Description

[Technical field]

[0001] The present invention relates to a technique for a position adjustment jig capable of adjusting the position of a target device and a method for adjusting the position of a target device. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there is known a technology for a valve that is provided in a pipeline such as a water pipe to open and close a flow path of a fluid (for example, Patent Document 1).

[0003] Since many such valves are installed in a pipeline network, it is believed that by equipping these valves with various sensors (e.g., water quality monitoring devices, flow meters, etc.) to obtain information about the inside of the pipeline (flow path), it will be possible to obtain information about the pipeline network over a wide area and permanently.

[0004] When providing the various sensors described above on a valve, it is necessary to provide not only the sensor but also various devices associated with the sensor (e.g., a battery and a communication terminal device for transmitting the detection results) in a valve box located above the valve.

[0005] However, because the space inside the valve box is limited, there is a concern that if equipment such as a battery is placed inside the valve box, it will be difficult to ensure space for operating and maintaining the valve.

[0006] In addition, since the communication performance (radio wave strength) of a communication terminal device varies depending on the installation environment, it is necessary to install the communication terminal device in an appropriate location where the communication performance can be ensured. Furthermore, the communication performance of the communication terminal device may change after installation due to changes in the surrounding environment.

[0007] For this reason, there is a demand for a technique that can suitably adjust the positions of target devices such as batteries and communication terminal devices. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] In the following description, the directions indicated by the arrows U and D in the drawings are defined as the upward and downward directions, respectively. For the sake of convenience, the drawings show each member in a schematic manner, and the specific shapes, dimensions, etc. are not limited to those shown in the drawings.

[0017] The following describes a position adjustment jig 140 according to one embodiment of the present invention. First, a management system 1 using a valve box 100 in which a position adjustment jig 140 is provided will be described with reference to Figs. 1 and 2.

[0018] The management system 1 manages the fluid in the flow path using a valve 10 described below. More specifically, the management system 1 is installed in a water supply and sewerage facility, and manages the water supplied from a water transmission and distribution facility P and circulating in a water pipe P1 (flow path). For example, the management system 1 can obtain and check information (e.g., water pressure) in the water pipe P1. The management system 1 includes the valve 10, a valve box 100, a communication unit 20, a battery 30, a portable terminal 40, a server 50, and an administrator terminal 60.

[0019] The valve 10 is for controlling the flow of water in the water pipe P1. The valve 10 is composed of a valve (e.g., a gate valve, a butterfly valve, etc.) that opens and closes the flow path in the water pipe P1 with a valve body. The valve 10 is buried in the ground and installed in the middle of the water pipe P1. The valve 10 is equipped with various sensors S (e.g., a pressure sensor, a vibration sensor, a microphone, etc.) that can measure information inside the water pipe P1.

[0020] The valve box 100 serves to form a space above the valve 10. The valve box 100 is buried in the ground and disposed above the valve 10. The upper part of the valve 10 (such as the upper part of the valve stem 11 for operating the valve body) is disposed so as to be exposed within the valve box 100.

[0021] The communication unit 20 is a device for exchanging information between the valve 10 and another device (a server 50 in this embodiment). The communication unit 20 is configured to be capable of wireless communication. The communication unit 20 can exchange information with the server 50 via a mobile phone line, for example, by transmitting and receiving radio waves to and from a nearby wireless base station. The communication unit 20 is connected to a battery 30 that serves as a power source. Power from the battery 30 can be supplied to the sensor S via the communication unit 20. The communication unit 20 and the sensor S can be operated using power from the battery 30. The communication unit 20 and the battery 30 are arranged in the valve box 100.

[0022] The portable terminal 40 is a terminal carried by a worker A1 who performs work (e.g., maintenance work) on the water pipe P1. The portable terminal 40 is configured as a device (e.g., a smartphone, a tablet terminal, etc.) that can be carried by the worker A1. The portable terminal 40 can obtain information about the inside of the water pipe P1 acquired by the valve 10 by viewing information processed by the server 50 (information about the valve 10 received via the communication unit 20).

