This invention discloses a redox-active metal-organic framework material, its preparation method, and its applications. The metal-organic framework material is prepared by a solvothermal method using bis(triphenylaminetetracarboxylic acid) and inorganic manganese compounds as raw materials, N,N-dimethylformamide, deionized water, and 1,4-dioxane as solvents, and hydrochloric acid as a catalyst. The metal-organic framework of this invention exhibits good crystallinity and thermal stability, and possesses reversible redox activity. Electrochromic devices prepared using this framework display three different color transitions.

The invention provides a vortex atomization liquid drainage and gas production device and method, and belongs to the technical field of liquid drainage and gas production of natural gas wells. The device is used for being installed in an oil pipe and is provided with an atomization part, the atomization part is provided with a connecting pipe with two open ends and an injection pipe with only one open end, the first open end of the connecting pipe is communicated with a tubular vortex forming part, and the second open end of the connecting pipe is communicated with a first through hole formed in the closed end of the injection pipe. A second through hole is formed in the side wall of the injection pipe, the second through hole communicates with one end of a first channel, the other end of the first channel is used for communicating with a third through hole formed in the oil pipe, and gas-liquid two-phase fluid enters from the end, away from the first opening end of the connecting pipe, of the vortex forming part; and the gas-liquid two-phase fluid is sprayed out from the end part, far away from the second opening end of the connecting pipe, of the spraying pipe. The device can discharge the accumulated liquid in the shaft without the help of external force, and is simple in structure and free of movable parts.

The utility model discloses an automobile engine shell with a damping function, which relates to the technical field of automobile engine shells and comprises a shell main frame, an extension frame is integrally formed at the upper end of the shell main frame, and two limiting top plates are mounted on the inner wall of the extension frame. Threaded penetrating holes are formed in the centers of the interiors of the two limiting top plates correspondingly. The limiting screw rod is movably arranged in the two threaded penetrating holes in a penetrating mode, a damping shock absorber and a rotating handle are welded to the two ends of the limiting screw rod correspondingly, and the size of the damping shock absorber and the size of the rotating handle are both larger than the hole diameter of the threaded penetrating holes; the problems that according to an existing automobile engine shell, an automobile engine in the shell is subjected to buffering and damping treatment through an external damping mechanism, the occupied space of the shell can be increased due to the fact that the shell is provided with the damping mechanism, damage is likely to happen, the automobile engine shell is inconvenient to install, and the service life is affected are solved.
