Description

Technical Field

[0001] The invention belongs to the technical field of cable installation of wind turbine generators, and in particular relates to a cable protection clamping plate structure for wind turbine generators. Background Art

[0002] Wind turbines are devices that convert wind energy into electrical energy, and transmit the converted electrical energy to other places through cables for use by power-consuming devices. Usually, the power cables of wind turbines are laid vertically from the top of the wind turbine along the wall of the tower to the bottom of the tower. However, due to the heavy weight and long length of the cables themselves, the cables will slide down and vibrate in the tower, thus affecting the installation or use of other devices in the wind turbine. At the same time, the cables themselves will also be subject to a certain degree of wear and tear, and there is even a risk of breakage. For example, CN105024317A discloses a wind turbine power cable fixing device, including a power cable upper clamp, a power cable lower clamp, a fastening bolt, a fastening nut, a lower clamp fixing hole, a lower clamp fixing plate and a power cable anti-wear layer, wherein the power cable upper clamp is arranged on the upper part of the power cable lower clamp; the power cable lower clamp is located between the lower clamp fixing plates; the lower clamp fixing hole is arranged in the middle of the lower clamp fixing plate; the lower clamp fixing plate is arranged at both ends of the lower part of the power cable lower clamp; the power cable anti-wear layer is bonded to the inner edges of the power cable upper clamp and the power cable lower clamp. The fixing device can only clamp and fix a single cable when in use, but in an actual wind turbine generator set, it is usually necessary to install multiple cables, and then multiple fixing devices need to be installed when in use, which makes the overall installation operation inconvenient.
