本发明提出一种导流装置100。
在本发明实施例中，结合图1至图4所示，该导流装置100，用于潜水设备300，潜水设备300包括推进器主体301和涵道螺旋桨302，导流装置100设于推进器主体301和涵道螺旋桨302之间，导流装置100设置有入水端10和出水端30，入水端10设于导流装置100靠近推进器主体301的一侧，出水端30设于导流装置100靠近涵道螺旋桨302的一侧，入水端10与出水端30连通，并形成有水流流道，其中入水端10与出水端30之间设置有第一导流结构51，第一导流结构51设置有第一导流面511，第一导流面511呈弧形设置，第一导流面511用于引导水流流向涵道螺旋桨302。
在一实施例中，第一导流结构51的设置，用于使水流从入水端10进入水流通道后，在出水端30流出的过程中，能被第一导流结构51导向涵道螺旋桨302，直接进入到涵道螺旋桨302内，以提高涵道螺旋桨302的工作效率；第一导流面511呈弧形设置，用于使水流在被第一导流结构51的第一导流面511导向的时候，能保持水流的流速，从而使水流流体保持一个较好的流动状态，水流的流速与第一导流面511的弧形形状的相互配合，可以避免湍流的产生而 导致的能量损失，并且在此不对第一导流面511的形状进行限定，第一导流面511的形状只需设计成流线型即可，可以根据水流具体的流速来选择相适配的第一导流面511的形状，并且入水端10为环形入水端10，水流会从环形的入水端10进入到水流通道，增大了水流的入流空间，提高了导流装置100的导流效率。
具体地，弧形设置的第一导流面511相比较没有弧形设置的第一导流面511，没有弧形设置的第一导流面511会使水流产生流动分离，进而产生湍流和旋涡，而这部分湍流和旋涡会占据入水端10的水流一定的入流空间，导致这部分空间为无效入流空间，压缩了水流的有效入流空间。相反地，呈弧形设置的第一导流面511会消除水流的流动分离，因此不会有湍流和旋涡的产生，从而增加了水流的有效入流空间。
本实施例的技术方案通过设置第一导流结构51，第一导流结构51上设置有呈弧形的第一导流面511，以使水流进入水流通道后，能被导向涵道螺旋桨302，从而能保持水流在水流通道时的较好的流速，进而提高流场的稳定性，减少水流与第一导流结构51的脱离，进而减小水流进入涵道螺旋桨302内的能量损失，提高涵道螺旋桨302工作的效率。
在本发明一实施例中，结合图2至图4所示，第一导流结构51呈环状设置，第一导流结构51的内径自入水端10朝向出水端30逐渐减小。
在一实施例中，第一导流结构51呈环状设置，用于使水流从入水端10的周向进入后，水流均能沿第一导流结构51进行流动，从而被第一导流结构51进行引导导向，保证了整体水流在水流流道内的导向，并且第一导流结构51的内径自入水端10朝向出水端30逐渐减小，并且内径缩小至朝向涵道螺旋桨302的几何中心，以使水流能更好地被导向涵道螺旋桨302的几何中心，大大提高了流向涵道螺旋桨302的几何中心的水流流量，避免水流进入涵道后的损失，从而提高了涵道螺旋桨302的工作效率，进而提高了潜水设备300的工作效率。
在本发明一实施例中，结合图1所示，导流装置100包括第一导流件50和连接环70，第一导流件50处于入水端10与出水端30之间，并与推进器主体301连接，第一导流结构51设于第一导流件50上，连接环70与涵道螺旋桨302连接，并与第一导流件50连接。
在一实施例中，第一导流件50处于入水端10与出水端30之间，以使水流从入水端10进入后，能在水流流道被第一导流件50导向出水端30的涵道螺旋桨302，连接环70的设置起涵道螺旋桨302与导流装置100的连接作用，并且连接环70与涵道螺旋桨302之间为可拆卸连接，拆装方便，第一导流件50和连接环70的结构简单，生产成本低，导流与连接效果好。
在本发明一实施例中，结合图4所示，第一导流件50背离推进器主体301的一侧设有第一传动轴通孔53。
在一实施例中，第一传动轴通孔53的设置使得传动轴能穿设导流装置100，进而穿设于涵道螺旋桨302，以使传动轴能将推进器内产生的动能传递给涵道螺旋桨302，使得涵道螺旋桨302能在水下进行高速运转，给予潜水设备300在水下运转的动力。
