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 mounted within the flow duct wind turbine whose rotor axis is vertical, and with a turbine rotor in the region of its counter to the direction of flow rotating Circumferential side shielding guide.
  • the invention is therefore the object of a wind turbine of the type described in such a way that the different flow conditions of the flow channel can be considered advantageous.
  • the invention solves the problem posed by the fact that the channel wall forms on the counter to the direction of flow rotating peripheral side of the turbine rotor, the guide in the inflow of the flow channel and surrounds the turbine rotor on the upstream side in a peripheral region and that the duct forming the channel wall on the downstream side of the wind turbine Baffle carries, which is mounted on its front side facing away from the wind turbine end pivotally adjustable about an axis parallel to the rotor axis.
  • the guide wall has a minimum length corresponding to the width of the flow channel in its area, then the flow channel can be closed. In the blocking position of the baffle thus assembly and maintenance can be carried out safely by otherwise possibly occurring high flow velocities in the turbine area and in the flow channel.
  • the guide wall can be articulated parallel to its pivot axis, so that an improved diffuser effect in the area of the guide wall can be achieved by mutual pivotal adjustment of the guide wall sections to support a laminar flow possible laminar.
  • Fig. 1 shows a wind turbine according to the invention in a schematic, for
  • Fig. 2 is a section along the line II-II of Fig. 1 on a larger scale. Way to carry out the invention
  • the wind turbine shown has a flow channel 1 between two channel walls 2, which are formed by the mutually facing outer walls of two structures 3.
  • the height of this flow channel 1 is limited by a bottom 4 and the distance between the two structures 3 bridging ceiling 5.
  • the flow channel 1 defined by the two channel walls 2 has a course in the manner of a Venturi nozzle, as can be seen from FIG.
  • a wind turbine 6 is provided, the turbine rotor 7 extends over the height of the flow channel 1.
  • a generator 9 is driven.
  • the turbine rotor 7 is designed divided according to FIG. 2 in order to achieve an additional load transfer via the two structures 3 via a central carrier 10.
  • the upstream of the turbine rotor 7 for this purpose guide 11 is formed by the associated channel wall 2, which forms the guide 11 in the inflow of the flow channel and the turbine rotor 7 on the upstream side in a peripheral region 12 surrounds, so that the rotating against the channel flow peripheral side of the turbine rotor is covered against the channel flow.
  • the guide wall 11 forming channel wall 2 On the downstream side of the wind turbine 7, the guide wall 11 forming channel wall 2 carries a baffle 13 which is mounted pivotally adjustable at its side facing away from the wind turbine 6 end face about an axis parallel to the rotor shaft 8 axis 14.
  • the guide wall 13 which is partially swiveled into the flow channel 1
  • the flow conditions on the outflow side of the turbine rotor 7 can be influenced in the sense of a substantial maintenance of a laminar channel flow.
  • the baffle 13 has a minimum length corresponding to the width of the flow channel 1 in its area, the flow channel 1 can also be blocked so that assembly and maintenance work in the flow channel 1 can be carried out without endangering the wind.
  • the blocking position of the guide wall 13 is indicated by dash-dotted lines.
  • the guide wall 13 could be additionally divided in an articulated manner parallel to its pivot axis 14 on the turbine side opposite the guide 11 in order to allow an even better adaptation to a laminar flow.

Abstract

L'invention concerne une éolienne comportant un canal d'écoulement (1) entre deux parois de canal (2), dont au moins une forme une paroi extérieure d'un bâtiment (3), au moins une turbine éolienne (6) qui est montée à l'intérieur du canal d'écoulement (1) et dont l'axe de rotor s'étend verticalement, et une unité de guidage (11) protégeant le rotor de turbine (7) dans la zone de son côté périphérique tournant dans le sens inverse du sens d'écoulement du vent. L'objectif de l'invention est de permettre d'obtenir des conditions d'écoulement favorables. A cet effet, la paroi de canal (2) située sur le côté périphérique du rotor de turbine (7), tournant dans le sens inverse du sens d'écoulement, forme l'unité de guidage (11) dans la zone d'admission du canal d'écoulement (1) et entoure le rotor de turbine (7) sur le côté entrée dans une zone périphérique (12); en outre, la paroi de canal (2) formant l'unité de guidage (11) comporte une paroi de guidage (13) sur le côté sortie de la turbine éolienne (6) qui est montée de manière à pouvoir pivoter, sur son côté frontal opposé à la turbine éolienne (6), autour d'un axe (14) parallèle à l'axe de rotor.
