Description

The present invention relates to a fire spread prevention system, and more particularly to a fire spread prevention system suitable for a densely wooded area.

Traditionally, there are areas where wooden buildings are densely built (wooden areas). In this densely wooded area, the distance between adjacent buildings is very narrow along with the characteristics of the material of wood, so if a fire breaks out in a building in that area, the surrounding buildings will also be affected. There is a problem that the fire spreads easily.

Also, in densely wooded areas, the width of the alleys is narrow, so it may be difficult for relatively large vehicles such as fire engines to enter the vicinity of the fire site, and fire extinguishing activities are efficient. It may not be possible to do it. This is also a factor that makes it easy for fire to spread to surrounding buildings.

For example, in the fire extinguishing equipment of Patent Document 1, a sprinkler facility is provided in each building, the sprinkler facility is connected to a pipe stretched around the area where the building is located, and a water supply port capable of supplying water to the pipe from the outside is provided. By installing it on a relatively wide road where large vehicles can pass, it is possible to sprinkle fire extinguishing water on the fire site and extinguish the fire even if fire fighting vehicles cannot enter the vicinity of the fire site. There is.

Naturally, the flames that cause the spread of fire in a building come from outside the building. Depending on the conditions such as the wind direction, the fire may spread not only in the section where the building is the source of the fire, but also in the adjacent section separated by the alley or in the further separated section, and even develop into a larger-scale fire. ..

Conventional fire extinguishing equipment is intended to extinguish a fire inside a building, not to prevent the spread of fire in the building itself. It was installed inside the building, and it was difficult to deal with flames and fires coming from outside the building. Therefore, conventional fire extinguishing equipment is excellent in that it extinguishes the fire source or the building that has already spread, and stops the further spread of fire, but it is the building around the building where the fire broke out. It was inadequate in terms of preventing the spread of fire itself.

Therefore, an object of the present invention is to provide a fire spread prevention system suitable for a densely wooded area in view of the actual situation of such a densely wooded area.

It is a schematic diagram which shows the embodiment of this invention. It is a figure which shows the embodiment of this invention, (a) is a schematic diagram of a densely wooded area, (b) is an enlarged view of the main part of (a).

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. The fire spread prevention system 1 is installed in a densely wooded area 2 and includes a pipe 10, a drainer head 11, and a water supply port 12.

For example, the densely wooded area 2 is composed of a plurality of sections 21 separated by an alley 20, and each section 21 is densely provided with wooden buildings 22 such as houses. In such a densely wooded area 2, in many cases, the alley 20 has a road width that makes it difficult for relatively large vehicles such as a fire engine 3 to pass through, and one person is between the adjacent buildings 22 and 22. It is a distance that is difficult to pass through.

The pipe 10 is stretched between the building 22 and the building 22 so as to surround the building 22. At the base end (upstream side end) 10a of the pipe 10, a water supply port 12 which is an example of a water supply means for supplying water to the pipe 10 is provided. Further, a drain valve 13 for draining the residual water in the pipe 10 is provided at the tip end (downstream side end) 10b of the pipe 10. The position where the pipe 10 is installed can be appropriately selected as needed, but in the present embodiment, the pipe 10 is stretched so as to crawl along the ground 4.

In the present embodiment, the water supply port 12 is provided so that the hose of the fire engine 3 can be connected via, for example, a connection fitting, and the fire extinguishing water from the fire engine 3 is supplied into the pipe 10 via the hose. It is possible. The water supply port 12 is provided at a position where the hose reaches from a road 5 having a road width at least through which a fire engine 3 can pass, and is preferably provided on the road 5 or facing the road 5. If it is within the length of the hose, the water supply port 12 may be provided in the alley 20 deep from the road 5.

The drainer head 11 is connected to the pipe 10. When a fire breaks out in the densely wooded area 2, the drainer head 11 discharges the water in the pipe 10 supplied from the water supply port 12 to form a curtain-shaped water curtain W between the buildings 22 and 22. , The fire spread of the building 22 is prevented by discharging water to the building 22. The installation position of the drainer head 11, the water discharge pattern, and the like can be appropriately adopted as needed, and for example, the following can be adopted.

(A) The drainer head 11A is provided between the buildings 22 and 22 so as to be connected to the downstream end of the side pipe 14A extending substantially vertically from the pipe 10. The drainer head 11A can form a water curtain WA by discharging curtain _- shaped water upward. The drainer head 11A separates the buildings 22 and 22 by a water curtain _WA , so that it is possible to prevent the fire from spreading from the building 22A where the fire has already occurred to the adjacent building 22. At this time, it is preferable that the height of the water curtain _WA is discharged to a position higher than that of the roof 22a.

(B) The drainer head 11B is connected to the downstream end of the side pipe 14B extending substantially vertically from the pipe 10 to the height of the roof 22a of the building 22, for example, the eaves 22b of the roof 22a or its vicinity. It is provided in the vicinity of the roof 22a between the building 22 and the building 22. The drainer head _11B forms a substantially fan-shaped water curtain WB by discharging the curtain-shaped water, whereby water can be discharged to the roofs 22a and 22a, and the adjacent buildings 22 and 22 can be discharged. By covering the roofs 22a and 22a with the water curtain _WB , it is possible to prevent the building 22 from spreading due to a jumping fire from the building 22A where the fire is occurring.

