Abstract

The invention relates to the technical field of civil air defense engineering, and discloses a ventilation filter device for civil air defense engineering, which includes a cylinder, and retaining rings are integrally formed on the left and right sides of the cylinder, and the retaining ring on the right side A second motor is provided at the inner center of the motor, the output shaft of the second motor is fixedly connected with a connecting ring, the outer side wall of the connecting ring is fixedly connected with a fan-shaped disk, and the inner side wall of the connecting ring is rotatably connected with a circular shaft, The outer wall of the circular shaft is fixedly connected with a disk; the improved air exchange filter device can adjust the size of the ventilation, and can completely close or fully open the ventilation opening on the right side of the cylinder, and can perform ventilation or sealing operations according to specific conditions. The rotation of the fan-shaped disk can cover all the air holes, and the fan-shaped disk and the air holes are interlaced to adjust the air flow of the air holes. Moreover, due to the design of the first motor, the screw seat, and the telescopic frame, the disk can slide to the right or Slide it up to fully open the cylinder vent.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, in particular to a ventilation filtering device for civil air defense engineering. Background technique [0002] The civil air defense project is also called the civil air defense project. It is an underground protective building built separately to protect personnel and material shelter, civil air defense command, and medical rescue in wartime, and a basement that can be used for air defense in wartime when combined with ground buildings. [0003] The civil air defense project is an important facility to prevent sudden enemy attacks, effectively cover personnel and materials, and preserve war potential; it is an engineering guarantee to persist in urban combat and long-term support for anti-aggression wars until victory. Drinking water pipelines, power grids and air exchange filtering devices are installed in the civil air defense project, which can ensure that the people c...
