morning news reporter Li Qin Photo Report
from the 26 floor to the 1 floor, how does it feel to sit on the slide? There is a special slide in the 88 Jin Ting District of Changning in Changning branch road. However, it is not an ordinary slide. It is a "escape slide" specially designed for escape from high-rise buildings. Yesterday, reporters learned the scene from the 26 floor winding down the "escape slide".
reporter experience
gliding state is a bit like skidding slide
this "escape slide" is set along the fire passage, about 50 centimeters wide, mainly composed of two parts: bend and straight grooves connected by the bend. The curved grooves are suspended in the air when they are not used at ordinary times, and the straight rows are hung on the wall when they are not used, which will not affect the normal use of the fire passage.
is a 7 - ten - day inventor, Zhou Miaorong, pointing to a device at the staircase, telling a reporter that, as long as the device is pulled and the plate effect, all the curved grooves will automatically drop into a straight line. Sure enough, his voice just dropped, and the curved slot came down. "Now the noise is a bit big, so we can only reduce noise by adding buffers."
the reporter then sat in the slots, "feet up, hands crossed on the chest, the body relaxed" - under the guidance of the staff, the journalist tried to adjust the posture to the best state and slide down. In the process of decline, every curve can feel the speed eased, but always in the natural sliding state, rather a bit of a slide. If people are relaxed and lie flat, the speed of sliding is the fastest; if you feel nervous, a little contact with the surface of the slot with the feet will slow down the decline. After
smoothly arrived at the first floor, except for too many turns, the reporter was a little dizzy, and there was no discomfort.
"the current design speed is 3-5 seconds per layer. If it is calculated at the fastest rate of 3 seconds / layers, it takes only 90 seconds from the height of 30 stories to the ground floor, and the residence of the 26 - floor high of King 88 may be shorter." Zhou Miaorong said so.
design concept
simple and practical, lying down can escape
How did Zhou Miaorong think of inventing the "escape slide"? He told reporters that he lived in the 35 floor, there were old and small in the family, so he paid special attention to high-rise buildings to save themselves. When there are accidents such as fire, there are three ways from high buildings to the ground: elevators, staircases and outer space. In case of fire, the elevator can not be used, and the risk of escape from outer space is too great.
"more than 90% of the people will choose to escape stairs, but there are many stairs and staircases, and there will be too many conditions, even stampede accidents." Zhou Miaorong believes that the staircase escapes the building high, the smoke and the choking, the water more slip, the people crowded and so on risk, and the main contradiction is "stand to escape", then can not "lie to escape"?
he changed his mind suddenly, and spent more than half a year in deep investigation and research. Zhou Miaorong invented this high-rise "escape slide". At present, Zhou Miaorong's invention has won the national patent, and has also been confirmed by the international patent PCT, and has been accepted or authorized by the United States, Japan, Brazil, Russia, Singapore, the United Arab Emirates and other countries. Will
momentum cause people to fly out of the escape slide?
Zhou Miaorong: the slope ensures that the escapees will not be thrown out of the grooves, and the slope will continue to glide through the curve. The combination design allows the escapees to keep the "fast slow fast" rhythm when they slide, and do not cause danger because of the speed. When
fire occurs in high-rise buildings, many devices may not be used properly, such as lighting. How can we ensure the safety of slides in a dark and busy environment?
Zhou Miaorong told reporters that the original "escape slide" did not take into account the situation, so there are defects in the design. But after the improvement, the "escape slide" has a set of special emergency lighting system and spray system. Once a fire occurs, the two systems will start at the same time when the switch is pressed. The bright escape environment will give people a sense of security, and the spray system can make people cover their nose and mouth with cloth soaked, and also enhance the safety factor of fire.
"from the 26 floor to the 1 floor, a lot of people will feel impulsive. Will it be dangerous to stop or people to fly out?" The reporter asked.
Zhou Miaorong told reporters: "in fact, there is no need to worry."
Zhou Miaorong's "escape slide" when designing, the groove, slope and curvature of curved grooves are very particular. The slope is 25 degrees. When turning, it can ensure that the escapees will not be thrown out of the grooves and the acceleration generated by the sliding of the straight groove. The slope is 45 degrees, so that it continues to slide through the curve; the width of 55 to 60 centimeters corresponds to the corner of 180 degrees, ensuring that the escapees in the corners slow down to almost 0. Such a combination design allows the escapees to keep the "fast slow fast" rhythm when they slide, and will not be dangerous because of the speed.
the ground floor of the first floor is parallel to the ground, but there is an upward angle between the straight and the straight groove, which can be used as the final buffer. The staff can easily stand upright from the chute through the armrest built on both sides.
"of course, if we really want to ensure safety, we must go through repeated practical exercises." Zhou Miaorong said so. When does
escape slide come into operation?
Zhou Miaorong: the largest one is to be approved by the relevant national quality department at present; without standard, it can not complete the product certification and the real promotion and use, can only be an innovative product that stops in the experimental stage; and we hope that the relevant departments can help one in a timely manner.
for Zhou Miaorong, what we most want now is to enable our invention to benefit more people living at the top. But even with the support of relevant departments, he found the first residential district to eat crabs in Changning District, and the second, third districts still do not know where they are. It is also not known when the escape slide can really play its role.
according to Zhou Miaorong's estimate, the cost of the escape slide is about 40 thousand yuan per floor, and the 30 floor is about 1 million 200 thousand yuan. Compared with the world's millions of dollars of escape capsule equipment, the price advantage is very obvious.
compared to the "cost" of this issue, Zhou Miaorong believes that the current biggest barrier is to be approved by the relevant national quality departments, only this step is passed, and then it is possible to promote more communities. But because the high rise "escape slide" is a new thing, the relevant national standards can not follow the standard, no standard will not be able to complete the product certification, the product can not be authenticated and no way to truly promote the use of the product can only be stopped in the experimental stage of innovative products. Therefore, in addition to reflecting the situation in many channels and waiting for relevant departments to handle, Zhou Miaorong can not do more. "
" there is an old saying that the whole society is advocating innovation. It is an innovation from scratch, and we hope that the relevant departments can help one in a timely manner. " Zhou Miaorong looks forward to the future of escape slides.
