Embodiment Construction

[0022] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0023] Before introducing the present invention, first introduce the principle of the compressed air foam system, figure 1 is a block diagram of the compressed air foam system provided by the present invention, such as figure 1 As shown, the compressed air foam system is powered by the vehicle power components (including the engine), and the corresponding flow and pressure of air, water and foam liquid are respectively obtained through the air balance component, water supply component and foam proportional mixing component. Among them, the power component is used to provide power for the compressed air foam system, the air balance component is used to provide t...

Abstract

The invention discloses a vehicle-mounted compressed air foam system and a vehicle with the same. The system acquires power through a vehicle power assembly, and acquires air of corresponding flow and pressure, water and foam liquid through an air balance component, a water supply component and a foam proportionally mixing component. An air compressor air inlet valve in the air balance component is communicated with a vent hole disposed on a vehicle exhaust pipe, so that air passing through the exhaust pipe enters the air compressor. By opening the vent hole on the vehicle exhaust pipe, the compressed gas of foam for fire extinguishment is made from gas passing through the exhaust pipe, so that the content of air in the foam for fire extinguishment can be effectively reduced, and then the fire extinguishing efficiency is greatly improved.

Description

technical field [0001] The present invention relates to the technology of producing compressed gas for fire extinguishing, in particular, to a vehicle-mounted compressed air foam system and a vehicle with the system. Background technique [0002] In the event of a fire, the most commonly used extinguishing agents are water, foam and carbon dioxide. The method of foam fire extinguishing is to mix and foam air, water and foaming agent under specific pressure and ratio conditions to produce a specific fire extinguishing foam. Compared with direct water extinguishing, foam can improve the original physical properties of water, and has the effect of heat absorption and isolation, enhances the ability to penetrate into the interior of the burning material and adhere to the surface of the burning material, and also has the ability to reduce the surface tension of water and increase the energy of water. Therefore, using foam to extinguish fire can quickly and effectively prevent th...
