High-altitude self-rescue device

Abstract

The invention discloses a high-altitude self-rescue device which mainly comprises a hollow spherical air bag and inflation equipment, wherein the air bag consists of an outer casing and an inner casing; the outer casing is connected with the inner casing by a connecting rope to form a sealed inflation space; zippers capable of being opened from the outside and the inside are arranged in same positions of the outer casing and the inner casing. After a person enters, the inner and outer zippers are zipped and then an explosive inflation barrel is started for inflation, so that the person is surrounded by an inflated spherical space, and protected against a severe injury when falling from a high altitude.

Description

technical field [0001] The invention relates to a high-altitude self-rescue device for jumping from a high place, which belongs to high-altitude escape technology. Background technique [0002] When people are in a dangerous situation at a higher position and need to escape, such as a high-rise building, they often have to take a risk and escape downward, or escape upward to a higher position to wait for rescue. In addition, escape can also be achieved through ladders, ropes or even helicopters. Escape by helicopter is usually unrealistic. One is that the cost of rescue is too high, and the other is that it is limited by the rescue environment and the number of people who can be rescued each time is small. If adopting the way of aerial ladder to rescue, there are following disadvantages: first, the height of aerial ladder is limited, the existing buildings are often more than 100 meters, and the height of aerial ladder cannot rise to higher floors; second, the traffic capac...

Problems solved by technology

It is usually unrealistic to escape by helicopter. First, the cost of rescue is too high. Second, it is limited by the rescue environment and the number of people who can be rescued each time is small.

If adopting the way of aerial ladder to rescue, there are following disadvantages: first, the height of aerial ladder is limited, the existing buildings are often more than 100 meters, and the height of aerial ladder cannot rise to higher floors; second, the traffic capacity of aerial ladder is limited, and the rescue speed is relatively slow , thirdly, it will be restricted by erection and access to the site, and fourthly, the reaction speed is slow, and the site cannot be reached in time

The simplest and most practical way is to use a rope to escape, but this method has the following disadvantages: one is that the rope is difficult to fix, and the other is that the climbing process is relatively difficult. Usually people have not received similar professional training in climbing, and they are easy to fall. Next, the third is that when the flames of the fire leap out of the building, they may also burn the rope or burn the escape personnel.

[0003] Therefore, although people are trapped in many cases, they can only choose to passively wait for rescue.
