Abstract: A thermally-driven full-ocean-depth lens wiping device and a method. The device includes a wiper hingedly mounted on a housing, a shape memory alloy wire mounted on the housing and configured to connect and drive the wiper to perform a wiping motion, and a fixing component configured to position and arrange the shape memory alloy wire, and further includes the housing mounted on a full-ocean-depth lens and a waterproof connector electrically connected to the shape memory alloy wire; in the method, the shape memory alloy wire is electrically heated to be extended and contracted, thereby pulling the wiper to rotate, and wiping of the lens is completed.