[0023] The server 50 performs appropriate processing in response to requests from other devices. The server 50 is, for example, a cloud server (strictly speaking, a server virtually constructed in a cloud server). The server 50 can obtain information about the inside of the water pipe P1 acquired by the valve 10 by receiving a signal from the valve 10 via the communication unit 20. The server 50 can also process the information about the inside of the water pipe P1.

[0024] The administrator terminal 60 is a terminal used by an administrator A2 who manages the water pipe P1. The administrator terminal 60 includes a computing device (e.g., a CPU, etc.), a storage device (e.g., a HDD, etc.), and an input / output device (e.g., a mouse, a keyboard, a display, etc.). The administrator terminal 60 is connected to the server 50 via a network line. The administrator terminal 60 can obtain predetermined information (e.g., information inside the water pipe P1 and the results of processing the information by the server 50) from the server 50 by transmitting a signal to the server 50.

[0025] Next, the processing of the server 50 will be described with reference to FIG. 1 and FIG.

[0026] As described above, the measurement results of the sensor S are transmitted to the server 50 via the communication unit 20. At this time, information that uniquely identifies the valve 10 (e.g., a specific ID, etc.) and the measurement date and time are transmitted to the server 50 in association with the measurement results. The server 50 appropriately stores the information thus transmitted. Specifically, for example, the server 50 registers the measurement results of the sensor S in a specific database constructed in advance.

[0027] The server 50 performs appropriate processing on the thus stored measurement results of the sensor S. Specifically, for example, in response to a request from the administrator terminal 60 or the like, the server 50 extracts data from the database, generates a screen (for example, a screen created in an html (HyperText Markup Language) document or the like), and makes the generated screen viewable from the administrator terminal 60 or the like.

[0028] More specifically, the server 50 generates a screen displaying the results of measurements (hereinafter, as an example, the "pressure" is measured) by the sensors S of the valves 10 connected to the water pipe P1 in response to a request from the manager terminal 60. By displaying the screen on the manager terminal 60, the manager A2 can check the pressures at multiple locations. Based on the check results, the manager A2 can optimize the pump operation of the water transmission and distribution facility P. The manager A2 can also determine whether or not a large-scale leak is occurring in the water pipe P1 based on the presence or absence of an abnormality in the pressure.

[0029] Furthermore, in response to a request from the manager terminal 60, the server 50 creates a screen in which the position information (e.g., latitude and longitude) of the valve 10 and the pressure measurement results are superimposed on the map information. By displaying this screen on the manager terminal 60, the manager A2 can confirm the relationship between the pressure and the position information. This allows the manager A2 to quickly determine the location of the water leak and measures to take against the leak (e.g., which valve 10 should have its flow path closed, etc.).

[0030] Furthermore, the server 50 generates a screen displaying the pressure measured at a specific valve 10 in response to a request from the portable terminal 40. By displaying the screen on the portable terminal 40, the worker A1 can determine whether or not to open or close the valve 10 based on the pressure measurement result.

[0031] Next, the configuration of the valve box 100 will be described.

[0032] 2 and 3 is a box-shaped member that forms a space above the valve 10. The valve box 100 mainly comprises a valve box body 110, a bottom plate 120, a cover member 130, a position adjustment jig 140, and a housing member 150.

[0033] The valve box body 110 is a member that mainly forms the side surface of the valve box 100. The valve box body 110 is formed to be hollow. The valve box body 110 of this embodiment is formed to be cylindrical with its axial direction oriented in the vertical direction. As shown in Figures 4(a) and 5, the valve box body 110 has a female thread portion 111.

[0034] The female thread portion 111 is formed so as to be able to screw into a first bolt 142, which will be described later. The female thread portion 111 is formed in the middle of the top and bottom of the valve box body 110. A plurality of female thread portions 111 (two in this embodiment) are formed along the circumferential direction CD of the valve box body 110.

[0035] 2 and 3 is a member that mainly forms the bottom surface of the valve box 100. The bottom plate 120 is formed of a plate-like member. In the illustrated example, the bottom plate 120 is formed in a circular shape in a plan view that is slightly larger than the valve box body 110. An opening that passes through the bottom plate 120 from top to bottom is formed in the center of the bottom plate 120. The bottom plate 120 is disposed so that an upper portion of the valve stem 11 of the valve 10 is exposed inside the valve box 100 through the opening. The bottom plate 120 is provided at the lower portion of the valve box body 110.

