Description

The present invention relates to a drainage pipe clogging monitoring device and a drainage pipe clogging monitoring system, particularly to monitor the degree of clogging of a horizontal pipe.

For example, drainage from a restaurant in a building such as a shopping mall is sent from a drainage pipe in the store to a vertical pipe (main pipe) of the shopping mall through a drainage pipe and a drainage horizontal branch pipe, and then goes outdoors. It is discharged.

However, in restaurants that use a relatively large amount of oils and fats, there is a relatively high possibility that the drain pipe will be clogged. When the degree of clogging becomes severe, the drainage that has flowed from the drainage basin into the drainage horizontal branch pipe may flow back without being discharged from the vertical pipe and flood the inside of the store. In order to eliminate such a situation, it is necessary to clean the drain pipe before it becomes severely clogged.

However, since the drainage pipe is buried in the floor of a building or the like, it is not possible to easily check the degree of clogging in the drainage pipe. It is also possible to clean the product regularly, but the degree of clogging varies depending on the store, so if it is not so clogged, it will be a wasteful cleaning work. In addition, waste may occur in terms of cost. On the contrary, if the interval for performing the cleaning work is too large, the backflow of drainage may occur as described above.

An object of the present invention is to make it possible to easily monitor the degree of clogging of a horizontal pipe without visual inspection.

The drainage pipe clogging monitoring device according to the present invention has a tubular frame portion fixed to the inner surface of the horizontal pipe in the vicinity of the drainage inflow side of the horizontal pipe, and backflow from the drainage outflow side of the horizontal pipe to the position of the frame portion.

It is characterized by including an air through port corresponding to the upper side in the frame portion divided by the main body portion.

Further, the air pressure measuring means attached to the air through port is provided, and the transmitting means transmits data on the wind pressure measured by the wind pressure measuring means to the central monitoring device.

In addition, the side surface of the drainage outlet side of the transverse pipe of the front Stories body portion, the orientation of the drainage outlet side of the transverse pipe, and a plurality of recesses in which the water sensor is attached to each are provided.

It is a conceptual diagram which shows the main part of the drainage piping facility installed in a building in this embodiment. It is a perspective view of the drainage pipe clogging monitoring device in this embodiment. It is a figure which shows the block structure of the drainage pipe clogging monitoring system in this embodiment. It is a figure which shows an example of the display of the data received from the drainage pipe clogging monitoring device in this embodiment.

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a concept showing a main part of a drainage piping facility installed in a building such as a shopping mall for discharging the wastewater from the drainage facility 1 of a restaurant in the shopping mall to the outside. It is a figure. FIG. 1 shows a drainage piping facility including a miscellaneous drainage pipe 2, a drainage basin (collection basin) 3, a drainage trap elbow 4, a drainage horizontal branch pipe 5, and a vertical pipe 6. The drainage discharged from the drainage facility 1 is assumed to be drainage discharged from a sink in a cooking room or a drainage port on the floor. The drainage may include oils and fats that cause clogging of the drainage pipe, food residue, powder, and the like (hereinafter, collectively referred to as "oils and fats").

As shown by an arrow in FIG. 1, the drainage discharged from the drainage facility 1 passes through the miscellaneous drainage pipe 2 and is stored in the drainage basin 3, and passes through the drainage trap elbow 4, the drainage horizontal branch pipe 5, and the vertical pipe 6. Is discharged to the outdoors. When the water level of the drainage in the drainage basin 3 exceeds the lower surface of the drainage horizontal branch pipe 5, the drainage stored in the drainage basin 3 is automatically discharged to the drainage horizontal branch pipe 5.

