    The invention relates to a wind turbine with a ring chimney enclosing a winding chimney of flow channels and arranged in the flow channels, a turbine rotor having wind turbines.
    Wind turbines, which use a Aufwindwirkung, generally include a Aufwindkamin, which rises from a surrounding him, preferably covered with a translucent roof collector space, so that in the collector chamber heated by solar radiation rises due to their lower density in the updraft chimney. With the kinetic energy of the thereby resulting in Aufwindkamin flow is arranged in a Aufwindkamin wind turbine is acted upon, which drives an electric generator. Since Aufwindkraftanlagen can only be used economically for higher performance, arise for the updraft chimney comparatively large dimensions, which in turn requires a correspondingly large-sized wind turbine. In order to use more economical wind turbines in this context, it has been proposed, instead of a large, concentrically mounted in the updraft duct wind turbine to provide a ring of smaller wind turbines in separate, radial flow channels that connect the collector space with the updraft channel. However, the arrangement of individual wind turbines with an axially impinged turbine rotor in a winding chimney enclosing wreath of flow channels brings with it design difficulties, because on the one hand a streamlined deflection of the updraft from the collector space in the updraft chimney is required and on the other hand for a stable, load-bearing support structure of the updraft chimney worry is. In addition, individual wind turbines should be accessible for maintenance without disturbing the operation of the other wind turbines. 2 ·· »« · · · · * * * * * * * * * * * * «« * * * * * * * * *
    The invention is therefore based on the object to perform a wind turbine of the type described so that not only the fluidic and static requirements can be met advantageously, but also a simple way for foreclosure of individual wind turbines for repair and maintenance is opened.
    The invention solves this problem by the fact that the flow channels extend between radially extending to the chimney, an annular support for the updraft chimney receiving walls, that the axis of the turbine rotors is transverse to the direction of flow and that the turbine rotors in the region of their counter to the direction of flow rotating peripheral side shielding by guide means, which comprise a pivot axis parallel to the axis of the turbine rotor between a flow position releasing the starting position and a flow position blocking this end position pivotally mounted guide walls.
    By providing radial support walls between the individual flow channels with respect to the updraft chimney, advantageous design prerequisites can be ensured both for the flow channels and for the removal of the loads caused by the updraft chimney. Namely, the support walls sufficiently powerful to form can accommodate an annular support for the updraft chimney bridging the flow channel, so that the loads can be removed by the updraft chimney and its loads from the annular support to the support walls and from the support walls into a suitable foundation. The running between the support walls below the annular support flow channels can therefore be allowed without regard to the support of the updraft chimney with respect to a fluidically favorable updraft, especially with the radial wind turbines used, the rotor axis is transverse to the direction of flow, the structurally available, substantially rectangular Flow cross-section of the flow channels can be considered advantageous. 3 3 • ΦΦΦ ΦΦ Φ Φ «Μ ΦΦ * ► Φ φ * ·» Φ Φ · · Φ > &phis; &phis; &phis; &phis; &phis; &phis; &phis; &phis; &phis; &phis; &phis; &phis; &phis;
    When using wind turbines with a turbine rotor whose axis extends transversely to the longitudinal direction of the flow channel, results for the turbine rotor a peripheral side which rotates in the direction of flow, and an opposite peripheral side with a direction of rotation against the direction of flow. In order to improve the flow conditions, therefore, the radial wind turbines are preceded by guide devices which deflect the flow in the area of the peripheral side of the turbine rotor moved counter to the flow to the opposite circumferential side rotating in the direction of flow. Include these baffles baffles which are mounted pivotably about a pivot axis parallel to the axis of the turbine rotor between an initial position releasing the flow path and an end position blocking this flow path, so the respective wind turbine without wind load for repair and maintenance purposes can be taken out of service on these Leiteinrichtungen. In addition, intermediate positions of these baffles permit an advantageous adaptation of the baffles to different flow conditions.
