Description

旋转开关的操作装置及旋转开关 技术领域
本发明涉及开关技术领域，具体而言，涉及一种旋转开关的操作装置及旋转开关。
背景技术
开关的词语解释为开启和关闭，它是指一个可以使电路开路、使电流中断或使其流到其他电路的元件。最常见的开关是让人操作的机电设备，其中有一个或数个接点。开关的“闭合”表示接点导通，允许电流流过；开关的“开路”表示接点不导通形成开路，不允许电流流过。开关的发展历史从需要人工手动操作的闸刀开关，发展到现在的在各种大型电气控制设备中应用的智能化开关，开关的功能越来越多，安全性也越来越高，旋转式开关作为一种常见的开关，其通过将旋转开关的操作装置锁定在与旋转操作装置的特定状态相应的特定位置来阻止旋转操作装置被未经授权地操作。
随着技术的发展，尤其是在光伏系统中，逐渐出现了对旋转开关远程切换功能的要求，例如在光伏板发生火灾时，需要远程控制将电路断开。通常旋转开关在完成远程切换后需要进行复位操作才能进行后续切换动作，现有技术中为了便于断路器的脱扣器复位，以防止影响断路器的正常分闸，通常需要在分合闸前驱动脱扣器的复位按钮，进而使得复位按钮控制脱扣器复位，然而，如若发生未进行复位操作或者复位操作未成功便驱动旋转开关以控制断路器进行合闸或者分闸操作，将导致自动分合闸功能失效。
发明内容
本发明的目的在于提供一种旋转开关的操作装置及旋转开关，其可以实现脱扣器的可靠复位。

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。此外，术语“第一”、“第二”、“第三”等仅用于区分描述，而不能理解为指示或暗示相对重要性。
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。
在本发明的描述中，还需要说明的是，除非另有明确的规定和限定，术语“设置”、“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。
请参照图1和图9，本实施例提供一种旋转开关的操作装置，该旋转开关的操作装置包括动作件和具有容纳腔21的固定件20，动作件穿设于容纳腔21内；驱动动作件在容纳腔21内运动，动作件可在锁定位与工作位之间切换；锁定位限制动作件转动；动作件处于工作位，脱扣器60可在动作件作用下复位。
其中，需要说明的是，本实施例提供的旋转开关的操作装置不仅具有控制断路器的操作机构动作的功能，同时还具备在控制操作机构动作之前先使得脱扣器60复位的作用。示例地，在本实施例中，上述动作件靠近断路器的一端还可以设有配合部12，从而使得旋转开关的操作装置通过配合部12与断路器的操作机构进行配合，从而实现驱动断路器的分闸或者合闸动作。应理解，旋转开关的操作装置控制断路器的操作机构动作为基础功能，上述旋转开关的操作装置控制断路器的操作机构动作的方式仅 为本实施例的一种示例，并非是对该实现方式的具体限制，本领域技术人员可选择任何可行的实现方式，只要能使得旋转开关的操作装置可以控制操作机构动作以进行分闸或者合闸即可。
在本实施例中，驱动动作件在容纳腔21内运动，动作件可在锁定位与工作位之间切换；锁定位限制动作件转动；动作件处于工作位，脱扣器60可在动作件作用下复位。其中，上述的锁定位可以限制动作件进行转动，而当旋转开关的操作装置自锁定位进入工作位时，则脱扣器60可在动作件的作用下复位，这时动作件同时也解锁了锁定状态，即动作件可以进行转动。因此，本实施例在脱扣器60复位之前可以限制动作件的转动，而在动作件处于工作位使得脱扣器60复位之后，动作件才可以进行转动。
综上所述，本实施例提供了一种旋转开关的操作装置，该旋转开关的操作装置包括动作件和具有容纳腔21的固定件20，动作件穿设于容纳腔21内；驱动动作件在容纳腔21内运动，动作件可在锁定位与工作位之间切换；锁定位限制动作件转动；动作件处于工作位，脱扣器60可在动作件作用下复位。这样一来，当动作件在脱扣器60未复位前由于锁定位的限制而无法进行转动；当动作件脱离锁定位而进入工作位时，则动作件又会作用于脱扣器60而使脱扣器复位。因此，本申请相对于现有技术而言，可以实现在脱扣器60复位后再进行转动以控制断路器分合闸，从而可以使得脱扣器60实现可靠复位，避免了脱扣器60未复位便进行转动操作而导致分合闸失效的问题出现。
