Description

Dual fire hose

The present invention relates to a fire hose, and more particularly, to a fire hose capable of shortening the time from the water supply to the spraying by quickly securing the water transfer path of the curved or folded fire hose at the time of water supply, The present invention relates to a double fire hose which can protect the fire hose.

Generally, a fire hose is used to spray water for fire suppression. Before use, it should be hanged in rolls or folded several times inside the fire extinguisher box.

Here, the conventional fire hose hanger is composed of a plurality of fire hose hanger open to the body, as disclosed in the Japanese Patent No. 10-0666554, so that the fire hose is hanged and folded in the state of being folded a number of times.

When the fire extinguisher is generated, the fire hose hung on the plurality of fire hose hanger is completely opened without folding to the point where the fire is generated, and then the high pressure water is supplied to suppress the fire.

However, when a folded state occurs in any part of the opened fire hose, when the high pressure water is supplied, the fire suppressor holding the end of the fire hose due to the high pressure supplied is moved by the instantaneous expansion of the fire hose by the high pressure There is a risk that the fire suppressor is not completely folded without being folded, and then the water supply to the fire hose is started.

Accordingly, the fire hose, which is curled or folded many times in the roll, is quickly spread so as not to have a folded portion so as to quickly secure the internal water conveying path so that the supplied water can be rapidly injected to the topic generating point, It is time to develop the technology that can secure the safety of the person holding the fire hose of the fire hose.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made keeping in mind the above problems occurring in the prior art, and an object of the present invention is to provide a water hose having a water conveyance path for conveying water, And a second hose having a flow path. When a fire occurs, a curved or a plurality of folded fire hoses are unfolded so as not to be folded, so that the water transfer path space inside can be quickly secured, The first hose is protected by the gas filled between the first hose and the second hose and the second hose is protected by the double hose which can reduce the contact area with the ground and reduce the frictional force with the ground. The purpose is to provide a fire hose.

The position retaining straps 330 'interconnect and fix the inner retaining sheet 310' and the outer retaining sheet 320 'at a plurality of positions.

As the spacing between the inner holding sheets 310 'and the outer holding sheets 320' is maintained by the plurality of position holding ropes 330 ', the gap holding unit 300' Thereby maintaining the distance between the hose 100 and the second hose 200.

The gap maintaining part 300 'is inserted into the gas flow path 220 between the first hose 100 and the second hose 200 and positioned.

Meanwhile, the inner holding sheet 310 'and the outer holding sheet 320' of the gap holding part 300 'are fixed to the corresponding hose by the position fixing member 340'.

Here, the position fixing member 340 'is applied to the inner holding sheet 310' and the outer holding sheet 320 'using an adhesive and joined to the hoses 100 and 200.

First, an adhesive material as the position fixing member 340 'is applied to the inner holding sheet 310' of the prepared space holding part 300 'and then adhered to the outer surface of the first hose 100.

After the adhesive is applied to the outer holding sheet 320 ', the adhesive is adhered to the inner surface of the second hose 200 and then the first hose 100 and the second hose 200 are rolled, Production is completed.

4, the second hose main body 210 is fixed at fixed intervals along the outer circumference of the first hose main body 110 by the fixing member 400 to form a plurality of gas flow channels 220 do.

The fixing member 400 fixes the first hose main body 110 and the second hose main body 210 by sewing, adhesive, or heat fusion.

In an embodiment, each gas flow path 220 is formed parallel to the first hose body 110 or spirally formed along the outer periphery of the first hose body 110.

Of course, each gas flow passage 220 may be in the form of a plurality of partitioned pockets along the longitudinal direction of the first hose body 110, and each of the pockets communicates with another adjacent pocket through the communication hole.

As shown in FIG. 5, the gas hose 200 further includes a gas discharging unit 500 for discharging the gas filled in the gas channel 220 of the second hose 200 to the outside.

A plurality of gas discharge units 500 are formed along the second hose 200 to rapidly discharge the gas filled in the gas discharge channel 220.

Therefore, the gas can be discharged at the same time as the water supply is stopped after the gas is suppressed, and the gas can be quickly returned to the preparatory step for suppressing the gas which may occur next time.

The gas exhaust unit 500 includes a gas exhaust port 510 and a discharge cover 520, a discharge fixing member 530, and a removable member 540.

A plurality of gas outlets 510 are formed along the second hose 200 and are formed at regular intervals along the outer circumference of the second hose 200.

The discharge cover 520 is provided to cover the gas discharge port 510 and the discharge fixing member 530 is provided to fix one end of the discharge cover 520 to the second hose 200.

The attaching / detaching member 540 is provided for opening / closing the gas outlet 510 by attaching / detaching the other end of the discharge cover 520 fixed by the discharge fixing member 530 to the second hose 200.

In this case, the attaching / detaching member 540 may be formed of at least one or more than one of the first and second hoses 200.

6, the gas discharging unit 500 further includes an open holding unit 600. As shown in FIG.

The open holding part 600 maintains the open state of the discharge cover 520 so that the gas filled in the gas flow channel 220 can be discharged.

The open holding portion 600 is composed of an open holding piece 610 and a holding piece holding member 620.

One end of the open holding piece 610 is positioned in the discharge cover 520 and the other end is pressed in the direction of the water transfer path 120 by the corresponding portion of the first hose 100 to open the detachable member 540 .

The holding piece 620 is provided to fix one end of the open holding piece 610 to the discharge cover 520.

Here, the open holding piece 610 is constituted by the holding and fixing portion 612, the holding pressing portion 614 and the holding hinge 616.

The holding and fixing portion 612 is fixed to the discharge cover 520 by the holding piece fixing member 620 and the holding pressing portion 614 presses the corresponding portion of the first hose 100 so that the discharge cover 520 To maintain the open state.

The holding hinge 616 also connects the holding portion 614 to the holding portion 612 in a rotatable manner.

The gas discharge port 510 is opened to discharge the gas by separating the attaching / detaching member 540 by pulling the discharge cover 520 outward after the gas is extinguished, The folded holding portion 614 is rotated so as to be interposed between the discharge cover 520 and the second hose main body 210 to maintain the opened state of the gas discharge port 510 to quickly discharge the gas.
