Fire extinguishing efficiency detection method and system of wind-driven wildland fire fighting equipment

Abstract

The invention discloses a method for detecting the fire extinguishing efficiency of wild fire-fighting equipment dominated by wind force, which includes: planting herbaceous plants with stable and orderly physical and chemical properties on a rectangular fuel bed according to the set water content, distribution density and height; One end is ignited from the root of the herbaceous plant by a linear igniter, forming a local fire situation on the field surface that spreads to the other end; when the burning flame is fully developed and begins to spread stably to the test section, start the fire extinguisher, and the heat flow meter group measures the effect of the fire extinguisher After the flame spreads in the fuel bed, set the observation point to accept the change of the radiation heat flux intensity; measure and determine the fire extinguishing efficiency of the fire extinguishing equipment in a specific working state according to the change and the derived calculation parameters and algorithms. The method of the present invention arranges herbaceous plants in accordance with the distribution of combustibles on the surface on the standard fuel bed, adds an inclination adjustment mechanism, side heat insulation and anti-natural entrainment baffles, and simulates the natural convection mechanism of wild fires to create a typical fire. The scene of the dynamic spread of localized surface fires.

Description

Technical field [0001] The present invention relates to quantization evaluation techniques for fire extinguishing performance of field fire extinguishing machines, especially for portable wind fire extinguishing machines and quantitative calibration of fire-fighting equipment efficiency, which is dominated and superimposed in auxiliary fire extinguishing function, providing a wind-leading field fire rescue Method and system for improving equipment. Background technique [0002] With wind-led field fire on-site, the equipment is extremely widely used in my country's forest fire industry. Such devices have high portability and can be used in a remote region of traffic inconvenience. Especially for geographicals that are far from the water source, they have become a crucial operation tool for the first-line rescue team. Long-term practice shows that a wind fire extinguisher has argued that 20-30 pavilors adopt an easy "No. 2 tool" to the fire line. According to preliminary estimates...

Problems solved by technology

However, wood stack fires are mostly used for fire simulation tests inside buildings, which are not typical for fire scenes that spread dynamically in the wild.

More importantly, due to the lack of reliable detection parameter extraction and analysis and corresponding quantitative evaluation indicators, the relevant tests are of demonstration nature
