    BACKGROUND OF THE INVENTION The invention relates to the general field of fluid distribution, and it relates particularly to the installation of electronic devices in the pipelines in which natural gas circulates. The invention finds particular application in the installation of electronic devices in pipes of polyethylene or polyvinyl chloride (PVC), or in any other plastic material adapted for the circulation of fluids.
    New, cleaner and renewable sources of energy are now available. Biomethane is one of these sources of energy. Biomethane is obtained by fermentation of agricultural waste, household waste, industrial waste or sewage sludge. Biomethane can be purified to a quality corresponding to the properties that allow it to be injected into a natural gas network. More precisely, this gas is odorized, controlled, and its pressure is regulated and then injected into a natural gas distribution network for delivery to consumers. Whereas traditionally, the distribution of natural gas is done in a descending tree structure, the distribution of natural gas must now be done in a mesh structure because of the multiplication of the points of distribution of biomethane.
    In such a mesh structure, it is particularly important to know how the gas circulates, in particular to adapt the production needs according to the consumption. This flow knowledge can be obtained by measuring the pressure, the flow rate, and the physicochemical parameters of the natural gas at numerous measurement points. To obtain a precise knowledge of flows, it is necessary to use a large number of measurement points. This leads to a good knowledge of the gas quality, its pressure, and the integrity of the structure. This also makes it possible to properly control the structures of the structure and then optimize billing with the customers who receive the gas.
    Sensors (for example pressure or flow) are traditionally installed in pipes or at so-called expansion stations. However, the places where you want to take measurements are not always accessible to implement work for the installation of sensors.
    These technical disadvantages have an impact on the cost and the duration of the interventions in which the sensors are installed.
    Another disadvantage of the known techniques concerns the need to cut off the flow of gas in the pipes during the interventions.
    In a first known method of intervention, a pipe is pierced in which gas circulates using an isolation lock or apparatus for piercing a pipe in which a gas circulates, and then an electronic system such as a sensor in the pipeline.
    In a second known method of intervention, the electronic system is introduced by means of a probe.
    These known methods have the following drawbacks: - installation work may require a cut in the flow of gas or at least a drop in the pressure in the pipe, - the traditional electronic systems are very bulky (for example between 1 meter and 1.5 meters high), which makes them installed only in sufficiently accessible places, - traditional electronic systems require external power supply: this implies that measurements can only be made near a source of power. compatible with the European directive well known to those skilled in the art "ATEX", - the traditional electronic systems communicate the recovered information (if it is sensors) by wired networks, - the cost of traditional electronic systems is too high, and this is also the case with the costs of installing these systems: this prevents the installation of many sensors.
    It may be noted that for an electronic system installed in a pipe does not interfere with the flow of fluid, this installation must be in a straight pipe between two ends at a specific point. This point is chosen so that the ratio between the distances between the two ends and the point is controlled (this ratio depends on the diameter of the pipe). This constraint further limits the possibilities of installation of a system according to the prior art. The invention aims to overcome some of these disadvantages, and it aims in particular to obtain a small device, easy to install, and can be inserted into a pipe in which a fluid flows.
    Object and summary of the invention
    The present invention responds to this need by proposing an electronic device intended to be inserted in a pipeline to a final position, the device being further configured to be arranged, prior to said insertion in said final position, in a sleeve assembled to the duct and through a conduit of the sleeve opening on a wall of the pipe, the device comprising: a body provided with a threaded portion intended to cooperate with a threaded portion of the pipe of the sleeve to move the electronic device by screwing up at its final position, a punch formed to form a through hole in the pipe during said screwing and allow the insertion of the electronic device in the pipe to its final position, an electronic module disposed between the die and said body and intended to be in contact with a fluid passing through the channel isation in said final position, • at least one electrical connection connected to the electronic module and passing through said body opening on an upper face of the body located opposite said electronic module and said punch relative to said body, the body and said minus an electrical connection forming a plug of the pipe of the sleeve.
    Thus, the invention provides a device for simultaneous insertion and piercing of the pipe and implemented while maintaining a good seal. It is therefore not necessary to use an airlock to maintain the seal, and there is also no drilling and insertion in two separate stages.
    This results from the structure of the device which comprises both a punch and a threaded portion which will cooperate with that of the pipe of the sleeve to maintain a seal. The use of the threaded portion and a body which is full provides a good seal for pressure ranges that the skilled person can determine. For certain applications, the seal can be obtained not only by the cooperation of the threaded portions, but also by the use of an airlock, as will be described below. The installation of the device as defined above is therefore particularly easy, since this installation can be made when the pipe is accessible and a sleeve can be assembled on a pipe, with a pipe that has an opening that opens on a wall (the periphery of this opening being sealed to the wall).
