Description

Technical Field

[0001] The utility model relates to a submarine cable bending limiter reinforcement structure, belonging to the field of marine engineering foundation structure arrangement. Background Art

[0002] The protection requirements for submarine cables in the offshore wind power sector are relatively high, because near the mud of offshore wind power structures, bend limiters are generally used to limit the movement of submarine cables to prevent the suspended sections of submarine cables from being damaged by ocean currents. Bend limiters are generally inserted into the submarine cable protection tube and fixed under the extrusion and friction between the outer wall of the superstructure and the inner wall of the submarine cable protection tube. Due to factors such as inadequate construction, unreasonable design, and processing accuracy that does not meet requirements, bend limiters often fall off in offshore wind power projects, which greatly affects the safe operation of submarine cables.

[0003] This patent develops a new type of submarine cable bend limiter reinforcement structure by optimizing the design of existing submarine cable bend limiters and submarine cable protection tubes, which can greatly improve the reliability of the connection and fixation of the bend limiter and the submarine cable protection tube.

[0018] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0019] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present application. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present application belongs.

[0020] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0021] like Figure 1 As shown, this embodiment provides a submarine cable bending limiter reinforcement structure, including a submarine cable protection tube 1 and a bending limiter 2, the bending limiter is a conventional bending limiter; the bending limiter is inserted in the lower part of the submarine cable protection tube, and a rubber gasket 3 and a rubber sealing ring 4 are arranged between the bending limiter and the submarine cable protection tube.

[0022] In the embodiment of the utility model, the lower part of the submarine cable protection tube is composed of a curved section 5 and a bell mouth 6, wherein the curved section is a non-diameter-variable arc tube. The submarine cable is smoothly transitioned at the outlet of the submarine cable protection tube by the arc transition.

[0023] In the embodiment of the utility model, the bell mouth has a large diameter at the lower end and a small diameter at the upper end, and its upper end is connected to the lower end of the curved section. The bell mouth is small at the upper end and large at the lower end, which facilitates the insertion of the bending limiter and the submarine cable.

[0024] In the embodiment of the utility model, the bell mouth is a variable diameter steel pipe.

[0025] In the embodiment of the utility model, the shape of the rubber gasket is annular.

[0026] In an embodiment of the utility model, the rubber gasket is arranged on the top outer wall of the bending limiter.

[0027] In an embodiment of the utility model, the outer diameter of the rubber gasket is slightly larger than the inner diameter of the bending section of the submarine cable protection tube.

[0028] In the embodiment of the utility model, a plurality of rubber sealing rings are arranged along the length direction of the submarine cable protection tube.

[0029] In the embodiment of the utility model, the rubber sealing ring is in the shape of a circular ring.

[0030] In the embodiment of the utility model, two rubber sealing rings are provided along the length direction of the submarine cable protection tube.

[0031] In the embodiment of the utility model, when the bend limiter is inserted into the bending section of the submarine cable protection tube, the reinforcement structure of the submarine cable bend limiter first increases the extrusion force and friction between the bend limiter and the submarine cable protection tube by squeezing the rubber gasket, and then forms the extrusion force by the mutual engagement and extrusion of the bending section and the multiple rubber sealing rings of the bend limiter. Through the above two designs to increase the fixed connection capacity of the bend limiter and the submarine cable protection tube, the reliability of the fixation of the bend limiter is greatly improved, and the operability of the construction is also improved.

[0032] The present invention combines the structural characteristics of the submarine cable protection tube and the bend limiter to optimize the connection and reinforcement scheme of the bend limiter and the submarine cable protection tube. Compared with the traditional fixing scheme, the fixing performance of the bend limiter and the submarine cable protection tube is greatly improved, and its reliability and construction operability are improved. The structure is simple and the design is reasonable; the double fixing design of the rubber gasket and the rubber sealing ring can greatly improve the fixing effect of the bend limiter and reduce the risk of falling; the processing accuracy and friction capacity requirements of the bend limiter insertion section are greatly reduced, which reduces its processing difficulty and improves construction efficiency.

[0033] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms.
