Ship-bridge collision protective energy-absorption device

The utility model provides a ship-bridge collision protective energy-absorption device, and belongs to the technical field of civil engineering ship-bridge collision. The ship-bridge collision protective energy-absorption device is composed of energy-absorption block units, a periphery steel board box and stab-preventing fibers. Steel boards are connected in a spliced mode to form the steel board box, the energy-absorption block units are stacked in the steel board box tightly and regularly, the lower portion of the steel board box is provided with a foam floating board, and the outer side of the steel board box is provided with stab-preventing fiber cloth. The energy-absorption block units are composed of round steel pipes and elastic polyurethane foam blocks, two deformation work stages are used when impact loads are resisted, and the energy-absorption effect is improved. The ship-bridge collision protective energy-absorption device has the advantages that a ship bow is prevented from stabbing the device, the collision-preventing and energy-absorption effect is enhanced, replaceability of the energy-absorption block units and the steel boards constituting the steel board box is achieved, and elastic polyurethane foam can recover after deforming.
