High-pressure spraying fire-extinguishing device directly driven by engine and capable of automatically mixing fire extinguishing agent

Abstract

The invention discloses a high-pressure spraying fire-extinguishing device directly driven by an engine and capable of automatically mixing a fire extinguishing agent. A fire extinguishing agent stock solution and water are separately stored by virtue of a water tank and a fire extinguishing agent stock solution tank which are independently arranged; compared with a current scheme of pre-mixing the fire extinguishing agent with water, the high-pressure spraying fire-extinguishing device prolongs effective life of the fire extinguishing agent; when fire extinguishing is required, the fire extinguishing agent stock solution and the water can be automatically added and mixed, so that the fire extinguishing efficiency is improved; and a filling loop of the fire extinguishing agent stock solution can be independently controlled to switch on and switch off, so that the fire extinguishing agent stock solution is not lost and only a little water is lost while a function test spray try is carried out at a fixed period, and therefore, supplementing cost is low.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment, in particular to a high-pressure spray fire-extinguishing device directly driven by an engine, which can realize the automatic addition and mixing of fire-extinguishing agent stock solution. Background technique [0002] Existing fire-fighting equipment generally has a valid period of use, and fire-fighting facilities that have passed the period of validity generally cannot be used, resulting in waste. For liquid fire extinguishing devices, even if the fire extinguishing agent has not expired, its internal pressure will decrease with the increase of storage time. Partly, when the fire extinguishing area is large, the fire extinguishing equipment with a small number of spares cannot effectively extinguish the fire. [0003] At present, in the pump group type fire extinguishing agent type fire safety protection system, water and fire extinguishing agent are premixed for storage, bu...

AI Technical Summary

Problems solved by technology

[0004] First of all, after the fire extinguishing agent stock solution is mixed with water, its shelf life is significantly shorter than that of the fire extinguishing agent stock solution, so it cannot be stored for a long time

[0005] Secondly, due to the pre-mixed storage of the fire extinguishing agent stock solution and water, the fire extinguishing agent mixture will be lost during the regular functional test spraying. Increase
