AI Technical Summary

Problems solved by technology

Especially under the action of short waves, due to its weak transmission ability, large reflections will be generated in front of the device, which will not only lead to low energy conversion efficiency of the device, but also generate large wave loads, threatening the safe operation of the device

Abstract

The invention belongs to the field of new energy technology utilization, and provides a floating type double-air-chamber oscillating water column wave energy power generation device with an external permeable structure, which comprises a permeable structure, an oscillating water column system and an anchoring fixing system. The floating type double-air-chamber oscillating water column wave energy conversion device and the permeable structure are effectively combined, so that the energy conversion efficiency of the device can be improved, and the effective frequency band width of the device is widened; and meanwhile, certain energy dissipation can be conducted on waves, especially short waves, through the permeable structure, the wave load borne by the device is reduced, and the survivability of the device is improved.

Description

technical field [0001] The invention relates to a floating double air chamber oscillating water column wave energy conversion device with an external air-permeable structure, which belongs to the field of new energy technology utilization. Background technique [0002] The vast ocean is rich in renewable energy. As a kind of ocean energy renewable energy, wave energy has huge reserves. The development and utilization of wave energy resources can effectively alleviate the shortage of traditional fossil energy and the environmental pollution caused by the use of fossil energy. , so wave power generation has broad application prospects. According to the working principle, wave energy power generation devices are mainly divided into three types: oscillating water column type, over-wave type, and oscillating body type. Among them, the oscillating water column wave energy device is not easy to corrode because its air turbine does not directly contact with seawater, and the device ...
