Description

  The present invention relates to a pump monitoring device and pump equipment (pump station) including the monitoring device.

  There is a pump facility as a means to prevent flooding when the river water level rises due to heavy rain. As shown in FIG. 9, this pump facility is arranged adjacent to the tributary, and when the water level of the tributary rises, the pump 2 is activated to force a part of the tributary water flow to the main river. Transport. The pump facility includes a suction water tank 1 into which a part of the water of the tributary flows, a pump 2 for discharging the water that flows into the suction water tank 1, a discharge water tank 3 for storing water discharged from the pump 2, and a discharge water tank And a drainage lock 4 connecting the 3 outlets to the main river. At the position where the tributary joins the main river, a natural flow down gate 11 is provided, and when there is no rain and the water level of the main river is lower than the water level of the tributary, the natural flow down gate 11 is open. is there.

  In such a pump facility, as shown in FIG. 10, the pump 2 and its driving machine 5 are installed in the pump chamber 6. The drive machine 5 is comprised from an electric motor or an engine etc., and is connected with the pump 2 via the reduction gear which is not shown in figure. The pump chamber 6 is also provided with a power distribution board 7, an operation panel 8, and the like, and the pump 2 is operated by operating the drive unit 5 through the power distribution board 7 and the operation panel 8. Further, a monitoring room 9 may be provided adjacent to the pump room 6. In the monitoring room 9, management and monitoring of a plurality of pumps 2 are performed. In addition, when a plurality of pump facilities as shown in FIG. 9 are installed, the monitoring room 12 that integrates and manages the plurality of pump facilities may be provided in a remote place different from the installation place of the monitoring room 9. is there.

  The operation panel 8 disposed in the pump chamber 6 receives and displays a failure signal sent from a measuring instrument provided in the pump 2 and an instrumentation signal sent from a water level gauge, a pressure gauge, and an ammeter. Have the ability to These failure signals, instrumentation signals, and the like are similarly transmitted to the monitoring room 9 and the monitoring room 12 located in a remote place. The monitoring rooms 9 and 12 are provided with display equipment (for example, a display panel, a display table, or a display) 10 for displaying these signals, so that the operator can check the state of the pump equipment. . The display facility 10 receives the signal via the relay control panel 13.

  There is a case where a monitoring room 9 provided in the pump station has a window, and the operation status of the pump 2 can be directly visually monitored from this window, but usually, the operation status of the pump 2 by looking at the display facility 10, that is, The operation state such as whether the pump 2 is in normal operation or in failure, and state values such as the current value and pressure value of the pump 2 can be grasped in the monitoring room 9. However, since such a display facility 10 has almost the same display configuration as the operation panel 8 provided in the pump chamber 6, it is very uneconomical in terms of cost.

  Moreover, since the signal sent to the display facility 10 is the number of pumps 2, the number of display points of the display facility 10 is enormous and a large facility is required. There will be a corresponding number of communication lines laid from the pump room to the monitoring room. For this reason, there are problems such as an increase in cost due to an increase in the number of maintenance targets and complicated wiring and signal confirmation during construction of the pump equipment. Further, when the pump facility is refurbished to improve the function, it is necessary to renovate not only the operation panel 8 but also the display facility 10. As a result, the scope of the renovation work has become wider, making it difficult to refurbish for the purpose of improving the function from the economical aspect. In particular, when a plurality of pump facilities are managed collectively in the monitoring room 12 located in a remote place, it is necessary to repair the display facility 10 in the monitoring room 12 every time the pump facility is repaired, which increases the cost. .

  If there is a worker in the pump facility, when an abnormality occurs in the water level of the river, etc., the situation should be accurately grasped by the worker actually going to the suction water tank 1, the discharge water tank 3, or the pump chamber 6. Can do. However, in the monitoring room 12 at a remote location, the worker must determine the status of the pump facility based only on the display of the display facility 10. For this reason, when the abnormal signal shown on the display facility 10 is simply due to signal failure (noise, interface failure, etc.), the worker may make a wrong determination. For this reason, there was a problem in the reliability of monitoring and management of the pump equipment.

