Description

Wind distributing device of wind tunnel terminal air outlet Technical Field The utility model relates to the technical field of underground ventilation of coal mines, in particular to an air distributing device of an air outlet at the tail end of an air duct. Background In underground coal mine operation, a ventilation system is one of key links for guaranteeing the safety and production efficiency of miners. The air duct is used as an important component of the ventilation system and is mainly used for introducing air flow generated by ventilation equipment on the ground into an underground working surface so as to dilute and discharge harmful gas and dust in a mine, and simultaneously regulate underground temperature and humidity to create a safe and healthy working environment for miners. However, in actual use, only depending on a single air outlet at the tail end of the air duct, the air quantity is concentrated in the area right in front of the air outlet, and the air flow is unevenly distributed, so that the ventilation efficiency is reduced and the energy consumption of the ventilation equipment is increased.
