Description
Technical field
The utility model is related to survival equipment fields, and in particular to slow drop escape device.
Background technology
As China's city size speed expands, the living environment of people turns to based on high-rise building substantially.And
The density of population is higher and higher, and especially in public places, a high-rise building disaster accident especially fire incident is likely to result in greatly
The casualties of amount.And rescue run measure extremely lags, almost into the bottleneck subject for being difficult to crack.
At present substantially without ad hoc fire, rescuing device for earthquake on the skyscraper in China, when fire, earthquake etc. can not
When drag occurs, elevator will be forbidden to use, and Fire lift can only provide fireman reluctantly or delivery fire-fighting equipment uses, largely
Personnel be only capable of going downstairs by escape stair walking, evacuation speed slowly and order be unable to control.In addition, the old,weak,sick and disabled is pregnant to wait spies
Different crowd is very inconvenient using escape stair, and tread event easily occurs, causes casualties.
At present on the market skyscraper evacuation escape device, be broadly divided into descending lifeline (case), escaping rope, escape it is soft
Ladder, slow drop umbrella, slideway etc..Above device is mostly to be hung on the positions such as external wall or balcony outside open or semi-open form,
Interim use is opened when emergency occurs.
But above device the problem is that:1st, user is needed to have good psychological quality and fitness, it is such as slow
Falling unit, the old,weak,sick and disabled is pregnant to wait special populations that can not use at all.2nd, equipment cannot be used for many people simultaneously, may cause people
Member grabs survival equipment, causes sudden hurt accident.3rd, speed is difficult to control, and floor is higher, is reached the speed of bottom and may be got over
Soon, when personnel land, secondary injury may be caused.4th, the safety and reliability of many equipment in itself cannot be guaranteed, such as
The possible deformation failure under the high temperature conditions of some equipment, also some equipment need to power and could work, and fire, earthquake etc. can not
When drag occurs, it is likely that supply of electric power is interrupted, and causes survival equipment unavailable.
Therefore, how existing escape device is improved, make its overcome the above problem be those skilled in the art urgently
A problem to be solved.
Utility model content
, can be simultaneously for more people use the purpose of this utility model is to provide a kind of easy to use, decrease speed can be with
It is controlled automatically in security value (s), safe and reliable the having that can be used in unpowered centrifuges automatic control gear
Slow drop escape device.
To achieve the above objectives, the technical solution adopted in the utility model is:It is a kind of that there is centrifugation automatic control gear
