Definitions

  • the invention relates to a wind turbine with a Aufwindkamin annularly enclosing, covered by a collector roof collector space, which is connected to the updraft chimney by a chute surrounding the winding chimney of flow channels, and arranged in the flow channels wind turbines having an axially flowed turbine rotor.
  • Wind turbines that use a Trowind Tan generally include a Tarwindkamin, which rises from a him enclosing, preferably covered with a translucent roof collector space, so that the collector space heated by solar radiation rises due to their lower density in the updraft chimney.
  • a Tarwindkamin wind turbine With the kinetic energy of the thereby resulting in Aufwindkamin flow is arranged in a Trowindkamin wind turbine is acted upon, which drives an electric generator. Since Tarwindkraftanlagen 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.
  • the invention is therefore based on the object, a wind turbine of the type described run so that both the fluidic and the static requirements can be met advantageously.
  • the invention solves this problem by the fact that the flow channels extend between radial to Aufwindkamin running, a support ring for Aufwindkamin receiving support walls that the rising in a flow direction portion of the flow channels below the support ring wind turbines are supported on the support walls of the upcomer and that the flow channels form a nozzle-like tapering towards the turbine rotor guide.
  • the sufficiently powerful formable supporting walls can namely record a flow channel bridging support ring for the updraft chimney, so that the loads through the updraft chimney and its loads from Support ring on the supporting walls and can be removed from the support walls in a suitable foundation.
  • the running between the support walls and below the support ring flow channels can therefore be designed without regard to the support of the updraft chimney with respect to a fluidically favorable updraft, especially since the wind turbines themselves are supported in the support walls.
  • the flow channels can therefore be readily formed with one each nozzle-like tapered towards the turbine rotor guide, so that set up particularly advantageous flow conditions in the inflow of each wind turbine.
  • the arrangement of the wind turbines in a section of the flow channels rising in the direction of flow assists in redirecting the radially upward flow in the inlet region of the flow channels into an axial chimney flow following the outlet region of the flow channels.
  • the baffle deflection can be provided with supporting baffles.
  • the flow conditions in the inlet region of the turbine rotor can be improved in that the flow channels in the inlet region of the nozzle-like guide in the longitudinal direction of the flow channels extending baffles.
  • the support ring for the updraft chimney comprises the support walls interconnecting the vaults enclosing the flow channels above. Due to the arching effect not only the loads of the vault are removed on the supporting walls, which cancel each other due to the closed ring of the vault effective side forces in the circumferential direction against each other, but also created advantageous geometric conditions for the implementation of the flow channels.
  • FIG. 1 shows a wind turbine according to the invention in a schematic longitudinal section
  • this wind turbine in a section along the line II-II of Fig. 1 and Fig. 3 is a section along the line III-III of Fig. 1 on a larger scale.
  • the wind power plant shown in FIGS. 1 to 3 comprises a wind chimney 1, which is enclosed by a collector space 2 enclosing it.
  • This covered with a translucent roof 3 collector chamber 2 is fluidly connected to the updraft chimney 1 through a ring of flow channels 4.
  • These flow channels 4 extend between radially with respect to the chute 1 aligned support walls 5, which receive a support ring 6 for the updraft chimney 1.
  • This support ring 6 is formed in an advantageous manner by the flow channels 4 above enclosing vault 7, which are supported on the support walls 5. The vault forces to be removed laterally cancel out substantially due to the ring of vault 7 closed in the circumferential direction.
  • the flow channels 4 thus essentially has the task of redirecting the updraft flow from the collector chamber 2 under a streamlined admission of the wind turbines 8 into the updraft chimney 1.
  • the turbine rotor 10 is provided in a flow-increasing portion of the flow channels 4.
  • the uprights and deflections supporting baffles 14 can be provided within the updraft chimney 1 in the outlet region of the flow channels 4, so that a laminar deflection of the updraft flow in the updraft chimney 1 is additionally supported.

Abstract

L'invention concerne une éolienne comprenant un compartiment collecteur (2) recouvert par un toit de collecteur (3) et entourant de manière annulaire une cheminée à vent ascendant (1), ledit compartiment collecteur (2) communiquant avec la cheminée à vent ascendant (1) par l'intermédiaire d'une couronne de canaux d'écoulement (4), entourant la cheminée à vent ascendant (1), ainsi que des turbines éoliennes (8) disposées dans les canaux d'écoulement (4), présentant un rotor de turbine (10) traversé axialement par le vent. L'objectif de l'invention est de créer des conditions de conception favorables. A cet effet, les canaux d'écoulement (4) s'étendent entre des parois de soutien (5) abritant une bague de support (6) pour la cheminée à vent ascendant (1) et s'étendant radialement par rapport à cette dernière; les turbines éoliennes (8) disposées dans une partie, ascendante dans le sens d'écoulement, des canaux d'écoulement (4), sous la bague de support (6), prennent appui sur les parois de soutien (5) de la cheminée à vent ascendant (1) et les canaux d'écoulement (4) forment une unité de guidage (12) se rétrécissant en forme de buse vers le rotor de turbine (10).
