In general, in order to prevent the spread of a large-scale fire, various types of firefighting equipment are installed in buildings including apartment houses and various underground facilities, and a water supply pipe for supplying extinguishing fluid to the firefighting equipment is constructed.

Fire hydrants and sprinklers are representative firefighting equipment, and these firefighting equipment extinguish fires by spraying extinguishing fluid.

However, in most water supply pipes, one firefighting equipment installs multiple firefighting equipment in series to supply water, so in case of emergency, firefighting equipment adjacent to the water supply source is capable of repelling the extinguishing liquid with sufficient water pressure, but firefighting equipment located far from the water supply source will cause fire. The water repellency of the water pressure insufficient for suppression is made.

Moreover, since a sufficient amount of extinguishing liquid cannot be supplied with firefighting equipment with low water pressure, fire suppression itself becomes impossible.

1 is a partial cross-sectional view illustrating a fire prevention piping apparatus for preventing fire spread according to the present invention, and FIG. 2 is an enlarged cross-sectional view of a fire prevention piping apparatus for preventing fire spread according to the present invention.

As illustrated, the fire prevention piping device of the present invention is largely composed of a water supply pipe 10 , a nozzle housing 20 , a step motor 30 , a lifting block 40 , a valve body 50 , and a spray nozzle 60 . It is composed of a combination.

The present invention is a configuration applied to an apartment house or a private house, and is formed along the curtain rail groove 100 in the interior of a window that separates the interior and exterior in particular.

In general, the curtain rail groove 100 is formed so that the end of the window or veranda window side from the ceiling surface 200 is upwardly concave with a predetermined length and width.

A rail bracket for curtain installation, a curtain installation rod fixing bracket, or a rail for direct curtain installation is fixed to the ceiling surface 200 indented upward of the curtain rail groove 100 by screw coupling.

The water supply pipe 10 is disposed on the upper portion of the ceiling surface 200 of the curtain rail groove 100 in the longitudinal direction.

The nozzle housing 20 is connected at regular intervals to the water supply pipe 10 installed along the upper portion of the ceiling surface 200 of the curtain rail groove 100 .

The nozzle housing 20 has a circular or polygonal tubular shape having a predetermined height, and a water supply pipe 10 is connected to an outer circumferential surface of the predetermined height.

The nozzle housing 20 is connected to the water supply pipe 10 by horizontally penetrating the nozzle housing 20 at a certain height while vertically penetrating downward.

A step motor 30 is connected to each of the upper ends of the nozzle housing 20 .

The step motor 30 is configured to rotate forward and reverse at a predetermined number of rotations, and the operation of the step motor 30 is controlled by the controller 31, and the controller 31 is provided to detect a fire. The operation signal is controlled by a signal checked from the sensor 32 .

The controller 31 is connected to control each of the plurality of step motors 30 , and a fire detection sensor 32 is connected to the controller 31 .

The sensor 32 for detecting fire may use a sensor installed in an existing room, but it is preferable to install one or more sensors on the ceiling by the window. It may be configured to detect temperature, or may be configured to detect flame.

The signal sensed by the fire detection sensor 32 is checked by the controller 31 to control the operation of the step motor 30 by comparing it with a previously set temperature or flame size.

The lifting block 40 is inserted into the upper end of the nozzle housing 20 .

The lifting block 40 has a corresponding thread formed on the outer peripheral surface so as to be screwed to the thread formed on the upper inner peripheral surface of the nozzle housing 20, and the driving shaft 30a drawn out from the step motor 30 on the upper part. to be inserted.

The drive shaft 30a allows a plurality of blades or blades to be integrally formed in a radial direction so that the lifting block 40 can rotate at the same time as in FIG. 3, and the plurality of blades or blades are integrally formed in the lifting block 40 It is custom-coupled to be separable from the drive shaft 30a formed by the elevating block 40 to lower or rise to a certain height while rotating.

Accordingly, the lifting block 40 is rotated in the forward or reverse direction by a predetermined number of revolutions by driving the step motor 30 to descend or rise to a predetermined height.

A valve body 50 is provided at a lower portion of the elevating block 40 to elevate in conjunction with the elevating block 40 .

However, the valve body 50 allows the upper end to contact the lower end of the elevating block 40 while preventing rotational force transmission even when the elevating block 40 rotates while simultaneously performing only elevating action.

To this end, the lower end of the lifting block 40 in contact with the upper surface of the valve body 50 is in point contact so as to be in contact with the valve body 50 to a minimum, as shown in the illustrated figure, so that lifting is possible, but the rotational action is not transmitted. Preferably, the valve body 50 is formed in a square or polygonal shape as shown in FIG. 4 rather than a circular shape so that only lifting is possible inside the nozzle housing 20, and the valve body 50 has a circular shape. In the case of forming, one or more blades are formed on the outer circumferential surface as in the elevating block 40 , and insertion grooves can be formed on the inner circumferential surface of the nozzle housing 20 so that the blades can be inserted.

