AI Technical Summary

Technical Problem

Traditional water environment testing devices lack pretreatment functions, which leads to impurities clogging the testing equipment during the collection process, affecting the accuracy of the test results, increasing the workload of laboratory pretreatment, and reducing testing efficiency.

Method used

A pretreatment sampling device for water environment detection and analysis was designed, which includes a coarse filter, a medium-efficiency filter and a fine filter to achieve multi-stage filtration. Combined with a storage bottle and a control system, preliminary filtration and separation are completed on-site to ensure sample quality.

Benefits of technology

By removing impurities through multi-stage filtration, the reliability of test data is improved, the workload of laboratory pretreatment is reduced, the testing efficiency is increased, and the cost is reduced.

Abstract

This utility model relates to the field of environmental monitoring technology, specifically a pretreatment sampling device for water environment detection and analysis, including a base, a support frame, a control system, a sampling head, a winding device, a pretreatment device, and a moving device. The support frame is installed on the bottom wall of the base, and the control system is installed on the side wall of the support frame. The sampling head is installed at the end of the support frame away from the base through the winding device. A liquid storage chamber is opened in the upper part of the sampling head, and a sampling tube is installed at the top of the sampling head. A water pump is installed on the outer wall of the sampling tube. The control system controls the electric valve to open the output end of the corresponding transmission tube according to the set stratified sampling parameters. The filtered water sample flows into the corresponding storage bottle through the transmission tube, realizing the independent storage of samples from different water layers. Each set of storage bottles records its corresponding sampling depth information.
