The device can buffer collision between the ship and the wharf, other ships or dock, and lighten the collision force. 2. Gangway ladder bumper: a gangway bumper is mounted on the ship gangway to protect the gangway from impact and wear. It is a cushion-like device, typically made of rubber. 3. The fender cable anticollision ware: the beam bumper is used to protect the vessel mooring lines from damage. It is typically made of rubber and is looped around the lines to cushion the impact between the vessel and the lines. 4. Cruise collision avoidance system: cruise collision avoidance systems are an integrated electronic device that monitors obstacles and other vessels around a vessel and provides early warning and navigation advice to prevent collisions from occurring. These systems typically include radar, GPS, and infrared sensors, among others.

The existing ship cruising anti-collision system is mainly an electronic device, and anti-collision protection of ship navigation is failed when the electronic device fails, so that a novel ship anti-collision with a pure mechanical structure is needed, and a good solution is provided for the defects of the prior art.
