Definitions

  • the present invention relates to a method for the production of wind turbine tower segments and a wind turbine tower assembled from tower segment produced by this method.
  • towers for wind turbines As steel towers. Those towers are constructed with tower segments. The tower segments are manufactured at a production site, which is remote from the wind turbine site.
  • US 2008 0256892 describes a wind energy tower with a load-bearing tower wall, which has a circulating outer periphery and consists of a plurality of wall sections, which each one have one centre section and two border section running in the longitudinal direction of the tower, which are provided with a plurality of connection bores, wherein the surface defined by the border sections run along the outer periphery or in a constant distance to the same, and the connection bores are aligned transversely to the outer periphery.
  • the aim of the invention is therefore to provide a method for the production of wind turbine towers that allows a quicker production that is less expensive and a wind turbine tower that is assembled quicker and less expensive.
  • the method for the production of tower segments comprises the steps to provide a sheet steel, to cut the sheet steel into a number of steel plates, to cut at least one opening in the number of steel plates and to bend the steel plates into a desired shape.
  • all steps necessary to achieve a tower segment of a wind turbine tower in the desired state of production can be performed.
  • individual treatment of each steel plate is possible.
  • steel plates of different shape can be produced in one process.
  • towers with differing dimensions and/or variations in the facilities can be assembled from these tower segments.
  • a wind turbine tower comprises the segments being manufactured according to the method invented.
  • the sheet steel is provided in a rolled manner from a coil.
  • the steel is cut in plates with the required length from a long strip of steel.
  • material is saved.
  • the sheet steel is provided as a precut sheet steel plate.
  • the width of the sheet steel has the dimension required.
  • there is less material cut away and left over. Thus material is saved.
  • the sheet steel is provided as pre-bent steel plate.
  • the plates are at least partially formed in the desired shape before fed into the production process. Thus time and machinery is saved in the production process.
  • the steps are performed in a production process.
  • the process requires a minimum of transporting lifting and handling of the steel plates.
  • the steps are performed in a continuous process.
  • the steel plates move from one step in the production to the next.
  • no transportation and/or storage is needed for the steel plates between the steps in the process.
  • storage space is saved and time and personnel to transport and store the steel plates is saved.
  • the steps are performed in a machine-based process.
  • no manual handling of the plates has to be done.
  • time and personnel is saved.
  • the additional step of performing a surface treatment on the steel plates is performed.
  • all steps that have to be performed to the plates to achieve steel plates in the right state to assemble the tower can be performed in one process. Thus no additional treatment is necessary.
  • the surface treatment is a sandblasting of the surface, a painting of the surface, a lacquering of the surface, a roughening of the surface, a pre-mounting of equipment, which needs to the connected with the surface, and/or cutting of threads into the surface.
  • the step of cutting the sheet steel into a number of steel plates is performed by mechanical cutting means, laser cutting means, plasma cutting means and/or flame cutting means.
  • the step of cutting the opening in the steel plates is performed by punching, drilling, laser cutting, plasma cutting, cut bolt-holes, door-openings and/or openings for ventilation or windows.
  • punching, drilling, laser cutting, plasma cutting, cut bolt-holes, door-openings and/or openings for ventilation or windows are all kind of openings, holes and/or cavities can be added to the steel plates.
  • an individual design for every single steel plate can be performed.
  • an additional processing step is performed for shaping the steel plate to achieve a different thickness or width.
  • a different size or thickness of the steel plates can be achieved in comparison to the sheet steel in the beginning of the process.
  • an individual thickness or width of the single steel plates can be achieved.
  • a number of bended steel plates are connected to assemble a ring-shaped tower element.
  • connection of the steel plates is done by using the openings for threaded or bolted connections.
  • no additional step to add connecting means is necessary.
  • FIG. 1 shows a production process for a wind turbine tower segment according to the invention
  • FIG. 2 shows a steel plate produced by the method claimed
  • FIG. 3 shows various shapes of steel plates produced by the method claimed.
  • FIG. 1 shows a production process for a wind turbine tower segment according to the invention.
  • the sheet steel 1 is provided in a rolled manner on a coil 2 .
  • the sheet steel 1 is unrolled and flattened out by the help of rollers 8 .
  • the sheet steel 1 is therefore moved forward by driving means 3 .
  • the coil 2 of sheet steel 1 is provided in the right width.
  • One example of such is a width of 2.07 m and with a steel plate thickness of 17.1 mm.
  • To get steel plates 9 with the desired length the sheet steel 1 from the coil 2 is cut by cutting means 4 .
  • the cutting means 4 are means for mechanical cutting, laser cutting, plasma cutting or flame cutting.
  • the steel plate 9 is processed by surface processing means 7 and rollers 5 .
  • the surface processing means 7 are e.g. means for sandblasting, painting, lacquering, pre-mounting, threads cutting or dimension measurement for quality ensurance.
  • the rollers 5 are processing means for shaping the steel plate 9 like rolling it, to achieve a different thickness or width, or to form it by bending.
  • the steel plate 9 is moved forward by driving means 3 .
  • the processing means 6 are processing means for punching, drilling, laser cutting or plasma cutting to cut holes, door-openings or openings for ventilation or windows.
  • FIG. 2 shows a steel plate 9 produced by the method claimed. After being processed the steel plate 9 show e.g. holes 10 cut into the steel plate 9 or a bend 11 to shape the steel plate 9 .
  • FIG. 3 shows various shapes of steel plates 9 produced by the method claimed.
  • the steel plate 9 After being processed the steel plate 9 might be shaped by being bent 12 to be prepared as a segment for poly-angular tower.
  • the steel plate might also be curved 13 to be prepared as a tower segment for a round or oval tower.