    Particularly advantageous construction conditions arise when the guide wall of the guide means is divided in an articulated manner parallel to its pivot axis. By virtue of the guide wall sections, which are pivotable relative to one another and articulated to one another, it is possible to set nozzle ratios which permit an improved laminar flow of the wind turbine due to a different inclination of the guide wall sections successive in the flow direction.
    So that loss-free deflection of the updraft flow from the radial flow channels into the updraft chimney can be achieved, corresponding guide walls can be arranged downstream of the wind turbines in a manner known per se. These extending between the support walls baffles can be mounted pivotably about horizontal axes to adjust them in case of need between a use position and the flow path through the associated flow channel blocking the closed position, which is an additional
    Shutoff of the individual flow channels on the downstream side of the wind turbines allowed.
    In the drawing, the subject invention is shown, for example. Show it
    Fig. 1 shows a wind turbine according to the invention in a schematic longitudinal section and
    Fig. 2 is a section along the line II-II of Fig. 1 on a larger scale.
    The wind turbine shown has a wind chimney 1, which is enclosed by a ring of flow channels 2. These flow channels 2 extend between with respect to the updraft chimney 1 radially aligned support walls 3, which receive an annular support 4 for the updraft chimney 1. Within the flow channels 2 wind turbines 5 are mounted, which are designed as radial turbines with turbine rotors 6, whose axis is transverse to the direction of flow, preferably vertically, so that the substantially rectangular flow cross-section of the flow channels 2 can be advantageously utilized for the turbine assembly. However, the embodiment of the turbine rotors 6 may be different. The drive connected to the respective turbine rotor 6 generator 7 is disposed in Fig. 1 below the wind turbine 5, but this is by no means mandatory.
    From the drawn in Fig. 2 flow arrow w shows that the turbine rotor 6 rotates on a peripheral side with the flow and on the opposite peripheral side against the flow To keep the associated counter torque as small as possible, is for a shield against the Flow rotating peripheral side worried. For this purpose, the turbine rotors 6 are preceded by guide devices 8 which have a guide wall 9 extending over the axial rotor length. These baffles 9 are supported at their side facing away from the wind turbine 5 sides to the rotor axis parallel pivot axes 10 on the support walls 3 and can between a flow path releasing starting position a and a flow path blocking this
    End position b are relocated. In the closed end position b of a guide 8, the associated wind turbine 5 is unhindered by otherwise occurring wind loads for repair and maintenance available, without affecting the operation of the other wind turbines 5.
    By an intermediate stiffening of the guide 8 shown in solid lines in FIG. 2, the turbine operation can be adapted to the respective wind conditions. In order to ensure particularly favorable flow conditions along the baffles 9, the baffles 9 can be articulated, so that the free baffle portion 11 can be pivoted relative to the hinged to the support wall 3 section of the baffle 9. With a pivoting adjustment of the free portion 11 of the guide wall 9 thus the channel flow can be deflected by the swung in the flow channel 2 free baffle section 16 under a shadow of the rotating against the flow peripheral side of the turbine rotor 6 in addition to the other side of the channel, so that in case of need with the flow rotating peripheral side of the turbine rotor 6 can be acted upon by a larger flow velocity.
    For low-loss deflection of the radial, horizontal Aufwindströmung in the inlet region of the flow channels 2, in an axial, vertical Aufwindströmung in the region of the Aufwindkamins 1 forms the bottom of the updraft chimney 1 a central distribution cone 12. In addition, in the outlet region of the flow channels 2, the deflector supporting baffles 13 are provided which extend between the support walls 3. These baffles 13 are preferably pivotally mounted about horizontal axes 14 between the support walls 11 to pivot these baffles 13 from the drawn in Fig. 1 in solid lines position of use in a flow path through the associated flow channel 2 locking closed position, as indicated by dash-dotted lines is. In the closed position of the wind turbines 5 downstream baffles 13 thus individual of the wind turbines 5 can be additionally sealed off from the updraft chimney 1.
