The invention relates to the technical field of tide and wave energy conversion, in particular to a wave energy conversion device. The wave energy conversion device comprises a floating ball and a connecting rod, wherein an electric energy conversion device is arranged in the floating ball; the upper end of the connecting rod penetrates the floating ball and is connected with the electric energy conversion device; a plastic floater is arranged at the lower end of the connecting rod and comprises a fixed disc and a supporting ring, the fixed disc is connected with the connecting rod, a dampingmembrane is arranged between the fixed disc and the supporting ring and surrounds the fixed disc and the supporting ring to constitute a hollow circular truncated cone structure. The wave energy conversion device is reasonable in structure, thrust surface of the lower end of the connecting rod is increased by the plastic floater in a circular truncated cone shape, kinetic energy absorption rate ofthe floating ball is increased, so that energy conversion efficiency of the conversion device is increased, meanwhile, resistance borne by the connecting rod in a reset process is reduced, reset cycle is shortened, and accordingly, power generation conversion efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of tidal and wave energy conversion, in particular to a wave energy conversion device. Background technique [0002] With the continuous growth of human development needs, non-renewable petrochemical energy will gradually be exhausted. The most important research and exploration in the 21st century is the development and utilization of clean energy such as wave energy. At present, power generation devices that convert wave energy into electrical energy can be divided into mechanical, pneumatic and hydraulic types according to their structural characteristics. Common conversion devices are often bulky in structure, poor in corrosion resistance and reliability, and thus difficult to be practically applied in marine environments. The parts of these power generation devices that absorb tidal kinetic energy are the upper and lower floats. The upper and lower floats move up and down with the undulation of the wav...
