Description
Technical Field
The utility model relates to a security protection equipment, in particular to high building dangerous situation device of saving oneself of fleing.
Background
At present, a self-service dangerous case escape device is not arranged in domestic high-rise buildings, and only two escape paths of an elevator and a corridor are provided when a dangerous case occurs. When dangerous situations occur, such as fire or earthquake, one escape path is easy to break down and stops running, and the other escape path is slow in escape speed.
For fire-fighting dangerous situations, the capability of fire-fighting emergency rescue equipment in China is seriously unbalanced with the rapid development of high-rise buildings at present, firstly, the lifting and the long-range shooting capability of the equipment lags behind the high development of the high-rise buildings, the water spraying capability of the existing fire truck is generally 8 floors, the highest aerial ladder truck reaches about 15 floors, and the rescue equipment can only be 'expected to appear in the house'; secondly, the equipment has large volume and poor maneuverability and is easily influenced by road traffic and the surrounding environment of the building; thirdly, the rescue ability of the equipment is not enough, the existing aerial ladder vehicle can only rescue 2 to 3 people by lifting once, and once a fire disaster of a high-rise occurs, the actual rescue requirement on the site can not be met.
Along with the continuous acceleration of the industrialization and urbanization process of China, the contradiction is increasingly prominent, and the existing data shows that the fire accidents of high-rise buildings in developed cities of China are in an accelerated rising situation. In view of the above problems, many high-rise descent control devices have been developed in recent years. However, the conventional high-rise slow-descending device mainly depends on a friction mode to realize slow descending, and cannot be repeatedly used. For occasions with more escape personnel, after the slow descent device is used for multiple times, the safety and stability of the slow descent device are reduced, and the follow-up escape personnel can not escape safely.
