Description

[Detailed Description of the Invention] The present invention relates to a backpack-type fire extinguishing device used for extinguishing embers such as forest fires.

That is, in a fire extinguishing system configured such that a fire extinguishing liquid bag connected to a manual pump having a nozzle at the tip can be carried on the back using a backpack strap, this type of fire extinguishing system is light and can be used accurately and quickly. The drawback is that the manual pump is extremely tiring to operate back and forth, and
The drawback was that if the fire extinguishing area was wide, effective fire extinguishing operations could not be carried out.

The present invention is an improvement based on the drawbacks of the above, and when such fire extinguishing work is required, a power unit can be easily attached to the fire extinguishing system to make it a power type, and it can be used in accordance with the extinguishing state. To provide a fire extinguishing system that enables accurate, quick and effective fire extinguishing work, and has a simple structure so that it can be carried out suitably.

Next, the embodiment shown in the drawings will be described.

2 is a fire extinguishing liquid bag, a cap 8 is installed at the supply port on the upper side, and an end of a flexible hose 10 is connected to the connector 1 to a discharge pipe 9 that projects rearward on the lower side.
A manual pump 1 is constructed of a piston part 1a and a cylinder part 1b, which are detachably connected to each other through a flexible hose 10 and have a nozzle 12 at the tip thereof on the extending side of a flexible hose 10.
are configured by connecting them in series.

Further, two shoulder straps 3, 3 are connected to the fire extinguishing fluid bag 2, and both backpack straps 3, 3 are half-side having a plurality of locking holes 13 from the top of the fire extinguishing fluid bag 2 to the tip side. A long strip 3a is extended, and a short half strip 3b is extended from the bottom of the fire extinguishing solution bag 2, and the short strip 3b has a connecting fitting 14 on the tip side that can be locked in the locking hole 13. do.

In FIGS. 2 and 3, 7 indicates the entire support frame, and the support frame 7 is formed by bending one rod so that the entire side surface is L-shaped.
The horizontal rod 7a at the upper end of the front upright part is equipped with locking parts 15, 15 having insertion holes 15a through which the strips 3a, 3a can be inserted. A support rod 16 on which the strips 3b, 3b can be engaged is installed horizontally, and an engine stand 17 is installed on the end of the rear horizontal portion of the support frame 7.

Furthermore, a small engine 6 is installed above the engine stand 17 in the support frame 7;
A pump section 5 driven by the engine 6 is installed on the side of the engine 6, and a suction pipe 18 protruding from the pump section 5 and a discharge pipe 9 of the extinguishing liquid bag 2 are connected via a connector 11. The nozzle 4 equipped with an operating lever 20 is connected to the distal end side of a long flexible hose 19 which is installed so as to be detachably connected and extends from the pump part 5.

4 and 5 show another embodiment, which is indicated by the same reference numerals as the previous embodiment and has a substantially similar structure, but the upper end of the front upright portion of the support frame 7 has a horizontal rod projecting slightly forward. 7a and the support rod 21 on the inside thereof are installed in parallel, and short vertical rods 22, 22 are installed between the rods 7a, 21, and both sides surrounded by each rod 7a, 21, 22 are installed. The strips 3a, 3a are installed in both holes 23, 23 so as to be inserted therethrough.

Therefore, as shown in FIG. 1, a flexible hose 10 is connected to the discharge pipe 9, and the strip 3a and the strip 3
When carrying the extinguishing liquid bag 2 on one's back by wearing the double shoulder straps 3, 3 connected by the connecting fittings 14, the extinguishing liquid can be spouted from the nozzle 12 while operating the manual pump 1 with both hands. It will be possible to extinguish residual fires such as wildfires.

In addition, as shown in FIG. 2, the discharge pipe 9 and the suction pipe 18 on the side of the pump section 5 are connected by a connecting tool 11, and the fire extinguishing liquid bag 2 is aligned with the front upright part of the support frame 7, so that both belts are connected. A double backpack with pieces 3a and 3a inserted through the upper insertion holes 15a and 15a, respectively, and hooked onto the lower support rods 16 of both band pieces 3b and 3b, and the band pieces 3a and 3b connected by a connecting fitting 14. When you put bands 3 and 3 on both shoulders,
You can carry the whole thing on your back, holding the nozzle 4 side,
Fire extinguishing work can be performed by ejecting digestive fluid from the nozzle 4 in a distant direction using power.

The state shown in FIG. 4 is a state in which fire extinguishing work is carried out using a power system, similar to the embodiment shown in FIG. The lower part abuts against the support rod 16, and the entire body is suspended by the strips 3a, 3a inserted through both holes 23, 23, so that it can be carried on the back.

In the above embodiment, the backpack bands 3, 3 are connected to the support frame 7, but the fire extinguishing liquid bag 2 itself may be detachably attached to the support frame 7.

As described above, the present invention provides a fire extinguishing device in which a fire extinguishing fluid bag 2 connected to a manual pump 1 having a nozzle 12 at its tip can be carried on one's back using a shoulder strap 3, in which a fire extinguishing fluid bag 2 that protrudes from the fire extinguishing fluid bag 2 is provided. A flexible hose 1 which detachably connects the manual pump 1 to a discharge pipe 9 and has a nozzle 4 at its tip.
A support frame 7 is equipped with a pump section 5 communicating with the pump section 9 and an engine 6 that drives the pump section 5.
The fire extinguishing liquid bag 2 and the shoulder strap 3 are removably connected, and the discharge pipe 9 and the pump section 5 are removably connected, so that switching from manual to powered fire extinguishing is possible. With the backpack strap, you can carry the fire extinguishing solution bag on your back and operate the manual pump while extinguishing fires in the same way as before.In addition, by connecting the fire extinguishing solution bag to the support frame and carrying the whole thing on your back with the backpack strap, you can perform power-operated extinguishing operations. This means that fire extinguishing work can be carried out, and the fire extinguishing liquid bag and shoulder strap can be used in common and the configuration can be easily changed to manual or power type, and can be changed to manual or power type depending on the extinguishing situation. It has the advantage of being able to carry out effective fire extinguishing work accurately, quickly, and with a simple structure that can be carried out suitably.
