Solution Overview
Problem
Prior art robotized fire-fighting units are inefficient in determining ignition coordinates in a three-dimensional system and require significant water resources, complex infrastructure, and electric power, making them unsuitable for areas with limited water resources.
Innovation Solution
A robotized nitrogen-water fire-fighting complex with carriage-mounted barrels, nitrogen generator, and ejection devices that deliver small quantities of water in a nitrogen stream, eliminating the need for pumping stations and electric power substations, and using ambient nitrogen as an efficient fire-extinguishing medium.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If traditional water-based fire-fighting systems are used, then fire extinguishing capability is achieved, but water consumption is high and infrastructure complexity increases
Solution Approach 1:
The invention changes the physical state and delivery parameters of the fire-extinguishing agent by using compressed nitrogen gas to deliver water in a spray form rather than traditional liquid flow, reducing water consumption from liters to milliliters while maintaining extinguishing effectiveness
Solution Approach 2:
The invention applies pneumatic principles by using compressed nitrogen gas stored in cylinders to propel and spray water through ejection devices, replacing traditional hydraulic pumping systems and eliminating the need for water supply sources and electric power substations
2Quantity of substance
If nitrogen is used as the fire-extinguishing medium, then water requirements are reduced, but the system requires nitrogen storage infrastructure
Solution Approach 1:
The invention uses replaceable nitrogen cylinders that can be refilled or replaced when depleted, providing a simple and inexpensive storage solution compared to permanent infrastructure, aligning with the principle of using disposable or easily replaceable components
Solution Approach 2:
The nitrogen cylinders serve as self-contained pressure sources that automatically deliver the required gas pressure without external compression equipment, making the system self-sufficient and eliminating the need for external power or compression infrastructure
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
Significantly reduces water consumption, allows efficient fire extinguishing without capital-intensive infrastructure, and is suitable for areas with limited water resources, effectively directing fire-extinguishing agents to ignition sources.
Implementation Method 1
water is ejected in small quantities and delivered in spray form in the nitrogen stream
Implementation Method 2
water particles that have enough energy and a high initial velocity increase the jet range, and as they enter the high-temperature area they vaporize and absorb a significant quantity of heat
Implementation Method 3
nitrogen displaces oxygen from the ignition area, and as the specific oxygen content decreases below 10%, burning stops

AI summary
Achieved is a significant reduction in water requirements and use of an accessible alternative fire- extinguishing medium for which there is no need for a pumping station, a water supply source, and an electric power substation. This is achieved in a robotized nitrogen -water fire - fighting complex comprising two or more robotized fire - fighting units (1) mounted on a pipeline (2); a control panel (7), a control device (10) generating control instructions for barrel pointing and fire - fighting; an ignition detection and remote observation device (11) mounted on the barrels, being connected to a video signal processing device (17) determining the coordinates of the ignition sources, and connected to the video monitoring device (14) and the control device, the complex further comprising a nitrogen generator (23) connected to a receiver (22) containing nitrogen and connected to the pipeline for supplying nitrogen to the carriage -mounted barrels (3), and ejecting devices (24) supplying water into the nitrogen flow.
