Passive escape capsule

Abstract

The invention discloses a passive escape capsule. Multiple cabin segments are connected to form a closed cabin; an air purifying and temperature regulation system, an oxygen supplying system, an environment monitoring system and survival facilities are arranged in the closed cabin; the front and rear ends of the closed cabin are provided with a cabin door respectively; an escape door is arranged on the side of the closed cabin; the cabin segment consists of an outer skin, a thermal insulation layer and an inner skin from outside to inside; the outer skins on the two sides and upper side of the cabin segment are slabs with a corrugated structure, wherein the corrugated structures have an isosceles-trapezoid cross section and are longitudinally arranged in parallel; and the cabin segments are connected in the following way: the two sides and upper side of the cabin segments are connected through an outer flange, and the bottoms of the cabin segments are connected through an inner flange structure. The escape capsule adopts passive design as well as multi-cabin segment connection design, and the wall of each cabin segment is of a multi-layer structure so as to ensure the tightness and strength; and thus, the escape capsule can be conveniently disassembled and carried, and is convenient to use in a narrow mine.

Description

technical field [0001] The invention belongs to the technical field of mine rescue, and relates to a rescue cabin, in particular to a passive rescue cabin. Background technique [0002] The rescue cabin is a safe-haven facility that provides emergency escape space and living conditions for miners in distress when a catastrophic accident occurs underground, and can be moved by traction, hoisting, etc., and meets the requirements of underground mining operations. The rescue cabin is generally airtight The cabin structure has a certain volume. According to specific needs, it has good firmness, water resistance, heat preservation, pressure resistance, etc., and is usually made of strong materials such as steel and alloy. [0003] The rescue cabin in the prior art has the following disadvantages: [0004] 1. The protective device for the pressure relief port of the rescue chamber in the prior art has low strength and general anti-knock performance. The corners of the protective ...

AI Technical Summary

Problems solved by technology

[0004] 1. The protective device for the pressure relief port of the rescue chamber in the prior art has low strength and general anti-knock performance. The corners of the protective box are at right angles. In addition, the vents of the existing protective box are opened on both sides of the protective box. In the event of an accident, the collapsed objects will easily block the vents, so that the pressure relief port cannot complete the pressure relief work, which will affect the personal safety of the personnel in the rescue cabin.

[0005] 2. The air curtain device of the rescue cabin in the prior art is roughly divided into two types, one is small in height and low in noise, and the disadvantage is that the wind pressure is small and the air volume is small. Such an air curtain is often used as a commercial facility, but because of its wind pressure It is small and cannot meet the needs of industrial use; another centrifugal air curtain equipment has a large height, large air volume and pressure, and high noise, which can meet the needs of industrial use, but because of its large volume, the requirements for the use environment are also The air curtain used in the mining rescue cabin must have sufficient wind pressure, and the space in the cabin should be saved as much as possible.

Most of the existing compressed air spray devices or air curtain devices are of integral structure, and air outlet holes are directly arranged on the air curtain housing or spray housing. After a long period of use, the air outlet holes are prone to blockage, because the air outlet holes The shell is a one-piece structure, which is very inconvenient for inspection and maintenance

[0006] 3. When a mine disaster occurs, it is often accompanied by strong vibration and pressure, strong explosion and impact, which puts forward very high requirements on the performance and service life of the rescue cabin shell. The usual rescue cabins are often not perfect, and there are pressure and earthquake resistance. However, it cannot resist the defects of explosion impact, or does not have the ability of heat insulation and high temperature resistance, and is not enough to deal with the damage caused by explosions, earthquakes and other disasters.
