Self-floating body dual-drive wave energy collecting device

Abstract

The invention relates to a self-floating body dual-drive wave energy collecting device, and belongs to the field of green renewable energy sources for wave energy utilization. The self-floating body dual-drive wave energy collecting device comprises a mounting platform, wave energy collecting parts, double-ratchet parts, power shafts, a linkage part and rack supporting parts. The mounting platformis of a frame structure with self-buoyancy. Each wave energy collecting part comprises a floating body with four vertical through holes and two racks with opposite tooth surfaces, and the wave energycollecting parts are distributed and fixed to the mounting platform in a rectangular shape. The double-ratchet parts share an inner ring, two groups of same-direction pawls and two independent rotating outer rings which are arranged separately. The power shafts are used for gathering mechanical energy independently obtained by the multiple wave energy collecting parts into mechanical energy capable of achieving stable rotation. And the linkage device is used for gathering the rotary mechanical energy of all the power shafts into stable and uniform rotary mechanical energy and then transmitting the stable and uniform rotary mechanical energy to energy utilization parts. According to the self-floating body dual-drive wave energy collecting device, three-dimensional, random and inconstant natural attributes of natural waves are fully utilized, and wave energy collection is achieved.
