Combined energy dissipation type ship arresting facility using arresting cables to lift energy dissipation anchors

Abstract

The invention discloses a combined energy dissipation type ship arresting facility using arresting cables to lift energy dissipation anchors, and belongs to the technical field of bridge ship collision prevention. The facility comprises a floating foundation, an arresting net, mooring anchors, mooring anchor cable chains, energy dissipation anchors, energy dissipation anchor cable chains and connecting cable chains. The energy dissipation anchors are arranged on a mud surface below the floating foundation, and in the process of pushing the arresting facility to move towards a bridge after shipcollision, arresting cables pull the connecting cable chains to lift the energy dissipation anchors out of sludge, so that the defect that the energy dissipation anchors are prone to sinking into thesludge and cannot walk is overcome. In the anchoring walking energy dissipation process, energy dissipation anchor chains are used for stretching elastic-plastic cable bodies to dissipate energy, thus even if all the energy dissipation cables of the floating foundation play a role, resistance can be provided and ship kinetic energy can be consumed through the energy dissipation anchors, and therefore organic combination of heavy object lifting energy dissipation, anchor walking energy dissipation, stretching cable body energy dissipation and friction energy dissipation is achieved, the construction and maintenance cost is low, and a large ship is blocked more technically and economically.

Description

technical field [0001] The invention relates to an arresting ship facility for protecting a bridge section of a non-navigable hole, in particular to a mooring floating arresting ship facility. Background technique [0002] In the process of arresting a ship, there are three ways for the mooring floating arresting facility to consume the kinetic energy of the ship: lifting heavy objects for energy dissipation, anchoring for energy dissipation, and stretching cable body for energy dissipation. The existing arresting ship facilities only use one of the energy dissipation methods. Although it can achieve the purpose of arresting ships and protecting bridges, it is often not economical. Using two or three energy dissipation methods at the same time is more conducive to exerting various energy dissipation methods. Advantages of energy dissipation. [0003] For arresting facilities using anchors for energy dissipation, if the energy dissipation anchor is placed directly on the mud...

Problems solved by technology

The existing arresting ship facilities only use one of the energy dissipation methods. Although it can achieve the purpose of arresting ships and protecting bridges, it is often not economical. Using two or three energy dissipation methods at the same time is more conducive to exerting various energy dissipation methods. Advantages of energy dissipation

[0003] For arresting facilities using anchors for energy dissipation, if the energy dissipation anchor is placed directly on the mud surface, it is easy to sink into the mud and may not be able to pull the energy dissipation anchor after the ship hits, resulting in failure of the arresting facility; if the energy dissipation anchor is placed on the floating foundation Or suspended under the floating foundation, it will increase the displacement of the floating foundation and increase the mooring force of the floating foundation under the action of waves, and the application in the ocean environment with large waves will increase the construction cost and maintenance cost of the arresting facility

[0004] As for the arresting facilities using tension cables to dissipate energy, due to the limited length of energy-dissipating cables that can be installed on a single floating foundation, only a single arresting unit at the ship’s collision position can play the arresting role, and it is difficult to exert the overall arresting function of the arresting facility. Large ships are difficult and lead to high construction costs of arresting facilities
