US9732724B1 – Reciprocating Fluid Energy Device – Google Patents

In yet another embodiment of the invention, the device 10 comprises a plurality of foils 100. See FIG. Movement to the left continues in the same manner as described above, with the foil first “flattening” and then “straightening up”, see FIGS. Commercial wind turbines have adapted to this relationship with large turbines using long contoured blades and high tips speeds (typically 6 to 7 times the wind speed) that remain efficient given sufficient wind speed. To efficiently transfer energy from a slow moving fluid, a large slow moving foil is needed. Because of the Bernoulli Effect, which provides that faster moving fluid exerts less pressure than slower moving fluid, the net pressure differential creates “lift” in the direction of the angle of attack, perpendicular to the direction of fluid flow. See FIG. 2I. The foil reverses in the same manner as described above, with first the leading edge of the foil reversing to the right and then the trailing edge of the foil reversing to the right.

Video Tip: Fusion 360 - Joints and Limits - YouTube It is therefore an objective of the present invention to provide a reciprocating fluid-energy device that can be used with any moving fluid. Hydro-power became a mature technology in the 1900s. Modern hydro-power has relied on high pressure/high head systems often associated with a dam or a reservoir. The machine to do useful work may be a pump or a grinding mill or some other such machine that directly receives the kinetic energy transferred by the force transfer mechanism 500. In the preferred embodiment it is a generator 700. In such embodiment the second end 514 of the force transfer mechanism 500 is in connection with the generator 700. The generator 700 is suitably configured to convert movement of the force transfer mechanism 500 into power.

Similarly, the second foil support member 900 has substantially the same size and shape as the first foil support member 800 and is oriented substantially perpendicular to the direction of fluid flow 20. It has a first end, a second end, a pair of downstream support connection points, and a plurality of foil connection points.

The device 10 may further comprise a force transfer mechanism 500. The force transfer mechanism 500 is any apparatus that is suitably configured to capture at least part of the motion of the device 10 created by the fluid flow 20, and transferring that motion to a machine to do useful work.

In yet another embodiment the frame 400 is configured to span a channeled body of water 40, such as a stream, and to be anchored on the banks 44 of the stream, with a portion of the frame 400 extending into the stream. Because the upstream end of the upstream support member is pivotally connected to the frame of the device at a fixed location, the upstream support member pivots to the left and right as the foil moves laterally, with the end of the upstream support member connected to the leading edge of the foil tracing an arc 72. Similarly, the downstream support member pivots to the left and right from its connection point with the frame as the foil moves laterally, with its end connected to the trailing edge of the foil also tracing an arc 74. Dolor de espalda remedios naturales . The two arcs 72,74 traced by the upstream and downstream support members are mirror images of each other, and are closest to each other at the midpoint of the lateral traverse of the foil.

The upstream support member and the downstream support member have a fixed length, as does the foil. The combined lengths of the upstream support member, the downstream support member, and the foil is greater than the distance along the device axis from the upstream portion of the frame to the downstream portion of the frame. FIG. 5 is a top plan view of an embodiment of the invention wherein the foil is a boat and the upstream support member is a chain.
