  • Publication number: 20220145774
    Abstract: A hydraulic lock apparatus includes a hydraulic actuator, a pressure storage device connected to the hydraulic actuator, and a control valve configured to actuate to a first position and a second position. The control valve fluidly isolates the pressure storage device from the hydraulic actuator when the control valve is in the first position. The control valve fluidly connects the pressure storage device to the hydraulic actuator when the control valve is in the second position.

  • Patent number: 8581430
    Abstract: A hydroelectric turbine generator and control system is provided that optimizes the maximum possible power output at all times by strictly monitoring power output from the generator unit and modulating the wicket gate angle and the runner blade pitch independently of one another. The hydroelectric turbine generator includes a means for separately controlling wicket gate angle and runner blade pitch. The wicket gate angle control mechanism controls the flow into the system, pre conditions flow for maximum power and maintains reservoir level. The runner blade pitch control mechanism continuously monitors the system power output based on actual power produced, and adjusts system parameters in order to achieve maximum power output.

  • Patent number: 7579703
    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.
