Description

Percussion device of auto fire extinguisher system and chain auto extinguisher containing the same

The present invention relates to a fire extinguisher trigger device, and more specifically, to the fire extinguisher trigger device of an automatic fire extinguishing system configured to open fire extinguishers in series by interlocking with other fire extinguishing device operations by sensing fire heat or the surroundings. And it relates to an automatic fire extinguishing device comprising the same.

In general, it is desirable and required for buildings to have a fire extinguisher or the like in preparation for a fire. However, in the case of a general fire extinguisher, not only the user has to purchase and maintain a fire extinguisher separately, but also a user must operate the fire extinguisher so that the extinguishing agent is sprayed. There is a disadvantage.

On the other hand, the objects to be extinguished recently are not limited to simple buildings or devices and records therein, but are increasingly diversified. This is due to the diversification, integration, etc. of the accessory facilities due to the large-scale building, high-rise building, etc. In the trend of diversification and integration of the accessory facilities, it is difficult to quickly suppress fires intensively generated in a specific area by the conventional fire extinguishing facility alone.

Accordingly, in the event of a fire in a specific area, an automatic diffusion fire extinguisher has been proposed to enable rapid initial suppression by spraying a fire extinguishing agent locally. Automatic diffusion extinguisher is a technology that triggers the fire extinguishing agent automatically when the flame or heat is detected when a fire occurs, and is very effective in extinguishing the initial fire.

The auto-diffusion extinguisher is generally composed of a mechanical detection unit for detecting heat or flame, and a trigger for triggering when the detection unit detects heat or flame to open the extinguishing agent storage container. In other words, when the sensing part that has constrained the trigger part to the trigger standby position is broken by flame or heat above a certain temperature, the trigger device is configured to release the extinguishing agent.

However, since most auto-diffusion fire extinguishers have no structure for chain operation, only one point is installed at the highest risk of fire occurrence within a certain fire protection area or several fire risk points are set. Large fire extinguishers were installed at each location to prepare for local fire hazards.

As a result, there is a problem that the fire detection area is limited because the fire detection point is limited to a specific location, and there is a lack of a technology that can operate a series of fire extinguishers in each point after specifying a plurality of fire occurrence points. Due to this, there is a disadvantage that cannot meet the recent trend of requiring a variety of performance for the auto-diffuser.

Thus, when one fire extinguishing device is operated, the prior art that interlocks with each other so that the other fire extinguishing device can be operated in series has been proposed through Korean Utility Model Registration No. 20-0459279. This is characterized in that the heat-sensitive glass tube constituting the device is ruptured, or the extinguishing agent can be released by operating the striking rod by the extinguishing gas of another extinguishing device that is operated first.

However, in the prior art disclosed in the above prior document, when the heat-sensing glass tube is ruptured or operated in conjunction with the extinguishing gas of the other fire extinguishing device, the nozzle head is opened by one striking rod. The striking rod may fail to open the nozzle head normally, and thus, the reliability of the device is deteriorated.

Korea Utility Model Registration No. 20-0459249 (Registration Date 2012. 03. 07)

The technical problem to be solved by the present invention, the fire extinguisher trigger device of the automatic fire extinguishing system that can implement an interlocking trigger system so that when another fire extinguishing device can be operated in series when one fire extinguishing device is operated, and automatic fire extinguishing including the same It is to provide a device.

Another technical problem to be solved by the present invention is to automatically open a fire extinguisher in the event of a fire due to the secondary blowout of the bulb, even if the fire extinguisher is not properly opened at the first trigger by interlocking with another fire extinguishing device. It is an object of the present invention to provide a fire extinguisher triggering device and an automatic fire extinguishing device including the same.

Here, when the bulb ruptures due to fire heat, the restraint of the actuating rod is released and the actuating rod is advanced by the restoring force of the percussion spring installed in the percussion housing so that the first and second percussion pins simultaneously open the nozzle head. When some of the extinguishing agent ejected from the other extinguishing agent storage container is input to the pressure chamber, the piston unit moves forward by increasing the internal pressure of the pressure chamber to independently open the nozzle head independently of the second trigger pin. Can be triggered.

Here, the percussion spring may be a coil compression spring installed between the actuation rod and the percussion housing so that the actuation rod has an elastic restoring force in a direction in which the inlet of the nozzle head is opened.