The drainage pipe clogging monitoring device 7 in the present embodiment is attached near the inlet side of the drainage lateral branch pipe 5 (the inflow side from the drainage basin 3 of the drainage), and monitors the clogging of the drainage lateral branch pipe 5. The drainage horizontal branch pipe 5 is a form of a horizontal pipe. Since the drain trap elbow 4 is detachably connected to the drain horizontal branch pipe 5, the drain pipe clogging monitoring device 7 can be easily attached to the drain horizontal branch pipe 5 by removing the drain trap elbow 4. It is also possible to remove the drainage pipe clogging monitoring device 7 from the drainage lateral branch pipe 5 for cleaning.

FIG. 2 is a perspective view of the drainage pipe clogging monitoring device 7 according to the present embodiment. The drainage pipe clogging monitoring device 7 has a tubular shape according to the shape of the inner diameter of the drainage horizontal branch pipe 5, and a rubber packing 72 is attached to the entire outer circumference of the main body frame 71 forming the tubular shape. The frame portion of the drainage pipe clogging monitoring device 7 is formed of a main body frame 71 and a rubber packing 72, and the entire outer circumference of the rubber packing 72 comes into contact with the inner surface of the drainage horizontal branch pipe 5 to allow the drainage horizontal branch pipe to be drained from the drainage basin 3. The drainage flowing into the drainage pipe 5 passes through the drainage pipe clogging monitoring device 7. The drainage pipe clogging monitoring device 7 may be detachably fixed to the drainage horizontal branch pipe 5 by screwing or the like. Alternatively, it may be welded and fixed so that it cannot be attached or detached.

A main body 73 is provided in the central portion of the main body frame 71 along the length direction of the drain pipe clogging monitoring device 7 (the direction in which the drainage flows, which is indicated by the arrow A in FIG. 2). Since the main body portion 73 is in contact with the left inner surface and the right inner surface of the main body frame 71, the inside of the main body frame 71 is divided into upper and lower parts. The opening corresponding to the upper side formed by being divided into upper and lower parts is an air through port 74 through which air flows. The opening corresponding to the lower side formed by being divided into upper and lower parts is a drainage through port 75, through which drainage flows.

The main body 73 is formed with a certain width (thickness) in the vertical direction as illustrated in FIG. On the side surface of the drainage outflow side (outlet side of the drainage lateral branch pipe 5) formed by the width, a plurality of water detection sensors are provided as water level detecting means for detecting the water level of the drainage flowing back from the drainage outflow side. In the case of the embodiment, the two water detection sensors 76a and 76b are provided side by side in the vertical direction. The water detection sensors 76a and 76b are attached to the recesses 77a and 77b provided on the side surface of the main body 73, respectively. In the following description, when it is not necessary to distinguish the water detection sensors 76a and 76b from each other, they are collectively referred to as "water detection sensor 76". The same applies to the recess 77. Since the water detection sensor 76 detects the drainage that has flowed back, the water detection sensor 76 is provided in the recess 77 so as not to detect the drainage that is not backflow, that is, the drainage that flows in the direction of arrow A.

When the drainage horizontal branch pipe 5 is clogged, the drainage that should have flowed out to the vertical pipe 6 through the drainage pipe clogging monitoring device 7 flows back, but the water detection sensor 76b detects the backflowing drainage. Then, it can be seen that the water level in the drainage lateral branch pipe 5 has reached the mounting position of the water detection sensor 76b. Similarly, when the water detection sensor 76a detects the backflow of drainage, it can be seen that the water level in the drainage lateral branch pipe 5 has reached the mounting position of the water detection sensor 76a. In the present embodiment, by providing the plurality of water detection sensors 76 side by side in the vertical direction in this way, the water level in the drainage lateral branch pipe 5 can be detected. In the present embodiment, the water level is detected by using a plurality of water detection sensors 76, but the water level detection means may be formed by using other means such as a water level detection sensor.

Inside the air through port 74, a wind pressure sensor 78 for measuring the wind pressure of the air passing through the air through port 74 is provided.

A communication device 79 is provided inside the main body 73 as a transmission means for transmitting data on the water level detected by the water detection sensor 76 and data on the wind pressure measured by the wind pressure sensor 78 to the central monitoring device. There is.

