There is a pressing problem in the design of high-rise apartments and towers during the occurrence of the events like explosion, fire, earthquake since the inhabitants are not able to get out of the building and they get trapped in the dangerous situations. Currently all around the world, there are some systems but they have not met the urgent requirements and we annually witness lots of death tolls caused by fire and explosion. In order to remove the above-mentioned deficiencies, a new system has been designed which creates the possibility of transferring people from heights to the downside of the apartment in emergency conditions without requiring any energy. The device works by converting the potential gravitational power of weight into kinetic and heat energy. This operation is done by controlling and converting the function of a variable and invariable hydraulic pump or hydro motor which is connected to two grooves spool and the pump outlet is controlled by a control valve and centrifugal governor. The control operation causes the spool steel wire to be slowly opened. Consequently the person descends. This system works like a hydrodynamic damper.
1- Fabrication of rescue system from highly-elevated buildings using automatic hydrometrical control which is operator and energy free, consists of the following items:
Rescue system from highly-elevated apartment consists of a system exciter which is a standard hydraulic plunger pump (open loop) with three plungers (17) and three cylinders (19) that each cylinder has separate inlet check valve (28) and outlet check valve (20). All of which are enclosed in the common casing (38) that crankshaft (14) and parts are lubricated with oil.
According to claim 1:
Rescue system from highly-elevated buildings using automatic control, the landing velocity of the user is analyzed and controlled via four specific systems. This system consists of three valves (23-24-25) for analyzing purposes, flow and hydraulic pressure control and a Variable Centrifugal governor with ability to change the speed of reaction (33) to analyses the landing velocity.
