Description

[Technical Field]

[0001] The present invention relates to a safety device for fire extinguishing equipment, and more particularly to a safety device for fire extinguishing equipment that extinguishes a fire by activating the fire extinguishing equipment and releasing a gas-based fire extinguishing agent such as carbon dioxide into the protected compartment when a fire breaks out within the protected compartment. More specifically, the present invention relates to a safety device for fire extinguishing equipment that prevents activation due to erroneous operation of the fire extinguishing equipment activation button provided on an operation box installed within or near the protected compartment. [Background technology]

[0002] In the past, there have been cases where the incorrect operation of the fire extinguishing equipment activation button on the control box installed in or near the protected area has resulted in the release of gas-based fire extinguishing agents such as carbon dioxide into the protected area, and if there are people in the protected area, this has led to personal injury accidents.

[0003] Since such human errors (mistakes caused by human misperception or malfunction) cannot be completely eliminated, it is important to take preventive measures to prevent accidents on the fire extinguishing equipment side.

[0004] As an example of a preventive measure, a safety device for a fire extinguishing facility has been proposed (see, for example, Patent Document 1). This fire extinguishing equipment safety device is provided with a fire extinguishing operation restriction means including a timer that restricts the transmission of a start command signal to the starting device even if the start operation button of the fire extinguishing equipment is operated until a predetermined time has passed since the door for opening and closing the operation box is opened.As a result, even if the door for opening and closing the operation box is mistaken for the operation box of another equipment or is opened as a prank when there is no fire and the start operation button of the operation box is pressed, the operation restriction action of the fire extinguishing operation restriction means including the timer has the effect of preventing the start command signal from being instantly transmitted to the starting device.

FIG. DETAILED DESCRIPTION OF THE INVENTION

[0018] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a safety device for a fire extinguishing facility according to the present invention will now be described with reference to the accompanying drawings. [Example]

[0019] A first embodiment of the safety device for a fire extinguishing facility according to the present invention will be described. As shown in Figures 1 and 2, this safety device for fire extinguishing equipment is equipped with an opening / closing door 11 and an operation box 1 which, when the opening / closing door 11 is opened, has a start-up operation button ("release" button) 12 which issues a start-up command to the starting device of the fire extinguishing equipment and an emergency stop operation button ("stop" button) 13 which cancels the start-up command, and which extinguishes a fire by releasing a gas-based fire extinguishing agent such as carbon dioxide into a protected area. An operation restriction means is provided so that when the start-up operation button 12 is pressed twice or pressed for a long time, a start-up command is issued to the starting device of the fire extinguishing equipment.

[0020] In this case, when the start-up operation button 12 is pressed (during pre-startup; this also applies when it is pressed twice or pressed for a long time, as well as when it is pressed once for a short time), an alarm means can be provided to notify the operator that the start-up operation button 12 is being operated (a means for displaying a warning message or audio message such as "You are operating the start-up operation button which issues a start-up command to the start-up device of the fire extinguishing equipment.").

[0021] In addition, the operation restriction means can be configured to issue a start command to the start-up device of the fire extinguishing equipment when the start-up operation button 12 is pressed after the notification means has notified the operator that the start-up operation button 12 has been operated.

[0022] FIG. 3 shows the operational flow when manually starting up this fire extinguishing system equipped with a safety device. First, an operator who discovers and confirms a fire (step S0) opens the door 11 for opening and closing the operation box 1 (step S1), which then outputs an evacuation alarm such as a voice alarm (step S2), and the alarm means is activated, outputting an audio message through the speaker, such as, "This is the activation device for the fire extinguishing equipment. Please check the situation inside the protected area and then press the activation operation button 12 twice or press and hold it down" (step S3). Then, when the door 11 for opening and closing the operation box 1 is opened, a message such as "When the start operation button is pressed twice or pressed for a long time, a start command will be issued to the start device of the fire extinguishing equipment" will be displayed at an appropriate location inside the operation box 1 as necessary.

[0023] The operator presses the start-up operation button 12 to issue a start-up command to the start-up device of the fire extinguishing equipment (step S4). However, an operation restriction means is provided that issues a start-up command to the start-up device of the fire extinguishing equipment when the start-up operation button 12 is pressed twice or pressed for a long time, so that the start-up of the fire extinguishing equipment due to an erroneous operation of the start-up operation button 12 can be restricted. When the start-up operation button 12 is pressed (at the time of pre-startup, this also applies when the button is pressed twice or pressed for a long time, or when the button is pressed once for a short time), a voice message such as "The start-up operation button that issues a start command to the start-up device of the fire extinguishing equipment is being operated" is output from the notification means that notifies the operator that the start-up operation button 12 is being operated through the speaker. The data is input (step S5). Then, the operation control means determines whether the startup operation button 12 has been pressed twice or for a long time (step S6), and if it has been pressed twice or for a long time (more specifically, if it has been pressed twice or for a long time after step S5), a voice message such as "Startup preparation for the fire extinguishing equipment has been completed" is output through the speaker as a startup preparation completion message (step S7). On the other hand, if the start-up operation button 12 is pressed once for a short time, the operation restriction means determines that the start-up operation button 12 has been pressed incorrectly, and returns to step S3 without issuing a start-up command to the start-up device of the fire extinguishing equipment.

