Embodiment 1

[0046] Please refer tofigure 1 , this embodiment provides a groundwater measurement device, including a measurement device. The two vertical lines on the left and right in the figure represent a single wellbore.

[0047] The measuring device includes a mounting part 4, a first imaging part 6, an ultraviolet light source 7, a direction indicating part 5 and a first injection part 8 for providing a liquid containing fluorescein.

[0048] Wherein, the first imaging part 6, the ultraviolet light source 7, the direction indicating part 5 and the first injection part 8 are all arranged on the mounting part 4, and the final indication direction of the direction indicating part 5 under static conditions remains unchanged all the time. The part 8 is used to inject the liquid containing fluorescein into the groundwater to be tested, and the first camera part 6 is used to record the flow of the liquid with the groundwater to be tested under the irradiation of the ultraviolet light source...

Embodiment 2

[0084] Please refer to figure 2 , the present embodiment provides a kind of groundwater measurement equipment, which increases the second camera 9 which is all arranged on the mounting part 4 and the second injection part 12 for providing the liquid containing fluorescein on the basis of the first embodiment , the second imaging part 9 and the second injection part 12 are parallel to each other and relatively fixed. It should be noted that in this embodiment, the flow direction of the groundwater is measured through the combination of the first camera 6 and the first injection part 8, and on this basis, the second camera 9 is used to obtain the new data injected by the second injection part 12. The moving distance of the fluorescein-containing liquid within the measurement time is used to measure the specific water flow velocity of the groundwater to be tested.

[0085] For reference, the above-mentioned second imaging component 9 and the second injection component 12 are bo...

Abstract

Embodiments of the present invention provide a groundwater measurement device and a measurement method, which relate to the technical field of groundwater measurement. The measuring device includes a mounting part, a first imaging part, an ultraviolet light source, a direction indicating part and a first injection part. The first imaging part, the ultraviolet light source, the direction indicator and the first injection part are all arranged on the mounting part. The final indication direction of the direction indicator under static conditions remains unchanged. The first injection part is used to inject the groundwater to be measured. The liquid containing fluorescein is injected, and the first camera is used to record the flow of the liquid with the groundwater to be measured under the irradiation of the ultraviolet light source, so as to obtain the angle between the movement direction of the liquid and the direction indicated by the direction indicator. The specific flow direction of groundwater. The measuring device has a simple structure and convenient measuring method, and can obtain the flow direction of the groundwater to be measured by analyzing the flow of the liquid containing fluorescein injected into the groundwater to be measured along with the groundwater to be measured.

Description

technical field [0001] The invention relates to the technical field of groundwater measurement, in particular to a groundwater measurement device and a measurement method. Background technique [0002] Groundwater seepage velocity and flow direction are not only two important dynamic parameters in the study of groundwater seepage field, but also the main parameters for determining hydrogeological parameters such as aquifer permeability coefficient and seepage flow. The traditional method of measuring groundwater flow velocity and flow direction is to arrange boreholes along the flow direction on the basis of understanding the geological conditions of the studied area and the approximate groundwater flow direction, and then measure the groundwater flow velocity through pumping tests. The method has a large workload, a long construction period, and complicated processes. [0003] At present, the devices for measuring fluid flow rate can be mainly divided into mechanical type ...