(C) The drainer head 11C is connected to the downstream end of the side pipe 14C extending from the pipe 10 along the building 22 to the roof 22a or its vicinity, for example, the ridge 22c or its vicinity. It is provided in or near the roof 22a, and it is possible to discharge curtain-shaped water to the roof 22a to form a substantially arc-shaped water curtain _WC , whereby the roof 22a is formed into a water curtain _WC . It is designed to be covered with. In the present embodiment, the side pipe 14C extends from under the eaves of the roof 22a through the inside of the roof 22a to the vicinity of the ridge 22c. Thereby, the drainer head 11C makes it possible to prevent the building 22 from spreading due to the jumping fire from the building 22A where the fire is occurring. The side pipe 14C may be provided outside the roof.

(D) The drainer head 11D is provided at or near the roof 22a so as to be connected to the downstream end of the side pipe 14D similar to the side pipe 14C, and is provided along the roof 22a with respect to the roof 22a. It is possible to discharge curtain-shaped water. As a result, the drainer head _11D can form a water curtain WD so as to cover the roof 22a, and prevent the building 22 from spreading due to a fire from the building 22A where the fire is occurring. It is possible to do.

(E) The drainer head 11E is provided in or near the roof 22a so as to be connected to the downstream end of the side pipe 14E similar to the side pipe 14B, and is provided along the roof 22a with respect to the roof 22a. It is possible to discharge the curtain-shaped water. As a result, the drainer head 11E can form a water curtain _WE so as to cover the roof 22a, and prevent the building 22 from spreading due to a fire from the building 22A where the fire is occurring. It is possible to do.

The drainer heads 11 are installed at intervals at which the water curtain W can be stretched as closely as possible, for example, at substantially equal intervals along the sides of the building 22. At this time, the same type of drainer head 11 may be installed, or a plurality of types of drainer heads 11, for example, the drainer head 11A and the roof _22a forming a water curtain WA between the buildings 22 and 22. It is also possible to install the drainer heads 11B, 11C, _11D , 11E forming the water curtains _WB , _WC , WD, and _WE in combination.

When a fire breaks out in a building 22 with a wooded area 2, for example, building 22A, the hose of the fire engine 3 arriving at the wooded area 2 is connected to the water supply port 12 by a report or the like, and the fire engine 3 is connected. The fire extinguishing water is supplied into the pipe 10 through the water supply port 12. Then, the fire spread prevention system 1 starts water discharge from each drainer head 11 sequentially to the buildings 22 and 22 and the roof 22a, and discharges water in a curtain shape to form a water curtain W. Since the water curtain W prevents flames and jumping fires, it prevents the spread of fire from the building 22A to other buildings 22.

Even in a densely wooded area 2 where it is difficult for the fire engine 3 and the like to enter the fire site because the alley 20 is narrow because the water outlet 12 is provided at least within the range where the hose of the fire engine 3 can reach from the road 5. It is possible to prevent the spread of fire.

Although the present invention has been described above based on the above embodiment, the present invention is not limited to the above embodiment and can be appropriately modified without changing the gist of the invention.

For example, (1) instead of supplying water from the fire truck 3 into the pipe 10, water in a fire hydrant, a water tank, a reservoir, a lake, a river, the sea, etc. is pumped by a pump or the like, and water is supplied from the water supply port 12 into the pipe 10. It is also possible to do so.

(2) The pipe 10 may be installed at a position higher than the ground 4, for example, at a height of the eaves 22b, the ridge 22c, or higher. A pipe 10 may be provided at the height of the eaves 22b, and the pipe 10 may be provided with a drainer head that discharges water upward and a drainer head that discharges water downward.

(3) The side pipe 14A is extended like the side pipes 14B and 14E, the drainer head 11A is connected to the side pipe 14A downward, water is discharged downward from the drainer head 11A, and the water curtain W is used. _A may be formed between the buildings 22 and 22.

(4) If there is a margin in the water pressure and the amount of water in the pipe 10, the drainer head 11 may discharge water in a plurality of directions. For example, the drainer head _11B can further form a water curtain (not shown) such as a water curtain WA, and a water curtain _WB is formed with respect to the roof 22a of the building 22 and the building. It is also possible to form a water curtain between 22 and 22.

(5) It is also possible to shorten the side pipe 14B like the side pipe 14A and use the drainer head 11B to discharge water to the walls of adjacent buildings 22 and 22.

(6) Even if the pipe 10 is connected to a water supply means in the building 22 such as a public water supply, the fire spread of the building 22 is prevented for the time being until the fire engine 3 arrives at the wooded area 2. good.

(7) The fire spread prevention system 1 covers the entire building 22 with a water curtain W and prevents the fire from spreading due to a fire from the outside. However, due to the influence of the wind, the fire ignites the roof 22a and spreads. In many cases, the height of the water curtain W spouted from the ground is preferably equal to or higher than the height of the roof 22a. In particular, in the densely wooded area 2 where the buildings 22 are densely packed, it is possible to prevent the roof 22a from being ignited by a jumping fire by discharging only the upper side of the roof 22a above the eaves 22b in a water curtain shape, and a thatched roof or the like is used. It is a suitable system for the building 22.

(8) Although the pipes 10 are arranged so as to be stretched around each building, a plurality of densely packed buildings may be grouped together and the pipes 10 may be stretched in units of 21 sections.
