水幕形成裝置3包括形成水通路的管10、配置在管10的一端的接納接頭21、配置在管10的另一端的插入接頭22、以及使在管10內流動的滅火水噴出的噴嘴部30。 在水幕形成裝置3中，在接納接頭21結合有第一消防水帶2a(參照圖1)的插入接頭，在插入接頭22結合有第二消防水帶2b(參照圖1)的接納接頭，利用從噴嘴部30噴出的滅火水將火花熄滅。 噴嘴部30形成有噴出口31。 管10和噴嘴部30由殼體40覆蓋，在殼體40設置有重量部41，在設置時噴出口31處於朝向鉛直上方的位置。藉由設置重量部41，能夠迅速地進行使用時的設置作業。The water curtain forming device 3 includes a tube 10 that forms a water passage, a receiving joint 21 disposed at one end of the tube 10, an insertion joint 22 disposed at the other end of the tube 10, and a nozzle portion that ejects the extinguishing water flowing in the tube 10 30.

噴嘴部30具有在一端有形成噴出口31的第一噴嘴通路32、和與第一噴嘴通路32的另一端連接的第二噴嘴通路33。 噴出口31形成在從噴嘴部30的端部30a凹陷的位置。像這樣地藉由使噴出口31形成在從端部30a凹陷的位置，能夠防止使用時損傷到噴出口31，因此能夠防止由於損傷導致水柱斷裂。 第一噴嘴通路32形成為內徑恆定的筒狀，第二噴嘴通路33形成為錐形狀，使內徑從上游朝向下游側逐漸縮小。 較佳的是，第二噴嘴通路33的錐形角度α介於15°以上45°以下的範圍。 這樣，藉由在筒狀的第一噴嘴通路32的上游形成錐形狀的第二噴嘴通路33，能夠朝向噴出口31提高壓力，並且產生整流效果，因此，能夠將從噴嘴部30噴出的滅火水所產生的水柱形成至較高的位置，並且在較高的位置形成水幕。The nozzle section 30 has a first nozzle passage 32 forming a discharge port 31 at one end, and a second nozzle passage 33 connected to the other end of the first nozzle passage 32. The ejection port 31 is formed at a position recessed from the end 30 a of the nozzle part 30. In this way, by forming the discharge port 31 at a position recessed from the end portion 30a, it is possible to prevent damage to the discharge port 31 during use, and thus it is possible to prevent the water column from being broken due to the damage. The first nozzle passage 32 is formed in a cylindrical shape with a constant inner diameter, and the second nozzle passage 33 is formed in a tapered shape so that the inner diameter gradually decreases from upstream to downstream. Preferably, the taper angle α of the second nozzle passage 33 is in the range of 15° or more and 45° or less. In this way, by forming the tapered second nozzle passage 33 upstream of the cylindrical first nozzle passage 32, the pressure can be increased toward the discharge port 31 and a rectifying effect can be produced, so the fire extinguishing water sprayed from the nozzle section 30 can be produced The generated water column is formed to a higher position, and a water curtain is formed at the higher position.

將管10內的滅火水引導至第二噴嘴通路33的導出部50的內徑設為第二噴嘴通路33的上游側內徑以上。藉由具備這樣的導出部50，進一步產生整流效果，因此能夠進一步將水柱形成至較高的位置。此外，也可以不具備導出部50，而是使第二噴嘴通路33的上游側突出到管10內。The inner diameter of the lead-out portion 50 that guides the fire fighting water in the tube 10 to the second nozzle passage 33 is equal to or greater than the upstream inner diameter of the second nozzle passage 33. By providing such a lead-out portion 50, a rectifying effect is further generated, so that the water column can be further formed to a higher position. In addition, the lead-out portion 50 may not be provided, but the upstream side of the second nozzle passage 33 may protrude into the tube 10.

在導出部50設置有整流部件60。使複數片整流板61放射狀地安裝於軸部62，從而形成整流部件60。滅火水在整流板61之間沿著軸部62的方向流動。軸部62的兩端比整流板61突出，並具有前端變細的形狀。藉由這樣將整流部件60配置在導出部50，進一步產生整流效果，進而能夠將水柱形成至較高的位置。The lead-out unit 50 is provided with a rectifying member 60. A plurality of rectifying plates 61 are radially attached to the shaft portion 62 to form a rectifying member 60. The fire extinguishing water flows in the direction of the shaft portion 62 between the flow straightening plates 61. Both ends of the shaft portion 62 protrude from the rectifying plate 61 and have a tapered shape at the front end. By arranging the rectifying member 60 in the lead-out portion 50 in this way, a rectifying effect is further produced, and the water column can be formed to a higher position.

