Description

Fire protection system

The present invention relates to a fire protection system, and in particular, to suppress forest fires in forest areas and secondaryly to extinguish fires around buildings. It relates to one fire protection system.

In general, it is legal for firefighting facilities of fire-fighting laws to be applied to the current building according to the size, use and capacity of the building to have fire extinguishing facilities for fire extinguishing such as fire hydrant, sprinkler, sprinkler or alarm. Is required.

All of these legal fire extinguishing facilities are being developed for self-extinguishing when a fire breaks out inside the building, and the statutory fire extinguishing system also focuses on the fire extinguishing of the building itself. It is impossible to cope.

On the other hand, most of the fire from the outside is a large-scale fire, and most people cannot respond to the fire hydrant used by humans due to radiant heat or a flame accompanied by a wind. For this reason, there are cases in which buildings adjacent to mountain areas or forests are burned down by forest fires at home and abroad, and there is only one cultural property whose value cannot be calculated.

In addition, in the case of buildings in forests and forest areas, it is difficult to enter fire trucks in case of fire due to inadequate road network, and even if it is possible to dispatch, even if it takes a long time to arrive, there is a problem in that it cannot cope quickly in a timely manner.

In view of this, a water film forming system is proposed in Korean Patent No. 932322 (hereinafter referred to as 'prior art') to form a water film around a building to be protected, thereby preventing a fire from a forest fire or an adjacent building from covering the building. .

1 is a schematic configuration diagram of a water film forming system for floor installation according to the prior art. As shown in FIG. 1, according to the conventional water film forming system, a water tank 110 storing water is disposed next to a building, and a main pipe supplying water to be connected to the water tank 110 ( 120) is installed. Meanwhile, in the middle of the main pipe 120, a pipe switch 125 is installed to control the flow of water. In the case of a fire, the water is blocked in the main pipe 120 while the pipe switch 125 is closed. The water flows along the main pipe 120 by opening the pipe switch 125.

And the nozzle side pipe 130 is installed on at least one side edge of the building, the nozzle side pipe 130 is embedded at a certain distance away from the wall of the building. A plurality of inlet pipes 137 are installed in the nozzle side pipe 130 is installed at a predetermined interval, the injection nozzle 135 is again installed on the top of the inlet pipe 137.

Inlet pipe 137 is designed to be installed in the vertical direction from the ground to the air or inclined at an angle toward the building.

However, according to the conventional water film forming system as described above, since the nozzle-side piping and the like must be embedded on the floor around the building, the construction cost is excessively increased, and the main pipe 120 or the inlet pipe 137 is exposed to the outside. Therefore, there is a problem that not only hinders the use of space such as entrance and exit, but also hurts aesthetics.

2 is a schematic configuration diagram of a conventional water film forming system for rooftop installation. As shown in FIG. 2, the conventional water film forming system for rooftop installation includes an inlet pipe 130 ′ and an inlet pipe 130 ′ installed in parallel with an upper edge on a roof at a position adjacent to an upper edge of a corresponding wall of a building (BDG). A plurality of nozzle side pipes 137 'branched from the incoming pipe 130' at intervals so as to be in communication with each other, protruding about 30 to 60 cm out of the corresponding wall of the building BDG, with their free ends facing downward; And a spray nozzle 135 'installed at the free end of each nozzle side pipe 137'. The inlet pipe 130 'is connected to one end of the main pipe 120' for water or fire hydrant. Communicating with

In the above-described configuration, when water flows through the main pipe 120 'by the automatic operation by the sensor response or the manual operation by the manager in the event of fire, the water passing through the main pipe 130' is introduced into the incoming pipe 130 '. ) And the nozzle side pipe (137 ') is finally sprayed through the injection nozzle 135' to form a water film in front of the wall of the building as shown by the dotted line.

However, according to the conventional rooftop water film forming system as described above, since the nozzle-side piping is protruded from the wall of the building, there is a problem that seriously hurt the appearance. Furthermore, when the conventional spray nozzle is adopted, there is a problem in that a relatively large number of nozzle-side pipes and spray nozzles must be installed because the spreading range (angle) of the water sprayed through the spray nozzle is limited.

Above all, according to the conventional water film forming system as shown in Figs. 1 and 2, since the fire only operates after the fire reaches the periphery of the building, there is a problem in that it is difficult to effectively block the already large fires. .

The present invention has been made to solve the above-mentioned problems, and when not in use, retreating without being protruded from the wall surface or the floor surface of the building roof and protrudes from the wall surface or the floor surface of the building roof only when used and The purpose of the present invention is to provide a fire protection system that can protect the building by effectively blocking the surrounding fire while improving the utility of the aesthetics or the space around the building by forming a water screen for surrounding fire blocking at a distance.

According to the fire protection system of the present invention, when not in use, the retracted state does not protrude from the wall of the building roof or the floor around the building and then protrudes from the wall of the building roof or the floor around the building only to be used at a distance from the building wall. By forming a water barrier for the surrounding fire, it is possible to protect the building by effectively blocking the surrounding fire while improving the utilization of the aesthetics and the space around the building.

Furthermore, by operating in the early stages of forest fires, it is possible to prevent forest fires from spreading or spreading wild fires in the early stages of fire, and secondly, by operating the water film forming system around buildings when forest fires reach surrounding buildings to be protected. Fire can be blocked more efficiently.
