风洞式发电机  Wind tunnel generator
技术领域 Technical field
本发明涉及一种发电装置， 特别是一种利用风、 蒸汽、 水流的作用力驱 动叶片直接带动转子旋转的风洞式发电机， 它适用于多种发电场所。  The invention relates to a power generating device, in particular to a wind tunnel generator which uses the force of wind, steam and water to drive the blades to directly rotate the rotor, and is suitable for various power generating places.
背景技术 Background technique
目前， 广泛应用的发电机大多采用传统的汽轮发电机、 水轮发电机、 风 轮发电机、 柴油发电机等。传统结构大多是通过传动轴来驱动发电机转子旋 转， 传动轴受限于自重、 配套轴承大小等因素制约， 不宜制造特别大的结构 件， 故发电机转子和定子的制作就不可能超大型化， 因此对这种发电装置的 改进已成为人们普遍研究的对象。 本发明人曾设计一种风动发电装置（专利 公开号为 CN1807876A) , 该机采用带放风口和旋风导流道的聚风罩， 风洞、 叶轮及其带折角的叶片等多项技术， 来提高风能效力。但因其存在传动结构 复杂， 叶轮设计还不够合理单机容量并没有大的突破等缺陷， 有待进一歩改 进。专利公开号为 EP1350952A1的"配备垂直旋转的风力装置"中公开了一套 风力装备， 它配备一个垂直转子、 组装在转子底部以传动装置带动的一台发 电机、 组装转子上的大量用于驱动转子的叶片、 围绕转子径向布置的导向元 件系统， 并利用导向元件外壳中的顶盖作为活门， 通过调整盖上的配重的位 置来自动控制活门开启程度， 以调整聚风力大小达到最佳发电效果。 该装置 结构比较复杂， 安装、 调试很麻烦， 特别是对活门配重的调整， 必须要通过 一个测量系统来测定最大估计风力和最中风暴才能进行匹配。 若测量、估计 有误， 轻则影响发电效果， 重则损坏叶片。 公告号为 CN1237270C的"带罩 风力发动机"， 它主要包括一个发电机以及用于在风速小时增大吹向发电机 的风速的构件和在风速大时减少吹向发电机的风速的构件。它的主要作用是 减少聚风量， 而不是直接阻挡强风对叶轮叶片的冲击。 因其采用移动方式调 整发电机在导风件中的位置， 一旦传动装置失灵， 则无法移动发电机， 就起 不到调节风速的作用了。 以上两个对比文件均是解决聚风量大小的问题， 并 不能在超强风速时挡风， 功能比较单一。现有发电装置大多通过传动轴带动 发电机转子旋转， 尚无关于空心转子及叶轮直接带动转子旋转的报导。 发明内容 At present, most of the widely used generators use conventional steam turbine generators, hydroelectric generators, wind turbine generators, diesel generators and the like. Most of the traditional structures drive the rotor of the generator through the drive shaft. The drive shaft is limited by factors such as its own weight and the size of the bearing. It is not suitable to manufacture particularly large structural parts. Therefore, the rotor and stator of the generator cannot be made large. Therefore, improvements to such power plants have become the subject of widespread research. The inventors have devised a pneumatic power generating device (patent publication No. CN1807876A), which adopts a plurality of technologies such as a wind tunnel, a wind tunnel, an impeller and blades with angled angles, and the like, which adopts a wind vent and a cyclone guide. To improve the effectiveness of wind energy. However, due to its complex transmission structure, the impeller design is not reasonable enough. There is no big breakthrough in single-unit capacity, and it needs to be improved. A set of wind power installations is disclosed in the "Flat-rotating Wind Power Installation" of EP 1 309 052 A1, which is equipped with a vertical rotor, a generator assembled at the bottom of the rotor and driven by a transmission, and a large number of drives on the assembled rotor. The blade of the rotor, the guiding element system arranged radially around the rotor, and the top cover in the guiding element housing is used as a shutter, and the opening degree of the valve is automatically controlled by adjusting the position of the weight on the cover to adjust the size of the gathering wind to the best. Power generation effect. The structure of the device is complicated, and the installation and debugging are troublesome. Especially for the adjustment of the valve weight, a measurement system must be used to determine the maximum estimated wind and the most moderate storm to match. If the measurement and estimation are wrong, it will affect the power generation effect and damage the blade. The "Covered Wind Turbine" of the CN1237270C, which mainly includes a generator and a member for increasing the wind speed to the generator when the wind speed is small, and a member for reducing the wind speed to the generator when the wind speed is large. Its main role is Reduce the amount of airflow, rather than directly