The invention provides a gas acquisition device. By the aid of the gas acquisition device, the problems of large sizes of existing flux chambers which are of cylindrical structures, unsuitability for operation and transportation on water surfaces and poor stability of the existing flux chambers under wind and wave conditions can be solved. The gas acquisition device comprises a flux chamber and a gas acquisition structure. The flux chamber comprises a base structure and a bracket structure, the bracket structure is arranged on the base structure and comprises a plurality of support frames, the support frames are of identical structures, each support frame comprises two side pipes and a connecting pipe, the two side pipes of each support frame are opposite to each other and are connected with each other by the connecting pipe of the support frame, each connecting pipe is positioned on a side of the corresponding side pipe, connecting holes are formed in the connecting pipes, the connecting pipes of the multiple support frames are rotationally connected with one another by the connecting holes, and the end, which is far away from the corresponding connecting pipe, of each side pipe is connected with the base structure; the gas acquisition structure comprises a gas guide pipe and a gas acquisition pipe, and the gas guide pipe and the gas acquisition pipe are at least partially inserted in the flux chamber. The gas acquisition device in an embodiment of the invention has the advantages that the flux chamber can be folded, and accordingly the gas acquisition device is portable and is convenient to operate in water surface environments.
Description
technical field [0001] The invention relates to the technical field of automobile tire design, in particular to a gas collection device. Background technique [0002] Global warming caused by greenhouse gas emissions has also become a major environmental problem facing the world today. With the deepening of research on the greenhouse effect, the greenhouse gas emissions at the water-vapor interface of freshwater systems have also attracted worldwide attention. Raymond et al. According to the monitoring data of 7939 lakes and reservoirs, the global freshwater system emits 2.1×1015gC of greenhouse gas per year to the atmospheric interface, accounting for about 4% of the global net emission, which is higher than the annual terrestrial heterotrophic respiration and fire net emissions produced. [0003] At present, the monitoring methods of greenhouse gas flux at the water-air interface of lakes and reservoirs include gradient method calculation, in-situ or off-line static box m...
