Abstract

The small floating power plant is anchored in streams and rivers and has a relatively wide inlet opening for the active top layer of the water stream. During the flow the stream velocity is braked, resulting in the release of an energy which can be converted into electric current. Inside the inlet opening a baffle diverts the water flow in such manner that it reaches at neutralised velocity the impeller region. The cross sectional surface of the flow channel from the inlet opening tapers in the direction of the impeller position, with the incorporation of central conical bodies. Then it opens up to the original cross sectional surface at the outlet. With the braked speed of the impeller the kinetic weight of the closed water column has an optimal effect under pressure and suction conditions on the impeller blades, providing continuous work force for energy.

8580 Bayreuth, Lainecker-Straße 5 Beschreibung und Patentansprüche Titel: Kleinkraftwerk Anwendungs- Gewinnung sauberer Energie aus gebiet: Flüssen und Strömen Kritik des Einbezogen in das Feld der bestehenden großen Was-Standes der serkraftwerke einschließlich Gezeitenkraftwerke, Technik: unter Nutzung hoher Gefälle, großer Wassermengen und Gezeitenströmungen, bestehen bisher keine geeigneten technischen Anlagen, welche die Energie freifließender Flüsse und Ströme auswertend in nutzbare Energie freisetzen.8580 Bayreuth, Lainecker-Straße 5 Description and patent claims Title: Small power plant Application generation of clean energy from area: rivers and streams Criticism of being included in the field of the existing large water power plants including tidal power plants, technology: using high gradients, large amounts of water and tidal currents, there are currently no suitable technical systems that generate the energy evaluating free-flowing rivers and streams into usable energy.

Aufgabe: Der Erfindung liegt die Aufgabe zugrunde, diese umfangreiche natürliche Energiequelle in einfacher Technologie mit optimalem Wirkungsgrad derart freizulegen, daß weder ein allgemeines Sicherheitsrisiko, noch ein negativer Umwelteinfluß durch die Einbettung in die Strömung sowie durch die Inbetriebhaltung in Erscheinung tritt.Task: The invention is based on the task of this extensive natural energy source in simple technology with optimal efficiency such to reveal that neither a general safety risk nor a negative environmental impact through the embedding in the flow as well as through the maintenance in appearance occurs.

Lösung: Analog dieser Forderung kann ein relevant abgestimmtes Unterwasser-Kleinkraftwerk, schwimmfähig im Fluß als Strömungshindernis verankert und nur mit der Getriebe-und Generatorverkleidung außer Wasser stehend, wie aus der Zeichnung ersichtlich, nicht als störender Umweltfaktor eingestuft werden.Solution: Analogous to this requirement, a relevant coordinated underwater small power plant, buoyant anchored in the river as a flow obstacle and only with the gear and Generator cover standing out of water, as can be seen in the drawing, not classified as a disruptive environmental factor.

Als Schweißkonstruktion in Wahl alterungsbeständiger Stahlgüte, mit einfachem Riemengetriebe zum Generator, hoher Drehzahl des Flügelrades durch Venturirohr-Effekt bei kleineren Abmessungen und organischer Verschmelzung in der Schwimmkörperdurchbildung, kennzeichnen sich die Merkmale geringer Anlagekosten. As a welded construction in a choice of age-resistant steel quality, with simple belt drive to the generator, high speed of the impeller due to the venturi effect with smaller dimensions and organic fusion in the floating body formation, are characterized by the characteristics of low investment costs.

Unter dem Gesichtspunkt der Wirtschaftlichkeit konzipiert sich ein solches Kleinkraftwerk dahin, nur die schneller fließende Oberschicht, wie in der Zeichnung dargestellt, zur Umwandlung in freie Energie heranzuziehen. From the point of view of economic efficiency, a such a small power plant there, only the faster flowing upper class, like in that Drawing shown to be used for conversion into free energy.

Hierbei wird innerhalb der Eingangsöffnung die Strömung durch ein leicht nach unten geneigtes Leitblech derartig beeinflußt, daß sich die Geschwindigkeitsdifferenz bis zum Eintritt in den Flügelradbereich neutralisiert hat und die kinetiscne Wucht des Wassers egalisiert an die Flügel des Flügelrades absetzt. Here, the flow is through a inside the inlet opening slightly downwardly inclined baffle influenced in such a way that the speed difference until it entered the impeller area and neutralized the kinetic force of the water leveled off on the blades of the impeller.

Die Flügel des Flügelrades sind bei gleicher Steigung an Wurzel und Ende hydrodynamisch profiliert und unterliegen i Energieabgabe und Gangverzögerung, untor Druck- uiid Sogkraft stehend, den Massenkräften der geschlossenen Wassersäule des Durchflußkanals. The blades of the impeller are at the root and with the same pitch The end is hydrodynamically profiled and is subject to i energy release and gear delay, standing under pressure and suction force, the inertia forces of the closed water column of the flow channel.

Vorteile: Die Konzeption des Kleinkraftwerkes "MODUS" bildet in der Gesamtheit als Stromaggregat eine wichtige Ergänzung problemloser Energiegewinnung und ermöglicht unter geringem Aufwand auch im einzelnen eine hohe Wirtschaftlichkeit.Advantages: The conception of the small power plant "MODUS" forms in the The entirety as a power generator is an important addition to problem-free energy generation and enables a high level of economic efficiency with little effort.
