Description

Technical Field

[0001] The utility model relates to the technical field of cable duct installation, and particularly relates to a cable duct group for the expansion installation of an offshore booster station. Background Art

[0002] The development of offshore wind power in the world is rapid and has entered the stage of large-scale development. The construction of offshore wind power in China is also developing vigorously. The development of offshore wind power is gradually on the right track, and the development of the offshore part is approaching saturation. A series of fixed foundation piles are installed offshore for offshore wind power, and wind turbines are installed on them for power generation. Then, 5 to 10 wind turbines are combined and sent to an offshore booster station, and then exported. The offshore booster station is a step-up and transformation facility built on an offshore fixed platform. Compared with a conventional onshore booster station, it has great differences in site selection, site environmental conditions, civil engineering foundation design, construction operation and maintenance, and auxiliary facilities, and has its particularity. The cost of the offshore booster platform is expensive, the construction difficulty is great, and the offshore environment is complex, with heavy salt spray and humidity. The equipment layout conditions are limited, the operation and maintenance are inconvenient, and the construction cost is high. Since the transmission capacity has been reserved and further expanded in the early-stage developed booster station, the number of cable ducts is insufficient, and separate ducts need to be installed additionally for cable laying.

[0003] It is extremely difficult to install the cable ducts on the booster station later. Since the cable ducts are long and heavy, it is not easy to transport and hoist them as a whole. If the overall installation is very difficult, there is basically no precedent for implementation in the project. Secondly, the on-site operation space is narrow. At the same time, for each additional cable duct, the workload is very large, which is not suitable for expansion construction, especially when the number to be increased is large, the construction period is long, the consumption is huge, and there is no value for implementation. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cable duct group for the expansion installation of an offshore booster station.

[0005] The utility model provides the following technical solutions:

[0006] The utility model provides a cable duct group for the expansion installation of an offshore booster station, including a plurality of cable ducts. A plurality of connecting rods are used to connect adjacent cable ducts. A plurality of chocks for connecting to the jacket of the booster station are arranged on the cable ducts. A horn-shaped opening part is arranged at the bottom end of the cable duct to facilitate the submarine cable to extend into the cable duct.

[0007] Furthermore, a riser flange is fixed to the outer edge of the top end of the cable duct.

[0008] Furthermore, the cable duct is in a shape of a reverse L.

[0009] Furthermore, a welding rod facing the booster station guide frame is also provided on the connecting rod located at the upper end of the cable conduit.

[0010] Furthermore, the upper part of all the cable conduits is connected to a horizontal bar, and both ends of the horizontal bar are provided with clamps for connecting to the booster station guide frame.

[0011] Furthermore, the lower part of the cable conduit on both sides is provided with clamps for connecting to the booster station conduit frame.
