Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a wind power generator cable anti-wear device. Background Art

[0002] At present, the installed capacity of wind turbines is getting larger and larger. There are a large number of control cables, power cables, communication cables, etc. in wind turbines. There will be dozens of meters of hanging parts in the tower. When the wind turbine is yawed, the cables hanging in the tower will swing greatly with the twisting of the wind turbine and rub against each other. Therefore, the cables will rub against each other, causing cable wear, and the cables need to be limited for protection.

[0003] The existing patent CN220544648U discloses a wind turbine cable wear-proof device, including a support frame and a limit cylinder, wherein the front end of the support frame is fixedly connected to the ladder in a symmetrical manner, and the rear end of the support frame is fixedly connected to an adjustment arm in a symmetrical manner, and the adjustment arm is welded to the side wall of the limit cylinder in a symmetrical manner, and the limit cylinder is composed of two symmetrical half cylinders, and the upper and lower edges of the joint seam of the two symmetrical half cylinders are provided with latch holes, and the latch holes are fixedly connected by bolts passing through in sequence, and a wire splitter is provided on the inner axis of the limit cylinder, and a threading hole is provided on the outer side of the wire splitter. By providing a wire splitter and a cable bundle device, the cables can be separated from each other, and damage caused by mutual friction between the cables can be avoided. Secondly, by providing a limit cylinder, the cable can be prevented from shaking significantly when the wind turbine is yawed, and a rubber layer is provided on the inner wall of the limit cylinder to prevent the cable from rubbing against the inner wall of the limit cylinder and causing damage.

[0004] Based on the search of the above patents and in combination with the anti-wear devices in the prior art, it is found that when the above anti-wear device is in use, the cables are limited by the use of cable dividers and cable dividing holes to prevent the cables from rubbing against each other, and the cables are bound and fixed by cable ties. However, in actual use, the cable tie needs to pass through multiple threading holes, which is troublesome during the threading process. In addition, when the cable is fixed, the cable needs to be pushed inside the cable tie, which makes the installation process of the cable tie more complicated, thereby reducing its practicality.
