Definitions

  • the invention relates to a wind turbine with a flow channel between two channel walls, at least one of which forms an outer wall of a building, with at least one inside the flow channel mounted, axially flowed through the wind turbine and upstream of the turbine rotor in the direction of flow, in the direction of flow nozzle-like tapered guide ,
  • the invention is therefore based on the object, a wind turbine of the type described in such a way that with comparatively simple structural measures advantageous loading of the wind turbine despite different wind conditions can be achieved.
  • the invention solves the stated object in that the nozzle-like guide has a channel wall associated, extending substantially to half the circumference of the guide portion extending on the side facing away from the turbine rotor about a vertical axis pivotally adjustable is stored.
  • a guide section of the guide device can be pivoted away from the channel wall into the channel flow about an axis which extends at an axial distance from the wind turbine in the region of the associated channel wall with the effect that the flow cross section in the immediate inflow region of the wind turbine decreases. which entails an acceleration of the wind turbine impinging flow and can be used to advantageously control the speed of the turbine rotor. Since this guide section encompasses essentially half the guide device, which is pivoted against the other half of the guide device, sufficiently laminar flow conditions can still be ensured for an advantageous flow loading of the wind turbine, which, however, is supplied with increasingly eccentric flow. The desired by the guide nozzle effect remains yes even with a pivoting adjustment of the pivotable guide section obtained.
  • the guide sections can be divided in an articulated manner parallel to their pivot axis. that can be set by a mutual pivotal adjustment of resulting by the articulated part of the guide sections more favorable flow conditions for the individual wind turbines.
  • the pivotable guide section can also be utilized for blocking the flow passage through the respective nozzle. It only needs to be provided for this purpose, only the pivotable guide portion transverse to the flow channel. If necessary, a stop for the pivotable guide section on the opposite channel wall can be provided for a corresponding seal.
  • Flow channels between each two structures are aligned with respect to a given main wind direction, which often rotates 180 degrees in a day-night rhythm. It is recommended in such a case to use oppositely inflatable wind turbines and assign them on both sides of a guide with a pivotable guide section in order to use the possible control interventions in both directions.
  • FIG. 1 shows a wind turbine according to the invention in a partially torn, schematic plan view
  • FIG. 3 shows the wind turbine of FIGS. 1 and 2 in a view in the direction of flow
  • Fig. 4 shows an embodiment variant of a wind turbine according to the invention in a partially torn plan view
  • FIG. 5 is a corresponding to FIG. 1 representation of an embodiment of a wind turbine according to the invention.
  • the wind power plant according to the embodiment according to FIGS. 1 to 3 comprises a flow channel 1 between two structures 2, whose mutually facing outer walls give the flow channel 1 in the manner of a Laval nozzle limiting channel walls 3.
  • wind turbines 4 are arranged in the longitudinal center of this flow channel 1 distributed over the channel height.
  • the axial throughflow turbine rotors 5, which are mounted in between the channel walls 3 extending supports 6 and provided with radially projecting rotor blades 7, nozzle-like baffles 8 are associated on both sides, which are within the flow channel 1 between a bottom 9 and a ceiling 10th forming flow in laminar as possible partial streams to act on the individual wind turbines 4 share.
  • the flow of wind turbines 4 can be controlled in response to the changing wind conditions, um- 1 to 3, the nozzle-like guide devices 8 a guide portion 11 associated with a channel wall 3 extending essentially around half the circumference of the guide 8, pivotally adjustable on the channel wall 3 about a vertical axis 12 on the front side facing away from the turbine rotor 5 is stored.
  • This guide section 11 can be pivoted into the flow channel 1 from a starting position adjacent to the associated channel wall 3, in which the nozzle-like guide device 8 releases the full inflow cross section for the turbine rotor 5.
  • partitions 14 Due to the arrangement of the individual wind turbines 4 respectively associated guide devices 8 results in the possibility of subdividing the flow channel 1 between the individual wind turbines 4 associated baffles 8 in height by partitions 14.
  • partitions 14 between the guide devices for the lowermost and the middle of the three superposed wind turbines 4 shown.
  • partitions 14 could also be provided between the guide devices 8 for the two upper wind turbines 4.
  • the partitions 14 on both sides of the wind turbine 4 divide the flow channel 1 in height, this is not mandatory.
  • the partition 14 to seal off the lowermost wind turbine 4, it is sufficient to block the portion of the channel flow flowing through this wind turbine 4, for which a partitioning on either the inflow or outflow side is sufficient. It therefore requires the partition 14 to be arranged only on a wind turbine side to z. B. to make during the operation of the upper wind turbines 4 maintenance on the lower wind turbine 4.
  • FIG. 4 additionally shows that the pivotally adjustable guide sections 11 of the guide devices 8 can also be used to lock the flow channel 1, namely, when the length of the guide section 11 of the nozzle-like guide devices 8 measured in the longitudinal direction of the flow channel 1 approaches the width of the flow channel 1 in the region of these guide devices 8 is adjusted.
  • the at least partially blocking the flow channel 1 by a deflected transversely to the flow channel 1 guide portion 11 of the guide 8 at least on one side of the channel assembly and maintenance in the closed area of the flow channel 1 without wind hazard can be performed.
  • the embodiment according to FIG. 5 differs from that illustrated in FIGS. 1 to 3 essentially in that the guide devices 8 form guide sections 11 opposite one another with respect to the flow channel 1, which each face away from the turbine rotor 5 about a vertical axis 12 Front side pivotally mounted on the channel wall 3 are mounted.
  • these guide sections 11 are articulated parallel to their pivot axes 12.
  • the joints are designated 15.
  • the guide sections 11 form two mutually pivotally adjustable parts, which allow better flow guidance, in particular for larger deployment angles, in order to be able to act on the respective wind turbines 4 with as laminar a flow as possible.

Abstract

L'invention concerne une éolienne comportant un canal d'écoulement (1) entre deux parois de canal (3), dont au moins une forme une paroi extérieure d'un bâtiment (2), au moins une turbine éolienne (4) qui est montée à l'intérieur du canal d'écoulement (1) et traversée axialement par le vent, et une unité de guidage (8) montée, dans le sens d'écoulement (13) du vent, en amont du rotor de turbine (5) et se rétrécissant en forme de buse dans le sens d'écoulement (13). L'objectif de l'invention est de faciliter la commande de l'arrivée du vent sur la turbine éolienne (4). A cet effet, selon l'invention, l'unité de guidage (8) en forme de buse présente au moins une partie de guidage (11) associée à une paroi de canal (3), s'étendant sensiblement sur la moitié de la périphérie de l'unité de guidage (8) et montée de manière à pouvoir pivoter autour d'un axe vertical (12) sur le côté frontal opposé au rotor de turbine (5).
