Cable isolating and fixing device and tower tube

Abstract

The invention relates to a cable isolating and fixing device and a tower tube. The cable isolating and fixing device comprises a support ring, a plurality of flexible support bars and a plurality of cable installation assemblies, wherein the support ring comprises a through hole and a ring body enclosing the through hole; the ring body comprises an inner surface and an outer surface; the plurality of flexible support bars are arranged on the support ring at intervals; each flexible support bar is provided with opposite connection end and free end; each connection end is connected to the ring body and each free end extends away from the ring body; each flexible support bar has self-support property and predefined buffer deformation force; and the cable installation assemblies are arranged at the free ends of the flexible support bars respectively and are used for installing one or more cables. According to the cable isolating and fixing device, protection can be formed on the cables and the cables can be prevented from being twisted together.

Description

technical field [0001] The invention relates to the technical field of cable protection equipment, in particular to a cable isolation and fixing device and a tower. Background technique [0002] As one of the most commonly used transmission wire methods, cables are widely used in various industries such as aerospace, bridge construction, ships, and wind power generation. An optimized layout plan and correct installation method are one of the important conditions to ensure the normal operation of the equipment. [0003] For example, in the field of wind power technology, many megawatt-level towers use a lot of suspended cables, and the cables are connected to the external grid from the hub through the nacelle and the tower. The cables will be twisted when the tower is yawed. Regardless of whether the converter is located in the nacelle or under the tower, power cables and control cables are required to connect the nacelle and the equipment at the bottom of the tower.

AI Technical Summary

Problems solved by technology

However, due to the lack of effective protection, this section of cable will swing with the swing of the tower when the wind is strong, and will collide with adjacent structural parts, causing damage to the cable; at the same time, the rotation of the nacelle will generate a certain torque. The cables will be entangled irregularly. As the torque increases, the greater the force on the cables, it will cause certain damage, affect the normal operation of the fan, and cause economic losses.
