[0005] Ventilation duct: Ventilation duct can deliver fresh air to various parts of the mine and discharge dirty air at the same time. The design and layout of ventilation duct has a great influence on the ventilation effect of the mine. The patent announcement number is CN215927445U, which discloses a mine ventilation air-increasing device, including a base and an air-increasing box. The base is provided with a movable column, a shock-absorbing spring, a spring and a limit plate. The spring is fixedly connected to the air-increasing box. The air-increasing box is divided into an air outlet duct, a cavity and an air inlet duct by a partition. The air outlet duct and the air inlet duct are the same structure with opposite directions of internal parts. The air outlet duct and the air inlet duct are both provided with a driven shaft, a driven gear and a fan blade. The air-increasing box is provided with an annular protrusion and a groove. The utility model has a simple structure and is easy to install, disassemble, clean and maintain later. By arranging annular protrusions and grooves on the two opposite surfaces of the air booster box, multiple air booster boxes can be connected end to end to increase the wind pressure in the pipe, speed up the air flow rate, and facilitate the installation of the ventilation duct. By arranging the air booster box in the base, the vibration force generated by the double-headed motor can be dissipated, thereby avoiding damage to the motor and internal parts of the air booster box and affecting their service life.
