Description

Title: a transverse axis wind turbine and an assembly of a support structure and the transverse axis wind turbine
Description:
According to a first aspect, the present disclosure relates to a transverse axis wind turbine.
According to a second aspect, the present disclosure relates to an assembly comprising the transverse axis wind turbine according the first aspect of the present disclosure.
A transverse axis wind turbine is a type of wind turbine wherein the rotor axis is set transverse to the wind, but not necessarily vertically. Components of a known transverse axis wind turbine such as a generator and, if provided, a gearbox are located at the base of the transverse axis wind turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair.
An advantage of transverse axis wind turbines is that there is no need to point the rotor into the wind, which removes the need for wind-sensing and orientation mechanisms.
The transverse axis wind turbine according to the present disclosure is arranged for being connected to a support structure such as a building or a mast. The transverse axis wind turbine may for example be connected to a facade of the building.
The transverse axis wind turbine comprises: - a first connecting element arranged for connecting said transverse axis wind turbine to said support structure; - a second connecting element arranged for connecting said transverse axis wind turbine to said support structure; - a first rotor arranged to be propelled by air flow and provided with first rotor blades and a first rotor axis, and rotatably connected, via said first rotor axis, at a first side of said first rotor, to said first connecting element, and at a second side of said first rotor, opposite to said first side of said first rotor, to said second connecting element.
By providing the first connecting element and the second connecting element at opposite sides of the first rotor, a relatively robust wind turbine may be realised at relatively low cost while allowing a relatively large power output. The present disclosure relies at least partly on the insight that a known transverse axis wind turbine is supported, by a mast, only at a lower side of the wind turbine. Supporting the wind turbine only at one side may require a relatively robust and costly construction of the wind turbine and the mast to allow for a relatively large power output.
The first and second connecting elements provide for a relatively stable positioning of the first rotor relative to the support structure even for a relatively large first rotor when being propelled by a relatively strong wind. Maintaining the position of the first rotor relatively stable allows for a relatively safe operation of the wind turbine while avoiding or reducing the risk of undesired movements of the first rotor relative to a nominal position of the first rotor relative to the support structure.
Within the present context, undesired movements are to be understood as movements of the first rotor in a direction transverse to the rotor axis such as a bending of the rotor axis caused by the air flow acting on the first rotor.
In an embodiment of the transverse axis wind turbine according to the present invention, said transverse axis wind turbine further comprises: - a first electrical generator arranged for generating electricity, wherein said first rotor axis is coupled to said first electrical generator for generating said electricity upon rotation of said first rotor about said first rotor axis. Preferably, said first electrical generator is provided at a side of said first connecting element facing away from said first rotor.
Coupling the rotor axis to the electrical generator provides the benefit that the aerodynamic forces are translated to rotation of the generator thereby creating electricity.
In another embodiment of the transverse axis wind turbine according to the present invention, said transverse axis wind turbine further comprises: - a third connecting element arranged for further connecting said transverse axis wind turbine to said support structure; - a second rotor arranged to be propelled by air flow and provided with second rotor blades and a second rotor axis, and rotatably connected, via said second rotor axis, at a first side of said second rotor, to said second connecting element, and at a second side of said second rotor, opposite to said first side of said second rotor, to said third connecting element.
This arrangement provides the possibility that the second rotor can be positioned close to the first rotor in a relatively stable position. The second connecting element and third connecting element provide for a relatively stable positioning of the second rotor relative to the support structure even for a relatively large second rotor when being propelled by a relatively strong wind. Maintaining the position of the second rotor relatively stable allows for a relatively safe operation of the wind turbine while avoiding or reducing the risk of undesired movements of the second rotor relative to a nominal position of the second rotor relative to the support structure.
In another embodiment of the transverse axis wind turbine according to the present invention, said second rotor axis and said first rotor axis are connected to each other such that said second rotor axis is coupled, via said first rotor axis, to said first electrical generator for generating said electricity upon rotation of said second rotor about said second rotor axis.
