Submersible drum direct current motor wave energy power generation device

A submerged cylinder direct current motor wave energy power generation device comprises a submerged cylinder, a vertical direct current motor, a horizontal direct current motor, a shot, a straight rod, a balance weight and a motor fixing rod, the vertical direction direct current motor converts a vertical direction component of sea surface wave water quality point movement into electric energy, and the horizontal direction direct current motor converts a horizontal direction component of sea surface wave water quality point movement into electric energy; one end of the motor fixing rod is fixed on the inner wall of the submersible cylinder, and the other end is connected with a stator of the DC motor; the rotor is in threaded connection with the straight rod and can rotate around the bolt; the shot is connected with the straight rod, inertia is transmitted to the mover by pushing the straight rod when the shot does inertial motion, and when the submersible cylinder does elliptic motion along with waves, the s
