The invention discloses an online
water pollution monitoring device with a self-cleaning function, and belongs to the technical field of
water environment monitoring equipment, the online
water pollution monitoring device comprises a
floating platform, a plurality of floating bodies are connected to the
peripheral side of the bottom of the
floating platform in a surrounding manner, an equipment box is mounted at the bottom of the
floating platform, a protective mesh
enclosure is connected to the bottom of the equipment box, and a water suction pump is mounted in the equipment box. According to the device, water bodies with corresponding depths are extracted through liquid inlet nozzles with different depths, the water bodies are fed into a detection box, the
water body environment is monitored through a detection probe, after the probe is used,
distilled water obtained through condensation of a condensation box can be extracted through a water suction pump, and after the
distilled water is fed into an inner flushing mechanism, liquid spraying flushing can be conducted on the multiple detection probes;
algae in water are prevented from adhering to the surface of the probe through flushing of
distilled water, the detection precision is improved, meanwhile, the scraping and sweeping mechanism moves to scrape the
algae adhering to the outer side of the protective net cover, and
water pumping is prevented from being affected.
