The specific embodiment
Below in conjunction with accompanying drawing and adopt conceptual empirical equation to the 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 that rotates on propeller hub 2, is provided with chute in the lower surface of rotor 1, rotate on propeller hub 2 and also be 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, also be provided with the closed rotor inner chamber 13 that is communicated with this steam vent 12 in the inside of rotor, rotate propeller hub and have an airtight cavity, be provided with the appendix that is connected to closed rotor inner chamber 13 in the side of cavity, gas cylinder 8 is connected with closed rotor inner chamber 13 by tube connector 7, be provided with valve 9 in the gas outlet of gas cylinder 8, be provided with harness system 10 at gas cylinder, harness system 10 is furnished with quick-detachable lock 11.
Lifesaving appliance of the present invention drives by gas jet the high-rise building life saving equipment that rotor 1 moves.Gas cylinder 8, tube connector 7 are contained in the rotor below by the 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, enter closed rotor inner chamber 13 by flexible pipe 4, several lateral row pores 12 discharges by rotor wing tip place produce horizontal impulse, drive rotor and rotate.Rotor produces certain lift in rotation process, reduce the human body decrease speed, reaches the purpose that safety is landed.
When the condition of a disaster occurs, this equipment is backed on the body by harness system, open adjustable valve, jump forward at balcony or window, jump out high building (personnel's skip distance forward is between 1.5 meters to 3.5 meters).In theory, the rotor length just can guarantee not collide with body of wall less than 1.5 meters.
The realization of one, safe landing speed
In the 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 when human body and rotor life-saving equipment, finally reach dynamic balance, descend with stabilized speed.During less than 7 m/s, the people is safe when settling landing speed.
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
Take human body-85 kilograms of the highest gross weights of rotor life-saving equipment assembly as example, this moment the adjustable valve standard-sized sheet, rotor rotates with maximal rate, will provide maximum lift for assembly.At this moment, the aerodynamic drag that the people-the equipment assembly descends safely is less than 158.8 newton, and rotor need provide 674 newton's aerodynamic lift just can satisfy the requirement of safe landing, and this moment, the rotary speed of rotor was per second 66.6 degree.
For the crowd of Different Weight, can pass through controlling opening of valve, thereby different jet flow flow and the speed of generation obtains the purpose that different rotary speeies realizes that safety descends.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 satisfy 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 the 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, before and after 6 liters of rotor air chamber total measurement (volume)s, puff prot, pressure dependence can cause spout to present supercritical flow state, calculates through theory, and a rotor area of injection orifice is 40mm
2Just can satisfy the thrust requirement, keep the approximately 3.8 seconds time of this constant thrust, the building height less than 26.6 meters is all satisfied safety requirements.After landing, valve-off is freed lock by braces 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 present employing, this device can have enough intensity rapidly away from dangerous building, and security also can effectively be guaranteed; Compare with the ejection parachute method of carrying, there is no the minimum altitude requirement of building, and rotating diameter is little, can not disturb with surrounding environment generation hooking as parachute; 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.
