具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。通常在此处附图中描述和示出的本发明实施例的组件可以以各种不同的配置来布置和设计。
因此，以下对在附图中提供的本发明的实施例的详细描述并非旨在限制要求保护的本发明的范围，而是仅仅表示本发明的选定实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。
在本发明的描述中，需要说明的是，术语“中心”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系，或者是该发明产品使用时惯常摆放的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
需要说明的是，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
此外，术语“水平”、“竖直”等术语并不表示要求部件绝对水平或悬垂，而是可以稍微倾斜。如“水平”仅仅是指其方向相对“竖直”而言更加水平，并不是表示该结构一定要完全水平，而是可以稍微倾斜。

工作原理：需要进行油样采集时，首先通过远程遥控智能移动组件2移动到指定的位置区域，紧接着，驱动机械手本体3到油样瓶的位置，通过机械手爪单元4抓取油样瓶，驱动机械手本体3移动到辅助取油样管道件502的出油口下方，并放置油样瓶；
驱动机械手本体3移动到阀门开闭工装的位置，通过机械手爪单元4抓取阀门开闭工装并固定，通过机械手爪单元4上的视觉摄像头确定油管开闭阀门53和辅助阀门501的位置，机械手本体3驱动机械手爪单元4通过阀门开闭工装带动阀门旋转，依次打开油管开闭阀门53和辅助阀门501，油样瓶进行油样采集；
油样采集完成后，机械手本体3驱动机械手爪单元4通过阀门开闭工装带动阀门向相反的旋转，依次关闭辅助阀门501和油管开闭阀门53，机械手爪单元4将阀门开闭工装放置到指定位置，机械手爪单元4抓取完成油样采集的油样瓶，将油样瓶放置到指定位置，机器人完成本次油样采集作业。
本方案提供的变电站油样采集机器人通过机械手、取油样辅助组件和辅助取油样工装有利于取油样高效化和自动化，而且辅助取油样工装结构巧妙、维修方便，大大提高了取油样的经济效益。

1、如图15、18、19所示，取油样机器人在被远程控制移动到取油样的位置后，通过机械手爪单元4抓取采集油样瓶102，将其放置在采集油样瓶放置台505上。
2、如图16、17、20、21所示，放置好采集油样瓶102后，机械手抓单元4抓取大阀门开闭工装106，机械手爪单元4中视觉摄像头识别并确认油管开闭阀门53的位置和状态，机械手本体3移动至油管开闭阀门53位置，将大阀门开闭工装106的固定柱702插入油管开闭阀门53的孔隙中，驱动机械手爪单元4带动油管开闭阀门53旋转，实现油管开闭阀门53的打开；和打开油管开闭阀门53相同的方法，利用小阀门开闭工装103打开辅助阀门501,采集油样瓶102开始收集油样。
3、图22为本发明提供的机械手抓取完成油样收集后的采集油样瓶的状态示意图；图23为本发明提供的将采集油样瓶中收集的油样倒入清洗油样瓶的状态示意图。如图所示，油样收集完成后，驱动小阀门开闭工装103关闭辅助阀门501；将采集油样瓶102收集的油样倒入清洗油样瓶101中，再将采集油样瓶102放置到采集油样瓶放置台505上，重复第2步。
4、采集油样瓶102收集完成后，驱动小阀门开闭工装103关闭辅助阀门501，辅助阀门501关闭后，将小阀门开闭工装103放置在小阀门开闭工装放置台104上，机械手爪单元4抓取采集油样瓶102放置到工装放置台107的指定位置上，机械手恢复至初始状态，远程控制取油样机器人返回，完成整个取油样任务。
