In general, fire extinguishers are mandatoryly installed in fire-fighting areas such as kitchens of multi-family houses such as apartments and kitchens of general restaurants, so that fires can be quickly suppressed to reduce property and casualties.

Then, a pressurized type for extinguishing liquid is ejected by using the pressure generated by operating the detonation cartridge, and the gas is injected into the container together with the extinguishing liquid to be blocked by the valve and then filled with the valve. Some types of accumulators allow extinguishing fluid to be ejected by gas pressure.

In addition, in general, when a fire occurs, the fire is extinguished quickly by using a fire extinguisher, and when the size of the fire becomes large, it is difficult to extinguish the fire by extinguishers.

Such fire extinguishers are classified into fire extinguishers in which gas is injected, fire extinguishers in which liquid is injected, and fire extinguishers in which powder is injected, depending on the type of extinguishing agent. Fire extinguishers mainly used in homes and offices are powder fire extinguishers in which pink powder is sprayed and accumulators.

Fire extinguishers are also classified according to their use, such as Class A fire extinguishers for ordinary fires such as wood, Class B fire extinguishers for oil fires, Class C fire extinguishers for electric fires, and Class D fire extinguishers suitable for fires caused by metal or metal powder. It is classified as a fire extinguisher.

On the other hand, when the actual fire occurs, there is a first fire suppression that is operated by the heat sensor and a second fire suppression that is suppressed as the temperature continues to rise. There is also a need to be able to produce an automatic fire extinguisher that operates accurately while reducing costs.

Of course, the Republic of Korea Patent No. 10-0716473, "The housing is screwed to the inlet portion of the fire extinguisher with a fire extinguishing liquid and the inside is provided with a packing, ball, ball adjustment shaft, mood bolt and ejection guide pipe, In the automatic fire extinguisher comprising an injection nozzle coupled to the injection horn on the upper portion, and an operation device attached to the ball adjusting shaft of the housing to control the extinguishing liquid injected through the injection nozzle, the operating device generates a driving force A motor, a plurality of gears coupled to the shaft of the motor and for transmitting to the ball adjusting shaft in a state in which the driving force of the motor is decelerated, and a spring provided in one of the gears to rotate the ball adjusting shaft with elastic force.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The construction of the present invention and the effects thereof will be clearly understood through the following detailed description.

In addition, detailed description may be abbreviate | omitted about a well-known technical structure.

On the other hand, the process of installing the fire extinguisher of the present invention may follow a general method, that is, the fire extinguisher of the present invention is installed in a suitable place by tightening screws or other fixing means, and also install the sensor to install the sensor Ensure that the output is connected to the fire extinguisher. Then, the fire extinguisher is connected to the tube for connecting the compressed air, and then let the air enter.

1 is a view showing a control unit connected to a fire extinguisher in a switchboard.

In general, the first initial suppression proceeds by opening (compressed) the compressed air input valve using an external electric signal to introduce external compressed air into the fire extinguisher. At the same time as the compressed air is introduced, the valve of the discharge port is opened, and the extinguishing agent is discharged to the discharge port to extinguish the fire. And the solenoid valve serves to open the compressed air and discharge the extinguishing agent. Of course, in addition to the method of allowing the compressed air to be discharged to discharge the extinguishing agent from the outside, the extinguishing agent is provided in the extinguisher sealed with the compressed air, the extinguishing agent may be discharged by the force of the compressed air inside the extinguisher, and the present invention Both of the above methods are applied.

1 is a view showing the configuration of the control unit, in the present invention, the components configured in the block diagram of FIG. That is, the control unit 125 for controlling the overall signal and the operation of the fire extinguisher valve, the smoke detection sensor 130 for detecting the smoke, the temperature sensor 140 for detecting the temperature and the flame detection sensor 135 for detecting the flame Is provided to act as a primary fire suppression.

