Hydraulic vertically rotary airtight flood and preventive partition door in metro running

Abstract

An airtight flood and preventive partition door used for civil defense in metro running mainly comprises a door leaf, a door frame, a hinge, a hydraulic drive device, a manual and electric locking device, a manual gate valve, a manual and electric gate valve, a support locking device, a monitoring device and the like. A hydraulic drive system drives the door leaf to open and close. The manual andelectric locking device can open and close the locks manually and electrically. The gate valve is used for sealing a drainage ditch passing by the partition door. The support locking device is used for supporting and safely locking the door leaf. A monitoring system is used for monitoring the water level and state of each component and controlling action of each component. The partition door simultaneously satisfies the requirements of civil defense and flood standards, is suitable for the characteristics of the metro running structure, occupies little space, has low overall cost, is characterized in that all the components can be used manually and electrically, can be monitored remotely and opened and closed easily and quickly, and has higher application value.

Description

technical field [0001] The invention relates to an anti-flooding protective airtight partition door used for civil air defense projects in subway sections, in particular to a vertically rotating protective airtight partition door that is hydraulically driven, capable of remote monitoring, and anti-flooding. Background technique [0002] In the prior art, the protective airtight partition door and the anti-flooding door in the civil air defense project of the subway section across the river are generally installed separately, occupying a lot of civil engineering space, and the cost is high, and many places have small spaces and cannot be installed separately. If combined settings, the requirements of civil air defense and flood prevention cannot be met at the same time. For example, the civil air defense partition door is generally manual or electric lifting type, the manual type does not meet the electric requirements for flood prevention, and the electric lifting type needs...

Problems solved by technology

[0002] In the prior art, the protective airtight partition door and the anti-flooding door in the civil air defense project of the subway section across the river are generally installed separately, occupying a lot of civil engineering space, and the cost is high, and many places have small spaces and cannot be installed separately

If combined settings, the requirements of civil air defense and flood prevention cannot be met at the same time

For example, the civil air defense partition door is generally manual or electric lifting type, the manual type does not meet the electric requirements for flood prevention, and the electric lifting type needs to occupy the space of the upper and lower floors, and the scope of application is limited; the ordinary flood prevention door can be electric, but it does not meet the requirements of the flashlight for civil air defense. Use, air tightness requirements, occupy a large space
