Definitions

  • the present invention relates to a frame for a rear part of a nacelle for a wind turbine.
  • the invention also relates to hatch means for shuttering an aperture in a bottom rear part of a nacelle for a wind turbine.
  • Wind turbines are equipped with a plurality of mechanical and electric components situated in the nacelle of the wind turbine. Initially, once the wind turbine is erected, these components have to be hoisted to the nacelle. However, subsequently during some time of functioning of the wind turbine, there may be a need for repairing these components.
  • Repair of the components may require lowering the components down to the ground or, in case the wind turbine is erected at sea, to a boat at the sea. It may even be necessary to exchange worn-out components with new component by initially lowering the worn-out components down from and subsequently hoisting new component up to the nacelle.
  • the components When components are to be installed in or removed from the nacelle, once the wind turbine is already erected, then the components may enter the nacelle through an aperture in the bottom of a rear part of the nacelle. However, when the wind turbine is functioning, the bottom of the nacelle must be closed. Accordingly, the bottom of the nacelle is provided with a hinged hatch, said hatch being capable of swinging downwards in order to reveal the aperture in the bottom of the nacelle, and through which aperture the components may be hoisted up into the nacelle or lowered down from the nacelle, when the hatch is open.
  • the size of the hatch is designed to be as small as possible, however of course in respect of the size of the components which are to be installed or which may need repair or exchange during use of the wind turbine.
  • the size of the hatch is chosen in accordance with the largest of the components being installed or that largest of the components being expected to be repaired at ground or having to be exchanged some time during functioning of the wind turbine.
  • the larger the hatch is the greater is the risk of the hatch being torn off or in any other way impeding the durability and security precautions of the wind turbine, when having to open the hatch during repair, installation or exchange of components, perhaps in rough weather conditions or in other circumstances such as wind turbines erected at sea, and where working at the wind turbine is especially difficult.
  • the person skilled in the art will construct the size of the hatch as being as small as possible taking into consideration the needs and demands mentioned above.
  • the size of the hatch is a compromise between a proper large size for installing and removing components in the nacelle and a proper small size for ensuring that the hatch does not introduce constructional weakness and safety hazard when being open.
  • a frame for a nacelle of a wind turbine said frame constituting a bottom rear part of the nacelle and being mounted to a bed-plate of the nacelle, said frame comprising two girders running from the bed-plate of the nacelle and rearwards, said two girders running along a bottom and along outer side edges of the rear part of the nacelle, and said frame having an aperture being established between the girders, and said aperture having a width being substantially the same as a width of the bottom of the nacelle, and said frame comprising a plurality of hatch means being sufficient to shutter the entire width of the aperture.
  • each part of the plurality of hatch means can be much more limited than prior art hatches.
  • This solution is not evident, because it is not obvious to a person skilled in the art how to have more than one or at the most two hatches.
  • the skilled person will not be able to envisage the provision of more than two hatches, because to the skilled person the hatches must be hinged to the nacelle. Hinging of one or two hatches can only be accomplished by hinging the one or at the most two hatches to the one or to both sides of the nacelle.
  • the aperture is capable of being closed by the plurality of hatch means, which are either fixedly attached to and permanently secured to the frame, or which are loosely detached and dismountably supported by the frame.
  • the hatch means which are connected to the frame by means of hinges or which are only supported by the frame.
  • the hatch means In order to maximise the size of the aperture, the hatch means must be constituted by a plurality of hatch means so that the size of the hatch means are limited, independently of whether the firstly mentioned solution or the secondly mentioned solution is chosen.
  • the object of the invention may also be obtained independently of the frame according to the invention by providing hatch means for an aperture in the rear bottom part of a nacelle of a wind turbine, said hatch means being constituted by readily detachable hatch means being supported by the nacelle, said hatch means being divided into a plurality of partial hatch means so that the hatch means is capable of being only partly removed to reveal only a part of the aperture.
  • Hatch means only being supported and not actually fixed to the nacelle will enable sizing and constructing the hatch means in any suitable manner not being limited to any fixing of the hatch means to the nacelle, and only being dependent on the need for shuttering the aperture and being dependent on the demands set by the security precautions.
  • the hatch means are constituted by a number of plates, said plates being supported by a frame of the nacelle at opposite sides of the plates, and a centre part of the plates closing the aperture, when the plates are being supported by the frame of the nacelle.
  • the hatch means may have a size and extension resulting in the hatch means being plates rather than shutters. Then, opposite sides of a pair of sides of the plates are supported by the frame of the nacelle, and the other pair of opposite sides extend across the aperture. In a preferred embodiment, the plates are not fixedly attached to the frame of the nacelle, the plates are also readily detachable.
  • the hatch means are constituted by plates, and if the plates have a length of one pair of opposite sides of the plates and a length of another pair of opposite sides of the plates being of an equal size, alternatively being of a substantially equal size, then the plates may be provided with means for grabbing the plates.
  • the plates may be of a size making the plates less suitable for handling. If so, the plates may be provided with grabbing means making it easier to handle the plates, The grabbing means may be handles attached to the plates in any suitable manner at any suitable place.
  • the grabbing means may also be holes or recesses provided in the plate itself and having a size and shape making the holes or recesses suitable as hand grips provided in the material of plate itself.
  • the object of the invention may, alternatively, also be obtained independently of the frame according to the invention by providing hatch means for an aperture in the rear bottom part of a nacelle of a wind turbine, said hatch means being constituted by fixedly attached means being permanently secured to the nacelle, said hatch means being divided into a plurality of partial hatch means, said partial hatch means being mutually hinged and foldable along the hinges, so that the hatch means are capable of being only partly folded to reveal only a part of the aperture.
  • Hatch means actually being fixed to the nacelle, but being constituted by a plurality of partial hatch means, will enable sizing and constructing the hatch means in a manner not being limited to only one or at the most two hatches having to shutter the aperture, and only being dependent on the need for shuttering only a limited part of the aperture being dependent on the demands set by the security precautions.
  • the partial hatch means are being mutually hinged by providing at least one boundary hinge at a border of the entire number of hatch means, said boundary hinge being secured to the frame of the nacelle, and by providing at least one intermediate hinge at a centre part of the entire number of hatch means, said intermediate hinge being provided between neighbouring partial hatch means.
  • a plurality of hatch means being fixedly attached to the frame of the nacelle, but also maintaining the capability of revealing the aperture, is preferably mutually hinged. At least the one outer partial hatch means is hinged via a boundary hinge to the frame of the nacelle, and the other partial hatch means are individually hinged via intermediate hinges extending parallel with the boundary hinge. Thereby, the entire plurality of hatch means constitute a louvered closing, where the number of partial hatch means and accordingly the number of hinges may be chosen arbitrarily.
  • the folding of the hatch means may then take place in different ways depending on whether the hinges run longitudinally to or transversely to the nacelle.
  • the folding of the mutually hinged hatch means may be effected transversely in relation to the nacelle by providing partial hatch means and intermediate hinges running longitudinally in relation to the nacelle, and where the folding of the mutually hinged hatch means is being effected by folding the partial hatch means partly or fully towards the rearmost end of the nacelle, alternatively by folding the partial hatch means partly or fully towards a position of the nacelle, where the nacelle meets the tower.
  • the folding of the mutually hinged hatch means may be effected longitudinally in relation to the nacelle by providing partial hatch means and hinges running transversely in relation to the nacelle, and where the folding of the mutually hinged hatch means is being effected by folding the partial hatch means partly or fully towards the one side of the nacelle, alternatively by simultaneously folding two individual sections of the partial hatch means partly or fully towards both sides of the nacelle.
  • the hatch means may constitute not only closure means, but may alo constitute part of the overall structural integrity of the nacelle, i.e. constituting parts adding to the structural rigidity and strength of the nacelle.
  • This aspect results in that the rigidity and the strength of the nacelle structure may be more or less decreased, when removing one or more of the hatch means.
  • This of course is non- advantageous.
  • the inventor has recognised that, when one or more of the hatch means are removed, the wind turbine is not operating, and thus the forces acting on the structural parts of the nacelle are limited compared to when the wind turbine is operating.
  • the teaching of the person skilled in the art says that if the hatch means constitute part of the structural integrity of the nacelle, which they may and preferably do, then the structural integrity of the nacelle will fail, when one or more of the hatch means are removed, and the nacelle will collapse.
  • the hatch means according to the present invention will decrease the structural integrity of the nacelle in such a manner that the hatch means are not a possible solution to the problem of providing an opening in the nacelle being as large as possible.