Meanwhile, a display 127 on which related information and data are displayed and an input unit 126 for inputting related information and data are further provided, and a communication unit 128 for communicating information through a central center and a wired or wireless network is also provided. Also, the alarm unit 129 for informing the emergency situation by sound or light is further provided.

In addition, by detecting the sensor provided in combination to reduce the additional malfunction as possible. That is to combine the data of the sensor provided to produce a sensing output to operate the fire extinguisher. And, the method of outputting the sensing to operate the fire extinguisher by combining the data of the sensor is as follows.

(1) The control unit 125 of the present invention emits only the output for early checking, unless the smoke enters the reference temperature even though the smoke detection sensor 130 detects the smoke due to the inflow of other places. In this case, the controller 125 may operate the alarm unit 129.

(2) When the supply of external compressed air and N2 gas is not smooth, a pressure sensor that can raise an alarm for system inspection may be further provided. (It is omitted in Figure 1 of the present invention, but the configuration of Figure 1 In other words, if the pressure value sensed by the pressure sensor does not reach the reference value, the control unit 125 of the invention may output the alarm signal by operating the alarm unit 129. There is a number.

On the other hand, fires in switchboards can be caused by electric fires. That is, sparks are generated due to poor contact, and smoke is generated when heat is generated along with sparks when continuous sparks occur. In this case, three factors of spark (spark), heat, and smoke are generated, and the fastest one among the three factors is a flame, and then smoke is sensed and heat is sensed. In addition, when the sensing by the heat is started, the damage caused by the fire is more concerned than the initial suppression. The sprinkler, which is most used for automatic fire extinguishing due to the thermal structure, cannot be seen as an initial suppression inside the switchboard.

At this time, the present invention is to achieve an initial suppression, for this purpose, to provide a fire extinguisher controlled by an external signal in the state of the initial detection technology based. In addition, in order to not affect the electrical and electronic equipment during the initial suppression, in the present invention, a clean extinguishing agent (Halon, Novec 123, etc.) is used as a fire extinguishing agent.

(3) When smoke and flame are detected after the temperature rises above the standard temperature, extinguishers are operated by using external pressurized compressed air or N2 gas. In the case of a switchboard, the reference temperature is usually 40 degrees Celsius or less. At the 40 ° C reference site, temperatures of 45 ° C and 50 ° C are checked, flames and smoke are detected and real-time monitoring for a fixed period of time.

That is, when the temperature above the reference temperature is sensed by the detection of the sensor 140, smoke and flame are detected by the smoke detection sensor 130 and the flame detection sensor 135, respectively, the control unit 125 of the present invention is a fire extinguisher ( Operate the sole valve 110 of 100 to proceed with the operation of the fire extinguisher. (1st initial suppression)

At this time, the controller 125 may perform time sensing, and thus, when a detection signal generated by the sensor is generated for a predetermined time (for example, 5 seconds or 10 seconds), the first initial suppression is performed.

Of course, when a temperature of 40 degrees or 45 degrees is sensed by the temperature sensor 140, the controller 125 operates the alarm unit 129 (early check) before the initial initial suppression is performed. You can also let this go.

In addition, if the detection of the smoke or flame lasts more than 10 seconds by the flame detection sensor 135 or the smoke detection sensor 130, the control unit 125 operates the alarm unit (early check output).

In addition, although heat is not sensed by the temperature sensor 140, when smoke or flame is detected through the flame detection sensor 135 or the smoke detection sensor 130, the controller 125 operates the alarm unit. (Early check output)

(4) The above-mentioned sensors can be installed in a plurality of places in the distribution panel, and the combined fire extinguisher operation can be performed by combining the data with each other by the above method.

It also includes a main program that can send multiple sensors to a central management system to analyze data and manage the site. That is, through the communication unit 128 of FIG. 1 and through the wired / wireless network, the controller 125 controls the signal information detected by the flame detection sensor 135, the smoke detection sensor 130, or the temperature sensor 140. Data) can be transmitted to the central center 225, and thus, the central center 225 is connected to a plurality of control units 125 of the present invention.

