Detailed Description

The present invention is further illustrated by the following examples in conjunction with the accompanying drawings, but the invention is not limited thereby in the scope of the examples described.

As shown in fig. 3, the present invention provides a fan twist cable apparatus 100. The wind turbine twisting device 100 is used for being installed inside a tower of a wind turbine and limiting a cable 200 in the tower. The upper end of a cable 200 in the tower of the wind turbine is connected to power generation equipment in the engine room, and after the cable 200 penetrates through the tower from top to bottom, the lower end of the cable 200 is connected with an electrical cabinet at the bottom of the wind turbine. The wind direction of the wind turbine can be changed in the operation process of the wind turbine, and in order to improve the use efficiency of wind energy, the direction of the wind turbine needs to be changed in the operation process of the wind turbine, so that the central rotating shaft of the wind turbine is perpendicular to the wind direction as much as possible. The orientation of the nacelle can be changed together when the orientation of the wind wheel is changed, and the power generation equipment arranged in the nacelle can drive the cable 200 to move up and down along the axial direction of the tower when rotating. Therefore, the wind turbine twisting device 100 in the tower cannot completely fix the cable 200, and a margin for the cable 200 to move in the axial direction of the tower needs to be provided.

The cable 200 has a first fixing portion and a second fixing portion extending from the top of the tower to the bottom of the tower. The fan cable twisting device 100 comprises a first limiting component 1 and a second limiting component 2 which are separately arranged. The first limiting component 1 is used for fixing a first fixing part of the cable 200 and enabling the first fixing part to move between a first position and a second position along the axial direction of the tower. The first position-limiting component 1 is clamped at the first fixing part of the cable 200. When the wind wheel rotates around the tower to the equilibrium position, i.e. the cable 200 hangs down most along the axial direction of the tower, the first position limiting assembly 1 moves to the first position, which is the lowest point of the first position limiting assembly 1 moving down along the axial direction of the tower. When the wind wheel rotates around the tower barrel and deviates from the balance position, the deflected power generation equipment drives the cable 200 to move upwards along the axial direction of the tower barrel, and the first limiting component 1 also moves upwards; when the wind wheel rotates to the limit position, the cable 200 axially rises to the highest point along the tower, and at the moment, the first limiting assembly 1 is tightly clamped on the first fixing portion and moves upwards to the second position. The extreme position of the first limiting assembly 1 moving upwards along the axial direction of the tower is a third position, and the third position is higher than the second position.

The position of the first fixing portion on the cable 200 needs to be determined after the fan cable twisting device 100 is installed, that is, the cable is fixed when the first limiting assembly 1 is located at the first position, and the position of the fixing portion is the first fixing portion of the cable. It will be appreciated by those skilled in the art that the position of the first fixing portion on the cable 200 is not limited to the first position of the first limiting member 1, and it is preferable to leave a margin in order to avoid the cable 200 between the power generating equipment in the nacelle and the first limiting member 1 being under tension.

The second limiting component 2 is used for fixing a second fixing portion of the cable 200, and the second fixing portion is located below the first fixing portion along the direction of the cable 200 extending from top to bottom. However, the second fixing portion is not necessarily located below the first fixing portion in the axial direction of the tower. The second limiting component 2 is clamped on the second fixing part, and the second limiting component 2 does not interfere with the first limiting component 1 to move.

In this embodiment, when the first limiting component 1 moves up and down along the axial direction of the tower, the second fixing portion of the cable 200 does not change position relative to the tower, and the second limiting component 2 does not affect the movement of the first limiting component 1.

In some embodiments, the second position-limiting component 2 is also configured to be similar to the first position-limiting component 1 such that the second fixed portion of the cable 200 can also move.

The position of the second fixing portion on the cable 200 also needs to be determined after the fan cable twisting device 100 is installed. That is, when the first stopper member 1 is positioned at the third position, the second stopper member 2 fixes the cable 200 at the second fixing portion of the cable. The cable 200 between the first fixing portion and the second fixing portion also has a margin so that the first fixing portion can drive the first limiting component 1 to move along the axial direction of the tower, and the movement of the first limiting component 1 cannot be limited due to the insufficient length of the cable 200. Enough surplus is left to cable 200 between first spacing subassembly 1 and the spacing subassembly 2 of second, and first spacing subassembly 1 removes in the safe distance of reserving, and the radius of torsion is convenient for control, avoids cable 200 to lead to dragging the destruction because of first spacing subassembly 1 upwards removes.

The column in this embodiment is generally cylindrical. The axial direction of the tower barrel is the height direction of the tower barrel. As shown in fig. 2, a twisting platform 300 is provided inside the tower. The cable twisting platform 300 is circular as a whole, and the cable twisting platform 300 is fixed on the tower drum along the circumferential direction of the cable twisting platform 300. In this embodiment, the cable twisting platforms 300 are all fixedly connected to the inner wall of the tower in the circumferential direction.

In other alternative embodiments, the cable twisting platform 300 may be partially attached to the inner wall of the tower in the circumferential direction, rather than being fixedly attached to the inner wall of the tower around the entire circumference of the cable twisting platform 300. The cable twisting platform 300 is fixedly connected to the tower.

