The invention discloses a novel intelligent control system for an underground air door, and belongs to the technical field of intelligent control of underground air doors. The intelligent control system for the underground air door comprises an air door body, a main control box, an electric control box, a pneumatic control box and an infrared correlation switch, wherein the air door comprises an air door A and an air door B; the air door A and the air door B mainly comprise door frames, door shafts and door leaves; a pneumatic control locking system comprises an air path a and an air path B; the air path a and the air path B are the same in structure; and each of the air path a and the air path B comprises an air cylinder, a two-position five-way double-air control scavenging air valve, atwo-position five-way electromagnetic valve, a two-position three-way single-air control valve, a two-position three-way electromagnetic valve, a shuttle valve and a pneumatic button. According to thenovel intelligent control system for the underground air door, the automation of the underground air door is realized, the reliability and the safety of the air door are enhanced by two electric modes, and the accidents that people are clamped by the air door and are collided by the air door are effectively avoided.
Description
Technical field: [0001] The invention belongs to the technical field of intelligent control of downhole dampers, in particular to a novel downhole damper intelligent control system. Background technique: [0002] The damper is a common ventilation facility in the mine ventilation system, mainly used in the roadway that cuts off the wind flow and allows vehicles and personnel to pass through. The "Coal Mine Safety Regulations" clearly stipulates that at least two normally closed air doors must be installed in some underground tunnels. When pedestrians and vehicles pass, some air doors should be opened and some air doors should be closed. When a mine disaster occurs, if the gas protrudes, it is easy to cause the damper to be damaged. In addition, due to misoperation or poor management, the damper may also be opened. These situations will cause the air flow in the mine ventilation system to be disordered, which may cause mine disasters or secondary the occurrence of disasters....
