A windable display module and a display device. The display module includes a plurality of film layers stacked together and at least one connecting layer group arranged between the plurality of film layers. In a stacking direction, the at least one connecting layer group is in contact with its adjacent film layer, so that a variable connecting force is generated between the film layers that are adjacent to the at least one connecting layer group. During a winding process or an unwinding process of the display module, a first connecting force is generated between the film layers that are adjacent to the at least one connecting layer group. During a displaying process of the display module, a second connecting force is generated between at least parts of the film layers that are in a displaying region. The first connecting force is less than the second connecting force.

Windable display module, and display device

A mobile liquid nitrogen fire extinguishing system for a utility tunnel is provided, including a liquid nitrogen production assembly, a fire extinguishing assembly, a monitoring device, and a liquid nitrogen conveying tubing. The mobile fire extinguishing assembly includes a liquid nitrogen storage tank and a liquid nitrogen booster pump. The liquid nitrogen storage tank is connected to the liquid nitrogen booster pump. The liquid nitrogen booster pump conveys liquid nitrogen to branch pipes in the utility tunnel through the liquid nitrogen conveying tubing. Liquid nitrogen injection ports are formed in each of the branch pipes. The liquid nitrogen production assembly is mobile and conveys the prepared liquid nitrogen to the liquid nitrogen storage tank. The monitoring device includes a first monitoring assembly and a second monitoring assembly.
