Description

Technical Field

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

Background Art

[0002] Conventionally, a technique of a valve provided in a pipeline such as a water pipe and opening and closing a fluid flow path is known (for example, Patent Document 1).

[0003] Since a large number of such valves are installed in a pipeline network, by providing various sensors (for example, a water quality monitoring device, a flow meter, etc.) for acquiring information in the pipeline (flow path) in this valve, it is considered that information on the pipeline network can be acquired widely and permanently.

[0004] Here, when providing various sensors as described above in the valve, not only the sensor but also various devices associated with the sensor (for example, a battery, a communication terminal device for transmitting a detection result, etc.) need to be provided in a valve box disposed above the valve.

[0005] However, since the space in the valve box is limited, there is a concern that it may be difficult to secure a space for operating and maintaining the valve when arranging a device such as a battery in the valve box.

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

[0007] Therefore, a technique that can preferably perform position adjustment of target devices such as a battery and a communication terminal device is required.

Mode for Carrying Out the Invention

[0016] Hereinafter, the directions indicated by arrow U and arrow D in the figure will be defined as the upward direction and the downward direction, respectively, for explanation. For convenience of explanation, the members are schematically shown in the figure, and the specific shapes, dimensions, etc. are not limited to those shown in the figure.

[0017] Hereinafter, the position adjusting tool 140 according to an embodiment of the present invention will be described. First, referring to FIGS. 1 and 2, the management system 1 using the valve box 100 in which the position adjusting tool 140 is provided will be described.

[0018] Management system 1 manages the fluid in the flow path using a valve 10, which will be described later. More specifically, management system 1 is installed in a water and sewage facility and manages the water supplied from the water transmission and distribution facility P and circulating in the water pipe P1 (flow path). For example, management system 1 can acquire and verify information (e.g., water pressure) from within the water pipe P1. Management system 1 comprises a 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] Valve 10 is for controlling the flow of water within the water pipe P1. Valve 10 consists of a valve (e.g., a gate valve, a butterfly valve, etc.) that opens and closes the flow path within the water pipe P1 using a valve body. Valve 10 is buried underground and installed in the middle of the water pipe P1. Valve 10 is equipped with various sensors S (e.g., a pressure sensor, a vibration sensor, a microphone, etc.) capable of measuring information within the water pipe P1.

[0020] The valve box 100 is intended to create space above the valve 10. The valve box 100 is buried underground and positioned 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 positioned to be exposed inside the valve box 100.

[0021] The communication unit 20 is a device for exchanging information between the valve 10 and other devices (in this embodiment, the server 50). The communication unit 20 is configured to be wirelessly wireless. The communication unit 20 can exchange information with the server 50 via a mobile phone line by, for example, sending and receiving radio waves to and from a nearby wireless base station. The communication unit 20 is connected to a battery 30, which is 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 operate using power from the battery 30. The communication unit 20 and the battery 30 are located inside the valve box 100.

[0022] The portable terminal 40 is a terminal carried by worker A1 who performs work related to the water pipe P1 (for example, maintenance work). The portable terminal 40 consists of a device that worker A1 can carry (for example, a smartphone or tablet). The portable terminal 40 can obtain information about the water pipe P1 acquired by the valve 10 by viewing the information processed by the server 50 (information from the valve 10 received via the communication unit 20).

[0023] Server 50 processes data as needed in response to requests from other devices. Server 50 is configured, for example, as a cloud server (more precisely, a server virtually built within a cloud server). By receiving signals from valve 10 via communication unit 20, server 50 can obtain information about the water pipe P1 acquired by valve 10. Server 50 can also process the information about the water pipe P1.

[0024] The administrator terminal 60 is a terminal used by administrator A2, who manages the water pipe P1. The administrator terminal 60 is equipped with a computing device (e.g., CPU), a storage device (e.g., HDD), and input / output devices (e.g., mouse, keyboard, and display). The administrator terminal 60 is connected to the server 50 via a network line. By sending signals to the server 50, the administrator terminal 60 can obtain predetermined information from the server 50 (e.g., information within the water pipe P1 and the results of processing that information by the server 50).

[0025] Next, the processing of server 50 will be explained with reference to Figures 1 and 2.

[0026] As described above, the measurement results from the sensor S are transmitted to the server 50 via the communication unit 20. At this time, the server 50 receives information that uniquely identifies the valve 10 (for example, a predetermined ID, etc.) and the measurement date and time, associated with the measurement results. The server 50 stores the transmitted information as appropriate. Specifically, for example, the server 50 registers the measurement results from the sensor S in a predetermined database that has been built in advance.

