The SDBS type mine damper locking device is an important measure for short-circuiting down stream of textiles and ensuring the stability of mine ventilation system. The device adopts a reset type structure. Each end has a section of steel wire rope connected with two air dampers which need to be locked. When a damper is opened, the wire rope is pulled to lock the wire rope of another damper through the locking device; the door closing type locking device is automatically reset. The wire rope is retracted and the two dampers are openable again.
The device completely avoids the short-circuit safety hazard caused by the simultaneous opening of two dampers, ensures pedestrian safety, and is easy to install, reliable, and has high application value.
