Description

The present invention relates to a wire connection mechanism, a wire connection method, and a fire extinguishing equipment and fire extinguishing method.

BACKGROUND ART Conventionally, gas-based fire extinguishing equipment has been widely used that extinguishes a fire using an inert gas such as nitrogen gas, carbon dioxide, halogen gas, or a mixed gas of nitrogen, carbon dioxide, and halogen gas as a fire extinguishing gas. When extinguishing a fire, the above-mentioned various gases used for extinguishing the fire are released from a storage container into the compartment to be extinguished.

Until now, for example, when supplying extinguishing gas to multiple sections to be extinguished, in order to selectively supply the extinguishing gas to the sections to be extinguished, a container for extinguishing agent corresponding to each section to be extinguished has been used. (Typically, a "fire extinguishing gas cylinder"), a selection valve corresponding to each of the extinguishing agent containers, and a starting gas container corresponding to each of the selection valves are installed in the gas fire extinguishing equipment. (Patent Document 1).

Japanese Patent Application Publication No. 11-347145

Due to the above-mentioned circumstances, multiple problems have arisen, especially in gas-based fire extinguishing equipment that requires multiple starting gas containers. Specifically, an increase in the burden of inspection work or maintenance of the pressure in the startup gas container of the startup gas (e.g., carbon dioxide gas), and an increase in the burden of performance inspection or maintenance of the container valve provided in the startup gas container. Multiple problems have arisen, such as an increase in the number of starting gas containers, an increase in the burden of maintaining piping between each starting gas container and the selection valve, etc., and an increase in equipment costs due to an increase in the number of starting gas containers. There is.

In addition, in gas-based fire extinguishing equipment that uses a starting gas container, electrical signals from sensors etc. may be erroneously sent to valves such as solenoid valves or electric valves as well as the container valve of the starting gas container. Occasionally, a malfunction problem may arise in which unnecessary extinguishing gas is released into the area to be extinguished.

Therefore, there is a strong desire to realize a fire extinguishing system that can reduce the number of starting gas containers and can highly accurately discharge extinguishing gas only to the area to be extinguished.

The present invention can greatly contribute to the realization of fire extinguishing equipment in which a single starting gas container is responsible for opening a plurality of selection valves and can discharge extinguishing gas only to the area to be extinguished with high accuracy.

In order to selectively supply extinguishing gas to a necessary section among a plurality of sections to be extinguished, the inventor has provided a selection valve corresponding to each section to be extinguished, and a starting gas corresponding to each of the selection valves. Intensive research and analysis were conducted to simplify the fire extinguishing equipment equipped with a container and to realize the highly accurate release of fire extinguishing gas to the necessary areas to be extinguished.

The present inventor believes that providing one or more valves between the container valve of the starting gas container and the selection valve, which requires opening of the selection valve, means that one starting gas container can be It has been learned that this method is effective for opening the selection valve. However, the inventor has determined that merely adopting the above configuration is insufficient. This is because, at the same time, an electrical signal is sent to the valve (for example, a solenoid valve) that requires the selection valve to open, and a starting gas container valve (second If the electrical signal is also sent to the fire extinguishing valve), in the unlikely event that an erroneous electrical signal is sent, there remains the problem of malfunction in which extinguishing gas may be released into an unnecessary area to be extinguished. It is.

Therefore, the present inventor discovered that an electric signal for one or more valves, which are provided between the container valve of the starting gas container and the selection valve, and which requires opening of the selection valve, is incorrectly sent to the starting gas container. In order to prevent the container valve of a gas container from opening, it has been discovered that a new mechanical operation that does not rely on human hands can be introduced. As a result, the present inventor has found that at least a portion of each of the above-mentioned technical problems can be solved. In addition, the present invention simplifies fire extinguishing equipment or fire prevention equipment (hereinafter collectively referred to as "fire extinguishing equipment" in this application) and reduces equipment costs, and allows one starting gas container to be used for multiple selection valves. We also learned that the valve can be opened with high accuracy. The present invention was created based on the above-mentioned viewpoints and ideas.

