Abstract: The invention discloses a power generating device and an operation method thereof based on ocean temperature difference, which belong to the field of ocean energy utilization, and include a negative thermal expansion body, a rope and a generator. The negative thermal expansion body is connected to the rope, and the rope is connected to the generator simultaneously. The negative thermal expansion body is in a contracted state when in the hotter upper seawater close to the sea surface, and the difference obtained by deducting buoyancy from gravity is relatively large. The negative thermal expansion body is in an expanded state when in colder deep seawater, and the difference obtained by deducting buoyancy from gravity is relatively small. The unbalanced force on the rope will drive the rope to move, and the generator will be driven to generate power through the rope.
