相关技术中的振荡器，采用三个偏心轴实现旋转振动时，是以其中一个偏心轴作为主动轴，带动另外的两个偏心轴转动，从而达到振荡效果。由于这类振荡器是一轴带动两轴，就需要在主动轴处增加一配重块。而且在单一偏心主动轴处加上配重块，需要额外为配重块的旋转预留空间，以及需要稳定振荡器而增设底盘等零部件。并且在振荡器运行时，配重块不是以几何中心做旋转，会导致主动轴不仅需要承受径向压力，还同时需要承受配重块旋转时产生的水平方向上的压力，这就对主动轴有很高的强度要求。也因此，这类振荡器的转速不能太高，负载不能过大，不然配重块产生的离心力过大，影响到主动轴的寿命，从而影响到振荡器的寿命。对于有大量振荡需求的实验时，此类振荡器难以满足要求，且无法进行长时间振荡。
针对上述问题，本申请实施例提供一种振荡装置及实验设备，能够提升振荡装置在高速及长时间振荡时的运行稳定性，可以满足具有高速、大负载和长时间振荡需求的实验。
以下结合附图详细描述本申请实施例的技术方案。
图1是本申请实施例示出的振荡装置的结构示意图；图2是图1中示出的振荡装置的转动件的安装示意图。
参见图1和图2，本申请提供的振荡装置，包括底板110以及可转动地安装于底板110的三个转动件111；底板110上侧设有托板130，下侧设有配重块120，转动件111的两端分别位于底板110的上下两侧，且分别通过偏心结构与托板130和配重块120固定连接；还包括驱动装置，三个转动件111位于虚拟三角形的三个顶点，驱动 装置的输出轴141垂直于虚拟三角形，且与三个转动件111传动相连，用于驱动三个转动件111同步转动。本实施例的振荡装置在运行时，三个转动件111可带动托板130产生振荡，由于配重块120设于三个转动件111的底部，且通过偏心结构与三个转动件111固定连接，因此，配重块120产生的离心力可由三个转动件111共同分担，不仅可以承载更大的振荡载荷，而且提升了振荡装置在高速及长时间振荡时的运行稳定性，可以满足具有高速、大负载和长时间振荡需求的实验。
与现有振荡器中配重块仅与一个转动件连接的方案相比，本申请将配重块120同时与三个转动件111连接，从安装上来说更为稳定，且能够承受更大的负载和转速，也降低了对转动件111的强度要求，以及在振荡工作过程中，不易使转动件发生物理疲劳(形变)而影响整个振荡装置的寿命，从而使得整个振荡装置的稳定性更好，能够长时间持续工作。
图3是图1中示出的振荡装置的转动件111的立体结构示意图；图4是图1中示出的振荡装置的转动件111的侧视图。
参见图1至图4，一些实施例中，转动件111包括轴体1110，轴体1110的两端分别设有第一偏心连接轴1111和第二偏心连接轴1112，转动件111通过第一偏心连接轴1111连接于托板130，通过第二偏心连接轴1112连接于配重块120；第一偏心连接轴1111的轴心、第二偏心连接轴1112的轴心均与轴体1110的轴心相平行，且分别位于轴体1110的径向两侧。
一些实施例中，转动件111的第一偏心连接轴1111通过上轴承座131连接于托板130，第二偏心连接轴1112通过下轴承座122连接于配重块120。驱动装置可以驱动三个转动件111自转，三个转动件111自转时，可通过第一偏心连接轴1111带动上侧的托板130运动，同时通过第二偏心连接轴1112带动下侧的配重块120运动。由于第一偏心连接轴1111和第二偏心连接轴1112分别位于转动件111的轴体1110的径向两侧，因此，当托板130和配重块120的运动方向相反，使得配重块120可以缓冲托板130产生的离心力，同时，托板130也可以缓冲配重块120产生的离心力，进而提升了振荡装置的运行稳定性，不仅能满足高速振荡的要求，例如托板130的运动最大可以达到1200转/分钟；也能满足长时间振荡的要求，例如可以进行长达48小时的振荡实验；而且还能承受更大的振荡载荷，例如振荡载荷可达2kg。
