Description

帆船式水上风力发电机 技术领域
本发明涉及的是一种风力发电技术领域的装置， 具体是一种帆船式水上风力 发电机。 背景技术
现有技术通常所使用的风力发电的设备对风速要求较高， 严重影响了发电量， 现在已经成形的水平轴及垂直轴发电系统造价都非常昂贵。 进口产品每千瓦单价
8000元至 10000元人民币， 国产的也要 5000元左右。 同时， 按现在的吊装设备的 局限， 也无法将发电机达到真正的大型化， 现在商业运行的单台风力发电机都在 1000 千瓦左右， 因此综合发电成本均高于火电成本。 这就影响了风力发电行业大 规模市场化运作。现阶段急需一种将风力发电领域的造价高、大型化、启动风速高、 稳定性差及维护成本高等难题一并解决的低成本风力发电技术，能一并满足上述条 件， 将海上风能这一自然资源加以利用。
经过对现有技术的检索发现， 中国专利申请号 200610021220. 8， 公开号 CN101092164A 的发明专利申请， 记载了一种 "帆船与水下风车相结合的水上风能 利用方法"， 该技术把用于洋流发电的水轮机安装于帆船上， 用风力驱动帆船， 产 生相对于帆船的水流驱动水轮机做功，然而该技术并未对具体实施有任何记载，从 而无法应用于实际产业中。
又经过对现有技术的检索发现， 中国专利申请号 200410075086. 0， 公开号 CN1587685A 的发明专利申请， 记载了一种 "风力发电装置"， 该技术由机房、 风 力驱动机构、变速箱和发电机组成， 其中： 风力驱动机构由转轴固定在转轴上三对 帆杆和安装在帆杆上的帆及转动齿轮组成；每对帆中，左右两侧的帆安装方向相反， 一侧为迎风正面时， 另一侧正好为迎风反面， 转轴随着力大的方向旋转， 旋转的转 轴通过转动齿轮。但该技术只能专用于陆地固定地点的风力发电，无法在水上实施; 另外由于该技术的浮帆及帆杆的质量均靠转轴支撑，使得转动摩擦力产生额外损耗 并导致转轴老化； 最终上述技术的结构特征限制了其实际应用时规格的设计上限， 使得风机在低风速环境下无法启动。 发明内容
本发明针对现有技术存在的上述不足， 提供一种帆船式水上风力发电机， 通 过分体式活动浮帆结构， 将浮帆及动力臂重量移至船体； 具有结构简单， 造价低， 适合除强台风外的高中低风速水上发电的大规模实施。
本发明是通过以下技术方案实现的， 本发明具体包括： 一个主壳体、 若干浮 帆、 动力臂及发电装置， 其中： 主壳体位于中心， 通过动力臂连接若干浮帆， 发电 装置位于主壳体内，发电装置的输入端连接至动力臂，发电装置的输出端连接至电 网。
所述的主壳体为防水型发电机舱体， 主壳体用防水结构支架固定于最高水位 以上， 或用防水结构支架定位后漂浮于水面。
动力臂包括： 一个中心转盘和若干个连接杆， 其中： 中心转盘固定连接于发 电装置的输入端，若干连接杆的一端转动设置于中心转盘上，连接杆的另一端转动 设置于对应的浮帆上， 中心转盘的转动平面平行于水平面。
所述的连接杆长度为 5米至 150米， 连接杆与水平面的夹角小于等于 35。 。 所述的浮帆数量至少为 3个， 分别平均环绕于主壳体圆周。
所述的浮帆包括： 帆体、 帆座、 帆杆和活动接头， 其中： 帆杆的一端固定设 置于帆座上， 帆体固定于帆杆的另一端， 活动接头连接设置于帆杆下部。
所述的风帆面积为 15平方米至 180平方米。
发电装置包括变速箱和发电机， 其中： 变速箱的输入轴连接动力臂， 变速箱 的输出轴连接发电机的输入轴， 发电机的输出端连接电网。
本发明还提供了另一种帆船式水上风力发电机， 包括一个主壳体、 至少三个 浮帆、 动力臂及发电装置， 其中， 上述的至少三个浮帆环设在主壳体的周围， 发电 装置位于主壳体内，发电装置的输入端连接至动力臂，发电装置的输出端连接至电 网；
动力臂包括一个中心转盘和多个连接杆， 多个连接杆分别设置在相邻的每两 个浮帆之间， 该多个连接杆的一端均与中心转盘相连， 并可带动中心转盘旋转； 中 心转盘固定连接于发电装置的输入端， 中心转盘的转动平面平行于水平面；
各浮帆包括帆体、 帆座和帆杆， 帆座的两端分别通过牵引索与位于该帆座两 端的两个连接杆的另一端相连， 帆杆固定设置于帆座上， 帆体固定于帆杆上； 上述的至少三个浮帆在风力的作用下产生带动中心转盘旋转的力矩。
本发明工作时主壳体固定于水上平台或浮于水面， 若干浮帆漂浮于水面并通 过风力驱动浮帆的帆体后进行转动发电。 在连接杆的一端转动设置于中心转盘上、 另一端转动设置于对应的浮帆的情况下，浮帆产生的浮力等于浮帆自身重力以及动 力臂的重力分量，使得最终发电机的主轴仅承受的动力臂余下的重力分量，大大减 少了摩擦阻力。 本发明在海上或内陆河道上实施时， 在周边风速为 3米 /秒以上的 环境下采用平面多轴型齿轮箱时可达到 1000〜1500转 I分的转速， 将水上风能采 集转化为电能。 附图概述

