    The invention relates to a tower-like, hollow structure, in particular a Aufwindkamin, with a jacket and with at least one vibration damper, which has a pendulum mounted within the shell, supported on the jacket via radial damping elements balancing mass.
    In order to achieve an effective vibration damping for the tower of a wind turbine with a wind turbine, for example, placed on the tower, it is known (EP 1 008 747 A2) to provide in the hollow tower a pendulum suspended balancing mass and so supported against the tower via damping and spring elements in that the balancing mass oscillates correspondingly out of phase with respect to the tower and thus a substantial vibration damping for the tower can be achieved. However, such balancing weights suspended in the area of the tower axis are only of limited suitability for updraft chimneys in whose shell an updraft flow should form as undisturbed as possible. This is especially true for updraft chimneys with a comparatively thin shell, which is stiffened at least in a cross-sectional plane by means of a spider. For this purpose it is known (DE 103 59 765 A1) to use a reinforced ring portion of the chimney jacket as a pressure ring for the spider, so that only the spokes must be pre-mounted on the hub of the spider before the spokes by means of mounting parts in the intended Cross-sectional plane can be raised with entrainment of the hub and supported under a bias on the reinforced ring portion of the chimney jacket. This spokes are namely the arrangement centrally suspended and opposite to the jacket via spring and damping elements radially supported compensating masses. 1 • * • 1 • * • • • • • • · · * * * • • • • • * *

    The invention is therefore an object of the invention to provide a tower-like, hollow structure, especially a Aufwindkamin, which allows an advantageous vibration damping without jeopardizing the necessary stiffening of the structure or sustainably affect a warm-up flow.
    Starting from a tower-like, hollow structure of the type described above, the invention solves the problem by the fact that the balancing mass is in the form of a concentric to the shell of the structure ring body and that the radial damping elements are supported on a reinforced ring portion of the shell.
    Due to the design of the balancing mass in the form of a jacket of the building concentric ring body can be kept free in the case of Aufwindkamins the flow path for the updraft within the updraft chimney, so can not only einhatten advantageous flow conditions, but also a little costly support of the ring body against the jacket the structure is possible because the radial distance between the shell of the structure and the annular body of the balance mass can be comparatively small. However, it is to provide for a corresponding initiation of the force exerted by the balancing mass on the jacket of the building forces, which requires a reinforced ring portion of the shell. Since the balancing weights are advantageously provided in the region of the largest vibration amplitudes of the shell of the structure, and therefore the jacket is generally stiffened in this area, resulting from the requirement of a reinforced ring section for supporting the balancing mass against the jacket no additional design effort. Braces for hollow, tower-like structures can be advantageously provided in the form of spokes, the spokes on a central hub tensile load and are supported on a reinforced ring portion of the shell under bias. A Ausgogmasse in the form of an annular body does not hinder this stiffening by a spider, because the annular body of the balancing mass arranged directly above or below the spokes, but can also be provided with radial grooves for receiving the spokes.
    Since the balancing mass in the form of a substantially matched to the inner diameter of the shell of the building ring body brings large diameter for the ring body, the ring body can be composed of individual segments for design and assembly simplification, the segments of the ring body are preferably hinged together to avoid constraining forces within the ring body.
    The pendulum bearing of the annular balancing mass can be done by a suspension of the ring body on the shell of the structure via appropriate traction means, in particular ropes, whose articulation usually requires a reinforced ring section of the shell again on the mantle of the building.
    Does the building on a stiffener in the form of a spider ring, which are supported on a hub, radial spokes on the reinforced ring portion of the shell are supported under a bias, so it opens up the possibility of hanging the ring body of the balancing mass to the spokes of the spokes pendulum. For this purpose, the ring body can be articulated on all sides limited pivotally mounted handlebars on the spokes of the spokes. This on all sides limited pivotal mounting of the handlebar both in the area of the spokes and in the region of the annular body can be ensured that the link between the spokes of the spider and the ring body on the one hand in the direction of the associated spoke axis and about an axis perpendicular thereto the spokes and on the other hand are hinged to a circumferentially of the annular body and about an axis extending in the radial direction pivotally mounted on the annular body. By this pivotability of the handlebars to each two mutually perpendicular axes which is required for vibration damping of the structure respectively required compensating vibration of the annular body of the balancing mass as a function of the vibration excitation of the structure.