  In the pump facility as a countermeasure against the flooding of the river shown in FIG. 9, it is usual that no workers are stationed at normal times when the pump is not required to operate. In the event of an emergency such as a rise in the water level of a river, workers rushed from nearby to operate the pump equipment. When an earthquake, tsunami, or the like occurs, the worker cannot reliably check the safety of the pump facility using only the display facility 10 described above. From the monitoring room 12 provided in a remote place, there was a problem that not only the safety of the pump facility but also the safety of the worker could not be sufficiently confirmed.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic plan view of a pump facility according to an embodiment of the present invention. FIG. 2 is a schematic diagram of the equipment configuration of the pump equipment. In addition, although embodiment of the pump installation demonstrated below is a pump installation for transferring the water of a river, this invention is not limited to this embodiment. As shown in FIG. 1, the pump facility is discharged from a suction water tank 1 into which a part of water flowing through a tributary flows, a plurality of pumps 2 for transferring water flowing into the suction water tank 1, and the pump 2. A discharge water tank 3 for storing water and a drainage lock 4 for discharging water in the discharge water tank 3 to the main river. The pump 2 sucks the water in the suction water tank 1 and pressurizes it, and then discharges it to the discharge water tank 3. The water in the discharge water tank 3 is discharged from the drainage gate 4 to the main river. At the position where the tributary joins the main river, a natural flow gate 11 is provided, and when there is no rainfall and the water level of the main river is lower than the water level of the tributary, this natural flow gate 11 is open.

  As shown in FIG. 2, the pump 2 of this pump facility is connected to a driving machine 5 for driving the pump 2. The drive machine 5 is composed of an electric motor and an engine, and is connected to the pump 2 via the speed reducer 14. In the pump chamber 6 in which the pump 2 and the drive machine 5 are arranged, a power distribution board 7 and an operation panel 8 are arranged. An individual operation panel 15 is provided for each of the plurality of pumps 2 installed. Further, in the pump facility, a collective display panel 20 having a plurality of display units for displaying measured values of measuring instruments attached to the pump 2 and failure signals of the pump 2 is disposed in the pump chamber 6.

  FIG. 3 shows an example of an enlarged view of the collective display board 20 when five pumps 2 are arranged. The collective display panel 20 has five current display units 21 (upper) for displaying the current values for driving the pump 2 and five pressure display units 22 (lower) for displaying the discharge pressure values of the pump 2. doing. These five current display units 21 and pressure display units 22 are provided for each of the five pumps 2. A water level display unit 26 is provided on the left side of the current display unit 21 and the pressure display unit 22, and the tributary water level is shown in the upper stage and the main river level is shown in the lower stage. Only one of the current display unit 21 and the pressure display unit 22 may be arranged. Furthermore, you may provide the temperature display part which displays the temperature value of the pump 2 and / or the drive machine 5. FIG. Such a display unit for displaying measured values such as current, pressure, water level, and temperature indicating the operation status of the pump 2 is hereinafter referred to as an operation display unit. In addition, as shown in the figure, an analog display using an indicator needle is preferable for the measured values such as current and pressure, but a digital display can also be used.

  Below the operation display units 21, 22, and 26, a failure display unit 23 that indicates a failure of the pump 2 is disposed. In the example shown here, six types of failure display sections 23 are provided for each of the five pumps 2. That is, in FIG. 3, “ground fault” represents the leakage of the pump 2, and “overload” represents the overload of the pump 2. “PF blown” represents a fuse disconnection of the pump 2, and “low water absorption level” represents that the water absorption level of the pump 2 has fallen below an alarm value. “Falling water” indicates that the siphon in the pump casing of the pump 2 constituted by the impeller casing, the suspension pipe, the discharge curved pipe, and the like has been destroyed, and “starting congestion” indicates that the starting process of the pump 2 is somehow Indicates that it cannot proceed due to a cause. When a failure occurs in the pump equipment, the corresponding failure display unit 23 is turned on or blinked to notify the occurrence of the failure and the location of the failure.

