The slope height L on the slope of the first wind deflector unit and the slope of the second wind deflector unit is 5m, slope angle θ is 15 ° ~ 60 °.
Described first wind deflector unit and the second wind deflector unit are arranged axisymmetricly relative to the obstruction that keeps out the wind.
Described first wind deflector unit and the second wind deflector unit near the side of the obstruction that keeps out the wind all with keep out the wind bar contact or partly overlap.
The described obstruction that keeps out the wind is the king-post on bridge, and described road surface is the road surface on bridge.
Also comprise mounting bracket, described mounting bracket is provided with slot, and each baffle plate is plugged in described slot.
The beneficial effects of the utility model are, beam wind air ducting of the present utility model, only need add air partition blocking near the obstruction that keeps out the wind (such as king-post) of beam wind, avoid the safety problem that vehicle breaks away because beam wind suddenly disappears, rolls, cost is lower and the set-up time is short; The slope of beam wind air ducting is from the obstruction that keeps out the wind, along road surface bearing of trend to the direction away from the obstruction that keeps out the wind, gradually downwards near the road surface that vehicle travels, thus from the obstruction that keeps out the wind, reduce the size of the baffle plate blocking beam wind gradually, beam wind is increased gradually to both sides with baffle plate from the obstruction that keeps out the wind, avoids beam wind suddenly disappear at obstruction place of keeping out the wind and affect normal vehicle operation; The slope size of beam wind air ducting and the geomery of baffle plate and arranging situation can adjust according to factors such as the width of concrete meteorological condition and king-post, realize the effect of even wind current stabilization.
