Embodiment Construction

[0026] see Figures 1 to 8 , a plane structure schematic diagram and a three-dimensional structure schematic diagram of an automatic dust removal device for civil air defense engineering doors.

[0027] An automatic dust removal device for a civil air defense project door, comprising a wall 1 and a rotating chamber 4, the door 2 is movably installed on the wall 1, the door 1 is provided with an air outlet chamber 9, and the rotating chamber 4 is movably installed with a rotating Disk 5. In a specific implementation, an air inlet 3 is provided on the outer surface of the rotating chamber 4, and a filter screen 14 is fixedly installed in the air inlet 3, and the filter screen 14 is arc-shaped and inclined, so that the dust in the incoming air will be filtered. At the same time, the dust accumulated on the filter screen 14 is blown off to prevent the filter screen 14 from clogging when the airflow enters.

[0028] In the specific implementation, the rotary column 101 is fixedly...

Abstract

The invention relates to the field of civil air defense engineering, in particular to an automatic dust removal device for a civil air defense engineering door body. The automatic dust removal devicecomprises a wall body and a rotating cavity. The door body is movably mounted on the wall body. An air outlet cavity is formed in the door body. A rotating disc is movably mounted in the rotating cavity. Through a moving groove in an equidistant circular wave form is formed in the rotating disc, so that a connecting rod in the moving groove can be rotated around the rotating disc when the door body is used daily, and a squeeze air bag connected with the right end of the rotating disc can be driven to repeatedly move left and right, so that the squeeze air bag generates the air flow to clean the dust; and an air plug with the circular-arc recessed upper and lower sides is arranged at the left end inside an air outlet nozzle at the right end of the squeeze air bag in a recessed manner, so that when the squeeze air bag outputs the air, the acting force generated by the squeeze air bag on the air plug can be stronger, and the air plug can be easily jacked and opened; and meanwhile when theair enters the squeeze air bag, the dust can be blocked and can only be sucked out and cannot be sucked in, so that the purpose of preventing dust from entering is achieved.

Description

technical field [0001] The invention relates to the field of civil air defense engineering, in particular to an automatic dust removal device for a door body of civil air defense engineering. Background technique [0002] The civil air defense project is called the civil air defense project. It is an important facility to prevent sudden enemy attacks, effectively cover personnel and materials, and preserve war potential. In today's civil air defense projects, it is necessary to use closed doors to prevent and resist various disasters. Existing airtight doors generally all are to cooperate and seal by door sill and sealing strip between door frame. [0003] However, there is no cleaning device in the gap between the existing airtight door and the door frame, so it is easy to accumulate dust and dirt in daily use, so that the long-term friction between the sealing strip and the dust will cause damage to the sealing strip, thereby reducing the sealing effect of the airtight doo...
