| titleOfInvention | Groundwater sample collection filter device |
| abstract | The utility model discloses a groundwater sample collecting and filtering device, comprising an extraction mechanism, a water pumping hose and a filter. An inner threaded pipe is adhered to the inner wall of the water pumping hose, and the filter comprises an upper spherical shell and a lower spherical shell which are clamped to each other. A spherical shell, a filter cotton filled between the upper spherical shell and the lower spherical shell, an upper external threaded pipe connected to one end of the upper spherical shell, and a lower externally threaded pipe connected to one end of the lower spherical shell. The outer wall of the shell is provided with water inlet holes distributed at equal distances, and the upper spherical shell and the lower spherical shell form a hollow spherical structure. The utility model can repeat the steps of extracting the air inside the water pumping hose and discharging the air, and the water body is drawn into the cylinder. Filter large particles of impurities and sediment in the water to avoid clogging of the sampling device, and can be disassembled and cleaned to prolong the service life of the sampling device. |
