Embodiment 1
[0027] Such as figure 2 As shown, a warning device A for preventing cross wind, its structure includes two sets of columns 1, and the upper parts of the two sets of columns 1 are provided with wind deflectors 2 arranged in an array along the vertical direction, and the wind deflectors 2 are all arranged obliquely. The installation height of its outer end is lower than that of the inner end. In this implementation, the upper surface of the wind deflector 2 has an arc-shaped wind deflector surface. After the anti-horizontal wind warning device A is installed on both sides of the bridge, the low end of the wind deflector 2 is located on the outside, and the inclined wind deflector The crosswind can be guided above the carriageway to reduce the influence of the crosswind on the driving vehicles.
[0028] Another example image 3 As shown, an early warning mechanism 3 is provided between the lower parts of two groups of columns 1, and the early warning mechanism 3 includes a bas...
Embodiment 2
[0032] Such as figure 1 As shown, a bridge, the above-mentioned anti-crosswind warning device A is installed on both sides of the bridge, and the spiral anti-crosswind device B is installed at the central isolation zone of the bridge.
[0033] Please refer to image 3 with 4 As shown, in this embodiment, the structure of the spiral anti-crosswind device B mainly includes a support frame 7 , a spiral guide rod 8 , fan blades 9 , a cage 4 and two curtains 5 . Wherein, the supporting frame body 7 is a rectangular frame structure, and a vertically arranged positioning guide rod 7a is provided at each of its two ends. The helical guide rod 8 has a helical surface in the axial direction, and is vertically installed in the middle of the support frame 7 . The fan blade 9 is a propeller structure, which includes a central connection seat 9a and two blades 9b extending radially outward from the central connection seat 9a. The retainer 4 is connected to the lower end of the fan blade...