One electric wire connection mechanism of the present invention connects a first electric wire for transmitting an electric signal and starting gas to a first valve corresponding to a selection valve for selectively supplying extinguishing gas to a section to be extinguished. A second valve included in the startup gas container accommodated therein is provided with a second electric wire for transmitting the electric signal. In addition, this electric wire connection mechanism utilizes the movement of the first valve from the closed state to the open state to open and close the first valve when the first valve receives the above-mentioned electric signal. By mechanically connecting the electric wire and the aforementioned second electric wire, the aforementioned electric signal is transmitted to the aforementioned second valve.

According to this electric wire connection mechanism, if the first electric wire and the second electric wire are not connected, the starting gas in the starting gas container will not be supplied to the selection valve even if the first valve receives an electric signal. Opening of the selection valve due to malfunction can be prevented with high accuracy. In other words, only after the first electric wire and the second electric wire are connected by this electric wire connection mechanism, the starting gas to be released from the starting gas container is selected via the first valve opened by an electric signal. Can be supplied to the valve. As a result, this wire connection mechanism can contribute to the realization of highly reliable discharge of extinguishing gas to the required area to be extinguished.

In addition, in this fire extinguishing equipment, the above-mentioned first electric wire and the above-mentioned second electric wire are connected, so that the above-mentioned electric signal is transmitted to the above-mentioned second valve via the first electric wire and the above-mentioned second electric wire. The second valve is opened.

According to this fire extinguishing equipment, if the electric wire connection mechanism does not connect the first electric wire and the second electric wire, the starting gas in the starting gas container will not work even if the first valve receives an electric signal from the sensing section. Since it is not supplied to the selection valve, opening of the selection valve due to malfunction can be prevented with high accuracy. In other words, only after the first electric wire and the second electric wire are connected by the electric wire connection mechanism, the starting gas released from the starting gas container is transferred to the selection valve via the first valve opened by an electric signal. can be supplied to As a result, it is possible to simplify the fire extinguishing equipment and reduce equipment costs, and one starting gas container can open a plurality of selection valves with high accuracy.

According to this method of connecting electric wires, unless the first electric wire and the second electric wire are connected, the starting gas in the starting gas container will not be supplied to the selection valve even if the first valve receives an electric signal. , it is possible to highly accurately prevent the selection valve from opening due to malfunction. In other words, only after the first electric wire and the second electric wire are connected by this electric wire connection mechanism, the starting gas to be released from the starting gas container is selected via the first valve opened by an electric signal. Can be supplied to the valve. As a result, this wire connection mechanism can contribute to the realization of highly reliable discharge of extinguishing gas to the required area to be extinguished.

Further, one fire extinguishing method of the present invention includes a sensing step of sensing heat and/or smoke, and an electric signal emitted by the sensing step is selectively applied to a section to be extinguished with extinguishing gas through a first electric wire. a first transmission step of transmitting the signal to the first valve corresponding to the selection valve for supplying the first valve; and a first transmission step of opening and closing the first valve from the closed state when the first valve receives the above-mentioned electric signal. an electric wire connecting step of connecting the first electric wire and a second electric wire for transmitting the gas to a second valve provided in a starting gas container containing the starting gas by utilizing the movement to the first state; a second transmission step of transmitting the electric signal to the second valve through the first electric wire and the second electric wire by connecting the first electric wire and the second electric wire; and the second valve. a starting gas release step in which the starting gas is opened to release the starting gas, and the starting gas is used to open the aforementioned selection valve, and a corresponding extinguishing gas is accommodated in the selection valve.

According to this fire extinguishing method, if the first electric wire and the second electric wire are not connected in the electric wire connection process, the first valve will not be able to start the starting gas container if it only receives the electric signal emitted in the sensing process. Since gas is not supplied to the selection valve, opening of the selection valve due to malfunction can be prevented with high accuracy.