Coupling said second rotor axis to the first rotor axis is beneficial for generating electricity using a first electrical generator capable of a relatively large output power.
Preferably, said second rotor axis and said first rotor axis are releasably connected via a first coupling element, preferably a resilient coupling element arranged for resiliently coupling said first rotor axis to said second rotor axis.
A benefit of releasably coupling the second rotor axis and the first rotor axis is that the second rotor can be easily decoupled (and removed) from the transverse axis wind turbine, for example for maintenance purposes.
In another embodiment of the transverse axis wind turbine according to the present invention, said transverse axis wind turbine further comprises: - a third rotor arranged to be propelled by air flow and provided with third rotor blades and a third rotor axis, and rotatably connected, via said third rotor axis, at a first side of said third rotor, to said first connecting element, and at a second side of said first rotor, opposite to said first side of said third rotor, to said second connecting element.
This arrangement provides the possibility that the third rotor can be positioned close to the first rotor in a relatively stable position. The first connecting element and second connecting element provide for a relatively stable positioning of the third rotor relative to the support structure even for a relatively large first rotor and/or third rotor when being propelled by a relatively strong wind. Maintaining the position of the third rotor relatively stable allows for a relatively safe operation of the wind turbine while avoiding or reducing the risk of undesired movements of the third rotor relative to a nominal position of the third rotor relative to the support structure.
In an embodiment of said transverse axis wind turbine wherein said support structure is formed by a mast, said transverse axis wind turbine is arranged for providing said third rotor and said first rotor at opposite sides of said mast.
Preferably, said transverse axis wind turbine further comprises: - a second electrical generator arranged for generating electricity, wherein said third rotor axis is coupled to said second electrical generator for generating said electricity upon rotation of said third rotor about said third rotor axis. Preferably, said second electrical generator is provided at a side of said first connecting element facing away from said third rotor.
Coupling the third rotor axis to the second electrical generator provides the benefit that the aerodynamic forces are translated to rotation of the second generator thereby creating electricity. 5 In another embodiment of the transverse axis wind turbine according to the present invention, said first connecting element and said second connecting element are spaced apart in the range of 3 meter to 15 meter, preferably are spaced apart in the range of 5 meter to 8 meter.
This allows for placing rotors in between the first connecting element and the second connecting element that may differ in length.
Preferably, a diameter of said first rotor, in a direction perpendicular to said rotor axis, is in the range of 3 meter to 15 meter, more preferably in the range of 5 meter to 8 meter.
The possibility of rotors having different diameters has the benefit that the transverse axis wind turbine can already be used at relatively low wind speeds.
In another embodiment of the transverse axis wind turbine according to the present invention, said transverse axis wind turbine comprises a fourth connecting element arranged for connecting said first electrical generator to said support structure.
The fourth connecting element provides for a relatively stable positioning of the first electrical generator relative to the support structure even for a relatively large first electrical generator. Maintaining the position of the first electrical generator relatively stable allows for a relatively safe operation of the wind turbine while avoiding or reducing the risk of undesired movements of the first electrical generator relative to a nominal position of the first electrical generator relative to the support structure.
In the assembly of the support structure, such as a building or a mast, and said transverse axis wind turbine according to the first aspect of the invention, said transverse axis wind turbine is connected to said support structure via said first connecting element and said second connecting element, preferably, said first rotor axis is vertical.
Preferably, said support structure is a mast having a height in the range of 50 meter to 300 meter, more preferably in the range of 200 meter to 300 meter.
The benefit of a high support structure is that more electricity can be generated, because at higher elevation, there is often more and stronger wind. In case there is a limit to the maximum height of the wind turbine, for example due to regional regulations, a support structure lower in height is also possible.
Embodiments of the transverse axis wind turbine and the assembly according to the present disclosure will next be explained by means of the accompanying schematic figures, wherein:
