[0004] However, the disadvantage of this ventilation arrangement is that since the dampers are basically set in a high negative pressure state, the pressure difference on both sides of the damper is relatively large, which makes it very laborious to open the damper, which is not conducive to the passage of personnel.
Sometimes, it is also easy to cause a damper injury accident
Even if the see-through pressure relief window is used together with the ordinary damper, it is difficult to open the damper normally, and generally multiple people are required to jointly open the damper or increase the number of groups of the damper
This will cause the disadvantages of complicated structure, difficult operation and high cost.

The invention provides an air door for a mine, which comprises a door leaf, a door frame and an air door opening device. The door frame matches with the door leaf, the air door opening device is arranged on the door leaf and the door frame, the air door opening device comprises a Z-shaped connecting rod, a base disc and a fixing slide board, the Z-shaped connecting rod is used for opening the air door and comprises a draw rod long arm, a connecting rod short arm and a connecting rod center shaft, the draw rod long arm and the connecting rod short arm are respectively located at two ends of the Z-shaped connecting rod, the connecting rod center shaft is connected between the draw rod long arm and the connecting rod short arm, the base disc is provided with a connecting rod shaft sleeve used for fixing the connecting rod center shaft, so that the connecting rod center shaft is driven to rotate in the connecting rod shaft sleeve under the effect of the draw rod long arm, and the fixing slide board is used for holding the tail end, which is not connected with the connecting rod center shaft, of the connecting rod short arm, and the tail end of the connecting rod short arm is driven to slide in the fixing slide board under the effect of the draw rod long arm and applies pressure to the fixing slide board. The air door for the mine is simple in structure and is labor-saving and convenient in opening.
Description
technical field [0001] The invention relates to the field of mine ventilation, in particular to a mine damper. Background technique [0002] In the field of mine production, the ventilation system is an important guarantee for mine safety production, and the damper is one of the important ventilation facilities in the ventilation system. [0003] In the existing mine ventilation system, in order to effectively distribute the air volume and balance the pressure, it is generally necessary to set a damper between the air inlet tunnel and the air return tunnel. In addition, a see-through pressure relief window can also be set on the damper. [0004] However, the disadvantage of this ventilation arrangement is that since the dampers are basically set in a high negative pressure state, the pressure difference on both sides of the damper is relatively large, which makes it very laborious to open the damper, which is not conducive to the passage of personnel. Sometimes, it is also...
