Air sampling aircraft and air sampling method

Abstract

The invention provides an air sampling aircraft which comprises a flight main body, a control device and a sampling device which are disposed on the flight main body, wherein the control device comprises an intelligent control module, a direction positioning module which is connected to the intelligent control module and is used to control and adjust the flying direction of the flight main body and to position the sampling device, and a power driving module which is connected to the intelligent control module and is used to driving the operation of the flight main body, and the power driving module comprises a first-grade actuator, a second-grade actuator, a driving motor, a propeller, and a driving device. Because a combined structure of the flight main body, the control device, and the air sampling device is employed, not only air samples can be collected automatically, but also the time and regional restriction is broken through; more importantly, with the automatic technology, notonly air sampling by sampling technicians is convenient, but also the life safety of sampling personnel is protected during air sampling under certain specific conditions such as regions with inaccessible and strategic terrain or a lot of toxic gas.

Description

technical field [0001] The invention relates to an air sampler, in particular to an air sampler and a sampling method for high-altitude air sampling, so as to detect and measure possible pollutants in the high-altitude. Background technique [0002] Air samplers are known in the art. The current conventional air sampling method is mainly to carry out on-site sampling by the staff carrying the air sampler, or to set sampling points at designated places, place high-tech analytical instruments, and directly analyze the obtained air. These two sampling methods have their own advantages and disadvantages. The former has high flexibility, but consumes a lot of time, manpower and material resources. Although the latter has high precision and fast speed, it is not flexible in movement and limited in collection range. The important thing is its high cost, which is basically more than one million RMB. In terms of air sampling in dangerous terrains and harsh environments such as toxic...

Problems solved by technology

[0004] (1) Air sampling has very strict requirements on the surrounding wind speed. Generally, the wind speed needs to be lower than level 3. If the wind speed is too fast, it will affect the sampling, and the data obtained after sampling and analysis will lose its accuracy.

Therefore, fixed-wing aircraft models that cannot hover or fly at low speeds cannot meet the requirements, and the rotor aircraft has strong airflow around it, so it cannot be used for the research of this project.

[0005] (2) At present, the flight of aircraft models requires strong electric energy to provide support. With commonly used aircraft m
