It only takes about 3 minutes to escape from a 100-meter high-rise fire, and you can escape without "sitting" on the stairs

Technicians demonstrate the use of "Escape Fast" and folding seats

In high-rise buildings, in the event of a fire, the use of the fire escape in the stairwell is the main way to escape. But when the danger really comes, the residents are evacuated from the stairwell, and the chaos is disorderly, coupled with the smoke and obstructed vision, it is easy to cause stampede accidents. In particular, vulnerable groups such as the elderly, the weak, women and children are slow to move and it is difficult to evacuate. Many people can only wait for rescue, unable to effectively save themselves and each other.

In order to effectively solve the worldwide problem of group emergency evacuation of high-rise building personnel, a company in Xi'an has created a "high-rise building emergency support system" through independent research and development and technological innovation, transforming the traditional staircase handrail into a "level-emergency dual-purpose" handrail track, with the core device "escape fast" and folding seats, to realize the rapid evacuation of high-rise personnel in danger in an emergency, and innovatively put forward a three-dimensional prevention, control and rescue system of "prevention, elimination, rescue" + "escape".

In 2019, "Xi'an Evening News" once reported that the fire "escape artifact" of Shaanxi Xianrun Industrial Development Co., Ltd. exploded on the Internet with the title of "Fire "Escape Artifact" Unveiled in Fengxi New Town". Because of its creativity, ingenious design and practical products, it has been hotly discussed by netizens. In the past 5 years, taking advantage of the "east wind" of Qin Chuangyuan and Xi'an's "double center" construction, what is the application scenario of this "eye-catching" product, and are there any new achievements? The reporter conducted an in-depth investigation.

The product is upgraded in an all-round way

The traditional "walking escape" has become a "mechanical escape"

"After several years of market-oriented application and research, at present, our products have been upgraded in an all-round way in terms of appearance, material, and performance." Knowing the reporter's intention, Cui Man, deputy general manager of Shaanxi Xianrun Industrial Development Co., Ltd., took the reporter to Tianfu Heyuan Community in Fengxi New Town. The community has completed the renovation of the "high-rise building emergency support system" project in the stairwell fire escape.

Wear the seat equipment, hang up the core device, start, slide, turn smoothly, and stop when you brake...... At the same time as the on-site demonstration of the technicians, Cui Man introduced that the upgraded physical device of the system is still composed of three parts: the handrail track, the core patent "escape fast", and the folding seat.

The reporter saw that there was no obvious difference between the modified stairwell handrail track and the ordinary staircase handrail, but there was a groove in the lower part of the handrail. "On the premise of not changing the original structure of the building, we renovated the staircase handrail to make it have the dual functions of handrails and escape. The first generation of products uses stainless steel round pipes, but it is easy to stall when exposed to water and oil stains, and the friction increases when encountering dust, which affects the sliding efficiency. Now the high-strength aluminum alloy special-shaped track is used, and the load on one side can reach more than 600 kg. ”

The core patented product "Escape Fast" is the key device of the system. It used to weigh 4 catties, but now it weighs 3 catties, which is more convenient for vulnerable groups; It used to bear 100 kg, but now it can bear more than 150 kg; The internal use of high-strength new materials, the use of pure mechanical design principles, with the self-developed "uniform speed slow descent" speed limiting technology, no matter how heavy the person uses, can not be affected by water, dust, combustion residues, etc., overcome the gravitational acceleration, with a comfortable speed of 0.8-1.2 m/s to go down at a uniform speed; In the past, the braking effect was not obvious, and now the wear-resistant, high-temperature-resistant, and anti-aging rubber brake pads are used to increase friction resistance. "The biggest highlight of this device after the upgrade is that it can be 'blind installation', in the past, it was inconvenient for the user to operate in the thick smoke state, but now it only needs to be stuffed in and turned around, so as to achieve one-second clamping and go at any time."

The folding seat is made of B1 fireproof material, which is used to "escape fast". Hook the rings on both sides of the seat to the "Escape Fast" hook to initiate the sliding in a seated position. Reflective material is also embedded in the back of the seat to ensure that those behind behind the smoke can clearly see the people descending in front of them and maintain a safe distance.

"Using our products, we can change the traditional 'walking escape' to 'mechanical escape', and transform 'passive rescue' and 'waiting for rescue' into 'active self-rescue and mutual rescue'. The 100-meter high-rise can be evacuated to the ground in about 3 minutes, which greatly saves the time for self-rescue. Cui Man said.

Multi-party linkage to "make the best use of things"

Ensuring that people in distress "escape quickly"

In the early stage of the fire, how to respond quickly, judge and dispose of it, and remind the residents of the whole building to evacuate quickly in the shortest time? According to Cui Man, on the basis of the "high-rise building emergency support system", they have created a "high-rise building emergency safety escape intelligent connection system (emergency alarm + intelligent connection management platform)."

