The invention relates to an intelligent antitheft safe municipal road well lid comprising a lid body, a lifting portion and a control processor. The lifting portion comprises a fixing portion matched with the lid body and is annular. An annular groove is formed in the fixing portion. A plurality of lifting shafts are arranged in the annular groove. The tops of the lifting shafts are connected with the lid body. The height of the annular groove is lower than the lifting portion. When the lifting shafts are located at the initial positions, the upper surface of the lid body and the lifting portion are in the same horizontal plane. The lifting shafts are connected with the control processor. The control processor outputs ascent signals or descent signals to the lifting shafts. The lifting shafts ascend or descend according to the ascent signals or the descent signals. A cavity is formed in the lid body. A balance detection device is arranged in the cavity. The balance detection device is connected with the control processor and used for detecting the balance degree of the well lid.
