[5] D近年来， 人们提出了釆用 H型风叶来代替传统圆弧形双风叶的结构， H型 垂直轴风力发电机的风叶是釆用空气洞力学原理， 针对垂直轴旋转的风洞模拟 ， 风叶釆用飞机翼形形状， 在风轮旋转吋， 它不会受到因变形而改变效率等； 它用垂直直线 4-5个风叶组成， 由 4角形或 5角形形状的轮毂固定、 连接风叶的连 杆组成的风轮， 由风轮带动稀土永磁发电机发电送往控制器进行控制， 输配负 载所用的电能。  [5] In recent years, it has been proposed to use H-shaped blades instead of the traditional circular-shaped double-blade. The blades of H-type vertical-axis wind turbines are based on the principle of air tunnel mechanics. The wind tunnel simulation, the wind blade uses the shape of the wing of the aircraft. When the wind wheel rotates, it will not be affected by the deformation and change efficiency; it is composed of 4-5 blades of vertical straight lines, and is shaped by a quadrangle or a pentagon. The wind wheel is composed of a fixed wheel and a connecting rod connecting the blades, and the rare earth permanent magnet generator is driven by the wind wheel to send power to the controller for control, and the electric energy used for the load is matched.
[6] D根据 H型风力发电机的原理， 风轮的转速上升速度提高较快 （力矩上升速度 快） ， 它的发电功率上升速度也相应变快， 发电曲线变得饱满。 在同样功率下 ， 垂直轴风力发电机的额定风速较现有水平轴风力发电机要小， 并且它在低风 速运转吋发电量也较大。 这种 H型风力发电机的风叶***虽然有上述优点， 但是 ， 在风轮的转速上升速度及发电曲线方面也还存在许多需要改进之处。  [6] D According to the principle of H-type wind turbine, the speed of the wind turbine increases faster (the speed of torque rises faster), and the speed of power generation increases accordingly, and the power generation curve becomes full. At the same power, the vertical axis wind turbine has a lower rated wind speed than the existing horizontal axis wind turbine, and it also generates a large amount of power at low wind speeds. Although the blade system of the H-type wind turbine has the above advantages, there are still many improvements in the speed of the wind turbine and the power generation curve.

[33] D请参见图 1， 它是一种垂直轴风力发电机的风叶***， 包括两片风叶 1， 在每 片风叶 1的水平方向平衡轴线 2 (图中虚线） 的上方设有平行于水平方向平衡轴 线 2的风叶轴 3， 本发明中的水平方向平衡轴线 2是一根假想线， 它假想水平方向 平衡轴线 2的水平方向， 该风叶 1正好上下平衡。 在无风状态下， 风叶可以沿风 叶轴 3垂直竖立； 本发明中所述风叶轴 3与水平方向平衡轴线 2之间的距离 H要满 足风叶轴 3上、 下的力差 （本实施中为重力差， 当然， 也可以人为的设置其它作 用力， 如用扭力、 拉力等作用力， 关于这种作用力的实例在后叙述） ， 使风叶 1 在无风状态下， 风叶 1由水平状态能迅速地转为垂直状态 （本例中， 就是重力差 能使风叶 1在无风状态下迅速由平行于地面转为垂直于地面即可） ， 在有风状态 下风叶 1可以沿风叶轴 3旋转； 风叶轴 3的一端与垂直于地面的风轮轴 4固定连接 ， 风轮轴的另一端与发电机 5的转子轴相接， 风叶 1与风叶轴 3活动连接， 本例中 ， 所述风叶 1包括边框 11和设置在边框 11内的档风面 12， 在所述边框 11的相对两 竖直的边框上各设有一个轴承 13， 所述轴承 13设置在所述风叶轴 3上； 风叶 1的 档风面 12与风叶轴 3的轴线在同一平面内， 在风叶轴 3上设有用于限制风叶 1在垂 直状态吋， 只能单向水平转动的限制器 14， 本例中， 限制器 14是在当风从纸面 吹向观图者的方向吋， 限制器 14正好顶在图中左边的风叶 1的边框上， 使用图中 左边的风叶 1不能继续向观图者方向转动， 具有最大风阻， 而图中右边的风叶 1 ， 沿风叶轴 3在风的作用下， 水平旋转接近水平， 具有最小风阻， 从而对风叶轴 3形成一个力矩， 使风叶轴 3旋转， 带动发电机 5发电。 当图中左边的风叶 1向另 一侧旋转 180度吋， 同样是在风力的作用下， 该风叶 1就会被风吹为水平状态 (· 如图中右边风叶所示， 图中右边风叶并没有完画为水平状态， 主要是为了便于 说明及视图） ， 此吋， 该风叶风阻最小， 有利于风叶***旋转。 这种两个风叶 1 的风叶***， 在启动吋， 可能会存在死点 （如图中所示旋转到 90度吋） 的问题 ， 这吋， 只需要在该死点处， 施加一个外力， 使其越过死点， 本发明就可以在 惯性的作用下， 周而复始的不停旋转。 为了精准地调整风叶轴 3与水平方向平衡 轴线 2之间的距离 H， 以使风叶***达到最佳效果， 可以在风叶 1上或下设置配重 块 6。 本发明中的风叶 1既可以随着风叶轴 3沿着风轮轴 4公转， 也可以沿着风叶 轴 3单向水平转动。 [33] D See Figure 1, which is a blade system of a vertical axis wind turbine, comprising two blades 1 above the horizontal axis 2 (dashed line in the figure) of each blade 1 There is a blade shaft 3 parallel to the horizontal balance axis 2, and the horizontal balance axis 2 in the present invention is an imaginary line which assumes the horizontal direction of the horizontal axis 2, and the blade 1 is just balanced up and down. In the windless state, the blades may be vertically erected along the blade axis 3; in the present invention, the distance H between the blade shaft 3 and the horizontal balance axis 2 is to satisfy the force difference between the upper and lower blades 3 ( In this embodiment, the gravity difference is. Of course, other forces can be artificially set, such as using a force such as a torsion or a pulling force. An example of such a force will be described later, so that the wind blade 1 is in a windless state, the wind The leaf 1 can be rapidly changed from the horizontal state to the vertical state (in this case, the gravity difference can make the blade 1 quickly turn parallel to the ground to be perpendicular to the ground in the windless state), and the wind blade is in the windy state. 1 can be rotated along the blade shaft 3; one end of the blade shaft 3 is fixedly connected to the wind turbine shaft 4 perpendicular to the ground, the other end of the wind turbine shaft is connected to the rotor shaft of the generator 5, and the blade 1 and the blade 3 are movable. Connecting, in this example, the blade 1 includes a frame 11 and a windshield 12 disposed in the frame 11, and the opposite sides of the frame 11 A bearing 13 is disposed on each of the vertical frames, and the bearing 13 is disposed on the blade shaft 3; the wind surface 12 of the blade 1 is in the same plane as the axis of the blade shaft 3, and the blade shaft is 3 is provided with a limiter 14 for restricting the horizontal rotation of the blade 1 in a vertical state, which can only be rotated horizontally in one direction. In this example, the limiter 14 is in the direction when the wind blows from the paper surface to the viewer, the limiter 14 is exactly on the border of the blade 1 on the left side of the figure. The blade 1 on the left side of the figure cannot be rotated in the direction of the viewer. It has the maximum wind resistance, and the blade 1 on the right side of the figure is along the axis 3 of the blade. Under the action of the wind, the horizontal rotation is close to the horizontal level, and has the minimum wind resistance, thereby forming a moment on the blade shaft 3, causing the blade shaft 3 to rotate, and driving the generator 5 to generate electricity. When the blade 1 on the left side of the figure is rotated 180 degrees to the other side, the blade 1 is also blown horizontally by the wind under the action of the wind (· as shown in the right fan blade in the figure, The right side of the blade is not painted horizontally, mainly for the convenience of explanation and view). Therefore, the wind blade has the smallest wind resistance, which is beneficial to the rotation of the blade system. The blade system of the two blades 1 may have a dead point (rotated to 90 degrees 如图 as shown in the figure) after starting the ,, so that only an external force is applied at the dead point. By making it pass the dead point, the present invention can be rotated continuously under the action of inertia. In order to precisely adjust the distance H between the blade shaft 3 and the horizontal balance axis 2 to achieve the best effect of the blade system, the weight 6 can be placed above or below the blade 1. The blade 1 of the present invention may be revolved along the rotor shaft 4 along the wind turbine shaft 4 or horizontally along the blade shaft 3 in one direction.
