The counterweight 1 sinks to the bottom of the sewage, and the floating plate 4 floats to the top of the sewage. The sleeve box 3 is located in the middle position between the floating plate 4 and the counterweight 1 under the elastic force of the first spring 5, thereby ensuring that the sampling is located in the water layer of the sewage, avoiding a large amount of floating scum and sediment in the sampling due to the sampling device being too high or too low, and ensuring the reliability of the water layer sampling work of the sewage.

[0021] In this embodiment, the bottom end of the sliding rod 2 is installed on the top of the counterweight 1 through bolts.

The counterweight 1 sinks to the bottom of the sewage, and the floating plate 4 floats to the top of the sewage. The sleeve box 3 is located in the middle position between the floating plate 4 and the counterweight 1 under the elastic force of the first spring 5, thus ensuring that the sampling is in the water layer of the sewage, avoiding a large amount of floating scum and sediment in the sampling due to the sampling equipment being too high or too low, and ensuring that the sampling point is in the middle water layer. Turn off the electromagnet 15, and the second spring 16 pushes the clamping plate 14. The clamping plate 14 clamps on the outer side of the sliding rod 2, thus fixing the sleeve box 3 on the sliding rod 2 to prevent the sleeve box 3 from moving during sampling. First, turn on the motor 7 in the forward direction. The motor 7 drives the rotating blade 8 to rotate, and pushes the water inside the inner cavity 6 out from the left side of the sleeve box 3. Then, after the sewage passes through the filter screen 10, it enters the right end of the inner cavity 6 through the conduit 9 and the first one-way valve 11, and is pushed to the left by the rotating blade 8, effectively cleaning the floating scum adhered to the conduit 9, the connecting pipe 12 and the left side of the sleeve box 3 near the inner cavity 6.
