1. A device for measuring levelness of a top cover of a reactor pressure vessel, the device comprising:
a mounting and fixing mechanism comprising a mounting bottom plate, and a fixing mechanism disposed on the mounting bottom plate, wherein the fixing mechanism is configured to be fixed to a lower end face of the top cover;
an inclination sensor mounting base comprising a bearing plate and a portal frame disposed on the bearing plate, wherein the bearing plate is disposed on the mounting bottom plate, and a top surface of the portal frame is attached to a sealing surface of the top cover; and
an inclination sensor mounted on a sensor mounting surface of the bearing plate and located in the portal frame, and configured to obtain levelness of the sealing surface of the top cover by measuring levelness of the sensor mounting surface of the bearing plate, wherein the sensor mounting surface of the bearing plate is parallel to the sealing surface of the top cover.
