Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for removing plugging from pipes risk causing fires or explosions when combustible gases or liquids are present due to the generation of static electricity, necessitating a more stable and spark-free operation.
Innovation Solution
A drill apparatus with a bronze drill blade, bevel and worm gears, and a flexible high-pressure hose system that allows for precise removal of plugging with minimal force while preventing sparks, using nitrogen gas to suppress potential fires or explosions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a welding rod is used to remove plugging from a pipe, then the plugging can be removed, but static electricity is generated causing sparks and fire hazards
Solution Approach 1:
The patent replaces the welding rod method with a drill blade mechanism that uses mechanical rotation and impact to break plugging. The drill blade is rotated by a motor and driven into the plugging through a punching mechanism, eliminating the need for welding operations that generate sparks and static electricity.
Solution Approach 2:
The patent introduces a nitrogen gas supply system that fills the pipe interior with nitrogen gas before and during the plugging removal operation. This creates an inert atmosphere that prevents combustion even if sparks are generated, thereby eliminating the fire hazard associated with using welding rods in pipes containing combustible gases or liquids.
2Productivity
If conventional plugging removal methods are used in pipes with combustible materials, then plugging can be removed, but fire or explosion accidents may occur
Solution Approach 1:
The patent supplies nitrogen gas into the pipe interior before the plugging removal operation begins. This preliminary action replaces the combustible atmosphere with an inert nitrogen atmosphere, ensuring that even if the drill blade generates sparks during operation, no fire or explosion can occur. The nitrogen supply is maintained throughout the entire plugging removal process.
Solution Approach 2:
The patent creates a safe operating environment by filling the pipe interior with nitrogen gas, an inert atmosphere that cannot support combustion. This allows the drill blade to efficiently remove plugging through mechanical means without the risk of fire or explosion, thereby maintaining both high productivity and reliability.
3Productivity
If a drill blade is used to remove plugging, then plugging can be broken effectively, but the drill blade may get stuck in the pipe
Solution Approach 1:
The patent designs the drill blade with a rotating motion controlled by a motor and transmission mechanism. The rotation speed and torque can be adjusted to match the hardness and quantity of plugging. This dynamic control allows the drill blade to effectively break plugging while reducing the risk of getting stuck, as the rotational motion prevents the blade from becoming lodged in the broken material.
Solution Approach 2:
The patent employs a punching mechanism that applies concentrated force to push the drill blade into the plugging in stages. This segmented approach allows controlled advancement of the drill blade, preventing it from becoming stuck by distributing the force application over multiple controlled movements rather than a single aggressive thrust.
