A jewelry viewing stand including a stand, an imaging device, and an adjustable base is provided. The imaging device is configured to image a piece of jewelry and the stand is configured to hold and position the imaging device. The adjustable base is attached to the stand and positioned beneath the imaging device. The adjustable device is configured to move a piece of jewelry vertically toward and away from the imaging device while the stand maintains the imaging device in a stable, stationary position.

An imaging pod for capturing image data of a surface of a material stockpile, includes a housing including selectively a moveable door, an image sensor disposed within the housing and selectively revealeable responsive to the selective movement of the door. When the image sensor is revealed, the image sensor is configured to capture the image data of the surface of the stockpile.

The present invention discloses a movable visual inspection device for shield machines, comprising a rail and an inspection platform. The rail is installed on a shield tail, and the inspection platform includes a bottom plate, a shell, a cleaning mechanism, a power storage control system, and a traveling mechanism. Inside the shell is a visual inspection mechanism with a camera box, a camera, and a stabilizer component. The traveling mechanism drives the bottom plate along the rail. The cleaning mechanism, consisting of a glass sheet, a reel driving part, and a cleaning film, keeps the camera lens clear. The reel driving part rotates the cleaning film, which slides against the glass sheet on the camera box. This invention enables multi-faceted and multi-angle visual inspection of shield machine segments, ensures a clear camera lens, facilitates automatic cleaning and inspection position adjustment, and enhances working efficiency and inspection effectiveness.
