Description
Technical field
The method of the device that the present invention relates to a kind of method of control rate and adopt this method, particularly a kind of non-mechanical friction damping automatically controlling speed and device thereof.
Background technology
During the skyscraper breaking out of fire people how safe escape is a problem that does not have fine solution so far.From the method for skyscraper escape, it was the most frequently used method that escape way wherein is set when people had designed a lot of breaking out of fire.But in fact, roaring flame in the fire and poisonous dense smoke often spread in the corridor and escape way of escape way, and panic-stricken survivor is difficult in the extremely low dense smoke of visibility and finds escape way, and the case of this bitterness is too numerous to mention.Some stranded the most direct reaction of people is exactly to run away to window or balcony to call for help and manage escape, can't bear to stand the people that roaring flame engulfs and just jumps off from window or balcony, produces serious casualties.
Various devices from the escape of window or balcony are arranged in the market, and these devices all need the survivor to possess operational capacity to control its decrease speed.In fact this is impossible, because having among the survivor much is weak the elderly, children and the wounded, no matter be the state of mind or muscle power, self-control or operating technology, be in panic-stricken survivor and all be difficult to cool down and operate the escape of this class device effectively.And, these devices nearly all are to come speed limit by mechanical friction, because the size of mechanical friction power changes with the change of various destabilizing factors such as the pressure between the material of friction member, surface physical characteristic, the friction member, environment temperature, humidity, less stable, thus this class to come the escape device of speed limit be unsafe by the mechanical friction damping.
In addition, some work high above the ground and military activity also need the practitioner often to descend from the high-altitude, control its decrease speed though they possess operational capacity, when carrying out professional work, operate again and control its decrease speed, neglect, divert one's attention, slipping up to cause the accident also happens occasionally.
Summary of the invention
One of technical problem to be solved by this invention provides a kind of method of non-mechanical friction damping automatically controlling speed, survivor when making the skyscraper breaking out of fire or be engaged in the speed of work high above the ground personnel in the decline process and be controlled at automatically in the safe range, neither need the user to operate, also be not subjected to the influence of user's muscle power, the state of mind and self-control.
Two of technical problem to be solved by this invention provides a kind of device of realizing said method.
One of technical problem to be solved by this invention can be achieved through the following technical solutions.
A kind of method of non-mechanical friction damping automatically controlling speed is characterized in that: comprise following steps:
