An anti-clogging urban underground drainage pump related to the technical field of drainage pump sewerage, comprises a base plate and a tube body; the top side of the base plate is provided with a motor fixed by bolts, and the tube body is provided at the output end of the motor with a liquid inlet on one side; and fixed columns are evenly fixed at one side of the liquid inlet by spot welding, and a vibration mechanism is fixed at one end of fixed columns by spot welding. The invention is driven by the rotation of the impeller in the tube body through the rotation of the motor, to make the water flow with foreign matter from the liquid inlet into the baffle plate; the sealing curved plate attached to one side of the baffle plate starts to slide on the inner wall of the tube, to make the originally sealed liquid flow spout open; the supporting columns will push out the foreign matter clogged in the liquid flow spout, and the foreign matter on the baffle plate will be driven by the water flow into the drainage tank connected to the liquid flow spout on the one side, to avoid the foreign matter from contacting with the impeller under the water flow and causing the whole impeller to be damaged by the foreign matter winding.
