System for converting tidal wave energy into electric energy

摘要

A system for converting marine surface wave energy into electric energy includes a barrier disposed generally vertically and having at least a portion thereof disposed above a surface of a body of water. The portion has a substantially planar surface disposed generally transverse to direction of marine surface waves. Bottom edge of the barrier is pivotally connected to one of a floor bed, a rigid formation and a rigid structure. At least one linear electric generator is coupled to storage of electric energy and is operable by a pivotal movement of the barrier. One type of electric generator is disposed external to the barrier while another type is mounted within a barrier chamber.

主权项

1. An electric generator comprising:
(a) an elongated housing having each of a tubular cross section in a plane transverse to a length thereof, a closed front end and an axially opposed closed rear end; (b) a center aperture formed through a thickness of the front end; (c) at least one annular coil stack mounted within a hollow interior of said housing mediate ends thereof; (d) a shaft centrally disposed within said housing; (e) a plurality of annular permanent magnets secured in series on an outer surface of said shaft; (f) a plurality of annular spacers secured on said outer surface of said shaft and interposed with said plurality of annular permanent magnets; (g) an annular gap formed between an inner peripheral surface of said coil stack and an outer peripheral surface of said magnets and said spacers; (h) a sliding bearing mounted at each end of said shaft; (i) a centering block mounted at said each of said shaft adjacent to a respective sliding bearing; (j) a resilient bumper mounted on each end of said shaft; (k) a seal mounted internal to said housing adjacent said front end thereof; (l) a drive rod having a proximal end thereof secured to a front end of said shaft, said drive rod extending outwardly from outer surface of said front end through said center aperture; (m) an annular flange secured to said drive rod adjacent to a distal end thereof; (n) bellows having one end thereof secured to said annular flange and having an opposed end thereof secured to said front end of said housing; (o) a coiled attenuating compression spring caged within said bellows between said closed front end of said housing and said annular flange; and (p) a pivot mounted at said distal end of said drive rod.