  A monitoring camera 30 for photographing such a collective display board 20 is provided in the pump chamber 6. The monitoring camera 30 is configured to acquire a color moving image of the collective display board 20. The video of the collective display panel 20 taken by the monitoring camera 30 is displayed on the monitor 40 installed in the monitoring chamber 9 outside the pump chamber 6 via the video controller 35 (see FIG. 2). When another monitoring room 12 is provided in a remote place away from the installation site of the pump facility, the monitor 40 arranged in the monitoring room 12 also has the collective display panel 20 captured by the monitoring camera 30. The video can be sent via the video controller 35. When the monitoring room 9 is not provided and only the monitoring room 12 is provided at a remote place, the video of the collective display panel 20 is sent only to the monitor 40 of the monitoring room 12.

  With such a configuration, a display facility (FIG. 9) for displaying a huge number of measurement values and signals in the monitoring room 9 which is a local monitoring room and the monitoring room 12 which is a central monitoring room provided far away. Therefore, the installation cost can be greatly reduced and the maintenance cost can be kept low. Moreover, it has been necessary to connect all wiring for transmitting measurement signals such as pressure values and current values in addition to the failure signal and operation signal of the pump 2 to the display equipment 10 used conventionally. According to the configuration of the present embodiment, only the wiring for transmitting the video signal output from the monitoring camera 30 needs to be connected to the monitor 40, so that the installation work cost can be greatly reduced. In addition, when the pump equipment is repaired, the monitoring rooms 9 and 12 do not need to be repaired, so the equipment can be repaired in a short period of time and at a low cost. Furthermore, since the number of signal wirings can be greatly reduced, there is almost no signal failure such as noise or interface failure. Therefore, it is possible to improve the monitoring reliability of the pump equipment. Moreover, if the monitoring camera 30 is rotated, it is possible to monitor the inside of the pump chamber 6 in which the pump 2 is arranged, and it is possible to confirm the overturning / destruction of the pump equipment during a natural disaster.

  The monitoring camera 30 may be fixedly installed so as to photograph the collective display board 20, but as described above, the monitoring camera 30 may be configured to be rotatable. This is because when the monitoring camera 30 is made rotatable, the overall situation inside the pump chamber 6 can be confirmed. In particular, if the monitoring camera 30 is provided with a zoom function, the internal monitoring of the pump chamber 6 can be made easier and more reliable. Note that a camera that can be rotated may have a preset function that automatically rotates to a preset video position.

  In addition to the monitoring camera 30 that images the collective display panel 20, a monitoring camera 31 that images the pump 2 in the pump chamber 6, a monitoring camera 32 that images the water level of the suction tank 1, and a monitoring camera that images the drainage lock 4 33 may be further provided. These monitoring cameras 31, 32, and 33 are used for confirming the operation of the pump equipment and for confirming the safety of the suction side and the discharge side of the pump 2. In this case, it is preferable to further provide monitors for the monitoring cameras 31, 32, and 33 in the monitoring rooms 9 and 12 in addition to the monitor 40. The screen of the monitor 40 for the monitoring camera 30 may be divided so that images sent from the monitoring cameras 31, 32, and 33 are displayed on the monitor 40.

  An indicator indicating the water level of the suction water tank 1 may be installed on the wall surface of the suction water tank 1 so that the monitoring camera 32 can photograph the indicator and quantitatively check the water level value. Similarly, an indicator indicating the water level of the discharge water tank 3 may be installed adjacent to the drainage lock 4 and the monitoring camera 33 may photograph the indicator. Since the water levels on the suction side and the discharge side are important as operation management items of the pump 2, water level meters are installed in the suction water tank 1 and the discharge water tank 3, and the measured values are converted into signals, and the monitoring room 9 , 12. However, if the water level gauge breaks down, there is a risk that the wrong water level value will reach the workers and as a result, the pump will be operated incorrectly. Then, if the indicator which shows the water level of the suction water tank 1 and the discharge water tank 3 which were mentioned above is image | photographed with the monitoring cameras 32 and 33, respectively, an operator can grasp | ascertain an exact water level.

