Pipeline Hose Drum Control Using Movement Direction Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pipeline cleaning and inspection systems face challenges in efficiently handling hoses, particularly in terms of winding and unwinding, which can be cumbersome and prone to leaving hoses lying around, increasing the risk of tripping and reducing efficiency.
Innovation Solution
A system and method that utilizes a sensor-equipped working device to detect movement direction and speed, coupled with a control device and motor to automatically wind or unwind the hose based on detected movement direction and speed, facilitating seamless handling of the hose during cleaning and inspection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the hose is manually unwound and wound using a motor, then the hose handling process is simplified, but the risk of hoses being left lying around increases, creating tripping hazards and reducing operational safety
Solution Approach 1:
The system uses sensor devices to detect the movement direction of the working device and provides feedback to the control device, which automatically controls the motor to wind or unwind the hose accordingly. This closed-loop feedback mechanism ensures the hose is always properly managed, eliminating the risk of hoses being left lying around while maintaining ease of operation.
Solution Approach 2:
The system performs hose winding and unwinding automatically based on detected movement directions, without requiring continuous manual intervention. The motor-driven hose drum self-regulates the hose management based on operational conditions, improving both safety and operational efficiency.
2Adaptability or versatility
If the hose is manually handled during cleaning and inspection, then flexibility is maintained, but time is lost due to cumbersome winding and unwinding operations
Solution Approach 1:
The system replaces manual mechanical hose handling with an automated motor-driven hose drum controlled by sensor-based detection. This substitution maintains the flexibility needed for pipeline navigation while dramatically reducing the time required for winding and unwinding operations, as the motor automatically responds to detected movement directions.
3Productivity
If automated hose winding is implemented based on movement detection, then operational efficiency is improved, but device complexity increases due to additional sensors and control mechanisms
Solution Approach 1:
The sensor devices serve multiple functions: they detect movement direction for automated hose control, and can simultaneously provide data for pipeline inspection and navigation. The control device integrates multiple control functions in a single unit, reducing overall system complexity while maintaining high productivity through automated operations.

AI summary
A system for cleaning and/or inspecting a pipeline includes a hose and a working device connected to one end of the hose. The working device includes a sensor device for detecting sensor data representing a movement direction of the working device in the pipeline, a hose drum for winding and unwinding the hose, a motor coupled to the hose drum and configured to rotate the hose drum so as to wind the hose onto the hose drum, and a control device connected to the working device and motor and to determine the movement direction of the working device in the pipeline on the basis of the sensor data and to output to the motor a first control signal which causes the motor to rotate and wind up the hose when the determined movement direction of the working device corresponds to a predetermined first movement direction.
