Ocean wave energy power generation device

Abstract

The invention relates to an ocean wave energy power generation device. By the adoption of the ocean wave energy power generation device, the problems that reciprocating swinging is adopted by most existing wave energy power generation devices, efficiency is low, and losses of a power generator are large are solved. The ocean wave energy power generation device comprises a floating body which floats on the sea. A power generator is arranged in the floating body and connected with impellers horizontally stretching out of the floating body from the side faces. The ocean wave energy power generation device is characterized in that a plurality of off-center V-shaped grooves are evenly formed in the surface of the impeller and extend in the axial direction, blades which can swing to be buckled / unfolded are arranged in the V-shaped grooves, swinging shafts of the blades are arranged along the bottom of the V-shaped grooves, and the two side walls of each V-shaped groove are a buckled surface and an unfolded surface respectively; extension blades which can stretch out from the outer ends of the blades and are used for enlarging stress areas of the blades are further arranged in an inner cavity of the impeller in a clamped mode. According to the ocean wave energy power generation device, the impeller is kept rotating in one direction all the time in the waving process; in addition, the impeller can be propelled in a complex ocean current and wave flow combined form, the extension blades can stretch out when the blades are unfolded, and energy collection efficiency is improved.

Description

technical field [0001] The invention relates to a power generation device utilizing ocean energy, in particular to a power generation device for ocean wave energy. Background technique [0002] The ebb and flow of the ocean, the flow of ocean currents, and the ups and downs of waves all contain huge energy. In today's increasingly tense energy environment, ocean energy is a huge treasure house. Ocean tidal energy and wave energy are clean and pollution-free, and have great potential. At present, people The development of marine energy is just a drop in the ocean. [0003] At present, for the utilization of ocean wave energy, the traditional idea is to set up a float with a power generation device, and use the ups and downs of the waves to drive the pendulum to swing to drive the generator to work. For example, the patent application document CN103206338A published by the Chinese Patent Office on July 17, 2013, records a wave energy power generation device, which uses the pe...
