Description

Panel sprinkler system on the wall

The present invention relates to a wall panel sprinkler system, and more particularly, to a wall panel sprinkler system capable of rapid fire detection and suppression by installing a sprinkler between sandwich panels installed on the wall of a building.

When a fire breaks out in a building with a large number of people, it is difficult to evacuate quickly in a short period of time because many people quickly gather through the narrow evacuation route. In addition, even if a fire was reported to the fire department due to the occurrence of a fire in the building, there was a problem that a large fire engine could not enter the building due to the narrow entrance road, or it was difficult for a fire engine to approach the building due to illegally parked and stopped vehicles around the building.

Accordingly, in recent years, when a building of a certain area or more is built, the installation of a sprinkler in the building is legally obligatory. Therefore, when a fire occurs in a building, the sprinkler installed on the ceiling in the building can quickly detect the fire and immediately extinguish the fire, thereby greatly reducing the loss of life and property due to the fire.

However, despite these advantages, existing sprinklers are often broken down or malfunctioning frequently due to the aging of the building, so that the sprinklers are intentionally turned off in many cases. In this case, even though the sprinkler is installed in the building, when a fire actually occurs in the building, it is often broken or it is difficult to quickly extinguish the fire because the sprinkler is turned off.

In addition, when a sprinkler installed on an existing indoor ceiling of a building extinguishes a fire, if the wall of the building is made of a sandwich panel, the temperature of the wall increases rapidly, and a large amount of toxic gas is emitted from the sandwich panel. There was a problem that the fire suppression was delayed by blocking Won's entry into the building.

In general, for rapid fire suppression, sprinklers are installed on the ceiling of a building. In this case, the sprinklers are often turned off due to frequent failure or malfunction of the sprinklers. For this reason, when a fire occurs in a building, it is difficult to quickly extinguish the fire according to the detection of the fire. In addition, when a fire occurs in a building whose walls are made of sandwich panels, such as a one-room building, the temperature of the wall increases rapidly and releases toxic gas to delay the fire brigade's entry into the building. A technology to detect and extinguish fires was required.

Hereinafter, a wall panel sprinkler system capable of detecting a fire and quickly extinguishing a fire even on a wall of a building in which a sandwich panel is used as a wall will be described in detail with reference to FIGS. 1 to 2 .

1 is a schematic diagram showing a wall panel sprinkler system according to an embodiment of the present invention, and FIG. 2 is a view showing a wall state of a building to which a wall panel sprinkler system according to an embodiment of the present invention is applied.

1 to 2 , the wall panel sprinkler system 100 according to an embodiment of the present invention detects and suppresses fire on the wall of the building when a fire occurs inside a building whose wall is made of sandwich panels. As a possible system, it includes a water supply pipe 120 , a sandwich panel 140 , a spray nozzle 160 , a fire detection sensor 180 , and a control unit (not shown).

The pipes 120 for water supply are respectively disposed and connected to the ceiling, wall, and basement of the building, and a plurality of pipes 120 are arranged in the vertical and horizontal directions to form a lattice structure on the wall, and are connected to a fire hydrant located outside the building.

The sandwich panel 140 is disposed between the pipes 120 for water supply disposed in a grid structure on the wall of the building. The sandwich panel 140 has a structure in which Styrofoam is added to an iron plate, and is mainly used as a building interior material such as a studio due to its low cost. However, despite these advantages, when a fire occurs in the building, the temperature of the iron plate provided inside the sandwich panel 140 rapidly increases, and toxic gas is generated from the Styrofoam.

The injection nozzle 160 is arranged in connection with the water supply pipe 120 at each intersection of the water supply pipe 120 arranged in the vertical and horizontal direction on the wall of the building, so that the fire detection sensor 180 is When fire is detected, water is sprayed.

The fire detection sensor 180 is disposed to protrude to the outside on the water supply pipe 120 disposed on the wall of the building, detects whether a fire has occurred, and generates a fire detection signal according to the detection result and transmits it to the control unit do. A plurality of these fire detection sensors 180 may be disposed in pairs with the injection nozzle 160 disposed on the wall surface.

