Description

Technical Field

[0001] The utility model relates to an aluminum alloy cable hanger structure in a wind power tower, belonging to the technical field of cable hangers. Background Art

[0002] With the continuous development of wind power technology, the height and performance of wind turbine towers are also constantly improving. High tower technology helps to increase the power generation of wind turbines, so the design innovation and structural optimization of wind turbine tower platform technology and accessories inside the tower have received widespread attention. In this context, the design and selection of accessories inside wind turbine towers have become increasingly important. The selection of accessories needs to consider many factors, including strength, safety, stability, durability, and ease of maintenance.

[0003] Among them, the cable hanger is an indispensable part of the accessories in the tower platform. Its main purpose is to provide basic support for the direction and safety of various machine cables on the platform. Although the traditional steel cable hanger has high mechanical properties and high reliability, it has a large deadweight due to its high mass density, which is not conducive to disassembly and transportation. In addition, the corrosion resistance of steel is poor in the wind field environment, and it is difficult to meet the 20-year use requirements, and the maintenance cost during the life cycle is high. As a light metal material, aluminum alloy has a mass density of only one-third of steel, but its strength, stability, durability and other aspects are better than ordinary steel. The entire process of production, manufacturing, processing and transportation of aluminum products is relatively friendly to the environment, and it can be recycled and reused after reaching the service life, making it more in line with the concept of environmental protection and energy conservation and emission reduction. Wind power itself is a way to obtain clean energy. The development of wind power itself is to practice the concept of environmental protection and energy conservation and emission reduction, so aluminum alloy cable hangers that are in line with the concept of environmental protection and energy conservation and emission reduction should be used.
