Abstract

The invention discloses a floated type wave power generation device and method. The floated type wave power generation device comprises a supporting frame arranged on the water, a controller, an annular buoy arranged on the edge of the supporting frame, a power generation device, an inclined guide rail arranged on the supporting frame, a supporting column used for supporting the inclined guide rail, a box body arranged on the inclined guide rail, a plurality of mooring ropes arranged on the supporting frame, a stay rope arranged on the box body and a lever located above the supporting frame. The floated type wave power generation device and method have the advantages that the application range is wide, the energy conversion efficiency is high and the safety performance is good.

Description

technical field [0001] The invention relates to the technical field of wave power generation, in particular to a suspended wave power generation device and method with high energy conversion efficiency and good safety. Background technique [0002] The development and utilization of marine energy is the direction of energy research. Under the situation that the earth's mineral energy is gradually depleted and the environmental situation is deteriorating, how to effectively use the abundant and renewable marine resources is very important; [0003] Wave energy is the cleanest renewable resource. The power of wave energy dissipated continuously along the coastline in the world reaches 27×105 MW, and the technically available wave energy potential is 10×105 MW. [0004] The existing wave power generation devices have the disadvantages of high price, low energy conversion efficiency and limited installation area. Contents of the invention [0005] The object of the present in...
