Description
本发明涉及移动通信电调天线技术领域，尤其涉及一种角度指示器及电调天线下倾角指示装置。
在移动通信工程中，基站天线作为接收和发射电磁波的重要设备，对通信信号的覆盖质量有重要影响。在基站站点设计确定后，信号覆盖的范围和覆盖质量与天线下倾角密切相关，而准确调节天线下倾角是优化网络覆盖质量的重要措施。
通常，有两种调整天线下倾角的方法，一种是调整天线的机械下倾角，即通过调节天线安装支架的角臂夹角来改变天线的下倾角度，此法的缺点是需要人工上塔操作，不仅操作费时费力，且天线背瓣可能产生邻区干扰，影响通话质量。因此，现阶段大部分基站天线都采用电调下倾角方式，即通过调整天线移相器以改变相位，使天线水平电子波束方向产生变化，以达到调节天线覆盖范围的目的，该法可以通过远程电调遥控的方式进行操作，不需要人工上塔，省时省力，操作方便。
然而，电子波束方向指向(即电下倾角)人们是不能直观看到的，这会给生产及工程施工带来不便，因此，需要通过与移相器传动装置相关联的指示装置将天线的电下倾角直观地显示出来。
在现有技术中，一种方法是通过一根伸出至端盖外的标尺杆来指示天线电下倾角度，标尺杆在天线内的一端与移相器传动装置连接，标尺杆是刚性的，伸出天线罩体外很长，不仅自身较易受到外部环境的破坏，杆体及穿过的孔口在严寒地区还可能产生冰冻而卡死标尺杆，导致天线不能正常工作，而且在工程施工中很长的标尺杆也会影响射频连接头的防水作业。还有一种方法是采用齿轮减速机构带动的刻度盘，其结构较为复杂，另外，对于内置 电机形式的电调天线来说内部结构布局也会受到很大制约，不利于天线结构的小型化。
发明内容

进一步，第一运动组件和第二运动组件的外部设置有保护壳体。
一种电调天线下倾角指示装置，其中，包括：推拉杆，推拉杆与传动机 构相连，传动机构在驱动移相器运动时可带动推拉杆移动；转动件，转动件上设置有角度指针，转动件与推拉杆相连，推拉杆移动时可带动转动件旋转；刻度盘，刻度盘上设置有角度标识，刻度盘与转动件相对设置，通过转动件上的角度指针指向的刻度盘上的角度标识可显示出电调天线下倾角。
进一步，包括保护套筒，推拉杆和转动件活动设置在保护套筒中，推拉杆在传动机构的带动下可在保护套筒中移动，转动件在推拉杆的带动下可在保护套筒中旋转。
进一步，保护套筒内部设置有导向轨道，推拉杆在传动机构的带动下可在保护套筒中沿导向轨道移动并带动转动件旋转。
进一步，转动件的内部形成有导向空间，推拉杆活动设置在转动件内部的导向空间中，推拉杆在传动机构的带动下可在导向空间中移动并带动转动件旋转。
进一步，推拉杆上设置有连接柱，转动件上设置有螺旋槽，连接柱活动设置在螺旋槽中，推拉杆移动时，连接柱可在螺旋槽中滑动，以驱动转动件旋转。
进一步，螺旋槽环绕设置在转动件的壁面上，且螺旋槽的两个端部在转动件的轴向上不发生重叠。
本发明的角度指示器及电调天线下倾角指示装置的优点在于：

2)本发明中采用推拉杆与移相器传动机构连接，并通过转轴将传动机构的直线运动转换为转轴的旋转运动，从而将天线下倾角由直线刻度标尺指示转化圆周刻度盘指示，克服了现有技术中标尺杆伸出天线外壳很长的长度，占用较大的天线端盖空间，影响天线安装施工和接口处防水施工的问题。

图7为本发明的第二实施例中的刻度盘的结构示意图。
为了更好的了解本发明的目的、结构及功能，下面结合附图，对本发明的一种角度指示器及电调天线下倾角指示装置做进一步详细的描述。
本发明的角度指示器可用来显示目标物的调节角度，例如，当对不容易观察到的组件进行角度调整时或组件的调整角度无法直观地显示时，可通过本发明的角度指示器来直观容易地观测调整后的角度。
