<P>PROBLEM TO BE SOLVED: To provide a water discharge nozzle device for fire extinguishing which includes an angle adjustment device which can fix angles of two or more movable draining water pipes, changes the angles of the movable draining water pipes and can change an extinction area to an extinction object, changes the angle while draining water, and thereby can extinguish corresponding to a situation. <P>SOLUTION: The following means are adopted for the water discharge nozzle device for fire extinguishing 1. First, a single large diameter receiving hole 7 is bored in a water supply side, two or more small diameter branch through-holes 8 are bored in a draining water side to be consecutive with the receiving hole 7, a branch fitting 4 in which immovable branch pipes 3 having angles each opening together are disposed to continue at distal ends of the two or more branch through-holes 8 toward the draining water side is included. Second, movable draining water pipes 5 having a discharge port 13 connected at distal ends of the immovable branch pipes 3 to freely turn are included. Third, an angle adjusting device 6 which can change or fix angles of two or more drain water pipes 5 to an opening direction or a settling direction is included, and the desired angles are set to be fixed. <P>COPYRIGHT: (C)2012,JPO&INPIT |