本申请可以是在脱扣器60未复位前，通过限制动作件转动的方式以避免脱扣器60未复位便进行转动操作而导致分合闸失效；当然，在本申请的其他实施例中也可以通过在脱扣器60未复位前，通过使得动作件空转的方式来避免脱扣器60未复位便进行转动操作而导致分合闸失效，其中，动作件可以转动但是并不能作用于断路器的操作机构为动作件空转。
其中，上述脱扣器60未复位前通过限制动作件转动的方式，以避免脱扣器60未复位便进行转动操作而导致分合闸失效的方式也包括多种。例如，通过限制动作件的驱动手柄10转动实现、通过限制动作件的抵持件30转动实现、通过固定件的结构限制动作件转动实现等等。
例如，当通过限制抵持件30转动实现时，可以是在脱扣器60复位前限制抵持件30的转动实现。可以包括至少两种实现形式，第一，通过限制抵持件30靠近脱扣器60的一端转动的方式实现(例如可以是当抵持件30靠近脱扣器60的一端只有作用于脱扣器60使脱扣器60复位后才可以不被限制而进行转动)；第二，通过限制抵持件30靠近驱动手柄10的一端转动的方式实现(例如可以是当抵持件30靠近驱动手柄10的一端只有在脱扣器60复位后才可以不被限制而进行转动)。具体实现形式本申请不做限制们只要能够使得脱扣器60在未复位前使旋转开关的操作装置的转动动作被锁定，而在脱扣器60复位后使旋转开关的操作装置的转动动作被解锁即可，具体实现旋转开关的操作装置驱动断路器进行合闸动作卡死的情况多种多样，本申请不再进行一一列举。
下文本实施例将以在脱扣器60复位前通过限制动作件的驱动手柄10转动的形式为例进行举例说明。
上述的动作件包括驱动手柄10和抵持件30，驱动手柄10的转动端穿设于容纳腔21内；抵持件30套设于驱动手柄10的转动端14，推动驱动手柄10沿容纳腔21的轴线运动，驱动手柄10可在锁定位与工作位之间切换，锁定位限制驱动手柄10转动；当驱动手柄10处于工作位，抵持件30作用于断路器的脱扣器60，驱动手柄10可相对于固定件20转动以控制断路器的分闸或合闸。该旋转开关的操作装置可以实现脱扣器60的可靠复位。
上述驱动手柄10用于在固定件20的容纳腔21内转动或者沿容纳腔21的中心轴线运动。当驱动手柄10在固定件20的容纳腔21内转动时，可以控制断路器进行分闸或者合闸。示例地，可以通过在驱动手柄10的 转动端14对应设置配合部12，以使得旋转开关的操作装置通过配合部12与断路器的操作机构进行配合，从而实现断路器的分闸或者合闸动作。例如，该旋转开关的操作装置的配合部12可以是方形孔，对应地，断路器的操作机构可以对应该方形孔设置方轴，从而通过方形孔与方轴的配合以实现旋转开关的操作装置对断路器的控制目的。应理解，上述方形孔和方轴仅为本申请给出的一种示例而已，在其他的实施例中，方形孔和方轴的相对位置可以互换，也可以采用其他的配合结构来实现。
另外，当驱动手柄10沿容纳腔21的中心轴线运动时，驱动手柄10可以控制抵持件30运动，从而使得抵持件30相对固定件20发生移动(此处的移动方向即为沿容纳腔21的轴线方向)。
示例地，在本实施例中，上述抵持件30是套设于驱动手柄10的转动端14的，由于两者之间为套设关系，因此，驱动手柄10与抵持件30之间无径向限制，驱动手柄10可以相对抵持件30进行转动。
