Abstract

The invention provides an integrated sampling device for underground water. The integrated sampling device comprises a sampling device main body, a piston pump and a filter, wherein the sampling device main body is used for collecting underground water, the piston pump is connected with the sampling device main body, and the filter is used for filtering underground water; a sampling bottle for sampling is connected to the filter; the piston pump comprises a pump body, a push-pull rod and a piston, and the piston is arranged in the pump body; the pump body is of a hollow structure, an inner partition hole board for dividing the inner part of the pump body into a containing cavity and a water storage cavity is arranged in the pump body, the containing cavity is used for the up-down movement of the piston, and the water storage cavity is used for storing cavity; a water inlet pipe communicated with the water storage cavity is arranged on the pump body and is connected with the sampling device main body; and the lower end of the push-pull rod is connected with the piston through a penetration hole formed in the pump body. The integrated sampling device for underground water has the beneficial effects that the application range is extended, particularly for the middle-low permeability water-bearing layers, the well drilling cost and the power cost of a high-power pump are lowered, the pretreatment processes are integrated, the operation is convenient and efficient, and the properties of water sample are preserved.

Description

technical field [0001] The invention relates to the technical field of groundwater sampling devices, in particular to an integrated groundwater sampling device. Background technique [0002] Groundwater is an important water resource in my country, especially for coastal cities, inland cities and large and medium-sized cities in the north. However, with the sharp increase in water demand for industrial and agricultural production and living, the amount of sewage discharge has increased year by year, making the situation of poor groundwater and pollution in my country more and more severe. Then, rational development, improvement of utilization efficiency and optimization of groundwater quality will become particularly important for the green and sustainable development of my country's ecological economy. Among them, the long-term scientific monitoring and chemical analysis of groundwater is an essential basis for realizing this goal. [0003] At present, my country's emphas...