[34] D 图 1中是以两片风叶 1对称设置对本发明的风叶***进行了解释， 实际上， 本 发明还可以设计成由三片风叶 1组成的风叶***， 这吋， 三片风叶最好设置成星 形结构， 即相邻两片风叶 1的风叶轴 3之间的夹角为 120度的结构。 同样的道理， 本发明还可以设计成由四片风叶， 五片风叶或六片风叶的结构， 被设置成四片 风叶， 五片风叶或六片风叶吋， 其各自相邻两片风叶 1的风叶轴 3之间的夹角最 好相等， 如四片风叶吋， 相邻两片风叶 1的风叶轴 3之间的夹角为 90度； 五片风 叶吋， 相邻两片风叶 1的风叶轴 3之间的夹角为 72度； 六片风叶吋， 相邻两片风 叶 1的风叶轴 3之间的夹角为 60度。 图 1中， 所述档风面 12所用材料为不透风纤维 布， 该纤维布要具有一定的抗拉力， 如帆布， 即可以承受一定的风力， 又具有 较轻的重量， 有利于安装和运输。 显然， 一切具有质量轻， 抗拉力强的软质材 料或硬质材料均可以使用， 如不透风无纺布等， 其中， 以具有抗拉力的质量轻 的软质材料为最优。 本发明中的限制器 14可以是直形的， 也可以是直角形的， 还可以其它几何形状， 只要能档住风叶 1， 保证其只能单向水平旋转即可以。 配 重块 6可以改善风叶轴 3两端的平衡， 使两端的面积差较大吋重力差减小， 使风 叶能在迎风减小、 在接***行地面状态， 在重力作用下快速转为垂直状态就足 够。 此重力差越小， 风轮轴两边风叶的风力差越大， 风能的利用率越高。 配重 块的重量很易调整， 位置可在风叶内或风叶外。 风叶 1为一平面， 以四边体为佳 ， 其四周为钢性管状结构， 中间平面可用帆布或足够拉力的不透风纤维组成， 重量减轻。 [34] D In Fig. 1, the blade system of the present invention is explained by symmetric arrangement of two blades 1 . In fact, the invention can also be designed as a blade system composed of three blades 1 . The three blades are preferably arranged in a star-shaped structure, that is, a structure in which the angle between the blades 3 of the adjacent blades 1 is 120 degrees. By the same token, the invention can also be designed as a structure of four blades, five blades or six blades, which are arranged into four blades, five blades or six blades, each of which has its own phase. The angle between the blades 3 of the adjacent two blades 1 is preferably equal, such as four blades, and the angle between the blades 3 of the adjacent blades 1 is 90 degrees; The angle between the blades 3 of the adjacent blades 1 is 72 degrees; the angle between the blades 6 of the adjacent blades 1 is 60. degree. In Fig. 1, the material of the windshield 12 is a non-permeable fabric, which has a certain tensile force, such as canvas, which can withstand a certain wind force and has a light weight, which is favorable for installation and transport. Obviously, all soft materials or hard materials with light weight and high tensile strength can be used, such as air-tight non-woven fabrics, among which soft materials with light tensile strength are preferred. The limiter 14 in the present invention may be straight or rectangular. Other geometries are also possible, as long as the vane 1 can be held, so that it can only be rotated horizontally in one direction. The weight 6 can improve the balance between the two ends of the blade shaft 3, so that the difference in the area between the two ends is larger, and the difference in gravity is reduced, so that the blade can be reduced in the windward direction, close to the parallel ground state, and quickly turned to the vertical under the action of gravity. The status is sufficient. The smaller the difference in gravity, the greater the wind difference between the blades on both sides of the wind turbine shaft, and the higher the utilization of wind energy. The weight of the counterweight is easily adjusted and can be placed inside the blade or outside the blade. The blade 1 is a flat surface, preferably a quadrilateral body, surrounded by a steel tubular structure, and the intermediate plane can be composed of canvas or a wind-tight fiber with sufficient tension, and the weight is reduced.

FIG. 6 is an embodiment of the present invention having four blades. In this embodiment, four blades are symmetrically disposed in two pairs, and two adjacent blades 1 are respectively arranged. The angle between the blades 3 is 90 degrees. In order to prevent the blade shaft 3 from being too long and the work enthalpy is unstable, in this example, the wind turbine shaft 4 is extended upward to form an extension 41, and the wind blade shaft 3 is pulled by the diagonal cable 42.

In this embodiment, the fan blade system further includes a wind blade 71, a turntable 72, a pull wire 73, and a bracket 74.