    It may be noted that by forming a plug, it is meant that the body in which the electrical connections are embedded does not allow gas to pass into the conduit of the sleeve and form a sealed assembly by means of the cooperating threaded portions. The punch is for piercing an orifice as the device moves toward the pipe. It follows that the invention applies to pipes formed by materials that can be pierced in this way. This is the case for polyethylene pipes well suited for the implementation of the invention.
    It may also be noted that the device can be introduced into an already existing sleeve and used for the branches. These sleeves comprise a pipe with a thread and they are welded on the pipes.
    According to a particular embodiment, said upper face comprises a recess adapted to receive a screwdriver and drive the screwing said device.
    According to a particular embodiment, said upper face comprises at least one female electrical connector electrically connected to said at least one electrical connection.
    Thus, the electrical module present in the pipe may comprise only part of the electronic elements of a more complete device, for example a sensor as an electronic module.
    According to a particular embodiment, the device comprises a spacer for spacing the electronic module of said body.
    The length of this spacer will be chosen to place the electronic module at an appropriate point of the pipe, depending on the chosen application.
    According to a particular embodiment, said electrical connections extend at least along and on said spacer.
    This makes the electrical connection more robust.
    According to a particular embodiment, the device comprises walls holding said punch spaced from said body, said walls being provided with windows to allow the passage of fluid from said pipe to said electronic module when the device is in its final position.
    According to a particular embodiment, in which the electronic module is a sensor. As an indication, the sensor may be a sensor measuring a flow rate, a methane index, a pressure, a temperature, an energy, or a higher or lower heating value.
    According to a particular embodiment, said sensor is a flow meter, and said device comprises a visible indicator when screwing the device to place the device in a direction defined by the pipe (for example the axial direction of the pipe).
    According to a particular embodiment, the electronic module is a module for modifying the flow or the treatment of the fluid. The invention thus makes it possible to simply place elements of modifications of the section that act on the fluid such as inflatable balloons or diaphragms. Alternatively, processing modules such as filters can be operated.
    It is thus possible to regulate or interrupt a remote stream if the electronic device is equipped with wireless communication means.
    According to a particular embodiment, the device further comprises an element connectable to the upper face of said body configured to be electrically connected to said at least one electrical connection when the connectable element is connected to the upper face of said body, the element connectable device comprising at least one additional electronic module chosen from the group comprising: an on-board electrical energy source, a wireless communication module, a microcontroller, a switch.
    Connectable means that the connectable element can be connected and disconnected.
    It can be noted that since this connectable element comprises an on-board power source and a wireless communication module, the device can operate autonomously without a wired link with another device.
    The on-board power source can be a battery or a fuel cell.
    Also, the use of a connectable element comprising the on-board power source makes it possible to supply the electronic module once the electronic module has been put in place in its final position: this reduces the risks associated with the introduction of an electronic apparatus into a pipeline comprising gas. The use of an on-board power source also eliminates the need for a wired power supply.
    Furthermore, the use of a power source embedded in the connectable element facilitates the replacement of the on-board power source without the need to move the rest of the device which is positioned in the end position. The use of a switch allows more secure installation of the device.
    According to a particular embodiment, said upper face comprises at least one female electrical connector electrically connected to said at least one electrical connection, and the connectable element is plugable into said at least one female electrical connector. The invention also proposes a system comprising an electronic device as defined above, and at least one sleeve comprising a pipe in which the device is arranged, the pipe comprising a threaded portion cooperating with the threaded portion of the body of the device.
    According to a particular embodiment, the sleeve comprises a coupling portion arranged around an opening of the pipe of the sleeve intended to open on the pipe, the connecting portion being configured to be assembled to the pipe by welding to form a connection sealed around said opening.
    This welding may be an electrical welding, such as an electric welding used by the skilled person to assemble branch sleeves. This implies that the coupling portion comprises a heating resistor in which a current is circulated to fuse the material of the connecting portion with that of the pipe (the connecting portion and the pipe being preferably composed of the same material).
    According to a particular embodiment, the system further comprises a waterproof lock assembled on said sleeve by screwing, the airlock comprising a valve integral passage, an opening for the passage of a sealed manner of a tool in the airlock to reach said device in the sleeve and screw or unscrew said device and move it in the lock (the opening may be formed in a lock pipe arranged in the lock), the lock being configured to allow the passage on either side of the valve with integral passage of said device.
