The present application solves the problems of low work efficiency, blockage of the pipeline by impurities in the water during sample extraction, and the inability to store the extracted sample. The inlet mechanism removes the impurities filtered by the filter screen when water enters the suction shell, preventing the impurities from blocking the filter screen and affecting water extraction. The spring is used to reset the plastic plate when no water is being extracted, which can squeeze the water in the water storage shell into the suction shell, then impact the filter screen, and then remove the impurities attached to the screen mesh.

The incomplete gear 272 drives the second pinion 283 again, so that the second driving shaft 285 pushes the hollow long plate 244 to rise. At this time, water flows out through the water outlet pipe 2415 and the one-way water outlet valve 2416, and the water outlet pipe 2415 slowly injects water into the inside of one of the storage cups 231. Air is discharged through the air outlet pipe 245, the one-way air outlet valve 247, the second telescopic pipe 248 and the air charging pipe 249. Subsequently, the incomplete gear 272 drives the first pinion 222 again, and the first driving shaft 224 lifts the detector 250 and the air charging pipe 249. The first telescopic pipe 214 rises again. The staff member picks up the storage cup 231 filled with water and places it below the detector 250. Subsequently, a new storage cup 231 is picked up and placed at the water receiving position. Subsequently, the incomplete gear 272 continues to drive the second pinion 283 to pump water, and the piston rod 242 pumps water through the first telescopic pipe 214 again. Because the height of the first telescopic pipe 214 changes, water samples at different depths can be pumped. Subsequently, the detector 250 descends to detect the water quality in the storage cup 231, so that the staff member knows the rapid detection result of the water sample. After detection is completed,The worker places the water detected by the detector 250 below the inflation pipe 249 and places the storage cup 231 below the detector 250 again, and connects the first joint 263 and the second joint 264, so that when the water source is drawn into the long barrel 241, the nitrogen will enter the inflation cavity at the same time, and when the water outlet pipe 2415 discharges water, the nitrogen will be filled into the water source sample through the inflation pipe 249, at this time the sealing ring 2411 is inserted into the sealing groove 232 for sealing, the nitrogen filled in the water carries the VOCs in the water to be discharged through the exhaust pipe 233, and then enters the trapping reagent barrel 236 to be collected by the trapping reagent, so as to realize the collection of VOCs in the water source sample, and the operation is repeated, so that the VOCs samples in the water source at different depths are continuously collected, which is convenient for monitoring, and then transported to the laboratory for detection, so that the detection effect is more accurate.

[0047] The above are preferred embodiments of the present application, not to limit the protection scope of the present application, therefore: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
