A mobile explosion-proof door for civil air defense engineering

Abstract

The invention discloses a moveable explosion door for civil air-defense construction. The moveable explosion door comprises at least two door planks, a door frame and a slide slot rack, wherein the door frame is welded with the slide slot rack and is fixed on a concrete wall; the door planks are slidably arranged in the slide slots in the slide slot rack through slide blocks; connecting rod locking mechanisms which are used for locking the door planks on the door frame are arranged on the door planks; buffering strips, which can buffer and prevent collision, are arranged at contact edges of the two door planks; the peripheries of the door planks as well as the door plank and the door plank are all locked through the connecting rod locking mechanisms; stopping blocks for limiting the door planks from continuing to move are arranged at the corners of the door frame and the slide slot rack. The invention aims to provide the moveable explosion door for civil air-defense construction, which has a simple structure, is low in cost, is high in strength and can bear the impact force of about 0.8MPa; the explosion door is capable of horizontally moving; the phenomenon that the door body is tightly blocked and people cannot open can be avoided; the explosion door can be applied to the area in larger pore diameter and is wide in application scope.

Description

technical field [0001] The invention relates to the safety field of civil air defense engineering, in particular to a mobile explosion-proof door for civil air defense engineering. Background technique [0002] With the development of air strike weapons, especially high-tech air strike weapons, the destructive effectiveness of air strikes has increased rapidly, and air strikes have become the main means of defeating high-tech powerful enemies. As a result, air defense is not only becoming more and more difficult, but also more and more important. The success or failure of high-tech local wars has become a decisive factor. Although war potential does not appear as direct combat power in normal times, it can be quickly transformed into actual war capability in wartime according to needs. Therefore, war potential is the ultimate determinant of the outcome of a war. In particular, local wars under high-tech conditions, as a contest of comprehensive national strength, are more ...

Problems solved by technology

Technicians found that the existing protective airtight door is opened by a gear transmission mechanism, and the driving gear and the driven gear are installed on the airtight door. When the airtight door is deformed by the bomb impact, it will cause damage to the gear transmission mechanism fixed on the inner surface of the door. Impact damage, and even serious consequences such as gear misalignment and jamming, make the airtight door body unable to open, and civil air defense engineering doors are not only expensive, but also bulky and occupy a large space, with single applicability