In addition, it is preferable that the valve body 50 is formed as a height of at least twice the diameter of the water supply pipe 10 .

In the valve body 50, the through hole 51 is formed in the upper or lower part with the same diameter as the inner diameter of the water supply pipe 10 on the basis of the middle of the height, while the through hole 51 is again penetrated downward to form a T-shape. do.

Accordingly, the through hole 51 of the valve body 50 communicates with the water supply pipe 10 so that the fire extinguishing water supplied through the water supply pipe 10 is supplied through the valve body 50 .

On the other hand, the lower portion of the valve body 50 so that the injection nozzle 60 is formed.

The spray nozzle 60 is provided with an upper end in close contact with the lower end of the valve body 50 between the cross-sections while being formed at a certain height to elevate the inside of the nozzle housing 20 , and the lower end protrudes to the lower part of the nozzle housing 20 . The nozzle head 61 is formed so that the upper end of the nozzle housing 20 and the lower end of the nozzle housing 20 are elastically supported by the coil spring 62 inside the nozzle housing 20. .

Therefore, the spray nozzle 60 is sprayed by pushing the spray nozzle 60 upward with a certain elasticity while making the nozzle head 61 close to the lower end of the nozzle housing 20 by the elastic force of the coil spring 62 . The upper end of the valve body 50 provided above the nozzle 60 is always in surface contact with the lifting block 40 .

A nozzle hole 60a is vertically formed in the spray nozzle 60 to communicate with a through hole 51 formed vertically of the valve body 50 , and the nozzle hole 60a is formed in the nozzle head 61 . The radially downward branch is made to communicate with the injection hole 61a.

On the other hand, it is most preferable to connect the lower end of the valve body 50 and the upper end of the spray nozzle 60 in a stepped manner to prevent leakage of fire water to the outside while allowing the fitting to be coupled to each other.

The operation and effect of the fire prevention piping device for preventing the spread of fire of the present invention according to the above configuration will be described in more detail as follows.

As shown in FIG. 5, the fire prevention piping device of the present invention has one feature in that it is formed on the window side, which is formed to communicate with the outside in a room or living room of a house.

In particular, a curtain rail groove 100 for installing a curtain is usually formed on the window side, and a plurality of sprinklers are installed on the ceiling surface 200 of the curtain rail groove 100 .

In addition, in the present invention, the nozzle head 61 for substantially spraying fire water from the spray nozzle 60 is usually formed in parallel with the ceiling surface 200 of the curtain rail groove 100, but only when a fire occurs. Another feature is to prevent the spread of fire through the window by allowing the fire water to be sprayed through the plurality of spray holes 61a formed in the nozzle head 61 by protruding downward from the 200 by a certain height.

To describe this in more detail, as shown in FIG. 6 , if the conventional sprinkler does not operate or is operated due to the occurrence of a fire in the room, the fire cannot be extinguished by the sprinkler and the fire becomes large, the fire usually starts to spread to the window side.

At this time, when a fire is detected by the fire detection sensor 32 provided on the window side, the step motor 30 fixed to the upper end of each nozzle housing 20 is driven by the controller 31 .

The step motor 30 rotates only by a certain number of revolutions, and the lifting block 40 is rotated by the rotation of the driving shaft 30a drawn out from the step motor 30 and at the same time it moves downward by a certain height.

When the lifting block 40 descends, the valve body 40 is lowered so as to be in surface contact with the lower end of the lifting block 40, and so that the valve body 40 is in surface contact with the lower end of the valve body 40 by the lowering of the valve body 40. One injection nozzle 60 is moved downward.

Since the spray nozzle 60 descends while compressing the coil spring 62 between the lower end of the nozzle housing 20 and the nozzle head 61 formed at the lower end of the spray nozzle 60, the ceiling surface 200 It moves downward to the lower part of the curtain rail groove 100 from the

As the lifting block 40, the valve body 50, and the injection nozzle 60 descend by the rotation of the step motor 30 in this way, the through-hole 51 formed in the valve body 40 is mutually with the water supply pipe 10 . When it is in communication state, the fire water guided from one side of the water supply pipe 10 is formed in the spray nozzle 60 together with the T-shaped through-hole 51 formed in the valve body 50 and the nozzle hole 60a and the nozzle head ( It is to be sprayed downward through the injection hole 61a formed in 61).

When the fire water is sprayed to the window side through the injection hole 61a, the spread of the fire spreading to the window side is prevented.

Since fire has a property of spreading in a direction with a lot of oxygen, it naturally spreads to the window side indoors, and the spread of fire through the window spreads to a larger area through the outside, causing damage to increase.

Therefore, if the fire extinguishing water is sprayed toward the window as in the present invention, there is a very useful effect of being able to easily extinguish the fire induced to the window and at the same time prevent further damage.

As such, the present invention is not limited to the described embodiments, and it is apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Accordingly, it should be said that such modifications or variations are included in the claims of the present invention.
