Abstract

The invention discloses a multilayer fixed-depth groundwater sampling device for groundwater exploration, which relates to the field of groundwater sampling and comprises a support frame, wherein an installation pipe is rotatably connected to the support frame. After reaching the target depth, the valve mechanism is pulled to open the specific air inlet pipe, and then the air blowing mechanism is used for pushing the transmission mechanism, so that the water pumping plate moves in the water suction box to finish water pumping. Each water absorption box corresponds to a specific depth, and groundwater with different depths can be sampled in sequence, so that the problem that water samples with different depths are difficult to accurately obtain in a traditional sampling mode is avoided. And the whole sampling process is relatively simple and convenient to operate, complex equipment is not required to be repeatedly installed and detached for multiple times, multi-layer depth-fixing sampling can be completed at one time, and the sampling efficiency is greatly improved.

Background In the groundwater surveying work, it is important to accurately obtain groundwater samples with different depths, and the sample data has key significance in the aspects of deep understanding of groundwater distribution, motion rules, water quality characteristics and the like. However, existing groundwater sampling techniques have a number of limitations that make it difficult to meet practical survey requirements. In a traditional underground water sampling mode, sampling equipment with a single depth is generally adopted, and only a water sample with a certain specific depth can be obtained at a time.

Therefore, the development of a novel underground water sampling device capable of solving the problems has important practical significance.
