Gas Flow Inspection Fixture for Connection Leak Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection systems for gas flow in container storage facilities fail to accurately detect abnormalities in the placement table or misalignment of containers due to improper connections between gas supply and exhaust sections and their respective inspection units.
Innovation Solution
An inspection system that includes an inspection unit with connectable inflow and outflow sections, capable of measuring flow rates and determining leakage based on differences between supply/exhaust flow rates and measured inflow/outflow rates, allowing for proper connection verification without a container present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If gas flow inspection is performed based on sensor detection in the exhaust pipe, then gas flow can be monitored, but connection abnormalities between gas supply section and container cannot be detected
Solution Approach 1:
An inspection container is introduced as an intermediary device between the gas supply section and the actual container. This inspection container includes an inspection inflow section connectable to the gas supply section and an inspection outflow section connectable to the gas exhaust section. By using this intermediary inspection container, the system can detect connection abnormalities at the junction points without requiring direct access to the container-container interface, thus resolving the contradiction between monitoring gas flow and detecting connection issues.
Solution Approach 2:
The inspection container is positioned and connected to the gas supply and exhaust sections before the actual container is processed. This preliminary setup allows the inspection system to verify proper connection between the gas supply section and the container inflow section, as well as between the gas exhaust section and the container outflow section, before gas processing begins. The inspection container serves as a testbed to ensure proper connections are established.
2Productivity
If gas is continuously supplied to the container, then gas flow can be maintained, but gas leaks from the gap between main body and lid
Solution Approach 1:
The inspection system implements a feedback mechanism by continuously monitoring the gas flow rate through the inspection container using a flow rate meter. The system compares the supplied gas flow rate with the actual flow rate through the inspection container, and when a discrepancy is detected indicating a leak or connection problem, the system can alert operators or automatically adjust the gas supply. This feedback loop enables continuous gas supply while preventing harmful gas leakage by detecting and responding to abnormal conditions.

AI summary
An inspection system inspects a flow of gas in a container storage facility that includes a placement table and a gas supply device to supply gas to the container. The inspection system includes: an inspection unit placeable on the placement table, and a determiner. The gas supply device includes: a gas supply section located in the placement table to be connectable to the container inflow section of the container; a gas supply pipe; and a supply gas flow rate controller to control a flow rate of the gas supplied to the gas supply section through the gas supply pipe, so as to be equal to a predetermined supply gas flow rate. The inspection unit includes: an inspection inflow section connectable to the gas supply section, and an inflow rate measurer to measure an inflow rate of the gas flowing thereto from the inspection inflow section.
