The collection components are arranged on both sides of the collection frame 1, and can extract and collect water samples when the movable plate 3 moves horizontally;

[0026] When it is necessary to collect groundwater, the collection frame 1 is lowered to a suitable position at the bottom of the well or the river channel through the set retractable component, and then the two movable plates 3 on the fixed rod 2 are squeezed by the set propulsion mechanism to make the two movable plates 3 move back and forth relative to each other, and the movable plates 3 will drive the two shifting plates 4 to move back and forth to shift the water below the collection frame 1, so that the garbage impurities floating on the water can be pushed away to keep the groundwater clean. At the same time, the clean water with the garbage impurities pushed away can be extracted and collected through the set collection component, which is convenient for collecting clean groundwater, thereby improving the accuracy of subsequent water sample detection data.

[0027] Specifically, the propulsion mechanism includes a partition 101 arranged on the inner wall of the collection frame 1, a cylinder 102 arranged on the inner top wall of the collection frame 1, a piston rod arranged at the output end of the cylinder 102 and extending downward through the partition 101, a mounting plate 5 arranged at the bottom of the piston rod, and a pressure rod 501 movably arranged between the bottom of the mounting plate 5 and the top of the movable plate 3; after the collection frame 1 is lowered to the bottom of the well or the bottom of the river, the cylinder 102 can be started to drive the mounting plate 5 to move up and down through the piston rod, so that the movable plate 3 can be squeezed back and forth by the pressure rod 501 at the bottom of the mounting plate 5 to move back and forth, so as to drive the moving plate 4 to move back and forth to push away the garbage and impurities in the water.

[0028] like Figure 2 and Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the collection assembly includes a collection box 6 arranged on the side walls at both ends of the collection frame 1, a slide bar 301 arranged on the side wall of the movable plate 3 and extending inward through the collection box 6, a press plug 601 arranged at one end of the slide bar 301 located inside the collection box 6, and an extraction mechanism arranged between the bottom of the collection frame 1 and the collection box 6, a one-way valve is arranged on the top of the collection box 6, and a drain valve is arranged on the side wall of the collection box 6;

The one-way valve can make the reciprocating pressure plug 601 generate suction, and then the water is first pumped into the filter box 7 through the connecting pipe 602, the filter box 7 and the pumping pipe 702. At this time, the pumped groundwater can be filtered again through the filter net 701, so as to further improve the cleanliness of the water sample. The filtered water sample will eventually be extracted into the collection box 6, so as to complete the water sample collection. Finally, the collection frame 1 is lifted by the retractable assembly, and then the water sample collected in the collection box 6 is taken out for detection through the drain valve.

The mounting plate 5 will squeeze the moving plate 3 back and forth through the pressure rod 501 at the bottom thereof to move back and forth, and finally drive the two toggling plates 4 to move back and forth to toggle the water below the collection frame 1, so that the garbage and impurities floating on the water can be pushed away to keep the groundwater clean. At the same time, the moving plate 3 can also The slide rod 301 drives the plunger 601 in the collection box 6 to move back and forth. The one-way valve provided can generate suction for the reciprocating plunger 601, and then the water is first drawn into the filter box 7 through the connecting pipe 602, the filter box 7 and the pumping pipe 702. At this time, the extracted groundwater can be filtered again through the filter net 701 provided, so as to further improve the cleanliness of the water sample. The filtered water sample will eventually be drawn into the collection box 6, thereby completing the water sample collection. Finally, the collection frame 1 is lifted up through the retractable assembly, and then the water sample collected in the collection box 6 is taken out through the drain valve for detection.