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

[0028] More specifically, in response to a request from the administrator terminal 60, the server 50 generates a screen that displays the results measured by the sensors S of each valve 10 connected to the water pipe P1 (in this example, "pressure" is assumed to have been measured). By displaying this screen on the administrator terminal 60, administrator A2 can check the pressure at multiple locations. Based on these checks, administrator A2 can optimize the operation of the pumps in the water supply and distribution facility P. Administrator A2 can also determine whether or not a large-scale water leak has occurred in the water pipe P1 based on the presence or absence of pressure abnormalities.

[0029] Furthermore, in response to a request from the administrator terminal 60, the server 50 creates a screen that overlays the location information (e.g., latitude and longitude) and pressure measurement results of the valves 10 onto the map information. By displaying this screen on the administrator terminal 60, administrator A2 can confirm the relationship between pressure and location information. This allows administrator A2 to quickly determine the location of the water leak and the countermeasures to be taken against the leak (e.g., which valve 10 to close the flow path).

[0030] Furthermore, the server 50 generates a screen displaying the pressure measured by a predetermined valve 10 in response to a request from the portable terminal 40. By displaying this screen on the portable terminal 40, worker A1 can decide 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] The valve box 100 shown in Figures 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 lid member 130, a position adjustment jig 140, and a housing member 150.

[0033] The valve box body 110 is a component that mainly forms the side surface of the valve box 100. The valve box body 110 is formed in a hollow shape. In this embodiment, the valve box body 110 is formed in a cylindrical shape with its axial direction oriented vertically. As shown in Figures 4(a) and 5, the valve box body 110 is equipped with a female threaded portion 111.

[0034] The female threaded portion 111 is formed to be screwable with the first bolt 142, which will be described later. The female threaded portion 111 is formed in the upper and lower middle parts of the valve box body 110. Multiple female threaded portions 111 are formed along the circumferential direction CD of the valve box body 110 (two in this embodiment).

[0035] The bottom plate 120 shown in Figures 2 and 3 is a component that mainly forms the bottom surface of the valve box 100. The bottom plate 120 is made of a plate-shaped material. In the illustrated example, the bottom plate 120 is formed in a circular shape in plan view, slightly larger than the valve box body 110. An opening is formed in the center of the bottom plate 120, penetrating it vertically. The upper part of the valve stem 11 of the valve 10 is exposed inside the valve box 100 through this opening in the bottom plate 120. The bottom plate 120 is provided at the bottom 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 made of a plate-shaped member. In the illustrated example, the lid member 130 is formed in a circular shape in plan view, having a diameter large enough to cover the opening at the top of the valve box body 110. The lid member 130 is installed on the top of the valve box body 110. The lid member 130 is installed so that it can be opened and closed relative to the valve box body 110. By opening the lid member 130, various operations inside the valve box 100 (operation of the valve 10, maintenance, etc.) can be performed from the ground.

[0037] The lid member 130 is provided with a hole 131. The hole 131 is formed to penetrate the lid member 130 in the vertical direction. The formation of the hole 131 allows air to enter and exit between the valve box body 110 and the ground. This allows air to enter and exit between the valve box body 110 and the ground, suppressing pressure fluctuations inside the valve box body 110, for example, when the water level of groundwater entering the valve box body 110 changes.

[0038] As shown in Figure 3, multiple holes 131 are formed in the lid member 130. The multiple holes 131 are formed at equal intervals in the circumferential direction CD of the valve box body 110. Worker A1 can open the lid member 130 by hooking a tool into the holes 131.

[0039] The position adjustment jig 140 shown in Figures 4 and 5 is used to adjust the position of the target equipment. The position adjustment jig 140 is provided on the inner surface of the valve box 100 (valve box body 110). In this embodiment, the target equipment is assumed to be the communication unit 20 and the battery 30 located inside the valve box 100. The position adjustment jig 140 comprises a plate 141, a first bolt 142, a bracket 143, and a second bolt 144.

[0040] Plate 141 is a longitudinal member oriented vertically. Plate 141 is positioned with its plate surface facing the radial direction RD of the valve box body 110. Plate 141 is also positioned adjacent to the inner surface of the valve box body 110 in the radial direction RD. Two plates 141 are arranged along the circumferential direction CD. As shown in Figure 6, plate 141 is equipped with an elongated hole 141a and a female threaded portion 141b.

