Sewer pipe repair device

Sewer Pipe Repair Device

This technology is a gate-type structure designed for the repair and inspection of sewer pipe inner walls. It features a mobile platform integrated with a frame consisting of horizontal and vertical components, allowing for autonomous movement. A mobile unit equipped with repair and inspection modules travels along rails installed on the frame to perform tasks.

Repairing aging concrete in sewer pipes poses significant safety risks to workers, including suffocation, electric shock, and falls. Furthermore, the need for automation is increasing due to a shortage of skilled labor and declining labor productivity.

This technology features a mobile platform for navigating the sewer floor, a rail structure capable of adjusting to the pipe's cross-sectional shape for omnidirectional repair and inspection, a depth control unit for enhanced efficiency, and sensor-based algorithms for leveling and distance control. Applicable to logistics, service robots, and autonomous platforms, it replaces manual labor with robotics for sewer pipe maintenance, significantly improving both operational efficiency and safety.

Key Features:

• A frame assembly comprising a horizontal frame facing the ceiling of the sewer pipe and a pair of vertical frames coupled to both ends of the horizontal frame, extending downward to face the side walls of the sewer pipe.
• A mobile rail assembly that mirrors the shape of the frame assembly, positioned at a distance from it, partially connected to the frame, and featuring rails formed along its longitudinal direction.
• An inspection module coupled to the mobile unit that monitors the quality of the repair work or the condition of the sewer pipe's inner wall.
• A repair module coupled to the mobile unit that performs repairs on the ceiling and walls of the pipe.
