Shielding device

The embodiment of the invention provides a shielding device, which includes a bracket, a rotating shaft, a shielding plate and a limiting structure. The two ends of the rotating shaft are fixedly connected with the bracket correspondingly, the shielding plate is rotatably connected with the rotating shaft, and the limiting structure is fixedly connected with the bracket for limiting the rotating range of the shielding plate. According to the shielding device, the shielding plate can rotate in the wind direction, the influence of wind power on the whole shielding device can be lowered, meanwhile, the limiting structure can control the maximum rotating angle of the shielding plate, and thus it is ensured that the shielding device has the good shielding effect. By installing the shielding device in the direction perpendicular to a center extension line of an airport runway, airplanes operating on a detour taxiway can be partially or completely shielded, thus pilots can be allowed to better distinguish whether ot
