Description

SPRINKLER HEAD INSTALLED IN CEILING SPACE}

The present invention relates to a sprinkler head, and more particularly, to a sprinkler head between a ceiling and a half-circle capable of efficiently extinguishing a fire generated in a space between a ceiling and a half-circle inside a building.

In general, a sprinkler is installed inside a building so that it can be extinguished early by spraying fire water when a fire occurs.

Specifically, the sprinkler facility includes a pipe connector connected to a main pipe provided along the interior of the ceiling of a building, and a sprinkler head that is coupled to the end of the pipe connector and the end penetrates the ceiling and is installed to be exposed to the room. Can include.

For such a sprinkler facility, it has been previously applied as Korean Patent Publication No. 10-2007-0059890 (published date: 2007.06.12.).

However, conventional sprinklers are usually installed on the ceiling of a building to operate in connection with a temperature sensor, and these sprinklers are installed in a top-down manner, that is, the spraying direction of water for fire extinguishing toward the indoor floor (downward).

That is, in most buildings, a space between the ceiling and the half-shape is formed, and facilities necessary for life such as air conditioning ducts, fire pipes, and electric wire wiring are installed in the space.

In this case, there is a problem in that it is difficult to initially extinguish a fire when a fire occurs due to a short circuit such as electric wiring installed in the space between the ceiling and the half-circle.

In particular, in accordance with the provisions of Article 9, Paragraph 1 of the'Act on Fire Prevention, Attraction, Maintenance and Safety Management of Fire Fighting Facilities,' It is a situation where a sprinkler needs to be installed in the space.

In addition, in order to prevent freezing of the piping of the fire extinguishing facility, an insulating material for piping of inorganic and organic systems is applied to the pipe. However, the pipe insulation used in the fire extinguishing system has no standard for the performance of the flame retardant material, so there is confusion over what material to use as the insulation of the fire extinguishing facility in the process of building design, supervision, and construction. Therefore, when a fire occurs, the fire may be spread by a pipe insulation material with poor flame retardant performance, and accordingly, there is a problem that it may cause difficulty in extinguishing the fire.

The present invention has been conceived to solve the above-described problem, and an object thereof is to provide a sprinkler head installed in a space between a ceiling and a half-circle to efficiently extinguish a fire generated in the space initially.

The deflector may include a body portion formed in a plate shape having a predetermined curvature; And a first injection unit through which a plurality of injection holes are formed in the body portion so that the fire water supplied through the water outlet may be injected toward the ceiling side.

In this case, the injection holes may be arranged to be spaced apart from each other by a predetermined angle around the central axis of the body part.

In addition, the injection holes may be symmetrically disposed on both sides about the central axis of the body part.

In addition, the injection hole may be arranged to be skewed toward one side so as to inject fire water toward a predetermined point on the ceiling.

In addition, the injection hole may be formed to be inclined at a predetermined angle so that the supplied fire water can be injected at a predetermined angle.

Further, at the edge of the body portion, a second spraying portion in which a plurality of protruding blades are formed to be spaced apart by a predetermined angle so that the fire water supplied through the water outlet can be sprayed in all directions; further comprising, the protruding blades are arranged in a vertical zigzag pattern. It is formed to be bent at a predetermined angle so that the injection range and the injection angle of the supplied firefighter can be expanded.

In addition, the plurality of protruding blades may be individually bent angles can be specified.

The sprinkler head according to the present invention having the above configuration, by installing the sprinkler head in the space between the ceiling and the half-circle, by forming a first injection portion and a second injection portion on the deflector provided at the end of the sprinkler head, in the space In the event of a fire, it is possible to inject the fire water in various spraying ranges and spray angles, and accordingly, there is an advantage in that the fire generated in the space can be extinguished efficiently at an early stage.

The head body 110 is provided with an inlet 111 and a water outlet 113 so that the fire water supplied through the water supply pipe 10 can enter and exit. The head body 110 having this structure may be disposed such that the outlet 113 faces the ceiling 1 (upper side) in the space S.

For reference, the sprinkler head 100 applies a high pressure to the supplied fire water to inject the fire water in a circular shape, and when a fire occurs, the heat-sensitive part 101 made of an alloy or glass bulb is destroyed at a predetermined temperature and at the same time, the inlet 111 It is a method of spraying in all directions while hitting the deflector 120, which will be described later, by the fire water supplied through the and the outlet 113. The operation method of the sprinkler head 100 provided with the heat-sensitive part 101 is generally applied and used, and a detailed description thereof will be omitted.

