Undercurrent electric generator system

Номер: US20120153629A1
Автор: Baudilio Sanchez Sanchez
Принадлежит: Individual

This invention discloses the efficient, non-polluting generation of electricity through the construction and use of an electric power generating system wherein electricity is generated by utilizing the powerful subsurface undercurrents present near an ocean shoreline. The undercurrent water is caused to cycle internally through a conical shell housing assembly constructed in an upwardly narrowing configuration to produce a nozzle effect within the shell housing. The nozzle effect generates a combined water and air power piston that alternates in a vertical direction within the shell assembly. In both the upward and downward cycles, the power piston impacts a fan blade component that causes the shaft of an electricity generating turbine to rotate and produce electricity.

The present invention refers to a underwater unit ( 1 ) for a hydroelectric power plant and a modular hydroelectric power plant ( 2 ) comprising a plurality of such units. The unit ( 1 ) according to the invention uses the principle of functioning of the traditional hydroelectric power plants and comprises a penstock ( 200 ) which involves a “head” of at least 100 m, and preferably of about 150-300 m, and carries elevated kinetic energy water masses from the surface of a water basin down to one or more turbines ( 301 a - 301 f ) provided in depth under the surface of the basin itself, so as to transfer the kinetic energy from the water to said turbines and to transform then the kinetic energy into electric power. Thanks to the use of variable volume discharge tanks ( 313 a , 313 b ) positioned downstream the turbines, it is possible to easily and effectively return the water masses used for the actuation of turbines themselves to the surrounding environment.

A marine hydrokinetic electric power generator comprises one of a stator and a rotor which is adjustably movable through an infinite number of positions from being proximate to one another so that their magnetic fields overlap mostly to a position such that the rotor is most distant from the stator and has little overlap of magnetic field strength. Hatch and speed control may be also provided by a spur/helical gear assembly of sun and planetary gear sets referred to herein as a Transgear™ gear assembly. The variable (or fixed) power generator in operation may comprise one of a rotor and a stator being out of phase with one another by an angle, for example, the one of the rotor or the stator leading or lagging the other. In this instance, a motor such as a servo motor may be used to rotationally compensate for the out-of-phase angle by radially moving the rotor with respect to the stator or vice versa. The variable (or fixed) power generator may also be applied in a cam-controlled speed converter and a wind turbine electric power generator. The variable power generator of a marine hydrokinetic electric power generator may be used as a low torque generator and a high power-rated generator in these applications and may generate more electric power than a conventional fixed power generator (the rotor axially aligned to overlap the stator in a conventional manner). 1.

The APPARATUSES, METHODS AND SYSTEMS FOR HARNESSING FLUID FLOW WITH FLEXIBLE MECHANICAL TRANSDUCERS include mechanisms that include flexible elements with strained deformations. In some implementations, oscillations of strained deformations in fins are excited by a moving fluid. By coupling the fin structure to an electrical generator and/or pump, energy from the moving fluid can be converted into electrical energy or used to perform useful mechanical work. In some implementations, the fin may be coupled to a motor or other actuator which causes the strained deformations to move, thereby imparting force onto the fluid to move or mix fluid or perform other useful work.