[0036] The lid member 130 is a member that mainly forms the upper surface of the valve box 100. The lid member 130 is formed of a plate-like member. In the illustrated example, the lid member 130 is formed in a circular shape in a plan view with a diameter sufficient to cover the opening at the top of the valve box body 110. The lid member 130 is provided on the top of the valve box body 110. The lid member 130 is provided so as to be able to be opened and closed relative to the valve box body 110. By opening the lid member 130, various tasks (operation of the valve 10, maintenance, etc.) inside the valve box 100 can be performed from the ground.

[0037] The cover member 130 has a hole 131. The hole 131 is formed so as to penetrate the cover member 130 in the up-down direction. By forming the hole 131 in this manner, air can pass in and out between the valve box body 110 and the ground. As a result, for example, when the water level (groundwater level) of groundwater seeping into the valve box body 110 changes, air can pass in and out between the valve box body 110 and the ground, and pressure fluctuations within the valve box body 110 can be suppressed.

[0038] 3, a plurality of holes 131 are formed in the cover member 130. The plurality of holes 131 are formed at equal intervals in the circumferential direction CD of the valve box body 110. The worker A1 can open the cover member 130 by hooking a tool on the hole 131.

[0039] 4 and 5 is for adjusting the position of a target device. The position adjustment jig 140 is provided on the inner surface of the valve box 100 (valve box body 110). Note that the target device in this embodiment is assumed to be the communication unit 20 and battery 30 arranged in the valve box 100. The position adjustment jig 140 includes a plate 141, a first bolt 142, a bracket 143, and a second bolt 144.

[0040] The plate 141 is a longitudinal member extending along the up-down direction. The plate 141 is disposed with its plate surface facing the radial direction RD of the valve box body 110. The plate 141 is also disposed adjacent to the inner surface of the valve box body 110 on the inside in the radial direction RD. Two plates 141 are disposed along the circumferential direction CD. As shown in Fig. 6, the plate 141 has an elongated hole 141a and a female screw portion 141b.

[0041] The long hole 141a is formed to extend in the up-down direction. The long hole 141a is also formed to penetrate the plate 141 in the thickness direction (radial direction RD). The long hole 141a overlaps with the female screw portion 111 when viewed in the radial direction RD.

[0042] The female screw portion 141b is formed so as to be able to screw into a second bolt 144, which will be described later. The female screw portion 141b is formed above the elongated hole 141a.

[0043] The first bolt 142 shown in Figures 4(b) and 5 is for fixing the plate 141 to the valve box body 110. The width of the head of the first bolt 142 is larger than the width of the long hole 141a. On the other hand, the outer diameter of the shaft of the first bolt 142 is smaller than the width of the long hole 141a. The shaft of the first bolt 142 is inserted into the long hole 141a and is screwed into each of the two female thread portions 111 of the valve box body 110 via the long hole 141a. Note that for the sake of convenience, the first bolt 142 and the second bolt 144 are omitted from Figure 4(a).

[0044] 4 and 5 is for supporting a target device. The bracket 143 is disposed adjacent to the inside of the two plates 141 in the radial direction RD. The bracket 143 includes a connecting portion 143a, a long hole 143b, and an attachment portion 143c.

[0045] The connecting portion 143a is a plate-like portion extending in the circumferential direction CD. The connecting portion 143a is formed to be longer than the distance between the two plates 141 in the circumferential direction CD.

[0046] The long hole 143b is formed to extend along the circumferential direction CD. The long hole 143b is also formed to penetrate the connecting portion 143a in the thickness direction (radial direction RD). Two long holes 143b are formed along the circumferential direction CD. The two long holes 143b overlap with the two female screw portions 141b (see FIG. 6) when viewed in the radial direction RD.

[0047] The mounting portion 143c is a portion to which the accommodating member 150, which will be described later, is attached. As shown in Fig. 5, the mounting portion 143c is formed so that the accommodating member 150 can be placed thereon. The accommodating member 150 can be attached to the mounting portion 143c by an appropriate fixing member such as a bolt.

