Description

FIREFIGHTING SPRINKLER APPARATUS AND APPARATUS USING ELECTRIC APPARATUS

The present invention relates to a sprinkler device using an electric device of a apartment house, and more particularly to a sprinkler device capable of selectively down-warding and evolving in a residential space when a fire occurs in a household of the apartment house, By spraying the water toward the ceiling and the wall, it is possible to evolve the fire spread to the ceiling and the wall, and to prevent the fire from spreading to the next generation in an instant by the heat by preventing overheating of the ceiling and the wall. The present invention relates to a fire-extinguishing sprinkler device using an electric device of a fire extinguisher.

Conventional housing fire fighting sprinkler devices include a fire detector and a sprinkler head installed in each household. When a fire occurs, the fire signal from the fire detector causes the fire extinguishing water supplied from the fire source to sprinkle through the sprinkler head, .

The conventional sprinkler head is connected to the lower end of the tube portion through a fuse and normally closes the tube portion. When the fuse is melted by heat when a fire occurs, the sprinkler head is separated from the tube portion and descends by its own weight, By including the reflector for diffusing the water, the water to be sprayed in the sprinkler head is diffused downward while diffusing in the horizontal direction.

As a prior art related to this, Korean Patent No. 10-0434984 (registered on May 28, 2004) "wet sprinkler device" is used to ensure a fire operation by a quick sprinkler in the event of a fire, Wherein a suction pipe is provided so as to communicate with an upper position of a secondary pipe portion of a water supply pipe constituting a water supply passage from a water supply means to a sprinkler head and a suction pipe is provided in the secondary pipe portion, Side piping section from the upper position of the secondary piping section, and these suction pipes, suction means, and solenoid valves constitute a vacuum pressure securing section. Then, the water in the secondary piping section which normally puts the water filled state becomes a negative pressure by the suction operation of the suction means, and when the negative pressure state becomes a normal state and the sprinkler head malfunctions, So that the water in the tank is not discharged in a useless manner.

Generally, when a fire occurs in apartment house, it is spread directly by flame. However, in many cases, it spreads to neighboring households instantaneously due to the heat inside the house where the fire occurs. The fire water that is sprinkled in the conventional sprinkler head spreads horizontally So that the water is not sprayed to the ceiling and the wall, so that there is a problem that the fire spreads to adjacent households due to heat.

Therefore, it is possible to prevent overheating of the ceiling and the wall by means of spraying means for spraying fire water to the ceiling and the wall together with the sprinkler head which evolves the fire as the fire water is sprayed horizontally when a fire occurs in the household of the apartment house. It is required to develop a technique for preventing fire from spreading to adjacent households.
