Abstract

A wind turbine installation comprises a tower 10 and a support structure 15 e.g. a monopile. At least one resilient means 5 is arranged such that it can support the weight of the tower 10 on the support structure 15. The resilient means may be a disc or helical spring, a hydraulic spring or steel rod spring or an elastic pad of e.g. neoprene or nylon and may be pre-tensioned. The tower may be concentrically overlap mounted on the support with or without a transition member with the resilient means in between and the join may be principally supported by a cement based grout 25 with the resilient means redundant in case of grout failure. The resilient element may be supported by a rod between pairs of brackets with resilient pads extending across lower bracket cut-outs to engage the top of the support and the bracket pairs may be spaced around the tower e.g. six at 60 degree intervals.

Description

Wind turbine support structure The present invention relates to a support structure for a wind turbine installation.
Wind turbine installations are often formed from a tower, on which a wind turbine rotor is mounted, and a support structure. The support structure usually consists of a mono pile. The tower and support structure are usually elongate and generally hollow, with a circular cross-section. The size of the cross section generally decreases towards the upper end of the wind turbine installation. The tower is usually bolted onto a transition piece, which is mounted concentrically around the upper end of the support structure.
The support structure and the transition piece are joined together by grouting.
Such grouting must support both the vertical weight force from the transition piece, the tower and its load, and must accommodate any bending moments acting on the tower and support structure. A bending moment may be caused by wind acting on the wind turbine installation. In the case of an offshore wind turbine, a bending moment could alternatively or additionally be caused by waves and/or current forces acting on the support structure.
One problem with such an arrangement is that there is no redundancy in the grouted connection: if the grout fails with respect to supporting its vertical load, the transition piece, and hence the tower, will slide down on the mono pile. Grout connections for mono pile wind turbine support structures have already been seen to have failed in several wind turbine installations in a single farm.
As mentioned above, wind turbine installations often comprise a tower bolted onto a transition piece. In the following, the term "tower" will be used to cover any form of tower-like structure for supporting a wind turbine, and includes a tower and its transition piece together.
According to a first aspect of the invention, there is provided a wind turbine installation comprising a tower and a support structure, and at least one resilient means, wherein, in use, the resilient means is arranged such that it can support the weight of the tower on the support structure.
By providing a resilient means that is capable of supporting the weight of the tower on the support structure, the wind turbine installation can have a simple, cheap and reliable support arrangement. The resilience of the resilient means can help to avoid high local forces which can be caused by moments on the tower and/or support structure bringing about a relative deflection between the tower and the support structure.
Preferably, the resilient means is mechanically connected, directly or indirectly, to the tower and/or the support structure. This can help to keep the resilient means in place. Alternatively, the resilient means may simply contact the tower and/or the support structure, but not actually be connected thereto. For example, the resilient means could just be located in a region between the tower and the support structure such that it can support the weight of the tower on the support structure, but not actually be connected to the tower and/or the support structure.
Such an arrangement may be simpler.
In use, the resilient means could be pre-tensioned or pre-compressed to support, at least partially, the vertical load from the tower. Indeed, the resilient means could be arranged to frilly support that load, such that any vertical support provided by grout is redundant. Alternatively, the resilient means could be arranged to support the vertical load from the tower only if or when a further supporting means (e.g. grout) fails in providing vertical support for the tower on the support structure.
The tower may be formed of an elongate hollow structure with inner and outer surfaces. The resilient means may be connected to the inner or outer surface of the tower (including a surface of a transition piece of the tower). Thus, this supporting arrangement can be provided either inside or outside the tower.
The resilient means may be arranged to rest freely on the support structure.
It is thus not necessarily required that the resilient means is fixed to the support structure.
Alternatively, the resilient means may be arranged to rest on the support structure and be connected thereto. This could help to prevent relative movement between the resilient means and the support structure.
The resilient means is preferably connected to the tower via a support. The support could comprise one or more brackets or the like and can provide a means for transferring the vertical weight force of the tower through the resilient means onto the support structure. The support could be made of steel. The support could be attached to the tower by any suitable means such as welding or using bolts.
The tower is preferably located partially inside or partially outside the support structure (e.g. using the known concentric arrangement described above).
Thus, the tower and the support structure may overlap one another, thereby providing means for resisting any bending moments acting on the installation.
Preferably the tower and the support structure overlap by a distance approximately equal to or greater than the diameter of the tower.
