High-pressure respirator fully-wrapped composite gas cylinder with carbon fiber reinforced aluminum inner container for fire fighting

Abstract

The invention discloses a high-pressure respirator fully-wrapped composite gas cylinder with a carbon fiber reinforced aluminum inner container for fire fighting. The high-pressure respirator fully-wrapped composite gas cylinder comprises the aluminum inner container, wherein the aluminum inner container comprises an aluminum inner container bottle bottom, an aluminum inner container barrel body, an aluminum inner container bottle shoulder and an aluminum inner container bottleneck; a carbon fiber fully-wrapped layer on the aluminum inner container barrel body is formed by alternatively winding a longitudinal carbon fiber wrapping layer and an annular carbon fiber wrapping layer according to a stacking sequence; an anti-impact glass fiber protective layer is further wrapped on the surface of the carbon fiber fully-wrapped layer; and a layer of polyurethane lacquer is coated on the outer surface of the aluminum inner container as an electrocorrosion resistant coating. The high-pressure respirator fully-wrapped composite gas cylinder meets reasonable stress field distribution and is ensured to be capable of bearing maximal bursting pressure in case of using least fibers, so that the bursting position starts from the aluminum inner container barrel body of the composite gas cylinder, and therefore, the composite gas cylinder is guaranteed to have lasting and good airtight performances, and optimal safety performances.

Description

technical field [0001] The invention relates to a respirator composite material high-pressure gas cylinder used for fire-fighting to be filled with designated air, in particular to a high-pressure fire-fighting respirator carbon fiber-reinforced aluminum liner full-winding composite gas cylinder. Background technique [0002] With the rapid development of my country's economic construction, the process of urbanization and industrialization continues to accelerate, a large number of crowded places, high-rise and underground buildings, and industrial buildings continue to emerge. Hidden dangers and risks are increasing day by day. In recent years, my country's major fire accidents have generally shown an upward trend, the situation continues to be severe, and fire fighting and rescue tasks have become more and more complicated, and cases of firefighter casualties in my country have also occurred frequently. In the accident cases of firefighters' casualties, some of them were c...

Problems solved by technology

[0004] In order to prolong the respiratory protection time of firefighters, many air respirator manufacturers have developed large-volume air respirators such as 9L, 12L, and 6.8L double-bottle respirators. However, when the volume of the air respirator becomes larger, the equipment weight of the respirator, The shape and volume will also increase accordingly, which will bring additional physiological burden to firefighters, increase their gas consumption rate, and have an adverse effect on extending the use time

In addition, some people propose to use oxygen respirators to prolong the respiratory protection time in the fire scene. However, due to the disadvantages of relatively poor comfort and relatively cumbersome maintenance, oxygen respirators are not widely used in fire brigades at home and abroad. Respirators remain the most frequently used respiratory protective equipment for firefighters
