Pollutant is gone out in bag；After having washed away automatic inflation type sampler bag, by evacuating air in bag, it is then shut off and is connected with sampler bag
Solenoid valve.2. after sampling preparation, unmanned plane is let fly away, unmanned plane is made first to climb to default maximum height (1km-
2km), it is then sampled during unmanned plane declines, to reduce the sample skyborne residence time being collected, reduces bag
Interior aerosol loss.3. unmanned plane hovers after reaching specified height of sampling, air inlet main road is washed away first with emptier, is then closed
Emptier is closed, the solenoid valve being connected with specified sampler bag, automatic inflation type sampler bag inflation sampling, after the completion of sampling are opened
Close coupled solenoid valve.4. unmanned plane reaches other height, air inlet main road is similarly first washed away, then acquire the height
Under aerosol sample.5. after the completion of the collection of whole sampler bags, unmanned plane landing.
After unmanned plane landing, the SP-AMS (black carbon aerosols mass spectrograph) and SP2 (individual particle of surface-based observing station are utilized immediately
Black carbon photometer) etc. equipment different height aerosol sample is analyzed, to obtain black carbonaceous amount Spectral structure, mixed state and packet
The vertical distribution information of covering layer chemical component, while also needing to be safeguarded after unmanned plane landing, including replacement battery, replacement sampling
Bag etc..
Currently used unmanned plane and the sampling of aerosol for being tethered at motorboat platform load generally at 2-10 kilograms, in the present invention
Device all uses light-weight design, using 10 automatic inflation type sampler bags, total weight within 3 kilograms,
Within the scope of unmanned plane and the carrying for being tethered at motorboat.
Aerosol sample has dissipation and sedimentation loss in automatic inflation type sampler bag, and unmanned plane is from starting to sample drop
Landing face unloading automatic inflation type sampler bag carries out analysis and takes around 20 minutes or so.Fig. 7 is illustrated for two kinds of inflatables
Sampler bag (2 liters and 5 liters), when the different-grain diameter aerosol particle object of theoretical calculation stops different in automatic inflation type sampler bag
Between after remaining proportion.It can be seen that for 400 nanometers of (the partial size upper limit that SP2 measures mixed state) particulate matters, at 2 liters
Residue after twenty minutes is stopped in inflatable sampler bag remaining 50% in 5 liters of inflatable sampler bags, all to meet subsequent close to 40%
Analysis needs.In fact, because mixed state and chemical component are individual particle physicochemical characteristic, in the feelings of particle concentration abundance
Under condition, loss of the particulate matter in sampler bag will not influence measurement accuracy.
