TH8788C3 - Water turbine for tidal currents - Google Patents

Abstract

The DC60 (17/10/56) water turbine consists of two main parts: stationary parts, which include the support beams, rotor shaft, and buoys; and movable parts, which include the combination gear shaft, the combination gear set, the drive shaft, the pinion, the turbine blade drive gear, the shaft support bearings, the turbine shaft, the turbine blades, the upper rotor arm, the lower rotor arm, the hub support post, the upper hub, the lower hub, the pulley, and the rudder assembly. The rotor shaft acts as the pivot point and supports the entire rotor assembly by fitting onto the two hubs. The four pairs of rotor arms are connected by the upper and lower hubs, with the turbine blades supported by the rotor arms. The rotor shaft, which also serves as the sun gear shaft, is locked to prevent rotation. When the rotor rotates due to the water current, the combination gear also rotates, running on the sun gear which is locked to the rotor shaft. When the combination gear rotates, it transmits rotational force to the turbine blades via the power shaft. Therefore, the turbine blades are self-adjusting due to the rotor rotation. This self-angle adjustment of the blades is a unique feature that allows this invented water turbine to utilize both lift and drag forces to provide torque to the rotor, thus increasing its power efficiency. When the water flow changes direction, the rudder is turned in the opposite direction. Therefore, the rotational force from the rudder shaft is transmitted to the rotor shaft and then to the blade shaft. This allows the turbine blades to adjust their angle without changing the rotor's rotational direction. The water turbine consists of two main parts: stationary parts such as the support beams, rotor shaft, and buoy; and movable parts such as the combination gear shaft, the combination gear set, the power shaft, the pinion, the turbine blade drive gear, the shaft bearings, the turbine blade shaft, the turbine blades, the upper rotor arm, the lower rotor arm, the hub support post, the upper hub, the lower hub, the pulley, and the rudder assembly. The rotor shaft acts as a pivot point and supports the entire rotor assembly, fitting onto two hubs. The four pairs of rotor arms are connected by the upper and lower hubs, with the turbine blades supported by these rotor arms. The rotor shaft, which also serves as the sun gear shaft, is locked to prevent rotation. As the rotor rotates driven by the water current, the combination gear rotates on its own axis and runs on the sun gear, which is locked to the rotor shaft. This rotation transmits rotational force to the turbine blades via the power shaft. Therefore, the turbine blades are self-adjusting due to the rotor rotation. This self-adjusting capability of the turbine blades is a unique feature that allows this water turbine to utilize both lift and drag forces to provide torque to the rotor, thus increasing its power efficiency. When the water flow changes direction, the rudder is turned in the opposite direction, and the rotational force from the rudder shaft is transmitted to the rotor shaft and then to the blade shaft. This allows the turbine blades to adjust their angle without changing the rotor's rotational direction.
