Abstract

PROBLEM TO BE SOLVED: To prevent an adjacent sprinkler head from being sprinkled by providing the equipment with a regulator regulating the water aiming distance of extinguishing water aimed in a prescribed direction from a sprinkler head for a head protector. SOLUTION: The regulator 14 is attachably/detachably disposed between a pair of guard supporters 13 opposed to the adjacent sprinkler head among the guard supporters 13 of the head protector 9. This regulator 14 regulates the water aiming distance of extinguishing water aimed in the direction of the adjacent direction to keep the adjacent sprinkler head out of the sprinkling of extinguishing water. Namely, this regulator 14 is provided with water aiming direction regulating plates 17a to 17c to aim the water aiming direction obliquely downward like an arrow A. These plates 17a to 17c are provided with vertical intervals to form side plates at both ends. Thereby, the water aiming distance is restricted to prevent the adjacent sprinkler head from being sprinkled to sufficiently show extinguishing performance.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a sprinkler fire extinguishing system installed in a building such as a building.

[0002]

2. Description of the Related Art In recent years, sprinkler heads of sprinkler fire extinguishing equipment installed in buildings, houses, and the like have come to use a wide sprinkling area in order to enhance fire extinguishing ability. In particular, sprinkler heads used for houses are designed to have sufficient water for fire extinguishing on furniture and curtains placed on the indoor wall side to prevent fire from spreading from the wall side. It is expanded or fire fighting water is allowed to reach far away.

[0003]

However, in a conventional sprinkler fire extinguishing system equipped with such a sprinkler head, fire extinguishing water, which is scattered as small particles from the deflector of the sprinkler head, is subject to air resistance and other factors during the range. If the mist collides with particles of the water and becomes mist, and the mist spreads on the airflow generated by the water spray, fire extinguishing water may adhere to the adjacent sprinkler head. In particular, when the door of the room is opened while water for fire fighting is being sprayed, turbulence of airflow occurs. And there was a risk that the intended fire-fighting capacity could not be fully exhibited.
Even if the sprinkler head is not installed in a house, the same problem may occur if the sprinkler heads are installed at narrow intervals, if the sprinkler heads are installed by tilting by mistake, or if the sprinkler heads are deformed by hitting the deflectors. There was a fear that it would occur.

The present invention has been made in view of the above points, and can prevent fire-extinguishing water sprinkled from a sprinkler head from falling on an adjacent sprinkler head.
An object of the present invention is to provide a sprinkler fire extinguishing system that can sufficiently exhibit an intended fire extinguishing ability.
