         [0026]    The sprinkling head body  10  is made by molding a metal material and is a tube of a circular shape or a polygon shape. A passage  11  is formed in the sprinkling head body  10 . An inlet  12  for fluidly connecting to the passage  11  is formed at one side of the sprinkling head body  10 . The sprinkling head body  10  is fluidly connected to the fire water supply pipeline  70  through the inlet  12  so that the water in the fire water supply pipeline  70  passes through the inlet  12  and enters into the passage  11 . The term of “water” is referred to the fire protection water or the fire protection foam. 
         [0027]    In one embodiment of the present invention, at a top of it a top layer draining interface  13  and at a bottom of it a bottom layer draining interface  14  are formed on the sprinkling head body  10 . A middle layer draining interface  15  is formed between the top layer draining interface  13  and the bottom layer draining interface  14  on the sprinkling head body  10 . The middle layer draining interface  15  is located near the inlet  12 . The water moving in the passage  11  can pass through the top layer draining interface  13 , the bottom layer draining interface  14  and the middle layer draining interface  15  to spray out. Furthermore, the top layer draining interface  13  and the middle layer draining interface  15  are respectively disposed in the radial direction of the sprinkling head body  10 . The bottom layer draining interface  14  is disposed in the axial direction of the sprinkling head body  10 . 
         [0028]    A long range sprinkler head  20  made by molding a metal for guiding a spraying direction of the water in the passage  11  to spray out is fixed and assembled by a screw at the top layer draining interface  13 . Furthermore, a long range outlet  21  for fluidly connecting to the passage  11  is formed at an end of the long range sprinkler head  20 . A first spoiler  23  is formed and extends from the long range sprinkler head  20 . In implementation, the first spoiler  23  for guiding a spraying direction of water emitted from the long range outlet  21  to spray in a long range sprinkling direction  211  extends obliquely from a lateral side of the long range outlet  21  to a front end of the long range outlet  21 . 
         [0029]    A short range sprinkler head  30  made by molding a metal for guiding a spraying direction of the water in the passage  11  to spray out is fixed and assembled by a screw at the bottom layer draining interface  14 . Furthermore, a short range outlet  31  for fluidly connecting to the passage  11  is formed at an end of the short range sprinkler head  30 . 
         [0030]    short range sprinkling direction  311  is formed from the short range outlet  31  and extends along its centerline. The water in the passage  11  moves through the short range outlet  31  to spray out in the short range sprinkling direction  311 . 
         [0031]    In real implementation, a tube-shaped nozzle  33  is assembled by a screw in the short range sprinkler head  30 . One end of the nozzle  33  extends to an outside of the short range sprinkler head  30 . The short range outlet  31  is formed at the nozzle  33 . In more details, a plurality of passing holes  331  are formed on an outer wall of the nozzle  33 . A ring-shaped channel  332  is formed between the outer wall of nozzle  33  and an inner wall of the short range sprinkler head  30 . When the water in the passage  11  enters into the short range sprinkler head  30 , the water sprays out from the short range outlet  31  and enters into the channel  332  via the passing holes  331 . Thus, the water moves through the channel  332  to spray out in an irradiating way so as to increase the coverage range during spraying from the short range sprinkler head  30 . 
         [0032]    A middle range sprinkler head  40  made by molding a metal for guiding a spraying direction of the water in the passage  11  to spray out is fixed and assembled by a screw at the middle layer draining interface  15 . Furthermore, a middle range outlet  41  for fluidly connecting to the passage  11  is formed at an end of the middle range sprinkler head  40 . A second spoiler  43  is formed and extends from the middle range sprinkler head  40 . In implementation, the second spoiler  43  for guiding a spraying direction of water emitted. from the middle range outlet  41  to spray in a middle range sprinkling direction  411  extends obliquely from a lateral side of the middle range outlet  41  to a front end of the middle range outlet  41 . 
         [0033]    Please refer to Figs. I and  2  demonstrating the pipe joint  50  is a bending pipe. A first mouth of pipe  51  and a second mouth of pipe  52  are respectively formed at both ends of the pipe joint  50 . In more details, the pipe joint  50  is bending at a right angle so that the directions of the first mouth of pipe  51  and the second mouth of pipe  52  are perpendicular to each other. Furthermore, the pipe joint  50  is fluidly connected to an inlet  12  of the sprinkling head body  10  via the first mouth of pipe  51  and is fluidly connected to the fire water supply pipeline  70  via the second mouth of pipe  52  so that the water in the fire water supply pipeline  70  flows through the pipe joint  50  and enter into the passage  11  in the sprinkling head body  10 . 
