Gas Analysis Device Alignment Mechanism for Cantilevered Probe Deflection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas analysis devices face challenges in beam alignment due to positional deviations caused by the weight of components, particularly in explosion-proof areas like boiler flues, where opening the container to adjust the light source and reception device is not permitted, making it difficult to achieve proper beam alignment without compromising safety.
Innovation Solution
A gas analysis device with an alignment mechanism that includes an insertion member to move the light source or light reception device within the container along the X-Y plane, allowing for beam alignment without opening the container, using alignment shafts and floating bases to adjust the position and orientation of the light source and reception device relative to the probe, ensuring accurate laser beam alignment while maintaining the container's airtightness and explosion-proof integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the light source and light reception device are arranged in a container attached in a cantilevered manner, then the device can be installed at the measurement site, but the positions and orientations of the light source and light reception device deviate from design values due to weight deflection
Solution Approach 1:
The patent introduces an alignment mechanism with adjustment members that enable dynamic repositioning of the light source and light reception device within the container. This allows the system to adapt to deflection caused by cantilevered installation while maintaining proper beam alignment, resolving the contradiction between installation adaptability and alignment precision.
2Manufacturing precision
If the container is opened to adjust the positions of the light source and light reception device, then beam alignment can be performed, but it is not permitted in explosion-proof areas like boiler flues
Solution Approach 1:
The patent introduces an alignment mechanism that acts as an intermediary system, allowing beam alignment to be performed through the container wall without opening the container. The adjustment members extend through the container to enable position adjustment of the light source and light reception device while maintaining the explosion-proof integrity of the container.
3Adaptability or versatility
If the probe is attached in a cantilevered manner to the inside of the flue, then the reflection body can be positioned inside the flue, but the probe deflects by its own weight causing position and orientation deviation
Solution Approach 1:
The alignment mechanism with adjustment members enables dynamic compensation for probe deflection. By allowing position adjustment of the light source and light reception device within the container, the system can adapt to changes in reflection body position caused by probe deflection, maintaining proper beam alignment despite installation flexibility.