[0048] 4(b) and 5 is for fixing the bracket 143 to the two plates 141. The width of the head of the second bolt 144 is larger than the width of the long hole 143b. On the other hand, the outer diameter of the shaft of the second bolt 144 is smaller than the width of the long hole 143b. The shaft of the second bolt 144 is inserted into the long hole 143b and is screwed into the female thread portions 141b of the two plates 141 via the long holes 143b.

[0049] 2 and 5 is for housing the target device (the communication unit 20 and the battery 30). The housing member 150 is formed in a hollow box shape. With the target device housed in the housing member 150, the housing member 150 is fixed to the attachment portion 143c by an appropriate fixing member such as a bolt. The housing member 150 can protect the target device from dust and water.

[0050] The following describes a procedure for adjusting the position of a target device using the position adjustment jig 140 configured as described above. The position adjustment jig 140 can adjust the position of the target device in the circumferential direction CD and in the up-down direction.

[0051] First, an example of a procedure for adjusting the position in the circumferential direction CD will be described below. In this embodiment, the position of the target device in the circumferential direction CD can be adjusted by adjusting the mounting position of the bracket 143 of the position adjustment jig 140.

[0052] Specifically, the second bolt 144 shown in Fig. 4(b) is loosened. This releases the bracket 143 from being fixed to the plate 141. In this state, the bracket 143 can be moved in the circumferential direction CD relative to the plate 141 and the second bolt 144 within the range of the long hole 143b of the bracket 143. Furthermore, by fastening the second bolt 144 at a predetermined circumferential position, the bracket 143 can be fixed at that circumferential position.

[0053] In this manner, the mounting position of bracket 143 is adjusted. Since the target device is mounted to bracket 143, the position of the target device in the circumferential direction CD is adjusted by adjusting the mounting position of bracket 143. In this manner, in this embodiment, the position of the target device in the circumferential direction CD can be adjusted by long hole 143b and second bolt 144. Note that in this embodiment, the length of long hole 143b and the circumferential position of plate 141 are appropriately set so that communication unit 20 can be disposed directly below hole 131 (see FIG. 2) of cover member 130.

[0054] Next, a procedure for adjusting the position of the target device in the vertical direction (height direction) will be described. In this embodiment, the height position of the target device can be adjusted by adjusting the mounting position of the plate 141 of the position adjustment jig 140.

[0055] Specifically, the first bolt 142 shown in Fig. 4(b) is loosened. This releases the fixation of the plate 141. In this state, the plate 141 can be moved vertically relative to the valve box body 110 and the first bolt 142 within the range of the elongated hole 141a of the plate 141. Furthermore, by fastening the first bolt 142 at a predetermined height position, the plate 141 can be fixed at that height position.

[0056] In this manner, the mounting position of plate 141 is adjusted. Since bracket 143 is attached to plate 141, the height position of the target device is adjusted by adjusting the mounting position of plate 141. In this manner, in this embodiment, the height position of the target device can be adjusted by long hole 141a and first bolt 142.

[0057] By adjusting the circumferential position and the height position of the target device according to the above-mentioned procedure, the position adjustment of the target device can be suitably performed.

[0058] For example, by adjusting the height position of the target device, the target device can be located farther away from the valve stem 11 shown in Fig. 2. This makes it easier to ensure space for operation and maintenance of the valve 10, improving workability. Even if the relative position between the valve 10 and the valve box body 110 changes due to a design change, the change in the relative position can be accommodated by adjusting the height position and circumferential position of the target device.

[0059] Furthermore, the state of the groundwater seeping into the valve box body 110 may change due to changes in the surrounding environment, etc. For example, due to changes in the surrounding environment, the maximum water level of the groundwater may rise from the initial state (when the valve box 100 was installed). By raising the height position of the target equipment in response to such an increase in the maximum water level, it is possible to prevent the target equipment from being submerged.

[0060] 2 (hole 131) as a reference, the radio wave strength (communication performance) of communication unit 20 can be improved. More specifically, the radio wave strength of communication unit 20 can be improved by adjusting the position of the target device so that radio waves transmitted and received between communication unit 20 and a wireless base station are less likely to be blocked by cover member 130. For example, the radio wave strength of communication unit 20 can be improved by adjusting the position of the target device in the circumferential direction CD so that communication unit 20 is located directly below hole 131 of cover member 130.

