Abstract

The generator consists of a rotor (8) with internal opposite baffle surfaces (4). These are position-controlled by toothed gears, and extract energy from the flowing water. The baffles are fastened to shafts, and are constantly turned by a set gear arrangement into the most ideal position for highest efficiency. Each shaft has one baffle, and a pair of toothed gears (2,3), which roll off a central fixed gear (1). The central gear forms a stator, and is fastened with its central axis (9) to the anchoring (5). The tooth ratio, between the central gear and the one other gear (3), is fixed at 1:2, while the intermediate gears (2) may be of varying size.

AllgemeinesGeneral

Der von mir hier vorgestellte Umweltgenerator wird durch die natürliche Energie des fließenden Wassers angetrieben. Dabei übt die Strömung auf zwei oder mehr Prallflächen eine Kraft aus, die den Generator (Rotor) antreibt. In der Abb. 1 und Abb. 1a ist das Prinzip eines rechtsdrehenden Funktionsmodells dargestellt. Die Pfeile symbolisieren die auf die Prallflächen wirkende Kraft bei vorgegebener Strömung von unten. Wie aus der Abb. 2/Abb. 2a zu entnehmen ist, wird die Steuerung (Stellung) der Energie erzeugenden Prallflächen während der Rotation von einer bestimmten Anordnung von Zahnrädern übernommen. Die äußeren Zahnräder sind mit den Achsen und den daran angebrachten Prallflächen fest verbunden, die Stellung der Prallflächen wird dadurch immer in einem idealen Winkel zur Strömung gehalten. Dabei ist das Zahnverhältnis des zentralen Rades (1) zu den außen liegenden Steuerrädern (3) vorgegeben, die zwei Verbundräder (2) sind variabel und dienen
The environmental generator I am presenting here is powered by the natural energy of the flowing water. The flow exerts a force on two or more impact surfaces that drives the generator (rotor). Fig. 1 and Fig. 1a show the principle of a right-handed function model. The arrows symbolize the force acting on the baffles for a given flow from below. As can be seen from Fig. 2 / Fig. 2a, the control (position) of the energy-generating baffles during the rotation is taken over by a certain arrangement of gear wheels. The outer gears are firmly connected to the axles and the baffles attached to them, the position of the baffles is always kept at an ideal angle to the flow. The tooth ratio of the central wheel ( 1 ) to the external steering wheels ( 3 ) is specified, the two compound wheels ( 2 ) are variable and serve

  • a) zur Drehumkehr der Steuerräder unda) for turning the steering wheels and
  • b) zur Größenanpassung des Generators in Bezug auf seinen Durchmesser.b) to adjust the size of the generator in relation to its diameter.

Das zentrale Zahnrad mit seiner Achse (Stator) ist fest mit der Verankerung verbunden und bleibt somit während des Betriebes in seiner Position stehen. Der sich drehende Teil (Rotor) ist auf der Mittelachse gelagert und damit rotationsfähig. Während der Drehung des Rotors rollen sich die Zahnradpaare (2/3) auf dem zentralen Zahnrad (1) ab und drehen damit die Prallflächen In einen Idealen Winkel. Oberhalb des Rotors liegt eine ebenfalls auf der Mittelachse gelagerte und über die außen liegenden Achsen mitgenommene Scheibe, die der Abnahme der erzeugten Leistung dient. Die äußeren Achsen sind in der Ausgangsposition so justiert, daß eine Prallfläche dem fließenden Wasser die gesamte Fläche entgegenstellt, während die andere Seite dem fließenden Wasser keinen Widerstand bietet. The central gearwheel with its axis (stator) is firmly connected to the anchorage and therefore remains in its position during operation. The rotating part (rotor) is mounted on the central axis and is therefore capable of rotation. As the rotor rotates, the gear pairs ( 2/3 ) roll on the central gear ( 1 ) and thus rotate the baffles at an ideal angle. Above the rotor is a disc, which is also mounted on the central axis and is carried along by the external axes and serves to reduce the power generated. In the starting position, the outer axes are adjusted so that one baffle surface opposes the entire surface to the flowing water, while the other side offers no resistance to the flowing water.

Während einer vollen Umdrehung des Generators (siehe Abb. 1) werden die Prallflächen um 180° gedreht, d. h., wenn sie ihre Ausgangsposition wieder erreichen, ist der Grundzustand mit wechselnder Seite der Oberfläche wieder wie zu Beginn der Drehung vorhanden. Auch während der Rotation sind die Flächen immer in einer Idealen Ausrichtung (Abb. 1) und erzeugen somit fast während der gesamten Drehung nutzbare Leistung.During a full revolution of the generator (see Fig. 1), the baffles are rotated by 180 °, ie when they reach their starting position, the basic state with the alternating side of the surface is again as it was at the beginning of the rotation. Even during rotation, the surfaces are always in an ideal orientation ( Fig. 1) and thus generate usable power almost throughout the rotation.

