Description

Automatic segmentation type gas fire extinguishing system for extra-large space of prefabricated cabin Technical Field The invention relates to the technical field of steel structure building fireproof, in particular to an automatic segmentation type gas fire extinguishing system for a prefabricated cabin with an oversized space. Background The prefabricated cabin of the camera is a steel structure building, is produced in a factory in a modularized mode, is assembled on site when in use, and has the function of protecting the camera (equipment). The cabin of current prefabricated cabin is whole open space, high temperature flue gas easily spreads in the cabin in a quick unordered way when the conflagration takes place, not only can accelerate the fire to spread to non-ignition region, still can lead to the fire extinguishing agent to spout the back and dilute fast in super large space, spout the homogeneity and drop by a wide margin, be difficult to form effective fire concentration in the fire source region, fire extinguishing efficiency is showing and is reducing, simultaneously, the quick diffusion of flue gas can damage more accurate electrical equipment in the cabin, enlarge loss of property, and the resistance of the poisonous flue gas of high temperature spreads, also increased degree of difficulty and security risk for follow-up personnel rescue and equipment rush repair, can't satisfy the conflagration prevention and control and the demand of putting out a fire in prefabricated cabin extra large space. In order to solve the technical problems, an automatic segmentation type gas fire-extinguishing system with an oversized space of a prefabricated cabin is designed. Disclosure of Invention This section is intended to outline some aspects of embodiments of the application and to briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section as well as in the description of the application and in the title of the application, which may not be used to limit the scope of the application. The invention aims to provide an automatic segmentation type gas fire-extinguishing system for a prefabricated cabin with an oversized space, which has the advantages of capability of rapidly segmenting a protection area, blocking the spread of smoke and improving the utilization rate and the fire-extinguishing efficiency of a fire extinguishing agent, and solves the problems that the smoke is rapidly spread and the fire is easily spread when a traditional prefabricated cabin is provided with a smoke-blocking separation structure, the fire extinguishing agent is easily diluted, the fire-extinguishing efficiency is low, more equipment is easily damaged, and the rescue difficulty is increased.
