 The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but it should be noted that these embodiments are only used to illustrate the solutions of the present invention, and should not limit the scope of the present invention thereto.
 Such as figure 1 As shown, the annular backflow vertical wind tunnel of the present invention has the following parts: a lower power system 1 , a casing 2 , a bracket 3 , a working tunnel body 4 , and a backflow deflector 5 . The following describes the working principle of the system for these parts respectively.
 In this embodiment, the power system of the present invention is different from the top-mounted power system of the existing wind tunnel, but the power system 1 is placed at the bottom of the entire vertical wind tunnel. Compared with the top-mounted power system, the advantage of this design is that Not only can the weight and vibration carried by th...
