Abstract

Wenn das Kamerasystem zur Untersuchung von Rohrleitungen mit Hilfe einer Schiebestange durch die Rohrleitung vorgeschoben wird, neigt das Kameragehäuse vor allem beim Durchgang durch gekrümmte Rohrabschnitte dazu, sich unkontrolliert um seine Längsachse zu drehen. Damit die in dem Gehäuse angeordnete Kamera dennoch stets seitenrichtige und aufrechte Darstellungen auf dem angeschlossenen Monitor liefert, ist der Kameramodul um die Längsachse des Gehäuses drehbar gelagert und mit einem Gewichtskörper versehen, dessen Schwerpunkt bei waagerechter Lage der Kamera unter der Drehachse liegt. Hierdurch nimmt die Kamera auch bei Verdrehung des Gehäuses stets die waagerechte Position ein.