In addition, a locking groove may be formed on an outer surface of the head of the operating rod, and a locking ball may be installed to insert a portion of the locking groove into the locking groove between the locking groove and the trigger control opening.

In this case, the locking ball, the triggering control device for supporting the locking ball, the bulb for supporting the triggering control device and the support can be aligned in a straight line along a line crossing at right angles to the centerline of the triggering unit.

In addition, the support is screwed to the inner diameter surface of the lower end of the bulb adapter of the percussion control unit may be configured to be adjustable in height.

The trigger housing is connected to a branch pipe extending from another extinguishing agent storage container and has a pressure supply pipe having a flow channel formed therein, and the flow channel of the pressure supply pipe communicates with the pressure port of the pressure chamber at a non-triggered position. It can be configured to. Accordingly, when the other extinguishing device is operated first, some of the extinguishing agent ejected from the extinguishing agent storage container may be introduced into the pressure chamber through the pressure supply pipe to be used as a working fluid for operating the piston unit.

According to another aspect of the present invention as a means of solving the problem,

Extinguishing agent storage container filled with a extinguishing agent in liquid or powder form;

A nozzle head screw-connected to an upper opening of the extinguishing agent storage container and having a head cap formed with a spray hole at one side thereof and a sealing copper plate sealingly coupled to the other side of the counterpart; And

It is coupled to the nozzle head through the head cap, and triggered by the fire extinguishing agent ejected from the fire heat or other extinguishing agent storage containers to open the nozzle head described above; providing an automatic fire extinguishing device comprising a do.

According to an embodiment of the present invention, when a flame or heat is detected, the bulb bursts to allow individual operation to realize automatic triggering, but the pressure of the extinguishing agent ejected when another extinguisher detects fire heat to eject the extinguishing agent By setting it as the working pressure so that the chain can be triggered, it is possible to quickly suppress the early fire and efficiently cope with the fire.

In addition, even if a fire extinguisher is installed at each point after designating a plurality of fire risk points, it has the effect of expanding the fire protection area through a chain reaction, and it is connected to other fire extinguishing devices so that the fire extinguishing agent is classified by area. You may only fill it as appropriate for extinguishing As a result, excessive consumption of extinguishing agents can be reduced.

In addition, even when the nozzle head is not opened by only one trigger pin (second trigger plate) during interlocking operation, a two-stage trigger structure in which another trigger pin (first trigger pin) is continuously triggered by the burst of the bulb due to fire spreading. As a result, the nozzle head attached to the fire extinguisher may not be properly opened even in a triggering operation, so that the risk factors for the fire extinguisher not working properly may be removed, thereby improving device reliability.

Trigger control unit 14 is included. In addition, the piston unit 12 is triggered irrespective of the trigger of the triggering unit 10 by using some of the extinguishing agent ejected from the other extinguishing agent storage container as the working fluid.

The triggering unit 10 is fastened to the nozzle head 2 (see Fig. 6) of the extinguishing agent storage container 3, and in case of fire, the extinguishing agent is opened by striking and opening a specific part of the nozzle head 2 with a great force. Allow to squirt. To this end, the triggering unit 10 may be a structure in which the first triggering pin 105 having the hollow shaft structure and the operation rod 104 having the pressure chamber 106 are elastically housed in the trigger housing 100.

And a cocking spring 108 is installed between the cocking housing 100. At this time, the trigger spring 108 provides elasticity for pushing the actuating rod 104 in the trigger standby state to the triggered position.

Accordingly, when the restraint of the triggering unit 10 by the triggering control unit 14 is released, the actuation rod 104 moves toward the nozzle head 2 at a high speed by the restoring force provided by the triggering spring 108. It is moved and the injection hole 24 of the nozzle head 2 is opened by hitting a specific position of the nozzle head 2 (the sealing copper plate which will be described later) with a large force, and eventually the high pressure filling the extinguishing agent storage container 3 is completed. Extinguishing agents may be ejected to the outside.

The trigger housing 100 may be connected to a branch pipe extending from another extinguishing agent storage container and may have a pressure supply pipe 101 having a flow channel 102 formed therein, and a flow channel 102 of the pressure supply pipe 101. Is configured to communicate with the pressure port 107 of the pressure chamber 106 in the non-triggered position, so that some of the extinguishing agent ejected from the other extinguishing agent storage container 3 flows into the pressure chamber 106 to provide a piston unit ( It is used as working fluid to operate 12).

