In order to prevent rainwater from affecting the fusing resistance wires 3 around the inflatable air pillow 72, a waterproof material is coated on the surface of the inflatable air pillow 72 meshed with the fusing resistance wires 3.
The specific starting process of the system is as follows:
when a fire disaster occurs, the fire control cabinet breaks off the normally closed contact in the circuit A of the power supply control circuit through the control circuit, the annular electromagnet 18 in the electric and manual integrated electromagnetic lock is powered off, the locking function of the lock tongue 13 is lost, the lock tongue is driven by the elastic restoring force of the restoring spring to return to the unlocking position, and the window sash is quickly opened under the action of gravity, so that the window opening action is completed. The deceleration damping 9 buffers the impact force of opening the window sash, and accidents caused by the damage of the smoke discharging window structure are avoided. Because the lithium battery pack is arranged in the charging management circuit to supply power for the A-path, the windowing operation can be realized even under the condition that all external power sources such as a fire-fighting power source, a municipal power source and the like fail.
