Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention provides a method for backing up fire extinguishing equipment by operating pump equipment of fire extinguishing equipment for other purposes when sufficient pump performance cannot be obtained from the pump equipment of fire extinguishing equipment that has started up due to a fire. This invention relates to backup equipment for fire extinguishing equipment.

[Prior Art] Conventionally, fire extinguishing equipment for buildings such as buildings has been provided with fire extinguishing equipment for multiple uses, such as sprinkler fire extinguishing equipment, foam fire extinguishing equipment, indoor fire hydrant equipment, etc., and each fire extinguishing equipment Each has its own pump equipment.

When a fire occurs, pump equipment of fire extinguishing equipment corresponding to the location of the fire is activated. That is, the sprinkler pump equipment is automatically started in response to a drop in the pressure inside the pipe due to the operation of the sprinkler, and if a fire breaks out in a parking lot where a foam fire extinguishing head is installed, for example, the foam fire extinguishing pump equipment is activated. Furthermore, when using indoor fire hydrants,
The indoor fire hydrant pump equipment is activated by the operation of the lifeguard.

By the way, in the case of such fire extinguishing equipment, the fire extinguishing pump equipment is always maintained in an operable state through periodic inspections, etc., but even if the pump equipment of a specific fire extinguishing equipment is activated in the event of a fire, the pump may not start. It is expected that there may be cases where the fire extinguishing equipment cannot function normally, so an equipment configuration may be considered in which multiple fire extinguishing equipment are connected by piping so that they can back up each other.

[Problem to be solved by the invention] However, if the pump cannot be started normally in the event of a fire, the pump equipment for backup can be started because the failure to start the pump can be immediately recognized. Even if the pumping is carried out normally, if the planned pump performance is not being fully demonstrated, it is difficult to judge whether sufficient pump performance is being obtained or not, so it is necessary to effectively use the backup equipment. There was a problem in that the fire extinguishing ability was reduced because the pump could not be utilized and sufficient pump performance could not be obtained, and by the time the pump performance was noticed it was too late.

The present invention was made in view of these conventional problems, and provides a backup system for fire extinguishing equipment that can be mutually backed up between multiple fire extinguishing equipment for other uses so that sufficient pump performance can always be achieved as planned. The purpose is to provide equipment.

[Means for Solving the Problems] In order to achieve this object, the present invention provides pump equipment that is provided for each type of fire extinguishing equipment for different purposes, such as sprinkler pump equipment, foam fire extinguishing pump equipment, indoor fire hydrant pump equipment, etc. In the equipped fire extinguishing equipment, there is a measuring means that measures various data of the pump equipment of the fire extinguishing equipment that is activated in the event of a fire, and a system that determines whether the measured data from the measuring means is within the rated range to ensure sufficient pump performance. A judgment means for judging whether sufficient pump performance has been obtained, and when the judgment means judges that sufficient pump performance has not been obtained, a judgment means for determining whether sufficient pump performance has been obtained, and a judgment means for determining whether sufficient pump performance has been obtained, A control means that controls the opening of a valve provided in the backup piping between the two and starts the pump equipment of the fire extinguishing equipment for other purposes for backup;
It is characterized by having the following.

Further, the control means is characterized in that means is provided for setting the backup priority order for each fire extinguishing equipment in advance.

[Function] In the backup device for fire extinguishing equipment of the present invention having such a configuration, even if the pump equipment of a specific fire extinguishing equipment is normally activated in the event of a fire, sufficient pre-scheduled pump performance is maintained. In the case of an abnormal situation in which this is not possible, the abnormal state is judged from the measurement data, and the valve installed in the backup piping between the fire extinguishing equipment for other uses is opened, and then the pump equipment of the fire extinguishing equipment for other uses for backup is removed. is activated to compensate for the decline in the performance of the original fire pump equipment, and even if the pump performance is reduced, it achieves the same fire extinguishing performance as if the pump performance was always sufficient as planned, and prevents fires from occurring. It is possible to respond quickly and appropriately.

In particular, the data measurement means of the automatic inspection device installed in the fire extinguishing equipment can be used as is as a means of measuring various data for determining pump performance, so when used in conjunction with automatic inspection equipment, the equipment can be simpler. The configuration allows backup control to maintain pump performance.

Further, each of the fire pumps 2a to 2c of each pump facility is provided with pump suction pressure sensors 24a to 24c and pump discharge pressure sensors 25a to 25c for detecting pump suction pressure and pump discharge pressure.

FIG. 1 is a block diagram showing an embodiment of the present invention intended for the fire extinguishing equipment shown in FIG.

In FIG. 1, 30 is a fire extinguishing equipment automatic inspection relay board, which functions as a measuring means for measuring various data in each fire pump equipment in the backup device of the present invention.

