As a transportation equipment which is greatly affected by environmental factors, a ship has an increasing demand for safety. At present, the main basis for judging the ship condition and the navigation state of a crew is still the combination of operation experience and theoretical knowledge, so that the decision-making errors are easy to occur, and unnecessary loss of manpower, material resources or financial resources is caused. Nowadays, most of ships leave or lean against a wharf and depend on the cooperation of tugboats and cable cars on the ships, but when the ships stop and approach the wharf, large impact force is usually generated on the wharf, and in order to avoid irreversible damage to the ship body of the ships caused by the wharf, a plurality of tires or other rubber products are usually hung on the wharf to relieve the impact force when the ships stop and protect the ships; however, the conventional tires or other rubber products have low structural strength and poor suspension stability, and are difficult to effectively buffer when a ship stops.

At present, chinese patent publication No. CN207987870U discloses a multistage buffering and damping device for ship berthing, in which a rubber bumper connected to the front end of a first bumper contacts a ship close to a dock, the generated impact force presses the first bumper, the first bumper presses a damper through an upper ejector rod, and the impact force is buffered and transmitted to a second bumper through an energy-absorbing buffer; the second anti-collision plate pushes the damper and the third anti-collision plate through the lower ejector rod, further buffers the impact force and transmits the impact force to the third anti-collision plate; the third anticollision board receives the impact force effect to slide compression spring along the support column, cushions the impact force, and it has effectively solved when boats and ships berth near the pier, and the degree of difficulty is big in berthing, lacks necessary buffer, leads to the impaired problem of boats and ships.

Although the multistage buffering and damping device for ship docking can provide a buffering effect for ships, when the ships have large arrival angle deviation, the ship bow directly collides with the device, so that the device cannot play any buffering effect and has large influence, and therefore, the multistage buffering and damping device for ship docking is necessary to solve the problems.
