AI Technical Summary

Technical Problem

The existing bridge anti-ship collision facilities are too rigid, which can easily cause local overload of the ship, resulting in damage to the ship or damage to the bridge piers.

Method used

Anti-collision facilities with dot matrix filled thin-wall structure, including anti-collision panels and honeycomb deformation space grid structures. The anti-collision panels are covered outside the space grid structure. The space grid structure has a yield hole, which can be used to impact the ship. Elastic deformation occurs, increasing the contact area and reducing impact force.

Benefits of technology

Through the elastic deformation of the space grid structure, the local impact force of the ship during impact is reduced, the ship and the piers are protected, and the huge impact on the stability of the piers is avoided.

Abstract

The utility model provides an anti-collision facility of a dot matrix filling thin-wall structure, which comprises an anti-collision panel and a space grid structure, the anti-collision panel is coated on the outer wall surface of the space grid structure, and the space grid structure is provided with an abdicating hole. In the process that a ship collides with an anti-collision facility, the space net-shaped structure elastically deforms, the contact area of the ship and the anti-collision facility is increased in the deformation process, local impact on the ship is reduced, the influence of huge impact on the stability of the bridge pier is prevented, the space net-shaped structure recovers elastic deformation after collision, and the stability of the bridge pier is improved. And the initial state of the impact money is recovered, and preparation is made for the next accidental ship impact. The large damage to the ship or the pier in the process that the ship collides with the anti-collision facility is effectively relieved.
