Abstract
The utility model relates to an overhead dragging energy dissipation type ship arresting system for preventing ships from colliding with a bridge. The system comprises an arresting cable which is higher than a water surface, gravity anchors and a platform for placing the gravity anchors, or the arresting cable which is higher than the water surface and the gravity anchors with support legs. The height of the arresting cable is higher than the maximum heights of bows and sterns and lower than the heights of works on the ships. In order to raise the arresting cable, a support is arranged at the tops of the gravity anchors or an auxiliary pile is added. In order to prevent failure of dragging of the gravity anchors which is buried due to silting of silt and sand, the gravity anchors are placed on the platform with a certain height or the support legs are arranged at the bottoms of the gravity anchors. When the ship collides with the arresting cable, the arresting cable and the gravity anchors at two ends of the arresting cable are driven to move to the position of the bridge, and the kinetic energy of the ship is dissipated during the dragging. The interaction force between an anti-collision system and the ships and the dragging distance can be designed according to the specific conditions such as the tonnage of the fortified ships, the speed of the ships, the flow rate, the wind speed and the like, thereby not only protecting the bridge, but also being conductive to reducing the loss of the ships.
