AI Technical Summary

Technical Problem

Current technologies rely on manual labor for pipeline inspection and cleaning, which is inefficient and poses high safety risks. Furthermore, traditional equipment is poorly adaptable to pipelines with multiple bends and diameter changes, making it difficult to meet the needs for accurate inspection and efficient cleaning.

Method used

A pipe inspection and cleaning robot, comprising a brushing mechanism and a support mechanism, was designed. Equipped with a miniature high-definition inspection camera, it adopts a multi-functional combined cleaning technology, combining a lead screw motor and sensors to achieve adaptive diameter adjustment, enabling stable support and efficient cleaning in complex pipes.

Benefits of technology

It achieves efficient integration of pipeline inspection and cleaning, significantly improving operational efficiency, reducing safety risks, and ensuring comprehensive coverage and cleaning results for pipelines with multiple bends and diameter changes.

Abstract

This utility model discloses a robot for pipeline inspection and cleaning, including a scrubbing mechanism and three support mechanisms. The three support mechanisms are connected in pairs via connecting springs. Spring clamping plates A and B respectively press the two ends of the connecting springs into the gap between the flange fixing plate and the lead screw motor support base. The scrubbing mechanism is connected and fixed to the first support mechanism via an elastic connecting shaft and a nut. The tail of the last support mechanism is equipped with a battery pack and a bottom main control unit. Water pipes and electrical wires are connected to the device through flange A. This utility model solves the problems of existing pipeline inspection and cleaning methods, such as the numerous hidden dangers of manual handling, low cleaning efficiency, unsatisfactory results, and the reliance on manual experience for the inspection and cleaning of pipes with multiple bends and diameter changes.