    Thus, this airlock can be used to: increase the tightness during screwing and drilling of the pipe. The seal will then be obtained by the electronic device screwed into the sleeve and the airlock, remove a device already in the final position, insert a device into a pipe having already been pierced.
    The full-flow valve will be open to allow the tool and device to pass, and it will be closed to seal when there is no longer a device and the line has been pierced by the punch. The invention also proposes a method of installing an electronic device as defined above, wherein said electronic device is arranged in a sleeve assembled to a pipe and through a conduit of the sleeve opening on the pipe, the method comprising screwing the device to move the device in the conduit of the sleeve to said final position, said punch forming, during screwing, a through hole in the pipe to allow insertion of the electronic device in the pipe.
    According to a particular mode of implementation, the device further comprises an element connectable to the upper face of said body configured to be electrically connected to said at least one electrical connection when the connectable element is connected to the upper face of said body, the connectable element comprising at least one additional electronic module chosen from the group comprising: an on-board electrical energy source, a wireless communication module, a microcontroller, a switch, the method further comprising a step subsequent to said screwing of the device in which connects the connectable element to the upper face of the body.
    In other words, the connectable element is not connected during screwing of the device.
    According to a particular mode of implementation, the method further comprises a posterior step of fixing a plug on the opening of the pipe opposite to that opening on the pipe.
    This plug may be part of a system comprising the device and the sleeve.
    The cap may include a seal. This seal provides a second sealed barrier to prevent gas release to the outside. This seal may be an O-ring.
    According to a particular mode of implementation, the method comprises the assembly of a sealed airlock on said sleeve by screwing, the sealed airlock comprising a full-flow valve, an opening for the sealed passage of a tool in the airlock to reach said device in the sleeve, the airlock being configured to allow the passage on either side of the integral flow valve of said device, said method further comprising a step of screwing the device into the sleeve by means of said tool passing through the airlock, or a step of unscrewing the device in the final position by means of said tool passing through the airlock.
    According to a particular mode of implementation, comprising said unscrewing step, the method further comprises a step in which said device is moved to the other side of the full-flow valve, and said valve is closed, or the method comprising said screwing step, the method comprises a prior step in which said valve is opened and the device is moved to the sleeve.
    According to a particular mode of implementation, the method further comprises, after said unscrewing step, a subsequent insertion of a second electronic device as defined above in which said second electronic device is placed in said sealed airlock, opens the full-flow valve, moves said second electronic device to the sleeve and screws said second device.
    In other words, this embodiment provides for the replacement of the device, for example if an on-board power source of the device is exhausted, or if the device is faulty.
    It may be noted that the method may comprise a preliminary step of assembling said sleeve on a pipe.

    Detailed description of an embodiment
    We will now describe an electronic device to be inserted into a pipe.
    In the following examples, the pipes concerned are polyethylene pipes in which natural gas circulates. The invention is nevertheless not limited to these pipes.
    In the appended figures, the same references designate the same elements.
    In Figure 1, there is shown in sectional view a device 1 for insertion into a polyethylene pipe.
    This device 1 comprises a body 2 made of metal, for example brass (alternatively, ceramic materials may be used. The body is provided on its side walls with a threaded portion 3, which is intended to cooperate with a threaded portion of a pipe of a sleeve for moving the device.
    To penetrate inside a pipe, the device comprises a punch 4 optionally formed of the same metal as the body 2, and the punch 4 is spaced from the body by walls 5. The punch has substantially the same dimensions as the rest of the device to be able to form an orifice that will let the device.
    The device comprises an electronic module 6, here a flow meter, and this electronic module 6 is arranged between the punch 4 and the body 2. To place the electronic module 6 more inside the pipe, a spacer 7 is placed between the body 2 and the electronic module 6. This spacer 2 holds the electronic module.
    Since the electronic module 6 is a sensor, other electronic elements are necessary to make it work. For this purpose, two electrical connections 8 have been arranged to connect the electronic module 6 to other electronic elements. The electronic connections 8 extend from the electronic module to the body, and they are embedded in the body 2 to open on the upper face 10 of the body 2 (the upper face being opposite the electronic module 6 and the punch 4 relative to the body 2).
    The electrical connections 8 being embedded in the body 2, the body and the electrical connections form a solid element that can act as a plug of a pipe provided with threads to cooperate with the threaded portions 3 of the device. More specifically, the electrical connections 8 open onto female electrical connections 11 at the upper face 10 of the body 2.
    To move the device 1 in a pipe, a recess 12 adapted to receive a screwdriver and drive the screwing device has been arranged within the upper face 10 of the body 2.
