Description

  The present invention relates to a piping connection structure for devices in which adjacent devices are connected by piping.

  Conventionally, a sensor array system including a plurality of types of sensors has been known, and the sensor array system includes a plurality of types of gas sensors for identifying and detecting a plurality of types of gases as sensors, or on the spot according to the environment. In order to detect changes in the external environment, an oxygen sensor, a CO sensor, a city gas sensor, an LP gas sensor, and the like were provided.

  The sensor array system has sensor units (an example of equipment) provided with each sensor inside, and each sensor unit is connected by, for example, piping, and the sensor unit on the downstream side in order from the sensor unit on the upstream side. The atmospheric gas in the environment was allowed to flow down, and changes in the external environment were detected by sensors provided in the respective sensor units.

  Note that the above-described sensor array system, which is a conventional technique in the present invention, is a general technique, and thus does not show any prior art documents such as patent documents.

  The piping connected to the sensor unit is inserted into one end of the locking hole formed in the sensor unit and the other end is inserted into the locking hole formed in the adjacent sensor unit. Was connected to the sensor unit.

  Here, when the sensor array system includes, for example, five sensor units, when exchanging the central sensor unit, the central sensor is released after disconnecting the tube connected to the central sensor unit. The unit needs to be removed. In this case, the connection of the tube connected to the central sensor unit cannot be released unless the sensor unit adjacent to the central sensor unit is removed. Therefore, when removing the target sensor unit, it is necessary to remove all or adjacent sensor units, which is complicated.

  Accordingly, an object of the present invention is to provide a pipe connection structure for equipment in which the target equipment can be easily removed.

Sensor array system according to the present invention for achieving the above object, provided adjacent a plurality of sensor units, a sensor array system that connects with what adjacent sensor units in the piping, its first feature structure, the sensor unit, a locking hole to be connected to the pipe, each formed on an upstream side and a downstream side, deeply formed towards the locking hole of the downstream side of the engagement hole portion of the upstream side, In the adjacent sensor unit, the downstream locking hole part of the upstream sensor unit and the upstream locking hole part of the downstream sensor unit are connected by the pipe, and the pipe is connected to the downstream side. It is in the point which connected in the state which can be moved inside a locking hole part.

According to this configuration, for example, in a pipe connecting a predetermined sensor unit and an adjacent sensor unit , one end of the pipe is connected to the locking hole on the upstream side of the predetermined sensor unit , and the other end of the pipe is adjacent. Connect to the locking hole on the downstream side of the sensor unit . At this time, the piping is connected with a margin in a state where it can move within the locking hole on the upstream side and the locking hole on the downstream side.

  At this time, the pipe is configured so as not to be disengaged from the deeply formed locking hole when the pipe is engaged deeply into the shallowly formed locking hole.

For example, when replacing the predetermined sensor unit, it is necessary to remove the predetermined sensor unit after releasing the connection pipe connected to the predetermined sensor unit. In this case, since the pipe is connected in a state of being movable inside the upstream side locking hole part and the downstream side locking hole part, the pipe is directed toward the deeply formed locking hole part. Can be moved by sliding. At this time, the sliding movement amount of the pipe inside the locking hole portion formed deeply can be made larger than the sliding movement amount of the pipe inside the locking hole portion formed shallowly. Therefore, if the amount of slide movement of the pipe inside the deeply formed locking hole is larger than the amount of slide movement of the pipe inside the deeply formed locking hole, the pipe is formed shallow. The connection with the existing locking hole can be released.

Thus, when replacing the predetermined sensor unit, the connection with the pipe connected to the predetermined sensor unit, it is possible to simply easily released for sliding the pipe, conveniently a predetermined sensor unit Can be removed. At this time, it is not necessary to remove a sensor unit adjacent to a predetermined sensor unit or all sensor units .

In this configuration, the downstream side locking hole part is formed deeper than the upstream side locking hole part.

According to this configuration, for example, when a fluid flows down the pipe, the direction in which the fluid flows down is the direction from the locking hole on the upstream side to the locking hole on the downstream side. When the fluid flows down, there is a possibility that, for example, the pipe moves in the fluid flowing direction due to the flow of the fluid. At this time, for example, the piping slides to the back of the locking hole on the upstream side of the sensor unit adjacent to the downstream side and stops. If the downstream side locking hole part is formed deeper than the upstream side locking hole part as in this configuration, the upstream side locking hole part is formed shallower (upstream side engaging hole part). The stop hole portion is a shallow locking hole portion, and the downstream locking hole portion is a deep locking hole portion).