在本实施例中，通过推动驱动手柄10，从而使得驱动手柄10沿容纳腔21的轴线运动，如此，可以使得驱动手柄10可在锁定位与工作位之间切换。当驱动手柄10处于锁定位时，驱动手柄10被径向锁止，驱动手柄10可以轴向运动而不能进行径向运动(此处轴向或者径向均以图2或者图3所示方位为主，下同)；当推动驱动手柄10沿容纳腔21的轴线运动时，驱动手柄10可在锁定位与工作位之间进行切换。当驱动手柄10自锁定位进入工作位时，抵持件30便可以作用于断路器的脱扣器60，从而使得抵持件30驱动脱扣器60复位，这时驱动手柄10便可以相对于固定件20转动，进而以控制断路器的分闸或合闸。这样一来，本实施例在驱动手柄10处于锁定位时，驱动手柄10无法转动；只有在驱动手柄10进入工作位之后，此时抵持件30作用于断路器的脱扣器60，进而控制脱扣器60进行复位时，才能使得驱动手柄10相对固定件20转动，进而通过驱动手柄10的转动控制断路器进行分闸或者合闸。如此可有效解决现有技术中脱扣器60未复位便进行操作断路器进行分合闸，从而导致分合闸失效的问题。
综上所述，在使用过程中，可通过推动驱动手柄10沿容纳腔21的轴线方向运动，从而使得驱动手柄10自锁定位进入工作位，从而使得抵持件30在驱动手柄10的带动下作用于断路器的脱扣器60，然后使得脱扣器60复位，进而使得驱动手柄10可以相对固定件20进行转动，从而再以控制断路器的分闸与合闸。如此，本实施例便可以使得旋转开关的操作装置自锁定位进入工作位之后，便可以实现脱扣器60的复位操作，然后再进行驱动手柄10相对固定件20的转动，从而再用于控制断路器进行分闸或者合闸。这样一来，本申请相对于现有技术而言，便可以实现在脱扣器60复位后再进行转动以控制断路器分合闸，从而可以使得脱扣器60实现可靠复位，避免了脱扣器60未复位便进行转动操作而导致分合闸失效的问题出现。
请再结合参照图4和图5，可选地，容纳腔21的内壁上还开设有导向通道23，导向通道23包括第一竖直槽231和与第一竖直槽231连通的第一行程槽232，第一行程槽232与第一竖直槽231呈夹角设置，驱动手柄10的外壁上设有导向件11，导向件11卡设于导向通道23内，其中，当导向件11卡设于第一竖直槽231内，驱动手柄10处于锁定位；当导向件11卡设于第一行程槽232内，驱动手柄10处于工作位。
这样，当导向件11卡设于第一竖直槽231内时，则驱动手柄10处于锁定位，此时驱动手柄10由于导向件11的存在而无法进行转动；当导向件11卡设于第一行程槽232内时，则驱动手柄10处于工作位，此时导向件11可沿第一行程槽232运动，可以使得驱动手柄10相对固定件20转动。应注意，在本实施例中，当导向件11自第一竖直槽231远离第一行程槽232的一端运动至第一竖直槽231和第一行程槽232的交接点时，驱动手柄10带动抵持件30，可以使得抵持件30可以正好作用于脱扣器60(当脱扣器60是通过复位按钮61进行操控复位时，则为复位按钮61，其他描述处同理)。具体地，第一竖直槽231的长度应当根据实际情况合理选择，本申请不再赘述。
需要说明的是，上述的导向通道23的提出即为本申请的一个实施例 而已，在其他的实施例中，也可以采用其他的实现方式以使得驱动手柄10在锁定位和工作位之间切换，以使得驱动手柄10处于工作位，抵持件30作用于断路器的脱扣器60，驱动手柄10可相对于固定件20转动以控制断路器的分闸或合闸。例如，可以也可以将导向件11设置于固定件20上，而将导向通道23设置于驱动手柄10上，具体方式本申请不做限制。
可选地，第一行程槽232与第一竖直槽231呈垂直设置。这样一来，驱动手柄10相对固定件20移动和相对固定件20转动将不会互相干扰，便于操控。
为了使得驱动手柄10在转动之后，能够方便的复位，以避免影响旋转开关的下次工作。在本实施例中，可选地，容纳腔21的内壁上还开设有复位槽24，复位槽24连通于第一竖直槽231与第一行程槽232之间，用于使导向件11复位。
示例地，在一种实施例中，复位槽24包括相互连通的第二竖直槽241和第二行程槽242，第二竖直槽241连通于第一行程槽232与第二行程槽242之间，第二行程槽242连通于第二竖直槽241与第一竖直槽231之间。这样，导向件11可以依次通过第二竖直槽241和第二行程槽242进行复位，从而为下次下压复位按钮61以控制脱扣器60复位做准备。可选地，在本实施例中，上述第一行程槽232与第二行程槽242呈平行设置。
