Automatic Security Bottle System for Confined Space Fire Suppression
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic fire extinguishing systems face challenges in inaccessible spaces, require complex installations, and are not effective in small, confined areas like battery compartments of new energy vehicles, with issues such as one-time use, difficulty in refilling, and ineffective detection before fires occur, leading to potential safety hazards and equipment damage.
Innovation Solution
An automatic security bottle system with a bottle valve mechanism that includes a piston to control the release of extinguishing medium based on pressure changes, utilizing wired or wireless signal transmission for control and detection, allowing for multiple releases and adaptable volume control, and incorporating electromagnetic and manual actuation for automatic and remote operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional fire extinguishing systems are used in narrow or inaccessible spaces, then fire extinguishing function is provided, but the system complexity and installation difficulty increase significantly
Solution Approach 1:
The system divides the fire protection function into independent security bottles, each capable of autonomous operation. Each bottle contains its own control system, detector, and extinguishing medium, allowing modular deployment in narrow or inaccessible spaces without requiring complex centralized piping and wiring.
Solution Approach 2:
The security bottles are designed with automatic detection and release mechanisms that operate autonomously without external control. The bottles self-monitor their status, automatically release extinguishing agent when fire is detected, and can be remotely refilled without manual intervention in hazardous areas.
2Reliability
If conventional fire extinguishing systems are used, then fire extinguishing is achieved, but maintenance and refilling require personnel access to protected areas
Solution Approach 1:
The system incorporates remote refill capability where extinguishing agent can be replenished through external ports without personnel entering protected areas. The bottles include status monitoring and automatic detection systems that notify operators of refill needs, enabling maintenance from safe distances.
3Reliability
If one-time use fire extinguishing systems are deployed, then initial fire protection is provided, but repeated releases require system replacement
Solution Approach 1:
The security bottles are designed for multiple release cycles with refillable extinguishing agent reservoirs. After discharge, the system automatically or manually refills the bottles, maintaining continuous fire protection capability without requiring replacement of the entire system, thus enabling repeated releases in the same protected area.
4Reliability
If early fire detection is implemented, then fire safety is improved, but detection before fire occurrence remains challenging
Solution Approach 1:
The system incorporates multiple detection technologies including smoke, heat, and gas sensors that monitor for early signs of fire development. The controllers analyze sensor data to detect abnormal patterns indicating incipient fire conditions before actual combustion occurs, enabling preventive action.
5Reliability
If existing fire extinguishing systems are used in battery compartments, then some protection is provided, but effective fire suppression in confined spaces is difficult
Solution Approach 1:
The system uses compact security bottles specifically sized for confined spaces like battery compartments. Each bottle is a self-contained unit that can be strategically positioned within limited volume, delivering concentrated extinguishing agent directly to fire hazards without requiring large storage volumes or complex distribution systems.
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 system provides reliable, multiple-stage fire prevention and extinguishing, detecting potential hazards early and releasing extinguishing agents before fires occur, ensuring safety in confined spaces and minimizing damage through controlled medium release.
Implementation Method 1
the piston 6-2 can move up and down when the gaseous pressure in the upper cavity 6-3 and/or the lower cavity 6-4 changes, so as to open or close the valve port 6-7
Implementation Method 2
the gas in the upper cavity 6-3 discharges outward, the pressure of the upper cavity 6-3 reduces, and the piston 6-2 moves upward, thus realizing the automatic opening of the valve port 6-7
Implementation Method 3
the electromagnetic actuator 15 drives the thimble to move up and down, so as to open or close the check valve
