3. According to the invention, by designing the spiral blade, when the rotating shaft drives the damping rotating assembly to rotate, the damping liquid damps the liquid flow generated by the spiral blade to achieve the purpose of reducing the speed, no external power is required, and the structure is compact.
4. The invention utilizes the damping force of the damping liquid to replace frictional resistance to slow down the falling speed of a free falling body at a high position, the faster the speed in the falling process is, the faster the blade rotates, the greater the resistance of the damping liquid to the blade is, the rotating speed of the blade is reduced, the falling speed is reduced, the damping holes arranged on the blade can generate pressure when the damping liquid passes through the damping holes, so that the rotating speed of the blade is further reduced, and the falling speed is further reduced.
5. The invention can be effectively applied to high-rise rescue and escape, and has the advantages of simple operation, complete functions, convenient cascade, good use effect and convenient popularization and use.
In conclusion, the device disclosed by the invention is simple in structure, reasonable in design, convenient to implement, capable of being effectively applied to high-rise rescue and escape, simple to operate, convenient to cascade, good in using effect and convenient to popularize and use.
The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.
