4results 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.

The present application provides a production device for metallic silicon, including a shell, a conveyor platform and two first motors are installed on the side wall of the shell, the output ends of the two first motors are fixedly connected to crushing rods, and both sides of the shell are provided with protective adjustment mechanisms, the protective adjustment mechanism includes a second motor and a fan blade assembly, the second motor is located above the shell, the fan blade assembly is installed on the output end of the second motor, and the protective adjustment mechanism also includes a fixed rod, the fixed rod is fixedly connected to the side wall of the shell, and the end face of the fixed rod is provided with a vertical rod. The present application sets a second motor, a screw, a blade, and a first spring, and with the help of the drive of the second motor, the blade can be driven to rotate, and then a windshield is formed on both sides of the shell, so as to achieve the effect of concentratedly discharging the dust generated after the crushing rods crush the ore, and can also resist part of the gravel to avoid the situation where the gravel flies out as much as possible.

The utility model discloses a cleaning device for electroplated parts. The cleaning device comprises a cleaning pool, an air cylinder is arranged on one side of the cleaning pool, and a motor is arranged on one side of the air cylinder; a sliding plate is arranged on one side of the cleaning pool, a rotating cylinder is arranged on one side of the sliding plate, and a positioning rod is arranged on one side of the rotating cylinder; wherein a sliding cylinder is arranged in the middle of the rotating cylinder, a collecting tank is arranged on one side of the sliding cylinder, a sliding rod is arranged on the other side of the sliding cylinder, and by arranging a pressing rod and fixing the electroplated part in the middle of the positioning frame, the electroplated part is conveniently fixed in the middle of the positioning frame, and meanwhile damage to the surface of the electroplated part is avoided; and unfolding and contracting of a pressing rod are automatically controlled through ascending and descending of a rotating cylinder, so that the device is more convenient and faster to use, and by arranging a collecting tank, the electroplated part is conveniently taken out, and the cleaning efficiency of the electroplated part is conveniently improved.
