The utility model belongs to transformer processing technical field especially relates to a gallows used in transformer processing, including the chassis and the gallows of fixed connection in the left and right sides of chassis, the top of chassis is provided with clamping device, the clamping device includes sliding mechanism and buffer mechanism, the front of top of chassis is connected with baffle, sliding mechanism includes clamping plate, slide rod, sliding sleeve, locking bolt and bolt hole. This gallows used in transformer processing, when processing the transformer, first place the transformer on the top of clamping plate, push clamping plate and drive sliding sleeve to slide on the surface of slide rod, when the transformer contacts baffle, continue to push clamping plate and make the transformer extrude air bag, then use locking bolt to pass through through -hole and be connected in the inside of bolt hole with screw thread, fix the transformer, according to the size of transformer can replace the locking bolt of different length, be convenient for the adaptation of different transformer.

This invention discloses a fuel atomization system suitable for the combustion chamber of a regenerative micro gas turbine, comprising: a T-shaped evaporator, a swirling oil-gas duct, a coaxial atomizing nozzle, an air intake pipe, and a fuel line protection sleeve; the T-shaped evaporator, the swirling oil-gas duct, and the coaxial atomizing nozzle are arranged coaxially, the air intake pipe is eccentrically connected to the side wall of the coaxial atomizing nozzle and can introduce high-pressure gas from the section before the regenerator after the compressor, the initially atomized mixed oil and gas enters the swirling oil-gas duct for further atomization and then evaporates and is ejected through the T-shaped evaporator, the fuel line protection sleeve is coaxially arranged on the outside of the swirling oil-gas duct and the coaxial atomizing nozzle and can avoid the direct impact of high-temperature backflow gas on the coaxial atomizing nozzle. This invention can significantly optimize fuel atomization quality, shorten the combustion chamber length, improve combustion efficiency, and improve the uniformity of combustion chamber outlet temperature distribution by adding a coaxial atomizing nozzle and an air intake pipe upstream of the traditional evaporator.

This utility model belongs to the field of fire extinguishing in cable channels, specifically an automatic fire extinguishing device for cable channels in thermal power plants. It includes a cable channel section, with a pair of pre-pressurized liquid storage tanks fixedly connected to the top of the cable channel section; a pair of transmission pipes fixedly connected to the inner wall of the cable channel section; the transmission pipes and the pre-pressurized liquid storage tanks are in communication; a hinge is rotatably connected to the side wall of the transmission pipe; a fusible link is slidably fitted in the middle of the transmission pipe; a fixing screw is threaded to the end of the hinge; the fixing screw and the surface of the transmission pipe are threadedly connected; a connecting component is provided at the bottom of the hinge; by using the fusible link, its low melting point characteristic allows it to break automatically when the temperature exceeds a critical point, thereby unlocking the transmission pipe. Finally, the pressure inside the pre-pressurized liquid storage tanks rapidly releases the extinguishing agent, accelerating the treatment of the fire source and reducing the fire extinguishing activation time. The extinguishing agent is rapidly sprayed out using the pressure inside the pre-pressurized liquid storage tanks.

The application discloses a preparation method of a monopropellant monolithic catalyst, selects a honeycomb ceramic carrier which has good heat conductivity and heat shock resistance and can keep stable structure in a high-temperature environment, coats a modified alumina coating on the surface of the ceramic carrier, and then loads noble metal as a catalytic active component through an impregnation method, so that the connectivity between the noble metal active component and the carrier is enhanced, the noble metal loading capacity is increased, the coating firmness is improved, the catalyst breakage rate is significantly reduced, and the catalyst thermal stability is improved. The monolithic catalyst prepared by the application has high catalytic activity, good coating firmness, and the modified alumina coating can also increase the strength of the carrier, can effectively inhibit sintering and phase change of the carrier in a high-temperature environment, improve the thermal stability, and is not easy to break in a high-temperature environment.

The utility model discloses a kind of automatic isolation fireproof doors of coal mine well and alley, it includes two parallelly arranged isolation door frames, the middle part of isolation door frame is uniformly fixed with vertical plate, one side of vertical plate is rotatably connected with pedestrian transport isolation door, the side of vertical plate, away from pedestrian transport isolation door, is fixedly connected with horizontal plate, horizontal plate is rotatably connected with the isolation door above floating groove;Vertical plate is rotatably connected with the isolation door on the upper portion of belt conveyor;Isolation door frame bottom is fixed with door sill, door sill is rotatably connected with bottom isolation door;Rotatably connected with middle isolation door between vertical plate and isolation door frame.When fire occurs, through first pneumatic jack and second pneumatic jack, the closing action of pedestrian transport isolation door, the isolation door on the upper portion of belt conveyor, the isolation door above floating groove, middle isolation door and bottom isolation door is completed, completely plugging is realized at the connecting section of belt conveyor through fire door, the sealing between fire door and belt conveyor is improved, the risk of flame and toxic gas leakage spread is reduced, which is beneficial to the personal safety and coal mine safety of underground operating personnel.