(2) Extinguishing agent container 60 containing extinguishing gas
(3) A selection valve 70 corresponding to the container valve of the extinguishing agent container 60 for selectively supplying extinguishing gas to the section to be extinguished
(4) One starting gas container 40 containing starting gas for opening the container valve of the extinguishing agent container 60
(5) A first valve 22 of the wire connection mechanism including a switch 20, which will be described later, corresponds to the selection valve 70 and opens when receiving an electric signal emitted from the sensing section 12.
(6) First electric wire 33 for transmitting the electric signal to the first valve 22
(7) Second electric wires 34a, 34b for transmitting the electric signal to the second valve 52 included in the starting gas container 40
(8) When the first valve 22 receives the electric signal, the first electric wire 33 and the second electric wires 34a, 34b are connected by using the movement of the valve that opens and closes the first valve 22 from the closed state to the open state. Wire connection mechanism to connect

In addition, the fire extinguishing equipment 100 connects the first electric wire 33 and the second electric wires 34a, 34b using the above-mentioned electric wire connection mechanism, so that the fire extinguishing equipment 100 can The above-mentioned electric signal is transmitted to the second valve 52, and the second valve 52 is opened. Here, both the first valve 22 and the second valve 52 of this embodiment are valves whose opening and closing can be controlled by receiving the electric signal. Note that a typical example of the first valve 22 is a solenoid valve using an electromagnetic actuator (solenoid) or an electric valve using a motor. Further, a typical example of the second valve 52 is a solenoid valve.

Furthermore, focusing on the wire connection mechanism of this embodiment, the wire connection mechanism has the following configurations (a) to (b) in more detail.
(a) A first electric wire 33 for transmitting an electrical signal to the above-mentioned first valve 22 corresponding to the selection valve 70 for selectively supplying extinguishing gas to the section to be extinguished.
(b) A second electric wire 34a for transmitting an electric signal to a second valve 52 included in the starting gas container 40 that contains starting gas.

In addition, the electric wire connection mechanism of the present embodiment has the above-described configurations (a) and (b), so that the valve that opens and closes the first valve 22 when the first valve 22 receives an electric signal. The electric signal is transmitted to the second valve 52 by mechanically connecting the first electric wire 33 and the second electric wire 34a using the movement from the closed state to the open state.

In the fire extinguishing equipment 100 having the above configuration, as shown in FIGS. 1 to 3, when the sensing unit 12 arranged in at least one fire extinguishing target section senses heat and/or smoke (sensing process), the sensing A first valve 22 for transmitting the electrical signal emitted by the section 12 or the sensing step via the first electric wire 33 to the first valve 22 corresponding to the selection valve 70 for selectively supplying extinguishing gas to the section to be extinguished. A transmission process takes place. Specifically, the electric signal is transmitted to the first valve 22 provided in the wire connection mechanism via the first electric wire 33 that continues through the control panel 14 (first transmission step) (FIG. 2 and (1), (2) in Figure 3).

When the electrical signal is transmitted to the solenoid 22a of the first valve 22, the solenoid 22a connects the valve body 22b to the valve body 22b as shown in the example of the wire connection mechanism in FIGS. 4(a) and (b). ) in the M direction. Then, the movable part 22c integrated with the valve body 22b will also move in the M direction. This operation of the valve body 22b causes the first valve 22 to open.

Note that the movable portion 22c has a length and thickness such that it can be moved in the M direction in FIG. 4A or the opposite direction by a human hand or by hanging it on a finger. Therefore, the movable part 22c can be moved manually depending on the situation.

On the other hand, the example of the wire connection mechanism of this embodiment includes a switch 20 having a main body part 20a and a trigger part 20b. The trigger part 20b has a structure in which one end connected to the main body part 20a is a fixed point, and the other end can pivot. Further, the other end is configured to electrically connect the first electric wire 33 and the second electric wire 34a, which is not shown in FIG. 4, by contacting the main body portion 20a.

