Multi-core-tube anti-collision capsule

Abstract

The invention discloses a multi-core-tube anti-collision capsule, which belongs to the technical field of structural protection, and can effectively realize collision protection of structures such as piers through corresponding arrangement of a shell, a central plug in the shell, a core tube and the like and combined work of a one-way valve and a pressure regulating valve in the central plug. The acting force acting on the protected structure in the collision process is controlled and released, and reliable collision prevention of the structure is achieved. The multi-core-tube anti-collision capsule is simple in structure and easy and convenient to arrange and maintain, collision protection of structures such as piers can be effectively achieved, the acting force transmitted to a protected structure by the anti-collision capsule in the collision process is effectively controlled, the collision impact force does not exceed the bearing capacity of a protected object, and after collision is removed, the anti-collision capsule can be quickly recovered under the action of the core tube, so that the anti-collision capsule can quickly recover the state before collision, the overhaul and maintenance process of the anti-collision capsule is effectively simplified, and the anti-collision capsule has better application prospect and popularization value.

Description

technical field [0001] The invention belongs to the technical field of structural protection, and in particular relates to a multi-core tube anti-collision capsule. Background technique [0002] In recent years, with the increasing number and tonnage of ships sailing on rivers, incidents of ships colliding with bridge piers have occurred from time to time. Ship-bridge collisions often cause catastrophic consequences such as ship-bridge structure damage, cargo leakage, environmental pollution, and casualties. Therefore, on the bridge piers, safety measures or protective devices are often provided to ensure the stability and safety of the structure under the impact of the ship. [0003] At present, common pier protection devices can be divided into two categories: direct construction and indirect construction. Among them, direct construction means that the protection device is directly constructed on the protected pier, and after the impact occurs, the impact force directly ...

AI Technical Summary

Problems solved by technology

However, the structure of the above-mentioned anti-collision capsule itself is relatively complicated, and the assembly, maintenance, and overhaul are relatively cumbersome, which affects the application and promotion of the anti-collision capsule to a certain extent, resulting in the inability to achieve reliable protection for bridge piers.
