    Multi-platform wind tower. The object of the invention is to achieve a multi-platform tower, which makes it possible to significantly reduce manufacturing costs, since it is suitable for different types of turbines. For this, the improvements consist of obtaining a profile based on trunk-conical sections of different inclinations that corresponds geometrically with a load envelope obtained from the superposition of the theoretical profiles of respective towers designed specifically for a plurality of different turbines. Since each turbine has lower fixing means with a different diameter, it is necessary to have a series of adapters or reels (4-4 ') of frusto-conical configuration that allow the tower to be adapted to any type of turbine. If necessary, a second adapter (11), embodied in a wedge-shaped ring, could be arranged, which modifies the angle of the plane in which the blades rotate, separating the free end thereof from the tower.

    MULTI-PLATFORM WIND TOWER
    D E S C R I P C I O N
    OBJECT OF THE INVENTION
    The present invention relates to a wind tower, of those intended to support the corresponding wind turbine as a means of generating electric energy.
    The object of the invention is to provide a multi-platform or multi-turbine tower that allows to delve into cost savings in the manufacture of such structures, so that it does not have to be specifically designed for each type of existing turbine in the market, but, from a single tower model, for example of 120 meters of hub height, this is perfectly valid for a plurality of turbines of different manufacturers, so that this versatility of use allows obtaining the long extremely important economic savings.
    BACKGROUND OF THE INVENTION
    In the field of practical application of the invention, that of the concrete wind towers, to date, each wind tower was specifically designed for the specific turbine model that was to be installed in it, which means extremely high costs, which would clearly be desirable to minimize.
    Although in the invention patent P201430312, of which the applicant himself owns, a structure is described based on trunk-conical configuration segments, of different inclination, which allow obtaining a broken profile as close as possible to straight sections Theoretical and optimal curved profile planned for the tower, significantly reducing the cost in the manufacture of this type of structures, with said structuring the specific design of each tower for each specific turbine is still necessary.

    DESCRIPTION OF THE INVENTION
    The present invention focuses its characteristics on obtaining a tower based on segments that define sections for said trunk-conical configuration tower, but with the special feature that with specific characteristics for the design of the tower it is possible for it to obtain an extremely versatile character, being valid to withstand with total safety guarantees different types of turbines existing in the market with the interposition of one, or where appropriate, two simple adapter devices.
    To do this, and based on the need to have a tower of the order of 120 meters high hub, it is planned that the design of the tower consists of a load envelope according to the specifications of each of the manufacturers.
    The loads are classified first according to the type to which they belong, extreme, operational and fatigue, and then according to the maximum predominant effort in each case of loads: flexion, torsion and shear.
    The geometric fit obtained is based on parameters such as the maximum diameter allowed in blade tip and frequency range to prevent the tower from resonating and amplification of the acting loads.
    However, two alternative ways of obtaining the tower are planned:
    - Comply in all sections with the maximum diameter conditioner admitted in blade tip, (known parameter)
    - Comply in most sections with the maximum diameter conditioner admitted at the tip of the blade, so that in those where it cannot be met, a minimum angle of “conning” is applied
    In either case, the division of the tower into segments is defined by the

    transport criteria, it being convenient to limit the maximum weight of the dovela to 55 tons and a maximum width of it of 4.5 meters and a maximum length of 24 meters.
    Regarding the frequency range, based on the data corresponding to the different types of turbines, upper and lower limits thereof are calculated.
    In the same way, it is necessary to check the decompression in the joints, which is a condition of the prestressing on site, indirectly controlling the distance between anchors.
    At the same time it is necessary to check the minimum level of prestressing in the prestressed sections in the workshop, check the flexion and flush in the joints, conditioning the passive assembly in joints.
    From this structure, a multi-platform or multi-turbine tower is obtained, suitable to withstand the loads of very different types of turbines in the market, although, each turbine has screw fixing means arranged annularly, whose diameter It varies from one turbine to another, so it is necessary to adapt the diameter of the upper end or coronation of the tower to the diameter of the lower fixing means of the turbine, for which the inclusion of adapters or reels, materialized in metal bodies, preferably in the form of a cone trunk, which can be convergent or divergent in the upper direction so that in all cases a lower circular base of diameter according to that of the coronation of the tower is defined, with a perimeter flange with holes for the passage of the corresponding fixing screws, while the upper diameter of the reel will be different for each type of turbine , according to the specific needs of each case, this may be greater or less than the diameter of the coronation of the tower, and consequently determining the inverted shape or not of the trunk-conical configuration of the reel.
    Obviously, in the upper base of the reel a perimeter flange equipped with the corresponding holes for fixing by screwing the turbine will also be defined.

