Method and device for multi-directionally collecting water samples

Abstract

The invention relates to a novel method for measuring underground water flowing direction in the field of geological engineering, hydrological water resource, water resource protection and the like, in particular to a method and a device for multi-directionally collecting water samples. The method fixedly connects more than two water sample collectors capable of collecting water samples at the same specific depth to the periphery of a positioning block, and water sample collecting holes set by at least two water sample collectors in the water sample collectors fixed on the positioning block have different water inletting directions so as to collect the water samples in the different directions and at the specific depth. Therefore, through the technical proposal, the device and the method can effectively prevent the mixing of water samples at the non-specific depth in the process of putting the collector, and only collect the water samples at the specific depth and in different directions. In addition, the device for multi-directionally collecting the water samples has the characteristics of convenient carrying and use, flexible and reliable manual operation, difficult damage, small volume and the like.

Description

technical field [0001] The invention relates to a method and a device for collecting water samples from multiple directions, and belongs to the technical fields of geological engineering, groundwater science and engineering, water conservancy engineering, hydrology and water resources, water environment protection and the like. Background technique [0002] When measuring the flow direction of water, a certain tracer can be put into the water, and the tracer will flow downstream with the flow of water, so that the concentration of the tracer in different directions in the water is different. Concentration calculates the direction of water flow. [0003] It is very simple and easy to simply collect water samples on the surface of groundwater or the surface of surface water bodies, but it is very difficult to collect water samples in different directions at a specific depth below the surface of groundwater or surface water bodies, because before the collector is put into a spe...

AI Technical Summary

Problems solved by technology

The structure of the sampler is relatively complex, the performance is unstable, and the depth that can be taken is limited, generally not exceeding 50m depth

[0007] Therefore, for now, there is no special multi-directional water sample collection device or method, which can prevent water samples from being mixed with non-specific depths during the release of the collector, and only collect water samples at specific depths and in different directions. This has greatly limited the development of science and technology in the field of related water body research, and is a major technical problem that needs to be solved urgently in this field.
