具体实施方式
下面详细描述本公开的实施例，所述实施例的示例在附图中示出。下面通过参考附图描述的实施例是示例性的，旨在用于解释本公开，而不能理解为对本公开的限制。
本公开旨在至少在一定程度上解决相关技术中的技术问题之一。为此，本公开的实施例提出一种非线性混合耗能减振阻尼器，该非线性混合耗能减振阻尼器通过耗能组件对阻尼器内的机械能再消耗，提高了阻尼器的减振效果。
以下结合附图描述本公开实施例的非线性混合耗能减振阻尼器。
如图1-图3所示，本公开实施例的非线性混合耗能减振阻尼器包括第一壳体1、第二壳体2和耗能组件3，第一壳体1内填充有第一填充液11，第二壳体2可滑动连接于第一壳体1内，第二壳体2内填充有颗粒群21，耗能组件3连接于第一壳体1内，耗能组件3包括第一连杆31、第一弹性件32和扇板33，第一连杆31的第一端可转动连接于第一壳体1的内壁，第一连杆31的第二端与第二壳体2的侧壁相接触并相对于第二壳体2可滑动，第一弹性件32的第一端连接于第一壳体1的内壁，第一弹性件32的第二端连接于第一连杆31，第一弹性件32用于保持第一连杆31的第二端与第二壳体2的侧壁相接触，扇板33连接于第一连杆31。
需要说明的是，当建筑物100振动时，第二壳体2在惯性的作用下带动第一连杆31摆动，第一连杆31带动扇板33相对于第一填充液11移动，第一连杆31对第一填充液11产生推力以对第一填充液11回馈机械能，从而使第一填充液11晃动，第一填充液11分别与第一壳体1的内壁和第二壳体2的外壁摩擦进行耗能，同时第一填充液11由于内摩擦力对扇板33产生的机械能进行损耗；颗粒群21在惯性的作用下与第二壳体2发生行对移动，颗粒群21与第二壳体2内壁产生摩擦且颗粒群21内部产生摩擦以对机械能进行损耗。
本公开实施例的非线性混合耗能减振阻尼器通过第二壳体2和第一弹性件32带动第一连杆31进行摆动，第一连杆31带动扇板33与第一填充液11相对运动并给第一填充液11施加推力以对第一填充液11回馈机械能，第一填充液11对回馈的机械能进行摩擦损耗从而加速了非线性混合耗能减振阻尼器内的机械能的损耗，提高了非线性混合耗能减振阻尼器的减振效率。
如图1-图3所示，在一些实施例中，耗能组件3包括两个第一固定块36、两个第一连杆31、两个第一弹性件32和多个扇板33，两个第一固定块36固定连接于第一壳体1的内壁并沿前后方向间隔分布，两个第一连杆31与两个第一固定块36一一对应，且第一连杆31可转动连接于对应的第一固定块36上，两个第一弹性件32与两个第一连杆31一一对应，且第一弹性件32的一端连接于第一壳体1的内壁，第一弹性件32的另一端连接于对应的第一连杆31，多个扇板33均连接于第一连杆31并沿第一连杆31的长度方向间隔分布，扇板33的一端连接于其中一个第一连杆31，扇板33的另一端连接于另一个第一连杆31。
在一些实施例中，第一弹性件32为弹簧。
在一些实施例中，第一填充液11和第二壳体2占第一壳体1内部空间的80％，使第一壳体1的内部空间剩余20％用于第一填充液11和第二壳体2移动；颗粒群21由直径小于10mm的混凝土颗粒组成，且颗粒群21占第二壳体2内部空间的70％。
如图1和图2所示，在一些实施例中，耗能组件3还包括滚筒34，滚筒34可转动连接于第一连杆31的第二端，滚筒34的外壁与第二壳体2的侧壁相接触并相对于第二壳体2可 滚动，滚筒34将第一连杆31与第二壳体2之间的滑动摩擦变成滚动摩擦，避免第一连杆31与第二壳体2之间摩擦力过大而导致第二壳体2无法正常带动第一连杆31摆动。
如图1和图2所示，在一些实施例中，耗能组件3还包括安装块35，安装块35一端连接于第一连杆31的第二端，安装块35的另一端套设在滚筒34上并以滚筒34的轴线为回转中心可转动，便于第一连杆31安装在滚筒34上。