Diese Leistung wird über die Außenachsen in Form von Mitnehmern an eine zentral gelagerte Abnehmerscheibe abgegeben. Mittels Abnehmer wird nun die Energie auf einen Strom­ generator zur Erzeugung elektrischer Energie übertragen.This power is transferred to a central one via the outer axles in the form of drivers Dispenser disc delivered. The energy is now transferred to a current by means of a customer generator for generating electrical energy.

Leistungpower

Für die Leistung sind 3 Parameter zu betrachten:
There are 3 parameters to consider for performance:

  • 1. Fließgeschwindigkeit des Gewässers1. Water flow rate
  • 2. Größe der Prallflächen2. Size of the baffle
  • 3. gesamter Wirkungsgrad ein-/mehrflügelig (η).3. Overall efficiency with one or more blades (η).

Sowohl die Höhe als auch der Durchmesser des Generators und damit der Größe der Prallflächen sind variabel und können damit den spezifischen Gegebenheiten problemlos angepaßt werden.Both the height and the diameter of the generator and thus the size of the Baffle surfaces are variable and can therefore easily meet the specific circumstances be adjusted.

Die komplette Konstruktion wird unterhalb des Wasserspiegels betrieben, die Energie erzeugenden Prallflächen sind dadurch fast während der gesamten Rotation wirksam. Die erzeugte Leistung steht im Regelfall während 24 h pro Tag zur Verfügung! Kurzfristige Leistungsschwankungen treten nicht auf.The entire construction is operated below the water level, the energy Generating baffles are effective almost throughout the rotation. The generated power is usually available 24 hours a day! Short term There are no fluctuations in performance.

Die unterschiedliche Stellung der Flächen während der Rotation ergibt rechnerisch immer die gleiche Gesamtleistung. In Wirklichkeit zeigt sich im Versuch (2 flügeliges Modell) bei der Mittelstellung, d. h. beide Flächen unter 45° hintereinander angeordnet, daß durch Verwirbelung der vorderen Fläche kurzzeitig ein kleiner Leistungsabfall zu verzeichnen ist. Dieser kurze Leistungsabfall wird durch die Masse des sich drehenden Rotors ausgeglichen und ist in der Rotation nicht feststellbar. The different positions of the surfaces during the rotation always result in the calculation same overall performance. In reality, the experiment (2-wing model) shows in the Middle position, d. H. both surfaces arranged at 45 ° in a row that by Whirling of the front surface briefly a small drop in performance is noted. This short drop in performance is compensated for by the mass of the rotating rotor cannot be determined in rotation.  

Einsatzcommitment

Der Umweltgenerator kann in jedem fließenden Gewässer, ohne Veränderung der natürlichen Gegebenheiten, ab einer gewissen Fließgeschwindigkelt und Wassermenge pro Zeiteinheit eingesetzt werden. Dabei erscheint es sinnvoll, Gruppen mit versetzter Anordnung zu bilden (siehe Abb. 3). Der Umweltgenerator wird auf Grund seiner Bauart komplett unterhalb der Wasseroberfläche betrieben, bei entsprechender Kapselung kann auch der Stromgenerator getaucht angetrieben werden. Durch Einsatz von Schwimmkörpern soll der Umweitgenerator In einer konstanten Tiefe zur Wasseroberfläche gehalten werden. Ein vorgelagertes grobes Netz verhindert das Eindringen von größerem Schwemmaterial, die geringe Drehzahl des Rotors übt auf die im Wasser lebende Tierwelt keinen negativen Einfluß aus. Durch geschickte Anordnung von Leitblechen kann der Wirkungsgrad der Anlage weiter gesteigert werden.The environmental generator can be used in any flowing water, without changing the natural conditions, from a certain flow speed and amount of water per unit of time. It makes sense to form groups with a staggered arrangement (see Fig. 3). Due to its design, the environmental generator is operated completely below the surface of the water; if encapsulated accordingly, the power generator can also be driven submerged. By using floating bodies, the secondary generator should be kept at a constant depth to the water surface. An upstream coarse network prevents the penetration of larger debris, the low speed of the rotor has no negative impact on the aquatic wildlife. The efficiency of the system can be further increased by cleverly arranging baffles.

Die Konstruktion läuft absolut geräuschlos und trägt den Erfordernissen des Umwelt- und Naturschutzes in vollem Umfang Rechnung.The construction runs absolutely noiseless and meets the requirements of the environmental and Conservation in full account.