As mentioned above, the piping is formed shallowly (even if it is inserted deeply into the upstream locking hole portion of the sensor unit adjacent to the downstream side), the downstream locking hole is formed deeply. It is configured so that it does not come off the part. For this reason, even if the pipe moves in the fluid flow direction due to the fluid flow, the pipe slides to the depth of the upstream locking hole formed in the shallow sensor unit on the downstream side and stops. The piping is not detached from the locking hole on the downstream side.

Therefore, with this configuration, it is possible to prevent the pipe from coming off from the upstream locking hole portion formed shallowly at times other than when the predetermined sensor unit is replaced.
The 2nd characteristic structure of the sensor array system which concerns on this invention exists in the point which accommodated the several sensor unit in the same housing | casing.
According to this structure, it can be set as a compact sensor array system by accommodating a several sensor unit in the same housing | casing, For example, it can be set as the aspect excellent in portability.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The present invention is a piping connection structure for devices in which adjacent devices are connected by piping, and in this embodiment, a sensor array system including a plurality of sensor units (an example of devices) having sensors for detecting changes in the external environment. The pipe connection structure will be described. The sensor array system X may be any device as long as it is a portable aspect or an aspect that is installed indoors or outdoors on a wall surface. This embodiment demonstrates the case where it is set as the aspect of portability.

  In the present embodiment, as shown in FIGS. 1 to 6, the sensor array system X will be described with respect to a case where five sensor units 10 to 50 are provided.

  Adjacent sensor units are connected by a pipe 60 through which ambient atmospheric gas flows, and a gas flow passage 70 is formed for flowing ambient atmospheric gas from the upstream sensor unit 10 to the downstream sensor unit 50 in order. The

For example, in the sensor unit 10, the sensor block 11 is formed with a locking hole portion connected to the pipe 60 on the upstream side where the atmospheric gas sucked from the intake port 1 flows in and on the downstream side where the atmospheric gas flows out. . That is, the sensor block 11 is formed with an upstream side locking hole portion 11a into which atmospheric gas flows and a downstream side locking hole portion 11b from which atmospheric gas flows out. In the said upstream side locking hole part 11a and the downstream side locking hole part 11b, each connects with the 1st piping 61 and the 2nd piping 62 (FIG. 5).
The pipe 60 is locked in the locking hole by the O-ring 16.

  The sensor unit 10 is supported by a sensor block 11, and detects a sensor 12 that detects a change in the external environment, a flow sensor 13 that measures the flow rate of the atmospheric gas, a sensor buffer 14 that buffers the atmospheric gas, and sucks the atmospheric gas. A pump 15 is provided. The atmospheric gas that has flowed into the sensor block 11 passes through the branch path 71 branched from the gas flow path 70 and flows into the sensor 12, and flows down through the flow sensor 13 and the sensor buffer 14.

  The other sensor units have the same configuration, that is, the sensor unit 20 includes a sensor block 21, a sensor 22, a flow sensor 23, a sensor buffer 24, and a pump 25. The sensor block 21 includes an upstream side locking hole 21a and a downstream side. A locking hole 21b is formed. The second piping 62 is connected to the upstream locking hole 21a, and the third piping 63 is connected to the downstream locking hole 21b.

  The sensor unit 30 includes a sensor block 31, a sensor 32, a flow sensor 33, a sensor buffer 34, and a pump 35, and an upstream locking hole 31 a and a downstream locking hole 31 b are formed in the sensor block 31. A third pipe 63 is connected to the upstream side locking hole 31a, and a fourth pipe 64 is connected to the downstream side locking hole 31b.

  The sensor unit 40 includes a sensor block 41, a sensor 42, a flow sensor 43, a sensor buffer 44, and a pump 45, and an upstream locking hole 41 a and a downstream locking hole 41 b are formed in the sensor block 41. The fourth pipe 64 is connected to the upstream side locking hole 41a, and the fifth pipe 65 is connected to the downstream side locking hole 41b.