  When the pump 2 fails, the collective display panel 20 may be configured to send a collective failure signal of the pump 2 to the monitoring rooms 9 and 12. By adopting such a configuration that sends the minimum number of signal points, when the monitor 40 receives an alarm, the worker can immediately confirm through the monitor 40 what kind of failure has occurred. Yes, quick and reliable response is possible. Instead of sending a collective failure signal, a function capable of detecting the color change of the collective display board 20 is added to the monitor 40, and the monitor 40 gives an alarm when the color of the collective display board 20 on the monitor 40 changes. You may comprise so that it may alert.

  As shown in FIG. 2, it is preferable to provide a recording unit 45 that records video captured by the surveillance camera 30. Furthermore, it is preferable to record the video of the above-described monitoring cameras 31, 32, and 33 in the recording unit 45. The recording unit 45 is a hard disk drive, for example, and may be connected to the monitor 40 or the video controller 35 or may be built in the monitor 40 or the video controller 35. The recording unit 45 is configured to receive a failure signal of the pump 2 sent from the collective display board 20, and is configured to receive a video of a predetermined time before and after receiving the failure signal in response to the failure signal. May be.

  In conventional pump equipment, in addition to failure signals, measured values such as current values and pressure values are stored at intervals of several seconds and used as failure data for trend analysis. However, at the time of a failure that causes a transitional state change, it is difficult to grasp a sufficient state because an instantaneous abnormal value cannot be captured. As a result, the cause of the failure may not be identified. According to the present embodiment, when a failure occurs in the pump 2, it is possible to confirm the movement of a minute time interval such as a pressure value and a current value from the recorded video. Furthermore, based on the images taken by the monitoring cameras 31, 32, 33 in addition to the images taken by the monitoring camera 30, the overall condition including the overall pump facility status (for example, the discharge amount of the pump 2) and the water level status are included. Determination can be made, and the cause of the failure can be specified more reliably.

  Next, a modified example of the collective display board 20 will be described with reference to FIG. FIG. 4 is a diagram showing another example of the collective display panel 20 captured by the monitoring camera 30. As shown in FIG. As shown in FIG. 4, the collective display panel 20 is provided with a character display unit 24, and the failure content is displayed on the character display unit 24. The example shown in FIG. 4 indicates a failure in which the No. 1 pump has fallen, that is, the siphon of the No. 1 pump has been destroyed. By providing such a character display section 24, the visibility of the failure on the monitor 40 is increased, and the worker can surely understand the content of the failure, so that the pump equipment can be restored early. Become. In a state where no failure has occurred, for example, by displaying state values such as the water level of the suction water tank 1 and / or the discharge water tank 3, the pump facility can be managed smoothly.

  Next, imaging in the pump chamber 6 by the monitoring camera 30 will be described with reference to FIG. FIG. 5 is a schematic diagram showing that the monitoring camera 30 is photographing the inside of the pump chamber 6. In the present embodiment, the monitoring camera 30 is configured to be rotatable so that the monitoring camera 30 that captures the collective display panel 20 can capture the entire interior of the pump chamber 6. By enabling not only the collective display panel 20 but also the entire interior of the pump chamber 6 to be photographed, the entire pump facility can be monitored. In addition, since the work site is projected by the monitoring camera 30, it is possible to directly confirm visually that the worker is working, which is useful for confirming the safety of the worker.

