A transparent window 61a is installed in the sub box 61 to protect the built-in general image camera 62 and the thermal image camera 63 from harsh fire environments.

The general video camera 62 photographs a fire scene as a general video and transmits the captured video signal to a display of a firefighter who directs firefighting work in a safe area.

The thermal imaging camera 63 photographs the same fire scene taken by the general video camera 62 and transmits the photographed video image signal to the commanding firefighter's display.

The commanding firefighter compares the fire scenes taken by the normal video camera 62 and the thermal imaging camera 63 with a normal video and a thermal video, determines the priority area in the fight against fire, and sees the fire when viewing the normal video. In the fire scene where the suppression seems to have been completed, it is possible to confirm whether or not an ignition source remains through the thermal image.

For example, in a normal video, the fire may be completely extinguished, but in some cases, the ignition source is hidden and not visible. It can be confirmed.

The cleaning nozzle 64 washes the contaminants buried in the window 61a by high-pressure injection of the washing water H supplied from the high-pressure washing water pump 65 to the window 61a, and the high pressure supplied from the air pump 66 By spraying air into the window 61a, the washing water on the window 61a is removed instantaneously, and thus, a clear general image can be taken while the fire fighting is in progress.

A lot of smoke or combustible material is blown off the fire site, and when the smoke or combustible material is buried in the window 61a, the window 61a becomes opaque and the general video camera 62 cannot shoot the general video. In this case, the cleaning nozzle 64 removes the contaminants buried in the window 61a by high-pressure injection of the washing water H, and accordingly, the window 61a can be kept clean.

Here, the reason why the wiper is not used to clean the window 61a is that the rubber forming the wiper is damaged by the high heat generated at the fire site.

The first solenoid valve 67 can selectively block the nozzle line (L) connected to the high pressure washing water pump (65) or the air pump (66), thereby selectively supplying washing water or high pressure air to the cleaning nozzle (64), Accordingly, the window 61a can be quickly washed or dried.

The rear side of the nozzle body 51 is connected to the fire hose S, and high-pressure fire-fighting water supplied through the fire hose S flows in.

The nozzle cap 52 forms a detachable structure to enable maintenance inside the nozzle body 51. The high-pressure fire-fighting water flowing into the nozzle body 51 passes through the injection hole 52a of the inner diameter smaller than the stepped space 51a and becomes more high-pressure and is sprayed in the form of direct water to a distance.

As shown in FIG. 6, the fine atomizing nozzle 53 is formed on the nozzle body 53a and the nozzle body 53a entering the injection hole 52a when advancing in the stepped space 51a, and the injection hole ( Conical tip 53b exposed to the tip of 52a), a plurality of fine atomizing nozzle holes 53c formed on the conical tip 53b to eject the atomized spray three-dimensionally, and formed on the rear side of the nozzle body 53a It includes an inlet hole (53d) in communication with the fine atomizing nozzle hole (53c).

With this structure, the firefighters flowing into the inflow hole 53d are moved through a flow path formed in the nozzle body 53a and then sprayed in a three-dimensional manner while forming a non-atomization form through the atomization nozzle hole 53c. This atomization is not strong because it is sprayed in three dimensions, but it is effective when a fire occurs in a large area, absorbs ambient heat as it evaporates rapidly, and vapors quickly extinguish the surrounding space to extinguish the fire.

As shown in FIG. 6, the bridge mover 54 connects the atomizing nozzle 53 and the driving magnet 55, and at the same time, the atomizing nozzle 53 is located at the rear side of the stepped space 51a. In this case, a space is provided so that the fire water flowing into the stepped space 51a moves to the injection port 52a. To this end, the bridge mover 54 is radially extending to the connecting rod 54a connected to the rear side of the atomizing nozzle 53 and to the connecting rod 54a to support the inner circumferential surface of the cylindrical driving magnet 55 And a bridge 54b.

Is transferred between the first position (L1) and the second position (L2). For example, in the state of FIG. 5, a magnetic field that repels the driving magnet 55 is formed in the second driving coil 57, and a magnetic field that attracts the driving magnet 55 is formed in the first driving coil 56. When doing, the driving magnet 55 moves to the first position (L1) side, and accordingly, the atomizing nozzle 53 protrudes from the injection hole 52a.

The stepped groove 58 is formed on the side of the entrance edge where the injection hole 52a is formed, so that the stepped wing 59 is worn when the fine spraying nozzle 53 is advanced, and accordingly the fine spraying nozzle 53 is further provided. At the same time as not to proceed abnormally, it is completely blocked between the injection hole 52a and the stepped space 51a. Accordingly, the fire water flowing into the stepped space 51a is sprayed through the inlet hole 54a on the rear side of the atomizing nozzle 53 into the atomizing nozzle hole 54c.

The composite injection nozzle unit 50, as shown in FIG. 5, when the atomizing nozzle 53 is located inside the stepped space 51a, the fire water flowing from the fire hose S is a bridge mover ( 54) After moving the space between and between the atomizing nozzle 53 and the inner circumferential surface of the stepped space 51a, it is sprayed to the far side in the form of direct water N through the injection hole 52a of the nozzle cap 52.

In addition, when power is applied to the first and second driving coils 56 and 57, the second driving coil 57 forms a magnetic field that repels the driving magnet 55 and the first driving coil 56 generates a driving magnet ( 55) to form a magnetic field that attracts. Then, the driving magnet 55, as shown in Figure 7, while moving from the second position (L2) to the first position (L1) side of the atomizing nozzle 53 protrudes from the injection port (52a), on the other hand As the stepped blade 59 on the rear side of the nozzle 53 is engaged with the stepped groove 58 on the inlet corner side where the injection hole 52a is formed, it is completely blocked between the injection hole 52a and the stepped space 51a. In this state, the firefighting water flowing into the stepped space 51a through the fire hose S is introduced into the inlet hole 23d and is sprayed three-dimensionally in a fine spray form through the fine spray nozzle hole 53c.

Meanwhile, an opposite power is applied to the first and second driving coils 56 and 57 to form a driving magnet 55 and a repulsive magnetic field in the first driving coil 56 and driven to the second driving coil 57 When the magnetic field to attract the magnet 55 is formed, while the above-described opposite action is made, the atomizing nozzle 53 moves to the rear side of the stepped space 51a and becomes the state shown in FIG. 5, and the firefighter in this state It is sprayed to the far side in a direct water form through the injection port 52a.

As described above, according to the present invention, the shooting unit 60 is installed in the box bracket 40 in which the multi-injection nozzle unit 50 is installed. Suppression can be carried out.

In addition, since the photographing unit 60 includes a general image camera 62 for photographing a general image of a fire scene and a thermal image camera 63 for photographing a thermal image of a scene photographed by the general image camera 72, Firefighters can compare the normal image and the thermal image on the display to make effective fire suppression and at the same time confirm whether the fire suppression is complete.

In addition, since the multi-injection nozzle unit 50 can spray in a direct water form to reach a firefighter far away or in a widespread unsprayed form, an effective suppression method can be selected according to the characteristics of the fire site.

The present invention has been described with reference to one embodiment shown in the drawings, but this is only exemplary, and those skilled in the art will understand that various modifications and other equivalent embodiments are possible therefrom.
