首次首辆！救援演习中这些硬核产品亮绝活

Core Points - The exercise named "Emergency Mission 2025" was conducted to test new rescue capabilities in extreme disaster scenarios, involving over 2,000 personnel and various aircraft [1][2] - The exercise included the introduction of advanced firefighting technologies, such as a high-temperature explosion-proof firefighting robot capable of operating at 1,000°C for over 30 minutes [4][5] - A new large-flow remote firefighting system, including the world's first liquid nitrogen foam firefighting vehicle, was showcased during the exercise [5][11] Group 1 - The exercise simulated a scenario where a large storage tank experienced an explosion due to extreme weather, leading to a fire that required immediate rescue efforts [6] - The large-flow remote trailer cannon used in the exercise can spray over 500 liters of extinguishing agent per second and has a range of 140 meters, making it the most powerful in the domestic hazardous chemical rescue field [8][10] - The liquid nitrogen foam produced by the new firefighting vehicle provides superior cooling and oxygen isolation, enhancing firefighting effectiveness by 2 to 3 times compared to conventional foam [13][14] Group 2 - The exercise aimed to validate the effectiveness of new materials, technologies, and tactics in emergency rescue operations, with a focus on real-world applicability [2][3] - The introduction of the high-temperature firefighting robot addresses the challenge of approaching fire scenes where temperatures can exceed 1,000°C, which is difficult for human firefighters even with protective gear [4][5] - The liquid nitrogen foam's ability to create a stable covering layer on burning surfaces helps in cooling and preventing oxygen from reaching the fire, thus enhancing overall firefighting capabilities [13][14]
