Portable underground water sampler

Abstract

The invention provides a portable underground water sampler which is installed in a vinyl plastic outer shell. A miniature pump groove, a battery jar, a switch groove and a wire groove are arranged inside the vinyl plastic outer shell. A miniature pump is installed in the miniature pump groove, wherein an air inlet of the miniature pump is connected with a first opening of an underground water collecting device through a circular hole of the vinyl plastic outer shell, and a second opening of the underground water collecting device is connected to a water inlet flexible pipe; a battery is installed in the battery jar; a switch is installed in the switch groove; the battery is connected with the switch and the miniature pump in series respectively through wires arranged in the wire groove to form a complete closed loop; the vinyl plastic outer shell is composed of two parts, wherein internal structures of the two parts correspond to each other, the two parts are fastened through screws after being buckled, and therefore all components inside the vinyl plastic outer shell are fixed. The portable underground water sampler has the advantages of being low in energy consumption, tiny in perturbance and easy to carry, thereby having great superiority in underground water collecting work under the conditions that a site has no water pumping facility or does no have approach conditions for large water pumping equipment, a large number of samples are needed, and energy supply is not sufficient.

Description

technical field [0001] The invention relates to the field of groundwater environmental protection, in particular to a groundwater sampling device. technical background [0002] Traditional groundwater sampling is generally divided into two types: fixed pumping devices and mobile pumping devices. These two types of groundwater sampling devices are suitable for situations where external power supply is convenient, the voltage is high, and the amount of water pumped is large. Moreover, there are still the following problems in specific use: due to its large size, its storage, transportation, maintenance, and operation are extremely inconvenient; for inconvenient field transportation, difficult to achieve external power supply, and many groundwater sample collection points, the pump is used in large areas. When the flow is working, it will disturb the groundwater flow field, destroy the original pollutant concentration distribution in the groundwater, and the investigation resul...

Moreover, there are still the following problems in specific use: due to its large size, its storage, transportation, maintenance, and operation are extremely inconvenient; for inconvenient field transportation, difficult to achieve external power supply, and many groundwater sample collection points, the pump is used in large areas. When the flow rate is working, it will disturb the groundwater flow field, destroy the original pollutant concentration distribution in the groundwater, and the investigation results of groundwater pollutants will deviate from the actual
