Battery Rack Fire Pipe Retention for Accurate Spray Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage systems face challenges in maintaining the correct position and orientation of fire extinguishing pipes, leading to inefficient fire suppression and potential damage due to interference with battery modules.
Innovation Solution
The energy storage system incorporates a guide rail with a fire extinguishing pipe and a heat detection member, along with anti-detachment members, including slits and stoppers, to secure the pipe in place and prevent rotation or detachment, ensuring reliable fire suppression performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the fire extinguishing pipe is made rotatable or detachable for flexibility, then the ease of operation is improved, but the reliability deteriorates due to potential detachment or incorrect positioning
Solution Approach 1:
The positioning system is segmented into multiple independent components: guide rails for linear positioning, anti-detachment members for securing the pipe, and heat detection members for thermal response. Each segment performs a specific function to collectively ensure reliable positioning while maintaining operational flexibility.
Solution Approach 2:
The guide rails and anti-detachment members are pre-installed on the rack frame to establish the correct positioning path and constraints for the fire extinguishing pipe before any fire event occurs. This preliminary setup ensures that when the pipe is installed, it automatically assumes the correct position and orientation without requiring complex adjustment mechanisms.
2Reliability
If the fire extinguishing pipe is fixed rigidly to prevent detachment, then the reliability is improved, but the ease of operation deteriorates due to inability to adjust position
Solution Approach 1:
The system transitions from a static rigid fixation to a dynamic positioning mechanism. The anti-detachment members allow controlled movement during installation and maintenance while automatically securing the pipe in the correct position during normal operation. The heat detection member further dynamically adjusts the system state by triggering spray hole opening in response to temperature changes.
Solution Approach 2:
The guide rails act as intermediaries between the rack frame and the fire extinguishing pipe, providing a guided path that constrains the pipe to move only in the desired direction while maintaining proper orientation. This intermediary structure enables both positioning reliability and operational flexibility without requiring rigid direct fixation.
3Productivity
If the fire extinguishing pipe is positioned close to battery modules for effective fire suppression, then the fire suppression efficiency is improved, but the object-generated harmful factors worsen due to potential interference with battery modules
Solution Approach 1:
The fire suppression capability is concentrated locally at the spray holes positioned near the battery modules, while the pipe body itself is constrained by guide rails and anti-detachment members to prevent interference. This local quality approach allows effective fire suppression at the critical location without the entire pipe structure interfering with battery module operation.
Solution Approach 2:
The harmful potential of the fire extinguishing pipe is extracted and neutralized by separating the functional element (spray holes) from the structural element (pipe body). The spray holes are positioned close to battery modules for effective fire suppression, while the pipe body is constrained by guide rails and anti-detachment members to prevent interference with battery module operation.

AI summary
An energy storage system includes: a rack frame accommodating battery modules; a sub-frame secured to the rack frame and facing a battery module of the battery modules; a guide rail concavely formed on a surface of the sub-frame; a fire extinguishing pipe arranged within the guide rail and including a spray hole through which a fire extinguishing liquid is sprayable; a heat detection member configured to surround the fire extinguishing pipe and open or close the spray hole in conjunction with a temperature variation; and a first anti-detachment member arranged between the guide rail and the heat detection member to prevent the fire extinguishing pipe from being detached from the guide rail.
