Definitions

  • the invention relates to a tower for a wind turbine wherein the walls of the tower are at least partially made of individual wall sections which are interconnected via connecting means.
  • a wind turbine In a wind turbine is a device for generating electrical energy.
  • the wind turbine is provided with a foundation, a tower which is built on the foundation, and a gondola which is placed on the tower.
  • the drive unit At the nacelle is the drive unit connected to rotor blades for power generation.
  • the construction of the tower is geared to the static load generated by the nacelle on the tower and the dynamic loads generated by the rotation of the rotor's rotor blades and the possibility of the gondola moving depending on the wind direction.
  • Well-known towers are made of steel rings or concrete elements.
  • the bases of the known towers are either polygons or annular circle segments.
  • Polygonal towers, which are made of individual segments of concrete, are known from WO 2003/069099 A. Furthermore, it is known to erect such polygonal towers made of wood (DE 10 2007 006 652 A1).
  • a crucial aspect in towers, which are formed from segments arranged in sections, is that the horizontal
  • the object of the invention is therefore to provide a tower for a wind turbine, in which it is possible, taking into account the aforementioned shear force or shear stress problem, to increase the design height while saving material and / or to reduce manufacturing costs.
  • the object according to the invention is achieved in that the wall sections are arranged offset from one another to form a helix.
  • the thrust load / shear force is derived via the helix and there is no starting point for lifting the tower at a predetermined location. For this reason, wall thicknesses can be reduced and it is in particular possible to choose simpler and therefore cheaper connecting means.
  • the helix is a single helix or a multiple helix formed from a plurality of single helices.
  • the number of single helices forming the multiple helix coincides with the number of wall sections in a horizontal plane of the tower.
  • the wall sections are provided in the multiple helix as put on the top diamond.
  • the rhombus is provided as a circle segment or formed by two vertically interconnected triangles, wherein the surfaces of the triangles are arranged at an angle to each other, the 360 ° divided by the Number of single helices is.
  • the upper abutment sides of the individual components of a helix have a continuous line and / or a gradation. As a result, the load dissipation in the tower is improved.
  • the wall sections at least partially in the joints have slots which are arranged transversely to the impact direction and / or along the direction of impact.
  • the slots connecting means are used, which are preferably metal sheets, particularly preferably perforated sheets, which are preferably glued.
  • the butt holes can be taped with, for example, a tape or Plexiglas.
  • the introduction of the adhesive takes place by spraying the spaces between the component and the connecting element.
  • wooden parts or wooden dowels can be used if the components are wood elements. These fasteners are inexpensive elements, but provide the necessary strength in terms of thrust or thrust loads between the individual components.
  • a further teaching of the invention therefore provides that at least partially a coating is applied to the outer surface of the tower, wherein the coating is preferably applied such that the coating absorbs tensile loads acting on the outer surface of the tower, and that the coating seals the outer surface against environmental influences, in particular moisture, which act on the outside of the surface of the tower.
  • such a coating makes it possible to reduce the amount of steel required in terms of tensile loads, since the coating absorbs tensile loads while at the same time saving the coat of the steel elements.
  • concrete towers it is possible to reduce the concrete cover over the steel framework, so that a cost reduction arises.
  • wooden towers the coating makes it possible to use wood-based materials and their bonding agents which have only an approval for interior work.
  • the coating in the coated portion of the tower is applied over the entire surface, and the coated portion wrapped. It is advantageous that the coating is a laminate, a film, a fabric, a textile or a plate. Particularly preferred is a film, a plate, a fabric and / or textile made of plastic, with particular preference polypropylene, polyurethane, polyvinyl chloride, polyester, polycarbonate or polyethylene are used as materials. Such materials are able to absorb tensile stresses and at the same time provide a seal and thus a seal against the environmental influences acting on the surface of the tower.
  • such materials have lower basis weights than, for example, paints on the surface of the tower, so that this weight can be reduced in the construction in terms of static pressure load, whereby the tower construction can be made slimmer overall.
  • the cost of these materials for example, compared to paints are lower.
  • the coating is applied at different times of the tower direction.
  • the coating is applied after erection of the tower. This can be done from above or below.
  • the coating can be applied in sections during the erection of the tower or on the individual components before erection of the tower. If the coating is applied before erection of the tower, then it has proved to be advantageous to apply the coating on site to the construction site. This reduces the cost of the coating and at the same time it can be ensured that the coating is not damaged during the transport of the individual elements.
  • the individual sections of the coating are then connected to one another, wherein the bonding is particularly preferably carried out by gluing or welding of the joints.
  • the coating is applied directly to the components of the tower.
  • the application takes place over the entire surface by gluing.
  • a partial bonding can take place on a surface of a component. Bonding ensures that the static load is absorbed by the coating.
  • the tower is at least partially made of steel, concrete, in particular reinforced concrete, and / or wood or wood-based material.
  • the wood or wood-based material is cross-laminated timber and / or wood composites.
  • the coating in wood has a lower vapor permeability than the wood.
  • the diffusion is reversed, that is, that the vapor permeability of the tower is not greater towards the outside, but to the inside.
  • a heat generator is furthermore preferably arranged, which is preferably the power electronics of a wind power plant.
  • the heat is the output power loss of the power electronics.
  • the heat generation dissipates the moisture inside the tower to the top and moves the moisture from the wood towards the inside of the tower and also with dissipated. If the coating is damaged, the moisture is transported away to the inside. The moisture in the particles and minerals gradually closes the damage to the coating, while still ensuring that the moisture escapes inwards.
  • the support structure of the tower is at least partially constructed of materials that are not suitable for outdoor use. These are materials that have been approved for indoor use only in the construction of buildings. By applying the coating, it is possible to use such materials and also connecting means for the supporting structure of a tower for a wind turbine, because the coating ensures the state of the internal use of the materials.
