[0023] Please refer to the attached Figure 1-2 A multi-parameter high-altitude data acquisition device includes a rectangular tube 1 connected and fixed on a drone, one end of the rectangular tube 1 is open, and circular holes are provided on both sides of the rectangular tube 1 near the open end, a first bearing 6 is connected and fixed in the circular hole, and a rotating rod 7 is connected and fixed between the two first bearings 6, a plurality of first arc plates 16 arranged equidistantly in an annular surface of the rotating rod 7 are connected and fixed, an arc groove is provided on one side of the first arc plate 16, a second arc plate 18 is inserted in the arc groove, a threaded hole connected and communicating with the arc groove is provided on the side of the first arc plate 16, and a clamping screw 17 for limiting the relative position of the second arc plate 18 in the arc groove is threadedly connected in the threaded hole.

[0024] By using the adjustment structure composed of the first arc plate 16, the second arc plate 18 and the clamping screw 17, the rotation speed of the rotating structure is changed by adjusting the surface contact between the first arc plate 16 and the second arc plate 18 and the air.

[0025] A first gear 5 is connected and fixed on the annular surface of the rotating part, and the annular surface of the first gear 5 meshes with the second gear 4. A side of the second gear 4 away from the first gear 5 is connected and fixed to a reciprocating threaded rod 3, and the annular surface of the reciprocating threaded rod 3 is threadedly connected to the reciprocating plate 2. A second bearing 15 is connected and fixed to the closed end in the rectangular tube 1, and one end of the reciprocating threaded rod 3 away from the second gear 4 is connected and fixed in the second bearing 15.

[0026] A through hole 14 is opened on the inner wall of the rectangular tube 1, and a connecting pipe 12 is connected to the annular surface of the rectangular tube 1, and a data collector 10 is installed in the connecting pipe 12. The connecting pipe 12 is connected to a fixed one-way valve 11 at one end away from the rectangular tube, and is slidably connected to a first sealing plate 13 in the rectangular tube 1. The first sealing plate 13 is fixedly connected to the reciprocating plate 2, and a connecting rod 9 is connected and fixed to one side of the sealing plate close to the open end of the rectangular tube 1. The end of the connecting rod 9 away from the first sealing plate 13 is connected and fixed to a second sealing plate 8 that is in sliding contact with the inner wall of the rectangular tube 1. The first sealing plate 13 is in sliding contact with the through hole 14, and the second sealing plate 8 is in sliding contact with the connecting pipe 12.

[0027] A rotating structure consisting of a first bearing 6, a rotating rod 7 and a first arc-shaped plate 16 is connected and fixed on one side of the open end of the rectangular tube 1, and a reciprocating structure consisting of a first gear 5, a second gear 4, a reciprocating threaded rod 3 and a reciprocating plate 2 is driven to move by the rotating structure. The air flow rate is used to drive the rotating structure to rotate and thus drive the reciprocating structure to move, so that the amount of air contact between the data collector 10 and the air in multiple collection time periods tends to be the same, thereby reducing the error between multiple test data.

[0028] The specific operation process of the utility model is as follows: the drone adjusts the opening end of the rectangular tube to be opposite to the air flow direction, and the air enters from the opening end of the rectangular tube 1, and then flows out from the one-way valve 11. When the air flows in, it drives the first arc plate 16 to rotate, and the rotation of the first arc plate 16 drives the rotating rod 7 to rotate. The rotation of the rotating rod 7 drives the reciprocating structure composed of the first gear 5, the second gear 4, the reciprocating threaded rod 3 and the reciprocating plate 2 to move.

[0029] When the initial position of the reciprocating plate 2 is closest to the open end of the rectangular cylinder 1, the data collector 10 starts to collect data. As the reciprocating plate 2 drives the first sealing plate 13 and the second sealing plate 8 to move, the data collection stops until the second sealing plate 8 moves with the reciprocating plate 2 to the farthest from the sealing end of the rectangular cylinder 1. At this time, air enters through the open end of the rectangular cylinder 1 and flows out from the through hole 14.

[0030] Then the reciprocating plate 2 drives the first sealing plate 13 and the second sealing plate 8 to move back toward the open end of the rectangular tube, the first sealing plate 13 seals the through hole 14, and the second sealing plate 8 moves away from the connecting tube 12 until the reciprocating plate 2 returns to the position closest to the open end of the rectangular tube 1 and starts collecting data again.

[0031] The above description of the utility model in combination with the accompanying drawings is an exemplary description. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as the non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
