Problems solved by technology

Existing tornado simulators can only simulate tornadoes with a single vortex ratio. If you need to study tornadoes with other vortex ratios, you need to replace the deflector and base, which is very cumbersome

Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with specific embodiments.

[0029] A multi-vortex ratio tornado simulator, comprising a simulator body 10, the simulator body 10 is provided with a deflector 11, and the simulator body 10 is also provided with an angle adjustment mechanism for adjusting the angle of the deflector 11 so as to change the swirl ratio .

[0030] To further optimize the above embodiment, the angle adjustment mechanism includes a rotating hoop 121 that can rotate along its own axis, and the end of the deflector 11 away from the axis of the rotating hoop 121 is rotatably connected to the main body 10 of the simulation device, and the deflector 11 It is also connected with the rotating hoop 121 so that the rotation of the rotating hoop 121 drives the change of the angle of the deflector 11 .

[0031] To further optimize the above embodiment, the ring wall of the rotating hoop 121 is provided with a first through hole 1211,...

Abstract

The invention belongs to the field of wind fields, and in particular relates to a multi-eddy current ratio tornado simulation device. A multi-vortex ratio tornado simulation device, comprising a simulator body, the simulator body is provided with deflectors, and the simulator body is also provided with an angle adjustment for adjusting the angle of the deflectors so as to change the swirl ratio mechanism. The beneficial effects of the present invention are: the present invention sets an angle adjustment mechanism for adjusting the angle of the deflector in the simulation device body, and changes the speed direction of the airflow entering the plexiglass cover through the angle adjustment mechanism, thereby changing the vortex ratio of the tornado. The rotation of the angle adjustment mechanism drives the deflector to rotate together, avoiding the complicated steps of adjusting the deflector separately and reducing the error of manual adjustment. The wind speed of the exhaust fan can be measured, the angle scale is set in the arc groove, the inflow angle can be read, and the height of the inflow area is also known, so that the swirl ratio can be calculated, and the replacement of the deflector and the base can also be avoided.

Description

technical field [0001] The invention belongs to the field of wind fields, and in particular relates to a multi-eddy current ratio tornado simulation device. Background technique [0002] The wind disaster caused by tornado is a relatively serious form of wind-induced disasters. It has the characteristics of strong suddenness and amazing destructive power, and often has hail, lightning, heavy rainfall, etc., causing huge damage to building structures and heavy casualties , is one of the important prevention objects of wind resistance and disaster reduction projects. Because tornadoes generally occur in open areas, the main damage objects are low buildings, so the research on the tornado resistance of low buildings is of great significance. Existing tornado simulators can only simulate tornadoes with a single vortex ratio. If you need to study tornadoes with other vortex ratios, you need to replace the deflector and base, which is very cumbersome. Contents of the invention ...