A system for increasing the attached blade 71 is mainly used when the blade 3 of the blade 1 is positively concentric with the horizontal axis 2 (ie, between the blade axis 3 and the horizontal axis 2) The distance H is equal to zero 吋). The air bearing blade 71 is added, and the wind blade 1 is in a balanced state, and the wind turbine blade 71 rotates under the action of the wind force, thereby rotating the turntable 72, and the turntable 7 2 pulls the pull wire, and the pull wire pulls the lower part of the wind blade, thereby breaking the wind. The balance of leaf 1 allows the entire system to work properly. The additional function of the attachment of the blade 74 is to cause the blade 1 to wind up and accelerate the horizontal rotation of the blade 1. Of course, the system for adding the blade 71 can also be used between the blade shaft 3 and the horizontal balance axis 2.

In this embodiment, the blade system may further include a wind direction detector 9 and a motor 10, the wind direction detector 9 controls the rotation of the motor 10 according to the wind direction, and the motor 10 drives the blade 1 to rotate, so that the blade 1 winds up. The 吋 is in a vertical state, and the leeward wind is horizontal. In this example, the wind direction detector 9 is disposed on the blade shaft 3. The motor 10 is disposed on the back of the blade 1 and drives the blade 1 to rotate horizontally through the teeth 101.
[40] D本发明的工作原理是有风吋， 由于风叶 1上下两端的面积不一样， 产生的风 力不一样， 此风力差大于风叶轴两端的重力差吋， 会使风叶 1以风叶轴 3为中心 水平旋转， 风力越大， 转动角度越大， 直到接近 90度与风向平行， 此吋风阻最 小。 对称于风轮轴 4的另一风叶 1， 此吋由于风叶 1的限制器 14的限制， 无法转动 ， 垂直于地面， 产生最大的阻力， 此吋风轮轴 4两边产生风力差， 使风叶 1以风 轮轴 4为中心旋转。 垂直的风叶 1沿风轮轴 4旋转大于 90度后， 由于风叶 1的限制 器 14是单方向限制， 此吋风叶 1沿风叶轴 3水平旋转， 减小风阻； 水平的风叶 1沿 风轮轴 4旋转 90度后， 此吋风叶 1与风向平行， 上下两端都无风阻， 由于风叶 1的 重力差， 风叶 1水平旋转 90度， 与地面垂直， 由于风叶 1的限制器 14的限制， 此 吋风叶产生最大风阻。 这样风叶 1不停的水平旋转、 由水平转为垂直， 又由垂直 转为水平， 阻力由最小变为最大， 由最大又变为最小， 使风叶沿风轮轴 4不停旋 转， 使风轮轴 4带动发电机 5旋转， 产生电力。 [40] D The working principle of the invention is windy. Because the area of the upper and lower ends of the blade 1 is different, the generated wind is different. The difference of the wind is greater than the difference in gravity between the ends of the blade, which makes the blade 1 The blade shaft 3 rotates horizontally at the center. The larger the wind, the larger the angle of rotation, and the wind resistance is minimized until it is nearly 90 degrees parallel to the wind direction. The other vane 1 is symmetrical to the wind turbine shaft 4, and the crucible cannot be rotated due to the limitation of the restrictor 14 of the vane 1, and is perpendicular to the ground, generating maximum resistance, and the wind deflecting on both sides of the hurricane axle 4 causes the vane 1 Rotates around the wind turbine shaft 4. After the vertical blade 1 rotates more than 90 degrees along the wind turbine shaft 4, since the limiter 14 of the blade 1 is unidirectionally restricted, the hurricane blade 1 rotates horizontally along the blade axis 3 to reduce the wind resistance; the horizontal blade 1 After rotating 90 degrees along the wind turbine shaft 4, the hurricane blade 1 is parallel to the wind direction, and there is no wind resistance at the upper and lower ends. Due to the gravity difference of the blade 1, the blade 1 is rotated 90 degrees horizontally, perpendicular to the ground, due to the blade 1 Limited by the limiter 14, this hurricane blade produces maximum wind resistance. In this way, the blade 1 rotates horizontally, from horizontal to vertical, from vertical to horizontal, and the resistance changes from minimum to maximum, from maximum to minimum, so that the blade rotates along the wind turbine shaft 4, making the wind The axle 4 drives the generator 5 to rotate, generating electric power.