[0041] The elongated hole 141a is formed to extend along the vertical direction. Furthermore, the elongated hole 141a is formed to penetrate the plate 141 in the thickness direction (radial direction RD). In the radial direction RD view, the elongated hole 141a overlaps with the female screw portion 111.

[0042] The female threaded portion 141b is formed to be screwable with the second bolt 144, which will be described later. The female threaded portion 141b is formed above the elongated hole 141a.

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

[0044] The bracket 143 shown in Figures 4 and 5 is for supporting the target equipment. The bracket 143 is positioned adjacent to the two plates 141 on the inside in the radial direction RD. The bracket 143 comprises a connecting portion 143a, an elongated hole 143b, and a mounting portion 143c.

[0045] The connecting portion 143a is a plate-shaped portion that extends along the circumferential direction CD. The connecting portion 143a is formed to be longer than the distance between the two plates 141 along the circumferential direction CD.

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

[0047] The mounting portion 143c is the part to which the housing member 150, described later, is attached. As schematically shown in Figure 5, the mounting portion 143c is formed so that the housing member 150 can be placed on it. The housing member 150 can be attached to the mounting portion 143c by appropriate fixing members such as bolts.

[0048] The second bolt 144 shown in Figures 4(b) and 5 is used to fix the bracket 143 to the two plates 141. The width of the head of the second bolt 144 is greater than the width of the elongated hole 143b. On the other hand, the outer diameter of the shaft of the second bolt 144 is smaller than the width of the elongated hole 143b. The shaft of the second bolt 144 is inserted through the elongated hole 143b and screwed into the female threaded portions 141b of the two plates 141 via the elongated hole 143b.

[0049] The housing member 150 shown in Figures 2 and 5 houses the target equipment (communication unit 20 and battery 30). The housing member 150 is formed in the shape of a hollow box. With the target equipment housed inside, the housing member 150 is fixed to the mounting portion 143c by appropriate fixing members such as bolts. The housing member 150 can protect the target equipment from dust and water.

[0050] The following describes the procedure for adjusting the position of the 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 vertical direction, respectively.

[0051] The following describes an example of a procedure for adjusting the position in the circumferential CD direction. In this embodiment, the position of the target device in the circumferential CD direction 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 Figure 4(b) is loosened. This releases the bracket 143 from its fixation to the plate 141. In this state, the bracket 143 can be moved relative to the plate 141 and the second bolt 144 in the circumferential direction CD within the range of the elongated hole 143b of the bracket 143. Furthermore, by fastening with the second bolt 144 at a predetermined circumferential position, the bracket 143 can be fixed in that circumferential position.

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

[0054] Next, the 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 Figure 4(b) is loosened. This releases the plate 141 from its fixed position. 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 with the first bolt 142 at a predetermined height position, the plate 141 can be fixed at that height position.

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

[0057] By adjusting the circumferential position and height position of the target device according to the procedure described above, the position of the target device can be adjusted appropriately.

[0058] For example, by adjusting the height of the target equipment, it is possible to position the equipment farther away from the valve stem 11 shown in Figure 2. This makes it easier to secure space for operating and maintaining the valve 10, thereby improving work efficiency. Furthermore, even if the relative position between the valve 10 and the valve box body 110 changes due to a design change, this change in relative position can be accommodated by adjusting the height and circumferential position of the target equipment.

[0059] Furthermore, the state of groundwater entering the valve box body 110 may change due to changes in the surrounding environment. For example, changes in the surrounding environment may cause the maximum groundwater level to rise compared to the initial state (when the valve box 100 was installed). By raising the height of the equipment in response to this rise in the maximum groundwater level, it is possible to prevent the equipment from being submerged.

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

[0061] Furthermore, the radio wave intensity of the communication unit 20 may change depending on its depth (installation depth) from the hole 131. In this embodiment, the communication unit 20 can be moved closer to or further away from the hole 131 by adjusting the height position of the target equipment, thereby changing the depth from the hole 131. For example, worker A1 can adjust the height position of the target equipment while measuring the radio wave intensity of the communication unit 20 to position the communication unit 20 at an appropriate height that provides good radio wave intensity. Similarly, worker A1 can adjust the circumferential position of the communication unit 20 while measuring the radio wave intensity of the communication unit 20, thereby positioning the communication unit 20 at an appropriate circumferential position.

