    摘要： An apparatus and method for extracting energy from an oscillating working fluid, such as ocean waves includes an apparatus (10) having an internal flow passage (40) for the working fluid, a turbine (44) and a flow control device (38), each of the turbine (44) and the flow control device (38) being in direct fluid communication with the flow passage (40), where the flow control device is selectively moveable between a first configuration in which the flow control device is open to allow a flow of the working fluid, such as air, to exit the flow passage therethrough, and a second configuration in which the flow control device restricts a flow of the working fluid therethrough, the working fluid then entering the flow passage via the turbine, which can be harnessed to generate electricity.

    摘要： The present invention relates to an air turbine capable of without change in its rotational velocity direction, efficiently absorbing the energy associated with a pressure difference between two spaces (A) and (B) of successively changing sign, as in the case of sea wave energy systems. The turbine comprises two sets of blades (I) and (II), each of which is similar to the blade system of a conventional turbine of radial-, mixed- or axial-flow type. The turbine also comprises a system of ducts that connect spaces (A) and (B) through any of the two blade sets (I) and (II). The turbine may be equipped with a fast-acting valve that stops the flow through one or both blade sets (I) and (II).

    摘要： A turbine structure, includes a rotor having a hub rotatable about a central axis of rotation and adapted to be operatively coupled to an external system generating electric power, a plurality of laminar elements firmly associated with the hub and arranged peripherally of the central axis of rotation to intercept a fluid stream, wherein each laminar element includes a flexible seal having upper and lower opposite faces adapted to alternatively engage the fluid stream to deform and transmit a driving torque to the rotor. The seals radially extend outwardly from the outer peripheral wall of the hub with respective opposite faces extending, in a non-deformed condition, mainly in planes substantially coplanar with each other and to the plane of the hub, perpendicular to the axis of rotation, to define as a whole respective mutually opposite surfaces adapted to be alternately invested by the fluid stream on their entire extension.

    摘要： Provided is a floating water wave energy collection and conversion system, which comprises at least two buoyant members (101, 102) floating on the surface of the water and connected movably with each other in series, wherein the movable connection can be a hinged connection. A power transmission device and an energy conversion device (103) are provided on the buoyant members and the power transmission device and the energy conversion device (103) of adjacent buoyant members (101, 102) are movably connected with each other, being able to make a relative movement with respect to each other. As water waves fluctuate, two adjacent buoyant members (101, 102) rotate relatively, with an axis of a hinge shaft as the centre line, so as to drive the power transmission device and the energy conversion device (103) on the buoyant members to make a relative movement, thereby achieving energy conversion. The energy conversion device is a line type generator, a rotary generator driven by a rack and pinion, a hydraulic oil cylinder, a pneumatic cylinder or a hydraulic cylinder. The conversion system can utilize water wave energy effectively, has a simple structure and is low cost, thereby facilitating implementation and application.

    摘要： An energy conversion system is provided including an annular member disposed around a shaft and at least partially defining a first radial flow passage that is fluidly coupled to a wave chamber and a second radial flow passage that is fluidly coupled to a port. A first plurality of nozzle vanes may extend at least partially through the first radial flow passage and may be configured to impart a first exit swirl angle in a fluid. A second plurality of nozzle vanes may extend at least partially through the second radial flow passage and may be configured to impart a second exit swirl angle in the fluid. A turbine wheel may be coupled to the shaft and disposed radially between the shaft and the annular member. The turbine wheel may define an axial flow passage fluidly coupled to the first and second radial flow passages and may include impulse blades.
