Combined embedment type safety refuge device applicable to public places

Abstract

The invention relates to a combined embedment type safety refuge device applicable to public places. The device comprises a main body, closed doors, a storage battery, an oxygen supply self-control device, a cabin pressure regulating and controlling device, an in-cabin gas parameter detection system, an air purification system, a phase-changed refrigeration system and a control console, wherein the main body is in a honeycomb structure consisting of seven cabins and has the advantages of high structural strength and compact connection, meanwhile, underground space is effectively utilized, and the utilization rate of over-ground space is increased; when disaster happens, multiple safety emergency refuge devices are fixedly connected, so that search-and-rescue time of rescue personnel is saved; even though a single unit is split to a separate position in the disaster environment, life safety of escape people in the cabin can be guaranteed; tight locking of the explosion-proof closed doors is realized through simultaneous operation of a large number of extension bars, self-locking is completed through profile connection in self-locking devices, and reliable connection during explosion impact or falling impact is guaranteed accordingly.

Description

technical field [0001] The present invention relates to a safety and emergency refuge device, in particular to a combinable and insertable safety refuge device suitable for public places. Background technique [0002] Urban public places such as workshops, docks, and shopping malls are a complex large system with relatively dense personnel. Once sudden disasters such as fires and earthquakes occur, it will involve a wide range of areas and cause great damage. In response to natural disasters such as earthquakes, some cities in Japan have set up fixed refuge sites with certain safety facilities. Some scholars in the United States have conducted research on refuge sites in large commercial centers in cities. Domestic research on safe emergency refuge devices has just started, and there are no mature technologies and cases. However, there are many shortcomings in the safety and emergency refuge devices studied at home and abroad, such as: unreasonable structure, poor adaptabil...