示例地，在另一种实施例中，复位槽24也可以是斜槽，该斜槽的一头连通第一行程槽232远离第一竖直槽231的一端、另一头连通第一竖直槽231远离第一行程槽232的一端。这样，也可以便于驱动手柄10的快速复位。
另外，在本实施例中，为了使得驱动手柄10相对固定件20的转动或者移动能够更加平稳可靠，在本实施例中，上述的导向通道23可以包括两个，两个导向通道23呈对称设置于容纳腔21的内壁上，导向件11也包括两个，两个导向件11呈对称设置于驱动手柄10的外壁上。应理解，每 一组导向件11和导向通道23都应当是适配的。在运动过程中，两个导向件11应当运动方向相同。
可选地，为了便于驱动手柄10的快速复位，固定件20设有自容纳腔21的内壁朝向手柄的方向延伸设置的第一凸块25，转动端14的外壁上设有第二凸块，旋转开关的操作装置还包括弹簧，弹簧套设于转动端14上，且一端与第一凸块25抵接、另一端与第二凸块抵接。此处，应理解，弹簧的设置应当避免对导向通道23造成干扰，具体设置位置本领域技术人员应当根据导向通道23和导向件11的实际设置进行合理选择，本申请不再细述。
请再结合参照图6所示，可选地，驱动手柄10还包括与转动端14连接的手持端13，其中，手持端13用于便于进行人工握持以便于驱动传动端运动。这样，在实际操作过程中，可以方便地对驱动手柄10的转动端14进行操控。
请再结合参照图7和图8，可选地，抵持件30包括环形件31和与环形件31连接的压杆32，环形件31套设于转动端14，固定件20靠近抵持件30的一侧开设有导向槽22，压杆32通过导向槽22延伸至固定件20之外，压杆32用于作用于脱扣器60。这样，抵持件30可以通过压杆32在导向槽22内运动以靠近或者远离固定件20。
为了使得抵持件30相对固定件20移动时能够更加稳定，在本实施例中，可选地，导向槽22包括两个，两个导向槽22分别开设于固定件20上，压杆32包括第一子杆321和第二子杆322，第一子杆321和第二子杆322分别位于环形件31的相对两侧(即第一子杆321和第二子杆322呈对称设置于环形件31的两侧)，第一子杆321和第二子杆322一一对应卡设于两导向槽22内，第二子杆322用于作用于脱扣器60。
可选地，转动端14的外壁上套设有密封圈141，且密封圈141位于手持端13与抵持件30之间。另外，转动端14的外壁上还可以套设有垫片， 且垫片位于密封圈141远离抵持件30的一侧。这样可便于实现旋转开关的操作装置相对机柜(机柜可用于固定旋转开关操作装置)的密封。
另外，为了便于旋转开关的操作装置相对机柜的固定，在本实施例中，该旋转开关的操作装置还可以包括螺母40，对应地，固定件20的外壁上还可以设置于与螺母40匹配的螺纹，这样，旋转开关的操作装置便可以通过螺母40被安装于机柜上。
在本实施例中，驱动手柄10是可以驱动抵持件30相对固定件20移动的，且驱动手柄10是可以相对抵持件30进行转动的，因此，抵持件30与固定件20之间具有轴向约束而无径向约束。为此，可选地，转动端14还可以包括挡圈50和阻挡部142，阻挡部142和挡圈50分别设于环形件31的相对两侧，以用于限位环形件31相对驱动手柄10的转动端14发生轴向运动。
本发明的另一方面，请结合参照图9和图10，本实施例还提供了一种旋转开关，该旋转开关包括脱扣器60和上述的旋转开关的操作装置，旋转开关的操作装置用于作用于脱扣器60，以使脱扣器60复位。该旋转开关可以实现脱扣器60的可靠复位。由于上述的旋转开关的操作装置的结构及其有益效果均已在前文做了详细阐述，故在此不再赘述。
需要说明的是，上述脱扣器60还可以包括复位按钮61，其中，复位按钮61用于使脱扣器60复位，这样，本实施例只要通过旋转开关的操作装置作用于复位按钮61便可以实现控制脱扣器60的复位。
以上所述仅为本发明的可选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特 征，在不矛盾的情况下，可以通过任何合适的方式进行组合，为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。
