Atmosphere collecting device for inflatable unmanned helicopter and altitude gas collecting method

Abstract

The invention relates to an atmosphere collecting device for an inflatable unmanned helicopter. The device is connected to a frame of the unmanned helicopter. The device comprises a vertical inflatable tube opened at two ends and a gas collecting bag sleeving the lower end opening of the vertical inflatable tube; the vertical inflatable tube is internally provided with an inflatable fan which is controlled to start or stop through a ground remote controller; the vertical inflatable tube is fixedly connected with the frame through a horizontal connecting rod; the opening of the gas collecting bag is fixedly connected with the lower end opening of the vertical inflatable tube through an elastic sealing clip. In use, the unmanned helicopter carries the gas collecting device to collect atmosphere in air and remotely controls to open the inflatable fan, so that the gas collecting bag inflated is automatically separated from the unmanned helicopter under atmospheric resistance. The elastic sealing clip automatically closes the gas collecting bag and the gas collecting bag drops under the action of the gravity. The device provided by the invention is short in collecting time and high in efficiency, and the requirement on duration of flight of the unmanned helicopter is reduced. Moreover, the device is simple in structure, reasonable in design and low in cost and effectively solves the problems that in altitude gas collection, equipment is complex, inconvenient to carry, poor in automatic effect and the like.

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...