FIG. 3 is a diagram showing a block configuration of a drainage pipe clogging monitoring system having the above-mentioned communication device 79 and a central monitoring device. The communication device 79 has a collection unit 791, a data processing unit 792, and a transmission unit 793. The collection unit 791 collects sensor data from the sensors 76 and 78 via a signal line (not shown) or by wireless communication. The data processing unit 792 converts the collected sensor data into data in a format predetermined with the central monitoring device 10. The transmission unit 793 transmits the data converted by the data processing unit 792 to the central monitoring device 10 by wire or wirelessly.

The communication device 79 includes a computer including a CPU, ROM, RAM, storage, and a network interface. Further, although not shown, the communication device 79 includes a power supply means such as a storage battery for operating the computer.

The central monitoring device 10 is a device that centrally monitors the degree of clogging of drain pipes installed in a building, and is a storage means such as a CPU, ROM, RAM, hard disk drive (HDD), a network interface, and a user interface. This can be realized by a server computer provided with (a display as a display means and a mouse or keyboard as an input means). The central monitoring device 10 includes a receiving unit 11, an analysis processing unit 12, a presenting unit 13, a notification unit 14, a data storage unit 15, and a device master information storage unit 16. The components not used in the description of the present embodiment are omitted from the drawings.

The receiving unit 11 receives the data transmitted from the drainage pipe clogging monitoring device 7 and stores it in the data storage unit 15. The analysis processing unit 12 analyzes the data stored in the data storage unit 15 to generate clogging status information indicating the degree of clogging of the drainage lateral branch pipe 5 to which the drainage pipe clogging monitoring device 7 is attached. The presenting unit 13 presents the clogging status information generated by the analysis processing unit 12 to a user such as an observer by displaying it on a display connected to the central monitoring device 10, for example. The notification unit 14 performs maintenance work on the drainage pipe by providing information on the correspondence to the drainage horizontal branch pipe 5 according to the clogging condition of the drainage horizontal branch pipe 5 that can be predicted from the clogging status information generated by the analysis processing unit 12. Notify workers, etc.

Master information regarding the drainage pipe clogging monitoring device 7 is set and registered in the device master information storage unit 16. The master information includes identification information of the drain pipe clogging monitoring device 7, position information for specifying the mounting position of the drain pipe clogging monitoring device 7, the type of sensor possessed by the drain pipe clogging monitoring device 7, the mounting position of each sensor, and the like. Includes sensor information that depends on the type of sensor. Since the location of the store can be specified from the contract information or the like in the location information, the identification information of the store using the drainage horizontal branch pipe 5 to which the drainage pipe clogging monitoring device 7 is attached may be set. Alternatively, when the arrangement position of the drainage horizontal branch pipe 5 can be specified from the design information of the building or the like, the identification information of the drainage horizontal branch pipe 5 to which the drainage pipe clogging monitoring device 7 is attached may be set. In addition, information that identifies the floor, area, etc. in the building may be set. In the sensor information, for example, in the case of the water detection sensor 76, the mounting position (height) from the lowest point of the drainage horizontal branch pipe 5 (or the drainage pipe clogging monitoring device 7) is set so that the water level can be specified. NS.

Each component 11 to 14 in the central monitoring device 10 is realized by a cooperative operation of a computer forming the central monitoring device 10 and a program operated by a CPU mounted on the computer. Further, each of the storage units 15 and 16 is realized by the HDD mounted on the central monitoring device 10. Alternatively, RAM or an external storage means may be used via the network.

Further, the program used in the present embodiment can be provided not only by communication means but also by storing it in a computer-readable recording medium such as a CD-ROM or a USB memory. The programs provided by the communication means and the recording medium are installed in the computer, and various processes are realized by sequentially executing the programs by the CPU of the computer.

Next, the operation in the present embodiment will be described.

