為什么天安門廣場LED紅燈籠風都吹不動?背后滿滿黑科技!
 
對于我們中國人來說,在遇到一些喜事的時候,都會在自己的門前掛上大紅燈籠來表示慶祝,LED紅燈籠,不僅會讓場景看上去更加的喜慶,而且也是我們的一種民族文化。在祖國70周年華誕之際,天安門廣場上也高高懸掛起了大紅燈籠,覺得難以理解的是,這些紅燈籠在風中紋絲不動,根本不會像平常的燈籠那樣隨隨便便地被風刮掉,那么這些燈籠為什么會這樣呢?卓格光電帶大家來看一下吧。
 
這些LED燈籠的直徑5米,高4.2米,如此龐大的體積之所以可以一動不動,是因為大型燈籠的技術標準完全采用了航天標準,與此同時用來支撐燈籠的繩子采用的是方綸繩,是衛星飛船回收時所用的材料,雖然只有6毫米粗,但是卻能夠承受800公斤的力量,這樣的繩子就已經確保了燈籠的絕對安全,而且在放置燈籠的時候,也要綜合運用空氣動力學和理論力學等領域的專業知識,這樣才能夠確保燈籠紋絲不動的高懸在天安門廣場上。
 
不得不說,今年的國慶閱兵真的是讓人覺得非常的欣喜,不僅向人們展示了我國的軍事實力,更是讓人們看到了我國對于環境保護的決心,更讓我們看到了我們新愿意的科技發展,也看到了人民無盡的想象力與創造力,而這些滿滿的黑科技的背后是所有人的辛苦付出,正是因為有我們的存在,所以祖國才能夠變得越來越好!
 

Why is the red lantern in the square square still unable to move? Behind it is full of black technology!
 
 
For our Chinese people, when we meet some happy events, we will hang red lanterns on their own doors to celebrate. The red lanterns will not only make the scene look more joyful, but also our national culture. On the occasion of the 70th anniversary birthday of the motherland, red lanterns were also hung up high in the square. It is hard to understand that these red lanterns remain motionless in the wind and will not be swept away by the wind as ordinary lanterns. Why are these lanterns so? Xiaobian thinks you can have a look.
 
 
These lanterns are 5 metres in diameter and 4.2 metres in height. The reason why such a huge volume can not move is that the technical standard of large lanterns completely adopts the space standard. At the same time, the rope used to support the lanterns is made of square fibre rope, which is the material used for the recovery of satellite spacecraft. Although only 6 millimetres thick, it can withstand 800 kilograms of force, so the rope is able to withstand 800 kilograms of force. The safety of lanterns has been ensured, and the expertise in the fields of aerodynamics and theoretical mechanics should be integrated in order to ensure that lanterns are still on the Tiananmen square.
