Definitions

  • the present invention relates to a reinforcing base for wind tower shafts, which may be made of concrete and / or steel.
  • the object of the invention is to achieve an efficient and optimized solution for the lower part of the shaft corresponding to a wind tower, specifically at its junction with the foundation, so that said shaft can be constructed as if it were of a lower height and reinforce it with the basement of the invention, which is arranged externally, that is to say where it suffers greater efforts.
  • the electricity produced by the wind turbines is based on the vertical wind profile curve, in which the wind speed is established based on the height and
  • the wind turbine transforms a part of the energy that carries the volume of air that passes through the surface beaten by the blades, when it circulates at a speed above the threshold, below which, the blades do not move.
  • the vertical wind profile has a variation of the parabolic slope, so that from a certain speed, the increase in wind speed with height is irrelevant. That is why, the dimensions of the blades and, consequently, the height of the wind turbine hubs, will not increase unlimitedly but that its roof has already been reached or is close to being reached, since an increase in the height means a significant increase in manufacturing, assembly and operation costs. To date, the realization of steel shafts was common, due to their good fatigue behavior, their lightness and the great development of the industrial manufacturing, transportation and assembly process.
  • Wind turbine assembly was also started in shallow continental shelf areas, especially in the North Sea, which also increased interest in concrete shafts due to durability due to the saline attack of seawater.
  • precast concrete parts accelerates the assembly process, ensures an adequate geometry of the pieces and has a high quality of concrete. It also favors the production process, reducing costs and achieving an industrialization of the production of shafts, complicated to achieve by manufacturing on site, in each location where the wind farm is located.
  • the patent ES 229653 also owned by Gamesa Innovation and Technology S.L, proposes a truncated conical solution for the shaft and made with precast concrete elements, joined in work.
  • the shaft is divided into circumference segments joined together.
  • This solution differs from the proposal since, although it is also made with precast concrete elements, the shaft section is conical and not cylindrical, and does not have the outer reinforcements that the proposed shaft has. Nor do they coincide in the methods of joining the pieces.
  • Patent DE 19832921 owned by W. Bernhardt proposes a mixed concrete-steel solution, by means of a hollow section of steel, which is subsequently filled with concrete, forming a composite section Steel-Concrete-Steel.
  • the correct union between the materials is achieved with bolts inside the hole, attached to both walls, so that there is a solid union between the three sections, since when the hole is concreted, the heads of the bolts are embedded in the solid .
  • Patent DE 29809541 owned by R. Beyer, also exposes a concrete shaft, consisting of sectors that are assembled, forming a truncated conical section, a solution that is markedly far from the proposed geometry.
  • Patent DE 102004048365 owned by O. Schneider, proposes a cylindrical shaft with annular outer reinforcements attached to the shaft, punctually with nickel-chrome pieces by screws. This typology is markedly far from that recommended, since the proposed stiffening ribs are joined by teeth in the tower body.
  • Patent DE 202007003842 owned by Boehmert & Boehmert, proposes a pyramid-shaped shaft, composed of cylindrical sections and straight sections linked together, forming a complete and closed shaft. This solution, again disagrees with the one proposed because it has a variable section and has no stiffeners.
  • Patent DE 202008001606 owned by P.Wetzel, proposes a truncated pyramid shaft, with sharp edges, and formed by straight panels without ribs. This solution strongly disagrees with the proposal, in the geometry of the section and in the absence of external reinforcements.
  • EP 2182209 owned by Martin Johnson, proposes a hybrid solution with the upper metal area and the lower concrete area, with a conical and prestressed section seen on the inner face. This solution continues to extrapolate the truncated conical solution from steel to concrete, adding the prestress seen as a tie element between the sections. There are no similarities with the recommended solution.
  • JP 2000283019 patent proposes a truncated conical spindle solution, consisting of superimposed concentric truncated conical caps, with shear keys in the support and with sleeve-type joints between the joint pieces.