The tower and the support structure are preferably joined by grout. This could be provided in an overlapping region between the tower and the support structure, for example. The grout could be formed of a cement-based product, for example. The grout can help withstand moments acting on the tower and the support structure as well as providing some vertical support. In such an arrangement, there is thus a redundancy in the vertical support of the tower so that if the grout fails, the tower can still be supported by the resilient means. Furthermore, if the grout fails in its vertical support, it can still provide support against moments acting on the tower andlor support structure. In addition, by grouting the tower and the support structure together, this provides a relatively easy way to adjust the angle between the axes of the tower and the support structure and ensure that they are aligned.
Preferably. a plurality of resilient means are provided. These are preferably provided at equal angular spacings around the tower. For example, six resilient means could be provided at 60° spacings around the tower.
Any suitable resilient means could be used. The or each resilient means may comprise a spring; it may comprise at least one of a disc spring, a coil spring, a hydraulic spring and a rod spring, for example. The disc, coil and/or rod springs could be made of steel, for example. It may also comprise an elastic member, such as an elastic pad. The elastic pad could comprise neoprene and/or nylon. Such materials are suitably elastic and relatively durable.
It will be seen that, viewed from a further aspect, the invention provides a wind turbine comprising a tower which is resiliently mounted on a support structure.
The tower may be directly mounted on the support structure, or there may be a transition member, as discussed above. Preferably, the resilient mounting comprises one or more resilient means, as discussed above. The resilient mounting may be arranged such that it can support some or all of the vertical weight of the tower, as discussed above.
The present invention also relates to a support arrangement for supporting a tower on a support structure in a wind turbine installation, the support arrangement comprising at least one resilient means, wherein, in use, the resilient means is arranged such that it can support the' weight of the tower on the support structure.
Preferably, the resilient means is mechanically connectable, directly or indirectly, to the tower andlor the support structure.
The tower may be formed of an elongate hollow structure with inner and outer surfaces. The resilient means may be connectable to the inner or outer surface of the tower.
The resilient means may be arranged to be able to rest freely on the support structure.
The resilient means may be arranged to be able to rest on the support structure and to be connectable thereto.
The support arrangement may comprise a support to which the resilient means is connected, wherein the support is connectable to the tower. The support could comprise one or more brackets or the like.
Any suitable resilient means could be used. The resilient means may comprise a spring. It may comprise at least one of a disc spring, a helical spring, a hydraulic spring and a rod spring. The disc, coil andlor rod springs could be made of steel, for example. It may also comprise an elastic member such as an elastic pad.
The elastic pad may comprise neoprene and/or nylon or any suitable elastomeric material.
The support arrangement could be retrofitted onto existing wind turbine installations. Thus, viewed from a further aspect the invention provides a kit for providing resilient support to the tower of a wind turbine, the kit comprising one or a plurality of resilient means (preferably as described above) for supporting the weight of the tower of a wind turbine against the tower support, in combination with means for mounting the resilient means to the wind turbine structure such that vertical forces may be transmitted from the tower to its support structure.
Viewed from another aspect, the present invention relates to a method of manufacturing a wind turbine installation comprising providing a tower, a support structure, and at least one resilient means, and arranging the resilient means such that it can support the weight of the tower on the support structure. The wind turbine installation may be provided with further features as discussed above.
Viewed from another aspect, the present invention relates to a method of manufacturing a support arrangement for supporting a tower on a support structure in a wind turbine installation, the method comprising providing at least one resilient means, and arranging the resilient means such that, in use, the resilient means can support the weight of the tower on the support structure. The support arrangement may have further features as discussed above.
The support arrangement of the present invention is not limited to use in wind turbine installations and may have various other uses. The support arrangement could be arranged to support any structure mounted on a support structure, particularly on a mono pile support structure. For example, the support arrangement could be used to support a control and/or transformer station (e.g. in a wind turbine farm) on a mono pile support structure.
Thus, viewed from another aspect, the present invention relates to an installation comprising a mounting part and a support structure, and at least one resilient means, wherein, in use, the resilient means is arranged such that it can support the weight of the mounting part on the support structure.
Viewed from another aspect, the present invention relates to a support arrangement for supporting a mounting part on a support structure, the support arrangement comprising at least one resilient means, wherein, in use, the resilient means is arranged such that it can support the weight of the mounting part on the support structure.
