Abstract
(A1) Die Erfindung betrifft ein Aquarium mit einem druckdichten Aquariumsbehaelter (7-12), der im Betrieb mit einer Fluessigkeit gefuellt ist, sowie mit einer in den Aquariumsbehaelter (7-12) muendenden druckfesten Steigleitung (1) zur Erzeugung eines erhoehten hydrostatischen Drucks in dem Aquariumsbehaelter (7-12) durch eine in der Steigleitung (1) stehende Fluessigkeitssaeule.

 

WO 2009039928 A1 UPAB: 20090428 NOVELTY - The aquarium has a pressure-tight aquarium tank (7), which is filled with a liquid during operation. A pressure-resistant rising pipe (1) e.g. steel pipe, opens out into the aquarium tank, and produces an increased hydrostatic pressure in the aquarium tank by a liquid column located in the rising pipe. The aquarium tank is arranged in an underground mine e.g. coal mine. The rising pipe is upwardly extended over an earth surface for increasing hydrostatic pressure in the aquarium tank. A suction pump (22) is attached at a purge valve (21). USE - Aquarium i.e. deep sea aquarium, for accommodation and survey of a marine animal i.e. fish, in an underground mine i.e. coal mine. Can also be used for a public zoo. ADVANTAGE - The pressure-resistant rising pipe opens out into the aquarium tank and produces increased hydrostatic pressure in the aquarium tank by liquid column located in the rising pipe, thus separating function of pressurization from the aquarium tank, optimizing the aquarium tank and the pipe, avoiding extension of the aquarium tank over a large height difference, reducing manufacturing cost of the aquarium, and tempering the aquarium simply with small vertical extension as temperature-limited water movements are intensively reduced due to the small vertical extension. The aquarium is designed such that hydrostatic pressure in the aquarium is determined by height of the liquid column in the pipe, thus providing a small cross section for the pipe, reducing operational risk, and allowing small amount of liquid to leak during leakage or breaking of the pipe.
