[0038] When using the present invention, first place the connecting frame 1 at the groundwater sampling position, then guide the connecting rope 58 through the first roller 2 and the second roller 4, slowly release the connecting rope 58 downward, and lower the shell 50 into the groundwater. Through the action of the first spring 3, the first roller 2 on the slider is kept in a relative position, so that the connecting rope 58 is kept in a central position. When the shell 50 is lowered, the air pump 54 can be started to inhale air through the air pipe 55 and the second connecting pipe 56, so that the air pump 54 passes the gas into the discharge pipe, and then enters the air bag 57 from the discharge pipe to expand the air bag 57.

After the upper water body sampling is completed, the air pump 54 is turned off to shrink the air bag 57, and then the connecting rope 58 is released again to make the outer shell 50 sink to different depths of the water body for sampling. The release length of the connecting rope 58 can be known through the scale bar, and then the depth of the outer shell 50 in the water body can be judged. Initially, the sampling bottle 618 is located below the medicine tube 62, so that the medicine tube 62 adds the preservative into the sampling bottle 618. After the water sample is transported upward through the first connecting tube 53, the water sample enters the water outlet pipe 60, driving the connecting impeller 63 to rotate, causing the first rotating column 64 to rotate, and the second rotating column 66 to rotate through the belt 65, driving the connecting missing gear 67 to rotate and the first gear 69 to rotate, so that the third rotating column 68 drives the trigger block 610 to rotate and squeeze the guide hollow column 611 to move upward, and the second spring 612 is squeezed and contracted, so that the guide hollow column 611 triggers the guide column 613 to rotate, driving the first rotating disk 614 to rotate, so that the sampling bottle 618 rotates from the bottom of the medicine tube 62 to the bottom of the water outlet pipe 60, and a part of the water sample is discharged from The outlet pipe 60 discharges into the sampling bottle 618. After the water sample at this depth is discharged, the connected impeller 63 stops rotating, thereby causing the second spring 612 to rebound, driving the guide hollow column 611 to move downward and reset. At this time, the guide column 613 is not triggered to rotate. After collecting the water sample at the next depth, the first rotating disk 614 rotates again, and the next sampling bottle 618 is switched to the bottom of the outlet pipe 60 for water sample collection. While the first rotating disk 614 rotates, the second gear 616 meshes with the fixed gear 617 to rotate the rotating placement rack 615, driving the sampling bottle 618 to rotate, and mixing the water sample and the preservative evenly, thereby achieving the effect of automatically adding the preservative and automatically mixing the preservative and the water sample evenly, saving manpower, and improving the efficiency of groundwater sampling.

[0040] By using the winding mechanism 7 of the present device, the connecting rope 58 can be automatically released, so that the guide clamping disks 72 move away from each other, the third spring 73 is squeezed and contracted, and then the coil frame 74 is placed between the guide clamping disks 72, and then the guide clamping disks 72 are released, and the third spring 73 rebounds, so that the guide clamping disks 72 move closer to each other to clamp the coil frame 74. When the connecting rope 58 needs to be released, the motor 75 is started to make the third gear 76 and the fourth gear 77 mesh and move, so that the second rotating disk 71 rotates, driving the coil frame 74 to rotate, and releasing the connecting rope 58, thereby automatically releasing the connecting rope 58 and saving manpower.

[0042] The cleaning mechanism 8 of the device can be used to clean the filter 510. After the water sample enters the second connecting pipe 59, it pushes the rotating impeller 81 to rotate, causing the cleaning column 82 to rotate and scrape off the impurities on the filter 510, thereby cleaning the filter 510 and preventing the filter 510 from being blocked. When the rotating impeller 81 rotates, it cooperates with the fixed impeller 80 to guide the water sample and realize the effective transportation of the water sample.

[0043] like Figure 1 and Fig.12As shown, a detection mechanism 9 is also included. The detection mechanism 9 includes a connecting bracket 90 and a sensing probe 91.
