FIG. 4 is an exploded view of a fire extinguisher of an outlet having an extinguishing device according to an embodiment of the present invention, and FIG. 5 is an exploded perspective view of the present invention FIG. 2 is a view showing an operation of an outlet provided with an extinguishing device according to an embodiment of the present invention.

1 to 4, a receptacle 10 according to an embodiment of the present invention includes a main body 11, a cover 12, a sensor portion 13, an insertion protrusion 14, and a fire extinguishing device 100, . ≪ / RTI >

The main body 11 provides a passage through which a plug terminal can be received and electrically connected, and the cover 12 is coupled to the front surface of the main body 11. The sensor unit 13 can sense a fire generated from the rear surface of the receptacle 10.

The sensor unit 13 may include various kinds of sensors, for example, a light receiving sensor. The light receiving sensor can sense the illuminance of the fire according to the fire in the closed space on the rear side of the receptacle 10, and transmits a signal to the fire extinguishing apparatus 100 that a fire has occurred when light above the reference value is detected.

2, the sensor unit 13 may be coupled to the rear surface of the main body 11 of the receptacle 10. The sensor unit 13 may be installed on the left and right sides to minimize the dead zones that the sensor unit 13 can not detect. In this case, a plate having an insertion hole is coupled to the rear surface of the main body 11 of the receptacle 10, and the sensor portion 13 can be coupled to the insertion hole by bolts.

The insertion protrusion 14 is a portion to be fitted to the extinguishing unit 100 and can be inserted into the insertion groove 171 of the extinguishing unit 100.

The fire extinguishing apparatus 100 includes a storage unit 110, a spray nozzle 120, a spray shield 130, and a spraying derivative 140. The fire extinguisher 100 includes a locking unit 150, a locking controller 160, As shown in FIG.

The storage unit 110 is a cartridge for storing the extinguishing agent therein, and can be coupled to the rear surface of the main body 11 of the receptacle 10. Here, the fire extinguishing agent is a fire-extinguishing substance, and may include carbon dioxide (CO ₂ ), water, and the like. The storage unit 110 may include a plurality of storage units.

The injection nozzle 120 is a nozzle connected to the storage part 110 to enable the injection of the extinguishing agent. The injection nozzle 120 is provided with an injection port 121 so that the extinguishing agent can be injected through the injection port 121.

As shown in FIG. 1, the injection nozzle 120 may extend in the longitudinal direction of the socket 10, and the injection orifices 121 may be formed in the injection nozzle 120 in plurality. The injection port 121 can be formed on both sides of the injection nozzle 120 so that the extinguishing agent can be injected to both sides from the injection nozzle 120 for efficient fire suppression. Further, the injection port 121 may be positioned so as to inject the extinguishing agent toward a portion vulnerable to fire.

The spray shield 130 is formed at the end of the spray nozzle 120 to block spraying of the extinguishing agent. The extinguishing agent can not move from the storage part 110 to the injection nozzle 120 side due to the injection blocking film 130. The injection blocking layer 130 may be formed of a polyacetal (POM) resin so as to be removed by the injection derivative 140.

Meanwhile, a moving pipe 131 may be interposed between the storage unit 110 and the injection nozzle 120. The moving pipe 131 provides a passage through which the extinguishing agent can move from the storage unit 110 to the injection nozzle 120. The moving pipe 131 can be bent as needed, but in moving the extinguishing agent, the extinguishing agent can be bent into a curved line to minimize resistance.

As shown in FIG. 1, the storage unit 110 is installed on both sides of the injection nozzle 120, and the moving pipe 131 may also be composed of two. In this case, the jetting shielding film 130 is positioned between the jetting nozzle 120 and the moving tube 131, and the jetting agent 130 in the storage unit 110 flows into the moving tube 131 until the jetting shielding film 130 is removed. You can stay and move.

The jetting derivative 140 is a part for removing the jetting shielding film 130 when there is a fire in the rear surface of the outlet 10. The jetting derivative 140 moves toward the jetting blocking layer 130 at a high speed and can penetrate the jetting blocking layer 130 and break it. Accordingly, when the jetting shielding film 130 is removed, the extinguishing agent can be moved to the jetting nozzle 120 at a high speed by the pressure difference and jetted through the jetting port 121.

The locking part 150 restricts the injection derivative 140 when there is no fire and restrains the incandescent injection 140 having the fire to move the injection derivative 140 toward the injection blocking layer 130 .

The injector 140 may be located inside the injector nozzle 120. In this case, the injector nozzle 120 may be provided with a receptacle 122 for receiving the injector 140. If the spraying derivative 140 is located inside the spraying nozzle 120, even if the spraying derivative 140 destroys the spraying blocking film 130 in the event of a fire, the spraying nozzle 120 itself is not damaged, .

One end of the locking part 150 may pass through the injection nozzle 120 to support the injection valve 140 to restrict the injection valve 140. Even if one end of the locking part 150 passes through the injection nozzle 120, a gap is not formed between one end of the locking part 150 and the injection nozzle 120, so that the extinguishing agent does not flow out.

The jetting derivative 140 may include a body 141, a head 142, a support 143, and an elastic member 144.

The body 141 extends in the longitudinal direction of the injection nozzle 120. The head 142 is formed so as to face the end portion of the body 141 with the spray-blocking film 130 therebetween. The head 142 actually serves to break the jetting blocking layer 130 and may be formed of a material having high durability. The size of the head 142 should be larger than the width of the body 141 so that the jetting guide 140 moves through the hole formed in the jetting shielding film 130 by the head 142.

