Description

High-altitude descent control device for emergency escape

Technical Field

The invention relates to the technical field of fire safety, in particular to a high-altitude descent control device for emergency escape.

Background

With the increase of the height of buildings, escape and rescue in dangerous situations are becoming increasingly difficult. Many homes and businesses have therefore installed high altitude descent control devices. The existing descent control device realizes uniform-speed descent through friction between a centrifugal block arranged on a rotating wheel and a side wall.

In the working process of the existing descent control device, the gravity of a human body drives the rotating wheel to rotate, so that centrifugal force is generated to enable the centrifugal block to rub against the side wall to generate frictional resistance, and the centrifugal block and the gravity are balanced. On one hand, the centrifugal force is positively correlated with the speed and the mass of the centrifugal block, and because the centrifugal block has a large difference with the mass of the human body, a speed reducing mechanism is usually required to be arranged between the centrifugal block and the rotating wheel to increase the rotating speed of the centrifugal block and reduce the speed of the rotating wheel, so that the reliability of the whole structure is low, particularly, the high-temperature deformation caused by fire and long-term unused rusty sundries can cause the speed reducing mechanism to be stuck or the centrifugal block to be stuck, so that the descent control device is not stopped or stalled, on the other hand, the larger the gravity of a person is, the larger the friction force is, the larger the rotating speed of the rotating wheel is, the descending speed of an adult with fat weight is far greater than the descending speed of a small juvenile person during escape, a lighter person can descend too slowly or be stuck, and a fat person can be injured due to.

Furthermore, the existing buffers are often used in a queue only one by one during escape, thereby wasting a great amount of valuable escape time, and more seriously, possibly causing moral crisis.
