対策が急務となっている。[Prior Art] Many wooden buildings are important cultural property buildings.
Many also have a vegetable roof such as thatched roof. Such an important cultural property building often causes a fire due to a falling fire from a bonfire or the like, and measures for early detection and extinguishment of the fire are urgently needed.

Therefore, by letting the water spray from the monitor nozzle linearly reach the surface of the roof, the water penetrates into the interior and the deep fire can be extinguished. Further, by mixing a surfactant or a wetting agent into the water discharge as a chemical agent that promotes the wetting, the penetrating power is improved and the water can be penetrated into the roof.

ズル３が木造建築物２の周囲に複数、具体的には４方向
から屋根や壁に対向している。A monitor nozzle 3 is arranged facing the roof 1 of a wooden building 2 having a thatched roof 1 which is an important cultural property. This monitor nozzle 3 is a jet nozzle 4
And a swivel unit 5 capable of aligning its sights vertically and horizontally. And this monitor nozzle 3
The arrangement is such that the water discharge from the water discharge nozzle 4 does not dissipate, it is opposed by a short distance of about half the reach of the water discharge, and the vigorous water reaches the roof 1 linearly, and even to the deep part of the thatched roof 1. It is supposed to penetrate. In addition, a surfactant is mixed in the water to be discharged, and the thatched roof 1
Increasing the penetration power inside. A plurality of such monitor nozzles 3 are provided around the wooden building 2, specifically, facing the roof or wall from four directions.

にまで浸透する。Explaining the water discharge pattern of the jet nozzle 4, the range L2 of the nozzle is the distance that the water discharged from the nozzle reaches. Then, the water discharged from the nozzle at a predetermined angle initially spreads and progresses in a rod shape, but when the spread gradually increases and the momentum disappears, the water begins to descend and falls within the spray range to the range L2. Water without the same force as a free fall falls. In this embodiment, of the water discharged from the nozzles, the range with momentum is set as the effective range distance L1, and the distance to the wooden structure 2 as the fire prevention target is set to be shorter than the effective range distance L1. As a result, the water discharged from the jet nozzle 4 linearly reaches the thatched roof 1 and permeates to the deep part of the thatched roof 1 due to the force of the water discharge.

ズルや水噴霧システムであっても効果的である。In addition, a wetting agent is mixed in the sprinkling water of this embodiment, and in this embodiment, as a wetting agent that reduces the interfacial tension between the liquid and the solid to give an osmotic force, the main component is an alkyl sulfate amine. A 3% mixed solution of the synthetic surfactant type foam extinguishing agent (No. NCS-312, Nomi Disaster Prevention Co., Ltd.) is used. And the drug is not limited to the above,
Any substance such as sodium alkylnaphthalene sulfonate, polyoxyethylene alkyl ether, or the like that exerts the above-mentioned action on the interface may be used. Of course, the use of such an agent is effective even in a monitor nozzle or a water spray system which is normally installed other than this embodiment.

を消火することができる。As described above, according to the first aspect of the present invention, the monitor nozzle is arranged facing the surface of a plant building such as a wooden building at a distance shorter than the reaching distance thereof, and the water discharge from the monitor nozzle is linear. Since it reaches the plant-based building surface, the water can permeate into the plant-based building surface due to the force of the water discharge, and the deep fire can be extinguished.

る。Further, in the third invention, the monitor nozzle is arranged so as to face the surface of the plant-based building such as a wooden building at a distance shorter than its reaching distance, and the water discharged from the monitor nozzle is linearly applied to the surface of the plant-based building. As it arrives, the water discharged from the monitor nozzle contains a chemical that promotes the infiltration of the plant-based building surface, so the water's momentum causes the water to penetrate into the plant-based building surface, increasing the water penetration power. Since it is improved, it can penetrate more effectively and extinguish deep fires.
