Description

Technical Field

[0001] This invention relates to the technical field of hydrogeology, specifically to a hydrogeological pumping test device. Background Technology

[0002] Hydrogeological pumping tests are a core field technique for accurately obtaining key parameters such as aquifer permeability and storage capacity, and for assessing groundwater resources and environmental impact. During the test, strict adherence to specifications is required for well flushing, constant-flow pumping, and the collection of representative groundwater samples over time for subsequent physicochemical analysis. With increasingly stringent environmental protection and resource management requirements, higher standards are being placed on the standardization of pumping test procedures, sampling efficiency, and data reliability.

[0003] Currently, mainstream pumping test sampling methods still heavily rely on manual operation. Well-washing processes often depend on experience or simple timed operations, lacking objective, real-time monitoring methods for water quality stability. During sampling, technicians must manually adjust valves to control the flow rate and use sampling bottles to directly collect water samples at the outlet. This process has significant drawbacks: First, manual operation makes it difficult to accurately maintain a constant sampling flow rate and easily introduces human error; second, open sampling may lead to sample evaporation, contamination, or the generation of bubbles, affecting representativeness; third, for samples requiring fixatives or rinsing, subsequent pretreatment steps are cumbersome and time-consuming, and cross-contamination is prone to occur between different sample bottles; fourth, the entire sampling process is inefficient, especially when multiple time-series samples need to be collected continuously, resulting in high labor intensity and difficulty in ensuring operational consistency and traceability.

[0004] Therefore, in view of the prominent problems of existing technologies such as reliance on manual labor, cumbersome operation, low efficiency, and difficulty in ensuring the consistency of sample quality, there is an urgent need to develop an integrated device that can realize intelligent well washing judgment, precise flow control, and integrate automatic sampling and pretreatment functions.

After the well is washed, water samples can be taken. The steps for taking water samples are: opening the cap, moistening the bottle, adding the additive, taking the sample, and closing the cap. The controller receives the image information of the sample bottle 35 taken by the camera 343 and adjusts the steps for taking water samples after analysis, such as canceling the moistening or adding the additive.
