Abstract

The wind turbine has hydraulic pump that is mounted in or near the nacelle. The hydraulic pump is installed in base of plant or section or under the tower, so that heavy portions of head are displaced into base. The power is transmitted from top to bottom by hydraulic pumps and hydraulic passages. The wind turbine is located in base of tower. The generator, gearbox, pumps and electrical devices are located below ground level, in a state not contacting with landscape.

Description

Beschreibung der Anwendung des SystemsDescription of the application of the system

Bisher übliche Windkraftanlagen – kurz WKA – haben die gesamte Energieerzeugung, inkl. des Generators und ggf. Getriebes direkt im Kopfbereich, in der sog. „Gondel”, also direkt hinter den Rotorblättern. Das große Gewicht macht die Gondel und somit den gesamten Kopfteil der WKA, der sich in über 100, 200 m oder sogar mehr Höhe befindet, statisch sehr anfällig. So müssen bisherige WKA sehr stabil gebaut werden.Previously common wind turbines - short WKA - have the entire power generation, including the generator and possibly transmission directly in the head area, in the so-called. "Gondola", ie directly behind the rotor blades. The large weight makes the gondola and thus the entire headboard of the wind turbine, which is located in over 100, 200 m or even more altitude, very susceptible to static. So previous WKA must be built very stable.

Unsere Erfindung und Patentanmeldung soll durch die Verlagerung eines großen bzw. Haupt-Gewichtsanteiles in den Fußbereich eine wesentliche Optimierung hervorbringen, die folgende Vorteile aufweist:

  • – Großer Vorteil: hohe Materialersparnis, durch filigranere, dünnere und leichtere Türme
  • – Wesentlich montage- und wartungsfreundlicher, da Wartung und Austausch auf Bodenebene erfolgt
  • – Keine große Gondel erforderlich
  • – Statisch sehr viel stabiler, da kein großes Gewicht im Kopfbereich mehr
  • – dadurch sehr Sturmsicher
  • – geringeres Blitzrisiko, da sich im Kopfbereich nur Hydraulikelemente befinden, die gesamte Elektrik befindet sich im Fuß, galvanische Trennung einfach möglich
Our invention and patent application is intended to bring about a substantial optimization by the displacement of a large proportion of weight in the foot area, which has the following advantages:
  • - Big advantage: high material savings, through more filigree, thinner and lighter towers
  • - Much easier to assemble and maintain as maintenance and replacement takes place at ground level
  • - No big gondola required
  • - Static much more stable, because no more weight in the head area more
  • - Very storm proof
  • - Lower lightning risk, as there are only hydraulic elements in the head area, the entire electrical system is located in the foot, galvanic isolation is easily possible

Diese Vorteile führen zu folgenden Effekten:

  • – Herstellung von kostengünstigeren WKA möglich
  • – Finanzierung der kostengünstigen WKA wesentlich einfacher möglich, was die Verbreitung ankurbeln wird.
  • – Strompreise werden sinken
  • – Der Einsatz erneuerbaren Energien wird auf diese Weise sehr stark unterstützt (!)
These advantages lead to the following effects:
  • - Production of less expensive wind turbines possible
  • - It will be much easier to finance low-cost WTGs, which will stimulate dissemination.
  • - Electricity prices will fall
  • - The use of renewable energies is strongly supported in this way (!)

Funktionsprinzipprinciple of operation

Siehe hierzu beiliegende Zeichnung. In der Gondel im Kopfbereich werden die Rotoren wie bisher eingesetzt. Die Gondel fällt äußerst klein aus, weil sich darin lediglich eine Hydraulikpumpe befindet. Über die Hydraulikleitungen wird die Energie in den Fußbereich befördert. Dort befindet sich der Generator, ggf. mit vorgeschaltetem Getriebe, und produziert den elektrischen Strom.See enclosed drawing. In the nacelle in the head area, the rotors are used as before. The gondola is extremely small, because there is only a hydraulic pump in it. The energy is transferred to the foot area via the hydraulic lines. There is the generator, possibly with upstream transmission, and produces the electric current.

Entwicklungdevelopment

Die Entwicklungsarbeiten sind im Verbund mit Firmen geplant, die im Bereich Mechanik und Hydraulik ihren Schwerpunkt haben. Den elektrischen und elektronischen Teil wird Fa. SolteQ übernehmen.The development work is planned in conjunction with companies that focus on mechanics and hydraulics. The electrical and electronic part will be taken over by SolteQ.

Technische Realisierungtechnical realization

Das fertige Produkt ist als Zulieferprodukt für Windkrafthersteller angedacht. Eine Fertigung in Lizenz ist auch denkbar.The finished product is intended as a supplier product for wind power manufacturers. A production under license is also conceivable.

Marktchancenmarket opportunities

In dieser Erfindung sehen wir enorm große Marktchancen, da es solch ein WKA-System auf dem gesamten Weltmarkt noch nicht gibt. Mit all den genannten Vorteilen gegenüber bisherigen Windkraftanlagen, insbesondere der enormen Kostenersparnis ist der Markt für dieses System sehr offen. Gerade bei den aktuellen weltweiten Aktivitäten ist dies ein enormer Beitrag für erneuerbare Energien und wird den Markt revolutionieren.In this invention, we see tremendous market opportunities, as there is no such WKA system on the entire world market. With all the above advantages over previous wind turbines, in particular the enormous cost savings, the market for this system is very open. This is an enormous contribution to renewable energies, especially in the current global activities, and will revolutionize the market.

Produktionproduction

Die Produktion soll bei der Firma SolteQ GmbH mit Sitz in Oberlangen erfolgen. Eine Produktion in Lizenz durch Windkraftanlagenhersteller ist ebenfalls durchaus denkbar.Production is to take place at SolteQ GmbH, based in Oberlangen. Production under license by wind turbine manufacturers is also conceivable.
