It can be wired or wirelessly connected to transmit.

The power control module 410 is electrically connected to the rainfall pump 500 and may operate by receiving an operation command from the central control unit 100. When a fire occurs, the central control unit 100 operates the power control module 410 so that the rainfall pump 500 and the injection unit 600 operate by the power control module 410 to extinguish the fire.

The external power supply units 420 and 400 are electrically connected to the power control module 410 and may receive commercial power from a commercial power plant to supply power necessary for the cultural property 10 and the firefighting system. That is, the external power supply units 420 and 400 may supply power to the cultural property 10 during normal times when no fire occurs.

When a fire occurs, the external power supply units 420 and 400 may still supply power to the cultural property 10 and the fire fighting system. However, in the event of a fire, the external power supply units 420 and 400 may not be able to supply power to the fire fighting system due to loss of power lines or other power supply devices or interruption of external commercial power supply due to emergency measures.

Accordingly, in order to supply power for operation to the fire fighting system when the power supply from the external power supply units 420 and 400 is cut off when a fire occurs, the emergency power generation device 430 may be provided in the embodiment.

The emergency power generation device 430 is electrically connected to the power control module 410, receives an operation command from the power control module 410, operates, and generates emergency power to be supplied to the fire fighting system.

When a fire occurs, the power control module 410 is operated, and the power control module 410 is supplied from the external power supply unit 420, 400 when the power supply to the fire fighting system is maintained from the external power supply unit 420, 400. The input commercial power may be supplied to the rainfall pump 500 and an operation command may be transmitted to the rainfall pump 500.

When the power supply to the firefighting system is cut off from the external power supply unit 420, 400 when a fire occurs, the power control module 410 transmits an operation command to the emergency power generation device 430, and the rainfall pump 500 It can supply power to and transmit operation commands.

With reference to FIG. 1 again, the rainfall pump 500 and the injection unit 600 will be described in detail.

The rainfall pump 500 may operate by receiving power from the power supply units 420 and 400. As described above, the power supply units 420 and 400 may supply power to the rainfall pump 500 and transmit an operation command at the same time.

When a fire occurs, the rainfall pump 500 may operate to pump water for fire fighting to the injection unit 600. Accordingly, the rainfall pump 500 may be connected to one side by a water supply means (not shown) for firefighting and the other side by the injection unit 600 and a pipe, respectively.

The injection unit 600 is connected to the rainfall pump 500 and installed underground, and is elevated to the ground in case of a fire, and sprays water for firefighting to the cultural property through the spray nozzle 600a in the form of rainfall, and the first injection nozzle 610 and a second injection nozzle 620 may be included. The first injection nozzle 610 and the second injection nozzle 620 may be provided in plural in the cultural property 10. At this time, the number and arrangement position of each of the first injection nozzle 610 and the second injection nozzle 620 may be appropriately selected according to the size, structure, and degree of fire vulnerability of the cultural property 10.

The first injection nozzle 610 may be provided so that the sprayed water has a linear stream line. The second injection nozzle 620 may be provided so that the sprayed water forms a film made of mist.

The first injection nozzle 610 allows water to have a linear streamline, so that the sprayed water applies a strong hydraulic pressure to the fire vulnerable part 11 and a large amount of water is intensively applied to the fire vulnerable part 11. I can. As a result, the sprayed water may extinguish a fire occurring in the vulnerable part 11 early, or sufficient water may be sprayed into the vulnerable part 11 that has not yet been lit, so that the flame may not be transferred there.

The second spray nozzle 620 allows the sprayed water to form a film made of mist, so that the entire cultural property 10 may be covered with a mist film. A mist membrane covers the cultural property 10 and separates the fired cultural property 10 from other structures, forests, etc., so that the fire does not move from the fired cultural property 10 to other structures or forests. Of course, water sprayed from the second spray nozzle 620 to form a mist film may directly extinguish the fire.

3 is a view for explaining the arrangement of the injection unit 600 according to an embodiment. In FIG. 3, the cultural property 10 is, for example, a collection of wooden structures located adjacent to a forest. Therefore, each of the wooden structures arranged at intervals from each other in the cultural property 10 is a fire vulnerable part 11 that is easily transferred, combustion proceeds quickly, and the fire is difficult to extinguish.

