Abstract

The system consists of several identical hydroelectric power stations (1) in sequence in the direction of water flow. The stations are arranged only in a part of the flow cross-section of the flowing water, e.g. outside the shipping channel (2) in the boundary area. The energy conversion reduces the flow rate of a relatively small, partial region and reduces the overall flow rate by a defined amount after mixing the reduced and unaffected flows.

Description

Oft sind Flußregulierungsmaßnahmen zur Gewährleistung einer geregelten Schifahrt mit erheblichen Eingriffen in das Flußbett verbunden.River regulation measures are often used to ensure a regulated Shipping associated with significant interventions in the river bed.

Die klassischen Regulierungen laufen im wesentlichen immer auf die bauliche Einengung des Gesamtquerschnittes hinaus, wobei bei gleicher Energiehöhe zumeist eine partiell größere Abflußgeschwindigkeit und damit größere Schleppkräfte an der Sohle entstehen, mit der Notwendigkeit von weiteren Verstärkungsmaßnahmen.The classic regulations always run on the structural narrowing of the overall cross-section, with the same Energy level mostly a partially higher discharge rate and thus greater tractive forces arise on the sole, with the need of further reinforcement measures.

Hauptgedanke der Erfindung ist die Anordnung von den Wasserabfluß bremsenden, energieumsetzenden Einrichtungen, das sind Einzelwasserkraftanlagen (1) z. B. vornehmlich in den Randbereichen (3) neben der Schifffahrtsrinne (2).The main idea of the invention is the arrangement of the water drainage braking, energy converting devices, that are individual hydropower plants ( 1 ) z. B. mainly in the edge areas ( 3 ) next to the shipping channel ( 2 ).

Die Funktionsweise beruht auf einer schrittweisen Reduzierung der Strömungsgeschwindigkeit durch Abführen der Fließenergie mittels hintereinander angeordneter Turbinenstufen.The way it works is based on a gradual reduction in Flow rate by dissipating the flow energy by means of turbine stages arranged one behind the other.

Mit einer Turbinenstufe kann die durch ihren Querschnitt durchströmende Wassermenge auf etwa 1/3 ihrer Geschwindigkeit reduziert werden. With a turbine stage, the one that flows through its cross section Water volume can be reduced to about 1/3 of their speed.  

Soll z. B. ein aus einem Rechteckquerschnitt (Schifffahrtsrinne) (2) von einer Tiefe von 2,4 m und einer Breite von 50 m und zwei Dreieckquerschnitten (3) von je 0,5 × 2,4 m × 20 m Fläche bestehender Flußquerschnitt von 168 m2 hinsichtlich seiner Wassertiefe verbessert werden, und wird dabei eine Tiefe von 2,90 m angestrebt, wird der Querschnitt um ca. 0,5 m × 90 m = 45 m2 vergrößert auf ca. 213 m2.Should z. B. from a rectangular cross-section (navigation channel) ( 2 ) of a depth of 2.4 m and a width of 50 m and two triangular cross-sections ( 3 ) each 0.5 × 2.4 m × 20 m area existing river cross-section of 168 m 2 are improved with regard to its water depth, and if a depth of 2.90 m is aimed for, the cross section is increased by approx. 0.5 m × 90 m = 45 m 2 to approx. 213 m 2 .

Aus Gründen der Kontinuität ergibt sich die nun zu reduzierende Fließgeschwindigkeit zu
For reasons of continuity, the flow rate to be reduced now arises

Wendet man die erfindungsgegenständliche Maßnahme an, mit Einzelwasserkraftanlagen mit einem Einlaufquerschnitt von 8,0 m2 und reduziert die Durchströmgeschwindigkeit auf ein Drittel, so ergibt sich nach der Durchmischungsstrecke
If the measure according to the invention is applied, with individual hydropower plants with an inlet cross section of 8.0 m 2 and the throughflow speed is reduced to a third, this results after the mixing section

Um also den beabsichtigten Effekt einer Erhöhung des Wasserstandes um 0,5 m zu erzielen, sind
In order to achieve the intended effect of increasing the water level by 0.5 m

9 Einzelwasserkraftanlagen beschriebener Größe erforderlich. 9 individual hydropower plants of the size described required.  

Eine effektivere Durchmischung mit Verkürzung der Vermischungsstrecke (4) wird durch eine asymmetrische Formgebung der Einzelturbinenanlage erreicht, deren Auslaufquerschnitt stärker zur Stromachse orientiert ist als ihr Einlaufquerschnitt und so die Wassermenge schneller dem Hauptstrom wieder zuführt.A more effective mixing with shortening the mixing section ( 4 ) is achieved by an asymmetrical shape of the individual turbine system, the outlet cross-section of which is more oriented to the flow axis than its inlet cross-section and thus the amount of water is returned to the main flow more quickly.

Da nach dem Abbremsen der Fließgeschwindigkeit bei den gegebenen Gefälleverhältnissen wieder eine Beschleunigung einsetzen würde, ist auch diese potentielle Energie entsprechend abzubauen, was eine Weiterführung einer gewissen Anzahl von Anlagen pro Längeneinheit je nach örtlichen Verhältnissen erforderlich macht. Because after braking the flow rate at the given Slope conditions would again use an acceleration is too depleting this potential energy accordingly, which is a continuation a certain number of systems per unit length depending on the local conditions.