In this embodiment, the electric wire connection mechanism of the above-mentioned example is used, and when the first valve 22 receives the electric signal, the movement of the valve from the closed state to the open state is used to open and close the first valve 22. Then, an electric wire connecting step is performed to connect the first electric wire 33 and the second electric wires 34a and 34b for transmitting the gas to the second valve 52 included in the starting gas container 40 that accommodates the starting gas.

Specifically, when the electric signal is not applied to the solenoid 22a, the other end of the trigger portion 20b is maintained separated from the main body portion 20a (FIGS. 4(a) and 4(b)). On the other hand, when the electric signal is applied to the solenoid 22a, as shown in FIG. 4(c), the movable part 22c moves in the M direction together with the valve body 22b to mechanically pivot the other end. As a result, the other end comes into contact with the main body portion 20a. As a result, the first electric wire 33 and the second electric wire 34a are electrically connected via the solenoid 22a. Note that "S" in FIG. 3 and FIGS. 5 to 7 described later is an expression for making the switch 20 easier to visually understand.

In the present embodiment, the switch 20 electrically connects the first electric wire 33 and the second electric wire 34a by pivoting the trigger part 20b, but an example of the electric wire connection mechanism is shown in FIG. Not limited to structure.

After the electric wire connecting step, in this embodiment, the first electric wire 33 and the second electric wire are connected, so that the electric signal is transmitted to the second valve via the first electric wire 33 and the second electric wires 34a and 34b. A second transmission step of transmitting to 52 is performed.

Specifically, when the first electric wire 33 and the second electric wire 34a are mechanically connected by the switch 20 and the electric signal from the sensing section 12 is transmitted from the first electric wire 33 to the second electric wire 34a, as shown in FIG. 1 to 3, the electric signal is transmitted to the second valve 52 provided in the starting gas container 40 via the second electric wire 34a, the control panel 14, and the second electric wire 34b (see FIG. and (3), (4) in Figure 3).

When the electric signal is transmitted to the second valve 52, the second valve opens, so that a starting gas (for example, CO ₂ gas (carbon dioxide gas or carbon dioxide gas) or N 2 gas (for example, CO 2 gas (carbon dioxide gas or carbon dioxide gas) or N ₂ gas ( Nitrogen gas)) is released (startup gas release step).

After the start-up gas release step, the start-up gas is used to open the selection valve 70, and the container valve of the extinguishing agent container 60 containing the extinguishing gas corresponding to the selection valve 70 is opened to extinguish the fire. A fire extinguishing gas release step is performed to release the gas. In this embodiment, the pressure of the starting gas released from the extinguishing agent container 60 is adjusted by a pressure reducing device or a pressure reducing valve using a known adjustment spring (not shown), but this will be described in this embodiment and later. The pressure reducing devices or pressure reducing valves employed in other embodiments are not limited to the above-mentioned examples.

Specifically, since the first valve 22 is already open when the electric signal is transmitted to the solenoid 22a of the one or more first valves 22, the released starting gas The gas passes through the first valve 22 from the gas pipe 50 . Then, the selection valve 70 corresponding to the first valve 22 is opened by the pressure of the starting gas ((5) in FIGS. 2 and 3).

In addition, when the starting gas passes through the first gas pipe 50 via the first valve 22 ((5) in FIGS. 2 and 3), the starting gas is supplied to the selection valve 70 using the annular valve 64. Only the container valve of the fire extinguishing agent container 60 is opened. As a result, the extinguishing gas released from the extinguishing agent container 60 with the container valve opened passes through the selection valve 70 via the collecting pipe 62 and the second gas piping 66a, and then passes through the selection valve 70 through the third gas piping 66b. The fire is extinguished by being emitted from the injection part 94 provided with a nozzle hole ((6) and (7) in FIGS. 2 and 3). Note that each of the extinguishing agent containers 60 is equipped with a known pressure reducing device, so that after the gas on the supply side is depressurized to a predetermined pressure required as extinguishing gas, it is sent to the injection section via the third gas pipe 66b. 94 is a preferred embodiment.