For the fire extinguishing equipment automatic inspection relay panel 30, for example, taking the foam fire extinguishing pump equipment 100 as an example, a test flow rate flow switch 32a that detects the flow rate flowing into the test piping 22a shown in FIG.
Pump suction pressure sensor 24a that detects the pump suction pressure of a, pump discharge pressure sensor 25a that detects the pump discharge pressure, motor rotation sensor 34a that detects the rotation speed of the electric motor 1a, and motor voltage sensor 36a that detects the voltage of the electric motor 1a. , a motor current sensor 38a that detects the current of the motor 1a is provided, and detection signals from these various sensors are given to the fire extinguishing equipment automatic inspection relay board 30.

The sensors for measuring various data in the sprinkler pump equipment 200 and the indoor fire hydrant pump equipment 300 are also the same as those in the foam fire extinguishing pump equipment 100. Further, from the fire extinguishing equipment automatic inspection relay board 32, a control signal is given to the electric valves 23a to 23c for pump performance testing provided in the test piping 22a to 22c of each pump equipment, and furthermore, the backup piping equipment 12 in FIG. A control signal is also given to backup motor-operated valves 7, 15a to 15c provided in FIG.

Furthermore, pump control panels 40a to 40c are installed near the installation locations of the fire pumps 2a to 2c of each pump equipment.
are provided, and these pump control panels 40a~
The fire extinguishing equipment automatic inspection relay board 30 is also connected to signal line 40c. In addition, in the case of actual equipment, the motor voltage sensors 36a to 36c and the current sensor 38
a to 38c are incorporated into pump control panels 40a to 40c.

On the other hand, the central monitoring room is provided with an automatic inspection control panel 42, which instructs the fire equipment automatic inspection relay panel 30 to perform automatic inspection control at predetermined time intervals, for example, and performs automatic inspection control. Inspection data obtained from this process will be collected to check the equipment status.

Furthermore, in this embodiment, the fire extinguishing equipment automatic inspection relay panel 30 determines whether the measurement data for each pump equipment obtained from each sensor is within the rated range, and determines whether sufficient pump performance is obtained. It has a function as a judgment means, and sends the judgment results to the central automatic inspection management board 42. Automatic inspection management panel 42
is a backup display 44 that indicates that the pump should be backed up based on the judgment result when the fire extinguishing equipment automatic inspection relay board 30 determines that sufficient pump performance cannot be obtained; A backup switch 46 is provided for an operator to issue a backup control command to the fire extinguishing equipment automatic inspection relay board 30, and a recovery switch 47 is provided for restoring the backup state when the pump is stopped after backup.

As a result, when a backup control signal based on the operation of the backup switch 46 is sent from the automatic inspection management panel 42 to the automatic fire extinguishing equipment inspection relay board 30, the automatic fire extinguishing equipment inspection relay panel 30 switches to the fire extinguishing equipment set in advance for backup. Backup electric valves 15a~ installed in backup piping between fire extinguishing equipment having pump equipment that has already been activated
15c and also performs backup control to start the backup pump equipment. For this purpose, the fire extinguishing equipment automatic inspection relay board 30 is equipped with measuring means and measurement data for measuring various data of each fire extinguishing pump equipment. In addition to the function of determining whether sufficient pump performance can be obtained by determining whether the pump performance is within the rated range, the pump also functions as a backup control means.

Next, the control processing of the backup device of the present invention will be explained with reference to the operational flow diagram of FIG.

As an explanation of the control process shown in FIG. 3, assume that, for example, a fire occurs at a sprinkler head installation location, the sprinkler pump equipment 200 is activated, and the indoor fire hydrant pump equipment 300 is preset as backup equipment for the sprinkler pump equipment 200. do.

In FIG. 3, the presence or absence of a fire is first monitored in step S1, and if a fire occurs at the sprinkler installation location, the process proceeds to step S2 and the sprinkler pump 2b is activated. Specifically, the pressure inside the main pipe 4b decreases due to the operation of the sprinkler head, and at the same time, the tank pressure in the pressure tank 11 decreases, so the pressure switch installed in the pressure tank 11 detects the pressure decrease and activates the electric motor 1b. The sprinkler pump 2b is started.

When the sprinkler pump 2b is started in step S2, the process proceeds to step S3, where the automatic fire extinguishing equipment inspection relay board 30 shown in FIG. is measured, and in step S4 it is determined whether the measured data is within a preset data rating range, and it is determined whether sufficient pump performance can be obtained. If abnormal data that does not allow sufficient pump performance is generated by comparing the measured data and the rated range data in step S4, the abnormal data is included in the step S4 along with the measured data.
In S5, the data is sent to the central automatic inspection management board 42, and upon receiving this abnormality data, the automatic inspection management board 42 displays a backup request on the backup display 44. Of course, at the same time as the backup request is displayed, a backup warning is issued to the operator by a buzzer, bell, etc. Based on this backup request display, the operator switches the backup switch 46.
When the button is pressed, a backup signal is transmitted from the automatic inspection management panel 42 to the automatic inspection relay panel 30 for fire extinguishing equipment.

