Embodiment Construction

[0020] Below in conjunction with accompanying drawing and adopt conceptual empirical formula to describe in detail the technical scheme of invention:

[0021] Such as figure 1 As shown, the lifesaving equipment of the present invention includes, including a gas cylinder 8, a rotating propeller hub 2 and a rotor 1 connected to the rotating propeller hub 2, a chute is arranged on the lower end surface of the rotor wing 1, and a sliding groove is also arranged on the rotating propeller hub 2. Rail type support bar 3, slide rail type support bar 3 is arranged in the chute. The upper surface of the end of the rotor is provided with an exhaust hole 12, and the inside of the rotor is also provided with a closed rotor cavity 13 communicated with the exhaust hole 12. The rotating propeller hub has an airtight cavity. The side is provided with an air pipe connected to the closed rotor cavity 13, the gas cylinder 8 is connected to the closed rotor cavity 13 through the connecting pipe 7...

Abstract

The invention discloses rotary wing type high-rise life-saving equipment. The rotary wing type high-rise life-saving equipment comprises a rotating propeller hub and a rotating wing connected on the rotating propeller hub. The rotary wing type high-rise life-saving equipment is characterized in that exhaust holes are arranged in the upper end face of the end portion of the rotating wing, and a closed type rotating wing inner cavity communicated with the exhaust holes are further arranged inside the rotating wing. The rotating propeller hub is provided with a sealed cavity, a gas conveying pipe connected to the closed type rotating wing inner cavity is arranged on the side face of the cavity, the lower end of the cavity is connected with a connecting pipe through a bearing connection part, the lower end of the connecting pipe is connected with a gas cylinder, a valve is arranged on a gas outlet of the gas cylinder, and the gas cylinder is provided with a harness system. Compared with parachute type life-saving equipment and ladder rail type life-saving equipment in the prior art, the rotary wing type high-rise life-saving equipment has the outstanding advantages of being simple in structure, light in weight, small in size, easy to operate, free of power consumption and height loss and the like, capable of being used for high-rise life saving and activities such as flight entertainment and soldier air landing, and high in reliability.

Description

technical field [0001] The invention relates to a life-saving device for a high-rise building which is driven by a gas source of a gas cylinder to move a rotor and decelerates and descends through aerodynamic force, and solves the problems of complicated and poor practical operability of the current high-rise life-saving equipment. 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 ...