The piston unit 12 is housed in the pressure chamber 106 formed at a predetermined volume in the center of the actuating rod 104 so as to retreat, ie, in a linear motion, along the axial direction of the actuating rod 104.

The piston unit 12 is preferably a piston 120 and a linear movement in a state in which the outer surface is in close contact with the surface partitioning the pressure chamber 106, and coupled to the center of the piston 120, the first trigger And a second cocked pin 125 installed to form a concentric arrangement with the pin 105.

The piston unit 12 is normally fixed in contact with the rear step surface 106a among the surfaces defining the pressure chamber 106, as shown in the example of FIG. 1, so that the fire rod 108 is activated by the trigger spring 108 in case of fire. When the triggering operation 104 is moved in the direction of opening the nozzle head 2 with the operating rod 104, or the triggering of the triggering unit 10 by the pressure of the working fluid acting on the pressure chamber 106 and Regardless, it moves to open the nozzle head 2.

The first cock pin 105 and the second cock pin 125 have sharp tips, and the second cock pin 125 is concentric in the first cock pin 105 having a hollow hollow shaft structure. By arranging the arrangement, when the piston unit 12 is independently driven by a working fluid (an extinguishing agent of another extinguishing device) input from the outside, the second trigger pin 125 may be the first trigger pin 105. ) It is able to perform stable linear movement in inscribed state.

The main function of the trigger control unit 14 is to restrain the operating rod 104 to the non-triggered position in the trigger housing 100, and to release the restraint of the operating rod 104 in the event of a fire to trigger the extinguishing agent to eject. To allow. The trigger control unit 14 supports the trigger control opening 142, the bulb 144 below the bulb 144, and the bulb 144 below to restrain the operation rod 104 at a non-triggered position in the trigger housing 100. Support 146.

A locking ball 149 is interposed between the trigger control opening 142 and the operating rod 104 to restrict the operating rod 104 to the non-triggered position. The locking ball 149 is placed at the upper end of the trigger control port 142 so as to be in contact with a lower end thereof, and a semi-spherical locking groove having an opposite upper end part formed at an outer surface of the head part 104a of the operating rod 104 ( 109 may be installed to be inserted.

By such a configuration, when the trigger control port 142 descends due to the rupture of the bulb 144 due to fire heat, the locking ball 149 placed on the trigger control port 142 is also lowered together, and the locking groove The actuation rod 104 is released at the moment when the locking ball 149 is released at 109, and the actuation rod 104 is triggered by the elasticity of the trigger spring 108.

The trigger control port 142 and the locking ball 149 are two components such that a part of the locking ball 149 is placed in contact with the trigger control port 142 as illustrated in FIG. 3 may be an independent type, and as illustrated in FIG. 3B, the locking ball 149 may be of an integral type provided integrally with the upper end of the triggering control 142.

Trigger control unit 142 is installed to be elevated up and down inside the upper end of the bulb adapter 140 of the socket structure, the other side of the trigger control unit 142 around the bulb 144, that is, bulb adapter 140 The support 146 may be screwed to the inner surface of the bottom of the bottom. Accordingly, the pressing force of the bulb 144 disposed between the trigger control opening 142 and the constraint force of the triggering unit 10 through the trigger control opening 142 can be adjusted.

The bulb 144 may be a known configuration having a mechanism in which the inner glass expands and the pressure increases when heat above a certain temperature is applied, causing the outer glass tube 144 to rupture. Therefore, when the bulb 144 is ruptured by the heat of fire, the triggering control unit 142 falls down by moment by its own weight and the restraint of the operation rod 104 is released, thereby triggering the triggering by the restoring force of the triggering spring 108 described above. Can be.

Preferably, the locking ball 149, the triggering control 142 for supporting the locking ball 149, the bulb 144 for supporting the triggering control 142 and the support 146 for supporting the bulb 144. ) Is configured to be aligned in a straight line along a line crossing at right angles to the center line of the triggering unit 10, when the bulb 144 is ruptured by a high temperature heat of fire is triggered quickly due to quick trigger response Can be.

Hereinafter will be described the operation of the fire extinguisher trigger device according to an embodiment of the present invention of the above configuration.

Fire extinguisher triggering device according to an embodiment of the present invention can be implemented in two ways largely. One is a trigger that is caused by the bursting of the bulb due to the high heat of fire during the fire and the release of the operating rod, and the other triggered by the operation of the piston unit by the ejection pressure of the other extinguishing system in the vicinity. to be.

