Middle and primary school schoolyard firefighting lifesaving air cushion

Abstract

The invention discloses a middle and primary school schoolyard firefighting lifesaving air cushion. The middle and primary school schoolyard firefighting lifesaving air cushion is characterized in that the lifesaving air cushion comprises three parts including a base, compression springs and an air cushion body; and the lower end of the air cushion body is supported on the base through the multiple compression springs. The middle and primary school schoolyard firefighting lifesaving air cushion is suitable for teaching building architecture fire safety, teachers and students can achieve continuous usage at the same time when escaping is emergent and difficult, and life guards can stably and safely land. The advantages that the structure is novel and unique, usage and storage are convenient, rescuing is safe and the speed is high are achieved. Different from existing air cushions, the lifesaving air cushion is internally provided with the compression springs so that the air cushion bodycan have the elastic buffering function that the effect is better and the function is more powerful, and accordingly, the comfort and safety of the whole air cushion are enhanced.

Description

technical field [0001] The invention relates to the field of building fire safety, in particular to a fire-fighting air cushion for primary and secondary schools. Background technique [0002] With the development of the world economy, there are many tall buildings in various cities. And accidents such as high-rise fires, explosions, and earthquakes occur from time to time, and high-rise escape and self-rescue have become an urgent problem to be solved. In general multi-functional high-rise buildings, the internal passages are intricate. Once a fire breaks out, the vents in the building will quickly expand the fire and smoke, and will soon spread to every corner. Once covered by thick smoke, it will be difficult to move. Then he was trapped upstairs and couldn't get out. In order to solve this difficult problem, life-saving air cushions arise at the historic moment exactly in such an environment. [0003] After searching, it is found that the invention of patent No. CN201...

Problems solved by technology

[0004] However, when a sudden disaster strikes, usually the elevator cannot be used due to a power outage, and the stairs are blocked by the crowd. The general ground rescue equipment may not be enough in height, and it will not be able to quickly and quickly because of the bulkiness of the equipment. The implementation of rescue, thus delaying the rescue time

Therefore, the application of life-saving air cushion just seems very important; Yet although existing life-saving air cushion is simple in structure, existing life-saving air cushion is only the cushion of inflating, utilizes the active force of gas to produce buffer to escape personnel after inflating, thereby reaches the purpose of rescue. Purpose; but the existing life-saving air cushion can only rely on the force of the gas inflated into the air cushion to cushion the escapees, so the cushioning effect is relatively poor; To realize the convenient and fast escape of a large number of people, the scope of use of the existing simple life-saving air cushion will be limited; in addition, the surface of the existing air cushion is too smooth, and the escape personnel will fall to the outside of the air cushion when they fall
