[0026] 所述圆柱环体 1采用圆形结构， 可以不受外海来浪方向的影响， 能适应各种浪 向。
[0027] 所述气室 3顶部采用半球环体 2， 气体经过半球环体 2进入气孔管道， 能有效减 少阻力， 并增大气流速度， 提高发电效率。
[0028] 使用在双向气流作用下均能同向旋转的涡轮发电装置 4， 气体进入和排出气室 吋都能发电， 提高发电效率。
[0029] 所述内部支撑圆柱 10设置在圆柱环体 1中轴线上， 能有效减少气室内部水面晃 荡。 [0030] 所述支撑圆台 9采用圆形结构， 在不同方向的波浪作用下， 能保持同样的受力 状态， 提高结构的可靠度。
[0031] 所述的振荡浮子 5采用圆柱形结构形式， 并且上下面的圆边处要进行光滑处理 以减少波浪在水平方向的作用力。
[0032] 所述的的活塞 7与气缸之间设有密封圈， 以防止气缸进水阻尼发电机锈蚀或者 进入泥沙。
[0033] 除上述实施例外， 本发明还可以有其他实施方式。 凡采用等同替换或等效变换 形成的技术方案， 均落在本发明要求的保护范围。