  The surveillance camera 30 configured to be rotatable may have a thermographic function. Alternatively, a thermographic camera may be provided in the pump chamber 6 separately from the monitoring camera 30. The monitoring camera 30 or the thermographic camera having a thermographic function acquires a thermographic image indicating the surface temperature of a device such as the pump 2 and transmits it to the monitor 40. The worker can grasp the temperature state of the equipment such as the pump 2 from the thermographic image displayed on the monitor 40. This thermographic video (moving image) is also stored in the recording unit 45 described above. When a failure occurs, the device and the part where the failure occurs usually generate heat. For example, in the case of a bearing failure, frictional heat is generated by rubbing between the bearing and the shaft. If the thermographic image of the device in the pump chamber 6 is recorded as described above, it is possible to help identify the location of the failure by analyzing the thermographic image. In addition, by periodically recording and observing thermographic images, it is possible to accurately grasp the deterioration tendency of the device.

  As shown in FIG. 5, a monitoring camera 30 or a monitoring camera 31 having a thermography function, or a monitor 41 for displaying a thermographic image taken by a thermography camera is provided in a monitoring room 9 and / or a monitoring room separately from the monitor 40. 12 may be provided. Instead of providing the monitor 41, the monitor 40 or the video controller 35 can be provided with a changeover switch capable of switching between a normal captured video and a thermographic video.

  When the inside of the pump chamber 6 is photographed by the monitoring camera 30 or the monitoring camera 31, as shown in FIG. 5, an indicator lamp 35 indicating the operation state of the corresponding pump 2 is provided near each of the plurality of pumps 2. Is preferred. The illustrated indicator lamp 35 is a three-color lamp having different colors such as a red lamp, a yellow lamp, and a green lamp. The red lamp indicates that the pump 2 has failed, and the yellow lamp indicates that the pump 2 is starting. The green lamp indicates that the pump 2 is operating normally. By visually checking the indicator lamp 35 through the monitor 40, the operator can immediately determine the operating state of the pump 2, and the operating state of the pump 2 can also be determined from the images taken by the monitoring camera 30 and the monitoring camera 31. Can be confirmed. Furthermore, even an operator who is unfamiliar with the work site can quickly identify the location where the failure occurs and can speed up the recovery from the failure. The indicator lamp is not limited to the example of the three-color lamp shown in the figure, and may be a two-color lamp that indicates a normal operation and a failure, or a one-color lamp that indicates only a failure.

  When the monitoring camera 30 or the monitoring camera 31 is used to photograph the inside of the pump chamber 6, as shown in FIG. 6, it is preferable to provide a marker 34a that changes its pattern when the main shaft 34 rotates on the outer peripheral surface of the main shaft 34 of the pump 2. . In the event of a disaster such as an earthquake, the pump equipment may need to be shut down urgently. In such a case, it is possible to easily determine whether or not the main shaft 34 is stopped from the change in the pattern of the marker 34a appearing on the video captured by the monitoring camera 30 or the monitoring camera 31. Note that a non-contact dynamo light used in a bicycle or the like may be provided instead of the marker to emit light during driving.

  Next, a modified example of the collective display board 20 will be described with reference to FIG. FIG. 7 is a view showing still another example of the collective display board 20 captured by the monitoring camera 30. In FIG. As shown in FIG. 7, the collective display panel 20 is provided with a start progress state display unit 25 that displays the start progress state of the pump 2. At the left end of the starting progress state display unit 25, a number display unit for displaying the number of the pump that is currently started is disposed.

  The pump 2 is started according to the start command. When the drive machine 5 is composed of an engine, first, the operation of the engine lubricating oil pump is started. At the same time, the intake valve 36 disposed in the vacuum pipe connected to the vacuum pump 50 for making the inside of the pump casing vacuum is opened (see FIG. 5). Further, a drain valve (not shown) is closed. When the drain valve is closed and the intake valve 36 is opened, the vacuum pump 50 is started. When the vacuum pump 50 is started, the inside of the pump casing becomes negative pressure, and the pump casing is filled with water in the suction water tank 1. When the inside of the pump casing is full, the intake valve 36 is closed, the vacuum pump 50 is stopped, and the drive unit 5 is started on the condition that the engine lubricating oil pressure is normal, and the pump 2 is operated. Be started.

