A wave energy collecting device comprises an array of modules, each including three pairs of buoyant members arranged in a circular configuration, a tubular shaft connector interconnecting each pair of buoyant members, and a trilateral radial plank member comprising three identical equidistantly spaced members located centrally within the circular configuration. Each of the three members of the plank member is linearly connected to a member of the plank member of an adjacent module through a spring assembly and perpendicularly connected with a pivotally hinged shaft of a corresponding tubular shaft connector. A working fluid medium flows within a pipe network lined along sequential members. An array of pumps mounted onto each buoyant member, another array of pumps mounted adjacently each spring assembly and another array of pumps mounted adjacently each shaft, impart wave induced pressure pulses into the working fluid medium, which is subsequently converted into energy.
