如图 1、 图 2、 图 3、 图 4、 图 5和图 6所示本发明一种蜂巢板制成的垂 直轴风力发电机， 支撑轴 1和风轮 2， 支撑轴 1垂直于地面， 风轮 2旋转方 向与地面平行， 风轮 2与支撑轴 1连接， 其中， 风轮 2包括叶片 22， 叶片 22 为长条形， 叶片 22包括上端面 2201、 下端面 2202、 迎风面 2203和受风面 2204,迎风面 2203和受风面 2204拼合且围成筒状体，上端面 2201与下端面 2202封盖住筒状体的两端开口， 筒状体内有支撑梁 2205; 上端面 2201、 下 端面 2202、迎风面 2203、受风面 2204及筒状体内的支撑梁 2205由蜂巢板制 成， 形成支撑梁 2205 的蜂巢板横向两端与形成迎风面 2203及受风面 2204 的蜂巢板连接并形成支撑，形成支撑梁 2205的蜂巢板纵向两端与所述上端面 2201和下端面 2202的蜂巢板连接。由蜂巢板围成叶片 22的基本形状使叶片 22质量更轻， 且蜂巢板有较高的强度质量比， 使本发明在质量较轻的前提下 可获得较高的强度， 从而能提高风能利用效率并提高风叶的使用寿命， 支撑 梁 2205使叶片 22不易变形，根据叶片 22剖面形状的大小可设置一条支撑梁 2205也可以设置多条相互平行的支撑梁 2205， 设置多条支撑梁 2205可以适 应较大的叶片 22剖面形状， 还可在叶片 22表面涂覆保护层防止蜂巢般腐蚀 以提高叶片 22的使用寿命。
进一步的， 风轮 2包括一对平行设置的扁平状支撑部件 21 , —对支撑部 件 21横截面中心设有通孔 211 ;
支撑轴 1横截面形状与一对支撑部件 21横截面中心的通孔匹配 211，支 撑轴 1插入一对支撑部件 21横截面中心的通孔 211，并贯穿一对支撑部件 21， 称位于支撑轴 1上部的支撑部件 21为上支撑部件 2101， 位于支撑轴 1下部 的支撑部件 21为下支撑部件 2102;
一对支撑部件 21之间设有长条状叶片 22，叶片 22有多片，多片叶片 22 一端与上支撑部件 2101连接且连接部位均匀分布于上支撑部件 2102横截面 周向，另一端与下支撑部件 2101连接且连接部位均匀分布于所述下支撑部件 横截面周向； 多片叶片 22的上端面 2201于迎风面 2203—侧边线围成上支撑部件 2101 横截面周线形状，多片叶片 22下端面 2202于迎风面 2203—侧边线围成下支 撑部件 2102横截面周线形状；
多片叶片 22的受风面 2204围成腔体， 腔体容纳支撑轴 1， 且不妨碍所 述支撑轴 1 自由转动；
多片叶片 22中的每片叶片 22与上支撑部件 2101及下支撑部件 2102连 接部位有旋转装置；
旋转装置内设有定位部件， 定位部件锁定旋转装置。
本发明的原理是,多片叶片 22通过旋转装置围拢时整个风轮 2呈柱形或 者台形， 在风力较大时可降低受风面积， 保护风轮 2。 本发明可以制成传统 的内转子形发电机也可制成外转子型发电机， 当制成内转子型发电机时风轮 2与转轴 1 同时转动成为转子， 并设置额外的定子， 制成外转子型发电机时 可将风轮 2设置为转子， 转轴 1设置为定子即可实现外转子型发电机。
进一步的，一对平行设置的扁平状支撑部件 21为圆环形且大小相同，叶 片 22为柱形体；
圆环形支撑部件 21以多条连接其外圆 211和内圆 212的等分线分成与多 片叶片 22数相同个等分， 取其中一条等分线称为当前等分线 213， 当前等分 线 213与圆环形支撑部件 21外圆 211的交点称为当前等分线 213的外节点 2131 , 圆环形支撑部件 21外圆 211上当前等分线 213的外节点 2131的逆时 针方向的前一个由其他等分线与外圆 211相交形成的外节点称为当前等分线 213的前节点 2132;