一些实施例中，由于转动件111需要承受轴向力和径向力，为了保证转动件111的强度，第一偏心连接轴1111和第二偏心连接轴1112可以成型为一体，这样可以提 高转动件111整体的结构强度。一些实施例中，转动件111采用强度较高的金属材质制成，例如包括但不限于303不锈钢。
本实施例中，转动件111带动配重块120旋转时，配重块120会产生离心力。旋转速度越快，产生的离心力也越大，配重块120作用于转动件111的径向力也越大。本实施例中，由于三个转动件111均连接于配重块120，且通过下轴承座122的连接进行缓冲，因此降低了配重块120作用于转动件111的径向力，提升了转动件111寿命。
驱动装置可以包括电机140，电机140的输出轴141安装有主动轮1411，三个转动件111分别安装有从动轮1114，电机140的输出轴141通过柔性传动件150与三个转动件111传动相连，柔性传动件150绕设于主动轮1411与三个从动轮1114之间。柔性传动件150包括双面齿同步带，主动轮1411转动时，可通过双面同步带带动三个从动轮1114同步转动。使用同步带传动，既降低了振荡过程产生的噪音，又可以降低三个转动件111因加工和装配过程中产生的相位误差，保证了振荡装置的运行精度。
本实施例中，三个转动件111的结构相同，虚拟三角形为等腰三角形，输出轴141穿设于虚拟三角形的重心位置，这样设置后，能够保证主动轮1411每次转动的时候，虚拟三角形每条边对应的双面齿同步带转动的齿数是一样的，使振荡装置在运行时减少晃动，稳定性更高。另外，和相关技术相比，减少了配重块120旋转的预留空间，可无需设置用于稳定振荡装置的底盘等零部件。节省了空间，降低了成本，又降低了振荡装置的整体重量，体积更小，使得相同面积的试验台可以放置多台振荡装置，便于同时进行不同的振荡实验。另外，采用上述结构设置，使得托板130及其承载的物质的偏心振荡与配重块120的偏心振荡能够相互抵消，从而提高了振荡装置的稳定性。
一些实施例中，转动件111的偏心距相同，即转动件111的轴体1110的轴心到转动件111的第一偏心连接轴1111的轴心的距离，与到转动件111的第二偏心连接轴1112的轴心的距离相等，从而使得托板130与配重块120的振幅相同，例如偏心距可以为2.5毫米，振幅则为5毫米。这样能够进一步提高振荡装置的稳定性。
一些实施例中，在安装三个转动件111时，可以使得三个转动件111的相位一致，这样能够保证三个转动件111同步转动，以提高振荡装置的稳定性。
采用上述结构设置，振荡装置在工作时，托板130及其承载的物质会产生水平方向的力，而配重块120会产生一个相反方向的力，它们之间可以互相抵消，从而实现 转动过程中整个振荡装置的稳定性。
一些实施例中，驱动装置相对于底板110可活动设置；电机140和底板110之间设有张紧调节机构，张紧调节机构用于调节主动轮1411和三个从动轮1114之间的相对位置，以调节柔性传动件150的张紧力，这样能避免柔性传动件150长时间运行后产生松动。
一些实施例中，电机140固定于安装板142，安装板142相对于底板110可活动设置；张紧调节机构包括固定于底板110的调节固定块、固定于安装板142的张紧力调节块143以及连接于调节固定块和张紧力调节块143之间的螺纹调节件。调节固定块和张紧力调节块143可以设于底板110的底部，且位于电机140的一侧。
螺纹调节件可以是连接于调节固定块和张紧力调节块143之间的螺钉，旋转螺钉时，可以使调节固定块和张紧力调节块143之间产生相对运动，进而使电机140与底板110之间产生相对运动，使得主动轮1411和三个从动轮1114之间的间距产生轻微变化，从而实现调节柔性传动件150张紧力的目的。张紧力调节机构还可以对电机140起到稳定的作用，能防止电机140的输出轴141受到同步带的拉力而产生偏移。
