SUBMERSIBLE ELECTRICAL WICKET GATES OPERATOR

摘要

A system and method for electrically controlling a submersible hydro-electric production system for avoiding leakage of oil and contaminants used in the existing hydraulic systems. The system comprises one or more submersible electrical actuators operably connected to a gate operating ring which in turn is connected to a plurality of wicket gates in the turbine. Each submersible electrical actuator comprises an electrical motor connected to a push-pull rod which is configured to transform the rotation movement received at a first end thereof to a linear movement at a telescoping end opposite the first end for rotating the gate operating ring to a desired position. The electrical actuator includes a waterproof structure which houses the electrical motor and the push-pull rod and at the same time allows for a telescoping movement of the push-pull rod for rotating the gate operating ring.

1. A submersible hydro-electric production system comprising:
a turbine comprising a plurality of wicket gates configured to open and dose to control a flow of water through the turbine; a wicket gate operating ring operably connected to the plurality of wicket gates for rotating the wicket gates between an open position and a closed position; one or more electrical actuators operably connected to the wicket gate operating ring and configured to rotate the gate operating ring to a desired position in response to a control signal; each electrical actuator comprising an electrical motor and a push-pull rod operably connected to the electrical motor for transforming a rotation movement of the electrical motor to a linear movement for rotating the gate operating ring to the desired position.
