[0026] The water blocking device includes a water blocking plate 13, one side of the water blocking plate 13 is fixedly connected to one end of the movable column 10, one side of the water blocking plate 13 is fixedly connected to a sealing plate 14, and one side of the water blocking plate 13 is connected to a bolt 16 through a threaded sleeve. There are multiple water blocking devices, and the multiple water blocking devices are respectively arranged at the upper, middle and lower parts of the sampling tube 1, so that water can be taken from the upper, middle and lower layers of different depths.

[0027] The outer wall of the sampling tube 1 is provided with a threaded surface 2, and the threaded pipe 4 is threadedly connected to the threaded surface 2. Through the threaded connection between the threaded pipe 4 and the threaded surface 2, the water collecting pipe 3 is installed at the bottom of the sampling tube 1. Then, when water enters the interior of the sampling tube 1, the water will enter the interior of the water collecting pipe 3 for storage. The water inside the water collecting pipe 3 is the water to be monitored and sampled.

[0028] The top of the movable plate 5 passes through the channel 7 and extends to the outside of the sampling tube 1, and the outer wall of the movable plate 5 is slidably connected to the inner wall of the channel 7, so that the movable plate 5 can be controlled to move inside the sampling tube 1 through the outside of the sampling tube 1.

[0029] A handle 6 is fixedly connected to the top of the movable plate 5 , and the movable plate 5 can be driven to move by the handle 6 .

[0030] One end of the spring 12 is fixedly connected to one end of the telescopic column 8, and the telescopic column 8 is slidably connected to the slide groove 11. When the telescopic column 8 is subjected to a large force, the spring 12 will be squeezed, so that the spring 12 is in a compressed state, and the telescopic column 8 can move into the inside of the slide groove 11.

[0031] A screw groove 15 is provided on the outer wall of the sampling tube 1, and one end of the bolt 16 is threadedly connected to the screw groove 15.
