Current generation device for pipeline

A device for generating an electrical current intended to form a part of a pipeline for the circulation of a fluid, the device comprising:

• a pipe element,
• a rotor suitable for being set in motion by the fluid upon passage of the fluid into the device, and
• a stator arranged to cooperate with a radial end of the rotor opposite to an axis of rotation of the rotor in order to generate the electrical current upon said motion,
• the axis of rotation of the rotor being rotatably mounted at its opposing longitudinal ends on a first support and a second support each linked to the pipe element,
• wherein the stator comprises at least one ring arranged on one side of the rotor, and each ring comprises a circuit suitable for generating all or part of the electrical current when it is excited by at least one magnetic element of the rotor,
• wherein the rotor comprises an impeller portion configured for interacting with the fluid and a radial portion configured for interacting with the stator for generating the electrical current, the impeller portion and the radial portion being mounted on the axis of rotation at a location placed longitudinally between the first support and the second support,
• wherein at least one of the first support and the second support comprises a system or setting a distance separating the first and second supports, wherein the system comprises a setting member having a surface of contact of the support with one of the longitudinal ends of the axis of rotation of the rotor, wherein the surface of contact is translatable in a longitudinal direction.
