Abstract

本发明涉及一种用于风力涡轮机的舱门止动件，具体地说，涉及一种用于具有带有舱门(22)的壳体(6，7)的风力涡轮机(2)的舱门止动件(30)，其包括布置在舱门(22)的外表面和壳体(6，7)的外表面之间的第一叉股(32)。

Description

用于风力涡轮机的舱门止动件
技术领域
本文所描述的主题大致涉及例如关闭物止挡件(closurecheck)等的各种各样的构件，并且更具体地，涉及用于风力涡轮机舱门(hatch)的止动件(stop)。
背景技术
风力涡轮机是一种用于将风的动能转换为机械能的机械。如果机械能直接由机器所使用，例如用于抽水或用于磨小麦，则该风力涡轮机可称为风车(windmill)。类似地，如果机械能被转换为电，则该机械也可称为风力发电机(wind generator)或风力发电站(wind powerplant)。
风力涡轮机典型地根据叶片绕其旋转的垂直的或水平的轴线而分类。一种所谓的水平轴线式风力发电机示意性地示出在图1中且可从通用电气公司获得。这种用于风力涡轮机2的特定构造包括支撑着包围传动系统(drive train)8的外罩(nacelle)6的塔筒(tower)4。叶片10布置在轮毂上以便在外罩6外、在传动系统8的一端处形成“转子”。旋转的叶片10驱动连接至连同接收来自风速计18的输入的控制系统16一起、布置在外罩6内的传动系统8的另一端处的发电机14的齿轮箱(gearbox)12。
如图2中所示，风力涡轮机2的各种壳体(enclosure)，例如外罩壳体6、毂锥(hub cone)壳体7和/或其它壳体，典型地设有用于允许至到风力涡轮机2内部的进入的舱口(hatchway)20。该舱口20典型地由门或舱门22所遮盖，其通过一侧上的一个或多个铰链24和另一侧上的闩锁(latch)26而连接至壳体。在常规的保养和故障检修期间，开启的舱门未经固定地(unsecured)靠在风力涡轮机2的壳体的外表面(external surface)上。但是，在与风力涡轮机相关联的强风环境中，这样的未经固定的敞开的舱门22可被风吹以致以高速关闭、撞击可能出现于舱口20中的任何人员和/或设备。因此，有时利用螺纹C形夹(screwed C-clamp)来固定(secure)舱门22，该螺纹C形夹将敞开的舱门22的内表面(internal surface)压向壳体的外表面。
发明内容
与这样的传统手段相关联的这些和其它缺陷在本文中通过在各种实施例中提供用于具有带有舱门的壳体的风力涡轮机的舱门止动件而加以解决，该舱门止动件包括布置在舱门的外表面和壳体的外表面之间的第一叉股(prong)。
附图说明
现在将参考下文的附图(“图”)来描述本技术的各个方面，这些附图不一定按比例绘制，但是遍及几个视图中的每一个均使用相同的参考标号以表示相应的部件。
图1是传统的风力发电机的示意性侧视图。
图2是用于图1中所示风力发电机的传统的舱口的正视图。
图3是用于风力涡轮机的舱门止动件的正视图。
图4是在图2的舱口中的图3的舱门止动件的正视图。部件列表：2    风力涡轮机4    塔筒6    外罩7    毂锥8    传动系统10   叶片12  齿轮箱14  发电机16  控制系统18  风速计20  舱口22  舱门24  铰链26  闩锁30  舱门止动件32  第一叉股34  第二叉股36  第三叉股
具体实施方式
图3是舱门止动件30的正视图。在本文所示的示例中，舱门止动件30成E形，带有彼此连接的第一叉股32、第二叉股34和第三叉股36。E形同样包括两个由叉股32至36中的任何两个及其间的连接部所形成的成U形的、成C形的，或成V形的部分。叉股32至36中的一个或多个可比其它的短些。例如，舱门止动件30同样可为成F形的，带有较短的第二叉股32和/或不带第三叉股36。
如图4中所示，当舱口20完全敞开时，舱门止动件30的一部分布置在舱门22的外表面和毂锥壳体7的外表面之间。尤其地，第一叉股32被楔入(wedge)舱门22的外部表面和毂锥7的外部表面之间。另外的叉股34和36则提供支撑结构以用于将舱门止动件30保持就位(keep in place)。但是，同样可以其它方式(例如利用可移除的紧固件和/或粘合剂)来固定舱门止动件30。虽然叉股32至36之间的连接部在此显示成由与叉股本身一样的刚性材料所制成，但是同样可使用其它的刚性的和/或柔性的材料。
在本文所示的示例中，第一叉股32在舱门22的外表面和毂锥壳体7的外表面之间延伸。第二叉股34连接到第一叉股32上且布置成支靠着(against)舱门22的内表面。第三叉股36同样连接至第一叉股32和第二叉股34且布置成支靠着毂锥壳体7的内表面。但是，各个叉股32至36可以带有或不带有其它叉股的各种其它的构造和顺序而布置。例如，第一叉股32可布置成支靠着毂锥壳体7的内表面，并且，第二叉股34可布置成顶靠着舱门22的内表面。舱口止动件30可类似地连同在风力涡轮机2的其它区域(例如外罩6)中的舱口20一起被使用。
上文所描述的舱门止动件30提供了优于传统的螺纹C形夹的各种优点。例如，舱门止动件30可更容易且更快地被安装和移除。舱门止动件30还较不易于出现操作者错误，因为其不需要被拧成与毂锥壳体7和/或舱门22的表面相接合。
应强调的是，上文所描述的实施例、且尤其是任何“优选的”实施例，仅是在此所阐述的用于提供对本技术各方面的清楚的理解的各种实施方式的示例。本领域的普通技术人员将能够改变这些实施例中的许多实施例而不会在实质上背离变完全由所附权利要求的合理解释所限定的保护范围。
