Multiple Pipe Systems

Multiple Pipe Systems

Multipipe systems consist of complex configurations of interconnected pipes designed to transport fluids efficiently across intricate networks. They are essential in engineering applications requiring precise control over flow distribution, pressure, and head loss. They are categorized into series, parallel, loop, and network configurations, each distinguished by unique flow characteristics and applications.
Series Configuration
In a series configuration, fluid flows sequentially from one pipe...

Area of Science:

Robotics
Mechanical Engineering
Industrial Automation

Background:

Pipeline maintenance is critical for preventing leaks in industrial and residential settings.
Buried pipelines necessitate the development of internal inspection robots.
Existing in-pipe robots often face challenges in navigating complex geometries and require sophisticated control systems.

Purpose of the Study:

To introduce a novel in-pipe robot design utilizing Continuously Variable Transmission (CVT) mechanisms.
To enable robust navigation of various pipe types, including vertical and curved sections.
To simplify robot control by eliminating the need for active control of individual wheels.

Main Methods:

The robot incorporates one air motor, three CVT mechanisms, and six wheels attached to slider-crank mechanisms (three active, three idler).
A slider-crank and spring mechanism generates wall press force for enhanced traction.
CVT mechanisms passively adjust speed ratios for independent, continuous wheel speed control.

Main Results:

MATLAB simulations and experimental validation confirmed the robot's effectiveness.
The robot successfully navigated curved pipes.
Achieved a maximum speed of 17.5 mm/s and a maximum traction force of 56.84 N.

Conclusions:

The proposed in-pipe robot with CVT mechanisms offers a simplified yet effective solution for pipeline inspection.
The design facilitates navigation through diverse and challenging pipe configurations.
This technology holds promise for improving the efficiency and safety of pipeline maintenance.
