A protective door for civil air defense engineering with the function of preventing nuclear radiation

Abstract

The invention discloses a protection door with a nuclear radiation protection function and used for civil air defense engineering. The protection door comprises a protection door main body mounted ina wall body, and the wall body is provided with a mounting chamber; the protection door main body is slidably mounted in the mounting chamber, and a mounting groove is formed in the inner wall of oneside of the mounting chamber; a driving motor is fixedly mounted on the inner wall of the side, away from a groove opening of the mounting groove, of the mounting groove, and a connecting shaft is welded to an output shaft of the driving motor; the end, away from the driving motor, of the connecting shaft extends into the mounting chamber, and a lead screw is welded to the end, away from the driving motor, of the connecting shaft; and a storing chamber is formed in the protection door main body, and the end, away from the connecting shaft, of the lead screw penetrates to the interior of the storing chamber. The protection door with the nuclear radiation protection function and used for civil air defense engineering is convenient to use, the protection door main body can be easily opened through the driving motor, the protection door main body can be conveniently fixed through a double-shaft telescopic motor, by pulling a second magnet, the double-shaft telescopic motor can be conveniently disassembled and maintained, and operation is easy.

Description

technical field [0001] The invention relates to the technical field of protective doors for civil air defense projects, in particular to a protective door for civil air defense projects with the function of preventing nuclear radiation. Background technique [0002] The protective door is set on the outermost side of the entrance and exit, and has two functions of blocking shock waves and isolating poisonous agents. The protective door should be able to block shock waves and meet the corresponding resistance requirements. When selecting, it should not only meet the needs of the size of the opening, but also meet the design pressure requirements. [0003] In the prior art, there is a protective door with anti-nuclear radiation function, all of which are opened manually. Because the protective door itself is heavy, it is difficult to open it manually, and when the protective door is closed, it is fixed by a motor, but It will be inconvenient to repair the motor, resulting in p...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, there is a protective door with anti-nuclear radiation function, which is opened manually. Because the protective door itself is heavy, it is difficult to open it manually, and when the protective door is closed, it is fixed by a motor, but It will be inconvenient to repair the motor, resulting in poor sealing, so we propose a protective door for civil air defense engineering with the function of preventing nuclear radiation to solve the above-mentioned problems
