Description

一种抱杆电源 技术领域
本发明涉及电源技术领域，尤其涉及一种抱杆电源。
背景技术
现如今，随着4G/5G的逐渐普及和商用，以及物联网、自动驾驶等网络技术的发展，用以给射频发射器、摄像头、信号灯等供电的抱杆式二次电源(简称抱杆电源)需求十分旺盛。在室外环境中，现有抱杆电源通常设计成方形，并安装在支撑杆(如电线杆)侧面，如图1所示，抱杆电源包括方形的电源箱以及布置在电源箱中的电芯等部件，通过连接件安装后悬挂在支撑杆侧面。然而，由于抱杆电源一般较重，所以这种设计和安装方式存在重心不稳、迎风面积大等缺点，特别是在恶劣天气下，抱杆电源存在跌落风险，稳固性较差；另外，在这种方形抱杆电源的电源箱中，电芯的布置通常都借鉴传统电芯布置方式，也就是多组电芯并行使用，多组电芯通过层叠紧密排布的形式布置在一起。然而，这种布置方式中电芯间散热不均匀，电芯间温度差异大，在电池充放电过程中容易造成局部过热，降低了局部电芯的性能和使用寿命下降，局部过热甚至还容易导致安全隐患问题。
发明内容
本发明实施例提供一种抱杆电源，能够提高抱杆电源的稳固性，同时避免抱杆电源中电芯间散热不一致而导致局部过热问题，延长抱杆电源的使用寿命。
第一方面，本发明实施例提供了一种抱杆电源，所述抱杆电源包括待安装到支撑杆的圆环状箱体；所述圆环状箱体的中心具有一个圆柱形空腔，所述圆柱形空腔用于环抱所述支撑杆；所述圆环状箱体中均匀设置有多个电芯；当所述抱杆电源安装在所述支撑杆时，所述抱杆电源的重心位于所述支撑杆的横截面。具体的，在所述圆环状箱体中，所述多个电芯的重心围绕所述圆柱形空腔的中心线均匀分布。这样，当抱杆电源安装在支撑杆上时，所述抱杆电源的重心(F)就位于所述支撑杆的横截面上，在可能的实施例中，所述抱杆电源的重心甚至能位于所述支撑杆的横截面的中心。其中，所述横截面位于所述支撑杆的内部，且所述横截面与所述圆柱形空腔的中心线垂直。
可以看出，本发明实施例中，通过将抱杆电源设计成中心具有一个圆柱形空腔的圆环状箱体，可使得抱杆电源安装到支撑杆后环抱所述支撑杆，又由于所述抱杆电源的多个电芯在所述圆环状箱体中均匀布置，所以可使得所述抱杆电源的重心位于所述支撑杆的横截面(甚至中心)上。因此，实施本发明实施例能够提高抱杆电源的稳固性，另外，由于电芯之间均匀分布，所以每个电芯的周围环境基本一致，所以每个电芯的散热情况也会基本一致，避免电芯间散热不一致而导致局部过热问题，延长抱杆电源的使用寿命。
本发明实施方式中，所述圆环状箱体分为两个半圆环柱状结构体，所述两个半圆环柱状结构体的第一交界处设置有活动铰链，所述两个半圆环柱状结构体通过所述活动铰链进行可活动连接。所述两个半圆环柱状结构体的第二交界处设置有可调式紧固结构；当所述两个半圆环柱状结构体通过所述活动铰链闭合成所述圆环状箱体时，所述可调式紧固结构 用于锁紧所述圆环状箱体。
本发明实施例，所述圆环状箱体中均匀设置有多个电芯，具体为：所述圆环状箱体中，所述多个电芯的重心围绕所述圆柱形空腔的中心线均匀分布。具体的，在圆环状箱体的内部空间中多个电芯具有多种多样的布置方式。