The control unit controls the injection nozzle 160 to operate according to the fire detection signal received from the fire detection sensor 180 . When some of the jet nozzles among the plurality of jet nozzles 160 disposed on the wall of the building do not operate, the controller may control the water pressure of the remaining jet nozzles to be higher than a preset reference water pressure. In particular, the control unit can control to discharge water at a water pressure higher than the reference water pressure with respect to the injection nozzles 160 located in the vicinity (eg, up, down, left and right) of a specific injection nozzle that does not operate among all the injection nozzles 160. have. Accordingly, it is possible to quickly extinguish the fire while minimizing the influence of the non-operation of some of the injection nozzles.

Hereinafter, the coupling structure between the water supply pipe and the sandwich panel will be described in more detail with reference to FIGS. 3 to 4 .

3 is a view showing a coupling relationship between a pipe for water supply and a sandwich panel, and FIG. 4 is a view showing a relationship before and after coupling between a pipe for water supply and a sandwich panel.

First, as shown in FIG. 3, the sandwich panel 140 has a structure in which Styrofoam is added to an iron plate, and a semicircular concave groove (h) is formed at the end, so that the groove (h) has a cylindrical shape of water. The supply pipe 120 may be inserted and coupled. In this case, the thickness of the sandwich panel 140 is equal to or greater than the diameter of the water supply pipe 120 . Therefore, when the sandwich panel 140 and the water supply pipe 120 are coupled, the water supply pipe 120 is not exposed to the outside. That is, as shown in FIG. 4( a ), a plurality of water supply pipes 120 are formed on the wall to have a lattice structure with each other, and the water supply pipes 120 arranged in a lattice structure cross each other. At a point where the injection nozzle 160 protrudes from the outside of the water supply pipe 120 . In addition, a sandwich panel 140 is disposed between the water supply pipes 120 formed on the wall in a grid structure. At this time, when the water supply pipe 120 is placed in the center and the sandwich panels 140 disposed on the top, bottom, left and right are moved toward the water supply pipe 120 and coupled, as shown in FIG. 4(b), The water supply pipe 120 is inserted into the groove h formed at the end of the sandwich panel 140 so that the water supply pipe 120 is not exposed to the outside, and only the spray nozzle 160 is inserted into the sandwich panel ( 140) is exposed to the outside.

In addition, a plurality of fire detection sensors 180 may be arranged in pairs with the injection nozzles 160 at positions next to the injection nozzles 160 provided between the sandwich panels 140 .

Hereinafter, a configuration in which a plurality of fire detection sensors 180 arranged in pairs with the injection nozzle 160 are arranged on a wall will be described in detail with reference to FIG. 5 .

5 is a view showing the state of the wall of a building to which a plurality of fire detection sensors are applied to the wall panel sprinkler system of the present invention.

As shown in FIG. 5 , a plurality of water supply pipes 120 are disposed on the wall of a building in the vertical and horizontal directions to form a grid structure. In addition, at the point where the water supply pipe 120 intersects with each other, the injection nozzles 160 protrude outside the water supply pipe 120 and are respectively disposed, and the injection nozzle 160 is next to the injection nozzle 160 . Forming a pair with the nozzle 160, a fire detection sensor 180 may be disposed.

As such, when the plurality of injection nozzles 160 and the fire detection sensor 180 are paired with each other and protrude outside the water supply pipe 120, when a fire occurs only in a local area within the building, the Only the spray nozzle 160 located nearby sprays water to quickly extinguish the fire while minimizing the fire suppression range.

For example, as shown in FIG. 5 , in a state where a total of six injection nozzles 160 and a fire detection sensor 180 are disposed on the wall of a building, when a local fire occurs only at the lower left of the wall, the wall Of the six injection nozzles 161-166 and the fire detection sensors 181-186 installed in the In this case, only the fourth injection nozzle 164 disposed in pairs with the fourth fire detection sensor 184 is opened by the controller to suppress the fire.

For example, when any one of the plurality of fire detection sensors 180 disposed on the wall detects the occurrence of a fire, all of the injection nozzles 161-166 disposed on the wall are opened, including the area where the fire occurred. As a result, the entire room is covered with water, even in areas where there is no fire.

However, as described above, when some fire detection sensors 180 detect a fire occurring in a local area, only the injection nozzles paired with the corresponding fire detection sensor detecting the fire are opened. That is, as water used for fire suppression is sprayed only in the area where the fire occurs, it is located in the same space but is spaced a predetermined distance from the area where the fire occurs, so that water is not sprayed in other areas where there is no fire. Accordingly, it is possible to minimize the damage to property or property while remarkably reducing the processing time in the processing process after the fire suppression is completed.

