An inflatable unmanned helicopter atmospheric gas collection device and high-altitude gas collection method

Abstract

An inflatable atmospheric gas collection device for an unmanned helicopter, connected to the frame of the unmanned helicopter, including a vertical inflation tube with openings at both ends, and an air collection bag with the opening sleeved on the lower port of the vertical inflation tube; There is an inflatable fan installed in the vertical inflatable pipe which is controlled by the remote controller on the ground; the vertical inflatable pipe is connected and fixed with the frame through a horizontal connecting rod; the opening of the gas collection bag is connected with the lower port of the vertical inflatable pipe through an elastic sealing clip fixed. When in use, use the drone to carry the gas collection device to the air to collect the atmosphere, and remotely turn on the inflatable fan to make the air collection bag inflated and automatically separate from the unmanned helicopter under atmospheric resistance. The elastic sealing clip automatically closes the gas collection bag and collects gas under the action of gravity. The bag landed. The invention has short acquisition time and high efficiency, reduces the requirement for the duration of the unmanned aerial vehicle, and has a simple structure, reasonable design, and low cost, effectively solving the problems of complex equipment, inconvenient carrying, and poor automatic effect faced by high-altitude gas extraction.

Description

technical field [0001] The invention relates to the technical field of gas collection equipment, in particular to an inflatable unmanned helicopter atmospheric gas collection device and a high-altitude gas collection method. Background technique [0002] At present, the increase in particulate matter emissions brought about by industrialization affects air quality and is profoundly affecting human beings and the earth's environment. The monitoring of particulate matter is urgent. At the same time, with the development of industry and the improvement of human living standards, air quality is declining year by year. The monitoring of the atmosphere, especially the monitoring of the pollution components in the atmosphere is also becoming more and more important. The traditional monitoring of air pollution components is to install the monitoring equipment in a fixed position for continuous work to monitor the atmospheric conditions there. The main disadvantage of this method is...
