Of course, in another embodiment, the liquid nitrogen tank 13 may be fixed to the pry body and transported together with the pry body. The existing fire extinguishing device is easy to gasify because of long-distance liquid nitrogen conveying, and the actual fire extinguishing point reached by the liquid nitrogen is mainly gaseous nitrogen, so that the cooling and suffocation effects are poor. And aiming at scattered buildings such as urban complexes, underground garages and the like, if a liquid nitrogen conveying pipeline is laid in advance, high construction cost and later maintenance cost are increased. Through with each subassembly integration on the sled body, only need transport the sled body through transport means such as freight train, another end mouth of pipe of reuse play liquid nest of tubes 1 connects liquid nitrogen container 13, can spray liquid nitrogen and accomplish to put out a fire. The installation of the fire extinguishing device can be completed only by connecting the liquid outlet pipe group 1 with the interface of the liquid nitrogen tank 13, the field installation workload is reduced, the construction cost of the device is saved, the device is convenient to move and transport, and the problem that the liquid nitrogen is conveyed for a long distance and is extremely easy to gasify does not exist.
Wherein, go out the liquid nest of tubes 1 and include gaseous phase pipe 2 and liquid phase pipe 3, all be provided with on gaseous phase pipe 2 and liquid phase pipe 3 and open and close valve 14 and temperature sensor 4, the one end mouth of pipe of gaseous phase pipe 2 is connected with the inlet of tubing pump 7, the one end mouth of pipe of liquid phase pipe 3 is connected with the inlet of tubing pump 7, gaseous phase pipe 2 and liquid phase pipe 3 communicate each other through tubing pump 7.
