The sampling slot block 6 is a container that contacts the sampling liquid. The sampling slot block 6 can be conveniently taken out from the inside of the sampling box 1, which is convenient for maintenance and cleaning of the sampling slot block 6 and the sampling box 1.

[0023] like Figure 2-Figure 4 As shown, the mounting member includes: a wedge plate 8, a slide groove is provided at the position corresponding to the opening inside the mounting block 7, the wedge plate 8 is slidably installed in the slide groove inside the mounting block 7, and the wedge plate 8 is used to limit the infusion tube 4 installed on the mounting block 7; a spring 9 is arranged between the wedge plate 8 and the mounting block 7, and the wedge plate 8 is blocked at the opening of the mounting block 7 under the action of the spring 9; a limiting member is arranged in the slide groove of the mounting block 7, and the limiting member is used to cooperate with the wedge plate 8 to limit and clamp the infusion tube 4 placed in the mounting block 7; the limiting member includes: a limiting plate 10, which is slidably arranged in the slide groove of the mounting block 7 through a guide rod 11, the limiting plate 10 is arc-shaped, and the limiting plate 10 is made of a flexible material; a spring 2 12 is arranged between the limiting plate 10 and the mounting block 7, and the limiting plate 10 cooperates with the wedge plate 8 under the action of the spring 2 12 to stably install and limit the infusion tube 4 that penetrates the mounting block 7.

At the same time, the limiting member (including an arc-shaped limiting plate 10 made of flexible material and an auxiliary spring 12) can further enhance the fixing effect of the infusion tube 4 to ensure smooth flow of the liquid without overflowing. As the wastewater continues to flow into the sampling trough block 6, the sampling trough block 6 can be removed from the sampling box 1 and transferred, so that the sampled waste liquid can be taken to the detection site for detection. After completing a sampling task, the sampling trough block 6 can be easily removed for cleaning or replaced with a new container for next use. Similarly, if wear or other problems are found in the internal components of the mounting block 7, the relevant parts can be quickly disassembled for inspection or repair by simple tools, which greatly reduces the long-term operating cost.