[0061] Further, the radio wave intensity of the communication unit 20 may change depending on the depth from the hole 131 (installation depth). In this embodiment, by adjusting the height position of the target device, the communication unit 20 can be moved closer to or further away from the hole 131 to change the depth from the hole 131. For example, the worker A1 can place the communication unit 20 at an appropriate height position where the radio wave intensity is good by adjusting the height position of the target device while measuring the radio wave intensity of the communication unit 20. Similarly to the height position, the worker A1 can also place the communication unit 20 at an appropriate circumferential position by adjusting the position while measuring the radio wave intensity of the communication unit 20.

[0062] Furthermore, the depth from the hole 131 may change after the valve box 100 is installed. For example, the depth from the hole 131 may change due to a change in the condition of the pavement around the valve box 100. By adjusting the height position of the target device in response to such a change in depth, the depth from the hole 131 can be made appropriate, and deterioration of radio wave intensity can be suppressed.

[0063] Furthermore, the radio wave strength of the communication unit 20 may change depending on changes in the surrounding environment (such as the state of the groundwater level and the presence or absence of buildings). For example, the radio wave strength of the communication unit 20 may deteriorate due to the above-mentioned changes in the maximum water level, etc. Furthermore, for example, the radio wave strength of the communication unit 20 may deteriorate when a structure such as a building is present (when one is erected) around the valve box 100.

[0064] Therefore, the worker A1 can place the target device at an appropriate height according to the change in the surrounding environment by adjusting the height of the target device while measuring the radio wave intensity of the communication unit 20. This makes it possible to prevent the deterioration of the radio wave intensity.

[0065] As described above, the position adjustment jig 140 of this embodiment is provided on the inner surface of the valve box 100 located above the valve 10 buried in the ground, and is capable of adjusting the position of the target equipment (the communication unit 20 and the battery 30), and is equipped with a horizontal adjustment section (long hole 143b and second bolt 144) that can adjust the position of the target equipment in the horizontal direction (circumferential direction CD in this embodiment), and a height adjustment section (long hole 141a and first bolt 142) that can adjust the position of the target equipment in the height direction.

[0066] By configuring in this way, the position of the target device can be adjusted appropriately. For example, when the communication unit 20 capable of communication is used as the target device, the position of the target device can be adjusted so that the radio wave intensity (communication performance) of the target device can be secured. Also, the height position of the target device can be adjusted according to the groundwater level.

[0067] In addition, at least one of the horizontal adjustment portion and the height adjustment portion has an adjustment hole (long holes 141a-143b) formed in a longitudinal shape, and a movable member (first bolt 142 and second bolt 144) arranged so as to be relatively movable within the adjustment hole.

[0068] By configuring it in this way, the position adjustment jig 140 can be made to have a simple configuration.

[0069] As described above, the position adjustment method for the target equipment according to this embodiment is a position adjustment method for the target equipment using the position adjustment jig 140, and adjusts the position of the target equipment so as to move the target equipment closer to or farther away from the hole 131 formed in the cover member 130 (cover) attached to the upper part of the valve box 100.

[0070] With this configuration, the position of the target device can be adjusted using hole 131 as a reference, thereby improving the communication performance of the target device via hole 131.

[0071] The communication unit 20 and the battery 30 according to the present embodiment are an embodiment of a target device according to the present invention. Moreover, the elongated hole 143b and the second bolt 144 according to this embodiment are one embodiment of a horizontal adjustment portion according to the present invention. Moreover, the elongated hole 141a and the first bolt 142 according to this embodiment are one embodiment of a height direction adjustment portion according to the present invention. Moreover, the elongated holes 141a and 143b according to this embodiment are one embodiment of the adjustment hole according to the present invention. Moreover, the first bolt 142 and the second bolt 144 according to this embodiment are one embodiment of the moving member according to the present invention. Moreover, the lid member 130 according to this embodiment is one embodiment of the lid according to the present invention.

[0072] Another embodiment of the present invention will be described below. In the description of the another embodiment, the same reference numerals as those in the first embodiment are used for the members configured similarly to those in the first embodiment, and the description thereof will be omitted.

