Device, the relay in driving power expander then drive entrance to a lane high and low voltage switch, implement power-off to non-intrinsic safety electric source in lane and close
Lock.
The multifunctional monitoring device includes Multifunctional monitor and entrance to a lane Multifunctional monitor in lane；The air door switch
Sensing device connects Multifunctional monitor in lane by monitoring circuit, in the lane Multifunctional monitor also by monitoring circuit with
Entrance to a lane Multifunctional monitor connection, entrance to a lane Multifunctional monitor are connect by monitoring circuit with power extension device.
The air door switch magnet distance of tongue tube and lower section in air door switch sensing device is closer, and magnet magnetic force can make
Tongue tube is closed, and circuit is connected, and generates a normally off signal at this time, and Multifunctional monitor senses that normally off is believed in lane
Number be in normal condition；When deficiency in draught or calm air duct, the right half transmission circle of Wind tunnel sensor falls, air door switch magnet with
Tongue tube distance in air door switch sensing device becomes larger, and magnet magnetic force can not be such that tongue tube is closed, and circuit disconnects, and generates at this time
One normally opened signal, Multifunctional monitor sends out sound-light alarm after sensing normally opened signal in lane, and will be believed by monitoring circuit
Number it is transmitted to entrance to a lane Multifunctional monitor, entrance to a lane Multifunctional monitor simultaneously transmits a signal to power extension by monitoring circuit again
Device, the relay in driving power expander then drive entrance to a lane high and low voltage switch, implement power-off to non-intrinsic safety electric source in lane and close
Lock.
Multifunctional monitor is also connected to downhole monitoring center by monitoring circuit in the lane.It will be believed by monitoring circuit
Number it is transmitted to monitoring center, is shown on monitoring display screen curtain, it being capable of effectively each headwork under monitoring center inspection well
The wind tube wind quantity situation of change in face.
The utility model has the advantages that compared with prior art：
The utility model can effectively monitor wind tube wind quantity, and can send out sound-light alarm in deficiency in draught and cut off pick
Non- intrinsic safety electric source in into working face implements locking；And monitoring center is transmitted a signal to by monitoring circuit, it is aobvious to be shown in monitoring
On display screen curtain, can effectively under monitoring center inspection well each driving face wind tube wind quantity situation of change.
