A self-steering type bridge wind barrier for a sea-crossing bridge is disclosed in the invention, and comprises a support, a rotating groove is formed in the side wall of the support, a rotating shaftis rotatably connected into the rotating groove, a wind barrier strip is fixedly connected to the side wall of the rotating shaft, a plurality of pin holes are formed in the inner wall of the rotating groove, and electromagnets are embedded into the pin holes. A strip-shaped groove is formed in the side wall of the rotating shaft, an iron plug pin is connected into the strip-shaped groove in a sliding mode, and the plug pin is elastically connected to the bottom in the strip-shaped groove through a spring. When crosswind comes, the power supply devices in the air inlets in the corresponding directions are made to operate according to the wind direction, the electromagnets in the corresponding pin holes are powered on to attract the iron plug pins to be inserted, and the wind barrier strips can be pulled to rotate to be right opposite to airflow and then fixed, so the crosswind blown to a bridge can be blocked by the maximum windward side all the time, and the safety protection effectof the bridge wind barrier is greatly improved.
本发明公开了一种用于跨海大桥的自转向式桥梁风障，包括支架，所述支架的侧壁上开设有转动槽，所述转动槽内转动连接有转轴，所述转轴的侧壁固定连接有风障条，所述转动槽的内壁上开设有多个销孔，所述销孔内嵌设有电磁铁，所述转轴的侧壁开设有条形槽，所述条形槽内滑动连接有铁制的插销，所述插销通过弹簧弹性连接在条形槽内底部。本发明通过在侧风袭来时，根据风向来使对应方向进风口内的供电装置运转，并使对应销孔内的电磁铁通电而吸引铁制插销插入，可拉动风障条转动至与气流正对后再固定，从而能够始终以最大迎风面来阻挡吹向桥梁的侧风，大大提高了桥梁风障的安全防护效果。
