Barrier opening system for emergency escape and rescue
A barrier opening system for emergency escape and rescue comprises a vertical acting barrier device, an escape device, and a rescue device, the vertical acting barrier device winds a barrier via a winding shaft; a prestressed spring preloaded on the winding shaft for storing a restoring force when the barrier is unwound by the winding shaft; a brake mechanism for stopping the winding shaft from rotating; a brake release mechanism for releasing the winding shaft under an abnormal condition; an escape device comprising an identification unit and a master key for activating the brake release mechanism; the identification unit identifies a rescue personnel's identity before allowing the personnel to use the master key to activate the brake release mechanism; when the emergency button and/or the master key activate(s) the brake release mechanism to release the winding shaft, the barrier can be lifted up by the restoring force.
