Embodiment 1
[0023] A collection rod for atmospheric sampling, the structure when it is deployed and the schematic diagram of the structure when it is deployed from A-A to look down are as follows figure 1 , figure 2 As shown, that is, the collection rod used for atmospheric sampling includes 5 sections of stainless steel tubes 11, 12, 13, 14, and 15 that are gradually reduced in diameter. The length is 2000 mm, the wall thickness is 1 mm, and the inner diameter is respectively 26mm, 22mm, 18mm, 14mm, 10mm, and the two ends of each section of stainless steel pipe are symmetrically opened with 3mm screw holes at a distance of 30mm from the port. It is used for connecting two adjacent stainless steel pipes through stainless steel bolts. One thick end diameter is 25mm, 30cm long stainless steel cone 4, 5 stainless steel bolts 21, 22, 23, 24, 25 with a length of 32mm and a diameter of 3mm; 4 stainless steel drills 71, 72, 73 with a length of 500mm and a diameter of 10mm , 74, 4 nylon ropes 6...

Abstract
The invention discloses an acquisition rod for atmospheric sampling, and comprises five stainless steel pipes with equal length and gradually reduced pipe diameters, wherein the screw holes are symmetrically opened in each stainless steel pipe, and the distance between each screw hole and a corresponding end of the stainless steel pipe is 30 mm, one stainless steel awl, five stainless steel bolts with identical specification, four stainless steel prickers with same specification, four nylon cords of same specification, one red indication bulb, one bulb pedestal and three sampling heads. When the acquisition rod is used, each two stainless steel pipes with adjacent calibers are vertically and flexibly connected by one stainless steel bolt, and the acquisition rod is directly and vertically fixed on the ground of sampling points through the stainless steel awl, and after used, the five stainless steel pipes are folded into the stainless steel pipe with the largest pipe diameter. Compared with the traditional sampling rack, the acquisition rod for atmospheric samplin has the advantages of facilitated production, structure, installation and folding and low cost; the product can be used repeatedly and moved easily, and the sampling cost is reduced simultaneously; the sampling position can be arranged flexibly.
Description
technical field [0001] The invention relates to a collection rod for atmospheric sampling, which belongs to the field of atmospheric science. Background technique [0002] When studying the vertical change of atmospheric chemical composition, it is often necessary to collect samples at different heights. The usual method is to collect materials nearby: collect materials from nearby tall buildings, towers, and trees; The former is simple and trouble-free, but the reliability of the sample is poor, because these objects will affect the material distribution of the air; the sample reliability of the latter is high, but the total cost of sampling is also high. In order to solve the above-mentioned contradiction, the present invention is proposed. Contents of the invention [0003] The object of the present invention is to provide a collection rod for atmospheric sampling in order to solve the above-mentioned technical problems such as the reliability of atmospheric sample c...
