The shape of the arc surface is generally adapted to the cylindrical shape of the clamped cable 500, so that when the cable 500 is clamped by the clamping part 131, surface contact is formed between the surface of the cable 500 and the clamping part 131, so that the cable The bearing clamping force is evenly distributed, and at the same time, the friction force between the cable 500 and the clamping part 131 is increased, so that the effect of the cable being clamped is better and the surface of the cable 500 is avoided during the clamping process. Destruction; through the design of the three clamping parts 131 , the cable clamping block 100 can clamp three cables 500 at the same time. Through the distribution structure of the three clamping parts 131 in an equilateral triangle, the three clamped cables 500 are connected to each other two by two, and the cables 500 are more compact.

Based on the understanding of those skilled in the art, the through hole of the cylindrical structure 130 can also be a cylindrical shape. At this time, one cable clamping block 100 can only clamp one cable, and the diameter of the through hole of the cylindrical structure 130 should be slightly smaller than the diameter of the clamped cable. The diameter of the cable 500 is so that the clamped cable 500 can withstand a suitable clamping force.

As shown in Figures 8-11, the twisted cable protection device provided by this embodiment also includes: a cable sheath 300, which is used to be sleeved on the outside of the four edges of the cable separator 200, and the cable sheath 300 extends out in the axial direction. Surfaces on both sides of the cable separator 200 . The cable sheath 300 can protect the cable separator 200.

During implementation, the constriction portion 310 may be in a regular conical shape, or in a spherical shape or a trumpet shape. Since the cable 500 is twisted during the rotation of the nacelle, when the cable 500 itself is twisted, the cable 500 will also be displaced in the vertical direction. Through the design of the cable sheath 300, the cable 500 will be displaced in the vertical direction. When the cable sheath 300 of the fixed cable separator 200 is displaced in the vertical direction, the design of the shrinkage part 310 can reduce the distance between the cable sheath 300 and the interior of the tower 600 when the cable sheath 300 is displaced in the vertical direction. Collision with other structures of the cable sheath, thereby protecting the safe use of the entire cable sheath 300 and the cable partition 200 inside the cable sheath.

The fixing plate can be integrally formed with the cable sheath 300, or can be fixed on the cable sheath 300 by welding or screwing. The interior of the sheath 300 .

A notch 321 is provided on the fixing plate 320 at a position corresponding to the partition hole 212 , and the shape of the notch 321 is adapted to the partition hole 212 . Through the design of the gap 321, the size of the entire cable sheath 300 can be reduced, making the structure of the cable sheath 300 and the cable partition 200 more compact, and the layout is also more reasonable. While reducing the size of the plate 200, the overall weight of the entire twisted cable protection device can also be reduced, thereby reducing the tension on the cable 500.

As shown in Figures 12-13, the twisted cable protection device provided by this embodiment also includes an anti-collision retaining ring 400, which is arranged outside the cable sheath 300, and between the inner wall of the anti-collision retaining ring 400 and the cable sheath 300 There are gaps in between. As mentioned above, when the cable sheath 300 shakes inside the tower 600, the kinetic energy of the cable sheath 300 shaking can be effectively absorbed by the anti-collision retaining ring 400, so as to avoid the excessive shaking of the cable sheath 300, and it can also When the entire cable sheath 300 is displaced in the vertical direction, it acts as a guide for the cable sheath 300 to make the cable sheath 300 move vertically along the anti-collision retaining ring 400 .

Both ends of the anti-collision retaining ring 400 are respectively provided with flared portions 410 , and the inner diameter of the flared portions 410 gradually increases from the main body of the anti-collision retaining ring 400 to both ends along the axial direction. During implementation, the flaring portion 410 may be in a regular conical shape, or in a spherical shape or a trumpet shape. When the vertical displacement of the cable sheath 300 is too large, in the process of resetting the cable sheath 300, the flared part 410 can effectively guide the cable sheath 300 back to the inside of the anti-collision retaining ring 400 to avoid the cable sheath The edge of the sleeve 300 makes a hard impact (point-to-face or point-to-point impact) with the bumper ring.

Optionally, the anti-collision retaining ring 400 can be formed by connecting two or more retaining rings separately. The split connection method can facilitate the installation of the anti-collision retaining ring 400. After the cable sheath 300 and the upper cable partition 200 and cable clamp block 100 are installed, it is only necessary to place the cable sheath on the anti-collision For the installation position of the retaining ring 400, the split structures of the anti-collision retaining ring 400 are connected and formed by auxiliary tools. Such a structural design also facilitates disassembly and replacement of the anti-collision retaining ring 400 during maintenance.
