The specific embodiment
Below in conjunction with accompanying drawing and adopt conceptual empirical equation to invention technical scheme be elaborated:
As shown in Figure 1, lifesaving appliance of the present invention comprises, comprises gas cylinder 8, rotates propeller hub 2 and be connected to the rotor 1 rotating on propeller hub 2, in the lower surface of rotor 1, is provided with chute, rotate on propeller hub 2 and be also provided with slide rail type support bar 3, slide rail type support bar 3 is arranged in chute.Upper surface, end at rotor is provided with steam vent 12, in the inside of rotor, be also provided with the closed rotor inner chamber 13 being communicated with this steam vent 12, rotate propeller hub and there is an airtight cavity, in the side of cavity, be provided with the appendix that is connected to closed rotor inner chamber 13, gas cylinder 8 is connected with closed rotor inner chamber 13 by tube connector 7, in the gas outlet of gas cylinder 8, be provided with valve 9, at gas cylinder, be provided with harness system 10, harness system 10 is furnished with quick-detachable lock 11.
Lifesaving appliance of the present invention, the high-rise building life saving equipment that drives rotor 1 to move by gas jet.Gas cylinder 8, tube connector 7 are contained in rotor below by bearing connector, wherein gas cylinder 8 is gas cylinder, after valve 9 is opened, the air-flow of gas cylinder enters and rotates propeller hub 2, by flexible pipe 4, enter closed rotor inner chamber 13, several lateral row pores 12 by rotor wing tip place are discharged, and produce horizontal impulse, drive rotor to rotate.Rotor, in rotation process, produces certain lift, reduces human body decrease speed, reaches the object that safety is landed.
When there is the condition of a disaster, this equipment is backed on the body by harness system, open adjustable valve, at balcony or window, jump forward, jump out high building (personnel's skip distance is forward between 1.5 meters to 3.5 meters).In theory, rotor length is less than 1.5 meters and just can guarantees not collide with body of wall.
The realization of one, safe landing speed
When human body and rotor life-saving equipment are in decline process, be subject to the acting in conjunction of the aerodynamic drag that aerodynamic lift, human body and lifesaving appliance assembly that gravity, rotor produces produce, finally reach dynamic balance, with stabilized speed, decline.When settling landing speed is less than 7 m/s, people is safe.
The length of setting the chord length of the wing is 0.1m * 1.2m, and the projected area of human body-rotor equipment is 4.5m
2, the lift coefficient of rotor is set as 2.2, and the resistance coefficient of people-life-saving equipment assembly is set as 1.2, and atmospheric density is 1.2kg/m
3.
85 kilograms of the highest gross weights of human body-rotor life-saving equipment assembly of take are example, adjustable valve standard-sized sheet now, and rotor rotates with maximal rate, will provide maximum lift for assembly.Now, the aerodynamic drag that people-equipment assembly declines is safely less than 158.8 newton, and rotor need provide 674 newton's aerodynamic lift just can meet the requirement of safe landing, and now the rotary speed of rotor is 66.6 degree per second.
For the crowd of Different Weight, can pass through controlling opening of valve, thereby produce different jet flow flows and speed, obtain different rotary speeies and realize the object that safety declines.For special weight crowd, this life-saving equipment is also with counterweight sandbag and air bag type buffering shoe cover, and the lighter adds and ties up sandbag, and severe one is put on air bag buffering shoe cover, just can meet Different Weight personnel's safe landing requirement.
Two, the realization of rotor wing rotation speed
According to Fig. 1, exhaust outlet ejection γ-ray emission horizontal thrust, and produce turning moment, rotor is rotated.In rotation process, can be subject to the effect of rotor aerodynamic drag moment, gas jet damping torque and transmission mechanism resistance torque.Work as equalising torque, rotor wing rotation speed reaches stable.
The resistance coefficient of setting rotor is 0.05, and drag overall torque setting is 10 Ns of rice, and spout to the distance of spindle central is 1 meter.With the corresponding maximum (top) speed analysis of maximum weight, a rotor spout need provide 12 newton's thrusts.
If the pressure of environment and gas cylinder is respectively 1atm and 15atm; 4 liters of gas cylinder volumes, 6 liters of rotor air chamber total measurement (volume)s, before and after puff prot, pressure dependence can cause spout to present supercritical flow state, through theory, calculates, and a rotor area of injection orifice is 40mm
2just can meet thrust requirement, maintain the approximately 3.8 seconds time of this constant thrust, to being less than the building height of 26.6 meters, all meet safety requirements.After landing, valve-off, by braces solution lock-off, lifesaving appliance is separated.If depth of building changes, can match different gas cylinder volumes, the requirement of pressure assurance high-rise building life saving.
Compare with the exterior wall supported type method of carrying of current employing, this device can have enough intensity rapidly away from dangerous building, and security also can effectively be guaranteed; Compare with ejection parachute method of carrying, there is no the minimum altitude requirement of building, and rotating diameter is little, can as parachute, not disturb with surrounding environment generation hooking; Compare with current rotor craft (as helicopter, gyroplane), simple in structure, easy to operate, energy free consumption.It is little that patent of the present invention also has floor space, easy donning carrying, the advantage that reliability is high.