柱形体任一端面包括头部 2211和尾部 2212， 头部 221 1为圆形， 圆形头 部 2211直径等于圆环形支撑部件 21的外圆 211半径减去内圆 212半径之差， 圆形头部 2211的圆心位于一条等分线中点， 称一端面圆形头部 2211位于当 前等分线 213中点的柱形体为当前柱形体 221， 该端面为当前端面 2210， 称 当前柱形体 221沿圆环形支撑部件 21逆时针方向的第一个柱形体为第二柱形 体 222，称当前柱形体沿圆环形支撑部件 21逆时针方向的第二个柱形体为第 三柱形体 223，当前等分线 213的外节点 2131通过一条圆弧与当前等分线 213 的前节点相连称为外圆弧 2213， 做一圆形， 使该圆形与当前端面 2210的圆 形头部 2211外切， 与第二柱形体 222的与当前端面 2210同一平面内的端面 的圆形头部 2211内切， 并与第三柱形体 223的与当前端面 2210同一平面内 的端面的圆形头部 2211 外切， 以该圆形与当前端面 2210的圆形头部 221 1 的切点 2133至当前等分线 213的前节点 2132截取圆弧， 称该段圆弧为内圆 弧 2214， 外圆弧 2213与内圆弧 2214于当前等分线 213的前节点 2132处相 交形成当前端面 2210的尾部 2212， 外圆弧 2213半径与圆环形支撑部件 21 外圆 211半径相等，外圆弧 2213与内圆弧 2214及圆形头部 2211 自当前等分 线 213外节点 2131顺时针至内圆弧 2214与圆形头部 221 1切点 2133处截取 的圆弧围成当前端面 2210;
任一柱形体上下端面的圆形头部 2211圆心与相邻的支撑部件 21铰接， 任一柱形体以其上下端面的圆形头部 2211的圆心连线为轴枢转。
同时叶片 22的柱形体结构对一对圆环形支撑部件 21起到支撑作用， 尤 其是柱形体上下端面的圆形头部 2211的部位形成的圆柱体形状，可以有效的 支撑一对圆环形支撑部件 21， 分担支撑轴 1的受力， 延长支撑轴 1的使用寿 命， 且在设计成外转子的场合， 可在支撑轴 1中设置线圈或者永磁体， 由于 柱形体分担了支撑轴 1的受力， 使支承轴 1在强度上的要求降低， 使整个发 电机的设计更加灵活方便。 上述描述是建立在风轮 2顺时针转动的基础上， 逆时针转动的风轮 2只 需将上述当前等分线 213的前节点 2132定义成顺时针方向的前一条等分线于 圆环形支撑部件 21外圆 211的交点， 同时将第二柱形体 222和第三柱形体
223的方向定义在顺时针方向即可。
进一步的，任一柱形体与支撑部件 21铰接部位设有与柱形体联动的从动 齿轮 23， 从动齿轮 23平行于支撑部件 21， 且与其所属柱形体的任一端面的 圆形头部同心，支撑轴 1设有驱动齿轮 11，从动齿轮 23与驱动齿轮 11啮合。
以上实施方式可以通过一个驱动装置驱动支撑轴 1 旋转带动驱动齿轮 11 , 进而带动从动齿轮 23转动， 从动齿轮 23带动叶片 22传动， 实现叶片 1 1开合， 由于叶片 22两端都设有从动齿轮 23，这样可以使叶片 22开合时受 力均勾， 在叶片 22纵向尺寸很大时也能平稳开合。 进一步的， 上述实施方式还可以改进成， 以驱动装置直接驱动驱动齿轮
11， 以驱动装置驱动直接驱动齿轮 1 1， 使得支撑轴 1不须旋转， 即可实现叶 片 22开合， 由于风力发电机一般高度较大， 支撑轴 1通常都较长， 驱动支撑 轴 1旋转会消耗较多能源，设置额外的驱动装置驱动驱动齿轮 11可节省能源 同时避免支撑轴 1因旋转产生磨损。 还可以增加控制装置和感应装置， 控制 装置与驱动装置连接， 感应装置与控制装置连接， 感应装置感应风速后传递 信号至控制装置，控制装置根据当前风速指令控制装置调整叶片 22的开合角 度， 使本发明能提高风能利用效率同时有效保护风轮 2。
