Large eccentric rotary displacement device

The invention belongs to the technical field of equipment installation, and provides a large eccentric rotary displacement device which is used for eccentrically clamping a water chamber end socket and comprises a clamp mechanism and a turnover mechanism, the clamp mechanism is installed on the turnover mechanism, and the turnover mechanism drives the clamp mechanism to be turned over and switched in the horizontal direction and the vertical direction; the clamp mechanism comprises a rotating platform, a clamping part and a counterweight part; the rotating platform is connected with a rotating shaft of the turnover mechanism, the clamping parts are circumferentially distributed on the surface of the rotating platform, and a circle defined by the circumferential distribution of the clamping parts and the rotating platform are eccentrically arranged. The clamp mechanism is installed on the turnover mechanism, the turnover mechanism can drive the clamp mechanism to turn over in the horizontal direction and the v
