  • Patent number: 12157981
    Abstract: The invention provides a method for preventing super large-scale floods and debris flows. First, the scale corresponding to certain standard floods in the watershed is evaluated based on field investigations and historical data. Second, the design standards of the system are chosen based on the prevention of super large-scale floods, and the design standard of critical control engineering is further determined. Finally, the design methods of check dams with different functional zones are proposed according to the design standards of critical control engineering. The invention allows part of the key control dam to fail under safe operating conditions of the entire system by increasing the cross-sectional areas and the flow discharges. The unbroken foundation of the dam can effectively control the channel entrainment and regulate the cross-sectional discharge. The design is helpful in mitigating giant floods and debris flows, thus protecting downstream infrastructures.

    Abstract: The present disclosure relates to a solid-state circuit breaker and a control method therefor. The solid-state circuit breaker comprises a solid-state switch, a first measurement unit, a second measurement unit, a control unit, and a driving unit. The first measurement unit is used to measure the current and/or voltage at a first terminal of the solid-state switch. The second measurement unit is used to measure the current and/or voltage at a second terminal of the solid-state switch. The control unit is used to: when the solid-state switch is turned off, determine whether the first terminal is charged; determine whether the second terminal is charged; control the driving unit to input a pulse voltage to a control terminal of the solid-state switch; and after the pulse duration has ended, determine the type of load.

  • Patent number: 12024842
    Abstract: The method for preventing and controlling glacial lake outbreak flood and related debris flows by the present invention is mainly controlling the scale of the floods by separating water and rocks and dispersing its energy step by step. The cascading amplification effects of floods can be reduced by controlling the initiation of source material with energy dissipation by using ground sills, groups of piles, and placed large stones and prefabricated artificial structures. The diversion dam built in the downstream area discharge floods in different layers, which can quickly guide water to the main river. The preconstructed engineering system can be used in a timely manner to prevent and control floods and debris flows induced by a sudden outburst of glacial lakes in areas with important facilities and inhabitants enduring the risk of natural hazards. Prevention and control systems can separate floods and debris flows and dissipate their energy.

  • Patent number: 11952596
    Abstract: Application of glutamate dehydrogenase GdhA of Peptostreptococcus asaccharolyticus in increasing the yield of poly-?-glutamic acid from Bacillus licheniformis. The glutamate dehydrogenase GdhA of the Bacillus licheniformis WX-02 per se is replaced with the glutamate dehydrogenase derived from the Peptostreptococcus asaccharolyticus by means of homologous recombination, which significantly increases the level of synthesizing the poly-?-glutamic acid for the Bacillus licheniformis, and the yield of the obtained poly-?-glutamic acid from strains is increased at least by more than 20% compared with control strains.

  • Patent number: 11874193
    Abstract: Provided is an ice avalanche-type glacial lake outburst surge generation and height measurement device. A glacial lake outburst test device includes a glacial lake simulation module and an ice avalanche surge module. An impact path, an impact angle, an impact scale, an impact velocity and a landslide density of an ice avalanche slider are controlled by simulation means. During formation of ice avalanche surges, the ice avalanche slider rushes into the glacial lake at a high speed, an ice avalanche pushes water to move in a sliding direction, thus forming a first surge, then continues to move to the bottom of the lake under the inertia and discharges a certain amount of water at its back. Movement of the landslide drives surrounding water to converge quickly into the back area, thus forming a second surge. Surge waves evolve around with a water entry point as a center.
