Abstract

The invention relates to a sampling device, in particular to a layered sampling device for underground water monitoring. The invention aims to provide the layered sampling device for underground water monitoring, which can be used for sampling water at different layers and improving the detection accuracy. The layered sampling device for underground water monitoring comprises a sampler, a lowering mechanism and a placing mechanism, the sampler is fixedly connected to a component of the lowering mechanism, and the placing mechanism is fixedly connected to a component of the lowering mechanism. A worker controls an output shaft of a servo motor to rotate positively and negatively to loosen or wind up a pull rope, so that the sampler can descend into underground water for sampling, and then the sampler is pulled out upwards through the pull rope, and the sampling effect can be achieved.

Description

technical field [0001] The invention relates to a sampling device, in particular to a layered sampling device for groundwater monitoring. Background technique [0002] With the development of social economy, scientific progress and the improvement of people's living standards, people's water quality requirements for drinking water continue to increase, and drinking water quality standards are also continuously developed and improved accordingly. Therefore, it is necessary to detect hydrology and pollution source discharge, and then solve and improve Water quality problems. [0003] When detecting the discharge of hydrology and pollution sources, groundwater is often monitored. The monitoring method is usually to collect samples of groundwater, and then the scientific research personnel will test and analyze the groundwater samples to obtain research results, so as to propose to improve water quality or reduce water quality. Pollution scheme; Most of the existing groundwater...