  Further, the sensor unit 50 includes a sensor block 51, a sensor 52, a flow sensor 53, a sensor buffer 54, and a pump 55, and an upstream locking hole 51a and a downstream locking hole 51b are formed in the sensor block 51. The fifth pipe 65 is connected to the upstream side locking hole 51a. Since the sensor unit 50 is the most downstream unit, the downstream locking hole 51b may be configured so that the atmospheric gas does not flow downstream. Therefore, the downstream side locking hole 51b may be sealed, and the downstream side locking hole part may not be provided.

The atmospheric gas that has flowed into the sensor blocks 21 to 51 passes through the branch paths 72 to 75 branched from the gas flow path 70 and flows into the sensors 22 to 52, respectively, and flows through the flow sensors 23 to 53 and the sensor buffers 24 to 54, respectively. Flow down.
It is possible to output a signal including information such as the flow rate from the flow sensors 23 to 53. At this time, monitoring is performed by connecting to an external device that can receive the signal and display information such as the flow rate. Thus, clogging of piping due to dirt or the like, failure of the pump unit, etc. can be detected at an early stage.

  The atmospheric gas discharged from the pumps 15 to 55 is discharged from the exhaust port 2 to the outside of the sensor array system X via the out buffer 80.

  Each of the sensor units 10 to 50 includes sensors 12 to 52 that detect changes in the external environment. As such a sensor, a gas sensor such as an oxygen sensor, a CO sensor, a city gas sensor, and an LP gas sensor can be used, but is not limited thereto.

  The gas sensor may be in any form as long as it detects the gas to be detected. For example, an oxygen sensor can detect oxygen gas, a CO sensor can detect carbon monoxide gas generated by incomplete combustion, and a city gas sensor can detect a leak gas such as hydrocarbon gas. A semiconductor sensor element, a contact combustion sensor element, an electrochemical sensor, and the like can be used.

  The sensor array system X receives an alarm signal from the calculation means when a later-described calculation means (not shown), for example, determines that the sensor 12 continuously detects the gas to be detected that is higher than or equal to the alarm level. It is connected with the sound emission part (not shown) which emits. The sound emitting unit may be incorporated in the sensor array system X.

The calculation means includes a concentration calculation unit (not shown) that calculates the detected gas concentration based on the output of the sensor 12 that detects the detected gas. Further, when the sensor 12 continuously detects the detected gas concentration equal to or higher than the alarm level, the calculation means controls to transmit an alarm signal to the sound emitting unit and issue an alarm by the sound emitting unit.
In the sensor array system X of the present invention, a display unit (not shown) for displaying the result of the calculation means may be provided in the housing so that the detected gas concentration and the like can be displayed.

  In the pipe connection structure of the sensor array system X of the present invention, for example, in the sensor block 11 of the sensor unit 10, one of the upstream side locking hole part 11a and the downstream side locking hole part 11b is formed deeper than the other. (FIG. 5). In this case, also in the sensor blocks 21 to 51 of the other sensor units 20 to 50, any one of the upstream side locking hole portions 21a to 51a and the downstream side locking hole portions 21b to 51b is formed deeper than the other. In the present embodiment, a case in which the locking hole portion on the downstream side of the gas flow passage 70 is formed deep will be described. That is, in the sensor blocks 11 to 51, the downstream side locking hole parts 11b to 51b are formed deeper than the upstream side locking hole parts 11a to 51a.

  For example, in the second pipe 62 connecting the sensor unit 10 and the sensor unit 20, one end of the second pipe 62 is connected to the downstream locking hole 11 b of the sensor block 11, and the other end of the second pipe 62 is the sensor block. 21 is connected to the upstream side locking hole 21a. At this time, the second pipe 62 is connected with a margin in a state where it can move within the upstream side locking hole part 21a and the downstream side locking hole part 11b.

  The second pipe 62 may be in any form as long as it is connected with a margin while being movable within the upstream side locking hole part 21a and the downstream side locking hole part 11b. For example, the second pipe 62 does not engage with any one of the upstream side locking hole part 21a and the downstream side locking hole part 11b, or the upstream side locking hole part 21a and the downstream side locking hole part. It can be set as the aspect which does not engage in the back of both of 11b. At this time, the second pipe 62 is configured so as not to be disengaged from the deeply formed downstream side locking hole portion 11b when the second piping 62 is engaged to the depth of the upstream side locking hole portion 21a formed shallow.

