AI Technical Summary
The existing fireproof partition door system cannot close properly when the rail vehicle loses power, resulting in the failure of the safety protection function, the inability to effectively isolate dangerous areas, and the threat to passenger safety.
A fireproof partition door system was designed, including a track assembly, a door leaf assembly, a drive assembly, a reset winch, and a control assembly. The reset winch automatically closes the door in the event of a power outage. Combined with the cooperation of electromagnetic and elastic components, the system ensures that the door leaf can automatically close when the power is off.
When the rail vehicle loses power, the fireproof partition door can automatically close, ensuring passenger safety and preventing the door from failing to close due to power failure, thus improving safety in emergency situations.
