Abstract
The present device provides an in-pipe turbine generator having a conduit, a plurality of runner blades positioned within the conduit, and a pitch adjustment mechanism whereby the pitch of the runner blades may be varied. The pitch adjustment mechanism further includes pitch adjustment screws that are positioned on a tangential flat on the master pitch adjustment bevel gear. Rotation of the pitch adjustment screw rotates the master pitch adjustment bevel gear thereby rotating the blade hub gears and the runner blades. Runner blade torque and angular velocity is transferred to a DC power generator and may be converted to AC power.
Claims3
An in-pipe turbine generator comprising:
- a) a conduit;
- b) a plurality of runner blades positioned within the conduit;
- c) a pitch adjustment mechanism positioned within the conduit and accessed through a port whereby the pitch of the runner blades may be optimized for a specific in-pipe turbine generator application by adjusting at least one pitch adjustment screw;
- d) a means for imparting kinetic energy to the runner blades creating torque and angular velocity comprising the passage of a fluid through the conduit;
- and
- e) a means for transferring torque and angular velocity to a DC power generator comprising a generator coupling, a gearbox reduction means, a DC generator, and a means for supporting the gearbox reduction means and the gearbox within the conduit.