  • This solution continues with the truncated conical section and with the truncated conical tubes described in other previous patents, with the difference that the joints reflected in the drawing are considered insufficient and a great difference can be seen with respect to the presented model.
  • the JP2004011210 patent owned by Fuji Corporation, proposes a succession of cylinders of circular or polygonal section, and of ascending diameter from the head to the base, joined with tongue and groove and with longitudinal and circumferential prestressing. These cylinders will eventually be divided into vertical sectors.
  • This patent takes the solution of cylindrical sections, in order to facilitate the manufacture, however, the lack of reinforcements forces to take a considerable diameter in the base, higher than the estimated one with the reinforcements in the presented model.
  • the JP2005180082 patent proposes a shaft with cylindrical section in several sections, its diameter being different in each section, with a maximum value in the recess with the foundation and a minimum in the union with the gondola. It also has the use of a special piece, to make the transition from one diameter to another, and the union between modules is done with prestressing seen from the inside of the shaft. Again, the detailed solution is based on the superimposed cylindrical rings to form each subsection of the shaft, and anticipates that the cylindrical section is a good solution to reduce costs, but nevertheless, it is notably far from the solution recommended with radial reinforcements in the lower zone.
  • the JP2005220715 patent proposes an initial solution at the base of a truncated conical section and a final section of cylindrical section. Each of the sections divides them into cone or cylinder trunks, composed of subsections joined together by means of horizontal and vertical screwed tongue and groove, as if it were a metallic joint. This solution differs markedly from the proposed geometry.
  • the JP2005248687 patent proposes a shaft solution built in situ, a solution markedly different from that recommended with precast concrete parts.
  • the JP2005330675 patent proposes a cylindrical shaft formed by superimposed sections and assembled by means of prestressing. In addition, how much with an energy absorption system in case of earthquake, based on metal parts that absorb part of the energy of the earthquake by hysteresis. This solution considers that the cylindrical section is the solution to the problem but does not consider the reinforcements at the base of the recommended solution.
  • the JP2007046292 patent proposes a truncated conical spindle solution, consisting of one-piece truncated conical cylinders, in the upper zone, and cylinders composed of conical sectors, in the lower zone.
  • the assembly between the sections is carried out with some tubes on hold, so that the section of the tubes in the upper part of the piece is larger than that of the lower part, constituting the joint by means of tongue and groove between the tubes.
  • the sections are provided with an inner circumferential rib to which a circumferential prestress will also be supplemented.
  • This solution is based on the tongue and groove joint between modules through the tubes, lacks reinforcement in the base and the section is helped by the joining tubes, to obtain greater rigidity, so the differences with the recommended solution are large.
  • the JP2008101363 patent proposes a shaft solution divided into several prismatic sections, each of which is divided into several vertical panels. These panels will have a part of their armor seen, bars that would be joined together by executing the filling of the joint with a mortar and mechanical anchors.
  • the JP2002122066 patent proposes a cylindrical section shaft throughout the section, with radial reinforcements in the lower area. This solution divides the shaft into several cylindrical prisms that are subsequently joined by a longitudinal post-tensioning. In the lower part, reinforcements are placed in the form of "T", attached to the foundation by post-tensioning and attached to the shaft, with bolts.
  • This solution also adopts the cylindrical shaft as an optimal solution, providing it with external reinforcement pieces in the base that help transmit the loads to the foundation.
  • the geometry differs from that recommended in this patent, in the following aspects: a.
  • the reinforcements are external parts attached to the shaft in all suialtura, unlike the solution that is recommended, where the external reinforcement parts are semi-exempt, that is, they only join the shaft discontinuously, providing effective reinforcements with less material.
  • the reinforcements have a "T" shaped section contrary to what is proposed in the patent application, in which the reinforcements will have a rectangular or trapezoidal section, but never in "T”.
