Slow descent method for high-altitude escape and high-altitude escape device

Abstract

The invention discloses a slow descent method for high-altitude escape and a high-altitude escape device using the slow descent method. The method utilizes a reverse damping torque generated when a rotor impeller and a stator impeller rotate at a high speed relatively in oil liquid to suppress the rotating speed of the rotor impeller, the device mainly comprises a descent control device, a life-saving rope and a fixing device, wherein the descent control device comprises the stator impeller, the rotor impeller, a shell and a shaft, the stator impeller and the rotor impeller are of two disc structures which are oppositely placed and capable of rotating relative to each other and having front inclined blades on two opposite surfaces respectively, the stator impeller and the shell are fixedly and hermetically connected to form a sealed space filled with oil, the rotor impeller is placed in the sealed space and can rotate relative to the stator impeller and the shell through the shaft, one end of the life-saving rope is connected to the shaft, and the other end thereof is connected with a user or life-saving equipment. The slow descent method disclosed by the invention is safe and reliable, and the high-altitude escape device disclosed by the invention is simple in structure, safe and firm, convenient to operate and wide in application range.

Description

technical field [0001] The invention relates to the field of high-altitude emergency escape, in particular to a slow-down method for high-altitude escape and a high-altitude escape device using the method. Background technique [0002] At present, there are more and more high-rise and super-high-rise buildings in cities. Once disasters such as fires and earthquakes occur, and people are trapped in the house by the fire and cannot escape, they can only wait for firefighters to come to the rescue. People's life safety has been greatly threatened. For the above problems, people have developed many escape methods and escape tools. There are many high-altitude escape devices in the prior art, but there are the following problems: 1. Complex structure, heavy volume, high manufacturing cost, Difficult to be popularized and applied; 2. Difficult to operate, and it is difficult for trapped persons to operate in emergency situations such as disasters; 3. Does not have automatic return...

[0002] At present, there are more and more high-rise and super-high-rise buildings in cities. Once disasters such as fires and earthquakes occur, and people are trapped in the house by the fire and cannot escape, they can only wait for firefighters to come to the rescue. People's life safety has been greatly threatened. For the above problems, people have developed many escape methods and escape tools. There are many high-altitude escape devices in the prior art, but there are the following problems: 1. Complex structure, heavy volume, high manufacturing cost, Difficult to be popularized and applied; 2. Difficult to operate, and it is difficult for trapped persons to operate in emergency situations such as disasters; 3. Does not have automatic return function, even if it has return function, it needs to be operated by trapped persons at high places to return High, unable to adapt to the use when many people need to escape; 4. The installation is complicated, and the structural requirements for the use site are relatively high
