[0007] Preferably, the adjusting mechanism includes a handle, the handle is rotatably connected to the jar body by a sealing bearing, the inner wall of the handle is threadedly connected to a second bolt, the lower end of the handle is fixedly connected to a threaded rod, the outer walls of the threaded rod are rotatably connected to the jar body by sealing bearings, the outer wall of the threaded rod is threadedly connected to a cross block, the inner wall of the cross block is slidably connected to a rod body, and the both ends of the rod body are fixedly connected to the jar body.

[0008] Preferably, the inner wall of the horizontal block is rotatably connected to multiple rollers via bearings, the outer walls of the multiple rollers are all in contact with the tank body, and a vertical rod is fixedly connected to the lower end of the horizontal block.

[0009] Preferably, the closure mechanism includes an electric telescopic rod, the bottom end of which is fixedly connected to the column, the output end of which is fixedly connected to the horizontal plate, both ends of which are fixedly connected to the curved plate, the outer walls of which are fitted to the column through sealing rings, and the inner walls of which are slidably connected to the support plate.

[0011] Preferably, the inner wall of the block is threadedly connected to the first bolt, and the end of the first bolt is pressed against the sampling tube.

[0012] The water sampling device proposed in this utility model has the following advantages: by adjusting the mechanism and the tank, the handle drives the threaded rod to rotate, the threaded rod drives the horizontal block to move downward, the horizontal block drives the vertical rod to move downward, the vertical rod drives the column to move downward, and thus drives the two sampling test tubes to move downward. In this way, workers do not need to bend over to adjust the depth of the sampling test tubes in the river water, thereby increasing the practicality of the work.

[0013] Through the cooperation of the sealing mechanism and the column, the electric telescopic rod retracts, causing the horizontal plate to move downward. The horizontal plate then causes the two curved plates to move downward, which in turn causes the connecting rod to move. The downward movement of the connecting rod causes the sealing plug to move downward. The outer wall of the sealing plug contacts the sampling test tube, thus sealing the upper end of the sampling test tube. In this way, the mouth of the sampling test tube is sealed, preventing the river water after sampling from flowing out of the sampling test tube and affecting the quality of river water collection, thereby improving the quality of work.
