[0054] Compared with the prior art, the vertical cylindrical tornado test device provided by the present invention has the following beneficial effects:

[0055] A vertical cylindrical tornado test device provided by the present invention comprises a base 10, two air guide components 20, a first driving member 30, two blowing components 40 and a flame generating component 50. The two air guide components 20 are respectively provided with air guide surfaces on the opposite sides thereof, and the air guide surfaces are semi-cylindrical surfaces or semi-conical surfaces. The two air guide surfaces are arranged at a certain distance from each other in the direction of the first track 11, and the airflow blown by the blowing component 40 flows along the air guide surface to the tornado forming area to generate a tornado. The flame generating component 50 is arranged on the air guide component 20, and can provide flames to the tornado forming area, thereby forming a fire tornado.

[0056] In the present invention, two wind guide surfaces enclose a tornado formation area that is approximately cylindrical or approximately conical, and two blowing components 40 are respectively arranged away from the tornado formation area. On the one hand, the wind guide surface can guide the airflow blown by the blowing component 40 to generate a tornado in the tornado formation area, and on the other hand, it can also limit the range of the tornado, especially the fire tornado, to prevent the flame from escaping the area. The two blowing components 40 are respectively arranged on the side of the wind guide component 20 away from the tornado formation area, and are not easily damaged by the high temperature of the flame. The first driving member 30 can adjust the horizontal position of the wind guide component 20, thereby adjusting the diameter range of the tornado formation area to meet different test requirements.