[0073] In the above-described first embodiment, as shown in Fig. 5, the second bolt 144 is screwed into the female thread portion 141b of the plate 141. However, as in the second embodiment shown in Fig. 7, it is also possible to configure the second bolt 144 to be screwed into the nut 246. The position adjustment jig 240 of the second embodiment includes a plate 241, a first bolt 142, a bracket 143, a second bolt 144, a spacer 245, and a nut 246.

[0074] The plate 241 of the second embodiment is formed to be thinner than the plate 141 of the first embodiment. The plate 241 does not have the female screw portion 141b as in the first embodiment.

[0075] The spacer 245 is disposed between the plate 241 and the valve box body 110. The spacer 245 has a through hole 245a. The through hole 245a is formed to penetrate the spacer 245 in the radial direction RD. The through hole 245a is also formed to allow the shaft portion of the first bolt 142 to be inserted therethrough. The first bolt 142 is screwed into the female thread portion 111, whereby the spacer 245 is sandwiched and fixed between the plate 141 and the valve box body 110.

[0076] With the spacer 245 thus interposed between the plate 141 and the valve box body 110, the plate 241 is disposed at a position spaced apart from the surface (inner surface) of the valve box body 110 in the radial direction RD.

[0077] The nut 246 is disposed between the plate 241 and the valve box body 110. The bracket 143 can be fixed to the plate 241 by screwing the second bolt 144 into the nut 246.

[0078] According to the position adjustment jig 240 of the second embodiment, the bracket 143 can be fixed to the plate 241 without forming the female screw portion 141b. This allows the plate 141 to have a simple shape.

[0079] In the above-described first embodiment, the position (height position) of the plate 141 in the up-down direction is adjustable with respect to the valve box body 110, as shown in Figures 5 and 6. In the first embodiment, the position of the bracket 143 in the circumferential direction CD is adjustable with respect to the plate 141, as shown in Figure 4. This is just one example, and the direction in which the position of the plate 141 attached to the valve box body 110 is adjusted and the direction in which the position of the bracket 143 attached to the plate 141 is adjusted can be changed as appropriate. Figure 8 shows a position adjustment jig 340 according to a third embodiment, in which the direction in which the position of the plate 141 etc. is adjusted is different from that of the first embodiment.

[0080] A position adjustment jig 340 according to the third embodiment is configured to be able to adjust the circumferential position of a plate 341 attached to the valve box body 110 and the vertical position of a bracket 343 attached to the plate 341. The position adjustment jig 340 includes the plate 341, a first bolt 142, a bracket 343, and a second bolt 144.

[0081] 8(a) and 9 is formed in a plate shape extending along the circumferential direction CD. As shown in Fig. 9, the plate 341 has an elongated hole 341a and a female screw portion 341b.

[0082] The long hole 341a is formed to extend along the circumferential direction CD. The long hole 341a is also formed to penetrate the plate 341 in the thickness direction (radial direction RD). The long hole 341a is formed so that the shaft portion of the first bolt 142 can be inserted therethrough. Two long holes 341a are formed along the circumferential direction CD. The two long holes 341a overlap with the two female screw portions 111 (see FIG. 8(a)) when viewed in the radial direction RD.

[0083] The female screw portion 341b is formed so as to be able to screw into the second bolt 144. Two female screw portions 141b are formed along the circumferential direction CD. Note that, for convenience of explanation, the plate 341 is depicted as a thin plate in Fig. 8(a) , but the plate 341 can be formed so as to have a thickness sufficient to fasten the second bolt 144 to the female screw portion 141b.

[0084] The plate 341 is fixed to the valve box body 110 by screwing the first bolt 142 into the female thread portion 111 through the long hole 341a. Furthermore, by loosening the first bolt 142, the plate 341 can move relative to the valve box body 110 in the circumferential direction CD within the range of the long hole 341a.

[0085] A bracket 343 shown in FIG. 8 includes a coupling portion 343a, a long hole 343b, a connection portion 343c, and an attachment portion 343d.

[0086] The connecting portion 343a is formed in a plate shape extending in the up-down direction. The connecting portion 343a is disposed adjacent to the plate 341 on the inner side in the radial direction RD. Two connecting portions 343a are disposed along the circumferential direction CD.

