[0002] Wind power generation converts wind energy into electrical energy. Usually, in order to obtain the maximum amount of wind energy, the wind turbine impeller needs to change with the change of wind direction, that is, the nacelle needs to yaw. In order to cooperate with the yaw of the wind turbine, there needs to be a section of freely hanging cable in the tower, that is, the twist cable.

[0003] Currently, the twisted cables are connected to the limit plates through cable clamps. However, since the position of the cable clamps is fixed, the distance between the twisted cables is also fixed. When the twisted cables are installed and positioned, as the number of twisted cables passing through the limit plates increases, the twisted cables will come into contact with each other, which will cause the twisted cables to squeeze each other when they are offset. At the same time, as the number of twisted cables passing through the limit plates increases, the operating space of the staff will also decrease, thereby affecting the installation of the twisted cables.

[0020] The present invention also discloses a cable limiting method for a twisted cable of a wind turbine tower, which adopts the cable limiting device for a twisted cable of a wind turbine tower, and comprises the following steps:

[0021] S1: Place the limiting device inside the tower;

[0022] S2: By adjusting the position of the entire device, one end of the supporting connecting rod and the position-correcting connecting rod are in contact with the cylinder wall;

[0023] S3: Connect the supporting connecting rod to the cylinder wall with bolts, then rotate the transmission shaft and the correcting connecting rod to a position parallel to the supporting connecting rod;

[0024] S4: operating the synchronous adjustment member to adjust the distance between adjacent first clamps, and after the adjustment is completed, operating the positioning locking member to limit the first clamps;

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. By setting a synchronous positioning piece, the turntable is turned to make the movable sleeve move horizontally along the positioning screw. When the movable sleeve moves toward the turntable, the first clamp moves toward the center of the circle of the pressure ring, so that the distance between the first clamps can be reduced. Similarly, when the movable sleeve moves toward the limiting connecting plate, the first clamp moves away from the center of the circle of the pressure ring, so that the pressure ring can be moved away from the limiting connecting plate, thereby increasing the distance between adjacent first clamps. In this way, the distance between the installed twisted cables can be adjusted according to different specifications, thereby reducing the contact friction between the twisted cables and providing a larger operating space for the installation of the twisted cables.

[0028] 2. By setting a positioning locking piece, when the turntable rotates, the indexing disc drives the connecting pin to rotate. At this time, the direct-connected sleeve drives the first piston rod to move horizontally. When the first piston rod moves in a direction away from the first piston cylinder, the aqueous solution inside the second piston cylinder will be drawn into the first piston cylinder under the action of the movement of the first piston rod. Similarly, when the direct-connected sleeve moves toward the first piston cylinder, the aqueous solution inside the first piston cylinder enters the second piston cylinder. After the distance between the first clamps is adjusted, the bayonet is pulled to separate the bayonet from the first locking hole, and then the plug-in block is pushed to make the flow-blocking block block the guide hole. At the same time, the second locking hole is aligned with the bayonet again. After that, the indexing disc can be locked by inserting the bayonet pin into the second locking hole, so as to position the adjusted first clamp, thereby improving the stability of the first and second clamps in limiting the torsion cable.

[0051] The bottom of the limiting connecting plate 3 is also connected to the pressure ring 6 through the sleeve 10 and the movable rod 11. The top and bottom of the movable sleeve block 7 are rotatably connected to the second oblique connecting rod 16 through the rotating shaft. By setting this structure, when the movable sleeve block 7 moves along the adjusting screw rod 8, the pressure rings 6 at the top and bottom of the limiting connecting plate 3 move in different directions, thereby squeezing the positioning seat 13;

[0052] There are multiple positioning seats 13, and the multiple positioning seats 13 are distributed at equal distances along the center of the pressure ring 6;

[0053] The inner side of the movable sleeve block 7 is provided with a threaded hole matching the position adjustment screw rod 8 , and the top of the position limiting connecting plate 3 is provided with a through hole with a diameter larger than the inner wall diameter of the pressure ring 6 .

[0054] When the movable sleeve 7 is moved toward the rotary disc 9, the second oblique link 16 is pulled on one end of the second oblique link 16 to make the second oblique link 16 swing relative to the pressure ring 6, and the pressure ring 6 will move toward the limiting connecting plate 3, so that the first clamp 14 can be moved toward the center of the circle of the pressure ring 6, so that the distance between the first clamps 14 can be reduced. Similarly, when the movable sleeve 7 moves toward the limiting connecting plate 3, the first clamp 14 moves toward the center of the circle away from the pressure ring 6, so that the pressure ring 6 can be moved in the direction away from the limiting connecting plate 3, thereby increasing the distance between adjacent first clamps 14, so that the distance between the installed twisted cables can be adjusted according to different specifications, thereby reducing the contact friction between the twisted cables, and also providing a larger operating space for the installation of the twisted cables.

