[0041] Electrical circuit: The electrical mixed gas control box 9 is connected to the middle two-way cylinder through the air duct

[0042] The linkage principle of the damper and the car blocker: When the mine car drives in front of the damper, the vehicle detection sensor 10 is triggered, and the power control box controls the electric mixed gas control box 9 to open the car blockers and the damper on both sides of the damper at the same time, and the mine car passes through the damper normally. After the mine car passes through the damper, the car blocker and the damper are still controlled by the power control box The electric mixed gas control box 9 is closed synchronously.

[0043] Pedestrian detection sensor 4: powered by the control box;

[0044] Vehicle detection sensor 10: powered by the control box;

[0045] Manual conversion switch 11: Power is supplied through the control box.
