[0035] During the detection, by starting the extraction pump 20, the extraction pump 20 will extract the extraction tube 12 connected to the connector 11. Since the extraction tube 12 is connected to the sample storage cylinder 17, the air pressure in the sample storage cylinder 17 is reduced, and the tail end of the flexible tube 18 on the sample storage cylinder 17 is connected to the sampling tube 9. At this time, the river water in the sampling tube 9 will flow into the sample storage cylinder 17 along the flexible tube 18. When the river water floods the extraction tube 12, the river water will be drawn into the extraction pump 20 through the extraction tube 12, and then transported to the detector 19 through the extraction pump 20. The river water can be detected by the detector 19. When there is pollution, the detector 19 will send a signal to the detection platform. When the staff is checking, since the connection point of the extraction tube 12 with the sample storage cylinder 17 is higher than the flexible tube 18, some river water will remain in the sample storage cylinder 17. The staff only needs to extract and test the remaining river water in the sample storage cylinder 17 in the sampling box 3 to quickly know which area of ​​the river channel is polluted.

[0036] The protective net 10 at the bottom of the sampling tube 9 can prevent garbage in the river from entering the sampling tube 9 and clogging it. At the same time, the protrusions 25 on the outside of the protective net 10 can prevent large pieces of garbage from blocking the outside of the protective net 10 and making it impossible to pump water.