[0024] When the start-up operation button 12 is pressed twice or pressed for a long time, the delay timer starts counting time at the same time as the pressing operation (step S8). During the time until this delay timer times out (usually several tens of seconds), it is determined whether the emergency stop operation button 13 has been pressed (step S9), and if it has been pressed, the start-up command is cancelled to the start-up device of the fire extinguishing equipment, and start-up is stopped (step S10). On the other hand, if no operation is performed, after the delay timer times out (step S11), the control unit issues a start-up command to the fire extinguishing equipment's start-up device, the container valve opens, and a gas-based fire extinguishing agent such as carbon dioxide is released into the protected area (step S12). [Example]

[0025] Next, a second embodiment of the safety device for fire extinguishing equipment according to the present invention will be described. As shown in Figure 4, this safety device for fire extinguishing equipment is a safety device for fire extinguishing equipment that extinguishes fires by releasing a gas-based fire extinguishing agent such as carbon dioxide into a protected area, and is equipped with an operation box 1 that has an opening / closing door 11 and, when the opening / closing door 11 is opened, a start operation button 12 that issues a start command to the fire extinguishing equipment's start device and an emergency stop operation button 13 that cancels the start command.It is equipped with a determination means for determining whether or not there is a person in the protected area (for example, a human detection means such as a human sensor or camera, entry / exit recorder, etc.), and when the determination means determines that there is a person, an alarm means 14 that alerts the presence of a person in the protected area, for example, a means for displaying a warning message such as "There is a person in the area to be extinguished" by using an LCD or lighting, which is installed in an appropriate location inside the operation box 1 when the opening / closing door 11 is opened (or in an appropriate location around the operation box 1), or a similar voice message is output through a speaker. This makes it possible to restrict the activation of fire extinguishing equipment when there are people in the protected area.

[0026] In this case, a switching means may be provided that turns on / off the function of disabling the operation of the start-up operation button when the determination by the determining means is "yes." [Example]

[0027] Next, a third embodiment of the safety device for a fire extinguishing facility according to the present invention will be described. As shown in Figures 1 and 2, this safety device for fire extinguishing equipment is equipped with an opening / closing door 11 and an operation box 1 having, inside the opening / closing door 11, a start-up operation button 12 for issuing a start-up command to the starting device of the fire extinguishing equipment and an emergency stop operation button 13 for canceling the start-up command, and it relates to a safety device for fire extinguishing equipment that extinguishes fires by releasing a gas-based fire extinguishing agent such as carbon dioxide into a protected area.When the opening / closing door 11 is opened (step S1 in Figure 3), after a delay time (e.g., 5 to 10 seconds) preset by a delay timer, an alarm means (e.g., a warning display, an audio display, etc.) is provided to alarm that this is an operation device that issues a start-up command to the starting device of the fire extinguishing equipment (step S3 in Figure 3). This makes it possible to prevent the start of the fire extinguishing equipment from being caused by mistakenly operating the start operation button 12 due to startle. [Example]

[0028] Next, a fourth embodiment of the safety device for a fire extinguishing facility according to the present invention will be described. As shown in Figures 1 and 2, this safety device for fire extinguishing equipment is equipped with an opening / closing door 11 and an operation box 1 having, inside the opening / closing door 11, a start operation button 12 for issuing a start command to the starting device of the fire extinguishing equipment and an emergency stop operation button 13 for canceling the start command, and which extinguishes fires by releasing a gas-based fire extinguishing agent such as carbon dioxide into a protected area. When the opening / closing door 11 is open, an alarm means (warning display, audio display) is provided to alarm the operating status of the fire extinguishing equipment. This allows the operating status of the fire extinguishing equipment to be constantly monitored, and the activation of the fire extinguishing equipment to be restricted as necessary. [Example]

[0029] Next, a fourth embodiment of the safety device for a fire extinguishing facility according to the present invention will be described. As shown in Figure 5, this safety device for fire extinguishing equipment is equipped with an opening / closing door 11 and an operation box 1 which, when the opening / closing door 11 is opened, has a start operation button 12 which issues a start command to the starting device of the fire extinguishing equipment and an emergency stop operation button 13 which cancels the start command, and which extinguishes a fire by releasing a gas-based fire extinguishing agent such as carbon dioxide into a protected area, and the start operation button 12 is positioned lower than the emergency stop operation button 13. This prevents the start of the fire extinguishing equipment from being accidentally operated by reflexively operating the start operation button 12.

[0030] The safety device for fire extinguishing equipment of the present invention has been described above based on several embodiments, but the present invention is not limited to the configurations described in the above embodiments, and by appropriately combining the configurations described in each embodiment, the configuration can be changed as appropriate within the scope of the purpose, such as restricting activation due to erroneous operation of the activation operation button from various angles in response to human error caused by various factors. [Industrial Applicability]

[0031] The safety device for fire extinguishing equipment of the present invention can regulate from multiple angles the start-up of the fire extinguishing equipment due to erroneous operation of the start-up operation button, etc., in response to human error caused by various factors that cannot be prevented by conventional safety devices for fire extinguishing equipment. Therefore, the safety device for fire extinguishing equipment can be suitably used as a safety device for fire extinguishing equipment that extinguishes fires by releasing a gas-based fire extinguishing agent such as carbon dioxide into a protected compartment.
