The invention relates to the technical field of cable installation, in particular to a submarine cable protection device and method. The submarine cable protection device comprises a connecting seat, a buffer mechanism and a shell, the shell is provided with an inner cavity, a cable is installed in the inner cavity of the shell, and the buffer mechanism is connected between the shell and the connecting seat; the buffering mechanism is of a quadrilateral structure, the shell and the connecting base are two opposite sides of the quadrilateral structure, a first elastic unit and a second elastic unit are arranged in the quadrilateral structure, and the two ends of the second elastic unit are connected with the shell and the connecting base respectively. The two ends of the first elastic unit are connected with the connecting base and the adjacent side respectively. By means of the cable protection device, on one hand, shaking of the cable is reduced, on the other hand, wind force borne by the cable is unloaded,