    FIG. 1 shows the electronic device 1 provided with a connectable element 20. This connectable element 20 here comprises a battery 21 and a wireless communication module 22. To switch on the device 1, a switch 23 is arranged on the connectable element 20. This connectable element 20 connects to the upper face of the body 2 by plugging electrical connections 24 of the element connectable with the electrical connections 11 opening on the upper face 10.
    It can be noted that the wireless communication module 22 can use any known protocol to trace information retrieved by the electronic module 6. As an indication, the wireless communication module can be used to integrate the device into a communication network cellular.
    The different components of the connectable element 20 can be arranged within one and the same printed circuit board.
    Elastic joints may be placed around the electrical connections, as shown in the figure.
    As can be seen from FIG. 1, during the screwing of the device, the recess 12 must be accessible. For this purpose the connectable element 20 is not connected during screwing but only once the rest of the device has reached its final position.
    FIG. 2 shows a system comprising a device 1 described with reference to FIG. 1 and a sleeve 30.
    The sleeve 30 comprises a pipe 31 in which the device 1 is arranged. In FIG. 1, the device 1 is shown with the connectable element 20, and it has also been shown in a position corresponding to that in which the device will be when it will be inserted into a pipeline. In fact, the device 1 can move in translation in the pipe 31. This displacement is obtained by means of a threaded portion 32 of the pipe 31, when a torque is applied by a tool in the recess 12.
    The sleeve 30 has a connecting portion 33 extending radially relative to the axis of the pipe 31 (shown in phantom). This connecting portion is intended to be assembled to a pipe. As the pipes are generally cylindrical with a circular cross-section, the connecting portion 33 may also extend in the axial direction of the pipe 31 to match the shape of the pipe.
    In an alternative not shown here, the sleeve 30 comprises another part called saddle placed opposite the connecting portion 33 and intended to surround the pipe to join the connecting portion 33, as is conventional for the known lead sleeves according to the prior art. In addition, the connecting piece 33 may comprise a heating resistor in which a current may be circulated in order to obtain a fusion of the connection portion with a pipe: this makes it possible to obtain an opening of the pipe 31 sealed by the wall of the pipe on which it opens and by the melting of the connecting portion 33 with the wall of the pipe.
    As indicated above, the device 1 is here placed in its final position, with the body 2 and the connections 8 forming a plug of the pipe 21, since the threaded portions 3 and 32 cooperate. To improve the seal, a seal 34 is placed at the opening of the pipe 31 so that the threaded portion 3 is found against the seal when the device is in its final position.
    To further improve the seal, the system comprises a plug 40 placed so as to plug the opening of the pipe opposite that which will be placed against the wall of the pipe. This plug 40 has a threaded portion configured to cooperate with a threaded portion 35 placed outside the sleeve. The plug 40 further comprises a seal 42.
    In FIG. 3A, there is shown in perspective a device 1 without connectable element. As can be seen in this figure, the device 1 has a quasi-cylindrical shape of circular section.
    The device 1 comprises windows 13 formed in the walls 5 which separate the body 2 from the punch 4. The windows 13 allow the fluid flowing in the pipe to reach the electronic module 6. It may be noted that when the Die-cutter 4 forms an orifice in a wall of a pipe, a cut portion 51 (or coupon) remains in the punch 4, it is for this reason that the windows 13 are formed. Windows 13 also limit the impact of the insertion of the device in the pipe on the flow of fluid flowing there.
    In the example of this figure, there is no spacer but the electrical connections 8 directly maintain an electronic module 6. This electronic module 6 is in a substantially horizontal position in the figure: this arrangement, possible if the module 6 electronics can work well, allows to position it more deeply in the pipeline.
    FIG. 3B shows another perspective view where the electronic device 1 has an upper face 10 having a recess 12 in the shape of a hexagon to receive a key-type tool
    Allen. The upper face 10 also comprises a female connector 11 for one or more electrical connections passing through the body 2.
    FIG. 4 shows the system described with reference to FIG. 2 assembled on a pipe 50. The pipe is a polyethylene pipe having a diameter which may be between 200 millimeters and 400 millimeters, the invention may nevertheless be implemented on pipes with other diameters. As can be seen in this figure, the device 1 and the sleeve 30 form a system having a total height close to the diameter of the pipe. The invention can therefore be made in a space-saving manner, which makes it easy to install in many points.
    FIGS. 5A to 5D show the various steps of the insertion of an electronic device 1 into a pipe 50. These figures are sectional views in a direction perpendicular to that of FIGS. 1, 2 and 4.
