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.
