Description

[0002] In mine production operation, the ventilation system plays a key role in guaranteeing the safety and comfort of the underground operation environment. As an important part of the ventilation system, the ventilation window mainly functions to regulate the air distribution in the underground ventilation network to meet the demand of fresh air in different operation areas, and effectively discharge harmful gases and dust.

[0003] At present, the traditional mine ventilation window device mostly adopts fixed opening or manual adjustment. In the actual mine environment, the wind force is complex and changeable, and is affected by many factors such as the advance of the underground mining operation face, the change of the ventilation equipment operation state and the change of the geological conditions. The wind force in different areas of the mine fluctuates all the time. However, the existing ventilation window cannot automatically adjust the opening size of the window blade according to the real-time wind force in the mine. This limitation leads to that when the wind force is large, the window cannot timely reduce the opening, so that the air volume in some areas is too large, not only causing waste of energy, but also possibly causing wind flow disorder and affecting the stability of the ventilation system; and when the wind force is small, the window cannot automatically increase the opening, leading to insufficient air volume in some operation areas, which cannot effectively dilute harmful gases and poses a threat to the life safety of the underground operation personnel.
