AI Technical Summary
Technical Problem
Existing groundwater stratification sampling devices cannot sample groundwater at different depths at once, and the samples are easily contaminated by sediment during the sampling process.
Method used
A device was designed that includes a hollow graduated storage tube, a sampling tube, a water inlet assembly, a partition plate, an electromagnet, a drain pipe, and a plug. The sample is sealed by controlling the opening and closing of the partition plate with the electromagnet, the filter screen is used to prevent mud and sand contamination, and the sampling process is accelerated by a vibration motor.
Benefits of technology
This technology enables multi-level sampling of groundwater at different depths, preventing sample contamination and improving sampling speed and accuracy.

Abstract
本发明涉及地下水取样技术领域，具体为一种地下水样分层取样装置，其包括操作控制器，操作控制器底端固定连接有中空刻度置物管，中空刻度置物管底端固定连接有竖直设置的取样管，取样管内侧安装有多组呈均匀分布的进水组件；本发明中，通过设置的中空刻度置物管、取样管、进水组件、进水开关、分隔板、电磁铁、排水管和堵头，在进行地下水取样时启动电磁铁，电磁铁吸引铁质挡板下降，此时外界的地下水通过进水管和固定管上的通孔进入两个分隔板之间的腔室中，取样结束后关闭电磁铁，复位弹簧复位使两个分隔板之间的腔室重新被密封，这种设计能够对采样的地下水进行封闭，防止样品被污染，且能够对多层地下水进行取样。
