Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1 , the embodiments of the present utility model include:

[0018] like Figure 1 The automatic river water quality monitoring station shown includes: a float 1, a fixed plate 6, a water quality sensor 3, a controller 2, a water pump 12, a sampling tube 4, a gantry 8, an anchor 7 and a pull rope 16. The fixed plate 6 is horizontally arranged on the float 1. The float 1 adopts an annular hollow tube. The annular hollow tube has large buoyancy and good stability when floating on the water surface.

[0019] The fixing plate 6 is provided with U-bolts 15 connected to the buoy 1, providing a stable structure. A pull rope 16 is connected between the anchor 7 and the buoy 1. The anchor 7 is a cement anchor and is sunk to the bottom of the water.

[0021] The sampling tube 4 is vertically mounted on a fixed plate 6 and positioned below a gantry 8. The water quality sensor 3 is positioned within the gantry 8 and extends downward into the sampling tube 4 to monitor the water quality of the river water in the sampling tube 4. The fixed plate 6 is provided with a drain hole 5 below the sampling tube 4. In this embodiment, the drain hole 5 has a diameter no greater than 3 mm, allowing the river water in the sampling tube 4 to slowly flow out through the drain hole 5, keeping the water quality sensor 3 dry and reducing the adhesion of microorganisms.

[0022] A water pump 12 is set on the fixed plate 6. The water inlet end of the water pump 12 is provided with a water inlet pipe 11 extending to the bottom of the float 1. The water outlet end of the water pump 12 is provided with a sampling water pipe 13 extending to the sampling cylinder 4. The river water can be pumped into the sampling cylinder 4 for timed automatic sampling.
