A bridge wind barrier according to claim 1, characterised in that: a second connecting mechanism (5) is arranged on the side walls of the first barrier (2-1) and the bridge body (1); the second connecting mechanism (5) comprises a first connecting plate (5-1), a first fixing plate (5-2), a second rotating shaft (5-3), a second fixing plate (5-4), a second connecting plate (5-5) and a second limiting plate (5-7); a first connecting plate (5-1) is fixed at the bottom of the outer side wall of the first barrier (2-1), a first fixing plate (5-2) is fixed at the outer side wall of the first connecting plate (5-1), and a second rotating shaft (5-3) is inserted and fixed at the inner bottom of the first fixing plate (5-2); a second fixing plate (5-4) is arranged on the front side and the rear side of the first fixing plate (5-2), a second connecting plate (5-5) is fixed at the bottom of the inner side wall of the second fixing plate (5-4), and the other end of the second connecting plate (5-5) is fixed with the side wall of the bridge body (1); the front end and the rear end of the second rotating shaft (5-3) respectively movably penetrate through the front and the rear second connecting plates (5-5), and then a second limiting plate (5-7) is fixed; when the first barrier (2-1) falls, the first barrier (2-1), the first connecting plate (5-1) and the first fixing plate (5-2) all rotate downwards by taking the second rotating shaft (5-3) as a circle center under the action of the first rotating shaft (3-3), so that the first barrier (2-1) is hung on the second connecting plate (5-5).
6. A bridge wind-resistant barrier according to claim 5, characterised in that: a support plate (5-6) is fixed on the inner side wall of the second connecting plate (5-5), and the other end of the support plate (5-6) is fixed with the side wall of the bridge body (1); the supporting plates (5-6) play a role in fixedly supporting the second connecting plate (5-5).
7. A bridge wind barrier according to claim 1, characterised in that: the working principle is as follows: when wind blows, the wind at a higher position blows to the first wind shield (2-3), the wind blows from the second vent hole (2-4), the wind direction is changed, and the first wind shield (2-3) shakes around the hinge (2-7) under the action of the first strong spring (2-5) and the hinge (2-7), so that the impact of strong wind on the first wind shield (2-3) is reduced; wind at a lower position is blown out from a first ventilation hole (2-2) of a first barrier (2-1) firstly, so that transverse wind is changed into oblique upward direction, the wind blows on a second wind shield (3-4), and under the action of a second strong spring (3-5), the second wind shield (3-4) swings up and down by taking a first rotating shaft (3-3) as a circle center, so that wind power is further reduced, the wind is blown out from openings above the first barrier (2-1) and the second barrier (3-1), and wind resistance is realized; when wind blows to the second barrier (3-1), the second barrier (3-1) shakes less under the action of the damping spring (4-3); when the second barrier (3-1) is damaged, the fixing bolts (3-14) are screwed down, the inserting plates (3-8) are pushed outwards, the sliding strips (3-9) move in the second sliding grooves (3-11), so that the inserting plates (3-8) can be pushed outwards stably, the damping springs (4-3) are taken down from the second buckling seats (4-2), the second barrier (3-1) is taken down for replacement, and when the first barrier (2-1) is damaged, the first barrier (2-1) is maintained and replaced after the second barrier (3-1) is taken down.
