Anti-collision rotor wing type high-rise life saving equipment and damper used by same

Abstract

The invention discloses anti-collision rotor wing type high-rise life saving equipment and a damper used by the same. The life saving equipment comprises a propeller hub, variable pitch blades, an annular automatic incliner, the damper and a gas cylinder, wherein exhaust holes are laterally formed in the tips of the variable pitch blades; closed blade inner cavities communicated with the exhaust holes are formed in the variable pitch blades; the propeller hub is connected with a closed cavity through a waving hinge; the annular automatic incliner is fixed out of the cavity; a gas transmission pipe connected to the closed blade inner cavities is arranged on the side surface of the cavity; the lower end of the cavity is connected with a connecting pipe through a thrust bearing connecting piece; the lower end of the connecting pipe is connected with the gas cylinder; a valve is arranged in a gas outlet of the gas cylinder; a harness system is arranged on the gas cylinder; and the damper is connected with the annular automatic incliner and the outer wall of the connecting pipe. Compared with traditional rotor wing type high-rise life saving equipment, the anti-collision rotor wing type high-rise life saving equipment has the characteristics of collision prevention and high adaptability.

Description

technical field [0001] The invention relates to an anti-collision rotor type high-rise life-saving equipment, in particular to an anti-collision rotor type high-rise life-saving equipment and a damper used therefor. Background technique [0002] With the rapid development of modern society, there are more and more high-rise buildings. However, in case of emergency situations such as fires and earthquakes, it is difficult for people who work and live on high-rise buildings to escape. Existing high-rise life-saving equipment mainly contains two life-saving modes of relying on the building exterior wall and rapidly away from the building. Relying on the external wall, there are several forms such as rope type, chain ladder type, and bag type. They all need to rely on buildings to escape by sliding down and climbing. However, these devices are easy to spread the flame upwards, and the strength is difficult to guarantee. Security is compromised and it cannot really be used in pr...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a safe, reliable and easy-to-operate anti-collision rotor-type high-rise life-saving equipment and the damper used to achieve deceleration through aerodynamic force, which solves the design defects of the existing rotor-type high-rise life-saving equipment. It can automatically stay away from the building during use. When the person keeps a safe distance from the building, under the action of aerodynamic force and damper, the paddle disc will automatically level up, so that the rescued person can only descend in the vertical direction.
