A filter plate 502 is placed inside the collecting box 501. The solid-liquid mixture is filtered through the filter plate 502, which is convenient for detecting solids and effectively realizing the separate detection of particles and liquid in wastewater, thereby effectively improving the accuracy of wastewater detection. The top of the filter plate 502 is fixedly connected to the handle 503, and the handle 503 is arranged to facilitate the picking operation of the filter plate 502.

The detection cylinder 601 is fixed to the top of the mounting base 1, the bottom of the mounting base 1 is fixed to the motor 602, the output end of the motor 602 passes through the mounting base 1 and is fixedly connected to the base plate 610 arranged above the mounting base 1, the top of the base plate 610 is fixedly connected to the spoiler 604, and the spoiler 604 is provided with a stirring piece 60 5. The detection liquid flows into the interior of the detection cylinder 601 through the liquid discharge pipe 406, and the detection probe 8 can detect the wastewater liquid. When cleaning is required, the detection cylinder 601 is injected with clean water through the branch pipe 608. The stirring piece 605 arranged on the surface of the spoiler block 604 is driven by the motor 602 to rotate to clean the inside of the detection cylinder 601. The top of the base plate 610 is located at the periphery of the spoiler block 604 and is fixedly connected with the spoiler piece 606. The setting of the spoiler piece 606 can increase the spoiler effect, improve the cleaning effect of the inside of the detection cylinder 601, and reduce the detection error.

[0047] like Figure 9-11 As shown, the top of the detection cylinder 601 is fixed to the sealing cover 609 by bolts, the liquid inlet pipe 607 is connected to the cleaning device 7 arranged inside the detection cylinder 601, and the cleaning device 7 can clean the detection probe 8.

[0049] like Fig.11As shown, the cleaning device 7 includes an annular base 701, a swivel 702 and a cleaning nozzle 703. The interior of the annular base 701 is a cavity. The annular base 701 is connected to the liquid inlet pipe 607. The water injected by the liquid inlet pipe 607 can be injected into the interior of the swivel 702 through the annular base 701. The side of the annular base 701 is connected to the swivel 702 with a cavity inside through a sealed bearing. A cleaning nozzle 703 is installed on the swivel 702.

[0050] like Fig.11 As shown, the cleaning nozzle 703 is tilted, and the nozzle of the cleaning nozzle 703 points at an angle of 45 degrees to the horizontal plane.

The air pump 301 is connected with the buoyancy cylinder 303 through the spring tube 302. The air pump 301 can be used to perform air intake and exhaust operations inside the buoyancy cylinder 303. When air is taken in, the buoyancy cylinder 303 rises in the water body due to the buoyancy force, and the input pipe 206 rises in the water body. When the air pump 301 is exhausted, the buoyancy cylinder 303 enters the liquid through the bottom outlet hole 307 at the bottom, and the buoyancy cylinder 303 descends, realizing the downward movement of the input pipe 206 in the water body, which is convenient for the input pipe 206 to extract water from different water layers. The water inside the input pipe 206 enters the separation device 4 through the extraction, and the separation hole 40 4 can separate solid particles and liquids. The interior of the separation cylinder 403 is pressurized by the water delivery pump 207. The separated solid particles can be discharged into the interior of the collection and detection device 5 by opening the solenoid valve on the solid discharge pipe 405. The detection liquid flows into the interior of the detection cylinder 601 through the liquid discharge pipe 406. The detection probe 8 can detect the wastewater liquid. When cleaning is required, clean water is injected into the detection cylinder 601 through the branch pipe 608. The stirring piece 605 arranged on the surface of the spoiler block 604 is driven by the motor 602 to rotate to clean the interior of the detection cylinder 601. The cleaning nozzle 703 is tilted to realize the function of rotating the cleaning nozzle 703 around the annular base 701 through the reaction force of the water flow during the spray cleaning process, thereby realizing the all-round cleaning operation of the detection probe 8.
