Description

Knapsack formula slowly falls escape device

Technical Field

The utility model belongs to a fire safety equipment especially relates to a knapsack formula escape device that slowly falls.

Background

When disasters such as earthquake, fire and the like occur, the high-rise building is difficult to escape due to the structural characteristics of the high-rise building and a plurality of people, and is also a major problem of social public safety. When fireworks, toxic gas or other disasters occur in a high-rise building, particularly when the disasters cannot be controlled rapidly, the people living, studying and working in the building can utilize evacuation equipment to escape emergently. In fire-fighting regulations, general elevators for passenger are required to be stopped for safety and reliability in terms of smoke prevention, power failure, mechanical failure and the like; the walking stairs become the main facility for evacuating people in high-rise buildings. But the evacuation route of the walking stairs is long, the time consumption is large, and the efficiency is low; and the fire fighting equipment in the channel and the staircase is often lost, damaged and out of the proper position or state, the fire and fire or obstacles often damage and block the escapers during the outbreak of the fire, and the high-rise people are more difficult to evacuate safely.

The escape method from exits such as balconies, windows and the like is adopted, so that the escape method can be separated from the attack of fire and smoke in the building. The sliding descent method of making human body fall slowly by using auxiliary equipment can ensure safe escape and pay attention to speed, and the escape mode can be called slow descent escape. The existing slow-descent escape products mainly comprise slow-descent ropes, gliding pipelines, elevators, gliding aircrafts and the like. Compared with other escape products, the slow descending rope has the advantages of simple structure, easiness in operation, low cost and the like.

The conventional descent control device in the prior art comprises a speed regulator, a safety belt, a safety hook, a steel wire rope and the like. The user hangs the couple earlier on the object that can the bearing such as indoor window, pipeline, then with bandage system at human waist, slowly descend to ground from the window, its descent speed is about 0.5 ~ 1.5 meters per second. The descent control device is too simple in structure, the body is fixed only by the binding band on the waist, the requirement on physical performance of a user is high, soft tissue contusion is easy to occur at the tightened part of the binding band, and safety is poor.

Publication No. CN 207970352U's utility model discloses a high-rise knapsack of fleing for fire, flee and slowly fall the ware including knapsack body and high-rise, the knapsack body includes knapsack main part and knapsack safety belt, the knapsack safety belt connect in the knapsack main part, the knapsack main part has slowly falls the ware and places the district and be used for setting up the first district of placing of firebreak device, high-rise escape slowly fall the ware set up in slowly fall the ware and place the district. The backpack descent control device has certain safety improved relative to a bandage type descent control device, but because the suspension point of the descent control device is positioned inside a building or on a wall surface, a human body is very easy to collide or rub with the wall surface under the action of rope tension, natural wind power or other external forces in the descending process, and the backpack descent control device is easy to cause personal injury in the actual use process because of no corresponding protection measures, so that the backpack descent control device is very necessary to protect important parts.
