Test device for automatically predicting water inflow of subsea tunnel

The utility model discloses a test device for automatically predicting the water inflow of a subsea tunnel, relates to the field of test equipment for predicting the water inflow, and provides the following scheme aiming at the problems that the conventional test device for predicting the water inflow of the subsea tunnel is poor in test accuracy, cannot complete automatic prediction, needs high labor intensity and is poor in test effect. The device comprises a collecting cover frame used for collecting gushing water, a connecting structure used for guiding flow is installed at the bottom end of the collecting cover frame, a water collecting structure used for temporarily storing the gushing water is arranged in the middle of the connecting structure, and a containing box used for containing experimental wastewater is installed on the side, away from the collecting cover frame, of the connecting structure. A water pump used for circulating prediction is arranged on the inner side of the water collecting struc
