Description

Technical Field

[0001] The utility model relates to the technical field of wind power tower equipment, in particular to a cable fixing device for a wind power tower. Background Art

[0002] Wind power tower cable fixtures are usually designed to fix cables on wind power towers to ensure that they are safely and firmly connected and avoid loosening or damage during operation. Such devices are crucial in wind power generation systems because cables are often subject to wind, vibration and other environmental factors.

[0003] Such devices may include a variety of auxiliary structures and anti-loosening mechanisms to ensure that the cable is firmly fixed. For example, auxiliary structures may include components such as screws, grooves, clamps and barrels, which are designed to allow users to adjust the position and tightness of the cable as needed. Anti-loosening structures may include components such as push rods and discs, which are used to limit the diameter of the internal channel of the cable fixing device to prevent the cable from loosening.

[0004] Such devices can not only protect the cables from damage by the external environment, but also ensure their normal operation and long-term stability. At the same time, the design of these devices usually takes into account the convenience of installation and maintenance, to ensure that operators can easily install, adjust and maintain them, thereby improving the reliability and efficiency of the entire wind power generation system.

[0005] The application number is CN201820717390.8. The cable fixing device of the wind power tower comprises a steel wire rope, a nut, a section arm, a support module, a fastener, a hoop, a bevel gear shaft and a rod frame. The steel wire rope is fixed by rotating through the nut on the side of the bottom end and is fastened to the top of the rod frame. The bevel gear shaft is composed of an inner rotor, a transmission gear, a bushing, a rotating shaft, a bearing and a limit pin. The utility model provides a cable fixing device for a wind power tower. The side corners of the section arm are split and folded on the inner wall to increase the bevel gear shaft. The transmission gear is then adjusted along the contraction and extension of the section arm to rotate the inner rotor to transmit the driving force, so that the bushing is fixed to it during the mechanical transmission process and the load friction coefficient is reduced to maintain the horizontal torsion of the bearing. However, the fixing structure of the device is very complicated and not simple enough when used.