在一种可能的布置方式中，圆环状箱体的内部空间中布置有多个方形电芯或软包电芯(例如16个方形电芯)，每个电芯均具有电芯极耳，所述电芯极耳在电芯表面向上布置，不同电芯之间的电芯极耳的汇流排采用软连接(如电线连接)或者硬连接(如铜片连接)。这些电芯的重心围绕圆环状箱体的圆柱形空腔的中心线均匀分布，具体的，这些电芯在内部空间中环绕所述圆柱形空腔的中心线呈径向放射状分布。每个电芯的最大横截面均与所述圆柱形空腔的中心线共面。相邻电芯各自的最大横截面之间的夹角为为22.5°，这些夹角之和为360°。在可能的实施例中，可根据实际用电的需求，设计n层的抱杆电源，这时，可以理解的，所有抱杆电源的夹角7之和为360°的n倍，n为大于或等于1的整数。
在又一种可能的布置方式中，圆环状箱体的内部空间中布置有多个方形电芯或软包电芯(如8个方形电芯)，每个电芯均具有电芯极耳，所述电芯极耳在电芯表面向上布置，不同电芯之间的电芯极耳的汇流排采用软连接(如电线连接)或者硬连接(如铜片连接)，具体的，这些电芯在内部空间中环绕所述圆柱形空腔的中心线呈径向旋转状(或螺旋状)分布，电芯的最大横截面均与所述圆柱形空腔的中心线不共面。相邻电芯各自的最大横截面之间的夹角为45°，这些夹角之和为360°。在可能的实施例中，可根据实际用电的需求，设计n层抱杆电源，这时，可以理解的，所有抱杆电源的夹角16之和为360°的n倍，n为大于或等于1的整数。
在又一种可能的布置方式中，圆环状箱体的内部空间中布置有多个圆柱形电芯(例如64个电芯)，每个电芯均具有电芯极耳，所述电芯极耳在电芯表面向上布置，不同电芯之间的电芯极耳的汇流排采用软连接(如电线连接)或者硬连接(如铜片连接)。这些电芯的重心围绕圆环状箱体的圆柱形空腔的中心线均匀分布，具体的，每个所述圆柱形电芯的中心线与所述圆柱形空腔的中心线平行，这些电芯在内部空间中环绕所述圆柱形空腔的中心线呈放射状分布，每条放射线路线上均匀设置有一组电芯。位于相同放射线路线的一组电芯的中心线与所述圆柱形空腔的中心线组成的面，以及，相邻的放射线路线的一组电芯的中心线与所述圆柱形空腔的中心线组成的面，这两个面之间的夹角为22.5°，这些夹角16之和为360°。
在可能的实施例中，可根据实际用电的需求，设计n层抱杆电源，这时，可以理解的，所有抱杆电源的夹角之和为360°的n倍，n为大于或等于1的整数。
另外，本发明实施例中，所述抱杆电源安装到支撑杆上的方式可以是多种多样的。安装前，活动铰链为活动连接状态，安装后，紧固另一端的可调式紧固结构，抱杆电源可基于自身结构固定到支撑杆上，或者可通过外设的上下底座部件固定到支撑杆上。
在一种可能的安装方式中，所述圆柱形空腔可用于夹紧支撑杆。当所述抱杆电源安装到支撑杆上时，通过紧固所述可调式紧固结构，可以使得所述圆柱形空腔的腔壁紧贴所述支撑杆，也就是说，当所述抱杆电源安装在所述支撑杆时，所述圆柱形空腔的半径等于所述支撑杆安装位置的半径。这样，抱杆电源可基于腔壁与支撑杆之间的摩擦力固定在所述 支撑杆上。
在又一种可能的安装方式中，抱杆电源可通过外设的部件固定到支撑杆上，例如，所述抱杆电源的圆环状箱体的圆柱形空腔两端分别设置有角钢(即每个半圆环柱状结构体空腔部位的上下沿分别设置角钢)。当抱杆电源需安装到到支撑杆上时，所述角钢的一边与所述圆环状箱体固定连接，所述角钢的一边紧贴所述支撑杆。分别设置两个半圆环柱状结构体空腔部位上沿的角钢可通过固定螺柱进行连接，分别设置两个半圆环柱状结构体空腔部位下沿的角钢也可通过固定螺柱进行连接。这样，安装完毕时，抱杆电源可通过外设的部件固定到支撑杆上。
