Definitions

  • the invention relates to a tower for a wind turbine with at least one section having polygonally arranged walls, the walls being composed of wall sections, the wall sections being formed from a wood material, the wall sections being connected either to form segments which are arranged one above the other, or in a helical manner are arranged offset to one another, the wall sections having at least one front surface, at least one rear surface, and laterally at least four lateral surfaces in the form of at least one head surface, at least one base surface and at least two side surfaces.
  • a wind turbine is a device for generating electrical energy.
  • the wind turbine is provided with a foundation, a tower, which has a polygonal cross-section which narrows as the height increases, and which is erected on the foundation, and a nacelle which is placed on the tower.
  • the drive unit for generating energy which is connected to the rotor blades, is located on the nacelle.
  • Wind turbines of the type mentioned at the outset are known and familiar to those skilled in the art.
  • the nacelle is arranged on the tower of the wind turbine.
  • the gondola is in turn provided with a rotor with a horizontal or vertical axis of rotation, which is coupled to a generator.
  • the use of three-bladed rotors is common, as they ensure relatively smooth running.
  • Such Wndkraftanlagen are far developed in terms of the efficiency with which the power of the wind can be used.
  • the height of the towers of wind turbines vary. In general, the energy yield that can be achieved with the wind turbine correlates with the height of the tower, so that heights of over 100 m, even over 150 m, can be erected. There is an economic connection between the construction costs incurred and the yield from energy generation, whereby experience has shown that the construction costs incurred increase disproportionately with the overall height of the wind turbine.
  • the construction of the tower is aimed at the static loads acting on the tower through the nacelle and the dynamic loads acting due to the rotation of the rotary blades of the rotor and the possibility of movement of the nacelle depending on the direction of the wind.
  • Known towers are made of steel rings, concrete elements or wooden elements. From an economic point of view, it is desirable, as stated, to erect the height of the towers in an economically maximized manner, since the yield of a wind turbine depends on the hub height of the rotor and the yield increases as the height increases. At the same time, the greater height of the tower increases the demands placed on the statics and the material or the cost of materials in the tower. The wall thicknesses increase and this increases the effort required to erect the tower.
  • the bases of the known towers are either polygons or ring-shaped segments of a circle.
  • Polygonal towers made from individual segments of concrete are known from WO2003069099A1.
  • the erected elements are prestressed with prestressing strands.
  • the strands/tendons run over the entire length of the tower inside the tower.
  • embodiments are known in which the strands/tendons run inside the walls.
  • the strands/tendons can also be pressed.
  • towers for Wndkraftanlagen can be produced from wood, with which towers for Wndkraftanlagen can be created inexpensively, quickly and with material savings.
  • Such towers have been further developed in such a way that the towers are manufactured on site from individual components, which are each connected directly to the adjacent elements using connecting means (DE102009061027A1). Furthermore, one sees it Embodiment provides that inside the tower a falsework is erected that itself makes no contribution to the removal of the static or dynamic loads of the finished tower (DE102009048936A1). A coating from DE102009017586A1 is known as protection against environmental influences acting on the surface, in particular moisture.
  • the object of the invention is therefore to provide a tower for a wind turbine with improved connections between the wall sections and to reduce the costs of construction.
  • At least one lateral surface of a first wall section has at least one elongated channel extending into the interior of the wall section for receiving a connecting means, which in the at least one front surface and/or the at least one rear surface of a first wall section contains at least one engagement opening is provided, which is connected to the at least one channel, that at least one side surface of a second wall section has at least one elongate channel extending into the interior of the wall section for receiving a connecting means, which in the at least one front side surface and/or the at least one Rear surface of the first wall section is provided at least one engagement opening, which is connected to the at least one channel that the at least one channel of the first wall section with the at least one channel of the second Wandabsc hnitts are arranged to each other in the assembled state of the wall sections that there is a continuous channel.

  • a further teaching of the invention provides that the metal rod is at least long enough for the at least one counter element to be fitted onto the at least one threaded section in at least one engagement opening.
