Floating breakwater doubling as wave power generation device

Abstract

The invention relates to the technical field of breakwater engineering and wave power generation, in particular to a floating breakwater generation device arranged in open sea. The floating breakwater generation device comprises floating members, air turbine generator sets, air chambers, airflow passages, mooring systems and signal transmission devices, and is characterized in that the floating members are respectively connected with concrete anchor blocks at the sea bottom through anchor chains; a plurality of wave dissipating perforations penetrating through a floating body are formed in the head-sea face of each floating member; the air turbine generator sets are respectively arranged in the airflow passages; the floating bodies are driven by waves to vertically move, so that water in the air chambers vibrates and air in the air chambers is pushed to move, and the air turbine generator sets are further driven to generate electricity. The floating breakwater generation device disclosed by the invention has the characteristics of being stable in structure, low in erection cost, high in generation conversion efficiency, convenient to maintain, and the like, and can be applied to sea areas with deep water, high waves and complex terrain; while wave impacts are weakened and a steady water area environment is provided for surrounding water areas, the waves can be converted into electric energy, and the electric power supply problem of harbor district or island residents is effectively solved.

Description

technical field [0001] The invention relates to the technical fields of breakwater engineering and wave power generation, in particular to a floating breakwater power generation device arranged in the open sea. Background technique [0002] In the past 30 years, with the rapid development of deep-water berthing and deep-water oil extraction and mining operations, as well as the large-scale construction of offshore farms, the requirements for wave-proof structures have become higher and higher. Floating breakwater is a wave-proof structure that protects the internal facilities of the port or the coast. It is mainly to ensure the stability of the port and near-coastal waters, and to prevent waves from damaging port facilities and coastal erosion. It also has sand-proof, Anti-flow, anti-icing, diversion, and the inner side doubles as the function of the pier. Compared with traditional fixed breakwaters, floating breakwaters are more economical and portable; they are easy to in...

AI Technical Summary

Problems solved by technology

The disadvantages of the power generation breakwater devices mentioned in the above two patents are that the breakwater is not suitable for sea areas with large water depths, has a large dependence on the foundation, high cost, and a long construction period. The power generation device needs to be in direct contact with seawater. High requirements on anti-corrosion and sealing performance