另一种应用情况是，所述支撑杆并不是标准化的，支撑杆直径不一，事实情况是，无论支撑杆如何变化，至少可以转接一个具有标准直径的第二支撑杆，此时，所述抱杆电源还可以安装于该第二支撑杆上，此时，作用效果是等价的，还有一种应用情况是，支撑杆上下具有不均匀的直径，一般的，从下到上，直径逐渐变小，此时，抱杆电源中间的圆环也可以是渐变的，从而能够依靠重力，自然地固定在杆上(图4)，还有一种可能，抱杆电源中间的圆环状并不是打通的，上侧是封闭的，此时，所述抱杆电源可以固定于支撑杆顶部。
具体实现中，在本发明实施例中的圆环状箱体中除了布置有电芯之外，还布置有其他常规的电源辅助部件，例如电源管理系统(Battery Management System,BMS)、汇流排、加热膜，以及必要的加强件等等，这些电源辅助部件或者位于电芯之间、或者位于电芯上部，或者位于电芯下部，或者位于电芯表面，这里不做具体限定。
可以看出，本发明实施例中，通过将抱杆电源设计成中心具有一个圆柱形空腔的圆环状箱体，可使得抱杆电源安装到支撑杆后环抱所述支撑杆，又由于所述抱杆电源的多个电芯可通过多种部署方式在所述圆环状箱体中均匀布置，所以可使得所述抱杆电源的重心位于所述支撑杆的横截面(甚至中心)上。因此，实施本发明实施例能够提高抱杆电源的稳固性，避免受恶劣天气的影响，而且，由于电芯之间均匀分布，所以每个电芯的周围环境基本一致，工作时温度也一致，从而确保电芯间温度一致，即每个电芯的散热情况基本一致，避免电芯间散热不一致而导致局部过热问题，延长抱杆电源的使用寿命。另外，从上面所描述的多种电芯部署方式可以看出，本发明实施例提供的抱杆电源可扩展性较强，能够广泛适用于对电量要求越来越多的应用场景，如5G等场景，应用性较强。

具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。本发明的实施方式部分使用的术语仅用于对本发明的具体实施例进行解释，而非旨在限定本发明。
参见图2，本发明实施例提供了一种圆环柱状的抱杆电源，如图2所示，该圆环柱状的抱杆电源包括待安装到支撑杆(例如路灯等柱子)的圆环状箱体1、设置在该圆环状箱体1的内部空间2中的多个电芯(图2未示出)、以及设置在圆环状箱体1上的活动铰链5和紧固结构6。其中，圆环状箱体1的中心具有一个圆柱形空腔20，所述圆柱形空腔20可用于环抱所述支撑杆；所述多个电芯在所述圆环状箱体1的内部空间2中均匀对称地进行布置(在下文中详细描述)，这样，抱杆电源安装在支撑杆时，所述抱杆电源的重心就能够位于所述支撑杆的内部。也就是说，所述支撑杆竖直设置于地面，当所述抱杆电源安装在所述支撑杆时，所述抱杆电源的重心位于所述支撑杆的横截面上，所述横截面位于所述支撑杆的内部，且所述横截面与所述圆柱形空腔20的中心线垂直。
具体的，在所述圆环状箱体1中，所述多个电芯的重心围绕所述圆柱形空腔20的中心线均匀分布。这样，如图3中(a)所示，当抱杆电源(由圆环状箱体1所指示)安装在支撑杆10上时，所述抱杆电源的重心(F)就位于所述支撑杆10的横截面11上，在可能的实施例中，所述抱杆电源的重心甚至能位于所述支撑杆10的横截面11的中心。
本发明实施例中，在抱杆电源的圆环状箱体1设置有活动铰链5和紧固结构6，所述圆环状箱体可分为两个半圆环柱状结构体(201和202)，所述两个半圆环柱状结构体的一端的交界处(重合处)设置该活动铰链5，所述两个半圆环柱状结构体通过该活动铰链5进行可活动连接。所述两个半圆环柱状结构体的另一端的交界处(重合处)设置该可调式紧固结构6，当所述两个半圆环柱状结构体通过所述活动铰链5闭合成所述圆环状箱体1时，所述可调式紧固结构6用于锁紧所述圆环状箱体1。由于，所述抱杆电源(圆环状箱体1)可基于所述活动铰链5打开成两个半圆环柱状结构体，从而可以方便电芯在对应的内部空间2中布置，以及方便抱杆电源安装到支撑杆上。