As described above, according to the electric wire connection mechanism of this embodiment, unless the first electric wire 33 and the second electric wires 34a, 34b are connected, the first valve 22 will not be able to connect the starting gas container just by receiving an electric signal. 40 starting gases will not be supplied to the selection valve 70. This can highly accurately prevent the selection valve 70 from opening due to malfunction. In other words, only when the first electric wire 33 and the second electric wires 34a, 34b are connected by this electric wire connection mechanism, the starting gas released from the starting gas container 40 is transferred to the first valve opened by the electric signal. 22 to the selection valve 70. As a result, this wire connection mechanism can contribute to the realization of highly reliable discharge of extinguishing gas to the required area to be extinguished.

In addition, according to the fire extinguishing equipment 100 of this embodiment, if the wire connection mechanism of this embodiment does not connect the first wire 33 and the second wires 34a, 34b, the first valve 22 prevents the The starting gas in the starting gas container 40 is not supplied to the selection valve 70 only by receiving the electric signal. As a result, opening of the selection valve 70 due to malfunction can be prevented with high accuracy.

In other words, according to the fire extinguishing equipment 100 of this embodiment, the starting gas is discharged from the starting gas container 40 for the first time when the first electric wire 33 and the second electric wires 34a, 34b are connected by the electric wire connection mechanism of this embodiment. gas can be supplied to the selection valve 70 via the first valve 22 which is opened by an electric signal. As a result, it is possible to simplify the fire extinguishing equipment 100 and reduce equipment costs, and even if one starting gas container 40 is responsible for supplying starting gas to a plurality of selection valves 70, the necessary Therefore, the selection valve 70 can be opened with high accuracy.

<Second embodiment>

As a result, the extinguishing gas released from the extinguishing agent container 60 passes through the selection valve 70 via the collecting pipe 62 and the second gas pipe 66a, and then passes through the third gas pipe 66b to the nozzle hole. The fire is extinguished by being emitted from the injection section 94 provided with the fire.

As mentioned above, arranging the constant pressure gas container 68 for adjusting the pressure of the starting gas between the starting gas container 40 and the container valve of the fire extinguishing agent container 60 ensures stable supply of gas on the supply side. This is a preferable embodiment from the viewpoint of realizing a safe pressure. More specifically, by using the first electric motor 22, the constant pressure gas container 68 can be moved to the downstream side of the starting gas container 40, so more stable constant pressure gas can be sent to the injection section. , is a preferred embodiment from the viewpoint of being able to radiate a constant flow rate to the fire extinguishing target section.

As a result, the extinguishing gas released from the extinguishing agent container 60 with the container valve opened passes through the selection valve 70 via the collecting pipe 62 and the second gas piping 66a, and then passes through the selection valve 70 through the third gas piping 66b. The fire is extinguished by being emitted from the injection section 94 provided with a nozzle hole.

As a result, in the fire extinguishing equipment 300 equipped with the wire connection mechanism according to the present embodiment, a constant pressure gas container 368 for adjusting the pressure of the starting gas is provided between the starting gas container 40 and the container valve of the fire extinguishing agent container 60. This arrangement is a preferable aspect from the viewpoint of realizing stable and safe pressure of the gas on the supply side.

Further, according to the fire extinguishing equipment 300 of this embodiment, if the wire connection mechanism of this embodiment does not connect the first wire 33 and the second wires 34a, 34b, the first valve 22 The starting gas in the starting gas container 40 is not supplied to the selection valve 70 just by receiving the signal. As a result, opening of the selection valve 70 due to malfunction can be prevented with high accuracy.

In other words, according to the fire extinguishing equipment 300 of this embodiment, the starting gas is discharged from the starting gas container 40 only after the first electric wire 33 and the second electric wires 34a, 34b are connected by the electric wire connection mechanism of this embodiment. gas can be supplied to the selection valve 70 via the first valve 22 which is opened by an electric signal. As a result, it is possible to simplify the fire extinguishing equipment 300 and reduce the equipment cost, and even if one starting gas container 40 is responsible for supplying starting gas to a plurality of selection valves 70, the necessary Therefore, the selection valve 70 can be opened with high accuracy.

