The utility model discloses an intelligent management system for a centrifuge RFID rotor. The intelligent management system comprises a rotor, a motor assembly and a connecting seat, an RFID chip card is arranged on the rotor, and an RFID antenna matched with the RFID chip card is arranged on the connecting seat; the output end of the motor assembly is connected with the rotor; the RFID antenna is connected with an external card reader through a circuit; according to the scheme, the RFID chip card and the rotor are arranged together, rotor information such as rotor factory information, rotor operation parameters and rotor operation time records can be recorded through the RFID chip card, non-contact rotor identity recognition can be achieved through the RFID antenna, safe operation of the rotor is achieved, and meanwhile, the RFID chip card can be used for identifying the rotor through the reader-writer. The electronic tag is quickly read and written, and rotor operation parameters and operation life management is realized through data interaction, so that the rotor of the centrifugal machine can be safer and more efficient in use.

The utility model discloses a main line knotless connection splayed ring, comprising a hollow cap, the top end of which is provided with a through hole in a penetrating manner; a sub-line connecting ring is rotatably arranged at the bottom end of the structural column; the connecting column is used for connecting the hollow cap and the structural column into an integrated structure; the bottom face of the hollow cap is provided with an annular blocking face, the inner diameter of the annular blocking face is larger than that of the penetrating hole, so that a knot of the main line which penetrates through the penetrating hole and is knotted is limited by the annular blocking face in a pull-back state, and therefore a knot-free self-locking connecting structure of the main line is formed. The bottom end of the structural column is provided with a cavity, and the sub-line connecting ring is rotatably arranged in the cavity, so that the sub-line can freely rotate by 360 degrees relative to the structural column in use. The structure can improve the connection strength, simplify the operation and improve the anti-winding performance, and is suitable for various fishing environments.

The application belongs to the technical field of biological pesticides, and particularly relates to application of a bacteriostatic agent in inhibition of Fusarium fungi. The bacteriostatic agent contains at least one component of chromanol or tryptanthrin, and can effectively inhibit the growth of F. proliferatum, and the inhibition rate of F. proliferatum is as high as 100%. Since F. proliferatum is a dominant pathogenic fungus causing rhizome rot of Lanzhou lily, the bacteriostatic agent provided by the application can also be used for prevention and treatment of rhizome rot of lily, and the effective active component in the bacteriostatic agent is a metabolic product of microorganisms, so that the bacteriostatic agent has the advantages of green environmental protection, high efficiency and safety.

The utility model belongs to the technical field of harmonious locomotive brake assembly, and particularly discloses a harmonious locomotive snap ring assembly supporting device which comprises a handle, a connecting rod, a semicircular groove frame and a second snap ring, the right end face of the handle is connected with the left end face of the connecting rod, and the transverse semicircular groove frame is arranged on the upper end face of the right end of the connecting rod; the second clamping ring is clamped in the clamping groove of the semicircular groove frame; the device is simple in design structure, low in manufacturing cost, convenient to use, efficient and safe, and the assembly efficiency of the brake is greatly improved.
