Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 3A sewage pollutant sampling device comprises a sampling barrel 1, a waterproof motor 14 is fixedly arranged on the top of the sampling barrel 1, a first water inlet hole is evenly opened at the bottom of the sampling barrel 1, an output end of the waterproof motor 14 passes through the top of the sampling barrel 1 and is connected to a connecting rod 15, a rotating disk 16 is fixedly arranged at the bottom of the connecting rod 15, a second water inlet hole is evenly opened at the bottom of the rotating disk 16, a sealing gasket 17 is fixedly arranged at the bottom of the rotating disk 16, the first water inlet hole at the bottom of the sampling barrel 1 is closed by the sealing gasket 17, and the connecting rod 15 is driven to rotate by the waterproof motor 14 , the turntable 16 and the sealing gasket 17 are driven to rotate by the connecting rod 15. When the second water inlet hole on the turntable 16 is aligned with the first water inlet hole at the bottom of the sampling bucket 1, the external sewage will enter the sampling bucket 1 along the first water inlet hole and the second water inlet hole, and then the waterproof motor 14 drives the turntable 16 and the sealing gasket 17 to rotate. When the second water inlet hole at the bottom of the turntable 16 is offset from the first water inlet hole, the sealing gasket 17 will re-close the first water inlet hole, and the bottom of the sealing gasket 17 is in contact with the bottom of the inner wall of the sampling bucket 1, and the outer wall of the sampling bucket 1 is placed with a supporting assembly.

[0021] The supporting assembly includes a supporting foot 11, a screw 13 is fixedly provided at the bottom of the supporting foot 11, a counterweight 12 is placed at the bottom of the supporting foot 11, a threaded hole is opened at the top of the counterweight 12, the screw 13 is screwed into the threaded hole, and the total weight of four groups of counterweights 12 is greater than the weight of the waterproof motor 14. The counterweight 12 can make the sampling bucket 1 sink stably in the water and fall vertically on the bottom of the water, so that it can stably complete the sampling of underwater pollutants. The counterweight 12 is screwed and fixed to the bottom of the supporting foot 11 by the screw 13. Therefore, after the counterweight 12 is unscrewed, the counterweight 12 of different weights can be quickly replaced according to different water depths. The first water inlet hole at the bottom of the sampling bucket 1 corresponds to the second water inlet hole at the bottom of the turntable 16, and the supporting foot 11 is evenly fixed on the outer wall of the sampling bucket 1.
