Description

Technical Field

[0001] The utility model belongs to the field of welding, and in particular relates to a high-temperature resistant camera device welded inside a pipeline. Background Art

[0002] When welding stainless steel, the thickness and material properties of the plate determine the welding method, while the customer's specific requirements also determine the welding difficulty. When the plate thickness reaches a certain level, single-sided welding is no longer sufficient, so we utilize double-sided welding. Double-sided welding of different diameters can be affected by the intensity of the red line on the back of the internal weld (outside the pipe), the operator's viewing angle, and visual fatigue. This can sometimes lead to internal weld deviation due to delayed judgment or visual errors. Monitoring and tracking internal welds has always been a concern. When welding low-grade, thin-walled steel pipes, the operator can monitor the internal weld by observing the red line on the back of the internal weld (outside the pipe). However, when the temperature reaches a certain level or the minimum diameter of the pipe is being welded, visual observation alone or conventional camera monitoring and tracking is no longer effective. If the welding trajectory cannot be detected and tracked immediately during welding, various problems such as welding deviation, welding penetration, and failure to timely follow up on welding parameters will occur. This will lead to unstable steel pipe forming and a larger meshing gap in the steel pipe forming, which is prone to burn-through and light leakage, resulting in quality defects such as burn-through.

The protective sleeve is a sleeve-shaped structure, including an outer tube and an inner tube. The outer tube and the inner tube are welded and sealed at both ends to form a water-cooling jacket. The tail end of the inner tube extends out of the outer tube, and the tail end of the inner tube is closed. The tail end of the outer tube is provided with a water inlet and a water outlet, and the tail end of the inner tube is provided with an air inlet; the camera includes a camera probe, a fixture, and a data cable. The camera probe is cylindrical and is fixed to the head end of the inner tube by a fixture. The fixture is provided with several ventilation holes. One end of the data cable is connected to the camera probe, and the other end is led out from the tail end of the inner tube. Utility Model Content

The camera 12 is aimed at the inside of the pipe and displayed by connecting to an external display screen. The camera 12 is adjusted to the welding position through the rotating structure 15 according to the welding position. Since the temperature is high during welding and the flow in the space inside the pipe is slow, the camera device 14 is cooled by the cooling structure 16 to ensure that the camera device 14 operates normally without damage.
