摘要： A wave energy absorption and conversion device and a power generation system includes a floating body, a guiding shaft, a damping plate and a counteracting mechanism placed in a movement range of the damping plate. The guiding shaft is connected to the bottom of the floating body and passes through the center of the damping plate. The damping plate may slide on the guiding shaft. A counterforce generated by the counteracting mechanism is opposite to a natural moving direction of the damping plate, so that the damping plate can be kept in a relatively static state under a synergistic effect of the counteracting mechanism, and thereby, colliding of damping plate with constraint structures above and below can be prevented when floating body is moving up and down following waves. The power generation system includes the wave energy absorption and conversion device and a power generation system.

摘要： An elastic couple barring apparatus (i.e., an elastic couple rotor turning gear) is a special tool to drive a rotor by elastic couple for adjusting a shafting center of a vertical hydroelectric generating set and other rotating devices. The elastic couple rotor turning gear is characterized in that an elastic support is mounted on a frame of the driven device, a casing being connected to the elastic support, a casing cover being firmly fixed on the casing, a speed reducer and an electric motor being installed on the cover, an output shaft of the speed reducer extending into the casing under the casing cover, the output shaft having a pinion gear mounted thereon and meshed with a gear body of a bull gear positioned in the casing, the bull gear being connected to a shaft coupling through parallel keys via a key seat or an upright post, and the shaft coupling being fixed on a rotor of the driven device. The advantages of the invention is that the structure is more reasonable, the concentricity may be adjusted more conveniently, the elastic connection makes operation easy and vibration small, deformation caused by suspending arms is eliminated, and operation's accuracy and precision are improved because the gears may be meshed and operated smoothly.

摘要： The invention is an Exit Stay Apparatus with Intermediate Flange for Francis and propeller hydraulic turbines. The purpose of the invention is to improve the effectiveness of known Exit Stay Apparatus (U.S. Pat. No. 6,918,744, July 2005, for Hydraulic Turbine and Exit Stay Apparatus therefor) in eliminating the axial central vortex and, therefore, in increasing the efficiency and decreasing the flow pressure pulsations in draft tube cone at off optimum operating regimes. The new Exit Stay Apparatus has an intermediate flange between exit stay crown and periphery and two sets of exit stay vanes: crown exit stay vanes secured to the exit stay crown and the intermediate flange and peripheral exit stay vanes secured to the intermediate flange and following to the periphery. When installed in the turbine the peripheral exit stay vanes are secured at the periphery. There are more crown exit stay vanes than the peripheral exit stay vanes and their profiles are longer than the profiles of the peripheral exit stay vanes. The Exit Stay Apparatus with Intermediate Flange is expected to have the same peak efficiency as known Exit Stay Apparatus.

摘要： The invention is an Exit Stay Apparatus for Francis and propeller hydraulic turbines. The purpose of the invention is to eliminate the loss of turbine efficiency and strong pulsations in draft tube caused by the axial circular vortex in all turbine operating regimes other than optimum without a noticeable decrease in maximum efficiency. It can be incorporated not only into newly fabricated hydraulic turbines, but also retrofitted into existing turbines. The Exit Stay Apparatus has a crown and exit stay vanes secured to the the crown. When installed in the turbine, the exit stay crown is located immediately after the runner crown, which is truncated at the bottom by a plane perpendicular to the central axis of the turbine. The exit stay crown together with the truncated runner crown forms water passages after the runner blade crown profile exit. The exit stay vanes are arranged in a circular array around the turbine axis, located after the runner blades, and attached at the periphery either to the draft tube cone or to an exit stay flange secured to the turbine discharge ring and to the draft tube cone.

摘要： A turbine installation having reduced inner and outer gaps comprises a water passageway and a turbine runner disposed in the passageway downstream of a discharge ring. The turbine runner includes a hollow hub having spaced apart inner and outer surfaces and a longitudinal axis and a plurality of runner blades. Each blade comprises a hydrofoil having an inner edge and a distal outer edge, a leading edge and a trailing edge separated by a water directing surface. Each blade is pivotally connected to the hub about a rotational axis extending in a direction generally perpendicular to the longitudinal axis so that its inner edge is proximate the hub. Each blade is rotatable between a maximum pitch position and a minimum pitch position. The discharge ring has a spherical configuration cooperable with the outer edge of each of the blades to reduce an outer gap formed between the outer edge of each of the blades and the passageway. The hub may be configured as a sphere downstream of the blade rotational axes to reduce an inner gap formed between the inner edge of each of the blades and the hub. The hub may also include a plurality of pockets or raised areas formed on the outer surface of the hub to reduce the inner gap formed between the inner edge of each of the blades and the hub.
