AI Technical Summary
Existing ventilation equipment used in coal mines is difficult to clean impurities from the equipment during ventilation, leading to blockages and reduced ventilation efficiency.
The design incorporates a filtration mechanism and an adjustment mechanism, including a filter plate, springs, cams, a motor, and an electric telescopic rod. Through kinetic energy transmission and mechanical structure design, it achieves impurity filtration and ventilation volume adjustment.
It effectively filters impurities in the air, prevents blockages, maintains the stability and flexibility of ventilation equipment, adapts to changes in mine depth, and avoids insufficient ventilation.
