Water conservancy gate structure capable of discharging sludge and sundries

The utility model discloses a water conservancy gate structure capable of discharging sludge and sundries, and relates to the field of water conservancy projects. According to the scheme that impurities are smashed through a smashing cutter, filtering is conducted through a first filter screen and a second filter screen, and sludge and sundries are discharged through a sludge pump, the beneficial effects are that large sundries at the front end of a collecting frame are filtered through the first filter screen, a submersible motor drives the smashing cutter to smash the large sundries, and the sundries reach the position between the first filter screen and the second filter screen; a sludge pump is started to drive a recycling pipe, so that the recycling pipe drives the sludge and impurities in a collecting frame to reach a discharging pipe, the discharging pipe is placed on the inner wall of a lifting precipitation frame, so that the sludge and impurities in the discharging pipe reach the interior of the lif