In the embodiment, the first limiting assembly 1 and the second limiting assembly 2 are respectively mounted on the cable twisting platform 300. The first limiting component 1 can slide up and down along the direction perpendicular to the cable twisting platform 300, and the second limiting component 2 is also arranged on the cable twisting platform 300.

In other embodiments, the first limiting assembly 1 can also be mounted on the cable twisting platform 300, and the second limiting assembly 2 is mounted on the inner wall of the tower; alternatively, the first limiting assembly 1 may be installed on the inner wall of the tower, and the second limiting assembly 2 may be installed on the cable twisting platform 300. Other embodiments are not described in detail herein.

As shown in fig. 10, in the present embodiment, the first limiting assembly 1 is disposed at the center of the cable twisting platform 300. Because the cable 200 above the first limiting component 1 can rock in the tower, the first limiting component 1 is arranged in the center of the cable twisting platform 300, and the possibility of collision between the cable 200 and the inner wall of the tower can be reduced as much as possible. The second limiting component 2 is arranged at the side part of the twisting platform 300. After the cable 200 passes through the cable twisting platform 300 from top to bottom at the first limiting component 1, the cable 200 passes through the cable twisting platform 300 from bottom to top at the second limiting component 2. At the second limiting component 2, the cable 200 is fixedly connected with the cable twisting platform 300 through the second limiting component 2, and the cable 200 is completely fixed at the second limiting component 2. In addition, the installation of the cable 200 at the cable twisting platform 300 also utilizes the space below the cable twisting platform 300, and reduces the risk of collision between the cable 200 and personnel and other equipment on the cable twisting platform 300.

In other embodiments, the first limiting component 1 may not be disposed at the center of the cable twisting platform 300, so as to ensure that a suitable distance is left between the first limiting component 1 and the inner wall of the tower, and the distance ensures that the cable 200 above the first limiting component 1 swings within a certain range and does not collide with the inner wall of the tower.

As shown in fig. 11, in this embodiment, the middle plate of the cable twisting platform 300 between the first limiting assembly 1 and the second limiting assembly 2 is detachable. When the cable 200 is installed, firstly, the cable 200 is dropped downwards along the axial direction of the tower, then the middle plate between the first limiting component 1 and the second limiting component 2 is removed, the position of the sliding component in the first limiting component 1 is moved, the sliding component is placed at the lowest position (namely, the first position) of the first limiting component 1, and after the cable 200 is determined to be the twisting lowest position, the cable 200 fixing device in the first limiting component 1 is used for fixing the cable 200. At this time, the first fixing portion of the cable 200 is fixed in the first position limiting assembly 1, and the remaining cable 200 is placed on the surface of the cable twisting platform 300. And (3) lowering a cable section between the first fixing part and the second fixing part of the cable 200 from the cable twisting hole exposed after the cable twisting platform 300 cover plate is detached, then fixing the second fixing part of the cable 200 on the cable fixing device of the second limiting component 2, and installing the first limiting component 1 and other parts on the second limiting component 2 to realize the fixation of the cable 200.

The plate between the first limiting component 1 and the second limiting component 2 on the cable twisting platform 300 can be detached, so that the cable twisting platform 300 is prevented from being repeatedly penetrated and arranged in the installation process of the cable 200, the lifting of the cable 200 in the installation process of the cable 200 by manpower is reduced, and the labor intensity in installation is reduced. In the process of installing the cable 200, the cable 200 is laid through the cable twisting platform 300 without installation of tools such as a ladder.

In other embodiments, the cable twisting platform 300 may be assembled from bars, so that the cable 200 may be directly laid down along the gaps between the bars without removing the plates during installation.

In this embodiment, the first limiting component 1 includes a first cable clamping member 11, and the first cable clamping member 11 is used for clamping the first fixing portion. The first cable clamping piece 11 can clamp cables 200 with different diameters, and after the first cable clamping piece 11 clamps the cables 200, the first cable clamping piece 11 can move up and down along with the cables 200 in the axial direction of the tower. The first cable clamp 11 is movable between a first position and a third position.

As shown in fig. 8, the first cable holding member 11 includes a first clamping plate 111 and a second clamping plate 112, and the first clamping plate 111 and the second clamping plate 112 are opposed to form a cable holding groove. In this embodiment, the first clamping plate 111 and the second clamping plate 112 are respectively provided with a semicircular groove, and the grooves of the first clamping plate 111 and the second clamping plate 112 are oppositely arranged. When the clamping device is used for clamping the cable 200, the cable 200 is clamped in the grooves on the first clamping plate 111 and the second clamping plate 112, and the fasteners on the first cable clamping part 11 are relatively screwed, so that the first clamping plate 111 and the second clamping plate 112 are relatively close to the clamping cable 200.

In other embodiments, a semicircular groove may be formed only on one side of the first clamping plate 111 or the second clamping plate 112, and the semicircular groove may also serve to clamp the cable 200. The first clamping plate 111 and the second clamping plate 112 are detachably connected, and the first clamping plate 111 and the second clamping plate 112 are connected in a locking manner through bolts and nuts.
