Device for Pushing Cameras Inside Pipes Resistant to Bending

This patent concerns a device for inserting working tools such as cameras into pipes through which fluid flows. The working tool is connected to a cable, near which a bending-resistant part is provided, and further another linear body is attached. These linear bodies extend outside the pipe and provide a secure seal inside and outside the pipe. The length of the bending-resistant part is adjustable, and the linear bodies can bend separately, allowing the working tool to be smoothly pushed even through curved parts of the pipe.

• Length adjustment mechanism for the bending rigidity enhancing section
• Separate bending operation of the linear bodies
• Structure that ensures operation while maintaining sealing

In conventional devices for working inside pipes, when pushing cameras or other tools through long distances or curved pipes, the cable tends to bend easily, causing pushing force to be poorly transmitted and often stopping midway. Additionally, moving the tool inside the pipe while preventing fluid leakage was difficult. This resulted in poor work efficiency and hindered smooth maintenance and inspection.

In this invention, a bending-resistant part is provided near the working tool's cable, to which another linear body is attached to effectively transmit the pushing force. Furthermore, the linear body extends outside the pipe, and a sealing structure prevents fluid leakage. The length of the bending-resistant part is adjustable, enabling optimization according to the pipe's curvature. This allows the working tool to be pushed through curved pipes without stopping.

• Technology to reduce pushing resistance at bends
• Technology for smooth introduction of long working tools
• Technology to prevent fluid leakage while ensuring operation