As described above, the drainage discharged from the drainage facility 1 is discharged to the outside through the miscellaneous drainage pipe 2, the drainage basin 3, the drainage trap elbow 4, the drainage horizontal branch pipe 5, and the vertical pipe 6. Although the drainage horizontal branch pipe 5 is slightly inclined toward the vertical pipe 6, if the drainage contains fats and oils that cause clogging of the drainage pipe, clogging occurs due to the accumulation of fats and oils. Can be done. When the degree of clogging becomes severe, the drainage that flows from the drain trap elbow 4 into the drainage lateral branch pipe 5 and passes through the drainage pipe clogging monitoring device 7 does not flow smoothly to the vertical pipe 6 due to the clogging. , Depending on the situation, it will flow backwards. The drainage that has flowed back returns to the mounting position of the drain pipe clogging monitoring device 7. Then, the water detection sensor 76b outputs a water detection signal when it detects the drainage that has flowed back.

By the way, when a large amount of drainage flows from the miscellaneous drainage pipe 2 into the drainage basin 3 at once, the drainage also flows into the drainage horizontal branch pipe 5 at once. Then, a backflow is likely to occur in the drainage lateral branch pipe 5. On the other hand, when a small amount of drainage flows into the drainage basin 3 from the miscellaneous drainage pipe 2, a small amount of drainage also flows into the drainage horizontal branch pipe 5. Then, even if the drainage lateral branch pipe 5 is clogged, backflow is unlikely to occur. In this way, the water level of the drainage detected by the water detection sensor 76 is affected by the amount of drainage flowing into the drainage lateral branch pipe 5. In the present embodiment, the drainage through port 75 is formed so as to be less affected by the amount of drainage flowing into the drainage horizontal branch pipe 5, and the amount of drainage discharged from the drainage pipe clogging monitoring device 7 is increased. I tried to keep it as constant as possible. This makes it easier to compare changes in the water level over time when recognizing the degree of clogging of the drainage lateral branch pipe 5.

The collection unit 791 of the communication device 79 constantly monitors the outputs from the sensors 76 and 78. Then, when the collecting unit 791 collects the sensor data (water detection signal) output from the water detection sensor 76b, the data processing unit 792 monitors the collected sensor data at the current time (detection time) and the drain pipe clogging. Data on the water level is generated by adding the identification information of the device 7 and the identification information of the water detection sensor 76b that detects the drainage. Then, the transmission unit 793 transmits the data regarding the generated water level to the central monitoring device 10. The same applies when the water detection sensor 76a detects drainage. In the present embodiment, when the water detection sensor 76 detects the drainage, the data is transmitted to the central monitoring device 10, but even when the water detection sensor 76 does not detect the drainage, the data is transmitted to the central monitoring device 10. You may do so.

Further, the collecting unit 791 constantly collects the wind pressure measured by the wind pressure sensor 78, and the data processing unit 792 uses the collected sensor data (wind pressure) at the current time (detection time) and the drain pipe clogging monitoring device 7. The identification information of the wind pressure sensor 78 and the identification information of the wind pressure sensor 78 are added to generate data related to the wind pressure. Then, the transmission unit 793 transmits the data regarding the generated wind pressure to the central monitoring device 10. The data processing unit 792 may set all the collected sensor data as a transmission target, or may set the sensor data collected at a predetermined time interval as a transmission target.

When the receiving unit 11 in the central monitoring device 10 receives the data transmitted from the drainage pipe clogging monitoring device 7 as described above, the receiving unit 11 stores the data in the data storage unit 15.

FIG. 4 is a diagram showing an example of display when the data received from the drain pipe clogging monitoring device 7 is displayed on, for example, a display. The horizontal axis is time. The vertical axis shows the sensor data. In FIG. 4, different types of sensor data are displayed together. The wind pressure shown by the broken line is the wind pressure measured by the wind pressure sensor 78. Further, in FIG. 4, the dotted lines correspond to the water detection sensors 76a and 76b, but the solid line portion on the dotted line corresponds to the water detection signal when it is received.

