The present invention relates to a mobile fire extinguishing device, so that the mobile fire extinguishing agent to store the foaming agent and the extinguishing water (water) in the form of a tube, and if necessary, spray the mixed solution using a pump, and where electricity cannot be used, one side The present invention relates to a mobile fire extinguishing device for a mixture of a spray agent and a water spraying agent that is capable of initially extinguishing a fire by discharging and mixing a foaming agent (foaming agent) and extinguishing water (water) by a compressed air tank.

In the past, mobile fire extinguishing devices have been provided in various forms. Looking at these conventional mobile fire extinguishers, powder fire extinguishers, gas fire extinguishers, etc., formed of small compression tanks are used in every home or office, and in industrial sites, a fire extinguisher with a larger capacity than a fire extinguisher provided in a home can be installed and moved. To help you.

As another fire extinguisher used in industrial sites, a fire extinguisher is installed inside a cabinet type case to be installed and used in an element of a fire zone, but there is a problem that such a fire extinguishing device cannot quickly extinguish a fire at an early stage. .

Looking at the prior art in this field, the mobile diluted spraying device (hereinafter referred to as "the prior art") of the registered patent publication No. 10-1584047 (registration date 01/05/2016) is driven to generate rotational force. An engine unit; A spray pump unit receiving a rotational force from the driving engine unit and pumping water stored in a water tank to discharge a high pressure through a drain pipe; And a mixing unit for mixing and discharging the water discharged from the spray pump and the saturation solution stored in the chemical tank, and the mixing unit is a straight pipe-type tube communicating with the drain pipe of the spray pump unit, and a bypass distribution port is formed in the inlet section. And the discharge section, each of which is a bypass pipe formed with a bypass recovery port; A bypass pipe, which is a bent pipe in which the inlet communicates with the bypass distribution port of the intuition and the outlet communicates with the bypass recovery port of the intuition, and the bypass pipe through which some of the water flowing into the intuition distributes and bypasses the defoaming solution stored in the chemical tank Disclosed is a configuration in which an injector for mixing with water moving along a bypass tube is disposed.

The above-described prior art is also a foam fire extinguishing agent mixed spray device for spraying water stored in a water tank and a foam fire extinguishing solution diluted with a foam extinguishing solution stored in a medicine container. It can be seen that such a prior art is an engine driving method using oil, so that a person can carry it using suspenders.

The prior art has the advantage that it can move freely and be used freely in areas where there is no electricity, but there is a problem that digestion is not smoothly performed due to the extremely limited amount of water stored in the water tank and the digestive fluid stored in the medicine container. have.
