The present invention relates to an intelligent manhole cover special for an electric power tunnel. The intelligent manhole cover comprises a cylindrical base at an opening of a manhole and a cover plate mounted at the top end of the base to seal the base. Internal threads are formed in the inner wall of the top of the base, while an external thread mounting portion matching with the internal threads is disposed at the central position of the bottom of the cover plate. A sunk groove is formed in the top end face of the base, and a first pressure sensor is mounted in the sunk groove. A plurality of support lugs are annularly disposed along the periphery of the inner wall of the bottom of the base at intervals; an inner supporting plate is placed on the support lug, and a second pressure sensor is mounted between each support lug and the inner supporting plate. Environment monitoring sensors and a light sensing probe are also mounted on the inner wall of the base. The intelligent manhole cover also comprises a controller and an alarm device. Signal output ends of the various sensors, the signal output end of the light sensing probe and the control input end of the alarm device are all electrically connected to the controller. The intelligent manhole cover special for an electric power tunnel is simple in structure, convenient to implement, high in intelligent level, and good in protection effect, and is integrated with a plurality of monitoring and protection functions.