[0087] The long hole 343b is formed to extend in the up-down direction. The long hole 343b is also formed to penetrate the connecting portion 343a in the thickness direction (radial direction RD). The long hole 343b is formed so that the shaft portion of the second bolt 144 can be inserted therethrough. The long hole 343b overlaps with the female screw portion 341b (see FIG. 9) when viewed in the radial direction RD.

[0088] The connecting portion 343c is formed to connect the two coupling portions 343a. The connecting portion 343c is disposed at an appropriate interval from the plate 341 so as not to interfere with the first bolt 142.

[0089] The mounting portion 343d is formed so that the accommodating member 150 can be placed thereon. For example, as shown in Fig. 8(b), the mounting portion 343d is formed in a substantially U-shape with an open upper portion when viewed in the radial direction RD of the valve box body 110. The mounting portion 343d is appropriately fixed to the connection portion 343c. The accommodating member 150 is fixed to the mounting portion 343d by wrapping a band 343e around the accommodating member 150 while it is placed on the mounting portion 343d.

[0090] The bracket 343 is fixed to the plate 341 by screwing the second bolt 144 into the female thread portion 341b through the long hole 343b. Furthermore, by loosening the second bolt 144, the bracket 343 can move vertically relative to the plate 341 within the range of the long hole 343b.

[0091] In this embodiment, since the two linking parts 343a are connected to each other by the connecting part 343c, the two linking parts 343a can be moved together by the vertical movement of the connecting part 343c. This allows the adjustment of the height position of the bracket 343 (target device) to be performed efficiently.

[0092] Although the first embodiment of the present invention has been described above, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention described in the claims.

[0093] For example, the management system 1 (valve 10) is described as being installed in a water supply and sewerage facility, but the application of the valve 10 is not limited to water supply and sewerage facilities, and the valve 10 can be applied to various facilities.

[0094] In the above embodiment, the communication unit 20 exchanges information with the server 50 via a mobile phone line, but the communication path of the communication unit 20 is not limited to this. For example, in preparation for a case where a mobile phone line becomes unavailable due to a disaster or the like, the communication unit 20 may be able to communicate with the outside via a separate communication means (Wi-Fi, etc.). This makes it possible to directly acquire information about the inside of the flow path without going through the server 50 or the like by directly communicating between the data logger and the communication unit 20.

[0095] In addition, in the above embodiment, the positions of the communication unit 20 and the battery 30 are adjusted as an example, but the target devices of the present invention are not limited to the communication unit 20 and the battery 30, and the position of any device can be adjusted.

[0096] In the above embodiment, the valve box 100 is formed to have a circular shape when viewed from above, but there are no particular limitations on the shape of the valve box 100. For example, the valve box 100 may be formed to have a rectangular shape when viewed from above.

[0097] In the above embodiment, the position of the target device in the circumferential direction CD can be adjusted, but the horizontal adjustment unit according to the present invention only needs to be able to adjust the position of the target device in the horizontal direction, and can also adjust the position of the target device in a direction different from the circumferential direction CD. For example, the horizontal adjustment unit may be able to adjust the position of the target device in the radial direction RD. In this way, the direction in which the horizontal adjustment unit adjusts the position of the target device can be changed as appropriate.

[0098] In the above embodiment, the position of the target device is adjusted by the long hole 141a, the first bolt 142, etc., but the present invention is not limited to this, and the specific structure of the position adjustment jig is not limited as long as the position of the target device can be adjusted. For example, it is possible to adjust the position of the target device by attaching a rail member to the inner surface of the valve box body 110 and moving the target device along the rail member. In addition, it is possible to adjust the position of the target device by using holes having a shape different from the long holes 141a and 143b. For example, instead of the long hole 141a shown in FIG. 4(b), it is possible to form a plurality of circular holes in the plate 141 through which the shaft of the first bolt 142 can be inserted, and to screw the first bolt 142 into the female screw portion 111 through one of the plurality of holes, thereby gradually adjusting the position of the target device.

[0099] In addition, in the above embodiment, an example is shown in which the communication unit 20 is positioned directly below the hole portion 131 by adjusting the position of the target device in the circumferential direction CD, but this is just one example, and it is not necessarily required that the communication unit 20 is positioned directly below the hole portion 131.
