Liquid tank buoy-type wave energy power generation device integrated to floating breakwater

Abstract

The invention belongs to the technical field of ocean energy utilization and provides a liquid tank buoy-type wave energy power generation device integrated to a floating breakwater. The liquid tank buoy-type wave energy power generation device comprises a floating breakwater structure and a liquid tank buoy-type wave energy power generation device body. The floating breakwater structure comprisescompartments and anchoring structures. Each compartment is divided into an upper part and a lower part through a partition board, the upper part serves as an equipment compartment used for containinga power generator and an energy storage tank, and the lower part serves as an airtight liquid tank. The liquid tank buoy-type wave energy power generation device body comprises buoys, pulleys, tracks, hydraulic power generators, springs, hydraulic rods and hydraulic cylinders. According to the liquid tank buoy-type wave energy power generation device, mechanical energy of external waves is gathered to the interiors of the hydraulic tanks through the hydraulic tank structures, and early loss of incident wave energy is reduced; the wave energy is extracted through the oscillating buoys in the compartments, and the utilization rate of the incident wave energy is increased. The buoy structures are arranged in the airtight hydraulic tanks filled with nitrogen, and corrosion and damage of the external waves to the buoy structures are avoided. The floating breakwater serves as a platform of the liquid tank buoy-type wave energy device and is fast in construction and easy to remove, and the construction scheme technology is mature.

Description

technical field [0001] The invention belongs to the technical field of ocean energy utilization, and particularly relates to a tank float type wave energy power generation device integrated in a floating breakwater. Background technique [0002] As the world's energy demand continues to grow, marine renewable energy, which has huge reserves and has not been widely utilized, has become the focus of attention. Among the various forms of ocean energy, wave energy with high energy density and wide distribution shows great application prospects. At present, there are thousands of related inventions of wave power generation devices in the world, but their commercial application is still limited by two problems of low wave utilization rate and high construction cost. [0003] The invention proposes a novel wave energy power generation system which can improve the utilization rate of wave energy and reduce the construction cost, that is, a tank float type wave energy power generati...
