Tube Locking Device for Fire Sprinkler Seismic Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sprinkler mounting instruments for fire suppression systems face challenges in maintaining a secure connection between the sprinkler reducer and support tube during seismic events, leading to potential separation and increased installation time due to design limitations and vibration-induced movement.
Innovation Solution
A tube locking and releasing device featuring a seating structure with curved seating walls and cover walls, a fixing structure with a handle mechanism, and a pressing structure with friction wings and gear tooth contact portions, ensuring a secure, one-touch connection between the sprinkler reducer and support tube, preventing rotation and separation during building vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the push module is fitted to the guide groove of the bracket body, then the sprinkler combining instrument can be inserted, but during vibration of a building, the push module is easily spaced apart from the bracket body, causing separation of the support and sprinkler combining instrument
Solution Approach 1:
The patent employs curved guide grooves and corresponding curved guide surfaces on the push module that match the curvature of the bracket body. This curved geometry ensures continuous contact between the push module and bracket body during vibration, preventing separation while maintaining structural simplicity. The curved surfaces allow the push module to follow the vibrational movements without disengaging from the guide groove.
2Ease of operation
If the cover covers the bracket body, then the push module length is restricted by contact of the cover with the bracket body and sprinkler combining instrument, but before the cover covers, the length must be adjusted according to size changes of the sprinkler combining instrument
Solution Approach 1:
The patent incorporates a pre-adjustable push module with telescopic or adjustable-length sections that can be configured to match different sprinkler combining instrument sizes before installation. The cover and bracket body are designed with pre-positioned contact points that automatically set the correct push module length during the covering operation, eliminating the need for manual adjustment after installation begins.
Solution Approach 2:
The push module features variable length capability through telescopic sections or interchangeable segments. The system allows the push module length parameter to be changed according to the specific size of the sprinkler combining instrument being installed, enabling adaptation to different configurations without requiring complete disassembly or complex adjustment procedures.
3Force
If the push module has a structure to push the sprinkler combining instrument toward the support, then connection can be achieved, but the shape of the bracket body and diameter of the sprinkler combining instrument make it difficult to push
Solution Approach 1:
The patent employs an asymmetric push module design where the pushing surface is shaped to match the specific geometry of the sprinkler combining instrument. The push module features a tapered or contoured pushing end that conforms to the instrument's diameter and shape, distributing the pushing force evenly across the contact surface. This asymmetric configuration enables effective pushing without requiring excessive force or complex mechanical advantage mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device effectively maintains a close contact force between the sprinkler reducer and support tube, preventing separation and reducing installation time by ensuring a secure, elastic connection that withstands building vibrations, enhancing the seismic resilience of fire suppression systems.
