BNCT Target Section Locking Structure for Fast Vacuum-Line Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection between the target section and the vacuum pipeline in BNCT systems is time-consuming and labor-intensive, posing difficulties in replacement and maintenance, especially in radiated or narrow spaces.
Innovation Solution
A quickly assemblable and disassemblable target part connecting structure using a locking device with a lock body, lock rod, and driving mechanism, allowing for rapid connection and disconnection through telescopic movement of the lock rod along the axial direction, facilitated by a linear motor, hydraulic cylinder, or pneumatic cylinder.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vacuum flanges with bolts and nuts are used to connect the target section and pipeline section, then the connection is reliable and secure, but the assembly and disassembly process becomes time-consuming and labor-intensive
Solution Approach 1:
The locking device is divided into multiple functional components: a lock body with locking pins, a lock rod with guide faces, and a driving mechanism. This segmentation allows each component to perform its specific function efficiently, enabling rapid locking and unlocking while maintaining secure connection
Solution Approach 2:
The locking pins are designed to be movable rather than fixed, allowing them to extend radially to engage with the lock rod and retract when needed. The driving mechanism dynamically controls the lock rod's position, enabling quick transition between locked and unlocked states while maintaining reliable connection during operation
2Strength
If multiple bolts are used for manual tightening to achieve secure connection, then the connection strength is sufficient, but the operation becomes inconvenient in radiated space or narrow space
Solution Approach 1:
The driving mechanism automatically performs the locking action by driving the lock rod to extend or retract the locking pins into engagement with the lock body. This self-service mechanism eliminates the need for manual bolt tightening, making operation convenient even in radiated space or narrow space while maintaining sufficient connection strength through the engineered locking pin engagement
3Device complexity
If traditional locking mechanisms are used, then the structure is simple, but the replacement of target section and maintenance of vacuum system becomes difficult
Solution Approach 1:
The locking device is designed as a separable unit that can be easily removed from the vacuum pipeline system. The driving mechanism can be extracted to replace the target section, and the locking pins can be disengaged by simply retracting the lock rod, making maintenance and replacement operations straightforward while keeping the overall device complexity manageable
