Abstract

An underwater device includes a main body and a center of gravity mechanism. The center of gravity mechanism is disposed in the main body. The center of gravity mechanism includes a fixing plate, a bracket, a first driving motor, two guiding rods, two linear bearings, a battery module and a transmission assembly. The bracket is fixed to the fixing plate. The first driving motor is disposed on the bracket. The two guiding rods are fixed at two sides of the fixing plate. The two linear bearings are disposed on the two guiding rods. The battery module is connected to the two linear bearings. The transmission assembly is connected to the first driving motor and the battery module. The first driving motor drives the battery module to move along the two guiding rods through the transmission assembly to shift a center of gravity of the underwater device.
