本发明属于电梯供电的技术领域，尤其涉及一种磁环感应式电梯供电系统。
背景技术
现阶段国内电梯的能量消耗每年都比较大，随着社会可持续发展的深入，节能环保也已经成为了各大发展领域的重点战略方针。现阶段的载人或者是载货电梯都是将市电引入到电梯供电系统当中，为电梯供电系统提供有效电源，高层电梯一般都是配置两路的独立供电电源，但是如果发生大面积停电两路电源都不可用的时候，仅依靠应急电源所储备的电量不足以给各楼道提供应急照明和应急电力的同时，还能给电梯提供继续工作的电量。
发明内容
基于以上现有技术的不足，本发明所解决的技术问题在于提供一种磁环感应式电梯供电系统，通过对各电梯中磁环感应发电器所产生的电量进行收集并储存在一个比较大的蓄电池当中，保证当发生停电时能够为电梯的正常运行提供电量。
为了解决上述技术问题，本发明通过以下技术方案来实现：本发明提供一种磁环感应式电梯供电系统，包括：
磁环感应发电器，安装在电梯牵引电机的输出轴上，用于在电梯牵引 电机的输出轴旋转时带动磁环感应发电器旋转发电；

由上，本发明的磁环感应式电梯供电系统的磁环感应发电器安装在电机旋转轴上，当电机转动时，磁环感应发电器开始发电，其输出端与蓄电池相连，两者中间有磁环感应控制器对磁环感应发电器是否开始工作(向蓄电池传输电量)进行控制；电梯所用电机为交流电机时，蓄电池输出端连接逆变器，逆变器将蓄电池内的直流电转换为交流电；当电梯所用电机 为直流电机时，市电电源输出端则连接整流器，将市电电源提供的交流电转换为直流电供电机使用；市电电源与蓄电池电源切换通过电源控制器来实现，最后通过配电柜将电能合理分配至电梯各个用电设备上。该系统以磁环感应发电器产生的电能提供电梯各个系统的平稳运行，不但减少资源利用，而且还减少对环境的污染，同时还提高了电梯的工作效率。
上述说明仅是本发明技术方案的概述，为了能够更清楚了解本发明的技术手段，而可依照说明书的内容予以实施，并且为了让本发明的上述和其他目的、特征和优点能够更明显易懂，以下结合优选实施例，并配合附图，详细说明如下。
附图说明
为了更清楚地说明本发明实施例的技术方案，下面将对实施例的附图作简单地介绍。
图1为本发明实施例一的磁环感应式电梯供电系统的结构示意图；
图2为本发明实施例二的磁环感应式电梯供电系统的结构示意图。
具体实施方式
下面结合附图详细说明本发明的具体实施方式，其作为本说明书的一部分，通过实施例来说明本发明的原理，本发明的其他方面、特征及其优点通过该详细说明将会变得一目了然。在所参照的附图中，不同的图中相同或相似的部件使用相同的附图标号来表示。
如图1-2所示，本发明提供了一种磁环感应电梯供电技术，本发明的磁环感应式电梯供电系统主要包括磁环感应发电器10、磁环感应控制器20和蓄电池30，磁环感应发电器10安装在电梯牵引电机的输出轴上，用于在电梯牵引电机的输出轴旋转时带动磁环感应发电器旋转发电，磁环感应 发电技术具有结构简单、牢固、体积小、重量轻、运行维护方便、辅助设备少以及成本较低等优点；磁环感应控制器20与所述磁环感应发电器10连接，用于对所述磁感应发电器10是否进行发电进行控制；蓄电池30的输入端所述磁环感应发电器10连接，用于将所述磁环感应发电器产生的电量进行储存。由于电梯牵引电机有交流电机和直流电机，下面将结合结构示意图1和图2对本发明分别作出相关说明。
实施例一
如图1所示，本发明实施例一的磁环感应式电梯供电系统包括：磁环感应发电器10、磁环感应控制器20、蓄电池30、逆变器40、蓄电池控制器31、电源控制器50、电源开关60、配电柜70、以及市电电源80。所述磁环感应发电器10为该供电系统中核心部分，该磁环感应发电器10安装在电梯牵引电机的输出轴上，在电梯牵引电机的输出轴旋转同时带动磁环感应发电器发电，电能被储存在蓄电池30中。蓄电池30与磁环感应发电器10之间有一个磁环感应控制器20，磁环感应控制器20能够控制磁环感应发电器的工作状态，当蓄电池30充电已满或者放电过多时，磁环感应控制器20可以控制磁环感应发电器10工作或停止工作，从而间接达到对蓄电池30的保护作用，延长蓄电池使用寿命。
