Example one

Referring to fig. 1, the embodiment discloses a quick extinguishing device of single-ended tunnel in pit, including power 1, high bubble fire extinguisher 2, dryer 3, enclosure wall 4, scene of a fire 5.

Referring to fig. 1, a power source 1 is connected to a high-bubble fire extinguisher 2 through a power cord.

Referring to fig. 2, the upper end of the high-foam fire extinguisher 2 is fixedly connected with a valve 21, and the lower end of the high-foam fire extinguisher 2 is fixedly connected with a water pipe variable head 6.

In this embodiment, the high-foam fire extinguisher 2 uses high-expansion foam fire extinguishing agent with a foaming rate of 201-.

In the embodiment, the high-foam fire extinguisher 2 continuously generates a large amount of air mechanical foam to quickly fill the limited underground roadway space, and forms a foam plug to push the foam plug to the fire source, so that the effect of covering a burning object and stopping air supply is achieved, the large amount of foam can surround the fire source and prevent heat conduction and convection level radiation, the expansion and spread of the fire source are blocked, and the effect of sealing the fire source is effectively achieved.

In this embodiment, water pipe becomes head 6 and can select according to the underground pipe coupling, and the problem of the accessory complicacy of high bubble fire extinguisher 2 has effectually been solved.

Referring to fig. 1, one end of the high-foam fire extinguisher 2 far away from the power supply 1 is fixedly connected with an air duct 3, and the air duct 3 is made of a flame-retardant material.

In this embodiment, high bubble fire extinguisher 2 can change the diameter size according to actual demand, and the most preferred is 800mm, 600mm and 400mm, and 600 mm's dryer wind send the effect of putting out a fire the foam relatively better, and 400mm dryer is applied to apart from the fire control effect in longer space better.

Referring to fig. 1, the closed wall 4 is built at the front end of a fire scene 5, the closed wall 4 is built by a plate wall or a brick wall, the area of the cross section of the closed wall is 15 square meters, the lower end of the closed wall 4 is provided with a reserved opening 41 matched with the diameter size of the wind tube 3, and the whole space is effectively filled with fire extinguishing foam quickly and effectively, so that a fire suffocation area is isolated to the maximum extent, and the fire extinguishing speed is effectively improved.

The working principle of the embodiment is as follows: the staff builds enclosure wall 4 at the front end of scene of a fire 5, and set up reservation mouth 41 in its lower end, be connected the one end of dryer 3 with high bubble fire extinguisher 2, the other end embolias the inside of reserving mouth 41, each parts are connected and are accomplished the back, one person starts the power supply, one person stirs high multiple foam and puts out a fire the medicament in order to ensure that the medicine is normal, one person reserves the fork at the enclosure wall and guards the fork and connect and the medicament is full of the condition of spilling over, treat that the foam of putting out a fire is full of enclosure space and leaves the back from enclosure wall crack, last medicine supply a period can stop the operation of putting out a fire, the utility model discloses for traditional fire extinguishing method, this fire extinguishing system is light, easily transports, easily operates, puts out a fire the security simultaneously strong, fast, efficient, and the cost of putting out a fire is extremely low, little to the influence of system after putting out a fire, can furthest guarantee mine normal production.

Example two

Referring to fig. 2, the difference between the second embodiment and the first embodiment is that the water pipe in the fire place in the well is not supplied with water normally, and the water pump 7 is connected to the end of the water pipe tap 6 away from the valve 21.
