Movable turnover type protective airtight blocking plate

Abstract

The invention discloses a movable turnover type protective airtight blocking plate. The movable turnover type protective airtight blocking plate comprises blocking plate door leaves, a door frame anda rail mechanism, wherein two walking wheels are rotationally installed at the bottom of each blocking plate door leaf at a certain distance; the door frame comprises a door opening door frame and a door hiding chamber door frame; the rail mechanism comprises a double-rail type lower rail, the length of the lower rail extends from the door hiding chamber door frame to the door opening door frame,and the double rails of the lower rail gradually get close when the door hiding chamber door frame enters the door opening door frame; and the two walking wheels at the bottom of each blocking plate door leaf move along the double rails of the lower rail correspondingly, and the blocking plate door leaves are turned over and unfolded to seal the door opening door frame when the door hiding chamberdoor frame enters the door opening door frame. According to the movable turnover type protective airtight blocking plate, the problems that a protective airtight blocking plate of civil air defense engineering protection equipment is tedious in transportation and installation in wartime, long in conversion time between peacetime and wartime and difficult to install, and a warehouse needs to be occupied when the blocking plate door leaves are stored at ordinary times can be solved.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering protection equipment, and relates to a large-width blocking plate installed at the entrance, exit and communication port of the civil air defense area, and in particular to a mobile flip-type protective airtight blocking plate. Background technique [0002] Civil air defense engineering belongs to combat readiness engineering, which is a function of protecting the life and property of urban people and protecting industrial economic resources when the country suffers from air raids. Civil air defense projects are developed and utilized in peacetime while ensuring combat readiness benefits, so as to obtain higher economic and social benefits as much as possible, thereby promoting the rolling development of civil air defense project construction and urban economic construction. [0003] At present, the commonly used block plate structure is that the block plate door leaf and the...
