Square box type floating breakwater with oscillating water column type wave energy power generation device

Abstract

The invention discloses a square box type floating breakwater with an oscillating water column type wave energy power generation device. A wave water inlet is formed in the ahead sea face of the square box type floating breakwater, a generating set is arranged in an airflow channel, waves enter an air chamber from the water inlet of the ahead sea face of the square box type floating breakwater, and a water column which oscillates up and down is formed; the water column oscillates up and down to force air in the air chamber to be compressed and expanded, the air passes through the airflow channel on the top of the air chamber in a reciprocated manner, the generating set is pushed to generate power, through a transmission device, the electric quantity is stored in an energy storage device for standby application, and the breakwater has the advantages of being simple and stable in structure, low in building cost, high in power generation conversion efficiency, convenient to maintain, highin adaptation and the like and can be arranged on the coast, nearshore or offshore sea area, the ocean space is effectively used, the wave energy is converted into electric energy while the wave influence is reduced, and the stable water area environment is provided for the surrounding sea area, and the ocean wave resources are reasonably used.

Description

technical field [0001] The invention belongs to the technical field of marine engineering, and in particular relates to a square box-type floating breakwater with an oscillating water column type wave energy generating device. Background technique [0002] In order to solve the current energy supply problem that is essential for human development, it has gradually become the consensus of all countries in the world to find alternative, renewable, and clean new energy sources. New energy sources include ocean energy, biomass energy, wind energy, solar energy, geothermal energy, nuclear energy, etc. Ocean energy has attracted the attention of scientific researchers from all over the world because of its unique charm. As we all know, the surface of the earth is separated by major continents into vast waters connected to each other called oceans, with a total area of ​​about 360 million square kilometers, accounting for about 71% of the earth's surface area, and an average water ...

AI Technical Summary

Problems solved by technology

[0004] There are more or less defects in the current breakwaters. For example, according to the current research results, the most important factors affecting the wave dissipation performance of floating breakwaters are the dike width and draft. The wider the dike width and the deeper the draft, the better the wave dissipation. The effect is better, but with the increase of the main scale of the floating breakwater, its cost will increase significantly, and the wave force it receives will also increase, which will place greater requirements on the strength of the structure itself and the design of the mooring system, and Floating breakwaters have a good wave dissipation effect for short-period waves, but not obvious for long-period waves. Therefore, most current engineering applications place floating breakwaters in wave areas with smaller wave heights and shorter periods.