The first injection nozzle 610 and the second injection nozzle 620 may be disposed in an appropriate number inside or outside the cultural heritage 10 in an appropriate number.

It is protected and can be provided in a variety of other ways, such as buried underground, where the hangar is opened during operation and the nozzle rises to the ground.

The first injection nozzle 610 directs the water outlet to each of the fire-vulnerable parts 11, and may be arranged in an appropriate number at an appropriate position. Accordingly, water having a linear streamline sprayed from the first injection nozzle 610 applies strong hydraulic pressure to each of the fire vulnerable parts 11 to extinguish a fire early.

In addition, even when the fire-vulnerable part 11 has not yet been set on fire, sufficient water has been sprayed from the first injection nozzle 610, so that the fire cannot be transferred to the fire-vulnerable part 11 from other places. .

A plurality of second injection nozzles 620 may be provided in an appropriate number at an appropriate location inside or adjacent to the cultural property 10 so as to surround the entire cultural property 10 including the plurality of fire vulnerable parts 11 I can.

The water discharge port of the second injection nozzle 620 faces in the direction covering the cultural property 10, and the cross-sectional shape of the discharge port of the second injection nozzle 620 and the discharge water pressure are appropriately adjusted, so that the second injection nozzle Water sprayed from 620 may be formed to form a mist film as a whole.

In the event of a fire, the mist film formed by the water sprayed from the plurality of second spray nozzles 620 covers the entire cultural property 10, thus effectively suppressing the fire from moving to the cultural property 10 from the outside and causing the fire to volcano, In addition, it is possible to effectively suppress the spread of fire by transferring fire to an external forest or other building as the cultural property 10.

4 is a view for explaining a state in which the injection unit 600 of the rain spray system for preventing fire from a cultural property according to an embodiment is operated.

As shown in Figure 4, the spraying part 600, the spray nozzle (600a) protruding to the ground is tilted up and down with respect to the ground, or rotated in the left and right direction to rain water on the cultural property 10 Can be sprayed.

The injection part 600 is installed underground rather than above ground in consideration of the appearance of the cultural property 10. When a fire is detected by the sensor module 200 during a fire of the cultural property 10, the injection part 600 in the basement rises to the ground. At this time, the cover 600b covering the spray part 600 on the ground is automatically opened for 3 to 5 seconds. At the same time, the rainfall pump 500 is operated so that the injection nozzle 600a of the injection unit 600 sprays water in the form of rainfall.

The rainfall pump 500 may be automatically converted into an emergency generator system when the power is automatically turned off and operated by receiving power. In the event of a fire, only the storm injection system can be powered.

In addition, the injection nozzle 600a protrudes to the ground while pushing up the cover 600b with the elevation of the injection unit 600. Since the spray nozzle 600a can be remotely controlled by an operator while looking at the monitor, rain can be sprayed toward the cultural property 10 in the vertical direction or the left and right directions. When the sensor module 200 detects a fire, the spray nozzle 600a operates within 30 seconds to rapidly spray water.

In the case of a fire of the cultural property fire prevention rainfall spraying system of the embodiment, the rain spraying system in the event of a fire of the cultural property 10 supplies moisture to the wood of the wooden structure in an instant by intensive rainfall to continuously form a water film around the cultural property 10. It can block the spread of fire.

The cultural property fire prevention rainfall injection system of the embodiment can quickly and quickly extinguish the fire of the cultural property 10 located in a place where firefighting equipment and firefighting personnel are difficult to quickly enter the mountain and other road conditions.

The fire prevention rainfall injection system for cultural properties of the embodiment is an unmanned automated system, so resident personnel are not required, and thus it is very advantageous in cost reduction.

As described above with respect to the embodiment, only a few are described, but other various types of implementation are possible. The technical contents of the above-described embodiments may be combined in various forms, unless they are technologies incompatible with each other, and may be implemented as a new embodiment through this.