    As it is evident, the adapter's generator does not have to be strictly straight to obtain the same end, so that it could be curved or broken, without affecting the essence of the invention, since this would obey exclusively criteria of design.
    Although in the geometric study of the tower the theme of the “blade tip” (maximum diameter admitted at the blade tip) has been considered, there may be turbine models in which the blades have an insufficient separation so that by the configuration itself of the tower make the ends of said blade in its turn make a path too close to the tower at that point (being this section increasing in descending direction), for which the existence of a second type of adapter is planned , designed to slightly modify the position of the horizontal axis of the generator by moving to an insignificantly inclined position so that the sweeping plane by the blades automatically passes from a vertical position to a slightly inclined position, so that the tips of the blades are distanced Regarding the tower.
    This second adapter consists of a kind of circular crown, with a cradle-shaped profile, that is to say of variable thickness, and whose variation in thickness between one and the other end obviously depends on the modification in the degree of inclination of the blades that is desired get.
    As an example, a variation of 1 degree in the verticality of the plane of the blades would increase by more than one meter the separation of the end of said blades with respect to the tower in said extreme zone, for blades of 60 meters.
    Since the turbines can rotate to adapt to different wind directions, this cradle-like element is disposed between the means of articulation of the turbine and the general structure of the same, thus allowing to maintain the distance between the end of the shovels and the tower regardless of the orientation of the axis of rotation of the blades.
    In this way, it is possible to adapt very different types of turbines to a single tower that, although it is oversized and unitary, can be more expensive to manufacture, in the long run it entails significant economic savings, since it is not necessary to manufacture a tower

    PREFERRED EMBODIMENT OF THE INVENTION
    In figure 1, the theoretical profiles necessary for obtaining different types of 120-meter towers are shown in thinner sections, depending on the specifications of a series of turbines.
    As can be seen in thicker lines, by improving the invention, a profile is obtained for the tower that corresponds geometrically with the envelope of loads obtained from the superposition of the theoretical profiles mentioned above.
    In the present example, a tower obtained from six sections has been chosen, although, as previously mentioned, it can also be obtained from any number of sections.
    Well, from this tower, of invariable dimensions, a fixed upper diameter at its end or coronation (1) is defined for it, which obviously does not have to coincide with the different diameters of the fixing means lower (2) defined in correspondence with the lower face of each turbine (3).
    For this, the interposition between these elements of a reel (4-4 '), materialized in a metal body, with a cone-shaped configuration, divergent in the case of Figure 2, that is to say when the diameter is provided of the turbine fixing means (3) is greater than the diameter of the coronation (1) of the tower, or convergent, as in the case of figure 3, in which the diameter of the fixing means of the turbine (3 ') is smaller than the diameter of the coronation (1) of the tower.

    Consequently, the reel (4-4 ') has a circular bottom base with a diameter according to that of the coronation (1) of the tower, with an inner and bottom perimeter flange (5) provided with holes (6) for the passage of the corresponding fixing screws (7), while the upper diameter of the reel as shown in the figures, will be different for each type of turbine, according to the specific needs of each case, also including an upper inner perimeter flange (8 ) equipped with holes (9) for the passage of the corresponding fixing screws (10).
    As previously mentioned, and although the tower has been designed to take into account the separation of the blades of the different turbines with respect to the tower, in the case in some turbine model present a separation at the end level of its blades that is insufficient, the inclusion of a second adapter (11), the one shown in figures 4 and 5, is provided, and consists of a kind of circular crown, with a cradle-shaped profile, that is to say thickness variable, and whose variation in thickness between one end and the other obviously depends on the modification in the degree of inclination of the blades to be achieved, said crown being affected by a plurality of uniformly distributed holes (12).
    This adapter is arranged between the articulation means (13) of the turbine and the general structure of the same, with the corresponding bolts (14), thus allowing to maintain the distance between the end of the blades and the tower interchangeably of which is the orientation of the axis of rotation of the blades.
    For heights below 120 meters, the height of the lower section of the tower can be reduced, or even said section or more sections can be eliminated, depending on the height desired to be given to the tower.
    In parallel, for a higher height one or more sections can be added in the lower part of the tower.
