Abstract

PURPOSE: A sprinkler head for controlling the length is provided to reduce damage due to fire by quickly sensing the fire. CONSTITUTION: A sprinkler head controls the length of an outer body(1) and an inner body(2) of a sprinkler according to a building and the fire and moves the inner body and the outer body. A heat connector(4) is formed on the lower side of a sprinkler installed on a ceiling. If a fire occurs, the heat connector is separated from the sprinkler body and a reflection plate(3) is protruded to the lower side of the ceiling due to water pressure. Water(5) for fire-fighting is spread on a fire area by being reflected to the reflection plate.

Description

Sprinkler Head for Length Adjustment {AUTO SPRINKLER HEAD}

The present invention relates to a sprinkler head, in general, heat generated when a fire occurs is transferred to the upper part of the building, and the heat connector (4) below the sprinkler head installed on the ceiling (8) is separated from the sprinkler head body by the heat of fire, and then inside the head. The installed reflection plate 3 protrudes to the lower part of the ceiling 8 by the hydraulic pressure of the pump, and the extinguishing water 5 is reflected on the reflecting plate 3 so that the extinguishing water 5 is sprayed to the fire place for extinguishing activity. When installing the sprinkler head, as shown in the table below, it is prescribed in the Fire Code to be installed based on the sprinkler head installation criteria.

The center of the reflector on the sprinkler head
Horizontal distance of beam The height of the reflector on the sprinkler head
Vertical distance of bottom height of beam Less than 0.75m Lower than the bottom of the beam 0.75m to less than 1m Less than 0.1m 1 m to less than 1.5 m Less than 0.15m 1.5m or more Less than 0.3m

In general, sprinkler heads installed in buildings are fire-extinguishing facilities that are fixed to the ceiling (8) to prepare for fire. When the building ceiling (8) is a well ceiling (7), the sprinkler head is installed in accordance with the sprinkler head installation criteria. The sprinkler head is inevitably installed at the bottom of the well ceiling (7) in order to meet the horizontal distance between the center of the reflector (3) and the beam. After the heat is concentrated on the well ceiling (7), the top of the building, heat is transferred to the ceiling (8), and then the heat connector (4) installed on the ceiling (8) senses heat and escapes the head body to extinguish the fire. In addition, the fire extinguishing time is delayed and the sprinkler pipe from the well ceiling (7) to the ceiling (8) is exposed to damage the building aesthetics.

The horizontal distance between the center of the reflector (3) and the beam of the sprinkler head based on the sprinkler head installation criteria is determined by the heat connector (4) of the sprinkler head that detects the fire when the fire breaks out, and then the extinguishing water (5) passes through the reflector (3). It is a regulation to prevent sprinkling disturbances around when spraying to a fire place, and it does not deviate from this regulation and detects fire heat more quickly in case of fire, so that fire extinguishing activity is quick and safe structure to minimize human injury and economic loss caused by fire. In order to reduce the length to provide a sprinkler for adjusting the length {AUTO SPRINKLER HEAD}.

Length adjustment sprinkler head complementing the existing sprinkler head installed on the ceiling 8 of the indoor building {AUTO SPRINKLER HEAD} is to adjust the length of the sprinkler head outer body (1) and the sprinkler head inner body (2) according to the purpose of the building The heat connector (4) is released to the outside due to the heat generated by the first fire by adjusting the length, and the sprinkler head inner body (2) and the reflector (3) pass through the well ceiling (7) by the hydraulic pressure of the pump (8). Fire extinguishing water is reflected on the reflecting plate (3) and the fire extinguishing water (5) is sprayed to the fire place to extinguish the fire. When extinguishing, the sprinkler head inner body (2) is released to the lower part and the sprinkler inner body (2). ) Because the reflection plate (3) attached to the lower part reaches the firearm as close to the firearm as the length of the sprinkler inner body (2), the fire extinguisher may be more desirable than the existing sprinkler head. In the case of installing the well ceiling 7 in the interior of the well, in the case of installing the sprinkler head for adjusting the length {AUTO SPRINKLER HEAD} of the present invention in the well ceiling 7, the heat of the fire is more than that of the ceiling (8). Heat is concentrated in the 7) can shorten the time that the heat connector (4) is separated from the head body.

If the sprinkler for adjusting the length {AUTO SPRINKLER HEAD} is installed on the well ceiling (7), the heat generated when a fire occurs is detected earlier than the existing sprinkler head, so that the heat collector (4) leaves the outside and the sprinkler head inner body (2). And the reflecting plate (3) protrudes below the ceiling (8) through the well ceiling (7) by the hydraulic pressure of the pump and the extinguishing water (5) is reflected on the reflecting plate (3) and the extinguishing water (5) is injected into the fire place When fire extinguishing, sprinkler head inner body (2) is separated from the lower part during fire extinguishing, and then the reflector (3) attached to the lower part of sprinkler inner body (2) reaches the firearm as close as the sprinkler inner body (2). Therefore, if you want to extinguish more than the existing sprinkler head, and also in the nature of the building if the well ceiling (7) installed in the ceiling ceiling length adjustment sprinkler head {AUTO SPRINKLER HEAD} of the present invention well ceiling (7) When installed in the fire, the heat of the fire is concentrated on the well ceiling (7) rather than the ceiling (8), and the heat connector (4) can be shortened from the head body, so that the fire extinguishing activity can be faster than the existing sprinkler head. It is possible to reduce the life loss and economic loss due to fire to a minimum, and to install the sprinkler head in accordance with the sprinkler head installation regulations when installing the existing sprinkler head. The pipe exposed to the side of the floor compensates for the building aesthetics.

2 is a cross-sectional view of the sprinkler head for adjusting the length of the heat connector 4 when the fire breaks away
Figure 3 is a sprinkler head cross-sectional view for adjusting the length when the sprinkler head inner body (2) is separated in case of fire

FIG. 1 is a cross-sectional view of a sprinkler head for adjusting the length of the sprinkler head, which is usually installed in a well ceiling 7, and has no ceiling exposed from the well ceiling 7 to the ceiling 8 surface. The fire connector detects heat earlier than when it is installed on the ceiling (8) as shown in FIG. 2 by heat moving along the ceiling surface in case of fire, and the heat connector (4) protrudes to the outside and is shown in FIG. As the sprinkler head inner body (2) and the reflecting plate (3) descends to the bottom of the well ceiling (7) at the pressure of the extinguishing water (5), the extinguishing water (5) reaches the firearm through the reflecting plate (3) and extinguish You can do it smoothly.
