Remote automatic enclosed system for coal mine

The utility model relates to a remote automatic enclosed system for a coal mine. The enclosed system is characterized by comprising automatic enclosing devices that are respectively arranged in an intake airway and a return airway of a mine, and pneumatic switches that are arranged in a main intake airway and corresponding to the automatic enclosing devices. According to the remote automatic enclosed system for the coal mine disclosed by the utility model, the automatic enclosing devices push, through high-pressure air, pistons arranged in pneumatic mechanisms to move in fixed rods, since the pistons are connected with movable rods and explosion-proof material plates are arranged on the movable rods, the explosion-proof material plates arranged at the bottom ends of the movable rods drive, through the action of gravity, other explosion-proof material plates to slide downward, thereby forming airtight separation and preventing air from entering, and further achieving a purpose of isolating oxygen; when the automatic enclosing device is not needed for use, the explosion-proof material plates are put away, so that a small space is occupied, use is convenient, and normal production is not affected; the remote automatic enclosed system can be widely applied to fields of temporary enclosing, permanent enclosing and the like, of mined-out areas of the mine.
