Description

Transportables Video-Kamerasystern zur Inspektion von Rohren, Kaminen und anderer Hohlkörper ab 55 mm Querschnitt.Portable video camera system for inspecting pipes, chimneys and other hollow bodies with a cross-section of 55 mm or more.

Videoanlagen werden heutzutage vielseitig eingesetzt. Gebäudeschutz, Türsicherung usw. Im transportablen Bereich sind die sogenannten Kamkorder weit verbreitet. Im Bereich der Inspektionskameras für Rohre sind sehr aufwendige Konstruktionen mit eigenem Antrieb für die waagerechte Fortbewegung bei der Kanalinspektion im Einsatz.Video systems are used in many different ways nowadays. Building protection, door security, etc. In the portable sector, so-called camcorders are widely used. In the area of inspection cameras for pipes, very complex constructions with their own drive for horizontal movement are used for sewer inspection.

Der im Schutzanspruch 1 angegebenen Erfindung liegt die Anforderung zugrunde, ein preiswertes transportables Videosystem zu schaffen, mit deren Hilfe Kamine, Abgasrohre usw. mit kleinen Querschnitten ohne Fremdlicht Vorort an Gebäuden kontrolliert werden können. Diese Kontrolle ist hilfreich bei Neuabnahmen und dient zur Feststellung des Versottungsgrades nach längerer Benutzung. Außerdem verlangt der Gesetzgeber im Bereich der Asbestkamine schärfere Kontrollen des Bauzustandes.The invention specified in claim 1 is based on the requirement to create an inexpensive, portable video system with the help of which chimneys, exhaust pipes, etc. with small cross-sections can be inspected on site on buildings without external light. This inspection is helpful for new inspections and serves to determine the degree of sooting after prolonged use. In addition, the legislator requires stricter inspections of the structural condition of asbestos chimneys.

Das Videosystem nach Schutzanspruch 1 erfüllt diese Anforderungen ideal.The video system according to claim 1 meets these requirements ideally.

Durch den Schwenkbereich innerhalb der vorderen Gehäusekappe (Abb.2 u. 3) können Fugen, Dichtungen und Seitenwende exakt kontrolliert werden. Das Kameraobjektiv (5) wird dabei so dicht unter der transparenten Gehäusekappe (1) geführt, so daß die mitgeführten Lichtquellen (3) keine Reflektionen erzeugen, die in das Objektiv zurückfallen können. Die Gehäuseform bleibt beim schwenken unverändert, dies ist wichtig für die mechanische Belastbarkeit. Auch Verschmutzungen, im vorgesehenen Einsatzgebiet besonders stark, können die Mechanik nicht erreichen, und lassen sich leicht vom runden Kameragehäuse entfernen.The swivel range within the front housing cap (Fig. 2 and 3) allows joints, seals and side turns to be precisely controlled. The camera lens (5) is guided so closely under the transparent housing cap (1) that the light sources (3) do not create any reflections that could fall back into the lens. The housing shape remains unchanged when swiveling, which is important for mechanical resilience. Even dirt, which is particularly heavy in the intended area of application, cannot reach the mechanics and can be easily removed from the round camera housing.

Das im Schutzanspruch 2 ausgeführte 9 mm dicke Kabel (7) erlaubt die achsiale Kontrolle der Kamera.The 9 mm thick cable (7) described in claim 2 allows axial control of the camera.

Das Kameraobjektiv besitzt einen Bildeinfallswinkel (2) von 80° und wird um 170° geschwenkt (4). Hierdurch ergibt sich ein Gesamtbereich von 250°. Es ergeben sich aber auch zwei Bereiche in Schwenkachsen-Richtung die nicht eingesehen werden. Diese lassen sich aber leicht einsehen, wenn die Kamera mittels des dick ausgeführten Kabels (7) in Achsialrichtung gedreht wird. Dies hat sich im Test als sehr praktisch erwiesen, da die Kamera ohnehin an dem Kabel von Hand geführt wird. Der Aufwand, das Kameraobjektiv um eine zweite Achse schwenkbar zu machen, entfällt somit.The camera lens has an angle of incidence (2) of 80° and is swiveled by 170° (4). This results in a total range of 250°. However, there are also two areas in the swivel axis direction that cannot be seen. These can be easily seen, however, if the camera is rotated in the axial direction using the thick cable (7). This proved to be very practical in the test, since the camera is guided by the cable by hand anyway. The effort of making the camera lens swivel around a second axis is therefore eliminated.

Der im Schutzanspruch 3 ausgeführte Transportkoffer besteht aus vielen bekannten Einzellösungen, die aber in der aufgeführten Zusammensetzung dazu beitragen, aus der Kamerakonstruktion ein wartungsfreies, leicht zu bedienendes, transportables Video-Inspektionssystem zu machen.The transport case described in claim 3 consists of many known individual solutions, which, however, in the composition listed, contribute to turning the camera construction into a maintenance-free, easy-to-use, transportable video inspection system.
