[0025] Specifically, as Figures 1 - 5As shown, a double-headed motor 11 is fixedly embedded in the fixed seat 2. Output ends of the double-headed motor 11 are fixedly connected with winding rollers 12 respectively. Tops of the pulling ropes 3 all extend into the fixed seat 2 and are wound around the winding rollers 12. Bottom ends of the pulling ropes 3 are each divided into two strands. The number of connection points between the pulling ropes 3 and the top end of the housing 4 is 4. The double-headed motor 11 can drive the winding rollers 12 to rotate, so that the winding rollers 12 can store and release the pulling ropes 3, and further the housing 4 can move up and down.

[0026] Specifically, as Figures 1 - 5 shown, a rotating motor 13 is fixedly arranged on the inner wall of the top end of the housing 4. An output end of the rotating motor 13 is fixedly connected with the top end of the support 5. A rotating groove 14 is annularly formed on the inner wall of the lower part of the housing 4. A rotating ring 15 is rotatably arranged in the rotating groove 14. An inner wall of the rotating ring 15 is fixedly connected with an outer wall of the support 5.

Then, the cylinder 9 is used to push the pressing plate 10 downward, so that the pressing plate 10 pushes the corresponding sampling cylinder 6 downward, and then the water liquid enters the sampling cylinder 6 through the water inlet hole 7. At this time, the sampling cylinder 6 will drive the slider 17 to squeeze the spring 18 downward. Then, the cylinder 9 drives the pressing plate 10 to reset, and at the same time, the spring 18 pushes the slider 17 and the sampling cylinder 6 to reset, thus completing the sampling. When the sampling is completed, the valve on the sampling cylinder 6 is opened, so that the water liquid in the sampling cylinder 6 can be discharged through the liquid outlet pipe 8.
