The country's first fire tornado science popularization exhibition.
The flame is 5 meters high, covered with "dragon scales", and the maximum temperature can reach ...... 1000 degrees CelsiusIn order to enrich the form of fire warning education, the country's first fire tornado science popularization exhibition was re-launched in the Hefei Science and Technology Museum "Dragon". In addition, the Hefei Science and Technology Museum also "new" a lot of popular science exhibits, such as high-altitude bicycles, balance juggling robots, outdoor water worlds, etc. On February 21, the reporter will take you to grab the "fresh" to take a look!
The first in the country, "Dragon" reappeared.
On February 21, the reporter came to the museum area, just went to the second floor, and did not see the real body of the exhibition item, so he followed the smell of kerosene to find the fire tornado.
The fire tornado exhibit is located in the southwest hall on the second floor of the museum area, and the smell of kerosene that the reporter smelled is the "trace" left by the fire tornado just after the exhibition. In front of the reporter's eyes, there is a 5-meter-high rectangular transparent device, the operator through the start button, the fire tornado will burn rapidly in the device, high-speed rotation, layers of flames like dragon scales.
Cao Xiaoxiang, deputy director of the exhibits research and development department of the Hefei Science and Technology Museum, told reporters that the fuel for the fire dragon scroll exhibition is kerosene, and they use automatic combustion devices to manufacture each fire dragon exhibition, with a flame height of up to 5 meters and a maximum temperature of 1,000 degrees Celsius.
In daily life, fire tornadoes are extremely rare, it is also known as a fire tornado, fire monster, fire whirlwind, etc., is a cyclone formed by flame and smoke in extreme heat and wind conditions, the height varies from tens of meters to several kilometers, and the core temperature can be as high as thousands of degrees Celsius.
Through this exhibition, we not only want to lead you to see the magic of the power of nature, but also hope to bring fire warning to everyone. Cao Xiaoxiang explained that fire tornadoes are often accompanied by natural disasters such as volcanic eruptions, ** occurrences or fires. That's why electric vehicles aren't allowed to be parked in high-rise buildings.
The stairwells of high-rise buildings are prone to the formation of a chimney effect, coupled with the continuous entry of cold air into the windows between the floors, once the electric car catches fire, a strong fire tornado will be formed, which will quickly rise into the air and burn. Cao Xiaoxiang said that in order to install this exhibition, as early as 2020, when the new museum was built, they included the fire tornado exhibition into the curatorial planning, and did a good job in the second floor area in advance of fire protection, smoke exhaust and other safety designs.
In January this year, the installation and testing of the Fire Dragon Roll exhibition was completed, and it was officially opened for the first time on February 12. At present, the demonstration time of the fire dragon scroll exhibition is still dynamically adjusted, and interested citizens and friends can pay attention to the WeChat of Hefei Science and Technology Museum to learn about the specific exhibition time.
A number of new exhibits are waiting for you to play.
Since the trial operation last year, the Shuxi Lake Pavilion of Hefei Science and Technology Museum has successively "launched" many popular science exhibitions. In addition to the fire tornado, popular science exhibitions such as high-altitude bicycles, balance juggling robots, and outdoor water world are also gradually opening.
Do you dare to ride a bike on a thin rope high in the sky? Don't be afraid! Borrowing scientific knowledge, you don't have to be an acrobat to do it! The newly "new" high-altitude bicycle exhibition allows the experiencer to ride smoothly through the 33-meter-long steel wire through an ingenious device that shifts the center of gravity. The high-altitude bike is currently being tested and will continue to be available in the future.
On the third floor of the museum, there is also a "new friend" - the country's first balanced ball juggling robot to enter the science and technology museum. The robot looks square, but it is very flexible, and the user can put the ping pong ball from the pitching port, and the robot can start to juggle the ball skillfully.
Don't think that's all, the experiencer can control the robot to change the trajectory of the juggling ball, adjust the speed of the juggling ball, etc., by clicking on the touch screen, and the robot can also stop the ball with one key and collect the ball instantly.
The outdoor water world exhibit on the second floor of the museum area is also very eye-catching, which occupies an area about 8 times that of the Huangshan Road museum area, and will open this year. Through more than 30 groups of interactive exhibits such as water and fire fountains, water wheels, vortexes, fog cannon rainbows, and ship locks in the water world, children can learn about the magic of water in an interactive experience.
