
