Abstract

The invention discloses a water base foam fire extinguishing device based on fire fighting water in a fire hydrant. The water base foam fire extinguishing device comprises a fire fighting pump provided with a foam proportion mixer, and a water inlet connector connected with the fire hydrant, wherein a water source control device is connected between the water inlet connector and the fire fighting pump; the water source control device comprises a water source storage tank which is connected with a water source water inlet pipe and a water source water outlet pipe; the water source storage tank is internally provided with a liquid level meter; and the liquid level meter is used for controlling a water inlet solenoid valve on the water source water inlet pipe to be switched on and off. According to the water base foam fire extinguishing device, the fire fighting water with unstable pressure and flow speed in the fire hydrant is changed into water with uniform pressure and flow speed by the water source storage tank by virtue of the water source control device, so that the stability of the pressure and flow speed of the output water of the fire fighting water is ensured and the working condition requirements on the water are met in a process of forming a foam mixed solution by the foam proportion mixer; and finally, a water base foam fire extinguishing liquid based on the fire fighting water in the fire hydrant is formed by the mixing of the fire fighting pump.

Description

technical field [0001] The invention relates to a fire extinguishing device, in particular to a water-based foam fire extinguishing device based on fire water in a fire hydrant. Background technique [0002] At present, due to human and environmental factors, fires occur frequently, especially the diversification of burning loads, fast burning speed, and rapid spread, resulting in large-scale fires, serious losses, and many unfavorable factors such as difficulty in extinguishing. For the existing main continuous fire extinguishing equipment are fire trucks and fire hydrants, fire trucks are often slow in rescue due to their large size, poor roads, and narrow roads, and fire trucks are expensive to build and maintain, and do not have mass popularization equipment. possibility. Fire hydrants have become an important fire extinguishing device due to their wide distribution and continuous water supply capacity at any time. Due to the high pressure and instability of the fire wa...
