- the invention aims to overcome all or part of the problems mentioned above by proposing a non-motorized sounder can evolve in any type of pipeline, even small diameter (400 mm to 1600 mm), and having the ability to detect deformations or structural deteriorations of the pipe as well as to evaluate the possible fouling.
- the proposed invention makes it possible, on the one hand, to generate representations of the channel (sonar data and / or visual data) and, on the other hand, to determine the locations of the channel where the representations have been generated in order to be able to process and analyze the collected data.
- the subject of the invention is a device for non-motorized inspection of a fluid channel, comprising a monitoring device capable of generating at least one representation of the pipe, an inertial unit able to determine data of orientation of the inspection device, an anti-deformation means of the at least one representation.
- the inspection device can thus evolve in a waste water pipe and ensure the obtaining of a representation without deformation of the pipe.
- the monitoring device may be a sonar and / or one or more camera (s).
- a representation of the pipe is a sound image.
- a representation of the pipe is a visual datum (image or video).
- the inspection device comprises a first storage means capable of storing the at least one representation and the data of the inertial unit.
- This embodiment requires no cable or wireless network to transmit the collected data. It represents an economical, robust and powerful solution.
- the inspection device comprises an odometer able to determine the distance traveled by the inspection device. It is thus possible to associate each representation with a well defined place in the pipeline.
- the inspection device comprises a brake device of the inspection device able to immobilize the inspection device at least a predefined distance interval for a duration at least equal to the duration of the generation of the at least one representation. This makes it possible to keep the inspection device stationary in desired locations for the time to generate a complete representation.
- the inspection device comprises a lighting means of the pipe.
- the lighting means plays a role of light emitter ensuring better representations in the dark pipe.
- the inspection device comprises a tracking means.

- the inspection device is intended to extend locally along a first axis substantially perpendicular to a section of the pipe and comprises a housing encapsulating the inertial unit and supporting the monitoring device, and the anti-deformation means of the at least one representation comprises at least two sets of at least three strips distributed around the housing, each of the at least three strips extending radially relative to the first axis from the housing. These sets of strips allow to stabilize the inspection device in the pipe, and, depending on the length of the strips at a distance from the edges of the pipe.
- the at least three strips of each of the at least two sets are uniformly distributed around the housing. This results in an optimal positioning of the inspection device parallel to the axis of the pipe. This makes it possible to obtain a representation without deformation.
- the at least three strips of each of the at least two sets are flexible. The flexibility of the strips makes it possible both to maintain the inspection device at a certain distance from the edges of the pipe, advantageously at the center of the pipe, and not to block the inspection device in its evolution in the pipe in case partial obstruction or reduction of the diameter of the latter. The flexibility of the strips also allows any waste not to hang on the strips, they slide along the strips.

With the odometer, it is possible to associate each representation 13 with a well-defined place in the pipe 1 1.
- the inspection device 30 may comprise a brake device 35 of the inspection device 30 adapted to immobilize the inspection device 30 at least a predetermined distance interval for a duration at least equal to the duration of the generation of the device. at least one representation 13.
- the brake device 35 may be an on-board device on the inspection device, or, as in the embodiment shown in FIG. 3, a device located outside the pipe, for example on a tripod or other support. The brake device 35 makes it possible to keep the inspection device 30 stationary in desired locations for the time to generate a complete representation 13.
- the brake device 35 may be an automatic brake device with recording of the distance traveled by the inspection device 30.
- the brake device 35 may be configured so as to lock the winder of the rope 23, automatically at regular intervals, for example every 30 cm, so that the inspection device 30 is stationary and has the time to generate a representation 13, for example to make a 360 degree complete sonar acquisition at the same position in the case of a rotating sonar.
- the distance corresponding to this position and measured by the odometer 31 is recorded during automatic stops of the inspection device 30.
- the invention applies similarly with a continuous record of the distance to overcome the automatic stops of the inspection device 30.
- the representation 13 is degraded: for example sonar acquisitions would be incomplete since we would not have a 360-degree sonar image at a given position, but this operation remains possible.
- the odometer 31 is associated with a recording system in order to be able to connect the representations 13 (for example sonar data) and the data of the inertial unit 14 with the distance data of the odometer 31.
- the representations 13 and the data of the inertial unit 14 are not assembled together.
- a computer embedded in the inspection device generates a time-stamped file for each sensor (that is, a timestamped file for the sonar, a timestamped file for the inertial unit, a camera-timestamped file). ) and he records them.
- Odometer 31 generates a timestamped distance file. Subsequently, with the use of an analysis software, all these data are displayed coherently (synchronized thanks to the timestamp of the files).
- the inspection device may be equipped with an internal clock system. The data of the inertial unit 14 and the representations 13 are each recorded according to the timestamp and then read synchronously.
- Figure 4 schematically shows another embodiment of a non-motorized inspection device 40 of a fluid line according to the invention.
- the inspection device 40 shown in FIG. 4 comprises the same elements as the inspection device 30 shown in FIG. 3.
