The invention relates to an instant installation safety fixation hinge-free door which is mainly composed of a door support, a door frame, a protruding bolt and a groove. The door support is arranged on one side of the door frame and mainly serves as a door board support, the door frame is arranged on one side of the door support and mainly serves as a door support fixing frame, the protruding bolt is arranged on one side of the door frame in a protruding mode, the protruding head is large in head and small in inside, the protruding bolt is mainly matched with the groove, the groove is recessed and formed in one side of the door support, the recessed portion is small in opening and large in side, and the groove is mainly used for containing the protruding bolt. The door has the advantages of being simple in structure, exquisite, multipurpose, wide in use, free of hinge installation, convenient and durable to install and use, safe, low in manufacture cost and better in comprehensive effect, saving energy and protecting environment.

The invention discloses a rotary catapult take-off platform for carrier-borne aircraft of an aircraft carrier, and mainly relates to the field of military weapons. It includes a rotating seat support, a rotating column is vertically arranged on the top of the rotating seat supporting, a rotating platform is arranged on the rotating column, and several parking positions are arranged in an annular array on the top of the rotating platform, and one end of the parking position A baffle groove is provided, and a baffle that can be opened and closed is arranged in the baffle groove, and a locking device for locking the wheels of the aircraft is provided on one side of the baffle groove. The beneficial effects of the present invention are: its technical structure is simple, the weight cost and energy consumption are relatively small, the parts are less and the maintenance is less, and multiple aircraft can be ejected simultaneously or continuously, and take off in a gentle and uniformly accelerated rotation mode, which can be ignored without fresh water. Wind direction, smooth instantaneous load, suitable for a wide range of take-off models, strong speed controllability, no runway approach, does not occupy too much deck area, and does not have any electromagnetic interference, and can be elevated or multi-layered.

The invention relates to a circulation flow reactor with a guiding body component. The circulation flow reactor comprises an outer cylinder and a guide cylinder arranged in the inner cavity of the outer cylinder, wherein a water outlet is formed in the upper part of the outer cylinder; a cavitation spray head communicated with a water inlet pipeline is arranged below the guide cylinder or between two walls of the bottom end of the guide cylinder; a guiding body is arranged in the inner cavity of the guide cylinder; the guiding body is positioned above the cavitation spray head and directly faces the spray end of the cavitation spray head. According to the circulation flow reactor, a synergic effect is generated under the effects of ultrasonic vibration and flapping jet, and a great number of free radicals are generated, so that the hydrodynamic cavitation energy consumption of the equipment is reduced, the ultrasonic cavitation strength is greatly improved, the sewage treatment capacity is strengthened, and the hydrodynamic cavitation capacity for degrading organic pollutants is effectively improved; moreover, gas distribution in liquid is dispersed by using the guiding body, the aggregation of gas in the liquid is prevented, and the gas-liquid contact area is further increased. The circulation flow reactor also has the advantages of convenient operation, easy management, low cost, simple technological structure and the like, and is suitable for industrial popularization and application.

The invention relates to a hydraulic acoustic cavitation circulation flow reactor which comprises an outer shell and a guide shell arranged in the inner cavity of the outer shell, wherein the upper part of the outer shell is provided with a water outlet; a cavitation sprayer communicated with a water inlet pipeline is arranged between the two walls of the lower part or bottom end of the guide shell; and the cavitation sprayer is composed of a first fixed plate, a first nozzle, a second nozzle, a vibrating bar, a second fixed plate and a connecting rod. The synergic effect is generated under the actions of ultrasonic vibration and slit jet so as to generate abundant free radicals, so that the hydraulic cavitation energy consumption of equipment is lowered, the ultrasonic cavitation intensity is greatly enhanced, the sewage treatment capacity is enhanced, the capacity of hydraulic cavitation for degrading organic pollutants is effectively enhanced, the gas-liquid mixing can be enhanced, and the mass transfer and heat transfer effects between gas and liquid are enhanced. The hydraulic acoustic cavitation circulation flow reactor is convenient to operate and easy for management, has the advantages of low cost, simple technical structure and the like, and is suitable for industrialized popularization and application.
