A kind of air defense basement

Abstract

This application relates to a civil air defense basement, which includes a basement body, an entrance is opened on the basement body, a manned air defense door is slid on the inner side wall of the basement body, and a driving mechanism for driving the air defense door to move is arranged on the basement body, the driving mechanism includes a first chain Wheel, drive motor, second sprocket, locking assembly; the first sprocket is set on the basement body for rotation, the drive motor is set on the basement body, the second sprocket is set on the output shaft of the drive motor and connected with the first sprocket through the chain The sprocket is connected, the air defense door is connected with the chain, and the locking assembly is arranged on the basement body to fix the chain. This application drives the civil defense door to move by driving the motor to open or close the civil defense door. After the movement is completed, close the locking assembly to fix the position of the civil defense door, so there is no need to manually turn the civil defense door, which saves time when opening or closing the civil defense door save effort.

Description

technical field [0001] The present application relates to the technical field of basements, in particular to an air defense basement. Background technique [0002] Civil air defense basement is an important part of civil air defense engineering, including exterior walls, buffer walls, explosion-proof doors and other parts. In normal times, it can be used as spare rooms such as underground parking garages to solve the increasingly prominent problem of parking difficulties; it is used in wartime It also takes into account fortification projects, professional air defense team projects, second-class personnel shelter projects, etc. [0003] In the prior art, you can refer to the Chinese invention patent whose application publication number is CN109594835A, which discloses a civil air defense basement that takes into account both peacetime and wartime ventilation. The side wall of the shaft is provided with rain-proof aluminum alloy shutters; one side of the shaft is provided wi...

AI Technical Summary

Problems solved by technology

[0004] For the related technologies mentioned above, the inventor thinks that there are the following defects: the civil air defense door in the civil air defense basement is in order to prevent the violent impact of the outside world, because the civil defense door is relatively heavy, so it will be time-consuming and laborious when opening or closing the civil defense door