一些实施例中，底板110的中部可以开设第一中空部112，配重块120的中部可以开设第二中空部121；第一中空部112和第二中空部121上下相对，电机140包括与输出轴141相连的主体，输出轴141穿设于第一中空部112，主体穿设于第二中空部121，这样设置后，使得振荡装置的结构更为紧凑，可以减小空间占用和降低振荡装置的重量。
一些实施例中，振荡装置还设有用于限定转动件111的转动位置的开关部件113，开关部件113可以安装于底板110的上侧，同时可以在转动件111的轴体1110上设置和开关部件113限位配合的限位件1113，使振荡装置工作完成后，托板130能停止在特定的位置上或转动件111的限位件1113能停止在特定的位置上。其中，开关部件113可以包括光电开关，但不限于此。另外，限位件1113还起到平衡转动件111的作用，因为转动件111在安装时，位于底板110下侧的部位会长于位于底板110上侧的部位，这样会使得上下两部分重量不一致，转动时容易产生晃动。而在转动件111的上侧增加限位件1113，能够平衡转动件111上下两部分的重量，保证转动件111在转动时能够更加稳定。
图5是申请实施例示出的振荡装置的容器承载装置的安装结构示意图。
参见图5，本申请的振荡装置还包括容器承载装置，容器承载装置与托板130相 连，容器承载装置设有若干容器放置槽211，容器放置槽211内安装有弹性限位件230，弹性限位件230用于将容器限定于容器放置槽211内。容器可以是试管，但不限于此，托板130运动时，可带动容器承载装置运动，进而对容器内的溶液进行振荡。
图9是本申请实施例示出的振荡装置的弹性限位件的结构示意图。
参见图9，一些实施例中，弹性限位件230由具有弹性变形能力的金属材料制成，弹性限位件230包括固定部231以及与固定部231设为一体，且能相对于固定部231弹性活动的活动部232，固定部231相对于容器承载装置固定设置，例如可以通过螺钉固定于容器放置槽211的槽口2111处，活动部232收容于容器放置槽211内，用于和放置于容器放置槽211内的容器的外壁弹性抵紧，进而实现对容器的限位。
一些实施例中，容器放置槽211在容器承载装置的顶部自上而下开设，容器放置槽211的上侧设有开口，容器放置槽211的直径可以大于容器的直径，容器可以自开口自上而下的放置于容器放置槽211内。弹性限位件230收容于容器与容器放置槽211的内壁之间的间隙内，活动部232可以弹性抵紧于容器的外壁，使容器和容器放置槽211之间不会产生相对活动。
一些实施例中，活动部232可以设为两个，且相间隔后形成间隙233，使得弹性限位件230的形状呈U形，两个活动部232可同时弹性抵紧于容器外壁，这样对容器具有更好的限位效果。
弹性限位件230不仅可以防止容器在振荡时因运动而破裂，而且在振荡时，容器本身不会因惯性而振动，全程跟随容器承载装置而运动，使溶液的振荡效率更高；另外在振荡速度稳定时进行状态(如溶清状态、结晶状态等)检测，可以使容器中的物质处于相对稳定的状态，利于得出更准确的检测结果。
本实施例的容器承载装置包括开设有若干容器放置槽211的基体210，基体210由导热性材质制成。

一些实施例中，温度控制组件还包括用于将加热膜固定于基体210的压板320，可以将加热膜粘接与压板320，再将压板320使用螺钉等连接件固定在基体210的底部，使加热膜夹设于压板320和基体210的底部之间。

一些实施例中，第一检测装置包括分设于容器承载装置两侧的激光发射模块和激光接收模块430，激光发射模块发出的激光束穿出容器放置槽211后可被激光接收模块430接收。可以在基体210上对应于容器放置槽211的部位开设沿侧向贯通的通道 2112，激光发射模块发出的激光束可以经由该通道2112照射于容器中的溶液后并被激光接收模块430接收，进而实现对溶液清澈度的检测。
另外，U形设置的弹性限位件230在安装时，其间隙233对准基体210上的通道2112，这样有利于第一检测装置通过激光检测容器放置槽中的容器(例如试管)中的物质状态，从而实现对容器中物质状态的检测。
