The present disclosure relates in general to a diagnostic device for inspection of an enclosed tube system, and more particular, capability to obtain images or video of the interior of the enclosed tube system while a diagnostic camera apparatus is attached to a moveable member and traveling through the enclosed tube system.
Inspecting an enclosed tube system with a camera is a useful technology. The use of a camera for inspection allows its user to identify potential or actual problems within the interior of the system. Occasionally, there will be a problem in the system that causes the system not to work properly, and a repair will need to be made quickly to prevent downtime. As such, a camera for inspection allows direct identification of debris or system defects, as well as the location of the debris or defects in the system.
Currently, obtaining such information from the enclosed tube system requires that a generic low-cost camera is attached to a cable and fed through an enclosed tube system. However, there are issues when using this technique. One issue is the cameras utilized in such inspections do not provide adequate frame rate relative to the speed of movement of the camera. Also, cameras utilized in such inspections do not provide clear imaging of the interior of the enclosure due to the poor quality of the captured images. Another issue is that the light used by the camera to illuminate the enclosure is a single un-diffused illumination light-emitting diode (LED), which does not provide consistent illumination and contributes to the difficulty in providing clear images of the enclosure tube interior for debris location identification or enclosure tube defect recognition. Another issue is that current cameras utilize small size coin cell batteries and the camera run time is limited. These batteries are also difficult to replace because they are soldered or insecurely clipped in place. Another issue is that the cameras utilized in such inspections are secured using multiple parts, fasteners, and a tool, meaning that switching the unit to another enclosed tube system is time-consuming and cumbersome. Finally, the cameras utilized in such inspections build up internal heat during operation, initiating thermal shut down until the camera is able to be cooled, which severely limits the runtime and therefore the number of images captured.
Accordingly, there is a need for a diagnostic camera apparatus to help diagnose problems in an enclosed tube system that provides high-quality images, proper illumination, long battery life, easy installation and removal process, and defense against building up internal heat during operation.
Disclosed herein are systems, methods and devices for a diagnostic device for inspection of an enclosed tube system, and more particular, capability to obtain images or video of the interior of the enclosed tube system while a diagnostic camera apparatus is attached to a moveable member and traveling through the enclosed tube system.
