具体实施方式
下面详细描述本发明的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本发明，而不能理解为对本发明的限制。
在本发明的描述中，需要理解的是，涉及到方位描述，例如上、下、前、后、左、右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，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。
本发明的描述中，除非另有明确的限定，设置、安装、连接等词语应做广义 理解，所属技术领域技术人员可以结合技术方案的具体内容合理确定上述词语在本发明中的具体含义。
参考图1、图2、图3所示，为本技术方案根据本发明第一方面实施例的一种低压电缆旁路转电应急抢修车，包括：车体100；支撑架200，设置于所述车体100上且所述支撑架200具有一可转动的中心轴210；三组转盘300，三组所述转盘300通过依次穿设于中心轴210上以装配于所述支撑架200，三组所述转盘300可适用于三相电缆同时故障的应急抢修；每组所述转盘300的四周皆设置有多个等间距环形布置的电缆盘310，本实施例中优选为4个；转盘驱动机构400，采用电机减速器，与所述中心轴210一端连接以驱动所述转盘300转动，便于更换具体哪个电缆盘工作；电缆盘驱动机构500，与所述电缆盘310摩擦转动以展放和回收电缆；电缆盘检测模块600，用于检测所述电缆盘310与电缆盘驱动机构500的相对位置，本实施例中优选位置传感器，也可采用其他已知的检测模块如图像传感器等；控制器700，分别与所述转盘驱动机构400、电缆盘驱动机构500、电缆盘检测模块600电性连接。
使用时，先将低压电缆旁路转电应急抢修车行驶到故障发生地，打开车厢，先选择单相展放还是三相展放，之后则利用电缆盘检测模块600检测所述电缆盘310与电缆盘驱动机构500的相对位置并反馈给控制器700，如果所选择的电缆盘310与电缆盘驱动机构500没有接触不能摩擦转动，则控制器700根据相对位置信号启动转盘驱动机构400，转盘驱动机构400通过中心轴210带动转盘300旋转至电缆盘310与电缆盘驱动机构500接触的位置，然后再控制电缆盘驱动机构500启动，使得电缆盘可以开始展放电缆。
根据本发明第一方面实施例的低压电缆旁路转电应急抢修车，采用同轴多组多盘的结构，能够容纳电缆的数量更多且适用于单相或三相同时展放与回收，配置电缆盘检测模块、转盘驱动机构与电缆盘驱动机构配合，可根据故障情况与转盘的实时状态及时选择相应的电缆盘，作业效率大大提高，并适用于35kV及以下电压等级使用场合；设备高度集成，其灵活性强。
由于单相展放时只需要使用一组转盘300，如果中心轴210每次转动都同步带动三组转盘300同时转动，则会浪费很多电能，且不利于后期其他转盘的同步展放，在本发明第一方面的一些实施例中，每组所述转盘300与所述中心轴210之间分别通过一离合器连接，所述离合器与所述控制器700电性连接，控制器700可以根据实际需要选择哪一组转盘的电缆盘工作，通过设置离合器，可实现转盘单个转动或三组转盘同步转动。
利用图3并结合图4所示，在本发明第一方面的一些实施例中，所述电缆盘驱动机构500包括第一电机510，以及三组支架520、轴承530、驱动轴540、摩擦轮550，所述第一电机510通过链条或皮带560与第一组的驱动轴540传动连接，所述轴承530安装于所述支架520并用于装配所述驱动轴540，所述摩擦轮550设置于所述驱动轴540上并与所述电缆盘310摩擦转动，三组所述驱动轴540之间通过连杆570连接。
在本发明第一方面的一些实施例中，所述驱动轴540与连杆570之间通过轴叉580连接，轴叉580与连杆570通过键连接，从而便于拆卸与维护。
在本发明第一方面的一些实施例中，所述支架520分为上支架521和与支架521铰接的下支架522，所述轴承530位于所述上支架521，所述上支架521和下支架522之间连接有弹簧机构523和可伸缩支撑杆524。可伸缩支撑杆524保证上支架521上的摩擦轮550具有特定的高度，又可由弹簧机构523提供缓冲力和恢复力，便于本盘电缆展放完成，需要进行下一个电缆盘展放时，通过整个转盘300的转动，展放完成的电缆盘通过在摩擦轮550处设置的弹簧机构523将空电缆盘越过摩擦轮550。
在本发明第一方面的一些实施例中，所述转盘300与所述支撑架200之间设置有可拆卸的卡盘机构800。本实施例中卡盘机构800采用顶紧限位销，在本电缆盘310不展放电缆时，通过顶紧限位销将本电缆盘310进行锁紧，防止在转动的时候电缆盘自行转动。