  • the reinforcements are screwed to the shaft only by the outer face of the latter, this union being made with radial anchors to the longitudinal axis of the shaft, such anchors being prestressed, either with bolts, bar or cable.
  • the reinforcements are attached to the shaft by means of teeth that are assembled in recesses left for this purpose in the section of the shaft.
  • the reinforcements do not have longitudinal prestressing but only carry it transverse for attachment to the shaft, unlike the proposed solution, in which the stiffening or reinforcing ribs have prestressing tendons throughout their length.
  • All sections of the shaft are the same, unlike in the proposed solution in which there is a notably more rigid special piece, whose function is to anchor the longitudinal prestresses of the head reinforcement ribs.
  • US 7464512 proposes a metal shaft solution composed of several sectors that, when joined together, create the entire section. This proposal divides the shaft into several longitudinal sections, each of which is subdivided into several polygonal geometry caps. Each of these metal sectors, covers an angle between 90 and 120 degrees and has a polygonal section with a fold at each end, in which the union is made by means of thymes with the adjacent pieces. Eventually reinforcements will be placed inside the shaft in order to stiffen the joints. Although it is not specified in the text, a tripod geometry can be seen in the drawings in the base area, to bracing the shaft at mid-height.
  • WO 0201025 proposes a trunk conical concrete shaft with longitudinal prestressing, anchored in the foundation and made in situ.
  • WO 0204766 proposes a pre-fabricated concrete truncated conical shaft, formed by sections of identical height and variable edge, joined together by means of prestressing. longitudinal.
  • Another variant of the previous solution consists in breaking these edge alignments, placing the rotated sections at a certain angle, thus avoiding the formation of constant edges along the alignment.
  • This patent also indicates a cylindrical shaft solution, divided into vertical sections, each of which is divided into 8 cylinder sectors, assembled together.
  • the creation of constant joints along the shaft is avoided, placing each section to the stallion, avoiding the coincidence of the vertical joints in adjacent sections.
  • the shaft solution formed by a succession of cylindrical sections with specific section reductions is considered, maintaining the same exploded view as in the constant cylindrical solution.
  • WO 2007025947 patent proposes a shaft in situ, with concreting by pump with vertical upward flow. With this system, the different sections into which the shaft has been divided are successively concreted, causing the set parts to rise due to concrete pressure. In addition, it is essential to tighten the head of the built shaft, to avoid bending that could collapse the shaft during the concreting phase or elevation in each inferred.
  • a geometry in itself is not defined, but rather a method of making spindles for wind turbines in situ, which is clearly far from the recommended solution.
  • WO 20100.32075 patent proposes a shaft of mixed pyramidal section, concrete - steel.
  • This solution creates an open shaft, in which the section takes the form of a tetrahedron, in which the rising edges are circular sectors of concrete and these are braced together, with a lattice in each of the planes that form the pyramid.
  • a lighter section is achieved, which takes advantage of the total edge of the section, but which is more complex in its assembly and design, since although the concrete pieces are all the same in the entire height of the shaft, the lattices are Variable edge from the base to the head.
  • WO 2010044380 proposes different solutions that will be analyzed in detail.
  • the development of the patent begins, describing a solution of prismatic shaft of octagonal section and constant edge.
  • This shaft thus defined, would be divided, longitudinally, into rings of a certain height, and in turn, each ring would consist of 4 "C" shaped caps joined with circumferential post-tensioning.
  • the alternate rings would have nerve reinforcements on their outer face, and the union between all the rings, both ribbed and smooth, would be performed with longitudinal post-tensioning.

  • the edge of the reinforcements varies from the foundation to the head, as in the one recommended, but with the difference that the nerves are lightened, compared to the massifs of the English patent.
  • the width of the reinforcements is, approximately one quarter of the diameter of the cylinder, when this ratio in the recommended solution has not been exposed, due to the diversity of different actions that can be requested depending on the type of turbine that is mounted.
