Abstract

The invention relates to an aerosol sampling device, in particular to an aircraft, in particular to a rotor unmanned aerial vehicle-mounted low-energy-consumption aerosol sampling device and an aircraft. The invention aims to solve the technical problems of overlarge sampler volume, overhigh energy consumption and poor representativeness of a sampled product when a rotor unmanned aerial vehicle-mounted aerosol sampling device is adopted for sampling in the existing aerosol sampling and observation. The sampling device comprises a shell, an exhaust pipe, a non-woven fabric filter material, a pressing ring, a pressing plate, a front cover and an air inlet pipe, one end of the shell is open, and the other end of the shell is provided with a bottom plate; external threads are arranged on the outer wall of the open end of the shell, and an annular groove is formed in the inner wall of the open end of the shell along the circumference; the exhaust pipe is mounted on the bottom plate; the non-woven fabric filter material is conical, the opening of the non-woven fabric filter material is pressed at the annular groove by the pressing ring, then the pressing ring is pressed by the front cover and the pressing plate, and the air inlet pipe is arranged on the front cover. The aircraft carries the sampling device and a gas flow type sensor.

Description

technical field [0001] The invention relates to an aerosol sampling device, in particular to an aircraft, especially an aerosol sampling device with low energy consumption carried by a rotor unmanned aerial vehicle and the aircraft. Background technique [0002] Atmospheric aerosols are common substances in the atmosphere, and many pollutants exist in the form of atmospheric aerosols or mixed in atmospheric aerosols. The monitoring and sampling of atmospheric aerosol pollutants is one of the important contents of atmospheric environmental monitoring. Airborne aerosol sampling is the method used to obtain airborne aerosol samples, the basis for detailed laboratory analysis of aerosol samples, and a necessary link in many atmospheric monitoring work. [0003] Among various aircraft-borne aerosol samplers, aerosol samplers based on UAVs (UAVs include fixed-wing UAVs and rotor UAVs), especially rotor UAVs, have developed rapidly in recent years. Environmental monitoring equipm...
