Problem
Existing fire-fighting equipment for high-rise and super high-rise buildings faces challenges with limited extinguishing height, difficult motor-driven deployment, and high costs, as well as inaccurate fire source detection and unsuitable fire extinguishing methods for urban environments.
Innovation Solution
A control system for fire-fighting trucks incorporating a command control equipment, launch control apparatus, turret control apparatus, and photoelectric detection equipment with a white light zoom camera, infrared camera, laser rangefinder, and integrated processing unit for precise fire source detection and bomb trajectory calculation, enabling high-precision fire suppression with adjustable magnification and fusion of infrared and white light images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a fire fighting truck with lifting height of 101 meters is used, then the fire extinguishing height is improved, but the vehicle width becomes 8 meters and gross mass becomes 60.2 tons, making it difficult to deploy in narrow streets and built-up areas
Solution Approach 1:
The patent replaces the traditional mechanical lifting system with a pneumatic projectile launching system. Instead of physically extending a water cannon to great heights, the system launches projectiles containing fire suppressant chemicals or rescue equipment to the target location, achieving high-rise fire suppression without requiring a large, immobile truck structure
Solution Approach 2:
The system uses pneumatic power to launch projectiles to high-rise buildings. The pneumatic launching mechanism propels projectiles containing fire suppressant chemicals or rescue equipment to the target floor, enabling fire suppression at heights that would be impossible with traditional mechanical lifting systems while keeping the vehicle compact
2Reliability
If the existing fire extinguishing bomb with center booster is used, then the fire extinguishing capability is provided, but a large amount of high-explosive fragments are produced, making it unsuitable for urban environments with dense population
Solution Approach 1:
The patent extracts and removes the explosive booster component from the fire extinguishing projectile. Instead of using an explosive charge to deliver the fire suppressant, the system uses pneumatic pressure to propel the projectile and release its contents, eliminating the harmful high-explosive fragments while maintaining fire extinguishing capability
Solution Approach 2:
The patent converts the harmful explosive force into a beneficial pneumatic propulsion mechanism. The pneumatic system uses controlled gas expansion to accelerate the projectile, transforming what would be a dangerous explosive event into a safe, controllable delivery mechanism that eliminates fragment hazards while maintaining delivery effectiveness
3Adaptability or versatility
If cameras with fixed focus are used for target detection, then the detection device can be provided, but the view field selection number is few and infrared and white light images cannot be fused
Solution Approach 1:
The patent employs zoom lenses with adjustable focal lengths instead of fixed-focus cameras. The dynamic adjustment capability allows the system to change magnification ratios based on target distance and size, optimizing the view field for different detection scenarios. This dynamic optical system enables both wide-angle survey and close-up inspection without requiring multiple fixed cameras
Solution Approach 2:
The patent merges infrared and white light imaging capabilities into a single integrated detection system. By combining these different spectral modalities, the system achieves enhanced target detection capability that works in various lighting conditions, including complete darkness, while the image fusion technology integrates the data from both sensors into a unified view