[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 changes in the condition of the pavement around the valve box 100. Therefore, by adjusting the height position of the target equipment in accordance with these changes in depth, the depth from the hole 131 can be made appropriate, thereby suppressing the deterioration of radio wave intensity.

[0063] Furthermore, the radio wave strength of the communication unit 20 may change depending on changes in the surrounding environment (groundwater level, presence or absence of buildings, etc.). For example, the radio wave strength of the communication unit 20 may deteriorate due to changes in the maximum water level as described above. Also, for example, the radio wave strength of the communication unit 20 may deteriorate if there are buildings such as skyscrapers around the valve box 100 (if they are constructed).

[0064] Therefore, worker A1 can adjust the height of the target device while measuring the radio wave strength of the communication unit 20, thereby positioning the target device at an appropriate height in response to these changes in the surrounding environment. This helps to suppress the deterioration of radio wave strength.

[0065] As described above, the position adjustment jig 140 according to this embodiment is provided on the inner surface of a valve box 100 positioned above a valve 10 buried in the ground, and is capable of adjusting the position of the target equipment (communication unit 20 and battery 30), and comprises a horizontal adjustment section (elongated 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 (elongated hole 141a and first bolt 142) that can adjust the position of the target equipment in the height direction.

[0066] This configuration allows for efficient positioning of the target device. For example, when a communication unit 20 capable of communication is used as the target device, the device's position can be adjusted to ensure sufficient radio wave intensity (communication performance). Furthermore, the height of the target device can be adjusted according to the groundwater level.

[0067] Furthermore, at least one of the horizontal adjustment section and the height adjustment section comprises an elongated adjustment hole (elongated hole 141a and 143b) and a movable member (first bolt 142 and second bolt 144) arranged to be relatively movable within the adjustment hole.

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

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

[0070] By configuring it in this way, the position of the target device can be adjusted using the hole 131 as a reference, thereby improving the communication performance of the target device via the hole 131.

[0071] Furthermore, the communication unit 20 and battery 30 in this embodiment are one form of the target device according to the present invention. Furthermore, the elongated hole 143b and the second bolt 144 according to this embodiment represent one form of the horizontal adjustment unit according to the present invention. Furthermore, the elongated hole 141a and the first bolt 142 according to this embodiment represent one form of the height adjustment unit according to the present invention. Furthermore, the elongated holes 141a and 143b according to this embodiment are one form of the adjustment holes according to the present invention. Furthermore, the first bolt 142 and the second bolt 144 according to this embodiment are one form of the movable member according to the present invention. Furthermore, the lid member 130 according to this embodiment is one embodiment of the lid according to the present invention.

[0072] The following describes another embodiment of the present invention. In the description of the other embodiment, components configured in the same way as in the first embodiment will be denoted by the same reference numerals as in the first embodiment, and their descriptions will be omitted.

[0073] In the first embodiment described above, as shown in Figure 5, the second bolt 144 is screwed into the female threaded portion 141b of the plate 141. However, as shown in the second embodiment in Figure 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 comprises 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 that is formed in the first embodiment.

[0075] The spacer 245 is positioned 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 radially RD. The through hole 245a is also formed to allow the shaft portion of the first bolt 142 to pass through. The spacer 245 is fixed by being sandwiched between the plate 141 and the valve box body 110 when the first bolt 142 is screwed into the female thread portion 111.

[0076] In this way, the spacer 245 is interposed between the plate 141 and the valve box body 110, so that the plate 241 is positioned radially away RD from the surface (inner surface) of the valve box body 110.

[0077] The nut 246 is positioned 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 a female screw portion 141b. This allows the plate 141 to have a simple shape.

[0079] Furthermore, in the first embodiment described above, as shown in Figures 5 and 6, the vertical position (height position) of the plate 141 relative to the valve box body 110 is adjustable. Also in the first embodiment, as shown in Figure 4, the circumferential position CD of the bracket 143 relative to the plate 141 is adjustable. 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 differs from that of the first embodiment.

[0080] The position adjustment jig 340 according to the third embodiment is configured to allow adjustment of 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 comprises a plate 341, a first bolt 142, a bracket 343, and a second bolt 144.

[0081] The plate 341 shown in Figures 8(a) and 9 is formed in a plate shape that extends along the circumferential direction CD. As shown in Figure 9, the plate 341 is provided with an elongated hole 341a and a female screw portion 341b.

