WO2016044325A1 – Optimized Heave Plate For Wave Energy Converter – Google Patents

Fisioterapia Deportiva - Logroños Fisioterapia Some embodiments comprise a device for generating electricity, wherein the device comprises: a buoy deployed in a body of water; a magnetostrictive element mechanically coupled to at least one buoy and at least one heave plate, wherein the motion of the body of water, including wave motion, causes motion of the buoy, which in turn causes changes in the strain of the magnetostrictive element; and an electrically conductive coil or circuit within the vicinity of the magnetostrictive element, wherein a corresponding change in magnetic flux density in the magnetostrictive element generates an electric voltage and/or electric current in the electrically conductive coil or circuit, wherein there is no substantial relative motion between the one or more magnetostrictive elements and the one or more electrically conductive coils or circuits. In one embodiment, the method for converting wave energy includes utilizing the motion of a body of water to apply hydrodynamic forces on a surface float and a heave plate, resulting in forces being applied to at least one generator mounted within the surface float resulting in electric power production by the generator.

Mi dolor.. Embodiments of a method for converting wave energy are described. Application No. 13/541,250, filed on July 3, 2012, and entitled “Apparatus for Harvesting Electrical Power from Mechanical Energy,” which is incorporated herein in its entirety. Fig. 6 depicts one embodiment of a resulting RAO, with the top plot showing overall power response against frequency and the bottom plot showing heave and pitch power response. However, by establishing the mass properties of the heave plate and surface float accordingly, the wave induced pitch motion may be used to generate significant alternating forces in the tethers. In some embodiments, the heave plate may have moment of inertia in at least one mode of motion that is over 2 times that of at least one surface float. Some embodiments are related to a wave energy converter system where the heave plate has a moment of inertia in at least one mode of motion (e.g.

In other embodiments, the heave plate may have moment of inertia in at least one mode of motion that is over 5 times that of at least one surface float. Some embodiments of the present invention comprise a device for generating electricity, the device comprising: at least one magnetostrictive element, at least one buoyant device (or buoy), at least one heave plate and when deployed in a body of water, the interaction of waves with at least one buoy causes changes in the strain of one or more magnetostrictive elements; and one or more electrically conductive coils or circuits within the vicinity of one or more of the magnetostrictive elements, wherein a corresponding change in magnetic flux density in the one or more magnetostrictive elements generates an electric voltage and/or electric current in the one or more electrically conductive coils or circuits, wherein there is no substantial relative motion between the one or more magnetostrictive elements and the one or more electrically conductive coils or circuits.

Mujer teniendo dolor en el hombro - Foto Premium Some embodiments comprise utilizing the motion of the body of water, including the wave motion, comprises utilizing motion of one or more buoys, which in turn causes changes in the strain of one or more magnetostrictive elements to which one or more buoys and/or heave plates may be coupled mechanically; and using a corresponding change in magnetic flux density in the magnetostrictive elements to generate an electric voltage and/or electric current in one or more electrically conductive coils or circuits that are in the vicinity of the magnetostrictive elements. Heave plates can be used in wave energy converters (WECs) to provide what is essentially an inertial reference for the device other than the ocean floor. This additional freedom of motion limits the heave forces that can be generated when compared to a fixed reference. This configuration might look similar to that depicted in Figure 2. In this figure, the plate entraps a significantly larger volume of water when the buoy 106 is pulling it towards the surface (the added mass of the displaced water with the plate is very large), but the plate 202 can move more easily downward as the tension is decreased (the added mass of the displaced water with the plate is relatively small in the downward direction).

Fig. Dolor de planta de pie derecho . 1 depicts an embodiment of a device 100 for generating electricity for use with a heave plate 102. In one embodiment, the heave plate 102 is a simple plate with taut tether(s) 104 extending upwards that connect to a surface float 106, floating in water 108. The plate 102 may be either a solid surface, or may contain perforations 112 or be perforated such that water 108 can flow through it, albeit it in a restricted manner. As an alternative, the geometry of the heave plate can be varied to provide increased hydrodynamic mass properties in an asymmetric form that would allow a physically lighter structure to provide the same reaction forces as compared to a much heavier symmetrical structure. In one embodiment, the perforations 1 12 that are mentioned in the description of the symmetric plate 102 could also be tailored to be asymmetric 202, such that the perforations 112 themselves restrict the flow of water 108 in one direction more than the other.
