【具体实施方式】
下面结合附图对本发明进行详细说明:
实施例 1: 一种静水层波浪能发电装置, 包括能够随波浪上下往 复的浮体 5, 所述的浮体 5下方连接有水流导向加速盘 2, 所述的水 流导向加速盘 2包括盘体 201,所述的盘体 201包括外圈体 2010,所 述的外圈体 2010内设有盘心体 2011, 所述的外圈体 2010与所述的 盘心体 20U之间环状分布设置有多个倾斜方向相同的倾斜的导流板 2012, 所述的外圈体 2010与所述的盘心体 2011 以及相邻两导流板 2012之间形成水道 202, 所述的水道的出水口 2022处设有卡装在水 流导向加速盘 2上并可相对其转动的叶轮 1, 所述的叶轮 1上环状分 布设置有多个叶片 101, 所述的叶片 101与所述的出水口 2022相对 使得水流从所述的出水口 2022流出冲击所述的叶片 101带动叶轮 1 转动, 所述的水流导向加速盘 2内设有容置空间 208, 所述的容置空 间 208内设有由所述的叶轮 1带动其转子 402转动的发电机 4。 发电 机 4外做必要的防水密封。所述的水流导向加速盘 2为两个,分别设 置在所述的叶轮 1上下两侧。
所述的容置空间 208设置在所述的盘心体 2011靠所述的叶轮 1一侧中部, 所述的发电机 4的外定子 401固定连接在所述的盘心体 2011上, 所述的发电机 4的内转子 402连接在所述的叶轮 1的转轴 102上并由转轴 102带动转动。
所述的发电机 4可以只在叶轮 1上侧或下侧的水流导向加速盘 2内设置, 也可以上下两侧同时设置, 所述的发电机 4的转子 402还 可以固定套装在所述的叶轮 1的外侧,所述的容置空间 208延伸至叶 轮 1的外侧,所述的定子 401固定在所述的容置空间 208内套在转子 外。
所述的所述的盘心体 2011和所述的外圈体 2010至少一个为锥 形体使得所述的水道 202截面渐变, 所述的出水口 2022较小。
所述的外圈体 2010为圆筒形, 所述的盘心体 2011为圆锥体。 所述的导流板 2012设置在外圈体 2010底部, 所述的外圈体
2010顶部与盘心体 2011形成入水腔 2015。
所述的叶片 101为弧形片,所述的叶片 101的凹面朝向出水口
2022使得水流流出所述的的出水口 2022冲击所述的叶片 101凹面。
所述的浮体 5下方连接有下行加压盘 6, 所述的下行加压盘 6 内设有容水腔 601, 所述的容水腔 601顶部开口、 底部设有漏水小孔
602 ο
所述的外圈体 2010外侧设有多个竖向防转板 205,所述的竖向 防转板 205的竖向高度远大于厚度,所述的下行加压盘 6外侧设有多 个防转耳板 603, 所述的竖向防转板 205与所述的防转耳板 603固定 连接。
所述的浮体 5为中空的封闭腔体。
所述的导流板 2012为螺旋状倾斜。
所述的叶轮 1两侧的水流导向加速盘 2的出水口 2022出水方向 均与所述的叶片 101的凹面相对使得水流从所述的出水口 2022流出 冲击所述的叶片 101朝同一个方向转动。当发电装置向上运动时,水 从所述的叶轮 1上侧的所述的水流导向加速盘 2上侧流入水道 202内 从叶轮 1上方的出水口 2022流出冲击叶片 101, 带动叶轮 1转动; 当发电装置向下运动时,水从所述的叶轮 1下侧的所述的水流导向加 速盘 2下侧流入水道 202内从叶轮 1下方的出水口 2022流出冲击叶 片 101, 带动叶轮 1转动; 上下侧水流导向加速盘 2的水道螺旋方向 相反使得叶轮 1始终朝同一方向转动。
当发电装置随波浪向上运动时,由所述的浮体 5的浮力克服整个 发电装置的重力及下部装置的阻力使其不会完全下沉,这样就可实现 装置整体随波浪向上移动的目的。在所述的容水腔 601内的水上表与 海水相通, 不产生浮力, 当发电装置随波浪向下运动时, 所述的容水 腔 601内的水不会很快从漏水小孔 602排出,而且由于下部装置(下 进水口)的阻力让容水腔 601的水突出水面, 当水的重力与阻力相等 时水的重力作用就下压发电装置增大向下运动的下压力以增大转轴 的转动力矩。
实施例 2: 与实施例 1的区别在于所述的容置空间 208内设有由 所述的叶轮 1驱动的空气压缩机 8, 所述的空气压缩机 8的进气口和 出气口分别连接有伸出水面的进气管 9和出气管 10, 所述的出气管 10与用于带动发电机发电的气压马达 11相连。
所述的空气压缩机 8为螺杆式空气压缩机, 包括压缩机壳体 801, 所述的压缩机壳体 801内设有相互啮合的主转子 802和副转子 803。
所述的水流导向加速盘 2可以是两个, 分别设置在所述的叶轮 1 上下两侧,两个所述的水流导向加速盘 2内均设有所述的空气压缩机 8。两个空气压缩机的压缩气体汇集后输送到气压马达上作为动力源。
所述的空气压缩机 8也可以为涡旋式或者活塞式等其他类型的 空气压缩机。
发电机可以放置在浮体上面,也可以把出气管引到装置以外的地 方(海上平台或陆地上)推动气压马达带动发电机发电, 这样是可以 简单的将多个高压气汇集在一起驱动一个大的发电机发电,还可以将 汇集的高压气源通过气路分别带动不同的发电机发电。
实施例 3: 与实施例 2的区别在于所述的容置空间 208内设有由 所述的叶轮 1驱动的液压泵 15, 所述的液压泵 15的进油口和出油口 分别连接有伸出水面的进油管 16和出油管 17, 所述的进油管 16和 出油管 17分别与用于带动发电机发电的液压马达 19相连。 液压泵 与液压马达之间也可以通过液压阀等液压元件连接。
所述的液压泵 15为螺杆式液压泵, 包括壳体 151, 所述的压壳 体 151内设有相互啮合的泵主转子 152和泵副转子 153。 所述的液压泵 15也可以为涡旋式或者活塞式等其他类型的液压 泵。
发电机可以放置在浮体上面,也可以把进油管 16和出油管 17引 到装置以外的地方(海上平台或陆地上)推动液压马达带动发电机发 电,这样是可以简单的将多个液压回路的液压油汇集在一起驱动一个 大的液压马达从而驱动发电机发电,还可以将汇集的高压液压回路通 过管路分别驱动不同的液压马达及发电机发电。
