Novel lifesaving parachute used under high-rise emergency

Abstract

The invention discloses a novel lifesaving parachute used under high-rise emergency. The novel lifesaving parachute comprises an outer lifesaving parachute bag, an inner lifesaving parachute bag, a lifesaving parachute body, a lifesaving parachute body connecting belt, an adult lifesaving back strap and a child lifesaving back strap. After being packed up, the lifesaving parachute body is put in the inner lifesaving parachute bag. The inner lifesaving parachute bag is put in the outer lifesaving parachute bag. The outer lifesaving parachute bag and the adult lifesaving back strap are fixedly sewed together. Two branch ends of the lifesaving parachute body connecting belt are connected with parachute rope rings of the lifesaving parachute body, and one branch end is connected with a rear shoulder strap interface of the adult lifesaving back strap. After the lifesaving parachute is expanded fully, by means of generated aerodynamic resistance, a saved person can be decelerated; finally, the person saved under emergency reaches the ground at the steadily-descending speed with the maximum value not greater than 4 m/s; and lifesaving conducted under high-rise emergency can be achieved at the extremely-small injury probability.

Description

technical field [0001] The invention belongs to the technical field of high-rise emergency lifesaving, and relates to a novel high-rise emergency lifesaving umbrella system. Background technique [0002] With the development of the times, the number of high-rise (super high-rise) buildings, as a symbol of the level of urban modernization, is increasing, and the safety of high-rise (super high-rise) buildings is also increasingly concerned by the society. Due to the large number of floors of high-rise (super high-rise) buildings, the people in the building are relatively dense. When sudden disasters such as fires, earthquakes and terrorist attacks occur, the vertical evacuation distance of the people in the building is very long, and the short-term evacuation of people It is very difficult, and it is prone to tragedies such as jumping off the building, falling, and falling to death. Experiments have shown that it takes at least two hours to evacuate all the people in a 50-st...

Problems solved by technology

At the same time, since the direction of personnel evacuation is opposite to the direction of fire spread, people are vulnerable to hazards such as hot air and smoke during evacuation, which increases the danger and difficulty of evacuation.