如图1-图3所示，在一些实施例中，扇板33的截面形状呈弧形，扇板33有多个，多个扇板33沿第一连杆31的长度方向间隔设置，提高了扇板33对第一填充液11传递机械能的效率。
如图1和图6所示，在一些实施例中，非线性混合耗能减振阻尼器还包括上限位板23和下限位板24，第一壳体1上设有长度沿水平方向设置的两个滑槽(未示出)，两个滑槽沿竖直方向间隔分布，上限位板23连接于第二壳体2顶壁并置于其中一个滑槽内，下限位板24连接于第二壳体2底壁并置于另一个滑槽内，上限位板23和下限位板24保证了第二壳体2沿水平方向滑动以推动第一连杆31摆动。
如图1和图6所示，在一些实施例中，非线性混合耗能减振阻尼器还包括多个挡板22组，多个挡板22组均连接于第二壳体2内并沿竖直方向间隔分布，挡板22组包括多个挡板22，挡板22倾斜设置，多个挡板22沿水平方向间隔分布，颗粒群21相对于第二壳体2移动时与挡板22摩擦，进一步提高了非线性混合耗能减振阻尼器的耗能效率。
如图1、图3-图5所示，在一些实施例中，非线性混合耗能减振阻尼器还包括复位组件4，复位组件4包括固定杆41、套筒42、第二弹性件43和第二连杆44，固定杆41连接于第一壳体1内，套筒42套设于固定杆41并沿固定杆41的轴线方向可滑动，第二弹性件43的两端分别与固定杆41和套筒42连接，第二连杆44的第一端转动连接于套筒42，第二连杆44的第二端转动连接于第一连杆31。第一连杆31摆动时，第一连杆31通过第二连杆44拉动套筒42沿固定杆41的轴线方向移动，套筒42拉伸或压缩第二弹性件43从而改变第二弹性件43的形变量，第二弹性件43在自身弹力的作用下带动套筒42复位，套筒42通过第二连杆44拉动第一连杆31进行复位，进一步保证了第一连杆31始终与第二壳体2相接触。
在一些实施例中，第二弹性件43为弹簧。
在一些实施例中，耗能组件3有多个，多个耗能组件3间隔布置；复位组件4有多个，多个复位组件4与多个耗能组件3一一对应，第二连杆44的第二端转动连接于对应的第一连杆31。多个耗能组件3对多处第一填充液11进行推动，使多处第一填充液11均参与摩擦耗能，提高了扇板33对第一填充液11传递机械能的效率和第一填充液11的耗能效率。
如图1和图5所示，在一些实施例中，复位组件4包括一个第二固定块45、一个固定杆41、两个套筒42、两个第二弹性件43和两个第二连杆44，第二固定块45连接于第一壳体1内壁，固定杆41连接于固定块且固定杆41的两端分别置于第二固定块45的两侧，两个套筒42分别套设于固定杆41的两端，两个第二弹性件43与两个套筒42一一对应，且第二弹性件43的两端分别与固定杆41和对应的套筒42连接，两个第二连杆44分别与两个套筒42一一对应，且两个第二连杆44分别与两个耗能组件3一一对应，第二连杆44的一端 可转动连接于对应的套筒42，第二连杆44的另一端可转动连接于对应的第一连杆31。

如图1所示，在一些实施例中，非线性混合耗能减振阻尼器还包括定位组件6，定位组件6包括定位件61、滑动件62和第三弹性件63，定位件61适于与建筑物100的侧壁连接，滑动件62的第一端连接于第一壳体1和/或第三壳体5，滑动件62的第二端连接于定位件61并沿滑动件62的轴线方向可滑动，第三弹性件63的一端连接于定位件61，第三弹性件63的另一端连接于第一壳体1和/或第三壳体5；定位组件6有多个，多个定位组件6在第一壳体1和/或第三壳体5上间隔分布。定位件61、第三弹性件63和滑动件62将建筑物100振动传递至第一壳体1和第三壳体5内，使第一壳体1和第三壳体5内的零部件对建筑物100机械能进行损耗。
在一些实施例中，第三弹性件63为弹簧，第三弹性件63套设于滑动件62。
如图1所示，在一些实施例中，定位组件6有两个，其中一个滑动件62连接于第一壳体1，另一个滑动件62连接于第三壳体5。