  According to the progress of the starting operation of the pump 2, “start command”, “initial lubricating oil pump operation”, “intake valve open”, “drain valve close”, “vacuum pump operation”, “full water”, “intake valve close” The lamps for “vacuum pump stop”, “lubricating oil pressure normal”, and “main pump operation” are lit or blinking. It may take 5 to 10 minutes for the pump 2 to reach a steady operation. Thus, if the collective display panel 20 displays how much the starting operation of the pump 2 is currently progressing, the worker can It is possible to reliably grasp the progress status by simply viewing the video on the monitor 40, and to prevent a delay in drainage due to a start abnormality.

  In most cases, the pump 2 breaks down at the time of start-up, and it can be confirmed from which lamp is lit or blinking in which process the failure has occurred. Therefore, it is possible to grasp the occurrence of a failure and the location of the failure early and reliably, and it is possible to take measures early. In addition, when the start of the pump 2 is not progressing normally, that is, when each step of the start operation of the pump 2 does not shift to the next step within a predetermined set time, “ The “Start traffic jam” lamp is lit or flashing.

  The embodiment of the present invention has been described so far, but the monitoring camera 30 that captures images of the collective display panel 20 and the pump chamber 6 may break down. As a countermeasure in this case, two monitoring cameras 30 capable of photographing the inside of the collective display panel 20 and the pump chamber 6 may be provided. By duplicating the monitoring camera 30 in this way, even if one of the monitoring cameras breaks down, the collective display board 20 can be photographed by the other monitoring camera, so the reliability of the monitoring device is improved. improves. For example, as shown in FIG. 8, two monitoring cameras 30 configured to be rotatable are provided in the pump chamber 6, and both monitoring cameras 30 are arranged at positions where the collective display panel 20 can be photographed. It is preferable to do this.

  It is also conceivable that the monitor 40 that projects the video sent from the surveillance camera 30 breaks down. As a countermeasure in this case, it is conceivable that the video controller 35 (see FIG. 2) has a function of communicating to the outside. As the communication function of the video controller 35, the Internet, a wired LAN, a wireless LAN, or the like can be considered. If the video controller 35 is provided with an external communication function in this manner, the video taken by the monitoring camera 30 can be displayed on a monitor or a mobile terminal (tablet terminal) prepared separately. Monitoring can be continued. In addition, since it is possible to monitor with a mobile terminal with such a configuration, workers moving to the pump station can obtain the operating status and failure status of the pump station with the mobile terminal. Equipment operability is improved.

  Furthermore, it is preferable to use an LED lamp for the failure display portion 23 of the collective display panel 20 for the reason that there is almost no fear of lamp breakage and energy saving. However, it is also conceivable that the LED lamp is cut off because an abnormally high voltage is applied to the collective display panel 20 due to lightning. As a measure against lamp burnout, the monitoring rooms 9 and 12 can be provided with a lamp test button (not shown) for confirming that the LED lamp of the failure display unit 23 is normally lit. When all the LED lamps in the failure display section 23 are normal, all the LED lamps are turned on when the lamp test button is pressed. Therefore, by pressing the lamp test button, it is possible to immediately identify the LED lamp causing the lamp breakage from the image that the monitoring camera 30 displays on the monitor 40.

  The lamp test button is connected to the collective display panel 20 with a signal line. Instead of such a wired system, a wireless system in which an electric signal of the lamp test button is transmitted to the collective display panel 20 by radio waves may be employed. When the wireless system is used, although it is not necessary to pull out the signal line from the monitoring rooms 9 and 12, the lamp of the failure display unit 23 may be lit due to the influence of noise or the like, so the wired system is preferable. .

  If a temporary power failure occurs due to some sort of failure or lightning, the lamp indicating the failure will turn off, and it will not emit light even if power is restored (the signal itself disappears at the time of the power failure, and the light emitting contact is also restored. Because). Therefore, it is preferable to provide a target type failure indicator (falling type failure indicator) in the collective display panel 20. Since the target type failure indicator can maintain and continue the failure indication mechanically, it leads to improvement in reliability. As such a target type failure display, a commercially available one can be used.
