Description

Water screen system for blocking external fire

The present invention relates to a water film forming system for shielding surrounding fires, and more particularly, to a water film forming system for surrounding fire shielding to protect a building by efficiently blocking the surrounding fire while improving the utility of the space around the aesthetics and buildings. .

Generally, it is legal for fire-fighting facilities of fire-related laws and regulations that are currently applied to buildings to be equipped with fire-extinguishing facilities for fire suppression such as fire-fighting equipment, sprinkler equipment, spraying equipment or alarm equipment, depending on the size, .

All of these legal fire extinguishing facilities are being developed not only for self-evacuation when a fire occurs inside the building but also because the provisions of the statutory fire extinguishing equipment are also specified in order to focus on the self-fire evolution of the building. It is impossible to cope.

On the other hand, fire from the outside is largely a large fire, which can not be accessed even by fire hydrants used by people due to radiant heat or flames accompanied by headwinds. For this reason, buildings adjacent to mountainous areas and forests are burnt down due to forest fires, etc., and there are only cultural properties that can not be valued among them.

In addition, in the case of buildings located in forests and forest areas, there is a problem that it is difficult to enter fire trucks in case of a fire due to a lack of surrounding roads, and it takes a lot of time to arrive even though diversion is possible.

In view of this, a water film forming system for preventing a fire from a forest fire or an adjacent building from covering a building by forming a water film around a building to be protected is proposed as a registered patent No. 932232 (hereinafter referred to as 'prior art'). .

BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a schematic block diagram of a floor-mounted water film forming system according to the prior art; FIG. 1, according to a conventional water film forming system, a water tank 110 storing water is disposed next to a building, and a main pipe (not shown) for supplying water to be connected to the water tank 110 120 are installed. On the other hand, in the middle of the main pipe 120, a pipe switch 125 for regulating the flow of water is provided. Normally, water is prevented from flowing to the main pipe 120 while the pipe switch 125 is closed, So that the water flows along the main pipe 120 by opening the pipe switch 125.

A nozzle-side pipe 130 is installed on at least one edge of the building. The nozzle-side pipe 130 is embedded at a distance from the wall of the building. A plurality of inlet pipes 137 are provided at predetermined intervals in the thus installed nozzle side pipe 130 and an injection nozzle 135 is further provided at an upper portion of the inlet pipe 137.

The inlet piping 137 is designed to be installed vertically in the air from the ground or tilted at a certain 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 buried in the floor around the building, not only the construction cost is excessively increased but also the main piping 120 and the inlet piping 137 are exposed to the outside As a result, there was a problem of not only hindering the use of space such as accessing activities but also harming the beauty.

The inlet pipe 130 'includes a main pipe 120' having one end connected to the water or fire hydrant. .

In the above-described configuration, when water flow is allowed through the main pipe 120 'by automatic operation by sensor response or manual operation by a manager in the event of a fire, water that has passed through the main pipe 130' flows through the inlet pipe 130 ' And the nozzle side piping 137 ', and finally sprayed through the injection nozzle 135', thereby forming a water film in front of the wall of the building as shown by a dotted line.

However, according to the conventional rooftop installation water film forming system as described above, since the nozzle side piping protrudes from the wall of the building, there is a problem that the aesthetic appearance is severely damaged.

As a result, the hydraulic receiving plate 440 in the cylinder 4300, and consequently, the piston 435 and the nozzle pipe 450 integrally coupled thereto are moved upward, and the cover 410 is flipped upward by the force. The resulting spray nozzle 480 is exposed or protruding from the bottom.

In addition, the water introduced into the cylinder 430 flows into the nozzle pipe 450 through a gap between the cylinder 430 and the hydraulic receiving plate 440, and the water thus introduced passes through the L-shaped connecting pipe 470. The water is ejected upward through the spray nozzle 480 by being supplied to the spray nozzle 480.