         [0034]    Please refer to  FIGS. 1 and 3  demonstrating the level-meter  60  can be a circular bubble-type level-meter. In implementation, the level-meter  60  is secured to the sprinkling head body  10 . In more details, a flat surface  16  is formed at top of the sprinkling head body  10 . The level-meter  60  is fixed to the flat surface  16 . Furthermore, the flat surface  16  can provide a horizon reference surface  61 . When the bubble in the level-meter  60  is located in the middle of the level-meter  60 , the horizon reference surface  61  of the level-meter  60  is parallel to the level line of the ground surface. 
         [0035]    Please refer to  FIGS. 2 and 3  demonstrating when the pipe joint  50  is bending at a right angle, the pipe joint  50  comprises a first rotary connecting center line  511  and a second rotary connecting center line  521  which are perpendicular to each other. The first rotary connecting center line  511  and the second rotary connecting center line  521  are respectively formed at the first mouth of pipe  51  and at the second mouth of pipe  52 . In one embodiment, the first rotary connecting center line  511  is a center line of the first mouth of pipe  51  while the second rotary connecting center line  521  is a center line of the second mouth of pipe  52 . Furthermore, the level-meter  60  is located at a radial slit  512  of the first rotary connecting center line  511  of the pipe joint  50 . 
         [0036]    When the sprinkling head body  10  is mounted, it should be locked to connect along the first rotary connecting center line  511  as shown in  FIG. 4 . Because the level-meter  60  is located at the radial slit  512  of the first rotary connecting center line  511 , for the level-meter  60  the sprinkling head body  10  is rotated to regulate a leveling between the horizon reference surface  61  and the level line of the ground surface. 
         [0037]    Because the first rotary connecting center line  511  can be a radial slit of the second rotary connecting center line  521 , during mounting the sprinkling head body  10  can be locked to connect along the second rotary connecting center line  521  as shown in  FIG. 5  so that the level-meter  60  is slightly rotated and regulated in the radial direction of the second rotary connecting center line  521  for the sprinkling head body  10  to further regulate a leveling between the horizon reference surface  61  and the level line of the ground surface. By using a dual-axis regulating rotation along the first rotary connecting center line  511  and the second rotary connecting center line  521  of the sprinkling head body  10 , the real leveling between the horizon reference surface  61  of level-meter  60  and the level line of the ground surface is accomplished so as to accurately and conveniently regulate effects of spraying direction and spraying range of the outlets on the sprinkling head body  10 . 
         [0038]    Please refer to  FIG. 3  demonstrating a water elevation θ 1  (25 degrees) is formed between the long range sprinkling direction  211  and the horizon reference surface  61 , a water elevation θ 2  (35 degrees) is formed between the short range sprinkling direction  311  and the horizon reference surface  61  and a water elevation θ 3  (zero degree) is formed between the middle range sprinkling direction  411  and the horizon reference surface  61 . Alternatively, when the horizon reference surface  61  is parallel to the level line of the ground surface, the water in the passage  11  moves through the long range outlet  21  and is sprayed out to a front end in an upward inclined manner in the long range sprinkling direction  211 . The water in the passage  11  moves through the short range outlet  31  and is sprayed out to a front end in a downward inclined manner. The water in the passage  11  moves through the middle range outlet  41  and is sprayed out to a front end in a horizontal direction which is parallel to the level line of the ground surface. 
         [0039]    Please refer to  FIG. 6  demonstrating in one embodiment the sprinkling head body  10  can be disposed on a side wall  81  in a tunnel  80 . When a fire occurs in the tunnel  80 , the water sprayed out from the long range outlet  21  can be sprayed on a corresponding lateral wall  82 . The water sprayed out from the short range outlet  31  can be sprayed on a rear side wall  81 . The water sprayed out from the middle range outlet  41  is forming a middle range sprinkling area  42  the size of which is between the long range sprinkling area  22  of the long range outlet  21  and the short range sprinkling area  32  of the short range outlet  31 . By using the water sprayed out from the long range outlet  21 , the short range outlet  31  and the middle range outlet  41 , the whole space in the tunnel  80  can be effectively covered so as to obtain effects of swift heat absorbance and fire coverage. 
         [0040]    Please refer to  FIG. 7  demonstrating a second embodiment of the fire fighting sprinkler device of the present invention which is different from the first embodiment in that no long range sprinkler head  20  is mounted on the sprinkling head body  10 . The sprinkling area of sprayed water in this embodiment is constructed by the middle range sprinkling area  42  of the middle range sprinkler head  40  and by the short range sprinkling area  32  of the short range sprinkler head  30  so that the whole space in the tunnel  80  can be effectively covered by the sprayed water. 
         [0041]    Although the present invention has been explained in relation to its preferred embodiment, it is to be understood that any other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed.
