River bottom tunnel water seepage detection device

The utility model discloses a water seepage detection device for a river bottom tunnel. The water seepage detection device comprises a guide rail, the inner side of the guide rail is slidably connected with a driving mechanism, the bottom of the driving mechanism is fixedly provided with a case, the right side in the case is fixedly provided with a control module, the left side in the case is fixedly provided with a wireless information transmission module, and the bottom of the case is provided with a thermal imaging camera. By adopting the structure and arranging the driving mechanism, during use, the double-shaft motor in the groove in the sliding block can drive the driving wheel to rotate, and the driving wheel is in fit connection with the inner wall of the lower end in the guide rail, so that the whole sliding block is driven to slide in the guide rail, and the thermal imaging camera and the sensing mechanism are moved; therefore, in the using process, the device can repeatedly move in the tunnel along
