Traditionally, the anti-wind device used for ventilation during mine operation includes two positions and three positions. The two-position means that the moving contact of the ATSE can only switch between the static contact of the first power supply and the second power supply; the three-position means that the moving contact of the ATSE can stay on the static contact of the first power supply and the second power supply, and can also stay in a double-split position where it does not contact the static contact of the first power supply and the second power supply.

A anti-wind device for ventilation during mine operation, comprising the control circuit as described above.

[0004] This patent simplifies the control circuit of the three-position dual power switch by improving the structure and improving the versatility of the controller. However, for high-voltage equipment, such as 35kv substations, when using the existing anti-wind device for ventilation during mine operations, high-intensity electric arcs are easily generated, which poses a safety risk to the equipment. Therefore, we propose a anti-wind device for ventilation during mine operations. Summary of the invention

Under the action of the ducting fan, the backwind operation is quickly realized. At the same time, the dust suppression agent continuously added by the automatic feeder and the water introduced are quickly stirred by the stirring fan, and the dust suppression liquid is quickly mixed.
