A kind of intelligent early warning ship collision prevention graded buffer system and energy consumption device design method

Abstract

The invention relates to the field of bridge protection, and discloses an intelligent early warning ship collision prevention graded buffer system and an energy consumption design method. The first-level anti-collision structure includes brackets, flexible armor, underwater energy dissipation devices, support ropes and anchor ropes. The brackets are fixed on the bridge piers, and the support ropes pass through the flexible The armor is connected with underwater energy dissipation devices at both ends. The flexible armor is located on the outside of the secondary anti-collision structure and is tightened on the bracket through the support rope. The two ends of the anchor rope are respectively installed on the underwater energy dissipation device and the bridge pier. superior. By setting up two levels of protection, the collision of ships with a tonnage of less than 500 tons can be completely absorbed by the primary anti-collision structure. The high-level anti-collision structure is easy to recover and avoids the overall damage of the system.

Description

technical field [0001] The invention relates to the field of bridge protection, in particular to an intelligent early warning ship collision prevention graded buffer system. Background technique [0002] With the construction of large-scale bridges in China, the problem of anti-ship collision of bridges, especially piers, needs to be effectively solved. The protection of large-scale bridges is related to social and public safety, and it is the guarantee of the safety of people's lives and property. Traditional bridge anti-collision devices often use pier outsourcing boxes. The form of plate steel structure, or the method of simply blocking the cable and adding the energy dissipator, and rarely has the warning function. [0003] The following issues remain: [0004] (1) Protective devices without monitoring and early warning functions, insufficient disaster information control capabilities, and untimely disaster perception. [0005] (2) The form of protection is single, and...

Problems solved by technology

[0004] (1) Protective devices without monitoring and early warning functions, insufficient disaster information control capabilities, and untimely disaster perception

[0005] (2) The protection form is single, and ships of different tonnages are intercepted in the same mode. After the traditional device collides with small and medium energy levels, the damage to the hull, protective structure and bridge is large, the recovery of the protective structure is difficult, and the resilience of emergency disaster prevention is poor.

[0006] (3) For the method of single arresting cable or arresting cable plus energy-dissipating anchor, its energy consumption mode is unstable. Due to the complex situation of underwater rock and soil, it is very easy to fail to move the anchor, resulting in excessive collision force and device damage

[0007] (4) Traditional energy consumers often use friction and plastic deformation to dissipate energy, which cannot be recycled and is not easy to recover

[0008] (5) The working tension of traditional energy consumers is fixed. Once a single energy consumer is started, it maintains the same working tension for collisions at different speeds, and there is no self-adaptive feature, resulting in greater internal force under low-speed and small energy level collisions.