In either of both of the previous two aspects, the support structure may be a mono pile support structure and/or the mounting part could be a control andlor transformer station, for example. The installation and support arrangement could have any further features as mentioned above in relation to other aspects of the invention.
Preferred embodiments of the invention will now be described by way of example only with reference to the accompanying drawings in which: Fig. 1 shows a schematic cross-sectional view of an embodiment of a wind turbine installation; Fig. 2 shows an enlarged schematic cross-sectional view of part of the wind turbine installation of Fig. 1 where the tower connects to the support structure; Fig. 3 shows a schematic cross-sectional view of part of another embodiment of a wind turbine installation where the tower connects to the support structure; and Fig. 4 shows a perspective view of an embodiment of a support arrangement inside a wind turbine tower and support structure.
Fig. 1 shows a wind turbine installation 10 with a tower 10 arranged over a support structure 15. A nacelle 35 is mounted on the top of the tower 10 and carries the rotor 40. The tower 10 is formed of a lower transition piece lOb and an upper tower piece 1 Oa, which are bolted together. The support structure 15 is formed of a mono pile.
The top of the support structure 15 extends into the bottom of the tower 10.
An annular region defined between the overlapping parts of the support structure 15 and the tower 10 is filled with grout 25 to join the support structure 15 to the tower 10. The grout 25 is a cement based product.
Supports 20 are attached to the inside of the tower 10 just above the top of the support structure 15. Springs 5 are connected to the supports 20 and rest on top of the support structure 15.
Fig. 2 shows this support arrangement in more detail. In this embodiment, helical coil springs are used. The springs 5 are provided at diametrically opposed positions across the diameter of the tower 10.
Fig. 3 shows an alternative embodiment where the supports 20 are formed of triangular brackets. Instead of the springs used in the embodiment of Figs. 1 and 2, in this embodiment are elastic pads 5 made of nylon are used.
Fig. 4 shows an alternative support viewed in perspective from inside the tower 10. This support is formed from two brackets 50 spaced apart by a bar 52.
The brackets 50 are attached along their sides to the inside of the tower 10. The bar 52 is located towards an upper end of the brackets 50.
At the lower end of the brackets 50, are cut-out notches 58. These notches 58 are arranged to extend over the top edge of the support structure 15.
An elastic pad 5, sits between the brackets 50 and is coupled to them via the bar 52. The elastic pad 5 rests on a top edge of the support structure 15.
In this embodiment, six such pairs of brackets 50 are provided at 60° intervals around the inside of the tower 10.
In use, in any of the embodiments shown, the resilient means 5 are pre-tensioned or pre-compressed to support the weight of the tower 10 (and its load comprising the nacelle 35 and rotor 40) on the support structure 15. The grout 25 supports the tower 10 and support structure 15 against any moments acting thereon.
The grout 25 also provides some vertical support against the weight of the tower 10.
If or when the grout 25 fails (e.g. by cracking), the resilient means 5 support the entire weight of the tower 10. In this case, even though the grout 25 is no longer providing any vertical support, providing it has not dropped out of the gap between the tower 10 and the support structure 15, it still provides support against any moments acting on the tower 10 and the support structure 15.
Various modifications will be apparent to those skilled in the art.
For example, instead of the support structure 15 extending into the tower 10, the tower 10 could extend into the support structure 15. The springs or elastic pads and supports 20 would then be provided on the outside of the tower 10.
In another embodiment, the grout 25 is not used. Rather, resilient pads are provided between the tower 10 and the support structure 15 in the overlapping region.
In another embodiment, the resilient means 5 are not pre-tensioned or pre-compressed. Rather, they are arranged to only support the weight of the tower 10 if or when the grout 25 fails in providing vertical support.
In other embodiments, rather than the helical coil springs used in the embodiment of Figs. 1 and 2, or the elastic pads of Figs. 3 and 4, a disc spring, a coil spring, a hydraulic spring or a steel rod spring is used.
In other embodiments, instead of several separate springs or elastic pads 5 provided around the inside of the tower 10, a single spring member or elastic pad is provided. In one embodiment this extends across the diameter of the tower 10 to rest on both sides of the support structure 15. In another embodiment, it extends as a ring around the top of the support structure 15.
In this application, the term "wind turbine installation" covers all kinds of wind turbine installations including land-based and offshore wind turbines.