本发明的逆变器40的输入端连接蓄电池30的输出端，其作用是将蓄电池30内储存的直流电源经过逆变器转换为交流电源。
本发明的蓄电池控制器31的输入端连接蓄电池30的输出端，蓄电池控制器31的输出端连接逆变器40的输入端，蓄电池控制器31的作用是控制蓄电池充电、放电以及记录蓄电池充电量和放电量总量。所述电源控制器50的输入端与所述逆变器40的输出端及电源开关60的输出端连接，能控制接入电源为市电电源或者蓄电池电源。
本发明的配电柜70的输入端与所述电源控制器50的输出端连接，可 以将蓄电池30内电源或市电电源进行合理分配，并输送到下一级用电设备中。
本发明实施例一的工作原理如下：电源控制器50首先控制切换至市电电源供电，电源开关60打开，电能经过配电柜分配之后为电梯整个用电系统进行供电，电梯牵引电机(交流电机)随即开始工作，磁环感应控制器20控制安装在电机输出轴部分的磁环感应发电器10开始进行发电，产生的电能通过磁环感应发电器10的输出端传送至蓄电池30中进行储存，当蓄电池30内储存的电量足够大时，蓄电池控制器31会控制蓄电池30进行放电，蓄电池内电能经过逆变器40将直流电变换为交流电，电源开关60断开，电源控制器50控制电源切换为使用蓄电池中电能，再经过配电过分配之后传送至整个电梯用电系统。
实施例二
如图2所示，本发明实施例二的磁环感应式电梯供电系统与实施例一相比，除缺少一个逆变器40之外多了一个整流器90，其余结构全部一样，本发明实施例二的工作原理也与实例1完全一致，只是从蓄电池30中放出的直流电不需要经过逆变器40，由于实施例二所用的电梯牵引电机为直流电机，所以不需要将直流电转换为交流电。同样，电梯牵引电机此时持续保持工作，此时磁环感应发电器10也会一直保持发电。这样就保持供电系统中有源源不断的电能，只有遇到特殊情况需要对磁环感应发电器10进行检修时或设备首次安装这段时间内使用市电电源，使用市电电源的时候在市电电源80与电源开关60之间设置一个整流器90，该整流器90的作用是将市电电源中的交流电经过整流器整流后变为直流电，以供电梯牵引电机(直流电机)使用。这样整个系统的运行不但节约了能源，还能减少对环境的污染，同时为实现可持续发展战略做出巨大贡献。因此本发明的磁环感应电梯供电技术是一种非常科学、高效的电梯供电技术。
另外，本发明的磁环感应发电器10的具体型号、发电能力大小都需要根据实际工况进行选择，它的主要作用就是利用磁环感应进行发电，然后将电量储存至蓄电池内，当遇到紧急情况时可以启用蓄电池内电量，进而保证电梯不间断平稳运行；或者使用蓄电池内的电量为电梯其他控制板面提供电源。本发明采用上述技术方案为电梯运行进行供电，磁环感应发电器优势在于当电动机工作时，磁环感应发电器即可进行发电，然后将电能储存至蓄电池内。当蓄电池内储存足够电能时，电源控制器就会控制电源开关停止使用市电电源，开启使用蓄电池内电能，在使用蓄电池内电能的同时磁环感应发电器也会不断进行发电，能够保证电梯平稳运行。如磁环感应发电器发生设备故障等，就会切换至市电电源使电梯安全平稳运行。这样减少对市电电源的使用不但可以节约能源的使用，对环保事业做出很大贡献，也能保证电梯不间断运行，提高工作效率，还能减少成本投入。本发明磁环感应电梯供电技术是一种非常科学、高效的电梯供电技术。
本发明提供的磁环感应式电梯供电系统可以通过电机旋转带动磁环感应发电器工作进而达到发电以供整个电梯电力系统使用的目的，使用该磁环感应式电梯供电系统能够减小使用市电电源，以使用磁环感应发电器发电、蓄电池储存的电能为主，可以提高整个电梯系统的工作效率，加强电梯运行时稳定性，同时可以尽可能避免停电对电梯运行带来的影响，达到提升电梯工作效率同时还实现节约能源、保护环境的目的。
以上所述是本发明的优选实施方式而已，当然不能以此来限定本发明之权利范围，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以做出若干改进和变动，这些改进和变动也视为本发明的保护范围。