(5) the reference detected by the flame detection sensor 135, the reference detected by the smoke detection sensor 130, the reference detected by the temperature sensor 140 and the time controlled by the controller may be changed by the user. Of course.

That is, a reference detected by the flame detection sensor 135, a reference detected by the smoke detection sensor 130, a reference detected by the temperature sensor 140, and a time controlled by the controller are newly input through the input unit 126. If the information is newly input, the controller stores the newly input information in a memory (although not shown in the embodiment of FIG. 1, the algorithm and data for operating the controller are stored). In addition, the controller 125 operates the alarm unit 129 or the sole valve 110 by the newly input reference when the sensor 130, 135, 140 receives and controls the signal.

(6) The display 127 shows the reference of the sensor and the operating state of the fire extinguisher. That is, the information displayed on the display 127 may be manipulated through the input unit 126 in a conventional manner. Accordingly, the display 127 may detect the reference and smoke detection sensor 130 that are detected by the flame detection sensor 135. The reference detected by), the reference detected by the temperature sensor 140 is displayed. In addition, data of the sensor signals sensed and output by the sensors 130, 135, and 140 are also displayed on the display 127, and a situation when the controller 125 operates the fire extinguisher is also displayed.

2 is a view of an embodiment showing a fire extinguisher of the present invention.

Fire extinguisher of the present invention is composed of a damper 105 for operating the thermal material 160, the case 120 is filled with a fire extinguishing agent, the sole valve 110 and the body (115) for the secondary fire suppression. .

In general, the first initial suppression proceeds by opening (compressed) the compressed air input valve using an external electric signal to introduce external compressed air into the fire extinguisher. At the same time as the compressed air is introduced, the valve of the discharge port is opened, and the extinguishing agent is discharged to the discharge port to extinguish the fire.

In addition, even when the first initial suppression was attempted but the solenoid valve was not opened due to a short circuit of the wire due to the fire, the heat-sensitive body reaction by the temperature outside the fire extinguisher 100 and the damper due to the pressure inside the fire extinguisher 100 105) The inner valve reacts to open the inner cover. And the second fire suppression is performed by the above operation.

General merchandise such as sprinklers may be used as the product of the thermally sensitive member 160 reaction structure. That is, a heat fuse, a fuse bulb, a glass bulb head is used. That is, a heat fuse, a fuse bulb, a glass bulb head is used. Or lead alloys will be used.

On the other hand, in the process of the second fire extinguisher, the thermal element 160 is liquefied and ejected to the outside of the fire extinguisher together with the extinguishing agent, a problem that may be a foreign object in the fire place. However, the thermal element 160 provided in the fire extinguisher 100 of the present invention remains in the fire extinguisher even after the operation of the secondary fire suppression, and has a feature that does not foreign matter at the fire site.

That is, when the thermal body 160 is ejected to the outside of the fire extinguisher 100, the fire extinguisher is installed in the product having an electrical property such as a distribution panel, characterized in that, the environment around the fire extinguisher in which the thermal body 160 is conductive It can act as a foreign material to cause a third fire, the present invention provides a structure to solve this problem.

3 to 5 is a diagram of an embodiment showing a cross-sectional structure of the fire extinguisher of the present invention.

3 is a view of an embodiment showing a fire extinguisher case, the case 120, the extinguishing liquid 145 is filled, the damper 105 is located at one end of the case 120, the other end is finished 150 Will be located.

FIG. 4 is a view illustrating an example of a cross section of a damper. The damper 105 includes a heat sensing body 160, a heat sensing plate 165, a nozzle 155, and a fire extinguishing liquid 145.

5 is a view showing a cross section of the components of the damper. As illustrated in FIG. 5, a heat sensing body 160 is present inside the damper 105, and a heat sensing body plate 165 surrounding the heat sensing body 160 is provided, and the heat sensing body plate 165 has a spring. It is attached, and has a structure in which the nozzle is coupled to the spring.

