2results 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.

The utility model relates to the technical field of resonators, and provides a high-stability quartz crystal resonator, which is used for packaging a quartz crystal and an electrode, and comprises a vertical side wall of a base provided with an inclined groove; the cover shell is arranged on the base in a covering mode, the side wall, matched with the side wall, provided with the groove, of the cover shell is provided with an inward-concave structure, the inward-concave structure is clamped in the groove, the outer side of the inward-concave structure is provided with an inclined inserting groove, and the inserting groove is internally used for containing tweezers petals of tweezers. By means of the technical scheme, the problem that in the prior art, a packaging shell is inconvenient to stably clamp through tweezers is solved.
