Curso de Acupuntura - Iniciación. Cursos Delena Formación A sway vibrating body (bowstring member) (not shown) of the third embodiment is different from the sway vibrating body (bowstring member) 1 described in the first embodiment in that the sway vibrating body (not shown) of the third embodiment is placed in a manner to have an arched shape in advance, even without acting of the fluid force in a water current. In addition, since the arched shape of the sway vibrating body has a structure on which a fluid force can be effectively exerted even from a tidal current flowing an upward or downward slanting direction, the water current power generating device according to the third embodiment can be more preferably used in a water current area flowing an upward or downward slanting direction. The water current power generating device (not shown) according to the third embodiment includes an arched shape of a sway vibrating body which bends further in response to a fluid force exerted by a water current, and sways in a bending state, and generates tension in response to a deflection angle from the current direction, and a pair of tension power generating units for converting electromagnetically or piezoelectrically the tension transmitted from the sway vibrating body into electric power.

Even in the third exemplary embodiment, the same effect as obtained in the first embodiment can be realized. SUMMARY OF THE INVENTION In view of the above, it is a first object of the present invention to provide a water current power generating device capable of generating electric power efficiently from water current power variety of water areas of slow-moving water current to fast-moving water current, despite its compact and lightweight, simple and inexpensive configuration. Therefore, despite the simple configuration of the sway vibrating body 1, the sway vibration power generating device can be effectively used in a variety of water areas of slow-moving water current to fast-moving water current.

In addition, since the sway vibrating body is made up of a bowstring member or an arched shape of a tension generating member, its compact and lightweight, simple and inexpensive configuration can be achieved. In addition, the bowstring member is not limited to a cord of solid wire and may be a twisted code, such as a rope, made of a plurality of element wires twisted together, since the bowstring member is not susceptible to adhesion of marine life. In addition, the tape shape of tension generating member may be configured to have a widest part in the central portion, in order to achieve still greater tension. As the buoy moves up and down in response to passing waves, the propeller is moved up and down through the relatively still waters below the surface. 1 bends in response to a fluid force exerted on a circumference surface thereof by a water current, and sways in a bending state within a maximum deflection angle “α” (maximum variation) from the direction of water current.

The maximum tension generated in the sway vibrating body 1 acts as maximum pressure on the piezoelectric elements 5, 5 through the tension transmitting plate 6, 6, whereby output voltage from each tension power generating unit 2, 2 also reaches its maximum ((c) in FIG. On the other hand, in the sway variation power generating devices according to the present invention, even if a plurality of sway vibrating bodies is arranged adjacent to each other, the interference of the sway vibrating bodies does occurred unless the sway vibrating bodies do not contact each other.

At a time of away motion, the sway vibrating body (bowstring member) 1, both end portions of which each are secured or engaged to the outer face of the tension transmitting plate 6 by using the fixture 8, bends in an arced shape and sways in a tense state in a downstream direction.

The bowstring member described in the first embodiment is in particular suitable for uses in a tidal current or an ocean current that shifts direction at frequent intervals, whereas the tape shape of tension generating member used in the second embodiment is in particular suitable for uses in a tidal current or an ocean current that does not shift direction at frequent intervals. Furthermore, there is a problem that the Karman vortex power generating device also is not suitable for uses in a tidal current or an ocean current shifting direction at frequent intervals, since power generating efficiency varies and reduces depending upon the direction of water current, as in the case with the axial flow water wheel power generating device. As materials for the above-mentioned bowstring member making up the sway vibrating body 1, a metal, a synthetic resin material, and a metal/resin composite all may be preferably used, as long as their materials have high tensile strength, flexibility, and is resistant to plastic deformation.

However, instead of the case, tensile stress may be applied. Therefore, with configurations of the present embodiment, an appropriate current velocity range can be widely adjusted arbitrarily, within a range of elastic limit of the sway vibrating body 1, without requiring any complex mechanism by which tension for adjustment is applied to the sway vibrating body 1, and any mechanism for supporting the sway vibrating body 1 in a manner of elastic suspension. It will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the sprit and scope of the present invention as defined by the claims. Faja para dolor lumbar . Without this central rigid support, the orientation of the venturi shroud would be unstable, i.e., under the influence of water moving past it as it rises, the shroud would tend to turn sideways and a collapsible shroud would tend to partially collapse.

Moreover, with the fluttering vibration power generating device, there is also a problem that, when a plurality of the fluttering vibration power generating devices is located in close proximity, mutual influence between the fluttering vibration power generating devices cannot be ignored. Consequently, there is a problem that, for the Karman vortex power generating device to increase efficiency of power generation, a column body having a great diameter can be effectively used in fast-moving current area, but not in a slow-moving current area, whereas a column body having a small diameter can be effectively used in a slow-moving current area, but not in a fast-moving current area. For example, a mode of vibration is not limited to a thickness vibration and, if necessary, may be thickness-shear vibration, a flexural vibration or any other mode of vibration. This invention relates, generally, to wave energy conversion devices that convert abundant natural energy present in oceans and other bodies of water into electrical or chemical energy such as the creation of hydrogen from water through electrolysis.

FIG. 3 is a group of wave form charts showing a vibration angular variation and a tension variation of the sway vibrating body making up the water current power generating device as shown in FIG. However nevertheless, the galloping vibration power generating device described in patent references 4 has disadvantages of increasing in structural complexity and manufacturing cost. Moreover, the above-mentioned piezoelectric element may be of either one of an integral configuration and a laminated configuration. Moreover, the water current power generating device utilizing the fluttering vibration (hereinafter, may be referred to as fluttering vibration power generating device) is disclosed, as a wind/water power generating device, in non-patent reference 1 (M. Yamagishi et al.; “Study on the fluttering characteristics of multi-articulated flat plate in the mean-flow”, Proceedings of the 43rd and 44th JAXA Workshops on “Investigation and Control of Boundary-Layer Transition”; Japan Aerospace Exploration Agency, pp. It is not required to adjust compulsorily a resonance frequency of the sway vibrating body 1 to be within a specified frequency range, since the sway vibration power generating device does not utilize Karman vortices.

Thus, the sway vibrating body (bowstring member) 1 is placed between the opposed tension power generating units 2, 2 (piezoelectric elements 5, 5) in a manner to be able to sway in a bending and tensioned state, when put in a water current. When the sway vibrating body 1 vibrates in a mode of sway, as shown in FIG. When the lateral vibration displacement “β” reaches its maximum (“B” in FIG. 4, a lateral vibration displacement “β” which occurs on the column body by the Kaman vortices reaches its maximum (“B” in FIG. 2), the tension “σ” generated in the sway vibrating body 1 reaches its maximum ((b) in FIG. That is, once the sway vibrating body 1 has varied at a certain deflection angle from the direction of water current, the sway vibration thereof is continued as self-sustained vibration by kinetic energy generated based on inertia force arising from mass and the elastic force arising from tension.

The sway variation moving around from side to side is generated even in slow-moving water current, since the sway vibrating body 1 has low rigidity. Here, FIG. 2, shows exaggeratedly for emphasis a state in which the sway vibrating body 1 bends in the arc shape. 41-44, February 2010), for example. Consequently, a force is constantly exerted on a circumference surface of the sway vibrating body 1 by a water current from an approximately normal direction to any portion of the circumference surface thereof. The continuity equation states that the fluid “mass flow rate”-the amount of fluid traveling through a tube per unit time-must be the same at any cross section of the tube or else there is an accumulation of mass-“mass creation”-and the steady flow assumption is violated.
