[0002] Water quality testing is an important monitoring object in environmental monitoring, mainly involving the testing of domestic wastewater, industrial wastewater, drinking water, groundwater, industrial cooling water, seawater, etc. When testing various liquids, the samples tested determine the subsequent test results. Therefore, sampling is a relatively important step. It not only has strict requirements on sampling personnel, but also has extremely high requirements on sampling equipment. When sampling, it is necessary to ensure the accuracy of sampling, the representativeness of the collected samples, and to ensure that the samples will not be contaminated during the collection process.
[0003] Common liquid collection devices include a bracket, a base, a clamp and a float. The clamp is fixed on the bracket and is used to fix the upper end of the sampling bottle. However, the clamp of the liquid collector currently used is generally fixed to the bracket and the height cannot be adjusted. When using sampling bottles of different models, the clamp cannot play a good role in fixing and positioning, which will cause the bottle body to tilt during the sampling process, causing the collected samples to flow out and pollute the collected samples. In order to solve the problem that the clamp of the existing liquid collection device cannot be adjusted and the sampling bottle is not firmly positioned, the designer has made improvements to the currently used liquid collection device to achieve that the same collection device can be applied to multiple types of sampling bottles, and the sampling bottle can be positioned stably and the bottle body is not prone to tilting.
