Automatic water pumping device for optical cable well

The utility model discloses an automatic pumping device for an optical cable well, which relates to the technical field of building equipment and comprises a supporting device, a buoyancy device is movably connected to the lower end in the supporting device, and an adjusting device is arranged at the front end in the supporting device. A buoyancy plate, a first limiting block, a first sliding hole, a limiting column, a limiting groove and a square hole are arranged to drive an electric connection sleeve to move upwards, after the electric connection sleeve moves to a preset position, a first electric wire and a second electric wire can be communicated through the electric connection sleeve and a power strip to supply power to a water pump, and then water in an optical cable well can be pumped through a water suction pipe; and meanwhile, the pumped water is discharged out of the optical cable well through a discharge pipe, so that the problems that most existing optical cable well water pumping devices are not
