Description

一种模块化磁力耦合电力吊舱推进器 技术领域
本发明涉及船舶海工领域的一种推进装置，尤其是涉及一种模块化磁力耦合电力吊舱推进器。
背景技术
目前，船舶动力主要采用传统的柴油机—主轴--螺旋桨方式获取，而传统的轴式螺旋桨的效率低、排放高、振动噪声大，不能满足最新的排放标准，也无法很好地满足绿色船舶要求。随着船舶电力系统与电机的发展，电力推进方式体现出了显著的优势。与传统的轴式螺旋桨推进系统相比，电力推进方式的特点在于船舱可以灵活布局，不受制于主轴对空间的要求；另外可以降低碳排放，符合绿色船舶的概念；推进方向可以控制，实现一浆多用，既可以推进也可以转向。但是，目前国内大功率吊舱推进器基本没有实现产业化。
目前电力吊舱推进器在豪华邮轮、渡轮、拖轮、海工平台等应用较多。目前大部分吊舱推进器密封方式依然采用机械密封—动密封方式对电机轴进行密封，比如专利CN201820075788.6、CN201610195099.4等对吊舱推进器的密封结构进行保护。目前吊舱推进器的减阻方式大部分采用增加鳍、设置消涡装置及设计外形的方式进行，比如专利CN202010586516.4设置了专门的消涡装置；专利CN202010210753.0通过推力鳍和十字尾鳍进行消涡；专利CN202010542885.3在舱体表面设置有防涡螺旋线进行消涡。目前大部分吊舱推进器电机的散热依靠外部水流进行散热。这些吊舱推进器在减阻、密封、散热等方面均存在一些问题。
发明内容
发明目的：针对上述问题，本发明的目的是提供一种模块化磁力耦合电力吊舱推进器，保证密封性，提高减阻、散热效果。
技术方案：一种模块化磁力耦合电力吊舱推进器，包括箱体、主舱体、透平舱，箱体安装于主舱体的外周面上并通过多种管路与其内部连通，主舱体内部设有电机、磁力耦合盘一，电机固定于主舱体内，其电机主轴与磁力耦合盘一同轴连接，透平舱的内部设有透平主轴、磁力耦合盘二，透平主轴通过轴承安装于透平舱内部，其一端与磁力耦合盘二同轴连接，透平舱的一端通过法兰盘与主舱体的一端连接，使磁力耦合盘一与磁 力耦合盘二同轴间隔相对并磁力相吸连接，透平舱的外周设有透平叶片，透平叶片的内圈延伸至透平舱内并与透平主轴连接。
进一步的，箱体的一侧壁上安装有高压气体管路，主舱体与透平舱连接处的外周面上安装有周向布置的高压空气管路，高压气体管路与高压空气管路连通，高压空气管路上分布有多个出气口。
高压空气可以从高压空气管路的出气口高速喷出，在主体舱表面形成一层气膜，从而降低推进器的阻力。形成气膜的气体管路在主舱体表面以及箱体的壁面，该管路没有进入主舱体内部，从而保证舱体的水密性。
最佳的，出气口的口径为1mm～2mm，相邻两个出气口的间隔为2～3mm。
高压气体喷出以后会在吊舱外壁形成一层空气泡膜。
进一步的，主舱体与透平舱的连接面之间设有钛合金隔离层，钛合金隔离层密封主舱体与透平舱的连接端面，磁力耦合盘一、磁力耦合盘二与钛合金隔离层之间分别具有间距A、间距C。
磁力耦合盘一、磁力耦合盘二相互吸引，两者与钛合金隔离层之间都有距离，因此可避免产生摩擦。
最佳的，钛合金隔离层的厚度为1～2mm。
最佳的，磁力耦合盘一、磁力耦合盘二与钛合金隔离层之间的间距A、间距C均为1～2mm。
间距越大磁力耦合盘镶嵌的永磁体的磁场强度要求越大。要求磁力耦合盘能够传递的扭矩大于吊舱推进器叶轮产生的扭矩。
设计时首先确定叶轮产生的扭矩，再根据公式
