Description

Technical Field

[0001] The invention relates to the technical field of ship mooring, in particular to a ship typhoon-proof anchor chain type secondary protection device. Background Art

[0002] The on-site environment for ship repair and modification is very complex. The ship's anchor winch and other mooring equipment often need to be dismantled, inspected and repaired due to engineering needs. Changxing Island is located at the mouth of the Yangtze River, with relatively harsh natural weather conditions and is often affected by sudden weather. When the typhoon actually arrives, it far exceeds the typhoon forecast, and other typhoon-proof cables are evenly broken. The ship has drifted with the wind. At this time, a secondary protection device is needed to protect it to prevent the ship from drifting to other docks or shallow areas. Under the condition of normal cable carrying, a windproof anchor chain is added as a safety guarantee for the ship's berthing (to cope with the impact of typhoons and severe convective weather). At the same time, the sizes of ships berthed at the dock are also different, and there is still insufficient tension when using conventional shackles to connect, so the length requirements of the windproof anchor chain are also different.

[0003] The existing Chinese patent with publication number CN213229050U discloses a typhoon protection mooring device for marine ships, including a base, which is fixedly installed on the ship deck by long bolts, and two vertical plates symmetrical about the center of the base are fixedly welded on the top surface of the base, a roller is rotatably connected between the two vertical plates through a bearing, one end of the roller passes through the vertical plate and is fixedly connected to a motor, and the other end of the roller passes through the vertical plate and is fixedly connected to a cylinder, a round rod is fixedly arranged between the two vertical plates, the round rod is located directly below the roller, and a cylinder is rotatably arranged on the outside of the round rod through a bearing, a column is fixedly welded on the top surface of the base, a limit plate is fixedly welded on the top of the column, and a brake mechanism is arranged on the cylinder.
