Description

Es ist bekannt, Fischtreppen in Betonbauweise in Wasserverbauungen bzw., Fischaufzüge zu montieren.It is known to fish stairs in concrete construction in water engineering or, fish lifts assemble.

Die vorliegende variable Vorrichtung besteht aus einem Trogsystem, welches ein außen montiertes bewegliches Scherensystem besitzt, welches selbstregulierend auf Wasserstandsveränderungen reagiert.The present variable device consists of a trough system, which is an outside mounted movable scissors system, which is self-regulating Water level changes reacted.

Das Trogsystem ist schwimmfähig.The trough system is buoyant.

Seine inneren Durchlässe sind strömungstechnisch so gestaltet, daß Fischwanderungen erfolgen können.Its internal passages are fluidically designed so that fish migration can be done.

Der im Patentanspruch 1 angegebenen Erfindung liegt das Problem zugrunde, die Vielzahl von aufwendigen Bauvorhaben zu reduzieren und ein einheitliches, einer DIN - Norm zugeordnetes, im Baukastensystem anzufertigendes und damit kostengünstiges und umweltgestaltendes Produkt zu fertigen.The invention specified in claim 1 is based on the problem, the multitude of to reduce complex building projects and a uniform, one DIN standard assigned, to be produced in the modular system and thus inexpensive and to manufacture an environmentally friendly product.

Dieses Problem ist durch die variable schwimmfähige Bauweise gelöst.This problem is solved by the variable floating design.

Der Vorteil besteht in einer einheitlichen, kostengünstigen Fertigung, einer geringen Wartung, geringem Transportaufwand durch das Zusammenschachteln der einzelnen Baugruppen, und damit verbunden, dem Containertransport.The advantage is a uniform, inexpensive production, low maintenance, low transport costs due to the nesting of the individual assemblies, and associated with container transport.

Ein Ausführungsbeispiel ist in der Zeichnung aufgeführt. (teilausgefahren)An embodiment is shown in the drawing. (partially extended)