在可能的应用场景中，本发明实施例所提供的抱杆电源可以根据需要而设计成多层组合形式。例如，参见图3中(b)，在一种组合形式中，所述抱杆电源可设计成上下双层，每一层均包括一个图2所示的圆环柱状的抱杆电源，分别为抱杆电源1a和抱杆电源1b。可以理解的，抱杆电源1a的重心位于所述支撑杆10的横截面12上，所述抱杆电源1b的重心位于所述支撑杆10的横截面13上，所以整体上的抱杆电源的重心依然位于所述支撑杆10的横截面甚至中心。
需要说明的是，在本发明实施例中的圆环状箱体1中除了布置有电芯之外，还布置有其他常规的电源辅助部件，例如电源管理系统(Battery Management System,BMS)、汇流排、加热膜，以及必要的加强件等等，这些电源辅助部件或者位于电芯之间、或者位于电芯上部，或者位于电芯下部，或者位于电芯表面，这里不做具体限定。无论是哪种布置方式， 由于电芯的总重量是抱杆电源重量的主要部分，所以本发明实施例中圆环柱状抱杆电源的重心可保持在支撑杆10的横截面。
本发明实施例中，所述抱杆电源安装到支撑杆10上的方式可以是多种多样的。安装前，活动铰链5为活动连接状态，安装后，紧固另一端的可调式紧固结构6，抱杆电源可基于自身结构固定到支撑杆10上，或者可通过外设的上下底座部件固定到支撑杆10上。
参见图4，在一种可能的实施例中，所述圆柱形空腔20可用于夹紧支撑杆10。当所述抱杆电源(圆环状箱体1)安装到支撑杆10上时，通过紧固所述可调式紧固结构6，可以使得所述圆柱形空腔20的腔壁紧贴所述支撑杆10，也就是说，当所述抱杆电源安装在所述支撑杆10时，所述圆柱形空腔20的半径等于所述支撑杆10安装位置的半径。这样，抱杆电源可基于腔壁与支撑杆10之间的摩擦力固定在所述支撑杆10上。可以理解的，这样夹紧支撑杆的形式，不仅适用于圆柱体形的支撑杆10上的抱杆电源固定，也适用于非圆柱体形(变截面)的支撑杆10上的抱杆电源固定。
参见图5中(a-c)，在又一种可能的实施例中，抱杆电源可通过外设的部件固定到支撑杆10上，如图5所示，所述抱杆电源的圆环状箱体1的圆柱形空腔20两端分别设置有角钢8(即每个半圆环柱状结构体的空腔部位的上下沿分别设置角钢8)。当抱杆电源需安装到到支撑杆10上时，所述角钢8的一边与所述圆环状箱体1固定连接(角钢8紧固形成上下固定底座)，所述角钢8的一边紧贴所述支撑杆10。分别设置两个半圆环柱状结构体空腔部位上沿的角钢8可通过固定螺柱9进行连接，分别设置两个半圆环柱状结构体空腔部位下沿的角钢8也可通过固定螺柱9进行连接。这样，安装完毕时，抱杆电源可通过外设的部件固定到支撑杆10上。
需要说明的是，为了使抱杆电源在支撑杆10上更加紧固，在具体应用场景中，设置在空腔部位的上沿的角钢8之间的固定螺柱9可以有多个，设置在空腔部位的下沿的角钢8之间的固定螺柱9可以有多个。如图5中c所示，设置在空腔部位的上(下)沿的角钢8之间的固定螺柱9可以有4个，这4个固定螺柱9分别连接在角钢8之间，达到了紧固抱杆电源到支撑杆10的目的。
可以理解的是，在具体实现中，所述圆柱形空腔20的半径(即圆环状箱体1的内径)不小于所环抱的支撑杆横截面的半径，所述圆环状箱体1的高度不小于部署在其内部的电芯的高度。