在本實施例中，作為噴嘴部30，具有第一噴嘴部30A和第二噴嘴部30B。像本實施例這樣，在由第一噴嘴部30A和第二噴嘴部30B構成噴嘴部30的情況下，較佳的是，第一噴嘴部30A的第一假想軸線30X與第二噴嘴部30B的第二假想軸線30Y之間的角度β介於15°以上20°以下的範圍。藉由這樣由第一噴嘴部30A和第二噴嘴部30B構成噴嘴部30，並使第一假想軸線30X與第二假想軸線30Y之間的角度β介於15°以上20°以下的範圍，能夠將水柱形成至較高的位置，並且能夠提高水幕的形成效果。 此外，作為噴嘴部30，可以進一步設置第三噴嘴部。在進一步設置第三噴嘴部的情況下較佳的是，藉由使第三噴嘴部的第三假想軸線與導出部50的假想軸線一致，使得第三噴嘴部的噴出口朝向鉛直上方。In this embodiment, as the nozzle portion 30, there are a first nozzle portion 30A and a second nozzle portion 30B. Like this embodiment, when the nozzle part 30 is constituted by the first nozzle part 30A and the second nozzle part 30B, it is preferable that the first virtual axis 30X of the first nozzle part 30A and the second nozzle part 30B The angle β between the second virtual axis 30Y is in the range of 15° or more and 20° or less. By configuring the nozzle portion 30 by the first nozzle portion 30A and the second nozzle portion 30B in this way, and making the angle β between the first virtual axis 30X and the second virtual axis 30Y between 15° and 20°, it is possible to The water column is formed to a higher position, and the formation effect of the water curtain can be improved. In addition, as the nozzle portion 30, a third nozzle portion may be further provided. When the third nozzle portion is further provided, it is preferable that the third virtual axis of the third nozzle portion and the virtual axis of the lead-out portion 50 coincide so that the discharge port of the third nozzle portion faces vertically upward.

較佳的是，如圖2(b)和2(c)所示，導出部50的上游側端部51比管10的內周面突出。藉由使導出部50的上游側端部51比管10的內周面突出，能夠改變在管10內流動的滅火水的流動，減小管10內部的流速的影響，提高導出部50的壓力，從而能夠確保水柱高度，並且如圖1所示，在將多個水幕形成裝置3與消防水帶2串聯連接來使用的情況下，能夠使各個水幕形成裝置3中的水柱高度均勻。 此外較佳的是，上游側端部51突出在未到達管10的管假想軸線10X的範圍內。藉由使上游側端部51突出在未到達管假想軸線10X的範圍內，來減少管10內的壓力損失，特別是在將多個水幕形成裝置3與消防水帶2串聯連接來使用的情況下，也能夠防止由於壓力損失導致的水柱高度的降低。Preferably, as shown in FIGS. 2( b) and 2 (c ), the upstream end 51 of the lead-out portion 50 protrudes beyond the inner circumferential surface of the tube 10. By making the upstream end 51 of the lead-out portion 50 protrude from the inner peripheral surface of the tube 10, the flow of fire-extinguishing water flowing in the tube 10 can be changed, the influence of the flow velocity inside the tube 10 can be reduced, and the pressure of the lead-out portion 50 can be increased Thus, the height of the water column can be ensured, and as shown in FIG. 1, when a plurality of water curtain forming devices 3 and the fire hose 2 are connected in series and used, the height of the water column in each water curtain forming device 3 can be made uniform. In addition, it is preferable that the upstream end portion 51 protrudes within the range of the tube virtual axis 10X that does not reach the tube 10. Reduce the pressure loss in the tube 10 by protruding the upstream end 51 within the range that does not reach the imaginary axis 10X of the tube, especially when the multiple water curtain forming devices 3 and the fire hose 2 are connected in series In this case, it is also possible to prevent a decrease in the height of the water column due to pressure loss.