进一步的， 从动齿轮 23上可以设置定位销孔 231， 支撑部件 21上可以 设置与定位销孔匹配 231的定位销子 24， 还包括伸缩装置， 伸缩装置与定位 销子 24连接， 伸缩装置与控制装置连接。 伸缩装置控制定位销子 24伸出或 者縮回， 定位销子 24伸出时插入从动齿轮 23上的定位销孔 231中， 使从动 齿轮 23无法旋转，进而锁定叶片 22以实现定位的功能，定位销子 24缩回时 动齿轮 23解除锁定使叶片 22得以转动， 由控制装置控制伸缩装置动作使得 叶片 22的锁定与解除锁定可以远程实现。定位销孔 231可以设置多个，多个 定位销孔 231呈以从动齿轮 23轴芯 230为圆心的圆环状分布于从动齿轮 23 上。设置圆环状分布的多个定位销孔 231使叶片 22可以呈多种角度定位，定 位销子 24也可以设置多个，多个定位销子 24可以在叶片 22定位时使受力均 匀分配， 延长单个定位销子 24的使用寿命。 定位销子 24为圆柱形， 圆柱形 插入从动齿轮 23上的定位销孔 231中，定位销子 24的纵向截面可制成梯形， 或者将圆柱形插入定位销孔 231的部分制成半球形， 这样可以方便定位销孔 231与定位销子 24对位， 以避免从动齿轮 23与驱动齿轮 11使用时间过长出 现偏移的情况下定位销子 24无法伸入定位销孔 231的情况发生。
进一步的， 风轮 2可以设置多个， 多个风轮 2同心， 多个风轮 2旋转方 向相互平行， 多个风轮 2以相同的角速度旋转， 设置多个风轮 2是每个风轮 2的叶片 22不必过长， 可以降低叶片 22的加工难度， 同时提高叶片 22的强 度。 在此基础上， 多个风轮 2于垂直方向相互紧贴且每个风轮 2的支撑部件 21大小相同， 多个风轮 2的叶片 22数不同， 其中位于上部的风轮 2的叶片 可以少于位于下部的风轮 2的叶片，在上述基础上本发明可以以下形式实施， 位于最上部的风轮 2的叶片 22数为 2片， 往下依次每个风轮 2的叶片 22数 增加 1片， 风轮可以设置 5-7个， 叶片 22的柱形体对风轮 2的一对支撑部件 21起到了支撑作用， 每个风轮 2的叶片 22的柱形体又对相邻的风轮 2的支 撑部件 21起支撑作用，使整个风轮系统结构得到加强， 同时处于转轴 1下方 的风轮 2的叶片 22多于处于转轴 1上方的风轮 2，由于每个风轮 2的叶片 22 合拢后都围成直径相同的圆柱体， 使得叶片 22多的风轮 2的叶片 22打开后 的旋转半径小于叶片 22少的风轮 2，进而令整个风轮系统呈上大下小的形态， 由于离地越高风力越大， 上大下小的风轮系统可以更有效地利用风能， 同时 由于离地面越近风轮的旋转半径越小， 使得靠近风力发电机的土地在一定高 度范围内可以得到利用；在此基础上， 由于每个风轮 2所包含的叶片 22数目 不同， 使得每个风轮 2的固有频率不同， 多个风轮 2旋转时每个风轮 2旋转 产生的谐波分量相互干扰，使得每个风轮 2产生共振的频点发生改变， 同时， 由于每个风轮 2所包含的叶片 22数目不同，使得多个风轮 2在以相同角速度 旋转时不同的风轮 2的风轮叶片 22产生的气流相互干扰，从而阻碍了气动激 振的产生。 虽然上述实施方式在风能利用率上略低于单风轮结构的蜂巢板制 成的垂直轴风力发电机， 但是却能延长风力发电机风轮的寿命， 减少重因复 制造风力发电机风轮所消耗的能源。
进一步的， 还包括发电机， 发电机置于支撑轴 1的底部， 发电机通过传 动机构与风轮 2连接。 可将发电机置于地面， 甚至是地下， 通过传动装置与 风轮 2连接， 将发电机位置降低可以方便发电机的维修和保养， 此实施方式 下不适合设计成外转子型风力发电机的场合。
以上所述仅为本发明较佳的实施例， 并非因此限制本发明的申请专利范 围， 所以凡运用本发明说明书及图示内容所作出的等效结构变化， 均包含在 本发明的保护范围内。
