Embodiment Construction
[0022] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the drawings are in very simplified form and with imprecise scales, and are only used to facilitate and clearly illustrate the purpose of the present invention.
[0023] Such as figure 1 , 2 , Shown in 3, 4, 5, 6, the present invention is a kind of tornado simulator, and this device comprises electromechanical drive wind control device, air supply duct, tornado generation space, outflow surface. The wind control device is composed of a computer-controlled servo motor and a motor linked with a blower to ensure that the wind speed is input to the tornado occurrence space according to the set function. The inlet connected to the air supply pipe rotates flexibly through the rotating bearing and the windproof brush, so that the inflow wind enters the flow at multiple angles. The space wher...

The invention discloses a tornado simulator. The device comprises an electromechanical transmission wind control device, an air supply pipe, an inflow connection port, a tornado occurrence space, and an outflow surface. The wind control device is composed of a servo motor linked with a blower. By programming the speed function to control the servo motor, the relationship between the motor speed and the wind speed is established to ensure that the wind speed is input to the air supply pipe according to the predetermined method, and the inflow wind in all directions is precisely controlled. The inflow connection port can be flexibly rotated to realize the multi-angle flow of inflow wind into the tornado occurrence space. The tornado occurrence space is made of transparent plexiglass (PMMA) materials, which is easy to install and disassemble. At the same time, the experimenters can directly observe the wind field through the plexiglass. The environment of the tornado wind field simulated by the invention can meet the requirements of engineering tests, and solve the shortcomings of previous artificial tornado simulators that are large in size, difficult to move, and difficult to change in size.
Description
technical field [0001] The invention relates to a tornado simulator, in particular to a convenient and detachable tornado simulator with controllable inflow wind and observable inner space. Background technique [0002] A tornado is a funnel-shaped vortex that appears in a strong convective cloud, with strong destructive power and distinctive features. It is a storm with a central vortex, extreme speed, and spiraling, accompanied by extreme weather such as hail, lightning, and heavy rainfall, which can cause huge damage to infrastructure and buildings, and cause casualties. There are about dozens of tornadoes in our country every year. Tornadoes can be observed in eastern China and Guangdong. The duration of tornadoes in my country is short, about ten minutes, and the moving path is between hundreds of meters to thousands of meters. During the normal use of buildings and infrastructure, the probability of being hit by a tornado is relatively small, but once a tornado occurs...
