In addition, as shown in FIG. 8, the coupling surface 201 of the auxiliary deflector 200 has a curved structure on one side thereof so as not to interfere when the ball balancer 144 is separated.

In addition, the installation position of the auxiliary deflector 200 has a close relationship with the deflector 160 which moves inside the body 120 and is exposed to the outside when opened.

Specifically, as described above, as shown in FIG. 5A, the deflector 160 is provided with a sprinkling plate 161 having the sprinkling pieces 161a and 161b divided in half and having different structures. 5D, the spraying piece 161b having an inclined structure is installed so as to be disposed in a direction opposite to the auxiliary deflector 200.

According to an embodiment of the present invention, when a fire occurs, when the heat sensing plate 145c of the heat sensing member 145 constituting the sidewall type sprinkler head 100 is heated by the heat of the flame, the heat of the heat sensing plate 145c is heated. Is transferred to the fuse 147, whereby the fuse 147 is melted to form a gap at the position where the fuse 147 is disposed.

As the gap is formed, the cylinder portion 145a, the heat sensing plate 145c and the heat plate 145d of the thermal member 145 are pushed outward along the fuse piston 146 to the outside of the body portion 120. At the same time, the insulator 148 and the ball balancer 144 also move.

More specifically, when the fuse 147 starts to be molten, as shown in FIG. 8A, the head portion 140 starts to be pushed as much as the melted, elastic member provided in the elastic member guide 132. 133 is extended as the fuse 147 is melted to push the head portion 140, the plurality of balls 143 pushed by the support plate 142 is completely at the locking jaw 122 of the body portion 120 It does not escape and maintains a slightly jammed state. At the same time, the drain hole 111 of the connector 110 continues to be sealed by pushing the valve body 131 in a direction opposite to the direction of pushing the head 140. .

When the fuse 147 is completely melted, the head part 140 is completely detached by the repulsive force of the elastic member 133 which extends, and accordingly, the valve body 131 which is blocking the drain hole 111 of the connector 110 and As the gasket 135 and the pocket ring 136 are moved, the drain hole 111 is opened and the extinguishing water flows into the body 120 to be quickly discharged to the outside, thereby extinguishing.

Here, according to an embodiment of the present invention, in the process of the head 140 is separated from the inside of the body portion 120 to the outside, the compressed elastic member 190 is extended while the second of the deflector assembly 150 The support ring 180 is pushed, and the deflector 160 moves quickly in the longitudinal direction of the body portion 120, so that the head portion 140 detaches more quickly, and at the same time, the valve assembly 130 also quickly. It is exposed from the inside of the body portion 120 to the outside.

In other words, as shown in FIG. 1, basically, the digestive water is filled in the pipe 20 with a predetermined hydraulic pressure, and a force pushing the outer portion of the body 120 to a predetermined pressure acts. The cone-shaped elastic member 190 acts to push the second support ring 180 constituting the deflector assembly 150 and at the same time, the elastic member held in the receiving groove 132b of the elastic member guide 132. Since 133 pushes the piston pin 141, the opening operation can be performed smoothly even if it is installed on the side wall 10 as shown in Fig. 9A.

Therefore, as shown in FIG. 9B, even when the sidewall sprinkler head 100 is installed on the sidewall 10 and positioned in a horizontal state, the above-described hydraulic pressure and the repulsive force of the elastic member to release the head portion 140 are caused. The detachment operation is performed smoothly.

When the separation process of the head portion 140 will be described in more detail, first, as the ball balancer 144 moves, a plurality of balls are provided on one side of the support plate 142 in the circumferential direction due to the support plate 142 being pressed. The force that the 143 is moved in the center direction acts, and thus the ball 143 is moved outward from the inside of the body portion 120.

As the plurality of balls 143 are moved, an end portion of the piston pin 141 inserted through the support plate 142 is separated from the central portion 132a of the elastic member guide 132 and is completely removed from the body portion 120. Are separated.

When the head 140 is completely separated in the body 120, the elastic member 133 held in the receiving groove 132b of the elastic member guide 132 is also elastic member guide 132 by the repulsive force. It is separated from the receiving groove 132b.

At this time, the second support ring 180 is slidably moved outward from the inside of the body 120 by the repulsive force of the elastic member 190 in a compressed state, and at the same time the valve assembly 130 is It moves and is exposed from the inside of the body 120 to the outside.