其中，μ0真空磁导率是个常数,μr相对磁导率远远大于1，B的磁场强度，n是单个磁力耦合盘磁铁个数，S是单个磁铁的面积，Rc磁力耦合盘的有效半径，推导所需的磁场强度，得到单个磁铁的参数。
进一步的，箱体内部设有大流量气体进气管路、大流量气体出气管路、大电流电缆管路、信号线管路，大流量气体进气管路、大流量气体出气管路分别与电机的内部连通，大电流电缆管路、信号线管路分别与电机连接。
各管路相互独立设置，箱体内部油、气、电管路是相互独立的，互不干扰，便于维 修。单独的气体管路进入电机内部，对电机内部的热量进行热交换，并将热量带出主舱体，同时舱体周围的海水也可以为整个主舱体降温。
进一步的，大流量气体进气管路通过高压进气泵与船内部的空气热量交换设备连接，大流量气体出气管路通过高压出气泵与船内部的空气热量交换设备连接。
空气热量交换设备为船舶自带设备。
空气由热量交换设备进入高压进气泵，再由高压进气泵进入大流量气体进气管路，由大流量气体进气管路进入主舱体内部，然后进入大流量气体出气管路，通过高压出气泵将热量带走进入热量交换设备，如此循环将电机内部的热量带出主舱体，同时主舱体周围的海水也可以为整个舱体降温。
最佳的，主舱体内部安装有温度传感器、湿度传感器、水位传感器，透平舱内安装有转速传感器，四者分别与大电流电缆管路、信号线管路连接。
转速传感器实时采集透平转速，温度传感器、湿度传感器、水位传感器可以实时监控主舱体内部的温湿等参数，以做好预警措施。
进一步的，主舱体为圆桶状，其另一端安装有后整流罩，透平舱的另一端安装有前整流罩，前整流罩位于透平叶片的外侧。
主体舱表面是光滑的，且圆桶结构加工难度低。
有益效果：与现有技术相比，本发明的优点是：
(1)主体舱与透平舱之间是通过磁力耦合传递扭矩，电机主轴无复杂的动密封结构。
(2)主体舱是完全静密封，不存在渗水的可能性，很好的保证了设备的可靠性。
(3)该电力吊舱推进器主体表面有气膜形成机构，可以在主体舱表面形成一层气膜，大大降低流体阻力。
(4)主体舱内部空气管路预留好，高压空气完全满足电机内部散热需求。
(5)模块化设计，结构简单，安装方便。

具体实施方式
下面结合附图和具体实施例，进一步阐明本发明，应理解这些实施例仅用于说明本发明而不用于限制本发明的范围。
一种模块化磁力耦合电力吊舱推进器，如图1～5所示，包括箱体101、主舱体201、透平舱301。
主舱体201为圆桶结构，其外表面为光滑面，易于加工。主舱体201内部设有电机202、磁力耦合盘一205，电机202固定于主舱体201内，其电机主轴204与磁力耦合盘一205同轴连接。
透平舱301的内部设有透平主轴305、磁力耦合盘二304，透平主轴305通过轴承安装于透平舱301内部，其一端与磁力耦合盘二304同轴连接，透平舱301的一端通过法兰盘302与主舱体201的一端连接，使磁力耦合盘一205与磁力耦合盘二304同轴间隔相对并磁力相吸连接，透平舱301的外周设有透平叶片306，透平叶片306的内圈延伸至透平舱301内并与透平主轴305连接。
主舱体201另一端安装有后整流罩208，透平舱301的另一端安装有前整流罩307，前整流罩307位于透平叶片306的外侧。
箱体101安装于主舱体201的外周面上，箱体101上设有内部管路和外部管路，两者相互独立。其中，箱体101内部设有多种与主舱体201内部连通的管路，包括大流量气体进气管路103、大流量气体出气管路104、大电流电缆管路105、信号线管路106，大流量气体进气管路103、大流量气体出气管路104分别与电机202的内部连通，大电流电缆管路105、信号线管路106分别与电机202连接。