本实施例在具体工作时， 主壳体 1固定于设置于水上平台， 4个互成 90°的浮 帆 2漂浮于水面由风力驱动浮帆 2的帆体 5进行转动发电，当浮帆 2的正面迎风时， 通过帆网 11透风不产生阻力， 帆座 6由于船头迎风同样将阻力减小至最低； 当浮 帆 2的背面迎风时， 通过风帆 13阻风产生阻力， 帆座 6由于受风阻朝船头方向运 动， 由此 4个浮帆 2轮番转动驱动发电机发电。
本实施例中浮帆 2产生的浮力等于浮帆 2自身重力以及动力臂 3的重力分量， 使得最终发电机 15的主轴仅承受的动力臂 3余下的重力分量， 大大减少了摩擦阻 力， 使得本实施例在滩涂上实施时， 在周边风速为 8米 /秒时可达到 1200转 I分的 转速进行发电。 图 4至图 8示出了本发明的另一种实施方式的帆船式水上风力发电机， 其包 括一个主壳体 1、至少三个浮帆 2(图 4中示出了 4个浮帆 2)、动力臂 3及发电装置， 其中， 所述至少三个浮帆 2环设在主壳体 1的周围， 发电装置位于主壳体 1内， 发 电装置的输入端连接至动力臂 3， 发电装置的输出端连接至电网。 该发电装置的结 构与第一种实施方式相同， 在此不再赘述。 如图 2所示， 主壳体 1可悬浮于水面， 并通过链式绳索 16抛锚定位。
动力臂 3包括一个中心转盘 9和多个连接杆 10，该多个连接杆 10分别设置在 相邻的每两个浮帆 2之间， 该多个连接杆 10的一端均与中心转盘 9相连， 并可带 动中心转盘旋转。中心转盘 9固定连接于发电装置 4的输入端， 中心转盘 9的转动 平面平行于水平面。
各浮帆 2包括帆体 5、 帆座 6和帆杆 7， 帆座 6的两端分别通过牵引索 17与 位于该帆座两端的两个连接杆的另一端相连， 帆杆 7固定设置于帆座 6上， 帆体 5 固定于帆杆 7上。 帆座 6可采用船体式封闭结构。
请参阅图 6至图 8。 帆体 5包括风帆 13、 上横梁 18、 下横梁 19和两根钢丝绳 20。 风帆 13的正面朝向船头。 风帆 13上设有多个通孔 21， 多个通孔 21纵横排列 成多行和多列。 各通孔 21的上端连有一可覆盖住该通孔 21的活页 22， 通孔内设 有阻挡活页 22以使活页 22只能向风帆 13的背面侧摆动的阻隔件 23。该阻隔件 23 可以是如图 8所示的网格状阻隔件，也可以采用其它形状， 阻隔件的材料可以是纤 维织物、金属等。上横梁 18和下横梁 19分别固定在帆杆 7的上部和下部。两根钢 丝绳 20分别设置在风帆 13的两侧， 各钢丝绳 20的上端和下端分别固定在上横梁 18和下横梁 19上， 各钢丝绳上套设有多个圆环 24， 风帆 13的两侧分别与两根钢 丝绳上的圆环 24相连。 在帆座 6上还设有卷扬机 25， 卷扬机 25的钢丝绳 26绕过 固定于上横梁 18的滑轮 27后与风帆 13相连，带动风帆 13沿两根钢丝绳 20升降。 图中仅示出了一个风帆，也可根据需要在帆座 6上设置多个风帆，组成一风帆阵列。 当风帆 13的正面迎风时， 通过通孔 21透风使得活页 22向风帆 13的背面侧飘摆， 不产生阻力， 帆座 6由于船头迎风同样将阻力减少至最低； 当风帆 13的背面迎风 时， 活页 22由于受到通孔上的阻隔件 23的阻挡， 无法向风帆的正面飘摆， 从而产 生阻力， 帆座 6由于受阻朝船头方向运动， 由此至少三个浮帆轮番转动， 驱动发电 装置发电。这种风帆的结构与第一种实施方式相比， 由于无需采用帆框， 因而具有 降低成本的优点。
在本实施方式中， 浮帆 2的数量可采用 3至 10个， 该些浮帆分别平均环绕于 主壳体 1圆周。帆体 5也可采用第一种实施方式的帆体结构。帆体的结构应使得该 些浮帆 2在风力的作用下能够产生带动中心转盘 9旋转的力矩。
本实施方案的描述结合了特定的实施例， 但是本领域普通技术人员应该理解 本发明并不限于在此描述的实施例，并可以进行各种修改和变化而不背离本发明的 精神和范围。 工业应用性
本发明工作时主壳体固定于水上平台或浮于水面， 若干浮帆漂浮于水面并通 过风力驱动浮帆的帆体后进行转动发电。 在连接杆的一端转动设置于中心转盘上、 另一端转动设置于对应的浮帆的情况下，浮帆产生的浮力等于浮帆自身重力以及动 力臂的重力分量，使得最终发电机的主轴仅承受的动力臂余下的重力分量，大大减 少了摩擦阻力。本发明在海上或内陆水面上实施时，可将多个本发明的发电装置连 接后合并发电， 在周边风速为 3米 /秒以上的环境下采用平面多轴型齿轮箱时可达 到 1000〜1500转 I分的转速， 将水上风能采集转化为电能。
