A basement air defense door with an anti-collapse protection mechanism and its application method

Abstract

The invention discloses a basement civil air defense door with an anti-collapse protection mechanism, which comprises a vertically arranged door body, an anti-blocking steel plate and an anti-collapse protection mechanism, horizontal end rods are arranged at the upper and lower ends of the door body, and Vertical struts are vertically arranged at both ends of the two transverse end rods, and a hydraulic cylinder 1 is installed obliquely on both sides of the two vertical struts, and a protective plate is connected to the top of the hydraulic cylinder 1 through the extension of the hydraulic column 1. The beneficial effect of the present invention is that the collapsed debris is blocked by the anti-blocking steel plates on both sides above the door body, and the two anti-blocking steel plates are turned upwards at the same time, providing people with a larger area of ​​protection space and greatly improving The safety of the civil air defense door is guaranteed, and the two hydraulic cylinders on both sides above the door body synchronously drive the anti-blocking steel plate to flip upwards, and the two hydraulic columns support it on both sides of the anti-blocking steel plate respectively, ensuring When the anti-blocking steel plate is turned up, the reaction efficiency is faster and more agile, and at the same time, the strength of the anti-blocking steel plate when it is lifted is greatly improved.

Description

technical field [0001] The invention relates to a civil air defense door, in particular to a basement civil air defense door with an anti-collapse protection mechanism and a use method thereof, belonging to the technical field of civil air defense door application. Background technique [0002] Civil air defense doors are indispensable in basements. Civil air defense doors are usually made of high-strength materials with high reliability. Civil air defense doors have excellent protection and airtight performance, and have a good effect of blocking blasting and killing. [0003] Existing civil air defense doors used in basements still have great defects in use. When existing civil air defense doors encounter accidents such as underground collapse and collapse, the protective space that can be provided for people is very limited. The safety of the air defense door is very poor. The strength of the protective parts on the civil air defense door is poor. When the protective part...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the existing civil air defense doors can provide very limited protective space for people when encountering accidents such as underground collapse and collapse, and the security of the civil air defense doors is very poor when they are used; the protection on the civil air defense doors The strength of the parts is poor. When the protective parts block the protection area, the protective parts are easy to collapse and wear, which seriously reduces the safety of the civil air defense door. The safety space that the civil air defense door can provide protection for the human body is small, and the civil air defense door does not have anti The collapse protection function greatly reduces the stability of the support protection; when the civil air defense door encounters emergency accidents such as underground collapse and earthquake, it is very easy to collapse, easy to hurt the human body, and there is a great potential safety hazard.
