Wave-powered motor

Wave Powered Motor Abstract A dome-shaped atoll structure (12) having a central aperture at its apex is secured to a station-keeping structure (11, or 40, or 52) posi-tioned on the ocean bottom. The atoll structure (12) is moveable through a range of vertical positions relative to the ocean bottom. Sea waves impinging on the atoll structure (12) are refracted as they crest and break, thereby producing spiralling pulses of water that converge toward the central aperture. The central aperture provides entry into a vertical standpipe (14) for the pulses of water, which impart angular momentum to water already present in the standpipe (14). A turbine (31) attached to a shaft (26) in the standpipe (14) to rotational energy of the shaft (25), which is coupled to an electrical generator (27). The elec-tric power output of the generator (27) is measured for various vertical positions through which the atoll member (12) is moved, so that a posi-tion of optimum power output can be determined for any given combination of see state and/or tidal conditions.

"wave energy converter"

A method and apparatus of harnessing wave energy is described. A wave energy harnessing reservoir has an inlet side and an outlet side, the inlet side being arranged to open or close and the outlet side including a tunnel in which a turbine is located. The reservoir extends from close to the seabed to well above the mean sea level, enabling it to capture nearly the entire energy flux of an ocean wave. When a wave enters the reservoir the inlet side closes, resulting in the formation of a raised water level within the reservoir.

Wave-energized diode pump

Disclosed is an apparatus that floats at the surface of a body of water over which waves pass. Passing waves cause a nominally vertical axis of the apparatus to tilt away from an axis normal to the resting surface of the body of water. Tilting of sufficient magnitude and duration allows a fluid to flow through a channel. Flowing water is trapped at a plurality of levels which in an un-tilted apparatus are higher than the respective levels from which the fluid has flowed. A subsequent tilt of the apparatus in a sufficiently different direction, and of a sufficient magnitude and duration, causes the trapped water to flow to new, yet higher levels. Successive wave-driven tilts of the apparatus incrementally raise water to a height and/or head from which a portion of its gravitational potential energy can be released, and/or converted to electrical power.

The tube partially encloses a substantial volume of water with which the tube's constriction interacts, creating and/or amplifying oscillations therein in response to wave action. Wave-driven oscillations result in periodic upward ejections of portions of the water inside the tube that can be collected in a reservoir that is at least partially positioned above the mean water level of the body of water, or pressurized by compressed air or gas, or both. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power (making the device a wave engine), or else the device's pumping action can be used for other purposes such as water circulation, propulsion, or cloud seeding.

An installation for using sea movements to generate electricity

677,186. Utilizing wave energy. GARCIA, R. D. April 20, 1950 [Oct. 18, 1949], No. 9714/50. Class 69 (i). An installation for using sea movements to generate electricity comprises a sea wall 1 with a surface 14 sloping upwardly from sea level to an inclined conduit 5 which is carried by a float 4 and which discharges the collected water downwardly through conduits 16 to turbines 15 coupled to generators. As shown, the wall 1 comprises an open-ended channel made of reinforced concrete resting on the sea bed and having hollow sides 2 open to the sea through perforations 3. The surface 14 is pivoted to the conduit 5 and slidably rests on the inclined outer surface of the outer side 2. The wall 1 carries transverse bracing beams 11 which interconnect bracing ties 10 and guide rods 13. Screw-threaded shanks 12 fixed to the float 4 are guided by collars in the beams 11, whilst the conduit 5 is carried by beams 6 slidably engaging the guide rods 13, to which they may be locked, and adjustably mounted on the shanks 12 by means of motors 9 and gearing 7, 8. The conduits 16 are telescopically mounted, whilst the turbines 15 and the generators are mounted on an independent float.

WAVE ENERGY EXTRACTION MACHINE

Machine d'extraction de l'énergie des vagues. Elle comprend un réservoir haut et un réservoir bas qui sont équipés de clapets de retenue. Lorsque la crête d'une vague atteint le réservoir haut, ses clapets s'ouvrent de façon à permettre à l'eau d'y pénétrer, puis ils se referment pour empêcher l'eau d'en sortir. Lorsque le creux de la vague atteint le réservoir bas, ses clapets s'ouvrent de façon que l'eau qu'il contient puisse sortir, mais il se referme pour empêcher l'eau de refluer. Entre les réservoirs hauts et bas, l'eau s'écoule par une turbine à axe vertical qui en extrait ainsi l'énergie. Application à l'extraction de l'énergie des vagues de la mer. Wave energy extraction machine. It consists of a high tank and a low tank which are fitted with check valves. When the crest of a wave hits the high reservoir, its valves open to allow water to enter, then close again to prevent water from escaping. When the bottom of the wave hits the low tank, its valves open so that the water in it can come out, but it closes again to prevent the water from flowing back. Between the high and low reservoirs, the water flows through a vertical axis turbine which thus extracts energy. Application to the extraction of energy from sea waves.

Apparatus for increasing the velocity of water flow for electric power generation and other uses

File No. 1426 P/2 CA ABSTRACT OF THE DISCLOSURE Apparatus for increasing the velocity of water or liquids containing water, comprising structural means interposed in the path of water flow or moving relative to the water. The structural means includes at least one side wall which is longitudinally curved from a diverting point at the outer end thereof to a gradually flattened curve at the inner end thereof. The wall is transversely curved from a generally planar surface at the outer end thereof to a curvature approaching circular at the inner end thereof. The velocity of the water or liquid is thereby substantially increased. Such velocity enhancement can be utilized for the gener-ation of electrical energy or for collecting and separating oil or other pollutants from water. In this latter use, a vessel is propelled through the water, and the increased velocity permits the water-pollutant mixture to be delivered to separating equipment without pumping assistance.

El dispositivo tiene una cámara de compresión de aire y una disposición de válvulas, operables para abrirse y cerrarse para regular el flujo del fluido a través de las aberturas de válvula asociadas. Las válvulas son operables para cerrarse progresivamente a medida que el flujo de fluido es incidente en las mismas, enfocando de esta manera el flujo del líquido hacia la cámara de compresión de aire y comprimiendo el aire en la misma. Las válvulas también se abren en un flujo de retorno de líquido de la cámara de compresión.

Una inclinación subsecuente del aparato en una dirección suficientemente diferente hace que el agua atrapada fluya a niveles nuevos.

A subsequent tilt of the apparatus in a sufficiently different direction causes the trapped water to flow to new levels.
