Definitions
- the invention relates to a component for producing a tower of a wind power plant with a boundary surface forming part of the outer surface of the tower and having a passage opening for receiving a door.
- Conventional wind turbines comprise a tower firmly anchored to the ground, a machine nacelle mounted on the top of the tower about a vertical axis of rotation and a rotor attached to the nacelle and having at least one rotor blade, which is rotatable about an essentially horizontal rotor axis.
- tower heights of 100 m or more and rotor diameters of at least 70 m are achieved.
- the tower which generally has a diameter of more than three meters, must be accessible from the inside, so that the parts requiring maintenance in the region of the rotor axis can be safely reached without great effort.
- the base of the tower which is usually made of rolled steel sheets and has a thickness of up to 40 mm, there is generally a door lock
- FIG. 2a shows a view of the lower part of this tower construction
- FIG. 2b shows a sectional view taken along the sectional plane A-A.
- reference number 10 denotes the tower, reference number 20 the through opening and reference number 12 the frame welded into the through opening.
- the through opening 20 it has been shown that weak points occur in particular in the area of the welded transition between the frame 12 and the adjacent surface of the tower 10.
- the through opening 20 it has already been proposed to produce the through opening 20 as an oval opening while avoiding sharp corners, as indicated in FIG. 2a.
- weak points in the area of the transition between the frame 12 and the adjacent lateral surface of the tower cannot be completely eliminated, so that the attachment of additional reinforcing elements and / or an increase in the material thickness of the steel sheets used for forming the lateral surface also occurs this measure is inevitable.
- the object of the invention is to provide a component of the type described at the outset. provide, which can be manufactured and assembled inexpensively while avoiding intolerable weak points in the tower construction.
- this problem is solved by a development of the known components, which is essentially characterized in that at least one area of the component having the through opening is at least partially made of a preferably weldable cast material, such as cast steel
- This invention is based on the knowledge that the weakening of the tower construction observed is primarily due to the welding process in the area of the through opening required for the production of conventional components of the type described at the outset, and this welding process can be avoided if the through opening is used using a Cast part is realized because such cast parts can be prefabricated by suitable choice of the mold so that the subsequent attachment of additional elements can be largely dispensed with.
- the use of components made entirely of a cast material is intended, which are connected to other components of the tower in the course of a pre-assembly and / or in the course of the final assembly.
- the component is already designed as a pre-assembled component with at least one steel sheet adjacent to the casting and preferably welded to it.
- the boundary surface of the component according to the invention expediently essentially has the shape of a circular cylinder surface, or a section thereof.
- the connection between a cast part and a steel sheet of a component according to the invention designed as a preassembled component is expediently made by a butt seam.
- a butt seam In view of the wall thickness of more than 10 mm of the steel sheets used for the production of conventional towers of wind power plants, it is usually necessary to obtain a sufficiently strong welded connection that the weld seam is formed in a wedge-shaped cross section formed between the casting and the steel sheet , In a joint of this type, a number of weld beads can be placed in succession, starting from the region of the smallest width, which finally fill the joint completely.
- the V-shaped chamfer required to form a joint of this type with a wedge-shaped cross section can be integrated into the cast part when the cast part is produced by using suitable components according to the invention.
- the through opening of components according to the invention also preferably has an essentially oval shape.
- further functional elements usually have to be provided in the area of the passage opening, such as the door frame for articulated fastening of a door leaf, fastening elements for fire extinguishers or the like, antenna holders, suction and / or exhaust pipes for an emergency power unit equipped with a diesel engine, a receptacle for a banister, an exit or a blow-out opening for the cooling or fresh air supply and / or a door lock.
- these functional elements are welded to the tower jacket. This creates additional weaknesses in the tower jacket.
- this problem can be solved in that at least one of the additional functional elements is cast as an integral part of the cast part.
- Fig. 1 is a sectional view of a component according to the invention.
- Fig. 2 shows the tower of a wind turbine according to the prior art.
- FIG. 1 shows a component according to the invention forming a through opening 20 of the type shown in FIG. 2.
- This component is a cast part made of cast steel and comprises a fastening element 32 for the articulated attachment of a door leaf, a door leaf stop 34 and a total of three fastening elements 36 which can be used as fire extinguisher holders, antenna holders and / or door security devices.
- the component shown in FIG. 2 has an outer boundary surface in the form of a section of a truncated cone surface. To assemble a tower of a wind turbine, this component is welded to other components formed in the form of rolled steel sheets in order to produce a tower for the wind turbine.
- the through opening is formed in the size of a conventional door (standard door).
- the invention is not limited to the exemplary embodiment explained with reference to the drawing.
- the use of components is also contemplated in which only a part of the through opening is delimited by the cast part and the rest of the through opening is delimited by a rolled steel sheet.
- the use of components according to the invention with circular cylindrical jacket-shaped and / or flat boundary surfaces is also contemplated. Further functional elements can also be provided on the casting of the component according to the invention.
