Specific embodiment
To be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below with reference to
Specific embodiment, the present invention is further explained.
As shown in figs 1 to 6, the present invention provides a kind of equipped with the self-rescue device of drowning unmanned plane for generating buoyancy with gas
Technical solution:
As Figure 1-Figure 2, a kind of equipped with the self-rescue device of drowning unmanned plane for generating buoyancy with gas, structure includes
Rotating propeller blade 1, self-rescue device of drowning 2, support frame 3, unmanned aerial vehicle body 4, lower surface and the support frame 3 of the rotating propeller blade 1
Outer surface is connected, and the upper surface of the self-rescue device of drowning 2 is mutually welded with the lower surface of unmanned aerial vehicle body 4, support frame as described above 3
It is integrated with unmanned aerial vehicle body 4, the self-rescue device of drowning 2 includes oscillating plate 21, elastic element 22, hinge connecting rod
23, thimble 24, sealing ring 25, compressed gas reservoir 26, air bag 27, retaining device 28, outer casing 29, the oscillating plate 21
Upper surface is connected with elastic element 22, and the hinge connecting rod 23 is connect with 24 hinge of thimble, the outer surface of the thimble 24 with
Sealing ring 25 fits, and the side surface of the compressed gas reservoir 26 is equipped with air bag 27, the retaining device 28 and outer casing
29 mechanical connections.
As shown in figure 3, the thimble 24 includes thimble main body 2401, air guiding through hole 2402, ventilation through-hole 2403, the top
Air guiding through hole 2402 is equipped in needle main body 2401, the air guiding through hole 2402 is connected with ventilation through-hole 2403, passes through thimble 24
Interior air guiding through hole 2402 more preferably releases the gas in compressed gas reservoir 26 with ventilation through-hole 2403.
As shown in figure 4, the retaining device 28 includes overhead gage 2801, lower baffle plate 2802, the overhead gage 2801 is under
Baffle 2802 is mechanically connected, and provides release direction by retaining device 28 for the expansion of air bag 27.
As shown in figure 5, the overhead gage 2801 includes overhead gage main body a, link block b, card slot c, the overhead gage main body a
