Fixed shelter with double-protection structure

Abstract

The invention discloses a fixed shelter with a double-protection structure, which is mainly applied in facilitates underground, such as a down hole in a mine, the interior of a tunnel, a subway, and the like, and civil defense facilitates, and is used for emergent avoidance of staffs in danger. The shelter comprises a roadway lifesaving guide area 1, a double-protection area 2 and a safety sheltering area 3, wherein the roadway lifesaving guide area 1 comprises a lifesaving guide device 4 arranged in a roadway, a shelter door-closing and alarming device and a sensor 5 of an environmental security detection device; the double-protection area 2 is provided with double protective walls which are provided with protective doors; the protective door arranged on a first protective wall 10 is a waterproof door 13, the protective door arranged on a second protective wall 11 is a fireproofing explosion door 14, and the waterproof door 13 and the fireproofing explosion door 14 are arranged in a staggered manner; the double-protection area 2 is internally provided with a self-helping device 15, an air purifying device 9 and a sensor 8 of the environmental security detection device; and the safety sheltering area 3 is internally provided with an oxygen system, food, water, a power supply, an air purifying device 32, the environmental security detection device 32 and medical facilities which are required for self-helping of the staff in danger, as well as communication facilitates communicated with the outside. The shelter has good sealing, waterproof, fireproof, anti-explosion, heat insulating, pressure impacting resistant performances, and is convenient to use.

Description

technical field [0001] The invention relates to a life-saving facility, which is specifically applied to underground facilities such as underground mines, inside tunnels, subways, and civil defense facilities, and is used for emergency avoidance by persons in distress. Background technique [0002] When disasters such as flooding, fire, explosion, and toxic and harmful gases occur in underground facilities such as mines, tunnels, and subways, it is very difficult for people to escape due to the suddenness, complexity, and strong destructive power of the disaster. It is easy to cause a large number of casualties in a short period of time. One of the effective coping methods is to set up some fixed shelters in underground facilities and civil defense projects for people in distress to enter to avoid disasters, so as to reduce the degree of casualties. [0003] So far, fixed shelters have been basically equipped with compressed air supply, water supply, and communication syste...

Problems solved by technology

Considering the great destructive power and complex causes of accidents in underground facilities, unilateral considerations such as sealing and fire prevention cannot meet the needs of current fixed shelters
