Road warning sign for expressway
The road warning board comprises two stand columns, functional blocks are slidably connected to the side walls of the opposite sides of the two stand columns through mounting grooves, first springs are fixedly connected between the functional blocks and the stand columns, a warning board body is jointly welded to the side walls of the functional blocks, and two through holes are formed in the warning board body. Each functional block is of a hollow structure, the inner side wall of each functional block is rotationally connected with an electromagnet through a rotating rod, a torsion spring is arranged at the rotating joint of each electromagnet and the corresponding functional block, a magnetic plate is glued to the inner bottom wall of each functional block, and a permanent magnet is arranged in each stand column. The crosswind warning sign has the advantages that the windward area of the warning sign can be reduced during crosswind, so that wind resistance is reduced, the height can be reduced when wind is too large, the gravity center is lowered, the crosswind is effectively prevented from toppling over, safety is high. Meanwhile, the wind direction can be indicated, and a driver who is about to enter a crosswind area can make preparations in advance.
本发明公开了一种高速公路用道路警示牌，包括两个立柱，两个所述立柱相对一侧的侧壁均通过安装槽滑动连接有功能块，所述功能块与立柱之间固定连接有第一弹簧，所述功能块侧壁共同焊接有警示牌，所述警示牌开设有两个通孔，所述功能块为空心结构且内侧壁通过转动杆转动连接有电磁铁，所述电磁铁与功能块的转动连接处设置有扭力弹簧，所述功能块内底壁胶合有磁性板，所述立柱内均设置有永磁体。优点在于：本发明中的警示牌可以在横风时减小自身迎风面积，从而减小风阻，且可以在风力过大时降低高度，从而降低重心，有效的防止横风使其倾倒，安全性较高，同时可以指示风向，使得即将进入横风区域的司机提前做准备。
