Movable windbreak for bridge

The invention discloses a movable windbreak for a bridge, and relates to a bridge technology. The movable windbreak comprises a plurality of movable windbreak units which are sequentially and linearly arranged along the bridge towards both sides of the bridge floor, wherein each movable windbreak unit comprises a movable windbreak face, a special driving mechanism, a bracket and a base. The movable windbreak for the bridge can effectively ensure the driving safety on the bridge under crosswind conditions, raise the ambient wind speed for driving on the bridge, effectively ensure the wind resistance safety of a major bridge structure after the windbreak is arranged, and effectively lower the cost of the major bridge structure in the aspect of wind resistance design.