    In FIG. 5A, the sleeve 30 has been assembled with the pipe 50 by welding. At this stage, the device 1 is integrally arranged in the sleeve 30, and it is not provided with the connectable element.
    A tool 100 is then used to screw the device 1 which pierces an orifice in the pipe 50 (Figure 5B). The piercing can be performed while a gas flows in the pipe, since the body of the device through which the electrical connections act acts as a plug in the sleeve 30.
    The screwing continues until the device 1 is moved into the pipe 50 in its final position, and the connectable element 20 can then be connected to the rest of the device 1 (FIG. 5C).
    Then, one can put a plug 40 on the sleeve 30, as shown in Figure 5D.
    It may be noted that it is also possible to use an additional airlock to install or remove the device while a fluid is circulating in the pipeline. This can replace an already installed device.
    FIG. 6A represents a variant of the invention in which the electronic module 60 is a module for modifying the section of the pipe comprising an inflatable element. The activation of this electronic module 60 is shown in FIG. 6B, where the inflatable element has been inflated.
    The system shown in FIGS. 6A and 6B simply and remotely controls flow in a pipeline network.
    We will now, with reference to Figures 7A to 7E, describe the various steps of the insertion of a device in a pipe using an airlock.
    In FIG. 7A, there is shown a system similar to that described with reference to FIG. 5A, but in which the system further comprises a first portion of lock 70 provided with an integral-passage valve 71. The first part of airlock 71 is screwed onto the sleeve in place of a plug such as the cap 40 described with reference to Figure 5D.
    FIG. 7B shows the assembly of a second portion of lock 72 on the first part of airlock 70, the two parts of airlock 70 and 72 forming the airlock with an airlock conduit 74. In the example of FIG. 7B, the integral flow valve 71 is in an open or running position, and a tool 73 has been sealingly inserted into the airlock duct 74 housed in the airlock sections 70 and 72, and the tool thus passes through. in the airlock. The tool 73 cooperates with the electronic device and can cause its screwing.
    A tool 100 may be used on the portion of the tool 73 which protrudes in a sealed manner from the second lock portion 72 (Fig. 7C). This causes the device 1 to be screwed into the sleeve 30 and inserted into the pipe 50. The airlock makes it possible to obtain a good seal when the device 1 is inserted into the pipe 50.
    FIG. 7D shows the placement of a connectable element 20, and FIG. 7E shows the placement of a plug 40 on the sleeve 30. The connectable element 20 comprises at least one source of embedded electrical power, a wireless communication module, a microcontroller, or a switch. This connectable element 20 is connected only after the piercing of the pipe.
    With reference to FIGS. 8A to 8E, the removal of an electronic device using an airlock will now be described.
    In FIG. 8A, there is shown a device 1 inserted in a pipeline such as the device obtained in FIG. 5D but in which the connectable element 20 has already been removed. In place of the plug of FIG. 5D, a first portion of lock 70 is assembled to the sleeve. The integral flow valve 71 is initially closed.
    In FIG. 8B, there is shown the assembly of a second portion of lock 72 and the opening of the integral passage valve 71.
    FIG. 8C shows the insertion of a tool 73 in a sealed manner into the airlock duct 74 housed in the first and second parts of airlock 70 and 72 until reaching the device 1. A tool is also used. 100 to unscrew the device 1.
    In Figure 8D, there is shown the device 1 out of the pipe having been pierced.
    The device is then moved into the second portion of airlock 72 and the integral flow valve 71 is closed (FIG. 8E): the seal is thus maintained even if the second airlock portion is disassembled to recover the device 1.
    In one embodiment of the invention, the tool 73 is sufficiently tight in the device 1 (for example in a recess of the device 1) so that the displacement is implemented in the following manner: the device is unscrewed and goes back in the sleeve 30, once out of the sleeve, it is because it is clamped in the device 1 that the tool 73 moves the device 1 in the pipe by moving the tool 73.
    Alternatively, the device 1 comprises a recess equipped with a bayonet fixing system for fixing the tool 73 to the device 1 (not shown). The displacement is implemented as follows: the device is unscrewed and reassembled in the sleeve 30, once out of the sleeve, it is by means of the bayonet attachment that the movement of the tool 73 drives that of the device that goes back to in the conduct of airlocks 74.
    This can remove a device whose onboard power source is exhausted or a faulty device.
    It will also be possible to insert a second device for implementing a replacement, in a pipe that has already been pierced. The invention therefore makes it possible to simply insert small electronic devices in pipes, including when a fluid circulates in the pipe.
