Abstract: A marine information integrated online monitoring buoy system comprises a buoy body. Specifically, a protection apparatus is disposed outside the buoy body. A bearing is disposed outside the buoy body, convex strips are arranged around a bearing outer ring, two floating rings are disposed outside the bearing outer ring with a certain spacing distance from the outer ring and arranged vertically, a protective cylinder is arranged between the upper and lower floating rings in a surrounding manner and is rotatable relative to the floating rings, and then a protective retaining ring is sleeved outside the protective cylinder and is rotatable relative to the protective cylinder. The longest end of a protective retainer is abutted against the bearing outer ring during rotation of the outer side of the protective retaining ring, and a friction block is disposed on the protective retainer.
