[0031] The principle of this utility model is:

[0032] When the utility model is in use, it is connected in parallel to the water inlet pipe of the sewage treatment plant. The raw water entering the plant flows into the device from the raw water inlet 12, and then returns to the water inlet pipe through the raw water outlet 13. In this process, the raw water enters the interior of the filter screen cylinder 6 after being filtered by the filter cloth on the filter screen cylinder 6. When sampling is required, the valve on the pipe connected to the clean water outlet 14 can be opened. During actual sampling, the water flow can be allowed to flow for a while to release the water stored in the filter screen cylinder 6, thereby improving the timeliness of sampling.

[0033] During the operation of the device, in order to ensure the stability of operation, the cleaning device 5 is driven by the motor 4 to clean the filter cloth coated on the surface of the filter cylinder 6, thereby effectively avoiding sludge accumulation, causing the filter cloth filtering efficiency to deteriorate, and affecting the sampling.

[0034] The filter cloth is not shown in the accompanying drawings of the embodiment, but it should be easy for those skilled in the art to understand that when the filter cloth is coated, its joint is gathered in the pressure groove 612 and then fixed by the pressure strip 62, and its two ends are pressed and fixed by the pressure cover plate 63 at the upper end and the lower end is pressed and fixed by the mounting groove 15 after being gathered, so as to avoid liquid leakage and ensure stable sampling. The lower end of the connecting shaft 53 in the rotating frame 51 is rotatably connected to the bearing 632 in the pressure cover plate 63, which effectively avoids deflection and further ensures the stability of the filter cylinder 6 and the rotating frame 51 during use.