In the present invention, during the operation of the fire extinguisher by the first initial suppression will be used eco-friendly fire extinguishing agent does not affect the space other than the fire generating unit. Environmentally friendly fire extinguishing agents are electrically insulating and do not affect the electrical appliances around them. In addition, since the extinguishing agent has a liquid phase and a vaporization structure thereafter, no separate cleaning is necessary after spraying the extinguishing agent.

When the control unit 125 outputs the operation of the fire extinguisher by the method of the embodiment of FIG. 1, the control unit 125 sends an electric signal, and the solenoid valve 110 attached to the fire extinguisher 100 is connected to the electric signal. It is opened by the compressed air outside the fire extinguisher is introduced into the fire extinguisher, the extinguishing liquid 145 is injected out of the fire extinguisher (100).

At this time, the extinguishing liquid injection power is used commercial (public) N2 gas, compressed air, etc., which are prepared inside the distribution panel, a separate compressed air reservoir is used, or a pressure mixed fire extinguisher is used. Of course, when there is no commercial pressure outside the fire extinguisher, a filling type fire extinguisher with compressed air is used.

The sole valve 110 is connected to the compressed air input stage and the extinguishing liquid discharge end. When the sole valve 110 is operated by an electric signal of the controller 125, the compressed air input stage and the extinguishing liquid discharge end are operated at the same time.

The injected compressed air becomes a driving force for discharging the extinguishing liquid (digestive chemical) 145 therein and pushes the extinguishing chemical to the discharge nozzle at a pressure. The extinguishing liquid (extinguishing agent) 145 is in a liquid or gaseous state, and when the liquid is forced out, the liquid is particulated and sprayed by the spray nozzle, and the injected extinguishing agent is discharged in the installation direction of the upper, lower, left, and right nozzles, and the extinguishing proceeds.

When a problem occurs in the forced injection method using the sole valve 110, the extinguishing fluid (or extinguishing) using a temperature-sensitive valve (spring cooler, damper, bulb head, etc.), etc., which depends on the extinguisher 100 as an alternative method. Drug) is discharged. The failure may be caused by a problem corresponding to the control controller (control unit 125) in the distribution panel inside the electrical operation, or a failure may occur in the function of sending an electrical signal to the solenoid valve.

In the present invention, the damper 105 is used as a temperature-sensitive valve. That is, when a problem occurs in the initial initial suppression by causing a failure in the forced injection method using the sole valve 110, the thermal element 160 inside the damper 105 reacts for the secondary fire suppression. do.

That is, when the temperature around the fire extinguisher rises by more than a predetermined standard, the temperature of the fire extinguisher 100 also increases, and the temperature of the damper 105 also increases, and as a result, the temperature of the heat sensing body 160 also increases.

As shown in FIGS. 4 and 5 of the present invention, the thermal element 160 is present between the outer side surface 160a of the damper 105 and the thermal element plate 165. When the temperature of the thermal element 160 rises due to the fire around the fire extinguisher 100, the thermal element 160 melts, and when the space occupied by the thermal element 160 decreases, the side of the thermal element plate 165 is provided. Due to the spring action, the thermal element plate 165 is pushed in the direction in which the thermal element 160 is present (in the direction of the arrow in FIG. 4), and in the process, the nozzle 155 is opened to extinguish the liquid (digestive medicine) ( 145 is ejected out of the fire extinguisher 100.

FIG. 6 is a view illustrating a plane and a side surface of a heat sensing body, and a view showing an embodiment in which a space in which a heat sensing body exists is formed.

FIG. 6A is a diagram of an embodiment in which the space 160a (the area of the empty space in which the heat sensitive agent does not exist) exists in the heat sensitive body 160.

