Description

Technical Field

[0001] The utility model relates to the technical field of groundwater detection equipment, in particular to a convenient and efficient groundwater sampler. Background Art

[0002] Groundwater is an important resource that is indispensable for people's survival and social and economic development, and is also an important environmental factor and ecological support condition. With the rapid development of my country's economy and the in-depth development of environmental protection work, the environmental situation has changed significantly. The environmental problems of groundwater pollution have gradually emerged in recent years, and groundwater pollution accidents have occurred frequently. Scientifically understanding and fully mastering the characteristics of groundwater pollution changes is an important basis for the rational development, effective protection and sustainable utilization of groundwater resources, and is the basis for ensuring drinking water safety and reducing and preventing groundwater-related pollution accidents and ecological problems.

[0003] Existing groundwater sampling is divided into organic sampling and inorganic sampling. There are two existing sampling methods: First, the original organic well and the original water extraction equipment (submersible pump) are used to perform standardized sampling of groundwater. However, in this sampling method, organic sampling and inorganic sampling require two samplings in succession, which affects the sampling efficiency. In addition, when sampling is performed through the original water extraction equipment, the water pressure is too high, and bubbles may be introduced into the sampled water source during sampling, affecting the detection effect; Second, sampling is performed through a low-power water pump. The low-power water pump needs to be adapted to the pipeline, which increases the equipment cost. When the qualified water source needs to be pumped for use, a high-power submersible pump is also required to improve the pumping efficiency, which affects the equipment cost while increasing the mobility and portability of the equipment of the entire engineering team.

[0004] For hydrogeologists, time is often tight and tasks are heavy. In actual work, it is difficult to connect the required sampling equipment to the original water extraction equipment of the wells. How to collect groundwater samples conveniently, efficiently and in a standardized manner during field work is also an issue that needs to be addressed urgently. Utility Model Content

At the same time, a regulating valve is set at the second end of the diverter, and the flow rate is controlled by adjusting the branch valve to reduce the water flow pressure and prevent bubbles in the sampled water source. The utility model is not only easy to operate and convenient to carry for field operations, but also does not require precise installation, which can fully improve the field operation efficiency, and can make full use of the original water-taking equipment of the machine-civilian well without the need to install and disassemble the original equipment.
