Device for simulating water quality salinization vertical variation rule of strand plain reservoir

The utility model discloses a device for simulating a water quality salinization vertical variation rule of a strand plain reservoir. The device comprises an earth pillar 3, wherein a water inlet 2 and a water draining opening 6 are formed in the side wall at the upper part of the earth pillar 3; the water inlet 2 is connected with a water supply container 1 for reservoir water or transferred water through a pipeline; the water draining opening 6 is connected with a overflow water catchment container 7 through a pipeline; an underground salt water inlet 9 is formed in the bottom of the earth pillar 3, and is connected with an underground salt water fixed waterhead water supply container 10 through a pipeline; a sampling opening 8 is formed in the side wall of the earth pillar. The device provided by the utility model can simulate the water quality salinization vertical variation rule of the strand plain reservoir under the influences of different influencing factors such as superficial layer underground salt water, bottom matter salinity release, the integrated function of the transferred water and the reservoir water, and the disturbance of wind, and further can be used for studying a hydrogeochemistry effect of underground salt water upward movement and a fresh water-salt water interface upward movement rule through changing different experimental conditions such as the quality of stored water in the pillar and the salt water buried depth.
