1results about How to "Avoid flying out" patented technology

This utility model relates to the field of fish farming escape prevention technology, specifically to a fish farming escape prevention device, including a base, a fishing net tube fixedly installed on the top of the base, a barrier tube slidably connected inside the fishing net tube, a sealing plate installed on the top of the barrier tube by screws, and an airbag fixedly connected to the outside of the sealing plate. The airbag changes with the water level. The fishing net tube is equipped with stirring blades to agitate the water flow. The use of the airbag allows the height of the escape prevention device to change with the water level, eliminating the need for manual adjustment and preventing fish from easily flying out or swimming out of the top of the escape prevention device, thus ensuring the effectiveness of the escape prevention device. Furthermore, the external wind force drives the blades to rotate, which agitates the water flow inside the fishing net tube, allowing dissolved oxygen and nutrients in the water to be evenly distributed, avoiding local hypoxia or nutrient overload, and providing a good growth environment for the fish.