在本发明一实施例中，结合图3与图4所示，第一导流件50靠近推进器主体301的一侧设有连接通孔55。
在一实施例中，连接通孔55的设置，以使推进器主体301与第一导流件50能够通过螺丝穿设于连接通孔55进行连接，使得连接的稳定性更高，结构简单，加工成本低。
在本发明一实施例中，结合图2所示，入水端10与出水端30之间还设置有第二导流结构91，第二导流结构91包括第一迎流面911和第二导流面913，第一迎流面911与第二导流面913均处于入水端10与出水端30之间，并两者呈夹角设置，第一迎流面911用于使水流保持进入入水端10的流动方向，第二导流面913用于引导水流流向出水端30。
在一实施例中，第二导流结构91设于入水端10与出水端30之间，使得水流能被导向出水端30，第一迎流面911的设置，用于使水流从入水端10进入，经过第一迎流面911时，保持一定的流动方向进入到水流流道内，而第二导流面913的设置，用于使水流经过第一迎流面911后，能够被导向出水端30，以使水流在进入水流通道时，能够保持一定的入流方向，并且使得水流经过第二导流结构91时，始终能被导向出水端30，以此提高了涵道螺旋桨302的工作效率。
在本发明一实施例中，结合图4至图5所示，第一迎流面911和第二导流面913均呈弧形设置。
在一实施例中，第一迎流面911和第二导流面913的弧形设置，用于使水流经过第一迎流面911和第二导流面913时，能保持水流的流速，从而使水流流体保持一个较好的流动状态，水流的流速与第一迎流面911和第二导流面913的弧形形状的相互配合，可以避免湍流的产生而导致的能量损失，并且在此不对第一迎流面911和第二导流面913的形状进行限定，第一迎流面911和第二导流面913的形状只需设计成流线型即可，可以根据水流具体的流速来选择相适配的第一迎流面911和第二导流面913的形状。
具体地，弧形设置的第一迎流面911和第二导流面913相比较没有弧形设置的第一迎流面911和第二导流面913，没有弧形设置的第一迎流面911和第二导流面913会使水流产生流动分离，进而产生湍流和旋涡，而这部分湍流和旋涡会占据入水端10的水流一定的入流空间，导致这部分空间为无效入流空间，压缩了水流的有效入流空间。相反地，呈弧形设置的第一迎流面911和第二导流面913会消除水流的流动分离，因此不会有湍流和旋涡的产生，从而增加了水流的有效入流空间。
在本发明一实施例中，结合图1至图2所示，导流装置100还包括多个第二导流件90，第二导流结构91分别设于多个第二导流件90上，多个第二导流件90与第一导流件50连接，并与连接环70连接，多个第二导流件90间隔设置，并处于入水端10与出水端30之间。
在一实施例中，多个第二导流件90间隔设置于入水端10，并设有第二导流结构91，以使水流从入水端10进入后，能被第二导流件90导向水流流道，并保持较好的流速，同时第一导流件50与连接环70通过多个第二导流件90进行连接，无需再设置额外的连接结构，结构简单，加工成本低，导流与连接的效果佳。
在本发明一实施例中，结合图1与图6所示，涵道螺旋桨302包括桨盘303和桨叶304，桨叶304间隔设于桨盘303的外周，出水端30朝向桨盘303，第一导流结构51用于引导水流导向桨盘303。
在一实施例中，桨叶304间隔设于桨盘303的外周，桨盘303为涵道螺旋桨302平面内以螺旋桨中点为圆心，大致以螺旋桨半径为半径的圆面，水流在第一导流结构51的引导下从出水端30流出，导向涵道螺旋桨302的几何中心位置，即桨盘303所在的位置，能避免了水流的能量浪费，大大提高了涵道螺旋 桨302的工作效率。
在本发明一实施例中，结合图6所示，桨盘303的中心设有第二传动轴通孔305。
在一实施例中，第二传动轴通孔305设置使得传动轴能穿设导流装置100后，进而穿设于第二传动轴通孔305，以使传动轴能将推进器主体301内产生的动能传递给涵道螺旋桨302的桨盘303，使得涵道螺旋桨302的桨叶304能在水下进行高速运转，给予潜水设备300在水下运转的动力。
此外，本发明还提出一种潜水设备300，结合图1所示，潜水设备300包括上述推进器主体301、涵道螺旋桨302及导流装置100，导流装置100设于推进器主体301与涵道螺旋桨302之间。
