The invention discloses a modular gas sampling unmanned aerial vehicle. The modular gas sampling unmanned aerial vehicle comprises an unmanned aerial vehicle main body, a modular box body and a gas collecting device. The modular box body can be installed and replaced on the same unmanned aerial vehicle and is used for sampling three objects including gas, water and soil. The gas collecting device is installed in the modular box body and can achieve gas sampling. The gas collecting device and the unmanned aerial vehicle body are powered by the same power source, and the gas collecting device comprises a sampling pipe, a gas collecting bottle, a one-way electromagnetic exhaust valve, a connecting pipe, a selective three-way scavenging valve, a gas collecting tank and a motor. The gas collecting tank comprises a rubber piston, a fixing shaft, a supporting frame, a connecting rod, a rolling bearing, a shaft arm and a rotating shaft. The rubber piston is connected with the shaft arm through the connecting rod, and the motor drives the shaft arm to rotate to achieve up-and-down movement of the rubber piston, so gas suction and exhaust are achieved. The modular gas sampling unmanned aerial vehicle can collect a gas sample at a specified height and remove air impurities, so that the sampling result is accurate, the operation is convenient, and the realizability is high.
Description
technical field [0001] The invention relates to the technical field of air sampling, in particular to a modular gas sampling unmanned aerial vehicle. Background technique [0002] As the global air pollution becomes more and more serious, the tasks of air pollution detection and control in various regions of my country are still very serious. UAV has the advantages of real-time and comprehensive monitoring, rapid response, and is not restricted by the monitoring subject. [0003] When the current UAV is sampling high-altitude gas, there is a problem that the original residual gas in the sampling tank will affect the detection result, resulting in too large error in the detection value; therefore, a modular gas sampling UAV is proposed. Contents of the invention [0004] The purpose of the present invention is to provide a modular gas sampling drone, which can eliminate gas interference and effectively improve the accuracy of gas sampling. [0005] In order to achieve the...
