Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If visual inspection devices are fixedly installed on the shield machine, then the device structure is simple, but the inspection range and flexibility are limited
Solution Approach 1:
The inspection platform is designed to move along the rail through the traveling mechanism, transforming the fixed inspection device into a dynamic one. The bottom plate with wheels can travel along the rail mounted on the shield tail, allowing the camera to inspect different positions and angles of the segment, thereby improving inspection range and flexibility while maintaining relatively simple device structure
2Productivity
If manual cleaning of camera lens is performed, then the device structure is simple, but the working efficiency and inspection effect are restricted
Solution Approach 1:
The cleaning mechanism is designed to automatically clean the camera lens without manual intervention. The cleaning film is fed through the film feeding mechanism and contacts the lens to remove dust and contaminants automatically during the inspection process, improving working efficiency and inspection effect while adding only moderate complexity to the device structure

AI summary
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.
