Description

Technical Field

[0001] The utility model belongs to the technical field of wind turbine sets, and in particular relates to a cable hanging bracket for wind turbine sets. Background Art

[0002] The electric energy generated by the wind turbine generator set is transmitted to the power grid through the tower cable. Therefore, a section of the cable from the nacelle to the tower is suspended from the center line of the tower so that the cable can be twisted within a certain angle. The force of the wind drives the tower and the nacelle to swing, which causes the cable to swing. When the wind force in the external environment is strong, the strong wind will cause the cable to swing continuously, and rotate continuously, and even collide with the tower, damaging the cable.

[0003] For example, a Chinese patent with publication number CN202157916U discloses a wind turbine generator set, including a relatively arranged cover body and a shaft body, wherein the shaft body is at least partially located in the cover body, and the rest of the shaft body extends out from the through hole of the cover body, and further includes: a sealing ring, wherein the sealing ring is fixedly arranged at the edge of the cover body through hole facing the shaft body, and the radial cross-sectional shape of the sealing ring has a tip facing the shaft body, and the tip abuts against the shaft body. The wind turbine generator set provided by the utility model adopts a rubber ring for sealing, which is easy to install, and the sealing ring can be processed by one-piece molding; the tip of the sealing ring abuts against the shaft body, and the sealing effect is good, and after the sealing ring is installed, the relative movement between the cover body and the shaft body will not be affected.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: the weight of the cable of the above device is too large. When the device needs to be replaced or repaired, the cable maintenance personnel need to remove the cable from the above device, and the heavy cable requires a lot of manpower to remove and replace the cable. At the same time, the cable of the above device is located at a high place, and there is a risk of injuring the maintenance personnel when repairing and replacing the cable. In view of this, we propose a cable hanging bracket for wind turbines. Utility Model Content