In step S6, it is checked whether or not a backup signal has been received from the automatic inspection control panel 42, and when the backup signal is received, step S7 is executed.
Go to and start the backup pump. That is,
The electric motor 1c of the indoor fire hydrant pump equipment 300 starts the fire hydrant pump 2c. Then step
At S8, the electric valves 15a and 15c in the backup piping equipment 12 shown in FIG. The pump performance of the sprinkler pump 2b is compensated for due to communication and a decrease in pump performance. As a result, water for fire extinguishing is supplied to the main pipe 4b of the sprinkler pump equipment 200 by the parallel operation of the sprinkler pump 2b and the fire hydrant pump 2c, and as a result, sufficient pump performance is obtained, so that the activated sprinkler head Sufficient watering will be carried out.

Subsequently, once the fire has been extinguished, the pump is stopped by going to the pump control panel, so it is determined in step S9 that the pump should be stopped, and the process proceeds to step S10. At this time, when the operator operates the recovery switch 47 in response to the stoppage of the fire pump, a recovery signal is received in step S10, and the recovery process in step S10 is performed. That is, the electric backup valve 15
c, 15a and disconnect the main pipes 4b and 4c,
The process returns to the fire monitoring state of step S1 again.

On the other hand, if measurement data that corresponds to the rated value is obtained in step S4 and it is determined that sufficient pump performance can be maintained, the measurement data is sent to the central automatic inspection control panel 42 in step S12, and the pump is inspected in step S13. Steps S3 to S4 are repeated without performing backup operation until it is determined that the pump has stopped, and when it is determined that the pump has stopped, the process returns to the fire monitoring state of step S1.

Note that the control process shown in FIG. 3 takes as an example the case where the fire hydrant pump equipment 300 backs up the sprinkler pump equipment 200 that has been activated in the event of a fire, but the same applies to the activation of pumps in other equipment in the event of a fire. However, when it is determined that sufficient pump performance cannot be obtained, backup is performed in the same manner by starting other preset pump equipment.

When backing up priorities is set in advance for each fire extinguishing equipment, it is desirable to set them in order of decreasing probability of a fire occurring at the same time. In other words, since foam fire extinguishing equipment is usually installed in underground parking lots, sprinkler fire extinguishing equipment, and indoor fire hydrant equipment are installed in offices, etc., a fire can occur simultaneously in places where these foam fire extinguishing equipment, sprinkler fire extinguishing equipment, and indoor fire hydrant equipment are installed. Since there is little chance of this occurring, for example, it is desirable to back up sprinkler fire extinguishing equipment in the order of priority: foam fire extinguishing equipment, then indoor fire hydrants.

However, if a fire is detected in the equipment being backed up during backup, backup control will be stopped and the fire will be extinguished in the own equipment. In addition, a priority is set in advance for each piece of equipment, and if the priority of the equipment being backed up is higher than the priority of the equipment being backed up, a fire will be detected in the equipment being backed up. However, the backup may continue as is.

In addition, although the above-mentioned embodiment takes as an example the case where the backup device of the present invention is applied to a fire extinguishing equipment equipped with an automatic inspection device, the backup device of the present invention can be used alone without being used together with an automatic inspection device. Of course, it may also be provided in the fire extinguishing equipment.

Furthermore, backup of the fire pump equipment may be performed by pump equipment other than fire extinguishing equipment, such as spring water pump equipment.

[Effects of the Invention] As explained above, according to the present invention, it is determined whether various measurement data of fire pump equipment activated in the event of a fire is within the rated range, and it is determined that sufficient pump performance cannot be obtained. When a fire occurs, the valve installed in the backup piping between the fire extinguishing equipment for other uses is opened and the pump equipment for the backup fire extinguishing equipment for other uses is activated, resulting in a reduction in pump performance. Even if there is an abnormality that is difficult to detect, backup operation can be performed reliably, sufficient pump performance can be obtained, and the reliability of the fire extinguishing equipment can be greatly improved.

Furthermore, by applying the backup device of the present invention to fire extinguishing equipment equipped with an automatic inspection device, it is possible to measure various data for determining pump performance by directly using the measuring means of the automatic inspection device. By using it together with an automatic inspection device, a simpler backup device can be realized.

In addition, the priority order of fire extinguishing equipment to be backed up is
Since the settings are set in order of decreasing probability of a fire occurring at the same time, backup operations can be performed more reliably and fire extinguishing operations can be carried out.