可以看出，本发明实施例中，通过将抱杆电源设计成中心具有一个圆柱形空腔的圆环状箱体，可使得抱杆电源安装到支撑杆后环抱所述支撑杆，又由于所述抱杆电源的多个电芯在所述圆环状箱体中均匀布置，所以可使得所述抱杆电源的重心位于所述支撑杆的横截面(甚至中心)上。因此，实施本发明实施例能够提高抱杆电源的稳固性，另外，由于电芯之间均匀分布，所以每个电芯的周围环境基本一致，所以每个电芯的散热情况也会基本一致，避免电芯间散热不一致而导致局部过热问题，延长抱杆电源的使用寿命。
下面详细描述在圆环状箱体1的内部空间2中多个电芯的布置方式。
在一种可能的电芯布置方式中，参见图6，图6是本发明实施例提供的一种抱杆电源的俯视图，如图6所示，圆环状箱体1的内部空间2中布置有多个电芯3(图示中为16个 电芯3)，每个电芯3均具有电芯极耳4，所述电芯极耳在电芯表面向上布置，不同电芯之间的电芯极耳的汇流排采用软连接(如电线连接)或者硬连接(如铜片连接)，其中，为了方便圆环状箱体1的开合，位于所述活动铰链5附近的相邻电芯的电芯极耳41和42采用软连接，同理，位于可调式紧固结构6附近的电芯极耳也采用软连接。这些电芯的重心围绕圆环状箱体1的圆柱形空腔20的中心线均匀分布，具体的，这些电芯为方形电芯或软包电芯，这些电芯在内部空间2中环绕所述圆柱形空腔20的中心线呈径向放射状分布。每个电芯的最大横截面(如71或72所示)均与所述圆柱形空腔20的中心线共面。相邻电芯各自的最大横截面之间(如71和72之间)的夹角为图示中夹角7，由于电芯围绕支撑杆中心线均匀分布，所以电芯间夹角7为22.5°，这些夹角7之和为360°。
在可能的实施例中，可根据实际用电的需求，以参考图3中(b)的形式布置n层抱杆电源，这时，可以理解的，所有抱杆电源的夹角7之和为360°的n倍，n为大于或等于1的整数。
下面进一步描述这种圆环柱状的抱杆电源打开和闭合的状态。参见图7中(a-c)，其中，图7中(a)示出了这种抱杆电源分成两个半圆环柱状结构体的俯视图，图7中(b)示出了这种抱杆电源打开状态的的俯视图，图7中(c)示出了这种抱杆电源闭合状态的的俯视图。
如图7中(a)所示，抱杆电源的圆环状箱体由两个半圆环柱状结构体201和202组合而成，半圆环柱状结构体201的一端的设置有活动铰链5的组成结构51，半圆环柱状结构体202的一端的设置有活动铰链5的组成结构52，组成结构51和组成结构52可通过可活动连接组合成铰链结构5，从而使得所述两个半圆环柱状结构体201和202通过所述活动铰链5进行可活动连接。另外，半圆环柱状结构体201的另一端的设置有可调式紧固结构6的组成结构61，半圆环柱状结构体202的另一端的设置有可调式紧固结构6的组成结构62，组成结构61和组成结构62可重合，并通过相关部件可调式固定在一起，组成可调式紧固结构6，例如，组成结构61和组成结构62重合后组成螺栓，该螺栓可使用螺母进行可调式固定，从而组成可调式紧固结构6，所述可调式紧固结构6用于锁紧所述圆环状箱体1。
如图7中(b)(c)所示，所述抱杆电源(圆环状箱体1)可基于所述活动铰链5打开成两个半圆环柱状结构体201和202，从而可以方便电芯在201对应的内部空间和202对应的内部空间中进行布置，两个半圆环柱状结构体201和202可分别布置有一半数量的电芯3(图示中分别具有8组电芯)，同时也方便抱杆电源自打开的空隙中安装到支撑杆。当抱杆电源安装到支撑杆时，闭合两个半圆环柱状结构体201和202，则圆柱形空腔20环抱所述支撑杆，然后锁紧所述可调式紧固结构6，则抱杆电源可通过图4或者图5实施例所示方式固定在支撑杆上。