When the heat sensitive body 160 of the present invention is melted by heat, the volume occupied by the heat sensitive body 160 is reduced. For this purpose, the heat sensitive body 160 of the present invention has a space 160a (the heat sensitive agent is present in the heat sensitive body). Do not exist). That is, when the thermal member 160 is melted, the thermal member is filled in the space 160a, and as a result, the volume occupied by the thermal member 160 is reduced.

Therefore, even if the heat absorber 160 melts, the heat absorber having the reduced volume occupies the gap between the side of the damper 105 and the heat absorber plate 165 so that the heat absorber is not ejected to the outside of the fire extinguisher. That is, the volume occupied by the heat-sensitive body melted by heat decreases, and thus remains inside the damper 105.

If the thermal element is ejected to the outside of the fire extinguisher may be foreign matter at the fire site, in the present invention, even after the second fire extinguishing, the thermal element 160 remains inside the fire extinguisher, thereby eliminating the cause that the thermal element may act as a foreign substance. do.

That is, in the prior art, the thermal element is configured on the side of the extinguishing passage of the nozzle, but in the present invention, the thermal element is present between the outer case (cover) side 160a of the damper and the thermal element plate 165 so that the thermal element can be sensitive to temperature. Avoid direct contact with extinguishing agents, which do not spill out. In addition, it is a structure that is formed outside the nozzle, not the structure of the nozzle and serves to serve as a thermal element as part of the damper.

FIG. 6B is a view of an embodiment in which the thermal element 160 is partially formed.

As shown in FIG. 6B, the thermal element 160 partially exists between the outer case (cover) side surface 160a of the damper and the thermal element plate 165, and thus, when the thermal element 160 melts, The volume occupied by the thermal element 160 is reduced. This is because when the thermal element melts, it fills even the part where the thermal element does not exist.

FIG. 6C is a diagram of an embodiment in which a space is formed on the outer case (cover) side surface 160a of the thermal element plate 165 or the damper.

Therefore, when the thermal element 160 melts, the thermal element 160 is filled in the space of the outer case (cover) side 160a of the thermal element plate 165 or the damper.

As a result, in the present invention, there is a space in which the thermal element exists between the thermal element plate 165 and the outer case (cover) side surface 160a of the damper. When the thermal element 160 melts, the volume of the space in which the thermal element exists is reduced as in the embodiment of FIGS. 6A, 6B, and 6C. When the volume of the space in which the thermal element is present is reduced, the direction in which the thermal element 160 is present in the thermal element plate 165 is present by the spring action provided on the side of the thermal element plate 165 (FIG. 4). In the direction of the arrow), the nozzle 155 is opened in the process, the extinguishing liquid (digestive medicine) 145 is ejected out of the fire extinguisher (100).

That is, when the space in which the heat-sensitive material exists (the space in which the heat-sensitive material made by the heat-sensitive material plate 165 and the outer case (cover) side 160a of the damper exists) is reduced, the spring provided on the side of the heat-sensitive material plate 165. 4, the valve is opened when the heating plate 165 moves in the direction of the arrow in FIG. 4 (the process of opening the valve can be easily applied in a general general method, so a detailed description thereof is omitted). When the valve is opened, the nozzle 155 is opened so that the extinguishing liquid is ejected.

7 is a diagram illustrating an embodiment of a method in which a control unit and a central center are connected.

In the central center 225, a control unit serving as a central processing unit, a database storing information, a communication unit communicating information to a wired / wireless communication network, a display on which information is displayed, and an input unit for inputting information are present.

As described in the embodiment of FIG. 1, the data collected through the controller 125 is transmitted to the central center 225, which is a higher level device, by using a wired or wireless network. In this case, the control unit 125 also includes a memory unit for storing information. The memory unit also stores an algorithm program for the control unit to perform a function, and also stores information output from a sensor and a sensor detection condition.

