High-rise building fire with self-descending escape device

Abstract

The invention relates to a high-rise building fire joint self-falling type escape device. The device is arranged on an outer wall of a public channel or a resident toilet in a building and is not prone to generating a fire area, the device comprises two main gear sets and a plurality of auxiliary gear sets, a cabin body and an annular gear belt, wherein the cabin body and the annular gear belt areperpendicular to each other and are of a one-to-one structure, the gear belt is meshed with each gear set, so that the serial-connected escape cabin can run on each gear set in a circulating mode, and an escape door and an escape port are arranged on the wall body in the public channel or the residential house, so that an escape person can open the escape door to enter the cabin body, the escapecabin can automatically run downwards after being loaded, the escape person is conveyed to the ground, electric power driving is not needed, and can also enable the one-way escape compartment to be reversely operated under the control of rescue personnel, and the fireman is conveyed to a destination floor for rescue and fire extinguishing. The device is beneficial to self-service evacuation of allpersonnel in a high-rise building and rescue fire extinguishing of firefighters, the device is high in conveying speed, safe and efficient, so that the life safety of people in a fire building is guaranteed.

Description

technical field [0001] The present application relates to the related technical field of escape equipment, in particular to a high-rise building fire-connected self-descending escape device. Background technique [0002] With the rapid development of social economy and the continuous growth of urban population, the places for people to live, live and work are becoming narrower and narrower. High-rise buildings have the advantages of less land occupation, high volume ratio, beautiful and compact, and are the first choice for urban development and construction. Therefore, the number is increasing, the floors are built higher and higher, showing diversified and comprehensive functions, and has become an important carrier of modern urban construction combination and urban image display. However, in high-rise buildings, a large number of people and materials are concentrated, and various lines and pipelines are criss-crossed, which is easy to cause fire. When a fire breaks out,...

AI Technical Summary

Problems solved by technology

[0005] (1) Open refuge floor: located on the top floor of the building or on the flat roof, there is no enclosure around it, the structure is simple, the protection ability is poor, and it cannot guarantee that it will not be invaded by smoke, and it cannot block wind, sand, rain and snow. It is only suitable for In warm areas, it is difficult for all people in the building to rescue themselves, get rescued and get out of the fire scene

[0006] (2) Semi-open refuge floor: there is a protective wall with a height of not less than 1.2m around it, windows and fixed metal shutters are set up on the upper part, which can prevent the intrusion of smoke, have good ventilation conditions, and can carry out natural smoke exhaust , but not suitable for cold areas, people cannot evacuate the fire

However, a power outage during a fire will lead to the paralysis of air conditioning and smoke control systems, and people will not be able to evacuate the fire-affected building

[0008] 2. The current escape devices are roughly divided into slow-down ropes, downhill pipes, elevators, gliding aircraft, etc., which are not suitable for young children, pregnant women, the elderly and the disabled.

It is difficult for the people in the building to achieve the goal of self-rescue, rescue, and rapid evacuation from the fire scene

[0009] 3. The elevator commonly used in Japanese residential buildings is to set the entrance directly to the ground on the floor of each floor, and the escapees will drill into it and descend downward. This kind of facility is not suitable for installation in high-rise and extremely high-rise buildings, and their physical fitness is poor. difficult to control

[0010] 4. The latest escape slide invented by a British designer is a long cylindrical device made of flexible fireproof material. Escapers enter the flexible cylindrical slide from the special entrances set on each floor. The speed reduction is different, it is easy to cause people to squeeze in the pipeline, and it is not suitable for pregnant women, infants, elderly, infirm and disabled people, and it does not have universal applicable functions.

It is not easy to equip all kinds of descending ropes, gliding pipes, elevators, gliding aircraft, parachutes and other equipment; even if equipped, they may not be sufficient, and it is even more difficult to operate, which is not suitable for all survivors

The above measures have many defects and cannot guarantee the rapid and safe evacuation of all personnel
