Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to an automatic wiring device for communication cables of wind turbine blades. Background Art

[0002] With the continuous development of wind power technology, the efficiency and reliability of wind turbines, a key component of renewable energy, have become a focus of industry attention. As key components that capture wind energy and convert it into mechanical energy, wind turbine blades require not only a large number of electrical components and sensors to monitor and control their operating status, but also complex communication cables to enable data transmission between the blades and the control system.

[0003] Currently, wiring communication cables inside wind turbine blades is mostly done manually. However, due to the typically large size of wind turbine blades (maximum lengths reaching tens of meters), manual wiring is not only inefficient but also particularly inconvenient when working in high or hard-to-reach locations within the blades, and even poses certain safety risks. Furthermore, manual wiring can lead to irregular cable layouts, hindering subsequent maintenance. Currently, no effective solutions have been proposed to address these technical issues.

[0009] Furthermore, in order to provide power for the rotation of the transmission motor, a battery is fixedly mounted on one side surface of the support shaft, and the battery is electrically connected to the transmission motor through a wire.

[0010] Furthermore, in order to increase the friction between the surface of the rolling wheel and the inner wall of the fan blade body, a rubber anti-skid pad is fixedly installed on the surface of the rolling wheel.
