Collision buffer device for large marine structures

Abstract

A collision buffer device for large marine structures, comprising two supporting bases corresponding to each other, a slideway is arranged on the supporting base, a slider is installed in the slideway, the slider is pivotally connected with two brackets through a hinge unit, and the two The two brackets are pivotally connected together through a rotatable shaft body, and an elastic unit is respectively connected between the two brackets, and a collision buffer device capable of adjusting distance and rigidity is formed through the above connections. The invention has a simple structure and is easy to disassemble. It can not only buffer the collision of various large floating marine structures when they approach, but also adjust the distance between two approaching floating bodies; at the same time, it increases the contact with the hull. On the other hand, the degree of damage to the hull and the production cost are reduced.

Description

technical field [0001] The invention relates to a collision buffer device, in particular to a large-scale ocean structure collision buffer device. It belongs to the field of shipbuilding and offshore oil engineering. Background technique [0002] As we all know, the shortage of oil resources and the growing demand for energy from the international community have led to large-scale development of offshore oil and gas fields. The large-scale model development of offshore oil has accelerated the design and construction of a large number of marine structures. In the field of marine engineering, it often occurs that two or more floating bodies are close to each other. Under the action of wave force, the close objects may collide due to the relative motion between them. In order to prevent damage to the two hull structures during collision, a collision buffer device is usually installed between the two objects. [0003] At present, in order to avoid the direct collision of two ...

AI Technical Summary

Problems solved by technology

[0005] (1) The distance between two floating bodies can only be determined by the size of the rubber pad between the two floating bodies. The size of the existing rubber pad cannot be changed, so the distance between the two floating bodies is also non-adjustable

[0006] (2) The contact surface between the rubber pad and the hull is generally small, which will cause stress concentration on the side chord of the hull, thus causing damage to the hull

[0007] (3) The rubber pad is easy to age under the action of seawater, and the life cycle is short
