The invention relates to intelligent municipal engineering road sewer cleaning equipment. The intelligent municipal engineering road sewer cleaning equipment comprises a lifting and locking device, wherein the lower end surface of the lifting and locking device is provided with an index dirt removal device, the index dirt removal device can realize the functions of automatically indexing sundries and efficiently crashing the sundries, the crashed sundry particles are automatically flushed away by virtue of sewage, the dredge effect is good, the risk of secondary blocking within a short time is avoided, and the sundries and sludge are prevented from being treated manually for a second time, so the working efficiency is high. The lifting and locking device comprises an upper lifting circular table, the middle of the lower end surface of the upper lifting circular table is provided with a lifting motor through a motor base, an output shaft of the lifting motor is provided with a lifting screw through a coupling, the bottom end of the lifting screw is installed on a lifting support plate through a bearing, and four No. 2 locating shafts are symmetrically welded between the lifting support plate and the lifting circular table. According to the equipment provided by the invention, the full-automatic dredging function of a sewer can be realized, and a novel full-automatic efficient approach for cleaning the sewer is provided.