In addition, when a fire occurs only in a specific local area within the same space, only the injection nozzle located in the fire area is opened to suppress the fire, and some of the injection nozzles located in the vicinity of the fire area are opened to prevent fire. can suppress

To this end, when only a specific fire detection sensor among the fire detection sensors 180 disposed in the building detects a fire, the control unit includes at least one injection nozzle 160 disposed within a predetermined distance from the specific fire detection sensor. ) can be controlled to open.

That is, when only the fourth fire detection sensor 184 among the plurality of fire detection sensors 181-186 disposed on the wall detects a fire, the fourth fire detection sensor 184 and the fourth fire detection sensor 184 are arranged in pairs. In addition to the operation of the injection nozzle 164 , other injection nozzles located in the vicinity of the fourth injection nozzle 164 may also operate.

For example, the first injection nozzle 161 located above the fourth injection nozzle 164, the fifth injection nozzle 165 located on the right side of the fourth injection nozzle 164, and the fourth injection nozzle ( The second injection nozzles 162 positioned diagonally to the right of 164 may be opened together with the fourth injection nozzles 164 , respectively.

In addition, the control unit within the injection nozzle 160 so that a plurality of nozzle units 164 in each injection nozzle 160 located within a predetermined distance from the specific fire detection sensor are directed toward the location where the specific fire detection sensor is located. Each of the plurality of nozzle units 164 may be individually rotated at different rotation angles.

Hereinafter, with reference to FIG. 6, the state change of the injection nozzle according to the fire detection position will be described in detail.

6 is a view showing the rotational state of the injection nozzle according to the fire detection position.

As shown in FIG. 6 , the injection nozzle 160 includes a pipe coupling part 162 and a nozzle part 164 .

The pipe coupling part 162 has a cylindrical shape, and one end is coupled to the water supply pipe 120 .

The nozzle part 164 is connected to the other end of the pipe coupling part 162, is positioned to protrude from the pipe coupling part 162, and a plurality of nozzles 164 are individually rotated at different angles to spray water.

For example, in the case shown in FIG. 6A , all of the first to third nozzles 164a - 164c included in the nozzle unit 164 may spray water only toward the front. In addition, in the case shown in FIG. 6(b), when the fire detection area is larger than the preset reference area, the first to third nozzles 164a to 164c in the nozzle unit 164 are individually directed in different directions, respectively. can rotate That is, the first nozzle 164a is rotated by 30° from the pipe coupling part 162, the second nozzle 164b is rotated by 90° from the pipe coupling part 162, and the third nozzle 164c is It can rotate by 150° from the pipe coupling part 162 . In addition, as shown in FIG. 6C , the first to third nozzles 164a - 164c may be rotated to face a specific fire detection sensor 180 that detects the occurrence of a fire.

In addition, when each fire detection signal is received from a plurality of fire detection sensors 180 in different areas within the building, the control unit may transmit the fire detection signal to a nearby fire station. Therefore, in the case of detecting a relatively local fire at the beginning of the fire, rapid fire suppression can be performed through the wall panel sprinkler system of the present invention, and when a fire occurs in a relatively wide range, an external fire department is notified of the fire. In other words, firefighters can perform initial fire suppression more quickly before starting full-scale fire suppression.

The wall panel sprinkler system according to an embodiment of the present invention installs a fire detection sensor and a spray nozzle between sandwich panels installed on the wall of a building, so that even if the sprinkler installed on the ceiling does not operate normally, fire suppression can be quickly processed. have.

In addition, in the wall panel sprinkler system according to an embodiment of the present invention, when a fire occurs in a specific location or local area within a building, only a predetermined spray nozzle located in the vicinity of the place where the fire occurs among all the spray nozzles installed on the wall. By suppressing the fire by driving this, it is possible to minimize damage to property and property that is inevitably generated during fire suppression.

The above-described preferred embodiments of the present invention have been disclosed for the purpose of illustration, and those skilled in the art with ordinary knowledge for the present invention will be able to make various modifications, changes, and additions within the spirit and scope of the present invention, such modifications, changes and Additions should be considered to fall within the scope of the following claims.
