Abstract

The utility model relates to a safety air landing device, making use of aerovane circumgyration to generate lifting force to realize safe landing; the utility model comprises a plurality of retractable disc aerovanes, a central wind wheel, a bearing pedestal, a connecting rod, a handle and a safety belt. When air landing begins, back draught can drive the central wind wheel to rotate at a high speed and make the disc aerovanes which are evenly distributed fixed on the central wind wheel to rotate synchronically; the lifting force generated by rotation can control the falling speed of air landing objects within safety range to realizing safe landing.

Description

Safe Airlanding device

Affiliated technical field

The utility model relates to aerial unpowered safe Airlanding device.

Background technology

At present, known aerial unpowered safe falling device is a parachute, and it is made up of cloth matter canopy and umbrella rope, and the air resistance that relies on canopy to open generation aloft slows down the heavy burden thing that is hung under the canopy and drops to ground with safety speed.But, parachute has a lot of technical limitation in practical operation, factors such as opening altitude, environment, wind speed all will directly influence the normal performance of its usefulness, owing to be the soft junction structure, and area is bigger, exist the forward and backward phase to prepare to require shortcoming easy to hang in height, the use, easy winding, thus the generation that brings some accidental injuring events.

Summary of the invention

In order to overcome the deficiency that parachute is subjected to all multifactor impacts, the utility model provides a kind of safe Airlanding device, and it can not only finish the usefulness of parachute, and it is little influenced by external factor, and is simple to operate, light small and exquisite.

The technical scheme that its technical matters that solves the utility model adopts is

Safe Airlanding device is the T-shape structure, is made up of multi-disc rotor, center wind wheel, bearing seat, pipe link, bracing frame, handle etc.It compares maximum different being of realizing same purpose with parachute---the parachute utilization be the resistance of air, safe Airlanding device utilization be that airborne body potential energy transforms and the rotor lift of generation.

Safe Airlanding device by the multi-disc rotor that can produce lift 1., by the wind wheel of wind-force rotation 2., the set collar that connects rotor and wind wheel 3., the center shaft bearing 4., pipe link 5., bracing frame 6., handle 7., 8. safety strap wait several parts to form.When producing the landing behavior, the potential energy of airborne body will be converted into the kinetic energy of airborne body tenesmus, airborne body and Airlanding device are aloft dropped, it is poor that air forms inverted speed relatively, under the effect of reverse air flow, the center wind wheel revolves fast and drives and is fixed on that the multi-disc rotor rotates synchronously on the wind wheel outer shroud, and the rotor of rotation just can produce certain lift.The lift that continues to produce is equivalent to the resistance that parachute produces, so Airlanding device can reach the purpose of safe falling as parachute.Because the two structure and principle is different, Airlanding device will effectively be eliminated many shortcomings that parachute exists when reaching same purpose.

The beneficial effects of the utility model are, can realize the purpose of safe falling, have eliminated the parachute inherent defect again, to using height, environment, weather without limits, and also simple in structure, easy to operate.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model running condition three-dimensional side view.

Fig. 2 is the utility model unused state, folded sides view.

Among the figure: the rotor that 1. can produce lift; 2. wind wheel blade; 3. wind wheel outer shroud; 4. rotor shaft bearing; 5. pipe link; 6. bracing frame; 7. handle; 8. safety strap.

The specific embodiment

In Fig. 1, the wind wheel outer shroud 3., wind wheel blade 2., 4. the rotor shaft bearing be integral structure.2. wind wheel blade is that 3. certain inclination angle is radial arranges around bearing seat.The multi-disc rotor 1. with wind wheel blade 2. on same horizontal surface, 3. adopt collapsible mode evenly to be fixed on the wind wheel outer shroud goes up, pipe link 5. upper end is connected the rotor shaft bearing 4. on the neck bearing, the lower end fixed handle 7., a bracing frame 6. end is fixed on 1. lower aerofoil of rotor, an end is enclosed within pipe link with ring set and 5. goes up, between ring set and the pipe link certain clearance is arranged, be convenient to rotate, simultaneously, 6. bracing frame plays a part the folding rotor.8. safety strap increases protective effect, prevents the unexpected disengaging of Airlanding device and airborne body.

In Fig. 2,1. rotor folds and is column, is convenient to deposit.

Claims

1, a kind of safe Airlanding device of forming by multi-disc rotor, center wind wheel, bearing, pipe link, bracing frame, handle and safety strap.It is characterized in that: the multi-disc rotor evenly is connected in same plane on the wind wheel outer shroud of center, and the pipe link upper end at right angles links to each other with the rotor shaft bearing, and the lower end is with safety strap and vertical fixing gripping handle.

2, according to the described safe Airlanding device of claim 1, its feature also is: design has slidably the bracing frame of rotation on pipe link, the bracing frame identical steady arm that all distributes with rotor quantity, and the upper end connects the rotor bottom surface, can strut or fold rotor.
