Multiple air outlets across support plate, both sides of the road are equipped with drainage ditch, the well lid with road level, road are equipped on drainage ditch
Two sides are equipped with fume extractor, and the fume extractor includes gas gathering mask, exhaust fan, spray tube, exhaust pipe, resisting blower and smog
Alarm, the gas gathering mask are embedded in the tunnel of both sides of the road, and gas gathering mask adds close to the upper, middle and lower of road side
Work has exhaust outlet, and exhaust fan is equipped in exhaust outlet, and the spray tube is mounted at the top of gas gathering mask, is machined with and collects on spray tube
The spray head of gas hood connection, gas gathering mask bottom are connected to drainage ditch, and there is the side of adjacent gas gathering mask lower part at the both ends of exhaust pipe respectively
Wall connection, exhaust pipe is interior to be equipped with resisting blower, and the exhaust pipe of resisting blower air outlet side is equipped with ozzle, the smog
Alarm is mounted on the bottom surface of support plate.
Shield is installed on the exhaust outlet of the gas gathering mask.
It is machined with multiple sumps being uniformly arranged on the drainage ditch, is equipped with liquid level sensor in sump.
The present invention has the effect that
(1) by setting fume extractor, the smog that can rapidly generate fire is discharged, to avoid the full tunnel of smog product,
The case where influencing tunnel light, and avoiding anoxic in tunnel generation；
(2) by processing exhaust outlet in the upper, middle and lower of gas gathering mask, the flue gas that can quickly generate fire is arranged
Out.
