Abstract

The invention belongs to the field of a novel renewable energy source technology and a marine device and in particular relates to a double-floating-body type wave energy power generation device utilizing a water turbine. The double-floating-body type wave energy power generation device comprises floaters, a piston, a connecting rod, a turbine generator, a hydraulic cabin and an anchor chain. The double-floating-body type wave energy power generation device is characterized in that the floaters are connected with the piston through the connecting rod; the piston is positioned in the middle of the hydraulic cabin; the hydraulic cabin is connected with a main water flow channel through a water outlet one-way valve; the turbine generator is arranged in the main water flow channel; the floaters move up and down along the water level change of the sea surface to drive the piston in the hydraulic cabin to move to further ensure that liquid in the hydraulic cabin flows to drive the turbine generator to generate power. According to the double-floating-body type wave energy power generation device disclosed by the invention, wave energy is converted into electric energy by utilizing the change of the water level of the sea surface along the wave transfer; the double-floating-type wave energy power generation device is applicable to a deepwater area, provides electric power for offline facilities, such as seaborne beacon lights and observation stations, simultaneously has relatively reliability and is easy to mount and move.

Description

technical field [0001] The invention belongs to the field of novel renewable energy technology and marine equipment, in particular to a double-floating body type wave energy generating device utilizing water turbines. Background technique [0002] With the development of the world economy, the increase of population, and the continuous improvement of social living standards, the demand for energy in various countries is growing rapidly. In recent years, driven by the depletion of fossil energy, energy supply security, and environmental protection, ocean energy, one of the major renewable energy sources, has made great progress, and ocean energy application technologies have become increasingly mature, providing human beings with the opportunity to make full use of ocean energy in the 21st century. A bright future is shown. At present, the main wave energy devices in the world can be divided into three categories according to their basic principles of power generation: oscil...
