BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic fire extinguishing device for an electric switchboard and a panel, and in particular, an actuator body is formed on one side of an injection head in which a packing blocking an outlet of a fire extinguishing liquid is supported by a glass tube, and the motor is driven inside the actuator body. A bolt is formed forward and backward and integrally forms a blow pin that strikes and breaks the glass tube when the bolt is advanced, so that the fire tube is rapidly broken by the operation of the driving motor when a fire detection signal is generated so that the extinguishing fluid is injected rapidly. In addition, by providing an actuator with a simple structure that breaks the glass tube by driving the drive motor to further improve the reliability of the performance of the product as well as to simplify the structure of the product electrical switchboard and to expect the effect of productivity improvement It relates to an automatic fire extinguishing device for a panel.

In general, a fire extinguishing system is not directly installed in power distribution panels, electrical panels of various equipment, etc. in power plants, substations, and electrical rooms in factories and buildings. Halon Fire Extinguishing Facility or Clean Extinguishing Facility, which is operated at the time of occurrence, is installed to be extinguished.

In addition, even in the operation of the Halon fire extinguishing system, CO2 fire extinguishing system, or clean fire extinguishing system installed on the ceiling of the building itself, the switchboard is operated only when it is burned out and the fire spreads into the building. The damage is growing, such as having to reinstall.

Proposed to solve this problem is an automatic fire extinguishing device for switchboard.

A conventional automatic fire extinguishing device for a switchboard is installed in a Halon spray head by heating a heater installed in the Halon spray head by installing a heat and smoke sensitive device inside the switchboard and a panel to electrically convert the detected signal from the control box. The ethanol-embedded glass tube was ruptured by thermal expansion to open the fire extinguisher so that early evolution was achieved.

However, the conventional automatic fire extinguishing device heats the heater by electric signal and detects the fire by rupturing the glass tube containing ethanol by thermal expansion. This is because the glass tube does not burst quickly due to the time difference of heating the heater. Not only was it delayed, but there was also a problem that the rupture was not made correctly.

Therefore, the present invention for solving the above problems forms an actuator body on one side of the injection head, the packing blocking the outlet of the extinguishing fluid is supported by a glass tube, and the bolts forward and backward by the motor drive inside the actuator body Forming but integrally forming a blow pin to the bolt to blow and break the glass tube when the bolt is advanced, so that when the fire detection signal occurs by breaking the glass tube quickly by the operation of the drive motor, the extinguishing fluid is injected quickly, the drive motor drive By providing an actuator with a simple structure that breaks the glass tube, the reliability of the product is further improved, and the structure of the product can be simplified to expect the effect of productivity improvement.

Hereinafter, preferred embodiments for achieving the above object of the present invention will be described with reference to the accompanying drawings, FIGS. 1 and 2.

According to the figure, the present invention is roughly composed of the injection head 10, the actuator 20.

The injection head 10 is rotatably coupled to the pipe end of the automatic fire extinguishing device to inject the extinguishing liquid or extinguishing powder toward the flame in case of fire,

A connecting pipe 11 for connecting to a pipe is formed at the top, and a conduit 11a is formed at the center of the connecting pipe 11, and the conduit 11a is blocked by the packing 12.

Cap 14 is formed below the connecting pipe 11, a plurality of through-holes 15 are formed on the outer peripheral surface of the middle portion of the cap 14, a plurality of discharge holes inclined downward at a predetermined angle ( 16 is formed through.

In addition, a glass tube G is vertically installed inside the cap 14 to support the upper packing 12.

That is, as the glass tube G is broken, the packing 12 is released by the extinguishing liquid pressure in the conduit 11a, and the extinguishing liquid is injected to the outside through the discharge hole 16.

The actuator 20 is driven by the rotational power of the driving motor 30 to damage and damage the glass tube G. The actuator 20 has a predetermined length at the upper end of the injection head 10, that is, the upper portion of the cap 14. Of the bracket 21 and the actuator body 22 to one end of the bracket 21 as a bolt.

A bolt hole 23 is horizontally formed in the middle portion of the actuator body 22, and a female screw portion 24 is formed at one inner circumferential surface of the bolt hole 23.

The bolt hole 23 is fastened in a state in which the bolt 25 is coupled, and one end of the bolt 25 is integrally formed with a blow pin 26 for advancing and hitting the glass tube G. The blow pin 26 enters the cap 14 through the through hole 15 of the injection head 10.

Although not shown in detail on the outer circumferential surface of the bolt 25, a male screw portion 25a corresponding to the female screw portion 24 of the bolt hole 23 is formed.

On the other hand, the drive motor 30 is coupled to one side of the actuator body 22, the spindle 31 of the drive motor 30 is coupled in a state inserted into the center of the bolt 25, the When the spindle 31 rotates, the rotational force is transmitted to the bolt 25 as it is.

Referring to the operation and effects of the present invention configured as described above are as follows.

When the drive motor 30 is driven by the fire detection to rotate the spindle 31 in one direction, the rotational force of the spindle 31 is transmitted to the bolt 25 to rotate the bolt 25, the bolt ( As the 25 rotates, the male thread portion 25a formed on the outer circumferential surface of the bolt 25 is rotated while being inserted into the female thread portion 24, so that the bolt 25 is fast at a predetermined distance within the bolt hole 23. To move forward.

The blow pin 26 formed integrally with the bolt 25 by advancing the bolt 25 enters the cap 14 through the through hole 15 and strikes the glass tube G, thereby preventing the glass tube ( G) is broken so that the packing 12 is separated from the conduit (11a) and the extinguishing liquid is injected to the outside through the discharge hole (16).

The automatic fire extinguishing device of the present invention operating as described above uses the rotational power of the driving motor 30 when fire is detected to rapidly advance the blow pin 26 of the actuator 20 to break the glass tube G to extinguish the liquid. As it is injected, it is possible to extinguish the fire quickly at the beginning of the fire.

As described above, the present invention forms an actuator body on one side of an injection head in which a packing blocking an outlet of the extinguishing fluid is supported by a glass tube, and forms a bolt that moves forward and backward by driving a motor inside the actuator body. By forming the blow pin integrally with the bolt to strike and break the glass tube when the bolt advances, by the operation of the drive motor when the fire detection signal is generated to quickly break the glass tube by spraying the fire extinguishing liquid, by the drive of the drive motor By providing an actuator with a simple structure that breaks the glass tube, the reliability of the product is further improved, and the structure of the product is provided with an automatic fire extinguishing device for electric switchboards and panels that can simplify the structure of the product and improve productivity. You can expect the effect.
