Description

Technical Field

[0001] The present invention relates to the technical field of ship equipment, and more specifically, to a ship connected high-freedom fender device. Background Art

[0002] Fenders, also known as ship guards, are elastic buffer devices used on the side of ships. They are mainly used to reduce the impact force between ships and docks or between ships during docking or mooring, and to prevent or eliminate damage to ships and docks. The existing anti-collision fenders of ships are mainly one-piece rubber fenders. At the beginning of ship construction, the position and height must be confirmed with the shipowner according to the port requirements. Once confirmed, the position and height of the fenders are difficult to adjust. However, sometimes the confirmed height cannot fully utilize these tire fenders in actual use. For example, different water levels, different ship working conditions, and different port dock heights will cause the relative height of the ship and the dock to change. Therefore, although the tire fenders installed at a fixed height can play a protective role most of the time, there are still times when they cannot protect, which reduces the buffer reliability and scope of application of the tire fenders. In addition, the existing fender devices require the crew to manually adjust them one by one, which makes the tire fender adjustment efficiency low and the height adjustment error of multiple tire fenders large, which reduces the impact protection effect on ships and docks.

The fourth magnetic coil is fixedly embedded in the spiral groove on the inner wall of the second selection transmission tube 18. When direct current is passed into the fourth magnetic coil to generate a magnetic field, the second selection transmission tube 18 is pushed to slide axially relative to the first selection transmission tube 16, thereby driving the fourth end gear plate 21 to mesh and transmit with the second end gear plate 12. Furthermore, the second slider on the inner wall of the second selection transmission tube 18 is axially slidably matched with the second slide groove on the outer wall of the first selection transmission tube 16.
