Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of civil air defense engineering, specifically to a civil air defense engineering protective sealing door air leakage detection alarm device. BACKGROUND

[0002] Civil air defense, also known as civil defense, is an activity in which the government mobilizes and organizes the public to take measures to prevent air raids, fight disasters, and implement rescue operations to prevent and mitigate disaster damage. Civil air defense doors are civil air defense protection equipment. Civil air defense doors are the doors of the entrances and exits of people's air defense projects. The air tightness of civil air defense doors is an important quality standard.

The rectangular box is provided with a civil air defense door placing mechanism. The above document still has shortcomings. When in use, the left and right two clamping blocks clamp the civil air defense door. The drive motor drives the rotating shaft to slowly rotate to adjust the position of the civil air defense door. The civil air defense door can be automatically placed on the upper end of the storage frame without manual carrying. Water is injected into the upper part of the rectangular box, and gas is introduced through the air inlet pipe to detect the air tightness of the civil air defense door. However, the device in the above document needs to use an external air pump or air blowing equipment to blow air into the device when detecting air leakage of the protective sealing door.
