Design and Performance Optimization of Rectangular Air Duct Cleaning Robot

Abstract

The widespread adoption of central air conditioning systems has made pipe cleaning a key component in maintaining indoor air quality. However, traditional cleaning robots face numerous challenges that hinder their large-scale deployment. In this study, we designed a rectangular pipe cleaning robot and significantly improved its cleaning efficiency and adaptability by optimizing its motion mechanism, cleaning system, and control strategy. By applying the technical conflict analysis based on TRIZ theory, we abandoned the traditional driving method and adopted a semi-track motion system, ensuring excellent mobility performance. The cleaning system utilized an innovative self-suction technology, eliminating the space limitations associated with external vacuum devices and enhancing the robot's flexibility and cleaning effectiveness in narrow pipes. Additionally, the control system employed a fuzzy PID control strategy, ensuring stability and high efficiency in complex pipe environments. Simulation analysis demonstrated that this design scheme has made significant improvements compared to existing technologies, providing a solid theoretical foundation and technical support for the further development and wide application of related cleaning technologies.
