Abstract

The turbine includes a windbreaker comprising a plate (1) bent through an angle of 90 deg. and having a radius greater than that of the turbine. The plate is mounted on two rods (5) extending at right angles to each other which are fixed to a flange (4) on the outer edge of the casing for the blade rotor.

Description

       

  WINDMOLEN MET VERTICALE AS MET "WINDBREKER" MECHANISME

BESCHRIJVING VAN DE UITVINDING

  
Het gaat over een ontwerp die het rendement van de windgeneratoren met verticale as moet verhogen. Het belangrijkste onderdeel is een "windbreker" die de rol heeft om de wind altijd te laten vallen op de helft van de turbine.

  
De "windbreker" bestaat uit een over 90[deg.] gebogen plaat ( 1 ), met een radius groter dan de radius van de turbine (2). De plaat is gemonteerd op twee stangen (5), loodrecht op elkaar (fig. 1, boven), die vast geschroefd zijn op een flens (4) die gelagerd is op de buiten kant van het huis

  
(8) van de bladenrotor (7). Op deze manier kan dus de windbreker onafhankelijk draaien en de plaat (1) altijd op de juiste positie tegen de windrichting brengen (fig.2a, fig.2b), met behulp van de start (3), gemonteerd op een stang (6) die ook vast geschroefd is op de flens (4). De stang (6) staat op hetzelfde lijn met een van de stangen (5) die de plaat (1) recht houden.

  
Als de wind van richting veranderd (fig. 2b) komt op de start (3) een kracht die een draaiend moment creëert die de start (3) in een positie brengt waar de weerstand tegenover de wind nul is met, als resultaat, een nieuwe positie van de windbreker, met de plaat (1) die de helft van de turbine in de wind laat en de andere helft beschermt (fig. 2).

  WINDMILL WITH VERTICAL AXIS WITH "WINDBREAKER" MECHANISM

DESCRIPTION OF THE INVENTION

  
It is about a design that should increase the efficiency of wind generators with a vertical axis. The most important part is a "windbreaker" that has the role to always let the wind fall on half the turbine.

  
The "windbreaker" consists of a plate (1) bent over 90 [deg.], With a radius greater than the radius of the turbine (2). The plate is mounted on two rods (5), perpendicular to each other (Fig. 1, above), which are screwed onto a flange (4) mounted on the outside of the housing

  
(8) of the blade rotor (7). In this way the windbreaker can turn independently and always bring the plate (1) in the correct position against the wind direction (fig.2a, fig.2b), with the help of the start (3), mounted on a rod (6) which is also screwed to the flange (4). The rod (6) is aligned with one of the rods (5) that hold the plate (1) straight.

  
As the wind changes direction (Fig. 2b), a force is created on the start (3) that creates a rotating moment that brings the start (3) to a position where the resistance to the wind is zero, resulting in a new position of the windbreaker, with the plate (1) that leaves half of the turbine in the wind and protects the other half (fig. 2).

CONCLUSIES CONCLUSIONS Door het middel van het ontwerp werd de aangebonden windenergie maximaal gebruikt omdat alleen de helft van de turbine tegen de wind staat met als resultaat een groot draaimoment en dus hoger rendement. By means of the design, the wind energy used was maximally used because only half of the turbine is against the wind, resulting in a large torque and therefore higher efficiency. Aangezien de andere helft van de turbine weinig of geen weerstand ondervindt is het ontwerp zeer geschikt voor zowel extreem lage (2-3m/s) als grotere wind snelheden (4-30m/s). Since the other half of the turbine experiences little or no resistance, the design is very suitable for both extremely low (2-3 m / s) and larger wind speeds (4-30 m / s).
