Description

Technical Field

[0001] The utility model relates to the technical field of water environment detection, in particular to a reagent shaking device for water environment detection. Background Art

[0002] Water environment testing is the process of determining the types of pollutants in water bodies, the concentrations of various pollutants and their changing trends, and evaluating water quality conditions, including unpolluted and polluted natural water (rivers, lakes, seas and groundwater) and various industrial drainage. Water quality testing can provide data and information for water environment management and provide a basis for evaluating the water quality of rivers and oceans.

[0003] At present, in the process of water environment testing, after collecting samples, it is usually necessary to mix the sampled water with chemical reagents for reaction, and wait for sufficient reaction for subsequent measurement. In order to speed up the reaction efficiency, the mixture often needs to be shaken. Compared with manual shaking, it is easier to use automated equipment, and multiple reagent tubes can be shaken at a time. However, when the existing shaking device is actually used, the reagent tube is fixed in a relatively simple manner. It is often vertically inserted in a test tube slot connected to the bracket. Due to the various swinging directions during shaking, such as rotation and up and down movement, the reagent tube is easily thrown out of the slot, and the fixing protection effect is poor, which greatly affects the safety of the device when in use.
