Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Erzeugung von elektrischer Energie aus einem Luftstrom.The invention relates to a device for generating electrical energy from an air stream.
Es ist bereits eine Vorrichtung zur Ausnutzung des Fahrtwindes und zur Umwandlung in elektrische Energie an Kraftfahrzeugen bekannt. Dabei sind die Fahrzeuge mit einen den Fahrtwind auf nehmenden Windkanal ausgestattet, der konisch ausgebildet ist und an dessen engstem Querschnitt ein Windrad angeordnet ist. Nachteil dieser Vorrichtung ist, daß die für die Fortbe wegung des Kraftfahrzeuges benötigte zusätzliche Energie größer ist, als die die über das Windrad erzeugt werden kann (DE-OS 32 01 555).It is already a device for exploiting the airstream and for conversion into electrical energy in motor vehicles known. The vehicles are up with the headwind taking wind tunnel equipped, which is conical and a wind turbine is arranged at its narrowest cross section is. The disadvantage of this device is that for the Fortbe movement of the motor vehicle required additional energy greater is than that which can be generated by the wind turbine (DE-OS 32 01 555).
Weiterhin wurde ein Wasserfahrzeug zur Umwandlung von Windenergie in elektrische Energie bekannt, wobei das Wasserfahrzeug mit vom Wind beaufschlagbare Vortriebsflächen aufweist und an seinem Schwimmkörper Wasserrotore befestigt sind, die bei Fahrbewegung aufgrund der entstehenden Wasserströmung rotieren und Generatoren zur Erzeugung elektrischer Energie antreiben (DE-OS 31 25 908).Furthermore, a watercraft was used to convert wind energy known in electrical energy, with the watercraft Has driving surfaces that can be acted upon by the wind and on its Floating water rotors are attached when moving due to the resulting water flow and generators rotate drive to generate electrical energy (DE-OS 31 25 908).
Ferner wurde ein Windenergie-Konverter in Form eines Vertikal achsenrotors mit zumindest einem oder mehreren aufrecht stehenden Flügeln bekannt, die unter der Windkraft längst einer etwa kreis förmigen Bahn um eine zentrale Vertikalachse umlaufen. Wesent liches Merkmal der Vorrichtung ist, daß die Masse der Flügel und der Radius seiner Umlaufbahn so gewählt sind, daß die auf die Flügel einwirkende Fliehkraft einerseits und die Luftkraft andererseits eine resultierende Windkraft erzeugen, die auch beim Luv- Durchgang der Flügel nach außen gerichtet sind (DE-OS 40 00 501). Furthermore, a wind energy converter in the form of a vertical Axis rotor with at least one or more upright Known wings that have long been approximately circular under wind power orbit around a central vertical axis. Essential Lich feature of the device is that the mass of the wing and the radius of its orbit are chosen so that the on the centrifugal force acting on the one hand and the air force on the other hand generate a resulting wind power that too the wings face outwards during the windward passage (DE-OS 40 00 501).
Diese Vorrichtungen haben gemeinsam den Nachteil, daß sie sehr aufwendig und teuer sind.These devices have the disadvantage that they are very common are complex and expensive.
Es ist die Aufgabe der Erfindung, eine Vorrichtung zur Erzeugung von Elektroenergie vorzuschlagen, die einfach und kostengünstig zu installieren und zu betreiben ist und die unabhängig von der natürlichen Luftzirkulation ist.It is the object of the invention to create a device of proposing electrical energy that is simple and inexpensive is to be installed and operated and which is independent of the natural air circulation.
Überraschenderweise wurde nun gefunden, daß dann eine einfache kostengünstige und weitgehend kontinuierliche Gewinnung von elektrischer Energie gelingt, wenn oberhalb der sich an den Fahrbahnrändern und den Mittelstreifen von Autobahnen und Straßen befindlichen Leitplanken eine Vielzahl vertikal stehender, zwei bis sechs Flügel aufweisende um die eigene Achse drehbare Vor richtungen angebracht werden. Die durch die vorbeifahrenden Fahrzeuge, insbesondere LKW und Busse erzeugte Drehbewegung der erfindungsgemäßen Vorrichtungen wird in bekannterweise in elektrische Energie mittels Generatoren umgewandelt und beispielsweise für Beleuchtungszwecke oder als Fußbodenheizung angewendet.Surprisingly, it has now been found that a simple one Inexpensive and largely continuous extraction of electrical energy succeeds when above the at the Road edges and median strips of highways and streets Guardrails located a variety of vertical, two to six wings with front rotatable around their own axis directions are attached. The by the passing Vehicles, in particular trucks and buses, produce rotary motion the devices according to the invention are known converted into electrical energy by means of generators and for example for lighting purposes or as underfloor heating applied.
