摘要： A method and device for generating electricity from ocean waves. The device includes at least one magnetostrictive element and one or more electrically conductive coils or circuits. When the magnetostrictive element is deployed in a body of water, the motion of the body of water, including wave motion, causes changes in the strain of the magnetostrictive element. The electrically conductive coil or circuit is within the vicinity of the magnetostrictive element. A corresponding change in magnetic field around the magnetostrictive element generates an electric voltage and/or electric current in the electrically conductive coil or circuit.

摘要： A method for pumping liquid from an offshore natural gas production well (1) by means of a pump assembly (13, 14, 15) that is actuated by wave energy derived from waves in a body of water (11), such as an ocean, sea, lake or river surrounding an upper section (1A) of the well (1). The pump assembly (13,14,15) may comprise a first piston (14) near a lower end of a coiled water and/or other condensed liquid discharge conduit (10), which is actuated by second and third pistons that are arrange at the upper and lower ends of a hydraulic or pneumatic fluid conduit (20,21), wherein the third piston (22) is connected to a floating body (25), which is oscillated by waves (33), such that a pair of one way check valves (13,14) suck and push production water (H2O) and other condensed liquids sequentially from a lower region of the well (1B) into a lower portion (10B) and subsequently into an upper portion (10C) of the coiled water and other condensed liquid outlet conduit (10).

摘要： The invention is made up of a structure in which a floating piston is placed which slides up and down as a result of the movement of the sea and transmits the movement to inertia flywheels by means of the connecting rod, converted into rotating movement in gearboxes, which are connected to generators which transform the same into current.

摘要： A wave energy converter comprises a buoyant body (11) and an acceleration tube (14) dependent from and attached to the buoyant body (11) and having an upper end near the buoyant body and a lower end remote from the buoyant body. A section of the acceleration tube intermediate the upper and lower ends of the acceleration tube defines a working cylinder (16) and openings in the acceleration tube (14) above and below the working cylinder (16) allow substantially unobstructed water flow between the working cylinder and a body of water in which the acceleration tube is immersed. A working piston (17) is reciprocable in the working cylinder. An energy-absorbing device (18, 19, S) comprises paired resiliently extendable hose pumps (18, 19) operated by the working piston (17). One end of each hose pump within a pair is attached to the operating piston (17) on opposite sides thereof, and the other end is anchored to the unit which consists of the buoyant body (11) and the acceration tube (14).

摘要： Das Verfahren zur Wellenenergieumformung wird mit Hilfe einer Wellenenergieanlage durchgeführt, die ein Schwimmittel (1) enthält, in dessen Nähe vertikale Führungen (7) angeordnet sind, die die Wellenschwingungen minimal aufnahmen, wobei ein Schwingungserzeuger (2) mit Unwuchtmassen (3) vorhanden ist, die sich auf einer vorgegebenen Bahn mit Beschleunigung bewegen. Die Zusammenwirkung des Schwingungserzeugers (2) mit dem Schwimmittel (1) und den Führungen (7) geht solcherweise vonstatten, daß während einer jeden Periode des Hoch- und Niedersteigens des Schwimmittels (1) auf der Welle die Unwuchtmassen (3) sich mehr als einmal um ihre Achse (4) drehen, während die Drehachse (4) der Unwuchtmassen (3) sich unter Einwirkung und in der Einwirkungsrichtung des Schwimmittels (1) mehrmals verschiebt, wobei während einer jeden vollen Umdrehung der Unwuchtmassen (3) um die Achse (4) innerhalb vorgegebener Zeitintervalle mindestens eine Verschiebung der Drehachse (4) erfolgt, während bei jedem Wechsel der Perioden des Hoch- und Niedersteigens des Schwimmittels (1) auf der Welle die Bewegungsrichtung der Drehachse (4) der Unwuchtmassen (3) unter Aufrechterhaltung der in den Unwuchtmassen (3) aufgespeicherten Energie umgekehrt wird. Die Energieentnahme von den Unwuchtmassen (3) erfolgt während der Periode des Hoch- und Niedersteigens des Schwimmittels (1) auf der Welle.
Die Erfindung kann in der Energetik für die effektive Umwandlung der Wellenenergie in die elektrische Energie angewendet werden.

摘要： The present disclosure relates to an economical and ecological process for producing electrical energy. According to the disclosure, electrical energy is produced by conversion of wave energy. In illustrated embodiments, aquatic waves lift a floating body which, by use of a transmission system, linearly moves a magnet in the induction coil, or converts vertical motion of the floating body into circular motion of the generator which generates electricity. The energy generation system includes either flexible or inflexible transmission shafts which transmit the motion to rotary or linear generators. The present disclosure includes the system for producing electricity with fixed support to the bottom of the sea, and the system with lateral and central floating bodies, with rotating or linear generators coupled to transmission shafts positioned above the system for producing electricity.