More specifically, when the second support ring 180 is moved by the repulsive force of the elastic member 190, the deflector 160 coupled through the second support ring 180 and the support member 162 together. When the deflector 160 is moved, the slide is moved through the through hole 173 of the first support ring 170.

In this way, when the second support ring 180 coupled with the support member 162 of the deflector 160 reaches the support plate 171 of the first support ring 170, and then the pushing force continues to act, The first support ring 170 is also moved at the same time.

At this time, the second support ring 180 is moved while being guided along the connecting piece 175 protruding and formed on both sides of the support plate 171 of the first support ring 170.

The first support ring 170 has guide pieces 172 protruding from and formed on both sides of the support plate 171, and the guide pieces 172 are formed in the guide groove 121 formed inside the body part 120. It is inserted so that it can move stably while being guided.

When the first support ring 170 reaches the latching jaw 122 of the body part 120, the movement stops, and as shown in FIG. 9B, the valve assembly 130 is the body part ( 120 is exposed to the outside of the extinguishing water is discharged to the outside is the spraying operation is made as the fire is made.

During the spraying operation, the spraying operation is performed by the spraying plate 161 of the deflector 160 and the spraying operation by the auxiliary deflector 200, so that the spraying operation can be performed near and far, so that the digestion can be performed more efficiently. Can be.

On the other hand, when the first support ring 170 is moved inside the body portion 120, when rotated at a predetermined angle, the inclined sprinkling piece 161b of the sprinkling plate 161 constituting the deflector 160 is It may be located toward the auxiliary deflector 200, in which case, when the extinguishing water sprayed according to the opening is ejected to the outside through the body portion 120, it may not be diffused and deflected may not effectively suppress the fire.

Therefore, when the valve assembly 130 is disengaged, the watering plate 161 of the deflector 160 is moved as it is, so that the diffusion operation is surely performed during the watering operation of the digestive water together with the auxiliary deflector 200. will be.

Moreover, when the extinguishing water having a predetermined hydraulic pressure is discharged to the outside through the body portion 120 through the pipe 20 through the drain hole 111 of the connector 110, the inside of the stretched elastic member 190 Passing through the through hole 184 of the second support ring 180 and the through hole 176 of the first support ring 170 through the through, at the same time the centrally located valve body 131 and the opening around it Erupted through wealth.

Accordingly, as shown in FIG. 9B, the digestion water collides on the outer surface of the valve body 131 having the inclined surface 131b and the straight surface 131c or the valve body 131 having the semicircular curved surface 131d formed thereon. While spreading in the circumferential direction, while continuing to collide with the sprinkling plate 161 of the deflector 160 to spread in the lower direction.

In addition, the valve body 131 having the semicircular curved surface 131d has a slower spray angle of the digestive water than the valve body 131 having the inclined surface 131b and the straight surface 131c, and thus the auxiliary deflector 200. The spraying angle is changed and sprayed downward by colliding toward the distal end side of the deflector plate 202 (the left side of the auxiliary deflector 200 in FIG. 9B), so that the spraying range of the digestive water is further enlarged.

On the other hand, although the spray pattern of the digestive water is not shown in detail in Figure 9b, the horizontal spraying piece 161a formed on the spray plate 161 of the deflector 160 is formed to protrude slightly more than the valve guide 134 As the digestion water passes between the sprinkling pieces 161a and collides with the deflector plate 202 of the auxiliary deflector 200, the angle is changed downward and sprayed.

As described above, a part of the extinguishing water spreading through the sprinkling piece 161a of the valve body 131 and the sprinkling plate 161 collides with the deflector plate 202 of the auxiliary deflector 200 and then changes in a downward direction. Spread out

In other words, the extinguishing water colliding with the auxiliary deflector 200 is sprinkled from a sprinkler head 100 while being sprinkled in a sprinkling direction, and the inclined sprinkling piece 161b formed on the sprinkling plate 161 of the deflector 160. Digestive water that collides with is scattered near and shows a pattern of watering.

Therefore, as the extinguishing water is sprinkled at near and far distances, the extinguishing action is more reliably sprayed than in the prior art, so that the initial suppression of the fire can be made more easily.

While the invention has been described for the embodiments of the invention based on the accompanying drawings for convenience, various modifications and variations are possible within the scope of the technical idea of the present invention, such variations and modifications are claims of the present invention Inclusion within is self-evident.