- the anti-deformation means 18 of the at least a representation 13 comprises a comparator 51 of the data of the inertial unit 14 with predefined data of the pipe 1 1 so as to process the at least one representation 13.
- the comparator 51 can be on board the inspection device 40 (as shown here), but it can also be unembarked, on a support outside the pipe 1 1.
- the principle of the inertial unit 14 is as follows.
- the inertial unit 14 measures the orientation. It does not measure a position with GPS coordinates. This orientation is expressed as the three Euler angles (each expressed in degrees): pitch 48, yaw 47 and roll 49 (see reference in FIG. 2).
- the reference for the inertial center is magnetic north (the three angles are then equal to 0).
- the yaw and pitch angles measured by the inspection system must be compared with the pitch and yaw angles of the pipeline (they can be calculated theoretically from planes of the structure or measured on site if the configuration of the site allows it). In the case of a siphon, the angles will be different on each of the three portions of the work. For each sonar acquisition, it is necessary to compare the yaw and pitch angles of the inspection device with those expected for this portion of the pipeline. If the deviation is too large (compared to a threshold value predetermined by tests), then the sonar image is to be invalidated or corrected. Similarly, it is necessary to determine the orientation of the defects to exploit the sonar data. The roll angle allows to know the orientation of the inspection device, and therefore the defects (fouling, root, etc.), with respect to the base and the vault of the pipe.
- the comparator 51 can compare the data acquired by the inertial unit 14 and the orientation data of the channel 11 (data which can be theoretical, from plans or entered by a user according to a prior initialization in the field) to determine whether the inspection device 40 is parallel to the axis of the pipe 1 1. If the inspection device 40 is not parallel to the axis of the pipe, the generated representation 13 is deformed. With the comparator 51, it is possible to know if the representation 13 generated is deformed. If this is the case, the user can reprocess the representation 13 based on the data acquired by the inertial unit 14 to perform the postprocessing of the representation 13.
- FIG. 5 represents a view from behind (to the left of the figure) and a view from above (to the right of the figure) of another embodiment of a non-motorized inspection device 50 of a fluid line. according to the invention.
- the inspection device 50 shown in FIG. 5 comprises the same elements as the inspection device 30 shown in FIG. 3. In FIG. 5, if it is considered that the inspection device 50 is intended to extend locally.
- the anti-deformation means 18 comprises at least two sets of at least three strips 42 distributed around the housing 41, each of the at least three strips 42 extending radially with respect to the first axis 19 from the housing 41. These sets of strips 42 make it possible to stabilize the inspection device 50 in the pipe 11. Depending on the length and positioning of the strips 42 around the housing 41, the inspection device 50 is stabilized at a distance from the edges of the pipe and advantageously centered in the pipe. This makes it possible to obtain a representation without deformation.
- the at least three strips 42 of each of the at least two sets are preferably uniformly distributed around the housing 41 to allow better stability of the inspection device 50, and preferably positioned at the same level, as in FIG. 5. As shown, at least one set of strips 42 is positioned at the front of the inspection device, and at least one set of strips 42 is positioned at the rear of the inspection device (front and rear being defined in relation to the first axis 19). Thus, the inspection device 50 is kept stable, at a predefined distance from the edges of the pipe and parallel to the axis 19 of the pipe 11.
- the at least three strips 42 of each of the at least two sets are flexible and each of the strips is configured to form a point support on the inner wall of the pipe.
- the strips 42 are rigid enough to hold the inspection device 50 in place. its position in the pipe 1 1 and sufficiently flexible to bend in contact with an obstacle in the pipe, as shown in dotted line to the right of Figure 5 (the arrow referenced 43 indicates the direction of movement of the inspection device 50 in Line 1 1).
- the flexibility of the strips 42 makes it possible both to maintain the inspection device 50 at a distance from the edges of the pipe 1 1, advantageously at the center of the pipe 1 1, and not to block the inspection device 50 in its evolution in line 1 1 in the event of partial obstruction of line 1 1.
- the punctual support of the strips against the inner wall of the pipe allows a better agility in the pipeline in the presence of curvatures of the pipe.
- This anti-deformation means 18 ensures the mobility of the inspection device in the pipeline despite the obstacles present in the wastewater.
- the generated representation 13 is not deformed since the measurement sonar data is stable, parallel to the axis of the pipe and well centered. It is thus possible to obtain representations 13 such as sonar images of good quality without making adjustments sonar during inspection of the pipeline.
- the inspection device is connected to a surface computer on the surface, using a cable (type waterproof Ethernet cable with waterproof plug), the sounder is lowered into the pipe. It is then possible to view the sonar images on the field computer, and adjust the sonar (especially the two parameters of gain and range) until a clear sonar image without echoes. Once this adjustment is made, the Ethernet cable is removed, the plug is obscured (for example by a plug), and only after, the inspection can begin, without any subsequent adjustment during the inspection.
- a cable type waterproof Ethernet cable with waterproof plug