在本发明第一方面的一些实施例中，所述车体100包括车辆底盘110、车 厢120，所述车厢120分为工具室121和电缆盘室122，所述支撑架200、转盘驱动机构400、电缆盘驱动机构500、电缆盘检测模块600、控制器700位于所述电缆盘室122内。旁路电缆及工具合理置入低压电缆旁路转电应急抢修车，利用低压电缆旁路转电应急抢修车存储、运输、展放旁路电缆，解决搬运、展放的繁杂工作量，减少绝缘损耗，消除安全隐患。同时电缆盘310的电缆端头提前处理好，现场节省较多时间，只需电缆与电缆相互对接即可完成电缆的连接。
在本发明第一方面的一些实施例中，所述车辆底盘110下方设置有多只液压支腿130，多只所述液压支腿130用于在伸出时将所述车辆底盘110、车厢120顶起悬空。本实施例中配有四只液压支腿130，分别安装固定在车体的大梁上，每只支腿可独立承载6T。支腿使用时，通过支腿油缸的伸出，使支撑脚向下支撑触地，将车身顶起，使车辆的大部分重量由支腿支撑，从而保持车体的平稳，减轻车辆弹簧钢板的负载。使用完毕后，通过支腿油缸的收缩使支撑脚向上收缩，并离地有足够的高度，以确保不影响行车及设备的安全。
根据本发明第二方面实施例的一种基于所述低压电缆旁路转电应急抢修车的应急抢修方法，包括以下步骤：根据现场故障情况选择单相应急抢修或三相应急抢修，其中单相应急抢修使用一个电缆盘展放，三相应急抢修从三组转盘中各选择一个电缆盘展放；检测所选择的待展放电缆盘与电缆盘驱动机构的相对位置；根据所检测的相对位置信号驱动转盘旋转，使所选择的待展放电缆盘与电缆盘驱动机构处于可摩擦传动位置；控制电缆盘驱动机构启动，使待展放电缆盘与电缆盘驱动机构摩擦传动，从而实现电缆展放；将展放的旁路电缆与转接电缆连接实现旁路转电，抢修完成后回收电缆至电缆盘。
采用同轴多组多盘的结构，能够容纳电缆的数量更多且适用于单相或三相同时展放与回收，配置电缆盘检测模块、转盘驱动机构与电缆盘驱动机构配合，可根据故障情况与转盘的实时状态及时选择相应的电缆盘，作业效率大大提高，并适用于35kV及以下电压等级使用场合；设备高度集成，其灵活性强。
由多个位置传感器、逻辑可编程控制器、无线遥控、电磁阀组和相应的液 压执行机构组成的智能化电液控制系统，通过多个位置传感器来检测卷盘机构各个动作的状态并输入到逻辑可编程控制器中，使之与预置于逻辑可编程控制器中用程序语言编写各个动作状态逻辑关系比较，判断实际动作是否达到预设的状态，预设状态达到后，逻辑可编程控制器输出控制指令，控制电液控制阀动作进而控制相应液压控制元件的动作，实现预置控制功能。
当出现突发状态时，程序运行到一半就中断时，再次运行程序时，系统会进行自检，如果各传感器反馈回的信号判定此时线盘不在预设零点位时，系统会运行复位程序，使线盘回到预设零点位，然后等待下一步指令。
在本发明第二方面的一些实施例中，单相应急抢修时，对应转盘的离合器与中心轴闭合连接，三相应急抢修时三组转盘的离合器与中心轴闭合连接。
在本发明第二方面的一些实施例中，所述旁路电缆320与转接电缆330之间的连接采用可分离连接器；所述可分离连接器的母头采用带塞止头311的C型前接头312，公头采用C接口双通头313；所述可分离连接器与所述旁路电缆320的配置方案分为两种规格：①、电缆两端均安装C型前接头312和塞止头311；②、电缆一端安装C型前接头312和塞止头311，另一端安装C型前接头312、塞止头311和双通头313；所述可分离连接器与所述转接电缆330的配置方案分为三种规格：①、电缆一端安装C型前接头312、塞止头311和双通头313，另一端安装户外终端；②、电缆一端安装C型前接头312、塞止头311和双通头313，另一端安装E型前接头312和塞止头311；③、电缆一端安装C型前接头312、塞止头311和双通头313，另一端安装内锥插拔式GIS终端。
如图5所示，基于上述配置方案可实现四种接口对接：①多根旁路电缆320依次对接，可实现与配电柜中的欧式肘形头连接；②旁路电缆320连接带户外终端的转接电缆330，可实现与户外架空线或户内母排340连接；③旁路电缆320连接带E型前接头312和塞止头311的转接电缆330，可实现与配电柜中的美式肘形头340连接；④旁路电缆320连接带内锥插拔式GIS终端350的转接电缆330，可实现与GIS开关柜的连接。从而实现不同线路的连接，以及实现电缆与 电缆间的快速连接，使用完成后能够快速分离。
