The sampling module includes a submersible pump 22, and the submersible pump 22 draws sampled water up from the sampling point and delivers the sampled water to the inlet quick connector 19 of the housing 14 through a hose 23 connected to the submersible pump 22. The water inlet quick connector 19 sequentially passes through the water inlet electromagnetic valve 24 and the one-way valve 25 through the hose, and finally enters the detection module through the adjustable quick connector 4 (a multi-way structure is required to be installed at the position of the adjustable quick connector 4 and is used for independently connecting the hose, so that each water sample independently enters the detection container).
It should be noted that, the mode that the water sample got into detection module from detection module bottom, whole water inlet process can not produce the splash, and the surface of water is comparatively steady to rise. And the whole water inlet pipeline is controlled to be switched on and switched off by the water inlet electromagnetic valve 24, and the one-way flow of the water body is controlled by the one-way valve 25, so that the advantage that the water sample does not flow back when the water channel is switched off is achieved, and the filling time of water flow vacancy in the water pipe caused by filling back flow is further shortened.
