Abstract:
1. Wave energy collecting device comprising an array of buoyant members ( 4 ), each buoyant member ( 4 ) being provided with an upper planar basement ( 26 ) and a lower planar basement ( 27 ), structural members interconnecting said array of buoyant members ( 4 ), a pipe network ( 15 ) being lined along said structural members, a working fluid medium flowing within said pipe network ( 15 ), a plurality of pumps ( 7 , 14 a , 14 b , 17 ) being employed to impart wave induced pressure pulses in said working fluid medium and appropriate machinery ( 21 ) receiving an input of said working fluid medium and providing an output of appropriately exploitable energy, characterised in that a repeatable module ( 1 ) of said wave energy collecting device comprises three pairs of buoyant members ( 4 ), a tubular shaft connecting means ( 5 ) being employed to interconnect each pair of buoyant members ( 4 ), said three pairs of buoyant members ( 4 ) being arranged in a circular configuration, a trilateral radial plank member ( 3 ) comprising three identical equidistantly spaced members being located centrally within said circular configuration of said three pairs of buoyant members ( 4 ), each one of said three identical members of said trilateral radial plank member ( 3 ) extending perpendicularly across each said tubular shaft connecting means ( 5 ) in between a pair of buoyant members ( 4 ), each said tubular shaft connecting means ( 5 ) being provided with a medially upwardly extending rectangularly shaped member ( 6 ), an upper side of said rectangularly shaped member ( 6 ) constituting a shaft means ( 6 a ), said shaft means ( 6 a ) of each said tubular shaft connecting means ( 5 ) being pivotally hinged to one of said three identical equidistantly spaced members of said trilateral radial plank member ( 3 ), each member of said trilateral radial plank member ( 3 ) of said module ( 1 ) being linearly connected to a member of the trilateral radial plank member ( 3 ) of an adjacent module ( 1 ) through an elastically loaded spring assembly ( 8 ), a first array of upwardly inclined pumps ( 7 ) being mounted onto said upper planar basement ( 26 ) of each buoyant member ( 4 ) perimetrically around a centrally located cavity ( 31 ) and onto a vertically upright extending member of the tubular shaft connecting means ( 5 ), said first array of pumps ( 7 ) imparting a first pressure pulse in said working fluid medium in response to wave induced movement of said buoyant member ( 4 ), a second array of pumps ( 17 ) being located adjacently each said shaft means ( 6 a ) pivotally hinged to one member of said trilateral radial plank member ( 3 ), said second array of pumps ( 17 ) imparting a second pressure pulse in said working fluid medium in response to wave induced rotation of said tubular shaft connecting means ( 5 ) around said shaft means ( 6 a ), and a third array of pumps ( 14 a , 14 b ) being located adjacently each said spring assembly ( 8 ) to impart a third pressure pulse in said working fluid medium in response to wave induced movement of said spring assembly ( 8 ), pump ( 14 a ) absorbing torsion stresses and pump ( 14 b ) absorbing vertical stresses exerted onto the spring assembly ( 8 ).
