Zusammenfassung: | The utility model belongs to the technical field of environmental DNA (deoxyribonucleic acid) sampling, and particularly relates to a sampling device applied to a flowing water area, which comprises a sampling bottle, a sampling tube, a sampling tube and a sampling tube, the water inlet tank is detachably mounted in the sampling cavity; the sampling opening is formed in the side wall of the water inlet groove so as to communicate the inlet with the sampling cavity; the pressure switch is located in the water inlet groove; wherein the pressure switch moves up and down along the water inlet groove along with the change of water depth so as to connect or disconnect the sampling port and the inlet. The sampling port and the inlet are connected or disconnected by the pressure switch through the water pressure of the deep water layer, so that the problem of inaccurate sampling water depth caused by deviation of the sampling bottle due to the influence of water flow in a water area with relatively high flowability i |
