Pipelines are connected by pipes, joints and valves, and are used to transport gas, liquid or fluid with solid particles. Pipes are widely used, mainly in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial installations. During long-term use or long-term idleness, rust will appear on the inner wall of the pipeline, resulting in uneven inner walls and flatness problems. At this time, a visual inspection device is required for inspection.

At present, the pipeline visual inspection device is mainly based on a single camera, which may cause incomplete sampling of the inner wall during inspection, and the shooting efficiency of a single camera is low, and the required rotation angle is too large, which is prone to the problem of low camera stability.

Although the controllability is guaranteed, the camera will be unstable during sampling, resulting in blurred images, and even requires secondary sampling, which is not efficient. . At the same time, the wear and tear of the inner wall of the pipeline is different, which will easily lead to poor sampling position of the camera in the pipeline, and the image size and definition will be different during image acquisition, which will affect the synthesis effect of the collected images later. Based on this, the utility model designs a new device for image acquisition of the inner wall of the pipeline to solve the above problems.
