AI Technical Summary

Technical Problem

Existing detection technologies are insufficient to accurately reproduce fire hazard scenarios on the exterior facades of high-rise buildings in the laboratory, especially high-temperature particle splashes, falling welding slag from hot work operations, overheating of electrical wires, and flame overflow from inside the building, resulting in a lack of scientific basis for fire hazard assessment.

Method used

Employing a high-temperature particle heating device, a catapult device, an exterior structure simulation system, a visible light thermal imager, a K-type armored thermocouple, a distributed thermocouple array, and a multi-point temperature tester, the catapult device accurately simulates the behavior of high-temperature particle splashing. Combined with the collaborative acquisition of temperature field distribution, internal temperature rise, and visual image data by multiple devices, it achieves accurate simulation of various fire hazard scenarios.

Benefits of technology

It has achieved accurate simulation and quantitative assessment of four typical fire hazard scenarios on the facade of high-rise buildings, providing scientific experimental support for the optimized design of fire protection systems, ensuring the consistency and repeatability of experimental parameters, and expanding the simulation capabilities of the device.

Abstract

This invention relates to the field of building fire safety detection technology, specifically to a simulation testing device and method for fire hazards on the facade of high-rise buildings. The device includes a high-temperature particle heating device, a projectile launcher, a facade structure simulation system, a visible light thermal imager, a K-type armored thermocouple, a distributed thermocouple array, and a multi-point temperature meter. The projectile launcher includes an adjustable spring device, a directional guide rail, and a laser velocimeter. The adjustable spring device uses a three-stage coaxial compression spring in conjunction with a threaded preload adjustment knob to achieve stepless control of the initial launch velocity, and the laser velocimeter monitors the launch velocity in real time. This invention accurately simulates the splashing behavior of high-temperature particles through the projectile launcher, and combines multi-device collaborative acquisition of multi-source data such as temperature field distribution, internal temperature rise, and visual images to reproduce four typical fire hazard scenarios, providing support for the optimized design of fire protection systems for the facades of high-rise buildings.
