The first nozzle seat 16a is positioned at an angle of 38 ° preferably 33 to 43 ° with respect to the center line C of the nozzle head 10, and the second nozzle seat 16b is It is preferable to position it at an angle of 75 to 85 degrees, preferably 78 degrees, with respect to the nozzle head center line C. For example, the angle of the first nozzle seat 16a is also less than 33 degrees or more than 43 degrees. If large, the angle of the extinguishing material discharged to the flame at the fire site is too small to affect the discharge of the extinguishing material discharged from the central direct discharge port 18 of the nozzle head 10 or to be discharged too obliquely to reduce the fire suppression effect. Because.

In addition, when the angle of the second nozzle seat 16b is smaller than 75 ° or larger than 85 °, the extinguishing material injected through the first and second nozzle seats 16a and 16b overlaps or is discharged at a right angle. This makes it easy to block the fire and firefighters, but it does not help to extinguish the flame at all.

Therefore, the angle of the first and second seating holes 16a and 16b in the nozzle head 10 of the present invention will be most preferable.

On the other hand, the nozzle 12 mounted to the nozzle seat 16 may be installed to be able to adjust the spray angle individually by rotating itself, for example, as shown in Figure 12, in the center A nozzle support 12b for inserting and fixing a spherical nozzle 12 having an injection hole 12a into a nozzle seating hole 16 formed in the nozzle head 10 to make the contact surface of the nozzle spherical to enable nozzle rotation. Can be assembled to enable individual angle adjustment of the nozzle 12.

At this time, although schematically shown in the drawing, the nozzle support 12b forms an inner circumferential surface into a spherical surface and disassembles and assembles through a bolt or the like to enable internal assembly of the nozzle 12.

Next, as shown in Figure 1b and 2b, the present invention fire fighting apparatus 1 can be used with other fire fighting equipment, for example, the rush pipe 130, the center of the nozzle head (10) The screw portion S may be formed at the direct discharge port 18, and the rush tube 130 may be fastened to the screw portion S.

Therefore, in this case, the fire fighting apparatus 1 of the present invention can simultaneously use a linkage mechanism such as the dash tube 130 while discharging the extinguishing material for extinguishing the fire in a desired discharge form (injection or direct weaving, or a combination thereof). It is possible to easily adjust the discharge form through the operation of the discharge variable rotation body 70, while performing the fire suppression more effectively, so that the structure of the fire-fighting device is simple, maintenance and easy to reduce the cost, such as manufacturing It is possible.

As described above, according to the present invention, the fire fighting apparatus, firstly, at any place, such as a fire scene, by discharging extinguishing materials such as extinguishing water, extinguishing foam, or extinguishing liquid in various forms and directions through a simple operation through a lever. In addition, the amount of discharge can be adjusted to provide an advantage that makes it possible to extinguish the fire more effectively according to the type of fire.

Second, if necessary, it is possible to use a linkage mechanism such as a rush pipe, so that it is easier to extinguish the fire, and in addition, it is possible to individually adjust the spray direction of the spray nozzles to maximize the fire suppression pressure.

Finally, it is manufactured in a simple structure that does not require a separate valve while simply assembling and disassembling in a screw form, making it easy to manufacture, and in terms of cost that reduces the manufacturing and maintenance costs by facilitating maintenance and maintenance of the device. It is to provide a low cost excellent effect.
