Multi-layer cable storage reel for coiling large cross-section super-length submarine cable and method of use thereof

Abstract

The invention discloses a multilayer cable storage tray for coiling of a large-section extra-long sea cable and a using method thereof, which relate to a sea cable storage tray. Expanding the storagecapacity of the storage cable tray on the existing construction platform is a technical problem that needs to be broken through at the stage. The multilayer cable storage tray comprises an inner fence, an outer fence, a bottom plate and a round partition, wherein the bottom plate is round; the inner fence, the outer fence and the bottom plate are matched to form a cable storage cavity with an upward opening; the partition is transversely arranged to divide the cable storage cavity to multiple layers of cable storage rooms; and the partition is provided with arc grooves for enabling a cable topass through and a gap adjusting mechanism for adjusting the width of the arc groove. In the technical scheme of the invention, the cable storage tray is divided to multiple layers of cable storage rooms through the partition, the cable storage room in each layer bears a force independently, and when the cable storage room at a lower layer achieves a force bearing limit, through adding the partitions and building an upper-layer cable storage room, more cable storage capability is increased, the storage capacity of the storage cable tray can be effectively enhanced, and continuous coiling of the sea cable is realized; and as the gap adjusting mechanism is arranged, a sea cable with a different diameter can pass, and the working reliability is improved.

Description

technical field [0001] The invention relates to a submarine cable storage reel, in particular to a multi-layer cable storage reel used for coiling a large cross-section super-length submarine cable and a method for using the same. Background technique [0002] With the implementation of the national marine power strategy, the market demand for submarine cables has increased significantly, and higher requirements for voltage levels have also been put forward. Under this background, the length and cross-sectional area of ​​the submarine cable have increased significantly, which puts forward higher requirements for the storage capacity of the cable storage drum. The existing cable storage device has only one layer, which is composed of inner and outer fences and a bottom plate. The radius of the inner fence is larger than the allowable bending radius of the submarine cable. The height of the fence is closely related to the number of layers of cable storage, and the number of la...

AI Technical Summary

Problems solved by technology

Considering the force of the bottom submarine cable, the height of the fence of the cable storage reel cannot be increased infinitely. When the submarine cable is a large cross-section super-length submarine cable, in order to meet the requirements of the cable storage capacity, the outer fence of the cable storage reel can only be increased. diameter, which not only occupies a larger area of ​​the construction platform, but also puts forward higher requirements for the construction platform. The traditional method is to transform and expand the cable storage reel and the submarine cable construction platform, or the deck area of ​​the submarine cable construction ship It is limited to cut off a single submarine cable for transportation and construction separately, which not only increases the cost of making and installing submarine cable joints, but also increases the risk of operation and maintenance of the submarine cable. Therefore, how to expand the storage cable on the existing construction platform The amount of cable storage is a technical problem that needs to be broken through at this stage
