Description

technical field [0001] The invention belongs to the technical field of wave power generation, and in particular relates to a moon pool oscillating water column wave energy power generation device based on a floating breakwater. Background technique [0002] Energy is a hot topic in today's era. With the rapid development of the world economy, human demand for energy is becoming larger and larger. However, environmental pollution and the total amount of fossil energy are constantly decreasing, making people realize that the development and utilization of clean energy is imminent. Among them, the wave energy that can be provided in the ocean has the advantages of high energy density and wide distribution, and can provide energy relatively stably. At present, various forms of wave energy conversion devices have been widely studied, and how to efficiently harvest energy will become a major research focus. [0003] The development and utilization of wave energy in my country be...

AI Technical Summary

Problems solved by technology

However, because wave energy itself is a relatively unstable renewable energy source, the irregular generation of waves and the change of wave height make it difficult to be collected and captured.

Poor stability and low energy gathering efficiency lead to low utilization efficiency of the device

At the same time, these power generation devices are placed in the sea, but due to the surge of undercurrents and the uncertainty of sea conditions, once encountering strong winds, waves or bad sea conditions, the service life of these power generation devices will be greatly reduced
