Problems solved by technology

The locking mechanism adopts manual control, such as a locking mechanism disclosed in Chinese patent ZL99244380.6 "Protective Airtight Partition Door of Underground Railway Civil Air Defense Engineering". Control operation, long manual operation time and low efficiency
Some schemes using electric motor drive control cannot work reliably in the flooded state
In the prior art, the support of the cantilever end of the vertical-rotating anti-flood protection airtight partition door in the subway civil air defense project and the locking of the fully open position respectively adopt a support device with a fixed height and a scheme of locking after manual operation of a screw jack. The disadvantage is that the support The point has no ability to adapt to the unevenness of the ground, which affects the force of the door hinge. When the ground encounters foreign objects or the ground is higher than the ground at the adjustment point, the door hinge may bear extra thrust and affect normal operation; Requirements for automatic and rapid closing of closed partition doors for flood protection by remote control

Abstract

The invention discloses a control system used for a vertically rotary flood and preventive door, comprising a support locking device, a hydraulic drive device, a monitoring device and a manual and electric locking device. A hydraulic drive system drives a door leaf to open and close. The manual and electric locking device can open and close locks manually and electrically. The support locking device is used for supporting and safely locking the door leaf. The monitoring device is used for monitoring the water level and state of each component and controlling action of each component. The control system 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 a control system for an anti-flooding protective airtight partition door of a subway civil air defense project, in particular to a control system for a vertically rotating anti-flooding protective door. Background technique [0002] In the prior art, the control system of the manual structure of the anti-flooding protection door in the subway civil air defense project generally adopts the traditional manual operation. For example, manual drive is generally adopted, and the main structure is to realize manual control through a gear transmission mechanism or a worm gear transmission mechanism. The schemes of the above-mentioned transmission mechanisms all have relatively large resistance, in order to save labor, the speed of opening and closing the door leaf can only be designed very slowly, and it takes about 5 minutes to open or close once, and it cannot be opened and closed automatically by remote control. The daily maintenan...
