The invention discloses a dust collection device for a road. The dust collection device comprises a
speed reduction band. A
water storage cavity is formed in the position, on the lower side of the
speed reduction band, of a roadbed. A u-shaped structure is adopted by the
water storage cavity. A containing opening is formed in the upper end of the
water storage cavity. Drainage pipelines and
dust fall pipelines communicating with the drainage pipelines are symmetrically arranged in the water storage cavity. An overflow opening is formed in one side of each drainage pipeline. The dust collectiondevice has the advantages that when the
speed reduction band is automatically stored and restores, a middle
piston greatly reduces load gravity through incompressible static fluid, acting force is transmitted to a left
piston and a right
piston, the left piston drives a dust collection piston through a left
piston rod to do the exhaust and suction
stroke, the right piston drives a water suction piston through a right
piston rod, a synchronous rod and a driven
piston rod to do the water suction and drainage
stroke, non-raised too high dust on the road is sucked into the
dust fall pipelines tobe subjected to
dust fall treatment, the dust is prevented from polluting the environment, and the body health of pedestrians is protected.