The operation of the situation will be described in more detail with reference to the drawings.

4 is an operational state diagram of the fire extinguisher triggering device according to an embodiment of the present invention at the time of bulb rupture.

Referring to FIG. 4, the bulb 144 has a mechanism in which the inner glass expands and the outer glass tube 144 ruptures when the heat is applied above a predetermined temperature and the pressure increases. Therefore, when the heat due to the fire is directly and indirectly transferred to the bulb 144, the glass tube 144 is ruptured and removed, and the trigger control port 142 falls down instantaneously by its own weight to the operating rod 104. The restraint is released.

Accordingly, the piston unit 12 along with the actuating rod 104 momentarily advances toward the nozzle head 2 (see FIG. 6) with the restoring force of the cocking spring 108, thereby first and second cocking pins 105 and 125. At the same time to hit a certain portion of the nozzle head (2) with a large force at a moment. As a result, the injection port 24 of the nozzle head 2 is opened and the extinguishing agent in a liquid or powder form filled with the extinguishing agent storage container 3 at high pressure is ejected.

5 is a view showing an operating state diagram in a chain operation situation by the ejection pressure of the surrounding other fire extinguishing device.

Referring to FIG. 5, when another extinguishing device is operated by sensing heat first, some of the extinguishing agent ejected from the extinguishing agent storage container 3 of the extinguishing device is branched through a branch pipe (not shown). Is input to the percussion apparatus according to the embodiment of the. Specifically, some of the extinguishing agent of the fire extinguishing device that is operated first is introduced into the pressure chamber 106 inside the operating rod 104 through the branch pipe and the pressure supply pipe 101.

Due to the extinguishing agent filled in the pressure chamber 106, the internal pressure of the pressure chamber 106 rises, and thus the piston unit 12 moves forward toward the nozzle head 2 at a high speed. At this time, the second cock pin 125 hits a specific part of the nozzle head 2 with a large force, and accordingly, the injection hole 24 of the nozzle head 2 is opened and a high pressure is applied to the extinguishing agent storage container 3. Fire extinguishing agents in filled liquid or powder form may be ejected.

That is, in the fire extinguisher triggering device according to an aspect of the present invention, when the bulb 144 is ruptured due to fire heat, two triggering pins 105 and 125 are simultaneously triggered to open the nozzle head 2, and another extinguishment. When the interlocking operation with the device is configured to open the nozzle head 2 with only one triggering pin (second triggering pin), individual operation is possible, but interlocking with other fire extinguishers is possible.

In addition, when the nozzle head 2 is not opened by only one triggering pin (second triggering plate) during interlocking operation, the other triggering pin (first triggering pin 105 is caused by the bursting of the bulb 144 due to fire spreading). The nozzle head 2 can be opened once again by triggering successively)). Accordingly, the nozzle head (2) does not open in case of fire can eliminate the risk factors that the fire extinguisher does not operate normally.

On the other hand, Figure 6 is another preferred embodiment of the fire extinguisher trigger device, if the initial fire occurs when a person directly recognizes the fire occurs by manually triggering the fire extinguisher trigger device according to the present invention to add a manual trigger line so that a rapid fire suppression can be made One embodiment.

6, the fire extinguisher triggering device according to another embodiment of the present invention may further include a manual triggering line 20. The main function of the manual triggering line 20 is to allow the triggering operation by artificially releasing the restraint of the triggering unit 10, and to cause the above-described bulb 144 to rupture with physical force or to be released from a designated position, triggering the triggering. The unit 10 may be configured to release.

Passive triggering line 20 is preferably connected to or connected to the bulb 144, as shown in Figure 7 and the wire cable 22 extending outside the fire extinguisher triggering device according to the present invention, and the wire cable from the outside of the device It may be a configuration including a trigger handle 84 provided to be connected to the distal end of the (22).

The manual triggering line 20 applied to the present embodiment may be usefully used as a means for immediately operating the triggering device according to the present invention prior to the automatic triggering when a fire is not detected early and a person directly recognizes the occurrence of a fire. Can be. That is, by triggering the triggering unit manually before the automatic triggering can be used to extinguish the fire more quickly early by the fire extinguishing agent is injected.

7 is a schematic cross-sectional view of an automatic fire extinguishing device according to another aspect of the present invention.

