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

Abstract

The invention discloses an unmanned helicopter atmospheric gas collecting device and a high-altitude gas collecting method. The unmanned helicopter atmospheric gas collecting device comprises a gas inlet funnel which is mounted upside down, a gas collecting bag on the neck of the gas inlet funnel, and a weight block which is connected with the gas collecting bag, is separated from a helicopter body and drives a gas collecting device to fall down in a later gas collecting period; the opening of the gas collecting bag is fixedly connected with the neck of the upper end of the gas inlet funnel through an elastic rubber band; the neck of the gas inlet funnel is communicated with the gas collecting bag; the opening of the funnel is communicated with the atmosphere. When the unmanned helicopter atmospheric gas collecting device is in use, the gas collecting device is carried to the air by using the unmanned helicopter for collecting atmosphere; after the gas collecting bag is inflated, the gas collecting gas is automatically separated from the unmanned helicopter under the resistance of the atmosphere, and is automatically closed by the elastic rubber band and a sealing ball or an elastic sealing clamp; the overall device falls down under the action of the gravity of the weight block. The unmanned helicopter atmospheric gas collecting device is simple in structure, reasonable in design, low in cost, low in technical operating requirement, short in collecting time and high in efficiency; the requirement on cruise duration of the unmanned helicopter is lowered; the technical difficult problems of complex equipment, inconvenience in carrying, poor automatic effect and the like of high-altitude gas collecting are effectively solved.

Description

technical field [0001] The invention relates to the technical field of gas collection equipment, in particular to an 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 that it ca...

Problems solved by technology

[0004] The purpose of the present invention is to provide an unmanned helicopter atmospheric gas collection device and a high-altitude gas collection method, which solves the problems of complex and large structure, high production and operation costs and high technical requirements of the high-altitude gas collection equipment in the prior art; also solves the problems of the prior art Atmospheric sampling is carried out by configuring samplers on unmanned helicopters. It takes at least one hour to sample at each altitude, low sampling efficiency, long sampling time at multiple altitudes, and high requirements for drone endurance.
