The sampling device for detecting nitrogen and phosphorus pollution in water environment sediments comprises: a base 1, on which a hoisting device and a sampling device are arranged;

[0026] The hoisting device includes a fixed column 2, a mounting column 3, a boom 4, two pulleys 5, a self-locking hand winch 6 and a hoisting rope 7, wherein the fixed column 2 is fixedly mounted on the base 1, the mounting column 3 is rotatably mounted on the top of the fixed column 2, the boom 4 is fixedly mounted on the mounting column 3, the two pulleys 5 are both rotatably mounted on the boom 4, the self-locking hand winch 6 is fixedly mounted on a side surface of the mounting column 3, and the hoisting rope 7 is wound around the self-locking hand winch 6;

[0027] The sampling device includes a sampling box 8, a cylinder 9, a top column 10, a connecting column 11, a suction cup 12, a sampling tube 13 and a soft brush 14. The sampling box 8 is fixedly installed at one end of the suspension rope 7, the cylinder 9 is fixedly installed in the sampling box 8, the top column 10 is fixedly connected to the output end of the cylinder 9, the connecting column 11 is threadedly connected to the bottom end of the top column 10, the suction cup 12 is fixedly connected to the bottom surface of the connecting column 11, the sampling tube 13 is fixedly connected to the suction cup 12, and the soft brush 14 is snap-connected to the bottom end of the sampling tube 13.

[0028] like Figure 4 As shown, a fixing frame 15 is fixedly connected to the other side surface of the mounting column 3, a rotating handle 16 is hingedly connected to the inner side of the fixing frame 15, a square block 17 is fixedly connected to the middle end of the rotating handle 16, and two clamping blocks 18 are fixedly connected to the outer surface of the sampling box 8;

[0029] By setting the rotating handle 16, the boom 4 can be rotated horizontally to facilitate the collection of samples.

[0030] like Figure 3 As shown, a guide tube is also provided at the bottom end of the sampling box 8, and the guide tube is adapted to the sampling tube 13;

[0031] The provision of the guide tube can help to stably maintain the vertical direction of the sampling tube 13 when the cylinder 9 pushes out the sampling tube 13 and inserts it into the bottom sediment, thereby facilitating the collection of qualified sediment samples.

[0032] like Figure 3 As shown, the hanging rope 7 is located at the center of the top surface of the sampling box 8, and the center of gravity of the sampling box 8 is lower.

[0033] The arrangement of the center of gravity of the sampling box 8 being biased downward is conducive to keeping the sampling port of the sampling tube 13 always facing downward.

[0034] like Figure 3 As shown, the sampling tube 13 is in a conical shape, and the sampling tube 13, the suction cup 12, the connecting column 11, the top column 10 and the cylinder 9 are located on the same vertical center line;

[0038] The working principle of the sampling device for detecting nitrogen and phosphorus pollution in water environment sediments provided by the utility model is as follows:

[0039] Step 1: When sampling of the bottom sediment in the center of the river is required, the device is first installed on the boat, and then the sampling tube 13 is threadedly installed on the top column 10 through the connecting column 11, the boom 4 is rotated to the water surface by turning the handle 16, and then the handle 16 is turned down to engage with the block 18, and then the clamping plate is put in to limit the boom 4 on the block 18;

[0040] The second step: then turn the self-locking hand-cranked winch 6 to slowly put the sampling box 8 into the water. When the sampling box 8 touches the river bottom, start the cylinder 9 to push out the sampling tube 13, collect the sediment into the sampling tube 13, and then start the cylinder 9 for the return stroke. Under the simultaneous action of the conical sampling tube 13 and the soft brush 14, sediments of different densities can be collected. Then reverse the self-locking hand-cranked winch 6 to lift the sampling box 8 out of the water, rotate the boom 4 again through the turning handle 16, rotate and remove the sampling tube 13, and complete the sampling of the bottom sediment.
