The invention discloses a
water quality monitoring device for
environmental engineering, which comprises a monitoring box, a U-shaped frame, a power-driven roller, a
rope, a fixed cylinder, a filter
barrel, a
water pumping hose and the like, the U-shaped frame is arranged at the bottom of the inner wall of the monitoring box, the roller is driven by a power mechanism, the bottom end of the
rope is connected with the filter
barrel, and the bottom end of the filter
barrel is connected with the
water pumping hose. The auxiliary mechanism controls the roller through a locking rod and a
ratchet wheel, so that stable
sedimentation of the filter barrel is ensured; the monitoring mechanism monitors
water quality parameters by using a
piston barrel and a detection probe; the cleaning mechanism automatically clears impurities on the surface of the filter vat to keep monitoring efficiency; the
water quality monitoring device is ingenious in design, high in
automation degree and easy and convenient to operate, the water
quality monitoring efficiency and accuracy are effectively improved, the maintenance cost is reduced, and the water
quality monitoring device is suitable for water
quality monitoring of various water environments such as rivers, lakes and seas.
