The utility model belongs to the technical field of marine environment monitoring equipment, and provides a sampling device for
seawater detection and analysis, which comprises a cylinder main body with a built-in cavity, an overflow port communicated with the cavity of the cylinder main body is arranged at the top of the cylinder main body, and a liquid inlet and a liquid extraction port communicated with the cavity of the cylinder main body are arranged at the bottom of the cylinder main body; a liquid inlet
pipe which is communicated with the liquid inlet and extends into the cavity of the
barrel main body is arranged at the liquid inlet, a liquid extraction
pipe which is communicated with the liquid extraction opening and extends into the cavity of the
barrel main body is arranged at the liquid extraction opening, a liquid inlet hole penetrating through the side wall of the liquid inlet
pipe is formed in the liquid inlet pipe, and a liquid extraction hole penetrating through the side wall of the liquid extraction pipe is formed in the liquid extraction pipe; the height of the liquid pumping hole in the axial direction is larger than that of the liquid inlet hole in the axial direction. The sampling device for
seawater detection and analysis is simple in structure and convenient to use, impurities such as floating objects and
silt in
seawater sampling are reduced, detection and analysis of seawater samples are facilitated, and the sampling and analysis efficiency is improved.