<Fourth embodiment>
In the fire extinguishing equipment 400 equipped with the wire connection mechanism in this embodiment, the starting gas container 40 is not provided, except that the constant pressure gas container 368 described in the third embodiment also serves as the starting gas container. This is the same as the fire extinguishing equipment 300 of the third embodiment. Therefore, explanations that overlap with those of the first to third embodiments may be omitted.

FIG. 7 is a system diagram of fire extinguishing equipment 400 including the wire connection mechanism in this embodiment.

As shown in FIG. 7, like the fire extinguishing equipment 100 or the fire extinguishing equipment 300, the fire extinguishing equipment 400 in this embodiment also has only one constant pressure gas container 368 that serves as a starting gas container. Further, like the fire extinguishing equipment 100 or the fire extinguishing equipment 300, the fire extinguishing equipment 400 also includes a first valve 22 including a switch 20 corresponding to the selection valve 70, which opens when receiving an electric signal emitted from the sensing section 12. When the first valve 22 receives the electric signal, the first electric wire 33 and the second electric wires 34a, 34b are connected by using the movement of the valve that opens and closes the first valve 22 from the closed state to the open state. Equipped with a wire connection mechanism for connection.

Therefore, according to the wire connection mechanism of the fire extinguishing equipment 400 of this embodiment, when the electric signal emitted from the sensing section 12 is transmitted to the solenoid (not shown) of the first valve 22, the solenoid The first valve 22 opens by moving the body. On the other hand, similarly to the first embodiment, the switch 20 electrically connects the first electric wire 33 and the second electric wire 34a by pivoting a trigger portion (not shown) as the valve body of the first valve 22 moves. let As a result, the electrical signal is transmitted to the second valve 52 for opening and closing the constant pressure gas container 368 via the switch 20 and the second electric wires 34a, 34b.

When the electrical signal is transmitted to the second valve 52, the constant pressure gas container 368 opens, and the gas (for example, _N2 gas (nitrogen Gas)) is released as starting gas.

Then, the starting gas passes through the first gas pipe 50 and opens the container valve of the fire extinguishant container 60. As a result, the extinguishing gas released from the extinguishing agent container 60 with the container valve opened passes through the selection valve 70 via the collecting pipe 62 and the second gas piping 66a, and then passes through the selection valve 70 through the third gas piping 66b. The fire is extinguished by being emitted from the injection section 94 provided with a nozzle hole.

Therefore, the fact that the fire extinguishing equipment 400 equipped with the wire connection mechanism in this embodiment includes the constant pressure gas container 368 that also serves as a starting gas container realizes stable and safe pressure of the gas on the supply side. From this point of view, this is a preferred embodiment.

Further, according to the fire extinguishing equipment 400 of this embodiment, if the wire connection mechanism of this embodiment does not connect the first wire 33 and the second wires 34a, 34b, the first valve 22 Simply receiving the signal does not supply the starting gas from the constant pressure gas container 368, which also serves as a starting gas container, to the selection valve 70. As a result, opening of the selection valve 70 due to malfunction can be prevented with high accuracy.

In other words, according to the fire extinguishing equipment 400 of this embodiment, it is not until the first electric wire 33 and the second electric wires 34a, 34b are connected by the electric wire connection mechanism of this embodiment that the constant pressure that also serves as a starting gas container is established. The starting gas released from the gas container 368 can be supplied to the selection valve 70 via the first valve 22 opened by an electric signal. As a result, the fire extinguishing equipment 400 is simplified and equipment costs are reduced, and even if the constant pressure gas container 368 also serves as a single starting gas container, it is responsible for supplying starting gas to the plurality of selection valves 70. Even if this happens, the required opening of the selection valve 70 can be realized with high accuracy.

As stated above, the disclosure of each of the above-mentioned embodiments is described for explanation of those embodiments, and is not described for limiting the present invention. In addition, modifications that fall within the scope of the invention, including other combinations of the embodiments, are also within the scope of the claims.
