Description

Water quality detection device based on criticism Technical Field The utility model relates to the technical field of environmental monitoring, in particular to a water quality detection device based on criticism. Background After the existing planning and construction projects are implemented, possible environmental influences need to be predicted and estimated, and countermeasures and measures for preventing or reducing the adverse effects are proposed, namely so-called criticism, and the detection of water quality is an important loop: For the water sample collection in multiple areas and multiple points, water quality detection is needed, wherein before monitoring, the water sample is mixed by adding a precipitant, and then precipitation is carried out to realize solid-liquid stratification, so that supernatant is conveniently extracted; Common water quality monitoring mixing mechanism adopts the reagent pipe fixed knot of fixed specification to construct more, is difficult to compatible reagent pipe of different diameters, length simultaneously. For example, when reagent tubes of various specifications ranging from 10mm to 25mm need to be detected, the conventional equipment needs to frequently replace the clamps or adopt a multi-layer adapter rack, which can result in longer assembly time of single-batch reagent tubes, lower detection efficiency, and can not assemble the next batch of reagent tubes in advance in the mixing process. For example, when a batch of reagent tubes is mixed and enters a precipitation stage, an operator needs to wait for the complete end of the current batch to start clamping the next batch of reagent tubes, so that the equipment has higher idle rate, and the high-frequency detection requirement is difficult to meet.
