A steward type universal wave energy conversion device

Abstract

The invention relates to a steward type universal wave energy conversion device. The steward type universal wave energy conversion device comprises a floater, an adjusting platform, an adjusting oil cylinder, a guide rod set and a steward parallel mechanism which are sequentially arranged from top to bottom. The steward parallel mechanism comprises a moving platform, a power generation hydraulic oil cylinder or barrel-type linear generator set and a fixed platform which are sequentially arranged from top to bottom. The floater is rigidly connected with the adjusting platform, one end of the adjusting oil cylinder is hinged to the lower end of the adjusting platform, and the other end of the adjusting oil cylinder is hinged to the upper end of the moving platform. The guide rod set is arranged between the adjusting platform and the moving platform and guides the adjusting platform and the moving platform to get close to or away from each other. The height of the floater is adjusted through the adjusting oil cylinder. Working hydraulic cylinders or barrel-type linear generators in the power generation hydraulic oil cylinder or barrel-type linear generator set are connected with the moving platform and the fixed platform in a hinged manner. According to the steward type universal wave energy conversion device, the wave energy capturing efficiency is not influenced by the wave direction; and in addition, the floater can absorb the potential energy of waves and can absorb the kinetic energy of the waves.
