Underground organic pollutant rapid sampling device

The invention discloses an underground organic pollutant rapid sampling device, which comprises a drill bit, a drill cylinder, and an inner tube. The inner tube is located in the drill cylinder. The bottom of the drill cylinder is provided with a rotating flywheel. The bottom end of the inner tube is located on the rotating flywheel. A sample chamber is provided inside the side wall of the inner tube, and the opening thereof faces the inner wall of the drill cylinder. A sampling port is provided on the inner wall of the drill cylinder. The sample chamber is provided with an inlet tube and an outlet tube which are communicated to the outside. When the inner tube is rotated so as to overlap the opening of the sample chamber and the sampling port on the inner wall of the drill cylinder, underground organic pollutants enter the sample chamber and are exported through the outlet tube to be sampled and detected. The device is capable of sampling volatile organic pollutants in underground soil gas and groundwater. 本
