Fluid pipe inspection device having non-motorized displacement
A non-motorized inspection device for inspecting a fluid pipeline, includes a monitoring device capable of generating at least one representation of the pipeline, an inertial unit capable of determining orientation data relating to the inspection device, and a means for preventing distortion of the at least one representation.
1. An inspection device with non-motorized displacement for inspecting a fluid pipeline, wherein the inspection device comprises:
a monitoring device capable of generating at least one representation of the pipeline,
an inertial unit capable of determining orientation data relating to the inspection device,
a means for preventing distortion of the at least one representation, the inspection device being intended to extend locally along a first axis that is substantially at right angles to a section of the pipeline and comprising a housing encapsulating the inertial unit and supporting the monitoring device, wherein the means for preventing distortion of the at least one representation comprises at least two sets of at least three flexible guide strips distributed around the housing, each of the at least three flexible guide strips extending radially with respect to the first axis from the housing and each of the guide strips being configured to form a spot bearing on the pipeline.
2. The inspection device as claimed in claim 1 , wherein the monitoring device is a sonar and/or a camera.
3. The inspection device as claimed in claim 1 comprising a first storage means capable of storing the at least one representation and the data from the inertial unit.
4. The inspection device as claimed in claim 1 , comprising an odometer capable of determining the distance traveled by the inspection device.
5. The inspection device as claimed in claim 1 , comprising a braking device for the inspection device capable of immobilizing the inspection device at at least one predefined distance interval for a time at least equal to the time of generation of the at least one representation.
6. The inspection device as claimed in claim 1 , comprising a pipeline lighting means.
7. The inspection device as claimed in claim 1 , comprising a locating means.
8. The inspection device as claimed in claim 1 , wherein the at least three guide strips of each of the at least two sets are uniformly distributed around the housing.
9. The inspection device as claimed in claim 1 , further comprising a comparator comparing the data from the inertial unit with predefined data relating to the pipeline so as to process the at least one representation.
