Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water spray nozzle for fire fighting and a method of using the same.

The water spray nozzle for firefighting, which is well known in Japan, is a straight pipe-shaped type that is connected to the -mst hose and allows water to be sprayed from the other part. This nozzle light cannot be carried by one person, and it is difficult to use it in a fire extinguishing area, a narrow place, or a scaffolding or violent place*, and sometimes the water can be sprayed in a wide area. In some cases, the recoil from the start of the fire caused the firefighter to fall down, which was a major obstacle to stable and efficient firefighting work. As a result of intensive research, we have completed the invention of a water spray nozzle for firefighting (hereinafter referred to as "water spray nozzle") that can reduce the reaction of water spray and efficiently carry out fire extinguishing operations, and an invention related to its method of use. I'll come.

In other words, one of the points of non-invention is to reduce the reaction of water spraying pressure at the beginning of water spraying, which is the biggest problem in firefighting operations, and to make firefighting operations MV--able to be carried out by humans. Water spray nozzle [Separated into a horizontal nozzle pipe section and a folding nozzle pipe section, when water is sprayed from the tip of the horizontal nozzle pipe section, the water is collected by the folding nozzle tube section, reduced in size, and given to the human body''** *Provide a water spray nozzle that reduces the amount of water sprayed above during Fi1/, c# 0-ml K kA 1m
iii Attach a handle to E, move the CO handle and place it on the ground, then hold it manually or unattended, or -
This provides a method for using a water nozzle that can be used to extinguish a fire manually.

The structure of the water discharge nozzle of the present invention and its usage will be explained below with reference to the drawings. This is a perspective view of an embodiment of a water discharge nozzle.

The handle 17jk is attached to the horizontal nozzle pipe in order to press it against the pipe crest and fix the handle 17jkIn.

In this way, the water discharge nozzle of the present invention has a 1 mm horizontal nozzle pipe (11

The nozzle pipe (2) is formed, and the force f) due to the reaction (reaction) K of the water pressure is broken down in the nozzle part (2). I don't fit into a meeting
A water discharge nozzle in which a horizontal nozzle pipe (1) and a prayer nozzle pipe (2) are integrally formed is also effective.

The water discharge nozzle of the present invention has been explained above.

Make sure that 7) does not move ◎ At this time, the tip of the water nozzle (2) - the injection port (4th sister, above ground - is facing upwards with respect to 〇) Therefore, the tip of the handle (7) (?) By attaching it to the ground WJ wheel, the water nozzle can be placed in a stable position and water can be sprayed almost unattended.

In addition, Figure 5 shows the back view of the second female, and the tip 11 (?)
It is structured so that it is stable (2 round bars (2

After turning the handle (7) downward, remove the bolt.
Holding a steady position, use your right hand to hold the nozzle (4t1) and the elbow (1m) to your left hand, and use the handle (7) and fold the nozzle tube to plow IJ11 to the side.
An example of how to use the holding method [as shown, -
Practical tests have proven that it is possible to easily extinguish fires by suppressing the BLIIJvt water spray using human power.

Figure 5 shows the tip of the handle (7) (71/l) with the left hand holding the water nozzle firmly, the right hand holding the water nozzle, and the injection port (4) of the handle (4).
This is a good example of how to use a hand-held nozzle.

As described above, there are many ways to use the water spray nozzle of the present invention.The handle (7) can be rotated and held on the ground depending on the situation at the fire extinguishing place. There are many options, such as hand-held or self-portrait, and it is also possible to centrally use one fire nozzle while wearing it unattended.

As described above, the present @O water spray nozzle and its method of use have excellent effects as described below.

■ Bending part of the water nozzle to release water
(Because we keep the number of
It can also easily extinguish fires in high-rise buildings and small dangerous spaces.

■ Since the structure is simple, it is easy to manufacture, inexpensive, and can be produced without failure, making it widely used.

■Unmanned fire extinguishing system 1i can be used, and the cost of extinguishing fires can be significantly reduced.
