Civil air defense door with radiation protection and sound insulation functions

Abstract

The invention relates to a civil air defense door with radiation protection and sound insulation functions, and belongs to the field of civil air defense doors. The civil air defense door comprises a door frame fixedly arranged on a wall, a civil air defense door body hinged to the door frame, two sealing plates arranged between the civil air defense door body and the door frame, a lifting mechanism arranged between the two sealing plates and used for controlling the distance between the two sealing plates, a radiation protection layer laid on the outer side of the civil air defense door body, and a sound insulation layer laid between the radiation protection layer and the civil air defense door body, wherein the two sealing plates are located on the upper side and the lower side of the civil air defense door body correspondingly; inserting grooves are formed in the top and the bottom of the door frame; the sealing plates are in sliding connection with the civil air defense door body and can be inserted into the inserting grooves; the lifting mechanism is located in the civil air defense door body; the sound insulation layer is fixedly connected with the civil air defense door body and the radiation protection layer; and sealing assemblies used for enhancing the sealing performance between the civil air defense door body and the inserting grooves are arranged between the civil air defense door body and the inserting grooves. The sealing performance of the civil air defense door is guaranteed.

Description

technical field [0001] This application relates to the field of civil defense doors, in particular to a civil defense door with radiation protection and sound insulation functions. Background technique [0002] The civil air defense door is the door of the entrance and exit of the civil protection project. The classification of the civil air defense door is relatively clear. It is divided into single door and double door. It is mainly used to protect the civil air defense command, communication, and shelter personnel from or reduce nuclear, chemical, biological weapons and conventional bombs.

They are suitable for the entrances and exits of various civil air defense projects. However, civil air defense doors are relatively thick. [0004] With regard to the related technologies mentioned above, the inventor bel...

AI Technical Summary

Problems solved by technology

[0003] At present, civil air defense doors have a simple structure, reliable operation, and convenient maintenance. They are suitable for the entrances and exits of various civil air defense projects. However, civil air defense doors are relatively thick. After closing, there are small gaps between the upper and lower sides, and the sealing is difficult to guarantee

[0004] In view of the related technologies mentioned above, the inventor believes that there is a defect that the airtightness of manned doors is difficult to guarantee