Referring to FIG. 7, the automatic fire extinguishing device is screw-coupled to an upper opening of the extinguishing agent storage container 3 filled with a high-pressure extinguishing agent in a liquid or powder form and the upper opening of the extinguishing agent storage container 3 with a spray hole on one side thereof. And a nozzle head 2 having a head cap 21 formed thereon and a sealing copper plate 23 sealingly coupled to the other side of the opposing part.

The automatic fire extinguishing device also has the above-mentioned percussion device 1 coupled to the nozzle head 2 via the head cap 21. Since the triggering device 1 is identical to the triggering device described above, duplicate descriptions of the same configuration will be omitted, and only other components will be briefly described.

Extinguishing agent storage container 3 may be installed on the ceiling or wall surface of the installation target. The extinguishing agent storage container 3 is filled with a extinguishing agent in a liquid or powder form at a high pressure. Preferably, it is hermetically stored in a filled state to maintain a pressure of about 10 bar, an opening is formed at an upper end (in some cases, a lower end or side), and the nozzle head 2 for ejecting extinguishing agent is coupled to the opening. do.

The nozzle head 2 includes a head cap 21 in which an injection hole 24 is formed at one side and a sealing copper plate 23 is hermetically coupled to the opposite side. In detail, a flow passage 25 communicating with the opening of the extinguishing agent storage container 3 is formed therein, the head body 20 having the gas accommodation chamber 22 and the injection port 24, and the gas accommodation chamber 22. The valve body 28 is provided with an elastic force in a direction to open the injection hole 24 through the tension spring 26 inside the).

The valve body 28 serves to close the injection port 24 while disconnecting the gas accommodating chamber 22 and the flow path 25 in the middle, and the sealing copper plate (at the inlet side of the gas accommodating chamber 22). The gas receiving chamber 22, which is partitioned between the valve body 28 by sealing 23 through the head cap 21, is kept in a completely closed state. In addition, the pins 105 and 125 of the triggering device 1 are fastened to the head cap 21 in a structure spaced apart from the sealing copper plate 23 at a predetermined interval.

By such a configuration, when the trigger unit 10 is triggered by the rupture of the bulb 144 due to the fire heat, or when the piston unit 12 is triggered in conjunction with the operation of other fire extinguishing devices, the trigger pin 105 or And the sealing copper plate 23 is torn and opened by the triggering action in which the sealing copper plate 23 strikes the sealing copper plate 23 with a large force at a moment, and the gas in the gas receiving chamber 22 is discharged to the outside to open the valve body 28. The pressure that was pushing is removed.

This causes the valve body 28 to retreat in the direction of opening the injection port 24 by the restoring force of the spring 26, and eventually the flow path 25 and the injection port 24 are opened. Accordingly, the extinguishing agent may be ejected through the injection port 24 at the pressure of the extinguishing agent that has been filled with high pressure in the extinguishing agent storage container 3, and may be sprayed with a predetermined pressure and an even distribution toward the extinguishing object.

Reference numeral 29 denotes that some extinguishing agents act on the other extinguishing device when the extinguishing agent filled at high pressure in the extinguishing agent storage container 3 is ejected to the outside through the injection port 24 as the valve body 28 is opened. It refers to a pressure branch that is branched from the head body 20 to be supplied to the fluid and the branch pipe (not shown) is connected.

According to the embodiment of the present invention, when the flame or heat is detected, the bulb is bursting, and the individual operation is possible to implement the automatic trigger, while the other extinguishers around the fire to detect the fire heat to eject the extinguishing agent of the extinguishing agent By configuring the pressure to be the operating pressure to be a series of triggers, it is possible to quickly suppress the early fire and efficiently cope with the fire.

In addition, even if a fire extinguisher is installed at each point after designating a plurality of fire risk points, it is effective to expand the fire protection area through a chain reaction. You may only fill it as appropriate for extinguishing. As a result, excessive consumption of extinguishing agents can be reduced.

In addition, even when the nozzle head is not opened by only one trigger pin (second trigger plate) during interlocking operation, a two-stage trigger structure in which another trigger pin (first trigger pin) is continuously triggered by the burst of the bulb due to fire spreading. As a result, the nozzle head attached to the fire extinguisher may not be properly opened even in a triggering operation, so that the risk factors for the fire extinguisher not working properly may be removed, thereby improving device reliability.