The deflector 120 is installed spaced apart from the water outlet 113 of the head body 110 in the direction in which the fire water is sprayed, and the deflector 120 is sprayed in all directions while the fire water supplied through the water supply pipe 10 collides. It reflects the firefighter so that it can be done.

4, the deflector 120 is formed in a plate shape having a predetermined curvature, and the body portion 121 formed spaced apart from the outlet 113 through the support 121a, and the outlet 113 A first injection unit 123 through which a plurality of injection holes 123a are formed through the body 121 so that the fire water supplied at a predetermined pressure can be injected toward the ceiling (1) side (upper side), and the water outlet Includes a second spraying part 125 in which a plurality of protruding blades 125a are formed to be spaced apart by a predetermined angle on the rim of the body part 121 so that the fire water supplied through the 113 can be sprayed in all directions (horizontal direction). can do.

The configuration of the deflector 120 will be described in more detail with reference to FIG. 5 as follows.

First, a plurality of injection holes 123a of the first injection unit 123 may be disposed at a predetermined angle with respect to the central axis of the body unit 121 as an example (Fig. 5(a)). Reference).

That is, as the plurality of injection holes 123a constituting the first injection part 123 are arranged at a certain angle with respect to the central axis of the body part 121, the firefighter sprayed through the injection hole 123a It is possible to uniformly spray toward a certain range of the ceiling side in the temporary space (S).

In this case, the diameter of the spray hole 123a may be changed and applied in various ways according to a range or pressure in which firefighting water is sprayed, as shown in FIGS. 6 and 7.

In another embodiment, as shown in FIG. 8, the injection holes 123a may be symmetrically disposed on both sides about a central axis of the body portion 121 (not shown).

That is, as the injection holes 123a are symmetrically disposed on both sides of the body portion 121, it is possible to intensively spray fire water at a predetermined point above the sprinkler head 100.

In another embodiment, as shown in FIG. 9, the injection hole 123a may be arranged to be skewed toward one side so as to spray fire water toward a predetermined point of the ceiling 1.
Specifically, the injection hole (123a) is arranged to be biased to one side based on the virtual center line dividing the body portion 121 into both sides, the two injection holes in contact with the center line are rounded toward the direction in which the firefighter is sprayed. It is formed in a semi-circular shape (see (a) of FIG. 9), and the remaining injection holes arranged to be skewed toward one side may be formed in a circular shape.

That is, installations such as a plurality of pipes, wires, and other subsidiary materials are provided in the space (S) between the ceiling (1) and the half-length (3), and sprayed through the sprinkler head 100 when a fire occurs in the space (S). There are cases in which it is difficult to spray the fire-fighting water to every corner of the installation.

Therefore, considering the situation of the installation installed in the vicinity of the point where the sprinkler is installed in the space (S), by disposing the injection hole 123a provided in the sprinkler head 100 to one side, the fire is efficiently extinguished. I can do it.

In addition, the injection hole 123a may be formed to be inclined at a predetermined angle so that the fire water supplied through the water outlet 113 of the head body 110 can be injected at a predetermined angle (not shown).

In another embodiment, as illustrated in FIG. 10, the protruding blades 125a constituting the second injection unit 125 may be formed to be bent at a predetermined angle so that they can be arranged in a vertical zigzag.

That is, as the protruding blades 125a are formed to be bent up and down, the spraying range and spraying angle of the firefighting water supplied through the outlet 113 of the head body 110 can be variously expanded.

In other words, by setting the protruding blades 125a at various angles, firefighting water can be sprayed at various angles into various pipes installed in the space (S) between the ceiling (1) and the half-length (3) or between electric wiring. Therefore, initial extinguishing is possible when a fire occurs.

In this case, the plurality of protruding blades 125a may be individually bent at an angle. That is, depending on the position of the sprinkler installed in the space (S) between the ceiling (1) and the half-length (3), the angle of the protruding blade (125a) of the second spraying unit (125) can be formed differently, accordingly. The fire water sprayed through the sprinkler head 100 may be set to face a predetermined point.

The sprinkler head 100 between the ceiling and the half-width according to the present invention having the above configuration, but the sprinkler head 100 is installed in the space S between the ceiling 1 and the half-width 3, and the sprinkler head 100 By forming the first injection unit 123 and the second injection unit 125 on the deflector 120 provided at the end of, as shown in FIG. 11, when a fire occurs in the space (S), various firefighters are sprayed. It is possible to spray with a range and spray angles (θ1, θ2). Accordingly, it is possible to efficiently extinguish the fire generated in the space (S) initially.

In the above, the present invention has been illustrated and described with reference to specific specific embodiments, but the present invention is not limited to the above-described embodiments, and various changes and modifications can be made without departing from the spirit of the present invention.
