The invention discloses a rim propeller which comprises a stator and a rotor connected to the stator through a water lubricated bearing, the stator is composed of a flow guide section, a stator armature, an end cover and a sealing cylinder, and the rotor is composed of a rotor yoke part, a rotor bearing section, a rotor permanent magnet pole, a rotor sealing cylinder and blades. The pressurizing system is composed of a gas filling pump set, a gas tank, an energy accumulator and a pressure valve which are connected through a pressurizing pipeline, a gas filling deformation device composed of one or more gas filling deformation bodies and a gas filling connector is arranged in an air gap channel formed by the stator and the rotor, and the gas filling deformation bodies are arranged on the stator through a supporting and fixing device. And the pressurizing pipeline is connected with an air-entrapping interface of the inflatable deformable body. By means of the inflation deformation device, real-time opening and closing of a stator and rotor air gap channel and a guide vane supporting structure bearing channel can be achieved, foreign matter such as silt and fishing nets in a water area is prevented from entering, and the reliability of the rim propeller can be remarkably improved on the premise that the performance of the propeller is guaranteed.

    本发明公开了一种轮缘推进器,包括定子和通过水润滑轴承连接在定子上的转子,定子由导流段、定子电枢、端盖、密封筒组成,转子由转子轭部、转子轴承段、转子永磁磁极、转子密封筒及桨叶组成,还包括由加压管道连接的加气泵组、气罐、蓄能器及压力阀组成的加压系统,所述的定子与转子形成的气隙通道内设置有由一个或多个充气变形体和加气接口组成的充气变形装置,所述的充气变形体通过支撑固定装置设置在定子上,所述加压管道与充气变形体的加气接口连接。本发明通过充气变形装置,可以实现定转子气隙通道及导叶支撑结构轴承通道的实时开闭,防止水域中泥沙、渔网等异物的进入,通过该发明在保证推进器性能的前提下,能够显著提高轮缘推进器可靠性。
