Description

  The present invention has a multistage boom that can be expanded and contracted, and can discharge water at a pinpoint from a water discharge nozzle connected to the tip of a water supply pipe, for example, from the upper side to the lower side of a fire point of a building. Related to cars.

  In general, a fire truck with a water discharge tower has a water nozzle attached to the tip of the water discharge tower, and discharges water from the water nozzle toward a fire spot in a building. The fire engine is equipped with a water pump driven by its engine, and water pressurized by the water pump is supplied to the water nozzle through a pipe. In this case, a large amount of water is discharged from the water nozzle and extends not only to the fire spot but also to the surrounding area. For this reason, buildings are damaged by water, and it is necessary to thicken pipes to send a large amount of water and to strengthen the water discharge tower to support the reaction of water, resulting in an increase in the size of fire engines. There was a problem.

  In order to solve such a problem, a fire-fighting pump vehicle with a high-pressure spray water tower described in Patent Document 1 has been proposed. That is, this fire pump automobile is equipped with a high-pressure pump and is configured to discharge spray-like ultrafine water particles at a higher pressure than the spray nozzle provided at the tip of the refraction-type water discharge tower. Furthermore, the tip of the water discharge tower is a telescopic type, and the spray nozzle can enter the indoor space to spray and discharge water indoors.

Japanese Patent Laid-Open No. 11-128383

The water pipes 16 communicated in order. As shown in FIG. 4, an end water supply pipe 20e as a fifth boom is connected to a water supply pipe 16 held by the fourth boom 20d at the tip of the fourth boom 20d. A front semicircular guide member 29 is attached to the upper portion of the end water pipe 20e, and the tip of the end water pipe 20e is guided in an arc along the upper surface of the guide member 29. The tip of the water supply pipe 20e is configured to face downward.

  A water discharge nozzle 31 is attached to the tip of the end water pipe 20e via a drive member (motor) 30, and the water discharge nozzle 31 can be changed in its water discharge angle by the drive member 30. ing. The water discharge nozzle 31 has a plurality of water discharge forms such as a bar-shaped water discharge, a mist water discharge with a water discharge angle of 30 degrees, a mist water discharge with a water discharge angle of 60 degrees, and a mist water discharge with a water discharge angle of 90 degrees. The drive member 30 is driven by the signal so that the water discharge mode can be changed. The water discharge nozzle 31 is configured to discharge water from the upper side to the lower side with respect to the fire spot (fire source) 17 of the building 32.

  A camera 33 is attached to the side of the water discharge nozzle 31 so that the fire state at the fire spot 17 can be photographed from the position of the water discharge nozzle 31. The camera 33 is moved together with the water discharge nozzle 31 by the driving member 30 so that the photographing direction can be changed. The control nozzle 21 operates the water discharge nozzle 31 and the camera 33 by operating the remote controller 25 of the fire brigade 23, and changes the water discharge angle of the water discharge nozzle 31 and the shooting direction of the camera 33 by remote control. It is configured to be able to. And the image | video image | photographed with the camera 33 is displayed on the screen 25a of the remote control 25 which the fire brigade member 23 has.

  In the control device 21, the first boom 20 a turns, the booms 20 a, 20 b, 20 c, and 20 d extend, the water discharge nozzle 31 and the camera 33 rotate by driving the driving member 30, and the water discharge nozzle 31 discharges water. The change and the like are controlled under conditions set in advance by the remote controller 25, and the water pressure, the amount of water, and the like are controlled.

Next, the effect | action of the water discharge vehicle 10 for fire fighting comprised as mentioned above is demonstrated.

As shown in FIG. 3, when the fire-fighting water truck 10 arrives at the fire site, the fire-fighting water truck 10 is stopped at an appropriate position close to the fire spot 17, where the outrigger 19 is extended and grounded. The water discharge vehicle 10 is stabilized. In this state, the fire brigade 23 operates the remote controller 25 to drive the hydraulic cylinders 27 between the booms 20a, 20b, 20c, and 20d by the control device 21, and the booms 20a, 20b, 20c, and 20d go straight diagonally upward. Operate to extend. Furthermore, as shown in FIG. 4, the water discharge nozzle 31 at the tip of the end water pipe 20 e formed in an arc shape along the guide member 29 is positioned above the opening 35 where the roof 34 of the building 32 has disappeared, The tip of the water discharge nozzle 31 is operated so as to face downward.

  In this state, when the fire brigade 23 operates the remote controller 25 to drive the high-pressure pump 15, the water in the water storage tank 13 passes through the water supply pipe 16 and is discharged from directly above the fire spot 17 by the water discharge nozzle 31. Is done. As described above, since the water can be directly discharged at the pinpoint so as to go to the flame 36 rising from the fire spot 17, the rising momentum of the flame 36 can be effectively suppressed with a small amount of water.

  In addition, the fire brigade member 23 can operate the remote controller 25 to operate the camera 33 attached to the water discharge nozzle 31 and visually recognize the state of the flame at the fire spot 17 on the screen 25a of the remote controller 25 to determine. . For this reason, the fire brigade member 23 can extinguish the flames 36 in order by changing the water discharge angle of the water discharge nozzle 31 in accordance with the movement of the flame 36, changing the water discharge form, or changing the water discharge amount. .

  In addition, when the fire brigade 23 determines that a fire extinguishing agent is necessary for extinguishing an oil fire or the like, the fire extinguishing agent is injected from the fire extinguishing agent tank 18 into the water supply pipe 16 by operating the remote controller 25 and operating the control device 21. To do. The fire extinguishing agent injected into the water supply pipe 16 is mixed with water and discharged from the water discharge nozzle 31 together with water.

  When it is desired to change the position of the water discharge nozzle 31 with the movement of the fire spot 17, the fire brigade member 23 turns the first boom 20a and controls the first to fourth booms 20a, 20b, 20c by remote control using the remote controller 25. , 20d expansion and contraction, position change of the end water pipe 20e, angle change of the water discharge nozzle 31, etc. can be quickly performed at hand.
