Description

Two-phase sampling device suitable for river, lake and reservoir Technical Field The utility model belongs to the field of sampling devices, and particularly relates to a two-phase sampling device suitable for a river, a lake and a reservoir. Background In the environment monitoring category, aiming at water quality monitoring and sediment monitoring carried out by river, lake and reservoir, a core technical means for evaluating the health state of water body is formed. The water quality monitoring can accurately analyze the pollution degree of the river, lake and reservoir, and the sediment monitoring effectively backtracks the long-term accumulation process of the water pollution through quantitative analysis of pollutants such as heavy metals in the sediment, thereby realizing the accurate backtracking of potential pollution sources. In terms of the sampling flow, water quality sampling and sediment sampling are usually performed by means of mutually independent sampling equipment. Taking the water sampler and the sediment sampler which are widely used at present as examples, the water sampler and the sediment sampler belong to sampling instruments with independent functions. Even if the two types of sampling devices can be simply integrated, the carrying convenience is improved, however, in actual sampling operation, the two types of sampling devices still need to independently carry out sampling operation, and disposable sampling of the water body and the bottom mud cannot be realized.
