Description
Um Windräder, besonders mittlere bis kleinere „Windmühlen“ etc. effizienter und stärker zu machen, werden von den vom Wind zu drehenden Mühlenstangen, Segelttuch- oder andere Windauffangflächen nach hinten und nach einer (immer der gleichen) Seite ausgebreitet und gespannt, so dahs sich eine gewölbte konkave, glatt gespannte Windführungsfläche ergibt, die nach hinten kleiner wird, weil die Spannseile oder Segelrahen nach hinten auf einen Ring wesentlich kleineren Durchmessers (im Vergleich zum vorderen Rotor) zulaufen und verankert/vertäut sind. Der Wind wirkt sich somit länger auf die Rotorradspeichen der Mühle /des Windrades/ drückend aus, indem er in Drehrichung verstärkt und ausgiebiger auf das Mühlengestänge mit den Segeln, dieses drehend, Arbeit ausübt. Es muss darum die von der Drehkuppel/dem Mühlenturmdach (drehbar gelagert) ausgehende, waagerecht vorgestreckte Achse des Rotors mitsamt Lagerung viel weiter nach vorne hervorragen, da Mühlenrad/Rotorrad der Segel also in gröhsserem Abstand vom Turm vom Wind gedreht werden.In order to make wind turbines, especially medium to small "windmills", etc. more efficient and stronger, the mill rods, canvas or other wind-collecting surfaces that are to be rotated by the wind are spread out and stretched towards one side (always the same), so there is no problem a convex, concave, smoothly tensioned wind guide surface results, which becomes smaller towards the rear, because the tensioning ropes or sail frames run towards the rear of a ring of significantly smaller diameter (compared to the front rotor) and are anchored / moored. The wind therefore has a longer impact on the rotor spokes of the mill / the wind wheel / by strengthening in the direction of rotation and more extensively on the mill linkage with the sails, turning it, doing work. It must therefore protrude the horizontally advanced axis of the rotor, including the bearing, extending from the rotating dome / the mill tower roof (rotatably mounted) much further to the front, since the mill wheel / rotor wheel of the sails are thus rotated a greater distance from the tower by the wind.
Der Wind kann dort dann länger auf die Rotorflügel einwirken, als wenn die Segeldreiecke nur zu den Spitzen der Mühlenstangen bzw. Rotorspeichen oder bis zu einer dort abzweigenden kurzen Rahe gezogen wären, wie ja schon gemacht wird. Dreieckssegel festgemacht an Spitze, vorderem Rad und hinterem Ring.The wind can then act longer on the rotor blades than if the sailing triangles were only drawn to the tips of the mill rods or rotor spokes or to a short branch branching off there, as is already done. Triangular sail attached to the tip, front wheel and rear ring.
Hierdurch werden die gewölbten Segelflächen gut gebläht und bieten dem Winde mehr Angriffsfläche zum Drehen des Rotors.As a result, the arched sail areas are well inflated and offer the winch more surface to turn the rotor.
Die erzielten Flächen können optional auch aus anderem Material, z.B Plastik, ausgeformt sein. Sie verlaufen jedenfalls eher spitz auslaufend zur Kuppel bzw. Turmdach hin bzw. zu einem kurz davor an der Rotorachse angebrachten Ring.The areas obtained can optionally also be formed from other material, e.g. plastic. In any case, they run rather pointedly towards the dome or tower roof or to a ring attached shortly before on the rotor axis.
Dabei müssen die Enden der Segeldreiecke an dem Ring ein Bogenstück weiter entgegen der Drehrichtung befestigt sein, so dahs die Segelflächen von den Mühlenstangen/den Speichen her schräg nach hinten - etwas spiralig - gelegt sind.The ends of the sailing triangles must be attached to the ring an arc further against the direction of rotation, so that the sail surfaces from the mill bars / spokes are slanted backwards - somewhat spirally.
Weil also der Rotor nunmehr gröhssere Raumtiefe hat, braucht er meistens auch eine Stütze für das Achslager weiter vor der Kuppel/vor dem Turmdach, in dem die Rotorachse kugelgelagert ist, bzw. durch die/den die Achse hindurchgeht, um am anderen Ende mit einem Gegengewicht gegen das vordere Gestänge- und Rotorgewicht ausgestattet werden zu können.Because the rotor now has a greater depth of space, it usually also needs a support for the axle bearing further in front of the dome / in front of the tower roof, in which the rotor axis is supported by ball bearings, or through which the axis passes, in order to be connected to one at the other end Counterweight against the front linkage and rotor weight can be equipped.
Die Segelflächen müssen gerefft werden können, dazu ist eine elektrisch betriebene Verdrehung des Spannseiles von Rotorstangenspitze, bzw. der Aufspannstange von dort zum Turmdach bzw. zum direkt vor dem Turmdach befindlichen, oben genannten Ring hin vorgesehen, diese Verdrehungs-Reffanlage liegt jeweils entweder im Turm oder ist an den betreffenden Kreisstellen des Ringes eingesetzt. So kann ein starker Sturm überstanden werden. Ausserdem sollte gegen eventuellen Orkan das Turmdach weggedreht werden, so dahs hinterseitig des Daches alle Rotorspeichenstangen - nach Ausklinken der Segelstangen oder Segelseile, die aber noch durch Tau verbunden bleiben mit dem Rotorzentrum, der Rotomabe, - fast kein Widerstand gegen den Orkan mehr vorhanden ist.The sail surfaces must be able to be reefed, for this purpose an electrically operated twisting of the tensioning rope from the rotor rod tip or the tensioning rod from there to the tower roof or to the above-mentioned ring directly in front of the tower roof is provided, this twisting reefing system is either located in the tower or is used at the relevant circular points of the ring. A strong storm can be weathered this way. In addition, against any hurricane, the tower roof should be turned away, so behind the roof all rotor spoke rods behind the roof - after the sail rods or sail ropes have been released, but which remain connected by rope to the rotor center, the rotomabe, - there is almost no resistance to the hurricane.
Die Rotorflügel/Rotorstangen sollten im Normalfall auch vorzugsweise alle an ihren Spitzen zueinander mit Sicherungsseilen verbunden sein, somit ein richtiges Rad ergebend.The rotor blades / rotor rods should normally also preferably all be connected to one another at their tips with safety ropes, thus resulting in a correct wheel.
Ich erbitte Patentschutz für diese Anlagen, die - wenn zahlreich errichtet - in vielen Gegenden, ohne zu grohse Windräder aufstellen zu müssen, weitgestreut überall aus der Windwalze, die oft genug über Land zieht, weitaus mehr an Energie abgreifen als bisher, was besonders auch für südliche Länder sehr grohssen Vorteil bringt.I am asking for patent protection for these systems, which - if built in large numbers - in many areas, without having to set up large wind turbines, take up far more energy than before, everywhere from the wind roller, which often moves overland, which is especially true for Southern countries brings great benefits.