可以理解的是，在本发明实施例中的圆环状箱体1中除了布置有这些电芯3之外，还布置有其他常规的电源辅助部件，例如BMS、汇流排、加热膜，以及必要的加强件等等，这些电源辅助部件或者位于电芯之间、或者位于电芯上部，或者位于电芯下部，或者位于电芯表面，此外，还可以理解的是，圆环状箱体1外还可能设置有角钢8和固定螺柱9等等，这里不做具体限定。
在又一种可能的电芯布置方式中，参见图8，图8是本发明实施例提供的又一种抱杆电源的俯视图，如图8所示，圆环状箱体1的内部空间2中布置有多个电芯14(图示中为8个电芯3)，每个电芯14均具有电芯极耳15，所述电芯极耳15在电芯表面向上布置，不同电芯之间的电芯极耳的汇流排采用软连接(如电线连接)或者硬连接(如铜片连接)，其中，为了方便圆环状箱体1的开合，位于所述活动铰链5和可调式紧固结构6附近的相邻电芯的电芯极耳可采用软连接。这些电芯的重心围绕圆环状箱体1的圆柱形空腔20的中心线均匀分布，具体的，这些电芯为方形电芯或软包电芯，这些电芯在内部空间2中环绕所述圆柱形空腔20的中心线呈径向旋转状(或螺旋状)分布，电芯的最大横截面均与所述圆柱形空腔20的中心线不共面。相邻电芯各自的最大横截面之间的夹角为图示中夹角16，由于电芯围绕支撑杆中心线均匀分布，所以电芯间夹角16为45°，这些夹角16之和为360°。
在可能的实施例中，可根据实际用电的需求，以参考图3中(b)的形式布置n层抱杆电源，这时，可以理解的，所有抱杆电源的夹角16之和为360°的n倍，n为大于或等于1的整数。
同样，这种圆环柱状的抱杆电源也可分为两个半圆环柱状结构体(图未示出)，这两个半圆环柱状结构体可以基于活动铰链5进行打开和闭合，当其闭合时，可调式紧固结构6用于锁紧所述抱杆电源，具体实现方式可参考图7中实施例的相关描述，这里不再赘述。
可以理解的是，在本发明实施例中的圆环状箱体1中除了布置有这些电芯3之外，还布置有其他常规的电源辅助部件，例如BMS、汇流排、加热膜，以及必要的加强件等等，这些电源辅助部件或者位于电芯之间、或者位于电芯上部，或者位于电芯下部，或者位于电芯表面，此外，还可以理解的是，圆环状箱体1外还可能设置有角钢8和固定螺柱9等等，这里不做具体限定。
在又一种可能的电芯布置方式中，参见图9，图9是本发明实施例提供的又一种抱杆电源的俯视图，如图9所示，圆环状箱体1的内部空间2中布置有多个电芯17(图示中为64个电芯17)，每个电芯17均具有电芯极耳18，所述电芯极耳18在电芯表面向上布置，不同电芯之间的电芯极耳的汇流排采用软连接(如电线连接)或者硬连接(如铜片连接)，其中，为了方便圆环状箱体1的开合，位于所述活动铰链5和可调式紧固结构6附近的相邻电芯的电芯极耳可采用软连接。这些电芯的重心围绕圆环状箱体1的圆柱形空腔20的中心线均匀分布，具体的，这些电芯均为圆柱形电芯；每个所述圆柱形电芯的中心线与所述圆柱形空腔20的中心线平行，这些电芯在内部空间2中环绕所述圆柱形空腔20的中心线呈放射状分布，每条放射线路线上均匀设置有一组电芯(图中一组电芯包括4个电芯)。如图所示，位于相同放射线路线的一组电芯的中心线与所述圆柱形空腔的中心线组成的面为191，相邻的放射线路线的一组电芯的中心线与所述圆柱形空腔的中心线组成的面为192，191与192之间的夹角为夹角19，由于每组电芯围绕支撑杆中心线均匀分布，所以夹角19为22.5°，这些夹角16之和为360°。
