Adaptation and advantages of fire hoses in unmanned aerial vehicle firefighting
In the unmanned aerial vehicle fire protection system, the water hose is a key component that connects ground water supply and aerial firefighting. It not only needs to ensure the stability of high-pressure water supply, but also has lightweight and durability to meet the special needs of drone flight. With the development of firefighting technology, specialized UAVs for attaching firefighting hoses have gradually become a focus of market attention.
Q1: What are the differences between drone fire hoses and traditional hoses?
Traditional water hoses are mainly used for ground operations and are made of heavy materials. Although they have strong pressure resistance, they are not conducive to aircraft suspension. The drone fire hose adopts lightweight polymer composite materials, which reduces the weight by about 30-40% compared to traditional hoses, greatly reducing the load pressure of the drone.
In addition, the surface of the dedicated water hose has undergone anti friction treatment to reduce wear and tear when in contact with building exterior walls or trees; Internally, a polymer fiber reinforcement layer is used to ensure pressure resistance (able to withstand high pressures of 8-12 bar) without affecting flexibility. These designs make it more suitable for long-term suspension and complex environmental operations.
Q2: What are the requirements for the performance of water hoses in high-pressure water supply?
Drone firefighting often requires high pressure and continuous water supply, which places higher demands on the water hose:
Pressure resistance and stability: it must maintain no leakage or bursting under high pressure for a long time.
High temperature resistance and flame retardancy: In the high temperature environment of the fire scene, the water hose needs to have a flame retardant coating to avoid damage from external flames.
Anti torsion and anti bending: During the suspension process, the water strip is easily affected by wind and gravity, and good anti torsion can avoid water supply interruption.
Quick connection: The hose interface needs to be compatible with multiple ground pumping stations to ensure quick connection to different countries and fire protection systems. These characteristics make the drone fire hose not just an accessory, but one of the core components that determine fire extinguishing efficiency and stability.
The drone specific fire hose has significant advantages in lightweight, pressure resistance, flame retardancy, etc., and is a key link to ensure the efficient operation of drone fire protection systems. With the growth of market demand, this specialized hose will gradually replace general-purpose products and become an indispensable standard configuration for drone firefighting in the future.