  • the aperture 3 extends substantially all the way from a rearmost end 5 of the nacelle to a bed-plate 6, where the nacelle 1 is connected to the tower 2 through the yaw mechanism (not shown).
  • the aperture 3 extends over substantially the entire extension of the bottom of the rear part 4 of the nacelle.
  • the length L of the aperture 3 is equal to a distance from the rearmost end 5 of the nacelle to the bed-plate 6, and the width W of the aperture is a distance between opposite sides of the aperture along sides 7,8 of the bottom of the rear part 4 of the nacelle. This results in the aperture 3 having its substantially largest possible size, when the aperture is provided at the bottom of the rear part of the nacelle.
  • the aperture 3 is substantially rectangularly shaped. However, it will be possible to give the aperture other shapes such as an oval or circular shape. Across the width W of the aperture, a carrying beam 9 is provided.
  • This beam 9 is intended for assisting in carrying components in the rear part 4 of the nacelle 1, such as the generator 10 or any other components situated in or extending into the rear part of the nacelle.
  • the beam 9 limits the overall free open size of the aperture, when the beam is mounted in the nacelle. However, the beam 9 might not be mounted until large components have been hoisted to the nacelle. Also, the beam 9 may be dismounted before large components are lowered down for repair or for being exchanged with other similar large components.

Abstract

La présente invention concerne un châssis pour nacelle d'éolienne, se plaçant à l'arrière du fond de la nacelle. L'invention concerne également un ensemble panneau d'accès fermant un regard de l'arrière du fond de la nacelle d'éolienne. Cet ensemble panneau d'accès, qui est construit de façon à se déposer facilement, est constitué d'une pluralité d'éléments de panneau. On peut ainsi ne déposer qu'une partie des éléments pour ne dégager que partiellement le regard. Cela fait qu'on peut n'ouvrir qu'une partie du regard dans le fond de l'arrière de la nacelle pour y faire passer des équipements de petites dimensions. Selon un mode de réalisation préféré, l'ensemble panneau d'accès est constitué d'une pluralité de tabliers. Ainsi, lorsqu'on dépose l'ensemble panneau d'accès, contrairement à ce qui se produit dans l'état actuel de la technique, l'ensemble panneau d'accès de l'invention n'offre plus de prise au vent.