blocking the impact of strong winds on the impeller blades. Because it adjusts the position of the generator in the air guiding member by moving, once the transmission fails, the generator cannot be moved, and the wind speed is not adjusted. The above two comparison documents are all solutions to the problem of the amount of gathering air, and can not be blocked at super wind speed, and the function is relatively simple. Most of the existing power generation devices drive the rotor of the generator through the drive shaft, and there is no report about the rotor and the impeller directly driving the rotation of the rotor. Summary of the invention
本发明的目的是提供一种风洞式发电机， 它结构设计合理， 明显提高发 电效率， 其既能在风速较弱时聚风、 提高风能效力， 又能在超强风时避风， 有效地防止部件受损， 保障安全运行。  The object of the present invention is to provide a wind tunnel type generator, which has reasonable structural design and obviously improves power generation efficiency, and can not only gather wind when the wind speed is weak, but also improve the wind energy efficiency, and can avoid the wind when the wind is strong, effectively preventing Damaged parts ensure safe operation.
本发明的目的是这样实现的： 该机包括固定在转盘式基座上的带有可调 式风罩的机壳及组装其内的定子、 转子和叶片， 其技术要点是： 所述转子内 周与叶片顶部固定连接在一起， 转子通过轴承组装在定子内， 并使转子外周 的滑道沿机壳两侧的支撑板上的导轨转动，所述可调式风罩由铰接在连接板 周边的挡风板组成， 连接板固定在机壳的支撑板侧部， 液压缸的缸体端部通 过销轴铰接在连接板上， 液压缸的活塞头部铰接在挡风板上， 液压缸驱动挡 风板绕铰接轴摆动。  The object of the present invention is achieved as follows: The machine comprises a casing with an adjustable hood fixed to a turret base and a stator, a rotor and a blade assembled therein, the technical points of which are: the inner circumference of the rotor Fixedly coupled to the top of the blade, the rotor is assembled in the stator through the bearing, and the slides on the outer circumference of the rotor are rotated along the guide rails on the support plates on both sides of the casing, the adjustable hood being hinged to the periphery of the connecting plate The wind plate is composed, the connecting plate is fixed on the side of the support plate of the casing, the end of the cylinder of the hydraulic cylinder is hinged on the connecting plate through the pin shaft, the piston head of the hydraulic cylinder is hinged on the wind deflector, and the hydraulic cylinder drives the wind shield The plate swings about the hinge axis.
所述固定连接在转子内周的叶片的连接套组装在中心支撑轴上。  The connecting sleeve of the blade fixedly attached to the inner circumference of the rotor is assembled on the central support shaft.
由于本发明采用采用空心风洞式转子结构，且转子内周与叶片顶部固定 连接在一起， 转子通过轴承组装在定子内， 并使转子外周的滑道沿机壳两侧 的支撑板上的导轨转动， 所以风洞内的叶片可以直接驱动转子转动， 取消传 统的传动轴， 因此结构设计合理， 明显提高发电效率。 另外由铰接在连接板 周边的挡风板组成的可调式风罩， 在液压缸的驱动下自动调整进风口大小， 故既能在风速较弱时聚风、 提高风能效力， 又能在超强风时避风， 有效地防 止部件受损， 保障安全运行。 Since the present invention adopts a hollow wind tunnel type rotor structure, and the inner circumference of the rotor is fixedly coupled with the top of the blade, the rotor is assembled in the stator through the bearing, and the slide rail on the outer circumference of the rotor is along the guide rail on the support plate on both sides of the casing. Rotating, so the blades in the wind tunnel can directly drive the rotor to rotate, canceling the traditional transmission shaft, so the structural design is reasonable, and the power generation efficiency is obviously improved. In addition, an adjustable hood composed of a windshield hinged around the connecting plate automatically adjusts the size of the air inlet under the driving of the hydraulic cylinder, so that the wind can be gathered when the wind speed is weak, the wind energy is improved, and the wind is strong. Avoid the wind, effectively prevent Damage to the components to ensure safe operation.
