Hydrodynamic pump installation

A tubular pile anchored in the river bed has a double-acting pump made of worn-out car tyres attached to it by means of frame clamps. The pump is driven via a loop of rope by a drive sleeve which is mounted between the frame clamps. Fastened to the journals of the drive sleeve there is a drive fork to which a long drive lever is linked. At its end, one or more drive rudders are mounted which are steered independently. The drive rudder is immersed in the river flow in a floating manner and is laterally deflected thereby owing to the oblique incidence. The angle of attack is determined by a limiting chain fastened to the drive lever. Owing to the drive lever swinging back and forth, wide flows can be utilised. A plurality of such installations can be combined into an installation working in parallel. In such an arrangement, the ends of the drive levers are linked to one another by means of a transverse beam. Many drive rudders can be mounted on the transverse beam, which makes it possible ...

Strömungskörper

Flexible, wechselseitig von Wind oder von Wasser angeströmte Flügel

Bekannte Flügel bestehen aus starren Materialien und Formen, so dass sie sich den unterschiedlich auf sie einwirkenden Strömungskräften aus Luft oder Wasser nicht anpassen können. Hierdurch bleibt ein Teil der Strömungsenergien ungenutzt. Durch ihre Unnachgiebigkeit werden sie zudem stark belastet, was massive Flügel-Strukturen erforderlich macht. Diese führen zu höheren Gewichten, die das Reaktionsvermögen der Flügel zusätzlich mindern. Dadurch kann die Strömungsenergie, insbesondere die von starken, in der Richtung wechselnden Strömungen von den Flügeln nur teilweise in Bewegungsenergie umgewandelt werden, der Rest wird als Belastungsenergie aufgenommen. Höhere Flügel-Gewichte führen durch höhere Fliehkräfte zu höheren Flügel-Belastungen. Diese wirken sich bei Flügeln von Rotoren mit vertikaler Achse besonders stark aus und führen zudem zu stark verschlechterten Rundläufen. Aus statischen Gründen müssen mit zunehmenden Flügel-Gewichten auch die Querschnitte ihrer Flügel und Rotor-Naben ...

Transforming the energy of fluid flow, eg wind or river flow, into another form of energy

The kinetic energy of fluid flow, eg wind or river flow, is transformed into another form of energy, eg electrical, heat or mechanical, by flowing the fluid medium through a duct 1 and over a working surface of a working element 2 of an energy converter 28 so that the flow induces oscillations of the working element 2. The working element 2 may form a moving rectangular vane hinged at its downstream end and forming a partition separating the flow into two channels. The duct may have an inlet 10 in the form of a nozzle and an outlet 12 in the form of a diffuser. The vane 2 may be connected mechanically, eg via crank (50, fig.6), to the energy converter, eg dynamo (28, fig.5) or a pump. One or more turbines 200 may be located downstream of the vane 2; oscillation of the vane causes pulsations which actuate the turbine(s) more effectively than would a steady flow.

Wind/water turbine with rotational resistance reduced by wind vane blade

A vertical axis type wind/water turbine mainly consists of rotationally symmetric vanes which are secured at both ends thereof to supporting plates, the vane being made up of several blades, the blade having one vertical side being attached to a blade rotating shaft, the other free side being individually allowed to rotate freely in the shape of a sector between both the adjacent blade rotating shafts. When the vane of the wind/water turbine is convex against a wind/water flow, the blades are pushed and opened by the wind/water flow to reduce rotational resistance. When the vane is further rotated to be concave, the blades block between the blade rotating shafts and allow the entire face of the vane to be subjected to a wind/water pressure, providing a high rotational force with the rotational resistance reduced. To avoid risk, the foot of all the blades can be only wound around or retreated to the blade rotating shaft to make the horizontal sides of the blade shorter than the interval ...

System and method for generating electrical power from a flowing current of fluid

A helical turbine is operatively connected to at least one generator system for generating electrical power. System performance is optimized by controlling the operative angle between the longitudinal axis of the turbine and the direction of the current flow and by controlling a pitch ratio of the turbine. A pair of turbines, arranged in V-shape, each at the operative angle from a neutral centerline, provides symmetry and counteracts reactive torque. For wind operations, the V- shape is freely rotatable into the wind. For bi-directional tidal operations, the V- shape is part of a buoyant structure, positioned in the current and anchored to the floor. The structure is fit with control surfaces to ensure the system orientation. In unidirectional currents, one or more turbines can be angled downwardly into the current at the operative angle, elevators ensuring the angle is maintained.