进一步，本发明的角度指示器包括第一运动组件、第二运动组件和角度指示盘。其中，第一运动组件与目标物的驱动组件相连，驱动组件在驱动目标物移动以进行角度调整时，可同步带动第一运动组件移动。应注意的是，驱动组件的驱动方式可以是多种形式的，如直线驱动、曲线驱动等，但最常见的方式为直线驱动，也即驱动组件在驱动目标物移动时会带动第一运动组件做直线运动，当然，如果驱动组件的驱动方式为非直线驱动时，也可以通过设置中间传动件，以将驱动组件的非直线驱动转换为第一运动组件的直线运动。
进一步，第二运动组件与第一运动组件相连，以承接第一运动组件的运动。其中，第一运动组件上设置有第一连接结构，第二运动组件上设置有第二连接结构，第一连接结构与第二连接结构相连，第一运动组件移动时可通过第一连接结构与第二连接结构带动第二运动组件做旋转运动。应注意的是，第一连接结构和第二连接结构可为现有将直线运动转换为旋转运动的所有结构形式，例如柱体与螺旋槽、螺旋杆与卡槽等，当然，如果第一运动组 件为非直线运动，则第一连接结构和第二连接结构应选用将相应的非直线运动转换成旋转运动的结构，也即，第一连接结构和第二连接结构的基本作用就是承接第一运动组件的驱动并将其转换成第二运动组件的旋转运动。
进一步，角度指示盘相对于第二运动组件设置，用来标识角度。其中，第二运动组件上设置有角度指示针，目标物的驱动组件在驱动目标物移动时会同步带动第一运动组件移动，第一运动组件移动时又会同步带动第二运动组件旋转，由此，第二运动组件的旋转便可通过角度指示针在角度指示盘上的相对位置来体现，也即可直观地显示出目标物的调节角度。
进一步，基于整体设备的小型化需求，应尽量减小角度指示器等此类辅助设备的尺寸和占用空间。由此，本发明的角度指示器中可将第一运动组件和第二运动组件的运动路径进行适当叠加，例如，将第一运动组件设置在第二运动组件的外部，当目标物的驱动组件带动第一运动组件移动时，第一运动组件可逐渐与第二运动组件在轴向上进行重叠并带动第二运动组件旋转；或直接将第一运动组件设置在第二运动组件的内部，目标物的驱动组件可带动第一运动组件在第二运动组件的内部移动并带动第二运动组件旋转。
进一步，本发明的角度指示器的应用场景非常广泛，有可能会是室外或环境恶劣的地区，为保证角度指示器的长久使用，优选的是，本发明的角度指示器设置有保护外壳，第一运动组件和第二运动组件可设置在保护壳体的内部，由于角度指示盘需要经常被用来观测数据，故通常会设置在保护壳体的外部，如设置在保护壳体上与第二运动组件上的角度指示针相对应的端部。
如图1至图4所示，其为本发明的电调天线下倾角指示装置1的第一实施例。本实施例中，电调天线下倾角指示装置100包括套筒110，套筒110内部形成有第一容纳腔室111和第二容纳腔室112，第一容纳腔室111中活动设置有推拉杆120，第二容纳腔室112中活动设置有转轴130。
进一步，推拉杆120为杆状结构，可在套筒110的第一容纳腔室111中做直线运动。其中，推拉杆120的一端形成有连接槽121，连接槽121可与 传动机构2相连，传动机构2可用于驱动移相器运动，以实现对天线波束电下倾角度的调节，同时，在传动机构2的带动下，推拉杆120可在套筒110内部的第一容纳腔室111中往复移动；推拉杆120的另一端设置有柱销122，本实施例中，对应于推拉杆120与转轴130的位置关系，柱销122设置在推拉杆120的下端面上。
进一步，转轴130为柱状结构，可在套筒110的第二容纳腔室112中做旋转运动。其中，转轴130的一端设置有卡槽131，卡槽131中可卡设有卡环132，以防止转轴130在套筒110的第二容纳腔室112中轴向运动；转轴130的另一端设置有指针133，指针133可随转轴130同步旋转；转轴130的侧壁面上形成有螺旋槽134，螺旋槽134在转轴130的两个端部之间环绕延伸设置，且螺旋槽134的两个端部在转轴130的轴向上不发生重叠。