    In the drawing, the subject invention is shown, for example. Show it
    1 shows a vibration damper of a chimney invention partially in the region of the reinforced ring portion of the chimney jacket in a schematic axial section,
    2 shows a section along the line II-II of FIG. 1 on a smaller scale,
    3 is a view of the inside of the annular body of the balancing mass in the direction III of Fig. 2,
    4 a representation corresponding to FIG. 1 of a construction variant of an updraft according to the invention, FIG.
    5 shows a section along the line V-V of Fig. 4 and Fig. 6 shows a section along the line Vl-Vl of Fig. 4th
    As the embodiment according to FIGS. 1 to 3 can be seen, the updraft chimney, of which only the shell 1 is shown in a section, provided with a vibration damper 2, which has a pendulum mounted balancing mass in the form of a concentric to the shell 1 ring body third having. This annular body 3 is composed of individual segments 4, which are connected by means of axially parallel axes 5 hinged together. At these axes 5 preferably apply traction means 6, for example ropes, on, over which the annular body 3 of the balancing mass distributed over the circumference is suspended on the jacket 1 of the updraft chimney. Of Fig. 1 can be seen in this context that the traction means 6 via push rods 7, which are tensioned by tension cables 8 against the jacket 1, are guided at a predetermined radial distance from the shell 1, the length of the traction means 6 and the Mass of the annular body 3 dependent resonant frequency of the balancing mass can be adjusted to adapt to the natural frequency of the updraft chimney in the region of the vibration damper 2 via spring elements 9, with the help of the annular body 3 is supported radially on the jacket 1. To stiffen the sheath 1 in this area a reinforced ring portion 10, which can serve as an external Drudering for a spoked wreath, the spokes 11 at a central hub zugfest attack and tie rods 12, which enforce the reinforced ring portion 10 and on the outside of the ring are supported on a clamping device 13, are held under pretension.
    In addition to the radial support of the annular body 3 by spring elements 9 damping elements 14, for example in the form of damping cylinders, are provided between the annular body 3 and the reinforced ring portion 10 of the shell 1. The annular body 3 of the balancing mass can thus perform in the direction of the respective vibrations of the shell 1, but to these out of phase, damped compensating vibrations, which lead to a substantial vote on the respective design conditions to a substantial eradication of the cladding vibrations.
    The embodiment according to FIGS. 4 to 6 differs from that according to FIGS. 1 to 3 essentially by the suspension of the annular balancing mass. The annular body 3 of this Ausgichmasse is in fact mounted pendulum on the spokes 11 of the spider, via link 15, which are pivotally mounted about an associated tie rod 12 axis 16 on a bearing body 17, which itself to a corresponding tie rod 12 coaxial axis 18 can be turned. In an analogous manner, the handlebar 15 is rotatably mounted on a bearing body 20 via a pivot axis 19 extending in the circumferential direction of the annular body 3, which is mounted on the ring body 3 so as to be pivotable about a vertical axis 21. The axis 21 is preferably held in a bearing fork 22, on which the axis 5 acts between the segments 4 of the annular body, as can be seen in particular FIGS. 4 and 5.
    Due to the thus made possible on all sides limited pivoting linkage of the handlebars 15 on the one hand to the tie rods 12 of the spokes 11 and on the other hand to the segments 4 of the ring body 3 is again a direction independent pendulum mounting of the balancing mass ensured to ensure effective vibration damping if necessary. The equalizing vibrations of the
    Compensating mass can be attenuated according to the embodiment of FIGS. 1 to 4 via damping elements 14.
    To adapt the damping of the compensating vibrations between the casing 1 and the annular body 3 of the balancing mass to the respective vibration conditions, the damping behavior of the damping elements 14 can be regulated in dependence on predetermined control programs. For this purpose, according to FIG. 5, the vibration behavior of the shell 1 and of the annular body 3 can be detected via acceleration sensor 23 and transmitted to a control device 24, which controls the actuating drives of corresponding throttle valves 25 for the damping elements 14 designed as damping cylinders as a function of the respective specifications , Since under certain circumstances due to expected temperature fluctuations with significant changes in the viscosity of the hydraulic fluid of the damping cylinder must be expected to take into account such temperature-dependent viscosity fluctuations, the temperature of the Hy-draulikmittels example, via a temperature sensor 26 in a reservoir 27 for the hydraulic medium measured and the control device 24th be forwarded to control the throttle valves 25 in dependence also on the respective viscosity of the hydraulic medium.
    The invention is of course not limited to the illustrated embodiment of a water chimney, but can be used in all tower-like structures that form a central cavity. The mantle of this structure must by no means be formed by an outer wall. It is crucial that at least one central shaft is present, which can accommodate a balancing mass in the form of a ring body.
