Water source dispatching and shunting device with sewage interception function for reservoir dam

The invention relates to the technical field of reservoir dams, and discloses a water source dispatching and shunting device with a sewage interception function for a reservoir dam. Comprising a curved filtering structure which is placed in a water channel and located at the tail of a water channel gate, a spiral conveying structure which is installed at the rotor end of a driving motor and rotates along with the rotor end of the driving motor, and an elastic compaction structure which is elastically installed at a sundry discharging port of the curved filtering structure. The water source dispatching and shunting device with the dirt interception function for the reservoir dam is installed at the tail of a gate, sundries can enter a conveying part in a concentrated mode under the action of water flow pressure, so that the phenomenon that the sundries block filtering holes is reduced, the device can rotate by 180 degrees, the entering port and the discharging port of the filtering holes are reversed, and the