在可能的实施例中，可根据实际用电的需求，以参考图3中(b)的形式布置n层抱杆 电源，这时，可以理解的，所有抱杆电源的夹角16之和为360°的n倍，n为大于或等于1的整数。
同样，这种圆环柱状的抱杆电源也可分为两个半圆环柱状结构体(图未示出)，这两个半圆环柱状结构体可以基于活动铰链5进行打开和闭合，当其闭合时，可调式紧固结构6用于锁紧所述抱杆电源，具体实现方式可参考图7中实施例的相关描述，这里不再赘述。
可以理解的是，在本发明实施例中的圆环状箱体1中除了布置有这些电芯3之外，还布置有其他常规的电源辅助部件，例如BMS、汇流排、加热膜，以及必要的加强件等等，这些电源辅助部件或者位于电芯之间、或者位于电芯上部，或者位于电芯下部，或者位于电芯表面，此外，还可以理解的是，圆环状箱体1外还可能设置有角钢8和固定螺柱9等等，这里不做具体限定。
需要说明的是，上述实施例仅用于解释本发明实施例可能的实现方案，而非限定。在实际应用中，可根据本发明技术方案的思想对电源结构、电芯布置方式等进行相应的变形和组合。
比如，在一种可能的变形中，图8所示的实施例中，电芯14可沿着圆柱体空腔20的中心线方向采用均匀螺旋上升的方式进行布置，这样，所有抱杆电源的夹角16之和可为360°的m倍，m为大于1的整数。
又比如，抱杆电源可包括多层圆环状箱体，每层圆环状箱体可分别采用图6、图8、图9实施例以及其他变形实施例中任意一种方案进行组合设计，这样的组合方式同样属于本发明的保护范围。
另外，还需要说明的是，虽然本发明实施例中所描述的多个电芯的重心皆围绕所述圆柱形空腔的中心线均匀分布，但是，在可能的实施例中，所述抱杆电源的圆环状箱体中除了均匀分布的电芯外，也有可能根据需要设置少数非均匀分布的电芯，这种情况下，所述抱杆电源的重心依然能够位于所述支撑杆的内部。
可以看出，本发明实施例中，通过将抱杆电源设计成中心具有一个圆柱形空腔的圆环状箱体，可使得抱杆电源安装到支撑杆后环抱所述支撑杆，又由于所述抱杆电源的多个电芯可通过多种部署方式在所述圆环状箱体中均匀布置，所以可使得所述抱杆电源的重心位于所述支撑杆的横截面(甚至中心)上。因此，实施本发明实施例能够提高抱杆电源的稳固性，避免受恶劣天气的影响，而且，由于电芯之间均匀分布，所以每个电芯的周围环境基本一致，工作时温度也一致，从而确保电芯间温度一致，即每个电芯的散热情况基本一致，避免电芯间散热不一致而导致局部过热问题，延长抱杆电源的使用寿命。另外，从上面所描述的多种电芯部署方式可以看出，本发明实施例提供的抱杆电源可扩展性较强，能够广泛适用于对电量要求越来越多的应用场景，如5G等场景，应用性较强。
在上述实施例中，对各个实施例的描述各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
以上为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何熟悉本领域的技术人员在本申请揭露的技术范围内，可轻易想到各种等效修改或替换，这些修改或替换都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
