Fire truck and fire protection foam system thereof

Abstract

The invention discloses a fire protection foam system for a fire truck. The fire protection foam system comprises a water pot and a foam liquid pot which are used for storing fire protection media, a water pump and a foam pump which are used for pumping the fire protection media, a fire nozzle for outputting the fire protection media, a foam uniformly mixing tube and an air compressor, wherein the outlet of the foam uniformly mixing tube is communicated with the inlet of the fire nozzle, and the inlet of the foam uniformly mixing tube is respectively communicated with the liquid outlet of thewater pump and the liquid outlet of the foam pump; and the compressed air outlet of the air compressor is communicated with the inlet of the foam uniformly mixing tube. The fire protection foam system for the fire truck is provided with compressed air supply equipment; when the fire protection foam system is used, the compressed air and mixed liquid of water and foams firstly enter the foam uniformly mixing tube and are pre-foamed and then jetted by the fire protection fire nozzle with low water consumption. On the basis of the fire protection foam system, the invention also provides the firetruck, which comprises a chassis, a lifting arm frame, a working platform and the fire protection foam system for the fire truck; and the working platform is connected with the chassis through the lifting arm frame.

Description

technical field [0001] The invention relates to fire-fighting equipment, in particular to a fire-fighting vehicle and its fire-fighting foam system. Background technique [0002] Fire fighting, emergency rescue and disaster relief operations play a very important role in ensuring the safety of people's lives. The important task of fire fighting work is to use various advanced fire fighting technology and equipment to scientifically deal with frequent fires and various emergencies, and to control the spread of the situation. , to reduce the loss caused by the event. As a special vehicle used in special circumstances, fire trucks play a very important role in social and economic activities; for example, fire trucks for climbing platforms. [0003] Existing fire trucks for climbing platforms are widely used in fire-fighting operations, and are especially suitable for handling disasters and accidents with greater uncertainty and randomness. The climbing platform fire truck has...

AI Technical Summary

Problems solved by technology

However, the water content of the fire-fighting foam sprayed by the existing fire-fighting foam system is relatively high, and a large amount of water is used when extinguishing the fire, which will cause people in the ruins to drown and cannot breathe or die; human principle

[0004] In addition, due to the high tension on the surface of water molecules, poor permeability, and low reburning resistance; in addition, the water itself has good fluidity, and the heat taken away by the short residence time on the surface of combustible solids is relatively small, so it will inevitably lead to higher large water consumption

Therefore, the existing climbing platform fire trucks cannot be used in water-deficient areas, especially economically underdeveloped areas with outdated and backward fire-fighting pipe networks