进一步，套筒110内部的第一容纳腔室111和第二容纳腔室112之间形成有连接槽，推拉杆120上的柱销122可穿过连接槽后与转轴130上的螺旋槽134相连，由此，传动机构2带动推拉杆120在套筒110内部的第一容纳腔室111中移动时，推拉杆120上的柱销122可沿转轴130上的螺旋槽134滑动，并同步驱动转轴130旋转。应注意的是，由于转轴130上的螺旋槽134的结构设计，推拉杆120对转轴130的驱动旋转不会超过360度，以保证本发明的电调天线下倾角指示装置100的准确性及安全性。
进一步，套筒110上对应于转轴130上的指针133的端部设置有刻度盘140，刻度盘140上可设置有下倾角度指示刻线和角度指示数字。其中，刻度盘140通过卡爪141设置在套筒110端部的安装孔113内，转轴130上的指针133对应于刻度盘140上的下倾角度指示刻线和角度指示数字，当指针133随转轴130转动时，指针133便会相对于刻度盘140转动，此时指针133所指示的角度即为天线当前电下倾角。应注意的是，刻度盘140优选为透明材料制成，以便透过刻度盘140可以观看到指针133位置，同时，刻度盘140上的刻度及角度数字可以刻印在刻度盘140上，也可以采用刻度标签粘贴。
进一步，套筒110上设置有支撑座114，本发明的电调天线下倾角指示 装置100可通过支撑座114固定在天线反射板上，具体来说，可安装于天线底部端盖处，并且刻度盘140应露出至天线外壳外，以便从天线外就可以看到刻度盘140上的角度指示。
如图1、图5至图7所示，其为本发明的电调天线下倾角指示装置1的第二实施例。本实施例中，电调天线下倾角指示装置200包括相对设置的第一轴套210和第二轴套250，螺旋管230活动设置在第一轴套210和第二轴套250上。
进一步，螺旋管230为柱状结构，可相对于第一轴套210和第二轴套250做旋转运动。其中，螺旋管230一端设置有指针233，指针233可随螺旋管230同步旋转；螺旋管230的另一端形成有开口，内部形成有容置空腔，且容置空腔的内侧壁上形成有螺旋槽234，螺旋槽234在容置空腔的两个端部之间环绕延伸设置，且螺旋槽234的两个端部在容置空腔的轴向上不发生重叠。应注意的是，第一轴套210和第二轴套250上设置有轴向止挡，螺旋管230与轴向止挡相接触，以限制螺旋管230产生轴向运动。
进一步，推拉杆220为杆状结构，活动设置在螺旋管230内部的容置空腔中，可在容置空腔中做直线运动。其中，推拉杆220的一端形成有连接槽221，连接槽221可与传动机构2相连，传动机构2可用于驱动移相器运动，以实现对天线波束电下倾角度的调节，同时，在传动机构2的带动下，推拉杆220可在螺旋管230内部的容置空腔中往复移动；推拉杆220的另一端设置有柱销222，推拉杆220插接到螺旋管230内部的容置空腔后，柱销222可与螺旋管230上的螺旋槽234相连，由此，传动机构2带动推拉杆220在螺旋管230内部的容置空腔中移动时，推拉杆220上的柱销222可沿螺旋管230上的螺旋槽234滑动，并同步驱动螺旋管230旋转。应注意的是，由于螺旋管230上的螺旋槽234的结构设计，推拉杆220对螺旋管230的驱动旋转不会超过360度，以保证本发明的电调天线下倾角指示装置200的准确性及安全性。
进一步，第一轴套210上对应于螺旋管230上的指针233的位置处设置 有刻度盘240，刻度盘240上可设置有下倾角度指示刻线和角度指示数字，当指针233随螺旋管230转动时，指针233便会相对于刻度盘240转动，此时指针233所指示的角度即为天线当前电下倾角。
进一步，第一轴套210和第二轴套250上设置有安装座260，通过安装座260可将本发明的电调天线下倾角指示装置200固定安装在天线反射板上。
本发明的电调天线下倾角指示装置结构紧凑，占用空间小，有利于天线内部的结构布局，且有外壳保护免受恶劣环境影响，克服了现有技术的不足。
以上借助具体实施例对本发明做了进一步描述，但是应该理解的是，这里具体的描述，不应理解为对本发明的实质和范围的限定，本领域内的普通技术人员在阅读本说明书后对上述实施例做出的各种修改，都属于本发明所保护的范围。