大流量气体进气管路103通过高压进气泵与船内部的空气热量交换设备连接，大流量气体出气管路104通过高压出气泵与船内部的空气热量交换设备连接。
空气热量交换设备为船舶自带设备。
空气由热量交换设备进入高压进气泵，再由高压进气泵进入大流量气体进气管路，由大流量气体进气管路103进入主舱体内部，然后经过一段时间后进入大流量气体出气管路104，通过高压出气泵将热量带走进入热量交换设备，如此循环将电机内部的热量带出主舱体，同时主舱体周围的海水也可以为整个舱体降温。
电机202内部积累的热量主要依靠大流量气体进气管路103、大流量气体出气管路 104两路气体管路与主舱体201外部的水流进行散热，由于气体压力远远大于海水压力，因此也可以保证电机202内部压力大于外部水压，从而可以保证海水不会进去主舱体201内。
箱体101外的一侧壁上安装有高压气体管路102，主舱体201与透平舱301连接处的外周面上安装有周向布置的高压空气管路206，高压气体管路102与高压空气管路206连通，高压空气管路206上分布有多个出气口207，出气口207的口径为1～2mm，相邻两个出气口207之间的间隔为2～3mm。
高压空气可以直接从高压气体管路102通到高压空气管路206，与对电机202进行空气散热的气流分开，保证主体舱201的气密性。
出气口207直径很小，会喷出高压空气，在主体舱201表面行程微小的气体层，从而降低主舱体201的海水阻力，提高系统的推进效率。
主舱体201内部还安装有温度传感器、湿度传感器、水位传感器，可以实时监控主舱体201内部的温湿等参数，以做好预警措施。透平舱内部安装有不怕海水腐蚀的转速传感器，实时采集透平转速。温度传感器、湿度传感器、水位传感器、转速传感器分别与大电流电缆管路105、信号线管路106连接。
主舱体201与透平舱301的连接面之间设有钛合金隔离层303，钛合金隔离层303密封主舱体201与透平舱301的连接端面，法兰盘302与钛合金隔离层303之间都有密封圈进行密封，磁力耦合盘一205、磁力耦合盘二304与钛合金隔离层303之间分别具有间距A、间距C。
钛合金隔离层303的厚度为1～2mm，磁力耦合盘一205、磁力耦合盘二304与钛合金隔离层303之间的间距都是1～2mm,间距越大磁力耦合盘镶嵌的永磁体的磁场强度要求越大。
钛合金可以传递磁场，并且强度高。1～2mm厚的钛合金隔离层303可以很好的将海水阻挡在主体舱201外面，确保海水不会进入主体舱201。电机202与透平之间的扭矩传递完全依靠磁力耦合盘一205、磁力耦合盘二304的磁力耦合传动，这样电机主轴204与透平主轴305无接触式实现扭矩传递，动密封变成了由一层钛合金隔离层303形成的静密封，从而提高了密封的可靠性。
本推进器的工作流程如下：
(1)首先高压空气进入管路，通过高压空气管路上分布有多个出气口形成气膜。
(2)散热高压空气进入管路，通过大流量气体进气管路、大流量气体出气管路对电机进行循环散热。
(3)信号与检测系统通电，通过温度传感器、湿度传感器、水位传感器等测试主舱体内气压、湿度、温度是否满足开机条件，判定主舱体内部是否渗水。
(4)如果反馈结果均满足条件，强电流电路接通启动电机；如果不满足条件，则排查原因，解决问题使满足条件。
(5)推进器开始工作，工作结束后，通过断掉大电流电路停止电机运行。
(6)电机停止后断掉散热高压气体。