[0055] Example 3

[0056] Please refer to Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 The positioning locking member also includes a locking plate 24, a flow blocking block 29, a plug-in block 31, a first locking hole 32, a second locking hole 33, a third telescopic spring 34, and a bayonet 35. The locking plate 24 is installed at the bottom of the flow blocking connecting warehouse 22, the flow blocking block 29 is slidably connected to the inner side of the flow blocking connecting warehouse 22, the plug-in block 31 is connected to the flow blocking block 29 and extends to the bottom of the flow blocking connecting warehouse 22, the second locking hole 33 and the first locking hole 32 are both opened on the plug-in block 31, the second locking hole 33 and the first locking hole 32 are vertically arranged, the bayonet 35 passes through the locking plate 24 and is connected to the second locking hole 33, and the third telescopic spring 34 is installed between the locking plate 24 and the bayonet 35;

[0057] The center of the indexing disc 17 is misaligned with the center of the connecting pin 28. The inner wall width of the direct-connection sleeve 19 is equal to the diameter of the connecting pin 28. This structure allows the connecting pin 28 to drive the direct-connection sleeve 19 to move stably when the indexing disc 17 rotates.

[0058] The diameter of the flow blocking block 29 is larger than that of the flow guide hole 30 . The diameters of the first locking hole 32 and the second locking hole 33 are equal. One end of the locking pin 35 is equal to the diameter of the second locking hole 33 .

[0059] In this embodiment, the bayonet 35 is pulled so that one end of the bayonet 35 is separated from the second locking hole 33, and then the plug-in block 31 is pulled downward, so that the flow blocking block 29 is misaligned with the guide hole 30, and the first locking hole 32 is aligned with the bayonet 35. At this time, the bayonet 35 is released, and the bayonet 35 is inserted into the first locking hole 32 under the action of the elastic restoring force of the third telescopic spring 34, so that the first piston cylinder 21 and the second piston cylinder 25 are in a connected state. When the turntable 9 rotates, the indexing disc 17 drives the connecting pin 28 to rotate. At this time, the direct-connection sleeve 19 drives the first piston rod 20 to move horizontally. When the first piston rod 20 moves in a direction away from the first piston cylinder 21, the water-soluble solid inside the second piston cylinder 25 is released. The liquid will be drawn into the first piston cylinder 21 under the action of the movement of the first piston rod 20. Similarly, when the direct-connected sleeve 19 moves toward the first piston cylinder 21, the aqueous solution inside the first piston cylinder 21 enters the second piston cylinder 25. After the distance between the first clamps 14 is adjusted, the pin 35 is pulled to separate the pin 35 from the first locking hole 32.

Then, the pin 35 can be inserted into the second locking hole 33 to lock the indexing disc 17. In this way, the adjusted first clamp 14 is positioned, thereby improving the stability of the first clamp 14 and the second clamp 15 in limiting the twisted cable.

[0060] In combination with the above-mentioned cable limiting device for twisted cables of wind turbine towers, a cable limiting method for twisted cables of wind turbine towers is provided, which specifically includes the following steps:

[0061] S1: Place the limiting device inside the tower;

[0062] S2: By adjusting the position of the entire device, one end of the supporting connecting rod 1 and the position-correcting connecting rod 5 are in contact with the cylinder wall;

[0063] S3: Connect the supporting link 1 to the cylinder wall with bolts, then rotate the transmission shaft 4 and the correcting link 5 to a position parallel to the supporting link 1;

[0064] When the movable sleeve 7 moves toward the rotary plate 9, the second oblique link 16 is pulled on one end of the second oblique link 16 to make the second oblique link 16 swing relative to the pressure ring 6. At the same time, the pressure ring 6 will move toward the limiting connecting plate 3, so that the first clamp 14 can be moved toward the center of the circle of the pressure ring 6, so that the distance between the first clamps 14 can be reduced. Similarly, when the movable sleeve 7 moves toward the limiting connecting plate 3, the first clamp 14 can be moved toward the center of the circle away from the pressure ring 6, so that the pressure ring 6 can be moved in the direction away from the limiting connecting plate 3, thereby increasing the distance between adjacent first clamps 14, so that the distance between the installed twisted cables can be adjusted according to different specifications, thereby reducing the contact friction between the twisted cables, and also providing a larger operating space for the installation of the twisted cables. When the rotary plate 9 rotates, the indexing disc 17 drives the connecting When the first piston rod 20 is moved in the direction away from the first piston cylinder 21, the aqueous solution inside the second piston cylinder 25 is drawn into the first piston cylinder 21 under the action of the first piston rod 20. Similarly, when the direct-connected sleeve 19 moves toward the first piston cylinder 21, the aqueous solution inside the first piston cylinder 21 enters the second piston cylinder 25. After the distance between the first clamps 14 is adjusted, the latch 35 is pulled to separate the latch 35 from the first locking hole 32. Then, the plug-in block 31 is pushed to make the flow blocking block 29 block the guide hole 30. At the same time, the second locking hole 33 is aligned with the latch 35 again. Then, the latch 35 can be inserted into the second locking hole 33 to lock the indexing disc 17, thereby positioning the adjusted first clamp 14 and improving the stability of the first clamp 14 and the second clamp 15 in limiting the twist cable.

[0065] S5: The torsion cable is then passed through the limiting connecting plate 3, and the second clamp 15 is then connected to the first clamp 14 by bolts, so that the first clamp 14 and the second clamp 15 clamp and limit the torsion cable.
