Abstract
A turbine (1) for a conduit comprising a turbine unit (13) including a rotor (3), characterized in that the turbine (1) comprises a speed limiting device for said turbine unit (13), which device comprises at least one flexible element (4) connected to the turbine unit (13), so as to limit the flow rate of the fluid passing through the rotor (3) in order to limit the rotational speed of the rotor (3) of the turbine unit (13).
Claims15
An electricity generation turbine for a conduit, comprising:
- a turbine unit including a rotor, and
- at least one flexible element,
- wherein the at least one flexible element is connected to the turbine unit, so as to limit a flow rate of fluid passing through the rotor in order to limit a rotational speed of the rotor of the turbine unit, and
- wherein the turbine unit comprises a non-rotating part encompassing a stator of a generator, disposed in an annular configuration, the at least one flexible element being connected to the non-rotating part,
- wherein the connection of the at least one flexible element with the turbine unit is so that the thrust generated by the fluid on the turbine unit is able to cause the turbine unit to move against the at least one flexible element if the thrust of the fluid exceeds a predefined threshold, and
- wherein the turbine unit is translationally movable along a flow axis of the fluid, coinciding with a longitudinal axis of the turbine.
