Description

Technical Field

[0001] The utility model relates to the technical field of emergency escape devices, in particular to an escape and rescue device for fire in high-rise buildings. Background Art

[0002] In recent years, serious and vicious fires have frequently occurred in high-rise buildings in my country, which not only caused huge property losses, but also caused huge casualties. Its social impact is bad and has had a great negative impact on residents' psychology and the city's image. The hazards of fires in high-rise buildings are mainly reflected in three aspects: first, the high temperature formed by the fire; second, the toxic and harmful gases produced by the fire; third, the high altitude of high-rise buildings makes it difficult for the victims to escape; at present, the structure of high-rise buildings is becoming more and more complex, and the number of people is becoming more and more dense, so high-rise escape has become an important issue now. In response to this problem, many high-rise escape devices have emerged.

[0003] Small slow-descent escape devices for single or home use have no external protection for the human body during use and are easily attacked by flames, smoke, obstacles, etc. in a fire. In addition, people's psychological fear of heights and the tightening force of the ropes themselves cause pain and casualties in the escape process. Life-saving air cushions may cause casualties because trapped people may jump down before the air cushion is fully inflated. In addition, their use height is limited, only suitable for heights below 20m. After inflation, the air cushion is light and easy to float. The disadvantage of fire elevators installed in high-rise buildings is that when taking the fire elevator to go downstairs, you need to pass through the fire scene instead of avoiding the core area of ​​the fire scene, and power outages are easy to occur during a fire. There are problems. Utility Model Content