In case of fire and other emergencies, residents can send a distress signal through the alarm installed at home or the mobile phone, and the Zhilian management platform will send the alarm information to all emergency contacts in the entire building or community, the property management platform and the 119 command center. Residents can quickly wear folding seats, use "escape fast", and complete self-rescue through the special handrail track in the stairwell, seize the golden time, and ensure life safety to the greatest extent.

The Zhilian management platform will collect and feedback information, comprehensively analyze data statistics, provide remote assistance for dynamic monitoring, track and handle the whole process of events, and provide firefighters with on-site conditions and accurate rescue information to improve rescue efficiency.

Shaanxi Provincial Technology Transfer Center's "Scientific and Technological Achievements Evaluation Report" commented on the system: "It has improved the self-rescue and mutual rescue ability and active self-rescue awareness of urban high-rise building personnel, solved the worldwide problem of emergency self-rescue and escape of high-rise building personnel, and filled the gap of fast, safe, efficient, convenient and autonomous escape equipment for vulnerable groups such as the elderly, weak, women and children in emergencies such as high-rise building fires, and is the original innovation, breakthrough practice and popular application in the field of high-rise building safety escape. It has high social value and practical significance. ”

At present, the intelligent connection system has been connected to the "City Brain" of Haidian District, Beijing, to achieve multi-party linkage, remote command, and information and data sharing.

"The stairwell of a high-rise building is not only a fire evacuation route, but also a life passage." Cui Man told reporters that they will "make the best use" of the modified handrail track, and also simultaneously developed the "patrol accurate" intelligent inspection robot. On weekdays, "accurate patrol" can replace manual work, independent "work", inspect and monitor the space environment of the fire passage, check whether the fire door is closed, whether there is debris stacked, etc., and transmit the data to the property management background to facilitate timely disposal and ensure the smooth passage of life.

Promote the application in many places

The "high-rise building emergency support system" has benefited more than 200,000 people

"There are also many fire escape products on the market, but most of them are out-of-building escapes, such as slow descenders, parachutes, etc., and there are many restricted factors." Cui Man said that from the "four nos" faced by the people involved in danger after the fire - no way to escape, nowhere to escape, disorderly escape, and no intention to escape, to the "four haves" - self-rescue awareness, self-rescue measures, self-rescue paths, and self-rescue facilities, their high-rise escape system is the only innovative technology in this field at home and abroad, which is the first of its kind.

At present, the company's "high-rise building emergency support system" has been applied in multiple scenarios in Xi'an, and has been promoted and implemented in Beijing, Guangdong, Zhejiang, Jiangsu, Shandong and other provinces (cities), covering resettlement communities, hospitals, nursing homes, schools, office buildings, industrial parks, etc., benefiting more than 200,000 people.

A total of 51 exclusive patents and 3 computer software copyrights have been applied; Recognized as "National High-tech Enterprise", "Science and Technology Small and Medium-sized Enterprise" and "Innovative Small and Medium-sized Enterprise"; Won the 4th "Safety Science and Technology Progress Award" of China Association of Work Safety, and was selected as the 2023 Capital Emergency Management Innovation Case and Shaanxi Science and Technology Innovation Excellent Case...... Technological innovation is the secret of the company's rapid growth.

In addition to having its own R&D team, the company has also established cooperation with universities and institutes such as the University of Emergency Management and China Northwest Architecture Design and Research Institute Co., Ltd. to carry out collaborative research in production, education, research and application, and form a comprehensive high-rise building emergency guarantee solution of "product + technical service".

According to Cui Man, recently, their latest research and development achievement "automatic fire extinguishing robot" has been landed, the robot is suitable for museums, libraries, warehouses, factories and mines, tunnels and other public places, to achieve automatic inspection of routine status, AI analysis of special scenes, intelligent identification and fire extinguishing.

"Fengxi New Town, Xixian New Area, has given great help to enterprises in terms of talent introduction, scientific and technological research and development, and financial support. With the acceleration of the construction of Qin Chuangyuan and Xi'an's 'double centers', the relevant industrial chains have gathered rapidly, alleviating the problems of upstream raw materials and downstream channels of enterprises. Cui Man said that at present, Xi'an is accelerating the construction of "double centers" in the formation of momentum, urban governance efficiency in wisdom and resilience, prevention and resolution of major risks to achieve new breakthroughs in the level of ability, greatly boosting the confidence of enterprise development. In the future, they will continue to strengthen technological innovation, promote the application of more new technologies and new products in more scenarios, and provide more reliable protection for the safety of people's lives.
