Wave jumping impeller type wave energy power generating device automatically lifting along with tide level

Abstract

The invention discloses a wave jumping impeller type wave energy power generating device automatically lifting along with the tide level. The wave jumping impeller type wave energy power generating device comprises a wave energy collecting and converting device to which a wedged body shrinkage wave path and a water draining pipeline are connected, wherein the wave energy collecting and converting device is mounted inside a buoyancy tank; the wedged body shrinkage wave path is arranged on the slope of the surface of the buoyancy tank and is communicated with a water inlet of the wave energy collecting and converting device; one end of the water draining pipeline is communicated with a water outlet of the wave energy collecting and converting device; the other end of the water draining pipeline is communicated with a water draining port arranged in the buoyancy tank; pile holes through which piles penetrate are uniformly distributed on the bottom surface of the buoyancy tank; the bottoms of the piles are fixed to base rock; the upper parts of the piles extend in pile sleeves arranged inside the buoyancy tank; the bottoms of the pile sleeves are fixedly sealed with the buoyancy tank; gearboxes which are internally provided with lift gears are connected to the pile sleeves in a sealing way; and the lift gears are meshed with lift racks fixed on the piles. The wave jumping impeller type wave energy power generating device disclosed by the invention can be arranged in different sea areas, adapts to various sea conditions and can automatically and stably adjust elevation along the fluctuation of the tide level so as to ensure the function of power generating efficiency.

Description

technical field [0001] The invention relates to the development and application of ocean wave energy in the technical field of renewable energy, in particular to a power generation device utilizing wave energy generated by ocean energy. Background technique [0002] In recent years, driven by the depletion of fossil energy, energy supply security, environmental protection and ecological balance, people have paid more and more attention to the development of new energy. 71% of the earth's surface area is the ocean with huge energy resources, among which wave energy is one of the most abundant energy resources in ocean energy. Utilizing marine energy has become the direction of energy research in the world today, and how to effectively utilize abundant and renewable marine resources is even more important. In 1992, the United Nations listed wave power generation as the top priority in the development of marine renewable energy. Coastal countries attached great importance to i...
