At this time, the water inlet pipe 26 is connected to the connecting pipe 25, and the bottom end of the connecting pipe 25 is engaged with the block 28. The filter plate 29 is fixed. When a sample needs to be drawn, the water pump 21 is started, and water flows into the water inlet pipe 26. Large particles of debris are isolated by the filter plate 29 and discharged through the drain hole 27. The filtered water flows from the connecting pipe 25 through the hose 24 and enters the injection pipe 22 from the output end of the water pump 21. The injection pipe 22 is then injected into the collection pipe 307. This device can effectively isolate debris that is of no reference value during detection, thereby increasing the accuracy of detection. When the sample water source fills the collection pipe 307, the connecting seat 313 is rotated so that the protrusion 23 is aligned with the slot 302. At the same time, the upper fixing plate 306 is pressed, causing the upper fixing plate 306 to move downward along the fixing column 301. The upper fixing plate 306 and the baffle 305 cooperate to compress the spring 303, and the upper fixing plate 306 is rotated so that the connecting seat 313 at the top of the next collection pipe 307 is aligned with the injection pipe 22.