The manager or the like of the drainage piping facility (hereinafter, “manager”) recognizes the clogging status of the drainage lateral branch pipe 5 by referring to the sensor data displayed in this graph format. For example, in the period when the backflow is detected, the manager tells the length of time that the water detection sensors 76a and 76b detect the drainage, the water detection sensor 76b detects the drainage, and then the water detection sensor 76a discharges the drainage. Time difference until detection, time difference from when water detection sensor 76a stops detecting drainage to when water detection sensor 76b stops detecting drainage, and time from when water detection sensor 76 detects drainage to when it stops detecting Recognize the clogging status of the drainage lateral branch pipe 5 by referring to the degree of change in length and the like.

For example, when the drainage lateral branch pipe 5 becomes severely clogged, it takes time for the drainage detected by the water detection sensor 76 to be drawn. That is, since the water level is difficult to drop, the time for detecting drainage becomes longer. In addition, the time interval for the water detection sensor 76 to detect drainage becomes shorter. Further, when the drainage lateral branch pipe 5 becomes severely clogged, the air also returns to the drainage pipe clogging monitoring device 7, so that the wind pressure tends to increase.

The administrator refers to the relationship between the times of the water detection sensors 76a and 76b when the drainage is detected, the time length and the change in the time interval when the water detection sensor 76 detects the drainage, and the like. Grasp the degree of clogging of the drainage horizontal branch pipe 5.

Further, while the manager recognizes the degree of clogging of the drainage horizontal branch pipe 5 based on experience or the like, the analysis processing unit 12 provides clogging status information indicating the degree of clogging of the drainage horizontal branch pipe 5 based on past results. Generate. The clogging status information includes, for example, a result of predicting a change in the clogging degree of the drainage lateral branch pipe 5 and predicting the timing of inundation of the store. Then, the notification unit 14 generates response information corresponding to the clogging of the drainage lateral branch pipe 5 that can be predicted from the clogging status information, and notifies the worker or the like. The response information includes, for example, that the drainage lateral branch pipe 5, which is recognized from the clogging status information as having a tendency to deteriorate in clogging condition, needs to be cleaned in the near future, although the priority is not high. Alternatively, the drainage lateral branch pipe 5 recognized as being severely clogged may be included in a cleaning plan such as cleaning immediately.

As described above, according to the present embodiment, it is possible to monitor the degree of clogging of the drainage lateral branch pipe 5 without looking into the drainage lateral branch pipe 5. As a result, it is possible to prevent the cleaning from being carried out at an unnecessary timing, and conversely, the store from being flooded due to the delay in cleaning.

In this embodiment, a water detection sensor 76 and a wind pressure sensor 78 are provided, and the degree of clogging of the drainage lateral branch pipe 5 is monitored by each sensor data. The type of sensor is not limited to this, and other types of sensors may be used. For example, a fats and oils sensor may be provided at the drainage through port 75 to collect the ratio of fats and oils contained in the drainage. Further, a barometric pressure sensor may be used instead of the wind pressure sensor 78.

Further, in the present embodiment, two water detection sensors 76a and 76b are provided in the main body 73 in order to detect the water level, but the number of water detection sensors 76a and 76b is not limited to this. The water level may be detected more finely by providing a large number. The mounting positions of the water detection sensors 76a and 76b need not be limited to the main body 73. For example, a plate shape is formed from the main body 73 to at least one of the through ports 74 and 75 (more specifically, the cross section is U-shaped (U-shaped), and the recess faces the drainage outflow side of the drainage lateral branch pipe 5). The water detection sensor 76 may be provided in a recess of the mounting plate so that a large number of water detection sensors 76 can be installed.

Further, in the present embodiment, the drainage pipe clogging monitoring device 7 is attached to the drainage horizontal branch pipe 5 as an example of the horizontal pipe, but it may be attached to another horizontal pipe, for example, the drainage horizontal main pipe or the like.
