A bending limiter for submarine cables with adaptive buffering

Abstract

The invention discloses a bent self-adaptive buffering submarine cable bend limiter, which comprises n sections of bend limiter units sequentially connected, and the bend limiter units respectively include two symmetrical bend limiter monomers, two bend limiter units The bending limiter unit is combined to form a bending limiter unit. The bending limiter body includes a bending limiter body and a soft gasket. The bending limiter body includes a male head section, a neck section and a female head section. The male head The segment and the female segment are located at both ends of the neck segment, the soft washer is embedded in the corresponding female segment, and the soft washer is provided with a first embedding groove corresponding to the male segment. Through the above method, the bend limiter of the bending adaptive buffering submarine cable shown in the present invention, before the bend limiter unit reaches the designed locking radius, through the adaptive elastic deformation of the soft gasket, the small bending effect is buffered and the strength is strengthened. In order to protect the submarine cable, it can effectively improve the service life of the submarine cable.

Description

technical field [0001] The invention relates to the technical field of submarine cables, in particular to a bending limiter for submarine cables with self-bending buffering. Background technique [0002] Submarine cable is a kind of slender and flexible structure, divided into submarine communication cable and submarine power cable, and some submarine cables have both communication and power transmission functions. The underwater environment is complex, requiring the submarine cable to have a certain degree of flexibility. When the bending deformation force of the submarine cable exceeds the radius of the bending deformation of the submarine cable itself, failure may occur, and protection is usually required. The bending limiter is a kind of Commonly used submarine cable protection devices are widely used in various submarine cable projects. [0003] The traditional submarine cable bending limiter is a cylindrical member nested outside the submarine cable. When the bending ...

AI Technical Summary

Problems solved by technology

In the ocean dynamic environment, long-term and alternating small bending effects will also cause damage to the submarine cable and reduce the service life of the submarine cable. However, the traditional bending limiter does not have the ability to buffer or resist small bending effects and needs to be improved.
