Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with the specific embodiment of the invention and
Technical solution of the present invention is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only of the invention
A part of the embodiment, instead of all the embodiments.Based on the embodiment of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
Below in conjunction with attached drawing, the technical solution of embodiment that the present invention will be described in detail offer.
In existing wind power generating set, multiple tower barrel platform plates are axially disposed with inside tower along tower, simultaneously
Tower is passed through in order to facilitate the torsion cable inside tower, through-hole is provided on the tower barrel platform plate inside tower, is located in tower
The torsion cable that generator in the cabin in portion is connected passes sequentially through the through-hole of each tower barrel platform plate and is pierced by tower, but works as wind direction
When changing, cabin box haul under yaw system control is yawed, and the torsion cable inside generator to tower also can be at this time
The rotation of cabin and rotate, when torsion beyond turn round cable can bear slew range when, turn round cable will be pulled off.
As shown in Fig. 1, it is pulled off in cabin During yaw in order to avoid turning round cable L, the embodiment of the invention provides one
Kind cable twist protective device for wind generating set, the torsion cable protection device are used to protect the torsion inside the tower T of wind power generating set
Cable L, comprising: cable bearer 1, the first cable clip 2 and the second cable clip 3；Cable bearer 1 is mounted on the lower part tower T, for carrying
It turns round cable L and torsion cable L is made to carry over tower T inner wall and be pierced by tower T downwards；First cable clip 2 is one, and the first cable clip 2 is mounted on
On the tower barrel platform plate T1 of the lower part tower T, the first cable clip 2 is for clamping torsion cable L and driving torsion cable L axial up and down along tower T
Movement；Second cable clip 3 is several, several second cable clips 3 interval is mounted between the first cable clip 2 and the top tower T
Several tower barrel platform plates T1 on, the second cable clip 3 for clamp turn round cable L and driving turn round cable L along tower T axial-rotation and
Lower movement.
Wherein, the quantity of the second cable clip 3 can be according to the tower barrel platform plate T1's inside the height and tower T of tower T
Quantity determines.
Cable twist protective device for wind generating set provided in an embodiment of the present invention when in use, when cabin is in yaw system control
When making lower box haul yaw, movement and up and down motion will be rotated with the yaw of cabin by turning round cable L, at this time due to tower T
For internal torsion cable L by 3 fixed clamp of the first cable clip 2 and the second cable clip, the rotation and up and down motion for turning round cable L will be by the
The up and down motion of one cable clip 2 and the rotation of the second cable clip 3 and up and down motion adjust to realize, and pass through the first cable
Multiple second cable clips 3 being arranged between the folder top 2 and tower T can guarantee that the rotation of this section torsion cable L is uniform；Simultaneously because the first electricity
Cable clip 2 is only able to achieve the up and down motion for turning round cable L, and the first cable clip 2 can carry out the rotation for the torsion cable L for being located at the bottom tower T