  For example, when replacing the sensor unit 20, it is necessary to remove the sensor unit 20 after releasing the connection between the second pipe 62 and the third pipe 63 connected to the sensor unit 20. In this case, since the second pipe 62 is connected in a state of being movable within the upstream side locking hole part 21a and the downstream side locking hole part 11b, the downstream side connection of the sensor block 11 formed deeply. It can slide and move toward the blind hole portion 11b. At this time, the sliding movement amount of the second pipe 62 inside the downstream side locking hole part 11b that is formed deeply is the same as that of the second pipe 62 inside the upstream side locking hole part 21a that is formed shallowly. It can be made larger than the amount of slide movement. Therefore, the sliding movement amount of the second pipe 62 inside the downstream side locking hole part 11b that is formed deeply is a slide of the second pipe 62 inside the upstream side locking hole part 21a that is formed shallowly. If it becomes larger than the moving amount, the second pipe 62 can be disconnected from the upstream side locking hole 21a formed shallow (FIG. 6).

  On the other hand, the third pipe 63 connected to the sensor unit 20 is also connected with a margin so as to be movable inside the upstream side locking hole part 31a and the downstream side locking hole part 21b. Accordingly, the third piping 63 can be slid toward the downstream side locking hole 21b of the sensor block 21 in which the third piping 63 is formed deep, and the third piping 63 is upstream of the sensor block 31 in which the third piping 63 is formed shallow. The connection with the side locking hole 31a can be released.

  Thus, when exchanging the sensor unit 20, it is easy to connect the second pipe 62 and the third pipe 63 connected to the sensor unit 20 simply by sliding the second pipe 62 and the third pipe 63. Since it can cancel | release, the sensor unit 20 can be removed easily. At this time, it is not necessary to remove the sensor unit 20 adjacent to the sensor unit 20 or all the sensor units. Further, if the connection between the second pipe 62 and the third pipe 63 can be released, only the sensor block 21 or only the flow sensor 23 can be replaced, and only the members that need to be replaced can be easily replaced as appropriate.

  As described above, in the present embodiment, the downstream side locking hole portions 11b to 51b are formed deeper than the upstream side locking hole portions 11a to 51a.

  The direction in which the atmospheric gas flows down the gas flow passage 70 is the direction from the upstream locking hole 11a to the downstream locking hole 11b. When the atmospheric gas flows down the gas flow passage 70, for example, the pipe 60 may move in the flowing direction of the atmospheric gas due to the flow of the atmospheric gas. At this time, for example, the second pipe 62 slides to the back of the upstream side locking hole 21a of the sensor block 21 adjacent to the downstream side and stops. If the downstream side locking hole part 11b is formed deeper than the upstream side locking hole part 21a as in this configuration, the upstream side locking hole part 21a is formed shallower.

  As described above, the second piping 62 is shallowly formed (the downstream side of the sensor block 21 adjacent to the downstream side) is deeply formed even if the second piping 62 is engaged to the depth of the upstream side locking hole portion 21a. It is comprised so that it may not remove | deviate from the latching hole part 11b. Therefore, even if the second pipe 62 moves in the downward direction of the atmospheric gas due to the atmospheric gas flow, the second piping 62 is formed in the upstream side locking hole portion formed shallower in the sensor block 21 adjacent to the downstream side. It only slides to the back of 21a and stops, and the second piping 62 does not come off from the downstream side locking hole 11b.

  Therefore, if it is this structure, it will not remove | deviate from the upstream latching hole parts 11a-51a in which the piping 60 is shallowly formed except when replacing the sensor units 10-50.

In addition, you may comprise so that a thread groove may be formed in the upstream side locking hole parts 11a-51a currently formed shallowly, and the piping 60 may be screwed in in the upstream side locking hole parts 11a-51a. At this time, since the pipe 60 cannot slide with respect to the upstream side locking hole parts 11a to 51a, it is difficult to be displaced with respect to the upstream side locking hole parts 11a to 51a, and the upstream side locking hole parts 11a to 11a. It can prevent beforehand that it remove | deviates from 51a.
Moreover, it can prevent beforehand that the piping 60 remove | deviates from the upstream latching hole parts 11a-51a by providing the connection member which connects the flow side latching hole parts 11a-51a and the piping 60. FIG.

  INDUSTRIAL APPLICABILITY The present invention can be used for a connection structure for devices in which adjacent devices are connected by piping.
