BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguisher for extinguishing a fire in the event of a fire.

[0002]

2. Description of the Related Art In a water cannon as a fire extinguishing system for performing a fire extinguishing operation in the event of a fire, the water discharged from the water cannon is:
FIG. 14A showing the water discharge situation from above and FIG. 14 showing from the side
In general, as shown in B, the spread in the water discharge direction is easy, but the spread in the lateral direction is small. (Especially, in the case of long distance water discharge, it is necessary to reduce the horizontal spread because it is necessary to gather the water flow to fly the water as far as possible.) In this way, it is easy to spread in the water discharge direction, Even if there is some error in the distance in the water discharge direction to the fire point, the fire can be effectively extinguished if the tip stays at the fire point, but if it is shifted from the fire point in the horizontal direction, that is, in the turning direction of the water discharge gun, In some cases, even a small distance error cannot extinguish the fire. Thus, the shift in the lateral or turning direction is important, and the longer the distance from the water cannon to the fire point, the greater the effect of the shift. Therefore, in the case of fire extinguishing by an automatic water discharge gun that automatically detects a fire point, that is, a fire place, and discharges water, the shift in the lateral direction, that is, the turning direction, is a very important problem.

[0003] Therefore, it is necessary to test the direction of water discharge from the nozzle of such a water discharge cannon. Conventionally, such a test involves actually discharging water or visually observing the front from the rear of the nozzle. Or a TV camera is mounted above the nozzle of the water cannon and the scene in front of the nozzle is observed by the TV camera.

[0004] When water is actually discharged, there is a problem of water damage, and such a test method cannot be performed in a place where water cannot be actually discharged due to damage to equipment or the like. . In addition, there is a problem such as cleaning up of the discharged water, and there is a problem that it cannot be easily implemented. The method using visual observation or a TV camera from the rear of the nozzle has a problem that an error in the actual water discharge direction of the nozzle is so large that an accurate test cannot be performed.

[0005]

As a solution to the above problems, the applicant of the present invention attaches a laser beam transmitting means for transmitting a laser beam in a water discharge direction of a water cannon or a direction parallel thereto to the water cannon. First applied for a test device for a television-camera linked water cannon fire extinguishing system that can perform a high-accuracy test without actually discharging water by checking the place or position where light hits with a TV camera etc. doing. The present invention provides a water cannon fire extinguisher equipped with such a laser beam transmitting means.

[0006]

According to the present invention, therefore, according to the present invention, the water cannon is swiveled laterally by the rotation of a water cannon rotating part rotatably mounted on the water cannon main body, and the water cannon is rotated. In a water cannon fire extinguishing system that discharges fire-fighting water from a nozzle that is raised and lowered by a nozzle mounting part that is rotatable vertically in a vertical direction, including the direction of water discharge during testing To generate visible light at
A water cannon fire extinguisher characterized by being provided with visible light transmitting means is provided.

The visible light transmitting means may be mounted on the nozzle in parallel with the axial direction of the nozzle, may be mounted on the nozzle mounting portion in parallel with the axial direction of the nozzle, The water cannon may be attached to the water cannon rotation part in a plane including both the rotation axis of the water cannon rotation part and the axis of the nozzle or in parallel with the plane.

Further, only the cover of the visible light transmitting means is mounted on the nozzle, the nozzle mounting part or the water cannon rotating part equipped with the fire extinguisher fire extinguisher, and the visible light transmitting means is placed in the cover during the test. It can be worn.

[0009]

By mounting the laser beam transmitting means on the water cannon fire extinguisher so as to generate visible light in a vertical plane including the direction of water discharge, visible light such as laser light is transmitted in the same direction as the direction of water discharge during the test. be able to. Therefore, at the time of maintenance or periodic inspection, the test can be performed without actually discharging water, so that the problem of water loss can be avoided.

As shown in FIGS. 14B, 14C and 14D, the discharged water does not fall on the place where the visible light such as the laser light hits, but the place where the visible light hits depends on the water discharge direction. Since they are in the same vertical plane, if necessary, the landing position can be determined by checking the relationship between the water discharge elevation angle and the range in advance.
