AIR DOOR USED FOR CONTROLLING THE AIR FLOW IN UNDERGROUND MINES

摘要

The invention is a new air door (1), to be used in the underground mines and similar enterprises, for sending required amount of air in the required area in the underground mine when there is no transportation, for providing easy direction of the air by increasing the strength of the airway, for creating a sectional area to be used for transportation by means of moving on each other when there is transportation, characterized in that; it comprises at least one frame (11) which can be opened and closed with 0 - 90° angle for allowing the passage in case of need, it comprises many wings (12) which are located in said frames (11), makes air derationing by increasing the resistance of the airway by making rotational movement with 0 - 180° angle, it comprises many shafts (13) which engage said wings (12) in the frame (11) and allows said wings (12) to rotate around its axis.
