A submarine cable protection tube assembly for offshore wind power generation

Abstract

The invention discloses a submarine cable protective tube assembly for offshore wind power generation, which belongs to the field of cable protective tubes. By installing a plurality of double-layer protective tubes on the cables according to actual needs, the loose placement of part of the cables inside the double-layer protective tubes is realized. , forming a reserved cable area. When the cable migrates excessively on the seabed, the double-layer protective tube can automatically stretch, release the reserved cable, and adapt to the pulling force of the external environment, thereby effectively reducing the tensile damage to the cable. When the external force disappears When the double-layer protective tube is retracted automatically, the reserved cable is re-formed to provide protection for the next cable tension process. Moreover, when the cable is intercepted by foreign objects and the double-layer protective tube cannot be retracted, the air pump can simultaneously send multiple The interior of the double-layer protective tube is inflated, so that its expansion drives the cables to float together, and the foreign objects can be quickly and effectively separated, which not only reduces the damage to the cables by foreign objects, but also promotes the re-formation of the reserved cables, and realizes the effective protection of the cables. Protect.

Description

technical field [0001] The invention relates to the field of cable protection tubes, and more specifically relates to a submarine cable protection tube assembly for offshore wind power generation. Background technique [0002] Wind power is the fastest growing green energy technology in the world. While the construction of onshore wind farms is developing rapidly, people have noticed some restrictions on the utilization of onshore wind energy, such as large land occupation and noise pollution. Due to the abundance of offshore wind energy resources and the feasibility of today's technology, the ocean will be a rapidly growing wind power market. [0003] Submarine cables are wires wrapped with insulating materials and laid under the seabed and rivers for telecommunication transmission. Modern undersea cables use fiber optics to transmit telephone and internet signals. The optical fiber has the characteristics of safety and stability, strong anti-interference ability, and goo...

Problems solved by technology

[0004] However, due to the complex sea conditions on the seabed, with the long-term erosion of the seabed silt by the sea bottom current, and the swaying of the wind turbine at sea, it is easy for the submarine cable to be suspended in the air, and it will be suspended and displaced with the sea water and the wind turbine, resulting in cable failure. In the case of tensile damage
