Description

臂式离心机高离心力环境高压液体输送系统 技术领域
本发明属于岩土工程模型试验领域，尤其涉及一种臂式离心机高离心力环境液体输送系统。
背景技术
臂式土工离心机是用于岩土工程物理模拟试验的一种试验设备，其通过高速旋转产生的离心力模拟自重应力，使得吊篮内搭载的岩土体缩尺模型内的应力场与现场大尺寸原型相似，模拟原型岩土结构的受力、变形和破坏，以验证设计方案，进行材料参数研究、验证数学模型及数值分析计算结果、探索新的岩土工程物理现象，在岩土工程领域得到了广泛的应用。目前涉及的相关实验有土石坝管涌、溃坝实验、近海结构稳定性实验、边坡失稳实验、地下洞室变形破坏等。
在溃坝、管涌等涉及水的试验中，需要离心机提供向吊篮内的岩土模型内供水的能力；另外，随着对所研究岩土体深度的增加，在自重应力之外，还需要通过多路液压对所研究的岩土体模型施加轴压、围压等多路压力，模拟其原型的受力状态，提出了对离心机吊篮内多路供油的需求。
臂式离心机的构造是在水平的转臂两端悬挂两个垂直地面的吊篮，该吊篮在旋转前垂直于地面/转臂，方便装载大型实验装置，而在实验中随着离心力的增大逐渐近似平行于地面/转臂，这个角度的变化给向吊篮内的供水、供油带来了一定的困难。传统做法中，离心机的供水、供油管线在离心机转臂末端设置刚性接头，接入柔性的钢丝软胶管向吊篮内输送水、油，利用钢丝胶管的柔性来适应吊篮在两种状态下的角度差异，这段软管称为“吊篮输送软管”。由于软管在实验前和实验中的位置会发生变化，故较难对该段软管进行妥善的加固，整段软管的离心力几乎全部要依靠其与转臂处的接头来承受。然而现存的高压油管和配套接头普遍为抗内压设计，而无抗拉强度的指标和能力，在大容量、高离心力的离心机上，吊篮输送软管及接头的安全性无法保证。随着实验装置能力的提升和离心力的升高，吊篮输送软管及接头存在最终无法承受超高的离心负载而有发生密封失效甚至断裂的风险。
例如在拟建的国家重大科技基础设施“超重力离心模拟与实验装置”上，拟建的模型机最高离心力为300倍地球重力，有效旋转半径为6.4m，吊篮输送软管悬空段长度为2.8m，经计算在正常负载下13mm内径的软管受力约为370公斤，这超出了高压软管的设计能力要求，迫切需求提出新的离心机高压液体输送方案。
发明内容
本发明目的在于针对现有技术的不足，提出一种臂式离心机高离心力环境高压液体输送系统。
本发明的目的是通过以下技术方案来实现的：一种臂式离心机高离心力环境液体输送系统，该系统包括离心机主机、地面液源、地面输送管线、离心机底置旋转接头、离心机转臂输送管线、转臂-吊篮销轴、吊篮旋转接头、吊篮输送管线和吊篮管线接出口；
所述离心机底置旋转接头固定在离心机主机底部，其定子端与地面液源通过地面输送管线连接，离心机旋转过程中保持不动；其转子端与离心机转臂输送管线的一端相连，在离心机旋转过程中随离心机的旋转而旋转；离心机转臂输送管线另一端与吊篮旋转接头相连；
所述吊篮旋转接头由定子、定子输入接口、转子、转子输出接口组成；其中转子表面刻有若干个弧形流槽；每个弧形流槽底部与转子输出接口连通；定子套在转子外面；定子在对应转子上每个弧形流槽的位置开孔安装定子输入接口；
所述吊篮旋转接头的定子固定连接在转臂-吊篮销轴上，在吊篮的旋转过程中，定子保持不动；定子输入接口与离心机转臂输送管线连接；
所述吊篮输送管线固定在吊篮上，其在吊篮中的接口为吊篮管线接出口；吊篮输送管线与吊篮旋转接头的转子输出接口刚性相连；在吊篮旋转过程中，所述吊篮输送管线带动吊篮旋转接头的转子使其共同旋转，在转子相对定子转动的过程中定子输入接口始终与对应的转子上弧形流槽连通，进而与转子输出接口连通。
进一步地，所述地面液源包括液压源、水源。
进一步地，地面输送管线与离心机底置旋转接头的定子端通过密封螺纹口连接。
进一步地，弧形流槽的弧度为θ，转子的一个圆周上共均匀地布置3个弧形流槽，该3个弧形流槽为一组，每组流槽之间设置有轴向环形密封组件，每组的3个流槽周围设置有圆角矩形的密封组件。
进一步地，弧形流槽的弧度θ应满足：
Figure PCTCN2022073802-appb-000001
其中，d为定子输入接口的内径，D为转子的外径，f为流槽之间的环向安全密封间距。
进一步地，定子与转子之间通过滚珠轴承配合相对90度旋转。
本发明具有以下优点和积极效果：
1)本发明中的液体输送管线中采用旋转接头适应臂式吊篮离心机工作前后的吊篮-转臂角度变化，满足离心机水电油气输送需求
2)相比传统方案各机载装置需与转臂端头进行长距离软管连接，并需额外加固，转臂-旋转接头和旋转接头-吊篮中的管路均可采用刚性管，走线布置和加固均固化设计，相对传统的高压软管接入吊篮的方案可将负荷离心力荷载提高到500g以上。
3)由于所提出的吊篮旋转接头需以类似于悬臂的方式固定于吊篮销轴处，该处离心力较大，传统旋转接头过重、体积过大加固困难，且侵占了吊篮内原本可以用于实验的空间。故针对离心机吊篮相对转臂仅固定旋转90度的工况设计了新型旋转接头，改环形槽为弧形槽，一环拓展为三环，旋转接头和体积和重量约减为原来的1/3，使得离心机销轴处旋转接头的可行性和可通管路数均大大增加。
