This utility model discloses a damping-actively adjustable vibration damper, belonging to the technical field of vibration damper technology. The damping-actively adjustable vibration damper includes an oil tank, inside which is a working cylinder. An oil storage chamber is separated from the oil tank by the working cylinder. A piston rod is installed inside the working cylinder, and a reset valve assembly is bolted to the bottom end of the piston rod. A bottom cover is welded to the bottom of the oil tank, and a compression valve assembly is installed on the upper part of the bottom cover. The compression valve assembly and the working cylinder form a working chamber, which is filled with magnetorheological fluid. When the excitation coil malfunctions, only the coil protective cover needs to be opened to remove the excitation coil for repair or replacement, without disassembling the internal structure of the vibration damper. This greatly reduces the difficulty of maintenance and upkeep of the magnetorheological vibration damper, making it convenient to use.

The utility model relates to stainless steel valve box technical field discloses a stainless steel valve box, including valve box mechanism, valve box mechanism includes stainless steel box, first air inlet groove and second air inlet groove, first air inlet groove is set in the front of stainless steel box top end, second air inlet groove is set in the back of stainless steel box top end, the top of stainless steel box is equipped with dehumidification structure, the front of valve box mechanism is provided with the door body, the utility model adopts double mode ventilation and radiates heat, under the daily working condition, air forms natural convection through air inlet, first flow guide chamber, first air inlet groove, realizes basic heat dissipation, when temperature sensor monitors and stainless steel box internal temperature exceeds the threshold value of setting, drives the automatic start of air suction fan, will introduce air into second flow guide chamber, after the drying of the air drying agent placed on the openwork net, through second air inlet groove is sent into the inside of stainless steel box, avoids the humid air and accelerates the aging of seal.

This invention discloses a deep-sea microbial antimicrobial peptide mining method driven by deep-sea learning and its application in rice wine, belonging to the field of deep-sea extreme environment microbial resource development and traditional brewing food preservation technology. This invention efficiently mines novel, highly active antimicrobial peptides from deep-sea cold seep extreme habitat microbial metagenomic data by constructing a multimodal deep-sea learning model. These peptides exhibit significant inhibitory activity against Gram-negative bacteria, Gram-positive bacteria, and fungi. Furthermore, in the rice wine system, the addition of 7.5 μM of this antimicrobial peptide significantly inhibited the proliferation of *Lactobacillus fructose*, with an inhibitory effect comparable to that of the Gram-positive antimicrobial peptide Magaiin II. These deep-sea microbial antimicrobial peptides are natural, safe, highly efficient, biodegradable, and do not affect the flavor of rice wine, promoting the high-value utilization of deep-sea microbial resources and the high-quality development of the rice wine industry, possessing significant industrial value and broad application prospects.

The utility model discloses a polyurethane wear-resistant rubber ring for luxury stone cutting equipment. The polyurethane wear-resistant rubber ring comprises a rubber ring body, one side of the inner side of the rubber ring body is fixedly connected with a binding surface, and the middle of the inner side of the rubber ring body is fixedly connected with a connecting section; wherein a clamping block is fixedly connected to one side of the connecting section, an empty groove is formed in one side of the clamping block, a connecting belt is arranged on one side of the empty groove, and the annular guide wheel rubber ring is arranged, so that the influence of tensile resilience stress on the service life of the rubber ring when the rubber ring is used is conveniently reduced, the service life of the rubber ring is longer, and the service life of the rubber ring is prolonged. And by arranging a connecting section, a clamping block, an empty groove and a connecting belt on the inner side of the wear-resistant rubber ring, the rubber ring and the guide wheel are more convenient to mount, rapid shrinkage of the clamping block is also convenient to realize after the clamping block and the guide wheel are connected through the connecting belt, and the connection stability between the clamping blocks is enhanced.

The utility model discloses a flame-retardant fireproof power cable, relates to the technical field of cable manufacturing, and solves the problems of insufficient structural strength, poor wear resistance and substandard flame-retardant fireproof performance of a power cable in the prior art. Comprising a wire core assembly and an outer sheath wrapping the outer wall of the wire core assembly. The cable further comprises a protection reinforcing assembly, the protection reinforcing assembly comprises an inner sheath, a reinforcing layer, a metal sheath and a fireproof layer which are arranged in the outer sheath, the inner sheath wraps the cable core assembly, and the reinforcing layer is arranged between the outer side of the inner sheath and the inner side of the metal sheath; according to the utility model, the protection reinforcing assembly is integrally designed in the outer sheath, and the protection reinforcing assembly comprises the inner sheath, the reinforcing layer, the metal sheath and the fireproof layer, so that the strength, the anti-pressure capability and the anti-bending capability of the cable are improved to a certain extent under the action of the reinforcing layer and the metal sheath, thereby prolonging the service life of the cable.