4, the cross-sectional area of the end portion of the head 142 may become smaller toward the spray-blocking layer 130 side. For example, the end of the head 142 may be pointed or the head 142 may have a rhombic shape. Accordingly, when the fire occurs, the force exerted by the jetting guide 140 on a specific point of the jetting shielding film 130 (for example, the center of the jetting shielding film 130) can be strengthened.

The support portion 143 may be formed on the body 141 as a portion supported by the locking portion 150. The support portion 143 may be formed around the outer circumference of the body 141 and the locking portion 150 may be positioned between the head 142 and the support portion 143 to support the support portion 143. The entire width of the support portion 143 is formed to be smaller than the width of the head 142 so that the head 142 can pass through the hole formed in the jetting shielding film 130.

The elastic member 144 is disposed inside the injection nozzle 120 and presses the support portion 143 toward the spray blocking layer 130, and may include a spring. The elastic member 144 may be located in the receiving portion 122 of the injection nozzle 120 in a compressed state to press the supporting portion 143. [

In this case, the elastic member 144 of the spring can cover the body 141. The elastic member 144 presses one surface of the support portion 143 and the locking portion 150 supports the other surface of the support portion 143 have. Thereby, the jetting derivative 140 can be stably restrained.

Since the elastic member 144 adds a force to move toward the injection blocking film 130 when the injection derivative 140 is released from the constraint, the injection derivative 140 can remove (destroy) the injection blocking film 130 at a high speed ). This improves the accuracy of the breakage of the injection blocking film 130, and the fire suppression can be rapidly performed.

As shown in FIG. 4, the locking part 150 may be formed in an 'H' shape in which two bars are connected to each other. One end of the two bars may pass through the interior of the injection nozzle 120 and be positioned between the head 142 and the support 143.

The locking regulator 160 may move the locking part 150 in a direction away from the injection nozzle 120 to release the constraint of the injection derivative 140. [ The locking control unit 160 may include a wire 161, a rotating body 162, a driving unit 163, and a control unit.

The wire 161 is coupled to the other end of the locking part 150 and may be formed of stainless steel so as not to be unnecessarily broken. Referring to FIG. 3, the direction of movement of the wire 161 may be changed by the pulley 164. By using the pulley 164, space for movement of the wire 161 can be saved.

  The rotating body 162 is a portion to which the wire 161 is coupled. When the rotating body 162 rotates, the wire 161 can be wound. A hole 162a is formed in the rotating body 162 so that the wire 161 can be inserted. The wire 161 can be fitted into the hole 162a.

The driving unit 163 provides power for rotating the rotating body 162, and may include a motor. The rotating body 162 and the motor are fitted to each other without any special parts, and the rotating body 162 can rotate according to the rotation of the motor.

The control unit controls the driving unit 163 according to the occurrence of a fire. The control unit receives a signal from the sensor unit 13 and drives the driving unit 163 when a fire is detected by the sensor unit 13 provided on the rear surface of the socket main body 11. [

If the signal line connected to the sensor unit 13 is disconnected by itself, the MCU loses the pull-down resistance, recognizes that the line is short-circuited, and drives the driving unit 163 . The control unit is equipped with a battery and can be operated by itself, and the battery provides electric power for driving the batch.

When the control unit receives the signal from the sensor unit 13 and drives the driving unit 163, the rotating body 162 pulls the wire 161, and the wire 161 pulls the locking unit 150. The injector 140 is constrained to be released while the locking part 150 moves away from the injection nozzle 120 and the injector 140 moves toward the injection shield 130 and penetrates the injection shield 130 Destroyed. At this time, the locking part 150 is not completely released from the injection nozzle 120 to prevent unnecessary leakage of the extinguishing agent.

Referring to FIG. 5, it can be seen that the spraying derivative 140 removes the spray-blocking layer 130. The supporting part 143 is supported by the locking part 150 supporting the supporting part 143 of the injecting derivative 140 and the compressed elastic part 144 is pressed against the supporting part 143 130 so that the spraying derivative 140 can break the spray-blocking layer 130.

As described above, when the jetting derivative 140 removes the jetting blocking layer 130, the extinguishing agent contained in the storage unit 110 and the moving pipe 131 moves to the jetting nozzle 120 and flows through the jetting port 121 Can be sprayed. As a result, the fire generated at the rear surface of the receptacle 10 can be suppressed.

2 to 4, the outlet fire extinguishing system 100 may further include a frame 170. [0031] Referring to FIGS. The frame 170 may be coupled to the rear surface of the main body 11 of the receptacle 10 so as to fix the injection nozzle 120. [

4, the frame 170 is provided with an insertion groove 171 into which the insertion protrusion 14 of the receptacle body 11 can be inserted. In addition, an opening 172 for inserting the injection nozzle 120 for fixing the injection nozzle 120 is provided.

The frame 170 is provided with a pulley 164 for changing the moving direction of the wire 161 and a space in which the driving unit 163 is seated to protect the driving unit 163. The frame 170 is provided with a guide for moving horizontally when the locking part 150 moves to the rear side. The guide is provided with two bars of the 'H' shaped locking part 150, And may include through holes through which the other ends thereof can pass.

As described above, according to the socket provided with the fire extinguishing device according to the embodiment of the present invention, it is possible to easily suppress the fire generated at the rear face of the socket, thereby preventing a large fire.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention as set forth in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