Meanwhile, as shown in FIG. 7, a plurality of control units 125-1, 125-2, and 125-n are connected to the central center 225 via a wired or wireless network, respectively. The fire extinguisher 100 is connected to each of the plurality of controllers 125-1, 125-2, and 125-n. Accordingly, the central center may operate one of the fire extinguishers by selecting one of the plurality of control units 125-1, 125-2, and 125-n. The above function is performed by the control unit of the central center through the communication unit.

That is, among the plurality of control units 125-1, 125-2, and 125-n provided in each distribution panel, the data received from a specific control unit 125 is determined based on a reference value (a reference value stored in a database of the central center). When the reference value according to the previous embodiment of the present invention) is exceeded, the central center 225 may transmit a fire extinguisher operation signal to the control unit 125 that transmits data that is out of a predetermined standard. Then, the control unit 125 receives the operation signal of the fire extinguisher 100 from the central center 225 operates the fire extinguisher connected to the control unit 125. (The fire extinguisher is operated according to the foregoing description of the present invention. The above function is performed by the control unit of the central center through the communication unit.

Meanwhile, the controller 125 transmits the data collected through the sensors connected to the controller to the central center 225 through a wired or wireless network, and the central controller manages each controller and the fire extinguisher status based on the received data. .

In addition, through the input unit of the central center 225, one of a plurality of controllers connected to the central center 225 is selected, and the reference, smoke detection sensor 130 is detected by the flame detection sensor 135 in the selected control unit The criteria detected by the reference, the criteria detected by the temperature sensor 140 and the condition of the monitored time may be input again. That is, when the new condition is input through the input unit of the central center 225, the controller of the central center transmits data of the new condition to the selected controller through a wired / wireless network, and the selected controller controls the received information. Save as a new condition in the memory unit connected with.

8 is a view of an embodiment in which the display unit is attached to the fire extinguisher.

Sensors 103 and 104 are provided inside the fire extinguisher, and the sensor detects a state inside the damper 105 and a pressure inside the fire extinguisher. Therefore, the embodiment of FIG. 8 shows an example in which two sensors are provided like the sensor 1 and the sensor 2, but in fact, the sensor may be further provided.

As a sensor for sensing the inside of the damper 105, there may be a sensor for detecting a distance between the thermal element plate 165 and the damper outer side 160a. That is, when a problem occurs in the thermal element 160 and the volume of the space in which the thermal element 160 is present decreases, the distance between the thermal element plate 165 and the damper outer side 160a shown in the embodiment of FIG. 4 is reduced. Will be reduced. Therefore, it is possible to detect the state of the thermal element 160 by the sensor for detecting the distance. When the distance is reduced, a resistance sensor having a reduced resistance value may be used as a sensor for detecting the distance.

In addition, an example of a sensor for detecting a state inside the fire extinguisher may be provided with a pressure sensor. That is, a pressure sensor may be provided inside the pipe connected to the sole valve, and a pressure change may be detected inside the pipe. If the pressure is lowered, a problem occurs in the pressure of the gas connected to the solenoid valve, which may cause a problem in the discharge of the extinguishing liquid. In addition, the sensor to detect the pressure inside the fire extinguisher can determine whether the valve is open.

The information output from the sensors 103 and 104 is input to the central processing unit (CPU) 101, and the central processing unit (CPU) 101 outputs information equal to or less than a reference value. Determine if it is abnormal. In addition, the CPU 101 may display information output from the sensors 103 and 104 through the display unit 102, and may also display the reference value or less.

In this case, the display unit of the present invention may be a conventional display capable of displaying data values, but may be a simple lamp. That is, when the sensor value received by the sensor 103 or 104 is less than or equal to the reference value, the color of the display unit formed by the CPU 101 lamp may be changed. That is, when the sensor value received from the sensors 103 and 104 is equal to or less than or equal to the reference value, the CPU 101 sets the color of the display unit 102 including the lamp to red, and the reference value. If it is within, the color of the display part 102 which consists of lamps can be made green.
