[0018] Through the telescopic sampling mechanism provided in the present invention, the servo motor drives the transmission shaft to rotate. At the same time, the first cam and the second cam are synchronously driven to rotate by two belt pulleys. During the rotation of the first cam, it contacts the first track wheel. Therefore, it can drive the bottom of the first crank to drive the first slide rail inside the extension plate to drive the liquid extraction cylinder to move horizontally along the first support rail frame. At the same time, during the rotation of the second cam, it contacts the second track wheel on the second crank. When it contacts the straight position of the second cam, one end of the second crank will drive the second slide rail to descend along the second support rail frame, thereby driving the liquid extraction cylinder to move downward. The movements in the horizontal direction (X-axis) and the vertical direction (Z-axis) are respectively controlled by two cams with different shapes, enabling the liquid extraction cylinder to not only achieve horizontal movement but also vertically descend as needed, completing multi-directional positioning sampling, adapting to the water quality stratification and regional differences existing in different water areas, and avoiding poor data representativeness caused by a single sampling position.

[0045] Working principle: When the servo motor 39 is started, its output shaft drives the transmission shaft 12 to rotate clockwise through the second pulley 40 and the first pulley 13. One end of the transmission shaft 12 is fixedly connected to the turntable 11, and the other end is fixed with the second cam 14. At the same time, the first pulley 13 is also fixed on its outer wall. The turntable 11 drives the first cam 10 fixedly connected thereto to rotate synchronously. During the rotation of the first cam 10, the outer wall contour thereof continuously contacts the first track wheel 9. The first track wheel 9 is fixed in the middle of the first crank 7. The change of the cam curve pushes the first crank 7 to swing. The bottom of the first crank 7 is rotatably connected to the extension plate 6. The extension plate 6 is fixedly connected to the first slide rail 5. The first slide rail 5 is slidably connected to the first support rail frame 4, thereby driving the liquid extraction cylinder 25 to horizontally move along the X-axis direction. When the second cam 14 rotates, its outer wall continuously contacts the second track wheel 15. The second track wheel 15 is rotatably connected to the second crank 16. The other end of the second crank 16 is connected to the track wheel 19 through the fixed shaft 18. The track wheel 19 is nested in the track frame 20. When the second crank 16 is pushed to rotate by the contour change of the second cam 14, the track wheel 19 slides inside the track frame 20, thereby driving the second slide rail 21 to move up and down along the Z-axis direction. The second slide rail 21 drives the connected second support rail frame 22 and the back plate 23 to vertically descend as a whole. One side of the back plate 23 is fixed with the liquid extraction cylinder 25. Therefore, the vertical falling action of the liquid extraction cylinder 25 from top to bottom is realized, and the target water body can be accurately approached. One side of the extension plate 6 is connected to the first spring 27, which plays a role of flexible traction and reset during the horizontal driving process of the first crank 7. The front of the second crank 16 is connected to the second spring 29, and the bottom is connected to the bottom frame 30, which controls the softness of the vertical descent and the reset function. After the liquid extraction cylinder 25 descends to the target water layer, the water sample is automatically extracted. The upper end of the liquid extraction cylinder 25 is provided with a return pipe or an interface, which is aligned with a plurality of liquid placement holes 41 provided at the top of the fixed disk 1. The water sample is introduced into the liquid placement holes 41 and flows into the lower liquid placement cylinder 42. The water samples at different sampling points can be stored in different regions, ensuring strong representativeness and clear levels. If it is necessary to adjust the overall sampling angle or area, the bottom reduction motor 38 can be started. The reduction motor 38 drives the gear 37 through the output shaft. The gear 37 meshes with the annular internal gear 36 fixed inside the bottom rail 34, realizing the rotation adjustment of the middle seat plate 2 around the fixed disk 1, driving the entire sampling structure to change the angle, and realizing the cyclic sampling of multi-directional waters.