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

[0083] The female threaded portion 341b is formed to be screwable with the second bolt 144. Two female threaded portions 141b are formed along the circumferential direction CD. In Figure 8(a), for the sake of explanation, the plate 341 is shown as a thin plate, but the plate 341 can be formed to have a thickness sufficient to fasten the second bolt 144 to the female threaded portion 141b.

[0084] The plate 341 is fixed to the valve box body 110 by screwing the first bolt 142 into the female threaded portion 111 via the elongated hole 341a. The plate 341 can also be moved relative to the valve box body 110 in the circumferential direction CD within the range of the elongated hole 341a by loosening the first bolt 142.

[0085] The bracket 343 shown in Figure 8 comprises a connecting portion 343a, an elongated hole 343b, a connecting portion 343c, and a mounting portion 343d.

[0086] The connecting portion 343a is formed in a plate shape that extends along the vertical direction. The connecting portion 343a is positioned adjacent to the plate 341 on the inside in the radial direction RD. Two connecting portions 343a are positioned along the circumferential direction CD.

[0087] The elongated hole 343b is formed to extend along the vertical direction. Furthermore, the elongated hole 343b is formed to penetrate the connecting portion 343a in the thickness direction (radial direction RD). The elongated hole 343b is formed so that the shaft portion of the second bolt 144 can be inserted through it. In a view along the radial direction RD, the elongated hole 343b overlaps with the female thread portion 341b (see Figure 9).

[0088] The connecting portion 343c is formed to connect the two connecting portions 343a. The connecting portion 343c is positioned with an appropriate gap between it and the plate 341 so as not to interfere with the first bolt 142.

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

[0090] Bracket 343 is fixed to plate 341 by screwing a second bolt 144 into the female threaded portion 341b via an elongated hole 343b. Bracket 343 can also be moved relative to plate 341 in the vertical direction within the range of the elongated hole 343b by loosening the second bolt 144.

[0091] In this embodiment, since the two connecting parts 343a are connected to each other by the connecting part 343c, the two connecting parts 343a can be moved together by the vertical movement of the connecting part 343c. This makes it possible to efficiently adjust the height position of the bracket 343 (target equipment).

[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 as described in the claims.

[0093] For example, although management system 1 (valve 10) is intended to be installed in water and sewage facilities, the application of valve 10 is not limited to water and sewage facilities, but can be applied to various types of equipment.

[0094] Furthermore, in the above embodiment, the communication unit 20 is shown as exchanging 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 case the mobile phone line becomes unusable due to a disaster or the like, the communication unit 20 may be made able to communicate with the outside world via a separate communication means (such as Wi-Fi). This makes it possible, for example, to have the data logger and the communication unit 20 communicate directly and to directly acquire information in the flow path without going through the server 50 or the like.

[0095] Furthermore, while the above embodiment shows the adjustment of the positions of the communication unit 20 and the battery 30 as an example, the devices to which the present invention applies are not limited to the communication unit 20 and the battery 30, and it is possible to adjust the position of any device.

[0096] Furthermore, in the above embodiment, the valve box 100 is formed in a circular shape in plan view, but the shape of the valve box 100 is not particularly limited. For example, the valve box 100 may be formed in a rectangular shape in plan view.

[0097] Furthermore, while the above embodiment allows for adjustment of the position of the target device in the circumferential direction CD, 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 it is also possible to 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. Thus, the direction in which the position of the target device is adjusted by the horizontal adjustment unit can be changed as appropriate.

[0098] Furthermore, in the above embodiment, the position of the target equipment is adjusted by the elongated hole 141a, the first bolt 142, etc., but the present invention is not limited thereto, and the specific structure of the position adjustment jig is not limited as long as the position of the target equipment can be adjusted. For example, it is also possible to adjust the position of the target equipment by attaching a rail member to the inner surface of the valve box body 110 and moving the target equipment along this rail member. Alternatively, for example, it is also possible to adjust the position of the target equipment by using holes of a different shape than the elongated holes 141a and 143b. For example, instead of the elongated hole 141a shown in Figure 4(b), multiple circular holes through which the shaft of the first bolt 142 can be inserted are formed in the plate 141, and the position of the target equipment can be adjusted in stages by screwing the first bolt 142 into the female threaded portion 111 through one of these multiple holes.

[0099] Furthermore, in the above embodiment, an example was shown in which the communication unit 20 is positioned directly below the hole 131 by adjusting the position of the target device in the circumferential direction CD. However, this is just one example, and it is not necessarily required to position the communication unit 20 directly below the hole 131. [Explanation of symbols]
